Description

Technical Field

[0001] This utility model belongs to the technical field of vision correction devices, specifically relating to an adjustable-angle vision correction device. Background Technology

[0002] In the field of modern vision correction, the use of vision correction devices is becoming increasingly widespread. These devices play a vital role in helping users adjust their vision and correct eye problems. Vision correction devices typically include various adjustment functions to accommodate the different visual needs of users. However, existing vision correction devices have some technical shortcomings in angle adjustment, which affect the effectiveness and stability of the devices.

[0003] First, existing vision correction devices often face the problem of unstable angle fixation during adjustment. Traditional angle adjustment mechanisms typically rely on mechanical clamping or screw adjustment, which can lead to angle shifts after adjustment due to vibration, impact, or external interference. This not only affects the accuracy of vision correction but also causes inconvenience for users.

[0004] Secondly, some traditional vision correction instruments lack precise positioning during angle adjustment, failing to meet users' personalized vision correction needs. Due to the lack of effective positioning and locking mechanisms, these instruments often require recalibration or adjustment after each adjustment, increasing the complexity and time-consuming process.

[0005] Furthermore, existing adjustment devices often have complex structures, leading to inconvenience in operation or difficulty in maintenance. Many vision correction instruments require complicated disassembly and assembly procedures or additional tools, which frustrates users during actual use and reduces the overall user experience.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0022] like Figures 1 to 5 As shown, an adjustable-angle vision correction device includes a drive component 10 and an instrument component 20. The upper part of the drive component 10 is provided with a connecting part 11, and the lower two parts of the instrument component 20 are symmetrically provided with mounting parts 21. The two mounting parts 21 are respectively disposed on both sides of the connecting part 11. An adjustment component 30 is connected between the mounting part 21 and the connecting part 11, so that the drive component 10 and the instrument component 20 are hingedly connected through the adjustment component 30. In use, the instrument component 20 can be adjusted vertically through the adjustment component 30, thereby realizing the adjustment of the viewing angle of the vision correction device, which is convenient to use.

[0023] In practical implementation, the adjustment assembly 30 includes an adjustment mounting member 31, two adjustment mounting rings 32, and two adjustment positioning members 33. The adjustment mounting member 31 is installed in the connecting through-hole 21, the two adjustment mounting rings 32 are respectively connected to the two mounting through-holes 21, and the two adjustment positioning members 33 are respectively connected to the two adjustment mounting rings 32. Positioning spring rods 34 are provided on both sides of the adjustment mounting member 31, and positioning teeth 331 are provided on the outer edges of the opposite ends of the two adjustment positioning members 33. The ends of the positioning spring rods 34 are positioned and connected to the positioning teeth 331, thereby enabling the adjustment assembly 30 to adjust the position of the adjusting rings 31 ... The instrument component 20 is locatingly and adjustablely connected to the drive component 10. When the user adjusts the angle of the instrument component 20, the adjustment mounting part 31, the adjustment mounting ring 32, and the adjustment positioning part 33 of the adjustment assembly 30 work together. The movement and positioning between the positioning spring rod 34 and the positioning tooth 331 make the angle adjustment of the instrument component 20 precise. During the adjustment process, the interaction between the positioning spring rod 34 and the positioning tooth 331 achieves positioning and locking, which ensures that the angle of the instrument component 20 can be stably fixed after adjustment, avoiding angle deviation caused by vibration or external force interference.

[0024] The end of the positioning spring rod 34 is provided with a positioning protrusion 341 that is adapted to the positioning tooth 331. The positioning protrusion 341 is V-shaped and is engaged with the positioning tooth 331, thereby positioning and connecting the positioning spring rod 34 and the positioning tooth 331.

[0025] The inner ends of the connecting part 11 are symmetrically provided with fixed through posts 111, and the two sides of the adjusting mounting part 31 are symmetrically provided with fixed through grooves 311. The fixed through grooves 311 and the fixed through posts 111 are correspondingly provided, and the fixing parts are connected and fixed by fasteners passing through the fixed through grooves 311 and the fixed through posts 111, so that the adjusting mounting part 31 is fixedly installed in the connecting part 11. The structure is simple and the installation is convenient.

[0026] The inner sidewalls of the two mounting through-parts 21 are symmetrically provided with positioning blocks 211, and the sidewalls of the two adjusting mounting rings 32 are symmetrically provided with positioning grooves 321. The positioning grooves 321 correspond to the positioning blocks 211. When the adjusting mounting rings 32 are connected to the mounting through-parts 21, the positioning blocks 211 are respectively engaged in the positioning grooves 321 for positioning and connection. The inner two sides of the connecting through-parts 11 are symmetrically provided with fixing grooves 112, and the end edges of the two adjusting mounting rings 32 are respectively provided with fixing buckles 322. The fixing buckles 322 are respectively engaged in the fixing grooves 112 for fastening and fixing, so that the two adjusting mounting rings 32 are respectively positioned and fixedly connected in the two mounting through-parts 21. The structure is simple and the installation is stable and convenient.

[0027] Both adjustment mounting rings 32 have recessed connecting grooves 323 on their side walls, and both adjustment positioning members 33 have protruding connecting blocks 332 on their outer side walls. When the adjustment positioning member 33 is connected to the adjustment mounting ring 32, the connecting blocks 332 are engaged in the connecting grooves 323 to prevent the adjustment positioning member 33 from rotating during use.

[0028] In summary, the adjusting mounting component 31 is installed in the connecting through part 11, the adjusting mounting ring 32 is connected in the mounting through part 21, and the adjusting positioning component 33 is connected in the adjusting mounting ring 32. Positioning spring rods 34 are provided on both sides of the adjusting mounting component 31, and a positioning tooth 331 is provided on the outer edge of one end of the adjusting positioning component 33. The positioning spring rod 34 and the positioning tooth 331 are positioned and connected, allowing the instrument component 20 to be positioned and adjusted on the driving component 10. During the adjustment process, the interaction between the positioning spring rod and the positioning tooth in this adjustable angle vision corrector achieves positioning and locking, ensuring that the angle of the instrument component can be stably fixed after adjustment, avoiding angle deviation due to vibration or external force interference, and making it convenient to use.
