Description

Positioning method and device for driving structure of ballpoint pen refill

technical field

The present invention relates to a positioning method and its device for the driving structure of the ball pen refill, in particular to a method and its device which can form the positioning when the pen refill is stretched out for writing, so as to prevent it from retracting improperly.

Background technique

The transmission structure of the existing rotary ballpoint pen refill, as shown in Figure 1, is provided with a hollow sleeve 1, transmission body 2, pen core 3, rotating cylinder 4, pen tube 5 and pen cap 6, wherein, the cover The cylinder 1 is provided with a roughly V-shaped split groove 11, and the transmission body 2 is provided with a clamping post 21 at the bottom edge, so that the transmission body 2 is placed behind the sleeve 1, and the clamping post 21 can be exposed through the split groove 11. When the transmission body 2 is driven by the pen cap 6 to rotate, the clamping post 21 can move up and down along the sectional groove 11, so that the pen core 3 locked on the transmission body 2 protrudes from the bottom end of the pen tube 5 for writing or writing. It is retracted in the pen tube 5 to facilitate carrying.

This traditional transmission structure is to prevent the retraction phenomenon of the pen core 3 due to the withdrawal of the clamping column 21 when the writing state is in place. Usually, the bending section of the split groove 11 is provided with a pointed protrusion to form a stop to prevent the clamping column 21 from retreating upwards, but This kind of mode can not really effectively prevent the retraction of the pen core 3 .

Therefore, some operators put a spring 22 (as shown in FIG. 2 ) through the transmission body 2, and the tension of the spring 22 makes the clamping column 21 positioned to prevent it from retreating. Although it can improve the traditional transmission structure of FIG. 1 Missing, but due to the low price of pens, the market is quite competitive, and the addition of components requires additional assembly man-hours, thus increasing the cost.

Contents of the invention

The main purpose of the present invention is to provide a positioning method and device for the driving structure of the ballpoint pen refill, so that the refill of the ballpoint pen can be positioned to prevent the refill from retracting when writing.

The positioning method of the driving structure of the ballpoint pen refill of the present invention is mainly to be provided with a sleeve, and the sleeve is provided with a roughly V-shaped sectional groove, so that a transmission body with a clamping post on the bottom edge is placed behind the sleeve. , the clamping column can be exposed through the groove, so that the pen core can be locked on the transmission body, so that when the transmission body rotates, the clamping column can move up and down along the groove of the sleeve, so that the pen core can protrude from the pen tube. For writing, or retracted in the pen tube, it is characterized in that:

When the clamping column of the transmission body moves along the groove of the sleeve to its bending section, the elastic tension formed by the arrangement of the groove connecting pieces on the top edge of the sleeve in different directions is used to push against the transmission body to form the positioning of the clamping column, so as to Prevent retraction of the refill.

The positioning device is provided with two or more annular grooves on the top edge of the sleeve, and symmetrical connecting pieces are arranged on the grooves, and the connecting pieces of the grooves at the upper and lower positions are mutually formed. Arrangement in different directions to form proper elasticity.

Said positioning device, wherein the symmetrical connecting pieces provided in the upper and lower position grooves are in different directions of 90 degrees to form better elasticity.

The invention will be described in detail below with specific examples in conjunction with the accompanying drawings.

Detailed ways

Referring to Fig. 3 and Fig. 4, the present invention is mainly provided with a hollow sleeve 1, a transmission body 2, a pen core 3, a rotating cylinder 4, a pen tube 5, and a pen cap 6 of a general ballpoint pen. A V-shaped split groove 11, and a clamping column 21 is provided at the bottom edge of the transmission body 2, so that the transmission body 2 is sleeved behind the sleeve 1, and the clamping column 21 is exposed through the split groove 11 and moves up and down along the split groove 11, so as to Constitute the protruding of the pen core 3 for writing, or retract in the pen tube 5 to facilitate carrying.

The top edge of the sleeve 1 is provided with a telescopic elastic device 100 integrally formed with the sleeve 1. In this embodiment, the device 100 is provided with two or more spaced annular grooves 12, and Groove 12 is provided with symmetrical connection piece 13, and wherein, the connection piece 13 of upper and lower position groove 12 is mutually different directions (in this embodiment, is the different direction of 90 degrees mutually), to form proper elasticity, makes When the clamping column 21 moves down along the split groove 11 and engages in the bending section of the split groove 11, the elastic tension of the groove 12 pushes against the transmission body 2 to form a positioning function, preventing the clamping column 21 from retreating, and relatively preventing the pen The core 3 retracts when writing.

Please refer to Figs. 5 to 7 at the same time. When the present invention is in use, when the transmission body 2 is driven by the pen cap to rotate, the clamp post 21 moves down along the groove 11 of the sleeve 1, and the pen core 3 slowly stretches out (as shown in Fig. 5), and when the clamping column 21 moves to the pointed portion 111 of the split groove 11, the refill 3 is fully stretched out, and the telescopic elastic device 100 arranged on the top edge of the sleeve 1 is pressed by the top edge of the transmission body 2 And produce tightening (as shown in Figure 6), and when the transmission body 2 continues to rotate, the clamping post 21 promptly moves to the bending section through the sharp protrusion 111, so that the telescopic elastic device 100 will no longer be squeezed by the transmission body 2 And stretch, so that the transmission body 2 is supported by the elastic tension of the stretchable elastic device 100, so that the clamping column 21 is positioned at the bending section of the split groove 11, so as to prevent the pen core 3 from retracting improperly when writing.

To sum up, the present invention uses the telescopic elastic device disposed on the sleeve to prevent the pen core from retracting when the ballpoint pen is writing.
