Optical lens sealing structure

Abstract

This utility model relates to the field of optical lens technology and discloses an optical lens sealing structure, including a lens barrel, a pressure cap, and a rubber ring for sealing. The outer wall of the lens barrel has an annular mounting groove, and a filter is fixedly installed on the inner wall of the pressure cap. The pressure cap is provided with a control component and a driven component. The control component includes a support block. In this optical lens sealing structure, by providing the control component, a moving plate is pushed at the bottom of the pressure cap. The moving plate is forced to drive the fixed block to slide within the pressure cap. When the fixed block moves, it can compress the spring. When the fixed block moves, the locking block connected to the fixed block by the flat rod can be removed from the locking hole opened in the support block, thereby releasing the restriction on the support block and the rubber ring. This makes it easier for the operator to replace the worn rubber ring and avoids the sealing performance between the lens barrel and the pressure cap due to the difficulty in replacing the damaged rubber ring.

Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, specifically to an optical lens sealing structure. Background Technology

[0002] Digital cameras, digital camcorders, mobile phones with video recording capabilities, and laptops with webcams are typically equipped with lenses. A lens consists of an optical lens assembly and an image sensor assembly located at the rear of the optical lens assembly. Existing optical lenses, while reducing weight and saving costs, cannot simultaneously ensure lens sealing and thus cannot guarantee lens quality.

[0003] According to a published optical lens sealing structure (publication number: CN210157275U), the above application uses waterproof cotton to enhance the sealing between the cap and the lens barrel. However, the waterproof cotton inside the cap may be damaged due to wear after a long time, resulting in poor sealing. The waterproof cotton is usually glued to the inside of the cap, which is very inconvenient to replace. In order to solve this problem, we propose an optical lens sealing structure. Utility Model Content

[0004] The purpose of this invention is to provide an optical lens sealing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optical lens sealing structure, comprising a lens barrel, a pressure cap, and a rubber ring for sealing. The outer wall of the lens barrel has an annular mounting groove. A filter is fixedly mounted on the inner wall of the pressure cap. A control component and a driven component are disposed within the pressure cap. The control component includes:

[0006] A support block is fixedly installed on the side of a rubber ring, and a locking hole is provided inside the support block;

[0007] The fixing block has its inner wall fitted to the cut surface of the clamping block. The side of the clamping block and the inside of the pressure cap are provided with fixing parts to fix the rubber ring, thereby releasing the restriction on the support block and the rubber ring, so that the operator can replace the worn rubber ring and avoid the sealing between the lens barrel and the pressure cap due to the difficulty in replacing the damaged rubber ring.

[0008] Preferably, the fixing component includes a flat rod, which is fixedly installed on the inner wall of the fixing block. The flat rod passes through the locking block and is slidably connected to the locking block. The flat rod ensures the stability of the locking block during lateral movement.

[0009] Preferably, the side of the locking block is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the outer wall of the flat rod. When the cut surface of the locking block is no longer in contact, it can spring up from the surface of the flat rod under the action of the spring.

[0010] Preferably, the side of the fixing block is fixedly connected to one end of the second spring, the other end of the second spring is fixedly installed on the inner wall of the pressure cover, and a movable plate is fixedly installed at the bottom of the fixing block. When the fixing block is no longer under force, it can spring up from inside the pressure cover under the action of the second spring.

[0011] Preferably, the driven component includes a pressure rod that passes through the movable plate and is slidably connected to the movable plate. A round rod is fixedly installed on the inner wall of the movable plate. When the pressure rod moves within the movable plate, the round rod fixed at the bottom of the pressure rod can move synchronously.

[0012] Preferably, the side of the pressure rod is fixedly connected to one end of the spring three, and the other end of the spring three is fixedly installed on the inner wall of the moving plate. When the pressure rod is no longer compressed, it can spring up from inside the moving plate under the action of the spring three.

[0013] Preferably, the bottom of the pressure cap has a vertical hole and a horizontal hole. When the round rod is located in the horizontal hole, the lateral movement of the moving plate and the fixed block can be restricted.

[0014] Compared with the prior art, the present invention provides an optical lens sealing structure, which has the following beneficial effects:

[0015] 1. This optical lens sealing structure, through the setting of a control component, pushes a moving plate at the bottom of the pressure cover. The moving plate, under force, causes the fixed block to slide inside the pressure cover. When the fixed block moves, it can compress the spring. When the fixed block moves, the locking block connected to the flat rod inside the fixed block can be removed from the locking hole opened in the support block, thereby releasing the restriction on the support block and the rubber ring. This makes it easier for the operator to replace the worn rubber ring and avoids the difficulty in replacing the rubber ring due to damage, which affects the sealing between the lens barrel and the pressure cover.

[0016] 2. The optical lens sealing structure is equipped with a driven component. When the moving plate moves, the locking block can be moved out of the locking hole. Therefore, when the round rod is located in the horizontal hole, the moving plate cannot slide, thereby restricting the movement of the locking block and ensuring the stability of the rubber ring after installation.

