[0032] This utility model proposes an ophthalmic examination device that, by employing a shielding component, allows the installation port to be opened or closed at any time, enabling maintenance personnel to inspect the specific condition of the rocker arm and replace it at any time. The device is simple to operate and practical.
[0033] Please see Figures 1 to 4 In one embodiment of this utility model, the ophthalmic examination device 10 includes:
[0034] Base 1;
[0035] Mounting housing 11, the mounting housing 11 is disposed on the base 1, the mounting housing 11 surrounds to form a receiving cavity 111 with an opening 112, the mounting housing 11 is provided with a mounting port on one side away from the base 1, the mounting port is located on one side of the opening 112;
[0036] Optometry component 2, one end of which extends into the receiving cavity 111 through the opening 112;
[0037] A driving component is disposed within the receiving cavity 111 and is driven and connected to the optometry component 2;
[0038] The control assembly includes a rocker arm 3 and a control component. One side of the rocker arm 3 is installed in the receiving cavity 111, and the other side of the rocker arm 3 protrudes from the mounting port. The control component is disposed in the receiving cavity 111 and is electrically connected to the rocker arm 3 and the drive assembly.
[0039] The shielding component 4 is detachably installed on the outer periphery of the mounting port.
[0040] In this embodiment, the ophthalmic examination device 10 includes a base 1, a mounting housing 11, an optometry component 2, a drive component, and a control component. The mounting housing 11 is disposed on the base 1 and forms a receiving cavity 111 with an opening 112. A mounting port is provided on the side of the mounting housing 11 facing away from the base 1, located on one side of the opening 112. One end of the optometry component 2 extends into the receiving cavity 111 through the opening 112. The drive component is disposed within the receiving cavity 111 and is connected to the optometry component 2 to drive the optometry component 2 to move up and down, facilitating optometry. The control component includes a rocker arm 3 and a control element. One side of the rocker arm 3 is mounted within the receiving cavity 111, while the other side passes through the mounting port. The control element is disposed within the receiving cavity 111 and is electrically connected to the rocker arm 3 and the drive component. This allows the operator to operate the rocker arm 3 to drive the optometry component 2.
[0041] Specifically, the ophthalmic examination device 10 also includes a shielding component 4, which is detachably mounted on the mounting housing 11 and covers the opening 112, allowing the mounting port to be opened or closed at any time. This enables maintenance personnel to easily check the condition of the rocker arm 3 and replace it as needed, making the operation simple and practical. It should be noted that the rocker arm 3 also passes through the shielding component 4 on the side that protrudes from the mounting port.
[0042] In one implementation, please refer to Figures 1 to 3 The shielding assembly 4 includes a shielding plate 41 and a locking member 42. The shielding plate 41 is used to shield the mounting port, and the locking member 42 is disposed on the shielding plate 41 to lock or release the shielding plate 41 to the mounting housing 11, thereby opening or closing the mounting port. This allows maintenance personnel to check the specific condition of the rocker arm 3 at any time and replace the rocker arm 3 at any time. The operation is simple and practical. It should be noted that the opening 112 of the mounting port needs to be large enough to facilitate the removal of the rocker arm 3 and other components from the mounting port. Similarly, the overall size of the shielding plate 41 needs to be larger than the opening 112 of the mounting port so as to completely cover the mounting port.
[0043] In one implementation, please refer to Figure 3 The baffle plate 41 has an opening 411 for the rocker arm 3 to pass through. By providing the opening 411 on the baffle plate 41, the rocker arm 3 can pass through the opening 411 and protrude from the mounting housing 11, so that the operator can operate the rocker arm 3.
[0044] In one implementation, please refer to Figure 3The locking member 42 includes a pushing block 421, two locking protrusions 422 and two locking blocks 423. The two locking protrusions 422 are arranged opposite each other on the outer periphery of the mounting opening. The middle position of the two locking blocks 423 is rotatably connected to the baffle plate 41. One side of the two locking blocks 423 is respectively located at both ends of the pushing block 421, and the other side of the two locking blocks 423 is movably connected to the two locking protrusions 422, so as to realize the detachable installation of the baffle plate 41 on the mounting housing 11 to open or close the mounting opening.
