DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 A test fixture with a protective function comprises a fixture body 1 and a support mechanism 2 arranged below the fixture body, and a second electric push rod 3 is fixedly connected to the left and right sides of the bottom of the support mechanism 2:

[0024] Furthermore, the fixture body 1 includes a mounting seat 101 correspondingly arranged on the left and right sides, and a positioning sleeve 102 is fixedly connected to the front and rear sides of the top of the mounting seat 101, and a clamping rod 104 is slidably connected inside the positioning sleeve 102. The bottom of the clamping rod 104 is slidably connected to the top of the test plate, and the clamping rod 104 is fixedly connected to a connecting rod 105 on one side close to each other. The center of the connecting rod 105 is rotatably connected to a first electric push rod 106, and one end of the first electric push rod 106 is rotatably connected to the opposite side of the mounting seat 101, and a threaded sleeve 107 is fixedly connected to the rear side of the mounting seat 101.

[0025] By using the first electric push rod 106 and the second electric push rod 3 in coordination, precise positioning and clamping of the test board in the vertical direction can be achieved, ensuring that test boards of different thicknesses or sizes can be firmly and properly fixed. The use of the first electric push rod 106 and the second electric push rod 3 improves the accuracy and convenience of adjustment, and reduces the complexity and error of manual operation. The sliding connection design of the positioning sleeve 102 and the clamping rod 104, plus the sliding connection between the clamping rod 104 and the top of the test board, means that when fixing the test board, direct pressure and friction on the board surface can be reduced, thereby reducing the risk of damage. The configuration of the connecting rod 105 and the first electric push rod 106 further ensures uniform force throughout the entire fixing process, protecting the test board from unnecessary physical damage. This design embodies comprehensive protection of the test board, a high degree of adjustment flexibility, and a response to automation needs in a modern manufacturing environment. It is an ideal solution for high-precision and high-efficiency testing needs.

[0026] Furthermore, a slot 103 is formed on the opposite side of the positioning sleeve 102 , and the slot 103 is slidably connected to the connecting rod 105 .

[0027] The slot 103 opened on the opposite side of the positioning sleeve 102 allows the connecting rod 105 to slide freely within a certain range, which means that the fixture can adapt to test boards of different widths or layouts. This design increases the versatility of the fixture, allowing the same set of fixtures to be applied to test boards of various sizes and shapes, reducing the frequency and complexity of replacing or adjusting the fixture.

[0028] Furthermore, a rubber sleeve is provided on the surface of the clamping rod 104 .

[0029] The rubber sleeve can provide a soft contact surface, effectively preventing scratches or damage to the surface of the test board when clamping it. This is especially beneficial for electronic components or coatings with sensitive and easily scratched surfaces, protecting the integrity and functionality of the test board.

[0030] Furthermore, the support mechanism 2 includes a support plate 201 , which is disposed below the mounting seat 101 , and a workbench 202 is fixedly connected to the center of the top of the support plate 201 , and a top of the workbench 202 is slidably connected to the bottom of the clamping rod 104 .

[0031] The support plate 201 is located below the mounting base 101, providing a solid base support, helping to disperse the pressure and vibration that may be generated during the test process and ensuring the overall stability of the test platform. The sliding connection design between the workbench 202 and the bottom of the clamping rod 104 allows the test board to have a certain adjustment space in the vertical direction, which is convenient for fine-tuning according to the actual thickness of the test board or test requirements, ensuring that the test board can be placed flat and firmly, further improving the accuracy and reliability of the test.

[0032] Furthermore, a fixed rod 203 is fixedly connected to the top of the support plate 201, and a movable sleeve 204 is slidably sleeved on the left and right sides of the surface of the fixed rod 203, and the top of the movable sleeve 204 is rotatably connected to the mounting seat 101 through a buffer.

[0033] By sliding the movable sleeve 204 on the fixed rod 203, combined with the rotational connection between the slide rod 206 and the bottom of the mounting base 101, multi-dimensional fine-tuning of the position of the mounting base 101 is achieved, which not only enables the fixture to adapt to a wider variety of test board sizes and shapes, but also ensures the precise alignment of the test board with the test environment when loading.

[0034] Furthermore, the buffer member includes a fixed sleeve 205 rotatably arranged on the top of the movable sleeve 204, a slide rod 206 is slidably connected inside the fixed sleeve 205, the slide rod 206 is rotatably connected to the bottom of the mounting seat 101, and a spring 207 is fixedly connected between the fixed sleeve 205 and the slide rod 206.

[0035] When encountering external force impact during the test process or operation, the spring 207 can absorb and disperse these forces to protect the test board from damage and reduce the interference of vibration on the test results. It is particularly suitable for test environments that are sensitive to vibration.

[0036] Furthermore, mounting frames 208 are fixedly connected to the left and right ends of the rear side of the support plate 201 , a bidirectional threaded rod 209 is rotatably connected between the mounting frames 208 , one end of the bidirectional threaded rod 209 is fixedly connected to a power motor 210 , and the power motor 210 is fixedly arranged on one side of the mounting frame 208 .

[0037] The combination of the power motor 210 and the bidirectional threaded rod 209 enables the height of the mounting base 101 to be precisely controlled by the forward and reverse rotation of the power motor 210, thereby achieving automatic adjustment and greatly improving the convenience and efficiency of operation, especially in test scenarios where frequent height adjustment is required.

[0038] Furthermore, the left and right ends of the bidirectional threaded rod 209 are threadedly connected with threaded sleeves 107 , and the inner wall of the threaded sleeve 107 is slidably connected with a limit rod 211 , which is fixedly arranged on the opposite side of the mounting frame 208 .

[0039] The limit rod 211 is slidably connected to the inner wall of the threaded sleeve 107, and can provide mechanical limit when reaching a predetermined height or limit position, thereby preventing excessive lifting from causing equipment damage or safety accidents, and ensuring the safety of operation.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
