Specifically, the locking piece 3 is detachably connected to the adjusting hand wheel 4 and the adjusting pin 2, and the locking piece 3 can be a screw or a jack. When the locking piece 3 is tightened, the adjusting hand wheel 4 is fixedly connected to the adjusting pin 2, and the two can rotate synchronously; when the locking piece 3 is loosened, the adjusting hand wheel 4 and the adjusting pin 2 can rotate relative to each other.

[0029] The adjusting seat 1 is threadedly connected to the second end of the adjusting pin 2, the indicating ring 5 is fixedly connected to the adjusting seat 1 and is arranged on the inner side of the adjusting hand wheel 4, the outer peripheral wall of the adjusting hand wheel 4 is provided with a scale, the outer peripheral wall of the indicating ring 5 is provided with an indicating line, and the indicating line is arranged in correspondence with the scale. The adjusting hand wheel 4 can drive the adjusting pin 2 to rotate relative to the adjusting seat 1 and the indicating ring 5 about the axis of the adjusting pin 2, so that the adjusting pin 2 moves up and down relative to the adjusting seat 1 in the axial direction to adjust the height or the left-right position of the internal dividing plate of the mirror body.

[0030] The middle part of the adjusting pin 2 is provided with a convex boss part 21 protruding outward, and the convex boss part 21 extends along the circumference of the adjusting pin 2. The adjusting seat 1 is provided with an annular accommodating groove 11, and the accommodating groove 11 is provided with a groove opening upward, and the convex boss part 21 is arranged in the accommodating groove 11.

[0031] The stop ring 6 is movably sleeved on the middle part of the adjusting pin 2, and the stop ring 6 is arranged above the convex boss part 21 and the groove wall of the accommodating groove 11, and the adjusting pin 2 can rotate relative to the stop ring 6.

[0032] The upper side of the stop ring 6 is provided with a spiral groove 61 and a self-locking groove 62. The spiral groove 61 extends spirally from inside to outside, and preferably extends clockwise; the inner end of the spiral groove 61 is provided with a closed end 611, and the outer end of the spiral groove 61 is provided with an open end. The self-locking groove 62 extends along the radial direction of the stop ring 6, the first end of the self-locking groove 62 communicates with the open end, and the second end of the self-locking groove 62 penetrates through the peripheral wall of the stop ring 6, so that the zero reset vertical pin 7 can be embedded in the spiral groove 61. The two side groove walls of the self-locking groove 62 can limit the rotational movement of the zero reset vertical pin 7, that is, when the zero reset vertical pin 7 moves into the self-locking groove 62, the self-locking groove 62 can limit the forward and reverse rotation of the zero reset vertical pin 7 and the adjusting hand wheel 4.

[0033] The zero reset vertical pin 7 is arranged on the inner side of the adjusting hand wheel 4, the first end of the zero reset vertical pin 7 is connected with the side top piece 8, and the second end of the zero reset vertical pin 7 is arranged in the spiral groove 61 and can move along the extension direction of the spiral groove 61 and can enter and exit the self-locking groove 62.

[0034] The first sliding groove 41 is radially formed in the adjusting hand wheel 4 and penetrates the outer peripheral wall of the adjusting hand wheel 4.

When the zero-reset vertical pin 7 moves to the open end of the helical groove 61, the side top piece 8 can drive the zero-reset vertical pin 7 to move into the self-locking groove 62 under the action of the first elastic piece 9.

[0035] After the adjuster is calibrated to zero by shooting, the locking member 3 is loosened so that the adjusting hand wheel 4 can rotate relative to the adjusting pin 2. Thereafter, the adjusting pin 2 is fixed, and the adjusting hand wheel 4 can rotate together with the side top piece 8 and the zero-reset vertical pin 7. In this process, the zero-reset vertical pin 7 moves along the extension direction of the helical groove 61, thereby driving the zero-reset vertical pin 7 and the side top piece 8 to move along the extension direction of the first sliding groove 41, so that the zero-reset vertical pin 7 enters the self-locking groove 62. At this time, the adjusting hand wheel 4 is in a self-locking position. Then, the locking member 3 can be tightened to fix the adjusting hand wheel 4 and the adjusting pin 2. Since the adjusting pin 2 is at the zero-reset position and the adjusting hand wheel 4 is at the self-locking position, the entire adjuster is in a zero-reset self-locking state, which can effectively avoid the situation that the calibration of the adjuster is invalid due to accidental touch.

