DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 6 The present invention discloses an optical lens assembly with a stable structure, comprising a lens barrel 1, an inner cavity of the lens barrel 1 is provided with a mounting boss 2, an optical lens 3 is clamped on one side of the mounting boss 2, one end of the lens barrel 1 is threadedly connected with a positioning cylinder 4, one end of the positioning cylinder 4 presses and fixes the optical lens 3 on one side of the mounting boss 2, washers 23 are provided on both sides of the optical lens 3, and the sides of two groups of washers 23 away from the optical lens 3 are respectively in contact with the surfaces of the mounting boss 2 and the positioning cylinder 4.

[0028] In this embodiment, the optical lens 3 can be installed and fixed in the inner cavity of the lens barrel 1 by using the mounting boss 2 and the positioning tube 4. During installation, the user can first insert the optical lens 3 into the inner cavity of the lens barrel 1 so that one side of the optical lens 3 fits with the surface of the mounting boss 2. Then the user can tighten the positioning tube 4 so that one side of the positioning tube 4 is pressed against the surface of the optical lens 3. The optical lens 3 is pressed and fixed on the mounting boss 2 by the positioning tube 4. By setting the gasket 23, gaskets 23 are set on both sides of the optical lens 3 to protect its surface and prevent the positioning tube 4 from scratching its surface when it is pressed against the mounting boss 2.

[0029] Preferably, the inner cavity of the positioning tube 4 is detachably installed with a connecting tube 5, the inner cavity of the connecting tube 5 is fixedly installed with a fixing shell 6, a positioning ring 20 is fixedly installed at one end of the connecting tube 5, the inner cavity of the positioning ring 20 is provided with an annular groove 21, and a retaining ring 22 adapted to the annular groove 21 is fixedly installed at one end of the positioning tube 4, and the surface of the retaining ring 22 is engaged with the inner wall of the annular groove 21.

[0030] In this embodiment, the connecting tube 5 is detachable. When the optical lens assembly is not in use, the user can install and fix the connecting tube 5 in the inner cavity of the positioning tube 4, and seal one end of the optical lens module through the fixing shell 6 to prevent external dust from entering the inner cavity of the lens barrel 1 and adhering to the optical lens 3. When installing the connecting tube 5, the user can directly insert one end of the connecting tube 5 into the inner cavity of the positioning tube 4. When the annular groove 21 is stuck on the surface of the retaining ring 22, the connecting tube 5 will be clamped and fixed in the positioning tube 4.

[0031] Among them, the inner cavity of the fixed shell 6 is fixedly installed with a cleaning component for cleaning the surface of the optical lens 3, and the cleaning component includes a rotating shaft 7 rotatably installed in the inner cavity of the fixed shell 6, and the inner cavity of the fixed shell 6 and a side of the rotating shaft 7 is installed with a driving component for driving it to rotate, and the driving component includes a driving motor 9 fixedly installed in the inner cavity of the fixed shell 6, and the output shaft of the driving motor 9 is fixedly installed with a driving gear 10, and the surface of the rotating shaft 7 and at the corresponding position of the driving gear 10 is fixedly installed with a driven gear 11, and the driving gear 10 and the driven gear 11 are meshed with each other. A cleaning brush 8 is fixedly installed at one end of the rotating shaft 7, and one side of the cleaning brush 8 is in contact with the surface of the lens.

[0032] When the fixed shell 6 blocks one end of the lens barrel 1, the cleaning component inside it can also clean the surface of the optical lens 3. Specifically, the user can drive the driving gear 10 to rotate through the driving motor 9. The rotation of the driving gear 10 will drive the rotating shaft 7 to rotate through the driven gear 11, and then drive the cleaning brush 8 to rotate, and the surface of the optical lens 3 is cleaned by the cleaning brush 8. In addition, in this embodiment, a heat dissipation groove is opened on one side of the fixed shell 6 and at the corresponding position of the driving motor 9, which can discharge the heat generated by its operation to the outside.

[0033] It is worth mentioning that a positioning block 12 is fixedly installed in the inner cavity of the fixed shell 6, and a rotating hole 13 adapted to the rotating shaft 7 is opened on the surface of the positioning block 12. The surface of the rotating shaft 7 is rotatably connected to the inner wall of the rotating hole 13. By using the positioning block 12 and the rotating hole 13 in coordination, the stability of the rotation of the rotating shaft 7 can be improved. When the rotating shaft 7 rotates, its surface will rotate in the inner cavity of the rotating hole 13.

[0034] Furthermore, a guide slope 14 is provided on one side of the positioning block 12, and a dust collection assembly is installed in the inner cavity of the fixed shell 6 and at a position corresponding to the guide slope 14. The dust collection assembly includes a collection shell 15 slidably connected to the inner cavity of the fixed shell 6. Through the setting of the guide slope 14, part of the dust cleaned from the optical lens 3 will directly fall into the collection shell 15, and the other part will fall on the surface of the positioning block 12. Since the guide slope 14 is provided on one side of the positioning block 12, it can guide the dust and guide the dust into the collection shell 15.

[0035] Furthermore, a positioning assembly is provided on one side of the collecting shell 15 that penetrates the fixed shell 6 and extends to the outside of the fixed shell 6. The collecting shell 15 is installed and fixed to the inner cavity of the fixed shell 6 through the positioning assembly. The positioning assembly includes a positioning plate 16 fixedly installed on one side of the collecting shell 15. A positioning rod 17 is threadedly connected to one side of the positioning plate 16. One end of the positioning rod 17 penetrates the positioning plate 16 and extends to the outside of the positioning plate 16 and is threadedly connected to the surface of the fixed shell 6.

[0036] By setting the positioning component, the collecting shell 15 can be installed and fixed in the fixing shell 6. During installation, the user can directly insert the collecting shell 15 into the fixing shell 6. When it is fully inserted into the fixing shell 6, the positioning plate 16 on one side of it will fit with one side of the fixing shell 6. At this time, the user can tighten the positioning rod 17 to install and fix the positioning plate 16 on one side of the fixing shell 6, and then install and fix the collecting shell 15 in the fixing shell 6.

[0037] Furthermore, a countersunk hole 18 is provided on the surface of the positioning plate 16 and at the corresponding position of the positioning rod 17. One end of the positioning rod 17 is hidden in the inner cavity of the countersunk hole 18. Through the setting of the countersunk hole 18, when the positioning rod 17 is in a tightened state, one end of it will be hidden in the countersunk hole 18, thereby improving the flatness of the surface of the positioning plate 16. Limiting plates 19 are fixedly installed on both the upper and lower sides of the inner cavity of the fixed shell 6. The surface of the collection shell 15 is slidably connected to one side of the limiting plate 19. Through the setting of the limiting plate 19, the collection shell 15 can be limited to improve its movement stability. When the collection shell 15 moves, one side of it will be slidably connected to the surface of the limiting plate 19.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
