The second pressure block 45 applies the driving force generated by the second drive component 43 precisely and stably to both sides of the cabinet under test, enabling various types of strength tests to be performed on the cabinet, including but not limited to static load tests, durability tests, and impact tests. These tests are designed to simulate various load conditions that the cabinet may encounter during actual use, thereby comprehensively evaluating its structural strength and reliability. The drive unit 421 moves along the preset direction of the guide groove 441. As the drive motor 46 runs, it drives the support block 42 to move up or down, measuring the strength of the upper and lower positions of the side wall of the cabinet.

[0042] It is worth mentioning that the base plate 1 and the top plate 2 are provided with second limiting through holes 7 on both sides, and the second slide groove 71 is provided on both sides of the second limiting through hole 7. The upper and lower parts of the second slide groove 71 are provided with several equally spaced second through holes 72. The second slide groove 71 prevents the slider 41 from disengaging. Through the multiple second through holes 72 at different positions, the slider 41 is fixed in different positions to adapt to cabinets of different widths.

[0043] It is worth mentioning that the clamping mechanism 5 includes a movable plate 51, with extensions 511 on both sides of the bottom of the movable plate 51, and anti-detachment parts 512 on both sides of the extensions 511, and is slidably disposed in the first slide groove 11.

The extensions 511 move along the direction of the first limiting through hole 12, the anti-detachment parts 512 prevent the movable plate 51 from disengaging from the first limiting through hole 12 when it moves back and forth, and the fasteners 6 fix the movable plate 51 in the adjusted position.

[0044] It is worth mentioning that telescopic cylinders 52 are provided on both sides of the movable plate 51, and a clamping plate 53 is provided between the piston rods of the two telescopic cylinders 52. The cabinet is clamped and fixed by the clamping plate 53 to prevent displacement during the strength test of the cabinet and to ensure the accuracy of the measurement data.

[0045] It is worth mentioning that the base plate 1 has first limiting through holes 12 on both sides for the extension 511 to pass through, and first sliding grooves 11 are provided on both sides of the first limiting through holes 12. The base plate 1 has several equally spaced threaded holes 13 and is provided on one side of the first limiting through holes 12. Fasteners 6 are threaded to the threaded holes 13. Through multiple threaded holes 13 at different positions, the movable plate 51 is fixed in different positions to adapt to cabinets of different widths.

[0046] It is worth mentioning that the fixing component 8 includes a pin 81, which is inserted into the first through hole 412 and the second through hole 72. The pin 81 has a head 82, and one end of the head 82 is provided with at least one magnet 83, which is magnetically attracted to the substrate 1 or the top plate 2. The head 82 is provided with a pull ring 84. By inserting the pin 81 into the first through hole 412 and the second through hole 72, the slider 41 is fixed in a preset position. The magnetic attraction method prevents the pin 81 from disengaging from the connection with the first through hole 412 and the second through hole 72, ensuring connection stability.

[0047] The working principle of this utility model is described as follows:

[0048] Example 1

[0049] When it is necessary to adjust the position of the movable plate 51, loosen the fastener 6 to disconnect the movable plate 51 from the base plate 1. After moving the movable plate 51 to the preset position, ensure that the fastener 6 coincides with the threaded hole 13, and then tighten the fastener 6 to fix the movable plate 51 to the base plate 1, providing a support point for the telescopic cylinder 52.

[0050] Example 2

[0051] When the position of slider 41 needs to be adjusted, all pins 81 are removed from the first through hole 412 and the second through hole 72 to disconnect slider 41 from substrate 1 and top plate 2. At this time, slider 41 can be moved to adjust the second pressure mechanism 4 to the preset position. After ensuring that the first through hole 412 and the second through hole 72 coincide, the pins 81 are inserted into the first through hole 412 and the second through hole 72 in sequence to ensure that slider 41 is fixed in the moved position and to provide a reliable support point for the second pressure mechanism. In addition, the magnetic attraction position of the head 82 of the pin 81 located on the top plate 2 can be the top of the top plate 2 or the inner top.

[0052] The above design scheme can enable the product to achieve the advantages of good adaptability and reduced input costs.

[0053] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
