Description

Technical Field

[0001] This invention relates to the field of touch displays, and more particularly to a liquid crystal touch display screen with multiple layers of protection. Background Technology

[0002] LCD touch screen devices typically consist of a screen, fan, main control board, temperature controller, voltage regulator, power controller, etc. Some manufacturers may add printing devices, document reading devices, keyboard devices, paper / card input / output devices, etc., depending on the actual needs of the product environment, such as the supercomputer cabinets used in banks.

[0003] As a typical integrated solution for the entire device, conventional LCD touch screens often overlook the fact that their internal layout is rather chaotic, with messy wiring that hinders maintenance. Additionally, the numerous internal electronic components result in high internal temperatures during operation, posing potential safety hazards.

[0004] Therefore, it is necessary to provide a multi-protected liquid crystal touch screen to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a multi-protected liquid crystal touch screen, which solves the problems of the chaotic internal layout and messy wiring of liquid crystal touch screens, which are often overlooked in integrated whole machines. The messy wiring distribution affects maintenance, and the large number of internal electronic components leads to high internal temperatures during operation, posing potential safety hazards.

[0006] To solve the above-mentioned technical problems, the present invention provides a multi-protection liquid crystal touch screen, comprising: a protective box;

[0007] The mounting slot is located in the middle of the front of the protective box. A display is provided on the rear side of the inner cavity of the mounting slot. Heat sinks are fixedly installed on all four sides of the inner cavity of the mounting slot.

[0008] A heat dissipation device is provided on one side of the inner cavity of the mounting slot. A filter screen is provided in the middle of one side of the protective box. Storage devices are provided on both sides of the inner cavity wall of the mounting slot. An adjustment device is provided inside the storage device. A limiting device is fitted on the outer surface of the adjustment device.

[0009] Preferably, the storage device includes a mounting plate, a storage block is fixedly installed in the middle of one side of the mounting plate, a storage hole is opened on the side of the storage block, a limit groove is opened on both sides of the storage hole, and a threaded hole is opened on one side of the storage hole.

[0010] Preferably, the adjusting device includes a threaded rod, one end of which is fixedly mounted with a limit block, and the other end of which is fixedly mounted with an adjusting block.

[0011] Preferably, the limiting device includes a limiting block, with sliders fixedly installed on both sides of the limiting block, a setting hole in the middle of one side of the limiting block, and a limiting cavity connected to the other side of the setting hole.

[0012] Preferably, a temperature controller, an integrated main control module, a main control board, a switching power supply monitor, a switch protector, and a power controller are fixedly installed on the back of the display.

[0013] Users can control the heat dissipation device to cool the display and internal electronic components using devices such as thermostats.

[0014] When installing the circuit, the user passes the wire through the storage hole and rotates the adjusting block to drive the threaded rod to rotate. The rotation of the threaded rod engages with the threaded hole and moves the limiting device along the limiting groove. The limiting block restricts the wire inside the storage hole.

[0015] Preferably, an installation device is fixedly installed on the side of the protective box. The installation device includes a connecting plate. A connecting cavity is formed in the middle of one side of the connecting plate. Sliding grooves are formed on both sides of the inner cavity of the connecting cavity. A placement groove is provided at the bottom of the connecting cavity. An elastic device is provided inside the sliding groove. A cleaning device is sleeved on the outer surface of the elastic device. A collection device is provided inside the placement groove.

[0016] Preferably, the collecting device includes a collecting block, and a collecting groove is formed in the middle of the top of the collecting block.

[0017] Preferably, the cleaning device includes a movable block, with squeezing blocks fixedly installed on both sides of the movable block, a wiping cotton provided at the bottom of the movable block, and a pull rod fixedly installed in the middle of one side of the movable block.

[0018] Preferably, the elastic device includes a slide bar, and a spring is sleeved on the outer surface of the slide bar.

[0019] Preferably, a magnet is provided at the top of the placement slot.

[0020] The user holds the lever and moves the cleaning device downwards. The moving block drives the squeezing block to slide down the slide bar, causing the wiping cotton to move downwards and push the dust on the surface of the filter screen downwards, so that the dust falls into the inside of the collection tank.

[0021] Users can forcefully remove the collection block from the surface of the magnet for cleaning and then put it back for future use.

[0022] Compared with related technologies, the multi-protection liquid crystal touch screen provided by the present invention has the following beneficial effects:

[0023] This invention provides a multi-protected liquid crystal touch screen. By designing it as a modular integrated product, it reduces the overall internal space required, making the product relatively thin and enhancing the outdoor protection of both the product and the screen itself. Simultaneously, the internal temperature control component monitors the temperature of the internal electrical components, the heat dissipation device cools the internal components, and a storage device collects the wiring, preventing it from becoming cluttered. This device has a simple structure, is highly practical, and provides multiple layers of protection to ensure the safe use of the electronic components inside the display screen, reducing potential safety hazards.

[0024] This invention provides a multi-protected liquid crystal touch screen. By holding the lever and sliding it along the slide bar, the wiping cotton pushes away the dust adhering to the surface of the filter screen. When not in use, the spring's restoring force pushes the cleaning device back to its original position. This device has a simple structure, is highly practical, and can quickly remove the dust adhering to the surface of the filter screen, keeping the filter screen surface clean and maintaining ventilation.
