[0030] Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings:

[0032] First embodiment:

[0033] Please see Figure 1 , Figure 2 As shown, a coil device for magnetic resonance cervical imaging includes a housing 1 and a cervical spine tilt adjustment mechanism 2.

[0034] The outer shell 1 includes an upper shell 11, a lower shell 12, and a button unlocking mechanism 13. The upper shell 11 includes an integrally formed arched part 111 and fastening parts 112 located on both sides of the arched part 111. The fastening parts 112 are provided with several pins at the contact position with the lower shell 12. The bottom surface of the fastening parts 112 is provided with a protrusion 113. The protrusion 113 is a hollow cavity. The top surface and the lower inner side of the hollow cavity are respectively provided with a button mounting hole 1131 and a locking hole 1132. The inner wall of the hollow cavity is symmetrically recessed with grooves on the left and right sides. The lower part of the inner wall on the outer side is also provided with a limiting post.

[0035] The button unlocking mechanism 13 includes a button 131 and a locking block 132. The button 131 includes an integrally formed button fixing seat, a button located above the button fixing seat, and an irregularly shaped block located below the button fixing seat with a beveled edge on its outer edge. The locking block 132 includes an integrally formed locking block and sliding pillars located on both sides of the locking block. The locking block is also provided with a limiting block. The button unlocking mechanism 13 is installed in the hollow cavity.

[0036] The lower shell 12 includes an integrally formed snap-fit ​​part 121 and a support part 122. The support part 122 is designed to fit the streamlined shape of the human head, neck and shoulders. The cervical spine tilt adjustment mechanism 2 is installed on the support part 122 at the head and neck position.

[0037] The symmetrically upward protruding parts on both sides of the bearing part 122 are the snap-fit ​​parts 121. The snap-fit ​​parts 121 are recessed with grooves 1211 that match the protrusions of the fastening parts 112. The inner side of the grooves 1211 is also recessed with fastening slots 1212.

[0038] When the button unlocking mechanism 13 is in the locked state, the button 131 passes through the button mounting hole 1131 above the hollow cavity, and the locking block 132 passes through the locking hole 1132 and enters the latching groove 1221 under the action of the spring force. The sliding column cooperates with the sliding grooves on the left and right sides of the hollow cavity.

[0039] When the button unlocking mechanism 13 performs the unlocking step, the button is pressed, and the locking block 132 moves outward along the inclined side of the irregular block against the spring force. The locking block 132 leaves the latch groove 1221 and retracts into the hollow cavity until the limiting block abuts against the limiting seat, and the retraction stops, thus completing the unlocking step.

[0040] The upper shell 11 and the lower shell 12 are assembled by the cooperation of the protrusion 113 and the groove 1211, and the upper shell 11 and the lower shell 12 are locked or unlocked by the button unlocking mechanism 13.

[0041] Please see Figure 2 , Figure 6 , Figure 7 As shown, the supporting part 122 of the lower shell 12 is provided with a slot 1221 at the head and neck position. The lower shell 12 is provided with a through hole 1222 on the rear side. The lower shell 12 also includes a lower cover. After the cervical spine tilt adjustment mechanism 2 is inserted into the slot 1221 from bottom to top and fixed with bolts, the lower cover is fixed to the bottom surface of the supporting part 122 by bolts. The cervical spine tilt adjustment mechanism 2 includes a base 21, a linear motion mechanism 22, a linkage mechanism 23 and a head supporting mechanism 24.

[0042] The top surface of the base 21 is provided with a screw mounting groove that penetrates the top surface of the base along the central axis. One end of the base 21 is provided with a sliding groove 211, and the other end is provided with a first pivot block 212 symmetrically protruding on both sides of the screw mounting groove.

[0043] The linear motion mechanism 22 includes a sliding block 221 and a linear motion component 222 that cooperates with the sliding block 221. The sliding block 221 has a threaded hole 2211 through its center. The upper part of the two sides of the sliding block 221 is symmetrically provided with second pivot blocks 2212, and the lower part of the two sides is symmetrically provided with shafts. The shafts are fitted with sliding bushings 2213. The sliding block 221 is placed in the sliding groove 211 and slides in the sliding groove 211 under the action of the linear motion component 222 and the sliding bushing 2213.

[0044] The linear motion assembly 222 includes a screw 2221 and a spline knob 2222 provided at the end of the screw 2221. The screw 2221 passes through the threaded hole 2211 and is then placed in the screw mounting groove of the base 21. The screw 2221 passes through the through hole 1222 on the rear side of the lower shell 12 and is then fixed to the spline knob 2222 with screws.

[0045] The linear motion component 222 can also be a cylinder, wherein the piston rod and sliding block of the cylinder
