Description

A kind of electronic lock

[technical field]

The utility model belongs to lockset manufacturing technology field, particularly a kind of electronic lock that is applied to cabinet, drawer.

[background technology]

As everyone knows, being locked in has purposes very widely in the daily life, and it is a kind of requisite safety apparatus, and it brings safety guarantee for people's property.

Traditional lock all adopts mechanical type; though mechanical lock is easy and simple to handle, cheap; but it is poor stability not only, and need wear key, brings awkward problem to the user; What is more; the phenomenon of key appears losing in user regular meeting, in case lose key, just needs more to renew lock; make troubles not only to user's cost of increasing expenditure, and to the user.

At present, some electronic locks occurred, though existing electronic lock has overcome the poor stability that traditional mechanical is latched in, used the problem that bothers, also there are some defectives in present electronic lock.At first, the complex structure of existing electronic lock, its production, installation and attended operation process trouble, and also difficulty is big; Secondly, cost cost height, average family can't bear the price of existing electronic lock at present, makes that existing electronic lock can't popularization and application.

[summary of the invention]

The utility model discloses a kind of electronic lock, it has solved existing electronic lock and has had complex structure, technical matters that the cost cost is high.

The technical solution of the utility model is as follows: a kind of electronic lock, comprise housing, and establish dead bolt, retainer spring, single-chip microcomputer in the housing, dead bolt one end stretches out outside the housing, after locking or unblanking, is located by retainer spring, establish a knob on the housing, knob is by gear and dead bolt engagement; Establish driving machine in the housing, driving machine links to each other with an inserted link, and single-chip microcomputer is defeated by the driving machine signal, and driving machine drives the jack on inserted link insertion or the disengaging dead bolt.

Described electronic lock is established a rotating main off-centre in the housing, establish the main eccentric groove that drives on the dead bolt, main eccentric upper end is stretched into and is driven in the groove, and this end connects a locking bar, and locking bar stretches out outside the housing, be connected in main eccentric locking bar and rotate, realize secondary locking with moving of dead bolt.

Described electronic lock, described driving machine are motor.

The utility model electronic lock is applicable to fields such as cabinet, drawer, its have simple in structure, lock body is little, accurate positioning, easy and simple to handle, safe, advantage that cost is low, produce, install, safeguard easier, and can be born by average family, can the penetration and promotion application.

In addition,, then can connect a long locking bar on the utility model electronic lock main eccentric, be used for secondary locking cabinet door, thereby further strengthen the security of this electronic lock if the cabinet door is long.

Fig. 3 is partial structurtes figure of the present utility model.

Fig. 4 is a three-dimensional structure diagram of the present utility model.

[embodiment]

Below in conjunction with accompanying drawing the utility model is elaborated.

Shown in Fig. 1-4, establish single-chip microcomputer, battery etc. in the housing 4 of this electronic lock, single-chip microcomputer output control signal, battery provides power supply, and battery is suppressed by the battery cover 5 at housing rear portion, and cipher cover 1 is established in the housing front portion, establish USB interface on the cipher cover 1, be used to transmit data, it is covered by USB cover 13.Pass a knob 12 on the cipher cover 1, knob 12 is affixed with the gear 11 in the housing.Housing one side is offered slide opening, and an end of the dead bolt 8 in the housing stretches out outside the slide opening of housing one side, and dead bolt 8 can be along the slide opening translation; Establish teeth on the dead bolt 8, with gear 11 engagements.Dead bolt 8 links to each other with retainer spring 9, and the other end of spring 9 is fixed in housing 4 inwalls.Dead bolt 8 is established a jack 16, this jack 16 stretches into a clutch inserted link 14, the bottom of clutch inserted link 14 links to each other with a pushing block, pushing block links to each other with a spring, stretch into one in the spring, axle links to each other with the motor shaft of clutch motor 10 by twice deceleration, and clutch inserted link 10 drives lower edge tracks 15 at motor 10 and makes upper and lower translation and move and stretch into or break away from jack 16.

Also establish the main eccentric groove 7 that drives on the dead bolt 8, stretch into the eccentric top 6 of master in the groove 7, the lower end on main eccentric top 6 is interlockingly connected with main eccentric bottom 2 and forms main off-centre; Set firmly a transverse slat in the housing, offer a rotating hole 3 on the transverse slat, main eccentric bottom 2 places rotating hole 3 and rotatable.Main eccentric top 6 connects a long locking bar (not drawing among the figure), and long locking bar stretches out the top of housing 4.When the cabinet door is long, but this long locking bar secondary locking cabinet door, and further the firmness of reinforcement locking strengthens security.

Be in the lock state down, clutch inserted link 14 inserts the jack 16 on the dead bolts, and therefore, dead bolt 8 is stopped by inserted link 14 and back and forth movement automatically.When the input password and behind system validation, single-chip microcomputer is given 10 1 starting-up signals of clutch motor, clutch motor 10 drives clutch inserted link 14 and moves downward along track 15, the jack 16 that clutch inserted link 14 breaks away from the dead bolt, at this moment, turning knob 12 drives knob gear 11 and rotates, and then make the dead bolt 8 that meshes with gear 11 in slide opening, do the motion that moves inward, can realize unblanking.After retainer spring 9 pushed away the middle part, just pull back, promptly be positioned after unblanking.Behind the location, 10 counter-rotatings of system design clutch motor move upward thereby promote inserted link 14, and until inserting jack 16, inserted link 14 stops that dead bolt 8 outwards moves.

When locking, input password and behind system validation, single-chip microcomputer is given 10 1 signals of clutch motor, and motor 10 drives inserted links 14 and moves downward, until the jack 16 that breaks away from the dead bolt; Then, toward counter-rotation knob 12, knob gear 11 rotates drive dead bolt 8 and outwards moves, put in place until dead bolt 8 lockings, after several seconds, motor 10 counter-rotatings are under the driving of clutch motor 10, clutch inserted link 14 rises until inserting jack 16, stop dead bolt 8 once more, can realize locking that retainer spring 9 was after other direction pushed away the middle part, just push away forward, promptly be positioned after locking.

If the cabinet door is oversize, can connect a long locking bar on main eccentric top 6, be used for secondary locking cabinet door.When dead bolt 8 is mobile with the rotation of knob 12, to lock from unblanking to or unblank from being locked into, main eccentric the drive in main off-centre turns over 90 degree forward or backwards in the groove 7, together lock or unblank with dead bolt 8, thereby play the effect of auxiliary lock fixed length cabinet door.
