[0025] Embodiment 1:

[0026] See also Figure 1-9 As shown, the utility model relates to a ball buckle type magnetic lock, comprising a magnetic key (not shown), a lock buckle 1 and a lock body 2. The lock body 2 comprises a housing 21, a lock seat 22, a sliding member 23, a spring 24 and a ball 25.

[0027] The housing 21 wraps the lock seat 22. The lock seat 22 is provided with a slide groove 221 and a lock hole 223, the lock hole 223 is connected to the slide groove 221, the slide groove 221 is provided with a space for the sliding member 23 to slide back and forth, the inner wall 222 of the slide groove 221 is a slope surface, the slide groove 221 matches the shape of the sliding member 23, and the cross section is a trapezoid, and the ball 25 can roll between the sliding member 23 and the slope surface.

[0028] The sliding member 23 matches the slide groove 221. The sliding member 23 cooperates with the spring 24 to slide in the slide groove 221. The elastic member is used to reset the sliding member 23. The sliding member 23 has a through hole 231 and at least one ball hole 232. The ball hole 232 is connected to the through hole 231. The ball 25 is arranged in the ball hole 232. When the sliding member 23 is arranged in the slide groove 221, the through hole 231 is aligned with the lock hole 223. The lock buckle 1 includes a lock buckle base 11 and a clamping joint 12. The clamping joint 12 is provided with an annular groove 121 matching the ball 25. The lock buckle 1 is inserted into the through hole 231 through the lock hole 223. When the annular groove 121 is aligned with the ball hole 232, one side of the ball 25 can slide into the annular groove 121 to lock the lock buckle 1, so that the lock buckle 1 cannot be pulled out.

[0029] The sliding member 23 is magnetic, and the magnetic control key can magnetically adsorb the sliding member 23. When the lock buckle 1 is inserted into the through hole 231, one side of the ball 25 will slide into the annular groove 121, and the lock buckle 1 is locked by the ball 25 and cannot be pulled out; when the magnetic control key adsorbs the sliding member 23, the sliding member 23 moves along the inner wall 222 of the slide groove 221 in the direction of the magnetic control key under the influence of the magnetic attraction, and the ball 25 slides out of the annular groove 121 under the thrust of the sliding member 23. At this time, the lock buckle 1 is not locked by the ball 25, so that the lock buckle 1 can be pulled out of the through hole 231 to achieve the unlocking function.

[0030] Furthermore, a spring installation groove 233 is provided at the top of the sliding member 23, and the spring 24 is arranged in the spring installation groove 233, one end of the spring 24 abuts against the bottom of the spring installation groove 233, and the other end abuts against the housing 21. The spring 24 has resilience. In the first embodiment, the spring 24 is a spring. When the magnetic force of the magnetic control key on the sliding member 23 is cancelled, the thrust generated by the resilience of the spring 24 resets the sliding member 23. When the sliding member 23 is reset, the spring 24 abuts against the sliding member 23, providing a supporting force for the sliding member 23, so that the sliding member 23 cannot slide freely inside the sliding groove 221 without the action of external force.

[0031] Furthermore, the cross-section of the ball hole 232 matches the shape of the ball 25, wherein a narrowing portion 2321 is provided at the opening end of the ball hole 232 close to the through hole 231, and the cross-section of the narrowing portion 2321 is smaller than the shape of the ball 25. A portion of the cross-section of the ball 25 can be connected to the annular groove 121 through the narrowing portion 2321, thereby achieving the locking position of the ball 25 for the lock buckle 1 and avoiding the problem of the ball 25 slipping out of the ball hole 232 after the lock buckle 1 is pulled out.

[0032] Embodiment 2:

[0033] The difference between the second embodiment and the first embodiment is that the sliding member 23 cannot be adsorbed by the magnetic control key, and the sliding member 23 is an aluminum alloy, which is light and has low processing cost. The sliding member 23 is iron or a magnet, which is not easy to process and requires a magnet with greater adsorption force. In this embodiment, the ball 25 can be adsorbed by the magnetic control key, that is, the ball 25 is an iron ball or a magnetic ball. When the lock buckle 1 is inserted into the through hole 231, one side of the ball 25 will slide into the annular groove 121. At this time, the lock buckle 1 is blocked by the ball 25 and cannot be pulled out; when the magnetic control key magnetically adsorbs the ball 25, the ball 25 is affected by the magnetic attraction and drives the sliding member 23 to move in the direction of the magnetic control key along the inner wall 222 of the slide groove 221. At this time, because the ball 25 leaves the annular groove 121, the lock buckle 1 is not locked by the ball 25. The lock buckle 1 can be pulled out of the through hole 231 to achieve the unlocking function.

[0034] The utility model relates to a ball buckle type magnetic lock. When locking, the lock buckle 1 is inserted into a through hole 231. When the annular groove 121 is aligned with the ball hole 232, the sliding member 23 is pushed to the bottom of the slide groove 221 by the built-in spring 24, and the ball 25 slides along the slope surface of the inner wall 222 of the slide groove 221 to the narrowing portion 2321. A part of the cross section of the ball 25 can be connected to the annular groove 121 through the narrowing portion 2321. The lock buckle 1 cannot be pulled out of the through hole 231 because it is blocked by the ball 25, thereby realizing the locking function. When unlocking, the utility model controls the sliding member 23 or the ball 25 through the magnetic attraction of the magnetic control key. The sliding member 23 or the ball 25 moves toward the direction of the magnetic control key due to the magnetic attraction. The sliding member 23 drives the ball 25 to leave the annular groove 121, or the ball 25 pushes the sliding member 23 to move away from the annular groove 121. The lock buckle 1 is not restricted by the position of the ball 25 and can be pulled out from the through hole 231 to achieve the unlocking function.

[0035] The utility model does not require screw assembly, has a simple assembly structure, and is convenient for improving production efficiency. When in use, it is only necessary to align the annular groove 121 with the ball hole 232, and push the sliding member 23 to the bottom of the slide groove 221 through the built-in spring 24, and the ball 25 will slide along the slope surface of the inner wall 222 of the slide groove 221 to the narrowing portion 2321 to lock the lock buckle 1. It can be applied to assembly at different angles in actual situations, is simple to operate, and improves flexibility during assembly.

[0036] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
