[0004] The inventors discovered during daily use that after prolonged use of the hearing amplifier, wear would occur at the connection between the slot and the data transmission head, which would lead to a loose connection between the slot and the data transmission head. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where wear occurs at the connection between the slot and the data transmission head after prolonged use of the hearing amplifier, leading to loosening of the connection. This invention provides a portable hearing amplifier.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a hearing amplifier body, the inner wall of which is fitted with a slot. A data transmission head is slidably connected to the inner wall of the slot. An auxiliary structure is provided on the side of the hearing amplifier body near the data transmission head. The auxiliary structure includes two positioning blocks, two fixing blocks, and a fixing plate. The two positioning blocks are fixedly connected to the data transmission head, the two fixing blocks are fixedly connected to the hearing amplifier body, and the fixing plate is fixedly connected to the hearing amplifier body. An auxiliary groove is formed on the inner wall of each fixing block. A moving block is slidably connected to the inner wall of the auxiliary groove. A positioning rod is fixedly connected to the inner wall of the auxiliary groove, and the positioning rod is slidably connected to the moving block. A first spring is provided between the side of the block away from the data transmission head and the auxiliary slot. The two ends of the first spring are fixedly connected to the auxiliary slot and the moving block, respectively. A connecting block is fixedly connected to the side of the moving block away from the hearing amplifier body. A locking block is fixedly connected to the side of the connecting block near the positioning block. The locking block is slidably connected to the positioning block. A connecting slot is provided on the inner wall of the fixed plate. An adjusting plate is slidably connected to the inner wall of the connecting slot. A second spring is provided between the lower surface of the adjusting plate and the connecting slot. The two ends of the second spring are fixedly connected to the adjusting plate and the connecting slot, respectively. An auxiliary plate is fixedly connected to the side of the adjusting plate away from the hearing amplifier body. Two top plates are fixedly connected to the lower surface of the auxiliary plate. The top plates are slidably connected to the fixed plate.

[0007] The effect achieved by the above-mentioned components is as follows: When using the hearing amplifier, the user hangs the amplifier on their waist or holds it in their hand, and then inserts the data transmission head into the inner wall of the slot. After long-term use, wear may occur at the connection between the slot and the data transmission head, causing the data transmission head to become loose. This problem can be solved by the auxiliary structure. When the user inserts the data transmission head into the slot, the auxiliary structure can limit the data transmission head, thereby improving the stability of the data transmission head during data transmission.

[0008] Preferably, the inner wall of the auxiliary plate is provided with a plurality of anti-slip grooves, which are evenly distributed on the auxiliary plate.

[0009] The effect achieved by the above components is that the anti-slip groove can increase the friction between the personnel's hands and the auxiliary plate, and can prevent the personnel from slipping when moving the auxiliary plate.

[0010] Preferably, a limiting rod is fixedly connected to the inner wall of the connecting groove, and the limiting rod is slidably connected to the adjusting plate.

[0011] The effect achieved by the above components is that the limiting rod can limit the adjustment plate and prevent the adjustment plate from slipping during the sliding process on the inner wall of the connecting groove.

[0012] Preferably, the top plate is made of stainless steel and is trapezoidal in shape.

[0013] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the top plate from deforming during short-term use.

[0014] Preferably, a limiting structure is provided on one side of the hearing amplifier body. The limiting structure includes a connecting plate and a welding plate. The connecting plate is fixedly connected to the hearing amplifier body, and the welding plate is fixedly connected to the hearing amplifier body. A rotating rod is rotatably connected to the inner wall of the connecting plate. An elastic band is fixedly connected to the arc surface of the rotating rod. An insert plate is fixedly connected to the end of the elastic band away from the rotating rod. A connecting post is fixedly connected to the inner wall of the welding plate. A rotating plate is rotatably connected to the arc surface of the connecting post. A connecting groove and a slot are provided on the inner wall of the rotating plate. The connecting groove and the slot are interconnected. A pressing plate is slidably connected to the inner wall of the connecting groove. Two third springs are provided between the side of the pressing plate near the hearing amplifier body and the connecting groove. The two ends of the third springs are fixedly connected to the pressing plate and the connecting groove, respectively. The insert plate is slidably connected to the connecting groove and abuts against the pressing plate. A positioning plate is slidably connected to the inner wall of the slot. The positioning plate is fixedly connected to the insert plate.

[0015] The effect achieved by the above components is as follows: when a person needs to hold the hearing amplifier body for use, the person can move the insert plate through the limiting structure. The insert plate drives the elastic band to move, causing the positioning plate to slide into the inner wall of the slot. At this time, the elastic band will fit against the back of the person's hand, thereby preventing the person from slipping and causing the hearing amplifier body to fall to the ground during use.

[0016] Preferably, the arc surface of the connecting column is fitted with two coil springs, and the two ends of the coil springs are fixedly connected to the rotating plate and the welding plate, respectively.

