Description

Technical Field

[0001] This utility model relates to the field of audio testing technology, and in particular to an audio testing fixture with a protective structure. Background Technology

[0002] With the continuous development and upgrading of electronic products, the demand for test fixtures is also increasing. Audio test fixtures, as an important tool in electronic product testing, directly affect the accuracy and reliability of test results due to their quality and performance. Therefore, it is necessary to design an audio test fixture with a protective structure.

[0003] To address this, patent CN218785487U discloses an audio testing positioning fixture, including a testing device body with a clamping assembly. The clamping assembly includes a limiting plate with a reciprocating groove inside. A reciprocating block is slidably connected inside the reciprocating groove. The audio testing positioning fixture provided by this invention, by pulling a positioning rod, prevents the positioning rod from limiting the first clamping plate. Then, the first clamping plate is pushed to one side of the limiting plate, and the device to be tested is placed on one side of the limiting plate. A push spring then pushes the reciprocating block, causing the reciprocating block to clamp and fix the first clamping plate. Furthermore, after the first clamping plate moves, the positioning rod, in conjunction with the positioning groove, positions the moved first clamping plate, thereby improving the stability of fixing the testing device and avoiding the problems of existing positioning fixtures being complex and inconvenient for positioning different devices.

[0004] While the audio test positioning fixtures described above can improve the stability of the test equipment during use, it is inconvenient to change different clamping components according to the shape of different equipment when fixing the test equipment. Therefore, it is necessary to design an audio test fixture with a protective structure. Utility Model Content

[0005] The purpose of this invention is to provide an audio test fixture with a protective structure to solve the problem that existing audio test fixtures are inconvenient to replace different clamping components according to the shape of different equipment when fixing test equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an audio test fixture with a protective structure, including a base;

[0007] Clamping components are fixed on both sides of the top of the base, and auxiliary structures are provided at both ends of the clamping components. A clamping plate is provided on one side of the clamping components.

[0008] The clamping plate has a disassembly structure evenly fixed on the outer wall of the side near the clamping assembly. The disassembly structure includes a connecting block, a connecting groove, a reinforcing spring, a sliding rod, a slider, and a limiting block. The connecting blocks are evenly arranged on the outer wall of one side of the clamping plate. A connecting groove is opened on one side of each connecting block. A slider is arranged inside the connecting groove. A reinforcing spring is fixed between adjacent sliders. A sliding rod is slidably connected inside each slider. A limiting block is fixed on the outer wall of the connecting block away from the slider.

[0009] A protective component is fixed to the top of the base.

[0010] Furthermore, the clamping assembly includes a rotating shaft, a threaded sleeve, a mounting plate, a mounting base, a mounting groove, and a guide rod. The mounting plates are all fixed to both sides of the top of the base. The rotating shaft passes through the interior of each mounting plate. Threaded sleeves are fixed to the outer walls of the mounting plates outside the rotating shaft. A mounting base is fixed to the end of the rotating shaft away from the threaded sleeve. A mounting groove is opened inside each mounting base. Guide rods are provided on both sides of the rotating shaft.

[0011] Furthermore, the rotating shaft and the threaded sleeve are threadedly connected, and one end of the rotating shaft is rotatably connected to the mounting base.

[0012] Furthermore, the guide rod and the mounting plate are slidably connected, and the guide rod is symmetrically distributed on both sides of the rotation axis.

[0013] Furthermore, the auxiliary structure includes a pressing plate, a pressing shaft, a return spring, and an auxiliary plate. The pressing shaft is slidably connected to both sides inside the mounting base. The pressing plate is fixed to the end of the pressing shaft away from the mounting base. The return spring is located on the outside of the pressing shaft. One end of the pressing shaft extends into the interior of the mounting groove and is fixed with an auxiliary plate.

[0014] Furthermore, the pressing plate and the pressing shaft form a telescopic structure through a reset spring, and the auxiliary plates are symmetrically distributed on both sides of the mounting groove.

[0015] Furthermore, the limiting block and the mounting base form an engaging structure through the mounting groove, and the limiting block is symmetrically distributed on both sides of the mounting groove.

[0016] Furthermore, the protective component includes a protective plate, an adhesive layer, and a protective sponge. The protective plate is fixed to the top of the base, the adhesive layer is fixed to the inner wall of the bottom of the protective plate, and the protective sponge is fixed to the top of the adhesive layer.

[0017] The present invention provides an audio test fixture with a protective structure, the advantages of which are:

[0018] With a detachable structure, the clamping plate can be dragged outwards by hand. Under the action of force, the limiting block will cause the connecting block to deform inwards, making it easy to remove the limiting block from the inside of the mounting slot. The two ends of the reinforcing spring are fixedly connected to the slider. The reinforcing spring can strengthen the connecting block through the slider, preventing the connecting block from easily deforming inwards. This can prevent the clamping plate from knocking the connecting block and the limiting block out of the mounting slot when it is hit, increasing the stability of the clamping plate installation. This device has the function of easy installation and removal of the clamping plate, improving the convenience and work efficiency of the audio test fixture during use.

