Description

Technical Field

[0001] This utility model relates to the field of whitewashing technology for tree trunks in plant gardens, and in particular to a novel whitewashing roller brush for tree trunks. Background Technology

[0002] Applying whitewash to tree trunks by rolling it on reflects sunlight, reduces heat absorption, lowers the temperature difference between day and night, and prevents the bark from cracking due to frost. At the same time, the lime and sulfur in the whitewash have bactericidal and insecticidal properties, preventing pests from laying eggs and overwintering on the trunk, thus reducing the occurrence of diseases and pests.

[0003] In existing technologies, roller brushes are generally used to whiten tree trunks. However, existing roller brushes are generally designed for flat objects such as walls, boards, and billboards. Roller brushes cannot bend to conform to the shape of tree trunks. As a result, when using a conventional roller brush to apply paint to the curved surface of tree trunks or columns, the area covered each time is small. Users need to walk around the tree trunk and roll it up and down multiple times to whiten the outer surface of the tree trunk. This is time-consuming, labor-intensive, and results in a poor user experience and unsatisfactory whitening effect. Utility Model Content

[0004] The purpose of this invention is to provide a novel tree trunk whitening roller brush, which aims to at least solve the technical problem in the prior art that roller brushes cannot be bent to conform to the shape of tree trunks.

[0005] To achieve the above objectives, firstly, the technical solution of this utility model provides a novel tree trunk whitening roller brush, the key points of which include:

[0006] Handle holder;

[0007] A shaft, which is connected to the handle bracket, the shaft including a first support shaft end and a second support shaft end opposite to each other;

[0008] A roller sleeve assembly, comprising a flexible roller sleeve and a first wheel group and a second wheel group arranged opposite to each other, wherein the two ends of the flexible roller sleeve are respectively sleeved on the first wheel group and the second wheel group, the first wheel group is rotatably mounted on the end of a first support shaft, and the second wheel group is rotatably mounted on the end of a second support shaft;

[0009] An elastic element is disposed on the shaft;

[0010] The first wheel set and the second wheel set can move towards each other to make the flexible roller sleeve bend, and the elasticity of the elastic element can make the first wheel set and the second wheel set move away from each other to make the flexible roller sleeve straighten.

[0011] Furthermore, the shaft is formed by bending a strip structure, and the first support shaft end and / or the second support shaft end of the shaft are connected to the handle bracket;

[0012] Alternatively, the shaft may be composed of two separate strip structures, one of which is a first support shaft end and the other is a second support shaft end. The handle bracket may have a first support arm and a second support arm arranged opposite to each other, with the first support shaft end connected to the first support arm and the second support shaft end connected to the second support arm.

[0013] Furthermore, the portion of the shaft located between the first support shaft end and the second support shaft end bends backward to form a support central shaft and forms a recessed area on the front side of the support central shaft.

[0014] Furthermore, the first support shaft end and the second support shaft end are coaxially arranged.

[0015] Furthermore, the elastic element is a helical compression spring.

[0016] Furthermore, the flexible roller sleeve is made of bendable fabric or elastic material.

[0017] Further, the first or second round group includes:

[0018] A first end cap is rotatably mounted on the first support shaft end or the second support shaft end, and an accommodating groove is provided at the outward end of the first end cap.

[0019] The second end cap is located on the side of the first end cap facing outward, so that by retracting one end of the flexible roller sleeve into the receiving groove and fastening the second end cap to the first end cap, one end of the flexible roller sleeve is fitted onto the first wheel set or the second wheel set.

[0020] Furthermore, a fixing component is provided on the shaft, and the shaft is detachably connected to the handle bracket through the fixing component.

[0021] Secondly, the technical solution of this utility model provides a novel tree trunk whitening roller brush, comprising:

[0022] Handle holder;

[0023] A shaft, which is connected to the handle bracket, the shaft including a first support shaft end and a second support shaft end opposite to each other;

[0024] A roller sleeve assembly includes a flexible roller sleeve and a first wheel group and a second wheel group arranged opposite to each other. The two ends of the flexible roller sleeve are respectively sleeved on the first wheel group and the second wheel group. The first wheel group is rotatably mounted on the end of a first support shaft, and the second wheel group is rotatably mounted on the end of a second support shaft. The flexible roller sleeve is made of a bendable elastic material.

