Description

Technical Field

[0001] The invention relates to the technical field of sniper rifle auxiliary devices, and in particular to a plug-and-pull locking type zero stop structure with a circle number indication function. Background Art

[0002] In actual combat, snipers need to frequently adjust the scope to capture the target's position. In actual operation, the aiming adjustment is usually performed after the sight is reset to zero. Currently, most people check the zero scale with their eyes and then turn the adjustment handwheel to reset to zero. This process is cumbersome and time-consuming. In addition, the adjustment range of the current aiming structure is one circle, which cannot meet the needs of a larger range of adjustment. Secondly, after the aiming position is adjusted, it is easy to cause the aiming position to shift due to inadvertent external force on the adjustment handwheel. When it is used again, it needs to be readjusted, which is cumbersome.

[0003] Therefore, there is an urgent need for a plug-and-lock zero stop structure with a circle number indication function to solve the problem that the zero position adjustment of the existing sniper rifle aiming structure is relatively cumbersome and the adjustment range is relatively small. Summary of the invention

[0004] The invention provides a plug-in locking type zero stop structure with a circle number indication function, which solves the problem that the zero position adjustment of the existing sniper rifle aiming structure is relatively complicated and the adjustment range is relatively small.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A plug-in and lock-type zero-position stop structure with a turn number indication function, comprising:

[0007] A connecting assembly, the connecting assembly comprising an adjusting screw, a slotted nut and a connecting shaft; a limiting block is provided at the end of the adjusting screw, the slotted nut is provided with a limiting groove matched with the limiting block, and the connecting shaft is fixed on the slotted nut;

[0008] A zero stop assembly, the zero stop assembly comprising a first limit pin, a second limit pin, a zero stop ring and a zero stop gear ring, the first limit pin, the second limit pin, the zero stop ring and the zero stop gear ring are all coaxially arranged with the adjusting screw; the zero stop ring and the zero stop gear ring can rotate relative to each other, the first limit pin is fixed on the tube body of the sighting scope, the second limit pin is fixed on the zero stop gear ring, and the zero stop ring is provided with a first arc slide and a second arc slide; the free end of the first limit pin is in the first arc slide, and the free end of the second limit pin is in the second arc slide;

[0009] An adjusting hand wheel, wherein the inner wall of the adjusting hand wheel is provided with internal teeth meshing with the outer teeth of the zero position stop gear ring.

[0010] Furthermore, the toothed pressure ring is fixedly arranged on the connecting shaft, a movable gear ring is movably arranged at the end of the connecting shaft, and the inner teeth of the adjusting hand wheel can be meshed with the outer teeth of the toothed pressure ring and the movable gear ring.

[0011] Furthermore, a cylindrical receiving groove is provided on the connecting shaft, a cylindrical spring and a stepping pin are placed in the cylindrical receiving groove, and one end of the stepping pin away from the cylindrical spring can abut against the inner wall of the slotted nut.

[0012] Furthermore, the adjusting hand wheel can move along the axial direction of the connecting shaft, the cross section of the movable gear ring along the axial direction is T-shaped, and a limiting screw is arranged on the adjusting hand wheel.

[0013] Furthermore, the first curved slideway and the second curved slideway have the same structure and are arranged in a mirror-symmetrical manner.

[0014] Furthermore, the outer walls of the connecting shaft and the toothed pressure ring are both provided with an annular receiving groove, and an annular sealing ring is placed in the annular receiving groove.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] In actual use, the first limiting pin is fixedly arranged on the mirror tube and is at the zero position and the end of the first arc-shaped slideway, and the second limiting pin is at the zero position and at the end of the second arc-shaped slideway.

[0017] First, after the adjusting hand wheel rotates a certain arc, it rotates in the opposite direction, and under the blockage of the first limit pin, the adjusting hand wheel quickly returns to the zero position;

[0018] Secondly, when the adjusting hand wheel rotates, the inner teeth drive the zero stop gear ring to rotate together. When the adjusting hand wheel rotates more than one circle, the first limit pin fixed on the zero stop gear ring drives the zero stop circle below to rotate together. The upper and lower surfaces of the zero stop circle have a first arc slideway and a second arc slideway for the first pin and the second pin to slide. The zero stop gear ring and the zero stop circle can rotate one circle respectively. After the zero stop circle rotates to the end, it is blocked by the first limit pin and cannot rotate any further. Therefore, it can rotate two circles, thereby achieving the purpose of increasing the adjustment range.