[0017] The effect achieved by the above components is that the coil spring can limit the rotation plate, preventing it from rotating on its own when it is not in use.

[0018] Preferably, a pressing plate is fixedly connected to the side of the extrusion plate away from the hearing amplifier body, and the pressing plate is slidably connected to the rotating plate.

[0019] The effect achieved by the above components is that the pressing plate allows personnel to easily move the squeezing plate, which can improve the ease of operation for personnel.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, by operating the auxiliary structure, when the connection between the data transmission head and the slot of the hearing amplifier body becomes loose after prolonged use, the auxiliary structure can limit the data transmission head, preventing data transmission interruption due to loose connection between the data transmission head and the slot during use of the hearing amplifier body, thereby improving the stability of data transmission.

[0022] In this invention, by operating the limiting structure, when a person needs to hold the hearing amplifier body for use, the limiting structure can limit the person's hand, thereby preventing the hearing amplifier body from slipping and falling to the ground during use.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0031] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a portable hearing amplifier, including a hearing amplifier body 1, a slot 5 installed on the inner wall of the hearing amplifier body 1, a data transmission head 2 slidably connected to the inner wall of the slot 5, an auxiliary structure 3 provided on the side of the hearing amplifier body 1 near the data transmission head 2, and a limiting structure 4 provided on one side of the hearing amplifier body 1.

[0032] The specific settings and functions of its auxiliary structure 3 and limiting structure 4 will be discussed below.

[0033] Reference Figure 3 and Figure 4As shown in this embodiment: the auxiliary structure 3 includes two positioning blocks 303, two fixing blocks 301, and a fixing plate 302. The two positioning blocks 303 are fixedly connected to the data transmission head 2, the two fixing blocks 301 are fixedly connected to the hearing amplifier body 1, and the fixing plate 302 is fixedly connected to the hearing amplifier body 1. An auxiliary groove 305 is provided on the inner wall of the fixing block 301. A moving block 308 is slidably connected to the inner wall of the auxiliary groove 305. A positioning rod 306 is fixedly connected to the inner wall of the auxiliary groove 305. The positioning rod 306 is slidably connected to the moving block 308. A first spring 307 is provided between the side of the moving block 308 away from the data transmission head 2 and the auxiliary groove 305. The two ends of the first spring 307 are fixedly connected to the auxiliary groove 305 and the moving block 308, respectively. Next, a connecting block 309 is fixedly connected to the side of the movable block 308 away from the hearing amplifier body 1. A locking block 304 is fixedly connected to the side of the connecting block 309 near the positioning block 303. The locking block 304 is slidably connected to the positioning block 303. A connecting groove 311 is provided on the inner wall of the fixed plate 302. An adjusting plate 314 is slidably connected to the inner wall of the connecting groove 311. A second spring 312 is provided between the lower surface of the adjusting plate 314 and the connecting groove 311. The two ends of the second spring 312 are fixedly connected to the adjusting plate 314 and the connecting groove 311, respectively. An auxiliary plate 310 is fixedly connected to the side of the adjusting plate 314 away from the hearing amplifier body 1. Two top plates 316 are fixedly connected to the lower surface of the auxiliary plate 310. The top plates 316 are slidably connected to the fixed plate 302. When using the hearing amplifier body 1, the user hangs it on their waist or holds it in their hand, then inserts the data transmission head 2 into the inner wall of the slot 5. Over time, wear and tear can occur at the connection between the slot 5 and the data transmission head 2, causing the data transmission head 2 to loosen. This problem can be solved by the auxiliary structure 3. When the user inserts the data transmission head 2 into the slot 5, the auxiliary structure 3 can limit its movement, thus improving the stability of the data transmission head 2 during data transmission. The inner wall of the auxiliary plate 310 has several anti-slip grooves 315, evenly distributed on the auxiliary plate 310. The anti-slip grooves 315 increase the friction between the user's hand and the auxiliary plate 310, preventing slippage during movement. A limiting rod 313 is fixedly connected to the inner wall of the connecting groove 311, and the limiting rod 313 is slidably connected to the adjusting plate 314. The limiting rod 313 can limit the adjustment plate 314, preventing it from slipping during sliding on the inner wall of the connecting groove 311. The top plate 316 is made of stainless steel and is trapezoidal in shape. Stainless steel has high strength and good wear resistance, which can prevent the top plate 316 from deforming during short-term use.

