Abstract

The utility model relates to a lifting mechanism of hospital bed. The lower ends of a first down connecting bar (1) and a second down connecting bar (10) are connected with the mutual pivots of the first down knighthead (11) and the second down knighthead (12) respectively, the upper ends of the first down connecting bar (1) and the second down connecting bar (10) are connected with a upper end mutual pivot of the first up connecting bar (2) and the second up connecting bar (8), the pivots on the other upper ends of the first up connecting bar (2) is connected with an end of a top connecting bar (6), the other and of the second upper connecting bar (8) is connected with the other end of the other end of the top connecting bar (6). The up pivot of the top connecting bar (6) is connected with an end of a piston (5); a cylinder body (7) matching with the piston (5) is connected with the pivot of a bed (4). The piston can slide in the cylinder body by operating the cylinder, so as to control the lifting or falling of the bed. The utility model has the advantages of safe and reliable utilizing.

Description

The bed body elevating mechanism of sick bed

Technical field

This utility model relates to a kind of bed body elevating mechanism of sick bed.

Background technology

In the prior art, the lifting of sick bed mainly is to rely on screw rod to drive elevating mechanism that many rod members connect to make sick bed be risen or descend, its screw portion need be by the handle operation that exposes outside, operation inconvenience, and after arriving specified altitude assignment sick bed stable bad.

Summary of the invention

The purpose of this utility model is to provide a kind of bed body elevating mechanism of sick bed easy and simple to handle.

The technical solution of the utility model is: a kind of bed body elevating mechanism of sick bed, the bottom of first lower link and second lower link is connected with the phase pivot of first lower support bar with second lower support bar respectively, the upper end of first lower link and second lower link respectively with first on the connecting rod and second an end phase pivot of connecting rod be connected, the pivotally connected end that the top connecting rod is arranged, the other end of connecting rod on first, pivotally connected the other end that the top connecting rod is arranged, the other end of connecting rod on second, the coaxial pivotally connected body that has in pivotally connected place on described first lower link and first between the connecting rod, the coaxial pivotally connected body that has in pivotally connected place on described second lower link and second between the connecting rod, described top connecting rod head lamp brush guard pivot is connected with an end of piston, and the cylinder body that matches with described piston is pivotally connected with the bed body.

This utility model compared with prior art has following advantage:

Make piston slide in cylinder body by the operation cylinder, can control the rising or the decline of a body, after the height of bed body put in place, the position of piston and cylinder body was relatively stable, and the height of bed body is also stable, so this utility model is safe in utilization.
