Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic locks, and in particular to a novel electromagnetic lock. Background Art

[0002] Electromagnetic lock is a device that uses electromagnetic principle to control the opening and closing of door lock. It is mainly composed of two parts: electromagnetic mechanism and lock body. The working principle of electromagnetic lock is to generate magnetic field by energizing the electromagnet coil, so that the magnet block of the electromagnet has magnetism, thereby attracting the lock tongue in the lock body and moving it to achieve the action of unlocking or locking. When the power is off, the electromagnet loses its magnetism, and the lock tongue returns to its original position under the action of the spring, thereby achieving locking.

[0003] The existing electromagnetic lock is limited by its structure, and its lock tongue has a limited travel, which is limited to the use scene. The use is very limited, and the lock tongue can only move in one direction after power on and off, and the locking direction is limited, which cannot meet the use requirements of different scenes. Therefore, a new electromagnetic lock that can change the locking direction and has an adjustable telescopic travel is urgently needed to solve the above problems. Utility Model Content

The locking rod 13 is extended, and a compression spring 14 is sleeved on the area between the sliding plate 15 and the limit plate 10. The front side of the sliding plate 15 is fixedly connected to the lever 6 by a double nut. The front side of the rear cover plate 1 is covered with a front cover plate 3. The left and right sides of the front cover plate 3 and the rear cover plate 1 are respectively equipped with a left cover plate 2 and a right cover plate 4. This design solves the problem that the existing electromagnetic lock 9 is limited by the structure, the travel of the lock tongue is limited, and it is limited to the usage scene. The usage is relatively limited, and the lock tongue can only move in one direction after power on and off, and the locking direction is limited, which cannot meet the usage requirements of different scenarios.

[0030] The left cover plate 2 and the right cover plate 4 are provided with notches on the front side, and the upper part of the front cover plate 3 is recessed inward to form a concave platform, and the concave platform corresponds to the position of the notch. The notch is provided to cooperate with the concave platform to form a concave area inside the device, which provides necessary space for the movement of the locking rod 13, and facilitates the locking of the external device with the locking rod 13. A locking hole 5 is provided on the top of the concave platform, and the position of the locking hole 5 corresponds to the position of the locking rod 13. When locking, the upper end of the locking rod 13 can be inserted into the locking hole 5, and the locking rod 13 is limited by the locking hole 5 to prevent the locking rod 13 from tilting and deviating when being locked, so as to ensure the locking effect of the locking rod 13. A notch is provided on the bottom edge of the concave platform corresponding to the locking rod 13. The notch is provided to facilitate the smooth covering of the locking rod 13 on the rear cover plate 1 when the front cover plate 3 is installed, so as to facilitate the combined installation of the front cover plate 3.

[0031] A slide groove 11 is provided on the front surface of the front cover plate 3, and the lever 6 extends from the slide groove 11. By providing the slide groove 11 on the front cover plate 3, the lever 6 can smoothly move up and down in the slide groove 11, so that the user can easily operate it, which greatly improves the convenience of the user when using the electromagnetic lock 9. At the same time, the slide groove 11 also limits the moving range of the lever 6, provides a stable moving track for the lever 6, prevents the lever 6 from rotating during operation, and ensures the stability and accuracy of the lever 6 during the movement process.

[0032] A rubber sheath is provided on the annular surface of the lever 6, and the rubber sheath can increase the friction between the hand and the lever 6, so that the user can obtain a better grip and control when operating the lever 6, and the operation is more stable and accurate. In a humid or greasy environment, the metal lever 6 may become slippery and difficult to hold. The rubber sheath has good anti-slip performance, and can ensure that the user can operate the lever 6 stably even in adverse environmental conditions.

[0033] The lower side of the sliding plate 15 is fixedly connected to the limit support rod 16 through a double nut, and the limit support rod 16 extends through the limit plate 10.

[0034] The fixing plate 8 is provided with a plurality of straight slots 81, and the electromagnetic lock 9 is fixedly connected to the straight slots 81 by a plurality of bolts. By fixing the electromagnetic lock 9 to the straight slots 81 with a plurality of bolts, the stability of the connection can be ensured, and the design of the straight slots 81 allows the electromagnetic lock 9 to adjust its position within a certain range, which makes the installation process more flexible. The position of the electromagnetic lock 9 can be fine-tuned along the straight slots 81 according to actual conditions.

[0035] A wiring groove is provided inside the right cover plate 4 for wiring connection of the power line of the electromagnetic lock 9.

[0036] The length of the lock rod 13 can be adjusted to be lengthened or shortened according to the use requirements, so as to adjust the locking stroke of the electromagnetic lock 9. The rear cover plate 1 and the front cover plate 3 can be made longer, and the number of internal components can be increased, or multiple groups of devices can be combined and connected, so that multiple groups of devices can be locked at the same time, which is suitable for locking shared devices. In addition, the lock rod 13 is partially higher than the front cover plate 3 in the unlocked state, which is convenient for hanging objects connected with ropes or rings.

[0037] The working principle of this new electromagnetic lock is as follows: connect the electromagnetic lock 9 to an external power source through a power cord, and then scan the QR code through WeChat to control the switch of the electromagnetic lock 9. When the electromagnetic lock 9 is normally powered off, it is in a normally closed state, and its lock tongue extends out and clamps the sliding plate 15. At this time, the sliding plate 15 is located at the uppermost position, and the upper end of the lock rod 13 is clamped into the lock hole 5 to achieve the purpose of locking. At this time, the device is in a locked state; when the electromagnetic lock 9 is powered on, the electromagnetic lock 9 generates a magnetic force to attract the lock tongue to retract. At this time, the sliding plate 15 moves downward under the reverse elastic force of the compression spring 14, driving the lock rod 13 to move downward, and the lock rod 13 is released from the lock hole 5, thereby releasing the locked state, and the device is in an open state. After opening the lock and taking things, manually push the lever 6 upward to drive the sliding plate 15 and the lock rod 13 upward, so that the lock rod 13 is clamped into the lock hole 5. At this time, the lock tongue on the electromagnetic lock 9 limits the sliding plate 15, thereby achieving locking.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
