This embodiment provides a TV screen test fixture, which is used to clamp and fix the TV screen 1 . The test fixture includes a frame 2 , a supporting structure 3 , a pressure block 4 , a beam 5 , screws 6 and bolts 7 .

The frame 2 is surrounded by four elongated frames 21, and the frame 2 has a front and a back corresponding to the front. When the TV is installed on the test fixture, the frame 2 is sleeved on the TV screen 1 . It should be noted that the size of the frame 2 is adapted to the size of the TV screen 1 .

The supporting structure 3 is used to support the TV screen 1 , and the supporting structure 3 is a bottom plate abutting against the TV screen 1 . The bottom plate is arranged on the front of the frame 2, and the bottom plate is fixedly connected with the four frames 21 of the frame 2 through screws, so that the frame 2 and the bottom plate accommodate and support the TV screen 1 together. Further, the bottom plate is set in a hollow structure, thereby reducing the weight of the bottom plate itself. It should be noted that the support structure 3 can also be set as other structures (such as a flange structure set on the front of the frame 2 ), as long as the support structure 3 can support the TV screen 1 . In addition, the fixed connection method between the support structure 3 and the frame 2 can also be set as a welding fixing method or a bolt connection method, as long as the support structure 3 and the frame 2 can be fixedly connected.

The pressing block 4 includes a pressing seat 41 and two parallel pins 42 , wherein one end of the two pins 42 is integrally connected with the pressing seat 41 . The pin 42 is provided with two first fixing slots 421 adapted to the bolt 7 and arranged parallel to each other. The first fixing slots 421 extend from one end of the pin 42 connected to the pressure seat 41 to the other end of the pin 42 . It should be noted that one or more pins 42 on the pressing block 4 can also be set, which can be set according to actual conditions. In addition, one or more first fixing slots 421 on the pin 42 may also be provided. In order to enhance the fixing strength of the pressing block 4 , each pin 42 on the pressing block 4 may also be provided with a plurality of first fixing grooves 421 arranged in parallel.

The back of the frame 2 is provided with two rectangular parallelepiped crossbeams 5, and the two crossbeams 5 are preferably arranged parallel to each other. Both ends of the crossbeam 5 are fixedly connected to two opposite frames 21 of the frame 2 by screws 6 , so that the crossbeam 5 is fixed on the back of the frame 2 . The beam 5 includes two end surfaces and first, second, third and fourth side surfaces connected to the two end surfaces. Wherein, the first side is opposite to the second side, and the third side is opposite to the fourth side. The beam 5 also includes two guide slots 51 arranged in parallel and adapted to the pins 42 of the pressure block 4 , and a second fixing slot 52 adapted to the bolt 7 .

It should be noted that the beam 5 can be set in other regular shapes, such as prisms and the like. The beam 5 can also be fixedly connected to the frame 2 by means of bolt connection. The number of guide grooves 51 on the beam 5 is equal to the number of pins 42 of the pressure block 4 , and when the number of pins 42 of the pressure block 4 is set to one, the number of guide grooves 51 on the beam 5 is also set to one. When the pins 42 of the pressing block 4 are set to N (N is greater than or equal to 2), there are also N guide grooves 51 on the beam 5, and the gap between the two guide grooves 51 on the beam 5 is the same as the two pins 42 on the pressing block 4. The gap between them is equal.

Assembly: first place the TV screen 1 in the jig so that the front of the TV screen 1 is in contact with the bottom plate, and the frame 2 is set on the shell of the TV screen 1 . Wherein, the size of the frame 2 is adapted to the frame 21 of the TV screen 1 . Then a pressing block 4 is installed on each beam 5 . Specifically, first insert the two pins 42 of the pressing block 4 into the two guide grooves 51 of the crossbeam 5 respectively, and then pass the bolt 7 through the second fixing groove 52 of the crossbeam 5 and the first fixing groove 421 on the pins 42 of the pressing block 4, And tighten the bolt 7 with a nut, so that the briquetting block 4 and the beam 5 are tightly connected. After the pressure block 4 is installed on the beam 5 , the beam 5 connected with the pressure block 4 is further installed on the back of the frame 2 . During installation, place the pressure seat 41 of the pressure block 4 on the TV screen 1 side, and then use the screws 6 to fix the two ends of the crossbeam 5 on the two opposite frames 21 of the frame 2, which completes the installation of the test fixture.

Adjustment: According to the specific structure of the TV screen 1, the position of the pressing block 4 and the distance between the pressing block 4 and the bottom plate can be adjusted arbitrarily. When the pressing block 4 is just aligned with the structure (such as bolts, bumps, etc.) in the TV screen 1 that prevents it from pressing the TV screen 1, loosen the bolt 7 connecting the pressing block 4 and the beam 5, and make the pressing block 4. Move to a suitable position along the length direction of the beam 5. After the pressure block 4 moves to a suitable position, adjust the depth of the pin 42 of the pressure block 4 inserted into the guide groove 51 on the beam 5, so that the pressure block 4 is close to or away from the bottom plate, so that the pressure seat 41 of the pressure block 4 can better abut against TV screen 1. Tighten the bolt 7 again, so that the pressing block 4 is firmly fixed on the beam 5, and the pressing block 4 and the bottom plate are clamped to fix the TV screen 1 . It should be noted that one or more beams 5 may also be arranged on the back of the frame 2 . In order to strengthen the fixing strength of the test fixture to the TV screen 1 , more than two pressing blocks 4 can be arranged on each beam 5 .

In the utility model, at least one crossbeam 5 is arranged on the back of the frame 2 with the support structure 3 on the front, and a pressure block 4 is arranged on the crossbeam 5 . Wherein, the pressing block 4 can move along the length direction of the beam 5 , and the pressing block 4 can also be adjusted away from or close to the supporting structure 3 . When using the test fixture to clamp the TV screen 1 , the position of the pressing block 4 is adjusted along the guide groove 51 of the beam 5 so that the pressing block 4 moves to a proper position. Further adjust the pressing block 4 to be close to or away from the supporting structure 3, and fix the pressing block 4 on the beam 5, so that the pressing block 4 and the supporting structure 3 can clamp and fix the TV screen 1 better. The utility model overcomes the technical difficulty in the prior art that a test fixture can only clamp a TV screen 1 with one structure, and realizes that a test fixture can test a variety of TV screens 1 with different structures. Purpose, thereby improving the compatibility of the test fixture, saving resources, and reducing production costs.

Further, based on the above embodiment, in this embodiment, the test fixture further includes a gasket 8 placed between the beam 5 and the bolt 7 .

In this embodiment, in order to prevent the nuts installed in the bolts 7 of the pressing block 4 on the beam 5 from being inserted into the second fixing groove 52 due to wear and other reasons, the connection between the pressing block 4 and the beam 5 will fail. In this embodiment, a gasket 8 is provided between the beam 5 and the bolt 7 . The washer 8 prevents the nut from being inserted into the second fixing groove 52 , thereby avoiding failure of the connection between the pressure block 4 and the beam 5 , thus effectively enhancing the fixing strength between the pressure block 4 and the beam 5 . It should be noted that the gasket 8 is provided with through holes adapted to the bolts 7 , and the number of the through holes is equal to the number of the first fixing slots 421 .
