Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to an edge and corner coating equipment. Background Technology

[0002] In painting operations, there are various types of coating equipment. Wall rollers are a common type of coating equipment, frequently used in painting walls and coating regular objects.

[0003] Applying paint to corners and edges has always been a challenge in wall painting with a roller. A wall painting roller is a straight, cylindrical brush that picks up paint and then contacts the wall or other regular surface to be coated. However, applying paint to transitional areas with a typical wall painting roller is not convenient, such as... Figure 5 As shown, at the interface transition, a typical wall paint roller can only coat one side of the wall at a time. For buildings with many interface transitions, coating requires two operations each time, which increases the working time.

[0004] To address this, an edge coating device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an edge coating device, which aims to improve the problem that in the traditional coating process, a typical wall roller can only coat one side of the wall at a time. This application is based on the working state of the bidirectional roller forming a right angle, which facilitates direct coating of the wall corner, effectively improving the coating efficiency of the workers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An edge coating device includes a mounting sleeve, the mounting sleeve comprising a plurality of mounting cylinders, the axes of the plurality of mounting cylinders being located on the same horizontal plane, and the mounting cylinders being threaded sleeves that pass through the object.

[0008] It also includes a main roller brush, a secondary roller brush, and a telescopic rod that are movably connected to the mounting sleeve, and the corner coating device is provided in a first form and a second form;

[0009] In the first state, the main roller brush is fixedly connected to the mounting sleeve, and the main roller brush is fixedly connected to the telescopic rod;

[0010] In the second configuration, the main roller brush is fixedly connected to the mounting sleeve, the auxiliary roller brush is fixedly connected to the mounting sleeve, and the main roller brush is fixedly connected to the telescopic rod. The axis of the main roller brush and the axis of the auxiliary roller brush are located in the same plane, and the included angle formed by the axis of the main roller brush and the axis of the auxiliary roller brush is equal to the included angle of the wall surface to be coated.

[0011] Preferably, in the second configuration, the axis of the main roller brush and the axis of the auxiliary roller brush form a right angle.

[0012] Preferably, a limiting mechanism is provided at the upper end of the outer wall of the telescopic rod, the limiting mechanism including a limiting spring pin fixedly disposed on the telescopic rod and a limiting tube fixedly disposed on the auxiliary roller brush.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when a worker needs to coat a single wall surface, after holding the telescopic rod and getting the main roller brush full of paint, the main roller brush will rotate around the internal roller shaft to complete the painting work of the single wall surface. When the roller brush needs to be replaced, the main roller brush can be unscrewed from the mounting sleeve to replace the main roller brush. When the handle length is insufficient, the telescopic rod can be pulled down to increase the length of the rod body, and vice versa. When the handle length is too long, the length of the telescopic rod body can be shortened to better complete the coating work.

[0015] 2. In this utility model, when workers need to coat a single wall surface, they only need to follow certain coating operations;

[0016] When workers need to coat the corners of a wall, they rotate the secondary roller brush onto the mounting sleeve and simultaneously change the position of the telescopic rod on the mounting sleeve so that the telescopic rod is on the axis of symmetry between the main and secondary roller brushes. At this point, the axes of the main and secondary roller brushes are on the same horizontal plane, and the angle between them is the same as the angle between them and the wall. When coating the corners of a wall, both sides can be coated at once, which is convenient for operation. Attached Figure Description

[0028] 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.

[0029] Reference Figure 1 , 2 5. An edge coating device, comprising a mounting sleeve 1, wherein the mounting sleeve 1 comprises a plurality of mounting cylinders, the axes of the plurality of mounting cylinders are all located on the same horizontal plane, the mounting cylinders are through threaded sleeves, and the plurality of mounting cylinders form a plurality of openings;

[0030] It also includes a main roller brush 3, a secondary roller brush 4 and a telescopic rod 5 that are movably connected to the mounting sleeve 1, and the corner coating equipment is provided in a first form and a second form;

[0031] In the first state, the main roller brush 3 is fixedly connected to the mounting sleeve 1, and the main roller brush 3 is fixedly connected to the telescopic rod 5;

[0032] In the second configuration, the main roller brush 3 is fixedly connected to the mounting sleeve 1, the auxiliary roller brush 4 is fixedly connected to the mounting sleeve 1, the main roller brush 3 is fixedly connected to the telescopic rod 5, the axis of the main roller brush 3 and the axis of the auxiliary roller brush 4 are located in the same plane, and the included angle formed by the axis of the main roller brush 3 and the axis of the auxiliary roller brush 4 is equal to the included angle of the wall surface to be coated.

