Detailed Description

In order to further understand the present invention, the following detailed description will be given with reference to the specific embodiments.

As shown in fig. 1-5, according to the utility model discloses a timing unlocking device, including unlocking device casing 1, time-recorder 2, host system, motor drive, including a motor, an end cap, a controller, and a cover plate, the battery, spring lock 4 and bolt 5, time-recorder 2 and motor drive are connected with host system respectively, host system further is connected with the battery, motor drive further is connected with motor 3, motor 3's output shaft and spring lock 4 are connected, in order to control the up-and-down motion of spring lock 4, partly insert in unlocking device casing 1 of bolt 5, and cooperate with spring lock 41 on the spring lock 4, when spring lock 41 moves down, bolt 5 pops out from unlocking device casing 1.

Through the timing setting of timer 2, when the time that reachs the setting, host system passes through motor drive driving motor 3 to 4 unblocks in the control spring locking, make the bolt 5 of connecting in wire rope one end pop out regularly, realize regularly accurate unblock, wire rope is unbound the back, and the leaflet is just put in appointed input point, puts in accurately. Only the time on the timer needs to be set in advance, so that the manual participation is reduced, and the manpower is saved.

Further, the plug pin 5 includes an insertion tube 51, an insertion post and a socket 52, the insertion tube 51 is connected with the socket 52 through the insertion post, and an edge portion of the top surface of the socket 52 is matched with the latch tongue 41; the latch tongue 41 is fitted to an edge portion of the socket 52, and the latch 5 can be fixed in the housing of the unlocking device by such a structural arrangement, preventing the latch 5 from falling off.
