[0002] In the current technology, audio equipment is generally produced and processed in an assembly line manner, in which the assembly of many parts is mostly done manually. During the assembly process, workers directly place the speaker base on the workbench to perform assembly work. However, this method of directly placing the speaker base on the workbench can cause the speaker base to slide on the workbench during the assembly of parts, which reduces work efficiency. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the easy sliding of speaker bases, and to propose a clamping device for speaker assembly.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a clamping device, comprising a housing, wherein an adjusting device is provided inside the housing, the adjusting device comprising two fixing blocks, the two fixing blocks being fixedly connected to the lower side of the housing interior, an adjusting rod being slidably connected inside the fixing blocks, a connecting strip being fixedly connected to one end of the adjusting rod, two sliding holes being formed on the surface of the housing, the connecting strip being slidably connected to the inner wall of the sliding holes, a clamping plate being fixedly connected to the side of the connecting strip away from the adjusting rod, a pulley being fixedly connected to the end of the adjusting rod away from the connecting strip, and a spring being fitted onto the arc surface of the adjusting rod, the two ends of the spring being respectively connected to the fixed plate. A fixed block and a pulley are fixedly connected. An auxiliary block is slidably connected to the arc surface of the pulley. A connecting rod is fixedly connected to one side of the auxiliary block. An adjusting block is fixedly connected to the lower surface of the connecting rod. An adjusting groove is opened on the lower side of the inside of the housing. The adjusting block is slidably connected to the inner wall of the adjusting groove. A handle is fixedly connected to the side of the connecting rod away from the adjusting block. An adjusting hole is opened on the upper side of the housing. The handle is slidably connected to the inner wall of the adjusting hole. An adjusting plate is fixedly connected to the upper surface of the housing. Several round holes are opened inside the adjusting plate. A pin is slidably connected to the inner wall of the round holes of the adjusting plate. The pin passes through the adjusting plate and engages with the handle.
[0005] The aforementioned components achieve the following effect: by pushing or pulling the lever, the two clamps on the cabinet can simultaneously clamp and release the speaker base, and the lever is then limited by a pin, making the operation simple and quick.
[0006] Preferably, an anti-slip pad is fixedly connected to the side of the clamp away from the connecting strip, and a number of anti-slip patterns are evenly distributed on one side of the anti-slip pad.
[0007] The effect achieved by the above components is to increase the friction between the clamp and the speaker base, thereby improving stability.
[0008] Preferably, a screw is threadedly inserted into the upper surface of the housing, and a support plate is rotatably connected to the upper end of the screw.
[0009] The effect achieved by the above components is to adjust the height of the support plate relative to the height of the clamping plate according to the dimensions of both sides of the speaker base, so that the clamping plate can clamp the speaker base tightly.
[0010] Preferably, an auxiliary device is provided below the box body. The auxiliary device includes a support block, which is fixedly connected to the lower surface of the box body. Four support rods are rotatably connected to both sides of the support block. The four support rods are arranged in pairs. A limit block is rotatably connected to the end of each pair of support rods away from the support block. An auxiliary rod is threadedly connected to the inside of the limit block. A support plate is rotatably connected to the arc surface of the auxiliary rod. A limit groove is formed inside the support plate. The inner wall of the limit groove is slidably connected to the limit block. A handle is fixedly connected to one end of the auxiliary rod.
[0011] The effect achieved by the above components is that the height of the box can be adjusted by rotating the handles on both sides of the support plate, and the appropriate height can improve the user's comfort during operation.
[0012] Preferably, the arc surface of the handle is fixedly connected with a plurality of protrusions, which are evenly distributed on the arc surface of the handle.
[0013] The effect achieved by the above components is to increase the friction of the handle's arc surface, making it easier for the user to rotate.
[0014] Preferably, the inner wall of the limiting groove is connected to an auxiliary groove, and two blocks are fixedly connected to both sides of the limiting block, with the two blocks slidably connected to the inner wall of the auxiliary groove.
[0015] The effect achieved by the above components is that the auxiliary groove further limits the position of the limiting block.
