The utility model satisfies the habit of most users and achieves the function of automatically locking the door at the same time as closing the door.

Description

The automatic mechanism for locking up of lockset

Technical field

The utility model relates to a kind of structure of lockset, more specifically says so and is applicable to standard machinery lock and electromechanical lock, in the structure of locking by the motion actuated main tongue of oblique dead bolt at closing time.

Background technology

The mode that existing theft-preventing mechanical lock and bank's door motor tool are locked lock is key or realizes that by the carrying handle hand main dead bolt locks, and operates cumbersomely, and particularly bank is anti-trails the electromechanical lock that linkage door is used, and has caused a lot of inconvenience to the user of service.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of automatic mechanism for locking up of lockset being provided, for meeting most of people's use habit, self-locking function when realizing closing the door.

The technical solution of the utility model is as follows:

The automatic mechanism for locking up of lockset, include mounting box, be provided with main dead bolt, oblique dead bolt in the mounting box, the lower end of described main dead bolt, oblique dead bolt is filled up respectively and is put main latch bolt spring, oblique latch bolt spring, tiltedly elasticity is hinged with turning block on the dead bolt, be provided with main tongue card between the sidewall of main dead bolt and the inside wall of mounting box, an end of main tongue card and the sidewall buckle of main dead bolt overlap joint are connected with main tongue card spring between the inside wall of the other end and mounting box; Be movably hinged with main dead bolt shifting block on the main dead bolt, the other end of main dead bolt shifting block and main tongue card are hinged, be hinged with the shifting block of locking on the sidewall of main tongue card, lock and have breach on the shifting block, engaging has the finger that is fixed on the main dead bolt in the breach, and the end face inclined-plane that is connected with unidirectional sliding-tongue and the shifting block of locking on the turning block is slidingly matched.

Also be rotatablely equipped with the handle shifting block in the described mounting box, the handle shifting block has the shifting block contact, and the shifting block contact extends and press on the lower end of oblique dead bolt.

The utility model compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model meets most of people's use habit, when closing the door, need not any additional people action and finishes and automatically lock.

2, the utility model is widely used in standard machinery lock and electromechanical lock.

3, simple in structure, the reliable in action of the utility model.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the oblique dead bolt of the present utility model initial equilibrium state schematic diagram that inwardly slides.

Fig. 3 is the oblique dead bolt of the present utility model last current state schematic diagram that inwardly slides.

Fig. 4 is the oblique dead bolt of the utility model view that skids off, automatically locks.

Lock shifting block, 4 lock fork pulling blocks, 5 bearing pins, 6 main tongue cards, 7 handle pulling blocks, 8 turning blocks, 9 clutches, 10 unidirectional sliding-tongue return springs, 11 sidepiece bayonet sockets, 12 main latch bolt springs, 15 main dead bolt pulling blocks, 21 oblique latch bolt springs, 31, fork, 61 fingers, 62 buckles, 63, main tongue card spring, 71, pulling block contact, 81 ingot pins, 82 unidirectional sliding-tongues, 83 separation heads of 1 main tongue, 2 oblique dead bolts, 3 wherein.

The specific embodiment:

Referring to accompanying drawing, tiltedly on the dead bolt (2) turning block (8) is being set, described turning block (8) is a rotating fulcrum with the ingot pin (81) that is arranged on the oblique dead bolt (2), the sidepiece of turning block (8) is unidirectional sliding-tongue (82), unidirectional what be slidingly matched is the rotating shifting block of locking (3) with described unidirectional sliding-tongue (82), the described shifting block of locking (3) is equipped with its shift fork (31) and finger (61), described finger (61) connects firmly on main tongue card (6), the outside portion of main tongue card (6) is and the buckle (62) of the corresponding setting of sidepiece bayonet socket (11) of main tongue (1) that the dial-out position of finger (61) is corresponding to the disengaging configuration of its buckle (62) with main tongue sidepiece bayonet socket (11).

In concrete the enforcement, the afterbody that oblique dead bolt 2 need be set respectively on each position is provided with oblique latch bolt spring 21, afterbody at main tongue 1 is provided with main tongue spring 12, in the outside portion of main tongue card 6 pintle hook lock spring 63 is set, the reliable in action at each position that assurance is set of each spring mechanism.

At closing time, tiltedly dead bolt 2 is to the afterbody motion, and 8 motions of band turning block separate with the shifting block 3 of locking, and break away from the bottom of the shifting block 3 of locking until unidirectional sliding-tongue 82; Immediately, turning block 8 resets under the effect of unidirectional sliding-tongue return spring, its unidirectional sliding-tongue 82 is in the bottom of the shifting block 3 of locking, tiltedly latch bolt spring 21 resets under the effect of oblique latch bolt spring 21 elastic forces, and promptly tiltedly dead bolt 2 slips in the oblique dead bolt hole, and the shifting block 3 of locking turns over counterclockwise around bearing pin 5, driving main tongue card 6 moves, thereby sidepiece bayonet socket 11 breaks away from buckle 62, discharges main dead bolt 1, finishes once self-locking process.

When main dead bolt 1 was regained, clutch 9 drove handle pulling blocks 7 and touches the main dead bolt of main dead bolt pulling block 15 motions and regain, and main tongue card 6 combines with sidepiece bayonet socket 11 on the main dead bolt 1 at the buckle 62 of taking advantage of a situation on the main tongue card 6 that resets under the spring action of main tongue card.Thereby in this simultaneously when handle pulling block 7 rotates 83 on the pulling block contact 71 on the handle pulling block 7 and the turning block 8 separate the head contact and realize that the unidirectional sliding-tongues 82 on the turning block 8 separate with the shifting block 3 of locking, and finish release.
