Description

Technical Field

[0001] This utility model relates to the field of electric suction lock technology, and in particular to a closed locking type electric suction lock. Background Technology

[0002] An electromagnetic lock, also known as an electromagnetic lock or electromagnetic attraction lock, is a device that uses electromagnetic principles to lock and unlock. It mainly consists of an electromagnet and an iron armature. When the electromagnet is energized, it generates a strong magnetic force that firmly attracts the armature, thus locking the lock. When the power is off, the magnetic force disappears, and the armature returns to its original position under the action of a spring or other external force, opening the lock. This type of lock is characterized by its relatively simple structure, easy installation, and flexible control. It is commonly found in access control systems, cabinet locks, toolbox locks, and some automated equipment, and is particularly suitable for applications requiring rapid and frequent opening and closing while remaining open during power outages.

[0003] Some electric door locks commonly found on the market require users to apply considerable physical force to close the door or cabinet door securely. This design can be inconvenient for elderly people or children with limited strength, as they may struggle to close the door completely, resulting in the lock not closing tightly and posing a safety hazard. Utility Model Content

[0004] One objective of this invention is to provide a closed-locking electric suction lock. This invention addresses the problem mentioned in the background that traditional electric suction locks can cause inconvenience for elderly people or children with relatively insufficient strength, making it difficult for them to fully close the door, resulting in the lock not closing tightly and posing a safety hazard.

[0005] A closed-locking electric suction lock according to an embodiment of the present utility model includes a base plate, a drive mechanism, an emergency unlocking mechanism, and a locking mechanism. The drive mechanism includes a first drive motor, an unlocking block, a latch, and a first latch. The first latch is fixedly installed on one side of the latch. The latch and the unlocking block are both rotatably installed on one side surface of the base plate. The locking mechanism includes a second latch and a second drive motor. The second latch is driven and installed at the output end of the second drive motor through a transmission shaft. A through hole is opened on the surface of the second latch, and a photoelectric transmitter and a photoelectric receiver are fixedly installed on the inner surface of the through hole, respectively.

[0006] Preferably, a first fixing block and a second fixing block are respectively fixedly installed on one side surface of the base plate, and a screw is rotatably installed on the inner side of the first fixing block and the second fixing block, and the screw is driven and installed at the output end of the first drive motor.

[0007] Preferably, the screw has a sliding block threaded onto its surface, and a connecting rod is fixedly installed on the lower side of one side of the sliding block.

[0008] Preferably, a first fixing rod is fixedly installed on one side surface of the unlocking block, a first rotating rod is rotatably installed on one side surface of the base plate, a first spring is installed between the first rotating rod and the unlocking block, and a first stop bar is fixedly installed on one side of the unlocking block.

[0009] Preferably, a third rotating rod is rotatably mounted on one side surface of the base plate, a second rotating rod is rotatably mounted on one side surface of the locking tongue, and a second spring is installed between the second rotating rod and the third rotating rod.

[0010] Preferably, a second stop bar is fixedly installed on one side surface of the locking tongue.

[0011] Preferably, the emergency unlocking mechanism includes a fixed pulley and a squeezing block. A pull rope is fixedly installed on one side of the squeezing block. The pull rope is in close contact with the side surface of the fixed pulley. The fixed pulley is rotatably installed on the lower part of one side surface of the base plate.

[0012] Preferably, a second fixing rod is also fixedly installed on the lower part of one side surface of the base plate, and an unlocking spring is installed between one side of the second fixing rod and one side of the pressing block.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a locking mechanism. When the electric magnetic lock is closed, the baffle rotates to one side of the locking mechanism. The drive mechanism drives the latch to rotate, causing the first latch to engage with the inner side of the second latch. The first latch blocks the signal between the photoelectric transmitter and the photoelectric receiver on the inner side of the second latch. The internal microcontroller controls the second drive motor of the locking mechanism to drive the second latch to rotate clockwise by a certain angle via the transmission shaft. The clockwise rotation of the second latch pulls the first latch and the entire baffle inward for automatic locking, eliminating the need for manual pressing. This improves closing efficiency and convenience, making it especially convenient for the elderly and children, and ensuring more reliable locking.

[0015] This utility model features an emergency unlocking mechanism. In an emergency, the pull cord of the emergency unlocking mechanism can be pulled downwards, thereby squeezing the unlocking block to the left, causing the unlocking block to rotate clockwise. After the unlocking block is no longer obstructed, the lock tongue will be rotated towards the inside of the base plate by the reset force of the second spring, causing the first latch to rotate upwards from the inside of the second latch, thus achieving emergency unlocking. The simple pull cord operation quickly releases the locked state, improving the convenience of use and the flexibility to deal with emergencies. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figure 1-3A closed-locking electric suction lock includes a base plate 1, a drive mechanism 2, an emergency unlocking mechanism 3, and a locking mechanism 4. The drive mechanism 2 includes a first drive motor 203, an unlocking block 206, a locking tongue 211, and a first latch 216. The first latch 216 is fixedly installed on one side of the locking tongue 211. The locking tongue 211 and the unlocking block 206 are both rotatably installed on one side surface of the base plate 1. The locking mechanism 4 includes a second latch 403 and a second drive motor 401. The second latch 403 is driven and installed at the output end of the second drive motor 401 via a drive shaft 402. A through hole is opened on the surface of the second latch 403. A photoelectric transmitter 404 and a photoelectric receiver 405 are fixedly installed on the inner surface of the through hole, respectively. Through the locking mechanism 4, the electric suction lock is activated. When the lock is closed, the baffle rotates to one side of the locking mechanism 4. The drive mechanism 2 drives the latch 211 to rotate and makes the first latch 216 lock the inside of the second latch 403. The first latch 216 blocks the signal between the photoelectric transmitter 404 and the photoelectric receiver 405 inside the second latch 403. The internal microcontroller controls the second drive motor 401 of the locking mechanism 4 to drive the second latch 403 to rotate clockwise by a certain angle through the transmission shaft 402. The clockwise rotation of the second latch 403 pulls the first latch 216 and the entire baffle to automatically lock inward. There is no need for manual pressing to lock, which improves the closing efficiency and convenience, especially for the elderly and children, and ensures more reliable locking.

