DETAILED DESCRIPTION

[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model. Example

[0021] See also Figure 1-4, the utility model provides a technical solution: a flatbed truck for construction;

[0022] This case aims to provide a construction flatbed truck that is conducive to the transportation of construction materials. The existing flatbed trucks have a fixed structure and cannot be adjusted according to the size of the construction materials, which can easily cause damage to the construction materials.

[0023] Based on the above problems, the components in this case include a main body 1, four universal wheels 2 are installed at the bottom of the main body 1, a support frame 3 is arranged on the upper side of the main body 1, and an expansion structure is arranged on the upper side of the main body 1, and the expansion structure includes:

[0024] A rotating shaft 4, two first bearing seats 5, a first conical tooth 6, two screw rods 7, two second conical teeth 8, two second bearing seats 9, two support plates 10, two expansion frames 11 and two moving blocks 12;

[0025] Two first bearing seats 5 are arranged on the top of the main body 1, the rotating shaft 4 is connected to the two first bearing seats 5, the first conical teeth 6 are arranged in the middle part of the rotating shaft 4, the two second bearing seats 9 are arranged on the top of the main body 1, the two support plates 10 are installed on the top of the main body 1, one side of the two screw rods 7 is rotatably connected to the two second bearing seats 9, and the other end is connected to the inner side of the two support plates 10 through bearings, the two second conical teeth 8 are connected to one end of the two screw rods 7, the two moving blocks 12 are threadedly connected to the two screw rods 7, and the bottom of the two expansion frames 11 is connected to the top of the two moving blocks 12;

[0026] It should be noted that, during the transportation of building materials, especially boards, the operator can rotate the rotating shaft 4. At this time, the first conical teeth 6 cooperate with the two second conical teeth 8 to drive the two screws 7 to rotate, and then the two expansion frames 11 can be driven to extend from the bottom of the support frame 3 through the two moving blocks 12. The two support plates 10 are used to provide support force for the two expansion frames 11, thereby increasing the stability of the expansion frame 11. The two first bearing seats 5 and the two second bearing seats 9 are used to provide stable support force for the rotating shaft 4 and the screw 7 to prevent the rotating shaft 4 and the screw 7 from shaking. Finally, with the universal wheel 2 and the handrail 14, the purpose of transporting and moving building boards of different sizes can be achieved;

[0027] It should be emphasized that the expansion rack 11 is set to be L-shaped as a whole, and after the building board is placed on the top of the flatbed truck, it can block and protect both sides of the board to prevent the board from slipping or being hit by external force during the board transportation process, thereby increasing the transportation effect of the building board;

[0028] Since the surface of the rotating shaft 4 is smooth, a hand wheel 13 is provided at one end of the rotating shaft 4 to facilitate the operator to rotate the rotating shaft 4;

[0029] Four slide grooves are arranged on the top of the support plate 10, and the bottom of the expansion frame 11 is slidably connected to the slide grooves, which can increase the smoothness of the overall movement of the expansion frame 11 and prevent excessive friction between the bottom of the expansion frame 11 and the top of the support plate 10, making it inconvenient for operators to adjust;

[0030] A support wheel 15 is provided on the upper side of the expansion frame 11 , which can cooperate with the support frame 3 to provide support force for one side of the expansion frame 11 , thereby further increasing the stability of the expansion frame 11 .

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
