[0037] A further improvement is that the box body is a plastic box body.

[0038] A further improvement is that the cover is a plastic cover or a cloth cover.

[0039] By adopting the above technical solution, the beneficial effects of the present invention are: In this case, the front shell and the rear shell are fixedly connected to form the body of the suitcase, and a pick-up and placement opening and a cover body for closing the pick-up and placement opening are set on one or both end faces of the body, and the cover body is connected to the body by a zipper, and the pick-up and placement opening is released by flipping open the cover body to take and place items. Compared with traditional suitcases, this case reduces the unfolded area of ​​the suitcase when opening the suitcase to take and place items, making it easier to take and place items, and the pick-up and placement opening area is smaller than the shell port area, which can reduce the exposed area of ​​items when opened, improving the consumer's experience.

[0040] A further beneficial effect is that the inner chain belt of the zipper is wrapped around and sewn and fixed on the periphery of the cover body, and the outer chain belt is sewn and fixed on the rubber strip. The fixing groove in the quick-release groove and the bent hook part of the rubber strip are hooked with each other to limit the rubber strip from leaving the quick-release groove. This is conducive to using the rubber strip to quickly plug and install the cover body on the box body without the assistance of tools, thereby greatly improving the production efficiency of luggage.

[0041] A further beneficial effect is that the fixed protrusions in this case can be arranged around the side wall of the quick-loading slot, or a plurality of fixed protrusions can be distributed on the side wall of the quick-loading slot at intervals. Preferably, the spacing distribution is adopted, which is conducive to reducing the material used to reduce the weight of the bag. The openings opened at the intervals at the bottom of the quick-loading slot are conducive to further reducing the material used to reduce the weight of the bag.

[0042] A further beneficial effect is that the rubber strip can be sewn on the zipper in one piece, or in multiple pieces, or in multiple pieces at intervals. No matter which setting method the rubber strip is in, the cover can be quickly assembled on the box. The setting method of the rubber strip in one piece is conducive to quickly sewing the rubber strip to the zipper. The multi-segment spacing distribution method of the rubber strip is conducive to reducing the length of the rubber strip in use and reducing the weight of the luggage.

[0043] A further beneficial effect is that the inclined surface arranged on the outer edge of the cover increases the angle between the inner and outer chain straps of the zipper, making it easier for the zipper head to slide.

[0044] A further beneficial effect is that the storage cavity of the suitcase can be used to store items directly, or an inner layer can be set. The inner layer blocks the uneven inner surface of the box body, increases the aesthetics of the interior after the box body is opened, and prevents some burrs on the inner surface of the suitcase from hooking clothes. After the inner layer is set, an inner bag can be sewn on the inner layer to locate and store some scattered small items. If the luggage is a single-end opening and closing cover, the inner layer is set with one layer and laid flat on the inner wall of the box body; if the luggage is a double-end opening and closing cover, the inner layer can be set with one layer or two layers. If one layer is set, the inner layer has double-sided ports, and the peripheries of the two ports are respectively fixed on the box body of the corresponding side access opening periphery; if two layers are set, the peripheries of the ports of the inner layer are respectively set on the box body of the corresponding side access opening periphery. The bottom surfaces of the double-layer inner layers can interfere with each other, which is convenient for flexible allocation of the storage space size formed by the single-side inner layer.

[0045] Further beneficial effects are: the port periphery of the inner layer can be directly sewed or glued to the inner surface of the box at the access opening periphery; it can also be sewed on the rubber strip together with the outer chain of the zipper to simplify the process; it is also possible to glue or sew the bone strip on the port periphery of the inner layer, so that when the rubber strip is inserted and fixed to assemble the cover body, the rubber strip and the bone strip are used to form a movable connection to fix the bone strip and the periphery of the inner layer on the box body, thereby improving the assembly efficiency of the bag, and the inner layer is not sewn on the zipper tape together with the rubber strip, which can improve the sewing efficiency of the rubber strip and the zipper, thereby improving the production efficiency of the bag. Therefore, the inner layer is preferably set in a bone strip connection mode.

