Abstract

The invention discloses a locking device and is characterized in that the locking device comprises a locking member and a driving shaft connected with a driving device, wherein the locking member comprises a driving part and a locking part which are fixedly connected with each other. The driving part is hollow and arranged on the driving shaft. A spring is sleeved around the driving shaft and abutted against the inner surface of the driving part. A pin is provided on the driving shaft and vertical to the axial direction, and is engaged with the spring. Since the structure is simple and the kinetic resistance of driving shaft and locking member is small, the driving device is required to provide a small power and the power consumption is low, the driving device can work repeatedly for more than 100,000 times even powered on four dry batteries with the general capacity. The inventive locking device is widely used in various locksets.

Description

A kind of locking device

Technical field

The present invention relates to a kind of locking device that is used on the lockset.Especially the locking device on a kind of electric control lockset.

Background technology

The key that existing lockset generally all needs to match can be opened, but all there is certain defective in these mechanical locksets, so the people who also exists some that lock structure is very familiar in the society, even utilize some lockset design defect not use the key that matches also can open lockset.In order to address the above problem, on the market a kind of electric control lock has appearred now, at first will lead and lock with key or automatically controlled form, at the other secondary locking device that also is provided with of main lock, the general lock core that adopts automatically controlled form will lead lock is locked, and this electric control gear generally adopts electronic cipher to encrypt, and is being provided with electron key on the key in addition accordingly, when unblanking, need utilize electron key to open the secondary locking device earlier, will could lock with key operated master after the main lock pin release.Because electron key adopts electronic technology to encrypt, and generally is difficult to crack at short notice, so just can increase the reliability of lockset greatly.But, because this electric control lock need be powered and could be used, if and the door that lockset is installed waits the employing line powered unreasonable, influence is used, generally still adopt dry cell or battery to power, in case but battery electric quantity exhausts and will cause electric control lock out of control, whole lockset can't be opened, so power consumption of secondary locking device design, comprise the power consumption that circuit and frame for movement produce, will have influence on the practicality of lockset, and all very complicated power consumption of respective electronic drive unit that causes of the frame for movement of present secondary locking device increases, influenced the application of lockset, often changed battery as needs and cause trouble or use high capacity cell to increase cost.

Summary of the invention

The object of the present invention is to provide a kind of locking device, simple in structure, power consumption is lower, make lockset practical more, reliable.

The present invention realizes above-mentioned purpose like this:

A kind of locking device, it is characterized in that comprising locking piece and the driving shaft that links to each other with drive unit, wherein locking piece comprises fixedly connected drive part and lock part, described drive part hollow also is installed on the driving shaft, there is spring housing to be connected on the driving shaft and withstands on the inner surface of drive part, driving shaft is provided with pin, this pin and spring interlock on vertical and axis direction.

The invention has the beneficial effects as follows: drive unit drives the driving shaft rotation, thereby the pin on the axle makes the spring partial compression drive locking piece and moves, realize the locking or the release of main lock pin, because structure is very simple, and driving shaft, the resistances of motion such as locking piece are little, therefore the driving power that needs drive unit to provide is very little, power consumption is very low, even use four joint dry cells of common capacity also can repeat work more than 100,000 times, simultaneously also because structure simple, when locking piece moves to stroke terminal, the pin and the spring of driving shaft skid, be unlikely to that driving shaft is stuck and cause the damage of drive unit or miscellaneous part, improved the reliability that this device uses greatly, the locking device that is unlikely to cause main lock pin to be lost efficacy is given locked.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the opening figure of application example of the present invention;

Fig. 3 is the lock-out state figure of application example of the present invention.

The specific embodiment

With reference to Fig. 1, a kind of locking device, comprise locking piece 1 and the driving shaft 2 that links to each other with drive unit 3, wherein locking piece 1 comprises fixedly connected drive part 11 and lock part 12, described drive part 11 hollows also are installed on the driving shaft 2, have spring 13 to be socketed on the driving shaft 2 and withstand on the inner surface of drive part 11, driving shaft 2 is being provided with pin 21, these pin 21 and spring 13 interlocks on vertical and axis direction.Drive unit 3 drives driving shaft 2 rotations, moves thereby the pin on the axle 21 makes spring 13 partial compression drive locking piece 1, realizes the locking or the release of main lock pin.

Described drive unit 3 can have various ways, the preferential specific embodiment that adopts of the present invention drives for adopting motor 31, the output shaft of motor 31 is equipped with driving gear 32, on driving shaft 2, be provided with driven gear 22 accordingly, motor 31 links to each other the very simple compactness of structure by the driving and driven

gear

32,22 of engagement with driving shaft 2.Certainly as required, change above-mentioned driving and driven

gear

32,22 into gearbox, the actuating speed of motor 31 can make corresponding changes like this.

For the ease of installing and selling, the parts of this device are installed in the housing 4, and housing 4 is provided with the hole in the 12 corresponding places, lock part of locking piece, and stretch out from this hole the lock part 12 of locking piece.

With reference to Fig. 2, Fig. 3, this locking device is installed in the relevant position of lockset, the basic structure of existing lockset is dead bolt 5, lock core and dead bolt locking plate 6 etc., generally be by opening the unlatching of lock core rear drive dead bolt 5 withdrawal realization locksets, dead bolt locking plate 6 then can lock dead bolt 5, still can not make dead bolt 5 withdrawals even if lock core is opened, realize back locking function.And the lockset that this device is housed can be realized the secondary locking by the control to dead bolt locking plate 6.The lock part 12 of locking piece is provided with locking activity template 13, and under this device opening, locking activity template 13 breaks away from dead bolt locking plate 6, can open lockset as long as open lock core; If under this device lock-out state, locking activity template 13 is locked in dead bolt locking plate 6 position of locking, lockset is locked, if unlatching lockset, can only by electron key with the release of this locking device after, make motor 31 drive locking piece 1 and move that allow locking activity template 13 and dead bolt locking plate 6 break away from, releasing is locked state and got final product.

Because the structure of this device is very simple, and driving shaft 2, the resistances of motion such as locking piece 1 are little, therefore the driving power that needs drive unit 3 to provide is very little, power consumption is very low, even use four joint dry cells of common capacity also can repeat work more than 100,000 times, also have simultaneously because structure simple, when locking piece 1 moves to stroke terminal, the pin 21 and the spring 13 of driving shaft skid, be unlikely to that driving shaft 2 is stuck and cause the damage of drive unit 3 or miscellaneous part, improved the reliability that this device uses greatly, the locking device that is unlikely to cause main lock pin to be lost efficacy is given locked.
