Description

Technical Field

[0001] This utility model relates to a detachable and combinable suitcase, belonging to the field of suitcases. Background Technology

[0002] A suitcase, also known as a travel case or rolling case, is a box carried when traveling to store belongings. It is a type of luggage and is usually used to store clothing, personal care products, and souvenirs needed for a trip.

[0003] However, in actual use, since suitcases are mobile, for the sake of portability during travel, children may sit on them and push them, or heavy objects may be placed on them. The increase in overall weight requires an increase in the load-bearing capacity of the casters. Existing suitcases are all made of plastic. Some suitcases will have increased thickness at the corners or metal triangular plates, but the corners are not the key points for bearing weight, and the middle part is easy to deform.

[0004] Therefore, this utility model provides a detachable and combinable suitcase that solves the above-mentioned problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a detachable and combinable suitcase that solves the above problems.

[0006] This utility model is implemented as follows:

[0007] A detachable and combinable suitcase includes a case body that can be unfolded or opened, metal corner plates fixed to each corner of the case body, a pull rod slidably connected to the case body, and a support plate detachably mounted on the side or top of the case body.

[0008] As a further improvement, hooks and receiving slots are respectively installed at the upper and lower ends of the box, so that when the bearing plate is not in use, one end can be placed in the receiving slot and the other end can be detachably and fixedly connected to the hook.

[0009] As a further improvement, the support plate is formed by horizontally fixing a first support part, a first vertical part, and a second vertical part in sequence, and the width of the first vertical part is smaller than the width of the second vertical part, so that the second vertical part can be locked on the pull rod and contact the four corners of the first support part with the metal corner plate.

[0010] As a further improvement, the support plate is made of metal and has a thickness of .-cm.

[0011] As a further improvement, the support plate is made of aluminum alloy.

[0012] As a further improvement, the support plate is made of resin material.

[0013] As a further improvement, the hook is a trapezoidal structure with a hollow center.

[0014] As a further improvement, the hook includes a first horizontal portion and a second horizontal portion, wherein the length of the first horizontal portion is greater than the width of the second vertical portion, and the length of the second horizontal portion of the hook is equal to the width of the first vertical portion.

[0015] The beneficial effects of this utility model are as follows: The support plate of this utility model has two usage states. First, due to the metal corner plate at the top of the suitcase, the position of the metal corner plate is higher than the middle part of the suitcase. The second vertical part of the support plate passes obliquely through the middle part of the pull rod, and remains horizontal after passing through the pull rod. The four sides of the support plate are in direct contact with the metal corner plate, realizing that the middle part is suspended with the metal corner plate as the fulcrum, and the weight of people or objects is directly transferred through the metal corner plate, avoiding direct contact with the suitcase. Second, in the unused state, or when the suitcase needs to be opened or closed, the second vertical part of the support plate is engaged with the hook with the receiving groove as the support point, so that the support plate is suspended on the side of the suitcase, preventing the support plate from slipping. The above two states solve the problem that the middle part of the suitcase is easily deformed when heavy objects are placed on it. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Reference Figures 1-4 As shown, this embodiment provides a specific implementation of a detachable and combinable suitcase, including a suitcase body 10 that can be unfolded or opened, metal corner plates 20 fixed to each corner of the suitcase body 10, a pull rod 30 slidably connected to the suitcase body 10, and a support plate 40 detachably installed on the side or top of the suitcase body 10.

[0025] In this embodiment, hooks 101 and receiving grooves 102 are respectively installed at the upper and lower ends of the box body 10, so that the support plate 40 can be placed in the receiving groove 102 at one end when not in use, and the other end can be detachably and fixedly connected to the hooks 101.

[0026] In this embodiment, the support plate 40 is formed by horizontally fixing a first support portion 401, a first vertical portion 402, and a second vertical portion 403 in sequence. The width of the first vertical portion 402 is smaller than the width of the second vertical portion 403, so that the second vertical portion 403 can be locked onto the pull rod 30 and contact the four corners of the first support portion 401 with the metal corner plate 20.

[0027] Based on the above technical solutions, the bearing plate 40 of this utility model has two usage states. First, due to the metal corner plate 20, the top of the box 10 is positioned higher than the middle part of the box 10. The second vertical part 403 of the bearing plate 40 passes through the middle part of the pull rod 30 at an angle. After passing through the pull rod 30, it remains horizontal. The four sides of the bearing plate 40 are in direct contact with the metal corner plate 20, so that the middle position is suspended with the metal corner plate 20 as the fulcrum. The impact of people or objects is directly transmitted through the metal corner plate 20, avoiding direct contact with the box 10.

[0028] Second, when not in use, or when the box 10 needs to be opened or closed, the second vertical part 403 of the support plate 40 is engaged with the hook 101 using the receiving groove 102 as the support point, so as to suspend the support plate 40 on the side of the box 10 and prevent the support plate 40 from slipping.

[0029] The two states described above solve the problem of heavy objects pressing on a suitcase, causing the middle part of the suitcase to easily deform.

[0030] In this embodiment, the bearing plate 40 is made of metal material and has a thickness of 0.3-1cm; it is not easily deformed and has good load-bearing capacity.

[0031] Furthermore, the bearing plate 40 is made of aluminum alloy. The core advantages of aluminum alloy are its lightweight and high strength, corrosion resistance, excellent processing performance, good electrical and thermal conductivity, environmental friendliness and recyclability. The key point is that it also has a certain degree of rigidity while ensuring a low height.

[0032] In other embodiments, the support plate 40 is made of resin material, particularly thermosetting resin material, which is a high molecular polymer material. The molecular chains are chemically cross-linked to form a rigid three-dimensional network structure, giving it excellent comprehensive properties, including high strength, good heat resistance, excellent electrical properties, corrosion resistance, aging resistance, good dimensional stability, etc. It is easy to process and has extremely low cost.

[0033] In this embodiment, the hook 101 is a trapezoidal structure with a hollow center.

[0034] Furthermore, the hook 101 includes a first horizontal portion 111 and a second horizontal portion 112, and the length of the first horizontal portion 111 is greater than the width of the second vertical portion 403, while the length of the second horizontal portion 112 of the hook is equal to the width of the first vertical portion 402.

[0035] In the above technical solution, after the trapezoidal hook 101 is engaged with the vertical part of the support plate 40, the support plate 40 is fixed by its own weight and the hook 101 hanging down. After the support plate 40 touches the receiving groove 102, it is not easy to detach without the action of external force.

[0036] In this embodiment, the cross-sectional shape of the receiving groove 102 is semi-circular, which directly restricts movement after the bearing plate 40 and the receiving groove 102 are fitted together.

[0037] In this embodiment, the inner diameter of the receiving groove 102 is 0.4-1.2cm, which is similar to the thickness of the support plate 40, ensuring that the support plate 40 can be embedded in the receiving groove 102.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
