Abstract
The utility model relates to a safety lock with an automatic locking device, which comprises a lock housing, two bolts arranged in the lock housing, a set bar penetrating through the housing body, and two shifting pins which is limited on the lock housing via pivots at the part adjacent to the central part and the side part; pipe fittings are embedded on the peripheries of the two bolts; one end of each shifting pin is fixed on the pipe fittings, and the other end can be close to or can be appressed to a convex post on an eccentric disc. The safety lock with an automatic locking device adopts an automatic locking device, so the operational procedure of the lock can be simplified; in addition, the utility model adopts a structure of the two bolts, so the safety of the utility model is high.
Description
The utility model relates to a kind of safety lock with automatic locking apparatus, especially is suitable for the mechanical lock that uses two keys to start.
Be used for the mechanical lock on the wing, usually have only one to be used for the steering assembly that specific keys just can make its rotation, this steering assembly is being controlled and is being arranged on its anterior eccentric disc, on eccentric disc, be provided with and radially pass latch rear groove projection, along with the rotation of steering assembly can be directed to another lock-bit from a lock-bit with latch, the prerequisite that steering assembly rotates is that when pin was pressed into correct position, steering assembly could rotate after must making its inner peg and the tooth at key edge being meshed.So, the lock of this kind structure open or locking relevant with the position at pin place, this can use an elongated member for the veteran, the pin in the steering assembly is pulled out the correct position that can make its rotation, and lock is opened.In addition, this kind lock can not be locked automatically, and must through specific keys insert and the rotation steering assembly after could lock, so this kind latching operation process complexity comparatively, to such an extent as to the phenomenon that neglects locking the door or lock other wing can occur.
Task of the present utility model provides a kind of safety lock with automatic locking apparatus, and this lock can prevent to open it with the device beyond the key very effectively, and can simplify the operation sequence of lock.
For finishing above-mentioned task, the utility model comprises a lock housing, and two latches are installed in this lock housing with keeping at a certain distance away, and the lock-bit of each latch is controlled by projection on the eccentric disc and the return spring that is arranged on its two ends respectively; With in the break-through housing and periphery be nested with the locking bolt of pipe fitting; And approach two that middle part and limit portion zone be limited on the lock housing by pivot respectively and pull pin, this end of pulling pin is fixed on the above-mentioned pipe fitting, and the other end can be close with the projection on the eccentric disc or subsides mutually.
Described locking bolt one end is provided with swing handle, and the other end is arranged to tapered taper shape.
Described pulling pin can be made of the rod member of bending, and its crooked position is provided with and makes the pivot of pulling pin and can rotate around it.
Described two latches can be provided with point-blank.
Described locking bolt or pipe fitting outer setting have an elastomeric element that makes it recover the origin-location.
Because the utility model adopts two steering assemblies that started by key on lock housing, even the veteran can not open it in little scope simultaneously again, so this kind lock insures very much; In addition, this lock adopts an automatic locking apparatus, and the operation sequence that it has simplified lock has further improved the safety of using this lock.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is a cross-sectional view of the present utility model;
Accompanying drawing 2 is locking bolt and outer tube schematic appearance among Fig. 1.
Referring to Fig. 1, it provides the inner overall structure of this lock.It comprises a lock housing 1 and is arranged on two latches 2 and 3 in this lock housing that latch 2 and 3 can be provided with point-blank.Latch 2 and 3 action are controlled by the projection 51 on return spring 4 that is arranged on its limit portion and the eccentric disc 5 respectively, when wanting latch 2 or 3 is in the lock state, as long as rotate with key insertion steering assembly and to predetermined direction, the projection 51 that can drive on the eccentric disc 5 breaks away from screens, two latches are stretched out and lock, this moment, latch 3 withstood on latch 2 afterbodys, want to make latch 2 returns, must make latch 3 returns simultaneously, promptly necessary two steering assemblies of counter-rotation simultaneously could be opened lock.For making projection 51 that the precalculated position can be arrived smoothly exactly, between projection 51 and latch, be provided with an extension spring 6.The above-mentioned steering assembly and the steering assembly of prior art are basic identical, so do not provide in the accompanying drawing 1.
Locking bolt 7 axially passes lock housing 1, and its outside is nested with pipe fitting 71, and has one to make its elastomeric element that can recover the origin-location 72 in this pipe fitting suitable position amount of establishing, and this elastomeric element can be made of the compression spring that an end has a fixed dam 73.
Can see also that from Fig. 1 two of being limited on the lock housing 1 by pivot 81 pull pin 8, this is pulled pin and can be made of the rod member of bending, and pivot 81 can be set in its crooked position, and can rotate in the fixed pan at its place.8 one ends of pulling pin are fixed on the pipe fitting 71, and the other end is arranged on and approaches above-mentioned projection 51 peripheries (when latch 2 and 3 during in open mode).
Referring to Fig. 2, locking bolt 7 one ends are provided with swing handle 74, and the other end is arranged to the taper shape that is tapered, and appropriate location extends outward a projection 75 in the middle of it.Pipe fitting 71 is being provided with axial slide 711 with projection 75 opposite positions, and this chute is provided with three grooves 712 that are used for fixing projection 75.When rotating swing handle 74 and making projection 75 be put in the middle groove 712, pipe fitting 71 can be with locking bolt 7 action, and when locking bolt 7 front ends were subjected to that radially resistance is mobile backward, pipe fitting 71 was also with its action, can make 8 the front end of pulling pin stir projection 51, make latch 2 and 3 arrive latched positions automatically.
