Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 A fall prevention bed safety device includes a bed frame 1 and six guard plates 2, with a safety mechanism 3 provided between the bed frame 1 and the six guard plates 2. The safety mechanism 3 includes 12 fixed seats 301, which are respectively fixedly installed on both sides of the bed frame 1. A limiting shaft 302 is fixedly installed through the fixed seat 301 and the guard plate 2. A first spring 303 is installed between the limiting shaft 302 and the guard plate 2. Limiting grooves 304 are opened on the upper and lower sides of the fixed seat 301. Two limiting posts 305 are fixedly installed on the inner wall of the guard plate 2.

[0025] The guard plate 2 is rotatably connected to two fixed seats 301 via a limiting shaft 302. The guard plate 2 is slidably and rotatably mounted on the limiting shaft 302. The limiting groove 304 is adapted to the limiting post 305, and the two limiting grooves 304 are connected in a straight line perpendicular to the upper surface of the bed 1. The first spring 303 is rotatably mounted on the guard plate 2 and the limiting shaft 302 respectively. By controlling the guard plate 2 to slide on the limiting shaft 302, the limiting post 305 is pulled out from one limiting groove 304. At this time, the guard plate 2 can be rotated to make the limiting post 305 correspond to the other limiting groove 301. On one side of 04, further loosening the guard plate 2 allows it to move along the limiting shaft 302 under the support of the first spring 303 and be fixed by the limiting groove 304 and the limiting post 305. During use, the upper limit post 305 of the guard plate 2 can be controlled to embed into the limiting groove 304 on the upper and lower sides of the fixing seat 301 as needed, so that the guard plate 2 is in a protective or retracted state. The operation is simple and provides protection, making it more convenient for patients to get on and off the bed. There are three guard plates 2 on each side of the bed 1, and different numbers of guard plates 2 can be opened according to the patient's physique or usage habits.

[0026] Example 2

[0027] See Figure 4 and Figure 5 The bed frame 1 is provided with a gripping mechanism 4 on both sides. The gripping mechanism 4 includes two fixed frames 401, which are fixedly installed on both sides of the bed frame 1. Two grip rods 402 are slidably installed in parallel through the fixed frames 401. Two brackets 403 are fixedly installed in parallel on the lower side of the fixed frames 401. A positioning column 404 is slidably installed through the brackets 403 and the fixed frames 401. A second spring 405 is fixedly installed between the positioning column 404 and the bracket 403. Several positioning grooves 406 are opened in parallel on one side of the grip rods 402.

[0028] Two U-shaped grooves are arranged side by side on the upper side of the fixed frame 401, and the handle 402 is adapted to the U-shaped grooves. The U-shaped grooves are used to hide the handle 402 to prevent the handle 402 from protruding from the bed 1 and obstructing the patient's movement. The handle 402 is located between every two guardrails 2. The positioning post 404 is adapted to the positioning groove 406. Several positioning grooves 406 are equidistantly arranged on one side of the handle 402. When in use, when the guardrail 2 is retracted and the patient needs to sit on the edge of the bed, the positioning post 404 is pulled to disengage it from the positioning groove 406. At this time, the handle 402 can slide on the fixed frame 401. After the extension height of the handle 402 is adjusted, the positioning post 404 is released and embedded into the adjacent positioning groove 406 under the support of the second spring 405 to fix the handle 402. At this time, the handle 402 is used to assist the patient in sitting up and to prevent the patient from slipping due to the lack of handrails on the bed 1.

[0029] In actual operation, by controlling the guard plate 2 to slide on the limiting shaft 302, the limiting post 305 is pulled out from the limiting groove 304 on one side. At this time, the guard plate 2 can be rotated so that the limiting post 305 corresponds to the other limiting groove 304. Further loosening the guard plate 2 allows the guard plate 2 to move along the limiting shaft 302 under the support of the first spring 303 and be fixed by the limiting groove 304 and the limiting post 305. When in use, the upper limit post 305 of the guard plate 2 can be inserted into the limiting groove 304 on the upper and lower sides of the fixing seat 301 according to the needs, so that the guard plate 2 is in the protective or retracted state. The operation is simple and makes it more convenient for patients to get on and off the bed while providing protection.

[0030] When the patient needs to sit on the edge of the bed after the guardrail 2 is retracted, the positioning post 404 is pulled to disengage it from the positioning slot 406. At this time, the grip 402 can be slid on the fixing frame 401. After the extension height of the grip 402 is adjusted, the positioning post 404 is released and embedded into the adjacent positioning slot 406 under the support of the second spring 405, thus fixing the grip 402. At this time, the grip 402 is used to assist the patient in sitting up and avoid the patient slipping and falling due to the lack of handrails on the bed 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
