Description

Self-opening door mailbox electric lock

Technical field

The utility model relates to a kind of bin electric lock, the P.O. Box electric lock that can open chamber door automatically after particularly a kind of the unblanking.

Background technology

Traditional P.O. Box adopts more changes core bin lock, padlock.Existing mechanical is changeed the core lock, the padlock existence is easy to be dialled sled, stops up the problem of keyhole.Can't supporting realization postal letter, the networking of logistics, digital management.It is comparatively complicated that the machinery of traditional P.O. Box lock changes core lock, pad lock structure, be to be the key inlet port at the lock core front end, establish key groove hole in the lock core, the slotted eye upper end is provided with the pellet shot from a slingshot hole, lock core is positioned at lock tube, the corresponding lock core marble hole of lock tube also is provided with the pellet shot from a slingshot hole, be provided with one deck pellet shot from a slingshot in the pellet shot from a slingshot hole in the lock core, the corresponding one deck pellet shot from a slingshot in pellet shot from a slingshot hole in the lock tube is provided with two layers of pellet shot from a slingshot, two layers of pellet shot from a slingshot rear end are provided with one or two layers of pellet shot from a slingshot of spring roof pressure, the spring outer end is enclosed on the lock body, and the lock core rear end is provided with opening pin, opens lock in order to stir dead bolt.When on the key teeth make gap between one deck pellet shot from a slingshot and the two layers of pellet shot from a slingshot just in time when lock core is parallel with the gap between the lock tube, key drives lock core and rotates and drive lock and open, on the contrary one or two layers of pellet shot from a slingshot interlace, lock core can not be rotated.This destroys lock for robber person and brings convenience, robber person applies power to lock core to the direction of unblanking with driving lever, apply sled with one deck pellet shot from a slingshot in the wire drawing pole pair lock core again and dial power, make gap between one deck pellet shot from a slingshot and the two layers of pellet shot from a slingshot just in time when lock core is parallel with the gap between the lock tube, lock can be opened.The mailbox lock mostly is open-air use, and keyhole often takes place to be caused the lockset damage to lose efficacy by injecting glue, obstruction foreign matter.Along with development and national economy, postal management realizes that networking, systematized process just begin.Be badly in need of a kind of simple in structure, price is low, weather proof, robust electric lock.

Summary of the invention

The purpose of this utility model is a kind of self-opening door mailbox electric lock of design, have volume little, simple in structure, easy to use, adapt in the open use, theftproof performance is good, cheap and the advantage of long service life.For this reason, the utility model adopts latch hook to be located in the lock housing by the lock hook shaft axle, be arranged with the latch hook back-moving spring on the lock hook shaft, the latch hook front end is provided with the hook groove, latch hook lower end inner face is provided with and ejects the arc limit, set firmly cam on the motor shaft of DC speed-reducing, cam holds on outside, latch hook lower end, and two dead bolt bearing front end axles on the dead bolt seat are provided with the dead bolt axle.The said structure design has realized the purpose of this utility model.

The utility model has the advantages that: volume is little, simple in structure, easy to use, adaptation is used in the open, theftproof performance is good, cheap and long service life.The utility model uses smart card or the instruction of other signal of telecommunication to unblank, and does not have mechanical key, can effectively take precautions against illegal technological means and unblank, the supporting realization postal letter of energy, the networking of logistics, digital management.

The specific embodiment

To shown in Figure 2, a kind of self-opening door mailbox electric lock mainly is made up of dead bolt seat 15, lock housing 8, latch hook 2 and DC speed-reducing 17 as Fig. 1.Latch hook is located in the lock housing by 4 of lock hook shafts, is arranged with latch hook back-moving spring 5 on the lock hook shaft, and the latch hook front end is provided with hook groove 13, and latch hook lower end inner face is provided with and ejects arc limit 10.Set firmly cam 6 on the motor shaft 9 of DC speed-reducing, cam holds on outside, latch hook lower end.Two dead bolt bearings, 1 front end axle on the dead bolt seat is provided with dead bolt axle 14.Be provided with limit switch 3 in the lock housing of latch hook upper end, the latch hook upper end is provided with the fore-set 7 that opens and closes this limit switch.Described DC speed-reducing is positioned at outside the lock housing.The DC speed-reducing casing is fixed as one with corresponding lock housing, and motor shaft then passes the affixed cam that is positioned at lock housing of lock housing.

Described lock housing front end is provided with locking board 12, and locking board is provided with for ejecting the solid lath hole 11 of arc while wearing on dead bolt axle and the latch hook.The locking board rear and front end is provided with screw 16, for lock housing is fixed on mailbox inside door side.

Described hook front of the slot face is the inclined-plane.To make things convenient for the dead bolt axle, make in the hook groove of dead bolt axle jacking latch hook latch hook jack-up.

During use, lock housing is fixed on mailbox inside door side, the dead bolt seat is installed on the locked groove position in the corresponding lock housing of mailbox door.During locking, close the mailbox door, the dead bolt axle of dead bolt bearing front end passes the inclined-plane that solid lath hole holds hook front of the slot face, slips in the hook groove with latch hook jack-up and along this inclined-plane, the hook groove is pressed in the dead bolt thrust collar in this groove under the effect of latch hook return spring, and chamber door is locked and finished.

When unblanking, DC speed-reducing drives cam rotation, and cam holds stirs outside, latch hook lower end and with the latch hook jack-up that makes progress, make latch hook with the lock hook shaft be the axle center upwards, promptly upwards pluck and take off the dead bolt direction of principal axis and turn to the dead bolt axle and deviate from the hook groove, realize unblanking.Simultaneously, when the dead bolt axle was deviate from the hook groove, latch hook lower end inner face is provided with ejected the arc limit and also ejects from solid lath hole chamber door is opened.DC speed-reducing drives cam and continues to stir latch hook and go to the linear section of cam outer contour until the latch hook bottom, and latch hook is subjected to the effect of latch hook return spring opposite force, and latch hook is reversed to initial position in the other direction, prepares to lock next time.The fore-set of latch hook upper end projection is depressed limit switch this moment, and the information uploading that door is opened is to controller, and the controller DC speed-reducing of cutting off the electricity supply stops operating, and has so far finished and has unblanked, opens the door.Obviously, latch hook resets and prepares to lock next time and to cut off the implementation process of the power supply of DC speed-reducing, is by the shape of cam and latch hook, size, kind of drive decision.

Obviously, the utility model uses smart card or the instruction of other signal of telecommunication to unblank, and does not have mechanical key, can effectively take precautions against illegal technological means and unblank.The utility model is to rely on DC speed-reducing to drive cam rotation, the latch hook action is finished, DC speed-reducing relies on direct current or rectifier power source to rotate, and only receives the Intelligent Recognition signal of telecommunication instruction of unblanking and is located at controller in the casing and just connects the DC speed-reducing power drives and unblank.And the controller that opens and closes control DC speed-reducing power supply can be automatically controlled scrambler, remote controller or connects yard device etc., so be not repeated.

In a word, the utlity model has volume little, simple in structure, easy to use, adapt to use in the open, anti-Steal the advantage of functional, cheap and long service life. Can promote the use of.
