[0002] A mobile platform is a widely used climbing aid. The mobile platform is provided with multiple universal wheels at the bottom to realize movement. Each universal wheel can be locked and opened to realize locking and opening of the mobile platform. In some factory workshop application environments, when climbing work needs to be performed with the aid of the mobile platform, if the work space is small, the mobile platform needs to be pushed into a relatively narrow space, and then locking of the mobile platform needs to be realized. The worker needs to go around the mobile platform to realize locking of each universal wheel. However, the narrow space makes it impossible for the worker to reach the position of each universal wheel, and only the locking of the two universal wheels at the position where the worker is located when pushing the mobile platform can be realized. Therefore, the locking stability of the mobile platform is poor, and there is a safety hazard. CONTENT OF THE UTILITY MODEL

The conventional mobile platform is usually provided with multiple universal wheels at the bottom, each universal wheel can be locked or opened, and each universal wheel is locked to lock the mobile platform, and each universal wheel is opened to freely move the mobile platform. However, the mobile platform with such structure has certain defects in actual application. For example, when used in a relatively narrow space, the mobile platform is pushed into the narrow space, and due to the limited space, the relevant operating personnel cannot walk around the mobile platform, so the universal wheels cannot be conveniently locked, and only the two universal wheels at the position where the operating personnel pushes the mobile platform can be locked. That is, if the mobile platform has a head and a position, two universal wheels are arranged at the corresponding head position and the corresponding tail position of the bottom of the mobile platform, a total of four universal wheels are arranged, and when the operating personnel holds the head to push the mobile platform into the narrow space, the operating personnel cannot reach the tail of the mobile platform, and only the two universal wheels at the head of the mobile platform can be locked, and the remaining two universal wheels cannot be locked, which has a safety hazard. The mobile platform of the present application aims to facilitate the safety locking of the mobile platform.
