Referring to fig. 1 to 13, the present invention provides a silent press pen, comprising: the pen comprises a pen holder 1, a pen core 2, an elastic part 3 and a push telescopic mechanism. The pen holder 1 comprises an upper pen shell and a lower pen shell, wherein the upper pen shell is hollow and tubular, the upper end of the lower pen shell is connected to the upper pen shell through threads, and the lower end of the lower pen shell is provided with a conical head. The pen core 2 is arranged in the inner cavity of the pen holder 1, and the pen point of the pen core 2 is positioned in the conical head of the lower pen shell. The elastic component 3 is a spring, and the spring is sleeved at the pen point of the pen core 2. The diameter of one end of the pen core 2 close to the pen point is reduced, so that a first stepped surface is formed with the body of the pen core 2, the upper end of the elastic component 3 is elastically abutted against the stepped surface, and the lower end of the elastic component 3 is elastically abutted against the inside of the conical head of the lower pen shell. The pressing telescopic mechanism is arranged between the pen holder 1 and the pen core 2, and is matched with the elastic part 3 when being pressed to drive the pen core 2 to move up and down in the pen holder 1.

Referring to fig. 2 to 4, the push telescopic mechanism includes a push core 4, a rotary wheel 5 and a catch wheel 6, wherein the push core 4 is limited in the pen holder 1 in a vertically sliding manner, and the top end of the pen core 2 is propped against the bottom of the push core 4. The rotating wheel 5 and the baffle wheel 6 are both in a ring shape and are sleeved on the pressing core 4.

Wherein, pen-holder 1 is provided with the arc protruding muscle for fender wheel 6 along the inner wall round, and fender wheel 6 is provided with the arc recess along the periphery wall round, and fender wheel 6 is realized with pen-holder 1 relative fixed with the arc protruding muscle through the arc recess on it with tight fit mode.

The pen holder 1 is provided with an annular boss 101 along the inner wall, and the rotating wheel 5 is arranged on the annular boss 101 and is in clearance fit with the inner circumferential wall of the pen holder 1; in addition, the runner 5 is arranged below the baffle wheel 6, and a certain gap is reserved between the top of the runner 5 and the bottom of the baffle wheel 6, so that the runner 5 is limited between the annular boss 101 and the bottom of the baffle wheel 6, and the runner 5 is not influenced to perform rotary motion.

Referring to fig. 2 and 7, a pressing rod 403 integrally extends upward from the middle of the upper end surface of the knock block 4, and the pressing rod 403 passes through the catch wheel 6 to be exposed at the top of the barrel 1 so as to be pressed. The diameter of the pressing rod 403 is smaller than the diameter of the body of the pressing core 4, and a second step surface is arranged between the body of the pressing core 4 and the pressing rod 403; the upper end of the baffle wheel 6 extends towards the center to form an annular baffle 601, the pen core 2 pushes the pressing core 4 upwards under the elastic force of the elastic part 3, and the pen core is stopped and limited on the bottom surface of the baffle 601 upwards through the second step surface.

Referring to fig. 4 and 7, the pressing rod 403 is provided with two symmetrical limiting sliding grooves 4031 along the axial direction, the annular baffle 601 is provided with two protruding blocks 602 along the inner peripheral wall corresponding to the two limiting sliding grooves 4031, the two protruding blocks 602 extend into the corresponding limiting sliding grooves 4031, and the pressing core 4 is slidably matched with the protruding blocks 602 through the limiting sliding grooves 4031 thereon, so that the pressing core 4 is limited from rotating, and the pressing core 4 can only vertically move up and down.

Referring to fig. 5 and 6, a guide rail 401 connected end to end is vertically provided on the outer circumferential surface of the knock core 4, a slider 501 is integrally formed on the inner wall of the runner 5, the slider 501 extends into the guide rail 401, and the slider 501 can move unidirectionally along the guide rail 401 when the knock core 4 is pushed.

Specifically, the pressing core 4 is recessed inward along the outer peripheral surface to form a groove, and the contour shape of the groove meets the movement track requirement of the slide block 501; in addition, the pressing core 4 is provided with a stop block 402 which is not connected with the inner wall of the groove in the middle of the groove, so that a guide track 401 is formed on the outer side of the stop block 402 in a circle.

Further, the guide track 401 is provided with a home position 4011, a locking position 4012, an extending high point 4013 and a retracting high point 4014, the home position 4011 is located at the bottom of the guide track 401, the locking position 4012 is located on the locking position block 402, and the extending high point 4013 and the retracting high point 4014 are located on two sides above the locking position 4012 respectively. When the slider 501 is positioned on the home position 4011 (as shown in fig. 8), the pen core 2 is in a retracted state. When the pressing force is applied to the pressing core 4, in the process that the pressing core 4 drives the pen core 2 to move downwards, the sliding block 501 positioned in the original position 4011 slides relatively along the guide track 401 (as shown in fig. 9), the rotating wheel 5 rotates until the sliding block 501 reaches the high extending point 4013 (as shown in fig. 10), and in the process, the elastic component 3 is compressed to store energy; after the pressing force is released, under the elastic force of the elastic component 3, the pen core 2 pushes the pressing core 4 to move upwards, so that the sliding block 501 falls into the locking position 4012 (shown in fig. 11) from the extending high point 4013, and the pen core 2 is in a writing state. When the pressing core 4 applies pressing force again, in the process that the pressing core 4 drives the pen core 2 to move downwards, the sliding block 501 positioned at the locking position 4012 slides relatively along the guide track 401, and the rotating wheel 5 rotates until the sliding block 501 reaches the retraction high point 4014 (as shown in fig. 12), and meanwhile the elastic component 3 is compressed to store energy; after the pressing force is released, under the elastic force of the elastic component 3, the pen core 2 pushes the pressing core 4 to move upwards, so that the sliding block 501 slides relatively along the guide track 401 (as shown in fig. 13), and returns to the original position 4011 from the retraction high point 4014.

