Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical lens technology, specifically relating to a dustproof and waterproof optical lens storage box. Background Technology
[0002] Current lens packaging typically consists of a plastic box with a vacuum-sealed bag. This method is cost-effective for new lenses, but once the lenses are used, the vacuum packaging is no longer available. For long-term storage, the lenses must be placed in a desiccant cabinet. Without a desiccant cabinet or when it's not possible to use one, lenses, especially metal optical lenses, are highly susceptible to oxidation and corrosion from oxygen and water vapor in the air. Utility Model Content
[0003] In view of this, in order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a dustproof and waterproof optical lens storage box that can provide a clean and dry environment for optical lenses, making it convenient and easy to store optical lenses for a long time.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A dustproof and waterproof optical lens storage case includes a detachably connected body and a lid. A sealing strip is provided between the top surface of the body and the bottom surface of the lid. A humidity monitoring component is provided on the lid. The interior of the body has a cavity for accommodating the optical lens. A partition component is also provided inside the body to divide the cavity into a first cavity and a second cavity. The partition component has an air passage connecting the first and second cavities. The air passage is configured to allow gas passage while blocking solid passage. The sealing strip between the top surface of the body and the bottom surface of the lid ensures the airtightness of the cavity, which helps to keep the interior of the case dry.
[0006] According to some preferred embodiments of the present invention, the partition assembly includes a fixing plate, the fixing plate being detachably connected to the box body and the outer peripheral edge of the fixing plate being in contact with the inner wall of the box body, the first cavity being located below the fixing plate, and the second cavity being located above the fixing plate.
[0007] According to some preferred embodiments of the present invention, the optical lens is located in a first cavity, and a desiccant is placed in a second cavity.
[0008] According to some preferred embodiments of the present invention, the fixing plate is provided with a plurality of through holes spaced apart in its thickness direction, and the top surface of each through hole is covered with a filter screen.
[0009] According to some preferred embodiments of this utility model, the air passage is formed by through holes and corresponding filters, with each through hole located within the orthographic projection of a corresponding filter on the fixed plate. The filter ensures that only gas can pass between the first and second cavities, while preventing dust particles from passing through. This keeps the lower first cavity, where the optical lens is placed, dry and dust-free, thus protecting the optical lens from moisture corrosion and dust contamination.
[0010] According to some preferred embodiments of this invention, the thickness of the first cavity is greater than the thickness of the optical lens. This ensures that the optical lens located in the first cavity is not compressed.
[0011] According to some preferred embodiments of the present invention, a plurality of optical lenses are placed in the first cavity, and the plurality of optical lenses are simultaneously detachably connected to the bottom surface of the fixing plate or the bottom surface of the inner wall of the box, with adjacent optical lenses spaced apart.
[0012] According to some preferred embodiments of this utility model, a handle is fixedly provided on the side of the fixing plate near the box cover. The handle facilitates the removal of the fixing plate from the receiving cavity when disassembling the fixing plate.
[0013] According to some preferred embodiments of the present invention, the humidity monitoring component includes an installation part and a humidity test strip. The installation part extends through the thickness direction of the box cover and is fixedly connected to the box cover. The installation part has a through cavity extending through its length direction inside, and the through cavity communicates with a second cavity.
[0014] According to some preferred embodiments of this utility model, the humidity test paper is disposed at the top of the cavity and above the lid. A transparent cover is also fixedly disposed at the top of the cavity, located on the side of the humidity test paper away from the lid. The humidity test paper communicates with the second cavity and is also connected to the first cavity through an air passage. The transparent cover ensures complete isolation of the humidity test paper from the outside, allowing for a more accurate reflection of the humidity level within the cavity. The transparent cover facilitates observation of the humidity test paper's condition, thus enabling a more intuitive determination of whether the inside of the box is dry. Furthermore, since a desiccant is placed in the second cavity, it reduces the humidity inside the box. If the desiccant becomes ineffective, the humidity inside the box will increase. When the humidity test paper changes color, the desiccant needs to be replaced, along with a new humidity test paper.
[0015] By adopting the above technical solutions, compared with the prior art, the dustproof and waterproof optical lens storage box of this utility model, by setting humidity monitoring components and partitioning components inside the box and dividing the box's containing cavity into sections, ensures the sealing and dryness of the entire storage box. It can also monitor the humidity inside the box in real time, providing a clean and dry storage environment for optical lenses, facilitating long-term and convenient storage of optical lenses, and making it easy to carry.

Detailed Implementation
[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0023] Reference Figures 1 to 4This embodiment of an optical lens storage box that is dustproof and waterproof includes a detachably connected box body 1 and a box cover 2. The box body 1 has an internal cavity containing a partition component 4. The box cover 2 is provided with a humidity monitoring component 3 for monitoring the humidity of the cavity. In addition, the outer walls of the box body 1 have two first grooves 13 formed from their outer surfaces inward. The depth of the first grooves 13 is less than the wall thickness of the box body 1. The two first grooves 13 are provided to facilitate the provision of space for the hands when the storage box is handled.
