Electronic ring latch

Abstract

The invention discloses an electronic ring latch, relating to an improvement on the structure of an electronic ring latch. The invention provides an electronic ring latch, which has a simple structure and high safety. The electronic ring latch comprises a lock body, a lock core and a U-shaped latch hook. The structural key points are that: the top end of the lock core is connected with the inner wall of the lock body through a torsion spring; one side of the top end of the lock core is provided with a ball groove corresponding to a ball; the lock core is provided with a magnetic block unit corresponding to a coil; the magnetic block unit comprises a fixed magnetic block and a sliding magnetic block; the fixed magnetic block is embedded into one side of the lock core; the sliding magnetic block is arranged in a magnetic block groove on the other side of the lock core; magnetic poles of the fixed magnetic block and the sliding magnetic block are arranged oppositely; a clamping groove isformed in the lock body corresponding to the sliding magnetic block; and the depth H of the magnetic block groove, the length L of the sliding magnetic block and the depth h of the clamping groove decrease in sequence.

Description

technical field [0001] The invention relates to the improvement of the electronic padlock structure. Background technique [0002] The use of mechanical locks has a long history. Because the key can be copied by a simple profiling machine, and the repetition rate is high, its safety is difficult to guarantee. [0003] Although the existing electronic locks have solved the problem of being easy to imitate, the structure of the lock cylinder is usually relatively complicated. The electronic lock with such a complex structure has a relatively large volume; it cannot be applied to padlocks. [0004] Existing electronic padlock is as the patent No. 200820065111.0 name is " electric motor electric control lock " patent, and this patent makes padlock work by motor, gearbox and crank-link mechanism, and structure is complicated, and failure rate is high; It is used in places suspended outside, so it is not only vulnerable to vibration but also vulnerable to damage; for institutions...

AI Technical Summary

Problems solved by technology

[0002] The use of mechanical locks has a long history, because the key can be copied by a simple profiling machine, and the repetition rate is high, so its safety is difficult to guarantee

[0003] Although the existing electronic locks solve the problem of easy imitation, the structure of the lock cylinder is usually relatively complicated. This kind of electronic lock with complex structure is relatively large in size; it cannot be applied to padlocks

[0004] Existing electronic padlock is as the patent No. 200820065111.0 name is " electric motor electric control lock " patent, and this patent makes padlock work by motor, gearbox and crank-link mechanism, and structure is complicated, and failure rate is high; It is used in places suspended outside, so it is not only vulnerable to vibration but also vulnerable to damage; for institutions with complex structures, such vibration and damage are fatal; so this type of product has low service life, high failure rate, and poor safety. problems, making it impossible to popularize and promote

[0005] In addition, the patent No. 200620089280.9 is a patent named "An Electronic Lock Cylinder". This patent discloses the method of using fixed magnetic beads to attract sliding magnetic beads, so that the lock cylinder and the lock cylinder dial are not restricted, and the lock cylinder is opposite to each other. The dial of the lock cylinder can be rotated freely, so the lock body cannot be opened; when the electronic key is used, the lock cylinder verifies the key ID through the electronic control board, and then connects the key with the coil in the lock cylinder, and the key supplies power to the coil; the coil generates a magnetic field Force the sliding magnetic ball to leave the groove of the lock cylinder, and fix the position between the lock cylinder and the lock cylinder dial, so that the lock can be opened by rotating the lock cylinder to control the lock cylinder dial. Small, but it is not suitable for use in padlocks; because the lock cylinder can rotate freely in the lock body, when it is applied to the padlock, the stability is poor, and the vibration of the padlock is easy to cause damage to the lock cylinder