[0046] A further beneficial effect is that a coat can be provided on the outer surface of the case, and the pattern of the coat can be used to increase the beauty and personalization of the outer surface of the case, which is conducive to providing suitcases with different patterns for consumers to choose from.

[0047] Further beneficial effects are: the port periphery of the outer garment can be directly sewed or glued to the outer surface of the case; it can also be sewed together with the outer chain of the zipper on the rubber strip, and the outer garment can be quickly fixed by the quick plug-in fixation of the rubber strip; it can also share the same bone strip with the inner layer or set an outer bone strip separately, and use the quick fixation plug-in of the rubber strip to quickly fix and install the outer garment. If the case is only provided with a take-in and put-out opening on one end face, the outer garment has one port; if the case is provided with a take-in and put-out opening on both end faces, the outer garment has double-sided ports, and the port on the other side is fixed to the case in the same way. The provision of the outer garment also increases the assembly connection stability of the front shell and the rear shell.

[0048] A further beneficial effect is that the front shell and the rear shell are connected to each other by using the first fixing plate to be fixedly inserted into the slot formed between the second fixing plate and the shell, and the latch on the first fixing plate and the latch on the box body or the second fixing plate are self-fixedly connected in an inseparable manner, without the need for cumbersome locking bolts or rivets, reducing labor costs and locking material costs, shortening the production cycle of luggage, greatly improving the assembly efficiency of the front shell and the rear shell, and improving the production efficiency of luggage.

[0049] A further beneficial effect is that the reinforcing strips provided on the first fixing plate and the second fixing plate increase the strength of the first fixing plate and the second fixing plate, and improve the connection stability between the front shell and the rear shell.

[0050] A further beneficial effect is that the reinforcing strip extends along the inner wall of the box to the access opening, and utilizes the arcuate inner wall of the box to convert the external impact pressure on the front and rear ends of the box into the anti-eversion strength of the first fixing plate and the second fixing plate, thereby improving the connection reliability between the front shell and the rear shell.

[0051] A further beneficial effect is that the pull rod assembly is invisibly embedded in the box body using an inner bushing and an outer bushing, which improves the smoothness of the appearance of the luggage and improves the appearance of the luggage. The pull rod assembly uses a pull rod assembly that can bounce up when a button on the handle is pressed, making it easy to take out the handle for use.

[0052] A further beneficial effect is that the pull rod structure is arranged in the middle of the top surface of the box body, so as to improve the symmetry and aesthetics of the box body. Although the installation opening destroys the connection stability between the front shell and the rear shell on the top surface of the box body, the stability of the assembly of the front shell and the rear shell on the top surface of the box body is enhanced under the restricted movement of the positioning column, the positioning hole and the mounting column, and the mounting sleeve passing through the shell body, as well as the fixed clamping of the inner sleeve and the outer sleeve. The pull rod structure is used to strengthen the connection strength between the front shell and the rear shell on the top surface of the box body, thereby preventing the upper end of the box body from cracking during use.

[0053] A further beneficial effect is that the lower end of the box body is fixedly connected by bolts of a socket provided at the lower end of the telescopic rod of the pull rod assembly to strengthen the connection strength between the front shell and the rear shell at the lower end of the box body, thereby preventing the lower end of the box body from cracking during use.

[0054] A further beneficial effect is that the provision of the anti-collision strip improves the overall anti-collision performance of the luggage and avoids deformation of the luggage body under impact.

[0055] A further beneficial effect is that the anti-collision strips arranged at the two corners of the lower end of the box are arranged on the connection track line between the front shell and the rear shell, which is conducive to strengthening the assembly strength of the front shell and the rear shell by utilizing the installation connection of the anti-collision strips.

[0056] A further beneficial effect is that the luggage can utilize the pull rod to drive the box body to be lifted and driven to slide forward and backward, and a handle can also be provided to drive the box body to move.

[0057] A further beneficial effect is that the cover body is arranged as a deformable cloth cover body, which is helpful in buffering the impact force on the front of the bag.

[0058] A further beneficial effect is that the storage bag provided on the cover can be used to store small scattered items, documents and airline tickets that need to be taken out frequently, or office supplies and electronic devices such as laptops and tablets, thereby improving the convenience of the bag.
