Description

Technical Field

[0001] This application relates to the field of optic head inspection and testing technology, and in particular to a portable optic head testing device. Background Technology

[0002] An optometry head is a device used to examine the convergence of light after it enters the eyeball. It uses emmetropia (normal vision) as a standard to measure the difference in convergence and divergence between the examined eye and the emmetropia of the normal eye. Over time, the optometry head's refraction data may become inaccurate, necessitating regular inspection to extend its lifespan.

[0003] In existing technologies, the inspection and testing of optic lenses must be carried out on-site at the manufacturer's or testing institution's location. This new method utilizes a desktop and single-arm stand for the optometry equipment, which is installed before inspection and testing. An optic lens testing device then evaluates the lenses of the optic lens. The spherical reflector of the optic lens testing device is fixed on a linear bearing and moves linearly, connected to a displacement sensor. The displacement data is transmitted to a computer system for processing and calculation.

[0004] Because optic lenses require regular testing, and each test must be conducted at the manufacturer's or testing facility's location, it is very inconvenient for users. Therefore, there is a need in this field to develop a portable optic lens testing device that is easy to carry. Utility Model Content

[0005] To address the inconvenience of having to travel to the manufacturer or testing institution to have the optic head inspected, this application provides a portable optic head testing device. The portable optic head testing device described herein mounts its main body on a portable three-dimensional mobile base, allowing for easy transport to the location of the optic head without requiring a trip to the manufacturer or testing institution, thus providing convenience for the optic head user.

[0006] To address the aforementioned technical problems, this application provides the following technical solutions.

[0007] In a first aspect, this application provides a portable optic head detection device, which includes a detection device body and a portable three-dimensional moving base, with the detection device body disposed on the three-dimensional moving base.

[0008] By adopting the above technical solution, the main body of the detection device is set on a portable three-dimensional moving base, making the detection device easy to carry. When the user needs to test the optic head, the detection device can be moved to the location of the optic head, the three-dimensional moving base can be placed on the platform, and then the mobility of the three-dimensional moving base can be used to align the main body of the detection device with the optic head. This improves the portability of the detection device while ensuring that the position can be adjusted anywhere.

[0009] Optionally, the portable refractory head detection device further includes a horizontal movement component, which comprises a slide rail, a slider, and a horizontal movement platform. The slide rail is fixedly connected to the three-dimensional moving base, the slider is slidably connected to the slide rail, one end of the horizontal movement platform is fixedly connected to the slider, and the other end of the horizontal movement platform is fixedly connected to the main body of the detection device. When the slider moves to one side of the slide rail, the horizontal movement platform extends beyond the three-dimensional moving base.

[0010] By adopting the above technical solution, the horizontal moving platform drives the main body of the detection device to move along the length of the slide rail with the slider, thereby adjusting the distance between the main body of the detection device and the lens of the optometry head, so that the distance between the main body of the detection device and the lens of the optometry head is as required by the user. Compared with the adjustment of the main body of the detection device along the length of the slide rail by the three-dimensional moving base, when the slider moves to one side of the slide rail, the horizontal moving platform extends beyond the three-dimensional moving base, making the adjustment range of the main body of the detection device along the length of the slide rail wider and improving the versatility of the detection device.

[0011] Optionally, the edge sidewall of the horizontal moving platform is provided with a folded edge, and the side of the folded edge closest to the horizontal moving platform is provided with a rounded corner.

[0012] By adopting the above technical solution, the folded edges and rounded corners on the horizontal moving platform make it less likely for the user to be scratched by the metal edges of the horizontal moving platform when pushing the platform to adjust the position of the main body of the detection device, thus improving the safety of the user when adjusting the position of the main body of the detection device.

[0013] Optionally, both ends of the slide rail are provided with limiting plates. When the slider approaches either end of the slide rail, the slider abuts against the corresponding limiting plate on the side of the slide rail closest to it.

[0014] By adopting the above technical solution, when the slider moves to either end of the slide rail, the slider abuts against the corresponding limiting plate on the side of the slide rail, preventing the slider from continuing to move out of the slide rail, avoiding the slider falling off the slide rail and causing damage to the main body of the detection device, and improving the safety of the detection device.

[0015] Optionally, a groove is provided on the side of the slider near the slide rail, the groove extends through both ends of the slider along the length of the slide rail, and a portion of the slide rail is filled in the groove.

[0016] By adopting the above technical solution, the slide rail is partially filled in the groove. When the slider slides on the slide rail, the movement of the slider along the width direction of the slide rail is restricted, so that the main body of the detection device moves smoothly along the length direction of the slide rail with the slider, thereby improving the stability of the main body of the detection device sliding along the slide rail.

[0017] Optionally, a screw is threaded onto the slider, with one end of the screw pressed against the side wall of the slide rail to fix the slider in place.

[0018] By adopting the above technical solution, when the slider moves to the required position, the rotating screw presses against the slide rail, which increases the friction between the slide rail and the slider, making the slider's movement easier to control and improving the precision and stability of the detection device's adjustment along the length of the slide rail.

[0019] Optionally, the end of the screw away from the slider is provided with a Torx hexagonal screw head.

[0020] By adopting the above technical solution, the rotation of the hexagonal screw head drives the screw to rotate synchronously, resulting in a larger rotation radius. The force required to achieve the same rotation speed is also smaller, eliminating the need for the user to use other tools to rotate the screw. This makes it easier for the user to hold the device and improves the convenience of locking the position of the main body of the detection device.

[0021] Optionally, the three-dimensional moving base is equipped with feet.

