Abstract

The utility model provides a tridirectional door bolt linkage door lock device for a safe. On the foundation of a door lock which is only provided with a transverse bolt, an upper bolt and a lower bolt are added. The back ends of the three bolts are sheathed and connected to the fixed axle of a safe door through longitudinal slotted holes, and the fixed axle is respectively sheathed with the transverse slotted holes of the three bolts through three convex heads which are arranged at the front and the back of a turntable sheathed and connected to the fixed axle to cause the three bolts to generate linkage. The lock tongues of two locks arranged in the safe door are respectively connected with the steps of the transverse bolt and the lower bolt. As the three door bolts generate linkage to lock the safe door firmly, the prying prevention performance is improved effectively, and the utility model is suitable for various safes.

Description

Safety cabinet three-dimensional keeper linked door lock device

The utility model relates to the safe door locking device, particularly a kind of safety cabinet three-dimensional keeper linked door lock device.

As everyone knows, safety cabinet (claiming " folder ten thousand " again) is to be used to deposit in money, the cabinet of valuables and file.For safety, safety cabinet all are equipped with many tapered end, after these tapered ends must being opened during use, keeper disengaging cabinet is opened the cabinet door just can stir the handle of cabinet door.In the prior art, the keeper of safety cabinet often has only horizontal keeper, and does not upper and lowerly have, and therefore gives opportunity of thief, with crowbar the top of cabinet door or bottom is pried open money or valuables are stolen.This type of incident happens occasionally, and this existing just safety cabinet is short of part in design.

The purpose of this utility model is to overcome the deficiency of existing safety cabinet, provides a kind of cabinet door that is not easy to pry open, the good safety cabinet three-dimensional of safety keeper linked door lock device.

Fig. 1 is the front view of the utility model broken section.

Fig. 2 is along the sectional view of A-A line among Fig. 1.

Fig. 3 be among Fig. 2 B to partial sectional view.

Structure of the present utility model is such: such as Fig. 1～shown in Figure 3, and this door lock assembly bag Draw together the horizontal keeper (14) of cabinet door (1), tapered end (10), tapered end (12), handle (11) and interlock thereof, its feature Be to also have upper keeper (2) and lower keeper (8), horizontal keeper (14), upper keeper (2) and lower keeper (8) The rear end is socketed on the dead axle (5) of cabinet door (1) separately with its vertical slotted hole (4,20 and 17) On, laterally also be socketed a rotating disk (3) on the dead axle (5) between keeper (14) and the upper keeper (2), The positive upper off-centered plush copper of rotating disk (3) (7) is laterally oval with horizontal keeper (14) corresponding position Hole (6) socket, two off-centered plush coppers in its back side (18 and 22) respectively with lower keeper (8) and the horizontal slotted hole (19 and 21) of upper keeper (2) corresponding position socket-connect tapered end (10 With 12) dead bolt block respectively the step (9 and 13) of horizontal keeper (14) and lower keeper (8).

The purpose of this utility model can also realize by following measure: laterally the front end of keeper (14), last keeper (2) and following keeper (8) is preferably made fork configuration, to enlarge the join domain of keeper and cabinet, further improves the pick-proof performance of safety cabinet.

The utility model is work like this: in the time of need opening the cabinet door, earlier tapered end (10 and 12) is opened, allowed its dead bolt break away from the step (13 and 9) of horizontal keeper (14) and following keeper (8) respectively, remove the constraint of tapered end to them.Use hand pulling handle (11) then, the slotted hole of stirring on the horizontal keeper (14) by the plush copper (16) of its connecting rod (15) termination moves horizontal keeper (14) in cabinet door (1).The plush copper (7) that the slotted hole (6) of at this moment horizontal keeper (14) rear end just promotes on the rotating disk (3) rotates counterclockwise, make two plush coppers (18 and 22) of rotating disk (3) back also do to rotate in the same way, horizontal slotted hole (19 and 21) by socket with it moves keeper (8) and last keeper (2) simultaneously in cabinet door (1), three keepers (2,8 and 14) just break away from cabinet, remove the constraint of cabinet door (1), open with being about to door.When closing cabinet door (1), oppositely pulling handle (11) inserts in the keyhole of cabinet three keepers (2,8 and 14) simultaneously, with key tapered end (10 and 12) is locked, the overhanging respectively step (15 and 9) of horizontal keeper (14) and following keeper (8) being blocked of its dead bolt gets final product again.

From structure of the present utility model and mode of occupation as can be known, because the three-dimensional keeper is all locked three directions of cabinet door (1) except that the hinge place simultaneously, the thief just has no way of doing it and with crowbar door is pried open, and has solved the deficiency of prior art effectively, has improved the security performance of safety cabinet.In addition,, do not change existing opening door operation because the action of three keepers link, uses very convenient, and relatively simple for structure, easy enforcement.

The utility model is applicable to various safety cabinets or similarly cabinet use.
