[0033] The adjusting mechanism 9 comprises an adjusting rod 10 fixedly connected with the head frame 6, the tail end of the adjusting rod 10 is inserted into the inside of the abdominal frame 7, the adjusting mechanism 9 further comprises an unlocking rod 11, the unlocking rod 11 penetrates through both ends of the abdominal frame 7 and is rotationally connected with the abdominal frame 7, the both ends of the unlocking rod 11 are fixedly connected with rotating handles 15 respectively, the rotating handles 15 can be conveniently held by the user, the rotating handles 15 can drive the unlocking rod 11 to rotate, when the abdominal frame 7 is installed in the head pad 3, the end of the unlocking rod 11 penetrates through the side wall of the head pad 3, the rotating handle 15 is located at one side of the head pad 3, the unlocking rod 11 is fixedly connected with protrusions 14, the protrusions 14 are V-shaped structures, there are two groups of the protrusions 14, the two groups of the protrusions 14 are located at the sides of the two groups of the locking spring sheets 13 respectively, when the unlocking rod 11 rotates, the protrusions 14 on the unlocking rod 11 rotate synchronously, when the protrusions 14 rotate to a certain position, the protrusions 14 will contact with the locking spring sheets 13, when the unlocking rod 11 continues to rotate, the protrusions 14 will push the locking spring sheets 13 to deform.
[0034] As shown in Figure 2 and Figure 4 the both ends of the adjusting rod 10 are fixedly connected with limiting caps 17 respectively, the side wall of the limiting cap 17 is provided with an avoiding groove 18, the limiting cap 17 is matched with the cross-section structure of the head frame 6 and the abdominal frame 7, by arranging the limiting cap 17, the adjusting rod 10 is fixedly installed in the inside of the head frame 6 through the limiting cap 17, the other group of the limiting cap 17 is slidingly installed in the inside of the abdominal frame 7, the limiting cap 17 is closely matched with the head frame 6 and the abdominal frame 7, the contact area is large, has a certain guiding effect, facilitates the adjusting rod 10 to slide along the inner wall of the abdominal frame 7, and can increase the stability of the device, a plurality of groups of bevel teeth are uniformly arranged on the adjusting rod 10, when the adjusting rod 10 is matched and connected with the head frame 6 and the abdominal frame 7, the bevel teeth on the adjusting rod 10 are directed towards the abdominal frame 7, when the adjusting rod 10 enters the abdominal frame 7, first, the limiting cap 17 enters the port of the abdominal frame 7, the avoiding groove 18 is aligned with the position of the locking spring sheet 13, the limiting cap 17 pushes the locking spring sheet 13 to generate a large deformation in the avoiding groove 18 in the process of entering, until the limiting cap 17 completely passes the locking spring sheet 13.
[0035] the bevel teeth are in contact with the bottom of the locking spring sheet 13, because the inclined surface of the bevel teeth is in contact with the locking spring sheet 13, in the process of continuously advancing of the adjusting rod 10, the bevel teeth continuously push the locking spring sheet 13 to deform and then are embedded between the adjacent two groups of the bevel teeth, the working principle is the same as that of the cable tie, because the inclination direction of the locking spring sheet 13 is the same as that of the bevel teeth, the matching between the adjusting rod 10 and the locking spring sheet 13 has an anti-reverse effect, the adjusting rod 10 moves towards the abdominal frame 7, drives the head frame 6 to move towards the abdominal frame 7 synchronously, the distance between the head frame 6 and the abdominal frame 7 is reduced, because there are a plurality of groups of the bevel gears and they are uniformly distributed, the change of the distance between the head frame 6 and the abdominal frame 7 can be relatively accurate.
[0036] As shown in Figures 2 to 5 The neck support grid plate 8 is embedded in the slot 12 on the same side of the head frame 6 and the abdominal frame 7, respectively, and is made of elastic material. When the distance between the head frame 6 and the abdominal frame 7 is reduced, the two ends of the neck support grid plate 8 are subjected to pressure, and the pressure causes the neck support grid plate 8 to start to change from a flat structure to an arched structure. After the neck support grid plate 8 arches, the middle of the head cushion 3 is lifted, and the middle of the head cushion 3 also forms an arched structure. The arch degree is inversely proportional to the distance between the head frame 6 and the abdominal frame 7. By changing the distance between the head frame 6 and the abdominal frame 7, the arch degree of the neck support grid plate 8 is changed, thereby changing the arch degree of the head cushion 3, so that it adapts to the needs of different patients, and the device can be used by patients with spinal curvature, effectively improving the practicability of the device.
[0037] The working principle of the utility model provides, in use, the patient should put the upper body on the head cushion 3, the waist and hips on the waist cushion 4, and the lower limbs on the leg cushion 5. The head cushion 3 and the leg cushion 5 can be respectively controlled to rotate relative to the waist cushion 4 through the rocking bed, and the body position of the upper body and the lower body of the patient can be respectively adjusted to adapt to the needs of different patients.
[0038] When the patient with kyphosis is nursed in bed, the height of the patient's neck position needs to be adjusted additionally. The top of the head cushion 3 can be pressed to make the top of the head frame 6 move towards the abdominal frame 7, and the head frame 6 drives the adjusting rod 10 to move synchronously. When the adjusting rod 10 moves towards the abdominal frame 7, the limiting cap 17 at one end of the adjusting rod 10 first enters the port of the abdominal frame 7, the avoiding slot 18 is aligned with the position of the locking spring 13, and the limiting cap 17 pushes the locking spring 13 to produce a large deformation in the avoiding slot 18 in the process of entering, until the limiting cap 17 completely passes the locking spring 13, and then the oblique tooth comes into contact with the bottom of the locking spring 13. Since the inclined surface of the oblique tooth contacts the locking spring 13, in the process of the adjusting rod 10 continuing to advance, the oblique tooth continuously pushes the locking spring 13 to deform and embed between the adjacent two groups of oblique teeth. Its working principle is the same as that of a strap. Since the inclination direction of the locking spring 13 is the same as that of the oblique tooth, the cooperation between the adjusting rod 10 and the locking spring 13 has a reverse effect. As the adjusting rod 10 enters the inside of the abdominal frame 7, the distance between the head frame 6 and the abdominal frame 7 is reduced, so that the two ends of the neck support grid plate 8 are subjected to pressure and start to change from a flat structure to an arched structure. After the neck support grid plate 8 arches, the middle of the head cushion 3 is lifted, and the middle of the head cushion 3 also forms an arched structure. The arch degree is inversely proportional to the distance between the head frame 6 and the abdominal frame 7. By changing the distance between the head frame 6 and the abdominal frame 7, the arch degree of the neck support grid plate 8 is changed, thereby changing the arch degree of the head cushion 3, so that it adapts to the needs of different patients.
[0039] The utility model covers any alternative, modification, equivalent method and scheme which is made on the essence and range of the utility model. In order to make the public have the thorough understanding of the utility model, the specific details are explained in the following utility model preferred embodiment, and the utility model can also be completely understood without the description of these details to the person skilled in the art. In addition, in order to avoid unnecessary confusion to the essence of the utility model, the well-known method, process, flow, element and circuit etc. are not explained in detail.
[0040] The above only is the preferred implementation of the utility model, should point out, for the ordinary skill in the art of the present technology, on the premise of not departing from the principle of the utility model, still can make a number of improvement and embellishment, these improvements and embellishment also should be regarded as the protection range of the utility model.
