During the assembly process, the position of the lens assembly is controlled and the lens is assembled in the most ideal position in the optical path to achieve the purpose of optimizing the optical path performance.

[0033] There is a method of adding multiple fixed blocks to affect each other so as to adjust the lens in two dimensions within the lens barrel. However, this method basically only has an adjustment function and does not have other functions, resulting in limited application.

[0034] The utility model provides a stable structure, which is intended to achieve stable adjustment of optical lenses.

[0035] See also Figures 1 to 5 In one embodiment of the present invention, the stabilizing structure is used for lenses, and the stabilizing structure 100 includes a mounting seat 1 and a fixing structure 3.

[0036] The technical solution of the present invention is to install the lens by adopting the installation station 2. By utilizing the setting of the mounting seat 1, the installation station 2 can be adjusted along its height direction on the mounting seat 1 to achieve different position requirements of the lens during processing. By arranging the fixing structure 3 between the mounting seat 1 and the installation station 2, the installation station 2 can be pressed and fixed when the position of the installation station 2 is adjusted on the mounting seat 1 to eliminate the fitting jitter caused by the processing tolerance of parts, so that the lens can be stably adjusted. After the lens position is adjusted, the installation station 2 can be effectively locked, so that the lens position is better maintained, which is suitable for application on the product, thereby improving the application surface.

[0037] The adjustment method of the installation station 2 can be manual, which saves structural layout, or automatic, which is more accurate and saves trouble compared to manual adjustment. For specific setting methods, please refer to the following description.

[0038] There are many ways to set up the clamping part 31. It can be a spring or an elastic telescopic rod. The installation method of the clamping part 31 can be to be movably extruded and set between the mounting seat 1 and the mounting station 2 to press the mounting station 2; it can be fixed inside the mounting seat 1 to press the mounting station 2; it can also be fixed inside the mounting station 2 to press the mounting seat 1. Please refer to the following description for specific setting methods.

[0039] In this embodiment, there is no specific limitation on the number of the pressing parts 31 , which can be one or more.

[0040] Taking into account the requirement for stable adjustment of the mounting station 2, in the technical solution of the present invention, multiple pressing parts 31 are selected to be set on the mounting seat 1 to press corresponding to the position adjusted by the mounting station 2; and / or, multiple pressing parts 31 are selected to be set on the mounting station 2, so that the pressing parts 31 are pressed toward the mounting seat 1; in this way, multiple pressing parts 31 can be selected to be set on the mounting seat 1; multiple pressing parts 31 can be selected to be set on the mounting station 2, or multiple pressing parts 31 can be selected to be set on the mounting seat 1 and the mounting station 2 respectively. In this embodiment, multiple pressing parts 31 are selected to be set on the mounting seat 1 and the mounting station 2 respectively, so that the lens can receive the pressing pressure of the pressing parts 31 from different directions, so that the mounting station 2 can fit tightly with the mounting seat 1 to eliminate the fitting jitter caused by the part processing tolerance, so that the lens can achieve stable adjustment.

[0041] It should be explained that the connection between each pressing portion 31 and the mounting seat 1 and the mounting station 2 is a fixed connection.

[0042] Furthermore, the clamping portion 31 includes a spring 311 and an abutment 312 connected to the spring 311, and the outer peripheral wall of the abutment 312 contacts the installation station 2 to abut toward the installation station 2; in this way, the spring 311 can be fixed to the inner wall of the mounting seat 1, and the spring 311 provides elastic force for the abutment 312. After the abutment 312 is subjected to the force, it abuts against the installation station 2, thereby absorbing the vibration of the installation station 2 during adjustment, thereby achieving stable adjustment of the installation station 2.

[0043] The abutment member 312 may be provided in the form of an abutment ball.

[0044] Furthermore, in order to improve the stability of the spring 311, in the technical solution of the present invention, the clamping part 31 also includes a support tube 313, and the spring 311 is located inside the support tube 313; in this way, the setting of the support tube 313 provides a support position for the spring 311 while limiting the stretching direction of the spring 311, so that the tension direction of the spring 311 becomes stable, thereby achieving the purpose of stable abutment against the installation station 2.

[0045] It should be explained that one end of the spring 311 is fixed to the inner wall of the support tube 313 , and the other end is fixed to the abutment 312 . The abutment 312 can also be retracted into the interior of the support tube 313 by the spring 311 .

[0046] In addition, in order to facilitate the position adjustment of the installation station 2 , the stabilizing structure 100 further includes an installation rail 4 .

[0052] The fixing seat 51 may be placed on a side close to the mounting rail 4 .

[0053] The transmission part 55 may be provided in the form of a transmission shaft. Considering that the transmission shaft directly drives the installation station 2 to adjust, the setting of the pressing part 31 may cause a jam.
