Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to a film viewing device for medical imaging. Background Art

[0002] Medical imaging refers to the technology and process of obtaining images of internal tissues of the human body or a part of the human body in a non-invasive manner for medical treatment or medical research. It includes the following two relatively independent research directions: medical imaging systems and medical image processing. The former refers to the process of image formation, including the study of imaging mechanisms, imaging equipment, imaging system analysis and other issues, while the latter refers to further processing of the acquired images, the purpose of which is either to restore the original unclear image, or to highlight certain feature information in the image, or to classify the image pattern, etc.

[0003] In clinical medicine, when performing radiological examination on patients, radiation is used to project the patient's diseased part directly onto the image film, and then observation and diagnosis are carried out with the help of a medical image observation light box. Existing medical image observation light boxes are generally set on a fixed base. Since the existing image observation light boxes are large and generally do not have a dimming function, each doctor has different requirements for light. For example, older doctors need brighter light, while young doctors do not like the light to be too bright. In addition, the light source cannot be moved. In some locations that need to be carefully examined, the X-ray film can only be moved for examination. Frequent movement of the X-ray film will cause wear on the surface of the X-ray film, which to a certain extent affects the efficiency and effect of the doctor's observation of the patient's image film.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Place the patient's imaging film in the groove of the transparent plate, and fix the imaging film on the transparent plate through the cooperation between the groove, the imaging film, and the clamping plate to prevent the imaging film from falling off the light box, which will affect the efficiency and effect of subsequent doctors observing the patient's imaging film; then, through the cooperation between the light box, the slider, and the support rod, return the light source on the light box to its initial position, and then turn on the light source so that the light illuminates the imaging film, which is convenient for doctors to observe the patient's imaging film as a whole and make a preliminary diagnosis of the patient's condition; in addition, sliding the support rod on the slider can change the distance between the light source and the imaging film, so that the brightness of the light source meets the needs of different doctors, further improving the efficiency and effect of doctors observing the patient's imaging film;

[0018] 2. When the doctor finds that there is a problem with a certain part of the patient's image film, the position of the light source is changed by the cooperation between the horizontal groove, the slider and the support rod, so that the light source partially illuminates a certain part of the image film, thereby improving the efficiency and effect of the doctor observing the patient's image film; in addition, the first limit block contacts the first limit groove, and the resistance generated after the contact will limit the sliding of the slider on the light box. At the same time, the contact between the ball and the groove will limit the sliding of the support rod on the slider, thereby preventing the external force from accidentally driving the light source to move and affecting the doctor's observation of the image film, thereby further improving the efficiency and effect of the doctor observing the patient's image film;

[0019] 3. When the slider is slid in the horizontal groove and the horizontal position of the light source is adjusted, the first inclined surface, the first limiting groove, the first limiting block and the first spring cooperate to make the slider slide smoothly in the horizontal groove and push the slider to the designated position. Then, the support rod is slid on the slider and the longitudinal position of the light source is adjusted. When the slider is slid in the horizontal groove and the longitudinal position of the light source is adjusted, the support rod is slid smoothly on the slider and push the slider to the designated position through the cooperation among the ball bearing, the groove, the slider and the second spring, thereby changing the position of the light source so that the light source partially illuminates a certain part of the image film, thereby improving the efficiency and effect of doctors observing the patient's image film.

[0020] After the position of the light source is adjusted, the first limit block is restricted from moving inward by the cooperation among the slider, the first screw, the first conical surface, the first convex block and the second inclined surface, and the slider is restricted from sliding in the transverse groove by the resistance generated by the first inclined surface contacting the first limit groove; at the same time, the slider, the second screw and the ball are restricted from moving inward by the cooperation among the slider, the second screw and the ball, and the slider is restricted from sliding in the transverse groove by the resistance generated by the ball contacting the groove, so as to avoid the external force from driving the light source to move unintentionally and affecting the doctor's observation of the image film, thereby further improving the efficiency and effect of the doctor's observation of the patient's image film;

