[0005] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0006] A family care bed back-lifting mechanism comprises a bed frame and a folding bed board movably arranged on the top of the bed frame;

[0007] Buckles are symmetrically arranged on both sides of the bottom of the folding bed board, and an anti-skid pad is arranged on the top wall of the buckle, and a plurality of groups of spaced slots are opened at the bottom of the anti-skid pad, a fixed valve is rotatably arranged on the inner side of the bottom of the buckle, and a limit plate is rotatably arranged on the top of the fixed valve, and a locking plate matching the slot is arranged on the top of the limit plate, and a winding box is arranged on one side of the bottom of the folding bed board, and a winding roller is rotatably arranged inside the winding box, and winding springs are arranged at both ends of the winding roller, a restraining belt is wrapped around the outer side of the winding roller, and a baffle is arranged at one end of the restraining belt.

[0008] As a further solution of the utility model: guardrails are symmetrically arranged on both sides of the bed frame, and the guardrails are located on both sides of the folding bed board.

[0009] As a further solution of the utility model: a back-lifting frame is arranged at the bottom of the bed frame, and the back-lifting frame is a crank frame with two ends being coaxially rotatable, and the other end of the back-lifting frame is fixedly connected to the bottom of the folding bed board.

[0010] As a further solution of the utility model: an electric shaft is arranged at the bottom of the bed frame, and one end of the electric shaft is connected to the back lifting frame.

[0011] As a further solution of the utility model: a hanging frame is arranged at the bottom of the bed frame, a supporting seat is arranged at the bottom of the hanging frame, a moving seat is arranged at the bottom of the supporting seat, and universal wheels are symmetrically arranged at the bottom of the moving seat.

[0012] As a further solution of the utility model: a control box is arranged on one side of the bed frame near the edge.

[0013] Beneficial effects of the utility model:

[0014] The utility model discloses that when lifting the patient's back, the mattress can be stably fixed by the restraint belt, thus preventing the mattress from shifting, reducing the frequency of medical staff tidying up the mattress, and alleviating the workload of medical staff. The arranged winding roller can wind up the restraint belt to prevent it from scattering outside, thus making it convenient for medical staff to store it. The protrusion arranged on the engaging plate cooperates with the clamping groove provided on the anti-slip pad, thereby effectively fixing the two ends of the restraint belt, preventing the restraint belt from causing excessive rotation of the winding roller during the pulling process, resulting in excessive deformation of the torsion spring, thus ensuring the normal use of the winding roller.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, a family care bed back-lifting mechanism comprises a bed frame 1 and a folding bed board 2 movably arranged on the top of the bed frame 1, wherein the bed frame 1 forms a stable support for the folding bed board 2, and a mattress can be placed on the folding bed board 2;

[0024] The bottom of the folding bed board 2 is symmetrically provided with snap fasteners 10 on both sides, the top wall of the snap fasteners 10 is provided with anti-skid pads 11, and the bottom of the anti-skid pads 11 is provided with a plurality of groups of spaced slots 12, a fixed valve 13 is rotatably provided on the inner side of the bottom of the snap fastener 10, a limit plate 14 is rotatably provided on the top of the fixed valve 13, and a locking plate 15 matching the slot 12 is provided on the top of the limit plate 14, a winding box 16 is provided on one side of the bottom of the folding bed board 2, a winding roller 17 is rotatably provided inside the winding box 16, and winding springs are provided at both ends of the winding roller 17, a restraining belt 18 is wound around the outside of the winding roller 17, and a baffle 19 is provided at one end of the restraining belt 18. When the device is in use, the baffle 19 is pulled so that the restraining belt 18 is tightened. The belt 18 passes through the inside of a group of fasteners 10 to bind the mattress, and finally passes through the inside of another group of fasteners 10. The fixing valve 13 can drive the clamping plate 15 to move. The protrusions provided on the clamping plate 15 cooperate with the clamping grooves 12 provided on the anti-slip pad 11, thereby effectively fixing the two ends of the restraint belt 18. While ensuring that the restraint belt 18 can stably fix the mattress, it also avoids the restraint belt 18 causing excessive rotation of the winding roller 17 during the pulling process, resulting in excessive deformation of the torsion spring, thereby ensuring the normal use of the winding roller 17. When the device is not in use, the restraint belt 18 can be rolled up by the winding roller 17 to prevent it from being scattered outside, making it convenient for medical staff to collect it.

[0025] In this embodiment, specifically, guardrails 3 are symmetrically arranged on both sides of the bed frame 1, and the guardrails 3 are located on both sides of the folding bed board 2. The guardrails 3 provide good protection for the patient to prevent the patient from falling off the nursing bed during the turning process, and the guardrails 3 can be raised and lowered, which is convenient for medical staff to provide daily care for the patient.

[0026] In the present embodiment, specifically, a back-lifting frame 4 is provided at the bottom of the bed frame 1, and the back-lifting frame 4 is a crank frame with two ends coaxially rotatable, and the other end of the back-lifting frame 4 is fixedly connected to the bottom of the folding bed board 2. Specifically, an electric shaft 5 is provided at the bottom of the bed frame 1, and one end of the electric shaft 5 is connected to the back-lifting frame 4. When it is necessary to lift the patient's back, the electric shaft 5 is started, and the electric shaft 5 contracts to drive the back-lifting frame 4 to bend. When the back-lifting frame 4 is bent, the end thereof connected to the bottom of the folding bed board 2 can lift the folding bed board 2 upward, thereby achieving the purpose of assisting medical staff to lift the patient's back.

[0027] In the present embodiment, specifically, a hanging frame 6 is provided at the bottom of the bed frame 1, a supporting seat 7 is provided at the bottom of the hanging frame 6, a moving seat 8 is provided at the bottom of the supporting seat 7, and universal wheels are symmetrically provided at the bottom of the moving seat 8. A control box 9 is provided on one side of the bed frame 1 near the edge. The hanging frame 6 and the supporting seat 7 support the bed frame 1, thereby ensuring the stability of the device when in use. The universal wheels provided on the moving seat 8 facilitate the movement and transportation of the entire device.

[0028] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
