Detailed implementation manners

[0032] The following will explain in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0033] In the description of the present disclosure, unless otherwise stated, "inside and outside" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. used are to distinguish one element from another, and do not have sequentiality and importance.

[0034] In the description of the present disclosure, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "connected", "linked", "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0035] As Figures 1 to 4As shown in the figure, the present disclosure provides an ophthalmic detector that is easy to adjust, including a workbench 10, a detector body 20, a base 30, and a driving mechanism 40. The detector body 20 is installed on the base 30. A chute 11 penetrating through the top to the bottom is provided on the top of the workbench 10. The chute 11 has opposite first and second ends. The base 30 is slidably connected to the chute 11 and has a first position close to the first end and a second position close to the second end. The driving mechanism 40 includes a driving member 41 and a transmission assembly 42. The output shaft of the driving member 41 is in transmission connection with the base 30 through the transmission assembly 42, so that the base 30 can move on the workbench 10 along the length direction of the chute 11.

[0036] It can be understood that the two ends of the chute 11 extend respectively in the direction towards the patient and the direction away from the patient. Therefore, the first position refers to the position of the chute 11 close to the patient end, and the second position refers to the position of the chute 11 far from the patient end. Through the above technical solution, since the base 30 is slidably connected to the chute 11 and can move along the length direction of the chute 11, and the detector body 20 is installed on the base 30, the detector body 20 changes its position as the base 30 moves. In addition, through the provided transmission assembly 42, the power output by the driving member 41 is transmitted to the base 30 through the transmission assembly 42. That is, after the driving member 41 is started, the output shaft of the driving member 41 starts to rotate, and the rotational motion is converted into a linear motion through the transmission assembly 42 to push the base 30 to move along the length direction of the chute 11. That is to say, the position of the base 30 on the workbench 10 can be controlled by the driving mechanism 40 to adjust the distance between the detector body 20 and different patients, so as to obtain a better detection angle and distance, without the patient having to adjust their own position or always keep their upper body leaning forward for detection. Such a design is beneficial to improving the accuracy of detection and the comfort of the patient.

[0037] As an implementation manner, such as Figure 2As shown in the figure, the ophthalmic detector further includes two gears 50. The driving mechanism 40 further includes a chassis 43. The transmission assembly 42 includes a rack plate group 421, a first transmission rod 422, a second transmission rod 423, a driving bevel gear 424, and a driven bevel gear 425. The chassis 43 is installed at the bottom of the workbench 10. A cavity 431 is formed on the chassis 43. The driving member 41 is located outside the cavity 431. The two ends of the first transmission rod 422 are respectively rotatably connected to the inner wall of the cavity 431. The first transmission rod 422 extends in the horizontal direction. The axial direction of the output shaft of the driving member 41 is arranged at an angle with the axial direction of the first transmission member. One end of the second transmission rod 423 is connected to the output shaft of the driving member 41. A driving bevel gear 424 is sleeved on the other end of the second transmission rod 423. The driven bevel gear 425 is sleeved on the first transmission rod 422. The driving bevel gear 424 and the driven bevel gear 425 mesh with each other. The rack plate group 421 is installed at the bottom of the base 30 and includes two rack plates. The two rack plates are arranged at the same horizontal interval. A rack is provided on one side of each rack plate facing the first transmission rod 422. The two gears 50 are respectively located on both sides of the driven bevel gear 425 and are both sleeved on the first transmission rod 422. Each gear 50 meshes with the corresponding rack.

[0038] Among them, the chassis 43 is installed at the bottom of the workbench 10 and is used to accommodate the transmission assembly 42 and part of the driving mechanism 40, which can play a role in protecting the driving member 41 and the transmission assembly 42.

[0039] Among them, the driving member 41 can be configured as a motor, and the motor can be used as a power source.

[0040] Among them, the two ends of the first transmission rod 422 are rotatably connected to the inner wall of the cavity 431 of the chassis 43 and extend in the horizontal direction for transmitting torque.

[0041] Among them, one end of the second transmission rod 423 is connected to the output shaft of the driving member 41. A driving bevel gear 424 is sleeved on the other end of the second transmission rod 423. The driving bevel gear 424 meshes with the driven bevel gear 425 on the first transmission rod 422, converting the rotational force into a force along the axial direction of the first transmission rod 422, thereby realizing the transmission and direction conversion of the force. In addition, the driven bevel gear 425 drives the first transmission rod 422 to rotate, and the two gears 50 on the first transmission rod 422 rotate accordingly. The two gears 50 respectively mesh with the racks on the rack plates, converting the rotational motion into a linear motion of the rack plates in the horizontal direction. In this way, the movement of the rack plate group 421 drives the base 30 to move along the sliding groove 11 on the workbench 10, realizing the adjustment of the position of the ophthalmic detector body 20.

[0042] With such a design, through the precise cooperation between the gear 50 and the rack, the precise control of the position of the detector body 20 on the base 30 can be achieved, meeting different inspection requirements. Moreover, the combination of the bevel gear 50 and the transmission rod effectively converts and transmits power, reducing energy loss. In addition, the use of multiple gears 50 and rack plates ensures the smooth movement of the base 30, avoiding vibration interference during the detection process. In other words, through the ingenious combination of the gear 50, the rack plate and the bevel gear 50, the effective transmission and direction conversion of power can be realized, ensuring the stability, precision and smoothness of the ophthalmic detector during the adjustment process.