[0021] 4. When the push block is slid on the leg, the first locking block can smoothly pass through the third limiting block through the cooperation among the first locking block, the third limiting block, the third inclined surface, the leg and the fourth spring. At the same time, the two second limiting blocks are driven to move inward at the same time through the cooperation among the push block, the wedge block, the second limiting block and the wedge groove, thereby releasing the restriction on the leg sliding on the base; when the first locking block passes through the third limiting block, the force applied to the push block is canceled, and the third limiting block is reset under the action of the fourth spring rebound force, so that the first plane provided at the end of the third limiting block contacts the first locking block, which limits the push block from moving in the opposite direction toward the outside, thereby eliminating the need to press the push block all the time to release the restriction on the leg sliding in the vertical groove by the second limiting block, thereby improving the efficiency of adjusting the height of the light box; then slide the leg in the vertical groove to adjust the height of the light box, so as to facilitate the needs of doctors of different heights to observe the patient's imaging film, thereby improving the effect of doctors observing the patient's imaging film;

[0022] 5. After adjusting the height of the light box, the third limit block will be driven to move toward both sides again through the cooperation among the push block, the second locking block, the first locking block, the fifth spring, the second plane and the third inclined surface, until the first locking block can pass through the third limit block smoothly, and then the push block is pulled outward so that the first locking block passes through the third limit block before the third limit block is reset, so as to realize the reset of the push block, release the restriction of the second limit block, and drive the second limit block to reset under the action of the rebound force of the third spring, so that it enters the corresponding second limit groove, and the resistance generated by the contact between the second limit block and the second limit groove will limit the support leg from sliding in the vertical groove, and at the same time, after the push block is reset, the baffle plate provided at the end of the push block will be re-positioned between the two second limit blocks, and the resistance generated by the release of the second limit block and the baffle plate will further prevent the external force from accidentally driving the light box to move, affecting the doctor's observation of the imaging film, and further improving the efficiency and effect of the doctor's observation of the patient's imaging film;

[0023] 6. When the inclination angle of the light box needs to be adjusted, the driving wheel is driven to rotate on the leg by toggling the rocker, so that the arc surface provided on the upper side of the driving wheel slides out of the arc groove, and the restriction on the rotation of the driven wheel on the leg is released. Then, the driving wheel, the toggle block, the toggle groove and the rotating shaft are used to drive the light box to rotate a certain angle on the leg. After the angle of the light box is rotated once, the cooperation between the driving wheel, the arc surface and the arc groove will again restrict the rotation of the driven wheel on the leg, thereby restricting the rotation of the light box on the leg, so as to avoid the external force accidentally driving the light box to rotate after the angle of the light box is adjusted, which affects the doctor's observation of the image film, and further improves the efficiency and effect of the doctor's observation of the patient's image film; repeat the above actions many times to adjust the light box to the required angle, so as to meet the needs of different doctors for the inclination angle of the light box, and further improve the efficiency and effect of the doctor's observation of the patient's image film.

[0038] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0039] The present invention provides a medical imaging device for viewing films. Figure 1-Figure 5 As shown, it includes a light box 2 arranged on a bottom frame, a transparent plate 3 is arranged on one side of the light box 2, a groove 4 is arranged on the transparent plate 3, and clamps 5 are arranged on both sides of the groove 4. The patient's image film is placed in the groove 4 of the transparent plate 3, and the image film is positioned on the transparent plate 3 through the contact between the groove 4 and the image film, so that it is convenient for the subsequent light box 2 to illuminate it, thereby improving the efficiency and effect of the doctor observing the patient's image film; at the same time, the clamp 5 is in contact with the image film to clamp the image film on the transparent plate 3, so as to prevent the image film from falling off the light box 2, which affects the efficiency and effect of the subsequent doctor observing the patient's image film;

