Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical lens technology, and more specifically, to a split optical lens. Background Technology
[0002] A split-type optical lens typically consists of a first split optical lens and a second split optical lens, which are physically connected by a connecting frame and a snap-fit device.
[0003] In the prior art, application number 202222266029.7 discloses a split optical lens, including a lens barrel, a connector, and a fixing base. The fixing base has a first threaded groove inside, and the right end of the connector is threaded into the first threaded groove. The other end of the connector has a second threaded groove, and the right side of the lens barrel has a third threaded groove. The second threaded groove and the third threaded groove are threaded together. The two sides of the lens barrel have first limiting grooves. The connector has a cavity inside, and a first limiting mechanism is connected inside the cavity and matches the corresponding first limiting groove. The above device requires a large number of threaded structures for assembly and connection. In particular, the threaded structure of the lens cap will wear and strip after long-term use. In addition, during the lens assembly process, relying solely on the threaded structure for assembly is not stable and accurate enough, and the optical lenses of the split lens are prone to misalignment. Using springs for limiting and fixing is prone to vibration due to the characteristics of the springs, which greatly reduces stability.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a split optical lens to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A split optical lens includes a lens barrel and a mounting tube. The lens barrel is fitted and fixed inside the mounting tube. A lens end cap is connected to the top side of the lens barrel. A locking structure is connected to the outside of the mounting tube. A threaded connecting tube is connected inside the locking structure.
[0008] Preferably, the lens end cap includes a ring body and connecting posts, the connecting posts being equidistantly disposed on the bottom edge of the ring body, and a positioning tube being sleeved on the outside of the connecting posts.
[0009] Preferably, the bottom end of the positioning tube is fixedly connected to the top of the locking structure, and the connecting column is specifically a rubber structure that is sealed and fitted into the inner wall of the positioning tube.
[0010] Preferably, the locking structure includes a limiting ring, a connecting ring, and a fixing ring. The bottom edge of the limiting ring is fixedly connected to the connecting ring, and the interior of the fixing ring is connected to the outer wall of the connecting ring through a bearing.
[0011] Preferably, the outer wall of the mounting tube is movably sleeved with the inner wall of the limiting ring, and a threaded groove is provided on the inner wall of the fixing ring. The fixing ring is threadedly connected to the outer wall of the threaded connecting tube through the threaded groove.
[0012] Preferably, the inner wall of the limiting ring is connected with limiting protrusions at equal intervals, and the inner wall of the mounting tube is provided with a limiting groove, which penetrates the bottom side of the mounting tube. The limiting protrusions and the limiting groove are slidably engaged.
[0013] The beneficial effects of this utility model are as follows: the lens end cap can be assembled and disassembled by plugging, avoiding the unsmooth disassembly of the lens end cap due to damage to the threads caused by using a threaded connection structure, and avoiding the accidental contact and wear of the optical lens caused by repeated twisting of the lens end cap. While assembling the mounting tube and the threaded connection tube, the stability of the lens barrel assembly inside the mounting tube can be further improved, and the internal optical lens can be prevented from shifting due to the rotation of the lens barrel.

[0021] According to an embodiment of the present invention, a split optical lens is provided.
[0022] Example 1
[0023] like Figure 1-3 As shown, a split optical lens according to an embodiment of the present invention includes a lens barrel 1 and a mounting tube 2. The lens barrel 1 is fitted and fixed inside the mounting tube 2. A lens end cap 3 is connected to the top side of the lens barrel 1. A locking structure 4 is connected to the outside of the mounting tube 2. A threaded connecting tube 5 is connected inside the locking structure 4. The lens end cap 3 includes a ring body 6 and connecting posts 7. The connecting posts 7 are equidistantly arranged on the bottom edge of the ring body 6. A positioning tube 8 is fitted to the outside of the connecting posts 7. The bottom end of the positioning tube 8 is fixedly connected to the top of the locking structure 4. The connecting posts 7 are specifically rubber structures and are sealed and fitted with the inner wall of the positioning tube 8. After the lens end cap 3 is connected and attached to the top of the lens barrel 1, the lens end cap 3 is respectively set inside the positioning tube 8 through the connecting posts 7. While the positioning tube 8 protects the outside of the mounting tube 2, the lens end cap 3 can be assembled and disassembled by plugging in. This avoids the problem of the lens end cap 3 being difficult to disassemble due to damage to the threads when using a threaded connection structure, and also avoids the situation where the optical lens is accidentally contacted and worn due to repeated twisting of the lens end cap 3.
[0024] Example 2
[0025] like Figure 1-3As shown, a split optical lens according to an embodiment of the present invention includes a lens barrel 1 and a mounting tube 2. The lens barrel 1 is sleeved and fixed inside the mounting tube 2. A lens end cap 3 is connected to the top side of the lens barrel 1. A locking structure 4 is connected to the outside of the mounting tube 2. A threaded connecting tube 5 is connected inside the locking structure 4. The locking structure 4 includes a limiting ring 9, a connecting ring 10, and a fixing ring 11. The bottom edge of the limiting ring 9 is fixedly connected to the connecting ring 10. The inside of the fixing ring 11 is connected to the outer wall of the connecting ring 10 through a bearing. The outer wall of the mounting tube 2 is movably sleeved with the inner wall of the limiting ring 9. A threaded groove is carved on the inner wall of the fixing ring 11. The fixing ring 11 is threadedly connected to the outer wall of the threaded connecting tube 5 through the threaded groove. Limiting protrusions 12 are connected annularly at equal intervals on the inner wall of the limiting ring 9. A threaded groove is carved on the inner wall of the mounting tube 2. There is a limiting groove 13 that penetrates the bottom side of the mounting tube 2. The limiting protrusion 12 slides and engages with the limiting groove 13. When the lens barrel 1 is fitted into the threaded connecting tube 5 through the mounting tube 2, and then the fixing ring 11 is screwed on, the fixing ring 11 can keep the limiting ring 9 stationary under the action of the connecting ring 10 connected by the bearing. The fixing ring 11 is screwed down to connect and fix the mounting tube 2 and the threaded connecting tube 5. At the same time as the fixing ring 11 is screwed on, the limiting protrusion 12 on the inner wall of the limiting ring 9 slides and engages with the limiting groove 13 on the outer wall of the mounting tube 2. This can further improve the stability of the assembly of the lens barrel 1 inside the mounting tube 2 while the mounting tube 2 and the threaded connecting tube 5 are connected and assembled, and prevent the internal optical lens from shifting due to the rotation of the lens barrel 1.
[0026] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, after the lens end cap 3 is connected and attached to the top of the lens barrel 1, the lens end cap 3 is respectively set inside the positioning tube 8 through the connecting post 7. While the positioning tube 8 protects the outside of the mounting tube 2, the lens end cap 3 can be assembled and disassembled by plugging. After the lens barrel 1 is fitted into the threaded connecting tube 5 through the mounting tube 2, the fixing ring 11 is screwed on. Under the action of the connecting ring 10 connected by the bearing, the fixing ring 11 can keep the limiting ring 9 stationary. The fixing ring 11 is screwed down to connect and fix the mounting tube 2 and the threaded connecting tube 5. At the same time as the fixing ring 11 is screwed on, the limiting protrusion 12 on the inner wall of the limiting ring 9 slides and engages with the limiting groove 13 on the outer wall of the mounting tube 2. This can further improve the stability of the assembly of the lens barrel 1 inside the mounting tube 2 while the mounting tube 2 and the threaded connecting tube 5 are connected and assembled.
[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