[0025] Specifically, when the roller brush is in use, the outer surface of the flexible roller sleeve can be recessed inward, thereby placing the flexible roller sleeve in a bent state, and the elasticity of the flexible roller sleeve can allow it to be straightened.

[0026] As can be seen from the above technical solution, the novel tree trunk whitening roller brush of this utility model, by setting a handle bracket, provides a support structure for each component. The shaft is connected to the handle bracket and includes a first support shaft end and a second support shaft end that are opposite to each other. The roller sleeve assembly includes a flexible roller sleeve and a first wheel group and a second wheel group that are opposite to each other. The first wheel group is rotatably mounted on the first support shaft end, and the second wheel group is rotatably mounted on the second support shaft end. When the user holds the roller brush to brush the tree trunk or other columnar structure, the middle of the flexible roller sleeve is subjected to force, and the first wheel group and the second wheel group move towards each other. At this time, the flexible roller sleeve is in a bending state. In its bent state, the flexible roller sleeve conforms to the columnar structure of the plant trunk. The flexible roller sleeve effectively wraps around the plant trunk and provides efficient brushing. Furthermore, an elastic element is installed on the shaft. When the user is not using the roller brush, the elasticity of this element causes the first and second roller sets to move away from each other, thus returning the flexible roller sleeve to its straightened state. This design allows workers to brush a larger area of ​​the trunk during each up-and-down brushing application, improving work efficiency and coating quality, enhancing the worker's experience, simplifying operation, and reducing operational difficulty. Moreover, the roller brush structure is relatively simple, making it easy to manufacture and produce.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] In this utility model, for clearer description, the following explanation is provided: The observer faces the attached... Figure 1 When making observations, the left side of the observer is designated as left, the right side of the observer as right, the front of the observer as down, the back of the observer as up, the top of the observer as front, and the bottom of the observer as back. It should be noted that the terms "front end", "rear end", "left side", "right side", "middle", "above", "below" etc. in the text indicate the orientation or positional relationship based on the accompanying drawings. They are only for the purpose of clearly describing this utility model and do not indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] Please refer to the following: Figures 1 to 5 In a first aspect, Embodiment 1 provides a novel tree trunk whitening roller brush, comprising a handle bracket 100, a shaft 200, a roller sleeve assembly 300, and an elastic element 400. The shaft 200 is connected to the handle bracket 100 and includes opposing first support shaft ends 210 and second support shaft ends 220. The roller sleeve assembly 300 includes a flexible roller sleeve 310 and opposing first wheel sets 320 and second wheel sets 330. The two ends of the flexible roller sleeve 310 are respectively sleeved on the first wheel set 320 and the second wheel set 330. On the two-wheel assembly 330, the first wheel assembly 320 is rotatably mounted on the first support shaft end 210, and the second wheel assembly 330 is rotatably mounted on the second support shaft end 220. The elastic element 400 is disposed on the shaft 200. The first wheel assembly 320 and the second wheel assembly 330 can move towards each other to make the flexible roller sleeve 310 bend. Through the elastic action of the elastic element 400, the first wheel assembly 320 and the second wheel assembly 330 can move away from each other to make the flexible roller sleeve 310 straighten.

