Description

Technical Field

[0001] This invention belongs to the field of temporary storage technology for optical lenses, and in particular, a dustproof device for optical lenses. Background Technology

[0002] Optical lenses need to be temporarily stored inside a dustproof device during use to prevent them from being directly exposed to the external environment and contaminated by dust. After prolonged use, the sealing effect of the existing dustproof device's cover will weaken, allowing external dust and other debris to enter the dustproof device and contaminate the optical lenses, thus reducing the dustproof effect of the device.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN215324469U) for a temporary dustproof storage device for optical lenses. The device includes a box body, a filling sponge, and optical lenses. One side of the box body is connected to a lid via a hinge, and the two sides of the hinge are respectively fixed to the surfaces of the box body and the lid with second screws. The filling sponge is placed inside a storage space located on top of the lid. A fixing block is connected to the lid via a fixing hole. The optical lenses are placed in a compartment, with filling sponges placed at both ends of the circumference of the optical lenses. The compartment is located within a first shaped sponge installed inside the box body, and a second shaped sponge installed inside the lid. This temporary dustproof storage device for optical lenses uses environmentally friendly plastic for both the box body and lid, and the shaped sponge inside the box body effectively prevents dust from interfering with the temporarily stored optical lenses. However, this device does not consider that the sealing effect weakens after prolonged use, allowing external dust and other debris to enter and contaminate the optical lenses, reducing the device's dustproof effect. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof device for optical lenses 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 dustproof device, comprising:

[0006] A dustproof box for optical lenses, with a hollow top and a dust removal fan for optical lenses installed on the side of the dustproof box;

[0007] The shielding assembly includes a shielding plate and a rubber frame. The bottom surface of the shielding plate is connected to the rubber frame, and the bottom surface of the rubber frame is sealed against the top surface of the dustproof box. Two symmetrically arranged movable plates are connected to the side of the shielding plate. A plug-in rod is connected to the bottom surface of the movable plate. A fixed plate with a hollow top is slidably connected to the side of the plug-in rod. The adjacent sides of the two fixed plates are connected to the dustproof box. A fixing bolt is threadedly connected to the side of the fixed plate, and the threaded end of the fixing bolt abuts against the plug-in rod.

[0008] Preferably, the top surface of the shield is connected to an inverted U-shaped pull plate.

[0009] Preferably, a through groove is provided on the side of the dust box away from the fan, and a filter assembly is provided on the inner wall of the through groove of the dust box.

[0010] Preferably, the filter assembly includes a filter frame and a filter screen, and the inner wall of the groove of the dustproof box is slidably connected to the filter frame.

[0011] Preferably, the inner wall of the filter frame is connected to the filter screen, and C-shaped connecting plates are connected to both ends of the side of the filter frame.

[0012] Preferably, a fixed bearing is provided on the inner side of the connecting plate, and the outer rings of the two fixed bearings are embedded and fixedly connected to the side of the filter frame.

[0013] Preferably, the inner ring of the fixed bearing is interference-fitted with a rotating block, and the two end faces of the rotating block are connected to limit plates.

[0014] Preferably, the adjacent sides of the two limiting plates are in sliding frictional contact with the filter frame and the inner wall of the dust box.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This optical lens dustproof device places the optical lens inside a dustproof box and seals the dustproof box with a shielding component to protect the optical lens from dust. When the sealing cover is rotated by a hinge to shield the dustproof box, the sealing rubber frame is subjected to pressure for a long time and undergoes plastic deformation, causing external dust and other debris to flow into the dustproof box through the gaps, reducing the dustproof effect of the device on the optical lens. The plug rod moves down along the inner cavity of the fixed plate. With the connection of the moving plate, the shielding plate drives the rubber frame to come into tight contact with the dustproof box during the transmission process, thereby sealing the contact. The fixing bolt fixes the relative position of the fixed plate and the plug rod, thereby enhancing the dustproof effect of the dustproof device on the optical lens.

[0017] This optical lens dustproof device addresses the issue of external dust and debris flowing into the dustproof box when optical lenses are removed or stored, thus reducing the device's dustproof effect. A fan provides power to extract the dust from the dustproof box and direct it to the outside, preventing dust from contaminating the optical lenses and improving the device's dustproof performance. A filter assembly filters the incoming air to prevent secondary contamination of the optical lenses. The rotation of two rotating blocks releases the four limiting plates from the inner wall of the dustproof box, and pulling the connecting plate detaches the filter assembly from the dustproof box, facilitating filter removal and cleaning, thus improving the device's ease of use.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] To address the issue of weakened sealing and reduced dust protection for optical lenses after prolonged use, please refer to [link to relevant documentation]. Figures 1 to 6 The structure of the device body includes:

[0031] An optical lens dustproof box 1 has a hollow top and an optical lens dust removal fan 2 is installed on the side of the dustproof box 1.

[0032] The shielding assembly 3 includes a shielding plate 4 and a rubber frame 5. The bottom surface of the shielding plate 4 is connected to the rubber frame 5, and the bottom surface of the rubber frame 5 is sealed and abutted against the top surface of the dustproof box 1. Two symmetrically arranged movable plates 6 are connected to the side of the shielding plate 4. The bottom surface of the movable plate 6 is connected to a plug rod 7. The side of the plug rod 7 is slidably connected to a fixed plate 8 with a hollow top. The adjacent sides of the two fixed plates 8 are connected to the dustproof box 1. The side of the fixed plate 8 is threadedly connected to a fixing bolt 9, and the threaded end face of the fixing bolt 9 abuts against the plug rod 7.

