Abstract
The utility model discloses a soft-touch anti-collision clip-safe photoelectric device and consists of a shell body (5), a sensor bar made of rubber (1), a signal wire (4) and a sealed guide tube (2). A signal projector (6) and a signal receiver (3) are arranged on both ends of the sealed guide tube (2) respectively. The signal receiver (3) is connected with the signal wire (4). The signal projector and the signal receiver are an infrared light projector and an infrared light receiver respectively. The sensor bar is of a flat ribbon structure, and is made of flexible rubber and has a width of 50 to 100 millimeters. The sealed guide tube (2) is made of flexible material. The soft-touch anti-collision clip-safe photoelectric device of the utility model needs a weak contact force to acquire signals, provides a good protection to the aged, the young, the handicapped and the valetudinarian and has high sensitivity, stable working performance and powerful capability of resisting external interferences.
Description
Technical field
The utility model belongs to a kind of support device that is used for automatically-controlled door, especially a kind of anti-collision anti-pinch photoelectric induction device that guarantees human body safety.
Background technology
Present large automatic door, automatically-controlled door are a kind of dynamic rotation gates, main thoroughfare as personnel's turnover, its fail safe is particularly important, automatically-controlled door is in rotary course, if the pedestrian is contact-impact door body, particularly between revolving door body and fixed gate body, promptly in the share zone between inside door head and the external door head, will certainly cause personnel are injured.For the pedestrian is carried out safeguard protection, should opposite house implement that the anti-collision anti-pinch is emergent to stop security control, the accuracy of security control is except that control itself, key is the extraction and the acquisition of signal, thereby personnel are carried out anti-collision anti-pinch processing safely and effectively, reach this purpose, the induction installation that needs accurate sensitivity guarantees, and the existing automatically-controlled door that is used for, be installed in door pillar, movable door pillar and pivot region position, guarantee the anti-collision anti-pinch induction installation of human body safety, adopt mechanical type extruding on-off mode, be provided with the metal spring leaf switch in rubber strip inside, by the stressed extrusion metal reed switch of geometry special (purpose) rubber bar, the metal spring leaf switch is subjected to press contacts to produce signal, thereby plays the effect of safe anti-collision anti-pinch; But because the existence of rubber strip inner geometry form; rubber strip is stiff; it is big to obtain the needed contact force of signal; collision or clamping old man, children, disabled person and weak man-hour delay of response; protectiveness is poor, also exists the metal spring leaf oxidation in addition, influences such as rubber and the permanent deformation of metal spring leaf machinery; make this induction installation poor sensitivity in use, the service behaviour instability.
Summary of the invention
The utility model technical issues that need to address provide a kind of soft-touch type anti-collision anti-pinch photoelectric induction device; it is little that it obtains the needed contact force of signal, good to old man, children, disabled person and weak people's protectiveness, and highly sensitive; stable work in work, anti-external interference ability is strong.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of soft-touch type anti-collision anti-pinch photoelectric induction device, the induction bar and the holding wire that include housing, make by rubber, this induction installation also includes the sealing guiding tube, and is provided with signal projector and signal receiver at the two ends of sealing guiding tube, and above-mentioned signal receiver links to each other with holding wire.
Described signal projector and signal receiver are respectively infrared transmitter and infrared light receiver; Described induction bar is the plane banded structure, is made by soft rubber, and its width is 50～100mm; Described sealing guiding tube is made by soft material.
Owing to taked such scheme, the advantage that the utility model is compared with prior art had is:
1, owing to adopt soft induction bar, soft sealing guiding tube, reduced contact pressure greatly;
2, since the distortion of the different parts of induction bar can both disabling signal propagation path, and produce the useful signal of anti-collision anti-pinch, make that the sensitivity of device is very high;
3, because signal is propagated, be not subjected to extraneous any interference, reliability height, stable work in work in the sealing guiding tube.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The structural representation of Fig. 1 the utility model soft-touch type anti-collision anti-pinch photoelectric induction device.
Embodiment
As shown in Figure 1, the utility model soft-touch type anti-collision anti-pinch photoelectric induction device, the induction bar of making by housing 5, by rubber 1, holding wire 4, sealing guiding tube 2, signal projector 6 and signal receiver 3 are formed, this housing 5 is the cube structure of a side opening, opening part at housing 5 is provided with induction bar 1, and this induction bar 1 is the plane banded structure, is made by soft rubber, its width is 75mm, and the induction bar is with housing 5 sealings; Inboard at induction bar 1 is provided with the sealing guiding tube of being made by soft material 2, and also is provided with signal projector 6 and signal receiver 3 at the two ends of sealing guiding tube 2, and this signal receiver 3 links to each other with holding wire 4; Because the infrared light propagation velocity is fast, be not subject to outside electromagnetic interference, highly sensitive, so signal projector 6 and signal receiver 3 are respectively infrared transmitter and infrared light receiver.
The operation principle of the utility model soft-touch type anti-collision anti-pinch photoelectric induction device and course of work foot: this device is installed in the door pillar of automatically-controlled door, movable door pillar and pivot region position, start the infrared signal reflector then, Infrared normal propagation in the sealing guiding tube; When the pedestrian touches the induction bar by automatically-controlled door, deform after induction bar at first installing is stressed, the sealing guiding tube of being made by soft material in induction bar one side also can be crooked because of being squeezed, thereby blocked the normal propagation of Infrared, produce signal thus, get in touch, send instruction by control assembly by holding wire and automatically-controlled door control assembly (as computer), stop the operation of automatically-controlled door immediately, reach the effect of safe anti-collision anti-pinch.
As a kind of conversion of the utility model soft-touch type anti-collision anti-pinch photoelectric induction device, the width of above-mentioned induction bar is 50～100mm.
