Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more particularly to a linkage lifting medical bed. Background Art

[0002] At present, with the development of science, the level of medical care is also constantly improving. When treating and caring for patients, medical staff usually need to adjust the height of the patient's medical bed and the front and rear tilt angle of the medical bed. However, since medical staff will hold a lot of medical supplies in their hands, it is very cumbersome to manually adjust the state of the medical bed.

[0003] Therefore, how to provide a linkage lifting medical bed that frees hands and can quickly adjust the height and front and rear tilt angle of the medical bed is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0004] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent.

[0005] In view of this, the present invention provides a linkage lifting medical bed, which can control the lifting state of the medical bed and the front and rear tilting state of the medical bed by feet. It is not only convenient and quick to operate, but also the lifting and tilting state of the medical bed is very stable.

[0007] The first hydraulic lifting assembly is installed at the front end of the chassis;

[0008] The second hydraulic lifting assembly is installed at the rear end of the chassis;

[0009] The upper frame is installed on the top of the first hydraulic lifting assembly and the second hydraulic lifting assembly;

[0010] The first descending pedal and the second descending pedal are installed in parallel on the side wall of the base frame;

[0011] One end of the first descending link assembly is connected to the first descending pedal; the other end of the first descending link assembly is connected to the descending button of the first hydraulic lifting assembly;

[0012] One end of the second lowering link assembly is connected to the second lowering pedal; the other end of the second lowering link assembly is connected to the lowering button of the second hydraulic lifting assembly;

[0013] The ascending pedal is mounted on the base frame;

[0014] One end of the rising linkage connecting rod assembly is connected to the rising pedal; the other end of the rising linkage connecting rod assembly is respectively connected to the descending button of the first hydraulic lifting assembly and the descending button of the second hydraulic lifting assembly.

[0015] Beneficial effect: The medical bed of the present application has a compact structure and is easy to produce and install. A first descending pedal is provided, which is used to trigger the first descending link assembly by foot movement. The first descending link assembly triggers the descending button of the first hydraulic lifting assembly, thereby causing the hydraulic rod of the first hydraulic lifting assembly to compress and retract, and the head of the medical bed tilts downward, thereby realizing the reverse drooping head supine state of the medical bed. Furthermore, a second descending pedal is provided, which is used to trigger the second descending link assembly by foot movement. The second descending link assembly triggers the descending button of the second hydraulic lifting assembly, thereby causing the hydraulic rod of the second hydraulic lifting assembly to compress and retract, and the foot of the medical bed tilts downward, thereby realizing the drooping head supine state of the medical bed. Similarly, if the first descending pedal and the second descending pedal are triggered by foot movement at the same time, the overall descent of the medical bed can be realized, and the descent can be stopped by releasing the first descending pedal and the second descending pedal.

[0016] A rising pedal is provided for triggering the rising linkage link assembly by foot movement, and the rising linkage link assembly simultaneously triggers the rising buttons of the first hydraulic lifting assembly and the second hydraulic lifting assembly, thereby causing the hydraulic telescopic rod of the first hydraulic lifting assembly and the hydraulic telescopic rod of the second hydraulic lifting assembly to extend synchronously, thereby realizing the overall rising operation of the medical bed.

[0017] The medical bed of the present application can not only complete the overall rise and fall of the medical bed, but also realize the state change of the medical bed tilting upward and tilting downward. The hands of medical staff are freed, and the adjustment of the state of the medical bed can be completed by pedaling, which is very convenient and fast.

[0018] Preferably, in the above-mentioned linkage lifting medical bed, one end of the first descending pedal is located on the outer side of the side wall of the base frame; the other end of the first descending pedal is located on the inner side of the side wall of the base frame;

[0030] Beneficial effects: The setting structure of the descending connecting rod of the present application is ingenious, and the triggering of the descending button of the hydraulic lifting component is stably realized.

[0031] When the first descending pedal is stepped on with the foot, one end of the first descending pedal located on the outer side wall of the base frame drops downward, thereby driving one end of the first descending pedal located on the inner side wall of the base frame to lift upward; one end of the first descending pedal located on the inner side wall of the base frame lifts upward, thereby driving the first connecting rod to lift upward; the first connecting rod lifts upward, thereby driving the first driving shaft to rotate; the rotation of the first driving shaft thereby drives the first brake rod to move horizontally; the first brake rod moves horizontally thereby driving the first connecting member to move synchronously; the first connecting member moves, thereby driving the descending button of the first hydraulic lifting assembly connected to the connecting member to move synchronously, thereby realizing the triggering of the descending button.
