[0020] In an embodiment of this utility model, a three-proof protective cover 100 for anti-loss device 200 is provided to provide basic waterproof, dustproof and shockproof (three-proof) protection and extend the service life of anti-loss device 200.

[0021] like Figures 1-5 As shown, the anti-loss device's three-proof protective cover 100 includes: an upper cover 10, two connecting blocks 20, and a lower cover 30. The upper cover 10, connecting blocks 20, and lower cover 30 can all be made of stainless steel, and their surfaces can be polished or matte.

[0022] The top cover 10 has an arc-shaped receiving groove 101. The arc parameters of the receiving groove 101 can be designed according to the arc surface of the anti-loss device 200. The edge of the receiving groove 101 forms an annular slot 102.

[0023] Furthermore, the upper cover 10 has an observation hole 103 communicating with the receiving groove 101. A transparent cover (not shown) is provided on the observation hole 103. Therefore, the status of the anti-loss device 200 can be viewed from the outside through the observation hole 103. In one embodiment, the observation hole 103 is a circular hole, and the portion of the receiving groove 101 outside the observation hole 103 is evenly arranged around the transparent cover, thereby placing the observation hole 103 at the center of the upper cover 10, facilitating processing and improving the appearance.

[0024] Two connecting blocks 20 are fixed to opposite sides of the upper cover 10. Each connecting block 20 has a connecting hole 201 for attaching an external rope. Therefore, both ends of the rope are connected to the two connecting blocks 20 respectively to attach the protective cover to the rope for easy carrying. Furthermore, the connecting block 20 is elongated and curved towards the lower cover 30.

[0025] The connecting hole 201 is elongated and parallel to the width direction of the connecting block 20. In one embodiment, the end of the connecting block 20 away from the upper cover 10 has a through hole 202 communicating with the corresponding connecting hole 201, and the through hole 202 is connected to the middle of the connecting hole 201. The loop at one end of the rope passes through the through hole 202 and extends into the connecting hole 201. Then, by twisting the loop at one end of the rope, the loop is laid flat inside the connecting hole 201, thus serving a connection function without detaching from the connecting hole 201.

[0026] The lower cover 30 includes a cover plate 31 and a retaining ring 32 disposed on the edge of the cover plate 31. The retaining ring 32 is annular and adapted to the retaining groove 102. Specifically, the retaining ring 32 is used to press against the inner wall of the retaining groove 102 to fasten the lower cover 30 and the upper cover 10. The cover plate 31 is pressed against one side of the anti-loss device 200 so that the side of the anti-loss device 200 away from the cover plate 31 is attached to the inner wall of the receiving groove 101, thereby covering the anti-loss device 200 between the upper cover 10 and the lower cover 30.

[0027] Furthermore, at least one notch 301 is provided on the outer side of the retaining ring 32. The cross-section of the notch 301 may be semi-circular. The opening of the notch 301 is arranged radially outward along the retaining ring 32, so that when the user needs to open the lower cover 30, he / she can insert his / her fingernail or a tool into the notch 301 to pry out the lower cover 30.

[0028] In some embodiments, a silicone pad (not shown in the figure) is attached to the inner wall of the receiving slot 101 and the side of the cover plate 31 near the upper cover 10. The silicone pad is used to cover the surface of the anti-loss device 200, thereby improving the anti-vibration performance of the anti-loss device 200.

[0029] In summary, the three-proof protective cover 100 for the anti-loss device provided by this utility model utilizes the interplay between the arc-shaped receiving groove 101 of the upper cover 10 and the cover plate 31 of the lower cover 30, along with the interference fit between the retaining ring 32 and the retaining groove 102 to form a tight enclosure. This presses the anti-loss device 200 between the inner wall of the receiving groove 101 and the cover plate 31, thereby restricting its movement. Simultaneously, the connecting hole 201 on the connecting block 20 facilitates the attachment of an external strap for convenient carrying. This structure, through mechanical interference and arc-shaped fitting principles, ensures that the anti-loss device 200 remains securely within the protective cover, and the overall design disperses external impact forces. Therefore, the anti-loss device 200 is firmly encased within the protective cover, reducing the risk of it falling off due to vibration or collision. The connecting block 20 is designed for easy carrying via a strap, improving usability. Furthermore, the tight fit between the upper cover 10 and the lower cover 30 provides basic waterproof, dustproof, and shockproof (three-proof) protection, extending the service life of the anti-loss device 200.
