At the same time, there is no need to repeatedly lift the patient off the bed surface, thereby avoiding secondary injuries and aggravating the condition.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A nursing bed support structure comprises a movable bed plate, a clamping plate, an upper gear plate, a fixed cover plate, a fixed bottom plate, a fixed bracket, a driving rod, and an anti-slip block. The lower part of the fixed bottom plate is connected to the fixed bracket, and the fixed bracket is connected to a plurality of self-locking universal wheels. The fixed bottom plate has placement grooves on both sides, and the placement grooves are adapted to the lower gear plate. The lower gear plate is connected to the placement grooves. The outer part of the lower gear plate fits the fixed bottom plate, and the lower part of the fixed bottom plate is connected to the support plate.

The middle gear plate is meshed with the upper gear plate, and the upper part of the middle gear plate is connected to the upper gear plate. The upper gear plate is adapted to the placement groove, and the upper gear plate is connected to the placement groove. The utility model describes that the upper part of the fixed base plate is connected to the fixed cover plate, the fixed base plate has supporting plates on both sides, the fixed cover plate has supporting plate grooves on both sides, the supporting plates are adapted to the supporting plate grooves, the supporting plates are connected to the supporting plate grooves, the upper gear plate has a positioning support rod, the lower part of the positioning support rod fits the supporting plate, the upper part of the positioning support rod fits the fixed cover plate, the fixed cover plate has an upper clamping block, the supporting plate has a lower clamping block, the positioning support rod has a limiting clamping groove, the upper clamping block and the lower clamping block are adapted to the limiting clamping groove, the upper clamping block is connected to the limiting clamping groove, and the limiting clamping groove is connected to the lower clamping block.

[0006] The utility model comprises a fixed cover plate having an upper portion fitted with a movable bed board, a mattress placed on the inner side of the movable bed board, a clamping plate fitted on the outer side of the movable bed board, the movable bed board having a plurality of handles, the clamping plate having a plurality of side through holes, the handles being adapted to the side through holes, the handles passing through the side through holes, the lower portion of the clamping plate fittingly fitting the fixed bottom plate, a positioning support sleeve being provided on the inner side of the clamping plate, the positioning support sleeve being connected to the positioning support rod through threads. Beneficial Effects

[0007] The lower gear plate, the middle gear plate and the upper gear plate are meshed and connected with each other and driven by a crank handle. The positioning support rods on both sides are respectively positioned and connected with the positioning support sleeves on both sides through positive and negative threads. As a result, when the positioning support rods on both sides are driven to rotate by turning the crank handle, the positioning support sleeves on both sides drive the clamping plates on both sides to simultaneously perform synchronous horizontal linear displacement inward or outward. When the clamping plates are displaced outward until the anti-slip block fits the inner end of the slide groove, the outward movement of the clamping plates is maximized. At this time, the horizontal distance between the clamping plates on both sides is greater than the horizontal distance between the handles on both sides. The movable bed board and the nursing bed body are in a state that can be quickly separated, and the handles can be conveniently used to lift the bed. Patients with limited mobility are carried to transfer vehicles or examination rooms and other narrow areas, avoiding the inconvenience caused by the large overall structure of the nursing bed, improving the efficiency of patient transfer, and allowing timely treatment. There is no need to repeatedly lift the patient off the bed, avoiding secondary injuries and worsening of the condition. When the clamping plate moves inward until its inner surface fits the outer surface of the movable bed board and the handle passes through the side perforations, the clamping plates on both sides clamp and fix the movable bed board, and the handles are embedded to double lock the movable bed board longitudinally and transversely, thereby improving the stability of the movable bed board and preventing the movable bed board from moving when the nursing bed is moved as a whole. The structure is reasonable.

[0008] The fixed bracket of the utility model supports the bottom of the fixed base plate and increases the overall mobility of the nursing bed by adding a self-locking universal wheel. The anti-slipping block increases the connection fulcrum between the fixed base plate and the positioning support sleeve and limits the position of the positioning support sleeve to keep it in a horizontal linear displacement to prevent it from separating and falling from the fixed base plate during the displacement adjustment process, thereby improving the structural stability. The anti-slipping block is longitudinally controlled by a shifting rod. When the shifting rod is shifted downward to drive the anti-slipping block to completely disengage from the slide groove, the fixed base plate's limiting fulcrum for the positioning support sleeve disappears. At this time, the clamping plate and the fixed base plate can be quickly disassembled, thereby improving the assembly efficiency of the nursing bed.

[0009] The utility model can quickly switch between the fixed and separated usage states of the movable bed board and the bed body according to the actual use needs of the patient. By separating the movable bed board, the patient with limited mobility can be conveniently carried to a transfer vehicle or an examination room or other narrow area, avoiding the inconvenience caused by the large overall structure of the nursing bed, improving the efficiency of patient transfer, so that timely treatment can be given, and there is no need to repeatedly lift the patient off the bed surface, avoiding secondary injuries and aggravating the condition.
