Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, specifically a spray painting equipment for building construction. Background Technology

[0002] In building construction, spray painting equipment can efficiently and evenly apply paint to building surfaces such as walls, beams, and columns. Its function is to quickly cover large areas, resulting in a smoother, more uniform paint finish, thus improving construction efficiency and coating quality. Furthermore, different types of spray painting equipment can adjust the spray pressure, flow rate, and atomization level according to specific construction needs, adapting to different paints and construction environments.

[0003] Existing spray painting equipment still has some shortcomings in practical applications. First, the existing spray painting equipment on the market lacks a cover and seal for the spray nozzle, which makes it easy for dust to enter the spray nozzle when the spray painting equipment is not in use, and over time it will affect the spray painting effect of the spray nozzle. Utility Model Content

[0004] The purpose of this invention is to provide a painting device for building construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray painting device for building construction, comprising a spray pipe, a handle fixedly installed on the outer wall of the spray pipe, a nozzle fixedly installed at the end of the spray pipe, a trigger hinged to the outer wall of the spray pipe, a sealing mechanism provided in the nozzle, and a shielding mechanism provided in the nozzle. The sealing mechanism includes: a rotating rod rotatably connected to the outer wall of the spray pipe, and an L-rod fixedly installed on the outer wall of the rotating rod.

[0006] Preferably, a torsion spring is sleeved on the outer wall of the rotating rod, and a fixing rod is fixedly installed at the end of the rotating rod.

[0007] Preferably, a slidable rod is slidably connected to the inner wall of the nozzle, a hinge rod is hinged to the upper surface of the L-rod, and a sealing plate is slidably installed on the inner wall of the nozzle.

[0009] Preferably, one end of the torsion spring is fixedly installed on the outer wall of the nozzle, and the other end of the torsion spring is fixedly installed on the outer wall of the L-rod. One end of the hinge rod is hinged to the outer wall of the L-rod, and the other end of the hinge rod is hinged to the outer wall of the trigger. The upper surface of the sealing plate slides on the inner wall of the L-rod, and the end of the unblocking rod is hinged to the outer wall of the fixing rod. By setting the torsion spring, the L-rod can perform a quick reset function.

[0010] Preferably, one end of the rectangular rod is hinged to the bottom of the connecting plate, and the other end of the rectangular rod is hinged to the end of the L-shaped rod. By setting the rectangular rod, the connecting plate can be displaced.

[0011] Compared with the prior art, this utility model provides a painting device for building construction, which has the following beneficial effects:

[0012] 1. In order to prevent dust from entering the spray nozzle, this construction spraying device is equipped with a rotating rod, an L-shaped rod, a torsion spring, a fixing rod, a clearing rod, a hinge rod, and a sealing plate to clear and seal the spray nozzle, preventing dust from entering the interior and affecting subsequent spraying work.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a painting device for building construction, including a spray pipe 1, a handle 2 fixedly installed on the outer wall of the spray pipe 1, a nozzle 3 fixedly installed at the end of the spray pipe 1, a trigger 4 hinged to the outer wall of the spray pipe 1, a sealing mechanism 5 provided in the nozzle 3, and a shielding mechanism 6 provided in the nozzle 3.

[0020] The sealing mechanism 5 includes: a rotating rod 501, an L-shaped rod 502, a torsion spring 503, a fixing rod 504, a clearing rod 505, a hinged rod 506, and a sealing plate 507. The rotating rod 501 is rotatably connected to the outer wall of the nozzle 1. The L-shaped rod 502 is fixedly installed on the outer wall of the rotating rod 501. The torsion spring 503 is sleeved on the outer wall of the rotating rod 501. One end of the torsion spring 503 is fixedly installed on the outer wall of the nozzle 1, and the other end of the torsion spring 503 is fixedly installed on the L-shaped rod 502. The outer wall of the nozzle 3 has a fixed rod 504 fixedly installed at the end of the rotating rod 501. A slidable unblocking rod 505 is slidably connected to the inner wall of the nozzle 1. The end of the unblocking rod 505 is hinged to the outer wall of the fixed rod 504. A hinge rod 506 is hinged to the upper surface of the L rod 502. One end of the hinge rod 506 is hinged to the outer wall of the L rod 502, and the other end of the hinge rod 506 is hinged to the outer wall of the trigger 4. A sealing plate 507 is slidably installed on the inner wall of the nozzle 3. The upper surface of the sealing plate 507... The surface slides on the inner wall of L-rod 502. By pulling trigger 4, trigger 4 rotates backward, causing hinge rod 506 to pull L-rod 502, which also rotates backward. At this time, as L-rod 502 rotates, it pulls sealing plate 507 to slide upward on the inner wall of nozzle 3 and protrude from nozzle 3. While L-rod 502 rotates, fixing rod 504 pushes unblocking rod 505 to slide forward on the inner wall of nozzle 1 and push out the paint residue left on the inner wall of nozzle 1 from the previous work. After the painting work is completed, release trigger 4. At this time, L-rod 502 loses tension, and torsion spring 503 will cause L-rod 502 to rotate forward and complete the reset. During the process of L-rod 502 rotating forward and resetting, L-rod 502 will cause sealing plate 507 to slide downward on the inner wall of nozzle 3 to complete the seal and prevent dust from entering. At this time, fixing rod 504 will pull unblocking rod 505 to slide backward on the inner wall of nozzle 1 as L-rod 502 resets.

[0021] The aforementioned shielding mechanism 6 includes: a fixing block 601, a receiving plate 602, and a rectangular rod 603. The fixing block 601 is fixedly installed on the outer wall of the nozzle 3. The receiving plate 602 is slidably connected to the inner wall of the fixing block 601. The rectangular rod 603 is hinged to the bottom of the receiving plate 602. One end of the rectangular rod 603 is hinged to the bottom of the receiving plate 602, and the other end of the rectangular rod 603 is hinged to the end of the L rod 502. As the L rod 502 rotates, the rectangular rod 603 at the end of the L rod 502 will push the receiving plate 602 to slide forward on the inner wall of the fixing block 601. The receiving plate 602 will catch the paint dripping from the nozzle 3. At the same time as the L rod 502 resets, the rectangular rod 603 will pull the receiving plate 602 to move backward to complete the recycling.

[0022] Working principle: Pulling trigger 4 causes it to rotate backward, which in turn pulls hinge rod 506 to rotate L rod 502 backward. As L rod 502 rotates, it pulls sealing plate 507 upward along the inner wall of nozzle 3, allowing nozzle 3 to protrude. Simultaneously, fixing rod 504 pushes unblocking rod 505 forward along the inner wall of nozzle 1, pushing out paint residue left from the previous operation. Then, as L rod 502 rotates, rectangular rod 603 at the end of L rod 502 pushes connecting plate 602 forward along the inner wall of fixing block 601. Plate 602 catches the paint dripping from nozzle 3. After the painting work is completed, release trigger 4. At this time, L rod 502 loses tension. Torsion spring 503 will cause L rod 502 to rotate forward and complete the reset. During the process of L rod 502 rotating forward and resetting, L rod 502 will cause sealing plate 507 to slide down on the inner wall of nozzle 3 to complete the seal and prevent dust from entering. At this time, fixing rod 504 will pull unblocking rod 505 to slide backward on the inner wall of spray pipe 1 as L rod 502 resets. At this time, rectangular rod 603 at the end of L rod 502 will pull receiving plate 602 to move backward to complete the retraction.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
