[0028]In the following, embodiments of the present invention will be described below, and those skilled in the art can easily understand other advantages and efficacy of the present invention, apparently, as described in the present invention. , Not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.
[0029]Refer to the instructionsfigure 1 ,23 and 6, a photographic instrument for objective visual census, including a box 1, and a viewing port 2 is opened on both sides of the box 1, and the casing 1 is opened. There is a slot 16, and both sides of the box 1 are provided with a bundle tape 8, and the two bundle belts 8 are connected to the casing 1 via the active hinge activity, and two tests are provided inside the cabinet 1. The cartridge 11 is provided with a rotating mechanism and a mounting mechanism in which the rotating mechanism includes two support cylinder 6, and one end of the two support cartridges 6 is fixedly connected to the corresponding position, respectively. Both of the two of the support cartridges 6 are provided with a first rotating shaft 10, and one end of the two first rotating shafts 10 is fixedly coupled to the test drum 11 of the respective position, and both sides of the box. A hand 7, one end of the two first axis 10 opposite the first handle 7 is fixedly coupled, and the top of the two test drum 11 is provided with a rubber sheet 3, and the two of the rubber sheet 3 is at the top end. All of which is fixedly connected to the horizontal plate 4, and two of the cross plates 4 and the casing 1 are fixedly coupled with two stands 5.
[0030]Further, the inside of the four of the vertical plate 5 is fixedly connected to the second slider 28, and the four of the second sliding rods 28 is movable with a second slider 27, four of the second sliding. On-side of the block 27 is fixedly coupled with a fifth connecting plate 26, which is convenient to drive the spring 29 to compress or elongate.
[0031]Further, both the top of the cross plate 4 are fixedly connected to the third connection plate 24, and the two third connecting plates 24 are fixedly connected to the fourth connecting plate 25, four of the fifth connecting plates 26. One end is fixed to the fourth connecting plate 25 of the respective position, so that the fifth connecting plate 26 is moved.
[0032]Further, four of the second sliding blocks 27 are fixedly coupled with a spring 29, and the bottom end of the four of the spring 29 is fixedly connected to the corresponding position, respectively, and the four spring 29 is movable. At the respective position of the second slider 28, the spring 29 is compressed or elongated, and the vibration is effectively reduced to improve the stability of the test drum 11.
[0033]Further, both ends of the two support cartridges 6 are fixedly coupled with two pulley 9, and both sides of the box 1 are opened on both sides, and the four of the four pulleys 9 are slid in the corresponding position, respectively. Inside the groove 22, the friction is reduced, and it is convenient for the support cartridge 6 to rotate.
[0034]The implementation scenario is concrete: the staff rotates the first handle 7 to drive the first spool 10 to rotate, and the test drum 11 is rotated, the patient observes the correction pattern on the test drum 11, the recording instrument in the box 1 records the patient's eye change And through the computer, no patient is subjectively judging, improve the correctness of the diagnosis result, and the test drum 11 rotates the supporting support hole 6 to rotate, so that the pulley 9 is rotated in the chute 22, improve the stability of the test drum 11 rotation. When the test drum 11 is rotated to contact the rubber sheet 3, thereby driving the transverse plate 4 vibrating, and the third connecting plate 24 vibrates, the third connecting plate 24 vibrates the fourth connecting plate 25 vibration, thereby driving the second slider 27 Move on the second slider 28, which can cause the spring 29 to compress or elongation, effectively reduce the vibration, improve the stability of the test drum 11, by providing two sets of testing drum 11, facilitating observation of the patient's eye change, the implementation The way the way the prior art is mostly subjective, affecting normal detection.
[0035]Refer to the instructionsfigure 1 ,24, 5, and 7, an eye-optic instrument for objective visual census, including a mounting mechanism, the mounting mechanism comprising two extruded plates 15, and the two extruded plates 15 are respectively located. The bottom of the corresponding position is at the bottom, and one side of the two of the extrudate plate 15 is fixedly connected to the first connection plate 14, and the two first connecting plates 14 opposite side are fixed. The second connecting plate 19 is provided with a threaded rod 12 at the bottom of the two second connecting plates 19, and one end of the two threaded rods 12 is connected to the casing 1 through a bearing activity, two threaded rods. 12 The outer peripheral surface is provided with a threaded sleeve 13, and the two threaded sleeves 13 are threaded with the threaded rod 12 of the respective position, and the two second connecting plate 19 is fixed to the respective position of the threaded sleeve 13. connection.
[0036]Further, both the top of the threaded rod 12 is provided with a first slider 20, and one end of the two first sliding rods 20 is fixed to the casing 1, two of the first sliders 20 The outer peripheral surface is provided with a first slider 23, and the top end of the two second connecting plates 19 is fixed to the first slider 23 of the respective position, and the stability of the threaded sleeve 13 is respectively, respectively.
[0037]Further, one end of the two first sliding rods 20 is fixed to the finite position block 18, which limits the movement distance of the first slider 20.
[0038]Further, the outer circumferential surface of the two threaded rods 12 is fixed to the first cone gear 17, and the two first cone gear 17 are provided with a second cone gear 31, two of the second cone gear. 31 is engaged with the first cone 17, respectively, and the two second tapered gear 31 is fixedly coupled to a second axis 30, and two second handle 21 is provided at the bottom of the casing 1. The second axis 30 bottom end is fixed to the second handle 21 of the respective position, which is convenient to drive the threaded rod 12.
[0039]The implementation scenario is specifically: the staff rotates the second handle 21 to drive the second rotation 30 to rotate, and then drive the second cone gear 31 to rotate, since the second cone gear 31 meshes, the second cone gear 31 Rotating the first cone gear 17 to rotate, so that the threaded rod 12 is rotated, since the threaded rod 12 is threaded, the second connecting plate 19 restricts the thread sleeve 13 to rotate, so the threaded rod 12 rotates the threaded sleeve 13 horizontally, Thus, the second connecting plate 19 is moved horizontally, and the first connection plate 14 is moved horizontally, and the first connecting plate 14 is horizontally moved to move the pressing plate 15 horizontally, thereby releasing the fixation of the recording instrument, and takes out the recorder through the slot 16 Simple operation, easy to carry, and the second connecting plate 19 is horizontally movable to move the first slider 23 on the first slider 20, improve the stability of the threaded sleeve 13, by setting the limit block 18, limit the first slider 20 The movement distance, this embodiment has specifically solved the problem of inconvenient carrying in the prior art.
[0040]working principle:
[0041]Refer to the instructionsfigure 1 ,23 and 6, the staff turned the first handle 7 to drive the first rotating shaft 10 to rotate, which in turn can drive the test drum 11 to rotate, the patient observes the correction pattern on the test drum 11, the recording instrument in the box 1 records the patient's eye changes And by computer;
[0042]Refer to the instructionsfigure 1 ,2, 4, 5, and 7, the staff turns the second handle 21 to drive the second axis 30 to rotate, and then drive the first connection plate 14 horizontally, the first connecting plate 14 moves to move the extrudate plate 15 horizontally, thereby relieving The fixation of the recorder.
[0043]While the invention has been described in detail with the general description and specific embodiments, the present invention has been described, and some modifications or modifications can be made, which will be apparent to those skilled in the art. Therefore, these modifications or improvements made on the basis of the spirit of the invention are in the claims claims.
