Abstract

The utility model discloses an opening device for an emergency lock of a safe box, which comprises a lock tongue sliding plate and a solenoid valve, wherein the solenoid valve locks the lock tongue sliding plate by a valve core; the device organically combines the electronic coded lock and the mechanical coded lock, and when the electronic coded lock cannot be opened due to various reasons, the safe can be opened by using the mechanical coded lock.

Description

The strongbox lock opening device of meeting an urgent need

Technical field

The utility model relates to the emergent lock opening device of a kind of strongbox.

Background technology

At present, the strongbox coded lock generally is divided into mechanical code lock, electronic password lock and electromechanical coded lock three major types.Mechanical code lock history is remote, is characterized in: use simple, safe and reliable, cheap.Its shortcoming is: the password number is insufficient, can't change in case make the password that finishes, and in addition, must carry a key, and tangible key provides the possibility of duplicating.Along with the development of people to requirements at the higher level on the theftproof lock performance and digitizing technique, a kind of novel electronic password lock by microprocessor control had obtained being extensive use of in recent years, be characterized in: need not key, utilize electronic touch formula button input password, open easy and convenient, the password number is numerous, and be easy to change password, but shortcoming also is conspicuous, such as problems such as the antivibration problem of the reliability and stability problem of electronic devices and components, electronic circuit board, battery lifes, all cause electronic lock to open easily.

Summary of the invention

The purpose of this utility model is: a kind of strongbox lock opening device of meeting an urgent need is provided, this device organically combines electronic password lock and mechanical code lock, when electronic password lock can't be opened for various reasons, can open this strongbox equally with mechanical code lock.

The technical solution of the utility model is: a kind of strongbox lock opening device of meeting an urgent need, comprise the dead bolt slide plate, with the electromagnetic valve of spool locking dead bolt slide plate, the described emergent mechanical code lock that is fixed with combination disk control of locking, mechanical cipher is locked and is provided with turning handle, be fixed with shift fork on the turning handle, shift fork can be stirred spool.

The further technical scheme of the utility model is: a kind of strongbox lock opening device of meeting an urgent need, comprise the dead bolt slide plate, with the electromagnetic valve of spool locking dead bolt slide plate, the described emergent mechanical code lock that is fixed with combination disk control of locking, mechanical cipher is locked and is provided with turning handle, be fixed with shift fork on the turning handle, shift fork can be stirred spool; The top of described dead bolt slide plate is provided with slotted hole, the lower edge is fixed with the right angle baffle plate, and the right-hand member of lock pin insertion slotted hole, spool backstop limit the move left and right of dead bolt slide plate in the right side of right angle baffle plate during locking.

The utility model has the advantages that:

1. the utility model has kept the advantage of electronic password lock, need not tangible key, the security reliability height, and password quantity is big and can change arbitrarily.

2. the utility model has in fact just become one mechanical code lock when electronic password lock can't be opened, and the user can come the opening safety case by mechanical code lock.

Description of drawings

The utility model will be further described below in conjunction with drawings and Examples:

Front view when Fig. 1 locks for the utility model;

Vertical view when Fig. 2 locks for the utility model;

Front view when Fig. 3 opens for the utility model;

Vertical view when Fig. 4 opens for the utility model.

Wherein: 1 dead bolt slide plate; 2 spools; 3 electromagnetic valves; 4 mechanical code locks; 5 turning handles; 6 shift forks; 7 slotted holes; 8 right angle baffle plates; 9 lock pins; 10 combination disk.

The specific embodiment

Embodiment: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of strongbox lock opening device of meeting an urgent need, comprise dead bolt slide plate (1), electromagnetic valve (3) with spool (2) locking dead bolt slide plate (1), the top of dead bolt slide plate (1) is provided with slotted hole (7), the lower edge is fixed with right angle baffle plate (8), lock pin during locking (9) inserts the right-hand member of slotted hole (7), spool (2) backstop is in the right side of right angle baffle plate (8), the move left and right of restriction dead bolt slide plate (1), described emergent locking is fixed with mechanical code lock (4), mechanical code lock (4) is provided with the turning handle (5) with combination disk (10) control, be fixed with shift fork (6) on the turning handle (5), shift fork (6) can be stirred spool (2).

When electronic password lock breaks down and normally during the opening safety case, stir the combination disk (10) of mechanical code lock (4), predefined password number is aimed at the lock center, turning handle (5), drive shift fork (6) spool (2) is pressed down, mobile again dead bolt slide plate (1) is the opening safety case smoothly.

Claims

1. the emergent lock opening device of a strongbox, comprise dead bolt slide plate (1), use spool (2) to lock the electromagnetic valve (3) of dead bolt slide plate (1), it is characterized in that: the described emergent mechanical code lock (4) that is fixed with combination disk (10) control of locking, mechanical code lock (4) is provided with turning handle (5), be fixed with shift fork (6) on the turning handle (5), shift fork (6) can be stirred spool (2).

2. the strongbox according to claim 1 lock opening device of meeting an urgent need, it is characterized in that: the top of described dead bolt slide plate (1) is provided with slotted hole (7), the lower edge is fixed with right angle baffle plate (8), the right-hand member of lock pin during locking (9) insertion slotted hole (7), spool (2) backstop limit the move left and right of dead bolt slide plate (1) in the right side of right angle baffle plate (8).
