Description

Technical Field

[0001] The utility model relates to the technical field of infrared touch screens, in particular to an infrared touch screen with a protective structure. Background Art

[0002] Infrared technology touch screens are composed of infrared emitting and receiving sensing elements installed on the touch screen frame. An infrared detection network is formed on the screen surface. Any touching object can change the infrared on the contact point to realize touch screen operation. The existing infrared touch screens do not have a protective structure and are easily affected by friction during storage and transportation, resulting in screen noise, which seriously affects the overall pass rate of infrared touch screens.

[0003] The Chinese patent publication number is CN210109780U. The patent discloses a new type of anti-machine shock infrared touch screen all-in-one machine, whose structure includes a machine body, a groove, a card slot, an infrared touch screen, a support seat, a decorative groove, a connecting line and a protective cleaning device. The protective cleaning device is arranged at the right end of the inner side of the groove, and then a pulling force is applied to the handle groove on the movable rod. The infrared touch screen is repeatedly wiped and cleaned by a sponge brush at the bottom of the movable rod, and the sponge brush can be quickly disassembled and cleaned by sliding the slider and the slide groove. It is easy to use. When the infrared touch screen needs to be repaired, a pulling force is applied to the movable rod, and the movable rod drives the protective cloth to rotate and pull out in the box through a ruler spring, and the buckle in the spring groove is fixed by the spring and the card slot, so that the protective cloth covers and protects the infrared touch screen, and a striking warning reminder is given through a warning word.

[0004] In the above technical solution, by applying a pulling force to the movable rod, the movable rod drives the protective cloth to rotate and pull out in the box through the ruler spring, and the buckle in the spring slot is fixed in place with the slot through the spring, so that the protective cloth covers and protects the infrared touch screen. However, in the above existing technical solution, since the protective cloth is made of flexible material, the impact resistance and scratch resistance of the protective cloth are weak, and it is impossible to prevent the infrared touch screen from being broken due to accidental collision, causing the infrared touch screen to leak or be damaged, affecting the use of the infrared touch screen. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes an infrared touch screen with a protective structure. The protective plate is pulled, and the rack rotates around the gear meshing, and the protective plate at the rear end face of the body is rotated to the front end face of the body until the protective plate completely covers the screen body, thereby protecting the screen body and preventing the glass on the surface of the screen body from being broken after being hit, which affects the use of the screen body.

[0006] The technical solution to achieve the purpose of the utility model is: an infrared touch screen with a protective structure, including a base, a body is fixedly installed on the top wall of the base, a screen body is arranged on the front surface of the body, and also includes;

[0007] A fixed block, wherein the fixed block is fixedly installed on the side wall of the machine body, a rotating rod is rotatably installed on the top wall of the fixed block, the rotating rod penetrates the fixed block and extends to the bottom of the fixed block, gears are fixedly installed on both ends of the side wall of the fixed block, two slide grooves are provided on the front and rear side walls of the machine body, a rack is meshed and installed on the side wall of the gear, a plurality of protective plates are equidistantly installed on the side wall of the rack, two sliders are fixedly installed on the side walls of the protective plates at both ends of the rack, and the sliders are slidably installed on the inner side walls of the slide groove.

[0008] In some embodiments, the rack is made of a flexible material.

[0009] In some embodiments, the two slide grooves are distributed on both sides of the screen body.

[0010] In some embodiments, a through groove is formed on the side wall of the protective plate on which the slider is fixedly mounted at the front end of the machine body, a mounting plate is disposed inside the through groove, and cleaning cotton is disposed on the side wall of the mounting plate.

[0011] In some embodiments, a handle groove is formed on a wall surface of the mounting plate on one side away from the cleaning cotton.

[0012] Compared with the prior art, the utility model has the following significant advantages:

[0013] First: According to the utility model, when the screen body needs to be protected, the protective plate is pulled to move the slider along the direction of the slide groove. At this time, the rack meshes and rotates around the gear, and the protective plate at the rear end face of the body is rotated to the front end face of the body until the protective plate completely covers the screen body, thereby protecting the screen body and preventing the glass on the surface of the screen body from being scratched or broken after collision, causing the screen body to leak or be damaged, affecting the use of the screen body.

[0014] Secondly: the utility model installs the mounting plate on the first protective plate on the front end surface of the screen body, and then holds the handle groove to pull the protective plate to protect or open the screen body. The cleaning cotton on the side wall of the mounting plate can clean the surface of the screen body while moving back and forth to prevent dust from sticking to the surface of the screen body. When the cleaning cotton needs to be replaced later, the mounting plate can be removed from the inside of the through groove by removing the bolts, and then the cleaning cotton can be replaced, thereby improving the practicality of the device.
