Technical Field

The utility model relates to the technical field of medical appliances, in particular to a castor locking device for an operating table.

Background

In the field of medical instruments, operating tables are important equipment tools for positioning patients in an operating room and providing a doctor with a good operating environment. In order to facilitate cleaning and transportation, operating tables are often provided with casters with locking and unlocking functions, and in general, when the operating tables need to be locked, each caster is directly and independently locked by friction force; or by conversion of various mechanical components, a plurality of support feet extend from the base. However, based on the clinical application scenes of the precise operation of an operating table and large bearing at a large angle, the common locking scheme has the limitation. For example, the castor landing scheme is only suitable for empty bed transportation and is not suitable for large bearing in the operation process, and because of the characteristics of the castor, the gravity center is easy to be unstable when an external accessory of an operating table or lateral force is applied, and the tipping unbalance is easy to be caused; the scheme that a plurality of supporting legs extend out of the base also can generate larger shaking quantity due to the fact that the whole bed is conducted due to the fact that the matching parts between shaft holes are precise or friction and abrasion are caused, the requirement of precise operation cannot be well met, and meanwhile, the gravity center of the base cannot be applied to the greatest extent due to the limitation of structural assembly.
