Description

Technical Field

[0001] This invention relates to the field of hearing aid technology, specifically to an anti-loosening air conduction hearing aid. Background Technology

[0002] An air conduction hearing aid is a behind-the-ear digital programmable hearing aid that consists of a miniature microphone, signal amplification and processing circuit, a miniature earphone (speaker), a shell, a switch, and a sound tube.

[0003] Air conduction hearing aids are worn similarly to normal headphones. However, during use, the connection between the headphone and the user's ear canal can easily become loose, requiring the user to frequently adjust the headphone's position, which is very inconvenient.

[0004] Therefore, in order to solve the above problems, the present invention proposes an anti-loosening air conduction hearing aid. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides an anti-loosening air conduction hearing aid.

[0006] The technical solution adopted by this invention to solve its technical problem is: an anti-loosening air conduction hearing aid, including a mounting ring, an inner ring of which is provided with a soft padding layer, an annular groove at the top of the mounting ring, symmetrically arranged rotating rods rotatably connected inside the annular groove, two rotating rods being fixedly connected to the rotating ring, symmetrically arranged mounting boxes being fixedly connected to the outer wall of the mounting ring, each of the two mounting boxes having a fixing mechanism on its top wall, a fixing gear being fixedly connected to the bottom of each of the two rotating rods corresponding to the fixing mechanism, and a connecting rod being rotatably connected inside each of the two mounting boxes, the two connecting rods being connected to the rotating ring. Each mounting box has a fixed drive gear at its corresponding position inside the mounting rod. Both mounting boxes have a cross-shaped groove at their bottom ends and symmetrically arranged through slots at their bottom ends. Symmetrically arranged guide blocks are fixedly connected inside each of the through slots. Both mounting boxes have an abutment mechanism near their bottom ends. Multiple guide blocks are slidably connected to a driven rack. A mounting rod is fixedly connected between multiple driven racks. Each mounting rod has a pressing wheel on its opposite side. Both mounting boxes have a transmission mechanism inside and an elastic strap at their bottom ends.

[0007] Specifically, each of the fixing mechanisms includes two round rods, with a combined baffle fixedly connected to the top of each round rod, and an annular plate fixedly connected to the bottom of each round rod. The bottom of each annular plate is provided with several toothed blocks, and a fixing spring is fixedly connected to the top of each annular plate.

[0008] Specifically, the round rods in the fixing mechanism are all slidably connected to the top wall of the mounting box near the mounting ring, several toothed blocks in the fixing mechanism are all meshed with the fixing gear, and the top ends of the fixing springs in the fixing mechanism are all fixedly connected to the bottom end of the top wall of the mounting box.

[0009] Specifically, each of the abutting mechanisms includes a limiting rod, an abutting rod slidably connected to the limiting rod at a position inside the mounting box, an abutting spring fixedly connected to the abutting rod at a position corresponding to the limiting rod, a pressure bearing seat fixedly connected to the abutting rod at a position corresponding to the compression wheel, and an abutting ring fixedly connected to one side of each abutting rod.

[0010] Specifically, the limiting rods in the abutting mechanism are all fixedly connected to the inside of the mounting box near the bottom, the bottom ends of the abutting rods in the abutting mechanism all pass through the cross-shaped grooves, and the abutting springs in the abutting mechanism are all fixedly connected to the inner wall of the mounting box.

[0011] Specifically, each of the transmission mechanisms includes symmetrically arranged transmission rods, each transmission rod having a driven gear fixedly connected to the position corresponding to the driven rack, each transmission rod having a clamping rod fixedly connected to both sides of the cross-shaped groove, and each clamping rod having a clamping block fixedly connected to the position corresponding to the elastic strap.

[0012] Specifically, the transmission rods in the transmission mechanism are symmetrically rotatably connected to the middle position inside the mounting box, the driven gears in the transmission mechanism are all meshed with the driven rack, and the bottom ends of the clamping rods in the transmission mechanism pass through both sides of the cross-shaped groove.

