[0021] As shown in FIGS. 1 to 3, a bag having a structure for quick attachment according to the present invention includes a first housing 11, a second housing 12, a first fastener 41, and a connection component. The butting ends are formed on the first housing 11 and the second housing 12, and a first dimension is limited by the perimeter of the butting ends. The connection component includes a first fixed frame 21, a second fixed frame 22, a first connection ring 31, a second connection ring 32, and a curved connection part 5.

[0022] The first fixed frame 21 is connected to the first housing 11, the second fixed frame 22 is connected to the second housing 12. Both the first fixed frame 21 and the second fixed frame 22 are integrally injection-molded and adapted to the dimensions of the first housing 11 and the second housing 12. The first fixed frame 21 is thermally pressure-bonded to the first housing 11 by a first engagement groove 23, and the second fixed frame 22 is thermally pressure-bonded to the butting end 13 of the second housing 12 by a second engagement groove 24. The first dimension limited by the perimeter of the butting end 13 is equal to the second dimension limited by the perimeter of the first fixed frame 21.

[0023] In other unshown embodiments, a protrusion is formed at the butting end of the first fixed frame 21, the first engagement groove 23 has a recess, and when the first fixed frame 21 is connected to the first housing 11, the protrusion and the recess serve to support positioning and attachment. The protrusions may be arranged along the entire circumferential direction of the fixed frame, may be arranged at intervals along the fixed frame, and the protrusions and the recesses are arranged to correspond to each other along the circumferential direction. In other unshown embodiments, even when a recess is provided on the first fixed frame 21 and a protrusion is provided in the first engagement groove 23, it can serve to support attachment and positioning.

[0024] As shown in FIGS. 3 to 4, the first fastener 41 includes two bands, and the two bands are respectively connected to the first fixed frame 21 and the second fixed frame 22 by the first connection ring 31 and the second connection ring 32, whereby they are fixed to the first housing 11 and the second housing 12. Specifically, a second engagement groove 24 is formed in the first fixed frame 21, a first extending end portion 311 is formed in the first connection ring 31, the first extending end portion 311 is fixed and adhered to one band, and the first fastener 41 is similarly connected to the second fixed frame 22 by the first extending end portion 312 of the second connection ring 32 on the other band. In other embodiments not shown, the band and the first extending end portion 311 may be fixed and connected by sewing.

[0025] Regarding the installation of the first extending end portion 311 and the second engagement groove 24, the first extending end portion 311 of the first connection ring 31 is limited to an L shape with a predetermined inclination, and the second engagement groove 24 is a corresponding clip groove. First, the band is fixed and connected to the first extending end portion 311 of the first connection ring 31, and then the first connection ring 31 is fixed to the second engagement groove 24 by adhesion. The first extending end portion 311 of the second connection ring 32 and the second engagement groove 24 of the second fixed frame 22 are similarly connected.

[0026] Regarding the installation of the first connection ring and the second connection ring, in other embodiments not shown, the first extending end portion is formed in a V shape with an inclination and a band nip is formed. After the first band is fixed to the band nip of the first extending end portion, the first connection ring and the second connection ring are respectively fixed to the second engagement groove by adhesion.

[0027] The bag further includes a liner. Regarding the connection of the liner (not shown), as shown in FIG. 3, the bag further includes a third connection ring 33 and a fourth connection ring 34. The two liners adapted to the first housing and the second housing are respectively fixed and connected to the third engagement groove 25 in the first fixed frame and the second fixed frame by the third connection ring 33 and the fourth connection ring 34. Specifically, a second extending end portion 331 is formed on the third connection ring 33, and the liner and the second extending end portion 331 are connected by sewing. The third connection ring 33 is adhered to the third engagement groove 25. The arrangement and mounting method of the fourth connection ring 34 are the same as those of the third connection ring 33.

[0028] Regarding the connection method between the liner and the second extending end portion, in other embodiments not shown, methods such as adhesion and thermocompression bonding may be adopted.

[0029] As shown in FIG. 4, regarding the installation of the curved connection portion 5, the curved connection portion 5 has a predetermined length and adopts an integral bendable soft adhesive material, and includes two accommodating portions 51 and two position restricting and buffering portions 52 that are symmetrically installed along the axis. The accommodating portion 51 matches the groove side portion of the first engagement groove 23 of the first fixed frame 21 and the second fixed frame 22, and the position restricting and buffering portion 52 is fixedly connected to the first housing 11 and the second housing 12. The position restricting and buffering portion 52 is located at both ends of the curved connection portion 5 and can limit the opening angle of the first housing 11 with respect to the second housing 12.

[0030] The curved connection portion connects the first housing 11 and the second housing 12, opens while hinge-connecting the housings, and the joint formed by the first fixed frame 21 and the second fixed frame 22 is located below and covered by the curved connection portion 5. In other embodiments not shown, the curved connection portion may be installed as two upper and lower parts and realize the function of being bendable by hinge connection, and hard or soft position restricting and buffering portions may still be independently installed on each part.

[0031] The engaging portions 26 are respectively installed on the first fixed frame 21 and the second fixed frame 22. The engaging portion 26 has an engaging positioning end. When the first housing 11 closes to the second housing 12, the engaging positioning ends engage with each other to avoid the displacement of the first housing 11 and the second housing 12 and play a supporting role. The upper edge portion of the engaging portion 26 is formed by the extension of the groove edge portion of the second engaging groove 24, and the lower edge portion of the engaging portion 26 is formed by the extension of the groove edge portion of the third engaging groove 25. The engaging positioning ends of the first fixed frame 21 and the second fixed frame 22 are L-shaped, and ribs are further installed between the respective second engaging grooves and the third engaging grooves of the first fixed frame 21 and the second fixed frame 22, ensuring the strength and reducing the usage materials.

[0032] As described above, the specific embodiments of the present invention have been described. Based on the described content, those skilled in the art can make various changes and modifications without departing from the technical idea of the present invention.
