[0005] It is further characterized in that: the gantry support comprises two horizontal main beams, the two ends of the two main beams are connected and installed with the top ends of the box walls on both sides of the carriage through a connecting beam inclined downward, and the two horizontal main beams are connected by a vertical secondary beam;

[0006] The inner side of the lower end of the connecting beam is rotatably connected to one end of the rotating arm through a damping hinge, and the other end of the rotating arm is rotatably connected to the end of the multifunctional flat plate through a damping hinge;

[0007] An upper slide rail slidably connected to the upper end of the secondary beam of the gantry support is provided at the position of the mounting plate corresponding to the lower end thereof, and a lower slide rail slidably connected to the lower end of the mounting plate is also provided on the gantry support, and the lower slide rail is connected to the lower end of the connecting beam through a horizontal short crossbeam;

[0008] A positioning lock is also provided on the short crossbeam, and a locking hole matching with the lock core of the positioning lock is provided at the end of the multifunctional flat plate;

[0009] The multifunctional flat plate is composed of double-layer mounting plates, and the double-layer mounting plates are connected by aluminum profile beams distributed around them.

[0010] After adopting the above structure, multifunctional flat plates rotatably connected are provided at both ends of the gantry bracket through rotating arms. When in use, the multifunctional flat plate is folded outwardly under the drive of the rotating arm to form a horizontal platform, which is convenient to use and has high expandability and flexibility. When not in use, it is stored inside the gantry bracket. At the same time, the interior of the gantry bracket is also provided with a mounting plate that can be pushed and pulled outward, which is convenient for taking and placing mounted items, further improving the expandability and flexibility of the structure of the utility model.

[0011] Figure 1 This is a schematic diagram of the structure of the utility model installed on a cargo box;

[0012] Figure 2 It is a schematic diagram of the overall structure of the utility model;

[0013] Figure 3 It is a schematic diagram of the overall structure of the utility model (the multifunctional flat plate is folded outwards and the mounting plate is pulled outwards). DETAILED DESCRIPTION

[0014] like Figure 1 , 2 As shown, a gantry expansion platform for a truck cargo box includes a gantry bracket 1. The gantry bracket 1 includes two horizontal main beams 11. The two ends of the two horizontal main beams 11 are connected and installed to the top of the box wall of the car through a connecting beam 12 that is inclined downward. The two horizontal main beams 11 are connected by a vertical secondary beam 13. The two ends of the gantry bracket 1 are connected to a multifunctional flat plate 3 through a rotatably connected rotating arm 2. The multifunctional flat plate 3 is composed of a double-layer mounting plate. The double-layer mounting plates are connected by aluminum profiles distributed all around. The double-layer mounting plates are provided with holes for mounting items to facilitate the storage and fixation of items. Specifically, the end of the lower end of the connecting beam 12 of the gantry bracket 1 is rotatably connected to one end of the rotating arm 2 through a rotatably connected damping hinge 4, and the other end of the rotating arm 2 is rotatably connected to the end of the multifunctional flat plate 3 through the damping hinge 4. When in use, Figure 3 As shown, the multifunctional tablet 3 is folded outwards under the drive of the rotating arm 2 to form a horizontal platform, which can be used as a work surface and is also convenient for installing storage boxes or taking items. When not in use, the multifunctional tablet 3 is folded inwards under the drive of the rotating arm 2 and is then stored diagonally downward into the gantry bracket 1.

[0015] The inner sides of the gantry support 1 are also provided with mounting plates 5 that can be pushed and pulled outward in the horizontal direction. The lower end of the secondary beam 13 of the gantry support 1 is provided with an upper slide rail 131 slidably connected to the upper end thereof at the position corresponding to the mounting plate 5. The gantry support 1 is also provided with a lower slide rail 132 slidably connected to the lower end of the mounting plate 5. The lower slide rail 132 is connected to the lower end of the connecting beam 12 through a horizontal short cross beam 14. The upper slide rail 131, the lower slide rail 132 and the mounting plate 5 are arranged in coordination, so that the mounting plate 5 can be retracted into the main body of the gantry support 1 when not in use. If necessary, Figure 3 As shown, it can be pulled outward to facilitate the removal of mounted tools or other items.

[0016] In order to ensure the stability of the multifunctional flat panel 3 when it is stored in the gantry bracket 1, a positioning lock 6 is further provided on the short crossbeam 14, and the lock core of the positioning lock 6 is matched and connected with the locking hole at the lower end of the multifunctional flat panel 3, and the locking hole is a through hole inside the aluminum profile. When the multifunctional flat panel 3 is folded inwardly and stored in the gantry bracket 1 under the drive of the rotating arm 2, the lock core of the positioning lock 6 is extended into the locking hole of the multifunctional flat panel 3 to lock it, thereby ensuring the stability of the multifunctional flat panel 3.

[0017] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by anyone familiar with the technology within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
