[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a hospital bed.

[0030] Reference Figure 1 and Figure 2 The hospital bed includes a footboard extension mechanism, which includes a bed frame 1, a footboard 2, and a limiting component 3. The bed frame 1 is placed horizontally on the ground, and the footboard 2 is slidably connected to the bed frame 1 in the direction of the length of the bed frame 1.

[0031] Reference Figure 2and Figure 3 The limiting component 3 includes a limiting plate 31, a pressing plate 32, a limiting rod 33, and an elastic element 34. The limiting plate 31 is fixedly connected to the bed frame 1. A rectangular first limiting groove 311 and a second limiting groove 312 are provided on the lower side of the limiting plate 31. The first limiting groove 311 and the second limiting groove 312 are spaced apart along the length direction of the limiting plate 31.

[0032] The upper side of the pressing plate 32 is rotatably connected to the inner side of the footboard 2. One end of the limiting rod 33 is fixedly connected to the pressing plate 32, and the other end is arranged in an "L" shape and matches the limiting plate 31. In this embodiment, the elastic element 34 is a spring. One end of the elastic element 34 is fixedly connected to the footboard 2, and the other end elastically abuts against the pressing plate 32 to drive the pressing plate 32 to rotate, so that the lower side of the pressing plate 32 moves away from the footboard 2, and the end of the limiting rod 33 away from the pressing plate 32 is engaged and limited in the first limiting groove 311 or the second limiting groove 312.

[0033] In practical applications, in the initial state, the limiting rod 33 is locked in the first limiting groove 311. When it is necessary to extend the hospital bed, the pressing plate 32 is pressed, causing the pressing plate 32 to rotate and compress the elastic element 34. The limiting rod 33 rotates under the drive of the pressing plate 32 to disengage from the first limiting groove 311. At this time, the foot of the bed 2 is slid outward a certain distance. The pressing plate 32 is reset under the drive of the elastic element 34 and locked in the second limiting groove 312 to limit the sliding of the foot of the bed 2. The operation is simple and convenient, thus facilitating the extension of the length of the hospital bed.

[0034] In some embodiments, the lower side of the pressing plate 32 is bent toward the side away from the foot of the bed 2. When the pressing plate 32 is pressed, force is applied to the bent part of the pressing plate 32 so as to rotate the pressing plate 32, thereby facilitating the release of the locking between the limiting rod 33 and the first limiting groove 311 or the second limiting groove 312, and thus facilitating the extension of the length of the hospital bed.

[0035] In some embodiments, the limiting component 3 further includes a rotating shaft 35, which is rotatably connected to the foot of the bed 2. The pressing plate 32 is clamped to the rotating shaft 35 and can rotate with the rotating shaft 35, so that the pressing plate 32 is rotatably connected to the foot of the bed 2. Furthermore, the rotating shaft 35 and the foot of the bed 2 are detachably connected to facilitate the installation of the limiting component 3 and the foot of the bed 2.

[0036] In some embodiments, the limiting rod 33 is clamped to the rotating shaft 35, so that the limiting rod 33 is driven to rotate by the pressing plate 32, thereby improving the stability of the rotation of the limiting rod 33 and ensuring stability during the process of extending the length of the hospital bed.

[0037] In some embodiments, the limiting component 3 further includes a retaining spring 36. A rotating shaft 35 passes through the foot of the bed 2, with one end of the rotating shaft 35 abutting against the foot of the bed 2. The retaining spring 36 is engaged with the other end of the rotating shaft 35, thereby achieving a detachable connection between the rotating shaft 35 and the foot of the bed 2. This structure is simple and facilitates the installation and removal of the rotating shaft 35. The rotating shaft 35 passes through the pressing plate 32 and the limiting rod 33, ensuring that both the pressing plate 32 and the limiting rod 33 are securely held in place by the rotating shaft 35. Thus, the pressing plate 32 and the limiting rod 33 are installed simultaneously with the rotating shaft 35, facilitating the installation of the limiting component 3 and the foot of the bed 2.

[0038] In some embodiments, the limiting component 3 further includes a limiting post 37, which is fixedly connected to one end of the pressing plate 32 near the elastic member 34 and is movably inserted through the foot of the bed 2 to limit the rotation of the pressing plate 32, thereby improving the stability of the rotation of the pressing plate 32.

[0039] In some embodiments, the elastic element 34 is sleeved on the limiting post 37 to limit the deformation of the elastic element 34, so as to avoid excessive bending of the elastic element 34 and damage, thereby improving the service life of the elastic element 34.

[0040] Reference Figure 4 In some embodiments, the foot of the bed 2 includes a footboard 21, a footboard 22, and latches 23. The footboard 22 is detachably connected to the footboard 21 for easy use. The lower end of the footboard 22 is inserted into the footboard 21, and the latches 23 are fixedly connected to the footboard 21. The number of latches 23 is the same as the number of parts where the footboard 22 is inserted into the footboard 21. By rotating the latches 23, they engage in the slots (not marked in the figure) where the footboard 22 is inserted into the footboard 21, thus restricting the movement of the footboard 22 and achieving a detachable connection between the footboard 21 and the footboard 22.

[0041] The implementation principle of this embodiment is as follows: In practical application, in the initial state, the limiting rod 33 is locked in the first limiting groove 311. When it is necessary to extend the hospital bed, the pressing plate 32 is pressed, causing the pressing plate 32 to rotate and compress the elastic element 34. The limiting rod 33 rotates under the drive of the pressing plate 32 to disengage from the first limiting groove 311. At this time, the foot of the bed 2 is slid outward a certain distance. The pressing plate 32 is reset under the drive of the elastic element 34 and locked in the second limiting groove 312 to limit the sliding of the foot of the bed 2. The operation is simple and convenient, thereby facilitating the extension of the length of the hospital bed.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
