The present invention relates to elevator mounting structure field, the present invention provides a kind of elevator doorway light curtain blind area safety guard, including entrance rubber, sensing button, installing plate；Entrance rubber includes elastic rubber and vulcanie, entrance rubber is arranged on the gate lower end at left and right sides of elevator doorway light curtain detection zone bottom, outermost layer wraps up vulcanie for elastic rubber, against sensing button on the inside of vulcanie, it is installing plate to sense on rear side of button, and installing plate is connected with gate door-plate.Beneficial effect of the present invention is that realizing elevator cage door processes simple, install convenient, the detection structure that mounting structure is stablized；By the light curtain blind area design sensing device in elevator doorway lower part, foreign matter discrepancy has been detected whether, while same sensing device is set on elevator doorway top, and then elevator doorway end is not produced any check frequency, ensure the safety of discrepancy elevator.
Description
Technical field
The present invention relates to elevator mounting structure field, and in particular to a kind of safety protection apparatus for elevator.
Background technology
Elevator doorway safety detection device currently on the market, locality can only be realized in foreign matter anti-pinch context of detection
Detection, can not realize the anti-pinch detection of sill all of the above region, i.e., there are security risk.Exist in major elevator field of employment
There is the situation that the foreign matters such as pet rope, kids toys drawstring, stone are clamped by elevator door to happen occasionally.
A kind of existing towed elevator safe inductive leveling device of patent of invention（Patent announcement CN206142573U）Announce
A kind of towed elevator safe inductive leveling device, comprising carriage, also comprising inductor.The object of the present invention is to provide one kind to drag
Draw elevator safety sensing leveling device, the accidental movement of elevator can be detected automatically, and carried out with standby brake apparatus and
When brake, increase elevator operation security.
Foregoing invention patent also has a drawback in that：Elevator doorway safety detection device can only realize the inspection of locality
Survey, can not realize anti-pinch, the foreign bodies detection in all of above region of sill.
The content of the invention
The object of the present invention is to provide the safety guard for preventing from occurring security risk at elevator entrance, solves elevator
Exit/entry security detection device can only locality detection sill more than subregion the problem of, while avoid pet rope,
The situation that the foreign matters such as kids toys drawstring, stone are clamped by elevator door occurs.
A kind of elevator doorway light curtain blind area safety guard proposed by the present invention, including entrance rubber, sensing are pressed
Button, installing plate；Entrance rubber includes elastic rubber and vulcanie, and entrance rubber is arranged on the detection of elevator doorway light curtain
Gate lower end at left and right sides of sections bottom, outermost layer wrap up vulcanie for elastic rubber, sensing are abutted on the inside of vulcanie
Button, sensing button rear side is installing plate, and installing plate is connected with door-plate.
The use principle of the present invention is that sensing button is arranged on light curtain check frequency, left and right door plate be respectively provided with sensing by
Button, when elevator doorway is closed, if there is foreign matter to enter light curtain check frequency, before elevator doorway completely closes, first with going out
Entrance rubber contact, compresses entrance rubber, and triggers sensing button, sends signal and prevents elevator car door system from continuing to close, and
Reopen entrance.
The elevator doorway light curtain blind area safety guard of the present invention has the beneficial effect that, by elevator doorway lower part
The sensing of light curtain blind area design whether have foreign matter discrepancy, while same sensing device is set on elevator doorway top, and then
Elevator doorway end is not produced any light curtain blind area, ensure the safety of discrepancy elevator.Rubber surface sets elastic rubber, tool
There is good cushioning effect, the configuration of the present invention is simple, installation and maintenance are convenient, of low cost.

Embodiment
Below in conjunction with the accompanying drawings with specific embodiment to the present invention elevator doorway light curtain blind area safety guard make into
The explanation of one step.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of elevator doorway light curtain blind area safety guard, including entrance rubber
Glue 13, sensing button 7, installing plate 6；Entrance rubber 13 includes elastic rubber 9 and vulcanie 8, and entrance rubber 13 is set
Gate lower end at left and right sides of elevator doorway light curtain detection zone bottom, at 1 reserved location of door-plate, outermost layer is elastic rubber
Glue 9 wraps up vulcanie 8, and for the inner side of vulcanie 8 against sensing button 7,7 rear side of sensing button is installing plate 6, installing plate 6 with
Door-plate 1 connects.Sensing button 7 in the present invention is normally closed type switch button, and the energy independent role of sensing button 7, senses at the same time
Button 7 has auto restore facility, it is necessary to certain pressure could trigger, and avoids button from malfunctioning；Sense the sensitivity of button 7
No more than 2mm, practical application effect can be effectively ensured.
Use principle：Sensing button 7 is arranged on light curtain check frequency, and left and right door plate 1 is respectively provided with sensing button 7, and elevator goes out
When entrance is closed, if there is foreign matter to enter light curtain check frequency, before elevator doorway completely closes, first and entrance rubber 13
Contact, compression entrance rubber 13, and sensing button 7 is triggered, send signal and prevent elevator car door system from continuing to close, and beat again
Output entrance.Beneficial effect：Sense whether have foreign matter discrepancy by the light curtain blind area design in elevator doorway lower part, while
Elevator doorway top sets same sensing device, and then elevator doorway end is not gone out to produce any light curtain blind area, protects
The safety of card discrepancy elevator.Rubber surface sets elastic rubber 9, has good cushioning effect, the configuration of the present invention is simple, installation
It is convenient with maintenance, it is of low cost.
The fully wrapped around vulcanie 8 of elastic rubber 9, elastic rubber 9 are equipped with step 12 at three.Elevator doorway rubber 13
During practical function, elastic rubber 9 is directly contacted with object, plays good cushioning effect, while elastic rubber 9 is equipped with three
Step 12, ensures to flush with entrance door-plate 1 during installation, plays tailored appearance, beautiful effect.
Installing plate 6 is connected with door-plate 1 by kind of a weldering bolt arrangement 11, and kind weldering bolt arrangement 11 includes kind of weldering screw 2, a plain cushion
Circle 3, spring washer circle 4, hex nut 5.In actual installation application, preferentially directly planted with installing plate 6 and door-plate 1 by kind of a weldering screw 2
Weldering, reduces installation difficulty.
Installing plate 6 is long lumbar hole with kind weldering 2 connecting hole of screw.So that installing plate 6 is when mounted, can one section of left and right adjusting away from
From guarantee sensing 7 installation site of button is rationally reliable.
13 installation gap of entrance rubber, and the screw 2 of installation kind weldering in advance are reserved on door-plate 1.Facilitate subsequent installation, and
Compared with standard door-plate 1, structure change is small, changing content is unified, convenient production, processing.
It these are only the preferred embodiment of the present invention, be not intended to limit the invention, come for those skilled in the art
Say, within the spirit and principles of the invention, any modification, equivalent replacement, improvement and so on, should be included in the present invention
Protection domain within.
