"Multiple" means two or more, unless otherwise clearly and specifically defined.

[0045] like Figure 1 、 Figure 2 As shown, this embodiment proposes a position-adjustable detection frame for an ophthalmometer, which is used to detect a comprehensive ophthalmometer 10, wherein the position-adjustable detection frame mainly includes: a Y-direction drive assembly 200, a Z-direction drive assembly 300, an X-direction drive assembly 400 and a connecting rod 500. For the convenience of structural description, the direction facing the operator is the Y-direction (front-back direction), the direction of the operator's left and right hands is the X-direction (left-right direction), and the height direction of the vertical placement of the position-adjustable detection frame is the Z-direction (up-down direction). The various components of this embodiment are structurally described based on this direction standard. The Y-direction drive assembly 200 of this embodiment extends along the Y-direction and has a certain length in the front-back direction. The Z-direction drive assembly 300 is arranged on the Y-direction drive assembly 200 and moves along the Y-direction by the drive of the Y-direction drive assembly 200. The X-drive assembly 400 is mounted on the Z-drive assembly 300 and moves in the Z direction when driven by the Z-drive assembly 300. The connecting rod 500 is connected to the X-drive assembly 400 and moves in the X direction when driven by the X-drive assembly 400. One end of the connecting rod 500 forms a connecting portion 520, which is used for detachably connecting and testing the phoropter 10. The phoropter 10 to be tested is mounted on the connecting portion 520 of the connecting rod 500, so that the testing equipment can detect the phoropter 10. When the position of the phoropter 10 needs to be adjusted, the phoropter 10 is adjusted in the front-to-back, up-down, and left-to-right directions by the Y-drive assembly 200, the Z-drive assembly 300, and the X-drive assembly 400, respectively, to achieve the purpose of testing different positions of the phoropter 10.

[0046] like Figure 1 、 Figure 2 As shown, the position-adjustable testing stand for a comprehensive ophthalmometer of this embodiment is provided with a Y-drive assembly 200, a Z-drive assembly 300, and an X-drive assembly 400. During the testing process of the comprehensive ophthalmometer 10, the comprehensive ophthalmometer 10 is connected to the connecting portion 520 of the connecting rod 500. The comprehensive ophthalmometer 10 can be moved in the front-to-back direction by the Y-drive assembly 200, the comprehensive ophthalmometer 10 can be moved in the up-down direction by the Z-drive assembly 300, and the comprehensive ophthalmometer 10 can be moved in the left-to-right direction by the X-drive assembly 400. Therefore, when it is necessary to test whether different positions of the comprehensive ophthalmometer 10 are qualified, the position-adjustable testing stand of this solution can be used to move the comprehensive ophthalmometer 10 in the front-to-back, left-to-right, and up-to-down directions, without the operator having to manually move it. This not only achieves accurate movement of the moving position, but also saves time and effort, making the testing process of the comprehensive ophthalmometer 10 more convenient.

[0047] like Figure 1 As shown, the position-adjustable testing frame of this embodiment further includes a table base 100, with the Y-axis drive assembly 200 fixedly mounted on the table base 100. The table base 100 can be a square structure, and counterweights can be provided through the table base 100, thereby providing more stable structural support for the position-adjustable testing frame. When the phoropter 10 to be tested is connected to the connecting rod 500, the stable support of the table base 100 prevents the adjustable testing frame from collapsing, thereby improving structural stability.

[0048] like Figure 1 、 Figure 2 As shown, the Y-axis drive assembly 200 of this embodiment specifically includes: a Y-axis base 210, a Y-axis screw assembly 220, a Y-axis handle 230, and a Y-axis slide 240. The Y-axis base 210 extends a predetermined length in the Y-axis direction and is fixedly connected to the table base 100. Specifically, a guide shaft is provided on the Y-axis base 210 extending in the Y-axis direction. The Y-axis screw assembly 220 is connected to the Y-axis base 210. Bearings can be provided at the front and rear ends of the Y-axis base 210 so that the Y-axis screw assembly 220 is embedded in the bearings and can rotate on the Y-axis base 210. The Y-axis slide 240 is connected to the Y-axis screw assembly 220 and is slidably connected to the guide shaft. In this way, the Y-axis slide 240 moves back and forth on the Y-axis base 210 through the rotation of the Y-axis screw assembly 220. The Y-handle 230 is connected to one end of the Y-screw assembly 220 via a coupling, and is manually cranked to rotate the Y-screw assembly 220. The Z-drive assembly 300 is connected to the Y-slide 240. When the Y-handle 230 is cranked, the Y-screw assembly 220 rotates, which in turn drives the Y-slide 240 forward and backward along the extension of the guide shaft, thereby moving the Z-drive assembly 300 forward and backward, thereby enabling the phoropter 10 to move forward and backward by manual cranking.

