Description

Technical Field

[0001] The invention relates to a case and bag, and more particularly to a detachable, mutually-assembled and interchangeable case and bag. Background Art

[0002] At present, most of the luggage (mainly trolley cases) are used directly after users buy them. The merchants have assembled the left and right case shells, zippers, etc. together. Usually, the manufacturer's practice is to sew the torn single-sided zipper tape on the edges of the left and right case shells, install a pull rod on one of the case shells and install two opposite traction wheels on the left and right case shells, and then use the pull head to pull the teeth together to the other end of the zipper. Due to the circumference tolerance of the case mouth during manufacturing and the slip difference in the process of sewing the respective single-sided zipper tapes, the left and right case shells are twisted after the case is assembled, causing the four traction wheels to be unbalanced. It is necessary to make a misalignment correction on the tooth base points of the left and right zippers to achieve the balance of the four traction wheels at the bottom of the case on the same plane, and then put on another opposite pull head, and then fix the two zipper ends with glue, and then sew the two case shells together with tape strips laterally. The disadvantage of this traditional method is that when the zipper head of the luggage is broken or the pull tab is broken, the user has no way to replace it. Secondly, this balance correction method cannot completely correct the left and right misalignment after the zipper is closed. The zipper teeth may burst and break at the bending part of the box shell. Finally, it cannot be disassembled and adjusted because the end is fixed with glue. If you have to replace the slider or pull tab, you must cut off the glued part. If there is no glue, you may worry that the luggage will fall during transportation and cause the chain teeth to break. Although there was a patent application number 2019113195937 before this creation, the name is: a detachable, interchangeable luggage, which includes left and right chain belts sewn on the upper box shell of the trolley case and the edge of the lower box shell with a pull rod installed, and a main zipper composed of pull heads for opening and closing the left and right chain belts, which is characterized in that a movable lower stop is installed at one or both ends of the left and right chain belts to prevent the pull head from detaching from the main zipper, the core wire of the chain belt end at the position where the movable lower stop is installed is ultrasonically fixed together with the tape and the cloth tape by hot sticking, and a row of longitudinal positioning holes with the same spacing is formed on the chain belt at the position where the movable lower stop is installed, the movable lower stop is a U-shaped clip, and a connecting plate is extended in the opposite direction on one foot of the U-shaped clip, and a row of raised positioning teeth are provided on the surface of the connecting plate, the shape and spacing of the positioning teeth match the positioning holes, the number of positioning holes is greater than the number of positioning teeth, the positioning teeth of the movable lower stop are inserted in the positioning holes of one chain belt, and the U-shaped clip is clamped on the other chain belt. The structure has positioning holes at one or both ends of the left and right chain belts, and a movable lower stopper is installed on the positioning hole to prevent the slider from being separated from the main zipper. This method can conveniently and quickly sew the left and right chain belts to the upper and lower box shells, so that the upper and lower box shells can be assembled at will in the future to achieve a completely matched effect. However, the disadvantage is that positioning holes must be made on the left and right chain belts, which is troublesome and affects the production efficiency.Later, there was a publication number CN111096524A, which is a detachable, interchangeable bag, which includes a left and right chain belt, and a pull head and a movable stopper for opening and closing the left and right chain belts. The front half of the movable stopper is a loop composed of an upper cover plate and a lower cover plate of two opening frames facing each other. The size, mouth height, mouth width and gap of the cloth seam of the looper are consistent with the mouth height, mouth width and gap of the cloth seam of the chain head. The gap is the same, the rear half of the loop is a positioning plate extending backward on the lower cover plate, a side connecting plate is provided on the left or 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 comb grid is made on the positioning plate and the side connecting plate, the comb grid is a row of raised comb teeth, the shape and pitch of the comb teeth match the corresponding chain teeth, and are fixed together with the chain teeth on the single-side chain belt, and the loop is engaged with the tooth sections at both ends of the left and right chain belts. This closed zipper is used to open and close the zipper of the trolley case by hooking the two positioning plates on the fastener and getting stuck in the gap, fixing the two movable stops together. However, in actual use, especially during air consignment, the trolley case is swung back and forth, causing the hook to be unhooked, the two ends of the closed zipper to separate, and an opening appears at the connection between the two ends of the zipper of the trolley case, and the items in the trolley case will scatter from the opening, causing unnecessary losses to passengers. Summary of the invention

[0003] The purpose of the present invention is to provide a detachable interchangeable luggage with a simple structure and convenient sewing. When the left and right chain belts are sewn and adjusted, if the lengths of the two ends of the left and right chain belts are inconsistent, a stopper can be easily installed.

