The plastic cement combined type touch panel
Technical field
The utility model relates to a kind of touch panel, is the device that a kind of sportsman of judgement puts in place.
Background technology
The sportsman is through realizing timing or the detection that the sportsman is put in place to the touching of touching the limit that is arranged on the swimming lane two ends in swimming contest.Therefore, as the critical component of swimming contest self-clocking system, the designing requirement of touching the limit is quite high, need the bigger spray not reacted, but should can both detect the slight touching of sportsman.For a long time, touch the technology of making on the limit and all grasp abroad in producer's hand, cost is high.In addition, external product is based on the design of the electromechanics of complicacy, and node is many, safeguards loaded down with trivial detailsly, and maintenance period is lacked.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure, plastic cement combined type touch panel that cost is low, and this touch panel is non-maintaining, and result of use is also relatively good.
The utility model adopts following technical scheme:
A kind of plastic cement combined type touch panel of this utility model; Comprise and touch the limit assembly; Comprise that also frame constitutes the vulcanie plate of accommodating chamber with frame with being engaged in four limits in the frame; Wherein accommodating chamber is used to hold the said limit assembly that touches, and this to touch the limit assembly be watertight construction, draw from the edge in lead-in wire watertight feud.
The beneficial effect of the utility model is that the limit of touching based on watertight construction is provided with the vulcanie plate; This rubber slab passive movement person touches with the spray; Because the active area of the spray is big, unit pressure is little, and just pressure is smaller; Deficiency is not touched the limit so that the vulcanie plate produces local deformation thereby can not set out.And athletic shake-up then can produce bigger pressure in the part, and just local pressure is bigger, thereby makes rubber produce distortion, touches the function that switch is accomplished on the limit.
According to said structure, simple in structure, just in rubber slab machine frame, be provided with and touch the limit, only be several range upon range of parts, with low cost, simultaneously, employed component costs is also lower, also is not easy to be destroyed, and belongs to theoretic non-maintaining device.
Above-mentioned plastic cement combined type touch panel saidly touches the edge element that touches that the limit assembly comprises that pairing uses, and each touches edge element and comprises conductive metal foil and be bonded in the conductive rubber particle on this conductive metal foil.
Above-mentioned plastic cement combined type touch panel, the said limit assembly that touches is a rubber sealing structure.
Above-mentioned plastic cement combined type touch panel, said frame is the inboard aluminium section bar framework that has caulking groove.
Above-mentioned plastic cement combined type touch panel, said caulking groove form Back Word type structure on each frame.
Description of drawings
Fig. 1 is the structure principle chart of a kind of plastic cement combined type touch panel of the utility model.
Among the figure, 1, frame, 2, the vulcanie plate, 3, touch the limit assembly.
Embodiment
Term: touch the limit and be widely used in occasions such as lathe, automobile, whether close, touch the limit through safety to be detected by pressing like automotive door; For lathe mainly is to prevent that personnel from crushing injury, and at moving components such as movable tables, safety perhaps is set on some fixed part touches the limit; Through seeing off of switching value; Trigger relevant alarm appliance,, be called as safety and touch the limit with protection workman operation; Its structural principle also is the same with the common limit of touching, and all is the parts that play switching function.
In order to sharpen understanding; Touching the limit with safety is that example is explained the switching function that touches the limit; Safety is touched the limit and is generally comprised safe edge and safety buffer; And necessary package parts, be flexible bent ribbon, can be fixed on such as existence such as platen and Electrically operated gate and push and shear on the arris of dangerous moving-member.Will be oppressed and transmit signal and give power source as strike these flexible safe edges of operator's (or the operator strikes moving-member) when the moving-member that safe edge or safety buffer be housed to stop the motion of these parts.
The switching function on limit is touched in application; With reference to Figure of description 1, a kind of plastic cement combined type touch panel comprises and touches limit assembly 3; Comprise that also frame 1 constitutes the vulcanie plate 2 of accommodating chamber with frame with being engaged in four limits in the frame; Wherein accommodating chamber is used to hold the said limit assembly 3 that touches, and this to touch the limit assembly be watertight construction, draw from the edge in lead-in wire watertight feud.Like this, just can realize accomplishing switching function, see switching signal off, judge that the sportsman arrives or leaves touching the extruding on limit through shake-up to the vulcanie plate.
The structure kind of touching the limit is various, based on a kind of structure of water-stop does, saidly touches the edge element that touches that limit assembly 3 comprises that pairing uses, and each touches edge element and comprises conductive metal foil and be bonded in the conductive rubber particle on this conductive metal foil.
Conductive rubber is that conductive particle such as glass silvering, aluminium is silver-plated, silver is evenly distributed in the silicon rubber, makes the conductive particle contact through pressure, reaches excellent conducting performance.Its conventional purposes is that it mainly acts on is to seal and electromagnetic shielding military and commercial application arranged all.In this programme, constitute the contact, draw, form and touch the limit structure through conductive metal foil.Conductive metal foil preferably adopts Copper Foil, and resistivity is low.
The said limit assembly 3 that touches is rubber sealing structure, and is simple in structure, is convenient to make.
Install for ease, said frame is the inboard aluminium section bar framework that has caulking groove, and this structure also is convenient to processing.
Said caulking groove forms Back Word type structure on each frame, can further reduce difficulty of processing, simultaneously, is convenient to inlaying of vulcanie plate.
