Description
Technical field
The utility model relates to elevators field, particularly a kind of elevator light curtain refracting means.
Background technology
In recent years, the accident about elevator was in the news repeatedly, caused and paid close attention to widely.Wherein in order to avoid elevator door is to the potential threat of passenger, the safe operation of protection elevator car door system self, according to concerned countries standard " GB7588-2003 elevator manufacture with install safety standard ", the various forms of elevator door protection system of elevator design.In elevator, technology for preventing elevator from hurting passenger in door closing procedure mainly contains two kinds: 1, safety edge fender guard, specifically in elevator cage door both sides, safety edge fender guard is installed, when elevator is in door closing procedure, once have passenger or goods in elevator door switch door scope, first can touch safety edge, the heavy door open command of safety edge action triggers elevator, makes elevator door reopen; 2, elevator light curtain fender guard; wherein elevator light curtain fender guard is made up of infrared transmitter and infrared remote receiver; be contained in the both sides of elevator cab door respectively; when elevator is at closing time; goods or passenger is had to pass through within the scope of Ruo Men district switch gate; goods or passenger will block the infrared ray of light curtain fender guard thus trigger the heavy door open command of elevator, thus elevator door is reopened.
But find in practice process; with reference to Fig. 1; because light proscenia is arranged on the interlayer of elevator door usually; cause its protected zone can only shield at centre portion; namely the side, front and back of light proscenia has blind area 8; the sensitivity of impact monitoring, causes still likely clipping to goods or passenger when elevator door closing.A designer proposes an improvement project to this, concrete application reference number is the patent " reflective single-light source door " of 200710069212.5, wherein propose to coordinate light-emitting device to improve the number of times of light roundtrip by reflecting barrier, but the appearance of blind area can not be avoided.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of elevator light curtain refracting means.
The utility model solves the technical scheme that its technical matters adopts:
A kind of elevator light curtain refracting means, comprise point elevator door being listed in both sides, car front end, described elevator door comprises light curtain, is positioned at the Room gate layer of light curtain front end and is positioned at the gate layer held on light backstage, described elevator door comprises the corner reflector of the transmitting terminal front and rear sides being arranged on light curtain, the reflecting surface of wherein said corner reflector is towards the plane of symmetry direction of both sides elevator door, and the end of described Room gate layer and gate layer is respectively arranged with flat reflector.
As a preference, the vertical line of the reflecting surface relative elevator door of described corner reflector becomes 25 °.
As a preference, described transmitting terminal comprises and is uniformly distributed multipair power valve and adoptor from top to bottom.
As a preference, the upper and lower side of described transmitting terminal is respectively arranged with auxiliary angle catadioptre.
The beneficial effects of the utility model are: this elevator light curtain device is by rational structural improvement; particularly by newly-designed refracting means, to the light reflection of light curtain, cover unborn light curtain blind area; make the monitoring and protecting range extension of light curtain, effectively avoid elevator door to clip to object or person.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the birds-eye view of prior art;
Fig. 2 is birds-eye view of the present utility model;
Fig. 3 is the enlarged drawing of a-quadrant in Fig. 2;
Fig. 4 is the front view of light curtain part in the utility model.
Detailed description of the invention
With reference to Fig. 2 ~ Fig. 4, a kind of elevator light curtain refracting means, comprise point elevator door 1 being listed in both sides, car front end, described elevator door 1 comprises light curtain 2, be positioned at the Room gate layer 3 of light curtain 2 front end and be positioned at the gate layer 4 of light curtain 2 rear end, before described elevator door 1 comprises the transmitting terminal 5 being arranged on light curtain 2, the corner reflector 6 of rear both sides, the reflecting surface 61 of wherein said corner reflector 6 is towards the plane of symmetry direction of both sides elevator door 1, the end of described Room gate layer 3 and gate layer 4 is respectively arranged with flat reflector 7, the light of flat reflector 7 to light curtain 2 is coordinated to reflect by corner reflector 6, the protection domain of light curtain is expanded, the light curtain blind area occurred in original technology is also covered, make elevator safer.The vertical line of the reflecting surface 61 relative elevator door 1 of described corner reflector 6 becomes 25 °, and the reflection efficiency of the corner reflector 6 of this design is best, and avoids the situation of monitoring by mistake.
With reference to Fig. 4; described transmitting terminal 5 comprises and is uniformly distributed multipair power valve 51 and adoptor 52 from top to bottom; transmit-receive tube is opened according to this; continuous scanning gate region from top to bottom; form an intensive protection light curtain; under the prerequisite not needing too much transmitter and receiver, ensure monitoring effect, wherein power valve 51 and adoptor 52 can adopt infrared tube.The upper and lower side of described transmitting terminal 5 is respectively arranged with auxiliary angle catadioptre 61, to stop or reflect near IR shortwave is propagated towards sill direction.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
