[0024] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0025] The following describes in detail, with reference to the accompanying drawings, a quick-assembly and disassembly hearing aid housing according to an embodiment of the present invention.

[0026] Example

[0027] For easier understanding, please refer to Figures 1 to 3 This utility model provides an embodiment of a quick-release hearing aid housing, comprising a first housing 1 and a second housing 2, which are engaged with each other. The first housing 1 is provided with a locking mechanism. The locking mechanism includes a plurality of sliding grooves 3, a movable opening 4, a movable plate 6, a first locking member 7, a fixing member 8, and a fixing block 12. The plurality of sliding grooves 3 are formed on the outer wall of the first housing 1, the movable opening 4 is formed on the groove wall of the sliding groove 3, the movable plate 6 is slidably installed on the inner wall of the movable opening 4, the first locking member 7 is fixedly installed on one side of the movable plate 6, the fixing block 12 is installed in the sliding groove 3 on the first housing 1, and the fixing member 8 is fixedly installed on one side of the movable plate 6.

[0028] It should be noted that, by setting up a snap-fit ​​mechanism, the moving plate 6 slides in the moving port 4, and the first snap-fit ​​member 7 is installed on the moving plate 6. As the moving plate 6 slides and moves, when fixing the first housing 1 and the second housing 2, the second housing 2 closes to one side of the first housing 1. Sliding the moving plate 6 causes the first snap-fit ​​member 7 to move to the second snap-fit ​​member 15 and snap-fit ​​with the second snap-fit ​​member 15, thus fixing the first housing 1 and the second housing 2. When disassembling the first housing 1 and the second housing 2, moving the moving plate 6 causes the first snap-fit ​​member 7 and the second snap-fit ​​member 15 to disengage, thus removing the fixation between the first housing 1 and the second housing 2, allowing for quick assembly and disassembly of the first housing 1 and the second housing 2, facilitating the maintenance of the hearing aid. The fixing member 8 is located on the outer wall of the first housing 1, and the moving plate 6 can be moved by pushing the fixing member 8 with a finger from the outside.

[0029] In some embodiments, such as Figure 2 , Figure 3As shown, sliders 5 are fixedly installed on both sides of the inner wall of the movable port 4, and grooves are provided on both sides of the movable plate 6. The movable plate 6 is slidably installed on the sliders 5 through the grooves. A sealing element 10 is fixedly installed on the inner wall of the movable port 4, and the inner ring of the sealing element 10 is fixedly installed on the outer wall of the movable plate 6.

[0030] It should be noted that by setting the slider 5, the two sides of the moving plate 6 are limited, so that the moving plate 6 can move at a fixed angle. By setting the sealing element 10, which can be a rubber sheet, thermoplastic polyurethane film, etc., thermoplastic polyurethane film is preferred because it has high strength and good flexibility, and seals the moving port 4.

[0031] In some embodiments, such as Figure 2 As shown, the inner wall of the first housing 1 is provided with a plurality of fixing holes 11, the positions of the fixing holes 11 are corresponding to the slide groove 3, the fixing block 12 is fixedly installed on the inner wall of the fixing hole 11 by screws, one end of the fixing block 12 extends into the slide groove 3, and a fixing groove 9 is provided on one side of the fixing member 8, the fixing groove 9 is engaged with one end of the corresponding fixing block 12.

[0032] It should be noted that in this example, when the first snap-fit ​​component 7 moves to the position corresponding to the second snap-fit ​​component 15, the fixing component 8 is pushed to the fixing block 12, and the fixing groove 9 on the fixing component 8 snaps into the fixing block 12, fixing the position of the fixing component 8, thereby fixing the position of the first snap-fit ​​component 7.

[0033] In this example, pushing the fastener 8 in the opposite direction can disengage the fastening groove 9 on the fastener 8 from the fastening block 12, thus canceling the fastener 8's fixation.

[0034] In this example, the fastener 8 has anti-slip texture on one side.

[0035] In this example, by setting a detachable fixing block 12, it is convenient to replace the fixing block 12 when it is severely worn.

[0036] In some embodiments, such as Figure 3 As shown, the movable plate 6 has several first threaded holes on one side, and the fixing member 8 has several mounting openings 13 on one side. The inner wall of the mounting opening 13 has a second threaded hole at one end. The positions of the first threaded holes and the second threaded holes correspond to each other. The fixing member 8 is fixedly installed on one side of the movable plate 6 by screws. The inner wall of the second housing 2 is integrally formed with a retaining ring 14. The inner wall of the retaining ring 14 is fixedly installed with a second snap-fit ​​member 15. The second snap-fit ​​member 15 is snapped into the corresponding first snap-fit ​​member 7.

[0037] It should be noted that the fastener 8 is fixed to the movable plate 6 with screws, which makes it easy to replace the worn fastener 8.

[0038] In this example, the screws that fix the fastener 8 are installed on the corresponding first threaded hole and second threaded hole.

[0039] In this example, the connection between the second housing 2 and the first housing 1 is facilitated by setting the retaining ring 14.

[0040] Working principle: When fixing the first housing 1 and the second housing 2, push the fixing member 8 with your finger to make the fixing member 8 engage with the fixing block 12. At this time, the moving plate 6 moves and drives the first engaging member 7 to the second engaging member 15, which engages with the second engaging member 15 to fix the first housing 1 and the second housing 2.

[0041] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
