Description

Technical Field

[0001] This utility model relates to the field of dust cover technology, and in particular to an adjustable-size dust cover. Background Technology

[0002] The main function of dust covers is to protect equipment or items from the intrusion of dust, debris, and other contaminants, thereby extending their service life, improving operational stability, and reducing maintenance costs.

[0003] Traditional dust covers typically consist of a rigid frame and a cover fabric, with the frame and fabric fixed together. The cover fabric is kept in an unfolded state by the support of the frame. In use, the dust cover is placed over the target object to primarily protect the top of the object from dust. However, this traditional design has significant limitations: due to its fixed frame structure dimensions, it is often impossible to flexibly adjust the size of the cover when protecting objects of different sizes. This results in the dust cover not being able to completely cover the target object, thus affecting the dust protection effect. Therefore, this solution proposes an adjustable-size dust cover to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-size dust cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-size dust cover, comprising:

[0006] Dust cover cloth;

[0007] A base, wherein the base is disposed at the bottom of the dust cover;

[0008] An adjusting block is provided on one side of the base and is used to adjust the width of the dust cover cloth;

[0009] A movable component is disposed at the connection between the base and the adjusting block, and the movable component is used to move the position of the adjusting block;

[0010] A fixing component is provided at the connection between the dust cover and the base, and the fixing component is used to fix the dust cover and the base.

[0011] Preferably, the moving component includes:

[0012] A toothed plate is fixedly connected to one side of the adjusting block, and a limiting component is provided at the connection between the toothed plate and the base;

[0013] A gear that meshes on one side of a toothed plate;

[0014] A rotating component is disposed in the middle of the gear and is used to rotate the gear.

[0015] Preferably, the rotating component includes a rotating column that is inserted into the middle of the gear, a fixed bearing is sleeved at the bottom end of the rotating column, and a torsion cap is fixedly connected to the top end of the rotating column.

[0016] Preferably, the base has a cavity in the middle, the gear is inserted into the cavity, and the fixed bearing is inserted into the inner wall at the bottom of the cavity.

[0017] Preferably, the limiting member includes an insertion hole formed in the middle of the base, and the cavity communicates with the insertion hole.

[0018] Preferably, a limiting block is fixedly connected to the inner wall of the through hole on the side away from the gear, and a limiting hole is opened on the side of the tooth plate near the limiting block, with the limiting block inserted into the limiting hole.

[0019] Preferably, the fixing component includes a pressing plate disposed on the top of the dust cover, the pressing plate having a through hole in the middle, the toggle cap being inserted into the inside of the through hole, and the top of the pressing plate being threadedly connected with a bolt for fixing the position of the pressing plate.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] This utility model, through the design of a base, adjusting blocks, a moving component, and a fixing component, allows the base to be placed on top of the object to be covered during use.

[0027] 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.

[0028] This utility model provides, for example Figure 1-4 Shown:

[0029] Example 1:

[0030] Adjustable size dust covers, including:

[0031] Dust cover cloth 1;

[0032] Base 2, which is located at the bottom of the dust cover 1;

[0033] Adjusting block 3 is located on one side of base 2 and is used to adjust the width of dust cover cloth 1;

[0034] Movable component 4 is located at the connection between base 2 and adjusting block 3, and is used to move the position of adjusting block 3.

[0035] Fixing component 6 is located at the connection between the dust cover 1 and the base 2. Fixing component 6 is used to fix the dust cover 1 and the base 2.

[0036] It should be noted that the dust cover 1 is used to cover the object and block dust, preventing dust from falling onto the object. In use, the base 2 is placed on top of the object to be covered, and the adjusting block 3 is moved by the moving component 4 to adjust the top of the dust cover 1 to the required width. The dust cover 1 is then placed on top of the object, so that the base 2 is in contact with the object. Finally, the two adjusting blocks 3 are moved to fit against the two sides of the object, preventing the dust cover 1 from moving randomly on top of the object.

[0037] Specifically, mobile component 4 includes:

[0038] Toothed plate 406 is fixedly connected to one side of adjusting block 3, and a limiting member 5 is provided at the connection between toothed plate 406 and base 2;

[0039] Gear 405 meshes on one side of tooth plate 406;

[0040] A rotating component is located in the middle of gear 405 and is used to rotate gear 405.

[0041] Specifically, the rotating component includes a rotating column 403 that is inserted into the middle of the gear 405. A fixed bearing 404 is sleeved at the bottom end of the rotating column 403, and a torsion cap 401 is fixedly connected to the top end of the rotating column 403.

[0042] Specifically, a cavity 402 is provided in the middle of the base 2, a gear 405 is inserted and connected inside the cavity 402, and a fixed bearing 404 is inserted and connected to the inner wall at the bottom of the cavity 402.

[0043] It should be noted that the cavity 402 is adapted to the gear 405, allowing the gear 405 to rotate inside the cavity 402. The fixed bearing 404 is an existing ball bearing. During use, the fixed bearing 404 fixes the position of the rotating column 403 without affecting its rotation. When the position of the adjusting block 3 needs to be moved, the torsion cap 401 drives the rotating column 403 and the gear 405 to rotate. The gear 405 drives the toothed plate 406 that meshes with it to move. The toothed plate 406 then drives the adjusting block 3 to adjust its position.

[0044] Specifically, the limiting component 5 includes an insertion hole 502 opened in the middle of the base 2, and the cavity 402 and the insertion hole 502 are interconnected.

[0045] Specifically, a limiting block 501 is fixedly connected to the inner wall of the through hole 502 on the side away from the gear 405, and a limiting hole 503 is opened on the side of the tooth plate 406 near the limiting block 501, with the limiting block 501 inserted into the limiting hole 503.

[0046] It should be noted that the through hole 502 is adapted to the toothed plate 406, allowing the toothed plate 406 to slide inside the through hole 502. The limiting block 501 is adapted to the limiting hole 503. When the toothed plate 406 moves, it moves on one side of the limiting block 501 through the limiting hole 503. When the toothed plate 406 moves to the point where the limiting block 501 fits against the inner wall of the limiting hole 503, the limiting block 501 prevents the toothed plate 406 from moving further, thus limiting the moving distance of the toothed plate 406.

[0047] Example 2:

[0048] Fixing component 6 is used in the dust cover of embodiment one;

[0049] Specifically, the fixing component 6 includes a pressing plate 601 set on the top of the dust cover 1. A through hole 603 is opened in the middle of the pressing plate 601. A twist cap 401 is inserted into the inside of the through hole 603. A bolt 602 for fixing the position of the pressing plate 601 is threaded through the top of the pressing plate 601.

[0050] It should be noted that a hole adapted to the twist cap 401 is provided in the middle of the dust cover 1. When it is necessary to fix the position of the dust cover 1, the twist cap 401 can pass through the hole, so that the dust cover 1 and the base 2 can be fitted together.

[0051] Furthermore, when it is necessary to fix the dust cover 1 to the base 2, first, the dust cover 1 and the base 2 are attached together, then the pressing plate 601 is placed on the twist cap 401, so that the pressing plate 601 and the dust cover 1 are attached together, and finally the bolts 602 are passed through the pressing plate 601, the dust cover 1 and the base 2 in sequence, so as to fix the pressing plate 601, the dust cover 1 and the base 2 together by the bolts 602.

[0052] 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.
