Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock technology, and more specifically to a magnetic locking structure lock. Background Technology
[0002] Industrial cabinets contain various electrical components and are equipped with locks on the doors to allow the doors to open and close relative to the cabinet body. Industrial cabinets mostly use traditional mechanical locks. Existing mechanical locks unlock the lock cylinder by inserting a key into the lock cylinder, which pushes the pins or springs inside the lock to a specific height. Subsequently, a torsional force can be applied to the key to rotate the lock cylinder and ultimately open and close the cabinet door. However, there are drawbacks. Repeated friction between the pins or springs and the key will accelerate the wear rate, causing the key to be unable to push the pins or springs to a specific height and thus failing to achieve the purpose of unlocking. Furthermore, the key will develop gaps due to wear, and during the process of inserting or removing the key into the lock cylinder, the key may come into contact with individual pins or springs, hindering the movement of the key. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a structural lock that reduces wear and can be used smoothly.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a magnetic locking structure lock, comprising a lock shell, a lock cylinder rotatably connected within the lock shell, a bolt positioned at the end of the lock cylinder, and a key insertable into the lock cylinder; further comprising a magnetic repulsion assembly and a magnetic attraction assembly distributed along the length of the lock cylinder; the magnetic repulsion assembly comprising a weak repulsion magnet and a strong repulsion magnet, and the magnetic attraction assembly comprising a weak attraction magnet and a strong attraction magnet; the lock shell is provided with a magnetic repulsion hole for the weak repulsion magnet to engage and a strong repulsion magnet to be accommodated, and a magnetic repulsion hole for the weak attraction magnet to engage. The lock cylinder has a magnetic suction hole that allows a strong magnet to be inserted. The peripheral wall of the lock cylinder is provided with a slot that communicates with the magnetic repulsion hole and allows the strong magnet to enter, and a slot that communicates with the magnetic suction hole and allows the strong magnet to be accommodated. The length of the strong magnet is greater than the depth of the slot. The key is provided with a strong repulsion magnetic ring and a strong attraction magnetic ring that correspond to the slot and the slot, respectively. By inserting the key into the lock cylinder, the strong repulsion magnetic ring pushes the strong magnet completely into the magnetic repulsion hole and the strong attraction magnetic ring pulls the strong magnet completely into the slot. The lock cylinder can rotate relative to the lock shell under the drive of the key.
[0005] As a further improvement of this utility model, the lock cylinder is provided with a rotating groove extending circumferentially along the lock cylinder on its peripheral wall, and the lock shell is provided with a rotation-limiting post that extends into the rotating groove at one end.
[0006] As a further improvement of this utility model, a positioning ball is elastically connected inside the lock housing and contacts the top of the lock cylinder peripheral wall. Two positioning grooves are provided on the lock cylinder peripheral wall, which are distributed along the circumference of the lock cylinder and are used for partial engagement of the positioning ball. The arc length between the two positioning grooves is the same as the arc length between the two ends of the rotating groove.
[0007] As a further improvement of this utility model, the rotation limiting column, positioning ball, magnetic repulsion component and magnetic attraction component are all located in the same vertical plane.
[0008] The beneficial effects of this utility model are as follows: by inserting the key into the lock cylinder, the strong repulsion magnetic ring pushes the strong repulsion magnet completely into the magnetic repulsion hole and the strong attraction magnetic ring pulls the strong attraction magnet completely into the card hole. The lock cylinder can rotate relative to the lock shell under the drive of the key. Compared with the existing technology, this design can effectively avoid the phenomenon of key wear and tear, ensure the structural stability of the key, and prevent mutual friction between the magnet and the magnetic ring, thereby improving the smoothness of the key entering and exiting the lock cylinder.

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.