[0024] A second groove 14 is provided around the accommodating cavity on the top surface of the box body 1. A sealing strip (not shown) is provided in the second groove 14. In this embodiment, the box cover 2 and the box body 1 are connected and locked by screws. The sealing strip can seal tightly when the box cover 2 and the box body 1 are connected, thereby ensuring the airtightness of the accommodating cavity and helping to keep the inside of the box body 1 dry.
[0025] Furthermore, such as Figure 2 and Figure 3 As shown, the partition assembly 4 includes a fixing plate 41, an air passage disposed on the fixing plate 41, a filter screen 42 covering one side of the through hole, and a handle 43 fixedly disposed on the side of the fixing plate 41 near the cover 2. The fixing plate 41 divides the receiving cavity into a first cavity 11 and a second cavity 12, and the first cavity 11 and the second cavity 12 are connected by the air passage, which is configured to allow gas to pass through and block solids from passing through. The first cavity 11 is located below the fixing plate 41, and the second cavity 12 is located above the fixing plate 41. The optical lens 5 is located in the first cavity 11, and the second cavity 12 contains a desiccant to ensure that the entire receiving cavity remains dry.
[0026] like Figure 2 and Figure 4 As shown, in this embodiment, the length of the first cavity 11 is less than the length of the second cavity 12, and the width of the first cavity 11 is less than the width of the second cavity 12, so that the top surface of the periphery of the first cavity 11 forms a support relative to the bottom surface of the second cavity 12, which facilitates the fixing and placement of the fixing plate 41. Specifically, the fixing plate 41 is connected and locked to the top surface of the periphery of the first cavity 11 by screws, and the outer peripheral edge of the fixing plate 41 is in contact with the inner wall of the box 1, and the bottom surface of the fixing plate 41 is also in contact with the top surface of the periphery of the first cavity 11. The fixing plate 41 is detachably connected to the box 1, which facilitates the insertion or removal of the optical lens 5 from the first cavity 11, and the handle 43 also facilitates the removal of the fixing plate 41 from the receiving cavity when disassembling it.
[0027] like Figure 4As shown, a plurality of optical lenses 5 are placed in the first cavity 11. These optical lenses 5 are detachably connected to the bottom surface of the fixing plate 41 or the bottom surface of the inner wall of the box 1. Adjacent optical lenses 5 are spaced apart. Only one optical lens 5 is disposed along the same depth direction of the first cavity 11. To ensure that the optical lenses 5 located in the first cavity 11 are not compressed, the thickness of the first cavity 11 is greater than the thickness of the optical lenses 5. In this embodiment, each optical lens 5 has a screw hole (not shown), which allows the optical lens 5 to be fixed to the bottom surface of the fixing plate 41 using screws.
[0028] Furthermore, such as Figure 3 As shown, the fixing plate 41 has multiple through holes spaced apart along its thickness. Each through hole's top surface (near the cover 2) is covered with a filter screen 42. The air passage is formed by the through holes and the corresponding filter screen 42. Each through hole is located within the orthographic projection of the corresponding filter screen 42 onto the fixing plate 41. The filter screen 42 ensures that only gas can pass between the first cavity 11 and the second cavity 12, preventing dust particles from passing through. This keeps the first cavity 11, where the optical lens 5 is placed, dry and dust-free, thus protecting the optical lens 5 from moisture corrosion and dust contamination. In this embodiment, one side of the filter screen 42 is adhesive, allowing it to directly correspond to the through holes and adhere to one side of the fixing plate 41.
[0029] Furthermore, such as Figure 1 As shown, the humidity monitoring component 3 includes a mounting part 31 and a humidity test strip 32. The mounting part 31 penetrates the thickness direction of the cover 2 and is fixedly connected to the cover 2. The outer periphery of the mounting part 31 is tightly fitted with the inner wall of the portion of the cover 2 through which the mounting part 31 penetrates. The height of the mounting part 31 is greater than the thickness of the cover 2. A through cavity penetrating its length direction is opened inside the mounting part 31, and the through cavity communicates with the second cavity 12.
[0030] A humidity test strip 32 is positioned at the top of the cavity and above the lid 2. A transparent cover is also fixedly installed at the top of the cavity, located on the side of the humidity test strip 32 away from the lid 2. The transparent cover ensures that the humidity test strip 32 is completely isolated from the outside, allowing for a more accurate reflection of the humidity level within the cavity. Furthermore, the transparent cover facilitates observation of the humidity test strip 32's condition, thus providing a more intuitive way to determine whether the interior of the box 1 is dry. In this embodiment, since the cavity within the mounting section 31 is connected to the second cavity 12, it can also be connected to the first cavity 11 via an air passage. When the desiccant in the second cavity 12 fails, the humidity inside the box 1 increases, further causing the humidity test strip 32 to change color. Therefore, the color change of the humidity test strip 32 can be used to determine whether the desiccant needs to be replaced. Additionally, when the humidity test strip 32 changes color, it needs to be replaced with a new one.
[0031] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
