And, arc recess 27 has been seted up at the middle part of backup pad 3 upper surface, and arc recess 27's inside wall adhesive connection has a rubber pad 28, offering of arc recess 27 is used for preventing patient's chin, the comfort level of patient's chin can be improved in setting up of rubber pad 28, the equal fixedly connected with link 29 in both ends of backup pad 3, the equal fixedly connected with second direction lantern ring 30 in both ends of link 29, and second direction lantern ring 30 cup joints with the activity of guide post 2, consequently backup pad 3 only can follow the vertical upper and lower slip of axial direction of guide post 2.
Moreover, double-head screw sleeves 31 are respectively arranged above the two ends of the supporting plate 3, inner cavities at the upper and lower ends of the double-head screw sleeves 31 are respectively provided with internal threads with opposite rotation directions, the inner cavities at the upper and lower ends of the double-head screw sleeves 31 are respectively movably inserted with a first screw 32 and a second screw 33 through threads, the screw thread turning directions of the first screw rod 32 and the second screw rod 33 are opposite, the upper end of the first screw rod 32 and the lower end of the second screw rod 33 are respectively and fixedly connected with the screw thread lantern ring 19 and the supporting plate 3, the middle part of the outer side wall of the double-head screw sleeve 31 is fixedly sleeved with a handle sleeve 34, therefore, the handle sleeve 34 and the double-head screw sleeve 31 can be rotated to drive the first screw rod 32 and the second screw rod 33 to move up and down in the vertical direction, and the moving directions of the first screw rod 32 and the second screw rod 33 are opposite, so that the vertical distance between the supporting plate 3 and the positioning assembly 4 can be adjusted, and patients with different facial shapes and lengths can be accommodated.
Secondly, inspection through-hole 35 has all been seted up at the positive both ends of eye protection casing 5, and inspection through-hole 35 sets up to the ellipse to different distances between the two eyes of adaptation different patients, the equal fixedly connected with hollow cover 36 of both ends face of eye protection casing 5, the inner chamber activity of hollow cover 36 is pegged graft and is had picture peg 37, the one end and the connecting block 61 fixed connection of picture peg 37, therefore eye protection casing 5 can slide relatively in the horizontal direction with picture peg 37.
Specifically, a limiting plate 38 is fixedly connected to the other end of the inserting plate 37, the limiting plate 38 is located in an inner cavity of the hollow sleeve 36 and is matched with the hollow sleeve 36, the limiting plate 38 is arranged to prevent the inserting plate 37 from being separated from the hollow sleeve 36, the first magnet 39 is fixedly embedded in each of the two end faces of the eye protection cover 5, the second magnet 40 is fixedly embedded in one side face of the limiting plate 38, and the first magnet 39 and the second magnet 40 repel each other, so that when the pressing plate 6 moves in the horizontal direction, the limiting plate 38 can slide in the inner cavity of the hollow sleeve 36, and because the first magnet 39 and the second magnet 40 repel each other, no matter where the pressing plate 6 moves, the eye protection cover 5 can always keep in the middle between the two pressing plates 6, and accordingly the eyes of the patient can be aligned to the two inspection through holes 35 exactly.
Further, at the middle part fixedly connected with pneumatic cylinder 41 of link 29, and the lower extreme of pneumatic cylinder 41 is connected with the last fixed surface of base 1, the last fixed surface of base 1 middle part fixedly connected with guard box 42, and the inner chamber of guard box 42 is provided with hydraulic tank, two pneumatic cylinders 41 all communicate with hydraulic tank through hydraulic oil pipe, the upper surface of guard box 42 is provided with control panel 43, and control panel 43 is used for controlling the flexible of pneumatic cylinder 41, the patient can control the flexible of pneumatic cylinder 41 through control panel 43, and then can adjust the high position of backup pad 3, ensure that patient's chin can be put just in the arc recess 27 at backup pad 3 middle part.
The working principle of the invention is as follows:
when the device is used, a patient firstly controls the stretching of the hydraulic cylinder 41 through the control panel 43 to adjust the height position of the support plate 3, then places the chin in the arc-shaped groove 27 in the middle of the support plate 3, then twists the handle sleeve 34 and drives the double-head screw sleeve 31 to rotate, the first screw rod 32 and the second screw rod 33 both move in the vertical direction through the threaded connection with the double-head screw sleeve 31, and the moving directions of the first screw rod 32 and the second screw rod 33 are opposite, so that the height distance between the support plate 3 and the positioning component 4 can be adjusted until the eye protection cover 5 is just in front of the eyes of the patient;
then, the patient fits the eyes with the front of the eye protection cover 5, and then drives the threaded column 20 to rotate by screwing the knob 24, at the moment, the two second connecting plates 14 are close to each other and drive the two pressing plates 6 to be close to each other, when the two spongy cushions 10 are respectively fitted on the two sides of the head of the patient, the knob 24 is continuously screwed, at the moment, the pressing plates 6 and the first connecting plate 12 do not move any more, but the second connecting plates 14 continue to move and can compress the pressing springs 16, the pressing springs 16 provide thrust to ensure that the spongy cushions 10 cling to the head of the patient, and the head of the patient can be prevented from being injured due to over-large pressure;
after the patient accomplished the inspection, only need with the direct rearward movement of head, then drive arc slider 8 through frictional force and slide at the inner chamber of arc spout 7, because pressure strip 6 sets up to the arc, when consequently arc slider 8 slided, the distance between two arc sliders 8 can increase gradually, until foam-rubber cushion 10 no longer laminates the patient head, the patient can remove the head away.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
