Description

Technical Field

[0001] The utility model relates to the technical field of luggage, in particular to a front-opening trolley case with an easy-to-install front cover. Background Art

[0002] Chinese utility model CN212345639U discloses a suitcase whose side and bottom edges of the case cover are located in the same plane, so as to overcome the high requirements of the production process for the curved zipper and the edging, reduce the difficulty of operation and increase the output of the suitcase. However, a fixed single product cannot meet the consumer group's pursuit of new styles and new appearance products. However, the production of new products requires more mold opening costs. In order to meet consumer demand and control costs, a front-opening suitcase with an easily replaceable front cover is designed to further improve the product structure and reduce the difficulty of the production process. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a front-opening trolley case with an easy-to-install front cover, which solves the problem that the existing trolley cases are assembled and fixed and cannot be easily replaced.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a front-opening trolley case with an easy-to-install front cover, including a main body, a front cover structure is arranged on one side of the main body, the front cover structure includes a middle piece and an outer frame, and the middle piece and the outer frame are detachably connected.

[0005] By adopting the above technical solution, the main body of the suitcase is on the back which is not easy to notice, and the main part adopts a unified mold. The production of new products does not require completely re-opening the mold, but only needs to redesign the middle part and re-open the mold. It can be removed or installed from the outer frame for replacement through the detachable structure, which can not only meet consumers' demand for products of different styles, but also control costs to a certain extent and simplify the production process.

[0006] Furthermore, the outer frame is arranged on the periphery of the middle piece, the middle piece includes a flip cover and a front cover frame, the front cover frame is detachably connected to the outer frame, and the outer frame is connected to the main body through a zipper structure.

[0007] By adopting the above technical solution, the outer frame and the main body form the main frame structure of the trolley case, and the appearance of the trolley case can be changed by replacing the middle piece by oneself. The outer frame also plays a protective role and is more beautiful in appearance.

[0008] Furthermore, a snap-fit ​​structure is provided between the outer frame and the front cover frame body.

[0009] By adopting the above technical solution, positioning and assembly are facilitated.

[0010] Furthermore, the buckle structure includes a card slot and a card strip, the card slot is arranged on the front cover frame, the card strip is arranged on the inner side of the outer frame, and the card strip is adapted to the shape of the card slot.

[0011] By adopting the above technical solution, compared with the connection structure of peripherals, it is more beautiful.

[0012] Furthermore, a connecting edge is arranged on the outer periphery of the front cover frame, and screw holes are arranged at corresponding positions of the connecting edge and the outer frame and are fixed by bolts.

[0013] By adopting the above technical solution, the installation steps are simplified and effective fixation between the connecting components is achieved.

[0014] Furthermore, the flip cover and the front cover frame are connected by a zipper located in the same plane to achieve opening and closing of the front cover structure.

[0015] Compared with the traditional bag structure in which the side and bottom edges of the case cover are located in different planes and the zipper needs to make arc-shaped transitions in different planes, by adopting the above technical solution, the production process is simple and the difficulty is low, and the bag production efficiency is effectively improved.

[0016] Furthermore, the flip cover and the front cover frame are both plate-like structures with a certain thickness, which are combined to form a middle piece structure with a containing space.

[0017] Compared with the flat flip cover, by adopting the above technical solution, the connection surface between the flip cover and the front cover frame is moved back, that is, the zipper structure has a certain distance from the front of the flip cover, and the distance is the thickness of the flip cover. The zipper is not easy to be directly seen from the front, and the appearance is more beautiful.

[0018] Furthermore, the outer edge of the outer frame fits with the outer edge of the main body, the middle piece is small in size and is located inside the outer frame, and an operating space is set between the inner edge of the outer frame and the outer edge of the flip cover.

[0019] By adopting the above technical solution, it is convenient for the user to pull the zipper to open the suitcase, and at the same time, the thickness of the flap should not be too deep to avoid the need to reserve a wider operating space.

[0020] Furthermore, a wheel groove is provided at the bottom of the outer frame, and a wheel is installed in the wheel groove.

[0021] By adopting the above technical solution, compared with the structure in which all wheels are installed at the bottom of the main body, the structure is more stable and the suitcase is not easy to tip over.

[0022] Furthermore, the front cover structure is communicated with the internal accommodation space of the main body.

[0023] Compared with the prior art, the advantages of the utility model are: 1. The trolley case is produced and assembled through the outer frame and the middle piece structure respectively, so as to form a trolley case structure which is convenient for replacing and installing the front cover. Compared with the front cover of the existing two-sided flip-up suitcase, the middle piece is small in size. To change the appearance of the trolley case, it is only necessary to re-mold the middle piece part, thereby reducing the production cost; 2. It is convenient to produce trolley cases with different appearances; 3. The middle piece part and the zipper between the main body and the front cover structure are all arranged on the same plane, and the production process is simple; 4. The outer frame cooperates with the detachable middle piece to change the design of the traditional trolley case, which is beautiful in appearance, convenient and practical.
