Description
Technical field
This utility model relates to condom technical field, particularly relates to a kind of Safe lock.
Background technology
Condom is a kind of special container, is broadly divided into salamander and thief-resistant safe, antimagnetic condom, antimagnetic condom etc. of preventing fires according to its function.Condom can be divided into again mechanical type condom, electronic safe, and machine insurance case Performance comparision is reliable, but is on inconvenience, and electronic safe is easy to use.The carrying of some valuables, carrying, need insurance, the most present condom is gradually to small-sized development, it is simple to carry；But lock core on common condom, buckle structure volume are relatively big, mechanism is complicated, if being directly used in small-sized condom can take the space of condom, if parts are scaled, then processing and manufacturing difficulty, and small-sized condom is owing to being easy to carry, spacing instability after some snap close and lock core connection, can be by falling, beat condom and opening.The lockable mechanism of the most common small-sized condom is excessively simple, lack auto-lock function, and poor safety performance is easily opened.
Utility model content
This utility model is in order to solve the problems referred to above of the prior art, it is provided that a kind of Stability Analysis of Structures, take up room little, easy to use, safe Safe lock, is especially suitable on small-sized condom using.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of Safe lock, in the control box being arranged in condom, including base, the motor that is located on base, described base is provided with two pieces of parallel connecting plates, being provided with dead bolt seat between connecting plate, be slidably connected between described dead bolt seat and connecting plate, described dead bolt seat is provided with the dead bolt of evagination；It is additionally provided with torsion spring seat on described base, torsion spring seat is provided with torsion axis, torsion axis is provided with torsion spring, the two ends of described torsion spring extend and form torsion spring arm, described torsion spring arm is connected with dead bolt seat, the middle part of described torsion spring extends and forms reset arm, the outer end of reset arm contacts with dead bolt medial surface and exceeds dead bolt top, described torsion axis is provided with torsion spring plectrum assembly, the axle head of described motor is provided with cam, the outside controlling box is provided with coded lock component, is provided with wiring board, power supply in controlling box, and described coded lock component, motor, power supply are all connected with wiring board.Arranging snap close on safe door, when chamber door covers, dead bolt stretches into locking in snap close, and reset arm is pressed in snap close end；When needing to open chamber door, motor is opened by coded lock component, driven by motor cam promotes torsion spring plectrum assembly to rotate, torsion spring plectrum assembly drives torsion spring arm to rotate, torsion spring arm promotes dead bolt seat to move and snap close disengaging, latch in automatically be open under the effect of reset arm, chamber door automatically opens up, thus unlock；Whole mechanism uses coded lock to be combined with mechanical lock, and compact conformation, volume are little, easy to use, mechanism stable.
As preferably, described torsion spring plectrum assembly includes torsion spring limit base, is located at the plectrum of torsion spring limit base side, and described torsion spring limit base is rotationally connected with torsion axis, torsion spring limit base be respectively arranged at two ends with the spacing auricle of torsion spring arm being pressed on torsion spring arm.Cam driven plectrum rotates, and the spacing auricle of torsion spring arm on torsion spring limit base drives torsion spring arm to rotate.
As preferably, described connecting plate is provided with arcuate groove obliquely, the center of circle of arcuate groove and the centres of torsion spring, the both sides of described dead bolt seat are equipped with tilted slotted hole obliquely, the outer end of described torsion spring arm is bent to form positive stop hook, described positive stop hook is through stretching in arcuate groove after tilted slotted hole, and arcuate groove, tilted slotted hole constitute torsion spring arm self-locking limit mechanism.When torsion spring arm rotates under the driving of torsion spring plectrum assembly, the outer end of torsion spring arm moves to lower end from arcuate groove upper end, and torsion spring arm moves to upper end also from the lower end of tilted slotted hole simultaneously, drives dead bolt seat to move down, and snap close separates with dead bolt, opens chamber door；Owing to tilted slotted hole is contrary with the incline direction of arcuate groove, therefore the outer end of torsion spring arm no matter be positioned at which end of tilted slotted hole (arcuate groove) can self-locking limit, only from outside, the direction of rotation of torsion spring is applied active force and just can break self-locking, the circular motion of torsion spring arm outer end orders about dead bolt seat by the synergism of arcuate groove Yu tilted slotted hole and does linear motion locking, mechanism is simple, exquisite, stable, even if collision, falling and be also not result in that dead bolt separates with snap close.
As preferably, on described base in be positioned at the side of cam and be provided with limit switch.Limit switch can control the rotational angle of cam.
As preferably, described torsion spring plectrum assembly is provided with auxiliary plectrum, and described base is provided with lock core mounting seat, is provided with lock core in lock core mounting seat, described lock core is provided with the lock plectrum driving auxiliary plectrum to rotate, and described coded lock component is provided with the lockhole corresponding with lock core.When coded lock component fault or motor do not have electricity when, can rotate lock core at lockhole in inserting lock core by key, after the lock plectrum on lock core rotates, band dynamic auxiliary plectrum rotates, thus controls dead bolt and unlock.
As preferably, the outside that described coded lock component is positioned at lockhole is provided with concealed cover plate.Concealed cover plate can play covering, hidden, the effect of protection lock core.
Therefore, this utility model has the advantages that (1) overall structure is simple, compact, volume is little, it is simple to install；(2) when dead bolt is deviate from from snap close, the snap close arm that is reset is pushed open automatically, and chamber door automatically opens up；(3) there is auto-lock function, can prevent the inertia produced by actions such as colliding, fall from unlocking.
