For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific situations.

[0028] As Figures 1-3 shown, a double-beam wing-opening carriage body structure for a freight truck proposed by the present utility model includes a bottom plate 1 and a group of support frames 2 fixedly connected to the bottom plate 1. The upper end of the support frame 2 is fixedly connected with a top plate 3. A group of cross beams 4 are fixedly connected to the support frame 2 and are located on both sides of the top plate 3. Two wing plates 5 are hinged to the two cross beams 4 respectively. Two sets of oil cylinders 8 are arranged between the two wing plates 5 and the support frame 2.

[0029] It should be noted that grooves 10 for supporting the oil cylinders 8 are provided on both the front and rear sides of the support frame 2. One end of the oil cylinder 8 is hinged to the inner side of the groove 10, and its output end is hinged to the inner side of the wing plate 5, so that the oil cylinder 8 located in the groove 10 is used to push the wing plate 5 to unfold and contract and close.

[0030] In the present utility model, a rear door plate 7 is hinged to the front support frame 2 through a hinge, and a side plate 9 is fixedly connected to the rear support frame 2, so that the whole carriage forms a closed shape.

[0031] In an optional embodiment, two sets of locking members 6 are provided on both sides of the two wing plates 5 and the bottom plate 1;

[0032] The locking member 6 includes a connecting ring 61 fixedly connected to the side of the wing plate 5. Support rings 62 are fixedly connected to both sides of the bottom plate 1. A sliding rod 63 is slidably connected to the inner side of the support ring 62. A plug rod 64 is fixedly connected to the sliding rod 63. Support blocks 65 for supporting the sliding rod 63 are fixedly connected to both sides of the bottom plate 1.

[0033] It should be noted that the number of the support rings 62 is several, and several support rings 62 are symmetrically distributed on one side and the other side of the bottom plate 1, and the two sliding rods 63 are stably supported by the support rings 62 on both sides of the bottom plate 1.

[0034] Among them, the number of the plug rods 64 is several, and several plug rods 64 are equidistantly distributed on the sliding rod 63. The number and orientation of the connecting rings 61 correspond to the orientation and number of the plug rods 64. Through the plugging and matching of the connecting rings 61 and the plug rods 64 with corresponding numbers and orientations, the closed wing plates 5 are locked and limited.

[0035] In addition, the insertion rod 64 is L-shaped, enabling the moving insertion rod 64 to pass through the connecting ring 61. The support block 65 is U-shaped, and one end of the sliding rod 63 located inside the support block 65 is L-shaped, facilitating the user to push the sliding rod 63 to slide on the support block 65. The end of the sliding rod 63 away from the support block 65 is T-shaped, ensuring that the sliding rod 63 does not separate from the leftmost support ring 62 during the pulling process.

[0036] In this embodiment, when the wing plate 5 contracts and closes, the insertion rod 64 is driven to pass through the connecting ring 61 by pushing the sliding rod 63, thereby locking the wing plate 5 to prevent the wing plate 5 from loosening due to the squeezing of the goods during transportation.

[0037] In an alternative embodiment, a limiting member for limiting the end of the sliding rod 63 is provided on the support block 65. The limiting member includes a pull rod 67 that penetrates and is slidably connected to the support block 65. A stop block 68 is fixedly connected to the pull rod 67.

[0038] It should be noted that a rotation groove 66 for the sliding rod 63 to rotate is provided on the side of the support block 65 away from the pull rod 67. After the sliding rod 63 is pulled to align with the rotation groove 66, the sliding rod 63 can have a rotation space through the rotation groove 66. The pull rod 67 is U-shaped, and the lower end of the pull rod 67 penetrating the support block 65 penetrates the support block 65, and a rubber ring is provided at one end of the pull rod 67 penetrating the support block 65 to increase the damping when the end of the pull rod 67 penetrating the support block 65 limits the sliding rod 63.

[0039] In this embodiment, by pulling the pull rod 67 to block the end of the sliding rod 63, the sliding rod 63 can be limited. Conversely, by pulling the pull rod 67, the sliding rod 63 can be pushed, pulled, and rotated, thereby improving the convenience of the entire locking member 6 during use.

[0040] The working principle of the above embodiment is as follows: Since a set of cross beams 4 are provided on both sides of the top plate 3 to support the wing plate 5, that is, the width between the top of the wing plate 5 and the cross beam 4 is shortened, making the top space required for the oil cylinder 8 to push the wing plate 5 to unfold smaller. After the wing plate 5 contracts and closes, after rotating the sliding rod 63 to make the insertion rod 64 on the sliding rod 63 parallel to the connecting ring 61 on the wing plate 5, the pull rod 67 can be pulled, and then the sliding rod 63 is pushed to drive the insertion rod 64 to pass through the connecting ring 61 to block and lock the wing plate 5. When the wing plate 5 needs to be unfolded, after pulling the pull rod 67 to not block the L end of the sliding rod 63, the sliding rod 63 can be pulled and rotated downward to drive the insertion rod 64 to separate from the connecting ring 61, so as to drive the wing plate 5 to unfold by the activated oil cylinder 8 for loading and unloading goods.
