Description

Technical Field

[0001] This application relates to the technical field of optical lenses, and particularly to an optical lens assembly. Background Art

[0002] An optical lens is a lens made of optical glass. In optical research, an optical lens assembly is required. For example, two convex lens pieces are arranged in the same lens barrel. When two convex lenses with different degrees are overlapped and the distance between the two lenses is very small, it is equivalent to a convex lens with a higher degree. By appropriately changing the distance between the two convex lenses and then looking from the convex lens with a smaller degree to the convex lens with a larger degree, a telescope effect can be produced, and looking from the convex lens with a larger degree to the convex lens with a smaller degree can produce a microscope effect. The existing lens assemblies are not convenient for disassembling and replacing the lenses, especially the inner optical lens that can be moved to adjust the distance. Because it can move and adjust the distance in the lens barrel, its installation and disassembly are more inconvenient. Therefore, this application proposes an optical lens assembly.

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0028] As Figures 1-7 shown, an optical lens assembly proposed in an embodiment of the present application includes:

[0029] A lens barrel 1, one end of which is provided with an outer optical lens 2, and the other end is symmetrically provided with two straight grooves 3 communicating with the end face; the position of the outer optical lens 2 remains unchanged. Two arc-shaped blocks 4 can be enclosed to form a ring, and the ring is inserted and matched with the lens barrel 1. The outer wall of the ring is lapped with the inner wall of the lens barrel 1. Arc-shaped grooves 5 are opened on the inner walls of the two arc-shaped blocks 4. An inner optical lens 6 is movably inserted into the two arc-shaped grooves 5. Support rods 7 are provided on the outer walls of the two arc-shaped blocks 4, and the two support rods 7 respectively slide through the two straight grooves 3. When installing the inner optical lens 6, the two arc-shaped blocks 4 are buckled on the inner optical lens 6, so that the two arc-shaped blocks 4 enclose a ring, and the inner optical lens 6 is located in the two arc-shaped grooves 5. Then, the enclosed ring is movably inserted into the lens barrel 1, and the two support rods 7 are respectively slidably inserted into the two straight grooves 3. At this time, the lens barrel 1 limits the two arc-shaped blocks 4 so that the two arc-shaped blocks 4 cannot be separated, thereby installing the inner optical lens 6 in the lens barrel 1. At this time, the inner optical lens 6 and the outer optical lens 2 are kept parallel;

[0030] The adjusting cylinder 8 is rotatably sleeved on the lens barrel 1. At one end of the adjusting cylinder 8, two inclined slots 9 communicating with the end face are symmetrically opened. The end parts of the two support rods 7 respectively slide through the two inclined slots 9. When inserting the enclosed ring into the lens barrel 1, first rotate the adjusting cylinder 8 to align the openings of the two inclined slots 9 with the openings of the two straight slots 3 one by one. Then, when inserting the ring, when the support rod 7 is inserted into the straight slot 3, it is also synchronously inserted into the inclined slot 9. Then rotate the adjusting cylinder 8 again. Due to the inclined opening of the inclined slot 9, when the adjusting cylinder 8 rotates, the inclined slot 9 exerts a certain thrust on the support rod 7, enabling the ring to be pushed to slide horizontally along the axis of the lens barrel 1, thereby adjusting the distance between the inner optical lens 6 and the outer optical lens 2. When the adjusting cylinder 8 remains stationary, it can also limit the inner optical lens 6 to remain stationary. When it is necessary to remove the inner optical lens 6, only need to twist the adjusting cylinder 8 in the reverse direction to withdraw the ring from the lens barrel 1. When the ring is withdrawn from the lens barrel 1, the constraint of the lens barrel 1 on the ring is released, causing the ring to separate into two arc-shaped blocks 4, thereby taking out the inner optical lens 6, making the installation or removal of the inner optical lens 6 more convenient and fast;

[0031] In this solution, two arc-shaped blocks 4 are used to fasten the inner optical lens 6, and the ring enclosed by the two arc-shaped blocks 4 is inserted and matched with the lens barrel 1. By rotatably sleeving an adjusting cylinder 8 on the lens barrel 1 and using the insertion and matching of the support rod 7, the straight slot 3 and the inclined slot 9, it is not only convenient to move the inner optical lens 6 and adjust its distance from the outer optical lens 2, but also convenient to install or disassemble it.

