Abstract
The utility model discloses an elevator door finger-nipping-preventing device which comprises a mounting base arranged between a front-wall door sleeve of an elevator car and a car door. A piezoelectric sensor is arranged on one side, opposite to the car door, of the mounting base. The output end of the piezoelectric sensor is connected with a car door controller through a wire. A signal trigger is arranged between the piezoelectric sensor and the car door. The elevator door finger-nipping-preventing device is short in response time, the car door can be stopped quickly, fingers of a child can be protected from damage, and the using safety of an elevator is greatly improved.
Description
Technical field
The utility model design elevator control field, relates to a kind of human body protection device that is located at lift car, particularly a kind of elevator door finger clipping-proof device.
Background technology
The application places of elevator is more and more extensive, and child is thoughtless, usually can be attached on elevator door by finger; because child points thinnerly, when opening the door, easily by elevator door, be drawn in crack, because gate is difficult to stop fast when the operation; cause child to point injury, this type of accident also often occurs.
Utility model content
The purpose of this utility model is, a kind of elevator door finger clipping-proof device is provided.It can stop fast the motion of gate when child's finger is pulled by elevator door, avoids child to point and comes to harm.
The technical solution of the utility model: a kind of elevator door finger clipping-proof device, comprise and be located at the antetheca door pocket of lift car and the mount pad between gate, a side relative with gate on mount pad is provided with piezoelectric transducer, the mouth of piezoelectric transducer connects car door controller through wire, between piezoelectric transducer and gate, is provided with signal trigger.
Aforesaid elevator door finger clipping-proof device, described signal trigger comprises the rocking bar being connected with mount pad through connecting rod, and the surface, upper right of rocking bar is provided with and the corresponding contact of piezoelectric transducer, and the surface, upper left of rocking bar is provided with the spring being connected with mount pad.
Compared with prior art, the utility model has formed a kind of elevator door finger clipping-proof device by " being located at the antetheca door pocket of lift car and the mount pad between gate; a side relative with gate on mount pad is provided with piezoelectric transducer; the mouth of piezoelectric transducer connects car door controller through wire, is provided with signal trigger between piezoelectric transducer and gate " organic linking together of these technical characterictics.Owing to having adopted above-mentioned technical scheme, when being drawn in crack by elevator door, child's finger makes to press on signal trigger piezoelectric transducer, the current potential of piezoelectric transducer changes, and signal is spread out of to elevator cage door controller, it is out of service that elevator cage door controller judges control gate.The time of the utility model response is very short, in the time of fast, gate is stopped, and avoids child's finger to come to harm, and has greatly improved the safety that elevator is used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the signal trigger in Fig. 1.
Being labeled as in accompanying drawing: 1-gate, 2-antetheca door pocket, 3-piezoelectric transducer, 4-rocking bar, 5-contact, 6-mount pad, 7-connecting rod, 8-spring, 9-rotating shaft.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of elevator door finger clipping-proof device, form as shown in Figure 1 and Figure 2, comprise and be located at the antetheca door pocket 2 of lift car and the mount pad 6 between gate, a side relative with gate 1 on mount pad 6 is provided with piezoelectric transducer 3, the mouth of piezoelectric transducer 3 connects car door controller through wire, between piezoelectric transducer 3 and gate 1, is provided with signal trigger.
Signal trigger comprises the rocking bar 4 being connected with mount pad 6 through connecting rod 7, and the surface, upper right of rocking bar 4 is provided with and the corresponding contact 5 of piezoelectric transducer 3, and the surface, upper left of rocking bar 4 is provided with the spring 8 being connected with mount pad 6.
Rocking bar 4 is connected with connecting rod 7 by rotating shaft 9.
Principle of work of the present utility model: make to press on signal trigger piezoelectric transducer when child's finger is drawn in crack by elevator door, the current potential of piezoelectric transducer changes, and signal is spread out of to elevator cage door controller, it is out of service that elevator cage door controller judges control gate.The time of the utility model response is very short, in the time of fast, gate is stopped, and avoids child's finger to come to harm, and has greatly improved the safety that elevator is used.