[0033] In the second configuration, the axis of the main roller brush 3 and the axis of the auxiliary roller brush 4 form a right angle.

[0034] The upper end of the outer wall of the telescopic rod 5 is provided with a limiting mechanism 2, which includes a limiting spring pin 21 fixedly mounted on the telescopic rod 5 and a limiting tube fixedly mounted on the auxiliary roller brush 4.

[0035] Example 1

[0036] Reference Figure 1 , 3As shown in Figure 4, this embodiment is used for general painting of a single wall surface. The main roller brush 3 is connected to any opening of the mounting sleeve 1, thereby achieving a fixed connection between the mounting sleeve 1 and the main roller brush 3. Then, the telescopic rod 5 is fixedly connected to any opening of the mounting sleeve 1.

[0037] It should be noted that the axes of the telescopic rod 5 and the main roller brush 3 are perpendicular. When the operator holds the telescopic rod 5, the main roller brush 3, which is dipped in paint, can be rolled up and down to achieve vertical movement of the axis of the main roller brush 3.

[0038] Example 2

[0039] Reference Figure 2 , 3 As shown in Figure 4, this embodiment is used for painting two wall surfaces. The main roller brush 3 is connected to any opening of the mounting sleeve 1, thereby achieving a fixed connection between the mounting sleeve 1 and the main roller brush 3. Then, the telescopic rod 5 is fixedly connected to any opening of the mounting sleeve 1, and the auxiliary roller brush 4 is connected to other openings of the mounting sleeve 1, thereby achieving a fixed connection between the mounting sleeve 1 and the auxiliary roller brush 4. Then, the telescopic rod 5 is fixedly connected to other openings of the mounting sleeve 1.

[0040] The upper end of the outer wall of the telescopic rod 5 is provided with a limiting mechanism. The limiting mechanism 2 includes a limiting spring pin 21 fixedly installed on the telescopic rod 5 and a limiting tube 22 fixedly installed on the secondary roller brush 4, which is used to limit the secondary roller brush 4 so that the axis of the secondary roller brush 4 and the axis of the main roller brush 3 are located in the same plane.

[0041] It is important to note that when installing the secondary roller brush 4 and the telescopic rod 5, attention should be paid to the installation interface. There is an angle between the axis of the main roller brush 3 and the axis of the secondary roller brush 4. This angle is equal to the angle formed by the wall surface to be painted, so that the main roller brush 3 and the secondary roller brush 4 can fit against the wall surface to be painted when they are working.

[0042] For ease of operation, the axis of the telescopic rod 5 needs to be on the axis of symmetry of the axis of the main roller brush 3 and the axis of the auxiliary roller brush 4. They can coincide or be parallel, which facilitates the application of force during coating.

[0043] Reference Figure 5 When the worker holds the telescopic rod 5, the axis of the main roller brush 3 and the auxiliary roller brush 4, which are dipped in paint, can be rolled up and down, so as to achieve vertical movement of the axis of the main roller brush 3 and the axis of the auxiliary roller brush 4, thereby coating two walls at the same time.

[0044] Working principle: First, connect the main roller brush 3 to the opening of the mounting sleeve 1, and connect the auxiliary roller brush 4 to the other opening. Fix them with threads to ensure that the angle between the axis of the main roller brush 3 and the axis of the auxiliary roller brush 4 is equal to the angle of the wall to be painted, and that the two axes are coplanar.

[0045] Next, connect the telescopic rod 5 to the third opening of the mounting sleeve 1, and adjust the installation position so that the axis of the telescopic rod 5 is on the axis of symmetry of the axis of the main roller brush 3 and the axis of the auxiliary roller brush 4. They can coincide or be parallel, ensuring that the direction of force exerted by the staff when holding it is consistent with the coating requirements of the two walls.

[0046] Finally, the limiting mechanism 2 locks the position: the limiting pin 21 engages with the limiting tube of the auxiliary roller brush 4, fixing the relative position of the auxiliary roller brush and the telescopic rod to prevent angular deviation during operation; the operator holds the telescopic rod 5, dips the surfaces of the main and auxiliary roller brushes in paint at the same time, and applies them to the two intersecting wall surfaces respectively; the telescopic rod 5 is moved vertically, so that the main roller brush 3 and the auxiliary roller brush 4 roll synchronously around their own axis, and the two rollers are tightly attached to the corresponding wall surfaces respectively. When rolling, the paint is evenly applied to the wall surface, realizing the coating of the two wall angles in one operation.

[0047] 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.
