Abstract

The utility model discloses a novel locking anti-theft device which is formed by that the back end of the square tongue of an automatic lock with two tongues is fixedly connected with an omnibearing locking mechanism with a plurality of tongues. The mechanism is mainly composed of a crescent fork with two heads and a triaster fork with three heads. The crescent fork with two heads and the triaster fork with three heads can respectively move in a rotatory way. The crescent fork and one end of the triaster fork are movably connected with the square tongue of the automatic lock with two tongues, and other ends are sheathed in a hole as a locking tongue bolt rod. When the square tongue of the automatic lock with two tongues is locked, the crescent fork and the triaster fork of the locking mechanism with a plurality of tongues are driven synchronously to move in a rotatory way. Meanwhile, the tongue bolt rod is driven to do rectilinear movement by the rotation of the crescent fork and the triaster fork to obtain the goal of omnibearing locking from top to bottom as well as from left to right.

Description

Locking device with several bolts

The utility model relates to the antitheft retaining mechanism that uses in people's daily life, the omnibearing locking device of a kind of specifically several bolts.

General automatic locking is installed on timber, iron gate or the strongbox, implements unidirectional locking, and its anti-theft capability is very poor, often must by means of other install attached help carry out antitheft.Two tongue automatic lockings or all kinds of theftproof locks are also only implemented antitheft task in direction locking back, because the restriction of its function and effect, often stolen phenomenon remains very serious.

It is reported and utilized the locking while at lock such as gear, pull bar and push rod by a kind of strongbox, locked to same emersion one tongue bar at the upper and lower of chamber door.And be used for implementing on the iron gate of door, particularly house the omnibearing retaining mechanism in upper and lower, left and right, have not yet to see.

The purpose of this utility model is on the basis of two tongue automatic lockings, designs a kind of retaining mechanism of several bolts in addition, makes two tongue automatic lockings drive this mechanism in locking and accomplishes the omnibearing locking in upper and lower, left and right, makes it reach effective antitheft effect.

The purpose of this utility model is achieved in that in the square tongue rear end of two tongue automatic lockings and connects a push pedal that is synchronized with the movement with two tongue automatic locking side tongues, push pedal is installed in the middle of the special fixed head housing, the crescent moon fork of double end and three Samsung fork are installed in the fixed head housing, and they can both rotate around its central axis respectively.One end of crescent moon fork is connected with push pedal by steady pin is spacing, in the slot of other end insertion as the tongue tightening latch of locking; One end of Samsung fork is connected with push pedal by steady pin is spacing, and other two ends also insert in the tongue tightening latch slot of locking with the conduct that cooperates respectively.When two tongue automatic lockings are locked, promptly drag the direction motion of push pedal to locking, push pedal also drives the direction motion of crescent moon fork and Samsung fork to square tongue locking simultaneously like this, because crescent moon fork and Samsung fork all are to rotate around its central axis respectively, so when their the limited rotation of an end, the other end so promptly promotes the tongue tightening latch that inserts respectively also along with rotation, outwards emersion, therefore the opposite direction of two tongue automatic locking sides tongues locking and on to down to implementing locking.

Linear running when the utility model utilizes the square tongue locking of two tongue automatic lockings, the crescent moon fork and the Samsung fork that drive double end and three rotate, and make the tongue tightening latch be converted to rectilinear motion again, thereby reach the omnibearing locking purpose in upper and lower, left and right.This mechanism structure is simple, and reliable lock is because the locking in four orientation is pried open the state that all can't open locking from that direction, so can play antitheft effect effectively.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is comprehensive several bolts retaining mechanism, and it is by special positioning and fixing plate housing (1); Be installed in the crescent moon fork (2) in the fixed head housing (1); The fixing crescent moon fork mandrel (3) at crescent moon fork (2) center; The lower end slot is inserted in the last tongue tightening latch (4) of crescent moon fork (2) head; Be installed in the Samsung fork (5) in the fixed head housing (1); Fixedly the Samsung at Samsung fork (5) center is pitched mandrel (6); The upper end oblong aperture is inserted in the sublingua tightening latch (7) on Samsung fork (5) head; One side slot is inserted in the side tongue tightening latch (8) on Samsung fork (5) other end and fixedly the steady pin (9) and the push pedal component such as (10) of crescent moon fork (2) one terminations constitute.Be processed with several holes and groove on the positioning and fixing plate housing (1), do stationary fit or wait movingly with above-mentioned part in addition respectively.

Fig. 2 is the schematic diagram that comprehensive several bolts retaining mechanism is connected with general two tongue automatic lockings, promptly in the rear end of two tongue automatic locking side tongues fixedly connected and prolong the emersion certain-length block length side's plate (11); Rectangular plate (11) is fixedlyed connected with push pedal (10) among Fig. 1, and rectangular plate of the side's of making tongue (11) and push pedal (10) three fuse and move on same straight line like this.

The utility model is to realize its comprehensive locking task like this, when key inserts two tongue automatic lockings and locks, square tongue emersion in company with two tongue automatic lockings, rectangular plate (11) and push pedal (10) are also moved to the direction of square tongue emersion simultaneously, because the displacement of push pedal (10), crescent moon fork (2) and Samsung that the termination is fixed in the push pedal (10) are pitched (5) also in company with displacement, because crescent moon fork (2) and Samsung fork (5) all is to rotate for the center around its mandrel (3) and (6) respectively, the displacement space when they were fixed on push pedal (10) upward the place of steady pin (9) all had the Yao Yuan hole as rotation respectively the while.So moving along with push pedal (10), crescent moon fork (2) and Samsung fork (5) promptly begin to rotate around its mandrel, their jaw has promptly driven cover last tongue tightening latch (4) thereon, sublingua tightening latch (7), side tongue tightening latch (8) makes progress, reaches the side emersion respectively downwards, implement the locking task, its emersion effective length equates with the distance of two tongue automatic locking sides tongue emersion.So promptly finished the omnibearing locking task in upper and lower, left and right, Fig. 3 is a schematic diagram of finishing the locking task.Open retaining mechanism, as long as key is turned round back original position, each tongue tightening latch of two tongue automatic lockings and comprehensive retaining mechanism is also got back to original position.

The utility model is simple in structure, and reliable in action is easy to use, is applicable to door, cabinet door, the chamber door of various material, is a kind of effective desirable anti-theft device.
