The folding assembly 4 further includes a mounting arm 407, a cross bar 408, a slider 409, and a screw 410. The mounting arm 407 and the cross bar 408 are movably inserted. A threaded hole 411 is opened at the position where the mounting arm 407 and the cross bar 408 are movably inserted. A screw 410 is threadedly connected in the threaded hole 411. Sliders 409 are arranged at one ends of the rear end faces of the mounting arm 407 and the cross bar 408 away from the movably inserted position. Rectangular grooves 201 are symmetrically opened above one end of the load-carrying rack 2 away from the pull rod 1, and a portable loading and unloading mechanism 5 is arranged in the rectangular grooves 201.
[0020] Both bottoms of the protection plates 405 are rotatably connected to the through holes 403 through rotating shafts. One ends of the sliders 409 are rotatably connected to the mounting arm 407 through rotating seats, and the other ends of the sliders 409 are slidably connected in the sliding grooves 406. By setting the bottoms of the protection plates 405 to be rotatably connected to the through holes 403 through rotating shafts and with the sliding cooperation of the sliders 409 and the sliding grooves 406, it is convenient to store the protection plates 405 in the storage grooves 402, playing a protective role for the protection plates 405 and reducing the occupied area.
[0021] The portable loading and unloading mechanism 5 includes a reversible motor 501, a driving wheel 502, a driven wheel 504 and a protective cover 507. The protective cover 507 is fixedly arranged on the front end face of the load-carrying rack 2. The reversible motor 501 is fixedly arranged inside the protective cover 507. The output shaft of the reversible motor 501 is coaxially connected with the driving wheel 502. A rotating column 503 is arranged on one side of the reversible motor 501. The rotating column 503 penetrates through the protective cover 507 and is rotatably connected inside the load-carrying rack 2. A driven wheel 504 is fixedly connected to the rotating column 503 inside the protective cover 507. The driven wheel 504 is meshed and connected with the driving wheel 502. The portable loading and unloading mechanism 5 further includes a bearing plate 505 and rollers 506. Bearing plates 505 are fixedly connected to the outer walls of the rotating columns 503 at positions corresponding to the rectangular grooves 201. Rollers 506 are arranged on the surfaces of the bearing plates 505, and the rollers 506 are linearly distributed.
[0022] The inner wall width of the rectangular groove 201 is adapted to the outer wall width of the bearing plate 505; by setting the outer wall width of the bearing plate 505 to be adapted to the inner wall width of the rectangular groove 201, it is convenient to store the bearing plate 505 in the rectangular groove 201, further reducing the occupied area.
[0023] Anti-slip textures are arranged on the outer wall of the rotating sleeve 301, and the anti-slip textures are made of anti-slip rubber material; by setting the rotating sleeve 301 with anti-slip textures and made of anti-slip rubber material, it enables the user to better adjust the adjusting component 3, thus facilitating the adjustment of the protective plate 405 to adapt to goods of different widths.
[0024] The working principle of the present utility model: Firstly, when the load-carrying trays at the use site are in short supply, the reversible motor 501 is started to drive the coaxially connected driving wheel 502 to rotate, driving the meshed driven wheel 504 to rotate, and then driving the rotating column 503 to rotate, so as to rotate the bearing plate 505 fixedly connected to the rotating column 503 out of the rectangular groove 201 and place it on the ground. With the cooperation of the rollers 506, the goods can be moved from the bearing plate 505 to the load-carrying rack 2, reducing the labor intensity of the user. The adjusting component 3 is adjusted according to the width of the goods. The rotating sleeve 301 is rotated to drive the threaded rod 302 to rotate, so that the movable block 303 on the threaded rod 302 moves horizontally, and then drives the connecting rod 304 fixedly connected thereto to horizontally expand and contract, for adjusting the folding component 4 to protect the goods from left and right. After adjusting to the appropriate position, the goods are completely pushed into the load-carrying rack 2, reducing the risk of the goods tipping over during transportation turning. Immediately after the goods are transported and not needed, the screw 410 in the screw hole 411 is removed, and the installation arm 407 and the cross bar 408 are pulled to drive the sliding block 409 rotatably connected thereto to slide down in the sliding groove 406. At this time, the cross bar 408 will also contract inside the installation arm 407, so that the symmetrical protective plates 405 are folded in the storage groove 402, finally completing the folding work of the folding component 4, which is convenient and fast.
