It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5As shown, the utility model provides an optical lens, comprising: a shell mechanism 1, a limiting mechanism 2 is arranged near the top of the shell mechanism 1, a lens assembly 3 is arranged near the bottom of the shell mechanism 1, the shell mechanism 1 comprises a circular shell 101, a light source board 102 is installed on the top of the circular shell 101, and slide grooves 103 are symmetrically opened near the bottom between the inner surface walls of the circular shell 101, and the inner surface walls on the opposite sides of the two slide grooves 103 are fixedly connected with a first spring 106, and the end of the first spring 106 is fixedly connected with a wedge block 105, the limiting mechanism 2 comprises a fixing ring 201, the fixing ring 201 is fixedly connected between the inner surface walls of the circular shell 101 near the top, and a plurality of telescopic rods 202 are fixedly connected at an equal distance from the bottom of the fixing ring 201, the light source board 102 is used to realize the color mixing and light mixing of R9 and R11 in the same lens, and the telescopic rods 20 2 is sleeved with a second spring 203, a squeeze ring 204 is fixedly connected between the bottom ends of the plurality of telescopic rods 202, the bottom of the squeeze ring 204 is inclined inwardly, the lens assembly 3 comprises a cone 301, a lens body 302 is arranged inside the cone 301, a first clamping ring 303 is fixedly connected to the outer surface of the cone 301 near the top, the top of the first clamping ring 303 is inclined inwardly, a plurality of limiting rods 304 are fixedly connected to the bottom of the first clamping ring 303 at equal intervals, a second clamping ring 305 is slidably connected between the outer surfaces of the plurality of limiting rods 304, the bottom of the second clamping ring 305 is inclined inwardly, the cone 301 is arranged inside the circular shell 101, the top of the first clamping ring 303 is fitted with the bottom of the squeeze ring 204, the first clamping ring 303 cooperates with the wedge block 105, and the second clamping ring 305 cooperates with the wedge block 105.

[0025] The effect achieved by the entire embodiment 1 is that the cone 301 and the lens body 302 form an optical lens body. When in use, the cone 301 is pressed from bottom to top into the inside of the circular shell 101. During the process, the surface and top of the first locking ring 303 outside the cone 301 will squeeze the wedge block 105 inside the circular shell 101 and the extrusion ring 204 above. After being squeezed, the wedge block 105 will slide into the inside of the slide groove 103 and squeeze the first spring 106 to contract, thereby allowing the first locking ring 303 to pass through. After the extrusion ring 204 is squeezed, the telescopic rod 202 and the second spring 203 are contracted, and then the cone 301 is released. At this time, the second spring 203 will exert a downward force on the extrusion ring 204 after rebounding, thereby cooperating with the wedge block 105 to move the first locking ring 303. A snap ring 303 is tightly pressed against, thereby completing the installation of the optical lens body. When removing, it is only necessary to squeeze and press the cone 301 downward so that the second snap ring 305 squeezes the wedge block 105 into the slide groove 103 and then moves to a position above the wedge block 105, and then release the cone 301. At this time, the first snap ring 303 and the second snap ring 305 are squeezed by the wedge block 105 and the squeezing ring 204 to form a ring with inclined top and bottom, and under the push of the second spring 203, the first snap ring 303 and the second snap ring 305 will simultaneously pass over the wedge block 105, thereby completing the removal of the optical lens body. The overall structure is simple, easy to disassemble and assemble, and the appearance is simple and generous. The light source board 102 is mainly used to provide a light source.

[0026] Embodiment 2, as Figure 2-Figure 4 As shown, the inner top and the inner bottom of the slide groove 103 are both provided with a limiting groove 104, the top and the bottom of the wedge block 105 near the first spring 106 are fixedly connected with the limiting block 107, and the limiting block 107 and the limiting groove 104 are slidably matched.

[0027] The effect achieved by the entire embodiment 2 is that when the second spring 203 pushes the extrusion ring 204 to move, the telescopic rod 202 is set to limit the extrusion ring 204, so that it can move up and down stably. The limit block 107 and the limit groove 104 are set to limit the wedge block 105, so that it can move to a specified distance and then form a match with the first locking ring 303 and the second locking ring 305. The overall structure is simple and easy to use.

[0028] Working principle: The cone 301 and the lens body 302 form an optical lens body. When in use, the cone 301 is pressed upward from bottom to top into the inside of the circular shell 101. During the process, the surface and top of the first snap ring 303 outside the cone 301 will squeeze the wedge block 105 inside the circular shell 101 and the squeezing ring 204 above. After being squeezed, the wedge block 105 will slide into the inside of the slide groove 103 and squeeze the first spring 106 to contract, thereby allowing the first snap ring 303 to pass through. After the squeezing ring 204 is squeezed, the telescopic rod 202 and the second spring 203 are contracted, and then the cone 301 is released. At this time, the second spring 203 will exert a downward force on the squeezing ring 204 after rebounding, thereby cooperating with the wedge block 105 to tightly press the first snap ring 303, thereby completing the installation of the optical lens body. When removing, you only need to squeeze and press the cone 301 downward so that the second snap ring 305 squeezes the wedge block 105 into the slide groove 103 After that, it moves to the position above the wedge block 105, and then the cone 301 is released. At this time, the first locking ring 303 and the second locking ring 305 are squeezed by the wedge block 105 and the extrusion ring 204 to form a ring with inclined top and bottom, and under the push of the second spring 203, the first locking ring 303 and the second locking ring 305 will simultaneously pass over the wedge block 105, thereby completing the removal of the optical lens body. The overall structure is simple, easy to disassemble and assemble, and the appearance is simple and generous. In addition, when the second spring 203 pushes the extrusion ring 204 to move, the telescopic rod 202 is set to limit the extrusion ring 204, so that it can move up and down stably. By setting the limit block 107 and the limit groove 104, the wedge block 105 is limited, so that it can move to a specified distance and form a match with the first locking ring 303 and the second locking ring 305. The overall structure is simple and easy to use.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