[0016] In summary, the beneficial effects of this utility model are as follows: In this invention, when the speaker base needs to be clamped during assembly, the dimensions of the speaker base's sides and clamping plate are first observed using the adjustment device. The support plate is then rotated, causing the bottom screw to rotate. The screw moves upward or downward via the thread. After the support plate is adjusted to a suitable height, the speaker base is placed on the support plate. Then, the pin connecting the adjustment plate and the handle is removed, and the handle is pulled towards the support plate. The handle slides along the adjustment groove towards the support plate via the adjustment block on the lower surface of the connecting rod. Simultaneously, the handle, through the connecting rod, drives the auxiliary block within the housing. The auxiliary block moves inward toward the pulley, and the curved surface of the auxiliary block squeezes the pulley during the movement. The squeezed pulley causes the adjusting rod to slide along the inner wall of the auxiliary block toward the support plate. The adjusting rod drives the connecting strip and clamping plate to move toward the speaker base, where the spring is compressed. After the anti-slip pad on the clamping plate contacts and clamps the speaker base, the pin is passed through the preset round hole on the adjusting rod and engages with the handle to limit the handle. The speaker is then clamped, which solves the problem of the speaker base sliding on the worktable during the assembly of speaker base components, thus reducing work efficiency.
[0017] In this invention, with the aid of an auxiliary device, when the speaker base is clamped during assembly and the height of the speaker base on the support plate is inconvenient for the user, the two handles on both sides of the support plate are rotated first. The handles drive the auxiliary rod inside the support plate to rotate. At this time, the limiting block on the arc surface of the auxiliary rod moves away from the handle along the auxiliary rod and the limiting groove with the help of the thread. At this time, the support rod connected between the support block and the limiting block rotates and arches upward to support the support block. The support block drives the cabinet and speaker base to move upward. The auxiliary groove further limits the limiting block. Continue to rotate the handle until the speaker base is raised to the ideal height, which meets the needs of users of different heights for the placement height of the speaker base and improves the comfort of the user during operation.

[0020] Reference Figure 1 As shown, this utility model provides a technical solution: a clamping device for audio assembly, including a housing 1, an adjustment device 2 inside the housing 1, and an auxiliary device 3 below the housing 1.
[0021] The specific settings and functions of its adjustment device 2 and auxiliary device 3 will be described in detail below.
[0022] Reference Figures 2 to 3As shown in this embodiment: the adjusting device 2 includes two fixing blocks 201, which are fixedly connected to the lower side of the inside of the housing 1. An adjusting rod 202 is slidably connected inside the fixing blocks 201. A connecting strip 205 is fixedly connected to one end of the adjusting rod 202. Two sliding holes are opened on the surface of the housing 1. The connecting strip 205 is slidably connected to the inner wall of the sliding holes. A clamping plate 206 is fixedly connected to the side of the connecting strip 205 away from the adjusting rod 202. A sliding plate 206 is fixedly connected to the end of the adjusting rod 202 away from the connecting strip 205. A spring 203 is fitted onto the arc surface of the pulley 204 and the adjusting rod 202. The two ends of the spring 203 are fixedly connected to the fixed block 201 and the pulley 204, respectively. An auxiliary block 208 is slidably connected to the arc surface of the pulley 204. A connecting rod 209 is fixedly connected to one side of the auxiliary block 208. An adjusting block 210 is fixedly connected to the lower surface of the connecting rod 209. An adjusting groove 211 is provided on the lower side of the interior of the housing 1. The adjusting block 210 is slidably connected to the inner wall of the adjusting groove 211. The side of the connecting rod 209 away from the adjusting block 210 is fixedly connected to the inner wall of the adjusting groove 211. A handle 212 is fixedly connected to the upper side of the cabinet 1. An adjustment hole is provided on the upper side of the cabinet 1. The handle 212 is slidably connected to the inner wall of the adjustment hole. An adjustment plate 213 is fixedly connected to the upper surface of the cabinet 1. Several round holes are provided inside the adjustment plate 213. A pin 214 is slidably connected to the inner wall of the round holes of the adjustment plate 213. The pin 214 passes through the adjustment plate 213 and engages with the handle 212. By pushing and pulling the handle 212, the two clamping plates 206 on the cabinet 1 can simultaneously clamp and loosen the speaker base. The handle 212 is then engaged with the upper side of the cabinet 1 by the pin 214. 2. Limiting is performed, and the operation is simple and quick. The side of the clamping plate 206 away from the connecting strip 205 is fixedly connected to the anti-slip pad 207. The anti-slip pad 207 has several anti-slip patterns evenly distributed on one side to increase the friction when the clamping plate 206 contacts the speaker base and improve stability. The upper surface of the cabinet 1 is threaded with a screw 215. The upper end of the screw 215 is rotatably connected to the support plate 216. According to the size of the two sides of the speaker base, the height of the support plate 216 relative to the height of the clamping plate 206 can be adjusted to facilitate the clamping plate 206 to clamp the speaker base.