[0048] As can be seen, the novel tree trunk whitening roller brush of this utility model, by setting a handle bracket 100, provides a support structure for each component. The shaft 200 is connected to the handle bracket 100 and includes a first support shaft end 210 and a second support shaft end 220 facing each other. The roller sleeve assembly 300 includes a flexible roller sleeve 310 and a first wheel set 320 and a second wheel set 330 arranged opposite each other. The first wheel set 320 is rotatably mounted on the first support shaft end 210, and the second wheel set 330 is rotatably mounted on the second support shaft end 220. When the user holds the roller brush to brush a plant trunk or other columnar structure, the middle of the flexible roller sleeve 310 is subjected to force, causing the first wheel set 320 and the second wheel set 330 to move closer together. When the flexible roller sleeve 310 is in a bent state, it conforms to the columnar structure of the plant trunk. The flexible roller sleeve 310 can effectively wrap the plant trunk and perform efficient roller brushing. Furthermore, the shaft 200 is provided with an elastic element 400. When the user is not using the roller brush, the elasticity of the elastic element 400 can cause the first roller group 320 and the second roller group 330 to move away from each other, thereby returning the flexible roller sleeve 310 to a straight state. This design allows the worker to brush a larger area of ​​the tree trunk during each up and down roller brushing process, improving work efficiency and coating quality, enhancing the worker's user experience, facilitating operation, reducing operation difficulty, and the roller brush structure is relatively simple, making it easy to manufacture and produce.

[0049] Furthermore, such as Figures 1 to 5 As shown, the shaft 200 is composed of two separate strip structures, one of which is a first support shaft end 210 and the other is a second support shaft end 220. The handle bracket 100 has a first support arm 120 and a second support arm 130 arranged opposite to each other. The first support shaft end 210 is connected to the first support arm 120, and the second support shaft end 220 is connected to the second support arm 130.

[0050] The shaft 200 employs a separate two-strip structure, each connected to a different support arm of the handle bracket 100. This structure simplifies the connection between the components of the roller brush, allowing for easy assembly of the shaft 200 and handle bracket 100 during installation and quick disassembly, facilitating maintenance and component replacement. The separate shaft 200 structure also provides design flexibility, allowing for adjustments to the length and shape of the shaft 200 to meet various operational needs.

[0051] Furthermore, the first support shaft end 210 and the second support shaft end 220 are coaxially arranged. The coaxial arrangement can ensure that the first wheel group 320 and the second wheel group 330 are on the same axis, so that the flexible roller sleeve 310 is subjected to uniform force when rotating, and there will be no skewing or shaking. This ensures that the roller brush can roll smoothly on the tree trunk during the whitewashing process, improving the uniformity and quality of whitewashing.

[0052] In this embodiment, the elastic element 400 is a helical compression spring, and two elastic elements 400 are provided. The two elastic elements 400 are respectively installed on the first support shaft end 210 and the second support shaft end 220. A first abutment ring is formed at the inner end of the first support shaft end 210, and a second abutment ring is provided at the inner end of the second support shaft. One end of one elastic element 400 abuts against the first abutment ring and the other end of the elastic element 400 abuts against the first wheel assembly 320. One end of the other elastic element 400 abuts against the second abutment ring and the other end of the elastic element 400 abuts against the second wheel assembly 330.

[0053] Preferably, the flexible roller sleeve 310 is made of bendable fabric or elastic material. More preferably, it is made of plush fabric, which has a rich pile structure that can absorb a large amount of paint. During the painting process, the plush fabric can evenly release the paint, ensuring uniform coating on the tree trunk surface. The plush fabric is soft and can conform well to the irregular shape of the tree trunk surface, making close contact with both curved and uneven areas, ensuring that the paint covers all parts of the trunk, avoiding missed areas and improving painting quality. The pile of the plush fabric allows the paint to form a fine coating on the tree trunk surface, without brush marks or bubbles, resulting in a smoother and more even coating that is not only aesthetically pleasing but also enhances the protective effect of the paint on the tree trunk. Plush fabric is relatively easy to clean. After use, it can be washed with water or a suitable detergent to remove residual paint, facilitating future use. The performance of the plush fabric is not significantly affected after cleaning, maintaining a good painting effect.

[0054] In this embodiment, the first wheel assembly 320 or the second wheel assembly 330 includes a first end cap 321 and a second end cap 322. The first end cap 321 is rotatably mounted on the first support shaft end 210 or the second support shaft end 220. The outward end of the first end cap 321 is provided with a receiving groove 321a. The second end cap 322 is located on the outward side of the first end cap 321. By retracting one end of the flexible roller sleeve 310 into the receiving groove 321a and fastening the second end cap 322 onto the first end cap 321, one end of the flexible roller sleeve 310 is fitted onto the first wheel assembly 320 or the second wheel assembly 330.

