DETAILED DESCRIPTION

[0028] The present invention is further described with reference to the following examples.

[0029] For a specific embodiment of the quick assembly and disassembly structure of the present invention, please see Figure 1 and Figure 2 , including a latch, an upper base 1, a buckle 2, a lower base 4, and a buckle assembly. It should be noted that the socket assembly is a conventional three-prong buckle on the market, which mainly consists of a male buckle 52 and a female buckle 51, and mainly uses elastic arms and a clamping hole to achieve the buckle 2's mating.

[0030] In this embodiment, one end of the latch extends horizontally, and the other end extends vertically. To facilitate manufacture and use, the latch comprises an upper latch 31, a lower latch 33, and a connector 32. In other embodiments, the upper latch 31, connector 32, and lower latch 33 may be integrally formed. Preferably, the connector 32 may be a rope. In other embodiments, the connector 32 may also be made of metal wire, plastic strips, or the like.

[0031] When connected, the end of the upper latch 31 facing the lower latch 33 is tied and connected to one end of the rope (connecting member 32), and the other end of the rope (connecting member 32) is tied and connected to the end of the lower latch 33 facing the upper latch 31. Specifically, the upper latch 31 is arranged in an L shape, and the L-shaped upper latch 31 has a horizontal section and a vertical section. The horizontal section of the upper latch 31 faces the upper base 1, and the vertical section of the upper latch 31 is connected to the connecting member 32. Preferably, the end of the vertical section of the upper latch 31 forms a first hanging ring 34, and the connecting member 32 is fixedly connected to the first hanging ring 34. In order to further facilitate the use of the latch and make it easier to pull the latch, an open disassembly ring 30 is formed at the intersection of the horizontal section and the vertical section of the upper latch 31. During disassembly, an outsider can hold the open disassembly ring 30, making it more convenient to pull the latch or control the insertion of the latch.

[0032] In this embodiment, the lower latch 33 is arranged in a straight bar shape. The end of the lower latch 33 facing the connecting member 32 forms a second hanging ring 35. The rope (connecting member 32) is tied and fixedly connected to the second hanging ring 35.

[0033] As an improvement, the latch can assemble and disassemble two sets of buckle structures at the same time. The first buckle structure is the buckle 2 and the upper base 1, combined with Figure 3The upper base 1 is formed with a first through hole 12, and the side of the buckle 2 facing the upper base 1 is formed with a second through hole 22 aligned with the first through hole 12. As a preferred solution, the upper base 1 has three first pin sleeves 11 protruding outward on the side facing the buckle 2. The first through hole 12 is formed in the first pin sleeves 11. The upper base 1 also has a first latching position 13 located between two adjacent first pin sleeves 11. It should be noted that the first latching position 13 can be a latching hole or a latching slot, as long as it can perform the positioning function. In addition, the side of the buckle 2 facing the upper base 1 protrudes outward to form two second pin sleeves 21 arranged at intervals, and the second through hole 22 is formed in the second pin sleeve 21. During assembly, the second pin sleeve 21 is snapped into the first snap position 13, which can achieve rapid limiting and rapid alignment, providing a basis for the rapid assembly process and playing a fool-proof role. There is no need to deliberately align the buckle 2 with the upper base 1. As long as the second pin sleeve 21 is placed between the two first pin sleeves 11, the second pin sleeve 21 can enter the first snap position 13 to complete the limiting, ensuring that the first pin sleeve 11 and the second pin sleeve 21 are axially aligned, so that the first through hole 12 and the second through hole 22 are axially aligned. During assembly, the horizontal section of the upper plug 31 is passed through the first through hole 12 and the second through hole 22, that is, the horizontal end of the plug passes through the first through hole 12 and the second through hole 22, to complete the assembly of the first buckle structure. It is simple to use and easy and quick to operate. In other embodiments, the upper base 1 may also be provided with other structures for limiting, such as forming an arc-shaped baffle between two adjacent first pin sleeves 11. The baffle can be directly formed at the first locking position 13, which can also play a limiting role.

[0034] Combine Figure 4 , the second buckle structure controlled by the bayonet is a buckle structure composed of a socket assembly and a lower base 4. The buckle assembly includes a female buckle 51 and a male buckle 52 that cooperates with the female buckle 51 buckle 2. The male buckle 52 is fixed with a webbing 53 at one end away from the female buckle 51. The webbing 53 is mainly used to connect a certain part of the outer vest. The lower base 4 is formed with a third through hole 42. Specifically, the side of the lower base 4 facing the female buckle 51 protrudes outward to form three spaced third pin sleeves 41. The third through hole 42 is formed in the third pin sleeve 41. The lower base 4 is also provided with a second clamping position located between two adjacent third pin sleeves 41. In another embodiment, combined with Figure 5 The second position is formed with a pair of arc-shaped limiting plates 43 fixed to the lower base 4. The arc-shaped limiting plates 43 can play a limiting role, further improving the convenience of quick installation.

