Description

The improvement of door lock arrangement

Technical field

The design is a kind of improvement of door lock arrangement, is particularly improved structure at a kind of door lock that is installed in fire prevention double door fixation side door leaf.

Background technology

Be divided into fire district for the fire safety dividing regions in the at present general building building, wherein at interval fire district position and the fire prevention double door that is provided with, all be equiped with door lock lock control double door wherein a side fixedly door leaf close and be located on the doorframe, stop the diffusion of scene of a fire flame and produce the fire prevention function of use by door leaf.As first, fire prevention double door door lock commonly used shown in two figure mainly has the sliding bar 2 that can slide up and down, the top of this sliding bar 2 is connected with a locking bolt 7, bottom socket one spring 5 of sliding bar 2, be provided with mobile drive bar 4 in parallel and be positioned at sliding bar 2 one sides, this drives another parallel spring 6 of spring 5 of bar 4 central authorities sheathed one and above-mentioned sliding bar 2, drive bar 4 one ends by interlock plate 3 with sliding bar 2 interlocks, one end of this drive bar 4 connects a cam 9, when the swing leaf of fire prevention double door is shut, get final product in the oscillating cam 9 interlock locking bolts 7 retraction door locks, simultaneously interlock should drive bar 4 and with sliding bar 2 toward the top pushing tows, make locking bolt 7 stretch out upward locking plate outside, the double door fixation side of so will preventing fires door leaf locked establish fixing.Yet the fire prevention double door door lock that this kind is commonly used has following use defective:

(1) drives bar 4 one ends in the aforementioned fire prevention double door door lock commonly used and connect a cam 9, strength actuating cam 9 swings by a dead bolt 8 retraction door locks, one end of this cam 9 produces the action of upwards steeving makes drive bar 4 to top offset, analyze the whole process of cam 9 stressed swing displacements, it is smoothly smooth and easy inadequately to find that cam 9 moves, be easy to generate the slip component of horizontal direction, make cam 9 be subjected to bigger horizontal direction load, therefore very unfavorable to the transmission running of whole element, these cam 9 easy wearing and tearing are often broken down, and cause door lock shortening in application life.

(2) Chang Yong fire prevention double door is when the door lock locking, the top and bottom of fixation side door leaf set firmly and can't open because of locking bolt 7 stretches in the locking bolt hole of doorframe respectively, but meet emergency and must open the fire prevention double door rapidly for evacuating personnel, promptly must remove its blocking to the last door lock of fire prevention double door device one by one with following door lock respectively, can open the fire prevention double door, consider under the requirement of seizing every minute and second in the time, fire prevention double door door lock commonly used is to have the door leaf of unlatching to use defective inadequately rapidly.

The utility model content

The design's a purpose is to provide a kind of door lock arrangement of the double door of preventing fires, and can make the more level and smooth smooth and easy action of each element, reduces failure situations and takes place, thereby increase the application life of door lock.Another purpose of the design, when being to make the door lock blocking of fire prevention double door, must open door leaf rapidly, can a push action can open door lock rapidly and open door leaf simultaneously if meet the state of emergency, process is very rapid easily, meets the security against fire standard of fire prevention escape.

The improvement of a kind of door lock arrangement that the design provides comprises that one is installed in the jam plate of fire prevention double door side, this jam plate central authorities interlocking one fixed support, and this fixed support is provided with two guide holes, can be for the vertical up and down slippage of guiding one slide bar; The junction plate of one rectangular shaped slidably is located at support bracket fastened lower end, and the affixed slide bar of junction plate upper end one side, and the affixed locking bar of bottom one side can make the synchronous upper and lower displacement of slide bar and locking bar slide;

One lock bar seat is a shaped as frame pedestal, and interlocking is in the bottom position of jam plate;

Above-mentioned lock bar seat upper end end face is established a guide hole, can stretch in the lock bar seat for a locking bar bottom, this lock bar seat inside is installed with a slide that can move forward and backward, the dual-side that wherein is positioned at slide is respectively established one and is faced upward the skewed slot of stretching to left upper end, respectively establish the chute of a vertical direction with respect to the dual-side of lock bar seat, and the locking bar bottom of stretching in the lock bar seat plugs a locking bar pin, and the two ends of locking bar pin are protruding from the chute of the skewed slot of slide and lock bar seat respectively.

The locking bar bottom of wherein stretching into lock bar seat plugs a locking bar pin, the front end of this locking bar tip is established a teat, the other end is provided with a groove, the end that the locking bar pin is established groove stretches out Hou by the skewed slot of slide one side and the chute of lock bar seat one side respectively, be embedded a C type clasp in groove, the locking bar that plugs the locking bar tip is connected on the slide that is installed with in lock bar seat.

The slide right-hand member that wherein is installed with in the lock bar seat is established a pressing body, establishes a circular hole with respect to this position of jam plate, can stretch into the promotion pressing body for operator finger, make slide in lock bar seat to preceding slippage.

Fixed support upper side is wherein established a tip body, but the upper end of snapping one flexible member, the bottom of this flexible member then be buckled in the junction plate side form recessed scalariform fastener portion on, this flexible member can produce a pulling force and make the junction plate slide displacement that makes progress.

For further understanding the design's characteristics and effect, be described with reference to the accompanying drawings as follows.
