When the piston rod of the first cylinder 30 and the piston rod of the second cylinder 32 shrink , the lower end of the front lifting arm 23 moves backward along the track of the chute 28, the vertical distance between the upper end and the lower end of the front lifting arm 23 becomes smaller, and the height of the front part of the rear lifting arm 25 gradually decreases, thereby realizing the parallelism between the front and rear ends of the right bed board 8 Descending, when the piston rod of the first cylinder 30 and the piston rod of the second cylinder 32 were ejected, the front and rear ends of the right bed board 8 would rise in parallel to ensure the stability of the right bed board 8 when lifting.

The existence of the first motor 35 and the second motor 40 can play the effect of auxiliary lifting. The first motor 35 and the second motor 40 start synchronously when the first cylinder 30 and the second cylinder 32 run. When the first motor 35 starts , the motor shaft of the first motor 35 can drive the first gear 39 to rotate, and the first gear 39 meshes with the first internal teeth 37, which can effectively realize the rotation of the front end of the rear lifting arm 25. When the second motor 40 starts , the motor shaft of the second motor 40 can drive the second gear 44 to rotate, and the second gear 44 meshes with the second internal tooth 42, which can effectively realize the rotation of the rear end of the main arm 24, and when the right bed board 8 drops to the limit, The main arm 24, the front lifting arm 23, and the rear lifting arm 25 are all parallel to the right bed board 8. At this moment, the first cylinder 30 is opposite to the front lifting arm 23, and the second cylinder 32 is parallel to the rear lifting arm 25. In this case, Even if the piston rod of the first cylinder 30 is pushed out, it is also difficult to push the front lifting arm 23, and even if the piston of the second cylinder 32 is pushed out, it is also difficult to push the rear lifting arm 25. At this time, the first motor 35 and the second motor can be started earlier. The second motor 40 rotates the front end of the rear elevating arm 25 through the engagement of the first gear 39 and the first internal tooth 37, so that the rear elevating arm 25 has a certain inclination angle, and through the engagement of the second gear 44 and the second internal tooth 42 The rear end of the main arm 24 is rotated so that the main arm 24 has a certain inclination angle, so that the first cylinder 30 is inclined to a certain degree. When the inclination angle already exists, the first cylinder 30 can easily move The front lifting arm 23 and the second cylinder 32 can easily jack the rear lifting arm 25 .

After the height adjustment of the right bed board 8 is completed, the front stopper 7 can be made close to the front end of the right bed board 8, the rear stopper 6 can be made close to the rear end of the right bed board 8, and then the elastic force of the first spring 14 of the stopper can be utilized. The block 19 is stuck in the draw-in groove 17 to realize the fixing between the right bed board 8 and the front stop board 7 and the rear stop board 6, and complete the merging between the left bed board 2 and the right bed board 8, so that the bed board lying on the right The patient on the bed board 34 directly lies on the nursing bed, and in actual use, the height of the right bed board 8 can be adjusted at any time according to the needs of the environment. It can be adjusted to a height close to the ground, and the patient can be transferred to the right bed board 8 with just a slight lift, which is convenient for rescue work. When the patient undergoes surgery or CT detection, it can The height of the right bed board is adjusted to improve the convenience of transferring patients, and at the same time, the movement range of transferring patients is minimized to avoid discomfort to patients.

Before the right bed board 8 and the left bed board 2 are merged, the baffle plate 55 erected on the left side of the right bed board 8 needs to be put down. At this moment, the sliding cover 68 can be moved horizontally to remove the restriction of the sliding block 70 on the positioning plate 57, and then The positioning plate 57 is pulled upwards through the lifting hole 65, and the locking portion at the lower end of the positioning plate 57 is disengaged from the locking groove 58, so that the separation between the baffle plate 55 and the left side of the right bed board 8 can be completed. If you need to release the fixed state after being fixed, you need to complete two steps of action at the same time, thereby effectively avoiding the situation that someone accidentally pulls the positioning plate 57 and causes the baffle 55 to be put down by mistake, and improves the protection and safety of the baffle 55. During the step-by-step release action, the thumb can be pressed on the upper surface of the sliding cover 68, and the other four fingers can be buckled on the inner wall on the upper side of the lifting hole 65. First, the thumb is used to push the sliding cover 68. At this time, the sliding cover 68 Moving along the track of the upper edge of the baffle 55 toward the center of the baffle 55, the third spring 73 between the sliding block 70 and the bottom of the embedded hole 72 is compressed and becomes elastic. When the sliding block 70 moves to the gap of the stopper 61 When the position is 71, the sliding block 70 can no longer restrict the upward movement of the positioning plate 57 through the limiting portion 61. At this time, the positioning plate 57 can be pulled upwards, and the positioning plate 57 will drive the locking portion 60 to move upwards and break away from the locking groove 58. The second spring between the limiting step 59 and the locking portion 60 is compressed.

In order to ensure the stability when the left bed board 2 and the right bed board 8 are merged into a nursing bed, not only the right bed board 8 is fixed by the limit device, but also the locking between the telescopic arm 84 and the clamping hole 83 is used to further improve the left bed board. 2. Stability when fixing with the right bed board 8, when it is necessary to separate the left bed board 2 from the right bed board 8, in addition to removing the restriction of the limit device, the restriction of the telescopic arm 84 will be removed at the same time. When the restriction of the telescopic arm 84 is removed, you can Directly hold the right telescopic arm 84 exposed to the outside world between the telescopic hole 82 and the fixing hole 86, then push the right telescopic arm 84 to move towards the middle of the right bed board 8, and the left telescopic arm 84 is now Driven by the push arm 77, it will approach the middle of the right bed board 8 at the same time, and break away from the clamping hole 83. When the left telescopic arm 84 leaves the clamping hole 83, the left bed board 2 and the right bed board 8 are no longer fixedly connected to each other. , become an independent entity.

When the left bed board 2 is separated from the right bed board 8, the left bed board 2 can be moved by the roller 87, and the right bed board 8 can be moved by the front pulley 26 and the rear pulley 27, both of which can be used as independent individuals. When the nursing bed can be divided into two beds, more beds can be added in the effective space, more patients can be accommodated, the shortage of hospital beds can be avoided, and temporary emergency medical treatment can be faced more calmly. The expansion bed board 93 can effectively increase the area that the left bed board 2 can lie on for the patient, and avoid the situation that the lying area is too small to cause the patient's discomfort. The cooperation between the screw holes 92 realizes the descending of the expanded bed board 93. When the expanded bed board 93 is located below the left bed board 2, the expanded bed board 93 can be pushed to the left, and the expanded bed board 93 will move leftward along the track of the hidden groove 89 at this time. , finally hidden under the left bed board 2, when the expansion bed board 93 is needed, the expansion bed board 93 can be pulled out again, and the height of the expansion bed board 93 is raised to be consistent with the left bed board 2 by using the lifting screw 95.

In summary, it can be seen that the present invention can be separated. When the patient needs to move, the right bed board 8 of the nursing bed can be directly separated to form a separate transfer trolley, which is convenient for the patient to move. After the car enters the ward, the transfer trolley can be directly combined with the left bed board 2 of the nursing bed to form a complete nursing bed. No matter whether the patient leaves the nursing bed or lies on the nursing bed, there is no need for others to help move it. To a certain extent, it avoids the situation that other people's moving aggravates the patient's discomfort, and the whole process can be easily completed by one person without the need for too much manpower, which saves manpower to the greatest extent.

The center of the bottom of the telescopic blind hole 10 is provided with a limit column 20, and the right end of the first spring 14 is placed outside the limit column 20.
