Please refer to FIG. 1, one of the embodiments of the present invention includes a main body 12, an adjustment mechanism 14, an upright unit 16 and an elastic member (not shown). Wherein, the upright unit 16 is disposed inside the body 12, the adjustment mechanism 14 is disposed on the body 12, extends through the body 12 to contact the upright unit 16, and the elastic member is disposed on an inner peripheral surface of the body 12 , And abut on the upright unit 16. The assembly of these components will be described in detail below: Among them, the elastic member may be a leaf spring, which will deform due to the movement of the upright unit 16 and generate a restoring force, thereby maintaining the adjustment mechanism 14 to abut the upright unit 16 . It must be noted that, in fact, the elastic member will be covered by the upright unit 16 in the section of FIG. 1 (that is, the elastic member will not be seen from the section), so it is not shown in FIG. 1 The elastic piece. However, this does not affect those with ordinary knowledge in the technical field to which the present invention belongs, to understand that the elastic member is actually disposed on the inner peripheral surface of the body 12 and is in contact with the upright unit 16.

Please also refer to FIGS. 2A and 2B. The adjusting mechanism 14 includes a cover 142, a braking unit 144, a fixing unit 146, and an adjusting unit 148. The braking unit 144 includes a limiter 441, a guide 443, and a turntable 445. The fixing unit 146 includes a bearing 465, a ring gear 463, and a fixing seat 461. The adjusting unit 148 includes a pivot shaft 481 and an adjusting member 485. The adjusting mechanism 14 can be a height adjusting mechanism or a wind deviation adjusting mechanism.

The fixing base 461 is fixed on the body 12, the ring gear 463 is set in the fixing base 461, the adjusting member 485 is set in the fixing base 461, and passes through an adjusting hole 610 in the center of the fixing base 461. A transmission pin 483 is disposed in a through hole 810 on the pivot shaft 481, and extends into a groove 850 on the adjustment member 485, so that the pivot shaft 481 and the adjustment member 485 form a linkage relationship. Wherein, the outer peripheral wall of the adjusting member 485 has an external thread, and the external thread can cooperate with an internal thread on the inner peripheral wall of the adjusting hole 610. In other words, when the pivot shaft 481 rotates, the adjusting member 485 can be driven to rotate by the transmission pin 483, so that the adjusting member 485 moves axially relative to the fixing seat 461, and thereby moves upright in the body 12 Unit 16. Note that when the adjusting member 485 moves axially relative to the fixing base 461, the range of the distance that it can move is the length of the groove 850.

In addition, a plurality of axial grooves 630 are formed at equal intervals on the inner peripheral wall of the gear ring 463, two blind holes 812 are formed on two protrusions 814 on the pivot shaft 481, each blind hole 812 An elastic member 820, a ball seat 818, and a ball 816 are provided in this order. The ball 816 is disposed on the ball seat 818, and the ball seat 818 is pushed by the elastic force of the elastic member 820, so that the ball 816 abuts the ring gear 463 The grooves 630 on the inner peripheral wall. In other words, when the pivot shaft 481 rotates, it will drive the ball 816 to move between the grooves 630, and then emit a sound (or generate a sense of vibration) to feed back to the user.

On the other hand, the bearing 465 can be fixed outside the fixing seat 461 by a positioning member 510. Wherein, the bearing 465 includes an upper cylinder 650, a lower cylinder 652 and a shaft hole 654, the fixing seat 461, the ring gear 463, the pivot shaft 481 and the adjusting member 485 are accommodated in the lower cylinder 652, the pivot shaft 481 Further extending through the shaft hole portion 654 from the lower cylinder 652, the braking unit 144 is provided in the upper cylinder 650. When assembling the braking unit 144, the turntable 445 is first set in the upper cylinder 650 by a first pressure ring 500, and a first end 4431 of the guide 443 (refer to FIGS. 3A and 3B) passes through in sequence An elastic member 310 and a limiting hole 410 on the limiting member 441 are used to compress the elastic member 310 between a flange on the guide member and the inside of the limiting hole 410. After the limiting member 441 and the guide member 443 are assembled into one body, the limiting member 441 is fixed in the upper cylinder 650 by a second pressing ring 100 and another positioning member 510.

