Technical Field

[0001] The utility model relates to the technical field of dustproof nets for mobile phone receivers, in particular to a dustproof net for receivers which is easy to install. Background Art

[0002] Mobile phones are an indispensable communication tool in life. They not only gather information about work and life, but are also the main tool for entertainment and leisure. Therefore, the importance of mobile phones is increasingly reflected, resulting in the current situation that mobile phones are always in hand in modern life. The mobile phone receiver, as a sound output component, is an indispensable key link, and the dustproof net can protect the receiver from external dust.

[0003] Existing mobile phone receiver dust screens are often installed by gluing. When the receiver dust screen is used for a long time, a lot of dust may accumulate inside it. At this time, the entire dust screen needs to be disassembled and the dust on the dust screen needs to be cleaned. However, the dust screen fixed by gluing is more cumbersome to disassemble, and it is also more complicated to reinstall the dust screen after the dust is cleaned. Therefore, we propose a receiver dust screen that is easy to install. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. The existing mobile phone receiver dustproof net is often installed by gluing. When the receiver dustproof net is used for a long time, a lot of dust may accumulate inside it. At this time, the entire dustproof net needs to be disassembled and the dust on the dustproof net needs to be cleaned. However, the dustproof net fixed by gluing is more cumbersome to disassemble and it is also more complicated to reinstall the dustproof net after the dust is cleaned.

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: an earpiece dustproof net that is easy to install, comprising a mobile phone body 1, a mounting groove 2 is provided at the top of the mobile phone body 1 near the back, the mounting groove 2 can be used to install a mounting seat 201, the mounting seat 201 is arranged inside the mounting groove 2, and a fixing frame 202 is symmetrically arranged at the bottom of the mounting seat 201, the fixing frame 202 can fix the position of a telescopic rod 203 and a spring 205, the telescopic rod 203 is fixed on the outer wall of the fixing frame 202, and a limiting block 204 is provided at one end of the telescopic rod 203 away from the fixing frame 202, and the limiting block 204 can be stuck in the limiting block A spring 205 is provided inside the groove 206, between the fixing frame 202 and the limit block 204 and on the outer periphery of the telescopic rod 203. The spring 205 can help the limit block 204 to reset. A limit groove 206 is provided on the inner side wall of the mounting groove 2 corresponding to the limit block 204. A disassembly hole 101 is provided on the back of the mobile phone body 1 corresponding to the limit groove 206. A disassembly rod 102 is provided inside the disassembly hole 101. By inserting an external card remover into the disassembly hole 101 and pushing the disassembly rod 102, the disassembly rod 102 can push the limit block 204, thereby removing the dust net 207. Example

[0029] like Figure 1-4As shown, the disassembly hole 101 is connected with the interior of the limiting groove 206, the disassembly rod 102 is adapted to the disassembly hole 101, and the disassembly rod 102 is slidably connected with the disassembly hole 101. The disassembly hole 101 is connected with the interior of the limiting groove 206, so that the disassembly rod 102 can enter into the interior of the limiting groove 206 and can push the limiting block 204 inside the limiting groove 206, so that the dustproof net 207 can be disassembled.

[0030] Circular baffles 103 are provided on the inner wall of the disassembly hole 101 near the front and back sides, and a circular stopper 104 is installed on the outer wall of the disassembly rod 102. The design of the circular baffles 103 and the circular stopper 104 can well limit the disassembly rod 102 so that the disassembly rod 102 will not fall.

[0031] The diameter of the circular baffle 103 is slightly smaller than the diameter of the circular stop block 104, so that the disassembly rod 102 can be limited and will not fall easily. By limiting the disassembly rod 102, the disassembly rod 102 can better apply force to the limit block 204, so that the dustproof net 207 can be removed more conveniently.

[0032] The limit block 204 is adapted to the limit groove 206 and is designed in a hemispherical shape. The limit block 204 designed in a hemispherical shape enables the disassembly rod 102 to better push the limit block 204 so that the limit block 204 can be moved out of the limit groove 206, thereby enabling the dust screen 207 to be disassembled.

[0033] A dustproof net 207 is installed on the top of the mounting base 201. The dustproof net 207 is made of stainless steel. The dustproof net 207 made of stainless steel has a good dustproof effect and will not be corroded by sweat or rainwater, and has a long service life.

[0034] The working process of the utility model is as follows: when installing a receiver dust screen that is easy to install, first, you only need to insert the entire mounting base 201 into the interior of the mounting slot 2, and align the limit block 204 with the limit slot 206. When the entire mounting base 201 is lowered, the limit block 204 will drive the telescopic rod 203 and the spring 205 to shrink. When the limit block 204 is lowered to the limit slot 206, the spring 205 will reset, so that the limit block 204 is inserted into the interior of the limit slot 206 under the action of the spring 205, and the installation of the dust screen 207 is completed, which is relatively convenient. When disassembling, the staff can extend the external card remover into the interior of the disassembly hole 101 and push the external card remover When the disassembly rod 102 is displaced, the disassembly rod 102 will enter the interior of the limit groove 206 and apply a force to the limit block 204, so that the limit block 204 can be displaced toward the fixing frame 202 through the telescopic rod 203 and the spring 205, so that the limit block 204 can be separated from the limit groove 206. At this time, the staff can very conveniently take out the entire mounting base 201 to complete the disassembly of the dustproof net 207. The dustproof net 207 can be disassembled more quickly. Compared with the existing mobile phone earpiece dustproof net, it can be more convenient to install and disassemble, and there is no need to disassemble the entire mobile phone, which improves the convenience and practicality of the mobile phone earpiece dustproof net during installation and disassembly.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
