Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a lens protection device for a law enforcement recorder, comprising a law enforcement recorder 1, a transparent protective cover 2 is hingedly connected to the front side of the law enforcement recorder 1 by a hinge, a card slot 3 is opened on the right side of the transparent protective cover 2, a card plate 4 is arranged inside the card slot 3, a mounting box 5 is sleeved on the right side of the surface of the card plate 4, the rear side of the mounting box 5 is fixedly connected to the front side of the law enforcement recorder 1, the card plate 4 is rotatably connected to the inside of the mounting box 5 by a pin shaft, a worm gear 6 is fixedly connected to the front side of the card plate 4, a worm 7 is meshed with the left side of the worm gear 6, the top of the worm 7 passes through the top of the mounting box 5, and an anti-loosening mechanism 8 is fixedly connected to the bottom of the surface of the worm 7.

[0023] refer to Figure 5 The anti-loosening mechanism 8 includes a positioning gear 81, which is fixedly connected to the bottom of the surface of the worm 7. A positioning tooth plate 82 is meshed on the right side of the surface of the positioning gear 81. The right side of the positioning tooth plate 82 extends to the right side of the installation box 5. A push block 83 is fixedly connected to the right side of the positioning tooth plate 82, and the surface of the push block 83 contacts the surface of the installation box 5.

[0024] As a technical optimization solution of the utility model, by providing an anti-loosening mechanism 8, the worm 7 and the card plate 4 can be positioned to prevent the worm 7 from loosening and causing the card plate 4 to rotate erroneously, thereby improving the protectiveness of the transparent protective cover 2.

[0025] refer to Figure 5 A slide bar 9 is disposed inside the positioning tooth plate 82 , and the top of the slide bar 9 is fixedly connected to the inner wall of the installation box 5 through a connecting block.

[0026] As a technical optimization solution of the utility model, by setting the sliding rod 9, the sliding of the positioning tooth plate 82 can be stabilized to avoid shaking of the positioning tooth plate 82 during sliding movement, which causes the positioning tooth plate 82 to loosen, thereby improving the sliding stability of the positioning tooth plate 82.

[0027] refer to Figure 5 A spring 10 is fixedly connected to the surface of the slide rod 9 , and the bottom of the spring 10 is fixedly connected to the top of the positioning tooth plate 82 .

[0028] As a technical optimization solution of the utility model, by setting the spring 10, the positioning tooth plate 82 can be pulled to automatically reset and move, avoiding the positioning tooth plate 82 being unable to automatically return to its original position after being pushed and requiring manual reset, thereby improving the convenience of using the positioning tooth plate 82.

[0029] refer to Figure 5 The top of the positioning tooth plate 82 is fixedly connected with a shielding cloth 11 , and the top of the shielding cloth 11 is fixedly connected to the inner wall of the installation box 5 .

[0030] As a technical optimization solution of the utility model, by setting a shielding cloth 11, the interior of the installation box 5 can be shielded to prevent foreign matter from entering the interior of the installation box 5, prevent the positioning tooth plate 82 and the positioning gear 81 from being stuck, and improve the coordination efficiency of the positioning tooth plate 82 and the positioning gear 81.

[0031] refer to Figure 4 A torsion block 12 is fixedly connected to the top of the surface of the worm 7 , and the torsion block 12 is located at the top of the mounting box 5 .

[0032] As a technical optimization solution of the utility model, by providing the twist block 12, it is possible to facilitate the user to rotate the worm 7, thereby preventing the worm 7 from being difficult to be pinched by the user, resulting in difficulty in rotating the worm 7, and improving the rotation efficiency of the worm 7.

[0033] refer to Figure 4 The surface of the torsion block 12 is fixedly connected with a friction strip 13 , and the number of the friction strips 13 is several, and the several friction strips 13 are distributed at equal distances.

[0034] As a technical optimization solution of the utility model, by setting the friction strip 13, the friction between the twist block 12 and the user can be increased, avoiding the small friction between the twist block 12 and the user, causing the twist block 12 to slide on the inside of the user, thereby improving the stability of the twist block 12.

[0035] The working principle and use process of the utility model: when in use, the figure shows that the transparent protective cover 2 is fixed on the surface of the law enforcement recorder 1. When the transparent protective cover 2 needs to be opened, the push block 83 is pushed to move upward, and the push block 83 drives the positioning tooth plate 82 to move upward, and the positioning tooth plate 82 is separated from the positioning gear 81, and the positioning gear 81 loses its positioning, and the worm 7 also loses its positioning, and the worm 7 is rotated, and the worm 7 drives the worm wheel 6 to rotate, and the worm wheel 6 drives the card plate 4 to rotate, and the card plate 4 withdraws from the interior of the card slot 3, and the transparent protective cover 2 loses its fixation, and the transparent protective cover 2 can be rotated to separate from the law enforcement recorder 1. When the lens of the law enforcement recorder 1 needs to be protected, the above-mentioned opening steps can be reversed, thereby having the advantage of efficient protection.

[0036] To sum up: the law enforcement recorder lens protection device, through the coordinated use of the law enforcement recorder 1, the transparent protective cover 2, the card slot 3, the card plate 4, the installation box 5, the worm gear 6, the worm 7 and the anti-loosening mechanism 8, solves the problem of fixing the protective cover by utilizing the coordination of the limit buckle and the limit boss. The limit buckle is pushed by the torsion spring, and the limit buckle is in an external state. When the limit buckle is scratched by foreign objects, the limit buckle is easily separated from the limit boss, resulting in reduced stability of the protective cover. The protective cover has a greater probability of losing fixation, thereby reducing the protective effect of the protective cover.
