Description

Detachable interchangeable bags

The present invention refers to a detachable and interchangeable luggage, and more particularly relates to a detachable and interchangeable luggage.

Press, most of the current luggage (mainly refers to the trolley case), the user buys it and uses it directly, and the merchant has assembled the left and right case shells, zippers, etc. together. Usually the manufacturer's practice is to first sew the torn unilateral zipper tapes on the edges of the left and right box shells, respectively, install a pull rod on one of the box shells, and install two on the left and right box shells respectively. A pair of opposite pull wheels, and then pulled by the slider to the other end of the zipper. Due to the perimeter tolerance of the box opening during manufacture and the slippage of the car during the sewing of the respective unilateral zipper tapes, the left and right box shells are twisted after the luggage is combined, resulting in an imbalance of the four tractor wheels. , Correct the misalignment of the teeth of the right zipper to achieve the balance of the four pulleys at the bottom of the bag on the same plane, then put on another opposite slider, and then fix the ends of the two zippers with glue. Then sew the two case shells together with tape strips sideways. The disadvantage of this traditional method is that when the opening and closing zipper head of the bag is broken or the pull piece is broken, the user cannot replace it. Secondly, this balance correction method cannot completely correct the left and right misalignment after the zipper is pulled and closed. The zipper is broken at the bend of the box shell, and finally cannot be disassembled and adjusted due to the glue at the end. If you have to replace the slider , The pull tab must be cut off the dispensing part. If there is no dispensing, it is afraid that the luggage will be dropped during transportation and the chain tooth belt will be cracked. Although there is a patent application No. 2019113195937 before this creation, the name is: a detachable interlocking and interchangeable luggage, which includes left and right chain straps sewn on the upper shell of the trolley case and the edge of the lower box shell installed with the trolley, and The main zipper formed by the sliders of the left and right chain belts for opening and closing the left and right chain belts is mainly provided with a movable lower block at one end or both ends of the left and right chain belts to prevent the slider from being separated from the main zipper. The core wire at the end of the chain belt at the position is fixed by ultrasonic wave to heat the tape and the cloth tape together, and a row of longitudinal positioning holes with the same spacing is made on the chain belt at the position of the movable lower block. The movable lower block is a U. A connecting plate is reversely extended on one foot of the U-shaped clip, and a surface of the connecting plate is provided. There is a row of raised positioning teeth, the shape and spacing of the positioning teeth are matched with the positioning holes, the number of positioning holes is greater than the number of positioning teeth, the positioning teeth of the movable lower gear are inserted into the positioning holes of a chain belt, and the U-shaped The clip is clamped to the other chain belt. The structure is provided with positioning holes at one end or both ends of the left and right chain belts, and a movable lower block is installed on the positioning holes to prevent the slider from being separated from the main zipper. The method can conveniently and quickly sew the left and right chain belts on the upper and lower case shells, so that the upper and lower case shells can be assembled at will in the future to achieve the effect of complete matching. But the disadvantage is that positioning holes must be made on the left and right chain belts, which is troublesome and affects the efficiency of production. Although there is a later publication number CN111096524A, a detachable interchangeable luggage bag, which includes left and right chain belts, as well as a slider for opening and closing the left and right chain belts and a movable stop, which is characterized by the movable stop. The front half of the stopper is a looper composed of two open frame-shaped upper and lower cover plates facing up and down. The gap is the same as the mouth height, mouth width and the gap through which the cloth seam passes through the toothed end of the chain head. The rear half of the looper is extended backward on the lower cover plate with a positioning plate, and the left or right side of the positioning plate is provided with a side connecting plate , the upper cover plate and the positioning plate are fixed on the side connecting plate through the connecting arm, and a section of comb grid is made on the positioning plate and the side connecting plate, and the comb grid is a row of raised comb teeth. The shape and tooth pitch are matched with the opposite chain teeth, and are fitted and fixed together with the chain teeth on the one-side chain belt, and the looper is hugged on the tooth segments at both ends of the left and right chain belts. The zipper of the closed zipper used for opening and closing the trolley case is that the hooks on the fastener hook the two positioning plates and clamp them in the notches to fix the two movable stops together. However, in actual use, especially in air transportation, the trolley case is thrown around, causing the hook to come off the hook, the two ends of the closed zipper are separated, 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 It will be scattered from the opening, causing undue losses to passengers.

In view of this, the inventor of the present invention finally created and designed a detachable and interchangeable luggage through continuous research, improvement and testing.

The main purpose of the present invention is to provide a detachable interchangeable luggage bag, which can meet the use requirements of the same type and the same shell, and can make the production operation more convenient and rapid. Users can also easily replace without any tools.
