Description

Technical Field

[0001] This utility model relates to the field of storage box technology, and in particular to a moisture-proof storage box for outdoor sketching paper. Background Technology

[0002] Outdoor plein air painting is an important way for artists to capture inspiration from nature, and the drawing paper they carry with them needs to be properly protected. However, the outdoor environment is complex and changeable, especially factors such as humidity, rain, and dew, which can easily cause paper artworks to become damp, deformed, moldy, or even damaged, seriously affecting the creative effect and the preservation value of the work. In addition, during the process of carrying and moving, the drawing paper is prone to shifting, rubbing, curling, or folding at corners in the drawing bag or folder, causing physical damage.

[0003] Currently, outdoor artists commonly use traditional easels or ordinary hard-shell storage boxes to store their canvases. While these devices offer some physical protection, they are significantly inadequate in effectively controlling the internal humidity environment. Users typically need to purchase and use bulk desiccant packets or boxes separately, placing them along with the canvas inside the easel or box. This method has several drawbacks: firstly, the desiccant may be misplaced and come into direct contact with the canvas, causing contamination or dents; secondly, the canvas is not securely fixed and is easily shifted and damaged during bumps or opening and closing. Clearly, there is a significant deficiency in existing technology: the lack of an integrated solution that reliably secures the canvas while providing stable and effective moisture protection, thus necessitating improvement.

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the present invention provides a moisture-proof storage box for outdoor sketching paper, comprising a box body 1 and a box lid 2.

[0027] The housing 1 contains a paper storage chamber 11 for storing drawing paper and a drying chamber 12 for storing desiccant. The paper storage chamber 11 and the drying chamber 12 are connected. The two chambers are connected by a physical channel for air circulation. The desiccant can actively absorb moisture in the paper chamber, forming a stable moisture-proof microenvironment, while avoiding direct contact between the desiccant and the drawing paper to prevent contamination or indentation.

[0028] The drawing paper storage cavity 11 is equipped with a paper-fixing structure 3 to hold the drawing paper in place; by applying a restraining force to the drawing paper, it prevents the drawing paper from shifting, folding, or being damaged by friction during transportation.

[0029] An opening 13 is provided on one side of the drawing paper storage cavity 11, and the box cover 2 is placed over the opening 13 of the box body 1; the opening 13 provides a path for storing and retrieving drawing paper, and the box cover 2 enables the opening and closing of the opening 13 to achieve sealing. This simplifies the operation process, ensures the airtightness of the box body 1, and facilitates the retrieval and placement of drawing paper.

[0030] When using, open the lid 2, fix the drawing paper inside the paper-fixing structure 3, and close the lid 2 to fix the drawing paper inside the box 1. The lid 2 and the box 1 isolate external dust, rainwater and other pollutants, and at the same time prevent the drawing paper from being easily moved and damaged when bumped or opened and closed. Place a desiccant in the drying chamber 12. The desiccant absorbs the moisture in the drawing paper chamber, keeping the drawing paper dry and providing stable and effective moisture protection for the drawing paper. At the same time, it avoids direct contact between the desiccant and the drawing paper, which may cause contamination or indentation.

[0031] like Figures 2 to 4 As shown, the paper-fixing structure 3 in this embodiment includes a limiting groove 31 disposed on the inner wall of the drawing paper storage cavity 11, a drawing paper storage plate 32 inserted in the limiting groove 31, and a paper storage slot 33 for storing drawing paper on the drawing paper storage plate 32.

[0032] Specifically, the limiting groove 31 is a concave groove, which forms a physical guide rail to provide a precise insertion and removal path for the drawing paper storage plate 32 and prevent the storage plate from shifting.

[0033] The removable drawing paper storage plate 32 serves as a base for supporting the drawing paper, enabling the entire drawing paper to be placed and removed, keeping the drawing paper flat and avoiding curling or folding, which could cause physical damage.

[0034] The paper storage tray 33 on the paper storage plate 32 divides the paper into independent spaces, physically isolating each sheet of paper to prevent them from rubbing and sticking together, while also limiting the position of the paper to prevent it from shifting laterally.

[0035] Preferably, a clearance hole (not shown) is provided at the edge of the paper storage plate 32, which penetrates the paper storage slot 33, so that the paper in the paper storage slot 33 is exposed through the clearance hole (not shown), and the paper can be easily taken out through the clearance hole (not shown).

