Abstract

The utility model discloses a transmission device for an automatic lockset, which is improved by aiming at the problems of transmission devices of the existing automatic locks and the existing electric control locksets. A transmission member is arranged on structures of a door leaf, a door frame and a hinge, and power in the process of closing doors can be transmitted to a lock bolt through an energy accumulating spring to make a lock locked out. The transmission device is additionally provided with a restoring spring of the lock bolt for making the lock bolt retracted into a lock body, and a locking transmission course and an unlocking transmission course can be achieved without direct operation by hand.

Description

A kind of transmission device of lock

The utility model relates to lockset and makes field, a kind of transmission device of automatic lockset specifically.

At present, the automatic locking of use, electric control lock, the mode that its dead bolt kinergety obtains mainly contains two kinds: a kind of is to obtain by hand, this mode difficulty reaches electric control and finishes its entire work process; Another kind is to touch doorframe by the oblique tongue of the transmission on the electric control lock to obtain the required energy of dead bolt motion, though this mode can be used automatically controlled breakdown, resistance is bigger at closing time, is not suitable for having the complicated lockset of multidirectional lock point.

The purpose of this utility model is improved at the problems referred to above of the transmission device existence of existing automatic locking electric control lockset, and a kind of structure is reasonable more, the convenient lockset transmission device of use thereby provide.

The purpose of this utility model is achieved in that it is made up of door leaf, driving member, doorframe, hinge, lock body and dead bolt etc., described driving member is located between doorframe and the lock body, one end of driving member is connected on the accumulation of energy conduit through unlock key, the accumulation of energy conduit connects an energy-storaging spring, and unlock key withstands on a back-moving spring; In the described accumulation of energy conduit driving member back-moving spring is housed, driving member back-moving spring one end withstands on the blind end of accumulation of energy conduit, and the other end and driving head join; Be with energy-storaging spring on the described accumulation of energy conduit, an end of energy-storaging spring is stuck on the outer plush copper of accumulation of energy conduit, and the other end and dead bolt join; One guide peg is arranged in the described dead bolt, be with the dead bolt back-moving spring on it; The afterbody that one end of described guide peg passes dead bolt is fixed on the lock body; The outer end of described driving member is stretched out door leaf and is contacted on the doorframe surface, and driving member can be connecting rod, chain, wire rope; Described accumulation of energy conduit is a hollow structure, and it seals an end and is enclosed within on the dead bolt, and opening one end passes outside the lock body; Described unlock key is movably connected on the two side of accumulation of energy conduit with the unlock key rotating shaft, which is provided with positioning head and the head that resets, and an end of the head that resets withstands on the head that is fixed in the back-moving spring in the lock body; Have a groove on the described driving head; Described energy-storaging spring is contained on the driving member.

Because the utility model has been taked such scheme, increases by a transmission device, it is needed than macro-energy not only can to obtain the work of multidirectional dead bolt electric control lockset, and resistance is little at closing time, does not send the collision sound, reliable in structure.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is that lock body of the present utility model is installed in the structural representation in the door leaf;

Fig. 2 is the transmission structures schematic diagram in the lock body of the present utility model;

Fig. 3 is an accumulation of energy guide-tube structure schematic diagram of the present utility model;

Fig. 4 is a unlock key structural representation of the present utility model.

1. door leafs among the figure; 2. driving member; 3. doorframe; 4. driving head; 5. driving member back-moving spring; 6. accumulation of energy conduit; 7. plush copper; 8. back-moving spring; 9. energy-storaging spring; 10. dead bolt; 11. dead bolt back-moving spring; 12. lock body; 13. hinge; 14. unlock key; 15. positioning head; 16. unlock key rotating shaft; 17. control head; The head 18. reset; 19. guide peg.

In door leaf 1, be provided with a driving member that can slide vertically 2 among the figure, the one end stretches out door leaf 1 and joins with the doorframe 3 that is connected with hinge 13, on the driving head 4 on the driving member 2 groove is arranged, it flexibly connects with accumulation of energy conduit 6 through the positioning head 15 of unlock key 14, accumulation of energy conduit 6 is a hollow core structures, one driving key back-moving spring 5 is housed in it, the blind end of accumulation of energy conduit 6 is enclosed within on the dead bolt 10, the other end is set with driving head 4, accumulation of energy conduit 6 is connected with driving head 4 by unlock key 14, driving head 4 joins with driving member back-moving spring 5, the active force of driving member back-moving spring 5 can slide driving member 2 through driving head 4 outside door leaf 1, have one to reset and 18 withstand on the back-moving spring 8 on the unlock key 14, the other end of back-moving spring 8 is fixed on the lock body 12, the purpose of back-moving spring 8 is to reset after unlock key 14 is towed out, and is set with an energy-storaging spring 9 on accumulation of energy conduit 6, and its active force acts on respectively between accumulation of energy conduit 6 and the dead bolt 10; One guide peg 20 is arranged in the dead bolt 10 in addition, be with dead bolt back-moving spring 11 on it, the afterbody that one end of guide peg 20 passes dead bolt 10 is fixed on the lock body 12, dead bolt 10 can slide along guide peg 20 front and back, dead bolt back-moving spring 11 is stuck between dead bolt 10 and the lock body 12, and its active force can make dead bolt 10 withdrawal lock bodies 12.At closing time, door leaf 1 rotates around hinge 13 fulcrums, angle between door leaf 1 and the doorframe 3 is reduced, at this moment, driving member 2 is along door leaf 1 toward interior slip, driving head 4 on the driving member 2 promotes accumulation of energy conduit 6 through unlock key 14, because of the two ends of accumulation of energy conduit 6 are actively set on dead bolt 10 and the lock body 12, so accumulation of energy conduit 6 is by the plush copper 7 compress energy storage springs 9 on it, the effect of energy-storaging spring 9 can storage power lock out dead bolt 10 exactly, it can be contained on any position between doorframe 3 and the dead bolt 10, because the power during energy-storaging spring 9 designs is greater than the power of dead bolt back-moving spring 11, lock out needed strength so dead bolt 12 has been obtained, can lock as long as control.In the time of need unblanking, by control head 17 positioning head 15 of unlock key 14 is opened from the groove of driving head 4, thereby disconnection driving head 4 is connected with accumulation of energy conduit 6, accumulation of energy conduit 6 flicks under the effect of energy-storaging spring 9, the elastic force of energy-storaging spring 9 disappears, under the effect of dead bolt back-moving spring 11 power, in the dead bolt 10 withdrawal lock bodies 12; When opening the door, driving member 2 stretches out the door leaf certain-length under the effect of driving member back-moving spring 5, and unlock key 14 is under the effect of back-moving spring 8, and resetting again connects driving head 4 and accumulation of energy conduit 6, thereby has reached whole transmission process.

Power arm was far longer than resistance when the characteristics of the utility model utilization door itself were closed the door or opened the door The arm of force utilizes the utility model of this characteristics design can obtain the big strength of locking, unblank The time, the resistance of closing the door is little and avoided the collision sound, and reliable in structure, sturdy and durable, Improved the service life of door and doorframe.
