Description

Technical Field

[0001] This utility model relates to the field of zoom lens mounting technology, and in particular to a zoom lens mounting structure that can prevent loosening. Background Technology

[0002] Currently, in fields such as security monitoring and industrial inspection, zoom lenses and camera bodies are mostly connected by threads or installed with simple clips.

[0003] While threaded connections are secure, installation and removal require multiple rotations, making the process cumbersome and time-consuming, and unsuitable for applications that frequently require lens changes. Existing snap-fit ​​connections, although improving installation and removal speed to some extent, typically have exposed locking mechanisms lacking effective protection against accidental contact. During use, lenses are highly susceptible to loosening or detachment due to accidental bumps or vibrations, posing a risk of lens damage from drops, indicating insufficient stability and reliability.

[0004] Therefore, there is an urgent need for a lens mounting structure that can achieve both quick assembly and disassembly, as well as good locking and anti-loosening functions. Utility Model Content

[0005] To overcome the aforementioned drawbacks, this utility model provides a zoom lens mounting structure that prevents loosening.

[0006] The technical solution is as follows: A zoom lens mounting structure with anti-loosening feature includes a housing, a base, a zoom lens, a support frame, a locking block, a first spring, a push block, a sliding sleeve, a third spring, and an anti-loosening component. The base is fixedly connected to the bottom of the housing, and the zoom lens is fixedly mounted on the top of the housing. Support frames are fixedly connected to the front, back, left, and right sides of the top of the housing. The bottom of the support frame is fixedly connected to the top of the base. Locking blocks are slidably connected to the support frames. The locking blocks are slidably connected to the housing and extend outwards through the outside of the housing. The bottom surface of the locking blocks is inclined. A first spring is connected between the inner side of the locking blocks and the support frame. A push block is fixedly connected to the top of the locking blocks. The push block is slidably connected to the housing and extends outwards through the outside of the housing. The outer surface of the push block is arc-shaped. A sliding sleeve is slidably connected to the top of the housing through multiple guide rods. The sliding sleeve is located outside the zoom lens. A third spring is sleeved on the outer side of the guide rods. The upper and lower ends of the third spring are connected to the top of the housing and the inner top surface of the sliding sleeve, respectively. The sliding sleeve is located above the push block, and the two form a contact engagement relationship. An anti-loosening component is provided on the sliding sleeve.

[0007] As an improvement to the above scheme, the angle between the bottom inclined surface of the card block and the horizontal plane is 30° to 60°.

[0008] As an improvement to the above solution, the anti-loosening component includes a sliding block, a fourth spring, and a limiting block. The sliding block is symmetrically slidably connected inside the sliding sleeve, and the top of the sliding block extends through the top surface of the sliding sleeve as the operating end. The fourth spring is connected between the sliding block and the inside of the sliding sleeve. The limiting block is fixedly connected to the lower side of the zoom lens below the sliding block, and the sliding block and the limiting block abut against each other.

[0009] As an improvement to the above scheme, the operating end of the sliding block is designed as a front and rear semi-circular structure.

[0010] As an improvement to the above solution, a second spring and a buffer pad are also included. The buffer pad is slidably connected to the middle of the bottom of the base, and the top of the buffer pad is connected to the inside of the base by a second spring.

[0011] As an improvement to the above solution, the cushioning pad is made of an elastic polymer material.

[0012] This utility model has the following advantages: 1. By cooperating with the inclined plate block and the first spring, it can be automatically locked by simply pressing down during installation, and can be released by pressing down the sliding sleeve with one hand during disassembly. This design abandons the traditional screw rotation or tool fastening method, which greatly improves the speed and convenience of installation and disassembly, and is especially suitable for application scenarios that require frequent lens replacement.

[0013] 2. The anti-loosening components (sliding block, fourth spring, and limit block) constitute a safety lock. After normal installation, the sliding sleeve is effectively locked and cannot be accidentally pressed down, thus completely avoiding the risk of the locking block loosening or the lens falling off due to accidental contact or vibration, ensuring the reliability and stability of the equipment in complex environments.

[0014] 3. The cushioning pad and second spring at the base can effectively absorb and buffer impacts and vibrations from the camera body or external sources. This structure not only enhances the physical connection between the lens and the camera interface, preventing loosening, but also provides a more stable working environment for the optical components, helping to reduce image shake and improve the clarity of the final image.