[0040] A transverse groove 6 is provided on the other side of the light box 2, a slider 7 is slidably connected in the transverse groove 6, a support rod 8 is slidably connected on the slider 7, and a light source 9 is provided at the end of the support rod 8. By moving the slider 7 and the support rod 8 on the light box 2, the light source 9 on the light box 2 is returned to the initial position, and then the light source 9 is turned on so that the light illuminates the image film, which is convenient for the doctor to observe the patient's image film as a whole and make a preliminary diagnosis of the patient's condition; in addition, by sliding the support rod 8 on the slider 7, the distance between the light source 9 and the image film can be changed, so that the brightness of the light source 9 meets the needs of different doctors, further improving the efficiency and effect of the doctor's observation of the patient's image film; and when the doctor finds that there is a problem with a certain part of the patient's image film, by sliding the slider 7 in the transverse groove 6 and sliding the support rod 8 on the slider 7, the position of the light source 9 can be changed, so that the light source 9 partially illuminates a certain part of the image film, thereby improving the efficiency and effect of the doctor's observation of the patient's image film;

[0041] A plurality of first limiting grooves 10 are respectively provided on both sides of the transverse groove 6, and the slider 7 is symmetrically slidably connected with a first limiting block 11 in contact with the first limiting groove 10, and the support rod 8 is provided with a plurality of grooves 12, and the slider 7 is slidably connected with a ball 13 in contact with the groove 12. The first limiting block 11 contacts the first limiting groove 10, and the resistance generated after the contact will limit the slider 7 from sliding on the light box 2. At the same time, the ball 13 contacts the groove 12 to limit the support rod 8 from sliding on the slider 7, thereby preventing external force from accidentally driving the light source 9 to move, affecting the doctor's observation of the image film, and further improving the efficiency and effect of the doctor's observation of the patient's image film.

[0042] Preferably, Figure 4and Figure 5 As shown, first inclined surfaces 14 contacting the first limiting groove 10 are respectively provided on both sides of the first limiting block 11, and a first spring 15 is provided between the first limiting block 11 and the slider 7. The first inclined surface 14 contacts the first limiting groove 10, and the component force generated after the contact will drive the first limiting block 11 to move inward, compressing the first spring 15 provided between the first limiting block 11 and the slider 7, so that the slider 7 slides smoothly in the transverse groove 6 until the first limiting block 11 moves to the next first limiting groove 10, and under the action of the rebound force of the first spring 15, the first limiting block 11 is pushed into the next first limiting groove 10, and the above action is repeated to push the slider 7 to the specified position, thereby changing the position of the light source 9, so that the light source 9 locally illuminates a certain place of the image film, thereby improving the efficiency and effect of the doctor observing the patient's image film.

[0043] Preferably, Figure 4 and Figure 5 As shown, a first projection 16 is provided at the end of the first limit block 11, and a second inclined surface 17 is provided at the end of the first projection 16. A first screw rod 18 is threadedly connected to the slider 7, and a first conical surface 19 is provided at the end of the first screw rod 18 to contact the second inclined surface 17. By tightening the first screw rod 18 on the slider 7, it is driven to move on the slider 7 until the first conical surface 19 provided at the end of the first screw rod 18 contacts the second inclined surface 17 on the first projection 16. The force generated after the contact will limit the first limit block 11 from moving inward. At the same time, the resistance generated by the contact between the first inclined surface 14 and the first limit groove 10 will limit the sliding of the slider 7 in the transverse groove 6, thereby preventing the external force from accidentally driving the light source 9 to move, affecting the doctor's observation of the image film, and further improving the efficiency and effect of the doctor's observation of the patient's image film.

[0044] Preferably, Figure 4As shown, a second spring 20 is provided between the ball 13 and the slider 7, and a second screw 21 is threadedly connected to the slider 7. The end of the second screw 21 contacts the ball 13, and the ball 13 contacts the groove 12. The component force generated after the contact will drive the ball 13 to move inward and compress the second spring 20 provided between the ball 13 and the slider 7, so that the support rod 8 slides smoothly on the slider 7 until the ball 13 moves to the next groove 12, and under the action of the rebound force of the second spring 20, the ball 13 is pushed into the next groove 12, and the above action is repeated to push the slider 7. The second screw 21 is tightened on the slider 7 so that the end of the second screw 21 contacts the ball 13. The force generated after the contact will limit the movement of the ball 13 inward. At the same time, the resistance generated by the contact between the ball 13 and the groove 12 will limit the sliding of the slider 7 in the transverse groove 6, so as to avoid the external force from accidentally driving the light source 9 to move and affecting the doctor's observation of the image film, thereby further improving the doctor's efficiency and effect in observing the patient's image film.

