[0033] This utility model discloses a zipper placket structure for trousers and trousers, which solves the technical problem that users easily forget about the zipper when using trousers with zippers.
[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Please see Figures 1 to 6 The present invention provides a trouser zipper placket structure, including a placket 3 and a waistband 2 connected above the placket 3. The placket 3 is provided with a zipper 4 with a zipper head body 5. The waistband 2 is provided with a first buckle 6 and a second buckle 7 located on opposite sides of the placket 3 and capable of being fastened to each other.
[0036] The first buckle 6 and the second buckle 7 can be fastened together to form a first locking structure. The zipper head body 5 is provided with a second locking structure. The second locking structure is locked with the first locking structure to lock the first buckle 6 and the second buckle 7.
[0037] When the first locking structure is locked with the second locking structure, the waistband 2 forms a waist circumference of a first length; when the first locking structure is unlocked from the second locking structure, the waistband 2 forms a waist circumference of a second length; the first length is less than the second length.
[0038] In the trouser placket structure of this embodiment, after the user puts on the trousers, the first buckle 6 and the second buckle 7 need to be fastened to form a first locking structure. At this time, the user pulls the zipper 4 up through the zipper head body 5 and locks the second locking structure on the zipper head body with the first locking structure, thereby locking the first buckle 6 and the second buckle 7 together. In the above design, the user must lock the first locking structure on the zipper head body with the second locking structure for the first buckle 6 and the second buckle 7 to be fully locked together. At this time, the waistband 2 forms a first length of waist circumference, and the waistband 2 will be in a tight state, i.e., a normal wearing state. If the user does not lock the first locking structure with the second locking structure, the waistband 2 forms a second length of waist circumference. At this time, the waistband 2 will be in a relatively loose state but will not fall off the user's buttocks. Therefore, through the above design, the situation of the user forgetting to zip up can be effectively avoided.
[0039] Furthermore, in this embodiment, the second locking structure is a locking pin 8 disposed on the zipper head body 5. Specifically, the locking pin 8 in this embodiment can be disposed at any position on the zipper head body 5, as long as it can engage with the locking through groove. In addition, the locking pin 8 can be fixed to the zipper head body 5 by means of pressing, welding, bonding, injection molding, die casting, etc., and this embodiment does not impose any restrictions on this.
[0040] The first fastener 6 has a limiting opening 601 on its top surface and an active space 602 inside, which communicates with the limiting opening 601. The first fastener 6 has a first locking through hole 603 at its bottom. The second fastener 7 has an insertion part 701 at one end facing the first fastener 6 that matches the limiting opening 601. The insertion part 701 can be inserted vertically into the active space 602 through the limiting opening 601 and driven to move horizontally along the active space 602. The insertion part 701 has a second locking through hole 702 that penetrates the insertion part 701 vertically.
[0041] When the insertion part 701 is inserted into the movable space 602 through the limiting port 601, the limiting port 601 is driven to move horizontally along the movable space 602 so that the first locking through hole 603 and the second locking through hole 702 are aligned to form a locking through groove, and the locking through groove is the first locking structure.
[0042] When the zipper head body 5 locks the zipper 4 to close the placket 3, the locking pin 8 engages in the locking groove to lock the first buckle 6 and the second buckle 7.
[0043] Additionally, it should be noted that when the locking pin 8 disengages from the locking groove, the second buckle 7 can still slide horizontally. However, at this time, the first buckle 6 and the second buckle 7 are not locked. Therefore, the waistband 2 is in a relatively loose state to facilitate the user's toilet needs, but the waistband 2 will not fall below the buttocks.
[0044] Specifically, in this embodiment, the active space 602 extends horizontally. When the insertion part 701 is inserted into the active space 602, the insertion part 701 can move horizontally along the active space 602 so that the user can align the first locking through hole 603 with the second locking through hole 702.
[0045] Furthermore, in this embodiment, the limiting opening 601 is a T-shaped opening;
[0046] The insertion part 701 is a T-shaped structure that matches the shape of the T-shaped opening.
[0047] It should be noted that the limiting port 601 and the insertion part 701 described above are only one specific implementation of this embodiment. The limiting port 601 and the insertion part 701 can also be designed in other shapes, and this embodiment does not limit them.
[0048] Furthermore, in this embodiment, limit walls 604 are provided at opposite ends within the activity space 602;
[0049] When the insertion part 701 is driven to move to the opposite ends of the active space 602, the limiting wall 604 abuts against the active space 602 to restrict the movement of the insertion part 701.
[0050] It should be noted that the above design can limit the range of movement of the insertion part 701 within the active space 602.
[0051] Furthermore, in this embodiment, the diameter of the first locking through hole 603 is the same as the diameter of the second locking through hole 702.
[0052] It should be noted that the above design ensures that the dimensions of the locking through groove formed by the first locking through hole 603 and the second locking through hole 702 are consistent, which facilitates the insertion of the locking pin 8 into the locking through groove to lock the first buckle 6 and the second buckle 7.
[0053] Furthermore, in this embodiment, the corners of the first fastener 6 and the second fastener 7 are both rounded.
[0054] The above design makes the corners of the first buckle 6 and the second buckle 7 more rounded to avoid causing injury to the user.
[0055] Furthermore, in this embodiment, the placket 3 is also provided with an outer placket fabric, which is used to cover the zipper 4.
[0056] It should be noted that, through the above design, the outer placket can cover the zipper 4, making the pants more aesthetically pleasing.
[0057] Furthermore, in this embodiment, the first fastener 6 or the second fastener 7 is movably connected to the waistband 2.
[0058] Specifically, the first buckle 6 or the second buckle 7 is provided with a sliding adjustment groove, and the waistband 2 is provided with a sliding part that is slidably connected to the sliding adjustment groove;
[0059] The sliding adjustment groove includes a transverse sliding groove for the sliding part to move horizontally and a longitudinal sliding groove for the sliding part to move vertically. Multiple longitudinal sliding grooves are provided, and the multiple longitudinal sliding grooves are connected to the transverse sliding grooves at intervals. The longitudinal sliding grooves and the transverse sliding grooves are arranged perpendicularly or inclined to each other. Designers can design according to the actual situation.
[0060] In addition, in the above structure, in order to achieve the limiting effect on the sliding part, the width of the end of the longitudinal slide groove away from the transverse slide groove needs to be greater than the width of the longitudinal slide groove.
[0061] The number of sliding parts is at least two.
[0062] It should be noted that when adjusting the waist size of the pants, the user can slide the sliding part into different longitudinal grooves to adjust the waist size of the pants.
[0063] Please see Figures 1 to 6 The present invention provides a pair of trousers, including the above-mentioned trouser zipper placket structure.
[0064] In this embodiment of the pants, after the user puts on the pants, the first buckle 6 and the second buckle 7 need to be fastened to form a first locking structure. At this time, the user pulls the zipper 4 up through the zipper head body 5 and locks the second locking structure on the zipper head body with the first locking structure, thereby locking the first buckle 6 and the second buckle 7 together. In the above design, the user must lock the first locking structure on the zipper head body with the second locking structure for the first buckle 6 and the second buckle 7 to be fully locked together. At this time, the waistband 2 forms a first length of waist circumference, and the waistband 2 will be in a tight state, that is, a normal wearing state. If the user does not lock the first locking structure with the second locking structure, the waistband 2 forms a second length of waist circumference. At this time, the waistband 2 will be in a relatively loose state but will not fall off the user's buttocks. Therefore, through the above design, the situation of the user forgetting to zip up can be effectively avoided.
[0065] The foregoing has provided a detailed description of a zippered placket structure for trousers and the trousers themselves. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