[0023] Example 1: A first fixing block 201 and a second fixing block 202 are respectively fixedly installed on one side surface of the base plate 1. A screw 204 is rotatably installed on the inner side of the first fixing block 201 and the second fixing block 202. The screw 204 is driven and installed at the output end of the first drive motor 203. A sliding block is threadedly connected to the surface of the screw 204. A connecting rod 205 is fixedly installed on the lower side of one side of the sliding block. A first fixing rod 207 is fixedly installed on one side surface of the unlocking block 206. A first rotating rod 208 is rotatably installed on one side surface of the base plate 1. A first spring 209 is installed between the first rotating rod 208 and the unlocking block 206. A first stop rod 210 is fixedly installed on one side of the unlocking block 206. A third rotating rod 213 is also rotatably installed on one side surface of the base plate 1. A second rotating rod 212 is rotatably installed on one side surface of the locking tongue 211. A second spring 214 is installed between the second rotating rod 212 and the third rotating rod 213. A second stop rod 215 is fixedly installed on one side surface of the locking tongue 211.

[0024] Example 2: The emergency unlocking mechanism 3 includes a fixed pulley 301 and a compression block 303. A pull rope 302 is fixedly installed on one side of the compression block 303, and the pull rope 302 is tightly attached to the side surface of the fixed pulley 301. The fixed pulley 301 is rotatably mounted on the lower part of one side surface of the base plate 1. A second fixing rod 305 is also fixedly installed on the lower part of one side surface of the base plate 1. An unlocking spring 304 is installed between one side of the second fixing rod 305 and one side of the compression block 303. With the emergency unlocking mechanism 3, in case of an emergency, the spring 304 can be released by tightening the compression block 303. When the pull rope 302 of the emergency unlocking mechanism 3 is pulled downward, the pressing block 303 presses the unlocking block 206 to the left, causing the unlocking block 206 to rotate clockwise. After the unlocking block 206 is no longer obstructed, the locking tongue 211 will be rotated towards the inside of the base plate 1 by the reset force of the second spring 214, causing the first latch 216 to rotate upward from the inside of the second latch 403, thus achieving emergency unlocking. The locking state can be quickly released by simply pulling the rope 302, which improves the convenience of use and the flexibility to deal with emergencies.

[0025] When locking is required, the first drive motor 203 is activated, and its output drives the screw 204 to rotate. The rotation of the screw 204 drives the sliding block to slide to the left, and the connecting rod 205 on the sliding block moves to the left accordingly, no longer exerting force on the first fixed rod 207 on the unlocking block 206. At this time, the return force of the first spring 209 acts on the unlocking block 206, causing it to rotate counterclockwise. During the counterclockwise rotation of the unlocking block 206, its first stop rod 210 will press the second stop rod 215 on the latch 211, thereby pushing the latch 211 to rotate clockwise, causing the latch 211 to rotate out from the inside of the base plate 1. After the latch 211 rotates into place, its first latch 216 is locked into the inside of the second latch 403. When the baffle rotates to the locking mechanism 4 side, the first latch 216 locks into the second latch 403, blocking the signal between the photoelectric transmitter 404 and the photoelectric receiver 405 inside the second latch 403. This signal change is detected by the internal microcontroller, which then controls the second drive motor 401 to start. The second drive motor 401 drives the second latch 403 to rotate clockwise by a certain angle via the transmission shaft 402. The rotation of the second latch 403 pulls the first latch 216 and the entire baffle to move inward, achieving automatic locking without manual pressing. During unlocking, the first drive motor 203 rotates in the opposite direction, driving the screw 204 to rotate in the opposite direction, and the sliding block slides to the right. The connecting rod 205 moves to the right and presses the first fixed rod 207, causing the unlocking block 206 to rotate clockwise. After the unlocking block 206 rotates clockwise, it no longer blocks the latch 211. At this time, the return force of the second spring 214 acts on the latch 211, causing it to rotate counterclockwise together with the first latch 216. The first latch 216 rotates out from inside the second latch 403, completing the unlocking. In case of emergency, the emergency unlocking mechanism 3 can be activated by pulling the cord 302. The cord 302 moves the compression block 303, which in turn compresses the unlocking block 206, causing it to move to the left and rotate clockwise. After the unlocking block 206 rotates clockwise, it loses its obstruction of the latch 211. The restoring force of the second spring 214 causes the latch 211 and the first latch 216 to rotate counterclockwise. The first latch 216 then rotates out from inside the second latch 403, thus achieving emergency unlocking.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
