Technical Field
[0001] This utility model relates to the field of spray gun head technology, and in particular to a multi-functional adjustment device for an exterior wall paint spray gun head. Background Technology
[0002] An exterior paint spray gun is a tool specifically designed for spraying exterior wall coatings. It is available in pneumatic, electric, and hand-operated versions. Compared to traditional brushes or rollers, spray guns can significantly increase painting speed, especially for large-area applications. Furthermore, spray guns produce fine mist particles, resulting in a more uniform coating and avoiding brush and roller marks.
[0003] In the process of exterior facade decoration, in pursuit of spraying efficiency, traditional spray guns have a large scattering range. This requires workers to frequently change the angle of the gun to adjust the width of the sprayed lines. This method is particularly inconvenient when dealing with buildings such as kindergartens, which have diverse exterior wall colors and numerous fine lines. First, it is necessary to increase the protection of surrounding objects, and to provide comprehensive protection for all surrounding exterior surfaces such as window frames, glass, aluminum cladding, and stone cladding to prevent paint splattering and pollution. However, comprehensive protection of finished products not only increases the workload, including steps such as applying film, covering, and removing it, but also extends the construction period. In addition, in order to ensure the clarity of the separation between different colors, this type of spray gun may require multiple layers of spraying, which leads to serious paint waste and increases material costs. These factors combined not only reduce construction efficiency and increase project costs, but may also lead to problems such as uneven coating thickness and blurred boundaries, affecting the final decorative effect and quality.
[0004] Therefore, it is necessary to design a multi-functional adjustment device for exterior wall paint spray gun heads to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-functional adjustment device for exterior wall paint spray gun heads.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A multi-functional adjustment device for an exterior wall paint spray gun head includes a connecting cylinder and an adjustment nozzle. The top of the connecting cylinder is provided with an installation groove, which is connected to the inside of the connecting cylinder. The bottom of the adjustment nozzle is fixed with an installation cylinder, which is adapted to the installation groove. The side wall of the adjustment nozzle is provided with a locking groove. All four side walls of the connecting cylinder are provided with fixing components.
[0008] As a preferred technical solution of this utility model, the fixing component includes two fixing plates fixedly connected to the side wall of the connecting cylinder, and a rotating shaft is rotatably connected between the two fixing plates. A torsion spring is provided between the rotating shaft and the fixing plates. A rotating plate is fixedly sleeved on the rotating shaft. A locking block is fixed on the rotating plate at the top of the side wall of the connecting cylinder, and the locking block corresponds to the locking groove.
[0009] As a preferred technical solution of this utility model, the connecting cylinder is provided with a sealing component inside. The sealing component includes a slot opened inside the mounting groove. A sealing ring is fixed inside the slot, and the sealing ring is hollow inside. Airbags are fixed on the four side walls of the connecting cylinder, and the airbags correspond to the rotating plate. A connecting pipe is connected to the airbag, and the connecting pipe is connected to the sealing ring.
[0010] As a preferred technical solution of this utility model, the side wall of the mounting cylinder is provided with several fastening grooves.
[0011] As a preferred embodiment of this utility model, the longitudinal section of the card block is triangular, and an anti-slip pad is fixed to the bottom of the card block.
[0012] As a preferred embodiment of this utility model, a pressing plate is fixed at the bottom of the side wall of the rotating plate. The longitudinal section of the pressing plate is L-shaped, and the side wall of the pressing plate is provided with anti-slip texture.
[0013] This utility model has the following beneficial effects:
[0014] 1. Improved spraying precision and efficiency: The adjustable nozzle has multiple adjustment functions, which can produce different spraying effects and spraying ranges. This allows workers to more accurately control the width of the sprayed lines, reducing the need to frequently change the nozzle angle and improving the flexibility and efficiency of spraying. The design between the connecting tube and the adjustable nozzle allows the spray gun to quickly change nozzles of different diameters, which is suitable for various spraying needs and improves the flexibility and practicality of the device. For building exterior walls with diverse colors and fine and numerous lines, this device can flexibly cope with and meet complex decoration requirements. Moreover, this simple disassembly and assembly design facilitates daily maintenance and cleaning and extends the service life of the equipment.
[0015] 2. Reduced workload for finished product protection: Since the spray nozzle can precisely control the spraying range, the risk of paint splashing is reduced. Therefore, the need for finished product protection of exterior surfaces such as window frames, glass, aluminum exterior walls, and stone cladding is greatly reduced. This reduces steps such as applying film, covering and removing film, shortens the construction cycle and reduces labor costs.
[0016] 3. Material saving: The multi-level adjustment function and quick nozzle replacement setting ensure that the ideal coating effect can be achieved with one spray, reducing material waste caused by multiple sprays, avoiding uneven coating and blurred boundary problems, further reducing the need for repair and rework, and improving the final decorative effect.