[0034] Reference Figure 5 and Figure 6As shown in this embodiment: the limiting structure 4 includes a connecting plate 401 and a welding plate 404. The connecting plate 401 is fixedly connected to the hearing amplifier body 1, and the welding plate 404 is fixedly connected to the hearing amplifier body 1. A rotating rod 402 is rotatably connected to the inner wall of the connecting plate 401. An elastic band 403 is fixedly connected to the arc surface of the rotating rod 402. An insert plate 408 is fixedly connected to the end of the elastic band 403 away from the rotating rod 402. A connecting post 405 is fixedly connected to the inner wall of the welding plate 404. A rotating plate 406 is rotatably connected to the arc surface of the connecting post 405. The inner wall of the rotating plate 406 has an opening... The connecting groove 410 and the slot 412 are interconnected. The inner wall of the connecting groove 410 is slidably connected to the extrusion plate 409. Two third springs 407 are provided between the side of the extrusion plate 409 near the hearing amplifier body 1 and the connecting groove 410. The two ends of the third springs 407 are fixedly connected to the extrusion plate 409 and the connecting groove 410 respectively. The insertion plate 408 is slidably connected to the connecting groove 410 and abuts against the extrusion plate 409. The inner wall of the slot 412 is slidably connected to the positioning plate 411 and is fixedly connected to the insertion plate 408. When a person needs to hold the hearing amplifier body 1 for use, the limiting structure 4 allows the person to move the insert plate 408. The insert plate 408 moves the elastic band 403, causing the positioning plate 411 to slide into the inner wall of the slot 412. At this time, the elastic band 403 will fit against the back of the person's hand, thus preventing the hearing amplifier body 1 from slipping and falling to the ground during use. The arc surface of the connecting column 405 is fitted with two coil springs 414, and the two ends of the coil springs 414 are fixedly connected to the rotating plate 406 and the welding plate 404, respectively. The coil springs 414 can limit the rotating plate 406, preventing the rotating plate 406 from rotating on its own when the person does not need to use it. The pressing plate 413 is fixedly connected to the side of the pressing plate 409 away from the hearing amplifier body 1, and the pressing plate 413 is slidably connected to the rotating plate 406. The pressing plate 413 allows personnel to easily move the pressing plate 409, improving the ease of operation.

[0035] Detailed Instructions for Use: When the data transmission head 2 is inserted into the slot 5, the data transmission head 2 will move the two positioning blocks 303 closer to the slot 5. During this movement, the two positioning blocks 303 will abut against the locking block 304, causing the locking block 304 to move away from the data transmission head 2. The locking block 304 will then move the connecting block 309 away from the data transmission head 2, which in turn will move the moving block 308 away from the data transmission head 2. The moving block 308 will then cause the first spring 307 to retract until the data connection part of the data transmission head 2 is completely slid into the inner wall of the slot 5. At this point, the first spring 307 will rebound, causing the locking block 304 to slide into the inner wall of the positioning block 303. When the user needs to remove the data transmission head 2, they can first move the auxiliary plate 310 closer to the data transmission head. The auxiliary plate 310 moves in the direction of 2. The anti-slip groove 315 on the inner wall of the auxiliary plate 310 increases the friction between the personnel's hands and the auxiliary plate 310, preventing the personnel from slipping during the movement of the auxiliary plate 310. Then, the auxiliary plate 310 drives the two top plates 316 and the adjusting plate 314 to move closer to the data transmission head 2. The stainless steel plate of the top plate 316 has high strength and good wear resistance, which can prevent the top plate 316 from deforming during short-term use. Then, the adjusting plate 314 slides on the arc surface of the limiting rod 313. The limiting rod 313 can limit the adjusting plate 314, preventing the adjusting plate 314 from slipping during the sliding of the inner wall of the connecting groove 311. The adjusting plate 314 also drives the second spring 312 to retract. The two top plates 316 respectively drive the connecting block 309 to move away from the positioning block 303 until the locking block 304 slides out of the inner wall of the positioning block 303.

[0036] Additionally, when a person needs to hold the hearing amplifier body 1 for use, they can first hold the hearing amplifier body 1, and then move the insert plate 408. The insert plate 408 drives one end of the elastic band 403 and the positioning plate 411 to move closer to the rotating plate 406. As the elastic band 403 moves closer to the rotating plate 406, it drives the rotating rod 402 to rotate until the insert plate 408 slides into the inner wall of the connecting groove 410. During the sliding process of the insert plate 408 in the inner wall of the connecting groove 410, the insert plate 408 will abut against the pressing plate 409, and then drive the pressing plate 409 to move closer to the hearing amplifier body 1. The two third springs 407 are wound up, and the pressing plate 409 also drives the pressing plate 413 to move closer to the hearing amplifier body 1. The pressing plate 413 makes it easy for the operator to move the pressing plate 409, which can improve the operator's ease of operation. Until the positioning plate 411 corresponds to the slot 412, the two third springs 407 rebound and make the positioning plate 411 slide into the inner wall of the slot 412. At this time, the elastic band 403 is in contact with the back of the operator's hand. The two coil springs 414 on the arc surface of the connecting column 405 can limit the rotation plate 406, which can prevent the rotation plate 406 from rotating on its own when the operator does not need to use it.
