Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 and 4 schematically show an intelligent lock according to the utility model discloses an intelligent lock mountable on the storing cabinet.

as shown in fig. 1 to 3, the intelligent lock of the present invention includes an upper housing 1 and a lower housing 2. Go up casing 1 and casing 2 setting down on the storing cabinet, go up casing 1 and casing 2 down and pass through bolt fixed connection together, go up casing 1 and casing 2 fixed connection back inside accommodation space that forms down. A microswitch 3, a lock tongue 4, an electromagnetic driving mechanism and a lock hook 5 driven by the electromagnetic driving mechanism are arranged in the lower shell 2.

As shown in fig. 1 to 3, the microswitch 3 is provided with a swing rod 16 and a connecting hole 7. Be equipped with fixed column 6 on the casing 2 down, fixed column 6 and casing 2 integrated into one piece down, fixed column 6 and micro-gap switch 3's connecting hole 7 looks adaptation on the casing 2 down. The fixing column 6 passes through the connecting hole 7 on the micro switch 3 to fix the micro switch 3 on the lower shell 2, so that the micro switch 3 is convenient to install, convenient to manufacture and low in cost. The microswitch 3 is used for prompting the opening and closing state of the cabinet door, so that the storage cabinet is safer and more reliable.

As shown in fig. 1 to 3, the electromagnetic driving mechanism includes a core rod 8 movably installed in the hole of the electromagnet coil and a spring 9 sleeved on the core rod 8. After the electromagnet coil is electrified, magnetic force is generated, under the action of the magnetic force, the core rod 8 movably installed in the electromagnet coil hole contracts into the hole and moves upwards rapidly, and the spring 9 on the core rod 8 is compressed. After the electromagnet coil is powered off, the magnetic force disappears, and the core rod 8 movably arranged in the electromagnet coil hole moves downwards and extends out of the hole under the action of gravity and the restoring force of the spring.

As shown in fig. 1 to 3, the locking hook 5 comprises a first transmission arm 51 and a second transmission arm 52, wherein the first transmission arm 51 is connected to the mandrel 8. A first rotating shaft 10 is arranged in the lower shell 2, and the locking hook 5 is rotatably arranged in the lower shell 2 through the first rotating shaft 10. After an electromagnet coil of the electromagnetic driving mechanism is electrified, under the action of magnetic force, the core rod 8 can reciprocate up and down before and after being electrified, so that the lock hook 5 is driven to rotate around the first rotating shaft 10. Specifically, after an electromagnet coil of the electromagnetic driving mechanism is electrified, under the action of magnetic force, the core rod 8 contracts into an electromagnet coil hole and moves upwards to drive the lock hook 5 to rotate anticlockwise around the first rotating shaft 10, and the spring 9 on the core rod 8 is compressed; after the electromagnet coil is powered off, the core rod 8 moves downwards under the action of the self gravity and the restoring force of the spring and extends out of the electromagnet coil hole, so that the lock hook 5 rotates clockwise around the first rotating shaft 10 under the action of the restoring force of the spring 9.

As shown in fig. 1 to 4, the latch bolt 4 includes a first hooking portion 41, a second hooking portion 42, and a projection 43. Be equipped with second pivot 11 in the casing 2 down, spring bolt 4 rotationally sets up in casing 2 down through second pivot 11, is equipped with spliced pole 12 with second pivot 11 adaptation on the spring bolt 4, and second pivot 11 passes spliced pole 12 and links together spring bolt 4 and casing 2 down. The bolt 4 is sleeved with a torsion spring 13. The torsion spring 13 can keep the bolt 4 always rotating. The torsion spring 13 includes a first bent portion 14 and a second bent portion 15 in the present embodiment. The first bending part 14 is hooked on the connecting column 12 on the bolt 4, and the second bending part 15 is sleeved at the bottom end of the second rotating shaft 11 and fixedly connected with the lower shell 2. When the cabinet door is closed, the torsion spring 13 is compressed. When the cabinet door is opened, the torsion spring 13 provides restoring force to drive the bolt 4 to rotate. The utility model discloses a torsional spring can also reduce the cabinet door when closing and the clearance between the cabinet body.

In the actual use process, if the cabinet door of the storage cabinet needs to be opened, the electromagnet coil is electrified to generate magnetic force. The core rod 8 contracts into the electromagnet coil hole under the action of magnetic force and moves upwards rapidly, the core rod 8 drives the lock hook 5 to rotate anticlockwise around the first rotating shaft 10 while moving, and the second transmission arm 52 of the lock hook 5 is disengaged from the second hook part 42 of the lock tongue 4. When the second driving arm 52 of the locking hook 5 rotates against the edge of the lower housing 2 to stop rotating, the spring 9 on the core rod 8 is compressed. Meanwhile, the latch 4 rotates clockwise around the second rotating shaft 11 by the restoring force of the torsion spring 13, the first hooking portion 41 of the latch 4 is disengaged from the catch 17, and the catch 17 is ejected. Since the latch 17 is connected with the cabinet door, the cabinet door is opened when the latch 17 is ejected. When the latch 4 rotates clockwise around the second rotating shaft 11, the protrusion 43 of the latch 4 presses the swing link 16 of the micro switch 3. When the swing rod 16 of the microswitch 3 is pressed, the microswitch 3 prompts that the cabinet door is in an open state. Then the electromagnet coil is powered off, the magnetic force disappears, at the moment, the core rod 8 moves downwards under the action of the self gravity and the restoring force of the spring 9, and the lock hook 5 rotates clockwise around the first rotating shaft 10 and returns to the original position. If need close the locker door, promote the cabinet door, make hasp 17 promote spring bolt 4, spring bolt 4 is in the compression state again around second axis of rotation 11 anticlockwise rotations, torsional spring 13. During the further rotation of the locking tongue 4, the first hooking part 41 of the locking tongue 4 re-hooks the catch 17, while the second hooking part 42 of the locking tongue 4 abuts against the second actuator arm 52 of the locking hook 5, while the spring 9 is compressed. Finally, the second transmission arm 52 makes the second transmission arm 52 of the lock hook 5 hook and buckle the second buckle part 42 of the lock tongue 4 under the action of the restoring force of the spring 9, at this time, the projection 43 of the lock tongue 4 is disengaged from the swing rod 16 of the microswitch 3, and the microswitch 3 prompts that the cabinet door is in a closed state. The utility model discloses an opening and closing of electromagnetic drive mechanism control cabinet door makes the user can access article, convenient and fast.

The utility model discloses an intelligence lock simple to operate, simple structure, it is with low costs, convenient to use, the manufacturing of being convenient for, the practicality is strong, and the user can access article fast, through micro-gap switch suggestion cabinet door on-off state, makes the locker safe and reliable more.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
