Coating device for interior decoration

Abstract

This utility model provides a coating device for interior decoration, including a rod body. A roller brush assembly is connected to the end of the rod body. The roller brush assembly includes two support arms connected to the end of the rod body. A main roller rolls between the two support arms, and a secondary roller rolls below the main roller. A protective cover connected to the support arms is fitted to the outer side of the main roller. A secondary arm is fixed to the outer wall of each support arm, and the secondary roller is rotatably connected between the two sets of secondary arms. Both ends of the secondary roller are connected to the secondary arms via locking handles. This embodiment collects paint overflowing from the main roller and dripping downwards through the secondary roller, which is then applied to the wall as the main roller rolls. The protective cover collects paint splashed from the main roller due to centrifugal force and conveys it to the secondary roller for application to the wall, reducing paint waste and lowering costs.

Description

Technical Field

[0001] This utility model relates to the field of decoration technology, and in particular to a coating device for interior decoration. Background Technology

[0002] As an important piece of construction equipment, roller brushes are mainly used for applying paint in daily building decoration. With the extension rod attached, they can be used to paint walls and ceilings, so roller brushes have a wide range of applications.

[0003] When painting walls with a roller brush, the roller rolls against the wall, and the centrifugal force causes the paint on the roller to splash away from the wall, potentially hitting the painter. Furthermore, the contact between the roller brush and the wall creates a squeezing effect, causing the paint adsorbed by the brush to flow down the wall, resulting in paint waste.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all 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 protection scope of this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Please see Figures 1 to 4 The interior decoration coating device of this utility model includes a rod 100, and a roller brush assembly 110 is connected to the end of the rod 100. The roller brush assembly 110 includes two support arms 111 connected to the end of the rod 100. A main roller 130 is rolled between the two support arms 111, and a secondary roller 150 is rolled between the two support arms 111 below the main roller 130. A protective cover 120 connected to the outer wall of the support arms 111 is fitted to the outer side of the main roller 130. A guide plate 121 for guiding the coating to the outer wall of the secondary roller 150 is fixed to the bottom of the protective cover 120. The protective cover 120 and the guide plate 121 can be integrally formed, and the inner wall of the protective cover 120 is inclined towards the secondary roller 150.

[0031] A pair of lugs are fixed to both sides of the protective cover 120, and the lugs are fixedly connected to the support arm 111 by screws. In this way, the protective cover 120 and the support arm 111 can be disassembled, which facilitates the cleaning of residual paint inside the protective cover 120.

[0032] Each support arm 111 has a secondary arm 140 fixed to its outer wall. A secondary roller 150 is rotatably connected between the two secondary arms 140. The two ends of the secondary roller 150 are connected to the secondary arms 140 by means of a locking handle 112. The locking handle 112 can be a bolt with a knob.

[0033] like Figure 2 As shown, the included angle between the rod body 100 and the lower part of the roller brush assembly 110 ( Figure 2 The angle (in the direction of the middle) is obtuse. When a person holds the rod 100 to paint the wall, both the main roller 130 and the auxiliary roller 150 are in contact with the wall. When the main roller 130 contacts the wall and creates a squeezing effect, the paint overflowing from the main roller 130 will flow downwards, dripping down along the wall or parallel to the wall. At this time, the auxiliary roller 150 can coat the dripping paint onto the wall, thereby reducing the amount of paint dripping onto the ground.

[0034] When the main roller 130 rotates, it generates a certain centrifugal force, which causes the paint to splash outwards. The protective cover 120 blocks the splashed paint and directs it to the auxiliary roller 150 via the guide plate 121. When the auxiliary roller 150 rotates, it can cover the wall with paint, further reducing paint waste.

[0035] Please see Figure 1 , Figure 2 and Figure 4 The rod body 100 is composed of multiple sets of cylindrical rods 101 and fastening bolts 102. The multiple sets of cylindrical rods 101 are sleeved together to form a multi-stage telescopic rod, and two sleeved cylindrical rods 101 are locked together by fastening bolts 102. The outer wall of the lowest cylindrical rod 101 is covered with an anti-slip sleeve 103, which is made of anti-slip rubber material.

[0036] When applying wall coatings at different heights, the fastening bolts 102 can be loosened, and multiple sets of cylindrical rods 101 can be pulled outwards or retracted inwards to control the total length of the rods 100 and meet the coating requirements at different heights.

[0037] During operation, personnel can hold the anti-slip sleeve 103 to control the rod 100 to apply paint to the wall.

[0038] Please see Figure 1 and Figure 2The rod 100 has a connecting shaft welded to its end, and both ends of the connecting shaft are detachably connected to the two support arms 111 using locking bolts. Loosening the locking bolts can release the lock between the support arms 111 and the connecting shaft, allowing adjustment of the angle between the rod 100 and the two support arms 111, thereby enabling painting work on walls or ceilings and improving the flexibility of the device.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