[0023] Reference Figure 4As shown in this embodiment: the auxiliary device 3 includes a support block 31, which is fixedly connected to the lower surface of the housing 1. Four support rods 32 are rotatably connected to both sides of the support block 31. The four support rods 32 are grouped in pairs. A limit block 33 is rotatably connected to the end of each group of support rods 32 away from the support block 31. An auxiliary rod 34 is threadedly connected to the inside of the limit block 33. A support plate 36 is rotatably connected to the arc surface of the auxiliary rod 34. A limit groove 37 is formed inside the support plate 36. The inner wall of the limit groove 37 is slidably connected to the limit block 33. One end of the auxiliary rod 34 is fixedly connected to the limit block 33. The handle 35 is fixedly connected. The height of the box 1 can be adjusted by rotating the handles 35 on both sides of the support plate 36. The appropriate height can improve the comfort of the user during operation. Several protrusions are fixedly connected to the arc surface of the handle 35. The protrusions are evenly distributed on the arc surface of the handle 35 to increase the friction of the arc surface of the handle 35 and facilitate the user's rotation. The inner wall of the limiting groove 37 is connected to the auxiliary groove 38. Two square blocks are fixedly connected to both sides of the limiting block 33. The two square blocks are slidably connected to the inner wall of the auxiliary groove 38. The auxiliary groove 38 plays a further limiting role for the limiting block 33.
[0024] Working principle: When clamping the speaker base during assembly, first observe the dimensions of the speaker base's sides and clamping plate 206 using the adjustment device 2. Rotate the support plate 216, which drives the bottom screw 215 to rotate. The screw 215 moves up or down via the thread. After adjusting the support plate 216 to the appropriate height, place the speaker base on the support plate 216. Then, remove the pin 214 connecting the adjustment plate 213 and the handle 212, and pull the handle 212 towards the support plate 216. The handle 212 slides along the adjustment groove 211 towards the support plate 216 via the adjustment block 210 on the lower surface of the connecting rod 209. At this time, the handle 212 drives the auxiliary block 208 via the connecting rod 209. The device moves within housing 1 towards pulley 204. During this movement, the curved surface of auxiliary block 208 presses against pulley 204, causing adjusting rod 202 to slide along the inner wall of auxiliary block 208 towards support plate 216. Adjusting rod 202 drives connecting bar 205 and clamping plate 206 towards speaker base, with spring 203 in a compressed state. Once the anti-slip pad 207 on clamping plate 206 contacts and clamps the speaker base, pin 214 is passed through a pre-set round hole on adjusting rod 202 and engages with handle 212, limiting handle 212. The speaker is then clamped, solving the problem of speaker base sliding on the worktable and reducing work efficiency during component assembly.
[0025] With the auxiliary device 3, when the high-fidelity speaker base is clamped during assembly and the height of the speaker base on the support plate 216 is inconvenient for the user, the two handles 35 on both sides of the support plate 36 are rotated first. The handles 35 drive the auxiliary rod 34 inside the support plate 36 to rotate. At this time, the limiting block 33 on the arc surface of the auxiliary rod 34 moves away from the handle 35 along the auxiliary rod 34 and the limiting groove 37 by means of the thread. At this time, the support rod 32 connected between the support block 31 and the limiting block 33 rotates and arches upward to support the support block 31. The support block 31 drives the cabinet 1 and the speaker base to move upward. The auxiliary groove 38 further limits the limiting block 33. Continue to rotate the handle 35 until the speaker base is raised to the ideal height, which meets the needs of users of different heights for the placement height of the speaker base and improves the comfort of the user during operation.
