[0035] As Figures 1-8 shown, a rotating side-insert magnetic snap fastener of the present utility model includes a male snap 1 and a female snap 2;

[0036] An insertion blind hole 3 is formed on the top side of the female snap 2, a slot 4 is formed on the right side of the female snap 2, the inner end of the slot 4 communicates with the insertion blind hole 3, and an avoidance groove 5 is formed at the right end of the rear side of the female snap 2, and the avoidance groove 5 communicates with the slot 4;

[0037] A connection block 6 is formed at the upper end of the left side of the male snap 1, a plug rod 7 is formed at the left end of the connection block 6, an L-shaped structure is formed between the plug rod 7 and the connection block 6, the connection block 6 is installed in the slot 4 and the avoidance groove 5 with a clearance fit, the plug rod 7 is rotationally fitted and inserted into the insertion blind hole 3, and the bottom end of the plug rod 7 is magnetically fitted in the insertion blind hole 3;

[0038] The principle is that the male snap 1 is inserted and cooperated with the female snap 2 by a side-insertion method. After the connection is completed, the plug rod 7 will be stuck in the insertion blind hole 3 and connected by magnetic attraction. After the male snap 1 and the female snap 2 are respectively connected to the straps, the mutual buckling between the male snap 1 and the female snap 2 can withstand a greater pulling force without being broken. At the same time, the setting of the avoidance groove 5 allows the connection block 6 to flip a certain angle, so that the plug rod 7 can rotate a certain angle in the insertion blind hole 3, enabling the male snap 1 and the female snap 2 to better fit on the straps, and is applicable to items such as clothing, suspenders, packing belts, suitcases, pet leashes, etc., and is more comfortable to use.

The first magnetic member 8 and the second magnetic member 9 are magnetically coupled to each other; the magnetic members are installed by embedding, so that the magnetic force will not affect the male buckle 1 and the female buckle 2, and this magnetic force is only used to magnetically attract the bottom end of the insertion rod 7 into the insertion blind hole 3.

[0040] Furthermore: The first magnetic member 8 and the second magnetic member 9 are respectively any one of a permanent magnet and a magnetic conductive block; appropriate materials can be selected as the magnetic members to make the two in a state where they can magnetically attract each other, ensuring the stability of the connection between the male buckle 1 and the female buckle 2.

[0041] Furthermore: A straight surface 10 is formed on the left side of the male buckle 1, and the left side of the straight surface 10 abuts against the front edge position on the right side of the female buckle 2. At this time, the rear side surface of the male buckle 1 and the rear side surface of the female buckle 2 are on the same plane; when the male buckle 1 and the female buckle 2 are flush with each other, the straight surface 10 can be used for rotational limiting. The male buckle 1 and the female buckle 2 can only be bent inward by a certain angle, having a more fitting effect and being more comfortable to use.

[0042] Furthermore: A first rounded corner 11 is formed at the rear edge on the left side of the male buckle 1, and a second rounded corner 12 is formed at the rear edge on the right side of the female buckle 2; the rounded corners can be used to achieve stable cooperation between the male buckle 1 and the female buckle 2 without affecting the bending and rotation between the male buckle 1 and the female buckle 2.

[0043] Furthermore: The height of the male buckle 1 is the same as the height of the female buckle 2.

[0044] Furthermore: Two first wire grooves 13 are formed on the left side of the female buckle 2, and the two first wire grooves 13 are arranged in parallel. Two second wire grooves 14 are formed on the right side of the male buckle 1, and the two second wire grooves 14 are arranged in parallel; the wire grooves can be used to install straps, and the two straps are buckled through the male buckle 1 and the female buckle 2, which is convenient for actual use.

[0045] Furthermore: A first thickened edge 15 is formed on the front side of the female buckle 2 near the male buckle 1, and a second thickened edge 16 is formed on the front side of the male buckle 1 near the female buckle 2; the strength of the male buckle 1 and the female buckle 2 can be effectively enhanced, and the service life is improved.
