Abstract

The utility model discloses a clock-controlled lock used in the safe case and the file cabinet, belonging to the time safety device, and solves the defect that the existing safe case and file cabinet can be opened without the limitation of the time and can alarm if being opened in the locking time. The utility model is characterized in that the a 24 hours clock is used to control a cylinder lock controlled by an electric magnet and is provided with two groups of power switches comprising a time hand and an hour hand to control the action of the electric magnet which can control the rotation of the lock core of the cylinder lock.

Description

Clock-controlled lock

The utility model relates to a kind of door lock.Be particularly useful for a kind of clock control lock of safety cabinet and file cabinet.Belong to a kind of time safeties.

Used various locks are not controlled by the time now, can open with key any time, like this, as long as the robber has had key just can do case when the no one notes.

The purpose of this utility model provide a kind of only could be with key operated lock in the specific time.If drawback lock At All Other Times just report to the police at once prevent stolen.

Task of the present utility model is finished like this.Clock-controlled lock is made up of the clock of 24 hours system and the cylinder lock of carry magnet.Be provided with 2 groups of timing pointers in the clock and an electromagnet is set on lock body.Time pin separates two groups of lockings, forms power switch with hour hands by the contact, the control electromagnet.Control the rotation of lock core by the motion bar of electromagnet.The motion bar center of electromagnet is provided with the copper core, and key inserts lock core and just contacts the formation alarm switch with the copper core when locking

Referring now to the description of drawings embodiments of the invention.Time pin adopts metal material to make, on establish contact 12(such as Fig. 1,2).The locking time pin 5 and the time pin 6 of unblanking are pressed on the hollow shaft made from insulation materials 8 by stage clip 9 and retainer 11.Be provided with a felt pad 10 in the middle of two groups of

time pins

5,6 and make it mutually insulated, and all locate in one plane.For several times of many control, can establish several pointers for every group and be enclosed within on the hollow shaft 8.As Fig. 1,2,3 is every group of 2 pointers.Locking time pin 5 is drawn lead 13 with the time pin 6 of unblanking by stage clip 9 and retainer 11 and is connected with electromagnet coil lead-in

wire

13,14 with 14.

Hollow shaft

8 and 7 riveted joints of clock and watch frame.Hour hands 4 reverse side are provided with contact 12 and form power switch with time pin contact 12.

Electromagnet is made up of magnetic core 17,

coil

18,19, motion bar 16, shell 15.Shell 15 ends and lock body 23 are fixing.Motion bar 16 usefulness hard insulations are made, and the center is provided with copper core 24, draws with lead 22.When hour hands 4 and time pin 5 are overlapping, contact 12 conductings, coil 18 electric, motion bar 16 is inhaled down, jump ring 27 is stuck in the motion bar draw-in groove 26, lock core 20 and lock body 23 is inserted be one, key can not turn.At this moment, copper core 24 forms an alarm switch by key 21 and lock body 23, becomes alarm condition.When hour hands 4 and time pin 6 are overlapping, contact 12 conducting coils 19 electric, motion bar 16 is sucted, jump ring 27 is stuck on the motion bar draw-in groove 25, makes it fixing, at this moment motion bar 16 is extracted from lock core 20, key can turn, and promptly locks to be opened.

Electromagnet described in the utility model is with the fixing motion bar two kinds of duties up and down of jump ring, so when hour hands are passed by time pin, still can maintain the original state behind the coil losing electricity.

Clock described in the utility model is the electronic indicator clock.1 dial plate among the figure, 2 second hands, 3 minute hands.17 magnetic cores.

Claims

1, a kind of clock control lock is specially adapted to safety cabinet, file cabinet etc., it is characterized in that it being clock by 24 hours system, the cylinder lock of a charged magnet of control is formed, the motion bar center of described electromagnet is provided with the copper core, and it contacts with key when locking, forms alarm switch.

2, clock control lock according to claim 1, the clock that it is characterized in that described 24 hours systems is made up of for the hour hands 4 of contact and common minute hand 3 and second hand 2 two groups of time pins 5,6 for contact 12, back, when hour hands 4 turn to the position of time pin 5,6, the contact 12 of two pins is in contact with one another, form power switch, the action of control electromagnet.

3, clock control lock according to claim 2, it is characterized in that described two groups of time pins for the contact by retainer 11, form, retainer 11, all be fixed on the clock core by hollow shaft 8 for time pin 5,6, felt pad 10, the stage clip 9 of contact 12 for time pin 5,6, felt pad 10, stage clip 9, the hollow shaft 8 of contact 12.

4, clock control lock according to claim 1, the cylinder lock that it is characterized in that described generation electromagnet is made up of coil 18,19, magnetic core 17, motion bar 16, jump ring 27, shell 15, pin tumbler lock body 23, core 21, coil 18,19, magnetic core 17, motion bar 16, jump ring 27 all are fixed in the shell 15, and the fixed screw by shell 15 is fixed on the pin tumbler lock body 23.
