[0046] The present utility model first provides a waterproof coating application device.

[0047] In one embodiment, referring to the attached Figure 1 to the attached Figure 3 as shown, the waterproof coating application device includes:

[0048] Trolley 1;

[0049] Coating supply assembly 2, including a coating tank 21 and a water pump 22 both arranged on the trolley 1, and the input end of the water pump 22 is connected to the coating tank 21;

[0050] The roller brush assembly 3 includes a hand-held rod 31, a rotating frame 32, a roller brush 33, a scraper 34, a spray head 35 and a locking member 36. The rotating frame 32 is rotatably arranged at the first end of the hand-held rod 31. The scraper 34 and the spray head 35 are both fixedly arranged on the rotating frame 32. The roller brush 33 is rotatably arranged on the rotating frame 32. The scraper 34 and the roller brush 33 are respectively arranged at intervals on both sides of the rotation axis of the rotating frame 32. The spray head 35 is arranged facing the roller brush 33 and is connected to the output end of the water pump 22. The locking member 36 is used to lock or unlock the rotating frame 32 and the hand-held rod 31.

[0051] In the waterproof coating applying device of this embodiment, the roller brush 33, the scraper 34 and the spray head 35 are all arranged on the rotating frame 32. The rotating frame 32 is rotatably arranged at the first end of the hand-held rod 31 and can be locked or unlocked by the locking member 36. With such an arrangement, when the locking member 36 is unlocked, the rotating frame 32 can rotate relative to the hand-held rod 31 to adjust the positions of the roller brush 33 and the scraper 34. When the locking member 36 is locked, the rotating frame 32 is fixed relative to the hand-held rod 31 to keep the positions of the roller brush 33 and the scraper 34. In this way, during the actual operation, the operator can adjust the positions of the roller brush 33 and the scraper 34 according to the operation requirements to apply the waterproof coating through the roller brush 33 or repair, level and remove the excess coating through the scraper 34. There is no need to carry two tools, the roller brush and the scraper, at the same time and frequently take and place them for switching use, effectively simplifying the operation process and improving the operation efficiency. In addition, the waterproof coating in the coating tank 21 can be conveyed to the spray head 35 by the water pump 22, and the spray head 35 continuously adds the waterproof coating to the roller brush 33, so that the waterproof coating on the surface of the roller brush 33 is sufficient and the coating operation can be carried out continuously for a long time.

[0052] Specifically, the spray head 35 can be connected to the output end of the water pump 22 through a flexible pipe.

[0053] In one embodiment, a locking jack and an installation hole that are perpendicular and intersecting are formed at the first end of the hand-held rod 31. The rotating frame 32 includes a rotating frame body 321 and a rotating shaft 322 fixedly connected to the rotating frame body 321. The roller brush 33, the scraper 34 and the spray head 35 are all arranged on the rotating frame body 321. The rotating shaft 322 is rotatably inserted into the installation hole and is provided with a locking through hole that is aligned with the locking jack. The locking member 36 is detachably inserted through the locking jack and the locking through hole.

[0054] It can be understood that the rotating frame 32 is rotatably arranged at the first end of the hand-held rod 31 by the rotating shaft 322 being rotatably inserted into the installation hole; and the locking member 36 locks or unlocks the rotating frame 32 and the hand-held rod 31 by being detachably inserted through the locking jack and the locking through hole.

[0055] In one embodiment, referring to the attached Figure 3As shown, the locking member 36 is a ball-head locking pin.

[0056] Specifically, the ball head locking pin is a component well known to those skilled in the art, including a rod-shaped pin shell, a push rod axially movably inserted into the pin shell, a spring sleeved on the push rod, and a ball head that can extend from an opening at one end of the pin shell. The push rod will remain in a locked position under the elastic force of the spring. In the locked position, the push rod continuously presses the ball head so that the retained part of the ball head extends from the opening of the pin shell. By pressing the push rod, the push rod can overcome the elastic force of the spring and move to an unlocked position. In the locked position, the push rod removes the pressure on the ball head so that the ball head can be completely retracted into the pin shell. In this way, the locking member 36 can be detachably inserted through the locking socket and the locking through hole through the extension and retraction of the ball head. The locking and unlocking operations are simple and quick, effectively improving the convenience of the operator in switching the roller brush 33 and the scraper 34.

[0057] In actual application, by pressing the push rod so that the ball head can be completely retracted into the pin housing, the locking piece 36 can be taken out of the locking socket and the locking through hole, thereby unlocking the rotating frame 32 and the hand-held rod 31. The locking piece 36 is inserted into the locking socket and the locking through hole and the pressure on the push rod is removed, so that the ball head can be extended to contact the hole wall of the locking socket, thereby locking the rotating frame 32 and the hand-held rod 31.

[0058] In one embodiment, referring to the attached Figure 3 As shown, the locking socket includes a first hole section and a second hole section connected to each other, and the diameter of the second hole section is larger than that of the first hole section so that the connection between the second hole section and the first hole section forms a step surface that cooperates with the ball stop of the ball head locking pin. Such a configuration can improve the reliability and stability of the locking member 36 passing through the locking socket and the locking through hole, and improve the stability of the locking member 36 locking the rotating frame 32 and the hand-held rod 31.

[0059] In one embodiment, referring to the attached Figure 2 and attached Figure 3 The rotating frame body 321 includes a first connecting rod, a second connecting rod and an intermediate connecting rod, the intermediate connecting rod is fixedly connected to the rotating shaft 322 and is perpendicular to each other, the first connecting rod and the second connecting rod are respectively vertically extended from both ends of the intermediate connecting rod and are arranged oppositely, the roller brush 33 is rotatably sleeved on the first connecting rod, and the scraper 34 and the nozzle 35 are respectively fixedly arranged on the second connecting rod. In this way, the scraper 34 and the roller brush 33 can be arranged at intervals on both sides of the rotating axis of the rotating frame 32.
