If the specific posture changes, the directional indications will also change accordingly.

[0035] See also Figures 1 to 4 .

[0036] The utility model comprises a display screen assembly fixing fixture, comprising:

[0037] A clamp body 1 is provided with a plurality of guide rail grooves 11;

[0038] There are multiple side clamps 2, each of which can be slidably installed in any one of the guide rail grooves 11 and can be fastened at any position of the corresponding guide rail groove 11;

[0039] In the clamping state, the display screen assembly 3 is placed on the clamp body 1 , and the multiple side clamps 2 are respectively in contact with different sides of the display screen assembly 3 .

[0040] The present invention does not fix the display screen assembly 3 by pressing it from above, but fixes it by using multiple side clamps to press the display screen assembly 3 from the side, so as to avoid crushing the display area of ​​the display screen. In addition, multiple side clamps can be fastened at different positions of different guide rail grooves 11, so that they can adapt to display screen assemblies 3 of different sizes and specifications, greatly improving the versatility of the clamp. The present invention can flexibly adjust the number and installation position of the side clamps according to the size and number of the display screens, so as to adapt to the needs of fixing the display screen assembly 3 samples in different scenarios.

[0041] In one embodiment, the side clamp 2 includes:

[0042] The fixing rod 21 is slidably engaged with the guide rail groove 11;

[0043] A locking member 22, threadedly connected to the fixing rod 21;

[0044] A driving positioning block 23 is sleeved on the fixing rod 21 and has a degree of freedom of movement along the axial direction of the fixing rod 21;

[0045] A movable positioning block 24 is sleeved on the fixing rod 21 and has a radial degree of freedom of movement along the fixing rod 21;

[0046] The driving positioning block 23 and the movable positioning block 24 are located between the locking member 22 and the clamp body 1 . When the locking member 22 moves toward the clamp body 1 , the driving positioning block 23 presses the movable positioning block 24 to move radially along the fixing rod 21 .

[0047] The side clamp's structural design converts the axial movement of the driven positioning block 23 along the fixed rod 21 into radial movement of the movable positioning block 24 along the fixed rod 21. This allows the movable positioning block 24 to be controlled to move closer to and further from the display assembly 3, thereby clamping and securing the display assembly 3 from the side. Specifically, the fixed rod 21 can be a screw, and the locking member 22 can be a nut that matches the fixed rod 21. During operation, simply rotating the locking member 22 is quick and convenient, and once tightened, it is unlikely to loosen during testing.

[0048] In one embodiment, the driving positioning block 23 and the movable positioning block 24 are in surface contact and the contact surface is an inclined surface. This design makes the driving positioning block 23 and the movable positioning block 24 cooperate more smoothly and is more conducive to the conversion of the movement direction of the two.

[0049] In one embodiment, the driving positioning block 23 and the movable positioning block 24 are both triangular in structure. This design is structurally sound. Specifically, the driving positioning block 23 and the movable positioning block 24 can be designed as a right-angled triangle structure, with the vertical right-angled side of the movable positioning block 24 being used to abut against the side of the display screen assembly 3.

[0050] In one embodiment, a side of the movable positioning block 24 that is used to abut against the display screen assembly is provided with a protective pad 242. The protective pad 242 is used to protect the display screen assembly 3 and can be made of a flexible material, such as rubber.

[0051] In one embodiment, the driving positioning block 23 is provided with a circular hole 231, and the movable positioning block 24 is provided with a waist hole 241. This design is structurally sound, as the circular hole 231 cooperates with the fixing rod 21 to provide axial freedom of movement, while the waist hole 241 cooperates with the fixing rod 21 to provide both axial and radial freedom of movement.

[0052] In one embodiment, the cross-section of the guide rail groove 11 is in an inverted T-shape, and a square slider 211 is provided at the lower end of the fixed rod 21. The square slider 211 and the fixed rod 21 are also in an inverted T-shape as a whole and cooperate with the guide rail groove 11. This design makes the sliding fit between the guide rail groove 11 and the fixed rod 21 more precise. Moreover, when the locking member is locked, it not only fixes the driving positioning block 23 and the movable positioning block 24, but also tightens the fixed rod 21 within the guide rail groove 11, making it less likely that the fixed rod 21 will rotate during locking, resulting in the fixed rod being unable to be locked.

[0053] In one embodiment, the guide rail groove 11 runs from the front of the clamp body 1 to the back of the clamp body 1. With this design, the fixing rod 21 can be directly inserted into the guide rail groove 11 from the back of the clamp body 1, which is convenient for installation and removal and has better practicality.

[0054] In a specific implementation, the clamp body 1 is designed to be plate-shaped, and the plurality of guide rail grooves 11 are arranged parallel to each other.

[0055] In one embodiment, the fixture body 1 is provided with a plurality of mounting holes 12. The mounting holes 12 are used to fit bolts to mount the fixture body 1 on a platform of a vibration or impact test device.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
