Referring to fig. 1 to 4, the present invention provides a hospital bed structure. The sickbed structure is applied to medical equipment, and is matched with medical instruments of the medical equipment for use so as to meet the use requirements of different occasions of medical staff, such as operations, radiotherapy, imaging and the like. The sickbed structure can be obliquely arranged, the inclination angle can be changed in a large range, and medical workers can adjust the inclination angle according to actual use requirements, so that the application occasions are increased.

In one embodiment, the hospital bed structure includes a bed board 100 and a gear transmission mechanism 200. The bed board 100 has a first direction and a second direction perpendicular to each other. The gear transmission mechanism 200 connects the top board 100 and the base 234, and the gear transmission mechanism 200 can drive the top board 100 to tilt in the first direction and/or the second direction.

The bed plate 100 is a flat plate for supporting a patient. As shown in fig. 1, the bed board 100 is rectangular. The first direction and the second direction perpendicular to each other are provided on the plane where the bed board 100 is located. Illustratively, the first direction is a length direction of the bed board 100, the second direction is a width direction of the bed board 100, and a dimension of the bed board 100 in the length direction is larger than a dimension of the bed board 100 in the width direction, and the patient is positioned on the bed board 100 in the length direction of the bed board 100.

It can be understood that the current sickbed inclination is realized by the push rod, in particular, the inclination of the bed board is realized by the extension and the shortening of the push rod. However, when the push rod is used for adjusting the inclination angle of the sickbed, the adjustment angle of the sickbed is small, and the use requirements of different occasions cannot be met. Therefore, the sickbed structure of the invention adds the gear transmission mechanism 200 below the bed board 100. The gear transmission mechanism 200 is in transmission connection with the bed plate 100, and the gear transmission mechanism 200 can drive the bed plate 100 to move, so that the bed plate 100 tilts. The gear transmission mechanism 200 can have a large movement space, so that the bed board 100 has a large range of inclination angle, thereby satisfying the use requirements of different occasions and facilitating the use of medical staff.

Specifically, the gear transmission mechanism 200 may drive the bed plate 100 to tilt only along the first direction, may also drive the bed plate 100 to tilt only along the second direction, and may also drive the bed plate 100 to tilt along the first direction and the second direction. Medical personnel can control the motion of gear drive mechanism 200 according to actual user demand to adjust the inclination of bed board 100 in required direction, satisfy actual user demand. Moreover, when the gear transmission mechanism 200 drives the bed board 100 to incline, the spatial angle of the patient can be adjusted, so that the focus position of the patient can meet the requirements of treatment and the like, and the treatment effect and the like are improved.

After the hospital bed structure of the above embodiment is adopted, the gear transmission mechanism 200 can drive the bed board 100 to move, so that the bed board 100 tilts. The gear transmission mechanism 200 has a large-angle stroke, so that large-angle adjustment of the inclination of the sickbed can be realized, and the problem of small inclination angle of the existing push rod mode is effectively solved, so that the inclination angle of the bed board 100 can be changed in a large range, and different inclination requirements can be met. Moreover, the gear transmission mechanism 200 can drive the bed board 100 to incline along the first direction and/or the second direction, so as to meet the requirement of the bed board 100 on inclination in different directions, increase the application occasions and facilitate the use of medical staff. Moreover, the gear transmission mechanism 200 has strong bearing capacity, can bear heavier load and improves the bearing capacity of the sickbed structure.

Of course, in other embodiments of the present invention, the positions of the first direction and the second direction may be interchanged. That is, the first direction is the width direction of the bed plate 100, and the second direction is the length direction of the bed plate 100.
