Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal duster technology, specifically a dust removal duster angle stepless adjustment structure. Background Technology
[0002] A duster is a common cleaning product. Existing dusters can be used to clean various furniture, appliances, and walls, and can brush away dust from the surface of objects.
[0003] When cleaning the top of furniture with a duster, the angle of the duster needs to be adjusted to reach hard-to-clean areas such as corners and angled edges. Existing dusters have the function of changing the angle, but this function is generally geared towards duster storage or simply adding a simple vertical stop on the basis of storage. This still has limitations for use in some scenarios and cannot meet the needs of different scenarios.
[0004] Therefore, it is necessary to improve the existing dust collectors. Utility Model Content
[0005] To address the problems in related technologies, this utility model provides a stepless adjustment structure for the angle of a duster, solving the problem that the angle adjustment function of traditional dusters cannot meet the needs of multiple scenarios.
[0006] To solve the above problems, the following technical solutions are provided:
[0007] The dust removal duster angle stepless adjustment structure of this utility model includes a handle and a fork, which are rotatably connected. The rotating parts of the handle and the fork are provided with a friction suspension structure, which includes two mutually cooperating friction components. By adjusting the friction force between the friction components, the handle and the fork can be suspended at multiple angles.
[0008] The above solution uses a friction-suspending structure instead of the traditional toothed block engagement, making operation more convenient. The angle of the folding part can be easily adjusted according to actual needs, improving the applicability of the foldable duster in different cleaning scenarios.
[0009] One end of the grip has an arc-shaped concave portion, and one end of the fork has an arc-shaped convex portion. The arc-shaped concave portion and the arc-shaped convex portion are concentrically arranged, and the inner surface of the arc-shaped concave portion slides in contact with the outer surface of the arc-shaped convex portion. The friction component includes two actuating plates, one actuating plate is located on the inner surface of the arc-shaped concave portion, and the other actuating plate is located on the outer surface of the arc-shaped convex portion.
[0010] The above solution uses two friction plates at the rotating parts of the handle and fork, specifically between the concave and convex arcs. These two plates ensure stable friction, making the folding part more reliably suspended, reducing angle changes caused by accidental slippage, and improving the stability of cleaning operations.
[0011] The working sheet is a rubber sheet.
[0012] The above solution uses rubber sheets as the working material. The sufficient friction between the two rubber sheets can reliably suspend the folded part, reduce the angle change caused by accidental slippage, and further ensure the stability of the cleaning work.
[0013] The surfaces of the two contacting plates have anti-slip textures.
[0014] The above solution features anti-slip textures on the contact surface between the two action plates. The anti-slip textures of the two action plates contact each other, ensuring reliable suspension of the folded part. At the same time, the reasonable design of the anti-slip textures allows the duster to be folded and stored with less force compared to the rubber sheet, improving the convenience of cleaning.
[0015] The anti-slip texture consists of diamond-shaped protrusions evenly distributed on the surface of the action piece. The diamond-shaped protrusions of the two action pieces are staggered and the height of the diamond-shaped protrusions is 1-5mm.
[0016] The anti-slip texture of the above solution is set as diamond-shaped protrusions. The diamond protrusions on the two working plates are staggered, which can not only ensure friction but also improve the smoothness of user operation. Furthermore, by adjusting the height of the diamond protrusions, the effect of the duster can be greatly improved. Limiting the height of the diamond protrusions to the range of 1-5mm can ensure sufficient friction without making the movement between friction parts too difficult or generating too much resistance due to excessive protrusion, thus affecting the smoothness of user operation.
[0017] The rhomboid protrusion has sloping sides, and the sloping sides transition to the top surface of the rhomboid protrusion with a rounded arc.
[0018] The anti-slip texture of the above solution is based on the diamond-shaped protrusions, with the surrounding area of the diamond protrusions being beveled and rounded, which further improves the smoothness of user operation and enhances the user experience.
[0019] The concave part is an arc-shaped plate bent at one end of the grip. A rotating shaft is fixedly connected to the inner side of the arc-shaped plate. The convex part is a bushing fixed at one end of the fork. The bushing is sleeved to both ends of the rotating shaft. One actuating plate is located on the inner surface of the arc-shaped plate, and the other actuating plate is located on the outer surface of the bushing.
