[0022] The head pad plate 3 is provided with a head placing groove 10, the head placing groove 10 is provided with a transition surface 11 at the end away from the connecting seat 7, the transition surface 11 is smoothly connected with the head placing groove 10, the transition surface 11 extends to the end of the connecting seat 7, and the head placing groove 10 is provided with a fixing piece on both sides.

[0023] The head placing groove 10 is used for placing the head, the head placing groove 10 is communicated with the inside of the neck placing pad 6 through the transition surface 11, and the comfort after the neck and the head are placed can be improved through the smooth transition of the transition surface 11, and the fixing piece is used for fixing the head after the head is placed, so that the head keeps stable in the process of cisternal imaging and the imaging shooting quality is improved.

[0024] Specifically, in the embodiment, the fixing piece comprises a sunken groove 12 arranged on the head pad plate 3, the sunken grooves 12 are symmetrically arranged, the sunken grooves 12 are arranged in a T shape, a cover plate 13 is rotatably connected in the sunken groove 12 close to the top, a rotating seat 14 is fixed to the bottom end of the cover plate 13 away from the sunken groove 12, a horizontal rod 15 is arranged in the rotating seat 14 and fixed between the inner walls of the sunken groove 12, the rotating seat 14 rotates outside the horizontal rod 15, a torsional spring 16 is arranged outside the horizontal rod 15 and fixed between the rotating seat 14 and the inner wall of the sunken groove 12, a gas cylinder 17 is rotatably connected in the sunken groove 12, and a clamping piece 18 is rotatably connected to the output end of the gas cylinder 17.

[0025] The cylinder 17 is rotatably connected to a connecting sleeve shaft 19 away from the output end. A rotating rod 20 is fixed inside the connecting sleeve shaft 19. The rotating rod 20 is rotatably connected inside the head pad plate 3. A silicone pad 21 is fixed inside the clamping piece 18. The clamping piece 18 is arc-shaped. The silicone pad 21 has several through holes 22 on its side. A connecting rod 23 is fixed to the side of the cylinder 17. A sliding block 24 is hinged to the end of the connecting rod 23 away from the cylinder 17. The sliding block 24 slides along the inside of the cover plate 13. The cover plate 13 has a groove 25 for the sliding block 24 to slide.

[0026] In this embodiment, the end of the cylinder 17, which is submerged inside the groove 12, is fixed to the connecting sleeve shaft 19. A rotating rod 20 is fixed inside the connecting sleeve shaft 19. In this embodiment, the end of the rotating rod 20 away from the connecting sleeve shaft 19 is connected to a driving device, such as a motor. This driving device, not shown in the figure, is used to drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, as... Figures 4-6 As shown, after the rotating rod 20 rotates towards the top of the head pad plate 3, it drives the cylinder 17 to rotate. The connecting rod 23 on the side of the cylinder 17 rotates upward at an angle. The connecting rod 23 and the end of the cylinder 17 are fixedly set. Since the overall length of the connecting rod 23 remains unchanged, it starts to rotate between the end away from the cylinder 17 and the sliding block 24, and pushes the sliding block 24 to slide along the inside of the groove 25. As the rotating rod 20 continues to rotate, the angle between the cylinder 17 and the bottom of the sinking groove 12 gradually increases, and the cover plate 13 rotates and opens. At the same time, the rotating seat 14 at the bottom of the cover plate 13 rotates along the axial direction of the cross bar 15, and the torsion spring 16 outside the cross bar 15 tightens.

[0027] When the cylinder 17 is driven to lift, the output of the cylinder 17 controls the extension of the clamping plate 18. Then, the silicone pad 21 on the inner side of the clamping plate 18 contacts the side of the human head, and the cylinder 17 can continue to output to clamp the head. At the same time, the contact between the silicone pad 21 and the head improves the comfort of the head during the clamping process. In addition, multiple through holes 22 are provided on the side of the silicone pad 21 to improve the breathability during the head contact process.

[0028] When storing, the cylinder 17 is retracted again, and the rotating rod 20 is rotated at the same time. The torsion springs 16 at both ends of the rotating seat 14 are automatically released and reset. Combined with the movement of the cylinder 17, the cover plate 13 can be automatically reset to cover the top of the sinking groove 12, thereby reducing space occupation when not in use.

[0029] The distance between the head cushion plate 3 and the fixed frame body 4 is adjustable, and after adjusting the distance between the head cushion plate 3 and the fixed frame body 4 through the driving part, the distance between the head and the body can be adjusted, so as to facilitate the use of different people. Specifically, the driving part includes a jacking cylinder 26 fixed on the side surface of the fixed frame body 4, and the output end of the jacking cylinder 26 is fixed on the bottom of the head cushion plate 3. The jacking cylinder 26 is also driven by the air source, and when jacking, the head cushion plate 3 can be driven to move, and the T-shaped connecting plate 9 at the bottom of the head cushion plate 3 moves along the inside of the sliding groove 8.

[0030] Further in the embodiment, the inside of the neck placement pad 6 is embedded with air bags 27, the air bags 27 are symmetrically arranged, and the two air bags 27 are communicated. One side of one of the air bags 27 is connected with a gas guide pipe 28, the gas guide pipe 28 extends out along the side surface of the neck placement pad 6 away from the air bag 27, and the extending end of the gas guide pipe 28 is connected with a gas valve 29. After placing the neck, the gas guide pipe 28 is connected with the air supply source by opening the gas valve 29, air is introduced into the inside of the air bag 27, so that the air bag 27 is inflated to clamp the neck, improve the fixing effect of the neck, and further improve the stability of the head.

[0031] In the embodiment, the two ends of the bed body base 2 are in an open state, and an arc-shaped soft rubber plate 30 is fixed between the bed body base 2 and the fixed frame body 4. The arc-shaped soft rubber plate 30 is symmetrically arranged, and a plurality of air holes 31 are arranged on the side surface of the fixed frame body 4. The arc-shaped soft rubber plate 30 can cover the gap between the bed body base 2 and the fixed frame body 4, and is used for placing the arms and other parts. At the same time, the two ends of the bed body base 2 are in an open state, and the air holes 31 are arranged on the side surface of the fixed frame body 4, so that the inside and outside of the whole fixed frame body 4 are in a flow communication state.

[0032] The combination block includes a fixed block 32 fixed on the bottom of the bed body base 2, and a pressure bearing block 33 arranged on the end of the fixed block 32 away from the bed body base 2.
