The compensation mechanism 10 according to one embodiment of the present invention includes an adjustment cover 11 , an adjustment unit 12 , a base 13 , a stop unit 14 and an adjustment screw 15 . Wherein, the user rotates the adjustment cover 11 in a preset direction to perform bounce compensation for a sight (not shown). On the other hand, the user only needs to turn the adjustment cover 11 in the opposite direction to the preset direction until the adjustment cover 11 is stopped by the stop unit 14 , and then the compensation mechanism 10 can be adjusted back to the state when it is set to zero. The assembly of these components is detailed below:

The base 13 is fixed on the body of the sight. As shown in Figure 1, the base 13 includes a base body cover 131, a first base body 132 and a second base body 133, wherein the second base body 133 is arranged on the body of the sight, and the first base body 132 is disposed on the second base body 133 , and the base body cover 131 is disposed on an end of the first base body 132 away from the second base body 133 . As shown in FIG. 2 , the base cover 131 has a first central hole 311 , the first base 132 has a second central hole 321 , and the second base 133 has a third central hole 331 . The adjustment unit 12 is disposed on the base 13 by passing through the first center hole 311 and the second center hole 321 , and can rotate relative to the base 13 . Specifically, the adjustment unit 12 includes a center column upper cover 121 and a center column 122, wherein the center column 122 is rotatably arranged between the first seat body 132 and the second seat body 133, and the center column upper cover 121 is It is disposed on an end of the central column 122 away from the second base 133 .

In addition, the center column 122 has an adjustment hole 221 (as shown in FIG. 1 ), and the adjustment screw 15 is arranged in the adjustment hole 221, and passes through the second seat body 133 through the third center hole 331 to extend to the aiming hole 331. inside the body of the device. It should be noted that the outer peripheral wall of the adjustment screw 15 has an external thread (not shown), and the inner peripheral wall of the adjustment hole 221 has an internal thread (not shown), and the external thread and the internal thread can cooperate with each other. . If so set, when relative rotation occurs between the adjustment screw 15 and the center column 122, there will also be a compensation mechanism between the adjustment screw 15 and the center column 122. The axis of 10 moves upwards relative to each other. Moreover, as shown in FIG. 2 , the cross-sectional shape of the third center hole 331 of the second seat body 133 corresponds to the cross-sectional shape of the adjusting screw 15 . If set in this way, when the base 13 is fixed, the adjustment screw 15 will not rotate relative to the base 13 . Therefore, when the central column 122 of the adjusting unit 12 rotates relative to the base 13 , the adjusting screw 15 will only move axially relative to the base 13 . In addition, when the adjustment unit 12 rotates relative to the base 13 , the central column 122 cannot move axially relative to the base 13 because the compensation mechanism 10 is limited by the base 13 in the axial direction. In another embodiment, the central column 122 of the adjusting unit 12 can rotate and move axially relative to the base 13 at the same time.

As shown in FIG. 1 , the stop unit 14 is disposed between the adjustment unit 12 and the base 13 , and includes a protrusion 141 and a turntable 142 , wherein the turntable 142 is sleeved on the center column 122 of the adjustment unit 12 , and the protruding portion 141 is disposed on the turntable 142 and extends through the upper cover 131 of the base 13 to protrude from the upper cover 131 of the base. It should be noted that an external thread (not shown) is formed on the outer peripheral wall of the central column 122 , and an internal thread (not shown) is formed on the inner peripheral wall of the turntable 142 , and the external thread and the internal thread can cooperate with each other. If so arranged, when the relative rotation occurs between the turntable 142 and the central column 122 , the relative movement between the turntable 142 and the central column 122 will also occur in the axial direction of the compensation mechanism 10 . In addition, two fixing screws 313 (as shown in FIG. 2 ) pass through the base cover 131 and the turntable 142 sequentially, and are fixed on the first base 132 of the base 13 . If so set, the turntable 142 will not be able to rotate relative to the base 13, therefore, when the central column 122 of the adjustment unit 12 rotates relative to the base 13, the turntable 142 and the protrusion 141 arranged thereon will only move relative to the base 13. Seat 13 moves axially. It is worth noting that by rotating the central column 122 , the protruding part 141 can be controlled to protrude or not protrude from the upper cover 131 of the base body.

In this embodiment, the protruding portion 141 includes a nut portion 411 , a flange portion 412 and a threaded portion 413 , and the turntable 142 has a screw hole 421 (as shown in FIG. 2 ). Wherein, the nut part 411 and the threaded part 413 are respectively connected to the two ends of the flange part 412, and the threaded part 413 is connected by The screw holes 421 are provided on the turntable 142 . It should be noted that the outer peripheral wall of the threaded part 413 has an external thread (not shown), and the inner peripheral wall of the screw hole 421 has an internal thread (not shown), and the external thread and the internal thread can cooperate with each other. . If so arranged, when the relative rotation occurs between the turntable 142 and the protruding part 141 , relative movement will also occur between the turntable 142 and the protruding part 141 in the axial direction of the compensation mechanism 10 . In this embodiment, the seat upper cover 131 has a through hole 312 (as shown in FIG. 2 ) that can accommodate the nut portion 411 , and the outer diameter of the flange portion 412 is larger than the outer diameter of the threaded portion 413 and the through hole 312. the inside diameter of. In this way, when the protruding portion 141 moves axially toward the base cover 131 , the nut portion 411 passes through the through hole 312 until the flange portion 412 abuts against the lower end of the base cover 131 to stop. Moreover, when the flange portion 412 abuts against the lower end of the base body upper cover 131 , the nut portion 411 will protrude from the upper end of the base body upper cover 131 .

