Abstract

The utility model discloses a hydraulic health-care bed which is composed of a hydraulic part and an electric appliance part. The utility model is specifically composed of a front and a back bed frame, a hydraulic cylinder, a hydraulic oil tank, a timing circuit, and a control switch. The front bed frame and the back bed frame are splits. When use, the front bed frame and the back bed frame are installed into a whole. The timing circuit can be used to make the bed frame lift in the set time. The structure of the hydraulic health-care bed is simple, and the operation is convenient.

Description

Hydraulic health-care bed

The invention belongs to the electrical machinery field, is a kind of by hydraulically powered multifunction hydraulic health care bed specifically.

At present, the kind of health care bed is more, and its structure also is that many formulas are various; Also have liftablely, but structure is all complicated, and function is incomplete yet.

The purpose of this utility model is that design is a kind of simple in structure, easy to use, not only arbitrarily lifting of backrest, and also lifting and have health care, multiple functions such as timing arbitrarily of shank.

This utility model is made up of front bedstead 22, back bedstead 23, hydraulic control part and electrical control part, and front bedstead 22 is provided with backrest lifter plate 1, establishes shank lifter plate 2 on the back bedstead 23; Lifter plate 1 links to each other with 5 push rod with hydraulic cylinder 4 respectively with 2, lifting for control hydraulic cylinder 4 and 5, also be provided with motor D, gear pump 8, oil filter 7, with 7 be connected with two 3-position 4-way solenoid directional control valves 10,11, the other end 10,11 is connected to timing throttle valve 16,17 respectively, check valve 13,14, last joining with interface A1, A2, B1, B2 of

joint

18,19,20,21 also is provided with hydraulic fluid tank 3, overflow valve 9 and electric appliance control box 6 for the realization hydraulic control.

This utility model compared with prior art, convenient and flexible operation is used steadily, back and shank are risen and puts down.

Sketch map when Fig. 1 sets level for this utility model lifter plate.

Sketch map when Fig. 2 is each lifter plate rise of this utility model.

Fig. 3 is a hydraulic control part sketch map of the present utility model.

Enforcement of the present utility model can be as Fig. 1, Fig. 2, shown in Figure 3, and bedstead is made by the timber metal material, and its appliance controling plate is installed in head of a bed position.

Claims

A kind of multifunction hydraulic health care bed of forming by mechanical-hydraulic part and electrical appliance part, it is characterized in that described health care bed is by front bedstead 22, back bedstead 23, hydraulic control part and electrical control part are formed, front bedstead 22 is provided with backrest lifter plate 1, back bedstead 23 is provided with shank lifter plate 2, lifter plate 1 links to each other with 5 push rod with hydraulic cylinder 4 respectively with 2, for the lifting of controlling hydraulic cylinder 4 and 5 also is provided with motor D, gear pump 8, oil filter 7, with 7 be connected with two 3-position 4-way solenoid directional control valves 10,11,10,11 the other end is connected to timing throttle valve 16 respectively, 17, check valve 13,14, joint 18,19,20,21, last and interface A1, A2, B1, B2 joins, for realizing hydraulic control, also be provided with hydraulic fluid tank 3, overflow valve 9 and electric appliance control box 6.
