Description

Detachable mutually-spliced interchange case

Technical Field

The invention relates to a case, in particular to a detachable mutually-spliced interchange case.

Background

At present, most cases (mainly draw-bar cases) are directly used after being bought by users, and left and right cases, zippers and the like are assembled together by merchants. The conventional manufacturer has the practice of sewing torn single-side zipper strips on the peripheral openings of the left and right box shells which are equal, installing a pull rod on one box shell, installing two opposite dragging wheels on the left and right box shells respectively, and then using a pull head as a closing tooth to close the other end of the zipper. The perimeter tolerance of the case opening and the slip in the process of sewing the respective unilateral zipper tapes of the vehicle during manufacturing cause the left case shell and the right case shell to be twisted after the case is combined, so that four dragging wheels are unbalanced, the dislocation and tooth combination correction must be carried out on the tooth combination base points of the left zipper and the right zipper, the four dragging wheels at the bottom of the case are balanced on the same plane, then the other opposite direction puller is worn, the tail ends of the two zippers are fixed by glue dispensing, and the two case shells are sewn together by a rubberized fabric strip in the lateral direction. The traditional method has the defect that when the opening and closing zipper head of the case is broken or the pulling piece is broken, a user cannot replace the zipper head. Secondly, the left and right malposition after the zipper is pulled and closed can not be completely corrected by the balance correction method, the zipper container is burst to open at the bending part of the box shell, and finally the zipper container can not be detached and adjusted because of tail end glue dispensing fixation. Although the title of patent application No. 2019113195937 existed before the present creation: a detachable case with mutually spliced and interchangeable bags comprises a left zipper belt and a right zipper belt which are sewn on the opening edge of an upper case shell of a draw-bar case and a lower case shell provided with a draw bar, and a main zipper consisting of pull heads for opening and closing the left zipper belt and the right zipper belt, and is characterized in that a movable lower stop for preventing the pull heads from being separated from the main zipper is arranged at one end or two ends of the left zipper belt and the right zipper belt, a core wire at the end of the zipper belt at the position of the movable lower stop is fixed with a tape by hot sticking of ultrasonic waves, a row of longitudinal positioning holes with the same interval are formed on the zipper belt at the position of the movable lower stop, the movable lower stop is a U-shaped clamp, a connecting plate extends reversely on one foot of the U-shaped clamp, a row of raised positioning teeth are arranged on the surface of the connecting plate, the shapes and the intervals of the positioning teeth are matched with the positioning holes, the number of the positioning holes is greater than that, the U-shaped clip is clamped to the other chain. The structure is provided with positioning holes at one end or two ends of the left and right chain belts, and movable lower stoppers for preventing the pull heads from separating from the main zipper are arranged on the positioning holes. The method can conveniently and quickly sew the left and right chain belts on the upper and lower cases, and the upper and lower cases can be assembled at will later, so as to achieve the effect of complete involution. But the defects are that positioning holes are needed to be arranged on the left and the right chain belts, which is troublesome and influences the production efficiency. Although a detachable mutually-spliced interchange luggage is also disclosed in the publication No. CN111096524A, which comprises a left chain belt, a right chain belt, a pull head for opening and closing the left chain belt and the right chain belt, and a movable stop, and is characterized in that the front half part of the movable stop is a loop consisting of an upper cover plate and a lower cover plate which are opposite up and down, the size of the upper cover plate and the lower cover plate of the loop is the same as the opening height, the opening width and the clearance for passing the cloth seam of the teeth-closing end of the chain head, the rear half part of the loop is a positioning plate which extends backwards on the lower cover plate, a side connecting plate is arranged on the left side or the right side of the positioning plate, the upper cover plate and the positioning plate are fixed by a connecting arm on the side connecting plate, a section of comb grid is arranged on the positioning plate and the side connecting plate, the comb grid is a row of raised comb teeth, the shape and the tooth pitch of the comb teeth are matched with the opposite chain, and is embedded and fixed with the teeth on the single-side chain belt, and the movable sleeve is encircled on the gear engaging sections at the two ends of the left and right chain belts. The zipper for opening and closing the draw-bar box of the closed zipper is characterized in that the two positioning plates are hooked by the hooks on the fasteners and clamped in the notches, and the two movable stoppers are fixed together. However, in practical use, particularly in aviation transportation, the draw-bar box is thrown to throw away, so that the hook is hooked and unhooked, two ends of the closed zipper are separated, an opening is formed at the joint of the two ends of the zipper of the draw-bar box, and articles in the draw-bar box can fall out from the opening, so that unnecessary loss is caused to passengers.
