The spline that gear 21 matches, flower key length are greater than the internal diameter of the 4th gear 21, the 4th rotation axis 16 rotation drive the simultaneously
Helical rotation, first gear 17 and the 4th gear 21 only rotate three rotation axis 14 together, and spline can be in first gear 17
With horizontally slip in rotation process in the 4th gear 21, first gear 17 and second gear 18 are identical, 18 concentric zones of second gear
Dynamic third gear 19 rotates one week, and the 4th gear 21 engaged through idle pulley 20 also rotates one week, it is ensured that the 4th rotation axis 16 and the
The circumference of three rotation axis 14 rotation is identical, both sides synchronous interaction；
First movable block 12 and the second movable block 13 are slidably connected in rack 1 respectively, set respectively in third rotation axis 14
There is the first threaded rod 29 being threadedly coupled with the first movable block 12, the second threaded rod 30 being threadedly coupled with rack 1, the second screw thread
The lead of bar 30 is greater than the lead of the first threaded rod 29, and the 4th transmission shaft 16 is respectively equipped with the third connecting with the second movable block 13
The lead of threaded rod 31, the 4th threaded rod 32 being threadedly coupled with rack 1, the 4th threaded rod 32 is greater than leading for third threaded rod 31
Journey, when the 4th 16 rotary motion of rotation axis, third threaded rod 31, the 4th threaded rod 32, the second movable block 13 and rack 1 constitute difference
Dynamic worm drive, the second movable block 13 is identical as the rotation direction of rack 1,16 each rotation of the 4th rotation axis, 13 band of the second movable block
It moves right 3 entirety of clamping plate to move downward, the distance actually moved is the difference of 31 lead of the 4th threaded rod 32 and third threaded rod, together
Reason, when third 14 rotary motion of rotation axis, the first threaded rod 29, the second threaded rod 30, the first movable block 12 and rack 1 constitute difference
Dynamic worm drive, the first movable block 12 is also identical as the rotation direction of rack 1,14 each rotation of third rotation axis, the first movable block 12
Drive left clamp 2 whole to the right, the distance actually moved is the difference of 29 lead of the second threaded rod 30 and the first threaded rod, left clamp
2 and right clamping plate 3 when being drawn close in, it is ensured that stroke relative decrease has the function that fine adjustments, patient is avoided to be pinched, more
Practicability and effectiveness, more human nature cares；
During 24 rotary motion of transmission shaft, the 4th rotation axis 16 under the action of transmission shaft 24, transport to the left by spiral
Dynamic, first gear 17 is connect with 16 spline of the 4th rotation axis, and the axial length of spline is greater than the internal diameter of first gear 17, the first tooth
17 lower ends are taken turns in the groove of rack 1, when the 4th rotation axis 16 moves downward, 17 position of first gear is constant, and spline exists
Sliding in first gear 17, it is ensured that the stability that first gear 17 and second gear 18 engage, and then guarantee the 4th rotation axis 16
It links with third rotation axis 14 steady effective, 24 left end of transmission shaft is slidably connected in keyway, it is ensured that transmission shaft 24 drives the 4th
While rotation axis 16 rotates, and guarantee that the 4th rotation axis 16 can move downward, is successively fixed with clockwork spring on transmission shaft 24
33 and ratchet 34, pawl 35 be fixed in rack 1, due to the effect of click, prevent transmission shaft 24 from reversing, safely and effectively
The head of immobilized patients, one end of clockwork spring 33 and then are constantly tightened with the rotation of transmission shaft 24, clockwork spring 33
The other end is fixed in rack 1, is completely fixed and is finished in patients head, guarantees the also certain rotation space of clockwork spring 33,
Avoid the occurrence of that head is also unlocked good and clockwork spring 33 has rotated stuck phenomenon, in operation or contrast Imaging Procedures, such as
There is unexpected phenomenon in fruit, pushes pawl 35 aside, and 33 release action power of clockwork spring quickly drives transmission shaft 24 to invert, and then controls
Left clamp 2 and right clamping plate 3 are retracted rapidly, ensure that patient can save patient's time quickly and effectively far from hospital bed, can be timely
It is effectively obtained treatment；
After operation, pawl 35 is also pushed aside, clockwork spring 33 drives the reversion of transmission shaft 24 to reset, when patient is far from headrest
Afterwards, block 22 is unclamped, block 22 slides in the first movable block 12 and the second movable block 13 respectively, and catch pawl 23 is made to be detached from left clamp
2 and right clamping plate 3, rotary shaft 27 reversely rotates at this time, and slider pin 25 disengages the first rotation axis 6 and the second rotation axis 7, in torsional spring 28
Under the action of, the first rotation axis 6 and the second rotation axis 7 reset, and under the engagement of rack-and-pinion, left clamp 2 is in the first movable block
Initial position is slid on 12, right clamping plate 3 also slides into initial position on the second movable block 13, then the positive rotation of rotary shaft 27
Turn, lock the first rotation axis 6 and the second rotation axis 7, keeps the stabilization of headrest.
The more traditional device of the present invention has following benefit: 1) head self gravity is utilized, in the first partial gear and the
Under the action of two partial gears, the effect that Primary Location clamps is generated, clever structure, flexibly practical, effect is obvious；2) first
Under the premise of step positioning clamps, using differential screw drive mechanism, subtle adjustment is carried out, avoids the occurrence of because stroke is excessive, causes
Patient injures and is not easy the case where clamping, and can more embody care of the medical staff to patient, be worthy to be popularized；3) using synchronous interaction
Mechanism, left clamp and right clamping plate are simultaneously clamped on and are unclamped, easy to operate, effective and rapid, improve working efficiency；4) ratchet spine is used
The emergency set of pawl protective device and clockwork spring, such as encounters special circumstances, can quickly flick left clamp and right clamping plate, energy
Enough try to gain time precious to one for patient.
Structure of the invention is ingenious, convenient and practical, can effectively clamp incidence, improves working efficiency, and utilize head
Self gravity, automatic preliminary adjusting clamped position, is saved the time, while using linkage mechanism, it is convenient to operate, and the popularization of value has
Very high potential value.
