The utility model content
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of infrared touch panel framework, and its frame is fixing circuit board better.
For achieving the above object, the utility model adopts following technical scheme:
A kind of infrared touch panel framework, it comprises frame, four circuit boards and four spacing cylinders; Each circuit board is provided with some infrared tubes, some infrared tubes on each circuit board are arranged along the length direction of circuit board, frame becomes a square box by four optical filtering circumferences of cannon bone, each circuit board is installed in the corresponding optical filtering pipe, each optical filtering pipe is served as reasons and only can be seen through the printing opacity tubular body that ultrared material is made into integration, each optical filtering pipe on the roof of circuit board, offer a limiting through hole, offer a limiting through hole on each circuit board, and the limiting through hole of the limiting through hole on the circuit board on the optical filtering pipe, each spacing cylinder can be passed the limiting through hole of filter pipe and circuit board with plugging.
This spacing cylinder is a latch.
Be provided with the groove that power circuit board one end inserts in the sidewall of each optical filtering pipe away from infrared tube, each pipe that filters is provided with a spacing preiection near in the sidewall of infrared tube, and this spacing preiection is kept out in the circuit board one side of infrared tube dorsad.
Be provided with a defining flange in the diapire of each optical filtering pipe, infrared tube is between this defining flange and sidewall.
Each pipe printing opacity tubular body that filters for being made into integration by the PC material.
The beneficial effects of the utility model are as follows:
Above-mentioned utility model is not only carried out spacing in the short transverse of optical filtering pipe to circuit board, also length direction and the Width at the optical filtering pipe carries out spacing to circuit board, make circuit board can firmly be installed in the optical filtering pipe, even the infrared touch panel framework is given a shock, circuit board can not be moved in either direction yet.In addition, because this spacing cylinder can pass the limiting through hole of filter pipe and circuit board with plugging, so, the optical filtering pipe can be integrated tubular body, during assembling, circuit board is inserted in the cavity of optical filtering pipe, again spacing cylinder is inserted the limiting through hole of filter pipe and circuit board, simple for assembly process, and the one-body molded slit of reducing of pipe of filtering, thereby water resistance improved.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
See also Fig. 1 to 5, the utility model relates to a kind of infrared touch panel framework, its better embodiment comprises four circuit boards 30, frame and four spacing cylinders 20, and each circuit board 30 is provided with some infrared tubes 25, and the some infrared tubes on each circuit board 30 are arranged along the length direction of circuit board 30.Frame surrounds a square box by four optical filtering pipes 10, and each circuit board 30 is installed in the corresponding optical filtering pipe 10.Each pipe 10 that filters is served as reasons and only can be seen through ultrared PC(polycarbonate, the printing opacity tubular body that polycarbonate) is made into integration.
Each pipe 10 that filters on the roof 12 of circuit board 30, offer a limiting through hole 125, offer a limiting through hole 35 on each circuit board 30, and limiting through hole 35 is over against this limiting through hole 125, each spacing cylinder 20 can pass a limiting through hole 125 and a limiting through hole 35 with plugging, so, can carry out spacing to circuit board 30 at the length direction of the pipe 10 that filters, when avoiding the infrared touch panel framework to be given a shock, circuit board 30 moves along the length direction of the pipe 10 that filters, thereby makes that the properties of product of infrared touch panel framework are more stable.
In the present embodiment, this spacing cylinder 20 is a latch.
Be provided with the groove 160 that power circuit board 30 1 ends insert in the sidewall of each pipe 10 of filtering away from infrared tube 25, each pipe 10 that filters is provided with a spacing preiection 165 near in the sidewall of infrared tube 25, this spacing preiection 165 is kept out in circuit board 30 one side of infrared tube 25 dorsad, so, this groove 160 and this spacing preiection 165 can carry out spacing in the short transverse of the pipe 10 that filters to circuit board 30, prevent that circuit board 30 from moving up and down.
