[0024] In this embodiment: the connecting rod 202 is rotated to the right, the connecting rod 202 drives the rotating shaft 201 to rotate, and then drives the gear 8 to rotate clockwise, and then drives the spur rack 6 to slide to the left along the slide bar 5, and the spur rack 6 further drives the L-shaped rod 7 to slide to the left, and then drives the cover plate 13 to slide to the left, so that the cover plate 13 is separated from the top of the shell 401. When the connecting rod 202 rotates, it drives the railing 203 to move downward, and then drives the trigger rod 14 to move downward, and contacts the trigger firmware 403 at the upper end of the alarm 402, thereby triggering the alarm. The alarm 402 is electrically connected to the nurse station, so as to remind the nurse to check. When the guardrail 2 is lowered, the cover plate 13 of the synchronous belt is separated from the upper end of the shell 401. When the guardrail 2 is raised, the cover plate 13 closes the shell 401, which can prevent the patient from accidentally touching it, and the use effect is good.

[0025] As a technical optimization solution of the utility model, the left end faces inside the two protective shells 3 are fixedly connected with sleeves 11, the insides of the two sleeves 11 are slidably connected with pull rods 10, the right end faces of the two pull rods 10 are fixedly connected with blocks 9 matching the gear 8, and the outsides of the two sleeves 11 are sleeved with springs 12.

[0026] In this embodiment: when rotating the connecting rod 202, first pull the pull rod 10, and the pull rod 10 further drives the block 9 to slide to the left along the sleeve 11 and compresses the spring 12. At this time, the block 9 is separated from the gear 8, and the connecting rod 202 can be rotated. When the connecting rod 202 is rotated to vertical, release the pull rod 10, and the block 9 slides to the right under the elastic force of the spring 12, so that it is stuck on the gear 8, thereby fixing the gear 8, that is, fixing the guardrail 2.

[0027] As a technical optimization solution of the present utility model, the alarm device body 4 includes a shell 401 , an alarm 402 is installed inside the shell 401 , and a trigger firmware 403 is provided on the upper end surface of the alarm 402 .

[0028] In this embodiment, when the trigger firmware 403 is pressed down, the alarm 402 can be triggered, so that the alarm 402 can be triggered through the trigger rod 14 when the railing 203 is lowered.

[0029] As a technical optimization solution of the present invention, the outer walls of the two protective shells 3 are both provided with notches 15 .

[0030] In this embodiment, a notch 15 is provided on the outer wall of the protective shell 3 to facilitate the connecting rod 202 to pass through the protective shell 3 .

[0031] As a technical optimization solution of the present utility model, the longitudinal cross-section of the slide bar 5 is rectangular.

[0032] In this embodiment, the spur rack 6 is prevented from rotating by setting the longitudinal cross section of the slide bar 5 to be rectangular.

[0033] As a technical optimization solution of the present invention, the longitudinal cross-sections of the pull rod 10 and the sleeve 11 are both rectangular.

[0034] In this embodiment, the pull rod 10 and the sleeve 11 are configured to have a rectangular longitudinal cross section, thereby preventing the pull rod 10 and the clamping block 9 from rotating.

[0035] As a technical optimization solution of the present invention, both front and rear end surfaces of the bed body 1 are fixedly connected with a limit block 16 located on the left side of the leftmost connecting rod 202 .

[0036] In this embodiment, the limit block 16 located on the left side of the leftmost connecting rod 202 is fixedly connected to both the front and rear end surfaces of the bed body 1, so that the connecting rod 202 can only rotate to the right.

[0037] The working principle and use process of the utility model are as follows: when lowering the guardrail 2, first pull the pull rod 10, the pull rod 10 further drives the block 9 to slide to the left along the sleeve 11, and compresses the spring 12. At this time, the block 9 is separated from the gear 8, and the connecting rod 202 can be rotated. When the connecting rod 202 is rotated to the right, the connecting rod 202 drives the shaft 201 to rotate, and then drives the gear 8 to rotate clockwise, and then drives the spur rack 6 to slide to the left along the slide rod 5. The spur rack 6 further drives the L-shaped rod 7 to slide to the left, and then drives the cover plate 1 3 slides to the left, so that the cover plate 13 is separated from the top of the shell 401. When the connecting rod 202 rotates, the railing 203 is driven to move downward, and then the trigger rod 14 is driven to move downward, and contacts the trigger firmware 403 at the upper end of the alarm 402, thereby triggering the alarm. The alarm 402 is electrically connected to the nurse station, so as to remind the nurse to check. When the guardrail 2 is lowered, the cover plate 13 of the synchronous belt is separated from the upper end of the shell 401. When the guardrail 2 is raised, the cover plate 13 closes the shell 401, which can prevent the patient from accidentally touching it, and the use effect is good.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
