Description

Technical Field

[0001] The present invention relates to the technical field of transportation devices, and more specifically, to a transportation device that is convenient for storage. Background Art

[0002] During the transportation of trusses, truss transportation devices are often used. Most of the existing truss transportation devices are fixed-structured trolleys that cannot be disassembled, and they are relatively large in volume, occupying a large amount of space, which is not convenient for the storage of idle trolleys and not convenient for users to transport and carry. Summary of the Invention

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a transportation device that is convenient for storage, with a simple structure, easy to disassemble and install, and can effectively save space when being stored.

[0004] To solve the above problems, the technical solution adopted by the present invention is: a transportation device that is convenient for storage, including two relatively arranged side support groups and a four-headed connector located between the two side support groups;

[0005] Each of the side support groups includes a main bar, a side bar, a first vertical bar, a second vertical bar, a first connecting bar, a second connecting bar, a third connecting bar, an armrest bar, casters, a first connector, a second connector, and a third connector;

[0006] The armrest bar is rotatably connected to the upper side of the main bar through the third connector, and during the rotation of the armrest bar, it is always in the same vertical plane as the main bar;

[0007] The first vertical bar and the second vertical bar are perpendicularly connected to the lower side of the main bar, both ends of the side bar are respectively connected to one end of the first vertical bar away from the main bar and one end of the second vertical bar away from the main bar, and the two casters are installed at both ends of the main bar;

[0008] One end of each of the second connecting bar and the third connecting bar is provided with a perpendicular sleeve, the sleeve of the second connecting bar is rotatably sleeved on the first vertical bar, and the sleeve of the third connecting bar is rotatably sleeved on the second vertical bar;

[0009] On the opposite sides of the two side support groups, the first connector and the second connector are respectively arranged at both ends of the main bar. The first connecting bar is rotatably connected to one end of the main bar through the first connector, and during the rotation of the first connecting bar, it is always in the same horizontal plane as the main bar;

[0010] One end of the second connecting rod and the third connecting rod of the two side bracket groups, which are far away from the sleeve, are detachably connected to the four-way connector, and one end of the first connecting rod of one of the side bracket groups, which is far away from the first connector, is detachably connected to the second connector of the other side bracket group.

[0011] When the portable transportation device needs to be used, first place the two side bracket groups in a folded state opposite to each other, then connect the first connecting rod on one of the side bracket groups to the second connector of the other side bracket group, and then connect the first connecting rod on the other side bracket group to the second connector of the relatively arranged side bracket group. Then connect the second connecting rod and the third connecting rod on the two side bracket groups to the four-way connector respectively. Finally, rotate the handrail bars on the two side bracket groups to form a 90° angle with the main rod to complete the assembly of the transportation device in the use state.

[0012] When the portable transportation device is no longer in use, directly disconnect the connection between the first connecting rod on each side bracket group and the corresponding second connector, and the connection between the second and third connecting rods and the four-way connector, then the transportation device can be quickly disassembled into two side bracket groups and a four-way connector, and all the components on each side bracket group can be folded and stored, greatly reducing the space occupied and facilitating the storage of the transportation device.

[0013] Further, the number of handrail bars on each side bracket group is two, and they are respectively arranged at both ends of the main rod. On the one hand, it provides handrails for users to push the transportation device; on the other hand, when the handrail bars are in the use state, they can form guardrails to prevent the truss from falling during transportation.

[0014] Further, the distance between the two third connectors is greater than the sum of the lengths of the two handrail bars. When the handrail bars are in the storage state, they can be parallel and close to the main rod, reducing the space occupied.

[0015] Further, the length of the side rod is greater than the sum of the lengths of the second connecting rod and the third connecting rod. When the second connecting rod and the third connecting rod are in the storage state, they can be stored between the main rod and the side rod, reducing the space occupied.

[0016] Further, the side bracket group further includes a force-sharing rod, and both ends of the force-sharing rod are connected to the main force rod and the side rod respectively, and are parallel to the first vertical rod and the second vertical rod. This can prevent the side rod from being deformed due to excessive force and breaking during transportation.

[0017] Further, connection pipes adapted to cooperate with other transportation devices are respectively provided at both ends of the main bar, which can be connected to other transportation devices to increase the transportation volume.

[0018] Further, the connection pipe is provided with a pin hole penetrating through the side wall. A pin can be inserted through the pin hole to fix the connector inserted into the connection pipe.

[0019] Further, the four - head connector includes a communication pipe and four connectors located in the same plane as the communication pipe. Two of the connectors are respectively arranged at both ends of the communication pipe, and the two connectors form an angle of 90°. On the one hand, the two side support groups are connected; on the other hand, when the transportation device is in use, a base is provided.

[0020] Further, the first connector and the second connector are clamping members, and clamping pieces matching the installation grooves are provided at both ends of the first connecting bar, enabling the first connecting rod to rotate freely around the first connector.

[0021] Further, the third connector is a movable hinge, which includes an upper hinge and a lower hinge. The upper hinge is connected to the end of the handrail bar, and the lower hinge is connected to the main bar, enabling the maximum movement range of the handrail bar to be 90°, forming a guardrail that can prevent the truss from falling.
