Description

Technical Field

[0001] The utility model relates to the technical field of trolley cases, in particular to a multifunctional sit-on trolley case. Background Art

[0002] A luggage case, also known as a travel case or a trolley case, is a box used to place items when going out. It is one type of luggage. Usually, a luggage case is used to place clothes, personal care products and souvenirs needed during a journey. Currently, the luggage cases on the market only have the function of carrying luggage. When people go out with children, it is often very inconvenient. Sometimes, they have to carry an additional folding cart for children, which brings inconvenience to their travel.

[0003] Therefore, multifunctional sit-on trolley cases have emerged on the market to replace ordinary luggage cases. Considering the functions of the trolley case, the connection and combination structure of the box body and the frame is an important part. Currently, in general connection structures of the box body and the frame, the locking mechanism is basically set on the seat board of the frame. Such a design is rather cumbersome in operation. If a child is sitting on the seat board, the child needs to be moved away from the seat board to combine and separate the box body and the frame, which is inconvenient for traveling while carrying a child and luggage at the same time. Summary of the Invention

[0004] The purpose of the utility model is to provide a multifunctional sit-on trolley case to solve one or more problems of the prior art.

[0005] The utility model is realized as follows: A multifunctional sit-on trolley case includes a box body, a frame, a seat board, a locking assembly, a handlebar, a front wheel assembly, and a rear wheel assembly. The box body is detachably connected to the frame and is used for loading travel items.

[0006] The seat board is fixed in the middle of the frame and is used for children to sit on.

[0007] The locking assembly is installed on the box body, and by operating the locking assembly, the combination and separation of the box body and the frame are realized.

[0008] Furthermore, the upper part of the box body is rotatably connected to the locking assembly, and an n-shaped groove of the box body is provided at the lower part of the box body.

[0009] The frame is composed of a front support rod assembly, a telescopic rod assembly, and a rear support assembly. The seat board is fixed on the upper part of the front support rod assembly, and a cross bar assembly is fixed at the lower part of the front support rod assembly.

[0010] A locking groove is provided on the seat board.

[0011] The box body is installed on the cross bar assembly through the n-shaped groove of the box body, and the box body can rotate around the cross bar assembly.

[0012] When the box body rotates around the cross bar assembly so that the locking assembly on the box body engages with the locking groove on the seat plate, the box body is locked to the vehicle frame; when the locking assembly is operated to disengage from the locking groove, the box body is unlocked from the vehicle frame.

[0013] Further, the rear support assembly is rotatably connected to the seat plate or the rear support assembly is rotatably connected to the front support rod assembly.

[0014] Further, a spring is provided between the locking assembly and the box body. One end of the spring abuts against the box body, and the other end abuts against the locking assembly. When the locking assembly is operated, the spring contracts, causing the locking assembly to disengage from the locking groove to achieve unlocking; when engaging, the locking assembly automatically enters the locking groove.

[0015] Further, one end of the locking assembly inserted into the locking groove is provided with an obliquely arranged guiding surface.

[0016] Further, a rear wheel assembly is provided at the lower end of the rear support assembly, and front wheel assemblies are provided at both ends of the cross bar assembly.

[0017] Further, the telescopic pull rod assembly includes a middle telescopic tube assembly and a small telescopic tube assembly. The middle telescopic tube assembly is sleeved on the front support rod assembly and can slide telescopically, and the small telescopic tube assembly is sleeved on the middle telescopic tube assembly and can slide telescopically.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] In the present utility model, by arranging the locking assembly on the box body and operating the locking assembly, the combination and separation of the box body and the seat plate are realized, and further the combination and separation of the box body and the vehicle frame are realized. The user can use the box body and the vehicle frame separately or in combination according to needs, achieving multiple uses of one object. By operating the locking assembly, both hands can be liberated, realizing single-handed operation, which is simpler and more labor-saving. On the other hand, by arranging the locking assembly on the box body, when a child sits on the seat plate, operating the locking assembly can realize the combination and separation of the box body and the vehicle frame without moving the child, facilitating travel when carrying a child and luggage at the same time.