[0045] Preferably, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a vertical slot 22 is provided on the base frame 1, and legs 23 slidably connected to the vertical slot 22 are provided on both sides of the light box 2. By sliding the legs 23 in the vertical slot 22, the height of the light box 2 can be adjusted, which is convenient for doctors of different heights to observe the patient's imaging film, thereby improving the effect of doctors observing the patient's imaging film; a plurality of second limiting slots 24 are respectively provided on both sides of the vertical slot 22, and second limiting blocks 25 are slidably connected to the legs 23, and the upper and lower sides of the second limiting blocks 25 are respectively in contact with the second limiting slots 24, and the resistance generated by the contact between the second limiting blocks 25 and the second limiting slots 24 will limit the legs 23 from sliding in the vertical slots 22, thereby preventing external forces from accidentally driving the light box 2 to move, affecting the doctor's observation of the patient's imaging film, and further improving the efficiency and effect of the doctor's observation of the patient's imaging film.

[0046] Preferably, Figure 6 and Figure 8As shown, a wedge-shaped groove 26 is provided on the second limit block 25, and a push block 27 is provided on the leg 23. A wedge-shaped block 28 is symmetrically provided at the end of the push block 27. A fourth inclined surface 29 in contact with the wedge-shaped groove 26 is provided on one side of the wedge block 28. A third spring 30 is provided between the second limit block 25 and the leg 23. By sliding the push block 27 on the leg 23, the wedge-shaped block 28 provided on the end thereof moves together until the wedge block 28 contacts the wedge-shaped groove 26 on the second limit block 25. The force generated after the two contact will drive the two second limit blocks 25 to move inward at the same time, thereby releasing the restriction on the sliding of the leg 23 on the base, facilitating the subsequent adjustment of the position of the leg 23 in the vertical groove 22, and improving the efficiency of adjusting the height of the light box 2.

[0047] Preferably, Figure 6 and Figure 8 As shown, the push block 27 is provided with a first locking block 31, and the support leg 23 is symmetrically slidably connected with a third limiting block 32, and the two sides of the third limiting block 32 are respectively provided with a first plane 33 and a third inclined surface 34 that are in contact with the first locking block 31, and a fourth spring 35 is provided between the third limiting block 32 and the support leg 23. When the push block 27 is pressed downward, the first locking block 31 will also be driven to move downward, so that the first locking block 31 will contact the third inclined surface 34 provided on one side of the third limiting block 32, and the force generated after the contact will drive the third limiting block 32 to move inward, and compress the third limiting block 32 and the support leg 23. The fourth spring 35 between them allows the first locking block 31 to pass through the third limit block 32 smoothly. When the restriction on the sliding of the leg 23 on the base is released, the first locking block 31 passes through the third limit block 32, and then the force applied to the push block 27 is cancelled. The third limit block 32 is reset under the action of the rebound force of the fourth spring 35, so that the first plane 33 provided at the end of the third limit block 32 contacts the first locking block 31, and the push block 27 is restricted from moving in the opposite direction to the outside. Therefore, there is no need to press the push block 27 continuously to release the restriction of the second limit block 25 on the sliding of the leg 23 in the vertical groove 22, thereby improving the efficiency of adjusting the height of the light box 2.