[0022] By adopting the above technical solution, the rubber material of the base enhances the friction between the three-dimensional moving base and the placement surface, making the detection device less prone to shifting or tipping over when swaying or subjected to pushing force, thus improving the stability of the detection device in use; on the other hand, when the detection device is subjected to external collisions, the base acts as a buffer, thereby reducing the vibration of the detection device and improving the safety of the detection device.

[0023] Optionally, the three-dimensional moving base is equipped with an adjustment handle.

[0024] By adopting the above technical solution, the main body of the detection device is moved in three-dimensional space by manipulating the adjustment handle, so that the main body of the detection device is aligned with the optometry head for optometry head detection, which improves the convenience for users to adjust the position of the main body of the detection device.

[0025] Optionally, the three-dimensional moving base is equipped with a power switch to control the on / off state of the current in the three-dimensional moving base.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The main body of the detection device is mounted on a portable three-dimensional mobile base, which makes the detection device easy to carry and improves its convenience;

[0028] 2. By sliding the horizontal moving platform on the slide rail synchronously, the main body of the detection device is moved, and the position of the main body of the detection device along the length of the slide rail is adjusted, which improves the versatility of the detection device;

[0029] 3. The movement distance of the slider is limited by the limiting plates at both ends of the slide rail, which prevents the slider from falling off the slide rail and causing damage to the main body of the detection device, thus improving the safety of the detection device.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a portable optometry head detection device.

[0036] Reference Figure 1 The portable optometry head detection device includes a three-dimensional moving base 1, a horizontal moving component 2, and a detection device body 3. The horizontal moving component 2 is mounted on the three-dimensional moving base 1 to adjust its position in three-dimensional space. The detection device body 3 is mounted on the horizontal moving component 2 so that when the movement of the detection device body 3 needs to exceed the adjustment distance of the three-dimensional moving base 1 for detection, the horizontal moving component 2 drives the detection device body 3 to move synchronously outside the three-dimensional moving base 1.

[0037] Reference Figure 1 The three-dimensional moving base 1 has four feet 11 on the side away from the main body 3 of the detection device, allowing the detection device to be stably placed on the platform. The feet 11 are made of rubber, providing cushioning force when the detection device is impacted. A power switch 12 is also located on one side of the three-dimensional moving base 1 to control the flow of current. To facilitate the positioning of the main body 3 in three-dimensional space, the three-dimensional moving base 1 has an adjustment handle 13. A mounting plate 14 is also located on the side of the three-dimensional moving base 1 closest to the main body 3 of the detection device for mounting the horizontal moving assembly 2.

[0038] Reference Figure 1 and Figure 2 The horizontal moving assembly 2 includes a slide rail 21, a slider 22, and a horizontal moving platform 24. The slide rail 21 and the mounting plate 14 are threaded together on the side away from the three-dimensional moving base 1. The slide rail 21 and the slider 22 are slidably connected. The slider 22 has a groove 221 on the side near the slide rail 21, which extends through both sides of the slider 22 along the length of the slide rail 21. The side of the slide rail 21 away from the three-dimensional moving base 1 abuts against the bottom of the groove 221 to restrict the movement of the slider 22 along the width direction of the slide rail 21. To prevent the slider 22 from easily detaching from the slide rail 21, both ends of the slide rail 21 have limiting plates 23. The end of the limiting plate 23 away from the slide rail 21 is bent and threadedly connected to the side of the mounting plate 14 near the three-dimensional moving base 1. When the slider 22 approaches either end of the slide rail 21, the slider 22 abuts against the corresponding limiting plate 23 on the side near the slide rail 21.

[0039] Reference Figure 1 and Figure 2 The slider 22 and one end of the horizontal moving platform 24 are connected by four bolts 243 to secure the connection. The other end of the horizontal moving platform 24 extends to the outside of the three-dimensional moving base 1 and is fixedly connected to the detection device body 3. When the movement of the detection device body 3 needs to exceed the adjustment distance of the three-dimensional moving base 1 for detection, the slider 22 drives the detection device body 3 to move towards the side of the slide rail 21 closer to the detection device body 3, so that the detection device body 3 moves outward from the three-dimensional moving base 1 along the length direction of the slide rail 21. To prevent the metal edge of the horizontal moving platform 24 from scratching the human body, the horizontal moving platform 24 has folded edges 241 on both sides along the width direction of the slide rail 21 and on the side away from the slider 22. The folded edges 241 have rounded corners 242 on the side closer to the horizontal moving platform 24. The horizontal moving platform 24 is a flat rectangular metal plate. The two ends of the horizontal moving platform 24 near the slider 22 along the width direction of the slide rail 21 also have notches 244 to facilitate bending of the edge of the horizontal moving platform 24.

[0040] Reference Figure 3 To make the movement of slider 22 along the length of slide rail 21 easier to control, a screw 222 is threaded onto slider 22. When one end of screw 222 is rotated and pressed against slide rail 21, the movement of slider 22 along the length of slide rail 21 is locked. A Torx head 223 is fixedly connected to the end of screw 222 away from slide rail 21. Torx head 223 drives screw 222 to rotate synchronously for easy grip by the user.

[0041] The implementation principle of a portable optic head detection device according to an embodiment of this application is as follows: turn on the power switch 12; operate the adjustment handle 13 to adjust the position of the detection device body 3 in three-dimensional space; if the adjustment of the three-dimensional moving base 1 along the length direction of the slide rail 21 is insufficient to meet the user's requirement for the distance between the detection device body 3 and the lens of the optic head, rotate the hexagonal screw head 223 to release the locking state of the horizontal moving platform 24, push the horizontal moving platform 24 to move along the length direction of the slide rail 21, and when the designated position is reached, rotate the hexagonal screw head 223 to lock the horizontal moving platform 24.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
