Description

Movable limiting assembly and cleaning equipment

Technical Field

The utility model relates to the technical field of cleaning devices, in particular to a movable limiting assembly and cleaning equipment using the same.

Background

The floor cleaning machine is a professional cleaning device and is widely applied to places such as commercial buildings, industrial places, medical institutions, schools, hotels and the like for cleaning floors. The portable bicycle has various designs, and has different types such as hand-held type, push type or riding type, so as to adapt to the requirements of different places.

The hand-held floor washer is used for cleaning the floor by pushing the floor washer through the hand-held handle, and the handle of the floor washer is usually designed to be longer in order to facilitate the user to support the handle to walk in the operation process. However, long handles also cause inconvenience in storage. For this reason, there has been a floor scrubber in which a handle is detachable, and a user can detach the handle when not in use to reduce the occupied space.

The handle on the market is generally connected with the groove buckle in the floor washer through a lug, and when the floor washer is installed, the handle is only required to be inserted into the floor washer and the lug is connected with the groove buckle. When the handle is detached, the lug is required to be pressed to move towards the handle direction, and the handle can be removed after the lug is separated from the groove. Since the bump is integrally formed with the handle, i.e., the bump is made of the same material as the handle, pressing the bump requires the application of a suitable force, depending on the bending capability of the handle. When the handle has higher bending capability, namely the handle is softer, the lug is easier to press, so that the lug is separated from the groove. However, since the handle has a high bending capability, the bump is not firmly clamped with the groove, and the user needs to hold the handle all the time to walk in the use process of the floor washing machine, which may cause the bump to be separated from the groove, and even cause the handle to be directly pulled out from the inside of the floor washing machine. When the bending capability of the handle is weak, namely the handle is hard, the lug is difficult to move and press towards the handle direction, and a great amount of force is required to be applied by a user to enable the lug to be separated from the groove, so that the user experience is affected.

Therefore, there is a need for a movable stop assembly that allows a handle to be movably coupled to a floor scrubber in a more optimal manner.
