Description

Technical Field

[0001] The utility model relates to the technical field of touch display screens, in particular to a dust-proof touch display screen. Background Art

[0002] A touchscreen display, also known as a touch screen or touch panel, is an inductive liquid crystal display. It utilizes the human body's current or pressure sensing principles to receive input signals from contactors. When a finger or other conductive object touches a graphical button on the screen, the tactile feedback system on the display activates various connected devices according to pre-programmed instructions, thereby enabling host computer operations.

[0003] However, current touch screens still have the following shortcomings when in use: 1. They usually do not have a dust-proof effect. When they are not in use, dust can easily stick to their surface, affecting their appearance. Some touch screens have a dust-proof film directly adhered to their surface. Although this can isolate the display from the external environment and prevent dust from staying on the display, it may reduce the screen's light transmittance, resulting in increased screen reflection and affecting the user's visual experience. At the same time, the thickness and hardness may affect the sensitivity of the touch screen to a certain extent, making it inconvenient to use the touch screen; 2. It is usually inconvenient to install and disassemble the touch screen and the frame of the external device, making maintenance more troublesome.

[0004] Therefore, it is necessary to design a dust-proof touch display screen to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the present invention is to provide a dustproof touch display screen to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A dustproof touch display screen includes a touch display screen body, a display screen frame fixedly connected to the outside of the touch display screen body, notches on the left and right sides of the display screen frame, a lap tube connected to the inside of the notch on the left, and a roller connected to the inside of the notch on the right, a dustproof film provided on the outside of the roller, and multiple connecting components fixedly provided at the four corners of the display screen frame.

[0008] As a preferred solution of the present invention, the top and bottom of the overlapping cylinder on the left are fixedly connected inside the notch, and the top and bottom of the winding cylinder on the right are rotatably connected inside the notch.

[0009] As a preferred solution of the present invention, the top and bottom of the reel are both connected to return springs.

[0010] As a preferred solution of the present invention, a magnetic notch is further provided inside the overlapping tube, and the magnetic notch is made of magnetic material.

[0011] As a preferred solution of the present invention, a pull block is fixedly provided on one side of the overlapping tube on the dustproof film, and a magnetic block is provided on the back of the pull block, and is connected by internal magnetic attraction of the magnetic block and the magnetic notch.

[0012] As a preferred solution of the present invention, the plurality of connection components include vertical frames fixedly mounted on the four corners of the display screen frame, a horizontal frame fixedly connected to an upper position on one side of the vertical frame, and a connection hole is opened on the horizontal frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the present invention, a dust-proof touch screen is provided. When using the touch screen, when dust-proof operation is required, the dust-proof film located at the outer end of the right roller is pulled out and moved to be inserted into the inside of the overlapping tube located on the left for magnetic connection, so that the dust-proof film covers the outer surface of the touch screen, thereby achieving dust-proof operation on the surface of the touch screen. When using the touch screen, the dust-proof film can be removed.

[0015] 2. In the present invention, a dustproof touch screen is provided. When installing the touch screen, it can be abutted against the inner wall of the outer frame of the device through multiple connecting components and fixed with small screws, thereby facilitating the installation and disassembly between the touch screen and the device frame.
