The inclined plate 8 comprises a second hard plate 81 and a second soft supporting pad 82 contacting with the thigh. In order to ensure the effective contact of the second inclined plate 8 and the bed body, a connecting structure which realizes the rotary connection with the inclined plate 8 is arranged on the thigh side of the first hard plate 21. The connecting structure includes a ring structure 83 having a rotation shaft hole 42 integrally connected to the thigh side of the first hard plate 21, and a first rotation shaft 84 integrally connected to the second hard plate 81 and capable of extending into the rotation shaft hole 42. The ring structures 83 are arranged on two sides of the first hard plate 21, and the rotating shaft penetrates through and is connected with the transverse edge of the whole second hard plate 81. The first soft supporting pad 22 is not connected with the second soft supporting pad 82, but the distance generated by rotation is not large, so that the gap at the connection part cannot cause discomfort to people due to rotation.
Anti-rotation structures for ensuring that the moving block 32 does not rotate along with the threaded rotating rod 31 are arranged on two sides of the moving block 32. The anti-rotation structure comprises two limiting plates 12 which extend out of the base part 1 and are arranged along the transverse direction of the base part 1; the distance between the two limit plates 12 is equal to the width of the two moving blocks 32. By this arrangement, the moving block 32 is just limited between the two limit plates 12. Support holes 611 are formed in the two support blocks 61, and threads are not arranged on the sections of the rotating rods 31 arranged in the two support holes 611 and internally threaded, so that the support rotation resistance can be effectively reduced. And bearing structures are arranged at the positions of the support holes 611, so that the rotation friction at the contact position is reduced to the greatest extent, and the smooth operation is ensured.
The connecting position of the connecting rod 4, the moving block 32 and the lower limb placing part 2 comprises two extending plates 41, the connecting rod 4 is arranged between the extending plates 41, rotating shaft holes 42 are formed in the extending plates 41 and the connecting rod 4, connecting shaft rods 43 are arranged in the rotating shaft holes 42, and the rotating connection is realized through the structure.
The above description of the embodiments is only intended to illustrate the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several modifications can be made to the present invention, and these modifications will fall within the protection scope of the claims of the present invention.