[0019] In addition, the zero stop circle will only rotate during the second circle, thus indicating which circle it is. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] This embodiment provides a plug-in locking zero stop structure with a turn indication function, such as Figure 1-Figure 11 As shown, including:

[0036] The connecting assembly comprises an adjusting screw 1, a slotted nut 2 and a connecting shaft 3; a limiting block 4 is arranged at the end of the adjusting screw 1, the slotted nut 2 is provided with a limiting groove 5 matched with the limiting block 4, and the connecting shaft 3 is fixed on the slotted nut 2;

[0037] The zero stop assembly includes a first limit pin 6, a second limit pin 7, a zero stop ring 8 and a zero stop gear ring 9. The first limit pin 6, the second limit pin 7, the zero stop ring 8 and the zero stop gear ring 9 are all coaxially arranged with the adjusting screw 1; the zero stop ring 8 and the zero stop gear ring 9 can rotate relative to each other, the first limit pin 6 is fixed on the tube body of the sight, the second limit pin 7 is fixed on the zero stop gear ring 8, and the zero stop ring 8 is provided with a first arc slide 10 and a second arc slide 11; the free end of the first limit pin 6 is in the first arc slide 10, and the free end of the second limit pin 7 is in the second arc slide 11; the structures of the first arc slide 10 and the second arc slide 11 are the same and are arranged in a mirror-symmetrical manner.

[0038] The adjusting hand wheel 12 has internal teeth on its inner wall which mesh with the external teeth of the zero position stop gear ring 9.

[0039] In actual use, the first limiting nail 6 is fixedly arranged on the mirror tube and is at the zero position and the end of the first arc-shaped slideway 10 , and the second limiting nail 7 is at the zero position and at the end of the second arc-shaped slideway 11 .

[0040] First, after the adjusting hand wheel 12 rotates a certain arc, it rotates in the opposite direction, and under the obstruction of the first limit pin 6, the adjusting hand wheel 12 quickly returns to the zero position;

[0041] Secondly, when the adjusting hand wheel 12 rotates, the inner teeth drive the zero stop gear ring 9 to rotate together. When the adjusting hand wheel 12 rotates more than one circle, the first limit pin 6 fixed on the zero stop gear ring 9 drives the zero stop circle 8 below to rotate together. The upper and lower surfaces of the zero stop circle 8 have a first arc slide 10 and a second arc slide 11 for the first pin 6 and the second pin 7 to slide. The zero stop gear ring 9 and the zero stop circle 8 can each rotate one circle. After the zero stop circle 8 rotates to the end, it is blocked by the first limit pin 6 and cannot rotate any further, so it can rotate two circles, thereby achieving the purpose of increasing the adjustment range.

[0042] In addition, the zero stop circle 8 will only rotate during the second circle, thereby indicating which circle it is.

[0043] The above embodiment is further optimized, the toothed pressure ring 13 is fixedly arranged on the connecting shaft 3, the end of the connecting shaft 3 is movably provided with a movable gear ring 14, the inner teeth of the adjusting hand wheel 12 can be meshed with the outer teeth of the toothed pressure ring 13 and the movable gear ring 14, the adjusting hand wheel 12 can move along the axial direction of the connecting shaft 3, the cross section of the movable gear ring 14 along the axial direction is T-shaped, and a limit screw 19 is provided on the adjusting hand wheel 12. Among them, the inner wall of the adjusting hand wheel 12 is provided with three groups of inner teeth, the three groups of inner teeth are arranged at intervals, and the three groups of inner teeth can be meshed with the zero stop gear ring 9, the toothed pressure ring 13 and the movable gear ring 14 respectively. There are three limit screws, which are circumferentially distributed on the adjusting hand wheel, the limit screws are connected to the adjusting hand wheel by threads, and one end of the limit screw extending into the adjusting hand wheel is below the movable gear ring; under the obstruction of the limit screw, when the adjusting hand wheel is lifted, it will not slide out.

[0044] In the locked state, the inner teeth in the middle of the inner wall of the adjusting hand wheel 12 and the outer teeth of the toothed pressure ring 13 interact with each other, and the adjusting hand wheel cannot be rotated to achieve locking. The adjusting hand wheel 12 is lifted up to enter the working state, and the innermost inner teeth of the adjusting hand wheel 12 and the outer teeth of the movable gear ring 14 interact with each other to achieve rotation. In the locked state, even if an external force acts on the adjusting hand wheel 12, the adjusting hand wheel 12 will not rotate, so that the adjusted aiming position will not be changed due to external force during the movement, thereby avoiding the time waste caused by readjustment.

[0045] The above embodiment is further optimized, in which a cylindrical receiving groove 15 is provided on the connecting shaft 3, in which a cylindrical spring 16 and a stepping pin 18 are placed, and one end of the stepping pin 18 away from the cylindrical spring 16 can abut against the inner wall of the slotted nut 2.

[0046] The above embodiment is further optimized, the outer walls of the connecting shaft 3 and the toothed pressure ring 13 are both provided with an annular receiving groove 20, and an annular sealing ring 21 is placed in the annular receiving groove 20. The provision of the annular sealing ring 21 can improve the overall sealing performance.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
