Because the protection mechanism 21 is also included, the protection mechanism 21 comprises a support plate 211, a movable rod 212, a compression cylinder 213, a piston 214, an air inlet pipe 215, a one-way valve 216 and an air outlet pipe 217, the support plate 211 is installed on the upper portion of the inner side surface of the left and right support legs 5, the left support plate 211 is positioned above the guide rod 11, the compression cylinder 213 is installed on the right side of the top of the left support plate 211 and the left side of the top of the right support plate 211, the piston 214 is arranged in the compression cylinder 213, the movable rod 212 is installed in the middle of the top of the piston 214, the top end of the left movable rod 212 penetrates through the middle of the top of the left compression cylinder 213 and is connected with the left side of the bottom of the frame 3, the top end of the right movable rod 212 penetrates through the middle of the top of the right compression cylinder 213 and is connected with the right side of the bottom of the frame 3, the, the air outlet pipe 217 is communicated with the compression cylinder 213, the air outlet pipe 217 and the air inlet pipe 215 are both provided with one-way valves 216, when medical personnel pull the seat 18 to move rightwards, the frame body 3 moves upwards and simultaneously drives the movable rod 212 to move upwards, the movable rod 212 moves upwards to drive the piston 214 to move upwards, the piston 214 moves upwards to pump air into the compression cylinder 213 through the air inlet pipe 215, and when the frame body 3 moves upwards to a proper position to stop moving, the piston 214 also stops moving, and the medical personnel can feed patients. After the meal is fed, the medical staff pushes the seat 18 back to the original position, the frame 3 moves downwards and drives the piston 214 to move downwards through the movable rod 212, the piston 214 pushes out the air in the compression cylinder 213 through the air outlet pipe 217, and the air is discharged more slowly because the air outlet pipe 217 is smaller than the air inlet pipe 215. When the frame 3 moves downward and returns to the original position, the piston 214 stops moving. Thus, the frame 3 can move downwards more slowly, and the frame 3 is prevented from moving downwards too fast to damage the connecting rod 10.
Because still including 7 type pole 22, support 23 and second pulley 24, 7 type pole 22 is installed on horizontal pole 6 top right side, and 7 type pole 22 right-hand member installs support 23, and second pulley 24 is installed to support 23 bottom, and second pulley 24 is located first pulley 7 top and contacts with first stay 14, and when medical personnel promoted seat 18 and moved the recovery to the normal position left, first stay 14 was loosened, and then second pulley 24 plays the guide effect to first stay 14, breaks away from on preventing first stay 14 when relaxing with first pulley 7.
Because the device also comprises a placing device 25, the placing device 25 comprises a track 253, a guide wheel 254, a placing frame 255, a first spring 256, a vertical plate 257, a third pulley 258 and a second pull wire 259, the middle of the lower part of the seat 18 is provided with a mounting groove 251, the lower part of the right side of the seat 18 is provided with a through hole 252, the through hole 252 is communicated with the mounting groove 251, the track 253 is horizontally arranged at the bottom in the mounting groove 251, the guide wheel 254 is arranged on the track 253, the guide wheel 254 is in sliding fit with the track 253, the placing frame 255 is arranged on the guide wheel 254, the first spring 256 is connected between the upper side and the lower side of the outer left side of the placing frame 255 and the upper side and the lower side of the inner left side of the mounting groove 251, the vertical plate 257 is arranged on the outer right side of the placing frame 255, the vertical plate 257 is positioned on the right side of the seat 18, the lower part of the right side of the seat 18 is provided, when the medical staff pulls the seat 18 to move rightwards, the seat 18 pulls the guide wheel 254 to move rightwards through the second pull wire 259, the guide wheel 254 moves rightwards to drive the placing frame 255 to move rightwards, the first spring 256 is stretched, the placing frame 255 moves rightwards to be located outside the mounting groove 251, when the seat 18 moves rightwards to a proper position, the user can sit on the seat 18, and the medical staff can place articles into the placing frame 255. When the article is needed, the article can be taken out of the placing frame 255. After the meal is fed, the medical staff pushes the seat 18 to move leftwards to return to the original position, the second pulling wire 259 is loosened, and the placing frame 255 moves leftwards to be positioned in the mounting groove 251 to return to the original position due to the action of the first spring 256. Therefore, the articles are convenient to place and use.
Because the device also comprises a connecting rod 26, a fixed block 27, a sliding rod 29, a contact plate 30, a second spring 31, a u-shaped fixture block 32 and a fixed rod 33, the connecting rod 26 is arranged between the lower parts of the inner side surfaces of the front and rear side supporting legs 5 on the right side, the connecting rod 26 is positioned below the sliding rail 15, the fixed block 27 is arranged in the middle part of the left side of the connecting rod 26, the guide hole 28 is formed in the left side of the fixed block 27, the sliding rod 29 is arranged in the guide hole 28, the u-shaped fixture block 32 is arranged at the top end of the sliding rod 29, the u-shaped fixture block 32 is positioned below the sliding rail 15 and matched with the sliding rail, the contact plate 30 is arranged at the bottom end of the sliding rod 29, the second spring 31 is connected between the top of the contact plate 30 and the bottom of the fixed block 27, the fixed rod 33 is arranged at the right side, under the action of the second spring 31, the slide bar 29 moves upward to drive the u-shaped latch 32 to move upward, the u-shaped latch 32 moves upward to contact with the slide rail 15 and is located on the left side of the second slider 16, and the u-shaped latch 32 blocks the second slider 16.
