Abstract

The utility model relates to a transmission device of a lock cylinder rotating mechanism. The transmission device of the lock cylinder rotating mechanism comprises a motor, a motor drive worm and a transmission sliding block, wherein the motor is the source of power; and the transmission sliding block is driven by a worm drive transmission component to move. The transmission device of the lock cylinder rotating mechanism is characterized in that the transmission component is an elastic folding component; and one end of the transmission component coordinates with the transmission sliding block to push the transmission block and the other end of the transmission component coordinates with the worm to convert rotation of the worm into linear movement. By adoption of the folding component, rotation of the worm is converted into linear movement, the space and the moving distance are saved, and a better transmission device is provided for a more delicate lock cylinder structure.

Description

Transmission device in the lock core rotating mechanism

Technical field

The utility model relates to door latch structure, relates in particular to the inner transmission device that drives the rotating shaft of drive block interlock lock core of door lock.

Background technology

The utility model relates to the dynamo-electric door lock that transforms, and so-called Mechanical & Electrical Transmission converts electric power control into mechanical movement exactly, finally drives the lock core rotating shaft and rotates, and opens or the locking lock core.Here related a kind of transmission device is exactly to be controlled by motor can select and lock core driving-chain wedging or the device that breaks away from.

In electromechanics transforms door lock, a turning cylinder that connects from front and back is arranged usually, this turning cylinder is with outside the driving block that is controlled by power system cooperates; Not with any parts generation interaction relation; Here so-called cooperation often is meant the fit system in many ribs axle and many ribs hole, and driving block is the parts that can select to cooperate or cut off driving-chain with whole driving-chain, so if constitute a complete driving-chain; Need let driving block and drive disk assembly afterwards keep the relation of wedging; Certainly when need not operate, driving block can break away from driving-chain again, breaks off driving-chain.

In some existing technology, once occurred being connected to driving block then through motor, and drove driving block and move, individual fulcrum was arranged in the middle of the spring of this fold-type with a kind of spring of fold-type; Utilize lever principle; Exchange the upper and lower displacement of opposite side for displacement before and after the side, but the defective of this technical scheme is that the exquisite size of door latch structure is little; To realize from the motorized motions to the machine power, transforming with the space and the displacement of minimum; This fold-type spring can not be optimized and utilizes the space, and the displacement that space that lever need occupy and lever can be practiced thrift is more, accomplishes that the door lock the inside relatively takes up room; So need find out a can from the electric power to the machine power, the conversion, being linear moving movement with the rotational motion variation.

Summary of the invention

The utility model has proposed the transmission device that a kind of size own is little, move province's distance to above situation.

The technical scheme of the utility model is: the transmission device in a kind of lock core rotating mechanism; Comprise motor, motor-driven worm screw, driven mobile driving block by the worm drive transmission component; It is characterized in that; Said transmission component is that one one end cooperates the promotion driving block with driving block, and the other end cooperates the rotation with worm screw to be converted into linearly moving rubber-like fold-type member with worm screw.

Said fold-type member is the parts of global formation, has a strong point at the position of fold-type member bending, and the said strong point is by a stent support, is exactly the other end that is moved forward and backward by drive along with worm screw rotation meeting that is stuck in the worm thread under the strong point.

Said fold-type member is divided into crimp and shelves bar parts, and the strong point of bending is arranged in the crimp, supported support of the strong point, and the position under the strong point is connected to move forward and backward the mode that drives the crimp rotation along with shelves bar parts with shelves bar parts.

The beneficial effect of the utility model is: through the fold-type member, the rotation of worm screw is converted into linear moving, and saves space and displacement, for exquisite more lock core structure provides better transmission device.

Description of drawings

Fig. 1 is the utility model structural representation.

Wherein: 1, driving block; 2, driving-chain base; 3, crimp; 4, shelves bar parts; 5, worm screw; 6, motor; 7, rack shaft; 8, support; 9, the strong point.

The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.

Embodiment 1:

As shown in Figure 1; Transmission device in a kind of lock core rotating mechanism; Comprise motor 6, motor-driven worm screw 5, driven the driving block 1 that the transmission component drive is moved by worm screw 5; It is characterized in that said transmission component is that one one end cooperates promotion driving block 1 with driving block, the other end cooperates the rotation with worm screw 5 to be converted into linearly moving rubber-like fold-type member with worm screw 5.Can be together or disengaging wedging state after driving block 1 moves with driving-chain base 2 wedgings.

Said fold-type member is the parts of global formation; Position in the bending of fold-type member has a strong point 9; The said strong point 9 is supported by a support 8, is exactly the other end that is moved forward and backward by drive along with worm screw 5 rotation meetings that is stuck in worm screw 5 screw threads under the strong point 9.

In the practical case of reality; The two ends of fold-type member keep being roughly the angle at right angle; The axial direction of worm screw is vertical with the direction that driving block need move, thus the clear and definite angle of fold-type member, the strong point in the middle of the fold-type member; Through the strong point by the rack shaft frame on support, so the fold-type member can be that fulcrum is rotated with the rack shaft.

Embodiment 2:

Embodiment 2 is that with embodiment 1 scheme difference when said fold-type member was crimp 3 and shelves bar parts 4 formations, crimp 3 just played by the rack shaft frame on support; Lower end and shelves bar parts 4 interlocks that are stuck in the worm screw, so-called shelves bar parts 4 present card frame type, and mid portion is stuck on the worm thread; The both sides extension then with crimp 3 socket connections; An end that drives crimp 3 moves forward and backward, and then through lever principle, the other end just can move up and down.
