[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] Reference Figures 1-3 This utility model provides an embodiment of an anti-oxidation optical lens vacuum packaging machine sealing chamber, comprising a sealing chamber body 1 and an observation window 2. The observation window 2 is fixedly connected to the inner front wall of the sealing chamber body 1. The observation window 2 allows the operator to observe the packaging status, vacuuming, and sealing process of the optical lenses inside the sealing chamber body 1 in real time, ensuring the normal progress of the packaging process and avoiding packaging failure or lens damage due to lack of observation. The top outer wall of the sealing chamber body 1 has a placement opening 3. The sealing chamber body 1 is provided with a sealing structure 4, and the sealing structure 4 is provided with an auxiliary structure 5. The sealing structure 4 includes an L-shaped frame 41, which is snapped into the top inner wall of the sealing chamber body 1. An anti-detachment rope 4 is fixedly connected to the top outer wall of the L-shaped frame 41. 2. The anti-detachment rope 42 is used to suspend the sealing cover 44. When the sealing cover 44 is open, it can prevent it from contacting the ground or other objects and causing pollution. It also prevents other impurities from entering the sealed chamber body 1 when the sealing cover 44 is closed, ensuring cleanliness inside the chamber and improving sealing quality. The top inner wall of the placement port 3 is provided with a threaded groove 43. The inner side wall of the threaded groove 43 is threadedly connected to the sealing cover 44. The bottom outer wall of the sealing cover 44 is provided with a positioning port 45. The bottom inner wall of the positioning port 45 is slidably connected to a positioning ring 46. The outer side wall of the positioning ring 46 is fixedly connected to a silicone rubber ring 47. The silicone rubber ring 47 has good sealing performance. When it is attached to the inner side wall of the placement port 3, it can effectively prevent outside air from entering the sealed chamber body 1 and prevent the optical lens from oxidizing.
[0024] Reference Figures 2-4 The outer side wall of the positioning ring 46 is slidably connected to the bottom outer wall of the sealing cover 44. The silicone rubber ring 47 is slidably connected to the inner side wall of the placement port 3. An adjusting plate 48 is slidably connected to the bottom inner wall of the sealing cover 44. The adjusting plate 48 slides on the bottom inner wall of the sealing cover 44. The position of the insertion rod 49 can be controlled by moving the adjusting plate 48, thereby realizing the fixing and disassembly of the positioning ring 46, which facilitates the maintenance of the sealing components. The insertion rod 49 is fixedly connected to the left outer wall of the adjusting plate 48, and the right outer wall of the adjusting plate 48 is fixedly connected to the insertion rod 49. A compression spring 410 is fixedly connected. A limiting hole 411 is opened on the inner side wall of the positioning ring 46. The limiting hole 411 cooperates with the insertion rod 49 to limit the position of the positioning ring 46, so that the positioning ring 46 remains stable on the sealing cover 44 and ensures the sealing effect of the silicone rubber ring 47. The sealing cover 44 is hinged to the top of the anti-detachment rope 42. The hinge between the sealing cover 44 and the anti-detachment rope 42 allows the sealing cover 44 to rotate around the hinge point, which is convenient for opening and closing. At the same time, the anti-detachment rope 42 can prevent the sealing cover 44 from falling off accidentally.
[0025] Reference Figures 3-4The auxiliary structure 5 includes a limiting port 51, which is located on the right inner wall of the L-shaped frame 41. An L-shaped groove 52 is provided on the top inner wall of the sealing chamber body 1. The L-shaped groove 52 cooperates with the L-shaped frame 41, providing guidance and positioning for the installation and disassembly of the L-shaped frame 41, enabling accurate installation of the L-shaped frame 41 on the sealing chamber body 1. This also facilitates maintenance and replacement of the sealing structure 4. A lever 53 is slidably connected to the left inner wall of the sealing chamber body 1. The lever 53 slides on the left inner wall of the sealing chamber body 1. Operators can control the movement of the insert plate 54 by pulling the lever 53, thereby achieving the installation and disassembly of the L-shaped frame 41. The operation is convenient. The rear outer wall of the lever 53 is fixedly connected... The device is equipped with an insert plate 54. A telescopic spring 55 is fixedly connected to the front outer wall of the lever 53. Silicone pads are fixedly connected to the left and right outer walls of the lever 53. The silicone pads can increase the friction when the operator pulls the lever 53 to prevent the hand from slipping. At the same time, they play a certain cushioning role to protect the operator's hands. The insert plate 54 passes through the right inner wall of the limiting port 51. A wear-resistant pad is fixedly connected to the side outer wall of the insert plate 54. The wear-resistant pad can reduce the frictional wear between the insert plate 54 and the inner wall of the limiting port 51, extend the service life of the insert plate 54 and the limiting port 51, and ensure the long-term stable operation of the auxiliary structure 5. The end of the telescopic spring 55 away from the lever 53 is fixedly connected to the inner wall of one side of the sealed chamber body 1.
[0026] Working principle: The optical lens is placed into the sealed chamber body 1 through the placement port 3, while the sealing cover 44 is suspended by the anti-detachment rope 42 to prevent the sealing cover 44 from contacting the ground or other objects and causing contamination. This also prevents other impurities from entering the sealed chamber body 1 when the sealing cover 44 is closed. The sealing cover 44 is then rotated into the threaded groove 43 of the placement port 3, allowing the silicone rubber ring 47 to adhere to the inner side wall of the placement port 3 for sealing. Then, the existing air pump is connected to the air extraction valve to extract air from the sealed chamber body 1, and then the air extraction valve is closed. The sealed chamber body 1 is then transported by hand using the anti-detachment rope 42 to prevent direct placement and collision with other objects during transport, which could cause damage and leakage. The silicone rubber ring 47 is made of fluororubber. Its temperature resistance range is 20℃~200℃, its aging resistance is improved by 3 times and its service life is extended to 2-3 years. The gas permeability is reduced by 50%, improving the sealing performance. In addition, during long-term use, by opening the sealing cover 44 and then pulling the two adjusting plates 48, the insertion rod 49 is moved. The insertion rod 49 moves and separates from the limiting hole 411. Then, the positioning ring 46 is separated from the positioning port 45. When the positioning ring 46 is separated, the silicone rubber ring 47 is also disassembled. Only the silicone rubber ring 47 needs to be replaced separately, saving the overall replacement cost. At the same time, when the sealing cover 44 or the anti-detachment rope 42 in the sealing structure 4 ages, the insertion plate 54 is moved by pulling the lever 53. The insertion plate 54 moves and separates from the limiting port 51. Then, the L-shaped frame 41 is pulled out from the L-shaped groove 52 for convenient disassembly and maintenance of the sealing structure 4.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