Still further, with continued reference to fig. 5, the stop block 402 has a downwardly pointing arrow shape, and the stop block 402 has a first tip 4023 located on the left side, a second tip 4024 located on the right side, a third tip 4025 located at the bottom, and a V-shaped groove located between the first tip and the second tip, where the tip of the V-shaped groove is the location of the locking position 4012. The surface of the stopper block 402 connected between the second tip 4024 and the third tip 4025 is a first guide surface 4021, and the surface connected between the second tip 4024 and the stopper 4012 is a second guide surface 4022. The inner wall of the recess of the plunger 4 has a third guide surface 4015, a fourth guide surface 4016 and a fifth guide surface 4017.

The guide surfaces are described in detail below.

Referring to fig. 5, the first guide surface 4021 is disposed obliquely upward on the right lower side surface of the positioning block 402. The first leading end of the first leading surface 4021 is on the third tip 4025, and the distal end of the first leading surface 4021 is on the second tip 4024, with the distal end being higher than the leading end. The direction of the leading end toward the trailing end as defined in the present application corresponds to the direction in which the slider 501 moves along the guide rail 401 (counterclockwise direction), and the following is the same. The first guide surface 4021 is disposed opposite the home position 4011, that is, the home position 4011 can be projected vertically upward on the first guide surface 4021. It is emphasized that the vertical plane of home position 4011 is offset to the right as compared to the vertical plane of third tip 4025. When the plunger 4 is pressed, since the runner 5 is relatively vertically slid along the guide rail 401 at an initial distance of downward movement of the plunger 4, the runner 5 is not rotated in this process, and thus, in order to ensure that the slider 501 is smoothly relatively slid onto the first guide surface 4021 from the home position 4011, it is necessary to set the home position 4011 to be offset rightward with respect to the third tip 4025. When the slider 501 slides onto the first guide surface 4021 and continues to slide relatively along the first guide surface 4021 in the following movement process, the slider 501 is pushed by the first guide surface 4021 to rotate the rotating wheel 5.

The third guide surface 4015 is located above the end of the first guide surface 4021 (in other words, the second tip 4024), that is to say the end of the first guide surface 4021 can project vertically upwards on the third guide surface 4015. The third guide surface 4015 is arranged obliquely upward, and its end is higher than the head end and extends to the protruding high point 4013. During the downward movement of the plunger 4, the first guide surface 4021 can guide the slider 501 onto the third guide surface 4015, and then guide the slider 501 to the point of extension 4013 via the third guide surface 4015.

The second guide surface 4022 is disposed opposite the protruding high point 4013 and is located below the protruding high point 4013. The second guide surface 4022 is disposed in a downward slant with its head end on the second tip 4024 and its tail end extending to the locking position 4012, and the tail end of the second guide surface 4022 is lower than the head end. It is emphasized that the vertical plane of the high point of protrusion 4013 is offset to the left compared to the vertical plane of the second tip 4024. After the pressing force is released, the elastic member 3 drives the cartridge 2 to push the knock core 4 upward for an initial distance, and since the runner 5 slides vertically relatively along the guide rail 401, the runner 5 does not rotate, and in order to ensure that the slider 501 slides smoothly relatively onto the second guide surface 4022 from the protruding high point 4013, it is necessary to set the protruding high point 4013 to be offset leftward with respect to the second tip 4024. When the slider 501 slides onto the second guide surface 4022 and in the following movement process, the slider continues to slide relatively along the second guide surface 4022, and is guided to the locking position 4012 by the second guide surface 4022; during this sliding, the slider 501 is pushed by the second guide surface 4022, so that the rotating wheel 5 rotates.

The fourth guide surface 4016 is disposed opposite the locking position 4012 and above the locking position 4012. The fourth guide surface 4016 is arranged obliquely upward, its end is higher than the head end, and its end extends to the retraction high point 4014. It is emphasized that the vertical plane of the locking position 4012 is offset to the left compared to the vertical plane of the protruding high point 4013, and that the locking position 4012 can be projected vertically upwards on the fourth guide surface 4016. When the plunger 4 is pressed again, in the initial distance of downward movement of the plunger 4, since the runner 5 slides vertically relatively along the guide rail 401, the runner 5 does not rotate in this process, and in order to ensure that the slider 501 slides smoothly relatively onto the fourth guide surface 4016 from the locking position 4012, it is necessary to set the relatively projecting high point 4013 of the locking position 4012 to be offset leftward, and prevent the slider 501 from sliding back to the projecting high point 4013. When the slider 501 slides onto the fourth guide surface 4016 and in the following movement, the slider continues to slide relatively along the fourth guide surface 4016 and is guided by the fourth guide surface 4016 to the retraction high point 4014; during this sliding, the slider 501 is pushed by the fourth guide surface 4016 to rotate the wheel 5.