Please refer to FIGS. 3A and 3B at the same time. It should be noted that the turntable 445 includes a slope 450, a positioning part 452, and a dial 454. Specifically, when the braking unit 144 is disposed in the upper cylinder 650, a second end 4433 of the guide 443 abuts the inclined surface 450. The slope 450 includes a high point 4503 and a low point 4501. When the second end 4433 abuts the high point 4503, the elastic member 310 is further compressed by the flange, so that the first end 4431 protrudes out of the limit Piece 441. When the second end 4433 abuts on the low point 4501, the elastic force of the elastic member 310 is released to push the flange, so that the first end 4431 does not protrude from the limiting member 441. The toggle portion 454 is used to rotate the turntable 445 so that the turntable 445 rotates relative to the seat 465 and the guide 443 to switch the second end 4433 to abut the high point 4503 or the low point 4501 of the slope 450, thereby determining the guide Whether the first end 4431 of the lead 443 can protrude from the limiting member 441. The positioning portion 452 is used to position the turntable 445 to fix the second end 4433 of the toggle portion 454 while abutting the high point 4503 or the low point 4501. The dialing part 454 includes a dialing member 4541 and a fixing hole 4543. The dialing member 4541 is fixed to the fixing hole 4543 and extends radially through a groove 6501 formed in the upper cylinder 650 (also That is, the dial portion 454 protrudes out of the seat 465). The positioning portion 452 includes a blind hole 4521, an elastic member 4523 and a sphere 4525. The elastic member 4523 and the sphere 4525 are sequentially arranged in the blind hole 4521, and then the sphere 4525 is pushed by the elastic force of the elastic member 4523 to be engaged with the upper cylinder A first engaging portion 6503 or a second engaging portion 6505 on the inner peripheral wall of the body 650. The guiding member 443 may be a rod-shaped, spherical or other polygonal shape element. As long as the element has a first end 4431 and a second end 4433, it is the guiding piece 443 considered by the present invention.

In short, the dial 4541 can be moved between the two ends of the groove 6501, thereby changing the structure of the braking unit 144. As shown in FIGS. 3A and 3B, when the toggle member 4541 is located at a first end 65011 of the groove 6501, the guide member 443 abuts the low point 4501 of the slope 450, and the ball 4525 is engaged with the first engagement The portion 6503 maintains the guide 443 in a state where it does not protrude from the stopper 441. On the other hand, if the toggle member 4541 is controlled to move clockwise in FIG. 3B, so that when the toggle member 4541 is located at a second end 65013 of the groove 6501, the guide member 443 abuts against the slope 450 At the high point 4503, the sphere 4525 is engaged with the second engaging portion 6505, so that the guide 443 is maintained in a state protruding beyond the stopper 441.

As also shown in FIGS. 1, 2A, and 2B, the pivot shaft 481 continues to extend through the braking unit 144 in the axial direction in addition to the shaft hole portion 654. The three fixing screws 240 respectively pass through the three fixing holes 1420 formed on the cover 142 to connect the cover 142 to the pivot shaft 481. In this way, when the cover body 142 rotates, it will drive the adjusting member 485 to move axially relative to the fixing base 461. Please refer to FIG. 4 at the same time. On the other hand, the cover 142 further has a groove 1422 and a stopper 1424. When the guide 443 is kept protruding out of the limiter 441, the guide 443 The first end 4431 will enter the groove 1422, and the cover 142 will be restricted by the stop portion 1424 when rotating. Conversely, when the guide 443 is maintained in a state where it does not protrude beyond the limiter 441, the first end 4431 of the guide 443 will not enter the groove 1422, and the stopper 1424 will not restrict the cover The rotation of the body 142. The groove 1422 and the stop 1424 form a complete ring.

Before the assembled sight 10 is corrected, the sight 10 needs to be set to zero. When the sight 10 completes the zero setting, the guide 443 will keep protruding out of the limiter 441, and then the stop portion 1424 on the cover 142 will abut the first end 4431 of the guide 443 (As shown in Figure 4), set the position of the cover 142 to the zero setting (that is, the starting position of the spring correction). After determining the position of the cover 142 at the zero setting, turn the dial 454 to switch the second end 4433 of the guide 443 to abut the low point 4501 of the slope 450, at the first end 4431 of the guide 443 After fully retracting into the limit member 441, the correction of the impact can be performed.

It is worth noting that when the sight 10 is to return to the zero setting, it is necessary to turn the dial 454 first to switch the second end 4433 of the guide 443 to abut the high point 4503 of the slope 450 to make the guide The first end 4431 of the piece 443 protrudes from the limiting piece 441 and enters the groove 1422. After the first end 4431 of the guide 443 enters the groove 1422, the cover 142 is rotated in the reverse direction until the stop 1424 and the first end 4431 of the guide 443 abut against each other and cannot rotate any more. The cover 142 returns to the position of the zero setting (that is, the sight 10 is adjusted back to the zero setting).

In short, since the sight 10 of the present invention is provided with a brake unit 144 with a switchable structure, the sight 10 has a function of quickly returning to zero in addition to the function of normal spring correction. When the guide 443 is not convex, the sight 10 can perform the correction of the spring. When the guide 443 is raised, as long as the adjustment mechanism 14 is operated in the reverse direction until it can no longer rotate, the sight 10 returns to the original zero setting, and the user does not need to spend extra time to re-point the sight 10 Perform another zero setting.