[0012] Reference Figs. 1-3 As shown, a magnetic locking structure lock of this embodiment includes a lock shell 1, a lock cylinder 2 rotatably connected to the lock shell 1, a bolt 3 positioned at the end of the lock cylinder 2, and a key 4 that can be inserted into the lock cylinder 2; Based on the aforementioned prior art, the lock cylinder 2 also includes a magnetic repulsion assembly 5 and a magnetic attraction assembly 6 distributed along its length. The magnetic repulsion assembly 5 includes a weak repulsion magnet 51 and a strong repulsion magnet 52, with the strong repulsion magnet 52 having a stronger magnetism than the weak repulsion magnet 51. The magnetic attraction assembly 6 includes a weak attraction magnet 61 and a strong attraction magnet 62, with the weak attraction magnet 61 having a weaker magnetism than the strong attraction magnet 62. The lock housing 1 is machined with a magnetic repulsion hole 11 and a magnetic attraction hole 12 extending radially along the lock housing 1 and located along its length. Both the magnetic repulsion hole 11 and the magnetic attraction hole 12 are countersunk. The smaller end of the hole is connected to the inner cavity of the lock housing 1. A groove 21 and a hole 22 are machined on the peripheral wall of the lock cylinder 2, extending radially along its length. The length of the strong repulsive magnet 52 is greater than the depth of the groove 21, and the length of the strong attracting magnet 62 is less than the length of the hole 22. During assembly, the lock cylinder 2 is rotated and connected to the lock housing 1, with the groove 21 and hole 22 corresponding to the magnetic repulsion hole 11 and magnetic attracting hole 12, respectively. Then, the strong repulsive magnet 52 is inserted into the magnetic repulsion hole 11, and the strong repulsive magnet 52 moves along the magnetic repulsion hole 11... Move the magnet to slot 21. The two ends of the strong repulsive magnet 52 are located in the magnetic repulsion hole 11 and slot 21 respectively. Then, press the weak repulsive magnet 51 against the larger inner diameter end of the magnetic repulsion hole 11. The weak repulsive magnet 51 is then fixed relative to the lock housing 1. The opposing ends of the strong repulsive magnet 52 and the weak repulsive magnet 51 have the same magnetic poles. Then, the weak attracting magnet 61 and the strong attracting magnet 62 with their different magnetic poles facing each other are brought together. Then, the strong attracting magnet 62 and the weak attracting magnet 61 are sequentially inserted into the magnetic attracting hole 12. The weak attracting magnet 61 is aligned with the larger inner diameter end of the magnetic attracting hole 12. One end is interference-fitted, and the two ends of the strong magnet 62 are located in the magnetic groove 12 and the card hole 22 respectively. A strong repulsive magnetic ring 41 and a strong attracting magnetic ring 42 are fixedly sleeved at the end of the key 4 that is used to insert into the lock cylinder 2. A magnetic block is integrally formed on the peripheral wall of both the strong repulsive magnetic ring 41 and the strong attracting magnetic ring 42. A side opening for the magnetic block to enter is processed at the lock cylinder port. The magnetic pole of the strong repulsive magnet 52 that extends into the card groove 21 is the same as the magnetic pole of the magnetic block on the strong repulsive magnetic ring 41. The magnetic pole of the strong attracting magnet 62 that extends into the card hole 22 is different from the magnetic pole of the magnetic block on the strong attracting magnetic ring 42. Initially, the weak repulsive magnet 51 and the strong repulsive magnet 52 repel each other. The two ends of the strong repulsive magnet 52 are respectively positioned in the magnetic repulsion groove 11 and the slot 21. The weak attracting magnet 61 and the strong attracting magnet 62 attract each other and adhere. The two ends of the strong attracting magnet 62 are respectively positioned in the magnetic attraction groove 12 and the slot 22. The lock cylinder 2 cannot rotate relative to the lock shell 1. During the process of unlocking the lock cylinder 2 from the lock shell 1, the key 4 is inserted into the lock cylinder 2. The strong repulsive magnetic ring 41 and the strong attracting magnetic ring 42 correspond to the slot 21 and the slot 22 respectively. Because the repulsive force generated by the strong repulsive magnetic ring 41 and the strong repulsive magnet 52 is greater than the repulsive force generated by the strong repulsive magnet 52 and the weak repulsive magnet 51, the strong repulsive magnet 52 is pushed towards the weak repulsive magnet 51. The strong repulsive magnet 52 completely exits the slot 21 and enters the magnetic repulsion groove 11. The attraction between the magnetic ring 42 and the strong magnet 62 is greater than the attraction between the strong magnet 62 and the weak magnet 61. Therefore, the strong magnet 62 is attracted into the slot 22 and disengages from the magnetic groove 12, which can drive the key 4 to rotate. The lock cylinder 2 can rotate relative to the lock shell 1. When the magnetic block of the strong repulsive magnetic ring 41 deviates to one side, the strong repulsive magnet 52 will change back to its initial state. One end of the strong repulsive magnet 52 touches the peripheral wall of the lock cylinder 2 and slides relative to it. The strong magnet 62 rotates synchronously with the lock cylinder 2. During the process of restoring the lock cylinder 2 and the lock shell 1, the key 4 is driven to reverse to the inserted state. Then the key 4 is pulled out. The strong repulsive magnet 52 enters the slot 21 under the push of the weak repulsive magnet 51 and returns to its initial state. The strong magnet 62 enters the magnetic groove 12 under the attraction of the weak magnet 61 and returns to its initial state. Compared with existing technologies, this design can effectively avoid the wear and tear of key 4, ensure the structural stability of key 4, and prevent mutual friction between the magnet and the magnetic ring, thereby improving the smoothness of key 4 entering and exiting lock cylinder 2.