[0048] Preferably, Figure 6 and Figure 8As shown, a second locking block 36 is slidably connected to the first locking block 31, and second planes 37 contacting the third inclined surface 34 are respectively provided on both sides of the second locking block 36, and a fifth spring 38 is provided between the second locking block 36 and the first locking block 31. By pressing the second locking block 36 on the push block 27, the second locking block 36 moves on the first locking block 31 and compresses the fifth spring 38 between the first locking block 31 and the second locking block 36 until the second plane 37 provided on the second locking block 36 contacts the third inclined surface 34 provided on the third limiting block 32, driving the third limiting block 32 to move toward both sides until the first locking block 31 can smoothly pass through the third limiting block 32, and then pulling the push block 27 toward the outside, so that the first locking block 31 passes through the third limiting block 32 before the third limiting block 32 is reset, thereby realizing the reset of the push block 27 and releasing the restriction of the second limiting block 25; the outer diameter of the second locking block 36 is larger than the outer diameter of the first locking block 31, so that the first locking block 31 can smoothly slide out of the third limiting block 32.

[0049] Preferably, Figure 6 As shown, a baffle 39 is provided at the end of the push block 27, which contacts the ends of the two second limit blocks 25, and is used to limit the movement of the third limit block 32 on the leg 23 after the position of the light box 2 is adjusted, so as to prevent the external force from accidentally driving the light box 2 to move, affecting the doctor's observation of the imaging film, and further improving the efficiency and effect of the doctor's observation of the patient's imaging film; the baffle 39 is provided with a through hole 40 for the two second limit blocks 25 to pass through, so as to release the limiting effect on the second limit blocks 25, so that the second limit blocks 25 can slide smoothly on the leg 23, which is convenient for the subsequent adjustment of the position of the leg 23 on the base frame 1, and improves the efficiency of adjusting the height of the light box 2.

[0050] Preferably, Figure 1 and Fig. 9As shown, both sides of the light box 2 are respectively provided with a rotating shaft 41 rotatably connected to the support leg 23, and the end of the rotating shaft 41 is provided with a driven wheel 42, and the driven wheel 42 is provided with a plurality of arc grooves 43, and a shifting groove 44 is provided between two adjacent arc grooves 43. A driving wheel 45 is rotatably connected to the support leg 23, and the upper and lower sides of the driving wheel 45 are respectively provided with an arc surface 46 in contact with the arc groove 43. The arc surface 46 provided on the driving wheel 45 enters the arc groove 43, and the resistance generated after the two contact will limit the rotation of the driven wheel 42 on the support leg 23, thereby limiting the rotation of the light box 2 on the support leg 23, so as to avoid that after the angle of the light box 2 is adjusted, the external force accidentally drives the light box 2 to rotate, affecting the doctor's observation of the imaging film film, further improving the efficiency and effect of doctors observing patient image films; the left and right sides of the driving wheel 45 are respectively provided with a dial block 47 in contact with the dial groove 44, and the dial block 47 provided on the right side of the driving wheel 45 contacts the dial groove 44. The force generated after the contact drives the driven wheel 42 to rotate on the support leg 23, and at the same time, the torque is transmitted through the rotating shaft 41, which will drive the light box 2 to rotate a certain angle on the support leg 23. The above action is repeated multiple times to adjust the light box 2 to the required angle, thereby meeting the requirements of different doctors for the tilt angle of the light box 2, and further improving the efficiency and effect of doctors observing patient image films; one of the dial blocks 47 is provided with a rocker 48, which is convenient for medical staff to drive the driving wheel 45 to rotate on the support leg 23.

[0051] Example 1

[0052] The present invention provides a medical imaging device for viewing films. Figure 1-Figure 5 As shown, the patient's image film is placed in the groove 4 of the transparent plate 3, and the image film is positioned on the transparent plate 3 by the contact between the groove 4 and the image film, which is convenient for the subsequent illumination of the light box 2, thereby improving the efficiency and effect of the doctor observing the patient's image film; at the same time, the clamping plate 5 is slid on the light box 2 to make it contact with the image film, and the image film is fixed on the transparent plate 3, so as to prevent the image film from falling off the light box 2, which affects the efficiency and effect of the subsequent doctor observing the patient's image film;

