Description

Electronic lock

Technical field

The utility model relates to door lock, especially a kind of electronic lock.

Background technology

Existing electronic lock, mainly by accumulate pond, remote-control motor, electric bolt and remote-control key form.Electronic lock is arranged on doorframe middle part one side, and the lower end of gate flap and upper end fill respectively a plug, and two plugs are separate, and without connecting, its shortcoming one is that the manner between motor and electric bolt is inconsistent, and internal structure of motor is more complicated; The 2nd, upper bolt with move back bolt and need hand to stir plug, trouble wastes time and energy.

Utility model content

The purpose of this utility model is to provide a kind of electronic lock, and the entering and move back of remote control three bolts disposablely completes locking and unblanking of three bolts.

The technical solution of the utility model is: electronic lock, comprise remote-control motor, remote-control key, locking bolt, spring on doorframe, remote-control motor is electrically connected with accumulate pond, has motor shaft in remote-control motor, motor shaft lower end is provided with a screw rod, and screw rod inserts square nut bolt screw-internal thread fit; Square nut bolt has a square bolt cover outward, and there is a screw rod major part top, square nut bolt bottom contact one push rod, and push rod overcoat has spring, and push rod lower end is flexibly connected a cam bolt and a long locking bolt by a tailing axle; Cam bolt can insert the lockhole at door leaf or doorframe middle part under push rod and spring action, and long locking bolt inserts the lower lockhole of doorframe, and square nut bolt can insert the upper lockhole of door leaf top.

The utlity model has following good effect: the one, remote-control motor is synchronizeed again in the same way with the activity of screw rod, and internal structure of motor is simple; The 2nd, omnidistance electronization, the remote-controlled synchronous opening/closing of three locking bolts; The 3rd, not only can be used for simple gate but also can be used for two-doorly, theftproof performance is strong.

In figure: 1-accumulate pond, 2-remote-control motor, 3-motor shaft, 4-screw rod, 5-square nut bolt, the square bolt cover of 6-, 7-push rod, 8-spring, the long locking bolt of 9-, 10-cam bolt, 11-camshaft, 12-tailing axle, the upper lockhole of 13-, lockhole in 14-, lockhole under 15-, the large gate flap of 16-, 17-screw rod major part, 18-doorframe.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is elaborated:

Please see Figure 1, electronic lock, is mainly made up of remote-control motor device, screw-and-nut mechanism, company's stud structure three parts.Remote-control motor device comprises accumulate pond 1, remote-control motor 2, remote-control key.In remote-control motor 2, have the motor shaft 3 of positive and negative rotation, remote-control motor 2 is positioned at doorframe 18 tops, and remote-control motor 2 is electrically connected with accumulate pond 1.Motor shaft 3 lower ends are provided with a screw rod 4, and screw rod 4 inserts square nut bolt 5 screw-internal thread fit; Square nut bolt 5 is outer has a square bolt to overlap 6, and there is a screw rod major part 17 top, and square nut bolt 5 bottoms can contact a push rod 7, and push rod 7 overcoats have spring 8, and push rod 7 lower ends are flexibly connected a cam bolt 10 and a long locking bolt 9 by a tailing axle 12; Cam bolt 10 can insert the middle lockhole 14 at door leaf or doorframe middle part under push rod 7 and spring 8 effects, and long locking bolt 9 can insert the lower lockhole 15 of doorframe, and square nut bolt 5 can insert the upper lockhole 13 of door leaf 16 tops.

Please see Figure 2, bolt and nut structure is positioned at large gate flap 16 inside, push rod 7 overcoats have spring 8, push rod 7 lower ends are flexibly connected a cam bolt 10 and a long locking bolt 9 by a tailing axle 12, the door leaf place corresponding with cam bolt 10 has cam keyhole, camshaft 11, for fulcrum cam bolt 10 under push rod 7 drives rotates, makes cam bolt 10 insert or exit middle lockhole 14.

In the time that electronic lock is loaded on doudle leaf door, have middle lockhole 14 at middle part, wicket leaf side, large gate flap top has lockhole 13, bottom has lower lockhole 15, electronic lock is loaded on doorframe center top by large gate flap one side, and bolt and nut structure steganography is in large gate flap 16 left frames, and long locking bolt 9 is aimed at the lower lockhole 15 of doorframe 18 bottoms, square bolt cover 6 is aimed at the upper lockhole 13 of doorframe, and cam bolt 10 dead bolts are aimed at the middle lockhole 14 of wicket leaf side.

Lock and unblank process: while locking, first will be large, little two door leafs are closed in doorframe, press the pass button of remote-control key, accumulate pond 1 starts remote-control motor 2, motor shaft 3 rotates counterclockwise and drives screw rod major part 17, the backwards rotation such as screw rod 4, it is downward that the screw thread of screw rod 4 promotes square nut bolt 5, square nut bolt 5 promotes push rod 7 and spring 8 downwards simultaneously, push rod 7 drives tailing axle 12, tailing axle promotes long locking bolt 9 downwards, under the effect of camshaft 11, lockhole 14 during the dead bolt of cam bolt 10 inserts to upper left side, in the time that 5 times sections, square nut bolt enters upper lockhole 13, push rod 7 and spring 8 are depressed to lockhole 15 under the lower section of insertion that makes long locking bolt 9, now on large gate flap, the middle part of bottom and little gate flap is locked simultaneously.

While unblanking, press the button of opening of remote-control key, storage start battery remote-control motor 2, motor shaft 3 moves in the direction of the clock, motor shaft 3 drives screw rod major part 17, screw rod 4 clockwise, and screw rod 4 upwards draws square nut bolt 5, and square nut bolt 5 exits lockhole 13 and enters in square bolt cover 6.Spring 8 promotes push rod 7 upwards and enters 13 inside, hole of locking, and long locking bolt 9 upwards exits lower lockhole 15 and enter the inner chamber of large gate flap, and the dead bolt of cam bolt 10 exits middle lockhole 14.All locking bolt is opened, two-door opening.
