Background

The liquid crystal display is a flat thin display device, which consists of a certain number of color or black and white pixels, and is placed in front of a light source or a reflecting surface. The liquid crystal display screen has low power consumption, is popular with consumers, and is suitable for electronic equipment using batteries. In the production process of the liquid crystal display, the liquid crystal display is required to be detected for a plurality of times by using a testing machine, wherein the brightness of the liquid crystal display and whether the liquid crystal display has stains or not are detected, the ageing, the heat dissipation performance and the like of the liquid crystal display are required to be fixed and clamped in each detection link, each detection item is different, different clamps are required to be fixedly installed, the size of each display is also different, and the clamps with different sizes are required to be replaced, so that the liquid crystal display is quite troublesome.

Disclosure of Invention

Aiming at the defects in the technology, the utility model provides a fixing clamp for a liquid crystal display screen.

In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a liquid crystal display mounting fixture, includes the fixing base, fixedly on the fixing base be provided with fixture, fixture with the central line of fixing base is the symmetric distribution, fixture includes electronic jar, push-and-pull rod and grip block.

As a further illustration, the push-pull rod is connected to the electric cylinder.

As a further illustration, an integrated molding structure is formed between the push-pull rod and the clamping plate.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and fig. 2, a fixing clamp for a liquid crystal display screen comprises a fixing seat 1, wherein a clamping mechanism 2 is fixedly arranged on the fixing seat 1, the clamping mechanism 2 is symmetrically distributed along the central line of the fixing seat 1, and the clamping mechanism 2 comprises an electric cylinder 5, a push-pull rod 6 and a clamping plate 7.

In this embodiment, the push-pull rod 6 is connected with the electric cylinder 5, and the electric cylinder 5 pushes the push-pull rod 6 to move, so that the clamping plate 7 can clamp the liquid crystal display screen stably, and compared with the traditional clamp, the clamp can clamp the liquid crystal display screen with different sizes.

In this embodiment, an integrally formed structure is formed between the push-pull rod 6 and the clamping plate 7.

In this embodiment, the middle of the clamping plate 7 is provided with the concave groove 8, and when in use, the side surface of the liquid crystal display screen extends into the concave groove 8 and is mutually attached to the inner wall of the clamping plate 7, and the height of the concave groove 8 is 5cm, so that the liquid crystal display screen with different sizes below 5cm thickness can be clamped.

In this embodiment, the side of fixing base 1 still fixedly is provided with mounting panel 3 in addition, be provided with a plurality of screws 4 on the mounting panel 3, through setting up mounting panel 3 and screw 4, can install the anchor clamps on the test machine to controlling means on the test machine still is connected with electronic jar 5 through the wire in addition, during the use, can realize opening and closing electronic jar 5 through controlling means on the test machine.

Working principle: during the use, fix anchor clamps to the test machine through mounting panel 3 and screw 4, place the LCD that will fix in the sunken inslot 8 in centre of grip block 7, and through opening the controlling means on the test machine, start electronic jar 5 through controlling means, drive push-and-pull rod 6 and grip block 7 motion through electronic jar 5, make grip block 7 draw close towards the centre, until grip block 7 and LCD's frame contact and with LCD centre gripping stability, can realize the LCD centre gripping to not unidimensional LCD is fixed, do not need frequent change anchor clamps, the practicality is stronger, use very simple.
