[0002] In numerous fields such as architectural decoration and industrial protection, the spraying of waterproof coatings is a crucial task, directly affecting the waterproof performance and lifespan of buildings or equipment. With technological advancements, various mechanized spraying tools have emerged, improving spraying efficiency and quality to some extent. However, many existing spraying tools still have shortcomings. For example, during the spraying process, the angle adjustment of the nozzle is not flexible and convenient enough, making it difficult to precisely adjust according to different spraying positions and needs, resulting in unsatisfactory spraying effects and failing to meet diverse spraying requirements.

The protective device includes a disc, the disc is fixedly connected to the arc surface of the nozzle, and two first mounting rods are fixedly connected to the arc surface of the disc.

[0004] However, the device still has the following drawbacks:

[0005] When using this device, the nozzle angle is inconvenient to adjust and it cannot quickly adapt to different spraying surfaces (such as walls, ceilings, curved surfaces, etc.). It requires repeated adjustments to the equipment position or manual intervention, which leads to longer spraying time and reduced efficiency. Therefore, we need to propose a waterproof coating spraying tool with a rotatable nozzle. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] Waterproof coating spraying tools with rotatable nozzles include:

[0029] A transfer cart 1 with a handle on one side, a paint tank 2 at the top of the transfer cart 1, a paint nozzle 8 on one side of the paint tank 2, and a rotating component 9 for adjusting the angle of the paint nozzle 8 on the outside of the paint tank 2.

[0030] The paint tank 2 is equipped with a liquid level display component 10 for easy observation of the liquid level inside the paint tank 2.

[0031] The rotating assembly 9 includes a U-shaped frame 91, a rotating rod 92, a connecting plate 93, a through hole 94, a limiting bolt 95, and a threaded hole 96;

[0032] The paint tank 2 has a U-shaped frame 91 fixedly connected to its side wall. Two symmetrically distributed rotating rods 92 are rotatably connected inside the U-shaped frame 91. The two rotating rods 92 are fixedly connected to the paint nozzles 8. A connecting plate 93 is fixedly connected to the side wall of one of the rotating rods 92. Two symmetrically distributed through holes 94 are opened inside the connecting plate 93. Limit bolts 95 are installed inside the two through holes 94. Multiple threaded holes 96 are arranged in a ring on the side wall of the U-shaped frame 91. The two threaded holes 96 are threadedly connected to the two limit bolts 95 respectively.

[0033] For example, the paint nozzle 8 is installed by rotating rod 92. The angle of the paint nozzle 8 is adjusted by controlling the angle of connecting plate 93. The through hole 94 facilitates the passing of the limiting bolt 95 through the connecting plate 93. The limiting bolt 95 cooperates with the threaded hole 96 to fix the connecting plate 93. Multiple threaded holes 96 at different angles facilitate fixing the connecting plate 93 at different angles.

[0034] The U-shaped frame 91 is rotatably connected to the paint spray head 8 and the connecting plate 93 respectively.

[0035] For example, the U-shaped frame 91 limits the paint nozzle 8.

[0036] The liquid level display component 10 includes a transparent strip 101, a cleaning block 102, a slide bar 103, a limit plate 104, and scale lines 105;

[0037] The paint tank 2 has a transparent strip 101 fixedly connected to the inside of its side wall, a cleaning block 102 slidably connected to the outside of the transparent strip 101, a slide rod 103 fixedly connected to the upper end of the cleaning block 102, a limit plate 104 fixedly connected to the upper end of the slide rod 103, and a scale line 105 provided on the outside of the slide rod 103.

[0038] For example, the transparent strip 101 facilitates observation of the liquid level inside the paint tank 2. The cleaning block 102 cleans the side of the transparent strip 101 located inside the paint tank 2 to prevent paint from adhering to the transparent strip 101 and affecting the accuracy of observation. The sliding rod 103 is used to install the cleaning block 102. The limiting plate 104 prevents the sliding rod 103 from falling into the paint tank 2 and facilitates the raising and lowering of the sliding rod 103. The design of the scale line 105 facilitates observation of the height of the sliding rod 103 as it descends, thereby understanding the height of the liquid level inside the paint tank 2.

[0039] The upper end of the paint box 2 is provided with a box cover 3, which is slidably connected to the slide rod 103.

[0040] For example, the lid 3 seals the paint tank 2 and the lid 3 is also installed on the slide bar 103. The inside of the lid 3 is provided with a feed pipe 4, through which paint can be easily injected into the inside of the paint tank 2.

[0041] The paint tank 2 is equipped with a water pump 5. A connecting pipe 6 is fixedly connected to the outlet pipe of the water pump 5. A flexible hose 7 is installed at the upper end of the connecting pipe 6. One end of the flexible hose 7 is fixedly connected to the paint nozzle 8.

[0042] For example, the water pump 5 provides power for removing the paint from the paint tank 2, the connecting pipe 6 and the hose 7 transport the paint, the connecting ends of the connecting pipe 6 and the hose 7 are both provided with threads on the outside, the connecting pipe 6 and the hose 7 are connected by an internal threaded disc, and the flexible design of the hose 7 facilitates the rotation of the paint nozzle 8. The recommended model of the water pump 5 is the JET-550G diaphragm pump.

[0043] Working principle: Before use, the paint is injected into the paint tank 2 through the feed pipe 4. The slide bar 103 and the cleaning block 102 are lifted by the limit plate 104. The cleaning block 102 cleans the side wall of the transparent strip 101, observes the scale line 105, and observes the liquid level inside the paint tank 2 to avoid adding too much paint. Similarly, when using, the amount of paint remaining inside the paint tank 2 can be observed.

[0044] When in use, move the transfer cart 1 to a suitable position. First, adjust the angle of the paint nozzle 8 according to the spraying position. Loosen the limit bolt 95 to release the limit on the connecting plate 93. The connecting plate 93 drives the rotating rod 92 to rotate, adjusting the angle between the paint nozzle 8 and the U-shaped frame 91. Use the limit bolt 95 and the threaded holes 96 at different positions to position the connecting plate 93 and the paint nozzle 8. Then turn on the water pump 5, which draws out the paint. The paint enters the paint nozzle 8 through the connecting pipe 6 and the hose 7, and the paint nozzle 8 performs the spraying work.

[0045] The water pump 5 in this application is controlled automatically by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail. The device is powered by a built-in power supply or an external power supply.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
