Description

Technical Field

[0001] This utility model relates to the field of dustproof technology for art display cases, specifically an art display case with dustproof function. Background Technology

[0002] Art display cases are specialized furniture or structures used to display and protect valuable items such as artworks, cultural relics, and collectibles. They are not merely containers, but key elements that enhance the aesthetic appeal of exhibits, ensure their safety, and create a specific atmosphere. Chinese Patent No. CN202420007019.8 discloses a multi-layered display case with adjustable layer spacing, including a base cabinet. A groove is formed in the center of one side of the base cabinet, and a ventilation component is fixedly connected inside the groove. Cabinet doors are hinged to both sides of the base cabinet. Support columns are fixedly connected around the top of the base cabinet, and several sets of adjustment components are slidably connected to the surface of the support columns. A dustproof plate is fixedly connected to the top surface of the support columns, and suction cup components A are adsorbed onto the surface of the dustproof plate and both sides of the base cabinet. This multi-layered display case with adjustable spacing allows for easy adjustment of the components. During use, turning the adjusting bolt loosens the locking block, allowing it to slide on the surface of the support column. Once the desired height is determined, turning the adjusting bolt again causes the pressure plate to press against the support column, fixing the display shelf in the required position. This improves space utilization and applicability, and prevents the display effect from being affected by the different sizes of exhibits.

[0003] Based on the above, the inventors have identified the following problem: While the aforementioned adjustable shelf device effectively improves the space utilization and exhibit adaptability of the display case, solving the display effect problem caused by differences in exhibit size, this design overlooks the cleaning challenges inside the display case. Currently, cleaning the interior of the display case still requires manual work by staff. Given that the items inside art display cases are usually extremely valuable, such cleaning operations carry a high risk of accidentally damaging the artwork, potentially causing incalculable losses. Utility Model Content

[0004] The purpose of this utility model is to provide an art display case with dustproof function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an art display case with dustproof function, comprising a cabinet body, a pair of limiting shafts symmetrically arranged on both sides of the cabinet body, each limiting shaft rotatably mounting several cabinet doors, and two cabinet doors at the same height on the left and right sides being able to close to each other; a connecting piece is fixedly mounted on the cabinet door, the connecting piece being rotatably sleeved on the corresponding limiting shaft; the cabinet body has a placement cavity and an operating cavity located on one side of the placement cavity; a fixed connecting shaft is provided in the placement cavity, a connecting sleeve is rotatably sleeved on the connecting shaft, and a rotating fan is provided on the connecting sleeve; one end of the connecting shaft passes through the placement cavity and the operating cavity and is fixedly connected to the inner wall of the operating cavity; a roller is fixedly mounted on the part of the connecting sleeve that extends through the placement cavity into the operating cavity, and a connecting line is fixedly connected to the roller; an adjusting column is provided in the operating cavity at the turning point of the inner wall of the cabinet, and a pulley is rotatably mounted on the adjusting column; the connecting line passes around the pulley and is connected to the corresponding connecting piece; a coil spring is provided between the connecting sleeve and the connecting shaft.

[0006] Furthermore, the inner end of the coil spring is fixedly connected to the circumferential surface of the connecting shaft, and the outer end of the coil spring is fixedly connected to the inner circumferential wall of the connecting sleeve.

[0007] Furthermore, both ends of the connecting shaft are fixedly connected to the inner wall of the cabinet.

[0008] Furthermore, bearings are provided at the positions where the outer side of the connecting sleeve contacts the inner wall of the cabinet.

[0009] Furthermore, a bearing is also provided between the inner peripheral wall of the connecting sleeve and the outer peripheral surface of the connecting shaft, and the bearing is arranged axially adjacent to the coil spring.

[0010] Furthermore, both the placement cavity and the operating cavity have filter surfaces on their sidewalls, and the filter surfaces are axially aligned with the connecting shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this art display case with dustproof function is reasonable and has the following advantages:

[0012] (1) When the cabinet door is opened, the user's action of pulling the cabinet door drives the roller and connecting sleeve to rotate synchronously through the connecting line, causing the rotating fan to rotate in the forward direction, forming an airflow barrier that blows outward at the cabinet door; this airflow effectively blocks the external dust-laden air from entering the placement cavity, preventing dust from entering at the moment the cabinet is opened; at the same time, this process allows the coil spring to automatically store energy without additional operation; when the cabinet door is closed, the coil spring releases energy to drive the rotating fan to rotate in reverse at high speed, forming a directional airflow in the cabinet, forcibly pushing the suspended dust to the filter surface for concentrated interception; the physical action of opening and closing the cabinet door is directly converted into active dust prevention power, forming a dual protection mechanism of "dust blocking when the door is open and dust removal when the door is closed", which greatly improves the cleanliness guarantee of exhibits during frequent storage and retrieval;

