Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Please see Figure 1 This utility model provides a technical solution: a pallet transport vehicle with protective railings, including a pallet transport vehicle body 1. A fixing cylinder 2 is provided above the top front end of the pallet transport vehicle body 1. Fixing seats 12 are fixedly connected to the bottom two sides of the fixing cylinder 2. The bottom of the fixing seats 12 is fixedly connected to the top of the pallet transport vehicle body 1. A fixing rod 3 is fixedly connected to the bottom rear end of the pallet transport vehicle body 1. The fixing rod 3 is provided through on both sides. A partition plate is fixedly connected to the center of the inside of the fixing rod 3. The centers of both sides of the partition plate are fixedly connected to the fixed ends of a telescopic rod 6. The telescopic end of the telescopic rod 6 and the opening surface of the fixing rod 3 are on the same vertical plane. A first connecting plate 5 is fixedly connected to the fixed end of the telescopic rod 6. A guard plate is fixedly connected to the top of the first connecting plate 5. 4. The front end of the guard plate 4 is located at the front end of the pallet truck body 1. The front end of the guard plate 4 is fixedly connected to the second connecting plate 9. The center of the back of the second connecting plate 9 is fixedly connected to the sliding rod 10. By setting guard plates 4 on both sides of the existing pallet truck, the guard plates 4 protect the pallet placed above the pallet truck body 1 and prevent the pallet from falling. In addition, during use, the distance between the guard plates 4 can be adjusted according to the width of the pallet. Specifically, when in use, the pallet is first placed above the pallet truck body 1. When the pallet is wide, the two sides of the pallet will cause the guard plates 4 to extend outward, thereby causing the telescopic rod 6 and the bidirectional telescopic rod 13 to move outward, thus making it very easy to change the distance between the guard plates 4 on both sides.

[0019] Please see Figure 2 and Figure 3This utility model provides a new embodiment in which a fixed cylinder cavity 11 is provided through one side of the fixed cylinder 2. A bidirectional telescopic rod 13 is fixedly connected to the center of the fixed cylinder cavity 11. Telescopic parts 14 are slidably connected to both ends of the bidirectional telescopic rod 13. A sliding rod 10 is fixedly connected to the other end of the telescopic part 14. A buffer spring 15 is sleeved on the surface of the telescopic part 14. The two ends of the buffer spring 15 are fixedly connected to the bottom of the sliding rod 10 and the telescopic part 14, respectively. When the pallet truck body 1 turns, a certain centrifugal force will be generated on a certain guard plate 4, causing the guard plate 4 at this point to move outward. Due to the elasticity of the buffer spring 15, the centrifugal force will be appropriately buffered, making the guard plate more stable when placed above the pallet truck. In addition, after the guard plate is taken out, the buffer spring 15 on the surface of the bidirectional telescopic rod 13 will also rebound, causing the guard plates 4 on both sides to rebound back to their original positions, which is convenient for use.

[0020] Please see Figure 1 and Figure 2 This utility model provides a new embodiment in which a wave plate 8 is fixedly connected from the top of the guard plate 4 to the rear end of the guard plate 4. A bending part 7 is provided at the other end of the wave plate 8 to improve the strength of the wave plate 8. The cross-section of the wave plate 8 is wave-shaped, and the arc height of the wave shape increases from the outside to the inside. Considering the different heights of the guard plate, the arc position of the wave plate 8 is increased sequentially. When the height of the guard plate is low, the two sides of the guard plate will be located on the bottom arc side. When the height of the guard plate is high, the two sides of the guard plate will be located on the higher arc side, and so on. The wave plate 8 is an elastic plate that can be bent appropriately. After the guard plate is placed, it can be turned appropriately, thereby changing the length of the wave plate 8. It can be used to place guard plates of different widths and can stably place guard plates of different widths, which is convenient for use.

[0021] Working principle: When in use, the pallet is placed on the main body 1 of the pallet transport vehicle. When the pallet is wide, the two sides of the pallet will extend the protective plates 4 outward, thereby moving the telescopic rod 6 and the bidirectional telescopic rod 13 outward. This makes it very easy to change the distance between the two protective plates 4. After the pallet is moved to a suitable place by the main body 1 of the pallet transport vehicle, the pallet is taken out. The buffer spring 15 on the surface of the bidirectional telescopic rod 13 will also rebound, causing the two protective plates 4 to return to their original positions for convenient subsequent use.

[0022] Additionally, when the pallet truck body 1 turns, a certain centrifugal force will be generated on a certain guard plate 4, causing the guard plate 4 to move outward. Due to the elasticity of the buffer spring 15, the centrifugal force will be appropriately buffered, making the guard plate more stable when placed above the pallet truck.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