[0053] After fixing the imaging film, the light source 9 on the light box 2 is returned to the initial position by moving the slider 7 and the support rod 8 on the light box 2, and then the light source 9 is turned on so that the light illuminates the imaging film, which is convenient for the doctor to observe the patient's imaging film as a whole and make a preliminary diagnosis of the patient's condition; in addition, by sliding the support rod 8 on the slider 7, the distance between the light source 9 and the imaging film can be changed, so that the brightness of the light source 9 meets the needs of different doctors, further improving the efficiency and effect of doctors observing the patient's imaging film;

[0054] When the doctor finds that there is a problem in a certain part of the patient's image film, the position of the light source 9 can be changed by sliding the slider 7 in the transverse groove 6 and sliding the support rod 8 on the slider 7, so that the light source 9 locally illuminates a certain part of the image film, thereby improving the doctor's efficiency and effect in observing the patient's image film; in addition, the first limit block 11 contacts the first limit groove 10, and the resistance generated after the contact will limit the sliding of the slider 7 on the light box 2. At the same time, the contact between the ball 13 and the groove 12 will limit the sliding of the support rod 8 on the slider 7, thereby preventing external forces from accidentally driving the light source 9 to move, affecting the doctor's observation of the image film, and further improving the doctor's efficiency and effect in observing the patient's image film.

[0055] Example 2

[0056] On the basis of Example 1, Figure 3 , Figure 4 and Figure 5 As shown, when the slider 7 is slid in the transverse groove 6 and the transverse position of the light source 9 is adjusted, the first inclined surface 14 contacts the first limiting groove 10. The component force generated after the contact will drive the first limiting block 11 to move inward, compressing the first spring 15 provided between the first limiting block 11 and the slider 7, so that the slider 7 can slide smoothly in the transverse groove 6 until the first limiting block 11 moves to the next first limiting groove 10, and under the action of the rebound force of the first spring 15, the first limiting block 11 is pushed into the next first limiting groove 10, and the above actions are repeated to push the slider 7 to the specified position, thereby changing the position of the light source 9, so that the light source 9 partially illuminates a certain part of the image film, thereby improving the efficiency and effect of doctors observing the patient's image film;

[0057] Then, the support rod 8 is slid on the slider 7. When the longitudinal position of the light source 9 is adjusted, the ball 13 contacts the groove 12. The component force generated after the contact will drive the ball 13 to move inward, and compress the second spring 20 provided between the ball 13 and the slider 7, so that the support rod 8 can slide smoothly on the slider 7 until the ball 13 moves to the next groove 12, and under the action of the rebound force of the second spring 20, the ball 13 is pushed into the next groove 12. Repeat the above actions to push the slider 7 to the specified position, thereby changing the position of the light source 9, so that the light source 9 partially illuminates a certain part of the image film, thereby improving the efficiency and effect of doctors observing the patient's image film;

[0058] After adjusting the position of the light source 9, the first screw 18 is tightened on the slider 7 to drive it to move on the slider 7 until the first conical surface 19 provided at the end of the first screw 18 contacts the second inclined surface 17 on the first protrusion 16. The force generated after the contact will limit the first limit block 11 from moving inwardly. At the same time, the resistance generated by the contact between the first inclined surface 14 and the first limit groove 10 will limit the sliding of the slider 7 in the transverse groove 6. In addition, the second screw 21 is tightened on the slider 7 so that the end of the second screw 21 contacts the ball 13. The force generated after the contact will limit the movement of the ball 13 inwardly. At the same time, the resistance generated by the contact between the ball 13 and the groove 12 will limit the sliding of the slider 7 in the transverse groove 6, thereby avoiding the external force from accidentally driving the light source 9 to move and affecting the doctor's observation of the image film, thereby further improving the efficiency and effect of the doctor's observation of the patient's image film.

