The top of the seat body 3 is provided with a U-shaped slide 30 that matches the diameter gap of the cylindrical part 111. The top of the second outer positioning plate 21 is provided with an arc-shaped limit portion 211. The inner side surface of the lock plate 4 is provided with an arc-shaped notch 40 that matches the arc-shaped limit portion 211. The top edge of the arc-shaped notch 40 is provided with an arc-shaped locking portion 41 that matches the annular groove 111a. The bottom of the seat body 3 is provided with a transverse guide groove 31 connected to the U-shaped slide 30. The transverse guide groove 31 is matched with the lock plate 4. The two lock plates 4 are movably arranged on both sides of the transverse guide groove 31. The spring 5 abuts between one end face of the transverse guide groove 31 and the outer side surface of the lock plate 4. The arc-shaped notch 40 abuts on the outer wall of the arc-shaped limit portion 211. The first magnet 12 and the second magnet 22 are opposite in poles.

[0024] The working principle is as follows: in order to install the upper buckle assembly 1 and the lower seat assembly 2 on the flap and the main body of the handbag respectively, it is necessary to pre-open mounting holes in the flap and the main body of the handbag. When installing the upper buckle assembly 1, the first inner positioning plate 10 is located on the outer side of the flap, and the first outer positioning plate 110 is located on the inner side of the flap. The first inner positioning plate 10 and the first outer positioning plate 110 are assembled through the mounting holes in the flap, thereby installing the upper buckle assembly 1 on the flap. When installing the lower seat assembly 2, the second inner positioning plate 20 is located on the inner side of the main body, and the second outer positioning plate 21 is located on the outer side of the main body. The second inner positioning plate 20 and the second outer positioning plate 21 are assembled through the mounting holes in the main body, thereby installing the lower seat assembly 2 on the main body. The positions of the upper buckle assembly 1 and the lower seat assembly 2 correspond to each other. When the flip cover needs to be closed, the flip cover is closed on the outside of the main body, and the cylindrical portion 111 will abut against the edges of the arcuate locking portions 41 of the locking plates 4 on both sides. The locking plates 4 will compress the springs 5 ​​and retreat along the transverse guide grooves 31. When the arcuate locking portions 41 align with the annular retaining grooves 111a, the locking plates 4 will return to their original position under the elastic force of the springs 5, and the arcuate locking portions 41 will be locked on the annular retaining grooves 111a, thereby longitudinally locking the cylindrical portion 111. At the same time, the first magnet 12 and the second magnet 22 will be attracted together, preventing the cylindrical portion 111 from moving and preventing the flip cover from opening automatically. When the flip cover needs to be opened, the flip cover is pulled downward to allow the cylindrical portion 111 to move outward along the U-shaped slide 30. The annular retaining grooves 111a will separate from the arcuate locking portions 41, separating the first magnet 12 and the second magnet 22, and the flip cover can be opened. The structure is simple, can effectively prevent the flip cover from opening automatically, has a good fixing effect, is relatively convenient to use, and is easy to operate.

[0025] Based on the above embodiment, the bottom outer edge of the cylindrical portion 111 is provided with a guiding bevel 111b, and the top inner edge of the arcuate locking portion 41 is provided with a guiding arcuate surface 410. When the flip cover is closed on the outer side of the main body, the guiding bevel 111b of the cylindrical portion 111 will abut against the guiding arcuate surface 410, which can more effectively drive the locking plates 4 on both sides to open, reducing wear on the arcuate locking portion 41 and the cylindrical portion 111.

[0026] Based on the above embodiment, two limit plates 32 are arranged side by side on both end surfaces of the transverse guide groove 31. The interval between the two limit plates 32 matches the diameter of the spring 5. The spring 5 is arranged between the two limit plates 32. A limit column 42 is provided on the outer surface of the lock plate 4. One end of the spring 5 is sleeved on the limit column 42, which can limit the spring 5, avoid the spring 5 from deflecting, and ensure that the lock plate 4 opens and closes stably.

[0027] Based on the above embodiment, the bottom of the first inner positioning plate 10 is provided with an externally threaded connection portion 100, and the upper end of the first receiving hole 110a is provided with an internally threaded hole 110b that matches the externally threaded connection portion 100. The externally threaded connection portion 100 is connected to the internally threaded hole 110b. When installing the bead assembly 1, the first inner positioning plate 10 is located on the outer surface of the flip cover, and the first outer positioning plate 110 is located on the inner side of the flip cover. The externally threaded connection portion 100 is then connected to the internally threaded hole 110b, thereby installing the bead assembly 1 on the flip cover.

[0028] Based on the above embodiment, the bottom of the second outer positioning plate 21 is provided with a plurality of connecting posts 212. The second inner positioning plate 20 is provided with countersunk holes 200 corresponding to the connecting posts 212. The bottom of the connecting posts 212 is provided with screw holes, and the countersunk holes 200 and the screw holes are connected by screws. When installing the lower seat assembly 2, the second inner positioning plate 20 is located on the inner side of the main body, and the second outer positioning plate 21 is located on the outer side of the main body. The mounting holes provided in the main body correspond to the screw holes. The screws are then connected between the countersunk holes 200 and the screw holes, thereby installing the lower seat assembly 2 on the main body.

[0029] Based on the above embodiment, the bottom of the base body 3 is provided with an interlocking groove 33 connected to the transverse guide groove 31, and the shape of the second outer positioning plate 21 matches the shape of the interlocking groove 33. The second outer positioning plate 21 is arranged in the interlocking groove 33 and is connected to the base body 3 by screws, which can reduce the volume of the lock and improve the compactness and stability of the structure.

[0030] Based on the above embodiment, a first through hole 111c communicating with the first accommodating hole 110a is provided through the bottom end of the cylindrical portion 111, and a second through hole 213 communicating with the second accommodating hole 210 is provided through the top of the second outer positioning plate 21, so that the first magnet 12 and the second magnet 22 in the first accommodating hole 110a and the second accommodating hole 210 can be conveniently poked out through the first through hole 111c and the second through hole 213, thereby facilitating the replacement of the magnets.

[0031] Based on the above embodiment, a limiting cone 214 located on the inner side of the arc-shaped limiting portion 211 is provided on the top of the second outer positioning plate 21. When the arc-shaped locking portion 41 is engaged with the annular groove 111a, the bottom end of the cylindrical portion 111 is adjacent to the top of the limiting cone 214, thereby preventing the cylindrical portion 111 from vibrating under force and colliding with the arc-shaped locking portion 41, thereby avoiding noise.

[0032] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
