[0027] To address the problems in the background technology, this utility model proposes a GPS time synchronization tester with a drop-resistant structure, comprising:

[0028] The outer casing 1 has positioning notches 11 at its corners, and each positioning notch 11 has a plug-in portion 12.

[0029] The replaceable corner protector 2 is L-shaped, and its inner surface is provided with a matching insertion groove 21 corresponding to the insertion part 12. The insertion groove 21 cooperates with the insertion part 12, so that the replaceable corner protector 2 covers the corner of the outer shell 1.

[0030] Multiple detachable fixing structures 3 are provided, each of which connects the positioning notch 11 and the replaceable corner protector 2, so that the replaceable corner protector 2 can be detachably and fixedly installed into the positioning notch 11.

[0031] Combined with reference Figures 1 to 3As shown, in this embodiment, the outer shell 1 is made of high-strength composite material, which has good impact resistance. Its side shells and back cover are covered with a buffer layer made of silicone material. The shell contains electronic components such as a control motherboard, power supply, and GPS time synchronization module. Positioning notches 11 are provided at the four corners of the outer shell 1, and each positioning notch 11 has a plug-in part 12. The plug-in part 12 is a protruding structure, that is, a plug-in block integrally extended from the shell, with a T-shaped cross-section, used to mate with the plug-in slots 21 of the replaceable corner protectors 2. The replaceable corner protectors 2 are L-shaped overall. Users can choose corner protectors made of different materials, such as rubber, silicone, or metal, to meet different protection needs according to the usage environment. The inner surface of the corner protector forms a covering cavity that can cover the corners of the outer shell 1 to protect the corners from wear, scratches, or impacts. One side of its inner surface has a plug-in slot 21 that matches the plug-in part 12. By inserting the corresponding plug-in part 12 into the plug-in slot 21, a precise alignment installation is achieved. Furthermore, a detachable fixing structure 3 is provided between the positioning notch 11 of the outer shell 1 and the corner protector, ensuring that the corner protector can be detachably installed. This detachable fixing structure 3 can be a screw connection structure, a snap-on connection structure, a magnetic connection structure, a quick-release pin connection structure, a hook-and-loop connection structure, etc., which can fix the replaceable corner protector 2 at the positioning notch 11 of the outer shell 1 for protection, effectively dispersing external impact force and reducing the direct impact on the corners of the outer shell 1 when dropped or collided. The detachable and replaceable corner protector also allows users to flexibly replace the corner protector when it is damaged, reducing maintenance difficulty.

[0032] Furthermore, the detachable fixing structure 3 includes:

[0033] Countersunk hole 31, through which the replaceable corner protector 2 passes;

[0034] Threaded groove 32, the threaded groove 32 is provided in the positioning notch 11 and corresponds to the position of the countersunk hole 31;

[0035] A fastening screw 33 passes through the countersunk hole 31 and is threadedly connected to the threaded groove 32, thereby fixing the replaceable corner protector 2 into the positioning notch 11.

[0036] Combined with reference Figure 3As shown, in this embodiment, each replaceable corner protector 2 is fixedly installed to the positioning notch 11 of the outer casing 1 by four detachable fixing structures 3. A countersunk hole 31 is provided on the replaceable corner protector 2, allowing screws to pass through and ensuring a secure connection. A threaded groove 32 is provided within the positioning notch 11 and precisely aligns with the countersunk hole 31. A fastening screw 33 passes through the countersunk hole 31 and connects with the thread in the threaded groove 32, thereby fixing the replaceable corner protector 2. By tightening the fastening screw 33, the corner protector can be firmly installed within the positioning notch 11 of the outer casing 1, forming a strong protective structure. The fastening screw 33 allows the corner protector to be easily disassembled and replaced when needed, thus achieving a detachable function.

[0037] Combined with reference Figure 1 As shown, the replaceable corner protector 2 in this embodiment has a rounded corner on its outer surface, and its two inner surfaces are perpendicular to each other. The rounded corner design effectively disperses external impact forces, reduces damage to the outer casing 1 that may be caused by right-angle collisions, and enhances impact resistance. Furthermore, the rounded corner avoids sharp edges posing additional risks to the user's hands. The two inner surfaces of the corner protector are perpendicular to each other, forming a vertical angle between them, allowing the corner protector to fit tightly and securely into the positioning notch 11 of the device casing 1. This ensures a stable connection between the corner protector and the casing 1, better securing it in a specific position and preventing displacement or loosening during use.

[0038] Furthermore, the outer surface of the replaceable corner protector 2 is provided with an anti-slip texture to enhance friction when gripping. Specifically, the anti-slip texture can effectively prevent the device from slipping or becoming unstable when held. By increasing friction, the user can grip the device more firmly, especially during operation or in complex environments, providing a stronger sense of control to avoid slipping.

[0039] Furthermore, the replaceable corner protector 2 has beveled edges 22 and 23 to smooth its edges, creating an anti-slip texture. Specifically, transition beveled edges 22 and 23 are provided on both sides of the corner protector, making the edges no longer sharp right angles but presenting a smooth transition. This not only makes the corner protector look smoother and more aesthetically pleasing but also effectively reduces cuts or scratches that may be caused by sharp edges.

[0040] Combined with reference Figure 1As shown, in this embodiment, each of the plug-in portions 12 is located on one side of the top and bottom of the outer casing 1. The outer surface of the replaceable corner protector 2 has a connecting groove 24 that avoids the plug-in groove 21. Telescopic handles 4 are fixedly installed in two adjacent connecting grooves 24. Specifically, each plug-in portion 12 is located on both sides of the top and bottom of the outer casing 1, and the corner protector is connected to the plug-in portion 12 through the plug-in groove 21 and positioned in the positioning notch 11. The corner protector portion with the plug-in groove 21 is located at the top or bottom, while the other portion without the plug-in groove 21 is located on both sides. The outer surface of the corner protector without the plug-in groove 21 has a connecting groove 24, and these connecting grooves 24 avoid the position of the plug-in groove 21. Telescopic handles 4 are fixedly installed in adjacent connecting grooves 24. The telescopic handle 4 consists of a handle outer casing 1 and an internal handle core. One end of the handle core is connected to the internal structure of the outer casing 1, and the other end is fixed in the connecting groove 24 by bolts. By providing handles on both sides of the device, it is easy to hold and effectively prevents it from falling during use.

[0041] In summary, the beneficial effects of this embodiment are as follows: This embodiment adds replaceable corner protectors 2 to cover and protect the edges and corners of the equipment, and sets positioning notches 11 and insertion parts 12 at the edges and corners of the outer casing 1. By inserting the insertion slots 21 of the replaceable corner protectors 2 into the insertion parts 12, the corner protectors can be accurately installed in the correct position. Furthermore, the corner protectors are detachably and fixedly installed to the positioning notches 11 through the detachable fixing structure 3, which allows for convenient disassembly and replacement when needed, thereby achieving the detachable function.

[0042] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
