[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0017] Please refer to Figs. 1 to 3The utility model provides a technical scheme: a kind of magnetic attraction quick release buckle, including shell 1, fastener 2 and hanging rope 3, fastener 2 and shell 1 are split type, the inside of shell 1 is divided into installation area and dismounting area, and hanging rope 3 is connected with fastener 2;Fastener 2 is movably arranged in dismounting area, and the outer edge part of fastener 2 is provided with protrusion 4;Magnetic attraction assembly, magnetic attraction assembly is respectively installed at the inside of shell 1 and the end of fastener 2;Limiting component, limiting component is arranged in the installation area of the inside of shell 1, and extend to the top end of shell 1, wherein the limiting component can abut on the side wall of protrusion 4, for limiting the disengagement direction movement of fastener 2 in shell 1.

[0018] It should be noted that during installation, first, fastener 2 is placed in the dismounting area of shell 1, the magnetic force of magnetic attraction assembly is used to make inner magnetic block 9 and outer magnetic block 8 in the state of mutual adhesion, at this time, fastener 2 is tightly adhered with the bottom cover 102 of shell 1. Then the operator pushes fastener 2 away from the installation area, inner magnetic block 9 and outer magnetic block 8 gradually separate, in the process of pushing, fastener 2 extrudes U-shaped limiting part 6, so that U-shaped limiting part 6 deforms, under the continuous pushing, the protrusion 4 of fastener 2 is clamped with the dismounting area, and the locking state is realized. When it is needed to dismount shell 1 and fastener 2, the operator needs to press the limiting component downward, so that the limiting component moves downward, and the restriction of U-shaped limiting part 6 in the limiting component on protrusion 4 is released. The fastener 2 is rotated until outer magnetic block 8 and inner magnetic block 9 adhere to each other, the protrusion 4 is in the clamped state with the dismounting area, then the hanging rope 3 is pulled, the fastener 2 is separated from the shell 1, and the dismounting process is completed.

[0019] In some examples, shell 1 is composed of outer frame 101, bottom cover 102 and face cover 103, notch 104 is arranged on face cover 103, which facilitates the installation and dismounting of fastener 2.

[0020] In some examples, a pressing hole is formed in face cover 103, and the limiting component includes spring 5, U-shaped limiting part 6 and button 7, one end of spring 5 is fixedly arranged on bottom cover 102 and located in the installation area of shell 1, U-shaped limiting part 6 is sleeved on button 7 and located between bottom cover 102 and face cover 103, U-shaped limiting part 6 abuts against protrusion 4, and button 7 penetrates through the pressing hole and is fixedly arranged on the other end of spring 5.

[0021] It should be noted that when the fastener 2 needs to be disassembled, the operator presses the button 7 downward through the pressing hole, so that the spring 5 is compressed, and at the same time drives the U-shaped limiting piece 6 to move downward, thereby releasing the restriction of the U-shaped limiting piece 6 on the protrusion 4 of the fastener 2. Then, the fastener 2 is pulled to make the outer magnetic block 8 and the inner magnetic block 9 adhere to each other, and the state of the protrusion 4 being clamped with the disassembly area is released. Finally, the fastener 2 is separated from the shell 1 by pulling the hanging rope 3, and the disassembly process is completed. In the whole process, the pressing hole on the face cover 103 allows the operator to press the button 7, and the cooperation of the spring 5, the U-shaped limiting piece 6 and the button 7 ensures the quick disassembly and locking of the fastener 2.

[0022] In some examples, the magnetic attraction assembly includes an outer magnetic block 8 and an inner magnetic block 9, the outer magnetic block 8 is installed on the bottom cover 102, and the inner magnetic block 9 is embedded on the inner side of the fastener 2 and can be attracted to the outer magnetic block 8. When the fastener 2 is installed and disassembled, the mutual attraction of the inner magnetic block 9 and the outer magnetic block 8 can quickly arrange the fastener 2 on the shell 1 and achieve the effect of quick positioning, and then the fastener 2 is quickly separated or quickly locked with the shell 1 by pulling the pull rope or pushing the fastener 2.

[0023] In some examples, the disassembly area is provided with two first limiting surfaces 10 and two second limiting surfaces 11, and the locking state is that the outer edge part of the protrusion 4 is in contact with the two first limiting surfaces 10, and the outer edge part of the fastener 2 is in contact with the two second limiting surfaces 11. The arrangement of the first limiting surface 10 and the second limiting surface 11 in the disassembly area ensures the stable locking of the fastener 2, and when the fastener 2 is in the locking state, the fastener 2 and the shell 1 are more stable, preventing the fastener 2 from shaking.

[0024] In some examples, the locking state is that the U-shaped limiting piece 6 is in abutment with the protrusion 4. The protrusion 4 of the fastener 2 is in contact with the two first limiting surfaces 10 of the disassembly area, and at the same time, the outer edge part of the fastener 2 is in contact with the two second limiting surfaces 11, forming a locking state. In this locking state, the U-shaped limiting piece 6 is in abutment with the protrusion 4 of the fastener 2, ensuring that the fastener 2 will not accidentally come off. The abutment of the U-shaped limiting piece 6 and the protrusion 4 realizes the stable locking of the fastener 2.