[0043] As an implementation manner, as Figures 1 to 4 shown, the chassis 43 includes a chassis main body 432 and a mounting portion 433 protruding from the chassis main body 432. A cavity 431 is formed inside the chassis main body 432. A receiving cavity 434 is formed inside the mounting portion 433. A through hole 435 communicating the receiving cavity 434 with the cavity 431 is formed on the mounting portion 433. The driving member 41 is received in the receiving cavity 434, and the output shaft of the motor or the second transmission rod 423 passes through the through hole 435.

[0044] Among them, for the part of the mounting portion 433 protruding from the chassis main body 432, a receiving cavity 434 is formed inside for arranging the driving member 41 (such as a motor). With such a design, on the one hand, since the driving member 41 (such as a motor) usually generates heat, therefore, arranging it independently helps with heat dissipation and can avoid overheating from affecting the performance of the transmission assembly 42. On the other hand, it can provide additional protection for the driving member 41, and at the same time physically isolate the driving member 41 from the transmission assembly 42, reducing the transmission of vibration and noise, which is beneficial to providing a quiet environment for the ophthalmology department. That is to say, by providing the mounting portion 433 and placing the driving member 41 in the protruding mounting portion 433, not only can the space layout be optimized, the compactness and stability of the overall structure of the driving mechanism 40 be improved, but also it is convenient for maintenance, thermal management and noise reduction.

[0045] As an implementation manner, as Figures 1 to 2 shown, the base 30 is configured as an "I"-shaped structure. The base 30 includes a connecting member 31 and a first mounting plate 32 and a second mounting plate 33 which are arranged oppositely up and down. The connecting member 31 passes through the sliding groove 11. The first end of the connecting member 31 is connected to the first mounting plate 32, and the second end of the connecting member 31 is connected to the second mounting plate 33. The bottom surface of the first mounting plate 32 is used to fit with the top surface of the workbench 10, and the top surface of the second mounting plate 33 is used to fit with the bottom surface of the workbench 10. Two rack plates are arranged on one side of the second mounting plate 33 away from the connecting member 31.

[0046] Among them, in scenarios where a large load needs to be borne or vibrations are generated during operation, the design of this "I"-shaped base 30 can effectively improve the stability of the detector.

[0047] As an implementation manner, as Figure 1 and Figure 4 shown, the ophthalmic detector further includes a support plate 60 and a mounting sleeve 70. A detector body 20 is disposed on the top of the support plate 60, and a first mounting member 61 is disposed on the bottom of the support plate 60. A second mounting member 331 is disposed on the top of the base 30 (here referring to the first mounting plate 32). The first mounting member 61 and the second mounting member 331 are respectively detachably connected to two ends of the mounting sleeve 70.

[0048] Through the detachable connection between the first mounting member 61 and the second mounting member 331 and the mounting sleeve 70, the ophthalmic detector can be conveniently installed and disassembled, which is beneficial to the transportation, storage and maintenance of the instrument. In addition, such a design can also adjust the height of the detector according to the patient's needs to adapt to patients of different heights or optimize the layout of the working space.

[0049] As an implementation manner, as Figure 4 shown, the mounting sleeve 70 includes a connected first mounting sleeve 71 and a second mounting sleeve 72. The top of the first mounting sleeve 71 is used to sleeved on the first mounting member 61. The bottom of the first mounting sleeve 71 is connected to the top of the second mounting sleeve 72. The bottom of the second mounting sleeve 72 is used to sleeved on the second mounting member 331. A first opening 711 is formed on the side wall of the first mounting sleeve 71. Symmetric first clamping plates 712 are disposed on both sides of the first opening 711. The two first clamping plates 712 are connected by a first adjusting bolt 713. A second opening 721 is formed on the side wall of the second mounting sleeve 72. Symmetric second clamping plates 722 are disposed on both sides of the second opening 721. The two second clamping plates 722 are connected by a second adjusting bolt 723.

[0050] With such a design, the detector body 20 can have a certain adjustment range in the vertical direction to adapt to patients of different heights. At the same time, by controlling the tightness of the clamping plates with the adjusting bolts, the stability and reliability of the connection between the first mounting member 61 and the mounting sleeve 70 and between the second mounting member 331 and the mounting sleeve 70 can be ensured.

[0051] As an implementation manner, as Figures 1 to 2 shown, the ophthalmic detector further includes a support plate 80. The support plate 80 is disposed on the support plate 60. The support plate 80 includes support legs 81 and a support portion 82. An arc-shaped groove 83 is formed on the support portion 82. The groove surface of the arc-shaped groove 83 is used to fit with the patient's chin.

[0052] Among them, the support legs 81 are used to connect the support plate 80 and the support plate 60 of the detector, which can play a role in load-bearing and fixing, and can ensure that the support plate 80 is stably positioned at an appropriate height and angle.

[0053] Among them, the groove surface radian of the arc-shaped groove 83 is designed according to ergonomic principles, which can adapt to the curves of the chins of different patients and provide a personalized comfortable experience. When the patient places the chin in the groove, it can provide a certain degree of stability during the detection process, reduce head movement, and ensure the accuracy of the detection data.
