Description

Many horizontal bolt door locks

Technical field

The utility model belongs to door lock, particularly the door lock field of double door.

Background technology

The comparatively common biparting door lock in the rural area, two root posts are contained in respectively on the equal height of two fan doors, when locking a door a horizontal bolt are penetrated in the preformed hole on two root posts to stop door leaf to be opened.Structures such as sprocket wheel or gear have been designed on some door locks with the operation of door of conveniently unblanking.But owing to have only a horizontal bolt, the insufficient strength of lock is still ruined the accident that lock opens the door easily.

Summary of the invention

The technical problems to be solved in the utility model is: reinforce lock body, the theftproof performance of enforced lock.

The utility model solves the problems of the technologies described above with following technical scheme: horizontal bolt 3 is fixedlyed connected with montant 4, montant 4 and horizontal bolt 6 pin joints; Lock core 12 is fixedlyed connected with shift fork 13, and the shift fork both sides have last arm-tie 11 and lower pulling plate 15 respectively, and there is stop 7 last arm-tie upper end, and there is stop 18 the lower pulling plate lower end; Last arm-tie top also has removable pin 20, and removable pin can be slidingly connected with the linkage of closing the door.

How horizontal the horizontal bolt intensity of bolt door lock of the present utility model is big, and lock body is reinforced, and external force is difficult for severing, and makes the anti-theft feature of lock good, and easy to operate, and cost of manufacture is low, very is suitable for the double door in vast rural area, and market prospects are wide.

Description of drawings

Fig. 1 is the structural representation of the how horizontal bolt door lock of the utility model.This figure is door lock with the two horizontal bolts state when door is closed.

The specific embodiment

Horizontal bolt 3 is fixedlyed connected with montant 4, and montant 4 is connected with horizontal bolt 6 by pin 5; The preformed hole that allows horizontal bolt to pass is arranged on the column 1 and 2, lock core 12 is fixedlyed connected with shift fork 13, the shift fork both sides have last arm-tie 11 and lower pulling plate 15 respectively, between last arm-tie 11 and shift fork crank 14 is arranged, last arm-tie is connected with stop 7 by upper connecting rod 8, universal joint 9, and lower pulling plate is connected with stop 18 by lower link 16, universal joint 17.Be fixed on the cylindrical pair 19 that resets on lock body 10 tops, spring and straight pin 20 are wherein arranged, the groove that can supply stop 21 to penetrate is arranged on the pin.The linkage of forming by rod member 22,23,24,25,26 that drives that stop 21 moves up and down.The bottom of lock has can be by the sprocket wheel 27 and the chain 28 of handle 29 rotations, and the chain end has reset baffle block 31.

When lock dress on door, two root posts be installed in respectively two fan doors etc. on the high position, horizontal bolt penetrates the preformed hole of column respectively.When door lock is in as shown in Figure 1 state, if will open the door, after key inserts the lock core keyhole, rotate by counter clockwise direction shown in Figure 1 earlier, shift fork 13 is stirred crank 14 and is rotated in the direction of the clock, and arm-tie 11 is pressed in the crank upper end, make it to drive upper connecting rod 8, stop 7 moves down together, stop 7 disengages with horizontal bolt 6, and behind the descending certain distance of upper connecting rod, straight pin 20 ejects and makes stop 7 location; Again key is rotated by clockwise direction shown in Figure 1, shift fork is with upwards pulling of lower pulling plate 15, lower pulling plate drives lower link 16, stop 18 and moves on together, stop 18 disengages with horizontal bolt 3, this moment is by the handle 29 that clockwise rotates shown in Figure 1, sprocket wheel 2 is moved to the left with changeing and driving chain 28, crosses crack between a door and its frame 30 and surmount the position of rocking bar 26 lower ends until reset baffle block 31, door gets final product complete opening.

Need at closing time, handle 29 is pressed counter clockwise direction shown in Figure 1 rotate, the chain right lateral, when reset baffle block 31 brushed up against rocking bar 26 lower ends, rocking bar rotated by counter clockwise direction, and promotion bent axle 25 moves in the direction of the clock.Because of rod member 24 are rigid connectors of bent axle 25 and crank 23, admittedly impel crank 23 to rotate counterclockwise, and it is up to promote push rod 22, makes the stop 21 of conical nose insert in the groove of straight pins 20 and forces the straight pin right lateral, has opened the up passage of last arm-tie 11, under the spring force effect, last arm-tie 11, upper connecting rod 8, stop 7 are up in the lump, and stop 7 contacts with horizontal bolt 6, along with the chain right lateral to the end rapids, stop 7 snaps in the lock hole of reserving on the horizontal bolt 6, and the top of lock is by locked.Also just in time be entrapped in the lock hole of reserving on the horizontal bolt with the stop 18 that horizontal bolt 3 surfaces contact this moment always, the bottom is simultaneously locked.

As long as pull bar, pulling plate structure changed a little can produce two door locks more than the horizontal bolt, make door lock more strong.

Claims (1)

1, a kind of how horizontal bolt door lock has column, horizontal bolt, lock core, it is characterized in that horizontal bolt (3) fixedlys connected with montant (4), montant (4) and horizontal bolt (6) pin joint; Lock core (12) is fixedlyed connected with shift fork (13); The shift fork both sides have last arm-tie (11) and lower pulling plate (15) respectively, and there is stop (7) last arm-tie upper end, and there is stop (18) the lower pulling plate lower end, and last arm-tie top also has removable pin (20), and removable pin can be slidingly connected with the linkage of closing the door.