[0033] In this embodiment, the shielding component 3 provides shielding for the dustproof box 1. Existing dustproof devices typically use hinges to shield the dustproof box 1. The rubber frame 5, which provides the sealing effect, is prone to plastic deformation during use, resulting in a weakened sealing effect. The top surface of the fixing plate 8 has a groove, and the groove of the fixing plate 8 is slidably connected to the insertion rod 7, allowing the insertion rod 7 to move vertically along the inner cavity of the fixing plate 8. Under the connection of the moving plate 6, the shielding plate 4 moves the rubber frame 5 downward, so that the bottom surface of the rubber frame 5 is tightly pressed against the top surface of the dustproof box 1. The vertical position of the shielding plate 4 is adjusted to improve the sealing effect of the shielding assembly 3 on the dustproof box 1, preventing external dust from flowing in and contaminating the optical lens, thereby improving the dustproof effect of the device on the optical lens. The fixing bolt 9 rotates and moves along the thread path of the fixing plate 8, so that the thread end face of the fixing bolt 9 is in close contact with the plug rod 7, thereby fixing the relative position of the plug rod 7 and the fixing plate 8. During the transmission process, the shielding plate 4 and the rubber frame 5 are prevented from shaking or shifting, thus improving the structural stability of the device components.

[0034] Specifically, the top surface of the baffle plate 4 is connected to an inverted U-shaped pull plate 10, and a through groove is provided on the side of the dust box 1 away from the fan 2. A filter assembly 11 is provided on the inner wall of the through groove of the dust box 1.

[0035] In this embodiment, after removing the two fixing bolts 9, it is easy to manually pull the pull plate 10 to disassemble the shield 4 and the rubber frame 5, thereby removing the seal of the shield 4 and the rubber frame 5 on the dustproof box 1, making it easier to take out or store optical lenses inside the dustproof box 1. During this process, external dust can easily flow into the dustproof box 1, causing contamination of the optical lenses. The fan 2 provides power so that the input end of the fan 2 draws out the dust inside the dustproof box 1 and discharges it through the output end of the fan 2, thereby cleaning the dust that has flowed into the dustproof box 1 and improving the dustproof effect of the device on the optical lenses. The filter component 11 provides a filtering function to prevent external dust from entering the dustproof box 1 and causing secondary contamination of the optical lenses. The side of the dustproof box 1 is embedded in the fixing end of the fan 2 by bolts.

[0036] Specifically, the filter assembly 11 includes a filter frame 12 and a filter screen 13. The inner wall of the groove of the dust box 1 is slidably connected to the filter frame 12. The inner wall of the filter frame 12 is connected to the filter screen 13. C-shaped connecting plates 14 are connected to both ends of the side of the filter frame 12. Fixed bearings 15 are provided on the inner side of the connecting plates 14. The outer rings of the two fixed bearings 15 are embedded and fixedly connected to the side of the filter frame 12. Rotating blocks 16 are interference-fitted to the inner rings of the fixed bearings 15. Limiting plates 17 are connected to both ends of the rotating blocks 16. The adjacent sides of the two limiting plates 17 are in sliding friction contact with the filter frame 12 and the inner wall of the dust box 1.

[0037] In this embodiment, the filter frame 12 provides support for the filter screen 13, enabling the filter screen 13 to filter the air introduced into the dustproof box 1. When the filter frame 12 extends into the inner wall of the groove of the dustproof box 1, the two sides of the filter frame 12 are flush with the inner and outer side walls of the dustproof box 1, respectively. When the two rotating blocks 16 rotate, the two limiting plates 17 rotate around the rotating blocks 16 as the axis, moving the two limiting plates 17 to the position of contact with the side wall of the dustproof box 1, thereby realizing the installation and fixation of the filter assembly 11, and realizing the filtering effect of the air entering the dustproof box 1. Under the power provided by the fan 2, the dust flowing into the dustproof box 1 is discharged, thereby improving the dustproof effect of the dustproof device on the optical lens. When the four limiting plates 17 are removed from the dustproof box 1, the filter assembly 11 can be easily disassembled, thereby facilitating the cleaning of the dust adhering to the surface of the filter screen 13.

[0038] The fan 2 is existing technology, and its working principle, size and model are irrelevant to the function of this application, so it will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0039] Working principle

[0040] When using this optical lens dustproof device, the user extends the two plug rods 7 into the inner cavity of the fixing plate 8, and moves the plug rods 7 vertically along the inner cavity of the fixing plate 8. With the connection of the two moving plates 6, the shielding plate 4 drives the rubber frame 5 to block the top of the dustproof box 1. At the same time, it is convenient to adjust the contact tightness between the rubber frame 5 and the dustproof box 1. The fixing bolt 9 fixes the relative position of the plug rods 7 and the fixing plate 8. By removing the shielding plate 4 and the rubber frame 5 from the dustproof box 1, the optical lens can be stored and taken out inside the dustproof box 1.

[0041] During the storage and retrieval of optical lenses, dust is very likely to flow into the dustproof box 1. The fan 2 is started to extract the dust inside the dustproof box 1. The air introduced into the dustproof box 1 from the outside is filtered through the filter assembly 11, causing the two rotating blocks 16 to rotate and the two limiting plates 17 to rotate around one of the rotating blocks 16 as the axis. During the transmission process, the contact between the four limiting plates 17 and the dustproof box 1 is released, and the filter assembly 11 is disassembled and cleaned.