[0013] (2) Through mechanical linkage design, manual operation is transformed into dust removal energy, realizing closed-loop cleaning with "zero human intervention" throughout the process; after the cabinet door is closed, the coil spring automatically drives the rotating fan to reverse, so that the air in the placement cavity passes through the directional circulation filter surface and continuously adsorbs dust particles; users only need to replace or clean the snap-fit ​​filter surface regularly to maintain efficient dust removal, completely avoiding the accidental risks such as collisions and scratches that may occur when staff enter the cabinet with tools to clean in traditional display cases; especially for fragile and precious artworks, this design replaces high-risk manual operation with a pure mechanical structure, fundamentally solving the contradiction between cleaning safety and operation convenience.

[0020] Please see Figure 1-4 The present invention provides a technical solution as follows:

[0021] Example:

[0022] An art display case with dustproof function includes a cabinet body 1. A pair of limiting shafts 6 are symmetrically arranged on both sides of the cabinet body 1. Several cabinet doors 2 are rotatably mounted on each limiting shaft 6, and two cabinet doors 2 at the same height can close together. Connecting pieces 4 are fixedly mounted on each cabinet door 2, and the connecting pieces 4 are rotatably sleeved on the corresponding limiting shafts 6. The cabinet body 1 has a placement cavity 8 and an operating cavity 7 located on one side of the placement cavity 8. A fixed connecting shaft 12 is arranged inside the placement cavity 8, and a connecting sleeve 15 is rotatably sleeved on the connecting shaft 12. A rotating fan 11 is provided on the connecting sleeve 15; one end of the connecting shaft 12 passes through the placement cavity 8 and the operating cavity 7 and is fixedly connected to the inner wall of the operating cavity 7; a scroll 13 is fixedly provided on the part of the connecting sleeve 15 that passes through the placement cavity 8 and extends into the operating cavity 7, and a connecting line 5 is fixedly connected to the scroll 13; an adjusting column 9 is provided in the operating cavity 7 at the turning point of the inner wall of the cabinet 1, and a pulley 10 is rotatably provided on the adjusting column 9; the connecting line 5 passes around the pulley 10 and is connected to the corresponding connecting piece 4; a coil spring 16 is provided between the connecting sleeve 15 and the connecting shaft 12.

[0023] The inner end of the coil spring 16 is fixedly connected to the circumferential surface of the connecting shaft 12, and the outer end of the coil spring 16 is fixedly connected to the inner circumferential wall of the connecting sleeve 15.

[0024] The two ends of the connecting shaft 12 are fixedly connected to the inner wall of the cabinet 1.

[0025] Bearings 14 are provided at the positions where the outer side of the connecting sleeve 15 contacts the inner wall of the cabinet 1.

[0026] A bearing 14 is also provided between the inner peripheral wall of the connecting sleeve 15 and the outer peripheral surface of the connecting shaft 12, and the bearing 14 and the coil spring 16 are arranged adjacent to each other in the axial direction.

[0027] The side walls of both the placement cavity 8 and the operating cavity 7 are provided with filter surfaces 3, which are axially aligned with the connecting shaft 12. The filter surfaces 3 are used to trap dust and prevent it from re-entering the display space.

[0028] Working principle:

[0029] Cabinet door 2 opens (energy storage stage): When the user pulls cabinet door 2 outward, cabinet door 2 drives connecting line 5 through connector 4; connecting line 5 passes around pulley 10 to pull roller 13, forcing roller 13 to rotate and drive connecting sleeve 15 to rotate around fixed connecting shaft 12. The rotation of connecting shaft 12 drives rotating fan 11 to rotate in the forward direction, so that the air inside cabinet 1 blows out towards cabinet door 2, thereby preventing dusty air from entering cabinet 1 when cabinet door 2 is opened. At this time, coil spring 16 is torsion energy storage. The inner end of coil spring 16 is fixed to shaft, and the outer end is fixed to sleeve. Energy is stored when they rotate relative to each other.

[0030] Cabinet door 2 closes (dust removal stage): After the cabinet door 2 is released, the coil spring 16 releases its elasticity and drives the connecting sleeve 15 to rotate in the opposite direction; the rotating fan 11 on the connecting sleeve 15 rotates synchronously in the opposite direction at high speed, forming a directional airflow from inside the cabinet 1 toward the filter surface 3, thereby pushing the floating dust toward the filter surface 3, realizing the air purification of the cabinet 1 and the artwork inside. Only periodic cleaning of the filter surface 3 is required. The filter surface 3 can be locked to the inner wall of the cabinet 1 for easy cleaning by subsequent operators.
