Adopt technique scheme, the utility model at least comprises following beneficial effect:
A kind of stair comb plate anti-clamping structure described in the utility model; be provided with photoelectric protector; if there is clothing to block; can cause photoelectric protector to open circuit; when if arbitrary photoelectric protector opens circuit, the receiving unit of described photoelectric protector cannot receive the photosignal that corresponding luminescence component sends, and control circuit feedback closing signal is to driving circuit; elevator is closed in time, protection passenger safety.By the improvement to meshing part, also can reduce the possibility that clothing is pressed from both sides by actv. simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of stair comb plate anti-clamping structure described in the utility model.
Fig. 2 is the circuit diagram of circuit control system described in the utility model.
Fig. 3 is meshing part constructional drawing described in the utility model.
Wherein: 1. ladder tread, 2. fishback, 3. luminescence component, 4. receiving unit, 5. control circuit, 6. driving circuit, 7. up photoelectric switch, 8. descending photoelectric switch, 9. corner, 10. fillet.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1 to Figure 2, for meeting a kind of stair comb plate anti-clamping structure of the present utility model, comprise ladder tread 1, fishback 2 and circuit control system, described ladder tread 1 is connected by meshing part with described fishback 2, described in each the below of fishback 2 and corresponding under be provided with a pair of photoelectric protector in the space of 1 of ladder tread, described a pair of photoelectric protector specifically comprises luminescence component 3 and receiving unit 4, described luminescence component 3 and described receiving unit 4 are arranged in respectively the both sides of the lower side space of described fishback 2, the light that described luminescence component 3 sends runs through the receiving end of the described receiving unit 4 of the rear aligning of whole described ladder tread 1.
Described circuit control system comprises control circuit 5 and driving circuit 6, the input end of described luminescence component 3 and described receiving unit 4 external control circuits 5, and the mouth of described control circuit 5 connects driving circuit 6.
The input end of described control circuit 5 comprises up photoelectric switch 7 and descending photoelectric switch 8, and described up photoelectric switch 7 connects the photoelectric protector that is positioned at staircase top, and described descending photoelectric switch 8 connects the photoelectric protector that is positioned at staircase bottom.
Described up photoelectric switch 7 and described descending photoelectric switch 8 are preferably correlation type photoelectric switch, and the transmitting terminal of described correlation type photoelectric switch receives the signal of described luminescence component 3, and the receiving end of described correlation type photoelectric switch receives the signal of described receiving unit 4.
Principle of the present utility model is when two equal paths of photoelectric protector; described control circuit 5 feedback normal signal are to described driving circuit 6; described driving circuit 6 is normally moved; when if arbitrary described photoelectric protector opens circuit; the described receiving unit 4 that is described photoelectric protector cannot receive the photosignal that corresponding described photoelectric subassembly sends; described control circuit 5 feedback closing signals are to described driving circuit 6, and described driving circuit 6 controls staircase and cuts out.If adopt the staircase of frequency conversion drive; when this photoelectric protector opens circuit, the approximately 10 second out of service time of staircase, then circuit control system can be controlled staircase and move about 25cm with extremely slow speed back; to be emitted by lined dress thing, and avoid the person to cause serious injury.Due to the common technology means that are designed to those skilled in the art of described driving circuit 6, and not innovative point of the present utility model place, so locate to repeat no more.
As shown in Figure 3, described meshing part is engagement in rotation parts, and described meshing part and described fishback 2 joint face corners 9 are greater than 90 degree, and the junction of described meshing part and described ladder tread 1 is fillet 10.We know that traditional meshing part and fishback 2 joint face corners are 90 degree, by can effectively reducing to the change of this angle the possibility that clothing is pressed from both sides.
Preferably the light of described luminescence component 3 gos deep into the inside 20cm of described fishback 2, and described luminescence component 3 is photo-electroluminescence head.The selection of above-mentioned luminescence component 3 and described light deep data are just selected in order to meet the user demand of general staircase and are set, those skilled in the art can carry out parts replacement and numerical value change completely according to actual needs, and the present embodiment does not limit this.
Stair comb plate anti-clamping structure described in the utility model; be provided with photoelectric protector; if there is clothing to block; can cause photoelectric protector to open circuit; when if arbitrary photoelectric protector opens circuit, the receiving unit of described photoelectric protector cannot receive the photosignal that corresponding luminescence component sends, and control circuit feedback closing signal is to driving circuit; elevator is closed in time, protection passenger safety.By the improvement to meshing part, also can reduce the possibility that clothing is pressed from both sides by actv. simultaneously.
Above an embodiment of the present utility model is had been described in detail, but the preferred embodiment that described content is only created for the utility model can not be considered to the practical range of creating for limiting the utility model.All equalization variations of doing according to the utility model creation application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
