DETAILED DESCRIPTION

[0017] Reference Figures 1 to 3 The utility model is further described in detail.

[0018] A flexible transport vehicle comprises a base plate 1, rollers 2, push rods 3, fixing mechanisms 4 and fixing plates 8. The rollers 2 are provided with four rollers arranged in a rectangular shape at the bottom of the base plate 1. The push rods 3 are fixed to one end of the base plate 1. The fixing mechanisms 4 are fixed to the base plate 1. The fixing plates 8 are provided with two fixing mechanisms 4, which are respectively matched with the fixing mechanisms 4.

[0019] The fixing mechanism 4 includes a first limiting plate 41, a second limiting plate 42, a moving block 43, a motor 44 and a screw rod. The first limiting plate 41 is fixed to one end of the bottom plate 1 and is close to the push rod 3. The second limiting plate 42 is placed on the other end of the bottom plate 1. A slide groove 5 is provided on the bottom plate 1. The motor 44 is fixed to one side of the bottom plate 1. The motor 44 includes a rotating shaft 6. The rotating shaft 6 passes through the bottom plate 1 and extends into the slide groove 5 and is fixedly connected to the screw rod. The moving block 43 is placed in the slide groove 5 and is fixedly connected to the second limiting plate 42. A threaded hole 7 is provided on the moving block 43. The screw rod passes through the threaded hole 7 and is threadedly connected to the threaded hole 7.

[0020] By placing the material on the base plate 1, the motor 44 is started to rotate the shaft 6, and the shaft 6 rotates the screw, and the screw is threadedly connected to the threaded hole 7, so that the screw rotates and drives the moving block 43 to move, and the moving block 43 drives the second limit plate 42 to move, and the second limit plate 42 moves toward the first limit plate 41 until the second limit plate 42 hits the material, thereby fixing the material on the base plate 1, thereby preventing the material from falling during the transportation process.

[0021] The fixed plate 8 is composed of a first plate body 81, a second plate body 82 and a third plate body 83 which are movably connected. Two corresponding limiting grooves 9 and a storage groove 14 are opened on the bottom plate 1. The first plate body 81, the second plate body 82 and the third plate body 83 extend into the limiting groove 9 in sequence. The two ends of the first plate body 81 are movably connected to one end of the first limiting plate 41 and the second plate body 82 respectively. The two ends of the third plate body 83 are movably connected to the other end of the second limiting plate 42 and the second plate body 82 respectively. One side of the first plate body 81 and the third plate body 83 is respectively provided with a first fixing groove 15 and a second fixing groove 16. Both ends of the second plate body 82 are provided with sliders 10, which are respectively placed in the first fixing groove 15 and the second fixing groove 16 for sliding.

[0022] The first limiting plate 41 is embedded with a first magnet 11, the first plate body 81 is embedded with a second magnet 12 that is attracted to the first magnet 11, the second limiting plate 42 is provided with a groove 13, and the third plate body 83 extends into the groove 13;

[0023] By taking out the second plate 82 from between the first plate 81 and the third plate 83, and then sliding the third plate 83 toward the first plate 81, the second limiting plate 42 is moved until the second limiting plate 42 contacts the third plate 83, and the movement of the second limiting plate 42 is stopped, and then by taking out 1 to 2 of the first plate 81, the second plate 82 or the third plate 83 from the limiting groove 9, and then adjusting according to the length of the material stacking, the stability of the material on the bottom plate 1 is improved, and at the same time, by respectively providing the first plate 81, the second plate 82 and the third plate 83 at both ends of the bottom plate 1, the material will fall from both ends of the bottom plate 1 during transportation, and the first plate 81 is fixed to the second limiting plate 42 by the first magnet 11 and the second magnet 12, so as to further improve the stability of the first plate 81 on the bottom plate 1.

[0024] At the same time, the storage groove 14 plays the role of accommodating the first plate body 81, the second plate body 82 and the second plate body 82.

[0025] Working principle: First, the material is piled up on the bottom plate 1, and then the motor 44 is started to rotate the shaft 6 on the motor 44, thereby driving the screw to rotate, and the moving block 43 is moved under the rotation of the screw, and then the moving block 43 drives the second limit plate 42 to move until the third plate body 83 extends into the groove 13 and contacts the groove 13, thereby enclosing the material to prevent the material from falling from the bottom plate 1 when moving. When the piled material is less, the second plate body 82 can be moved upward, thereby driving the slider 10 in the first fixed groove 15 on the first plate body 81 and the second fixed groove 16 on the third plate body 83. Slide inside until the slider 10 slides out of the first fixing groove 15 and the second fixing groove 16, and at the same time, the second plate body 82 moves out from between the first plate body 81 and the third plate body 83, and then slide the third body in the limiting groove 9 until it contacts the first plate body 81, and then start the motor 44 to drive the second limiting plate 42 to move toward the third plate body 83, until the second limiting plate 42 contacts the third plate body 83 and the material, so that the material is more stable during transportation, and then place the disassembled second plate body 82 in the storage groove 14 for storage, and finally push the bottom plate 1 and the roller 2 to move by grasping the push rod 3.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
