Description

Technical Field

[0001] This utility model relates to the field of optical equipment technology, and in particular to an optical lens anti-detachment mounting structure. Background Technology

[0002] Optical lenses are indispensable key components in optical systems, widely used in microscopes, telescopes, camera lenses, lasers, and other equipment. Their main function is to achieve imaging, focusing, or beam shaping by refracting or reflecting light. The mounting structure of the lens plays a crucial role in optical equipment. A well-designed mounting structure can not only ensure the precise alignment and fixation of the lens, but also effectively prevent the lens from shifting or falling off due to vibration, impact, or other external forces.

[0003] Traditional lens mounting methods mainly include threaded connections, adhesive bonding, and snap-on fastening. However, these traditional methods have the following shortcomings:

[0004] 1. Traditional snap-on and adhesive connections are prone to loosening or falling off after long-term use or when subjected to vibration or impact, causing the lens to shift and affecting image quality.

[0005] 2. Many existing structures require specialized tools for installation and disassembly, which is complex, time-consuming, and increases maintenance costs and the learning curve for users.

[0006] 3. Some snap-on fixing structures lack an effective buffer mechanism, and cannot effectively protect the lens when encountering external impacts, which can easily cause damage. Utility Model Content

[0007] To overcome the aforementioned shortcomings, the technical problem of this utility model is to provide an optical lens anti-drop mounting structure.

[0008] The technical implementation scheme of this utility model is as follows: an optical lens anti-drop installation structure, including a lens body, a connecting ring, a fixing ring, a sliding block, a locking block, and a return spring. The lens body is installed on the connecting ring. An annular groove is provided on the outer side of the connecting ring. The connecting ring is locked onto the fixing ring through the groove. Sliding blocks are slidably connected to both sides of the fixing ring. Locking blocks are connected to the inner side of each sliding block. Two return springs are connected between the locking blocks and the inner side of each sliding block. The two locking blocks are locked onto the groove of the connecting ring.

[0009] Optionally, the left side wall of the card block is beveled.

[0010] Optionally, it also includes a threaded sleeve and a rotating disk, with the threaded sleeve connected to the outer surface of the fixed ring, the threaded sleeve passing through the sliding block, and the rotating disk connected to the outer side of the threaded sleeve through its inner thread.

[0011] Optionally, anti-slip grooves are provided at intervals on the outer surface of the rotating disk.

[0012] Optionally, it also includes a first buffer pad, with an annular first buffer pad connected to the left side of the inside of the rotating disk. After the rotating disk is fixed to the outside of the fixed ring, the first buffer pad abuts against the connection between the rotating disk and the fixed ring.

[0013] Optionally, it also includes a support block, compression springs, and a second buffer pad. The annular support block is snapped and fixed to the right side of the fixing ring. Multiple compression springs are connected at annular intervals along the left side wall of the support block, and an annular second buffer pad is connected between the left ends of the compression springs.

[0014] The beneficial effects are: 1. Through the precise fit between the locking block and the groove of the connecting ring, combined with the automatic reset mechanism of the return spring, this device ensures the stability of the lens body after installation. The combination of the rotating disk and the threaded sleeve further restricts the position of the sliding block and the locking block, strengthens the overall structure, and effectively prevents the lens from falling off due to vibration or external force.

[0015] 2. The inclined design of the locking block makes the installation process extremely simple. Users only need to push the connecting ring into the fixing ring, and the locking block will automatically lock. No additional tools are required. When disassembling, users only need to rotate to remove the rotating disk and pull the sliding block to easily remove the lens body. This design simplifies the maintenance and replacement process, greatly improves operating efficiency, and reduces the difficulty of use for users.

[0016] 3. The support block, compression spring, and second buffer pad provide additional radial support to the connecting ring, significantly improving the overall stability and impact resistance of the device. In particular, when disassembling the lens body, the elasticity of the compression spring can automatically push the lens body out, which not only facilitates disassembly but also reduces the force required for manual operation and protects the safety of the components.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: An optical lens anti-drop mounting structure, such as... Figures 1-3 As shown, the device includes a lens body 1, a connecting ring 2, a fixing ring 3, a sliding block 4, a locking block 5, and a return spring 6. The lens body 1 is mounted on the connecting ring 2. The outer side of the connecting ring 2 has an annular groove. The connecting ring 2 is locked onto the fixing ring 3 through the groove. The fixing ring 3 has sliding blocks 4 slidably connected to both the front and rear sides. The inner side of each sliding block 4 is welded with a locking block 5. Two return springs 6 are connected between the locking block 5 and the inner side of the sliding block 4. The two locking blocks 5 engage with the groove of the connecting ring 2 to fix the connecting ring 2. The left side wall of the locking block 5 is inclined. When the connecting ring 2 is pushed into the fixing ring 3 from left to right, the locking block 5 automatically engages with the groove through the inclined surface.

