Abstract

The utility model relates to a drawer locking structure, which comprises a lock head, a poke rod, a fixed seat, a sliding block, a lock latch, a rotary piece, an elastic element and a fastening device. A clutch plate is sheathed on the rotary piece of the lock latch of the fastening device, and a convex column is renewedly arranged on the clutch plate. Both ends of the elastic element are fixedly arranged on the clutch plate and the rotary piece of the lock latch to be limited in a fixed angle to cause the drawer which is not closed to be pushed to be closed after the fastening device is locked to keep a locking state to prevent a lock catch from being damaged because of lapse of attention.

Description

The Drawer locking structure

A kind of Drawer locking structure can be with drawer playback of not shutting and the structure that locks automatically after finger is locked drawer especially.

This Drawer locking structure belongs to building class lock, key and door and window part field.

Existing various cabinet has runner mostly, often cause crank to be toppled over meeting accident injury with drawer because of opening one simultaneously, design safety buckle structure for this reason, but prior art can only be opened a drawer, (Fig. 1) be existing Drawer locking structural upright exploded view, (Fig. 2) be the stereo appearance figure of lock bolt blade, because this structure can only be opened a drawer by single, though reached the purpose of avoiding cupboard to topple over, but rotate synchronously if tapered end is rotated counterclockwise and drives poke rod with key, slide block is moved to the left, make the edge promotion projection of slide block below through hole make the lock bolt blade be rotated counterclockwise the recurrence locked position of coupler, if open a drawer this moment then can't not shut, must open the lock with the key, bring unnecessary trouble, easily cause lock bolt hook sheet to damage when still closing drawer under the situation of having locked because of bump lock bolt blade if the user forgets, the user often feels puzzlement, and the utmost point is waited to improve for this reason.

The purpose of this utility model provides a kind of Drawer locking structure, and this buckling device still can directly be broken the drawer of not shutting as yet after tapered end is locked into shutting, and keeps locking shape, needn't open the lock with the key again.

The purpose of this utility model can reach by following measure: this buckling device comprises: a lock bolt blade, it is a long strip-board shape, which is provided with several through holes, set firmly a central shaft in lock bolt blade one side, two distal process of central shaft are for outside the lock bolt blade, and lock bolt blade opposite side top is provided with through hole; Two ends are respectively equipped with a projection and a through hole before and after one side of one clutch plate, are provided with a decurved jacking block thereon between between projection and through hole, and a side is established a through hole thereon in addition; Two ends of one flexible member are individually fixed in the through hole of lock bolt blade and the through hole on the clutch plate; The purpose of this utility model also can realize by following measure: the flexible member that uses in the buckling device is an extension spring.

The utility model has the advantages that: have simple structure and the advantage easily installed and used, the lock that can not only bales catch closes has simultaneously and avoids forgetting because of user's inadvertent and still close the advantage that drawer causes the buckle structure damage under the situation of having locked.

The explanation of accompanying drawing drawing:

Fig. 1 is the three-dimensional exploded view of prior art Drawer locking structure

Fig. 2 is the stereo appearance figure of prior art lock bolt blade

Fig. 3 is a three-dimensional exploded view of the present utility model

Fig. 4 is the three-dimensional exploded view of buckling device of the present utility model

Fig. 5 is the utility model back action schematic diagram of buckling device when drawer pushes of locking

Fig. 6 is the utility model back action schematic diagram of buckling device after drawer pushes of locking

Now contrasting accompanying drawing is described in detail as follows the utility model:

Improvement structure (Fig. 3 of a kind of Drawer locking of the utility model, Fig. 4), comprise: a tapered end 1, the core of this tapered end 1 tail end is provided with a groove 2, fix an end of a poke rod 3 in the groove 2, the other end of poke rod 3 then passes a slide block 6 that fixedly can be free to slide on the holder 4 of the inboard end face tail end of cabinet to put objects, this slide block 6 is a Contraband shape, two top boards are provided with through hole 7 about slide block 6 one sides, on side plate, be respectively equipped with two through

holes

8,9, one of them through hole 8 passes drive for poke rod 3 tail ends, and another through hole 9 passes for reed 10 tail ends that are fixed in slide block side plate inboard; Two ends of one flexible member 11 are individually fixed on the projection 24 on clutch plate 23 tops in upper end holder 4 and the buckling device 18; One lock bolt hook sheet 12 is a tabular, and tail end has the groove 13 of a bending, is fixed on the drawer 17; One buckling device 18 comprises: a lock bolt blade 19 is a long strip-board shape, on it and be provided with several through holes 20, establish a central shaft 21 in a side of lock bolt blade 19, two distal process that make central shaft 21 are provided with a through hole 22 for outside the lock bolt blade 19 in lock bolt blade 19 opposite side tops; One side front and back end of one clutch plate 23 is respectively equipped with a projection 24 and a through hole 25, and on clutch plate 23, be provided with a jacking block 26 that bends downwards between projection 24 and 25 of through holes, opposite side on clutch plate 23 is provided with a through hole 27, two ends of one flexible member 28 are individually fixed in the through hole 22 of lock bolt blade 23 and the through hole 27 on the clutch plate 23, with this two through hole 22 that furthers, 27 distance is withstood lock bolt blade 19 up to the jacking block 26 of clutch plate 23 makes the two keep certain angle, in addition, borrow the strength of flexible member 28, make lock bolt blade 19 move and rotate with projection 24, simultaneously the through hole on the clutch plate 23 25 is inserted in central shaft 21 tops of lock bolt blade 19, two ends of central shaft 21 is penetrated respectively be fixedly arranged in the cabinet to put objects up and down in the through hole 5 of two ends holder 4 again; When rotating in a counter-clockwise direction, tapered end 1 of the present utility model locks, driving poke rod 3 rotates synchronously, make the edge of slide block 6 below through holes 7 promote projection 24 on the clutch plate 23, make the through hole on the lock bolt blade 19 20 in the buckling device 18 snap in 14 one-tenth blockings of grab of lock bolt hook sheet 12, at this moment if the drawer of not shutting 17 is arranged, as long as drawer is pushed inward, just can lock bolt blade 19 be pushed open and rotate an angle (Fig. 5 in a clockwise direction by the lock right tilted surface 16 of latch dog sheet 12 front ends of drawer 17, Fig. 6), but clutch plate 23 and slide block 6 are motionless, when treating that drawer 17 is pushed into the location, the pulling force that lock bolt blade 19 is just provided by flexible member 28, get back to the position of original locking, make all drawers all reach locking state.The utility model is not limit the foregoing description, also can change slightly.The utility model is simple in structure, is easy to install and use, and the lock that can bales catch closes has the user of avoiding simultaneously and causes the buckle structure damage because of inadvertent.
