Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically to a vehicle equipped with rollers. Background Technology

[0002] Various types of vehicles (such as large equipment bases, material handling boxes, and heavy containers) are widely used in industrial production, logistics, and daily life. These vehicles are usually large and heavy, making them very inconvenient to move. To improve their mobility, a common practice is to install wheels on them.

[0003] Currently, there are two main ways to add wheels to vehicles: one is fixed welding or bolt fastening, and the other is using detachable caster wheel assemblies. While fixed installation provides a secure connection, it suffers from irreversibility and poor flexibility; once installed, it is difficult to remove or adjust, and it can cause permanent damage to the vehicle itself. Existing detachable caster assemblies often use simple pins or bolts to connect to pre-drilled interfaces on the side of the vehicle. This connection method has the following significant drawbacks: First, the connection strength and stability are often insufficient, easily loosening or even detaching when carrying heavy loads or traversing bumpy roads, posing a safety hazard; second, most simple casters lack braking functionality, making it impossible for the vehicle to reliably stop on slopes or uneven ground, easily leading to slippage; third, their installation position is usually fixed, unable to be flexibly adjusted according to changes in the vehicle's center of gravity or actual usage scenarios, resulting in poor versatility.
