[0017] The present invention will be further described below with reference to specific examples and accompanying drawings.

[0018] like Figure 1-Figure 3 As shown, the utility model describes a universal test bracket, including a workbench 1, a movable plate 2, a calibration support 3 and a driving device, the workbench 1 is provided with a first limiting hole 11, the first limiting hole 11 is provided with a first locking step 12, the movable plate 2 is lifted and installed on the workbench 1 through the calibration support 3, the movable plate 2 is provided with a second limiting hole 21, the second limiting hole 21 is provided with a second locking step 22, the first limiting hole 11 and the second limiting hole 21 always maintain corresponding upper and lower positions.

[0019] The first limiting hole 11 and the second limiting hole 21 in the embodiment of the present invention are square in shape, and the first locking step 12 and the second locking step 22 extend from the four corners of the first limiting hole 11 and the second limiting hole 21 toward the center respectively. When the jig to be tested is located between the first limiting hole 11 and the second limiting hole 21, the upper and lower corners thereof are clamped by the first locking step 12 and the second locking step 22, thereby fixing the jig without affecting the object to be tested that is blocked in the middle of the jig.

[0020] The utility model arranges the movable plate 2 to be able to rise and fall so as to adjust the distance between the first limiting hole 11 and the second limiting hole 21. When in use, the jig is placed in the first limiting hole 11 on the workbench 1, and the jig is supported in the first limiting hole 11 by the first positioning step 12. Then the movable plate 2 is lowered, and the second limiting hole 21 is correspondingly lowered and clamped on the top of the jig, thereby completing the position fixation of the jig and then proceeding to the next step of detection operation. The utility model has a simple structure and can be used with multiple models, avoiding the cost increase caused by making a complete set of test frames specifically for a single model.

[0021] In order to further fix the position of the fixture to prevent it from deviating, magnetic parts are provided on the first positioning step 12 and the second positioning step 22. The magnetic parts produce a magnetic attraction effect on the metal parts of the fixture, thereby enhancing the stability of the fixture after being placed on the workbench 1.

[0022] In the present utility model, sliding parts 23 for movably connecting the calibration support 3 are provided on both sides of the movable plate 2. The calibration support 3 includes a vertical plate 31 and a guide slide 32. The vertical plate 31 is provided with a connecting member 33. The guide slide 32 is fixedly installed between the connecting member 33 and the table surface of the workbench 1. The sliding part 23 is slidably installed on the guide slide 32 through a bearing 231. When the driving device drives the movable plate 2 to rise or fall, the movable plate 2 is restricted in lateral displacement by the guide slide 32, thereby ensuring the precise alignment of the second limiting hole 21 on the movable plate 2 and the first limiting hole 11 on the workbench 1.

[0023] In some embodiments, the number of calibration supports 3 is three groups, and they are respectively installed at different sides of the movable plate 2. When the calibration supports 3 are respectively movably installed on three different sides of the movable plate 2, due to the stability of the triangular relationship, the movable plate 2 can always maintain good stability and balance when moving up and down.

[0024] In some other embodiments, the number of the calibration supports 3 can be four groups, in which the upper ends of the vertical plates 31 in two groups are connected to each other to form a mounting position for mounting the driving device, and in order to avoid the driving device from affecting the detection action due to the shielding of the space above the second limiting hole 21, the two groups of vertical plates 31 are located at the same side edge of the movable plate 2, adjacent to and parallel to each other, specifically, the number of the calibration supports 3 is four groups, in which the vertical plates 31 in two adjacent groups of the calibration supports 3 are mounted on the same side edge of the movable plate 2, and the upper ends are connected to form a mounting portion 34 for mounting the driving device, and the output end of the driving device is connected to the edge of the movable plate 2, so as to avoid the driving device from causing adverse effects due to improper mounting position.

[0025] Since the vertical plate 31 needs to be always kept in an upright state to support the always vertical guide slide rod 32, and the weight of the driving device mounted on one side of the vertical plate 31 is too large to cause the vertical plate 31 to tilt to one side, it is necessary to strengthen and fix the upright position of the vertical plate 31, and in the specific implementation of the embodiment, the side of the vertical plate 31 away from the guide slide rod 32 is provided with a reinforcing member 4 connected to the surface of the vertical plate 31 and the surface of the workbench 1.

[0026] The above embodiments are only the preferred embodiments of the present application, and are only used for explaining the present application, but not limiting the present application, and any change, replacement, combination, simplification, modification and the like made by the person skilled in the art without departing from the spirit and essence of the present application and the principle should be equivalent replacement, and should be included in the protection scope of the present application.
