Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4, an anti-theft short-beam mechanical padlock, comprising a lock body 1, a rectangular groove 2, a strip groove 3 and an unlocking groove 4 are arranged in the lock body 1, a lock ring body 5 is slidably installed in the strip groove 3, both sides of the short end of the bottom of the lock ring body 5 are provided with a card slot 6, an unlocking piece 7 is slidably installed in the unlocking groove 4, a limiting mechanism 8 is arranged in the rectangular groove 2 for the card slot 6 at the short end of the lock ring body 5 to be clamped, the limiting mechanism 8 comprises a transverse spring 81, a movable slide 82, a circular groove 83, a card block 84 and a connecting groove 85, a transverse spring 81 is clamped on one side of the inner wall of the rectangular groove 2, one end of the transverse spring 81 is clamped on the circular groove 83 on one side of the movable slide 82, and both sides of the short end of the bottom of the lock ring body 5 are provided with a card block 84 for clamping the card slot 6, the bottoms of the two card blocks 84 are integrally processed on the top of the movable slide 82, and the rectangular groove 2 is connected to the unlocking groove 4 through the connecting groove 85.
[0023] Specifically, the unlocking member 7 includes a cylinder 71, a magnetic block 72 and a partition ring 73. The cylinder 71 is slidably mounted inside the unlocking groove 4, and the magnetic block 72 and the partition ring 73 are fixedly mounted on the top of the cylinder 71. The movable slide 82 is set as a metal slide, and the magnetic block 72 is located on one side of the connecting groove 85.
[0024] In this embodiment, the cylinder 71 is inserted into the unlocking groove 4, and the magnetic block 72 at the upper end of the cylinder 71 is put into the top of the unlocking groove 4 and is located on one side of the connecting groove 85. The movable slide 82 is attracted by the suction force of the magnetic block 72, and the transverse spring 81 is stretched. The movable slide 82 drives the top clamping block 84 to slide under the suction force of the magnetic block 72, so that both sliders are not engaged with the clamping groove 6. Under the action of the vertical spring 11, the lock ring body 5 is ejected to achieve unlocking. The suction force of the magnetic block 72 needs to be set to a fixed value. A magnet with too large a suction force or too small a suction force cannot be unlocked. At the same time, a partition ring body 73 is provided to isolate and protect the other side of the magnetic block 72.
[0025] Specifically, a limiting groove 9 coaxially arranged with the circular groove 83 is provided inside the movable slide 82, and a limiting rod 10 is slidably installed inside the limiting groove 9, and one end of the limiting rod 10 is fixedly installed on the inner wall of the rectangular groove 2. With the above design, during the movement of the movable slide 82, the internal limiting groove 9 slides on the surface of the limiting rod 10, which has the function of limiting the horizontal direction of the sliding of the movable seat.
[0026] Specifically, the long end of the bottom of the lock ring body 5 is slidably installed inside the strip groove 3, and the bottom of the inner wall of the strip groove 3 is clamped with a movable pin 12 through a vertical spring 11, and the top of the movable pin 12 fits with the long end of the bottom of the lock ring body 5. With the above design, when the short end of the bottom of the lock ring body 5 is not limited by the limiting mechanism 8, the vertical spring 11 will push the movable pin 12 upward, and the movable pin 12 pushes the top lock ring body 5 to pop out.
[0027] Specifically, a limit ring 13 is fixedly installed at the long end of the bottom of the lock ring 5, and a limit chamber 14 for the limit ring 13 to slide is provided inside the lock body 1. With the above design, when the lock ring 5 moves, it will drive the limit ring 13 to slide in the limit chamber 14, preventing the lock ring 5 from falling off the lock body 1.
[0028] Specifically, the bottoms of the strip groove 3 and the rectangular groove 2 are both connected with drainage holes 15, and the bottoms of the two drainage holes 15 pass through the bottom of the lock body 1. In the above design, the drainage holes 15 are arranged at the strip groove 3 and the rectangular groove 2 to prevent the water vapor in the rectangular groove 2 and the strip groove 3 from being unable to be discharged in time.
[0029] Specifically, sealing sleeves 16 are fixedly installed on both sides of the lock ring body 5, an adjustment plate 17 is rotatably installed at the bottom of the lock body 1, and a sealing cover 18 that matches the unlocking groove 4 is integrally processed on the top of the adjustment plate 17. In the above design, the sealing sleeve 16 is arranged on the surface of the lock ring body 5, thereby reducing the waterproof protection of the connection between the lock body 1 and the lock ring body 5. At the same time, an adjustment plate 17 is rotatably arranged at the bottom of the lock body 1, and a sealing cover 18 is arranged on the top of the adjustment plate 17, and the adjustment plate 17 and the sealing cover 18 are made of rubber.
[0030] Working principle: this device inserts the cylinder 71 into the unlocking slot 4, and the magnetic block 72 at the upper end of the cylinder 71 is put into the top of the unlocking slot 4 and is located on one side of the connecting slot 85. The movable slide 82 is attracted by the suction force of the magnetic block 72, and the transverse spring 81 is stretched. The movable slide 82 drives the top clamping block 84 to slide under the suction force of the magnetic block 72, so that both sliders are not engaged with the clamping slot 6. Under the action of the vertical spring 11, the lock ring body 5 is ejected to achieve unlocking. The suction force of the magnetic block 72 needs to be set to a fixed value. Magnets with too large suction force or too small suction force cannot be unlocked. At the same time, a partition ring body 73 is provided to isolate and protect the other side of the magnetic block 72.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
