[0003] In the prior art, most of the existing guardrails of nursing beds adopt a fixed installation method, or although they can be adjusted to a certain extent, the operation is complex, and the occupied space is large after being stored. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the fixed or semi-fixed guardrails on traditional nursing beds lack flexibility in use, cannot meet the personalized needs of different users, and are difficult to effectively store when the guardrails are not needed, occupying space.

[0005] To achieve the above object, the technical solution provided by the utility model is as follows:

[0006] A novel folding guardrail, including a guardrail, and further including a connecting plate and a folding mechanism. The guardrail is set in an inverted U shape. The folding mechanism is connected to both ends of the guardrail. Two connecting plates are respectively connected to the folding mechanisms at both ends of the guardrail. Bolts are inserted through the connecting plates for connecting the connecting plates to the lower end of the nursing bed.

[0007] Further, the folding mechanism includes a housing and a connecting ring. The connecting ring is fixedly connected to the connecting plate. The housing is fixedly connected to the lower end of the guardrail. The connecting ring is rotatably connected inside the housing. A connecting shaft is fixedly connected inside the housing.

The arc-shaped limiting plate is slidably adapted to the through hole.

[0009] Further, connecting rods are symmetrically and fixedly connected to both sides of the end of the guardrail. Limiting pieces are fixedly connected to the ends of the connecting rods. Arc-shaped sliding rails are provided on both sides of the housing. The connecting rods are slidably adapted to the sliding rails inside. The connecting rods on the outside of the guardrail extend out of the arc-shaped sliding rails on the outside of the housing. Threaded rings are rotatably sleeved on the connecting rods on the outside of the guardrail. Threaded grooves are provided at both ends of the arc-shaped sliding rails on the outside of the housing. The threaded rings are threadedly adapted to the threaded grooves. One end of the threaded ring is fixedly connected to a knob ring.

[0010] Furthermore, the arc-shaped sliding groove, the arc-shaped limiting plate, and the sliding rail are all set as three-quarter circumferential arcs.

[0011] Furthermore, one end of the connecting plate is symmetrically and fixedly connected with a connecting piece, and the connecting piece is clamped and fixedly connected to both sides of the housing.

[0024] As Figure 1-7As shown in the figure, a new type of folding guardrail 2 includes a guardrail 2, a connecting plate 1 and a folding mechanism 3. The guardrail 2 is in an inverted U shape. The folding mechanism 3 is connected to both ends of the guardrail 2. Two connecting plates 1 are respectively connected to the folding mechanisms 3 at both ends of the guardrail 2. A bolt 102 is inserted through the connecting plate 1 for connecting the connecting plate 1 to the lower end of the nursing bed.

[0025] As Figure 3 , 6 shown in the figure, in order to enable the folding and rotational connection between the connecting plate 1 and the guardrail 2, the folding mechanism 3 includes a housing 301 and a connecting ring 206. The connecting ring 206 is fixedly connected to the connecting plate 1. The housing 301 is fixedly connected to the lower end of the guardrail 2. The connecting ring 206 is rotatably connected inside the housing 301. A connecting shaft 306 is fixedly connected inside the housing 301. The connecting ring 206 is rotatably connected to the connecting shaft 306.

[0026] As Figure 3-5 shown in the figure, in order to improve the rotational stability of the guardrail 2 on the housing 301, a through hole 203 is provided between the guardrail 2 and the connecting ring 206. The housing 301 is provided with an arc-shaped sliding groove 302. The end of the guardrail 2 is rotatably connected inside the arc-shaped sliding groove 302. An arc-shaped limiting plate 303 is fixedly connected in the arc-shaped sliding groove 302. The arc-shaped limiting plate 303 is slidably adapted to the through hole 203.

[0027] As Figure 4 , 5 shown in Figures 7, in order to fix the guardrail 2 after rotation, connecting rods 204 are symmetrically and fixedly connected to both sides of the end of the guardrail 2. Limiting pieces 205 are fixedly connected to the ends of the connecting rods 204. Arc-shaped sliding rails 304 are provided on both sides of the housing 301. The connecting rods 204 are slidably adapted inside the sliding rails. The connecting rods 204 on the outside of the guardrail 2 extend out of the arc-shaped sliding rails 304 on the outside of the housing 301. A threaded ring 307 is rotatably sleeved on the connecting rod 204 on the outside of the guardrail 2. Threaded grooves 305 are provided at both ends of the arc-shaped sliding rail 304 on the outside of the housing 301. The threaded ring 307 is threadedly adapted to the threaded groove 305. A knob ring 308 is fixedly connected to one end of the threaded ring 307.

[0028] As Figure 5 shown in the figure, the arc-shaped sliding groove 302, the arc-shaped limiting plate 303 and the sliding rail are all three-quarter circumferential arcs, thereby limiting the rotation range of the guardrail 2.

[0029] As Figure 3 shown in the figure, connecting pieces 101 are symmetrically and fixedly connected to one end of the connecting plate 1. The connecting pieces 101 are clamped and fixedly connected to both sides of the housing 301, thereby improving the connection stability between the connecting plate 1 and the housing 301.

[0030] As Figure 4As shown, a fixed cross plate 201 is fixedly connected in the guardrail 2, and a number of fixed vertical plates 202 are fixedly connected between the fixed cross plate 201 and the guardrail 2, thereby improving the stability of the guardrail 2.

[0031] When the present utility model is in use, the connecting plate 1 is connected to the lower end of the nursing bed through the bolt 102. When it is necessary to support the guardrail 2 on the nursing bed, the guardrail 2 is rotated. Then, both ends of the guardrail 2 rotate in the arc-shaped sliding groove 302. At the same time, the through hole 203 slides on the arc-shaped limiting plate 303, and the connecting ring 206 slides on the connecting shaft 306 in the housing 301. The connecting rods 204 fixedly connected to both sides of both ends of the guardrail 2 slide to the ends in the arc-shaped sliding rails 304 on both sides of the housing 301. At this time, the guardrail 2 and the connecting plate 1 are perpendicular to each other. The knob ring 308 is rotated, thereby driving the threaded ring 307 to be threadedly connected to the threaded groove 305 at one end of the arc-shaped sliding rail 304, thereby realizing the fixation of the guardrail 2. Thus, the nursing bed can be assisted by the guardrail 2. When the guardrail 2 is not needed, only the threaded ring 307 is rotated and pulled out to the threaded groove 305 at one end of the arc-shaped sliding rail 304, and the guardrail 2 is rotated until the guardrail 2 rotates to the lower side of the connecting plate 1 at the lower end of the nursing bed. At this time, the connecting rod 204 slides along the arc-shaped sliding rail 304 to the other end of the sliding rail, and then the threaded ring 307 is rotated and threadedly connected into the threaded groove 305 at the other end of the arc-shaped sliding rail 304 to realize the folding and fixation of the guardrail 2.

[0032] In summary: In the embodiment of the present utility model, the connecting plate 1 is connected to the nursing bed through the bolt 102. Then, the folding of the guardrail 2 can be controlled through the folding mechanism 3. When in use, the guardrail 2 is rotated to the vertical state and fixed. When not in use, the guardrail 2 can be rotated to be flush with the connecting plate 1, and then the guardrail 2 is stored under the nursing bed. The operation is simple and convenient, and the practicability is strong.

[0033] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