[0025] like Figures 1-7 As shown, this utility model provides a technical solution: an optical lens sealing structure, including a lens barrel 1, a pressure cap 3, and a rubber ring 5 for sealing. An annular mounting groove 2 is formed on the outer wall of the lens barrel 1. A filter 4 is fixedly installed on the inner wall of the pressure cap 3. A control component 6 and a driven component 7 are provided inside the pressure cap 3. The control component 6 includes: a support block 60, a locking hole 61, a locking block 62, a fixing block 63, and a fixing member 64. The support block 60 is fixedly installed on the side of the rubber ring 5, and a locking hole 61 is formed inside the support block 60. The inner wall of the fixing block 63 fits against the cut surface of the locking block 62, and the side of the locking block 62 and the pressure cap 5 are sealed together. The cover 3 is equipped with a fixing member 64 for fixing the rubber ring 5. When the moving plate 644 is pushed laterally, the fixing block 63 fixed on the surface of the moving plate 644 can move synchronously and be squeezed by the spring 643. When the fixing block 63 moves, the locking block 62 connected to the flat rod 641 in the fixing block 63 can be removed from the locking hole 61 in the support block 60, thereby releasing the restriction on the support block 60 and the rubber ring 5, so that the operator can replace the worn rubber ring 5 and avoid the sealing between the lens barrel 1 and the cover 3 due to the difficulty in replacing the damaged rubber ring 5.

[0026] The fixing component 64 includes a flat rod 641, which is fixedly installed on the inner wall of the fixing block 63. The flat rod 641 passes through the locking block 62 and is slidably connected to the locking block 62. The flat rod 641 ensures the stability of the locking block 62 during lateral movement. The side of the locking block 62 is fixedly connected to one end of the first spring 642, and the other end of the first spring 642 is fixedly installed on the outer wall of the flat rod 641. When the cut surface of the locking block 62 is no longer in contact, it can spring up from the surface of the flat rod 641 under the action of the first spring 642. The side of the fixing block 63 is fixedly connected to one end of the second spring 643, and the other end of the second spring 643 is fixedly installed on the inner wall of the pressure cover 3. A movable plate 644 is fixedly installed at the bottom of the fixing block 63. When the fixing block 63 is no longer under force, it can spring up from inside the pressure cover 3 under the action of the second spring 643. The driven component 7 includes a pressure rod 71, which passes through and is slidably connected to the movable plate 644. A round rod 72 is fixedly installed on the inner wall of the movable plate 644. When the pressure rod 71 moves within the movable plate 644, the round rod 72 fixed to the bottom of the pressure rod 71 moves synchronously. The side of the pressure rod 71 is fixedly connected to one end of a spring 73, and the other end of the spring 73 is fixedly installed on the inner wall of the movable plate 644. When the pressure rod 71 is no longer compressed, it can spring out from within the movable plate 644 under the action of the spring 73. A vertical hole 74 and a horizontal hole 75 are provided at the bottom of the pressure cover 3. When the round rod 72 is located within the horizontal hole 75, the lateral movement of the movable plate 644 and the fixed block 63 can be restricted.

[0027] In this invention, during use, the rubber ring 5 and the support block 60 are inserted into the bottom of the pressure cap 3. When the support block 60 enters the pressure cap 3, it will abut against the cut surface of the locking block 62. When the cut surface of the support block 60 is abutted, it can slide along the surface of the flat rod 641 under the action of the spring 642. When the locking block 62 touches the locking hole 61 opened on the surface of the support block 60, the locking block 62 will spring up under the action of the spring 642 and lock into the locking block 62, thereby completing the installation of the support block 60 and the rubber ring 5. After installation, the pressure cap 3 is inserted into the annular mounting groove 2 inside the lens barrel 1. The rubber ring 5 inside the pressure cap 3 seals the space between the lens barrel 1 and the pressure cap 3. When the rubber ring 5 wears down over a long period of time and the sealing performance becomes poor, it needs to be replaced. When the pressure rod 71 is pressed, it compresses the spring 73. When the pressure rod 71 moves, the round rod 72 fixed on the surface of the pressure rod 71 will move out of the horizontal hole 75 and into the vertical hole 74. After moving, the pressing force is maintained, and the moving plate 644 is pushed horizontally. When the moving plate 644 moves, the fixing block 63 fixed on the surface of the moving plate 644 can move synchronously and be compressed by the spring 643. When the fixing block 63 moves, the locking block 62 connected to the flat rod 641 in the fixing block 63 can be removed from the locking hole 61 in the support block 60, thereby releasing the restriction on the support block 60 and the rubber ring 5. This makes it easier for the operator to replace the worn rubber ring 5 and avoid the sealing between the lens barrel 1 and the pressure cap 3 due to the difficulty in replacing the damaged rubber ring 5.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
