When the guardrail is lowered, the nursing space can be expanded, making it convenient for nursing staff to provide barrier-free care on both sides of the patient.

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

[0005] A lifting guardrail for a nursing bed comprises a bed board, a lifting board, a limiting plate, a protective rod, a control rod, a positioning support rod, and a positioning locking sleeve. The upper part of the bed board is connected to a fixed guardrail, the lower part of the bed board is connected to a fixed bracket, the inner side of the fixed bracket is connected to a reinforcing support rod, and the lower part of the fixed bracket is connected to a self-locking universal wheel.

[0006] The limit plate described in the utility model comprises a lower support plate, and the installation support sleeve comprises an upper support plate, the upper support plate is connected to the upper part of the positioning support rod, and the lower part of the positioning support rod is connected to the lower support plate, the lower support plate has a lower clamping plate, the upper support plate has an upper clamping plate, the positioning support rod has a limit clamping slot, the lower clamping plate and the upper clamping plate are adapted to the limit clamping slot, the upper clamping plate is connected to the limit clamping slot, and the limit clamping slot is connected to the lower clamping plate.

[0007] The utility model discloses a positioning support rod with a driven gear plate at the inner end, a positioning support rod with a threaded connection at the outer end, a positioning locking sleeve with a locking sleeve through-hole, a positioning support sleeve with a positioning locking groove, the positioning locking groove and the locking sleeve through-hole are adapted to the positioning locking sleeve, the positioning locking sleeve passes through the locking sleeve through-hole, and the positioning locking sleeve is connected to the positioning locking groove.

[0008] The utility model describes a driven gear plate meshing with a driving gear plate, the driving gear plate is connected to the driven gear plate, the driving gear plate has a central support rod at the bottom, the limit plate has a central support sleeve, the central support rod is connected to the central support sleeve, the driving gear plate has a limit block at the top, the limit block fits the protective rod, the limit block has a control rod, the control rod passes through the protective rod and the lifting plate in sequence, the control rod is connected to the knob, and the knob fits the lifting plate.

[0009] The utility model discloses a protective rod externally fitted with a positioning sleeve, the protective rod having a slide groove, the slide groove is adapted to a roller, the roller is connected to the slide groove, the roller slides in the slide groove, the roller is connected to the positioning sleeve via an axle rod, and the axle rod is sequentially connected to the positioning sleeve and the roller. Beneficial Effects

[0010] The reinforcing support rod of the utility model reinforces the supporting structure of the fixed bracket to improve its supporting strength and increase the stability of the bed board support. At the same time, a storage space is formed between the bottom of the bed board, which can be used to place items such as patient clothing or medical supplies, thereby expanding the storage space of the nursing bed. The self-locking universal wheels increase the overall mobility of the nursing bed, which is convenient for rapid transfer of patients with limited mobility in emergency situations.

[0011] When the patient is lying on the bed, the lifting plate can be lifted up to drive the protective rod to move up, and the driving gear plate and the driven gear plate can be linked by turning the knob to control the positioning lock sleeve. When the positioning lock sleeve is displaced to the position where it is embedded in the positioning lock groove, the positioning support sleeve locks and supports the protective height of the protective rod, and the protective rod protects the two sides of the bed plate to prevent the patient from falling off the bed plate when turning over, thereby increasing the protection for the patient. When the knob is turned in the opposite direction to drive the positioning lock sleeve to be displaced to the position where it is completely separated from the positioning lock groove, the positioning support sleeve for the protective rod disappears. At this time, the protective rod will automatically fall to the lifting plate and be stored in the storage groove, thereby maintaining the flatness of the bed plate, facilitating the patient to get on and off the bed, and expanding the nursing space, so that the nursing staff can perform barrier-free nursing on both sides of the patient. When the protective rod falls and moves, the roller slides synchronously in the slide groove accordingly, so as to reduce the friction resistance generated when the protective rod moves downward, and avoid jamming when the protective rod falls.

[0012] The movable guardrails on both sides of the utility model can be independently controlled and adjusted according to actual nursing needs, and an upper rubber pad and a lower rubber pad are respectively provided on the lower side of the lifting plate and the upper side of the bed board. The rubber pads are made of rubber and have a certain elasticity. They can buffer the impact force generated between the lifting plate and the bed board when falling, reduce the vibration and noise caused by the impact, and have a reasonable structure.

[0013] The limit plate of the utility model limits the lifting range of the lifting plate to prevent the protection rod from being separated from the bed board. At the same time, the lower support plate and the upper support plate inside the utility model cooperate with each other to provide limit support for the positioning support rod, so that the axial rotation can be performed while the lateral position and the longitudinal height remain unchanged, thereby preventing the movement and deviation from affecting the linkage effect between the components and improving the structural stability.

[0014] The utility model increases the protection for patients by adding movable guardrails on both sides of the bed board, and the movable guardrails can be raised and lowered by turning a knob, which is convenient for patients to get on and off the bed. When the guardrails are lowered, the nursing space can be expanded, which is convenient for nursing staff to provide barrier-free nursing on both sides of the patient.