[0020] The above-mentioned scheme has a specific connection between the concave and convex arc parts, which is achieved by the arc plate and the bushing through the rotating shaft connected to the arc plate. When the arc plate rotates around the bushing, the action plate on the inner surface of the arc plate and the action plate on the outer surface of the bushing are suspended by friction. At the same time, the friction suspension structure is adopted, which makes the dust duster free of extra structure, more compact and improves the overall appearance and performance of the dust duster.
[0021] The two ends of the rotating shaft extend outward and are threaded at both ends. The rotating shaft passes through the bushing and is fastened to the nut by threaded connection.
[0022] The above solution features threads at both ends of the pivot shaft for connecting fastening nuts. By tightening or loosening the fastening nuts, the friction between the rotating parts of the grip and the fork can be adjusted, improving ease of use.
[0023] The end of the grip furthest from the fork is connected to at least one connecting rod, and the end of the connecting rod furthest from the fork is connected to a tail cone. The connecting rod is threadedly connected to the grip, the connecting rod to the tail cone, and the connecting rod itself.
[0024] The above solution makes the duster expandable, allowing the handle to be lengthened by one or more extension rods, ensuring flexibility and applicability in different usage scenarios.
[0025] The flanges on both sides of the fork are equipped with anti-detachment blocks for connecting the duster head.
[0026] The above solution incorporates anti-slip blocks to prevent the duster cloth from slipping off, thereby improving the effectiveness of the duster head.
[0027] The above solution has the following advantages:
[0028] 1. The duster features a stepless angle adjustment structure, including a handle and a fork. The handle and fork are rotatably connected, and the rotating parts of the handle and fork are equipped with a friction suspension structure. The friction suspension structure includes two cooperating friction components. By adjusting the friction between the friction components, the handle and fork can be suspended at multiple angles. The friction suspension structure replaces the traditional toothed block engagement, making operation more convenient. The angle of the folding part can be easily adjusted according to actual needs, improving the applicability of the foldable duster in different cleaning scenarios.
[0029] 2. One end of the handle has a concave arc, and one end of the fork has a convex arc. The concave and convex arcs are concentrically arranged, and the inner surface of the concave arc slides in contact with the outer surface of the convex arc. The friction component includes two actuating plates: one actuating plate is located on the inner surface of the concave arc, and the other actuating plate is located on the outer surface of the convex arc. Two mutually rubbing actuating plates are used at the rotating parts of the handle and fork, i.e., between the concave and convex arcs. These two actuating plates ensure stable friction, making the folding part more reliably suspended, reducing angle changes caused by accidental slippage, and improving the stability of cleaning operations.

[0039] 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.
[0040] like Figures 1 to 3 As shown, the stepless adjustment structure for the duster angle in the first embodiment includes a handle 1 and a fork 2. One end of the handle 1 has an arc-shaped concave portion, and one end of the fork 2 has an arc-shaped convex portion. The arc-shaped concave portion and the arc-shaped convex portion are concentrically arranged, and the inner surface of the arc-shaped concave portion slides in contact with the outer surface of the arc-shaped convex portion. The friction component includes two actuating plates 3, one actuating plate 3 is located on the inner surface of the arc-shaped concave portion, and the other actuating plate 3 is located on the outer surface of the arc-shaped convex portion. Anti-slip blocks 202 for connecting the duster head are provided on the flanges on both sides of the fork 2. By setting the anti-slip blocks 202, the duster cloth is prevented from slipping, thus improving the effectiveness of the duster head. It can be seen that two mutually rubbing actuating plates 3 are used at the rotating parts of the handle 1 and the fork 2, that is, between the arc-shaped concave portion and the arc-shaped convex portion. The two actuating plates 3 ensure a stable frictional force, making the folded part hang more reliably, reducing angle changes caused by accidental slippage, and improving the stability of the cleaning work.
