Abstract

The utility model relates to a multi-bolt linked door lock which is a mechanical door lock. The utility model comprises a lock shell, a lock head, bolts, a key, etc. The utility model is characterized in that one lock head and a link gear drive a plurality of bolts to move, and the utility model comprises a pulling and poking part (1) on the lock head (17) and the link gear; the link gear comprises a link block (2), short connecting links (3), a pipe joint (5), and long connecting links (4); the pulling and poking part (1) on the lock body (17) is fixed inside a large lock shell (6); when the pulling and poking part rotates, the pulling and poking part is contacted with a large tongue plate (7), and the large lock shell (8) is fixed on the large tongue plate; three slide grooves are arranged on the link block (2), and one tilted slide groove of the slide grooves is movably matched with a circular male pin (11) on the large tongue plate (7); both ends of the link block (2) are connected with the long connecting links (4) through the short connecting links (3) and the pipe joint (5) respectively, and the upper short connecting link and the lower short connecting link are respectively connected with oscillating blocks (16) and the bolts (12), which are inside the upper lock shell (14) and the lower lock shell (13).

Description

Many tongues linked door lock

Many tongues linked door lock is a kind of mechanical door lock, and it is made up of parts such as lock housing, tapered end, dead bolt, keys.

Existing machinery door lock type is a lot, and they have a common characteristic, and every lock has only a position with dead bolt door and doorframe to be locked exactly.In case the door of this position is destroyed, just can open the door.

The firmness that combines between reinforced door and doorframe increases its intensity and rigidity, and don't need many locks be installed at same door, the purpose of Here it is many tongues of the utility model linked door lock.

The scheme of many tongues linked door lock adopts a tapered end to drive a plurality of dead bolt interlocks of several diverse locations, even dead bolt is in out or locking state simultaneously, its architectural feature is that tapered end and linkage structure drive a plurality of dead bolts.

Many tongues linked door lock is simple in structure, transmission is convenient, and door and doorframe bond strength increase than common flapper lock and many times.Firmness and rigidity increase and improve along with locked position, and anti-riot ability is strong, safe and reliable.

Now illustrate many tongues linked door lock scheme with an embodiment.

Fig. 1 is the assembling drawing of many tongues linked door lock;

Fig. 2 is the linkage structure figure of many tongues linked door lock.

This routine many tongues linked door lock has nine dead bolts to be divided into three groups in three locational lock housings; Tapered end, stir link gear.

One of this routine design feature is: on the tapered end (17) pull out peach (1) (Fig. 1) and the interlock mechanism; Link gear has comprised interlock piece (2), short connecting rod (3), long connecting rod (4) and union (5).Tapered end (17) and on the peach (1) of pulling out be contained in the big lock housing (6), during rotation, pulling out peach (1) contacts with large tongue plate (7), large tongue plate has the oblique chute of garden pin (11) and interlock piece (2) movingly, interlock piece (2) (Fig. 2) has three chutes, two chutes of one of them oblique chute and other become 30-60 degree angle, miter angle preferably, and three chutes all can slide in the pin of garden.The interlock piece is connected with short connecting rod (3) and long connecting rod (4) by union (5), and the length of long connecting rod (4) depends on the needs, and weak point connecting rod and last (14), the interior swinging block (16) of following (13) lock housing are connected.

Two of characteristics are that dead bolt is divided into several groups, this example nine dead bolts are divided into three groups, one group of five tongue, all the other two groups each two tongues, they are installed in big dead bolt (6) respectively, go up in lock housing (14) and the following lock housing (13), in the big lock housing four big dead bolts (8) and a little dead bolt (9) are arranged, four big tongues of garden column type are fixed on the large tongue plate (7), uvula is installed in (10) on the little hyoplastron, the middle dead bolt (12) that two garden column types are respectively arranged in the upper and lower lock housing, middle dead bolt is fixed on upper and lower, the middle hyoplastron (15), and middle hyoplastron cooperates with swinging block (16) upper hopper chute is movable.

The process of unblanking is, pull out peach (1) with key turns tapered end (17) drive, stir large tongue plate (7) toward moving right, the interlock piece (2) that large tongue plate drives on the link gear up moves, make upper and lower middle dead bolt toward moving to right by length connecting rod and swinging block (16), so just can open door, the counter-rotation tapered end can be locked when locking a door.

Many tongues of this example linked door lock is simple in structure, intensity is high, solid and reliable, use Convenient.

Claims

1, a kind of many tongues linked door lock is made up of lock housing, tapered end, dead bolt, key etc., it is characterized in that driving a plurality of dead bolts motions with a tapered end and link gear, and structure has last the dialling of tapered end (17) to choose (1) and link gear; Link gear comprises interlock piece (2), lacks connecting rod (3), union (5), long connecting rod (4), and last group of tapered end (17) is chosen (1) and is fixed in the big lock housing (6), contacts with large tongue plate (7) during rotation, is fixed with big dead bolt (8) on the large tongue plate; On the interlock piece (2) three chutes are arranged, one of them oblique chute and large tongue plate (7) are gone up garden pin (11) movingly, interlock piece (2) two ends are connected with long connecting rod (4) by short connecting rod (3) union (5) respectively, upper and lower short connecting rod is respectively with last (14), down the swinging block (16) in (13) lock housing is connected with middle dead bolt (12), so rotational lock head (17) drives and dials peach (1) the interior dead bolt of the upper and lower lock housing of big lock housing is moved.

2, many tongues linked door lock according to claim 1 is characterized in that described large tongue plate (7) installation four big dead bolts of garden column type (8), and dead bolt (12) in two garden column types respectively is housed on the hyoplastron in upper and lower.

3, according to claim 1,2 described many tongues linked door locks, take advantage of and be characterised in that the last oblique chute of described interlock piece (2) becomes 30-60 degree angle, preferably miter angles with other two chutes.
