The height of the second column can be adjusted by rotating the second column.

[0009] In the aforementioned TV motherboard testing fixture, an elastic element is provided in the groove, and the bottom of the first column contacts the elastic element.

[0010] In the aforementioned TV motherboard testing fixture, the elastic element is a spring.

[0011] In the aforementioned TV motherboard testing fixture, the lower end of the second column is an arc-shaped end.

[0012] In the aforementioned TV motherboard testing fixture, the base is provided with a vertical plate, the drive module is mounted on the vertical plate, the vertical plate is provided with a limiting block, the limiting block is provided with a through hole, and the pressure plate is provided with a guide post on the side facing away from the contour seat, the guide post and the through hole are slidably engaged.

[0013] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0014] In this invention, a contour base is used to position the TV motherboard, and a top post on the pressure plate is used to press the TV motherboard, thereby fixing the TV motherboard in place. This makes it convenient to insert test cables into the TV motherboard. Furthermore, the top post design allows for a gap between the pressure plate and the TV motherboard, making it easier to insert test cables. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0023] Reference Figures 1 to 3 As shown, a TV motherboard testing fixture includes a base 1, a pressure plate 2 and a drive module 3. The base 1 is provided with a contour seat 4 for positioning the TV motherboard. The pressure plate 2 is located at the output end of the drive module 3. The drive module 3 drives the pressure plate 2 to rise and fall. The pressure plate 2 is provided with multiple top posts 5.

[0024] When the pressure plate 2 descends, the top column 5 can press the TV motherboard onto the contour seat 4, so that there is a gap between the pressure plate 2 and the TV motherboard;

[0025] The TV motherboard is positioned using the contour base 4, and then the TV motherboard is pressed down using the top post 5 on the pressure plate 2, thereby fixing the TV motherboard in place. This makes it easier to insert test cables into the TV motherboard. In addition, the setting of the top post 5 leaves a gap between the pressure plate 2 and the TV motherboard, making it easier to insert test cables.

[0026] In this embodiment, the contour base 4 is provided with a contour groove 41 adapted to the TV motherboard. The contour groove 41 can position the TV motherboard and ensure that the TV motherboard will not move randomly. In addition, an elastic layer 42 can be provided in the contour groove 41 to avoid damaging the TV motherboard.

[0027] In this embodiment, the top post 5 includes a first post 51 and a second post 52. The first post 51 is fixed on the pressure plate 2, and the second post 52 is connected to the first post 51. The second post 52 is used to press the TV motherboard. The height of the second post 52 is adjustable. By adjusting the height of the second post 52, it can be ensured that the top post 5 will not press down on the TV motherboard excessively, thus avoiding damage to the TV motherboard. In practice, the second post 52 is adjusted according to the actual size of the TV motherboard.

[0028] Specifically, the lower part of the outer peripheral surface of the first column 51 is provided with an external thread, and the upper part of the second column 52 is provided with a groove 521 for accommodating the first column 51. The inner peripheral wall of the groove 521 is provided with an internal thread, and the external thread is threadedly connected to the internal thread. The height of the second column 52 can be adjusted by rotating the second column 52, which is relatively convenient.

[0029] Furthermore, an elastic element 53 is provided in the groove 521. The bottom of the first column 51 contacts the elastic element 53. After the second column 52 is adjusted to the correct height, the elastic element 53 can be used to tighten the threads of the second column 52 and the first column 51 to prevent the second column 52 from becoming loose.

[0030] Preferably, the elastic element 53 is a spring.

[0031] In some other embodiments, a clamp-locking structure can also be used to connect the first column 51 and the second column 52. Loosening the clamp allows the height of the second column 52 to be adjusted.

[0032] In some other embodiments, the elastic element 53 may be an elastic metal strip.

[0033] In this embodiment, the lower end of the second column 52 is an arc-shaped end. While it can press the TV motherboard tightly, it can reduce the contact area between the top column 5 and the TV motherboard, thus preventing the top column 5 from pressing against the electronic components on the TV motherboard.

[0034] In this embodiment, a vertical plate 11 is provided on the base 1, and a drive module 3 is provided on the vertical plate 11. A limiting block 12 is provided on the vertical plate 11, and a through hole is provided on the limiting block 12. A guide post 13 is provided on the side of the pressure plate 2 facing away from the contour seat 4. The guide post 13 is slidably engaged with the through hole. The engagement of the guide post 13 with the through hole can restrict the movement direction of the pressure plate 2, ensuring that the pressure plate 2 can only move up and down.

[0035] In this embodiment, the drive module 3 is a pneumatic cylinder, an electric cylinder, or a quick clamp.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
