[0031] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0032] Reference Figures 1 to 5 As a kind of magnetic attraction prevents the quick-release buckle of detaching provided in the embodiments of the present application, including female buckle 1 and male buckle 2, female buckle 1 has accommodating cavity 11, accommodating cavity 11 side is set to opening 111, the two sides of accommodating cavity 11 close to opening 111 are respectively equipped with first intercepting wall 12 and second intercepting wall 13, the bottom of accommodating cavity 11 is equipped with first suction member 14, female buckle 1 is equipped with abutting push piece 15, abutting push piece 15 pushes second intercepting wall 13 sliding and extends into accommodating cavity 11;Male buckle 2 has clamping lug 21, the two sides of clamping lug 21 are respectively equipped with first clamping part 211 and second clamping part 212, clamping lug 21 is equipped with second suction member 22.

[0033] When the male buckle 2 and the female buckle 1 are connected, the clamping protrusion 21 enters the accommodating cavity 11 from the opening 111, the second suction member 22 and the first suction member 14 are mutually adsorbed to adsorb the clamping protrusion 21 into the accommodating cavity 11, and the abutting pushing piece 15 pushes the clamping protrusion 21 to move to abut the first clamping portion 211 against the first intercepting wall 12 and abut the second clamping portion 212 against the second intercepting wall 13. The clamping locking of the clamping protrusion 21 is realized. In the application, through the mutual adsorption of the first suction member 14 and the second suction member 22 and the pushing action of the abutting pushing piece 15, the male buckle 2 and the female buckle 1 can be self-installed in place without pressing, avoiding the risk of installation out of place.

[0034] Specifically, the abutting pushing piece 15 is a spring, the female buckle 1 is provided with a mounting cavity 16, the spring and the second intercepting wall 13 are arranged in the mounting cavity 16, the spring abuts against the second intercepting wall 13 and can push the second intercepting wall 13, so that the second intercepting wall 13 partially extends into the accommodating cavity 11 to realize the clamping limiting of the second clamping portion 212. In the embodiment, the second intercepting wall 13 is provided with an extrusion surface 131, the extrusion surface 131 is a bevel or an arc surface, and the clamping protrusion 21 can extrude the extrusion surface 131 during installation into the accommodating cavity 11 to retract the second intercepting wall 13 in the mounting cavity 16 to make room, so as to facilitate the magnetic adsorption of the clamping protrusion 21 into the accommodating cavity 11. The female buckle 1 is also provided with a cover plate 17, and the cover plate 17 covers the mounting cavity 16 to limit the spring and the second intercepting wall 13 in the mounting cavity 16.

[0035] In other embodiments, the abutting pushing piece 15 can also adopt a pushing air cylinder, which can be controlled by a circuit module.

[0036] Further, the female buckle 1 is provided with an unlocking button 18, the unlocking button 18 protrudes from the mounting cavity 16, and the unlocking button 18 drives the second intercepting wall 13 to slide and retract in the mounting cavity 16.

[0037] Specifically, the mounting cavity 16 is provided with a room-providing groove 161 on the top wall, the unlocking button 18 is columnar, one end of the unlocking button 18 protrudes from the room-providing groove 161, and the other end is fixedly connected with the second intercepting wall 13. The room-providing groove 161 is arranged along the sliding direction of the second intercepting wall 13, and is a strip-shaped groove. The unlocking button 18 passes through the room-providing groove 161 and protrudes from the room-providing groove 161, and is also limited in the room-providing groove 161 and slides along the extension direction of the room-providing groove 161. When unlocking is needed, the unlocking button 18 is pushed by the finger, and the unlocking button 18 drives the second intercepting wall 13 to slide and retract in the mounting cavity 16. At this time, the male buckle 2 can be quickly pulled to separate the male buckle 2 and the female buckle 1.

[0038] In the embodiment, the unlocking button 18 is protruded from the mounting cavity 16 to facilitate the user to operate it with the hand. Meanwhile, a clearance groove 161 is formed in the top wall of the mounting cavity 16 to provide a space for the unlocking button 18 to move. In other embodiments, if the position of the unlocking button 18 is changed, the clearance groove 161 can be optionally provided accordingly.

[0039] Further, the female buckle 1 is provided with a first assembly groove 19 in which the first suction member 14 is fixed, and the male buckle 2 is provided with a second assembly groove 23 in which the second suction member 22 is fixed. The first assembly groove 19 and the second assembly groove 23 facilitate the installation of the first suction member 14 and the second suction member 22.

[0040] Specifically, the first suction member 14 and the second suction member 22 are both columnar magnets, and the opposite faces of the two are magnetically opposite. The first suction member 14 is fixed in the first assembly groove 19 by gluing, and the second suction member 22 is fixed in the second assembly groove 23 by gluing. The two columnar magnets have similar volume and size, and the end faces of the two columnar magnets are opposite to each other when they are attracted, and the axes of the two columnar magnets are aligned and coincided, which can achieve the effect of alignment and limiting. Therefore, it can be ensured that the clamping protrusion 21 can be attracted to the specified position every time when it enters the accommodating cavity 11, so that the connection stability of the male buckle 2 and the female buckle 1 is guaranteed.

[0041] In other embodiments, one of the first suction member 14 and the second suction member 22 is a magnet, and the other is an iron block. The two are fixed in the first assembly groove 19 and the second assembly groove 23 by gluing, respectively, and the shape of the magnet and the iron block is not limited. The clamping protrusion 21 can be attached to the accommodating cavity 11 through the mutual attraction of the magnet and the iron block. However, compared with the above embodiment, the first suction member 14 and the second suction member 22 in the present embodiment do not have the alignment effect, and the clamping protrusion 21 is mainly pushed to the position by the abutting pushing member 15.

[0042] In the present embodiment, when the male buckle 2 and the female buckle 1 are connected, the clamping protrusion 21 enters the accommodating cavity 11 from the opening 111, the second suction member 22 and the first suction member 14 are mutually attracted to make the clamping protrusion 21 attracted to the accommodating cavity 11, the abutting pushing member 15 pushes the clamping protrusion 21 to move to make the first clamping part 211 abut against the first intercepting wall 12 and the second clamping part 212 abut against the second intercepting wall 13, thereby achieving the clamping locking of the clamping protrusion 21. In the present application, through the mutual attraction of the first suction member 14 and the second suction member 22 and the pushing action of the abutting pushing member 15, the male buckle 2 and the female buckle 1 can be installed in place without pressing, thereby avoiding the risk of not being installed in place and falling out.

[0043] The embodiments of the present embodiment are the preferred embodiments of the present utility model, not limited to the protection scope of the present utility model, so: all equivalent changes made according to the structure, shape and principle of the present utility model should be covered in the protection scope of the present utility model.