The outer peripheral wall of the stop ring 6 is provided with an external thread structure (not shown in the figure), which is matched and connected with the internal thread structure, so as to facilitate the fixed connection of the stop ring 6 and the adjusting seat 1 together.

[0040] In combination Figure 2 and Figure 3 The boss portion 21 of the adjusting pin 2 is provided with two second sliding grooves 211 along the radial direction thereof, and the two second sliding grooves 211 are symmetrically arranged with the axis of the adjusting pin 2 as the axis of symmetry.

[0041] The side ejection locking type zero return adjuster further comprises a gear ring 20, two adjusting marbles 30 and two second elastic members 40. The gear ring 20 is sleeved on the outer side of the boss portion 21 and arranged in the accommodating groove 11, and the inner peripheral wall of the gear ring 20 is provided with a plurality of teeth. The adjusting marble 30 is movably arranged in the second sliding groove 211, and the adjusting marble 30 comprises a shell and a wave bead arranged on the end portion of the shell. The second elastic member 40 is elastically abutted between the adjusting marble 30 and the second sliding groove 211, and the second elastic member 40 is preferably a compression spring, so as to exert an outward force on the adjusting marble 30, so that the adjusting marble 30 can move back and forth along the extension direction of the second sliding groove 211, and the wave bead of the adjusting marble 30 can protrude out of the second sliding groove 211 and be matched and connected with the gear ring 20.

[0042] In Figure 2 , the side ejection locking type zero return adjuster further comprises a moving adjusting pin 50, and the moving adjusting pin 50 comprises a connecting head portion and a protruding portion.

[0043] The lower portion of the adjusting pin 2 is provided with an installation groove 22 in the axial direction, and the bottom wall of the adjusting seat 1 is provided with an installation hole 13 coaxially arranged and communicated with the installation groove 22. The moving adjusting pin 50 is arranged in the installation groove 22, the connecting head portion is threadedly connected with the installation groove 22, and the protruding portion extends downward through the installation hole 13 and is used for extending into the scope body.

[0044] The scope embodiment:

[0045] The scope provided by the embodiment comprises a scope body and the side ejection locking type zero return adjuster of the above-mentioned embodiment, and the side ejection locking type zero return adjuster is connected on the scope body.

[0046] The zero position calibration process of the embodiment is as follows:

[0047] When the scope is mounted on the gun, and when calibrating the zero position, first turn the adjusting hand wheel 4 counterclockwise to drive the adjusting pin 2 to rotate, and calibrate the zero position at 100 meters by shooting. At this time, the adjusting pin 2 is in the zero position; then loosen the locking piece 3, and the adjusting hand wheel 4 can rotate relative to the adjusting pin 2; then, turn the adjusting hand wheel 4 clockwise to drive the zeroing vertical pin 7 and the side top piece 8 to move until the zeroing vertical pin 7 moves to the self-locking groove 62, at which time the side top piece 8 is completely ejected and the adjusting hand wheel 4 is in the self-locking position; then, tighten the locking piece 3 so that the regulator is in the zero position locked state to avoid accidental touch; when unlocking is required, the user can press the side top piece 8 inward to push the zeroing vertical pin 7 into the spiral groove 61. After that, the adjusting hand wheel 4 can be rotated counterclockwise, and with each rotation, the side top piece 8 retracts inward by a preset distance. The number of rotations of the adjusting hand wheel 4 can be known by the retraction distance of the side top piece 8.

[0048] In summary, it can be seen that the utility model provides a spiral groove so that the zeroing vertical pin can move along the extension direction of the spiral groove as the adjusting handwheel rotates, thereby driving the side top piece to move radially; after zeroing through shooting calibration, the adjusting pin is disconnected from the adjusting handwheel, and the adjusting handwheel is turned until the zeroing vertical pin is screwed into the self-locking groove. The self-locking groove can limit the forward and reverse rotation of the zeroing vertical pin. At this time, the adjusting pin and the adjusting handwheel are locked again to realize the zeroing self-locking function of the regulator. During this process, the user does not need to observe the scale line of the indicator ring with the naked eye, nor will he turn it one more turn. It has the advantages of easy operation and high proofreading accuracy.

[0049] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications.
