Description

Technical Field

[0001] The utility model belongs to the technical field of sight structure design, and particularly relates to a fixing and locking device for a sight. Background Art

[0002] Infrared sights use infrared light to create images and can be categorized as either active or passive. Active infrared sights emit infrared light, then use the infrared light reflected from the target to create an infrared image of the target, which is then converted into a visible light image. This allows targeting at night. Passive infrared sights use infrared light emitted or reflected by the target itself to create an infrared image of the target, providing greater concealment.

[0003] Chinese utility model patent CN218097412U discloses an infrared sight with a locking function, comprising an infrared sight body, a password input panel installed on the left side of the front end of the infrared sight body, an imaging adjustment button installed on the right side of the front end of the infrared sight body, the top of the infrared sight body being electrically connected to an infrared emitter via a wire, the bottom of the infrared sight body being fixedly connected to two shells, and the interiors of the two shells being provided with a locking device. Through the cooperation between the handwheel, the double-threaded rod, the nut and the fixed block, the user rotates the handwheel to cause the handwheel to rotate the double-threaded rod. Since the threads on both sides of the double-threaded rod are in opposite directions, the two nuts move toward the middle at the same time. The nuts move under the restriction of the slider and drive the fixed block to move. The two fixed blocks will be clamped at the interface of the firearm, so that the infrared sight body can be connected to the interfaces of different models of firearms, thereby improving the applicability of this infrared sight with a locking function.

[0004] In order to fix and lock the infrared sight on the firearm, the above-mentioned infrared sight with a locking function is equipped with structures such as a handwheel, a double-headed threaded rod, a nut and a fixing block. However, the above-mentioned infrared sight with a locking function does not have the function of protecting the handwheel. Since the handwheel is always exposed to the external environment, if people or objects in the external environment collide with the handwheel, it is easy to cause the handwheel to rotate accidentally and cause the fixed locking structure of the infrared sight body to loosen, thereby affecting the stability of the connection between the infrared sight and the firearm. Utility Model Content

[0005] The utility model provides a fixing and locking device for a sighting scope to solve the problems in the background technology.

By providing a butterfly bolt 3, the butterfly bolt 3 is rotated and displaced by twisting it. When one end of the butterfly bolt 3 is inserted into the socket on the outer shell 2, the handwheel 202 and the bidirectional screw rod 201 can be locked, so that the bidirectional screw rod 201 is not prone to accidental rotation, thereby enhancing the stability of the fixed locking structure.

[0024] See also Figures 1 to 3 As shown, a nut seat 203 is movably provided on both sides of the bidirectional screw rod 201. The nut seat 203 is threadedly connected to the bidirectional screw rod 201, and a fixing block 204 is fixedly provided at the bottom of the nut seat 203. By providing the bidirectional screw rod 201, the nut seat 203 and the fixing block 204, the bidirectional screw rod 201 is driven to rotate by turning the hand wheel 202. The rotating bidirectional screw rod 201 then drives the fixing blocks 204 on both sides to move through the nut seat 203. When the two fixing blocks 204 are clamped at the interface of the firearm, the infrared sight body 1 can be fixed and locked on the firearm. A guide block 205 is fixedly provided on the top of the nut seat 203. A guide rod 206 is movably provided on the inner wall of the guide block 205.

[0025] See also Figures 1 to 3 As shown, the butterfly bolt 3 is movably connected to the housing 2. By tightening the butterfly bolt 3, the butterfly bolt 3 is rotated. When one end of the butterfly bolt 3 is removed from the socket in the housing 2, the handwheel 202 and the bidirectional screw 201 are unlocked. Side panels 4 are fixedly mounted on both sides of the housing 2. These side panels 4 are movably connected to the infrared sight body 1 via second bolts 401. Threaded holes corresponding to the second bolts 401 are provided on both sides of the bottom of the infrared sight body 1. By tightening the second bolts 401, the second bolts 401 are rotated. When one end of the second bolt 401 is removed from the threaded hole in the infrared sight body 1, the housing 2 can be removed. An access door 6 is movably installed on the front of the housing 2 via screws. By loosening the screws, the access door 6 can be removed from the housing 2, providing convenient access to the components within the housing 2.

[0026] When in use, the bidirectional screw rod 201 is rotated by turning the hand wheel 202, and the rotating bidirectional screw rod 201 then drives the fixing blocks 204 on both sides to move through the nut seat 203. When the two fixing blocks 204 are clamped at the interface of the firearm, the infrared sight body 1 can be fixed and locked on the firearm;

[0027] When locking the bidirectional screw rod 201, the butterfly bolt 3 is rotated and displaced by twisting it. When one end of the butterfly bolt 3 is inserted into the socket on the housing 2, the hand wheel 202 and the bidirectional screw rod 201 can be locked. When protecting the hand wheel 202, the protective cover 501 is threadedly installed on the threaded ring 5. The protective cover 501 can cover the hand wheel 202, so that the hand wheel 202 is in the independent and closed space.

[0028] When unlocking the bidirectional screw rod 201, the butterfly bolt 3 is rotated and displaced by twisting the butterfly bolt 3. When one end of the butterfly bolt 3 is removed from the socket on the housing 2, the hand wheel 202 and the bidirectional screw rod 201 can be unlocked.

[0029] When disassembling the outer shell 2, the second bolt 401 can be rotated and displaced by screwing the second bolt 401. When one end of the second bolt 401 comes out of the threaded hole on the infrared sight body 1, the outer shell 2 can be disassembled. When disassembling the inspection door 6, loosen the screws and then remove the inspection door 6 on the outer shell 2, thereby facilitating the maintenance of the parts inside the outer shell 2.
