Description

Technical Field

[0001] The utility model relates to a case cover, in particular to a case cover of a luggage case. Background Art

[0002] At present, the trunk cover of a suitcase is mainly composed of structures such as a door panel, a frame and a plurality of hinges. The frame is a complete rectangular frame. The rectangular door panel is first placed in the frame, and the two are assembled and snapped into place so that the frame is completely covered on the outer circumference of the door panel. Then, a plurality of rivets are used to rivet between the frame and the door panel, and then a plurality of hinges are riveted to the frame in sequence through a plurality of rivets. Obviously, according to the above manufacturing structure, the installation of the door panel and the frame needs to go through the process of assembling and snapping into place and riveting with a plurality of rivets. Therefore, for the door panel, The assembly structure with the frame has high requirements. Once there is a size error between the two, the frame cannot be accurately wrapped around the door panel. The use of multiple rivets also adds many riveting processes, which can easily increase production costs and reduce production efficiency. The appearance of the box cover appears quite ugly due to the presence of multiple riveting marks. At the same time, several hinges usually use combined components, which are installed on the frame in turn, which not only complicates the manufacturing process, but also makes it difficult to ensure the installation size, which brings inconvenience to the subsequent connection and assembly of the box cover and the box body. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a suitcase cover which can simplify the production process, reduce the production cost, improve the production efficiency, reduce the manufacturing process and ensure the assembly accuracy, and can make the appearance more beautiful.

[0004] The technical problem of the utility model is achieved through the following technical solutions:

[0005] A trunk cover of a suitcase comprises a door panel, a frame and a plurality of hinges. The outer circumference of the door panel is provided with a peripheral edge, the frame is arranged in the door panel and is fixed by folding the peripheral edge inward and fastening it to the frame. The plurality of hinges are simultaneously installed on a mounting strip and riveted to the frame by the mounting strip, thereby forming a plurality of hinges that are simultaneously installed on the frame.

[0006] The outer circumference of the frame is provided with a circle of embedding grooves, and the surrounding edge is folded inwards and fastened in the embedding grooves of the frame to be fixed.

[0025] The embodiments of the present invention will be described in detail below according to the above-mentioned drawings.

[0026] like Figure 1 to Figure 9 As shown, 1. door panel, 11. surrounding edge, 12. ring groove, 13. installation notch, 2. frame, 20. fracture, 21. embedded groove, 22. outer groove wall, 23. clamping protrusion, 3. hinge, 31. hinge axis, 4. installation strip, 41. clamping groove, 5. hinge seat, 6. rivet hole.

[0027] A luggage cover can be closed with a luggage body, and its structure is as follows Figure 1 As shown, it is mainly composed of a door panel 1, a frame 2 and a plurality of hinges 3.

[0028] The door panel 1 is a rectangular panel, and a surrounding edge 11 is provided around the outer circumference of the door panel 1. The door panel 1 and the surrounding edge 11 on the outer circumference form a box-shaped component with an upper opening.

[0029] The corresponding frame 2 is a rectangular frame that matches the shape of the door panel 1, so the frame 2 can be set just inside the door panel 1. Usually, a rectangular annular groove 12 formed by a circle of surrounding edge 11 is provided on the surface of the door panel 1, that is, on the box-shaped inner bottom surface. Then, the frame 2 will be fitted in the annular groove 12 of the door panel 1, which plays a certain installation and positioning role. The surrounding edge 11 is then folded inward and fastened to the frame 2 to form a fixation. The specific structure is: a circle of embedding grooves 21 is provided on the outer circumference of the frame 2, and the cross-section of the outer groove wall 22 of the embedding groove is arc-shaped. The surrounding edge 11 is folded inward and covers the outer groove wall 22 in a "C" shape, and then it can be fastened in the embedding groove 21 of the frame 2 to form a fixation. The use of this fastening structure can ensure the tightness of the connection between the door panel 1 and the frame 2.

[0030] Obviously, this fixing structure in which the frame 2 is built into the door panel 1 and the surrounding edge 11 is folded and tightened in the embedding groove 21, compared with the traditional frame 2 that wraps the outer circumference of the door panel 1 and is riveted with multiple rivets, greatly reduces the assembly structure requirements of the door panel 1 and the frame 2. Even if there are some dimensional errors between the two, they can be fixed by adjusting the surrounding edge 11. The production process is simpler, especially the riveting process of rivets is saved, and the production cost can be reduced and the production efficiency can be improved. In addition, the appearance of the box cover is complete and integrated, and it looks more beautiful.

[0031] The plurality of hinges 3 are simultaneously mounted on a mounting strip 4. For example, two hinges are designed in this embodiment. Each hinge 3 is an integrally bent "bow"-shaped member. A hinge shaft 31 is provided at the rear end of each hinge 3, and a hinge seat 5 at a corresponding position is provided on the mounting strip 4. Therefore, each hinge 3 is hingedly mounted on the corresponding hinge seat 5 via the hinge shaft 31 to form rotation.

[0032] Then, the mounting strip 4 is directly riveted to the frame 2 , so that a plurality of hinges 3 can be mounted on the frame 2 at the same time.

[0033] The riveting structure of the mounting strip 4 on the frame 2 is as follows: a circle of protrusions 23 are provided on the top of the frame 2, and a corresponding groove 41 is provided on the side of the mounting strip 4. The mounting strip 4 is first mounted on the protrusions 23 through the groove 41, and then riveted to the protrusions 23 through a plurality of rivet holes 6 on the mounting strip 4.

[0034] Since this installation structure does not require the sequential installation of several hinges 3, it can also improve production efficiency, ensure the accuracy of installation dimensions, and facilitate the subsequent connection and assembly of the box cover and the box body; of course, the hinge 3 adopts a unique one-piece molded component, which is simpler and more convenient to install than the traditional combined hinge.

[0035] In addition, one of the rectangular sides of the frame 2, as in the present embodiment, is provided with a break 20 at the short side of the rectangle. The purpose of designing the break is to appropriately adjust the fitting distance between the frame 2 and the surrounding edge 11 when an error occurs in the assembly size, so as to facilitate the subsequent folding and tightening of the surrounding edge 11 to the frame 2. An installation notch 13 is provided on the surrounding edge 11 of the door panel 1 adjacent to the break 20.

[0036] Then, the mounting strip 4 will be set at the break 20 of the frame 2, and the two ends of the mounting strip 4 will be respectively engaged with the clamping protrusions 23 of the frame 2 on both sides of the break 20 through the clamping grooves 41 and riveted to install, and the several hinges 3 on the mounting strip 4 will just extend out of the door panel 1 from the mounting notch 13, so as to facilitate the connection with the box body of the suitcase.

[0037] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
