Description

Buckle is inhaled to magnetism Technical Field The utility model relates to a magnetic attraction buckle, and belongs to the technical field of magnetic attraction fixation. Background In modern technology and daily life, there is an increasing demand for connecting and securing devices. Traditional connection modes such as screws, buckles, glue and the like, although meeting the connection requirements to a certain extent, have some defects in certain specific occasions. For example, screw connections require tools, are cumbersome to operate, snap connections can be easily damaged during frequent disassembly, and glue connections can be inconvenient to disassemble and reuse. With the popularity of electronic devices and lightweight products, there is a growing demand for portability, ease of use, and aesthetics of the connection devices. The magnetic attraction technology has been widely used in many fields because of its advantages of no need of tools, simple operation, repeated use, etc. However, the existing magnetic connection device still has some defects in structural design and functionality, such as insufficient magnetic strength, poor connection stability, inconvenient installation and disassembly and the like. Disclosure of utility model Based on the above, the utility model provides the magnetic attraction buckle with the double fixing structure, which can enhance the stability and reliability of buckle connection. The technical scheme of the utility model is that the magnetic attraction buckle comprises: The magnetic attraction butt joint piece A comprises a base, a magnetic chuck A, a clamping block and a magnetic attraction piece A, wherein the magnetic chuck A is disc-shaped and is arranged on the base, the clamping block is arranged on the circumferential direction of the magnetic chuck A, and the magnetic attraction piece A is arranged on the magnetic chuck A; The magnetic attraction butt joint piece B comprises a magnetic chuck B, a clamping groove and a magnetic attraction piece B, wherein the magnetic chuck B is disc-shaped and matched with the magnetic chuck A, the clamping groove is annularly arranged at the edge of the disc-shaped end face of the magnetic chuck B, a notch corresponding to the clamping block is arranged on the clamping groove, the magnetic attraction piece B is arranged on the magnetic chuck B, and the magnetic attraction piece B can be adsorbed by the magnetic attraction piece A. In one example, two clamping blocks are symmetrically arranged on two sides of the magnetic chuck A, and two corresponding notches are symmetrically arranged on two sides of the clamping groove. In one example, the magnetic chuck A and the clamping block are provided with a mounting hole A, the magnetic attraction piece A is mounted in the mounting hole A, the disk-shaped end face of the magnetic chuck B is provided with a mounting hole B, and the magnetic attraction piece B is mounted in the mounting hole B. In one example, the mounting hole A comprises a strip-shaped hole A and a round hole A, the strip-shaped hole A is arranged on the magnetic chuck A, the round hole A is arranged on the clamping block, and the mounting hole B comprises a strip-shaped hole B and a round hole B which are formed on the magnetic chuck B. In one example, the clamping groove comprises a vertical portion and a top blocking portion, the vertical portion is arranged along the edge of the disc-shaped end face of the magnetic chuck B, and the top blocking portion is arranged at the top of the vertical portion and extends inwards for a preset distance to form a containing space capable of containing the clamping block. In one example, the magnetic chuck B is provided with a fixing hole. The magnetic attraction type double-fixing structure has the advantages that when the magnetic attraction type double-fixing structure is used, the clamping blocks on the magnetic attraction butt joint piece A are embedded into the gaps of the magnetic attraction butt joint piece B and rotate clockwise for a certain angle, mechanical locking is formed at the moment, and the magnetic attraction piece A and the magnetic attraction piece B of the two parts are adsorbed together by continuing to rotate, so that the magnetic attraction type double-fixing structure is formed. If the clamping blocks need to be separated, the clamping blocks rotate anticlockwise until the clamping blocks reappear at the notch, and the separation can be realized. Compared with the prior art, the utility model enhances the stability and reliability of connection and prevents accidental falling through a double fixing mode of magnetic attraction and mechanical locking. The magnetic attraction buckle can be widely applied to various fields of electronic equipment, household articles, toys and the like, and has wide market application prospect.
