The lifting assembly 20 comprises a pair of slide bars 21 and a carrier 22 for carrying material. One end of the sliding rod 21 is fixedly connected with the bearing 22, the other end of the sliding rod 21, which is away from the bearing 22, is slidably assembled with the guide rod 11, and the sliding rod 21 can drive the bearing 22 to slide up and down along the guide rod 11.

The wheel assembly 30 is rotatably mounted at the bottom end of the frame 10, and can make the material cart 100 perform rolling motion under the driving of external force.

Referring to fig. 5, the process of transporting material by the material cart 100 is briefly described as follows, taking the example of transporting gas cylinders on a level ground with steps as follows:

first, the gas cylinder is placed on the carrier 22; then, the material trolley 100 loaded with the gas cylinder is pushed to the ground at a preset angle A; as shown in fig. 5(b) and 6, when a step is encountered, the bearing member 22 of the lifting assembly 20 is firstly overlapped with the edge of the step, i.e. the intersection line of the side surface and the top surface of the step, and then the material trolley 100 is slowly rotated, so that the guide rod 11 of the material trolley 100 gradually tends to be vertical to the horizontal ground, and the gas cylinder can be vertically placed on the step.

Therefore, the gas cylinder is pushed to the step through the material vehicle 100, and then the gas cylinder is placed on the top surface of the step through the lifting assembly 20 of the material vehicle 100, so that the gas cylinder can be easily carried to a high place without manual brute force in the whole process of carrying the gas cylinder by the material vehicle 100.

As shown in fig. 3, in one embodiment, the frame 10 further includes a plurality of connecting rods 12, the connecting rods 12 may be parallel to each other and connected between the two guide rods 11, and may be uniformly distributed on the frame 10 along the length direction of the guide rods 11, and the number of the connecting rods 12 may be set as appropriate according to the needs of the actual situation.

In other embodiments, the connecting rods 12 may be arranged on the frame 10 in a suitable manner according to the force applied to the frame 10, for example, several connecting rods 12 may be distributed in a crossing manner.

After the fixing portion 1411 of the end of the protection rod 141 passes through the positioning nut, another nut may be further assembled to the end of the fixing portion 1411 passing through the positioning nut to fix the protection rod 141 to the bracket 10, and for convenience of description, the nut assembled to the end of the fixing portion 1411 is referred to as a fixing nut.

The locking ring 142 is a part whose diameter size can be adjusted, and the locking ring 142 may be an existing plastic snap-lock band. As shown in fig. 3, the locking ring 142 may be sleeved on one of the fixing plates 13 for adjusting the tightness of the material when the material is fixed on the material cart, so as to cooperate with the protection rod 141 to perform a double-layer protection function when the material cart 100 transports the material.

Further, the material limiting part 14, the fixing plate 13 and the connecting rod 12 are connected with each other to form a containing frame matched with the shape of the material, and most of the surface of the material is in contact with the containing frame, so that the stability of the material vehicle 100 in the process of transporting the material is improved.
