Description
Technical field
A kind of tripper of the utility model especially relates to a kind of manual unlocking device that is used for horizontally sliding door.
Background technology
Horizontally sliding door is widely used in special places such as marquis's machine Room, airport, subway, light rail, and because of it uses frequently, usage quantity is big, and safety, the reliability of its door lock manual unlocking device proposed higher requirement.The manual unlocking device that uses adopts steel cord structure usually at present, and this tripper adopts the transmission medium of wire rope as moment.Wire rope long-time back of using under the pretightning force effect is elongated, very easily causes the not enough or release clamping stagnation of release stroke, thereby causes reliability to reduce, and the handle of most manual unlocking devices is external in addition, influences gauge and good looking appearance.Key lock is positioned at a body middle part, and artificially unlatching or destruction key lock are more or less freely, bring hidden danger to security of system.
Summary of the invention
The purpose of this utility model provides long sliding door manual unlocking device of a kind of simple in structure, safe and reliable, life-span.
For achieving the above object, the utility model is by the following technical solutions:
The utility model is provided with U type support in the doorframe upper inner of sliding door, and the upper and lower of U type support all has through hole, is inserted with push rod in the through hole; Push rod and last diagonal member flexibly connect, and the other end of last diagonal member and last pivoted arm flexibly connect, and last pivoted arm is connected with handle; Inboard, middle part at the doorframe of sliding door is provided with cell body, and handle is positioned at cell body; Between last pivoted arm and cell body, be provided with reduction torsion spring.
The above-mentioned pivoted arm of going up is connected with an end of following diagonal member, and the other end of following diagonal member links to each other with following pivoted arm, and following pivoted arm is connected with key lock.
Lower inside at U type support is provided with spacing collar.
Adopt the utility model of technique scheme, simple in structure, and be used for release parts such as push rod, go up diagonal member and last pivoted arm etc. and be rigid structures and link, use reliably, the life-span is long.In addition, handle separates with the key lock upper-lower position, and handle adopts concealed structure, saves installing space greatly.Key lock is positioned at a body bottom, the artificial malice that effectively prevents key lock is damaged, therefore have simple in structure, good looking appearance, use is reliable, the life-span is long advantage, occasion frequent, that security reliability requires high, a large amount of team control application level sliding doors is particularly suited for moving.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the left view of Fig. 2.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model is provided with U type support 3 in doorframe 14 upper inner of sliding door, fixedlys connected with doorframe 4 in the base of U type support 3, and its upper and lower all has through hole, be inserted with push rod 2 in the through hole, push rod 2 can slide up and down in the through hole of U type support 3.In addition, can be provided with spacing collar 4, be used for push rod 2 is carried out lower limit in the lower inside of U type support 3.Push rod 2 flexibly connects with last diagonal member 5, and the other end of last diagonal member 5 and last pivoted arm 9 flexibly connect, and last pivoted arm 9 is connected with handle 8, and can rotate with handle 8.Inboard, middle part at the doorframe 14 of sliding door is provided with cell body 6, and above-mentioned handle 8 just is positioned at cell body 6, has disguised well.Between last pivoted arm 9 and cell body 6, be provided with reduction torsion spring 7.
For realizing unlocking function better, in the utility model, last pivoted arm 9 can also be connected with an end of following diagonal member 10 simultaneously, and the other end of following diagonal member 10 links to each other with following pivoted arm 12, following pivoted arm 12 is connected with key lock 11, and can rotate with key lock 11.Key lock 11 is connected on the right angle rack 13, and right angle rack 13 is fixed on the body lower transverse frame 15.
Operating principle of the present utility model is as follows: when carrying out manual unlocking, can turn an angle in the direction that a side uses handle 8 to open along the door bodies, by the last pivoted arm 9 that links to each other with handle 8 drive upward angle ejector rod 5 and push rod 2 disk 1 is made progress jack-up one segment distance can be with top locking device release.Promote sliding door immediately and move horizontally the realization manual unlocking.Under the effect of reduction torsion spring 7, can recover reset condition again.
In like manner, can turn an angle in the direction that opposite side uses private key to open along the door body, upwards jack-up one segment distance can be with top locking device release with disk 1 to drive following angle ejector rod 10, last angle ejector rod 5 and push rod 2 by the following pivoted arm 12 that connects with key lock 11.
