[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model provides an ear shell that is easy to disassemble and repair, comprising two main shells 1, each divided into a left half and a right half. A convenient disassembly and repair assembly 2 is provided between the left and right halves. The assembly includes an insertion block 201, which is fixedly connected to the end face of the left half of the main shell 1. An installation hole 202 is provided in the middle of the insertion block 201. Two locking blocks 203 are slidably connected to the inner wall of the installation hole 202. Two first springs 204 are provided inside the installation hole 202, with both ends of the first springs 204 fixedly connected to the locking blocks 203. A sliding groove 205 is provided in the right half of the main shell 1. ， The sliding groove 205 has two snap-fit ​​grooves 220 inside. The inner wall of the sliding groove 205 is slidably connected to the insertion block 201, and the inner wall of the snap-fit ​​groove 220 is snapped into the snap-fit ​​block 203. With the convenient disassembly and assembly component 2, when the insertion block 201 enters the sliding groove 205, the two snap-fit ​​blocks 203 are squeezed by the inner wall of the sliding groove 205, which causes the first spring 204 to contract. When the insertion block 201 is inserted into place, the first spring 204 extends, which pushes the two snap-fit ​​blocks 203 to pop out and snap into the inner wall of the snap-fit ​​groove 220, thereby completing the assembly of the two main shells 1 and improving the ease of installation.

[0029] Furthermore, a rotating column 206 is rotatably connected to the inner wall of the sliding groove 205, and a cam 207 is fixedly connected to the surface of the rotating column 206. A pusher frame 208 is slidably connected to the inner wall of the sliding groove 205, and two second springs 209 are fixedly connected to the side wall of the pusher frame 208. The left end of the second spring 209 is fixedly connected to the inner wall of the snap-fit ​​groove 220. Through the interaction of the rotating column 206, the cam 207, and the second spring 209, rotating the rotating column 206 drives the cam 207 to rotate. When the cam 207 rotates, the surface of the cam 207 presses against the side wall of the pusher frame 208, causing the pusher frame 208 to move and the second spring 209 to retract. When the pusher frame 208 moves, the side wall of the pusher frame 208 pushes the snap-fit ​​block 203, causing the snap-fit ​​block 203 to retract into the inner wall of the mounting hole 202. Thus, the two main shells 1 can be disassembled to repair or replace the electronic components inside the two main shells 1.

[0030] Furthermore, two limiting grooves 210 are provided on the end face of the right half of the main body shell 1, and two limiting posts 211 are fixedly connected to the end face of the left half of the main body shell 1. The size of the limiting posts 211 matches the size of the limiting grooves 210. By using the limiting grooves 210 and the limiting posts 211 in cooperation, it is easy to limit the two main body shells 1 and improve the precision of installation.

[0031] Furthermore, a threaded tube 212 is provided on the side wall of the main shell 1. A threaded head 213 is threadedly connected to the inner wall of the threaded tube 212. Both the threaded tube 212 and the threaded head 213 are divided into a left half and a right half. The two threaded tube halves form a complete threaded tube 212, and the two threaded head halves form a complete threaded head 213. The left half of the threaded tube 212 is fixedly connected to the left half of the main shell 1, and the right half of the threaded tube 212 is fixedly connected to the right half of the main shell 1. A connecting plate 216 is fitted onto the surface of the threaded tube 212. The side wall of the threaded head 213 abuts against the side wall of the connecting plate 216. The threaded head 213 and the threaded head 216 work together. Rotating the threaded head 213 will cause the side wall of the threaded head 213 to press against the side wall of the connecting plate 216, thereby fixing the connecting plate 216. When the threaded head 213 is unscrewed, the connecting plate 216 can be removed from the surface of the threaded tube 212, which makes it easy to install or remove the connecting plate 216.

[0032] Furthermore, a positioning groove 214 is provided on the end face of the right half of the threaded head 213, and a positioning block 215 is fixedly connected to the end face of the left half of the threaded head 213. The size of the positioning block 215 matches the size of the positioning groove 214. The positioning groove 214 and the positioning block 215 cooperate with each other to improve the tightness of the connection between the two threaded heads 213.

[0033] Furthermore, the sidewall of the connecting plate 216 is provided with multiple protective grooves 217, and the surface of the two connecting plates 216 is fitted with the same connecting strip 218. Two bolts 219 are threaded to both sides of the connecting strip 218, and one end of each bolt 219 abuts against the sidewall of the connecting plate 216. The bolts 219 facilitate the installation and disassembly of the connecting plate 216 and the connecting strip 218, thereby improving the overall ease of use.

[0034] Working principle: Through the convenient disassembly and assembly component 2, when the insertion block 201 enters the interior of the sliding groove 205, the two locking blocks 203 are squeezed by the inner wall of the sliding groove 205, causing the first spring 204 to contract. When the insertion block 201 is inserted into place, the first spring 204 extends, thereby pushing the two locking blocks 203 to pop out and engage with the inner wall of the locking groove 220, thus completing the assembly of the two main shells 1 and improving the ease of installation. Through the coordinated use of the rotating column 206, cam 207 and the second spring 209, rotating the rotating column 206 drives the cam 207 to rotate. When the cam 207 rotates, the surface of the cam 207 presses against the side wall of the push frame 208, causing the push frame 208 to move and the second spring 209 to contract. When the push frame 208 moves, the side wall of the push frame 208 pushes the locking block 203, causing the locking block 203 to retract into the inner wall of the mounting hole 202, thus allowing the two main shells 1 to be disassembled for repair or replacement of the internal electronic components.
