A locking block 330 and a second spring 340 are provided in the second slot hole 311. The locking block 330 is rotatably connected to the fixing seat 310. The second spring 340 is located between the fixing seat 310 and the locking block 330. The upper end of the connecting block 320 is slidably provided in the second slot hole 311, and the lower end is connected to the ground tongue 220. The connecting block 320 cooperates with the locking block 330 to lock the ground tongue 220 in the locked state; an unlocking component includes a connecting rod 410. The connecting rod 410 cooperates with the locking block 330 to unlock the ground tongue 220. The connecting rod 410 cooperates with the connecting block 320 to unlock the ground tongue 220.

[0036] Combination Figure 4During installation, the bottom buckle seat 230 is hidden and installed at an appropriate position on the floor. A magnetic block 231 is provided in the bottom buckle seat 230. When the glass door 110 is closed, the floor tongue 220 moves to the top of the bottom buckle seat 230. Under the magnetic attraction of the magnetic block 231, the floor tongue 220 moves downward and snaps into the bottom buckle seat 230. The first spring 250 is compressed, and the floor tongue 220 is now locked. When the floor tongue 220 moves downward and snaps into the bottom buckle seat 230, it drives the connecting block 320 to move downward. At this time, the locking block 330 loses the obstruction of the connecting block 320 and slowly rotates under the action of the second spring 340 until it is directly above the connecting block 320 and snaps the connecting block 320. At this time, the floor tongue 220 cannot be pried to unlock it, thereby achieving an anti-prying effect and improving the safety factor. Combined with Figure 5 After the ground tongue 220 is locked, the connecting rod 410 is driven, and the connecting rod 410 cooperates with the locking block 330 to first release the lock of the ground tongue 220, and then the connecting rod 410 cooperates with the connecting block 320 to make the ground tongue 220 separate from the bottom buckle seat 230. The ground tongue 220 is unlocked. At this time, the connecting rod 410 is reset, and the ground tongue 220 remains in an unlocked state away from the bottom buckle seat 230 under the action of the first spring 250. The operation is simple.

[0037] It is understandable that, referring to Figure 2 and Figure 3 The ground lock assembly also includes a long hole connecting rod 240, the lower end of the long hole connecting rod 240 is fixedly connected to the connecting block 320, the upper end of the long hole connecting rod 240 is provided with a long hole, the lower end of the connecting rod 410 is provided with a through hole, and a pin shaft 411 is provided in the through hole, and the pin shaft 411 is penetrated through the long hole.

[0038] Specifically, the long hole connecting rod 240 is connected to the connecting rod 410 through the pin 411. The main function of the long hole is to enable the ground tongue 220 to slide relative to the connecting rod 410, thereby changing the distance between the connecting block 320 and the connecting rod 410. Figure 3 The first spring 250 is sleeved on the ground tongue 220 and is located between the support 210 and the connecting block 320. Under the action of the first spring 250, the long hole connecting rod 240 slides upward relative to the connecting rod 410. At this time, the distance between the connecting block 320 and the connecting rod 410 becomes smaller, and the connecting block 320 holds the locking block 330, so that the locking block 330 is fixed and cannot rotate. Figure 4 When the ground tongue 220 moves to the top of the bottom buckle seat 230, under the magnetic attraction of the magnetic block 231, the ground tongue 220 moves downward and is stuck in the bottom buckle seat 230. At this time, the long hole connecting rod 240 slides downward relative to the connecting rod 410, and the distance between the connecting block 320 and the connecting rod 410 increases. The locking block 330 loses the obstruction of the connecting block 320 and slowly rotates under the action of the second spring 340 until it rotates to the top of the connecting block 320 and locks the connecting block 320.

[0039] It is understandable that, referring to Figure 2 and Figure 3 The invention also includes a lock seat 510 and a lock box 520 . The lock seat 510 is fixedly connected to the lock box 520 .