[0020] Example: A zoom lens mounting structure that prevents loosening, such as Figures 1-4 As shown, the device includes a housing 1, a base 2, a zoom lens 3, a support frame 4, a locking block 5, a first spring 6, a push block 7, a sliding sleeve 10, a third spring 11, and an anti-loosening component. The base 2 is fixedly connected to the bottom of the housing 1, and the zoom lens 3 is fixedly mounted on the top of the housing 1. The support frame 4 is fixedly connected to the front, back, left, and right sides of the top of the housing 1. The bottom of the support frame 4 is fixedly connected to the top of the base 2. Locking blocks 5 are slidably connected to the support frame 4. The locking blocks 5 are slidably connected to the housing 1 and extend outwards from the outside of the housing 1. The bottom surface of the locking block 5 is beveled. The first spring 6 connects the inner side of the locking block 5 to the support frame 4. A locking groove that mates with the locking block 5 is provided on the inner wall of the mounting slot of the camera that is compatible with this device. The locking block 5 contacts the mounting slot. The device enables quick installation of the zoom lens 3. The angle between the bottom inclined surface of the locking block 5 and the horizontal plane is 30° to 60°, ensuring that the locking block 5 can interact smoothly and with moderate resistance with the inner wall of the camera mounting slot during the pressing process. A push block 7 is fixedly connected to the top of the locking block 5. The push block 7 is slidably connected to the housing 1 and extends outward through the outside of the housing 1. The outer surface of the push block 7 is arc-shaped. A sliding sleeve 10 is slidably connected to the top of the housing 1 through multiple guide rods. The sliding sleeve 10 is located outside the zoom lens 3. A third spring 11 is sleeved on the outside of the guide rods. The upper and lower ends of the third spring 11 are connected to the top of the housing 1 and the inner top surface of the sliding sleeve 10, respectively. The sliding sleeve 10 is located above the push block 7, and the two form a contact engagement relationship. The sliding sleeve 10 is equipped with an anti-loosening component.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the anti-loosening component includes a sliding block 12, a fourth spring 13, and a limiting block 14. The sliding block 12 is symmetrically connected to the sliding sleeve 10. The top of the sliding block 12 extends through the top surface of the sliding sleeve 10 as the operating end. The operating end of the sliding block 12 is designed with a front and rear semi-circular structure to fit the curvature of the finger and facilitate the application of force. The fourth spring 13 is connected between the sliding block 12 and the inside of the sliding sleeve 10. The limiting block 14 is fixedly connected to the lower side of the zoom lens 3 below the sliding block 12. The sliding block 12 and the limiting block 14 abut against each other to limit the position of the sliding sleeve 10.

[0022] like Figure 2As shown, it also includes a second spring 8 and a buffer pad 9. The buffer pad 9 is slidably connected to the bottom center of the base 2. The second spring 8 is connected between the top of the buffer pad 9 and the inside of the base 2. The buffer pad 9 is made of an elastic polymer material, preferably rubber or polyurethane. It not only provides excellent cushioning and shock absorption performance, absorbing the impact during installation and the minor vibration during use, but also increases the static friction with the bottom of the camera mounting slot due to its high coefficient of friction, further helping to prevent the lens from loosening and improving the rigidity of the overall connection.

[0023] When this device is needed, first align the base 2 at the bottom of the device with the matching mounting slot on the camera. During this process, the buffer pad 9 at the bottom of the base 2 will first contact the bottom of the mounting slot. As the device continues to move downward, the buffer pad 9 is compressed, causing the second spring 8 at its top to gradually compress. This design can effectively improve the tightness between the base 2 and the bottom of the mounting slot, absorb and buffer the impact and vibration from the camera body or the outside, and avoid shaking and loosening during subsequent use. At the same time, the locking block 5 on the side of the housing 1 will contact the inner wall of the mounting slot. Under the action of the downward pushing force, the inclined surface of the locking block 5 is squeezed, forcing the locking block 5 to move inward. As the locking block 5 moves inward, it will compress the first spring 6. The push block 7 moves inward at the same time. When the device is pushed to the predetermined installation position, the locking block 5 is exactly aligned with the locking groove on the inner wall of the camera mounting slot. At this time, the compressed first spring 6 releases its elasticity instantly, pushing the locking block 5 and the push block 7 to reset. The locking block 5 moves outward and is firmly locked into the locking groove of the camera, thereby realizing the quick and stable installation between the zoom lens 3 and the camera.

[0024] When it is necessary to remove this device from the camera, the user must first use their fingers to simultaneously push the operating end of the sliding block 12 at the top of the sliding sleeve 10 inward and backward. The fourth spring 13 is then compressed, and the sliding block 12 moves backward and disengages from the limiting block 14, thereby releasing the lock on the sliding sleeve 10. Then, the user can press down on the sliding sleeve 10, which moves down and compresses the third spring 11. The bottom surface of the sliding sleeve 10 then contacts the exposed arc-shaped surface of the push block 7 and applies pressure. Since the push block 7 is fixedly connected to the locking block 5, this pressure is converted into an inward pushing force, which drives the locking block 5. Block 5 retracts inward, completely disengaging it from the camera's mounting slot. After block 5 disengages, the user can lift the entire device upward from the camera's mounting slot, completing a quick disassembly. After disassembly, first loosen the sliding sleeve 10, causing the compressed third spring 11 to rebound and push the sliding sleeve 10 upward to reset. Then, release the sliding block 12, causing the compressed fourth spring 13 to rebound and push the sliding block 12 forward to reset, so that its bottom re-abuts against the limiting block 14, locking the sliding sleeve 10 again to prevent accidental movement and ensuring stability after the next installation.
