Referring to fig. 8, on the basis of the above embodiment, four horizontal support plates are fixedly arranged on the lower sides of four corners of the subframe, and the tops of the movable ends of the lifting rods are fixedly connected with the support plates;
a pressure spring is arranged between a support plate of the auxiliary frame and a horizontal plate of the bracket 6, and the pressure spring is sleeved outside the lifting rod;
a cavity is arranged in the fixed rod of the lifting rod, a movable rod of the lifting rod is sleeved with the inside of the fixed rod, a sealing gasket is arranged at the part of the movable rod, which is positioned in the fixed rod, and the sealing gasket is connected with the inner wall of the fixed rod in a sliding manner;
the bottom of the fixed rod is provided with a through hole, an exhaust valve is arranged at the through hole and is a one-way valve, and the exhaust valve is communicated with the inside of the extraction box 12 through an air pipe 11;
the extraction box 12 is arranged below the main frame 1, the extraction box 12 is communicated with the fixing rod of each lifting rod through an air pipe 11, an air outlet is formed in one side of the extraction box 12, and a valve is arranged at the air outlet.
Through this structure, can cooperate artifical or electronic air extractor, with the air outlet intercommunication of air extractor and exhaust chamber 12, then bleed, alright take out the air in the lifter to the movable rod descends. When the bed board 2 needs to be reset, only the valve needs to be opened, and the air pumping box 12 is enabled to intake air.
A bypass pipe 13 is arranged on one side of the fixed rod of the lifting rod, one end of the bypass pipe 13 is communicated with the inner cavity of the fixed rod, and the other end of the bypass pipe 13 extends to the side wall of the box body slot of the main frame 1, namely the other end of the bypass pipe 13 extends to the side wall of the box body slot close to the head and the tail of the bed;
the side wall of the box body slot is provided with an air inlet 131 corresponding to the bypass pipe 13, the air inlet 131 is provided with a spring plug 14, and the spring plug 14 comprises a ball head part 141 positioned at the outer side of the box body slot and a blocking part 142 connected with the ball head part 141;
a cylindrical channel is arranged between the air inlet 131 and the side wall of the box body slot, the spring plug 14 is positioned in the channel, the air inlet 131 is arranged at one end of the channel far away from the side wall of the box body slot, the blocking part 142 of the spring plug 14 is a cylinder, one end of the blocking part 142 facing the air inlet 131 is a spherical surface, a rubber layer is arranged at one side of the blocking part 142 contacting with the air inlet 131, the outer diameter of the blocking part 142 is smaller than that of the ball head part 141, a return spring 143 is arranged at the outer side of the blocking part 142, one end of the return spring 143 abuts against the ball head part 141, and the other end abuts against one side of the channel provided with the air inlet 131;
the inner diameter of the air inlet is smaller than the outer diameter of the blocking part 142; a plurality of grooves for air intake are uniformly distributed on the circumference of the periphery of the ball head part 141.
With this structure, when the sheet cassette 8 is inserted into the cassette slot, the ball portion 141 of the spring plug 14 is pushed by the sheet cassette 8 and moves toward the air inlet 131, and the blocking portion 142 of the spring plug 14 blocks the air inlet 131. When the bed sheet box 8 is taken out of the box body slot, the spring plug 14 is reset, air enters the fixed rod cavity of the lifting rod through the bypass pipe 13, and the lifting rod is reset. Through the structure, when the sickbed is needed to be used, the quick automatic reset of the bed board 2 can be directly realized along with the drawing-out of the bed sheet box 8.
In this structure, since there may be a case that the spring plug 14 is sucked by the negative pressure inside the lifter bar and cannot be ejected, the spring plug 14 may be used only as a cut-off valve for the air inlet end of the bypass pipe 13, that is, the air inlet 131 of the bypass pipe 13 extends to the outside of the main frame 1, only one branch of the pipeline passes through the position of the spring plug 14, and the moving direction of the spring plug 14 is perpendicular to the axial direction of the bypass pipe 13 along with the lateral movement of the spring plug 14, so that the bypass pipe 13 is cut off by the spring plug 14, and in this way, the negative pressure suction problem of the lifter bar can be avoided.
The main frame 1 is provided with a positioning pin, the subframe is provided with a pin hole, and when the bed board 2 is reset to the upper position of the main frame 1 along with the lifting of the lifting rod, the positioning pin is inserted into the pin hole, so that the subframe is stably positioned.
Example 5
On the basis of the above embodiment, the lower side of the bed tail end of the main frame 1 is fixedly provided with a vertical guide rail 101, the guide rail 101 is connected with a sliding block in a sliding manner, and the sliding block is rotatably connected with the rocker 3.
The slider is the cuboid, and the both sides and the laminating of guide rail 101 inner wall and sliding connection of slider.
Through guide rail 101 and slider, play the supporting role of bed tail end to rocker 3, because compare with traditional sick bed, the bed board 2 of this scheme is movable, and consequently rocker 3 also need follow the bed board movable, through setting up guide rail and slider to guarantee the stability that rocker 3 rocked.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