[0049] like Figure 1 、 Figure 2As shown, further, a Y-axis locking member 250 is provided on the Y-axis base 210 of this embodiment, and the Y-axis screw assembly 220 is locked or unlocked by the Y-axis locking member 250. The Y-axis locking member 250 is typically a screw handle provided on a self-locking block with a C-shaped opening. Twisting the handle tightens the C-shaped opening, thereby compressing the shaft of the Y-axis screw assembly 220, which is inserted into the C-shaped opening, and preventing the Y-axis screw assembly 220 from rotating, thereby achieving the purpose of manual locking (the Y-axis locking member 250 is a conventional self-locking structure for a slide). After the phoropter 10 is moved to a predetermined position in the fore-aft direction by manually cranking the Y-axis handle 230, the Y-axis locking member 250 locks the Y-axis screw assembly 220, thereby locking the fore-aft position of the phoropter 10. This prevents displacement in this direction during the testing process, thereby achieving accurate positioning.

[0050] like Figure 2 、 Figure 3 As shown, further, the Z-axis drive assembly 300 of this embodiment specifically includes: a gear box 310, a gear set 320, a second rotating shaft 330, a Z-axis handle 340, a Z-axis screw assembly 350, and a Z-axis slide 360. The gear box 310 is connected to the Y-axis slide 240 of the Y-axis drive assembly 200. A Z-axis support 370 is connected to the gear box 310. The Z-axis support 370 extends a predetermined length in the vertical direction. L-shaped connecting plates 371 are provided on the left and right sides of the lower end of the Z-axis support 370. Half of the L-shaped connecting plate 371 is fixed to the Z-axis support 370 by screws, and the other half is fixed to the gear box 310 by screws, so that the Z-axis support 370 can stand stably on the gear box 310. The second rotating shaft 330 rotates and is inserted into the gear box 310. The Z-direction handle 340 is located on the outside of the gear box 310 and is connected to the second rotating shaft 330. The Z-direction screw assembly 350 is arranged on the gear box 310 and the Z-direction support 370. The gear set 320 is arranged in the gear box 310 and is connected to the second rotating shaft 330 and the Z-direction screw assembly 350. The gear set 320 uses a pair of bevel gears to change direction during the transmission process. The Z-direction slide 360 is movably arranged on the Z-direction support 370 and is connected to the Z-direction screw assembly 350. The rack box 410 is connected to the Z-direction slide 360. Similarly, a guide shaft is arranged on the Z-direction support 370 in the up and down directions. The Z-direction slide 360 is slidably arranged on the guide shaft and can slide in the up and down directions. When the Z-axis handle 340 is shaken, the Z-axis screw assembly 350 is driven to rotate through the gear set 320, and the rotating Z-axis screw assembly 350 drives the Z-axis slide 360 to move up and down along the extension direction of the guide shaft, thereby driving the X-axis drive assembly 400 thereon to move up and down, thereby enabling the comprehensive ophthalmometer 10 to move up and down by hand shaking.

[0051] In the specific structure, the second rotating shaft 330 is provided on the gear box 310 in the left-right direction, so that the Z-direction handle 340 is located outside the gear box 310 in the left-right direction, making it convenient for the operator to shake the handle from the outside in the left-right direction.

[0052] like Figure 2 、 Figure 3 As shown, the gearbox 310 of this embodiment is further provided with a Z-locking member 380, and the Z-screw assembly 350 is locked or unlocked by the Z-locking member 380. In the specific structure, the Z-locking member 380 is disposed within the gearbox 310. After the phoropter 10 is moved vertically to a predetermined position by manually cranking the Z-handle 340, the Z-locking member 380 locks the Z-screw assembly 350. This locks the vertical position of the phoropter 10, preventing it from shifting in this direction during the testing process, thereby achieving accurate positioning.

