Description
Technical field
The utility model relates to elevator light curtain technical fields, more particularly to a kind of double protection elevator light curtain.
Background technique
Common light curtain item can only be the transmitting that signal is carried out by the infrared mutual-tube in light curtain, when elevator work
It waits, when user has blocked the signal of a part of infrared mutual-tube, the signal that elevator door will receive phase down and be again turned on,
This common elevator light curtain have the shortcomings that it is certain, when elevator light curtain damage when, elevator door can not carry out pinch resistant operation, make
At certain security risk, simultaneously because the thickness of elevator light curtain is less than elevator thickness gate, when shelter contacts elevator door edge
But when not blocking infrared mutual-tube, elevator door still will do it closure, so that shelter is pressed from both sides, cause certain safety hidden
Suffer from.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of double protection elevator light curtain, simple with structure,
The spies such as security performance that are easy to assembly, making light curtain that there is double protection measure, substantially increase light curtain by arranging rubber strip
Point.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of double protection elevator light curtain is provided,
Including transmitter, receiver and transmitter infrared mutual-tube, the transmitter and receiver structure in long strip, transmitter
It is installed relatively with receiver in vertical, is separately installed with transmitter infrared ray pair inside transmitter and receiver opposite side one end
Pipe and receiver infrared mutual-tube are arranged with strip aluminium alloy fixing piece on transmitter and the receiver opposite side other end,
Two strip aluminium alloy fixing pieces are mounted on rubber on opposite side in dislocation arrangement, two strip aluminium alloy fixing pieces
Two metal tapes have been mounted side by side in hollow portion in adhesive tape, the rubber strip inner hollow, and the metal tape, transmitter are red
Outside line is connected to pipe and receiver infrared mutual-tube with signal receiver.
Described rubber strip one end, which is caught in, is mounted on strip aluminium alloy fixing piece, and the other end is in cylinder strip structure, column
Rectangular hollow is disposed in strip structure.
The side of the strip aluminium alloy fixing piece installation rubber strip is disposed with open slot, the open end court of open slot
The lateral middle of rubber strip extends, and is embedded into rubber strip.
The utility model has the advantages that the utility model relates to a kind of double protection elevator light curtain have structure it is simple, it is easy to assembly, pass through
The security performance that arrangement rubber strip makes light curtain have the characteristics that double protection measure, substantially increase light curtain.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiments of the present invention is related to a kind of double protection elevator light curtain, as shown in Fig. 1-3, including transmitter
1, receiver 2 and transmitter infrared mutual-tube 3, the transmitter 1 and the structure in long strip of receiver 2, transmitter 1 and connect
Device 2 is received in vertical opposite installation, transmitter 1 and receiver are separately installed with transmitter infrared ray pair inside 2 opposite side one end
Pipe 3 and receiver infrared mutual-tube 4 are arranged with strip aluminium alloy on the 2 opposite side other end of transmitter 1 and receiver and fix
Part 5, two strip aluminium alloy fixing pieces 5 are pacified on opposite side in dislocation arrangement, two strip aluminium alloy fixing pieces 5
Equipped with rubber strip 6, two metal tapes 7, the metal tape has been mounted side by side in hollow portion in 6 inner hollow of rubber strip
7, transmitter infrared mutual-tube 3 and receiver infrared mutual-tube 4 are connected with signal receiver.
Described 6 one end of rubber strip, which is caught in, is mounted on strip aluminium alloy fixing piece 5, and the other end is in cylinder strip structure,
Rectangular hollow is disposed in column strip structure.
The side that the strip aluminium alloy fixing piece 5 installs rubber strip 6 is disposed with open slot, the open end of open slot
Lateral middle towards rubber strip 6 extends, and is embedded into rubber strip 6.
Embodiment
What rubber strip 6 selected is the soft rubber material easily deformed, and rectangular hollow, rectangular hollow two are disposed in rubber strip
Two metal tapes 7 are separately installed in end, when rubber strip 6 is not squeezed, two metal tapes 7 are in separation shape
State, when rubber strip 6 is crushed, two metal tapes 7 can generate contact, give elevator door one signal for having shelter,
So that elevator door phase down, and elevator door is opened, which is mainly used to play the role of double protection, infrared when script
When line breaks down to pipe 3, can effectively avoid elevator door press from both sides people the case where, considerably increase the safety coefficient of elevator.
When producing this light curtain, the open slot of the strip aluminium alloy fixing piece 5 of selection is embedded into rubber strip 6,
It can effectively avoid rubber strip 6 from falling off, improve service life.
