Description

Universal fixture for drop test

technical field

The utility model relates to the technical field of display screen testing, in particular to a universal fixture for a drop test.

Background technique

The mobile phone display drop test refers to fixing the mobile phone display on a fixture, then dropping balls onto the display at different heights, and then checking whether the display is damaged. Because the size of the display screen of the mobile phone in the prior art has many kinds, so just need the jig of various sizes to cooperate, the adaptability like this is low, and it is troublesome to use.

Contents of the invention

The technical problem to be solved by the utility model is to provide a universal fixture for drop experiments with high adaptability and convenient use.

The technical solution adopted by the utility model is: a universal fixture for drop test, which includes four L-shaped connecting parts and four connecting parts, and the four L-shaped fixing parts are respectively the first fixing part and the second fixing part , the third fixing piece and the fourth fixing piece, and the adjacent parts of the first fixing piece, the second fixing piece, the third fixing piece and the fourth fixing piece are all provided with telescopically adjustable connecting pieces.

Using the above structure compared with the prior art, the utility model has the following advantages: in this way, the distance between each fixing piece can be adjusted, and then the size of the entire jig can be adjusted, so that it can adapt to display screens of different sizes, and the adaptability is relatively high. High and easy to use.

Preferably, it also includes a supporting piece for supporting the display screen placed between the four L-shaped fixing pieces, and the supporting piece is provided with accommodating grooves for accommodating the four L-shaped fixing pieces and the display screen. In this way, when it is necessary to test a solid drop, the support can be installed on it, and when it is necessary to test a hollow drop, the support is removed, which has a high adaptability and is more convenient to use.

Preferably, the connecting piece is provided with a plurality of protruding points, and the L-shaped fixing member is provided with recesses matching with the protruding points. In this way, each bump corresponds to a size, which is more convenient for users to adjust.

Detailed ways

The utility model is further described below in conjunction with the accompanying drawings and specific embodiments, but the utility model is not limited to the following specific embodiments.

A universal fixture for a drop test, which includes four L-shaped connecting pieces and four connecting pieces 1, the four L-shaped fixing pieces are respectively a first fixing piece 2, a second fixing piece 3, a third fixing piece 4 and The fourth fixing part 5 , and adjacent parts of the first fixing part 2 , the second fixing part 3 , the third fixing part 4 and the fourth fixing part 5 are provided with telescopically adjustable connecting parts 1 . Wherein the connecting piece 1 is provided between the first fixing piece 2, the second fixing piece 3 and the fourth fixing piece 5, and the connecting piece is arranged between the second fixing piece 3, the first fixing piece 2 and the third fixing piece 4 1. There is a connecting piece 1 between the third fixing piece 4, the second fixing piece 3 and the fourth fixing piece 5, and there is a connecting piece between the fourth fixing piece 5, the third fixing piece 4 and the first fixing piece 2 1. There is a sliding connection between the connecting piece and the fixing piece, and a locking mechanism is provided to lock the connecting piece 1 and the fixing piece.

It also includes a supporting member 6 for supporting the display screen placed between the four L-shaped fixing members, and the supporting member 6 is provided with an accommodating groove 7 for accommodating the four L-shaped fixing members and the display screen. When it is necessary to use the support, place the whole of the four fixing parts into the accommodation groove of the support, then place the display screen between the four fixing parts, adjust the size, and then start the experiment.

The connector 1 is provided with a plurality of protruding points, and the L-shaped fixing part is provided with depressions matching the protruding points.