[0053] like Figure 2 As shown, in this embodiment, the gear box 310 is provided with an installation window 311, and the Z-direction locking member 380 includes a Z-direction locking handle 381. The Z-direction locking handle 381 is located outside the gear box 310 and enters the gear box 310 through the installation window 311. This allows the Z-direction locking handle 381 to extend outside the gear box 310, making it easier for the operator to perform the locking operation.

[0054] like Figure 1 、 Figure 2 、 Figure 4 As shown, the X-axis drive assembly 400 of this embodiment specifically includes: a rack box 410, a first rotating shaft 420, an X-axis handle 430, and a first gear 440. The rack box 410 is connected to the Z-axis slide 360 of the Z-axis drive assembly 300. The first rotating shaft 420 rotates and passes through the rack box 410. The X-axis handle 430 is located outside the rack box 410 and is connected to the first rotating shaft 420. The first gear 440 is located inside the rack box 410 and is connected to the first rotating shaft 420. A rack 510 is provided on the connecting rod 500, which passes through the rack box 410 along the X direction so that the rack 510 and the first gear 440 are meshed. When the X-handle 430 is shaken, the rack 510 on the connecting rod 500 is driven by the rotation of the first gear 440, thereby driving the connecting rod 500 to move in the left and right directions, thereby moving the comprehensive ophthalmometer 10 thereon in the left and right directions, and then the comprehensive ophthalmometer 10 can be moved left and right by hand shaking.

[0055] like Figure 2 、 Figure 4As shown, in the specific structure, the first rotating shaft 420 is provided on the rack box 410 along the front-to-back direction, so that the X-direction handle 430 is located outside the rack box 410 in the front-to-back direction, which is convenient for the operator to shake the handle from the outside in the front-to-back direction.

[0056] like Figure 1 、 Figure 2 、 Figure 4 As shown, in this embodiment, an X-locking member 450 is further provided on the outer wall of the rack housing 410. The connecting rod 500 is inserted through the X-locking member 450 and is locked or unlocked by the X-locking member. After the phoropter 10 is moved to a predetermined position in the left-right direction by manually cranking the X-handle 430, the connecting rod 500 is locked by the X-locking member 450. This locks the phoropter 10 in the left-right direction, preventing it from shifting in this direction during the inspection process, thus achieving accurate positioning.

[0057] Furthermore, the connecting portion 520 can be provided in different forms according to different requirements. For example, the connecting portion 520 can be directly the end of the connecting rod 500 (such as Figure 1 、 Figure 4 As shown), the installation process of the comprehensive ophthalmometer 10 can be achieved by putting the mounting hole (optical hole) of the comprehensive ophthalmometer 10 on the end of the connecting rod 500 and locking it with a screw.

[0058] However, the specifications of the mounting holes used in the comprehensive ophthalmometers 10 of different specifications are different, and some comprehensive ophthalmometers 10 even have the mounting holes directly set as threaded holes. In this way, it is necessary to adopt a replaceable connecting portion 520 structure to realize the detection of comprehensive ophthalmometers 10 of different specifications.

[0059] like Figure 1 、 Figure 5 As shown, the connecting portion 520 of this embodiment includes an adapter 530, one end of which is used to be detachably connected to the end of the connecting rod 500 and the other end is used to be detachably connected to the phoropter 10. The adapter 530 has different specifications and is adapted to different models of phoropter 10 by being detachably connected to the connecting rod 500. Multiple adapters 530 of different specifications can be provided, and one end of the multiple adapters 530 adopts the same standard, so that the same socket hole 531 is provided on the end. In this way, the adapter 530 can be connected to the end of the connecting rod 500 through the socket hole 531 and locked by screws on the outer wall of the adapter 530. The other ends of the multiple adapters 530 adopt different structures, for example, they can be inserted into the mounting hole of the phoropter 10 with different sizes. In this way, the other ends of the multiple adapters 530 are used for detachable insertion into the mounting hole of the phoropter 10. Different specifications of adapters 530 are selected according to different mounting structures of the phoropter 10.

[0060] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
