Description

Technical Field

[0001] The utility model relates to the field of nursing beds, in particular to a nursing bed with a motor-driven back-lifting and clamping linkage. Background Art

[0002] Nursing beds are generally powered beds, which are divided into electric or manual nursing beds. They are designed according to the patient's bedridden lifestyle and treatment needs, so that family members can accompany the patient, and they have multiple nursing functions and operation buttons, and are insulated and safe to use. They can be used by sick people, severely disabled people, the elderly, and healthy people during hospitalization or home treatment and rehabilitation, and they come in various sizes and forms. However, when the existing nursing beds are performing back-lifting operations, since there is no protection on the left and right, the patient is prone to sideways sliding after lifting the back, which poses certain safety hazards. Based on this, the utility model proposes a motor-driven back-lifting and clamping linkage nursing bed. Utility Model Content

[0003] The utility model aims to provide a nursing bed with a motor-driven back-lifting and clamping linkage function, so as to solve the above-mentioned problems.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses a motor-driven back-lifting and clamping linkage nursing bed, comprising a bed frame, a back-lifting motor is arranged on the inner wall of the head part of the bed frame, the working end of the back-lifting motor is fixedly hingedly connected to a connecting plate, and the other end of the connecting plate is fixedly connected to a rotating shaft; a back-lifting support rod and a clamping support rod are symmetrically arranged at the middle position of the rotating shaft, and the clamping support rods are symmetrically distributed on the outside of the back-lifting support rod; the other end of the back-lifting support rod is connected to a back-lifting frame, and the other end of the clamping support rod is connected to left and right clamping frames, and the left and right clamping frames are hingedly connected to one end of the back-lifting frame closely adjacent to it.

[0006] Furthermore, both ends of the rotating shaft are rotatably arranged on the bed frame.

[0007] Furthermore, the left and right clamping frames are symmetrically distributed on both sides of the back-lifting frame, and the back-lifting frame is located in the middle of the bed frame.

[0008] Furthermore, a roller is provided at the working end of the clamping support rod, and a roller groove matching with the roller is provided at the middle position of the back side of the left and right clamping frames.

[0009] Furthermore, slide grooves are symmetrically arranged on the back side of the back-lifting frame near the edge, and pulleys matching with the slide grooves are arranged at the end of the back-lifting supporting rod.

[0010] Compared with the prior art, the beneficial technical effects of the utility model are:

[0011] The motor of the utility model drives the nursing bed with back lifting and holding linkage to rotate through the back lifting motor to drive the connecting plate to rotate, thereby driving the rotating shaft to rotate, and driving the back lifting support rod and the holding support rod to rotate, so that the back lifting frame can rotate upward, and the left and right holding frames can hold the left and right sides at the same time to prevent the user from slipping sideways when lifting the back. In short, the motor of the utility model drives the nursing bed with back lifting and holding linkage to hold the left and right sides at the same time to prevent the user from slipping sideways when lifting the back, thereby improving the safety of use.

[0014] Explanation of the accompanying drawings: 1-1, bed frame; 1-2, back-lifting motor; 1-3, connecting plate; 1-4, rotating shaft; 1-5, back-lifting support rod; 1-6, holding support rod; 1-7, back-lifting frame; 1-8, left and right holding frames. DETAILED DESCRIPTION

[0015] like Figure 1 As shown, a motor-driven back-lifting and clamping linkage nursing bed comprises a bed frame 1-1, a back-lifting motor 1-2 is installed on the inner side wall of the head portion of the bed frame 1-1, the working end of the back-lifting motor 1-2 is fixedly hingedly connected to a connecting plate 1-3, and the other end of the connecting plate 1-3 is fixedly connected to a rotating shaft 1-4. A back-lifting support rod 1-5 and a clamping support rod 1-6 are symmetrically installed in the middle position of the rotating shaft 1-4, and the clamping support rod 1-6 is symmetrically distributed on the outside of the back-lifting support rod 1-5; the other end of the back-lifting support rod 1-5 is connected to a back-lifting frame 1-7, and the other end of the clamping support rod 1-6 is connected to left and right clamping frames 1-8, and the left and right clamping frames 1-8 are hingedly connected to one end of the back-lifting frame 1-7.

[0016] Both ends of the rotating shaft 1-4 are rotatably mounted on the bed frame 1-1.

[0017] The left and right holding frames 1-8 are symmetrically distributed on both sides of the back-lifting frame 1-7, and the back-lifting frame 1-7 is located in the middle position of the bed frame 1-1.

[0018] A roller is installed at the working end of the clamping support rod 1-6, and a roller groove matching the roller is installed at the middle position of the back side of the left and right clamping frames 1-8.

[0019] A slide groove is symmetrically installed on the back side of the lifting frame 1-7 near the edge, and a pulley matching the slide groove is installed at the end of the lifting support rod 1-5.
