Description

The metal edge frame that a kind of large scale infrared touch panel is used

Technical field

The utility model relates to the infrared touch panel field, and especially the metal edge frame of using with a kind of large scale infrared touch panel is relevant.

Background technology

Use infrared touch panel in order to be engaged on the different display screens, many factories have all developed the infrared touch panel frame of a series of specifications, to tackle different user's needs, yet the size of this class frame is fixed, therefore just need different moulds to support, can significantly increase production cost undoubtedly, all the more so for large-sized touch-screen, not only develop the cost costliness of big mould, have problems especially aspect production, the transportation.

In order to address the above problem; Open (bulletin) number is: the utility model patent of CN2807333 discloses a kind of shape frame that is used for infrared touch panel, purpose is to solve the problem that needs different moulds at the touch-screen of different size, they adopt the shape of U type to make frame, the opening of section bar is exactly ultrared light inlet window in fact, be coated with optical filter on the light inlet window, circuit board just is installed in the cavity of shape, one side near display screen has handle hole when mounted, only in cavity, finish the installation of touch-screen by this slight handle hole, location and debugging can bring very many inconvenience and difficulty, install, also handle hole to be covered after debugging finishes, will cause the surface irregularity of frame like this; Influence the overall appearance of touch-screen, if handle hole is poorly sealed, nature can influence the sealing effectiveness of touch-screen.And also will bring many troubles for service work in the future.

Summary of the invention

Technical problem to be solved in the utility model is the fault of construction that overcomes existing large scale infrared touch panel frame, thereby provides a kind of compact conformation, Installation and Debugging, maintenance conveniently, the metal edge frame that good airproof performance and large scale infrared touch panel attractive in appearance are used.

In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals: being linked to each other by 4 identical bullion section bar two ends of shape of cross section is spliced into a rectangular shaped rim, this bullion section bar is complementary to snap in by upper casing and lower casing and is formed by connecting and forms an energy containment circuit board and welding infrared emission, the cavity of receiving tube array thereon, and a side of this cavity offers and the workplace of infrared emission, receiving tube array light hole one to one.As preferred version:

Described two adjacent bullion section bar two ends are the miter angle inclined-plane or are the plane splices the L-shaped right angle of the shape of faying face mutually; Its screw is fixedly connected in splicing place by the angle contiguous block.

Described light hole is to be opened on the side of upper casing, and within it on wall or the outer wall, is pasted with can see through infrared ray and the optical filter of blocking visible light is as the criterion to cover light hole fully.The bullion section bar of described composition rectangular shaped rim is an aluminium alloy extrusions.

Described lower casing is provided with some screw locating slots and the angle contiguous block is located by connecting by screw.Upper casing one side of described bullion section bar offers a groove and is complementary to snap in boss that lower casing one side is offered and is connected.

The inherent light hole of the upper casing of described bullion section bar top also is provided with the installing and locating that the guide rail that is provided with on a slideway and the lower casing is used for circuit board on same surface level.

Owing to adopted above-mentioned technical scheme; The metal edge frame that the large scale infrared touch panel that the utility model provides is used has the following advantages: first: thus owing to used the shape material to simplify the design and the manufacturing of product mold, go the splicing of cutting shape to get final product according to the size of user's needs.Second: structural design of lower casing combination is very ingenious, compact on it, make things convenient for the Installation and Debugging and the maintenance of touch-screen, good airproof performance and attractive in appearance, the the 3rd: because the frame of touch-screen is to be spliced from beginning to end by 4 section bars, need to arrive the on-the-spot splicing assembling in user location if having, thereby avoid the problem of large scale touch-screen transportation inconvenience.
