Description

Technical Field

[0001] The utility model relates to the technical field of hinge structures, in particular to a luggage hinge structure that does not damage a zipper. Background Art

[0002] A suitcase usually includes two upper and lower boxes, which can be connected by a zipper or an aluminum frame. For aluminum-frame suitcases, the upper and lower boxes are connected by two hinge devices, which can be opened and closed. Existing hinge devices generally need to be installed on the outer surface of the suitcase, which not only affects the aesthetics, but also easily causes the hinge blades to bump into each other. If the hinge blades and hinge shafts are all set inside the suitcase, two shafts are required to connect the two hinge blades respectively. The structure is complicated and will increase the thickness of the hinge device, which also affects the aesthetics and will occupy more storage space inside the suitcase. In addition, existing aluminum-frame suitcases usually need to use steel nails to connect the frame and the box body. The process is relatively complicated and increases the overall weight of the suitcase.

[0003] In addition, with the existing single-piece hinge structure, when the suitcase is opened, the middle part of the hinge bulges and deforms toward the zipper until it interferes with the zipper, which can easily cause the zipper to burst and open the suitcase, or be squeezed, deformed and damaged.

[0004] There is a need for a new type of luggage hinge structure that can solve the above-mentioned problems. Utility Model Content

[0005] The utility model provides a luggage hinge structure which does not damage a zipper. By technically transforming the existing luggage hinge structure, the problem that the existing luggage hinge is prone to bumping and squeezing the zipper during use is solved.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A luggage hinge structure that does not damage a zipper includes a hinge body, the hinge body including a left end portion and a right end portion, and mounting studs protruding from both ends of the hinge body toward a mounting surface of the luggage. The hinge body is fixedly mounted on an upper cover and a lower cover of the luggage via the mounting studs. The junction of the left and right end portions in the middle of the hinge body is arranged directly opposite the luggage zipper, and an arc-shaped zipper protection groove is provided in the middle of the hinge body, which is recessed inwardly on one side relative to the luggage, and the zipper protection groove surrounds the outer periphery of the zipper.

[0008] Preferably, a mounting cover is provided on the inner side of the luggage case, and the mounting studs of the hinge body pass through the luggage case and are fixedly connected to the mounting cover.

[0009] Preferably, a first buffer slot is provided on the left and right sides of the zipper protection slot, the first buffer slot is located on the side of the hinge body opposite to the suitcase, and the upper edge of the first buffer slot is continuously arranged with the upper edge of the zipper protection slot.

[0010] Preferably, an inner groove wall of the first buffer groove on a side opposite to the zipper protection groove is provided with an inclined surface, and the inclined surface is arranged obliquely upward from the groove bottom to the groove opening.

[0011] Preferably, a second buffer slot is provided on a side of the hinge body facing away from the suitcase, there are two second buffer slots, and the second buffer slots are provided at the back side of the connection between the first buffer slot and the zipper protection slot.

[0012] Preferably, the second buffer slot is a trapezoidal slot.

[0013] Preferably, the hinge body is provided in one piece, and the hinge body is installed in the middle position of one side of the suitcase.

[0014] Preferably, the number of the hinge bodies is two, and the hinge bodies are installed at the upper and lower ends of one side of the luggage case.

[0015] The beneficial effects of the present invention are:

[0016] The two ends of the hinge structure of the utility model are fixedly connected to the upper cover and the lower cover of the suitcase respectively. The hinge structure is provided with an arc-shaped zipper protection groove on the side opposite to the zipper of the suitcase, and the first buffer groove and the second buffer groove are provided on both sides and the back of the zipper protection groove for buffering and releasing bending stress. When the suitcase is opened and the hinge structure bends, the middle part is concave inward, so that the arc-shaped zipper protection groove surrounds the outside of the suitcase zipper, and the hinge structure will not collide with the zipper, causing the zipper to break or be damaged.

[0025] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0026] Figure 1 This is a schematic diagram of the existing luggage hinge structure when it is bent. It can be seen that when the luggage hinge structure is bent, the middle part will bulge outward, pressing against the zipper part, causing the zipper to break.

[0027] See Figure 2-7 As shown, the utility model provides a luggage hinge structure that does not damage the zipper 7, including a hinge body 1, the hinge body 1 including a left end portion 11 and a right end portion 12, and mounting studs 2 are provided at both ends of the hinge body 1 protruding toward the mounting surface of the luggage. The hinge body 1 is fixedly mounted on the upper cover and the lower cover of the luggage by the mounting studs 2, and the connection between the left end portion 11 and the right end portion 12 in the middle position of the hinge body 1 is arranged opposite to the luggage zipper 7, and an arc-shaped zipper protection groove 3 is provided inwardly on one side of the luggage at the middle position of the hinge body 1, and the zipper protection groove 3 is surrounded by the outer peripheral side of the zipper 7.

[0028] Furthermore, in order to fix the hinge body 1 on the suitcase, a mounting cover 4 is provided on the inner side of the suitcase, and the mounting studs 2 of the hinge body 1 pass through the suitcase and are fixedly connected to the mounting cover 4.

[0029] Furthermore, in order to make the bending of the hinge body 1 more labor-saving, a first buffer slot 5 is opened on the left and right sides of the zipper protection slot 3. The first buffer slot 5 is located on the side of the hinge body 1 opposite to the suitcase, and the upper edge of the first buffer slot 5 is continuously arranged with the upper edge of the zipper protection slot 3.

[0030] Furthermore, an inclined surface 51 is provided on the inner groove wall of the first buffer groove 5 on the side opposite to the zipper protection groove 3 , and the inclined surface 51 is provided obliquely upward from the groove bottom to the groove opening.

[0031] Furthermore, in order to ensure that the zipper protection groove 3 is recessed inward when the hinge body 1 is bent, and does not protrude outward to press against the zipper 7, a second buffer groove 6 is provided on the side of the hinge body 1 facing away from the suitcase. There are two second buffer grooves 6, and the second buffer grooves 6 are provided on the back side of the connection between the first buffer groove 5 and the zipper protection groove 3.

[0032] Furthermore, the second buffer slot 6 is a trapezoidal slot.

[0033] Furthermore, in a specific embodiment 2, for a smaller suitcase, the hinge body 1 is provided as one, and the hinge body 1 is installed in the middle position of one side of the suitcase.

[0034] Furthermore, in a specific embodiment 3, for a larger suitcase, two hinge bodies 1 are provided, and the hinge bodies 1 are installed at the upper and lower ends of one side of the suitcase.

[0035] The two ends of the hinge structure of this embodiment are fixedly connected to the upper cover and the lower cover of the suitcase respectively. A curved zipper protection groove is provided on the side of the hinge structure opposite to the suitcase zipper, and a first buffer groove and a second buffer groove are provided on both sides and the back of the zipper protection groove for buffering and releasing bending stress. When the suitcase is opened and the hinge structure bends, the middle part is concave inward, so that the curved zipper protection groove surrounds the outside of the suitcase zipper, and the hinge structure does not collide with the zipper and cause damage to the zipper.