[0035] In this embodiment, the side of the female buckle 51 facing the lower base 4 is provided with a fourth through hole 60 aligned with the third through hole 42. Figure 6 and Figure 7The second snap-on structure (quick assembly and disassembly structure) also includes a fabric 6, a fourth pin sleeve 61 sewn to the left end of the fabric 6, and a shaft sleeve 62 fixed to the left end of the fabric 6. The shaft sleeve 62 is also sewn from a fiber tape. A pin 50 is formed on the end of the female buckle 51 facing the lower base 4. The pin 50 is inserted into the shaft sleeve 62, so that the end of the female buckle 51 facing the lower base 4 is connected to the fourth pin sleeve 61 sewn from the fiber tape. A fourth through hole 60 is formed in the fourth pin sleeve 61. During assembly, the fourth pin sleeve 61 is snapped into the second snap-on position, the third pin sleeve 41 and the fourth pin sleeve 61 are axially aligned, so that the third through hole 42 and the fourth through hole 60 are axially aligned, and one end of the lower pin 33 passes through the third through hole 42 and the fourth through hole 60, thus completing the quick installation of the second snap-on structure. In another embodiment, the fabric 6 and the sleeve 62 may be omitted, and the fourth pin sleeve 61 may be directly formed on the female buckle 51, thereby improving the female buckle 51 in the prior art and being suitable for the quick assembly and disassembly structure of this embodiment, requiring fewer assembly parts, and being more convenient and quick when assembled to the vest. It should be noted that because the fourth pin sleeve 61 is sewn from a fiber tape, it has a certain degree of flexibility. During quick installation, only the fourth through hole 60 needs to be partially aligned with the third through hole 42. When the lower pin 33 is inserted into the entrance of the fourth through hole 60, due to the certain flexibility of the fourth pin sleeve 61, the fourth through hole 60 in the fourth pin sleeve 61 will automatically align with the third through hole 42 during the continued insertion of the lower pin 33, thereby providing a basis for quick installation.

[0036] In order to improve the smoothness of the insertion of the pin into the through hole, the end of the lower pin 33 facing the lower base 4 is a cone. Similarly, the end of the horizontal section of the upper pin 31 is a cone.

[0037] Preferably, the ratio of the aperture size of the first through hole to the aperture size of the second through hole is 1:0.5-2, and the ratio of the aperture size of the third through hole to the aperture size of the fourth through hole is 1:0.5-2.

[0038] In this embodiment, in order to prevent the pin from slipping out, the axial direction of the first through hole 12 and the axial direction of the third through hole 42 are arranged perpendicular to each other, so that the upper pin 31 is limited by the lower pin 33, and the lower pin 33 is limited by the upper pin 31. Without a large pulling force, the upper pin 31 will not fall out of the first through hole 12 and the second through hole 22, and the lower pin 33 will not fall out of the third through hole 42 and the fourth through hole 60. Therefore, the pin adopts an L-shaped vertical structure, which can effectively prevent the buckle structure from separating during movement, further improving.

[0039] A specific embodiment of the vest of the present invention is shown in Figure 8The vest includes shoulder straps 74, a back body 72, a chest body 71, and the aforementioned quick-detachable assembly structure. One end of the shoulder strap 74 is sewn and fixed to the back body 72, and the other end of the shoulder strap 74 is sewn and fixed or bonded to the buckle 2. The upper base 1 is fixed to the chest body 71, facing the shoulder strap 74. A waistband portion 73 extends from the side of the back body 72 toward the chest body 71. The fabric 6 and the webbing 53 of the male buckle 52 are sewn to the waistband portion 73. The female buckle 51 of the buckle assembly is inserted into the male buckle 52 on the waistband portion 73. The lower base 4 is fixed to the chest body 71, facing the waistband portion 73. To prevent the connector 32 from falling and to facilitate the storage of the latch, the connector 32 is sewn to the chest body 71. Specifically, a small piece of fabric can be used, with both sides of the fabric sewn to the chest body 71, thereby forming a channel between the middle of the fabric and the chest body 71. The connector 32 is movably mounted in this channel.

[0040] When wearing and assembling, fold the shoulder strap 74 so that the second pin sleeve 21 of the buckle 2 on the shoulder strap 74 is inserted between the two first pin sleeves 11 of the upper base 1. At this time, the first through hole 12 and the second through hole 22 are aligned, and one end of the upper pin 31 passes through the first through hole 12 of the upper base 1 and the second through hole 22 of the buckle 2 to connect and fix the shoulder strap 74 to the chest body 71, completing the connection at the shoulder. Then fold the waist belt part 73 so that the fourth pin sleeve 61 of the fabric 6 is inserted between the two third pin sleeves 41 of the lower base 4. At this time, the third through hole 42 and the fourth through hole 60 are aligned, and the end of the lower pin 33 passes through the third through hole 42 and the fourth through hole 60 to connect the waist belt part 73 of the back body 72 to the chest body 71, completing the waist connection.

[0041] When disassembling the vest, the latch is pulled to disengage the second through hole 22 and the fourth through hole 60 , so that the shoulder strap 74 is separated from the chest body 71 and the waist belt portion 73 of the back body 72 is separated from the chest body 71 .

[0042] This embodiment of a quick assembly and disassembly structure and a vest having such a structure utilizes a latch as the primary connector 32. During disassembly or assembly, the entire structure can be disassembled or assembled simply by pulling out or inserting the latch. This provides simple and quick operation, convenient and rapid use, and a highly user-friendly design, resolving the cumbersome assembly and disassembly issues of the past. The overall structure is simple and compact, and the quick assembly and disassembly features high reliability and safety, making it suitable for use on various vests requiring rapid disassembly or assembly.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