[0055] The flexible roller sleeve 310 is well fixed by the friction between the second end cap 322 and the first end cap 321, and the flexible roller sleeve 310 will not easily fall off during use.

[0056] In one possible implementation, the flexible roller sleeve 310 is retracted into the receiving groove 321a, causing the opening of the flexible roller sleeve 310 to unfold against the bottom wall of the receiving groove 321a. The end of the second end cap 322 is inserted into the receiving groove 321a, so that the end of the second end cap 322 presses the annular opening of the flexible roller sleeve 310 against the bottom wall of the receiving groove 321a. At the same time, a first through hole is provided on the first end cap 321 and a second through hole is provided on the second end cap 322 corresponding to the first through hole. By passing a bolt through the first through hole and the second through hole in sequence, so that the end of the bolt protrudes from the second through hole, and a nut is screwed into the end of the bolt to fix the second end cap 322 relative to the first end cap 321, one end of the flexible roller sleeve 310 can be fixedly installed. The installation of the other end of the flexible roller sleeve 310 is the same. In this way, the flexible roller sleeve 310 will not easily fall off during use.

[0057] In another possible implementation, a slot is provided in the middle of the bottom wall of the receiving groove 321a, and a snap-fit ​​protrusion is provided in the middle of the end of the second end cover 322. By inserting the end of the second end cover 322 into the receiving groove 321a, the end of the second end cover 322 presses the annular opening of one end of the flexible roller sleeve 310 against the bottom wall of the receiving groove 321a. The snap-fit ​​protrusion is snapped into the slot, so that the second end cover 322 is fixed relative to the first end cover 321, and the annular opening of one end of the flexible roller sleeve 310 is fixedly installed between the second end cover 322 and the first end cover 321. In this way, the flexible roller sleeve 310 will not easily fall off during use.

[0058] In this embodiment, a fixing component 500 is provided on the shaft 200. The shaft 200 is detachably connected to the handle bracket 100 through the fixing component 500. The handle bracket 100 includes a frame 110 and opposing first support arms 120 and second support arms 130. Both the first support arms 120 and the second support arms 130 are provided with through holes 140. The first support shaft end 210 passes through the through hole 140 of the first support arm 120 and is inserted into the first support arm 120. The second support shaft end 220 passes through the through hole 140 of the second support arm 130 and is inserted into the second support arm 130. The outer peripheral surfaces of the first support shaft end 210 and the second support shaft end 220 are provided with external threads. Two sets of fixing components 500 are provided to fix the first support shaft end 210 and the second support shaft end 220 respectively. Each fixing component 500 includes a first nut 510 and a second nut 520, which are respectively located on both sides of the through hole 140. Tightening the first nut 510 and the second nut 520 causes them to move towards each other, thereby mounting the first support shaft end 210 or the second support shaft end 220 onto the handle bracket 100. When a component of the roller brush is damaged and needs replacement, since the shaft 200 is connected to the handle bracket 100 via nuts and threads, simply unscrewing the nuts allows the shaft 200 to be removed from the handle bracket 100, facilitating the replacement of the shaft 200 or other related components. This connection method facilitates product maintenance and repair, reduces maintenance costs, and extends the product's service life.

[0059] Please refer to the following: Figures 6 to 10 Example 2 provides a novel tree trunk whitening roller brush, which differs from Example 1 in that the shaft 200 is formed by bending a strip structure, and the first support shaft end 210 and / or the second support shaft end 220 of the shaft 200 are connected to the handle bracket 100.

[0060] Among them, the axle 200, which is formed by bending a strip structure, has good integrity and continuity, and can provide strong support. During use, it can better bear the weight of the roller sleeve assembly 300 and various forces generated during the whitening process, ensuring that the axle 200 will not easily deform or break, thereby ensuring the structural strength and stability of the entire tree trunk whitening roller brush.

