[Technical Field] The present invention relates to the technical field of underwear design, in particular to a combined underwear.

[Background Art] Existing undergarments are one-piece, back-opening or front-opening, but none of them have the function of adjusting the size of the lower circumference. When the underwear purchased by the user does not meet the size of the lower circumference or the body curve changes, it is necessary to re-purchase underwear with a suitable lower circumference size, resulting in the underwear not meeting the lower circumference size being not used or discarded, resulting in waste. Therefore, a solution is urgently needed. In addition, underwear can be divided into front button type and back button type according to the way of wearing. Among them, the front button underwear means that the fastener is set in front of the lace and is located between the two cups; while the back button underwear means that the fastener is set behind the lace and is located on the back of the wearer. The fastener can be set to be adjustable. , so that the girth of the straps can be adjusted to match the circumference of the underbust. A fastener can also be provided at the joint between the shoulder strap and the cup for easy disassembly and cleaning; the fastener can also be set as an adjustment fastener for size adjustment. Most of the shoulder straps of existing underwear and other underwear are connected by "6"-shaped or "8"-shaped one-way detachable buckles or non-detachable buckles. The underwear is bound, or tied to the shoulder straps, so that some underwear cannot be used after the attachment buckle is damaged. Now many underwear belts have tended to be diversified and colorful, and have already become a part of clothing decoration, and their connection with underwear naturally requires a more flexible and more independent direction. manual

It can be understood that when the first positioning member 15 and the second positioning member 35 are separated from each other, that is, when the two are out of position, the lock catch 3 gradually opens the pin opening 22 . Specifically, the middle of both ends of the fixed shaft 1 is provided with a symmetrical protrusion, and the middle of both ends of the lock 3 is provided with a symmetrical recess. When the lock 3 slides on the first surface 10a to the symmetrical recess in the middle of the lock 3 When the in-position is connected with the symmetrical protruding position, continue to push the lock catch 3, so that the symmetrical concave position and the symmetrical protruding position engage with each other. At this time, the positioning of the locking clasp 3 to close the pin opening 22 is realized. Of course, the middle parts of both ends of the fixed shaft 1 are set as symmetrical concave positions, and the middle parts of both ends of the locking buckle 3 are set as symmetrical convex positions, so that the locking buckle 3 can also realize the positioning of closing the pin opening 22 . In order for the lock 3 to slide more stably on the first surface 10a, the first surface 10a of the fixed shaft 1 is provided with a first guide rail 19, and the side of the lock 3 facing the connecting piece is provided with a second guide rail 39, the first guide rail 19 and the second guide rail 39 The two guide rails 39 are combined so that the lock catch 3 is directly above the first surface of the fixed shaft 1 and parallel to the fixed shaft 1, and the second guide rail 39 slides along the first guide rail 19, so that the first positioning member 15 can be aligned with the second guide rail 1. The two positioning members 35 engage with each other, thereby positioning and sliding each other. Specifically, the first guide rail 19 is configured as a convex strip, and the second guide rail 39 is configured as a concave strip, and the convex strip and the concave strip cooperate with each other to slide. The first guide rail 19 is configured as a concave strip, and the second guide rail 39 is configured as a convex strip, which can also cooperate with each other to slide. Please refer to FIG. 12 to FIG. 14 , the use process of the above-mentioned embodiment of the present invention is as follows: firstly push the buckle 3 to one side, so that the pin opening 22 is exposed, and then put the shoulder strap through the pin opening 22 After the insertion is completed, reversely push the lock 3 to close the pin opening 22, from WO 2022/263940 specification PCT/IB2022/054554 to fix the shoulder strap; then push the buckle to the other side to fix the other shoulder strap. The holes are used to fix the decorative parts, so as to realize the fixing of the two shoulder straps, and at the same time, it is more beautiful. The invention is easy to put on and take off, and is suitable for wearers with different lower circumference sizes, thereby improving the utilization rate of the underwear. The above examples only express the preferred implementation of the invention, and the descriptions are more specific and detailed, but should not be construed as limiting the patent scope of the invention. It should be noted that, for those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, such as combining different features in the various embodiments, etc., all of which are Belong to the protection scope of the present invention.
