When the medical bed is laid on and leaves from the medical bed by a patient of the first elastic telescopic rod 1-2, the first elastic telescopic rod 1-2 stretches, when the first elastic telescopic rod 1-2 stretches, the hydraulic oil in the internal oil cavity can be pumped out, and further, the stretching speed of the first elastic telescopic rod 1-2 is limited due to the fact that the liquid is pumped out and put into operation in a relatively obvious time process, so that injuries to the patient caused by the fact that the stretching speed of the first elastic telescopic rod 1-2 is too high when the patient lays on and leaves from the medical bed are avoided.
As a further scheme of the invention, the first elastic telescopic rod 1-2 comprises a first hollow tube 1-2-1, a first sliding rod 1-2-2 is connected to the upper end of the first hollow tube 1-2-1 in a sealing sliding manner, a first pressing head 1-2-3 is fixedly connected to the upper end of the first sliding rod 1-2-2, a first piston 1-2-4 is fixedly connected to the lower end of the first sliding rod 1-2-2, the first piston 1-2-4 is connected with the inner wall of the first hollow tube 1-2-1 in a sealing sliding manner, a first spring 1-2-5 is fixedly connected to the lower end of the first piston 1-2-4, the lower end of the first spring 1-2-5 is fixedly connected with the bottom of the first hollow tube 1-2-1, the upper end of the first piston 1-2-4 is matched with the inner wall of the first hollow tube 1-2-1 to jointly form an oil cavity, and the first hollow tube 1-2-6 is connected to the first hollow tube 1-2-1 in a penetrating manner; the right side of the supporting frame 1-1 is fixedly connected with the first oil tank 2-1, the first communication pipe 1-2-6 is externally connected with a hard pipeline and is communicated with the left side wall of the first oil tank 2-1, the upper end of the first oil tank 2-1 is elastically sealed and slidingly connected with a first oil sealing plate 2-2, the first oil sealing plate 2-2 is slidingly connected with the left inner wall of the first oil tank 2-1, the first oil sealing plate 2-2 moves downwards to block the communicating position of the first communication pipe 1-2-6 and the first oil tank 2-1, and the right end of the first oil tank 2-1 is hermetically and slidingly connected with a first sliding plate 2-3.
When the medical bed is operated, (as shown in figure 10), when a human body presses the first elastic telescopic rod 1-2, the first pressure head 1-2-3 is subjected to downward movement by the pressing force, and then the first piston 1-2-4 is driven by the first sliding rod 1-2-2 to slide downwards relative to the first hollow tube 1-2-1, in the process, the first piston 1-2-4 presses the first spring 1-2-5, so that the first spring 1-2-5 is compressed (the first spring 1-2-5 is compressed to generate elastic force for supporting the weight of the human body and a reset power source of the first elastic telescopic rod 1-2 after the patient leaves a medical bed), in the downward movement process of the first piston 1-2-4, the volume in an oil cavity is increased to form negative pressure, and the downward movement speed of the first pressure head 1-2-3 is limited by matching with the elastic force of the first spring 1-2-5, so that the downward movement speed of the first pressure head 1-2-3 is prevented from being too fast, and injuries to the patient are generated; further, the negative pressure in the oil cavity sucks hydraulic oil from the first oil tank 2-1 through the first communication pipe 1-2-6 (after the hydraulic oil in the first oil tank 2-1 is sucked out, the first sliding plate 2-3 slides leftwards to reduce the volume of the first oil tank 2-1, so as to offset the sucked out part of the hydraulic oil in the first oil tank 2-1); after the patient lies well, the first elastic telescopic rods 1-2 are stabilized, the first oil sealing plate 2-2 is pressed down (as shown in fig. 4) to enable the communication part between the first communication pipe 1-2-6 and the first oil tank 2-1 to be plugged, further, the first pressure head 1-2-3 cannot move upwards (incompressibility of liquid; the outline of the medical bed is fixed), negative pressure is generated in the oil cavity when the first pressure head 1-2-3 moves downwards (firstly, the outline of the medical bed has certain elasticity to prevent injury to the patient due to excessive rigidity, secondly, the ground force required by a human body to overcome the negative pressure is larger, so that the outline stability of the medical bed can be ensured, and finally, after the first pressure head 1-2-3 moves downwards, the ground force generated by the human body overcomes the negative pressure is lost, the first pressure head 1-2-3 can reset under the action of the negative pressure force, and the outline stability of the medical bed is further ensured.
