Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-5 Shown, this implementation mode provides a nursing bed with a guardrail lift - type anti - fall function, including a nursing bed 1, and the nursing bed 1 includes: a bed frame 2, a bed board 3. A guardrail 4 is arranged above the bed frame 2. The guardrail 4 includes: an armrest 401, a rotating frame 403. Protective tubes 402 are connected in an array between the armrest 401 and the rotating frame 403. Rotating ear plates 404 are arranged in an array on the lower surface of the rotating frame 403. A rotating groove 201 is opened inside the bed frame 2 below the rotating ear plates 404. The rotating frame 403 is movably connected to the rotating groove 201 through the rotating ear plates 404. Positioning holes 202 are opened on the side surface of the bed frame 2. A limiting mechanism 405 is installed on the upper surface of the rotating frame 403. A limiting pin 409 is installed inside the limiting mechanism 405. The limiting pin 409 is fixedly connected to an anti - detachment backing plate 411 through a positioning spring 410. The limiting pin 409 is clamped with the positioning hole 202. An anti - detachment backing plate 411 is installed on the outer side of the lower end of the limiting pin 409. A positioning spring 410 is arranged on the outer side of the limiting pin 409 above the anti - detachment backing plate 411. A limiting through - hole is opened on the upper surface of the bed frame 2 corresponding to the position of the limiting pin 409 for positioning the guardrail 4.

[0024] As Figures 2-3As shown in the figure, in this embodiment, the protective tube 402 includes: a telescopic rod 406 and a receiving sleeve 407. The receiving sleeve 407 is fixedly connected to the rotating frame 403, the telescopic rod 406 is fixedly connected to the armrest 401, a limit bead is installed on the outer side of the telescopic rod 406, holes for positioning the limit bead are arrayed on the outer side of the receiving sleeve 407, a spring 408 is installed inside the receiving sleeve 407 at the lower end of the telescopic rod 406, and the telescopic rod 406 is fixedly connected to the receiving sleeve 407 through the spring 408.

[0025] The working principle of the present utility model is as follows: When in use, the overall limit mechanism 405 provided above the rotating frame 403 is positioned with the limit through holes on the upper surface of the bed frame 2, so as to perform protective treatment on both sides of the upper surface of the bed frame 2 for the overall guardrail 4. When it is necessary to assist a patient lying above the bed board 3 to turn over or wipe the body, the limit pin 409 is pulled upward as a whole. After the anti-detachment backing plate 411 outside the limit pin 409 compresses the positioning spring 410 and deforms, the rotating ear plate 404 on the lower surface of the rotating frame 403 is controlled to rotate in the rotating groove 201 on the upper surface of the bed frame 2. When the two guardrails 4 are rotated to be at the same horizontal plane as the nursing bed 1, the limit pin 409 inside the limit mechanism 405 will be inserted into the positioning hole 202. Therefore, the overall width dimension of the nursing bed 1 is increased. When assisting the patient to turn over, the situation where the patient falls due to the body turning can be prevented. At the same time, by pressing the limit bead on the outer side of the telescopic rod 406, the telescopic rod 406 is pushed outward as a whole under the action of the spring 408, and the limit bead is controlled to be clamped with holes at different positions on the outer side of the receiving sleeve 407, so as to realize the extension of the length of the protective tube and ensure the blocking and protection effects of the overall guardrail 4.