[0024] like Figures 1-2 As shown, it also includes a threaded sleeve 7, a rotating disk 8, and a first buffer pad 9. The threaded sleeve 7 is connected to the outer surface of the fixing ring 3. The threaded sleeve 7 passes through the sliding block 4, leaving an area for the sliding block 4 to slide. The rotating disk 8 is connected to the outer side of the threaded sleeve 7 through its inner thread to abut against the sliding block 4 and ensure that the sliding block 4 cannot move. Anti-slip grooves are provided at intervals on the outer surface of the rotating disk 8 to provide a certain friction force when rotating the rotating disk 8, which is conducive to operation. The inner left side of the rotating disk 8 is connected to an annular first buffer pad 9. After the rotating disk 8 is fixed to the outer side of the fixing ring 3, the first buffer pad 9 abuts against the connection between the rotating disk 8 and the fixing ring 3 to ensure the tightness between the two.

[0025] like Figure 2 and Figure 4As shown, it also includes a support block 10, a compression spring 11, and a second buffer pad 12. The annular support block 10 is snapped and fixed to the right side of the fixing ring 3, and the two are tightly snapped together. Multiple compression springs 11 are welded along the annular interval on the left side wall of the support block 10. An annular second buffer pad 12 is welded between the left ends of the compression springs 11. After the connecting ring 2 is installed inside the fixing ring 3, the second buffer pad 12 is in close contact with the connecting ring 2, and the compression springs 11 will be in a compressed state.

[0026] When it is necessary to install the lens body 1, first assemble the lens body 1 onto the connecting ring 2, and then tightly embed the support block 10 into the right side of the fixing ring 3. At this time, the second buffer pad 12 is located in the inner ring position of the fixing ring 3. Next, the user needs to push the connecting ring 2 into the fixing ring 3 from the left. During this process, the connecting ring 2 will first contact the inclined surface of the locking block 5, forcing the locking block 5 and the sliding block 4 to move outward. At the same time, the return spring 6 is compressed. Meanwhile, the right side of the connecting ring 2 begins to squeeze the second buffer pad 12, causing the compression spring 11 to gradually contract. Once the groove on the connecting ring 2 is aligned with the locking block 5, the return spring 6 releases energy, pushing the locking block 5 and the sliding block 4 to move inward and reset. The locking block 5 then engages with the groove, thereby fixing the connecting ring 2. To further reinforce the lens body 1, the user can rotate the rotating disk 8 so that it fits on the outside of the fixing ring 3. The internal thread on the inner side of the rotating disk 8 engages with the threaded sleeve 7 so that the rotating disk 8 firmly wraps around the fixing ring 3, thereby resisting the sliding block 4 and preventing the sliding block 4 from moving, ensuring the stability of the locking block 5. In addition, the first buffer pad 9 inside the rotating disk 8 will tightly fit against the left side of the fixing ring 3, ensuring the connection strength and sealing performance between the two. This completes the fixing of the lens body 1. The structure can then be installed on the equipment for use.

[0027] When it is necessary to disassemble or replace the lens body 1, the user only needs to rotate the rotating disk 8 counterclockwise to remove it, thereby releasing the restriction on the sliding block 4. Then, the user can manually pull the sliding block 4, causing the locking block 5 to move outward. The return spring 6 is compressed accordingly, and the locking block 5 moves outward to disengage from the groove of the connecting ring 2. At this time, the compression spring 11 returns to its original state, pushing the second buffer pad 12 to rebound to the left, thereby pushing out the connecting ring 2 along with the lens body 1 for quick disassembly. After releasing the sliding block 4, the return spring 6 will drive the sliding block 4 and the locking block 5 to reset and return to the initial position, ready for the next installation operation.
