Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: as shown in fig. 1 to 6, a three-way electronic lock comprises a housing 1, a fixed motor 2 and a movable locking piece 4 which can protrude towards the side edge are arranged in the housing 1, the output shaft of the motor 2 is provided with a driving gear 21, the driving gear 21 is engaged with an upper rack part 32 positioned at the top of the movable plate 3, the movable plate 3 is provided in the case 1 and restricted to move only linearly, a notch is provided in the middle of the movable plate 3 and an inner rack portion 33 is provided at a side of the notch, the inner rack portion 33 is connected to a second gear provided on the turntable 7 by meshing, the turntable 7 is rotatably provided in the housing 1, the rotary disc 7 is provided with a positioning pin 71, the locking sheet 4 is provided with a guide groove 42 vertical to the displacement direction of the locking sheet, the positioning pin 71 moves in the guide groove 42 and acts on the groove wall in the guide groove 42 to drive the locking piece 4 to displace; the tail end of the locking piece 4 is provided with a semicircular limiting notch 411, and the moving end point of the positioning pin 71 is the limiting notch 411.
The bottom of the movable plate 3 is connected with a transverse plate 34, two ends of the transverse plate 34 are provided with clamping grooves 341, the clamping grooves 341 are provided with locking columns 5, and the locking columns 5 can extend out of the shell 1 to complete locking work.
The number of the positioning pins 71 is two, and the positioning pins are symmetrically arranged on the same diameter of the turntable 7; the number of the locking pieces 4 is two, and the displacement directions of the two locking pieces are opposite; the positioning pins are matched with the locking pieces to work in a one-to-one correspondence mode.
The locking piece 4 is provided with a narrow part 41 with a reduced width, the narrow parts 41 of the two locking pieces 4 are mutually attached and slide, and the joint of the narrow part 41 and the normal width of the locking piece 4 limits the maximum displacement of the other narrow part 41.
A mechanical unlocking mechanism 6 is arranged in the shell 1, the mechanical unlocking mechanism 6 is provided with a shifting piece 61, and the shifting piece 61 can be driven to rotate after unlocking; the movable plate 3 is provided with a stop lever 31, and the rotation of the shifting sheet 61 can drive the stop lever 31 to move upwards so as to drive the movable plate 3 to move upwards.
The blocking lever 31 is perpendicular to the movable plate 3. So arranged, it is convenient to use the stop lever 31 to drive the movable plate 3 to move.
The transverse plate 34 is provided with a plurality of limiting guide clamping blocks 342, the shell 1 is internally provided with a plurality of guide grooves, and the limiting guide clamping blocks 342 are clamped in the guide grooves to slide. With the arrangement, the transverse plate 32 can be prevented from shifting, so that the situation of 'clamping' in the shell is caused.
The bottom of the shell 1 is provided with a protective sleeve 11, and the locking column 5 is sleeved in the protective sleeve 11. The protective sleeve 11 is sleeved outside the locking column 5, firstly can protect the outer surface of the locking column 5, and secondly can generate a guiding effect. Because of the wall thickness of the housing, it cannot provide sufficient guidance for the locking cylinder 5, so that jamming can occur during the displacement of the locking cylinder 5. And the protection sleeve 11 with enough length is adopted, so that the 'smoothness' of the locking column in the moving process can be ensured.
The device utilizes a motor to drive a movable plate 3 to move, a locking column 5 is arranged below the movable plate 3, when the locking column 5 extends out, the locking is realized, and when the locking column retracts, the unlocking is realized. The movable plate 3 is further provided with an inner toothed bar portion 33, and the turntable 7 is driven to rotate by the inner toothed bar portion 33. In the unlocked state, the two positioning pins 71 are located on a vertical line. When the movable plate 3 moves down, the turntable 7 rotates, so that the positioning pin 71 is displaced. The locating pin of top rotates downwards, and the below is then upwards. After the positioning pin 71 rotates, it acts on the groove wall in the guide groove 42 to push out the locking piece 4, thereby performing the locking operation. When the two positioning pins 71 are rotated to the horizontal position, they fall into the limiting notches 411 of the opposite locking piece 4. The stopper notch 411 obstructs the further movement of the positioning pin 71, and thus the locking work is completed.
When the unlocking is carried out, the motor rotates reversely, and the work of the parts in the device is opposite to that of the parts.
The device has a mechanical unlocking mode. Wherein it is necessary to insert the mechanical unlocking mechanism 6 with a key. If the key is satisfactory, the mechanical unlocking mechanism 6 is unlocked and then rotated, thereby driving the rotation of the paddle 61. When the shifting piece 61 rotates, it abuts against the stop lever 31 and drives the stop lever 31 to move upward. The blocking rod 31 is fixedly arranged on the movable plate 3. Therefore, the movable plate 3 can be driven to move upwards, the movement of the internal parts is consistent with the unlocking of the motor, and the mechanical unlocking is finally completed.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
