Abstract

A driver of electric lock bar, arranged in a lockset, comprises a motor, a spiral spring and a lock bar. The motor is composed of a power output shaft and a driving shaft equipped with a screwed section, wherein the spiral spring forms a screwed jointing section corresponding to the screwed section of the driving shaft, the lock bar comprises a plant rod connected and interlocked with the spiral spring. Freedom degree of rotation direction is limited by the inner structure of the lockset, thus rotation power output by the motor transforms rotating motion of the lock bar generated with the spiral spring to linear motion inside the lockset. The driver of electric lock bar can be not only easily modularized, but also easily mounted in various locksets, thereby simplifying structures and assembly of locksets.

50 driven members, 81 locking draw-in grooves

The specific embodiment

At first, see also Fig. 1, shown in Figure 2, the utility model is that to be arranged at lockset inner and include:

One motor 20, power output shaft is in conjunction with

driving shaft

22a or 22b with thread segment;

One

helical spring

30a or 30b, this driving

shaft

22a or 22b thread segment are formed with screwing section relatively; Wherein, first embodiment of helical spring 30a, the thread segment that makes inner segment and this driving shaft 22a not tool screws togather relation, in, outer section has the relation of screwing togather with the thread segment of this driving shaft 22a; Again, second embodiment of helical spring 30b, make inside and outside section with the thread segment of this driving shaft 22b not tool screw togather relation, the thread segment of stage casing and this driving shaft 22b has the relation of screwing togather;

One lock bolt 40 is formed with the inserting pole 41 that combines interlock with this

helical spring

30a or 30b, and rotation to degree of freedom be subjected to the restriction of lockset internal construction; Again, the aspect that combines of this inserting pole 41 and

helical spring

30a or 30b, be to be formed with axial profile groove 411 in this inserting pole 41, and the ending end of this

helical spring

30a or 30b is inserted in this axial profile groove 411, allow this inserting pole 41 and this

helical spring

30a or 30b accept rotary power synchronously, borrow in addition a latch 42 that is fixed in this inserting pole 41, cause this

helical spring

30a or 30b can't break away from this inserting pole 41.

Based on said structure, operating state of the present utility model, because of 40 rotations of this lock bolt to degree of freedom be subjected to the restriction of lockset internal construction, and when these motor 20 outputting rotary powers, be passed to the screwing section of this

helical spring

30a or 30b via the thread segment of this driving

shaft

22a or 22b, this

helical spring

30a or 30b are former should to be rotated thereupon, but lock bolt 40 because of this helical spring 30a or the combination of 30b outer end institute, rotation to degree of freedom be restricted, be transformed into rectilinear motion and will rotatablely move, that is changing the compressive state of this

helical spring

30a or 30b, 40 of this lock bolts produce displacement because of continuous action relation; Therefore, can utilize the lock-out state of the displacement change lockset of this lock bolt 40.

Yet, limit the lockset internal construction of these lock bolt 40 rotations to degree of freedom, can be as Fig. 3～shown in Figure 5, one annular driven member 50 is linked in an annular driving link 60, and these driving link 60 relative these lock bolts 40 are formed with axial draw-in groove 61, limit 40 rotations of this lock bolt to degree of freedom, and the axial draw-in groove 61 of these driven member 50 relative these driving links 60 is formed with axial linked slot 51 and the hoop groove 52 that dallies; So when these motor 20 outputting rotary powers, lock bolt 40 promptly can produce displacement in the axial draw-in groove 61 of this driving link 60; And when lock bolt 40 was positioned at the position of these driven member 50 formation hoop idle running grooves 52, driving link 60 was to drive driven members 50 rotations to unblank by lock bolt 40; When this lock bolt 40 was positioned at the position of the axial linked slot 51 of these driven member 50 formation, the driving link 60 of lockset can and then be unblanked by these lock bolt 40 drive driven members, 50 rotations in addition.

Moreover, limit the lockset internal construction of these lock bolt 40 rotations to degree of freedom, in addition can be as Fig. 6, shown in Figure 7, utilization is formed with the fixture 70 of axial draw-in groove 71, limit 40 rotations of this lock bolt to degree of freedom, and the tumbler 80 in order to present the lockset lock-out state, and the displacement movement of this lock bolt 40 locks draw-in groove 81 to being formed with relatively; So when these motor 20 outputting rotary powers, lock bolt 40 promptly can produce displacement in the axial draw-in groove 71 of this fixture 70; And work as the locking draw-in groove 81 that lock bolt 40 is positioned at this tumbler 80, tumbler 80 is can't rotate to unblank; Recess in addition the locking draw-in groove 81 of this tumbler 80 when this

lock bolt

40,80 of tumblers are rotatable and unblank.

But, application aspect of the present utility model is non-only to be that above stated specification is cited, still has multiple application aspect to enumerate one by one, because of non-be patent target of the present utility model, repeat no more.In addition, after the utility model also had a kind of outside abnormality to eliminate, lock bolt 40 was automatically replied entopic characteristic; For example, when lock bolt 40 is positioned at the position of these driven member 50 formation hoop idle running grooves 52,, driven member 50 rotates (normal condition should be to drive driven member 50 by driving link 60 to rotate) voluntarily but being subjected to unusual external force, and lock bolt 40 must be when the motor 20 direction displacements, 40 of lock bolts can be stuck in the hoop idle running groove 52 of this driven member 50, and outer section of

helical spring

30a or 30b then can be elongated; And after this driven member 50 unusual external force of rotating are eliminated in season, when allowing driven member 50 get back to normal position, lock bolt 40 can be by

helical spring

30a or 30b outside section pulling force of being accumulated, automatically revert to the normal position; Yet the aspect that the outside abnormality of this kind is taken place can have different aspects because of applied lockset classification is different, can't enumerate one by one, also repeats no more.

From the above mentioned, driving

shaft

22a or 22b that the utility model utilization has thread segment drive helical spring 30a or the 30b that is screwed, be incorporated into the lock bolt 40 that

helical spring

30a or 30b outer end and rotation are restricted to degree of freedom in the cooperation, rotatablely moving of

helical spring

30a or 30b promptly is transformed into the rectilinear motion that changes compressive state, and then make lock bolt 40 produce displacement, can utilize the lock-out state of the displacement change lockset of lock bolt 40 then; Wherein, the stage casing of this helical spring 30b is a screwing section, cooperates inner segment and outer section to be all the design that tool not screws togather relation, and the displaced position of this lock bolt 40 can be by the length control of screwing section; This helical spring 30a because of in, outer section is all the design that tool screws togather relation, can control the displaced position of this lock bolt 40 by the conduction time of motor 20; Therefore, motor 20 of the present utility model can drive lock bolt 40 with small electric power and change its position, utilizes battery that required electric power can be provided, and need not be connected to civil power, and structure is all simple with installation, and has the effect of simplifying lock structure and installation.
