Description

TECHNICAL FIELD

[0001] The utility model relates to a storage box, especially a storage box which can be used as a transport vehicle. BACKGROUND

[0002] In modern life and work scenes, storage and transportation needs are ubiquitous. Whether it is the arrangement and handling of household daily necessities, or the storage and transfer of goods in business activities, people expect to have a convenient and efficient tool. At present, there is a lack of products that effectively combine storage and transportation functions in the market. The existing storage and transportation tools have obvious shortcomings in function integration and use convenience. Traditional storage boxes and transportation tools are often single-function, unable to meet the requirements of goods storage and flexible transportation, and unable to meet diversified needs. Common storage boxes are mostly fixed structures, only having storage function. When moving the contents of the storage box, the contents often need to be taken out and then carried, which is a cumbersome process and can easily cause damage to the contents. If the storage box is full of miscellaneous items, it can only be dragged or carried by multiple people due to the lack of a moving device, which not only consumes physical effort but also may scratch the ground. Ordinary transport vehicles, such as trolleys, are mainly used for carrying goods and do not have a good storage space design. When carrying some scattered small items, the items are easy to scatter, which is not conducive to centralized storage and management. SUMMARY

[0003] The utility model solves the technical problem of the prior art, and provides a storage box which can be used as a transport vehicle and is convenient to move, with wheels that can be disassembled.

[0004] The utility model adopts the technical scheme that a storage box which can be used as a transport vehicle comprises a box body and wheels installed at the bottom of the box body, characterized in that a bracket is installed at the bottom of the box body, a pull rod is arranged at the front side of the box body, the wheels are disassembled and installed on the bracket, and the bottom end of the pull rod is rotationally connected to the bottom of the box body or the bracket.

[0006] In order to facilitate the clamping of the wheels into the wheel limiting groove, the elastic clamping block is wedge-shaped and gradually increases in height along the wheel sliding direction.

[0007] In order to enable the elastic clamping block to more reliably clamp the wheels, an elastic mechanism is installed at the top of the bracket, and the elastic mechanism acts on the elastic clamping block to make the elastic clamping block have a tendency to protrude towards the bottom of the bracket.

[0008] The elastic mechanism can have various structures, and preferably comprises a torsion spring, one end of the torsion spring being fixed to the bracket, and the other end of the torsion spring being fixed to the elastic clamping block.

[0009] The pull rod can have various mounting structures, and preferably, the bottom of the bracket has a mounting portion extending outward and protruding from the front side of the box body, and the bottom end of the pull rod is rotatably connected to the mounting portion.

[0010] Further preferably, the bottom end of the pull rod is rotatably connected to the mounting portion by a pin shaft. In this way, the pull rod can rotate relative to the bracket, and when the box does not move, the pull rod rotates backward to lean against the front side plate of the box body, and when the box is pulled forward, the pull rod rotates forward.

[0011] The pull rod can have various structures, and preferably comprises a lower pull rod and an upper pull rod, the lower pull rod being connected to the mounting portion, and the upper pull rod being connected to the lower pull rod and being able to extend and retract relative to the lower pull rod, and the top of the upper pull rod being provided with a handle. In this way, when the box is pulled, the upper pull rod can be pulled upward, and when the box is not pulled, the lower end of the upper pull rod can be retracted into the lower pull rod.

[0012] In order to reliably limit and fix the bracket and the box body, the left and right sides of the bracket have upwardly folded flanges, and the box body is limited between the flanges on the left and right sides and is fixed to the bracket by fasteners.

[0013] The box body can have various structures, and preferably comprises a bottom plate, a front side plate, a rear side plate, a left side plate, a right side plate, and a cover plate, the bottom plate, the front side plate, the rear side plate, the left side plate, and the right side plate being detachably connected to the respective adjacent plates, and the cover plate being rotatably connected to the rear side plate.

[0014] Compared with the prior art, the advantages of the utility model lie in that the storage box used as a transport cart is provided with a bracket at the bottom of the box body, a pull rod at the front side of the box body, and wheels that can be detachably mounted on the bracket, and the bottom end of the pull rod is rotatably connected to the bottom of the box body or the bracket, when the storage box is used as a transport cart, the articles to be transported, such as outdoor tables and chairs, can be placed in the box body, and after the wheels are mounted on the bracket, the pull rod is pulled forward to drive the box body to move forward smoothly, which is very convenient and labor-saving, and when not in use, the wheels can be detached or locked to avoid the box body from moving randomly.
