Description

Technical Field

[0001] The utility model relates to the technical field of firearm equipment, and particularly relates to a firearm aiming assembly. Background Art

[0002] When a sniper rifle is fired, the user will accurately aim at the enemy through the aiming device thereon. At present, most of the structures for the zero-position stop of the turret on the sniper rifle aiming device are pin-fixed structures, which can only limit one circle and cannot meet the needs when there is a greater range adjustment requirement; in addition, the pin itself will occupy a certain adjustment range, which is not conducive to the user's timely adjustment.

[0003] Therefore, there is an urgent need for a firearm aiming assembly at present to solve the problems of small adjustment range of the turret used on the existing sniper rifle and complex zero-position stop structure of the turret. Summary of the Utility Model

[0004] The utility model provides a firearm aiming assembly to solve the problems of small adjustment range of the turret used on the existing sniper rifle and complex zero-position stop structure of the turret.

[0005] In order to achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A firearm aiming assembly, comprising:

[0007] A connecting shaft, on which a cylindrical gear is arranged;

[0008] An adjusting handwheel, which has a cylindrical cavity, and the side wall of the cylindrical cavity is provided with a tooth groove for cooperating with the cylindrical gear;

[0009] A limiting retaining ring, which is arranged on the connecting shaft;

[0010] A zero-stop mechanism, which includes a limiting pin and a cylindrical limiting block with a clamping groove. The cylindrical limiting block is rotatably arranged on the end face of the adjusting handwheel, the length direction of the clamping groove is arranged at an angle with the radial direction of the cylindrical limiting block, and the limiting pin is fixedly arranged on the limiting retaining ring.

[0011] Furthermore, it further includes a pressing screw, and one end of the connecting shaft is provided with a threaded hole for cooperating with the pressing screw.

[0012] Furthermore, an anti-loosening sealing ring is arranged between the adjusting handwheel and the pressing screw.

[0013] To sum up, due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows:

[0014] In actual use, when the rotation adjustment handwheel is rotated one full turn and the card slot on the cylindrical limit block engages with the limit pin, one full turn of adjustment is completed. Since the limit block is rotatably arranged in the adjustment handwheel, when an external force is continuously applied to rotate the adjustment handwheel, after the cylindrical limit block rotates a certain angle, the card slot of the cylindrical limit block will disengage from the limit pin and continue to rotate, thus realizing two turns of adjustment. The adjustment range of the present utility model is larger and the operation is simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will describe the present utility model in detail with reference to the drawings.

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] In this embodiment, a gun sighting assembly is provided, as Figures 1 - 5 shown, including:

[0025] a connecting shaft 1, on which a cylindrical gear 2 is provided;

[0026] an adjustment handwheel 3, which has a cylindrical cavity, and the side wall of the cylindrical cavity is provided with a tooth groove 4 that cooperates with the cylindrical gear 2;

[0027] a limit retaining ring 5, which is arranged on the connecting shaft 1;

[0028] Zero-stop mechanism, the zero-stop mechanism includes a limit pin 7 and a cylindrical limit block 6 with a card slot 8. The cylindrical limit block 6 is rotatably arranged on the end face of the adjusting handwheel 3. The length direction of the card slot 8 is arranged at an angle to the radial direction of the cylindrical limit block 6. The limit pin 7 is fixedly arranged on the limit retaining ring 5.

[0029] In actual use, when the adjusting handwheel 3 is rotated one circle so that the card slot 8 on the cylindrical limit block 6 is engaged with the limit pin 7, one circle of adjustment is completed. Since the limit block 6 is rotatably arranged in the adjusting handwheel 3, and then an external force is continuously applied to rotate the adjusting handwheel 3. After the cylindrical limit block 6 rotates a certain angle, the card slot 8 of the cylindrical limit block 6 will disengage from the limit pin 7 and continue to rotate, thereby realizing two circles of adjustment. The adjustment range of the utility model is larger and the operation is simpler.

[0030] Further optimizing the above embodiment, it further includes a compression screw 9. One end of the connecting shaft 1 is provided with a threaded hole for cooperating with the compression screw 9. Among them, the setting of the compression screw 9 can limit the adjusting handwheel 3 from sliding out of the connecting shaft 1 and is also convenient for disassembly and maintenance.

[0031] Further optimizing the above embodiment, an anti-loosening sealing ring 10 is arranged between the adjusting handwheel 3 and the compression screw 9. The setting of the anti-loosening sealing ring 10 makes the connection part more firm.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
