Description

Technical Field

[0001] This utility model belongs to the field of electronic manufacturing technology, and specifically relates to a cleaning auxiliary frame for LCD screens. Background Technology

[0002] An LCD screen uses liquid crystal material as its basic component, filling the space between two parallel plates. By applying voltage, the arrangement of molecules within the liquid crystal material is changed to achieve light blocking and transmission, displaying images of varying depths and staggered shapes. An LCD screen cleaning support frame is a device or tool rack used to assist in cleaning work. It is mainly used to fix and support items to be cleaned, enabling more efficient and safer cleaning. The design and material selection of the cleaning support frame are crucial to its functionality and durability. However, the LCD screen support frames on the market are suitable for a limited number of LCD screens, requiring the preparation of multiple sizes of support frames, which is inefficient. Furthermore, ordinary LCD screen support frames have a single placement angle, making it difficult to see some dust and stains at the same angle, requiring workers to move them for observation, which is time-consuming and laborious. To solve the problems mentioned above, we propose a cleaning support frame for LCD screens. Utility Model Content

[0003] The purpose of this utility model is to provide a cleaning auxiliary frame for LCD screens, which has the advantages of high applicability and multi-angle cleaning.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cleaning auxiliary frame for LCD screens, comprising a frame box, a rotating shaft rotatably connected to the center of the bottom of the frame box, a gear fixedly sleeved on the top surface of the rotating shaft, a rack A meshing on the back surface of the gear, a U-shaped plate sleeved on the back surface of the rack A, a sliding groove A provided at the front end of the inner wall of the U-shaped plate, a rack B meshing on the front surface of the gear, a J-shaped plate sleeved on the front surface of the rack B, a slider A bolted to the right side of the front surface of the J-shaped plate, and the surface of the slider A slidingly connected to the interior of the sliding groove A, a spring bolted to the left end of the inner wall of the J-shaped plate, a connecting plate bolted to the right side of the spring, and the rear end of the right side of the connecting plate bolted to the rear end of the left side of the U-shaped plate, a placement plate bolted to the top of the connecting plate, a right clamping plate bolted to the right side of the top of the U-shaped plate, a left clamping plate bolted to the left side of the top of the J-shaped plate, and an angle adjustment mechanism provided at the bottom of the frame box.

[0005] The above technical solution involves the following steps: the right clamping plate moves to the right, causing the U-shaped plate to move; the U-shaped plate moves rack A; rack A moves, causing the gear to rotate; the gear rotates, causing rack B to move to the left; rack B moves the J-shaped plate; the J-shaped plate moves the left clamping plate to the left; slider A and slide A limit the movement of the J-shaped plate; the U-shaped plate moves, causing the connecting plate to move; the connecting plate stretches the spring; after the LCD screen is fully placed on the placement plate, the spring rebounds, causing the U-shaped plate and J-shaped plate to retract inward; the right and left clamping plates move inward to clamp and fix the LCD screen. This multi-specification clamping cleaning auxiliary frame can adapt to LCD screens of different sizes and shapes, eliminating the need for frequent changes of clamps or cleaning tools, thus saving time and labor costs.