[0013] As one specific implementation method of the improvement, refer to Fig. 3 As shown, a rotating groove 23 extending circumferentially along the lock cylinder 2 is machined on the peripheral wall of the lock cylinder 2, and a through hole extending radially along the lock shell 1 is machined on the lock shell 1. A rotation limiting post 13 is engaged from the outside to the inside in the through hole. The length of the rotation limiting post 13 is greater than the length of the through hole and one end extends into the rotating groove 23. When the key 4 drives the lock cylinder 2 to rotate relative to the lock shell 1, when the end of the limiting post 13 touches one end of the rotating groove 23, the lock cylinder 2 cannot continue to rotate relative to the lock shell 1. This design can provide the lock cylinder 2 with an accurate rotation angle and improve the accuracy of the bolt 4 rotation, so as to facilitate smooth opening or locking of the door.
[0014] As one specific implementation method of the improvement, refer to Fig. 3As shown, two positioning grooves 24 distributed circumferentially on the peripheral wall of the lock cylinder 2 are machined. The arc length between the two positioning grooves 24 is the same as the arc length between the two ends of the rotating groove 23. A positioning through hole extending radially on the lock shell 1 is machined. Then, the positioning ball 14 is inserted into the positioning through hole. The positioning ball 14 moves along the positioning through hole until it touches the top of the peripheral wall of the lock cylinder 2. By rotating the lock cylinder 2, the positioning groove 24 corresponds to the positioning through hole, and the positioning ball 14 partially enters the positioning groove 24. Subsequently, a spring is inserted into the positioning through hole, and the spring is limited between the plug and the positioning through hole by using an interference fit between the plug and the positioning through hole. In the initial state, the limiting post The positioning ball 14 engages with one end of the rotating groove 24 and the positioning pin 13 contacts the rotating groove 23. During the rotation of the key 4 by external force, the positioning ball 14 slides relative to the positioning groove 24 and is pushed into the positioning through hole. The spring is compressed, and then the positioning ball 14 slides relative to the peripheral wall of the lock cylinder 2 until the limiting pin 13 contacts the other end of the rotating groove 23. The lock cylinder 2 stops rotating relative to the lock shell 1, the spring recovers its deformation and pushes the positioning ball 14 into another positioning groove 24. When no one applies force to the key 4, the positioning ball 14 and the positioning groove 24 cooperate with each other to assist the stability of the state of the lock cylinder 2 relative to the lock shell 1 and prevent the lock cylinder 2 from rotating arbitrarily relative to the lock shell 1.
[0015] As one specific implementation method of the improvement, refer to Figs. 1-3 As shown, the rotation limiting post 13, the positioning ball 14, the magnetic repulsion component 5, and the magnetic attraction component 6 are all located in the same vertical plane. During the assembly process, the required holes can be opened sequentially along the length of the lock case 1 so that the rotation limiting post 13, the positioning ball 14, the magnetic repulsion component 5, and the magnetic attraction component 6 can be installed in the corresponding holes in the same direction. This design can improve the hole opening efficiency and assembly efficiency compared to the design of staggering each hole along the circumference of the lock case 1.