[0013] Specifically, each of the driving gears is meshed with another driving gear, each of the driving gears is meshed with a driven rack, and a handle is fixedly connected to the outer wall of the rotating ring.

[0014] The beneficial effects of this invention are: (1) When the present invention is in normal use, the mechanism can be operated in conjunction by rotating the rotating ring. The linkage of the mechanism will drive the two driven racks to move upward. When the two driven racks move upward, they will apply pressure to the pressure seat through the extrusion wheel. The pressure seat under pressure will cause the abutment rod to press against the earphone. At this time, the earphone will be pressed and will move towards the inside of the user's ear canal and be fixed. The fixed position of the abutment rod at this time can prevent the earphone from becoming loose when worn, avoiding the trouble of the user having to frequently adjust the position of the earphone.

[0015] (2) When the driven rack moves upward, the invention will also cause the two driven gears to rotate simultaneously. The rotation of the two driven gears will cause the clamping rod to rotate in the middle direction at the same time. The rotation of the two clamping rods will cause the top of the elastic strap to move towards the middle direction to form a ring. When the user wears the installation ring normally, the two rings formed by the elastic straps can wrap around the user's ears, providing a certain stability for wearing the installation ring. It is very convenient to operate and is worth promoting. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-5As shown, the present invention discloses an anti-loosening air conduction hearing aid, comprising a mounting ring 1, an inner ring of which is provided with a soft padding layer 2, an annular groove 3 at the top of the mounting ring 1, symmetrically arranged rotating rods 4 rotatably connected inside the annular groove 3, two rotating rods 4 being fixedly connected to a rotating ring 5, symmetrically arranged mounting boxes 6 being fixedly connected to the outer wall of the mounting ring 1, each mounting box 6 having a fixing mechanism 7 on its top wall, and fixing gears 8 fixedly connected to the bottom of each rotating rod 4 corresponding to the fixing mechanism 7, and connecting rods 9 rotatably connected inside each mounting box 6, with the connecting rods 9 and rotating rods 4 corresponding to the positions inside the mounting box 6. A drive gear 10 is fixedly connected to each of the two mounting boxes 6. A cross-shaped groove 11 is opened at the bottom of each of the two mounting boxes 6. A symmetrically arranged through groove 12 is opened at the bottom of each of the two mounting boxes 6. A symmetrically arranged guide block 13 is fixedly connected inside each of the through grooves 12. An abutment mechanism 14 is provided at the bottom of each of the two mounting boxes 6. A driven rack 15 is slidably connected to each of the multiple guide blocks 13. A mounting rod 16 is fixedly connected between each of the multiple driven racks 15. A pressing wheel 17 is provided on the opposite side of each of the two mounting rods 16. A transmission mechanism 18 is provided inside each of the two mounting boxes 6. An elastic strap 19 is provided at the bottom of each of the two mounting boxes 6.

[0021] Specifically, each of the fixing mechanisms 7 includes two round rods 71, the top ends of which are all fixedly connected to an integral baffle 72, the bottom ends of which are all fixedly connected to an annular plate 73, the bottom ends of which are provided with several toothed blocks 74, and the top ends of which are all fixedly connected to a fixing spring 75.

[0022] Specifically, the round rods 71 ​​in the fixing mechanism 7 are all slidably connected to the top wall of the mounting box 6 near the mounting ring 1. Several toothed blocks 74 in the fixing mechanism 7 are all meshed with the fixing gear 8. The top ends of the fixing springs 75 in the fixing mechanism 7 are all fixedly connected to the bottom end of the top wall of the mounting box 6. The toothed blocks 74 can fix the fixing gear 8.

[0023] Specifically, each of the abutting mechanisms 14 includes a limiting rod 141, and each limiting rod 141 is slidably connected to an abutting rod 142 at a position inside the mounting box 6. Each abutting rod 142 is fixedly connected to an abutting spring 143 at a position corresponding to the limiting rod 141. Each abutting rod 142 is fixedly connected to a pressure bearing seat 144 at a position corresponding to the compression wheel 17. Each abutting rod 142 is fixedly connected to an abutting ring 145 on one side.

