Problems solved by technology
[0002] At present, for consignment vehicles, such as pallet trucks, the rotation method is to use multiple steel bars to rotate the hubs fixedly installed. However, due to the difference in size of the multiple steel bars, the outward extrusion resistance of the hubs will change. Inconsistent, resulting in different forces on the steel bars, so the overall service life is low

The invention discloses an adjustable hub for a trailer. The adjustable hub comprises a plate-shaped shell and an annular hub frame, wherein a tire is mounted on the side surface of the annular hub frame. A plurality of steel bars and the annular hub frame are movably connected, and the property that the two ends of each steel bar can play a supporting role when the steel bars contract inwards isutilized, so that the symmetrical upward supporting effect on the hub frame is achieved, and the impact resistance of the hub frame is improved; meanwhile, when the multiple steel bars contract, contraction driving is conducted through internal air negative pressure, so that the steel bars are the same in force when contracting; and due to the fact that the contraction force of the steel bars is the same, the upward supporting force formed by changing the spatial positions of the steel bars is the same, the steel bars with different sizes are changed into the property that the steel bars are different in supporting angles, the supporting force is not affected, the supporting force of the steel bars is consistent, therefore, the impact resistance of each part of the annular hub is consistent, and the protection effect on parts is improved.
Description
technical field [0001] The invention relates to the technical field of wheel bases, in particular to an adjustable wheel base for pallet trucks. Background technique [0002] At present, for consignment vehicles, such as pallet trucks, the rotation method is to use multiple steel bars to rotate the hubs fixedly installed. However, due to the difference in size of the multiple steel bars, the outward extrusion resistance of the hubs will change. Inconsistency results in different forces on the steel bars, resulting in a low overall service life. Contents of the invention [0003] The object of the present invention is to provide an adjustable hub for pallet trucks, so as to solve the problems raised in the background technology above. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an adjustable wheel stand for pallet trucks, comprising a plate-shaped shell and an annular wheel stand with tires installed on t...
