Description

Technical Field

[0001] This utility model relates to the field of display module connection technology, specifically to a front and rear assembly / disassembly connection device for an LCD display module. Background Technology

[0002] An LCD is constructed by placing a liquid crystal cell between two parallel glass substrates. A TFT (thin-film transistor) is placed on the lower glass substrate, and a color filter is placed on the upper glass substrate. The rotation direction of the liquid crystal molecules is controlled by changing the signals and voltages on the TFTs, thereby controlling whether polarized light is emitted from each pixel to achieve the display purpose.

[0003] According to the search (application number: 201920597497.8), a front and rear assembly and disassembly connection device for an LCD display module is disclosed, comprising a first curved plate, a bracket fixedly connected to the bottom of the first curved plate, a first rubber pad fixedly connected to the inner wall of the first curved plate, a vertical plate fixedly connected to the bottom right side of the first curved plate, a short rod rotatably connected to the top of the mounting assembly via a second bearing, a semi-circular ring fixedly connected to the top of the short rod, and a rubber strip fixedly connected to the inner wall of the semi-circular ring.

[0004] In the process of realizing this utility model, the inventors discovered the following unresolved problems in the prior art: the device uses adjustable components to connect two sets of curved plates in an adjustable manner. Although it can clamp and fix the LCD display module, the connection between the two sets of curved plates relies only on the sliding mechanism and the screw mechanism. During use, when one end of the curved plate is under pressure, it is prone to deformation due to insufficient rigidity, which can damage the module. Improvement is urgently needed. Therefore, we propose a front and rear assembly and disassembly connection device for LCD display modules. Utility Model Content

[0005] The purpose of this utility model is to provide a front and rear assembly and disassembly connection device for an LCD display module, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front and rear assembly and disassembly connection device for an LCD display module, including a curved plate a, a curved plate b placed on one side of the curved plate a, and a crank arm placed on one side of the curved plate b;

[0007] A guide groove is provided in the inner bottom wall of the curved plate a, and a screw is placed in the guide groove. The screw is rotatably connected to the curved plate a through a bearing, and a rotating block is fixedly installed at one end of the screw.

It can be used in conjunction with components such as guide groove, protrusion and reinforcing rod. During the use of the assembly and disassembly connection device, whenever the curved plate a clamps and fixes the module, the protrusion extends into the guide groove. At the same time, since the reinforcing rod and the sleeve are movably connected, the reinforcing rod moves with the protrusion and passes through the inside of the sleeve. During use, whenever one side of the curved plate a is subjected to force, the rigidity of the curved plate a can be increased compared with the existing method because the protrusion is locked in the guide groove and the cooperation between the reinforcing rod and the sleeve can prevent excessive deformation caused by compression and damage to the module.

A rubber ring is fixedly sleeved on the inner side of the end cap, and a groove is provided on the outer side of the end cap. A pinch block is fixedly installed in the groove. It can be used in conjunction with the hidden groove and the end cap. After each adjustment, the end cap can be moved by the pinch block and placed in the groove, and then pressed inward. The rubber ring can limit the inner end of the end cap. The hidden screw design can prevent secondary problems caused by accidental movement by others, and the safety factor is more ideal.

[0013] As an optional solution to the technical solution of this application, the crank arm is provided with a number of uniformly arrayed positioning holes, and a cable tie is fixedly installed on the top of the crank arm. The positioning screw can be moved through the positioning holes of the crank arm and screwed into the pre-set threaded structure on the support for fixing the device. At the same time, the cable tie can limit and regulate the cable.

[0014] As an optional solution to the technical solution of this application, a bolt is movably passed through one side of the slide rail, and a number of uniformly arrayed threaded grooves are opened on one side of the slider. The bolt is screwed into the threaded groove on the same side through the thread. The slider after adjustment can be limited by the screwing of the bolt into the threaded groove to prevent self-slippage.

[0015] As an optional solution to the technical solution of this application, rubber pads are fixedly installed on the inner sides of both curved plate a and curved plate b. The rubber pads are L-shaped and can contact the display module through the rubber pads, avoiding wear caused by hard contact, which meets the usage requirements.