[0024] Specifically, the limiting rods 141 in the abutting mechanism 14 are all fixedly connected to the inside of the mounting box 6 near the bottom. The bottom ends of the abutting rods 142 in the abutting mechanism 14 all pass through the cross-shaped grooves 11. The abutting springs 143 in the abutting mechanism 14 are all fixedly connected to the inner wall of the mounting box 6. The cross-shaped grooves 11 can provide basic movement space for the abutting rods 142.

[0025] Specifically, each of the transmission mechanisms 18 includes symmetrically arranged transmission rods 181, each transmission rod 181 is fixedly connected to a driven gear 182 at the position corresponding to the driven rack 15, each transmission rod 181 is fixedly connected to a clamping rod 183 at the position corresponding to both sides of the cross-shaped groove 11, and each clamping rod 183 is fixedly connected to a clamping block 184 at the position corresponding to the elastic strap 19.

[0026] Specifically, the transmission rods 181 in the transmission mechanism 18 are symmetrically rotatably connected to the middle position inside the mounting box 6. The driven gears 182 in the transmission mechanism 18 are all meshed with the driven rack 15. The bottom ends of the clamping rods 183 in the transmission mechanism 18 all pass through both sides of the cross-shaped groove 11, and the driven rack 15 can easily drive the driven gears 182 to rotate.

[0027] Specifically, each of the driving gears 10 is meshed with another driving gear 10, and each of the driving gears 10 is meshed with a driven rack 15. A handle 20 is fixedly connected to the outer wall of the rotating ring 5, and the driving gear 10 can easily drive the other driving gear 10 to rotate.

[0028] In use, first, place the mounting ring 1 on the user's head normally, then place the two elastic straps 19 around the bottom of the ears, and then put on the headphones. Next, rotate the rotating ring 5. When the rotating ring 5 is rotated upward, it will drive the two rotating rods 4 to rotate simultaneously. Both rotating rods 4 will drive the driving gear 10 and the fixed gear 8 to rotate. When the fixed gear 8 rotates, it will push the tooth block 74 upward. The tooth block 74 will drive the annular plate 73 to move upward. The upward movement of the annular plate 73 will drive the round rod 71 and the integrated baffle 72 to move together. The rotation of the rotating ring 5 causes the fixed spring 75 to compress and contract. The presence of the toothed block 74 and the fixed spring 75 provides stability for the rotation of the rotating ring 5. When rotating the rotating ring 5, force is required to move the annular plate 73 upward. When the driving gear 10 rotates, it will drive another driving gear 10 and the connecting rod 9 to rotate. At this time, all driving gears 10 are in a rotating state. The driving gear 10 will drive the driven rack 15 to move upward. The driven rack 15 will drive the mounting rod 16 to move upward. The upward movement of the mounting rod 16 will drive the compression wheel. 17 moves upward, thus pressing against the pressure seat 144. The pressed pressure seat 144 will drive the abutment rod 142 to move towards the earphone. The movement of the abutment rod 142 is guided by the limit rod 141. At the same time, the movement of the abutment rod 142 will stretch the abutment spring 143. At this time, the moving abutment rod 142 will drive the abutment ring 145 to abut against the side of the earphone. At this time, the earphone will not loosen or shift due to the abutment of the abutment ring 145. Meanwhile, when the driven rack 15 moves upward, it will drive the driven gear 182 to rotate. The rotation of 182 will drive the transmission rod 181 and the clamping rod 183 to rotate. At this time, each clamping rod 183 will rotate towards the position of the elastic strap 19. The clamping rod 183 will drive the clamping block 184 to rotate together. The rotating clamping block 184 will clamp the elastic strap 19 near the top. As the clamping rod 183 and the clamping block 184 continue to rotate, the clamping block 184 will gather the top of the elastic strap 19 together. At this time, the elastic strap 19 will change from a U-shape to a ring. The ring-shaped elastic strap 19 will encircle the user's ears.
