Meanwhile, the positioning groove 15 moves to the guide portion 241, and since the guide portion 241 is inclined upward, the positioning groove 15 is guided by the guide portion 241 to be supported upward, thereby guiding the first connecting plate 11 and the second connecting plate 21 to be completely separated.

In this embodiment, referring to fig. 7, the locking plate 3 includes a bending portion 32 and a horizontal portion 33, two connecting pieces are folded at one side of the horizontal portion 33 close to the bending portion 32, the connecting pieces are hinged to the second connecting plate 21, and the limiting grooves 31 are disposed at two sides of the horizontal portion 33 and correspond to the limiting posts 14. The first connecting plate 11 is provided with a yielding hole 16 corresponding to the bending part 32, and when the bending part 32 rotates to abut against the side wall of the yielding hole 16, the first buckle 1 is separated from the second buckle 2. In the scheme, the horizontal portion 33 is provided with a connecting hole 34, the connecting hole 34 is used for arranging a handle belt (not shown in the figure), and a user can directly pull the handle belt to turn over the locking sheet 3 in use, so that the use is convenient. The handle strip can be made of flexible materials such as cloth strips, binding ropes and the like.

Further, a first yielding groove 25 for moving the bent portion 32 is formed at one end of the second connecting plate 21 close to the bent portion 32, so that the bent portion 32 is not interfered by the second connecting plate 21 and the first connecting plate 11 when rotating. The inner walls of the two sides of the first abdicating groove 25 simultaneously play a role in guiding and limiting the bending part 32.

In this embodiment, second connecting plate 21 both sides be provided with spacing post 14 with the second groove 26 of stepping down that spacing groove 31 corresponds, second groove 26 length of stepping down is greater than spacing groove 31 length, second groove 26 one side of stepping down with spacing groove 31 one side flushes, and the installation direction is removed to when flushing the end from the one side of keeping away from flush end, and it is fixed to accomplish the buckle. When the locking device is used, the limiting column 14 simultaneously limits the second connecting plate 21 and the locking piece 3, and structural stability is provided. Preferably, one side wall of the second abdicating groove 26, which is substantially flush with the flat end, is provided with an inclined portion for assisting the limiting column 14 to enter the second abdicating groove 26.

In this embodiment, two sides of the first connecting plate 11 are provided with limiting walls 17 for limiting the second connecting plate 21, and the limiting columns 14 are respectively arranged on the side walls of the two opposite sides of the limiting walls 17.

The use process comprises the following steps: when the buckle is buckled, the second buckle 2 is placed above the first buckle 1, under the action of power provided by the magnetic attraction force, the second buckle moves to the magnetic attraction piece 4 to be completely aligned and attracted along the guide block 13, the guide groove 23 and the limiting walls 17 on the two sides, at the moment, the clamping block 22 is completely clamped with the clamping groove 12, the guide block 13 is embedded in the guide groove 12, the locking piece 3 is simultaneously attracted to the second connecting plate 21 by the magnetic attraction piece 4, and the limiting column 14 is clamped and limited by the limiting groove 31;

when opening, pull up stay 3, make kink 32 with first groove 25 butt of stepping down continues the application of force, can make the complete perk of second connecting plate 21, spacing post 14 with locating piece 13 breaks away from along the inclined plane roll-off respectively, accomplishes first buckle 1 with the dismantlement of second buckle 2.

In the scheme, through the matching of the clamping block 22 and the clamping groove 12, the magnetic part 4 is attracted to limit the movement of the clamping structure in the vertical direction; the buckle structure is enabled to move in the horizontal plugging direction for limiting through the matching of the limiting column 14 and the limiting groove 31 (if the buckle structure moves due to the impact in the direction, the fixture block 22 and the clamp groove 12 are easily separated, and the magnetic part 4 deviates and the magnetic force is reduced, so that the buckle is loosened and separated); the horizontal movement is limited by the limiting wall 17, the guide block 13 and the like. When the locking sheet 3 is not actuated, the first buckle 1 and the second buckle 2 are completely fixed and cannot be separated due to external collision.

This scheme sets up spacing post 14 and spacing groove 31 in lateral wall department, compares in setting up in the middle part and has avoided the destruction to the whole form of stay 3, makes 3 each positions of stay have all kept better structural strength, have slowed down in long-term the use deformation that stay 3 produced, and spacing groove 31 and the second groove 26 of stepping down through both sides make the block and break away from the process all simple more fast, improve the use impression.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
