Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a screen clamping and adjusting device applicable to a synoptophore. Background Art

[0002] A synoptophore is a large optoelectronic ophthalmic synoptophore integrating optics, mechanics and electronics, also known as a large amblyoscope or straboscope, which evolved from the Worth amblyoscope. Its main structure includes two lens barrels that can rotate in various directions around three axes, and can achieve a variety of movements, including horizontal movements in the adduction and abduction directions around the vertical axis, vertical movements in the up and down directions around the horizontal axis, and rotational movements in the inner and outer directions around the sagittal axis.

[0003] The synoptophore can comprehensively evaluate the binocular visual function status of patients, including pupillary light reaction, eye movement coordination, stereoscopic vision, accommodation ability, etc., and provide accurate diagnostic information for doctors; based on the examination results of the synoptophore, doctors can use the synoptophore for visual training to improve visual problems such as amblyopia and strabismus, and improve the visual quality and quality of life of patients.

[0004] Currently, the most commonly used method when using a synoptophore is to manually place pictures with different contents and shapes through the picture device structure (card slot) at the distal end of the synoptophore lens barrel for visual stimulation treatment or examination of patients. However, this method requires doctors to continuously manually replace different pictures, and the replacement process is cumbersome. Moreover, during this period, the eyes of the examinees cannot be continuously stimulated, resulting in poor consistency in the eye movement (especially the eye position) and perceptual state of the examinees. When stimulating, an electronic screen is used to present pictures, and the background computer controls the picture content and replaces the graphics continuously in a slide show manner, which can ensure that the positions of the patient's binocular eyes remain unchanged, and the states during different graphic stimulations are highly consistent. However, when using the screen, there is no corresponding fixing or clamping device for fixing the screen, and there are defects such as difficulty in maintaining the stable position of the screen and difficulty in rotating with the change of the synoptophore angle to a certain extent, resulting in limited use.

[0005] Therefore, a screen clamping and adjusting device applicable to a synoptophore is needed to solve the above technical problems. Summary of the Utility Model

Detailed implementation mode Embodiment 1

[0023] The utility model discloses a screen clamping and adjusting device applicable to a synoptophore, including: a screen placement rack 1 and a clamping device 2; the clamping device 2 is an overall circular ring structure, and the screen placement rack 1 is arranged on the side wall of the clamping device 2;

[0024] The clamping device 2 includes: a clamping seat 21, a pressing ring 22 and a clamping assembly 23; the clamping seat 21 is a circular ring structure, an annular groove is opened on the end surface of the clamping seat 21, pressing grooves 216 are evenly opened on the annular groove, and the clamping assembly 23 is movably installed on the pressing grooves 216. The clamping assembly 23 includes a clamping head 231 and a link rod 232. The link rod 232 is movably installed on the pressing groove 216, and the front end of the link rod 232 is fixedly installed with the clamping head 231; an arc-shaped groove 233 is opened on the end surface of the pressing ring 22 close to the clamping head 231, and the pressing ring 22 is connected to the bottom of the annular groove through a spring 121. The other end of the link rod 232 is clamped in the arc-shaped groove 233; by pressing or relaxing the pressing ring 22, the outward expansion or contraction of the clamping head 231 is controlled to achieve clamping or relaxation; through the clamping device 2, the whole device can be clamped on the synoptophore. At the same time, since the side end of the synoptophore is a circular structure and can be adjusted, accordingly, the clamping is made into a circular form correspondingly, which is convenient for clamping. Specifically, when clamping, press the pressing ring 22. Under the action of pressure, the link rod 232 will move clockwise, and the clamping head 231 will expand outward. Then release the pressing plate. Under the action of the elastic force of the spring 121, the pressing plate will reset, and at the same time, the link rod 232 will also reset. At this time, the clamping head 231 will move inward to clamp the side end of the synoptophore. At the same time, in order to ensure that the above process can be better realized, a torsion spring is arranged at the rotating part of the link rod 232, and the clamping effect is further strengthened by the force of the torsion spring; in addition, the inner surface of the clamping head 231 is covered with rubber material, and the friction with the synoptophore base is increased through the rubber material, and the stability during the fixing time is strengthened, so that it is not easy to rotate. Embodiment 2

[0025] In this embodiment, the relative angle between the connecting rod 232 and the pressing groove 216 is between 10° and 90°. Specifically, considering the time when the connecting rod 232 rotates to drive the clamping head 231, if the relative angle between the connecting rod 232 and the pressing groove 216 is between 0° or 90°, it is in a relatively horizontal or vertical state, and it is impossible to push the connecting rod 232 through the pressing ring 22. Therefore, it is preferably controlled between 0° - 90°. At the same time, through actual use verification, the best angle is between 35° - 45°. At this time, the obtained component force is relatively large and it is easier to rotate.

[0026] In addition, in this embodiment, receiving grooves 211 are symmetrically arranged on the annular groove, and pressing blocks 221 are fixedly arranged on the pressing ring 22 corresponding to the positions of the receiving grooves 211. The pressing blocks 221 facilitate the user to press and use. At the same time, fixing blocks 213 are symmetrically and fixedly arranged on the side wall of the clamping seat 21. The fixing blocks 213 are fixedly installed with telescopic rods 214 along the radial direction of the clamping seat 21. The end of the telescopic rod 214 is movably installed with the screen placement rack 1. The position of the screen placement rack 1 and the synoptophore can be adjusted through the telescopic rod 214. At the same time, the screen placement rack 1 can be rotated and fixed at any position in the horizontal and vertical positions. When fixing, it is fixed by bolts or the damping of the rotating shaft itself. The method of using bolts or the damping rotating shaft is prior art and will not be described in detail here, so that it can be maintained in a better focusing position to ensure clarity during use. The fixing form of the telescopic rod 214 is prior art and will not be described in detail here. A sunken groove 217 is opened inside the clamping seat 21 on the side opposite to the clamping head 231. By providing the sunken groove 217, the part of the black rubber ring on the side of the synoptophore can be adapted, so that the device can be completely inserted into the side end of the synoptophore. In addition, the screen placement rack 1 is of a square structure. The square structure can better adapt to the placement requirements of the screen, such as the screens on mobile phones, tablets, etc. Limiting protrusions 13 are provided at the upper and lower ends of the screen placement rack 1 to limit the screen from falling. A handle 12 is installed in the middle of the upper limiting protrusion 13. A spring 121 is sleeved on the handle 12. The end of the handle 12 extends to the lower end inside the protrusion 13, and a circular hole 11 is opened in the middle of the screen placement rack 1. After pulling the handle 12, the screen is placed in, and then the handle 12 is released. The screen is further clamped and fixed through the handle 12. At the same time, a circular hole 11 or a hollow is opened in the middle of the screen placement rack 1, which can effectively save materials.

[0027] The working principle of the present utility model is as follows: After the preparation work is completed, hold the handheld blocks 212 with both hands respectively, press the pressing block 221 with the thumbs to make the clamping heads 231 open outwards, then align them with the corresponding parts of the synoptophore. After alignment, release the pressing block 221 to fix it. Then pull out the screen placement rack 1 and rotate it to the horizontal position. At this time, place the tablet or mobile phone. When placing, the handle can be pulled. After placing, release the handle to further fix the mobile phone or tablet. Then rotate the screen placement rack 1 back to fix it. Adjust the actual position through the telescopic rod 214 according to actual needs. After the adjustment is completed, it can be started to use. After use, the device can be placed or disassembled in reverse according to the above steps.