[0004] In order to meet the above requirements, a technical solution for detachable and interchangeable luggage is as follows: it includes a zipper sewn on the luggage, and a slider for opening and closing the zipper, and a T-shaped plate is installed at the butt joint of the two ends of the annular zipper from the outside of the folded position of the luggage inward, and the T-shaped plate is composed of a straight plate and a straight handle fixed in the middle of the straight plate and perpendicular to the straight plate, and is characterized in that a row of upwardly protruding comb teeth and / or upright columns are provided on the inner surface of the straight plate on both sides of the straight handle, and the two comb teeth and / or upright columns are respectively engaged with the chain teeth at the two ends of the extended single-sided chain belt and fixed together, and the two ends of the zipper are fixed by the T-shaped plate, and a clamping device with a cover plate is added to the straight handle to fix the two ends of the zipper between the straight plate and the cover plate.

[0005] The comb-shaped teeth and / or upright columns are first made on the movable stopper, and then fixed by the movable stopper and the straight plate. The front half of the movable stopper is a loop composed of an upper cover plate and a lower cover plate with two opening frames facing each other. A positioning plate is extended backward on the lower cover plate. A row of upwardly protruding comb-shaped teeth and / or upright columns are formed on the positioning plate. The comb-shaped teeth and / or upright columns are engaged with the chain teeth on the extended single-sided chain belt and fixed together. An annular sleeve is formed behind the positioning plate. The loop is engaged with the tooth sections at both ends of the zipper. A T-shaped plate is installed at the butt joints at both ends of the annular zipper from the outside of the bag to the inside. The annular sleeves on the movable stops at both ends of the zipper are both mounted on the straight handles of the T-shaped plate to fix the two ends of the zipper together. A clamping device with a cover plate is added to the straight handle.

[0006] The clamping device is a rectangular clamping block fixed on the top of the straight handle, a rectangular through hole matching the shape of the clamping block is formed in the middle of the cover plate, a clamping handle is mounted on the cover plate, a rectangular through hole matching the shape of the clamping block is also formed in the middle of the clamping handle, when locking is required, the clamping handle is inserted into the clamping block and rotated 90 degrees, and the movable stop buckle is pressed between the straight plate and the cover plate by the clamping block to fix it.

[0007] The clamping device is a cover plate sleeved on the straight handle, and the two ends of the zipper are buckled and pressed between the straight plate and the cover plate by the threaded structure of screws or nuts on the top of the straight handle above the cover plate to fix them.

[0008] The number of the comb-shaped teeth and / or columns is 3-6.

[0009] A side connecting plate is provided on the left or right side of the positioning plate, and the upper cover plate and the positioning plate are fixed on the side connecting plate through a connecting arm, and the comb-shaped teeth are also connected to the side connecting plate.

[0010] A stopper protruding from the surface of the positioning plate is arranged on the edge of the positioning plate opposite to the side connecting plate, and the extended single-side chain belt is clamped between the side connecting plate and the stopper.

[0011] The outer surface of the positioning plate is covered with an anti-loosening sleeve made of plastic or rubber, and the anti-loosening sleeve wraps the chain teeth embedded in the positioning plate together and prevents them from being separated and falling off.

[0012] The luggage includes a trolley case, in which one or two annular thickening boxes for increasing the width of the case are connected by a zipper between two pairs of left and right case shells, and the corresponding straight plate of the T-shaped plate and the cover plate are in the shape of a three-way with a shape of ┣ or a four-way with a shape of ╋.

[0013] The annular thickening box is formed by a strip belt with the same width as the thickening box and zippers sewn on both sides, and the two ends are closed by transverse zippers.

[0014] According to the above scheme, a detachable, interchangeable luggage is designed. After the balance is corrected by a loop-type grid and a convex column, the left and right sides of the zipper teeth are unequal in length after the misalignment correction, and one side of the single-sided chain tooth is longer. The loop-type movable stopper creation component is inserted into the zipper tooth section for protection against lateral tension, and the longer single-sided chain belt is pressed into the grid and the convex column for longitudinal locking. The locking section can be designed with an injection-molded sleeve, which is inserted into the locking section for secondary protection to prevent it from falling and loosening. Then, the annular sleeve on the movable stopper is put on the straight handle of the T-shaped plate to fix the two ends of the zipper together. A clamping device with a cover plate is added to the straight handle to achieve the function of covering and combining the gaps of the two ends of the zipper. The above creation structure can meet the use requirements of interchangeable and interlocking of the same type and shell, and can make production operations more convenient and rapid. During use, when the zipper head and pull tab are damaged, the user can also replace them by himself without the help of any tools. Manufacturers and users of trolley cases can also add thickening boxes of different thicknesses between the upper and lower case shells to expand the capacity of the trolley case and achieve DIY multi-style combinations. This saves time and effort, and the left and right case shells can be quickly disassembled and reassembled by interchanging. In addition, the left and right case shells can be stacked together without being assembled into a complete trolley case, saving packaging and transportation costs, and "exporting semi-finished products" also saves tariffs. It has the advantages of simple structure, easy disassembly and reliable connection. BRIEF DESCRIPTION OF THE DRAWINGS
