[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Please see Figure 1-4 The present invention provides the following technical solution: a highly applicable lumbar spine dynamic position radiography auxiliary device, comprising a housing 1, a support platform 4 at the upper end of the housing 1, a buffer pad 7 on the side of the support platform 4, an auxiliary body 5 at the upper end of the support platform 4, a handrail 6 on the upper side of the support platform 4, a moving mechanism 2 at the lower end of the interior of the housing 1, and a height adjustment mechanism 3 at the upper end of the interior of the housing 1.
[0023] Specifically, the moving mechanism 2 includes a throttle handle 23, a rotating rod 24, a screw 25, a lifting plate 26, a bevel gear 27, a bevel gear 28, and a caster wheel 29. The screw 25 is rotatably connected to the lower end of the housing 1. The bevel gear 27 is mounted on the upper surface of the screw 25. The bevel gear 28 is meshed with the side of the bevel gear 27. The rotating rod 24 is mounted on the side of the bevel gear 28. The throttle handle 23 is mounted at the other end of the rotating rod 24. The lifting plate 26 is threadedly connected to the lower surface of the screw 25. A caster wheel 29 is mounted at the lower corner of the lifting plate 26.
[0024] By adopting the above technical solution, when moving the device, firstly, turn the handle 23. The rotation of the handle 23 drives the rotating rod 24 to rotate. The rotation of the rotating rod 24 drives the bevel gear 28 to rotate. The rotation of the bevel gear 28 drives the bevel gear 27 to rotate. The rotation of the bevel gear 27 drives the screw 25 to rotate. The rotation of the screw 25 drives the lifting plate 26 to descend. The descent of the lifting plate 26 drives the caster 29 to contact the ground, thereby moving the device through the caster 29.
[0025] Specifically, the moving mechanism 2 also includes a slide groove 21 and a slider 22. The slider 22 is provided on the side of the lifting plate 26, and the inner wall of the housing 1 is provided with a slide groove 21 corresponding to the slider 22.
[0026] By adopting the above technical solution, when the lifting plate 26 is raised or lowered, it will drive the slider 22 to slide inside the slide groove 21, thereby improving the stability of the lifting plate 26 during the lifting process.
[0027] Specifically, the connection between the rotating rod 24 and the housing 1 is rotatably connected via a bearing.
[0028] By adopting the above technical solution, the structure can avoid the problem of the rotating rod 24 getting stuck during rotation.
[0029] In this embodiment, when moving the device, firstly, turn the handle 23. Turning the handle 23 causes the rotating rod 24 to rotate, which in turn causes the bevel gear 28 to rotate. The bevel gear 28 then causes the bevel gear 27 to rotate, which in turn causes the screw 25 to rotate. The screw 25 then causes the lifting plate 26 to descend. The descent of the lifting plate 26 causes the caster wheel 29 to contact the ground, allowing the device to be moved. When the lifting plate 26 rises and falls, it causes the slider 22 to slide inside the slide groove 21, thereby improving the stability of the lifting plate 26 during the rising and falling process. When the device is moved to a suitable position, the caster wheel 29 can be retracted into the housing 1 to ensure the stability of the device.
[0030] Example 2
[0031] The difference between this embodiment and Embodiment 1 is that the height adjustment mechanism 3 includes a lifting platform 31, a second screw 34, a fourth bevel gear 35, a third bevel gear 36, a second rotating rod 37, and a second throttle 38. The second screw 34 is rotatably connected to the upper end of the housing 1. The fourth bevel gear 35 is located on the lower surface of the second screw 34. The third bevel gear 36 is meshed with the side of the fourth bevel gear 35. The second rotating rod 37 is located on the side of the third bevel gear 36. The second throttle 38 is located at the other end of the second rotating rod 37. The lifting platform 31 is threadedly connected to the upper surface of the second screw 34.
[0032] By adopting the above technical solution, when adjusting the height of the device, rotating the second throttle 38 rotates the second throttle 38, which in turn drives the second throttle rod 37 to rotate. The second throttle rod 37 then drives the third bevel gear 36 to rotate, which in turn drives the fourth bevel gear 35 to rotate. The fourth bevel gear 35 then drives the second screw 34 to rotate, which in turn drives the lifting platform 31 to rise and fall, thereby enabling the adjustment of the height of the shooting auxiliary device.
[0033] Specifically, the height adjustment mechanism 3 also includes a limiting groove 32 and a limiting block 33. A limiting block 33 is provided on the upper end of the inner wall of the housing 1, and a limiting groove 32 corresponding to the limiting block 33 is provided on the side of the lifting platform 31.
[0034] By adopting the above technical solution, when the lifting platform 31 is raised or lowered, it will drive the limiting block 33 to slide inside the limiting groove 32, thereby improving the stability of the lifting platform 31 during the lifting process.
[0035] In this embodiment, when adjusting the height of the device, the second throttle 38 is rotated, which in turn rotates the second rotating rod 37, which in turn rotates the third bevel gear 36, which in turn rotates the fourth bevel gear 35, which in turn rotates the second screw 34, which in turn moves the lifting platform 31 up and down. This allows for adjustment of the height of the imaging auxiliary device. When the lifting platform 31 moves up and down, it causes the limiting block 33 to slide inside the limiting groove 32, thereby improving the stability of the lifting platform 31 during the lifting process. When the device needs to be used on a patient, the patient faces the auxiliary device, lies prone on the auxiliary body 5 as far as possible, and takes a hyperflexion film, and / or the patient faces away from the auxiliary device, holds the handrails 6 on both sides, and lies supine on the auxiliary body 5 as far as possible, and takes a hyperextension film.
[0036] The working principle and usage process of this utility model are as follows: When moving the device, firstly, turn the handle 23. Turning the handle 23 drives the rotating rod 24 to rotate, which in turn drives the bevel gear 28 to rotate. The bevel gear 28 then drives the bevel gear 27 to rotate, which in turn drives the screw 25 to rotate. The screw 25 then lowers the lifting plate 26. The lowering of the lifting plate 26 causes the caster wheel 29 to contact the ground, allowing the device to be moved. During the lifting process, the slider 22 slides within the groove 21, improving the stability of the lifting plate 26. Once the device is moved to the desired position, the caster wheel 29 can be retracted into the housing 1 to ensure the device's stability. When adjusting the height of the device, turn the second handle 38 to rotate. The rotation of the second handle 38 drives the second rotating rod 37 to rotate, which in turn drives the third bevel gear 36 to rotate. The third bevel gear 36 drives the fourth bevel gear 35 to rotate, which in turn drives the second screw 34 to rotate. The second screw 34 then drives the lifting platform 31 to rise or fall, thereby adjusting the height of the imaging auxiliary device. When the lifting platform 31 rises or falls, it causes the limiting block 33 to slide inside the limiting groove 32, thereby improving the stability of the lifting platform 31 during the rising or falling process. When the device needs to be used on the patient, the patient faces the auxiliary device and lies prone on the auxiliary body 5 to the maximum extent to take a hyperflexion film, and / or the patient faces away from the auxiliary device, holds the handrails 6 on both sides, and lies supine on the auxiliary body 5 to the maximum extent to take a hyperextension film.
