In this embodiment, can inhale the knot through built-in magnetism and realize one step light suitcase protecgulum that opens and shuts fast, promote user experience, reduce the user operation degree of difficulty, save user operation time, guarantee that box 210 outward appearance is succinct.

Specifically, the arrangement of the magnetic lock includes, but is not limited to, the following technical solutions:

example 1 (shown in FIGS. 1 and 2)

In this embodiment, preferably, the locking portion 113 has a slide groove 116 formed therein, and the slider 130 is disposed in the slide groove 116 and is capable of sliding left and right in the slide groove 116.

In this embodiment, the slider 130 is configured to slide left and right instead of up and down, so that the overall height of the magnetic lock can be reduced, and thus the magnetic lock does not protrude out of the luggage case 210 when the magnetic lock is applied to products such as a luggage case, thereby further improving the overall appearance of the luggage case.

In the above embodiment, preferably, the slider 130 includes a main body 132 and a control portion 133 disposed on the main body 132, a top surface of the control portion 133 is an inclined surface, the control lever 115 abuts against the inclined surface, and a return spring (not shown) is disposed between the control portion 133 and a side wall of the connecting portion 112.

In this embodiment, after the button 114 is pressed, the control rod 115 can continuously push against the inclined surface to drive the slider 130 to slide rightward, and automatically slide leftward under the action of the return spring, so as to unlock the magnetic lock and automatically return the slider 130, and prepare for the next locking.

In the above embodiment, preferably, magnets (not shown) are disposed in the sliding block 130, the locking tongue 121 and the lock block 120, and an attractive force between the locking tongue 121 and the magnets in the sliding block 130 is greater than an attractive force between the locking tongue 121 and the magnets in the lock block 120.

In this embodiment, through set up magnet in spring bolt 121, locking piece 120 and slider 130, utilize the heteropolar attracting or homopolar repulsion of magnet for magnetism is inhaled the lock and can be easily opened and shut fast, promotes user experience, reduces the user operation degree of difficulty, saves user operating time.

In the above embodiment, the lock catches 122 are preferably disposed on two sides of the latch tongue 121, and two lock catches 122 are disposed on each side, and one of the lock catches 122 on the same side is spaced from the lock block 120 by a smaller distance than the other lock catch 122.

In this embodiment, the lock catches 122 on the lock tongue 121 are arranged two on each side, so that the magnetic attraction lock is more reliable in locking; and the distance between the lock catch 122 and the lock block 120 on the same side is different, and the lock hook 131 can automatically disengage from the lock catch 122 in the process that the lock frame drives the lock block 120 to slide, so that the resistance during unlocking is further reduced.

The working principle of the magnetic suction lock related to the embodiment 1 of the invention is as follows:

when the magnetic lock is in a locked state, the bolt 121 on the lock block 120 extends into the lock part 113, the sliding block 130 in the lock part 113 can lock the bolt 121, at this time, the N pole of the magnet in the sliding block 130 and the S pole of the magnet in the bolt 121 attract each other in opposite polarities (or vice versa), and the S pole of the magnet in the sliding block 130 and the N pole of the magnet in the bolt 121 attract each other in opposite polarities, so that the magnetic lock is more stable in the locked state; when the magnetic lock is unlocked, the button 114 is pressed, the button 114 controls the slider 130 to slide leftwards (or rightwards) through the control rod 115, the S pole (or the N pole) of the magnet in the slider 130 is far away from the N pole (or the S pole) of the magnet in the bolt 121 and is close to the S pole (or the N pole) of the magnet in the bolt 121 in the sliding process, the magnet is arranged in the lock block 120 in the same way by utilizing the principle that the same poles of the magnet repel each other, and the bolt 121 is automatically ejected out of the locking part 113 by utilizing the suction force between the lock block 120 and the magnet in the bolt 121, so that the automatic unlocking of the magnetic lock is; when locking is performed again, when the locking block 120 is close to the locking part 113, because the suction force between the sliding block 130 and the locking tongue 121 is greater than the suction force between the locking tongue 121 and the locking block 120, the locking tongue 121 can automatically slide into the locking part 113 and then is clamped with the sliding block 130 again, so that the magnetic suction lock is automatically locked.

Example 2 (as shown in FIGS. 3 to 5)

In this embodiment, it is preferable that the latch bolt 121 is a cylinder, and the latch bolt 121 includes a connection section 123 connected to the lock block 120 and a catching portion 124 connected to the connection section 123, and a diameter of the connection section 123 is smaller than a diameter of the catching portion 124.

In the above embodiment, preferably, the sliding block 130 is a U-shaped structure having an opening, the locking hook 131 is an arc-shaped groove opened on two opposite side walls of the U-shaped structure, and the clamping portion 124 can be clamped on the arc-shaped groove.

In the above embodiment, it is preferable that the lever 115 includes a link 117 and a lock lever 118 which are integrally formed, the link 117 is connected to the button 114, and the lock lever 118 is connected to the slider 130.