[0059] Example 3

[0060] On the basis of Example 1, Figure 6 , Figure 7 and Figure 8 As shown, when the height of the light box 2 needs to be adjusted, the push block 27 is pressed to drive the baffle 39 provided at the end of the push block 27 to move, so that the through hole 40 provided on the baffle 39 is located between the second limit block 25, thereby releasing the restriction on the second limit block 25, so that the second limit block 25 can slide smoothly on the support leg 23, which is convenient for subsequent adjustment of the position of the support leg 23 on the base frame 1, and the efficiency of adjusting the height of the light box 2 is improved; while the push block 27 moves, it will also drive the first locking block 31 to move downward, so that the first locking block 31 contacts the third inclined surface 34 provided on one side of the third limit block 32, and the force generated after the contact will drive the third limit block 32 to move inward and compress the fourth spring 35 between the third limit block 32 and the support leg 23, so that the first locking block 31 can pass through the third limit block 32 smoothly, and at the same time move together through the wedge block 28 provided at the end of the push block 27. The first locking block 31 is then moved to the left of the second locking block 32. The second locking block 31 is then moved to the right of the third locking block 32. The third locking block 32 is then moved to the right of the third locking block 32. The third locking block 32 is then moved to the right of the third locking block 32. The third locking block 32 is then moved to the right of the third locking block 32. The third locking block 32 is then moved to the right of the third locking block 32. The third locking block 32 is then moved to the right of the third locking block 32. The third locking block 32 is then moved to the right of the third locking block 32.

[0061] After adjusting the height of the light box 2, the second locking block 36 on the push block 27 is pressed to move the second locking block 36 on the first locking block 31, and the fifth spring 38 between the first locking block 31 and the second locking block 36 is compressed until the second plane 37 provided on the second locking block 36 contacts the third inclined surface 34 provided on the third limiting block 32, and the third limiting block 32 is driven to move toward both sides until the first locking block 31 can smoothly pass through the third limiting block 32, and then the push block 27 is pulled outward so that the first locking block 31 passes through the third limiting block 32 before the third limiting block 32 is reset, so as to realize the reset of the push block 27 and release the second limiting block 25, and under the action of the rebound force of the third spring 30, the second limit block 25 is driven to reset and enter the corresponding second limit groove 24. The resistance generated by the contact between the second limit block 25 and the second limit groove 24 will limit the support leg 23 from sliding in the vertical groove 22. At the same time, after the push block 27 is reset, the baffle 39 provided at the end of the push block 27 will be re-positioned between the two second limit blocks 25. The resistance generated by the release of the second limit block 25 and the baffle 39 can further prevent the external force from accidentally driving the light box 2 to move, affecting the doctor's observation of the image film, thereby further improving the efficiency and effect of the doctor's observation of the patient's image film.

[0062] Example 4

[0063] On the basis of Example 3, Figure 1 and Fig. 9 As shown, when the tilt angle of the light box 2 needs to be adjusted, the rocker 48 is used to drive the driving wheel 45 to rotate on the leg 23, so that the arc surface 46 provided on the upper side of the driving wheel 45 slides out of the arc groove 43, and the restriction on the rotation of the driven wheel 42 on the leg 23 is released. Then, the shift block 47 provided on the right side of the driving wheel 45 contacts the shift groove 44. The force generated after the contact drives the driven wheel 42 to rotate on the leg 23. At the same time, the torque is transmitted through the rotating shaft 41, which will drive the light box 2 to rotate on the leg 23 by a certain angle. After the angle of the light box 2 is rotated once, the driving wheel 45 moves downward. The arc surface 46 provided on the side enters into the arc groove 43, and the resistance generated by the contact between the two will limit the rotation of the driven wheel 42 on the support leg 23, and then limit the rotation of the light box 2 on the support leg 23, to avoid the external force accidentally driving the light box 2 to rotate after the angle of the light box 2 is adjusted, affecting the doctor's observation of the image film, further improving the doctor's efficiency and effect in observing the patient's image film; repeat the above actions multiple times to adjust the light box 2 to the required angle, thereby meeting the requirements of different doctors for the tilt angle of the light box 2, and further improving the doctor's efficiency and effect in observing the patient's image film.