[0045] In this embodiment, the locking member 42 includes a pushing block 421, two locking protrusions 422, and two locking blocks 423. The two locking protrusions 422 are arranged opposite to each other on the outer periphery of the mounting opening, and the middle position of the two locking blocks 423 is rotatably connected to the baffle plate 41. That is, the two locking blocks 423 can rotate relative to the baffle plate 41. At the same time, one side of the two locking blocks 423 is respectively located at both ends of the pushing block 421, and the other side of the two locking blocks 423 is movably connected to the two locking protrusions 422. Therefore, by pushing the pushing block 421, the locking blocks 423 can be locked onto the locking protrusions 422 or separated from the locking protrusions 422, thereby realizing the locking or unlocking of the baffle plate 41.
[0046] In one implementation, please refer to Figure 3 Each of the locking blocks 423 is provided with a locking groove 4232 having a locking opening 4231 on the side away from the pushing block 421. The locking groove 4232 is engaged with the locking protrusion 422, thereby quickly and stably locking the locking block 423 onto the locking protrusion 422.
[0047] In one implementation, please refer to Figure 3 Each of the locking blocks 423 is gradually inclined at the end near the locking groove 4232 toward the locking opening 4231 of the locking groove 4232. This arrangement allows the locking blocks 423 to be quickly engaged with the locking protrusion 422 as they gradually approach it.
[0048] In one implementation, please refer to Figure 3 The locking member 42 further includes two elastic members 424 and a protrusion 425. The protrusion 425 is disposed on the baffle plate 41 and located between the two locking blocks 423. One side of each elastic member 424 is connected to one side of the protrusion 425, and the other side of each elastic member 424 is connected to one side of each locking block 423. By setting the elastic members 424, the locking block 423 can be stably engaged on the locking protrusion 422 to ensure that the baffle plate 41 can stably cover the installation opening.
[0049] In this embodiment, the locking member 42 further includes two elastic members 424 and a protrusion 425. The protrusion 425 is mounted on the baffle plate 41 and located on the two locking blocks 423. Simultaneously, one side of each elastic member 424 is connected to one side of the protrusion 425, and the other side of each elastic member 424 is connected to one side of the locking block 423. Therefore, when the locking block 423 is locked onto the locking protrusion 422, the locking block 423 can be stably locked onto the locking protrusion 422 under the elastic force of the two elastic members 424, thereby effectively preventing the locking block 423 from detaching from the locking protrusion 422. It should be noted that the elastic member 424 is a spring, but it can also be other elastic components; this application does not limit this.
[0050] In one implementation, please refer to Figures 1 to 3 Two locking members 42 are provided, and the two locking members 42 are arranged opposite to each other on the baffle plate 41. The two locking members 42 can stably lock the opposite sides of the baffle plate 41 onto the mounting housing 11.

[0052] In this embodiment, the annular seat 5 is detachably installed in the receiving cavity 111, that is, the annular seat 5 can be removed from the receiving cavity 111 at any time. It should be noted that the annular seat 5 can be detachably installed in the receiving cavity 111 by screws or the like, and an installation groove 51 is provided in the annular seat 5. Meanwhile, the rocker arm 3 includes a rod body 31 and a handle 32. One side of the rod body 31 is ball-jointed in the installation groove 51, while the other side of the rod body 31 protrudes from the installation opening, and the handle 32 is sleeved on the rod body 31, so that the rod body 31 can be driven to rotate by the handle 32.
[0053] In one implementation, please refer to Figure 4 The ophthalmic examination device 10 also includes two ball joint supports 6, which are detachably installed in the mounting groove 51. The two ball joint supports 6 are provided with ball joint holes, and one side of the rod body 31 passes through the mounting groove 51 and is ball jointed in the ball joint hole.
[0054] In this embodiment, to further facilitate the removal of the rocker arm 3 from the annular seat 5, the ophthalmic examination device 10 also includes two ball joint supports 6. The two ball joint supports 6 are detachably installed in the mounting groove 51, that is, the ball joint supports 6 can be removed from the receiving cavity 111 at any time.