[0061] In the second embodiment, the portion of the shaft 200 located between the first support shaft end 210 and the second support shaft end 220 is bent backward to form a support central shaft 230 and a recessed area 240 is formed on the front side of the support central shaft 230.

[0062] The recessed area 240 provides bending deformation space for the flexible roller sleeve 310, allowing it to better conform to the curved surface of the tree trunk. This increases the area the flexible roller sleeve 310 covers while brushing the trunk, and also ensures closer contact between the flexible roller sleeve 310 and the trunk surface, thereby improving the brushing effect and enabling more even application of paint to the trunk, reducing missed areas or uneven application. The supporting central shaft 230 provides additional support for the flexible roller sleeve 310. During roller brush operation, especially when the flexible roller sleeve 310 is in a bent state while brushing the tree trunk, it enhances the stability of the flexible roller sleeve 310, preventing excessive deformation or shaking, and ensuring the reliability and durability of the roller brush during use.

[0063] According to the first aspect, this application also provides a novel tree trunk whitening roller brush, including a handle bracket 100, a shaft 200, and a roller sleeve assembly 300. The shaft 200 is connected to the handle bracket 100 and includes a first support shaft end 210 and a second support shaft end 220 opposite to each other. The roller sleeve assembly 300 includes a flexible roller sleeve 310 and a first wheel group 320 and a second wheel group 330 arranged opposite to each other. The two ends of the flexible roller sleeve 310 are respectively sleeved on the first wheel group 320 and the second wheel group 330. The first wheel group 320 is rotatably mounted on the first support shaft end 210, and the second wheel group 330 is rotatably mounted on the second support shaft end 220. The flexible roller sleeve 310 is made of a bendable elastic material so that when the roller brush is in use, the outer surface of the flexible roller sleeve 310 can be concave inward, thereby putting the flexible roller sleeve 310 in a bent state, so that the flexible roller sleeve 310 can be straightened through the elastic action of the flexible roller sleeve 310.

[0064] The flexible roller sleeve 310 is made of a bendable elastic material. During use, it automatically bends inward to conform to the shape of the tree trunk, closely fitting the surface and ensuring a more even whitening process. This prevents missed areas or inconsistent paint thickness, improving the whitening effect and quality. Because the flexible roller sleeve 310 can quickly adapt to the shape of the tree trunk and automatically recover, the whitening process can be performed more smoothly, reducing time wasted adjusting the fit between the tool and the trunk, thus improving work efficiency and saving labor and time costs.

[0065] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0066] By setting a handle bracket 100, the handle bracket 100 provides a support structure for each component. The shaft 200 is connected to the handle bracket 100 and includes a first support shaft end 210 and a second support shaft end 220 facing each other. The roller sleeve assembly 300 includes a flexible roller sleeve 310 and a first wheel set 320 and a second wheel set 330 arranged opposite each other. The first wheel set 320 is rotatably mounted on the first support shaft end 210, and the second wheel set 330 is rotatably mounted on the second support shaft end 220. When the user holds the roller brush to brush the plant trunk or other columnar structure, the middle of the flexible roller sleeve 310 is subjected to force, and the first wheel set 320 and the second wheel set 330 move towards each other. At this time, the flexible roller sleeve 310 is in a position where... In its bent state, the flexible roller sleeve 310 conforms to the columnar structure of the plant trunk. The flexible roller sleeve 310 can effectively wrap the plant trunk and perform efficient roller brushing. Furthermore, the shaft 200 is equipped with an elastic element 400. When the user is not using the roller brush, the elasticity of the elastic element 400 can cause the first roller group 320 and the second roller group 330 to move away from each other, thereby returning the flexible roller sleeve 310 to the straightened state. This design allows the worker to brush a larger area of ​​the trunk during each up and down roller brushing process, improving work efficiency and coating quality, enhancing the worker's user experience, facilitating operation, reducing operation difficulty, and the roller brush structure is relatively simple, making it easy to manufacture and produce.
