The shifting fork is movably fixed to the door panel by a stationary shaft and is movably connected with the connecting rod for a plug, the raised in inserted in a hole of a cross rod of the connecting rod for a plug and the locking pawl is connected to one end of the connecting rod for a plug. The locking device can also be provided with a cipher control device, and has excellent safeness.
Description
The utility model belongs to a kind of locking device on the security door.
Because aspects such as the condition of public security is not good enough settle the people of security door more and more, and existing security door generally connect a common door lock as locking device at the one face down bonding, its advantage is simply to be easy to do, its shortcoming then be insecure, feel unwell complete.A kind of board-like security door (CN96234756.6) of applicant invention has in the past been done some improvement to lockset etc., and safety increases, but still not very good.
The purpose of this utility model is to create a kind of firm locking device, the locking of four limits, and have crypto control unit.
The purpose of this utility model is achieved in that it mainly is made up of door-plate, doorframe, lock, lock pawl, hinge, be characterized in that this has designed a four-way interlocking mechanism, this interlocking mechanism is made up of the plush copper on plug connecting rod, shift fork, fixed axis and the door lock, shift fork is fixed on the door-plate with the fixed axis activity, shift fork and plug connecting rod flexibly connect, plush copper is through in the hole of cross bar, and the lock pawl is connected an end of plug connecting rod.Lock time lock pawl opens.
This locking device can be provided with cipher control mechanism, that is: the plug connecting rod is provided with block, and its top also is provided with scrambler, rolling gate door lock, scrambler and matches with rolling gate door lock.
The lock pawl is made up of train wheel bridge, left gear piece, right gear piece, rivet or screw and lower plate, and the quantity of lock pawl is 1-8.
The utility model has the advantages that safe and reliablely, braking flexibly can be provided with cipher control switch or the like.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is a transmission mechanism schematic diagram of the present utility model
Fig. 2 is an A-A sectional view of the present utility model
Fig. 3 is lock pawl (gear piece open configuration) front view
Fig. 4 is lock pawl (gear piece open configuration) upward view
Fig. 5 is lock pawl (gear piece closure state) front view
As shown in Figure 1, 2, security door locking device mainly is made up of door-plate 1, doorframe 2, door lock 3, hinge 5, lock pawl [4], and door-plate 1 is fixed on the doorframe 2 by hinge 5 activities, and door lock 3 is loaded on door-plate one side; Be characterized in having designed in this door-plate a four-way interlocking mechanism, this interlocking mechanism is made up of the plush copper 31 on plug connecting rod 11, shift fork 12, fixed axis 13 and the door lock 3,11 activities of shift fork 12 usefulness fixed axis are fixed on the door-plate 1, shift fork 12 flexibly connects with plug connecting rod 11, plush copper 31 is through in the hole of cross bar 111, and lock pawl 4 is connected an end of plug connecting rod [11].Door-plate 1 is a plate body of making a thin boxlike with iron sheet outer casing 17, and four-way interlocking mechanism and lock core are hidden in the box body.
This lock can be provided with a cipher control mechanism, that is: plug connecting rod 11 is provided with block 16, and its top is provided with scrambler 14, rolling gate door lock 15, and scrambler matches with rolling gate door lock 15.
Shown in Fig. 3,4,5, lock pawl [4] mainly is made up of train wheel bridge 44, left gear piece 41, right gear piece 45, rivet or screw [42] and lower plate 46, left and right gear piece 41,45 activity respectively is fixed between the upper and lower clamping plate 44,46, and upper and lower clamping plate are fixing with rivet or screw 42.This lock pawl 4 quantity are 8 altogether, promptly on each plug connecting rod work are housed.Can optionally load onto an amount of lock pawl.
Transmission mechanism is work like this: the people is driving plush copper 31 motions on the lock cores 19 by key or the indoor turn-knob 18 that passes through outdoors, plush copper drives cross bar 111, cross bar affects plug connecting rod 11 again, plug connecting rod pulling shift fork 12, shift fork drives the jack that other three plug connecting rods inject doorframe simultaneously, four-way lock pawl opens simultaneously, and door leaf is locked on the doorframe, and whole braking procedure is the while, synchronous.In addition, just locking of door.Otherwise door is opened.
If start cipher control mechanism, then password to the time, (leaving block 16) shunk at rolling gate door lock 15 two, at this moment, plug connecting rod 11 retractables.Otherwise, then be stuck.