[0019] By setting up an auxiliary structure, when it is inconvenient to remove the limiting block and connecting block by dragging the clamping plate, pressing the pressing plate will cause the pressing plate to drive the auxiliary plate and the limiting block to squeeze through the pressing shaft. The limiting block assists in the inward deformation of the connecting block, thus realizing the function of facilitating disassembly of the device and improving the convenience of the audio test fixture in use.

[0020] By incorporating a clamping assembly, rotating the rotating shaft causes the mounting base to move closer together, facilitating the clamping of the workpiece to be tested. This enables the device to easily clamp the workpiece and improves the convenience of using the audio test fixture. Attached Figure Description

Detailed Implementation

[0027] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 The present invention provides an audio test fixture with a protective structure, including a base 1.

[0029] Reference Figures 1-5 Both sides of the top of the base 1 are fixed with clamping components 2. The clamping components 2 include a rotating shaft 21, a threaded sleeve 22, a mounting plate 23, a mounting base 24, a mounting groove 25, and a guide rod 26. The mounting plates 23 are fixed to both sides of the top of the base 1. The rotating shaft 21 passes through the interior of each mounting plate 23. Threaded sleeves 22 are fixed to the outer walls of the mounting plates 23 outside the rotating shaft 21. A mounting base 24 is fixed to the end of the rotating shaft 21 away from the threaded sleeve 22. The mounting base 24 has a mounting groove 25 inside. The two sides of the rotating shaft 21 Guide rods 26 are provided on both sides, and a rotating shaft 21 and a threaded sleeve 22 are threadedly connected. One end of the rotating shaft 21 is rotatably connected to the mounting base 24. The guide rods 26 and the mounting plate 23 are slidably connected. The guide rods 26 are symmetrically distributed on both sides of the rotating shaft 21. A protective component 6 is fixed to the top of the base 1. The protective component 6 includes a protective plate 61, an adhesive layer 62 and a protective sponge 63. The protective plate 61 is fixed to the top of the base 1. An adhesive layer 62 is fixed to the inner wall of the bottom of the protective plate 61. A protective sponge 63 is fixed to the top of the adhesive layer 62.

[0030] Rotate the rotating shaft 21. When the rotating shaft 21 rotates, it will move inside the threaded sleeve 22. The movement of the rotating shaft 21 will drive the mounting base 24 to move. The mounting bases 24 move closer to each other, which can facilitate the clamping of the workpiece to be tested.

[0031] Reference Figures 1-4 Both ends of the clamping assembly 2 are provided with auxiliary structures 3. The auxiliary structures 3 include pressing plates 31, pressing shafts 32, return springs 33 and auxiliary plates 34. The pressing shafts 32 are slidably connected to both sides inside the mounting base 24. The pressing plates 31 are fixed to the ends of the pressing shafts 32 away from the mounting base 24. The return springs 33 are provided on the outside of the pressing shafts 32. One end of the pressing shafts 32 extends into the interior of the mounting groove 25 and is fixed with the auxiliary plates 34. The pressing plates 31 and the pressing shafts 32 form a telescopic structure through the return springs 33. The auxiliary plates 34 are symmetrically distributed on both sides of the mounting groove 25.

[0032] When the clamping plate 4 is being pulled to disassemble or assemble, if the connecting block 51 is difficult to deform under the reinforcing action of the reinforcing spring 53, and it is inconvenient to remove the limiting block 56 and the connecting block 51, press the pressing plate 31. The pressing plate 31 will drive the auxiliary plate 34 and the limiting block 56 to squeeze through the pressing shaft 32, and the limiting block 56 will assist the connecting block 51 to deform inward.

[0033] Reference Figures 2-5 A clamping plate 4 is provided on one side of the clamping assembly 2. A disassembly structure 5 is evenly fixed on the outer wall of the clamping plate 4 near the clamping assembly 2. The disassembly structure 5 includes a connecting block 51, a connecting groove 52, a reinforcing spring 53, a sliding rod 54, a slider 55, and a limiting block 56. The connecting blocks 51 are evenly arranged on the outer wall of one side of the clamping plate 4. A connecting groove 52 is opened on one side of the connecting block 51. A slider 55 is provided inside the connecting groove 52. A reinforcing spring 53 is fixed between adjacent sliders 55. A sliding rod 54 is slidably connected inside the slider 55. A limiting block 56 is fixed on the outer wall of the connecting block 51 away from the slider 55. The limiting block 56 and the mounting base 24 form a locking structure through the mounting groove 25. The limiting blocks 56 are symmetrically distributed on both sides of the mounting groove 25.

[0034] When the clamping plate 4 needs to be replaced, hold the clamping plate 4 and drag it outward. At this time, the limiting block 56 and the inner wall of the mounting base 24 abut against each other. Under the action of force, the limiting block 56 will drive the connecting block 51 to deform inward, which makes it easier to remove the limiting block 56 from the inside of the mounting groove 25. The two ends of the reinforcing spring 53 are fixedly connected to the slider 55. The reinforcing spring 53 can strengthen the connecting block 51 through the slider 55, preventing the connecting block 51 from easily deforming inward. This can prevent the clamping plate 4 from knocking the connecting block 51 and the limiting block 56 out of the inside of the mounting groove 25 when it is hit, thus increasing the stability of the clamping plate 4 installation.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
