Background technology
The platform region at station and roadway region are separated by subway shield door on whole platform length, and wait passenger and track can effectively be isolated by it, prevent because of crowded fall the generation of rail event and event of deliberately jumping onto the tracks.Electronic lock is the core component of sliding door of screen door, which comprises at least a lockable mechanism, electronic unlock mechanism, a hand-operating unlocking mechanism and is closed to position detecting mechanism.
Be closed to position detecting mechanism and generally comprise movable axis and travel switch, movable axis is arranged on the fixed part of electronic lock housing movably, the locking striking plate of sliding door is provided with inclined-plane, sliding door slope driving movable axis when closing is movable vertically, thus make movable axis touch the touching part of travel switch, whether close put in place to detect sliding door.
But there is following problem in existing testing agency: the first, the contact area of the touching part of movable axis and travel switch is less, and general contact portion only has single line, easily causes not reaching position; The second, the frictional force of movable axis and fixed part is excessive, causes easily stuck.Therefore cause sliding door to close to put in place, travel switch does not but trigger, and finally causes electronic lock fault rate in use high.Along with the extensive use of track traffic, and its long-time not interrupt run reason, just require that the installation and maintenance time requirement of electronic lock is shorter and shorter, fault rate requires more and more lower, and namely possibility requires high.Traditional electronic lock structure obviously cannot better serve new requirement.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of New shield door electronic lock, can effectively avoid movable axis and travel switch not to reach position and the stuck problem of movable axis.
For achieving the above object, the utility model adopts following technical scheme:
A kind of New shield door electronic lock, comprising:
Housing, this housing is installed with a substrate, and the inner side of this substrate is installed with a copper sheathing;
Be installed on the travel switch of enclosure interior, the side of the trip switch is provided with touching part, and this touching part is inclined upwardly to outside gradually by the inner side of travel switch;
Be located at the movable axis of touching part side, this movable axis is arranged in also can along the short transverse activity of housing in copper sheathing, the lower end that movable axis exposes outside housing is articulated with roller, the upper end of movable axis is provided with the first inclined-plane near the side of touching part, first inclined-plane is inclined upwardly from the inner side of travel switch gradually to outside, and the first inclined-plane is used for the top pressure touching part when movable axis moves upward;
Be fixedly arranged on the locking striking plate on sliding door, locking striking plate is located at hull outside, and locking striking plate is provided with the second inclined-plane that the pushing rolling wheels when sliding door is closed moves upward near the side of housing.
The trip switch is microswitch.
The inner side of this substrate is also installed with a stainless steel sleeve, and this copper sheathing to be fixedly arranged on inside stainless steel sleeve and coaxially to arrange with this stainless steel sleeve.
Movable axis is installed with collision block, and the first inclined-plane is located on collision block.
This New shield door electronic lock also comprises elastic mechanism, and this elastic mechanism is for providing the elastic force making movable axis move downward.
The beneficial effects of the utility model are:
Compared to prior art, second inclined-plane pushing rolling wheels when sliding door is closed of locking striking plate of the present utility model moves upward, thus drive movable axis to move upward, the first inclined-plane is made to contact with touching part and promote to touch part, because the first inclined-plane and touching part are all inclined upwardly from the inner side of travel switch gradually to outside, such contact area is larger, movable axis and travel switch can be effectively avoided not to reach the problem of position, and, the copper sheathing that material is softer is installed with inside substrate, movable axis is arranged in copper sheathing, can the frictional force that is subject to when up and down of less movable axis, thus prevent movable axis stuck.