[0017] 4. Improve structural stability: After the sealing ring is inflated, it can fill the fastening groove, which enhances the sealing between the mounting cylinder and the mounting groove, improves the overall structural stability, and prevents the leakage and waste of wall paint.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-4A multi-functional adjustment device for an exterior wall paint spray gun head includes a connecting cylinder 1 and an adjustment nozzle 2. The adjustment nozzle 2 has a multi-level adjustment function. Its internal structure includes one or more sets of valve systems. These valves control the liquid to pass through different orifices or paths, thereby producing different spraying effects and spraying ranges. When the user operates the external controller, it will trigger the action of the internal valves, thereby changing the state of the liquid. This device is similar to the shower equipment in the prior art. Its specific structure and working principle will not be described in detail here. The top of the connecting cylinder 1 is provided with an installation groove 3, and the installation groove 3 is connected to the inside of the connecting cylinder 1. The bottom of the adjustment nozzle 2 is fixed with an installation cylinder 4, which is adapted to the installation groove 3. The inner diameters of the adjustment nozzle 2, the connecting cylinder 1, and the installation cylinder 4 are the same to ensure the smooth flow of liquid. The side wall of the adjustment nozzle 2 is provided with a retaining groove 5.
[0025] Reference Figure 1 and Figure 2 The four side walls of the connecting cylinder 1 are equipped with fixing components. The fixing components include two fixing plates 8 fixedly connected to the side walls of the connecting cylinder 1. A rotating shaft 9 is rotatably connected between the two fixing plates 8. A torsion spring 10 is provided between the rotating shaft 9 and the fixing plates 8. One end of the torsion spring 10 is fixed to the rotating shaft 9, and the other end is fixed to the fixing plate 8. A rotating plate 7 is fixedly sleeved on the rotating shaft 9. A locking block 6 is fixed at the top of the side wall of the rotating plate 7 facing the connecting cylinder 1. The locking block 6 corresponds to the locking groove 5. The longitudinal section of the locking block 6 is triangular. Under the action of this structure, when installing the adjusting nozzle 2, the adjusting nozzle 2 can be directly inserted between several locking blocks 6. The bottom of the locking block 6 is fixed with an anti-slip pad to increase the friction between the locking block 6 and the bottom surface of the locking groove 5 and ensure the stability of the structure. A pressing plate 16 is fixed at the bottom of the side wall of the rotating plate 7. The longitudinal section of the pressing plate 16 is L-shaped, and the side wall of the pressing plate 16 is provided with anti-slip texture to facilitate the operator to control the rotating plate 7.
[0026] Reference Figure 2 , Figure 3 and Figure 4 The connecting cylinder 1 has a sealing assembly inside, which includes a slot 11 inside the mounting groove 3. A sealing ring 12 is fixed inside the slot 11, and the inside of the sealing ring 12 is hollow. Airbags 13 are fixed on the four side walls of the connecting cylinder 1, and the airbags 13 correspond to the rotating plate 7. A connecting pipe 14 is connected to the airbag 13 and is connected to the sealing ring 12. Several fastening grooves 15 are opened on the side wall of the mounting cylinder 4. When the sealing ring 12 is inflated, the sealing ring 12 will deform and fill the fastening grooves 15. This improves the sealing performance between the mounting cylinder 4 and the mounting groove 3, and also improves the stability of the connection between the two.
[0027] The specific working principle of this utility model is as follows:
[0028] When the adjusting nozzle 2 needs to be replaced, the operator holds all the pressing plates 16, causing the rotating plate 7 and the rotating shaft 9 to rotate, which in turn causes the locking block 6 to rotate and disengage from the locking groove 5. This allows the adjusting nozzle 2 to be lifted and disassembled. Conversely, the adjusting nozzle 2 is inserted between several locking blocks 6. Under the action of the inclined surface of the locking block 6, the locking block 6 is squeezed and rotates away from the connecting cylinder 1, which drives the rotating plate 7 and the rotating shaft 9 to rotate together. As the adjusting nozzle 2 moves down, the mounting cylinder 4 can be inserted into the mounting groove 3. When the locking groove 5 corresponds to the locking block 6, under the elastic force of the torsion spring 10, the locking block 6 reverses and resets. At this time, the locking block 6 can be inserted into the locking groove 5 to fix the adjusting nozzle 2. This disassembly and assembly operation is simple and quick, which improves the replacement efficiency of the adjusting nozzle 2, makes the spray gun suitable for nozzles of different diameters, and improves the flexibility and practicality of the device.
[0029] Furthermore, when installing the adjusting nozzle 2, the rotating plate 7 and the locking block 6 will reset under the action of the torsion spring 10. At this time, the rotating plate 7 will squeeze the air bag 13, so that the air in the air bag 13 enters the sealing ring 12 through the connecting pipe 14. The sealing ring 12 inflates and fills the gap between the mounting cylinder 4 and the mounting groove 3, thereby ensuring the sealing between the two and further strengthening the fixation of the adjusting nozzle 2, ensuring the stability of the device structure.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
