Description

Technical Field

[0001] The utility model relates to the technical field of coating construction devices, in particular to a coating construction device for building exterior walls. Background Art

[0002] During the process of building decoration, it is often necessary to paint the exterior walls, and traditional painting work mostly uses a roller brush. Announcement No. CN 215760249U discloses an exterior wall paint construction device, which includes a telescopic rod, a connecting rod, a roller and a roller brush, an adjustment structure and a splash guard, wherein a handle is fixedly installed on the telescopic rod; one end of the connecting rod is installed on the telescopic rod, and the other end of the connecting rod is installed with a roller and is rotatably connected to the roller, one end of the roller is provided with an annular threaded groove, and the other end of the roller is provided with a threaded hole and a limit groove; the roller brush is sleeved on the roller, and one end of the roller brush is fixed to the roller by a sealing plug, and the other end of the roller brush is fixed to the roller by a fixing member; the adjustment structure is installed on the connecting rod; and the splash guard is installed on the connecting rod through the adjustment structure.

[0003] The exterior wall paint construction device in the above-mentioned prior art has the following problems during use: when using the existing roller brush, the roller brush is usually first inserted into the paint bucket so that the roller brush is covered with paint, and then the roller brush is placed vertically, the push rod is held and the roller brush is swung up and down, so that excess paint on the roller brush falls into the paint bucket, avoiding excess paint on the roller brush falling on the ground when the roller brush is taken out, preventing the paint dropped on the ground from causing trouble for subsequent cleaning, and also avoiding waste of paint. However, in this method, after the roller brush is covered with paint each time, it is necessary to swing the roller brush up and down by holding the push rod, and the roller brush covered with paint and the push rod together have a certain weight. The reciprocating up and down swinging requires a lot of physical strength, and part of the paint on the roller brush will overflow from the top of the paint bucket during the up and down swing, which will also cause waste and cause trouble for subsequent cleaning. Utility Model Content

[0004] (1) Purpose of the utility model

[0021] Reference Figure 1-3 :

[0022] In one embodiment of the present invention, a construction exterior wall coating construction device is provided, comprising a main unit 100 and an installation unit 200. The main unit 100 comprises a mounting rod 101, a mounting block 102 is fixed to the bottom of the mounting rod 101, a push rod 103 is threadedly connected to the bottom of the mounting block 102, a connecting pipe 104 is fixed inside the mounting rod 101, a cylindrical rod 105 is slidably connected to the connecting pipe 104, a plurality of guide grooves 207 are opened in the connecting pipe 104, a plurality of guide blocks 208 are fixed to the outside of the cylindrical rod 105, the guide blocks 208 are slidably fitted in the corresponding guide grooves 207, and the cylindrical rod 105 is fixed to the outside of the cylindrical rod 105. An inner cylinder 106 is provided on the side, and the inner wall diameter of the inner cylinder 106 is larger than the diameter of the cylindrical rod 105. The inner cylinder 106 can slide on the cylindrical rod 105 and can rotate outside the cylindrical rod 105. A roller brush 107 is fixed on the outside of the inner cylinder 106, and the mounting unit 200 includes a limiting plate 201, which is fixed on the cylindrical rod 105. The end of the cylindrical rod 105 away from the limiting plate 201 is threadedly connected with a retaining ring 202. The outer ring diameters of the limiting plate 201 and the retaining ring 202 are both larger than the outer ring diameter of the inner cylinder 106. A vibration component for shaking off excess paint on the roller brush 107 is provided on the mounting rod 101.

[0023] It should be noted that when replacing the roller brush 107, first rotate the retaining ring 202 to remove it from the cylindrical rod 105, and then the roller brush 107 and the inner cylinder 106 can be removed from the cylindrical rod 105. In addition, due to the setting of the guide block 208 and the guide groove 207, the cylindrical rod 105 can move stably in the connecting tube 104.

[0024] Among them, the vibration assembly includes a plurality of protrusions 203 fixed on one side of the mounting rod 101, a traction rope 204 is fixed at one end of the cylindrical rod 105, the traction rope 204 passes through the connecting tube 104 and the protrusion 203 and slides in the connecting tube 104 and the protrusion 203, a pull ring 205 is fixed at one end of the traction rope 204 away from the cylindrical rod 105, a spring 206 is provided in the connecting tube 104, the traction rope 204 is located in the spring 206, and one end of the spring 206 is fixed to the cylindrical rod 105, and the other end of the spring 206 is fixed to the inner wall of the connecting tube 104.

[0025] When in use, hold the push rod 103 and extend the roller brush 107 into the paint bucket so that the roller brush 107 is covered with paint, then lift the push rod 103 to remove the roller brush 107 from the paint, and then rotate the push rod 103 to rotate the roller brush 107 to a vertical state, and make the connecting tube 104 located above the roller brush 107, at this time, place the mounting rod 101 on the paint bucket so that the roller brush 107 is located in the paint bucket, and then pull the pull ring 205 so that the pull ring 205 pulls the cylindrical rod 105 through the traction rope 204, so that the cylindrical rod 105 moves into the connecting tube 104 and compresses the spring 206, and then releases the roller brush 107. Open the pull ring 205. At this time, under the rebound force of the spring 206, the cylindrical rod 105 moves downward, causing the guide block 208 to hit the connecting tube 104, thereby causing the cylindrical rod 105 and the roller brush 107 to vibrate. When the roller brush 107 vibrates, the excess paint on the roller brush 107 falls into the paint bucket. In this way, by placing the mounting rod 101 on the paint bucket, only the pull ring 205 needs to be pulled, and there is no need to swing the mounting rod 101 and the roller brush 107 up and down, which is more labor-saving. In addition, the roller brush 107 is located in the paint bucket, which avoids excess paint overflowing from the paint bucket compared to swinging the roller brush 107.

[0026] The exemplary implementation schemes proposed in the present disclosure are described in detail above with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