The fifth guiding surface 4017 is arranged opposite to the retraction high point 4014 and is located below the retraction high point 4014. In this embodiment, the fifth guiding surface 4017 is composed of a first inclined surface and a second inclined surface that are mutually connected, the first inclined surface and the second inclined surface are both arranged in a downward inclined manner, and the end of the second inclined surface extends to the position 4011. It is emphasized that the vertical plane of the retraction high point 4014 is offset to the left compared to the vertical plane of the first tip 4023, and the retraction high point 4014 can be projected vertically downward on the first slope. When the pressing force is released again, the elastic component 3 drives the pen core 2 to push the press core 4 to move upwards for an initial distance, and the runner 5 does not rotate due to the fact that the runner 5 slides vertically relatively along the guide track 401, so that in order to ensure that the sliding block 501 can slide onto the first inclined plane smoothly relatively from the retraction high point 4014, the retraction high point 4014 needs to be set to be offset leftwards relative to the first tip 4023, and the first tip 4023 is prevented from obstructing the sliding block 501. When the slide 501 slides onto the first incline, the first incline is then changed over to the second incline, and finally the second incline guides the slide 501 to the position 4011. Of course, the fifth guiding surface 4017 may also be a curved surface inclined downward, and the end of the curved surface extends to the position 4011, which can achieve the same technical effect.

It should be noted that, although there is a collision during the sliding of the slider 501 from each point to the corresponding guide surface in the guide rail 401, the collision is not enough to make a sound, because the stroke of the sliding of the slider 501 from each point to the corresponding guide surface is small, each guide surface is an inclined surface, the sliding of the slider 501 falls onto the corresponding guide surface along the inclined surface, the speed of manually pressing the plunger 4 is not very fast, and the hand cannot instantaneously disengage the plunger 4 when the pressing is released, thereby achieving a silent effect.

Wherein, the guide tracks 401 are arranged in two, and the two guide tracks 401 are distributed on the outer peripheral surface of the pressing core 4 in a central symmetry manner. Correspondingly, the runner 5 is provided with two sliding blocks 501, and the two sliding blocks 501 correspondingly extend into the two guide rails 401 one by one, so that the stability of each component in movement can be improved.

In addition, the pressing core 4 is provided with two rail sliding inlets 404 along the lower end corresponding to the two guide rails 401, the rail sliding inlets 404 are in a horn shape with a large lower end and a small upper end, and the rail sliding inlets 404 are communicated with the positions of the original positions 4011 of the guide rails 401 in a one-to-one correspondence manner. When in assembly, the rotating wheel 5 is firstly placed in the penholder 1, and then the pressing core 4 is directly inserted above the rotating wheel 5, so that the sliding block 501 on the rotating wheel 5 slides to the position 4011 along the track sliding inlet 404, and the assembly is very convenient.

Referring to fig. 15, the slider 501 is diamond-shaped, the upper and lower vertex angles thereof are provided with chamfers, and the upper and lower vertex angles are located on the same vertical surface, and the slider 501 slides on each guide surface by means of the upper and lower vertex angles, so that the contact surface is smaller, and the slider can slide more stably. Moreover, pressing the plunger 4 during the process of moving the pen core 2 from the writing state to the retracted state does not require the entire slider 501 to completely pass over the first tip 4023, as long as it is ensured that the plunger 4 is released after the top angle under the slider 501 passes over the first tip 4023, and the elastic member 3 drives the pen core 2 to push the plunger 4 upward so that the first tip 4023 contacts with one inclined surface of the slider 501 (as shown in fig. 14) and pushes the slider 501 to slide along the guide rail 401. Therefore, the use of the diamond-shaped slider 501 allows the guide rail 401 of the knock element 4 to make a smaller rotation angle, so that the knock pen can be made thinner, and also allows the stroke of the movement of the pen core 2 to be reduced.

Therefore, the invention provides a silent pressing pen, a pressing core 4 and a rotating wheel 5 are arranged in a pen holder 1, a guide track 401 is arranged on the outer peripheral surface of the pressing core 4, the rotating wheel 5 is rotatably sleeved on the pressing core 4, a sliding block 501 extending into the guide track 401 is arranged on the rotating wheel 5, and the sliding block 501 can move to a locking position 4012 and an original position 4011 along the guide track 401 when the pressing core 4 is pressed, so that a pen core 2 extends out of or retracts into the pen holder 1, noise is not generated due to collision, and a silencing effect is achieved; meanwhile, the structure design adopted by the application has the advantages of simple structure, convenience in assembling of all parts, low manufacturing cost, high product stability and good hand feel for users, and the pen can be pressed more finely.