[0036] like Figure 1 As shown, a transparent surface 14 is provided on one side of the drawing paper storage cavity 11 in this embodiment. The transparent surface 14 is made of PC plastic, acrylic or tempered glass. The optical transmittance of the transparent surface 14 material enables visual penetration, allowing direct observation of the state of the drawing paper inside the drawing paper storage cavity 11 without opening the box, and reducing the entry of external moisture into the drawing paper storage cavity 11.

[0037] like Figures 1 to 3 As shown, the drying chamber 12 in this embodiment is provided with a vent 121 that communicates with the paper storage chamber 11. The vent 121 enables communication between the drying chamber 12 and the paper storage chamber 11. Through the vent 121, the desiccant in the drying chamber 12 can exchange gases with the air in the paper storage chamber 11. The desiccant absorbs moisture from the air in the paper storage chamber 11, thereby reducing the humidity inside the paper storage chamber 11. This effectively controls the humidity environment inside the paper storage chamber 11, preventing the paper from becoming damp, deformed, moldy, or even damaged due to moisture, rain, dew, or other factors.

[0038] Specifically, several small holes are made on the wall of the drying chamber 12 as air vents 121. The size and number of holes can be adjusted according to actual needs to ensure good air permeability while preventing desiccant leakage.

[0039] like Figure 2 and Figure 3 As shown, the drying chamber 12 in this embodiment is provided with a desiccant inlet 122, and a sealing cover 123 is provided at the desiccant inlet 122.

[0040] Specifically, a desiccant inlet 122 is provided, offering an operational channel for the insertion and replacement of the desiccant. This allows users to conveniently place the desiccant into the drying chamber 12 according to actual needs. Regular desiccant replacement is also facilitated, ensuring the desiccant remains in a good moisture-absorbing state, thereby continuously and effectively controlling the humidity of the paper storage environment and preventing the paper from becoming damp and damaged.

[0041] The sealing cap 123 can seal the desiccant inlet 122, preventing outside humid air from entering the drying chamber 12 through the inlet, while also preventing desiccant from leaking out, maintaining a relatively independent dry environment inside the drying chamber 12. This enhances the sealing performance of the drying chamber 12 and further improves the moisture-proof effect.

[0042] Preferably, the sealing cap 123 can be made of rubber. Rubber has good elasticity and sealing properties, which can fit tightly against the desiccant inlet 122 and effectively prevent air and desiccant leakage. The sealing cap 123 can also be made of plastic, which fits into the structure of the desiccant inlet 122 to achieve a sealing effect.

[0043] like Figure 1 As shown, the bottom of the housing 1 in this embodiment is equipped with a roller 15. Utilizing the rolling friction characteristics of the roller 15, when an external force is applied to the housing 1, the roller 15 contacts the ground and rolls, transforming the original sliding friction between the housing 1 and the ground into rolling friction. This allows users to easily move the housing 1 in outdoor environments.

[0044] like Figure 1 As shown, a telescopic pull rod 16 is provided on one side of the suitcase 1 in this embodiment. The telescopic pull rod 16 is a conventional telescopic pull rod (Samsonite suitcase pull rod or Diplomatic suitcase pull rod). The telescopic pull rod 16 is generally composed of multiple sleeves, and the extension and fixation are achieved by the friction between the sleeves or the buckle structure. When the user applies a pulling force, the pull rod can freely extend and retract by overcoming the friction between the sleeves or the resistance of the buckle; after reaching the appropriate length, the pull rod is fixed at the current length by relying on friction or the buckle. Through this telescopic mechanism, the user can adjust the length of the pull rod according to their own height and movement needs, so as to pull the suitcase 1 in a comfortable posture.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the box body 1 and the box cover 2 are hinged together, and a combination lock 17 is provided between the box body 1 and the box cover 2.

[0046] Specifically, the box body 1 and the box lid 2 are connected by a hinge, with the hinge axis serving as the rotation center, allowing the box lid 2 to open and close relative to the box body 1. This makes it convenient for users to open and close the box body 1, and the operation is simple and quick.

[0047] The combination lock 17 is a conventional mechanical lock (such as the Sanhuan S601 mechanical combination padlock or the Jindian Yuanzi mechanical combination lock 17 JD-888) or electronic lock (such as the Xiaomi Smart Door Lock E10 or the Deshman Electronic Combination Lock 17 Q5M). Users input a pre-set password, triggering the internal unlocking mechanism to disengage the bolt from the latch, thus opening the lid 2. If the password is incorrect or not entered, the bolt remains engaged with the latch, preventing the lid 2 from opening. This provides security for important items such as drawings inside the box 1, preventing unauthorized access and protecting the user's creative work and belongings.

[0048] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
