A kind of sick bed back lifting device
Technical field
this utility model relates to a kind of sick bed back lifting device, belongs to technical field of medical equipment.
Background technology
The sick bed of Hospitals at Present, has back lifting device substantially, but sufferer often feel back lifting time comfortable not.Find through observing, this type of sick bed is when running back lifting action, the axially upset that in the middle part of bed body one of upper bed board is fixing, the problem now brought, because human body lies at above sick bed, therefore the abdominal part of sufferer can be allowed unavoidably to be squeezed, along with the carrying out of back lifting when ordinary hospital bed does back lifting motion, human body integral glides, and therefore patient often feels comfortable not.
Summary of the invention
The purpose of this utility model is, for operating beds back lifting mechanism Problems existing, this utility model discloses a kind of sick bed back lifting device.
The technical solution of the utility model is, a kind of sick bed back lifting device, comprises electric pushrod, support bar, connecting rod, upper bed board.
Below upper bed board, support bar is installed, support bar is by the fixed axis on it and be arranged on being hinged and connected on a body, quarter butt one end and the electric pushrod front end of support bar are hinged and connected, electric pushrod rear end and bed body are hinged and connected, the axial direction of described electric pushrod is vertical with bed body width, support bar can rotate around fixed axis, and the axial direction of fixed axis is consistent with the width of bed body, and encapsulate roller is equipped with on the stock top of support bar; Be hinged and connected with connecting rod one end in the middle part of the quarter butt of support bar, the hinge joint of the connecting rod other end is at upper bed board.
Described support bar is a bending staff design, and support bar is made up of long and short two sections of straight-bars, long and short two sections at an angle, length bar intersection is provided with fixed axis, and when fixed axis is arranged on hinge, support bar can rotate around fixed axis; The stock top of support bar is provided with encapsulate roller, and support bar can to support upper bed board and upwards overturn; The middle part of the quarter butt length direction of support bar is connected with connecting rod.
Operation principle of the present utility model as shown in Figure 3, this utility model promotes the quarter butt of support bar 3 by electric pushrod 2, the stock of support bar 3 is turned clockwise around the fixed axis on support bar 3, and the encapsulate roller 4 of the stock end of support bar 3 promotes upper bed board 7 and also turns clockwise; Owing to being connected with connecting rod 5 in the middle part of the quarter butt of support bar 3, when the quarter butt that electric pushrod 2 promotes support bar 3 forward time, promote connecting rod 5 simultaneously and also travel forward, just by connecting rod, upper bed board is drawn toward head of a bed direction.
The beneficial effects of the utility model are, during this utility model sick bed back lifting application of installation, when electric pushrod extends, electric pushrod promotes support bar and rotates around fixed axis, and support bar props up upper bed board; By connecting rod, upper bed board is drawn toward head of a bed direction again simultaneously, complete back lifting action.Such action can allow the abdominal part when back lifting of sufferer not be squeezed, and human body does not glide, and the back lifting posture of sufferer is compared and uses the back lifting posture of ordinary hospital bed more comfortable.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described:
A kind of sick bed back lifting of the present embodiment device as shown in Figures 1 to 6.
Bed body 1 medium position is provided with back lifting device, and back lifting device comprises electric pushrod 2, support bar 3, connecting rod 5, upper bed board 7.
Support bar 3 is a bending staff design, and support bar 3 is made up of long and short two sections of straight-bars, long and short two sections at an angle; Length bar intersection is provided with fixed axis, and when fixed axis is arranged on hinge, support bar 3 can rotate around fixed axis; Encapsulate roller 4 is equipped with on the stock top of support bar 3, and support bar 3 can to support upper bed board 7 and upwards overturn; The middle part of the quarter butt length direction of support bar is connected with connecting rod 5.
Support bar 3 is provided with below upper bed board 7, support bar 3 and bed body 1 are hinged and connected, support bar 3 is hinged and connected with electric pushrod 2 again, electric pushrod 2 rear end and bed body 1 are hinged and connected, the axial direction of described electric pushrod 2 is vertical with bed body 1 width, support bar 3 can rotate around fixed axis, the axial direction of fixed axis is consistent with the width of bed body 1, encapsulate roller 4 is equipped with on support bar 3 top, support bar 3 can to support upper bed board 7 and upwards overturn, simultaneously because upper bed board 7 is installed in a chute of body both sides 6, be hinged and connected by connecting rod 5 with support bar 3 again, when electric pushrod 2 extends, electric pushrod 2 promotes support bar 3 and rotates, support bar 3 props up upper bed board 7, by connecting rod 5, upper bed board 7 is drawn toward head of a bed direction again simultaneously, complete back lifting action.Such action can allow the abdominal part when back lifting of sufferer is not squeezed, human body does not glide, and the back lifting posture of sufferer is compared and uses the back lifting posture of ordinary hospital bed more comfortable.
Bed body in this utility model can carry out outer package, makes the effect as solid wood, and Soft Roll can be carried out in bed surface, makes patient feel comfortable.
This utility model also can assemble travel switch and control system, is designed to manually and automatically control, and is 36 or 48 volts by power supply transformation, safe and reliable, also can assemble reserve battery, in order to using when having a power failure.
