Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6, the present utility model provides a technical solution: a snap - type fixing mechanism for a mobile phone cover plate, including a mobile phone body 1 and a cover plate body 2. L - shaped grooves 11 are opened at the four corners of the inner surface of the mobile phone body 1. A disassembly opening 6 is penetrated through the inner bottom end of the L - shaped groove 11. A dust plug 7 is rotatably connected to the inner side of the disassembly opening 6. A sealing gasket 12 is fixedly connected to the surface of the mobile phone body 1 close to the cover plate body 2. At the four corners of the inner surface of the cover plate body 2, a clamping block 14 is fixedly connected through a connecting rod 13. A sealing groove 15 is opened on the surface of the cover plate body 2 close to the mobile phone body 1. Through the structures such as the clamping block 14, the L - shaped groove 11 and the disassembly groove, when installing the cover plate body 2, press the clamping block 14 on the surface of the cover plate body 2 against the position of the L - shaped groove 11 of the mobile phone body 1 until the clamping block 14 is stuck at the innermost end of the L - shaped groove 11 to complete the installation of the cover plate body 2. When disassembling, a thimble is pushed inward through the disassembly opening 6 to push the four clamping blocks 14 inward simultaneously, and then the cover plate body 2 can be directly removed from the rear surface of the mobile phone body 1, effectively avoiding the problem that the traditional method of fixing the mobile phone cover plate mainly relies on screws to ensure the structural stability between the cover plate and the mobile phone body. Although this fixing method can indeed provide a firm connection to ensure that the cover plate does not fall off easily during normal use of the mobile phone, it also brings inconvenience in operation. When users need to replace the cover plate or perform internal maintenance, they must use tools such as screwdrivers for disassembly, which not only increases the complexity of maintenance but also may prolong the maintenance time. Through the setting of the limiting block 8 and the telescopic rod structure 10, during installation, the telescopic rod is inserted into the inner side of the limiting block 8 to limit the positions of the mobile phone body 1 and the cover plate body 2 to prevent misalignment during installation. Through the setting of the sealing gasket 12 and the sealing groove 15, the sealing performance of the installation between the mobile phone body 1 and the cover plate body 2 is achieved. And when water seeps between the mobile phone body 1 and the cover plate body 2, the expansion rubber of the sealing gasket 12 swells when encountering water to achieve the purpose of waterproofing.

[0026] In the present utility model, preferably, a camera 5 is installed at the upper end of the front surface of the mobile phone body 1.

[0027] In the present utility model, preferably, a screen 4 is installed in the middle part of the front surface of the mobile phone body 1.

[0028] In the present utility model, preferably, buttons 3 are installed at the lower end of the front surface of the mobile phone body 1.

[0029] In the present utility model, preferably, a limiting block 8 is fixedly connected to the middle part of the inner surface of the mobile phone body 1, and a limiting groove is opened inside the limiting block 8.

[0030] In the present utility model, preferably, a telescopic rod structure 10 is fixedly connected to the middle part of the inner surface of the cover plate body 2.

[0031] In the present utility model, preferably, a spring structure 9 is provided on the surface of the telescopic rod structure 10. By means of the provided spring structure 9, when the cover plate body 2 is installed, the spring structure 9 is in a compressed state. After the four clamping blocks 14 are simultaneously pressed inward, when the spring structure 9 loses the acting force of the clamping blocks 14 and the L-shaped groove 11, the restoring elastic force of the spring structure 9 will eject the cover plate body 2 in the opposite direction of the mobile phone body 1, thereby achieving the purpose of automatically ejecting the cover plate body 2 and further facilitating the disassembly process of the cover plate body 2.

[0032] Working principle and usage process of the present utility model: During use, first, align the clamping blocks 14 of the mobile phone cover plate body 2 with the L-shaped grooves 11 of the mobile phone body 1, and press the cover plate body 2 until the clamping blocks 14 are firmly clamped at the innermost end of the L-shaped grooves 11 to complete the installation of the cover plate body 2. At this time, the sealing groove 15 of the cover plate body 2 is in close contact with the sealing gasket 12 of the mobile phone body 1, ensuring the sealing performance between the mobile phone body 1 and the cover plate body 2. If moisture seeps between the mobile phone body 1 and the cover plate body 2, the expansion rubber of the sealing gasket 12 will expand when encountering water to achieve the waterproof effect. When it is necessary to replace the cover plate or perform internal maintenance, use a thimble tool to push inward through the disassembly opening 6 to simultaneously push the four clamping blocks 14 inward, so that the cover plate body 2 can be directly removed from the rear surface of the mobile phone body 1. During the installation process, the telescopic rod is inserted into the inner side of the limit block 8 to limit the positions of the mobile phone body 1 and the cover plate body 2 to prevent misalignment during installation. The spring structure 9 is in a compressed state when the cover plate body 2 is installed. After the four clamping blocks 14 are pressed inward, the spring structure 9 loses the acting force of the clamping blocks 14 and the L-shaped groove 11. At this time, the restoring elastic force of the spring structure 9 will eject the cover plate body 2 in the opposite direction of the mobile phone body 1 to achieve the purpose of automatically ejecting the cover plate body 2 and further facilitating the disassembly process of the cover plate body 2.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
