A connecting rod 14 which is obliquely arranged is hinged between the movable plate 11 and the bed plate 33, a first hinging seat 15 is fixedly arranged at the top of the movable plate 11 through bolts, a second hinging seat 16 is fixedly arranged at the bottom of the bed plate 33 through bolts, the second hinging seat 16 is positioned at the front side of the first hinging seat 15, the height of the second hinging seat 16 is higher than that of the first hinging seat 15, two ends of the connecting rod 14 are respectively hinged on the first hinging seat 15 and the second hinging seat 16, and the movable plate 11 drives the bed plate 33 to rotate around the pin shaft 7 through the connecting rod 14 when sliding forwards and backwards along the sliding rod 12.
In the initial state, as shown in fig. 1, the bed plate 33 is in a horizontal state; after the patient lies prone on the bed plate 33 and is fixed through the fixing belt assembly, medical staff drives the movable plate 11 to slide forwards through the adjusting mechanism, as shown in fig. 6, when the movable plate 11 slides forwards, the connecting rod 14 drives the bed plate 33 to rotate upwards around the pin shaft 7, so that the rear end of the bed plate 33 is lifted, the patient can easily overturn to a body position with the height of the head and the foot along with the bed plate 33, and the medical staff can enable the blood in the lung of the patient and the bronchus of the trachea to flow out through the mouth rapidly through means such as back beating. In addition, the outer side of the slide bar 12 is also integrally formed with an annular baffle ring 17, and when the movable plate 11 slides forward and drives the slide seat 13 at the forefront to abut against the baffle ring 17, the bed plate 33 rotates upward to a vertical state, so that the bed plate 33 is limited to rotate within ninety degrees.
On the contrary, the movable plate 11 is driven to slide backwards through the adjusting mechanism, and when the movable plate 11 slides backwards, the bed plate 33 is driven to rotate backwards and downwards around the pin shaft 7 through the connecting rod 14, so that the rear end of the bed plate 33 is lowered until the rear end of the bed plate 33 is attached to the connecting plate 4 of the bed frame 1 to restore the horizontal state again, and the rescue bed is conveniently used for rescue work such as common cardiopulmonary resuscitation.
As shown in fig. 1, the front end of the bed plate 33 between the two limiting plates 8 is provided with an arc-shaped notch 18 to prevent vomit of a patient from being contaminated on the bed plate 33.
As shown in fig. 2, two pins 19 extending from left to right are oppositely arranged at the bottom of the front end of the bed plate 33, two sliding sleeves 20 are sleeved on the pins 19, the sliding sleeves 20 are fixedly arranged at the bottom of the bed plate 33 through bolts, a deflector rod 21 positioned between the two sliding sleeves 20 is welded on the pins 19, insertion holes 22 matched with the corresponding pins 19 are respectively arranged on the two longitudinal beams 2, and when the pins 19 are inserted into the corresponding insertion holes 22, the bed plate 33 is in a horizontal state. When the bed plate 33 is in a horizontal state, the bolt 19 is inserted into the jack 22 to limit the rotation of the bed plate 33, so that the state of the bed plate 33 is kept stable.
As shown in fig. 5, the adjusting mechanism comprises a rack 23 fixedly installed at the bottom of the movable plate 11 through a bolt, the rack 23 extends back and forth, a transverse shaft 24 extending left and right is rotatably installed in the box 5 through a bearing, a gear mechanism matched with the rack 23 is arranged on the transverse shaft 24, the gear mechanism comprises a first gear 25 fixedly installed on the transverse shaft 24, and the first gear 25 is meshed with the rack 23. The cross shaft 24 is fixedly provided with a worm wheel 26, the inside of the box 5 is rotatably provided with a longitudinal shaft 27 extending forwards and backwards through a bearing, the longitudinal shaft 27 is provided with a worm 28 meshed with the worm wheel 26, and the rear end of the longitudinal shaft 27 extends to the outer side of the box 5 and is fixedly provided with a crank 29.
The crank 29 is rotated to drive the longitudinal shaft 27 and the worm 28 to rotate, the worm 28 acts on the worm wheel 26 to drive the transverse shaft 24 and the first gear 25 to rotate, and the first gear 25 acts on the rack 23 to drive the movable plate 11 to move forwards and backwards, so that the angle of the bed plate 33 is adjusted. When the longitudinal axis 27 and the worm 28 are at rest, the worm 28 locks the worm gear 26 to limit rotation of the transverse axis 24 and the first gear 25, maintaining the angle of the bed 33 fixed.
Example 2:
As shown in fig. 7, this embodiment is different from embodiment 1 in that the gear mechanism includes a second gear 30 rotatably mounted on the cross shaft 24 through a bearing, the second gear 30 is engaged with the rack 23, a ratchet 31 is fixedly mounted on the cross shaft 24, a pawl 32 matched with the ratchet 31 is mounted on one side of the second gear 30, the pawl 32 is rotatably mounted on one side of the second gear 30 through a small shaft extending from left to right, a torsion spring for making the pawl 32 ride on the ratchet 31 is further sleeved on the small shaft, and the ratchet 31 cooperates with the pawl 32 to restrict the rear end of the bed plate 33 from rotating downward.
Specifically, after the patient is fixed by the fixing belt assembly, the medical staff can directly turn over the rear end of the bed board 33 upwards, so that the patient can be quickly adjusted to a position with a height of the head and the feet, and the rescue time can be saved. When the longitudinal axis 27 and the worm 28 are in a static state, the bed plate 33 drives the movable plate 11 to slide forwards when rotating upwards, the movable plate 11 drives the second gear 30 to rotate forwards around the transverse axis 24 through the rack 23, the ratchet wheel 31 does not block the pawl 32 from rotating forwards along with the second gear 30, the ratchet wheel 31 blocks the pawl 32 from rotating backwards along with the second gear 30, and therefore the rear end of the bed plate 33 is prevented from rotating downwards under the action of gravity when in an inclined state.
In this embodiment, the angle of the bed plate 33 can also be adjusted by rotating the crank 29. Specifically, when the crank 29 is rotated in the forward direction to drive the longitudinal shaft 27 and the worm 28 to rotate in the forward direction, the worm 28 acts on the worm wheel 26 to drive the transverse shaft 24 and the ratchet wheel 31 to rotate forward, the ratchet wheel 31 acts on the pawl 32 to drive the second gear 30 to synchronously rotate forward, the second gear 30 acts on the rack 23 to drive the movable plate 11 to move forward, and the bed plate 33 is further rotated upward; conversely, when the crank 29 is rotated reversely to drive the vertical shaft 27 and the worm 28 to rotate reversely, the worm 28 acts on the worm wheel 26 to drive the horizontal shaft 24 and the ratchet wheel 31 to rotate backwards, and meanwhile, the bed plate 33 rotates downwards under the action of gravity to drive the pawl 32 and the second gear 30 to synchronously rotate backwards along with the ratchet wheel 31.
The foregoing has shown and described the basic principles, main features and advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
