Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, specifically a flexible wearable ear-hook type OTC hearing aid fixing structure. Background Technology

[0002] With the aging population and the increasing prominence of hearing impairment, over-the-counter (OTC) hearing aids have gained popularity due to their convenience and accessibility. Ear-hook OTC hearing aids, in particular, have become one of the mainstream models on the market because of their ease of wear and resistance to falling out. However, existing ear-hook OTC hearing aid fixing structures still have some shortcomings in their use.

[0003] Based on the above, the inventors have discovered the following problems: most of the current flexible wearable ear-hook OTC hearing aid fixing structures are made of rigid or high-hardness materials. Although they can ensure the fixing effect to a certain extent, they are lacking in terms of wearing comfort.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a flexible wearable ear hook-type OTC hearing aid fixing structure in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible wearable ear-hook type OTC hearing aid fixing structure to solve the problem mentioned in the background art that most of the current flexible wearable ear-hook type OTC hearing aid fixing structures are made of rigid or high-hardness materials. Although they can ensure the fixing effect to a certain extent, they are lacking in wearing comfort.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A flexible wearable ear-hook type OTC hearing aid fixing structure includes a hearing aid body and a side plate fixedly connected to one side of the hearing aid body. A pair of fixing seats are installed on one side of the side plate. A fixing shaft is installed on the inner side of the fixing seat. A movable seat is rotatably connected to the outer side of the fixing shaft. A clamping plate is installed at one end of the movable seat. A torsion spring is fitted on the outer side of the fixing shaft. One end of the torsion spring is fixedly connected to the inner side of the movable seat. A threaded hole is opened on one side of the clamping plate. An adjustment mechanism for adjusting the clamping force is installed on the inner side of the threaded hole. Several anti-slip convex pads are installed on the side of the hearing aid body near the clamping plate. Several clamping pads are installed on the side of the clamping plate near the hearing aid body.

[0008] Furthermore, the adjusting mechanism includes a threaded rod, the outer side of which engages with a threaded hole in the clamping plate, and one end of the threaded rod contacts one side of the side plate.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by adjusting the engagement of the threaded rod in the adjustment mechanism with the threaded hole of the clamping plate, rotating the threaded rod can change its contact distance with the side plate, thereby adjusting the clamping angle and force of the clamping plate, achieving precise adjustment of the clamping force, and meeting the wearing needs of different users.

[0010] Furthermore, the clamping plate has an adjustment knob on the side away from the side plate, and the other end of the threaded rod is connected to one end of the adjustment knob.

[0011] The advantage of adopting the above-mentioned further solution is that the threaded rod is connected to the adjustment knob on one side of the clamping plate, which makes it convenient for users to manually rotate and adjust the threaded rod. The operation is simple and convenient, and it is easy to quickly adjust the clamping force according to one's own comfort.

[0012] Furthermore, the anti-slip convex pads and clamping pads are distributed at equal intervals, and the anti-slip convex pads and clamping pads are alternately arranged.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by using several equally spaced and alternately arranged anti-slip convex pads and clamping pads, the contact points and friction with the ear are increased, so that the hearing aid is evenly stressed, improving the stability of wearing it, while avoiding discomfort caused by local pressure.

[0014] Furthermore, a clamping groove is provided on one side of the clamping pad.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the clamping groove on one side of the clamping pad better conforms to the ear contour, increases the contact area, further improves the stability of the clamping, and prevents the hearing aid from shifting during activities.

[0016] Furthermore, both the anti-slip raised pad and the clamping pad are made of sponge material.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by using the non-slip convex pads and clamping pads made of sponge material, the softness and elasticity of the sponge can reduce the pressure on the ears and improve wearing comfort. At the same time, the sponge has a certain friction to enhance the fixation effect.

[0018] Furthermore, both corners of the side plate and the clamping plate are rounded.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the rounded corners of the side plates and clamping plates prevent sharp edges from scratching the ears or skin, improve the safety and comfort of wearing, and reduce discomfort during use.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: This flexible wearable ear-hook OTC hearing aid fixing structure achieves hearing aid function through the hearing aid body. The clamping plate can rotate through the cooperation of the side plate, fixed seat, fixed shaft, and movable seat, facilitating wearing. A torsion spring provides clamping force to the movable seat and clamping plate, achieving initial fixation to the ear. The clamping force can be adjusted through an adjustment mechanism to adapt to different users' ear sizes. Anti-slip convex pads and clamping pads increase friction with the ear, improving wearing stability and comfort, and preventing the hearing aid from falling off. The threaded rod in the adjustment mechanism engages with the threaded hole of the clamping plate; rotating the threaded rod changes its contact distance with the side plate, thereby adjusting the clamping angle and force of the clamping plate, achieving precise adjustment of the clamping force to meet the wearing needs of different users. An adjustment knob on one side of the clamping plate connects to the threaded rod, allowing users to manually rotate and adjust the threaded rod, making operation simple and convenient. This design allows for quick adjustment of the clamping force based on individual comfort. Several evenly spaced and alternately arranged anti-slip raised pads and clamping pads increase contact points and friction with the ear, ensuring even force distribution and improving wearing stability. This also prevents discomfort caused by localized pressure. The clamping groove on one side of the clamping pad better conforms to the ear's contour, increasing the contact area and further enhancing clamping stability, preventing the hearing aid from shifting during movement. The sponge-material anti-slip raised pads and clamping pads utilize the sponge's softness and elasticity to reduce pressure on the ear, improving wearing comfort. The sponge also provides friction, enhancing the fixation effect. The rounded corners of the side plates and clamping plates prevent sharp edges from scratching the ear or skin, improving wearing safety and comfort, and reducing discomfort during use. This invention effectively achieves clamping and fixing functions, and the clamping force is adjustable, making it highly practical. Attached Figure Description

[0031] 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.
