Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a spray painting tool for building construction. Background Technology

[0002] Interior decoration serves people's social activities and living needs, and painting equipment is often used in this process. Most existing interior wall painting equipment uses airless sprayers. These sprayers utilize a plunger pump to pressurize the paint, delivering the high-pressure paint through a high-pressure hose to the spray gun. The pressure is then released through the nozzle, atomizing the paint and forming a dense coating on the wall surface. While existing spraying equipment meets the needs of decoration to a certain extent, it still has some shortcomings. For example, the length of the high-pressure hose in existing airless sprayers cannot be adjusted according to requirements, causing the hose to be pulled to the ground during spraying. This leads to wear and tear on the hose due to friction, and paint and stains adhere to the surface of the hose, thus affecting its lifespan.

[0003] The patent document with application number 202221371045.6 discloses an efficient environmentally friendly spray painting device for building decoration. When moving, the high-pressure hose can be stored inside the storage cylinder by coiling it on the surface of the support column. At this time, the high-pressure hose is limited by the adhesion of the female and male sides of the hook and loop fastener. When in use, the female side of the hook and loop fastener is pulled out to pull out the appropriate length of high-pressure hose as needed. Then, the female and male sides of the hook and loop fastener are glued together to limit the remaining high-pressure hose inside the storage cylinder. Although this spray painting device solves the problem of wear and contamination of the hose, the hook and loop fastener needs to be operated every time the hose is extended or retracted. Because the working environment of the spray painting device is relatively harsh, the hook and loop fastener will lose its adhesive effect after repeated use due to contamination, resulting in the loss of adjustment function. Utility Model Content

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-8 As shown, the building construction spraying tools include a trolley 1, a sprayer 2, a hose and a nozzle, and a storage tray 3 set at the bottom of the trolley 1 for storing the hose.

[0028] The storage tray 3 includes two upright plates 31 at the bottom of the trolley 1, a rotating shaft 32 connected to the two upright plates 31, an adapter 4 on the rotating shaft 32, and a drive mechanism 33 connected to the rotating shaft 32 on one side of the upright plate 31 for driving the rotating shaft 32 to rotate. A flexible hose is wound around the rotating shaft 32 and connected to the discharge end of the adapter 4. The feed end of the adapter 4 is connected to the discharge port of the sprayer 2 through a pipe.

[0029] In this embodiment, the drive mechanism 33 is a handwheel, which includes a wheel and a handle, and the handle can be folded relative to the wheel. The rotating shaft 32 is cylindrical and is rotatably connected between the two upright plates 31, with one end of the rotating shaft 32 connected to the handwheel.

[0030] This building construction spray painting tool includes a storage tray 3 and an adapter 4 installed on the rotating shaft 32 of the storage tray 3, with one end connected to a flexible hose and the other end connected to the outlet of the sprayer 2. Under the action of the drive mechanism 33, the flexible hose wound on the rotating shaft 32 can be scaled up or down to adjust the length of the hose, thereby preventing friction with the ground due to excessively long high-pressure hoses. Furthermore, the high-pressure hose can be wound up and stored during movement, making it convenient for workers to organize the high-pressure hose and preventing wear and contamination. In addition, compared with other storage methods, the storage tray 3 does not require the cleanliness of the entire surface of the hose, and the winding and scaling are not affected in any way, making it suitable for harsh spray painting environments and more versatile.

[0031] The storage tray 3 has a base 12 at its lower part. The base 12 includes a horizontal plate connected to the lower end of the upright plate 31. A bracket 11 is provided on one side of the horizontal plate, and the flexible hose extends or retracts through the bracket 11.

[0032] The bracket 11 is provided with a buckle 5; the buckle 5 includes a lower half tile 52 and an upper half tile 51, one end of the upper half tile 51 is hinged to the lower half tile 52, and the other end is provided with a fixing component.

[0033] The inner wall of the upper half tile 51 is provided with a sponge pad; the fixing assembly includes magnetic suction pieces correspondingly disposed at the ends of the upper half tile 51 and the lower half tile 52.

[0034] A storage groove is provided on the rotating shaft 32, and the adapter 4 is L-shaped and partially located in the storage groove. In this embodiment, the adapter 4 includes a straight pipe section 41 and a bent pipe section 42. The straight pipe section 41 passes through the upright plate 31, and one end of the straight pipe section 41 is provided with a first connecting end 411. One end of the bent pipe section 42 is provided with a connector seat 421 rotatably connected to the first connecting end 411, and the other end is provided with a second connecting end 422 for connecting a flexible hose. Specifically, the straight pipe section 41 is fixedly connected to the upright plate 31 and the first connecting end 411 is inserted into the storage groove. The connector seat 421 of the bent pipe section 42 is rotatably connected to the first connecting end 411, and the second connecting end 422 is located in the storage groove for connecting a flexible hose.

[0035] The first connecting end 411 has a trapezoidal cross section. The connector seat 421 includes a receiving part for receiving the first connecting end 411. A flange 43 is provided on the outer side of the receiving part, and a sealing ring 44 is provided on the inner side of the flange 43. The sealing ring 44 presses against the flange 43 and the first connecting end 411.

[0036] When making the connection, the other end of the first connecting end 411 of the straight pipe section 41 is connected to the pipe, which is directly connected to the outlet of the sprayer 2, while the second connecting end 422 is connected to the hose. Since the first connecting end 411 and the connector seat 421 are rotatably connected, the bent pipe section 42 will rotate when the rotating shaft 32 is rotated, thereby realizing the expansion and contraction of the hose.