[0032] As Figure 7 shown, in some embodiments, a slot 10 is opened on the outer surface of the lens barrel 1. An insertion rod 11 is movably inserted into the slot 10. A spring 12 is installed between the insertion rod 11 and the inner wall of the slot 10. The inner wall of the adjusting cylinder 8 is provided with a number of first teeth 13 distributed in a ring shape. The end of the insertion rod 11 is provided with a second tooth 14 that is engaged with the first teeth 13. Preferably, a tooth slot is formed between two adjacent first teeth 13, and the second tooth 14 is engaged with the tooth slot. In the initial state (under the elastic force of the spring 12), the second tooth 14 is engaged with the first teeth 13, thereby restricting the adjusting cylinder 8 from rotating freely. When it is necessary to twist the adjusting cylinder 8 to rotate, due to the inclined overlap of the first teeth 13 and the second teeth 14, therefore, only need to apply a certain force and twist the adjusting cylinder 8 forcefully to release its restriction and enable it to rotate. The overall structure of the device restricts the adjusting cylinder 8 from rotating freely due to a slight force, ensuring the stability of use. At the same time, when adjustment is needed, applying a certain force can adjust its rotation, thereby improving the practicality.

[0033] As Figure 5As shown, in some embodiments, first magnets 15 are provided at both ends of one of the arc-shaped blocks 4, and second magnets 16 are provided at both ends of the other arc-shaped block 4. The two first magnets 15 are magnetically engaged with the two second magnets 16 respectively. Embedding grooves are formed at both ends of the arc-shaped block 4, and the first magnet 15 or the second magnet 16 is embedded in the embedding groove. By providing the first magnet 15 and the second magnet 16 and utilizing their magnetic engagement, when the two arc-shaped blocks 4 are buckled on the inner optical lens 6, the two arc-shaped blocks 4 can be temporarily locked, so that the circular ring surrounded by the two arc-shaped blocks 4 can be more conveniently and quickly inserted and engaged with the lens barrel 1.

[0034] As Figure 5 shown, in some embodiments, first rubber pads 17 are provided on the inner walls of the two arc-shaped grooves 5. By providing the first rubber pads 17, it is used to protect the inner optical lens 6 and prevent the notch of the arc-shaped groove 5 from wearing the mirror surface of the inner optical lens 6.

[0035] As Figure 5 shown, in some embodiments, a sealing block 18 is fixed on the support rod 7. The sealing block 18 is inserted and engaged with the straight groove 3. Preferably, the length of the sealing block 18 is longer than the width of the inclined groove 9. Since the support rod 7 movably penetrates through the straight groove 3 and the inclined groove 9, and the straight groove 3 and the inclined groove 9 have an intersection point, by fixing the sealing block 18 on the support rod 7, the sealing block 18 is just located at the intersection point, which is used for sealing to prevent external dust from entering the air gap between the inner optical lens 6 and the outer optical lens 2, so as to ensure the imaging of the optical system.

[0036] As Figure 6 shown, in some embodiments, a first ring clamping block 19 is provided on the inner wall of one end of the lens barrel 1, and an installation ring 20 is threadedly sleeved on one end of the lens barrel 1. A second ring clamping block 21 is provided on the inner wall of the installation ring 20. The outer optical lens 2 is clamped between the first ring clamping block 19 and the second ring clamping block 21. When installing the outer optical lens 2, first place the outer optical lens 2 in the first ring clamping block 19, then threadedly sleeve the installation ring 20 on the lens barrel 1, and then twist the installation ring 20 so that the first ring clamping block 19 and the second ring clamping block 21 clamp and fix the outer optical lens 2, so that the installation or removal of the outer optical lens 2 only needs to twist the installation ring 20 to rotate, and the installation or removal is more convenient and quick.

[0037] As Figure 6As shown, in some embodiments, the second ring clamping block 21 is rotatably connected to the mounting ring 20. Preferably, an annular groove is formed in the inner wall of the mounting ring 20, and an annular block is formed on the second ring clamping block 21. The annular block is rotatably inserted into the annular groove, and the two are rotatably connected. When the mounting ring 20 is twisted and rotated, the second ring clamping block 21 does not need to rotate and only needs to move horizontally, avoiding rotational wear on the second ring clamping block 21 when it cooperates with the first ring clamping block 19 to fix the external optical lens 2, so as to protect the external optical lens 2.

[0038] As Figure 6 shown, in some embodiments, second rubber pads 22 are provided on the inner walls of the first ring clamping block 19 and the second ring clamping block 21. By providing the second rubber pads 22, wear on its mirror surface is avoided, and the protection effect on the external optical lens 2 is further improved.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
