Description

Clamping device of shifting machine, working method and application

Technical Field

The invention relates to the field of barrier-free shifting instruments, in particular to a clamping device of a shifting machine.

Background

The shifting machine can help people who are inconvenient to move to shift positions from a wheelchair to sofas, beds, toilet bowls, seats and the like, and can also help solve series of living problems such as toileting, bathing and the like.

At present, the distance and the height of armpit support arms at the chest and the two sides of the existing shifting machine are fixed, and the distance is usually manually adjusted by using a special tool through adjusting the length of a telescopic rod. When using under the scene of a many people sharing equipment (like hospital or endowment mechanism), because the user fat thin of needs transport differs, the chest leans on the armpit support arm interval and the height of both sides must not be applicable to everyone, consequently every transport is alone, just need adjust once, and is very troublesome. And for this reason, if a plurality of devices are equipped at the same time, the cost is too high.

Therefore, designing a self-adaptive adjusting mechanism for the armpit support arm of the shifter becomes one of the technical problems to be solved in the art.