As shown in FIG. 1, the adjustment cover 11 is fixed on the center column upper cover 121 of the adjustment unit 12 by a plurality of adjustment cover screws 111, so that the adjustment unit 12 can be driven to rotate relative to the base 13 when the adjustment cover 11 rotates. Please refer to FIG. 3 , the adjustment cover 11 has an annular groove 112 and a stop portion 113 on a side facing the base 13 , wherein the annular groove 112 and the stop portion 113 form a complete circle. When the flange portion 412 abuts against the lower end of the base body cover 131 , the protruding portion 141 not only protrudes from the base body cover 131 , but also enters into the annular groove 112 . In this way, the protruding portion 141 may contact the stop portion 113 , which will restrict the rotation of the adjustment cover 11 .

Before operating the compensating mechanism 10 to perform bounce compensation, a zero setting must be performed. In the process of zero reset, the adjustment screw 15 is adjusted to a reference position, and the protrusion 141 of the stop unit 14 is adjusted into the annular groove 112 of the adjustment cover 11 and at the same time abuts against the adjustment cover 11 The stopper 113. Specifically, the user can remove the adjustment cover 11 first, and manually rotate the adjustment unit 12 to axially move the adjustment screw 15 to the reference position. On the other hand, due to the rotation of the adjustment unit 12, the protrusion 141 and the rotating disk 142 will move axially relative to the base 13, As a result, the protrusion 141 may not enter into the annular groove 112 yet. At this time, the user can rotate the protruding part 141 to make the protruding part 141 move axially toward the upper cover 131 of the seat body relative to the turntable 142 until the flange part 412 abuts against the lower end of the upper cover 131 of the seat body and stops. The outer diameter of the flange portion 412 is larger than the outer diameter of the threaded portion 413 and the inner diameter of the through hole 312 , so that the protrusion 141 will not fall or come off when the user rotates the protrusion 141 . Finally, the user can adjust the stop portion 113 of the adjustment cover 11 to abut against the protruding portion 141 , and fix the adjustment cover 11 to the adjustment unit 12 to complete the zero setting. Wherein, when the protruding portion 141 is adjusted into the annular groove 112 and abuts against the stop portion 113 at the same time, the adjustment cover 11 is at a zero position.

After completing the zero reset setting, the user can operate the compensation mechanism 10 to perform impact compensation. It can be understood that the adjustment cover 11 can only rotate in a predetermined direction (for example, counterclockwise) initially because it is limited by the stop unit 14, and once the adjustment cover 11 rotates in the predetermined direction, the protrusion 141 It will leave the stop portion 113 , and then release the restriction of the stop unit 14 on the adjustment cover 11 (in other words, the adjustment cover 11 is not limited to only rotate in the preset direction). During bounce compensation, the rotation of the adjustment cover 11 will drive the adjustment unit 12 to rotate relative to the base 13 , and at the same time drive the adjustment screw 15 to move axially relative to the base 13 until the adjustment screw 15 moves to a preset position and stops. On the other hand, during the rotation of the adjustment unit 12 , the protrusion 141 and the turntable 142 will move axially relative to the base 13 in a direction away from the base cover 131 , causing the protrusion 141 to leave the annular groove 112 .

It should be noted that, during the above impact compensation process, the user can reset the compensation mechanism 10 to the zero setting at any time. Specifically, the user can rotate the adjustment cover 11 in a direction opposite to the preset direction (for example, clockwise), so as to drive the adjustment unit 12 to rotate, and then move the adjustment screw 15 axially away from the preset position. On the other hand, during the rotation of the adjusting unit 12 , the protruding portion 141 and the turntable 142 will axially move relative to the base 13 toward the upper cover 131 of the base until the flange portion 412 abuts against the upper cover 131 of the base. and stop at the lower end. at the same time, The protrusion 141 enters into the annular groove 112 again. Finally, when the stop portion 113 of the adjustment cover 11 abuts against the protruding portion 141 again, the adjustment cover 11 is limited by the stop unit 14 and stops at the zero position (in other words, the adjustment cover 11 cannot go further to the preset position). Rotate in the opposite direction of the direction), and the whole screw 15 also returns to the reference position, so that the compensation mechanism 10 is returned to the zero setting.

By the action of the stop unit 14, as long as the adjustment cover 11 is turned in the opposite direction of the operation direction, the compensation mechanism 10 of the present invention can quickly return to the zero setting. For users, the design and operation of the compensating mechanism 10 are more intuitive.