[0041] Combination Figure 4 As shown, the concave part is an arc-shaped plate 101 bent at one end of the handle 1. A support seat 6 is fixedly connected to the inner side of the arc-shaped plate 101. The two ends of the support seat 6 are provided with rotating shafts 4. The convex part is a bushing 201 fixed to one end of the fork 2. There are two bushings 201. The two ends of the bushing 201 are sleeved with the rotating shafts 4. One action piece 3a is provided on the inner surface of the arc-shaped plate 101, and the other action piece 3b is provided on the outer surface of the bushing 201. The concave part and the convex part are specifically connected by the arc-shaped plate 101 and the bushing 201 through the rotating shafts 4 connected to the arc-shaped plate 101. When the arc-shaped plate 101 rotates around the bushing 201, the action piece 3a on the inner surface of the arc-shaped plate 101 and the action piece 3b on the outer surface of the bushing 201 achieve suspension through friction. At the same time, the friction suspension structure makes the duster free of extra structure, making the whole more compact and improving the overall appearance and performance of the duster.
[0042] Furthermore, in this embodiment, a rubber sheet is selected as the working piece 3. Sufficient friction between the two rubber sheets can reliably suspend the folded part, reduce angle changes caused by accidental slippage, and further ensure the stability of the cleaning work.
[0043] The stepless angle adjustment structure of the duster in the second embodiment, compared with the first embodiment, has anti-slip textures on the surfaces of the two contacting plates 3. By setting the anti-slip textures, the two contacting plates 3 can be reliably suspended when in contact. At the same time, the reasonable setting of the anti-slip textures can make the duster require less force when folding and storing compared to a rubber sheet, thus improving the convenience of cleaning.
[0044] As an example, the anti-slip texture can be diamond-shaped protrusions 301 evenly distributed on the surface of the action piece 3, such as... Figure 5 As shown, the rhomboid protrusions 301 on the two action plates 3 are staggered, and the height of the rhomboid protrusions 301 is 1-5mm. By setting the anti-slip texture as rhomboid protrusions 301 and staggering the rhomboid protrusions 301 on the two action plates 3, both friction and smoothness of user operation can be guaranteed. Furthermore, adjusting the height of the rhomboid protrusions 301 can significantly improve the performance of the duster. Limiting the height of the rhomboid protrusions 301 to the range of 1-5mm ensures sufficient friction without causing excessive difficulty in movement between friction components or generating excessive resistance due to excessive protrusion, thus affecting the smoothness of user operation.
[0045] Furthermore, the rhomboid protrusion 301 can be beveled around its perimeter, with the beveled surface transitioning to the top surface of the rhomboid protrusion 301 using a rounded transition. This allows the anti-slip texture to be enhanced by setting the rhomboid protrusion 301's perimeter to be beveled and rounded, further improving the smoothness of user operation and enhancing the user experience.
[0046] like Figure 6 As shown, in the third embodiment of the stepless adjustment structure for the dust removal angle, compared with the first embodiment, the two ends of the rotating shaft 4 extend outward and are threaded at both ends. The rotating shaft 4 penetrates the bushing 201 and is connected to the fastening nut 7 via the thread. The threads at both ends of the rotating shaft 4 are used to connect to the fastening nut 7. By tightening or loosening the fastening nut 7, the friction of the rotating parts between the handle 1 and the fork 2 can be adjusted, improving the ease of use.
[0047] like Figure 7 As shown, in the fourth embodiment of the duster's stepless angle adjustment structure, compared to the first embodiment, at least one connecting rod 5 is connected to the end of the handle 1 furthest from the fork 2. The end of the connecting rod 5 furthest from the fork 2 is connected to a tail cone. The connecting rod 5 is threadedly connected to the handle 1, the tail cone, and to the handle itself. This makes the duster expandable; the handle 1 can be lengthened using one or more connecting rods 5, ensuring flexibility and applicability in different usage scenarios.
[0048] In the above embodiment, the handle 1 and the fork 2 are rotatably connected. A friction-suspending structure is provided at the rotatable parts of the handle 1 and the fork 2. This friction-suspending structure includes two cooperating friction components. By adjusting the friction between these components, the handle 1 and the fork 2 can be suspended at multiple angles. Using a friction-suspending structure instead of the traditional toothed engagement makes operation more convenient, and the angle of the folding part can be easily adjusted according to actual needs, improving the applicability of the foldable duster in different cleaning scenarios.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
