Abstract

The invention relates to a frame component for an infrared touch screen and the infrared touch screen, wherein the frame component for the infrared touch screen comprises a front frame, a touch frame and a glass panel, the touch frame is arranged in the frame body of the front frame, the peripheral edge of the glass panel is embedded and limited in the front frame, the frame body is provided with a drainage groove, the drainage groove comprises a first drainage groove and a second drainage groove, one end of the second drainage groove is communicated with the first drainage groove, and the other end of the second drainage groove is communicated with the outside of the infrared touch screen. Through the framework sets up water drainage tank, the drop of glass panel outside surface is condensed and is formed rivers and from glass panel with when the gap between the preceding frame is oozed, can follow first water drainage tank flows, and further follows the second water drainage tank flows outside the equipment, effectively prevents that the water droplet from crossing the frame subassembly gets into inside the infrared touch screen complete machine structure, and then leads to rustting or cause the influence to other subassembly's normal function.

Description

Frame component for infrared touch screen and infrared touch screen Technical Field The invention relates to the technical field of infrared touch display equipment, in particular to a frame component for an infrared touch screen and the infrared touch screen. Background At present, the infrared touch display device with the touch control function is widely applied to the fields of education, commercial advertisement, video entertainment, medical treatment, travel, artificial intelligence simulation and the like. In the prior art, infrared touch display devices are formed from separate infrared touch screen products and separate display products that are subsequently assembled together. The conventional infrared touch screen comprises a frame assembly 1 and a backlight module (not shown), wherein the frame assembly 1 comprises a front frame 10, a touch frame 20 and a glass panel 30, the front frame 10 is of a frame-shaped structure formed by splicing a plurality of frames, the glass panel 30 is limited in the frames, a containing groove 50 is formed in the frames, the touch frame 20 is arranged in the containing groove 50 of the frames, please refer to fig. 1-3, fig. 1 is a front view of the infrared touch screen structure in the prior art, fig. 2 is a schematic view of a local structure angle of the infrared touch screen in the prior art, fig. 3 is a schematic view of a local structure angle of the infrared touch screen in the prior art, and due to gaps between the glass panel 30 and the front frame 10, water drops formed by condensation of water vapor on the glass panel in the process of accidental sputtering or in the humid weather in the south are converged, as shown in fig. 4, and are easily permeated into the frame assembly from the connecting gaps as shown by arrows in fig. 1-3, further influence on the assembly of the touch frame 20 and the backlight module, even the touch module is caused, and the problem of rust is caused by failure of functions and the like. Disclosure of Invention Based on the above, an object of the embodiments of the present invention is to provide a frame assembly for an infrared touch screen, which has the advantages of simple structure, low cost and capability of effectively preventing water from entering the device from rusting. The embodiment of the invention achieves the aim through the following technical scheme: The frame component for the infrared touch screen comprises a front frame, a touch frame and a glass panel, wherein the front frame is of a frame-shaped structure and comprises a plurality of frame bodies and a plurality of corner connecting pieces, two adjacent frame body ends are detachably spliced through the corner connecting pieces, the touch frame is arranged in the frame body, the periphery edge of the glass panel is embedded and limited in the front frame, the frame body comprises a first surface and a second surface, the first surface extends along the length direction of the frame body and is perpendicular to the glass panel and is abutted with the edge of the glass panel, the second surface is parallel to the glass panel and is positioned on the inner side of the glass panel, the frame body is provided with a drainage groove, the drainage groove comprises a first drainage groove and a second drainage groove, the first drainage groove is positioned on the first surface, extends along the length direction of the frame body and corresponds to the edge position of the glass panel, and the second drainage groove is positioned on the second surface, one end of the second drainage groove is communicated with the infrared touch screen, and the infrared drainage screen is communicated with the other end of the infrared touch screen; the frame body is provided with a containing groove along the length direction of the frame body, the touch frame is arranged in the containing groove, the touch frame comprises a plurality of infrared filter strips, and the infrared filter strips are arranged at the opening of the containing groove.
