[0001] This utility model relates to the field of building waterproofing engineering technology, specifically a waterproof coating spraying tool with a flexible nozzle. Background Technology

[0002] Waterproof coating spraying tools are key equipment to ensure construction quality and efficiency. Among them, the flexible nozzle is the core component, and its performance directly affects the coating's adhesion, ease of construction, and applicable scenarios.

[0003] Currently available flexible nozzle waterproof coating spraying tools have significant limitations in terms of angle adjustment and fixation. Traditional products have a simple connection structure between the spray plate and the fixing plate, relying mainly on external fasteners such as bolts to fix the angle. During construction, operators need to use tools such as wrenches to loosen the fasteners, adjust the angle, and then tighten them again. This is not only cumbersome and time-consuming, but also affects the spraying accuracy and may even cause paint waste and rework. Therefore, we need to provide flexible nozzle waterproof coating spraying tools. Utility Model Content

[0006] The spray plate includes a liquid supply pipe, side plates, a mounting plate, and a nozzle angle adjustment component. The spray plate has two side plates on its back, which are rotatably mounted on both sides of the mounting plate. The nozzle angle adjustment component is mounted on both sides of the mounting plate and is used to limit the rotation of the side plates to achieve the rotation adjustment of the spray plate.

[0007] The nozzle angle adjustment component includes a groove, a column, and a damping part. The groove is symmetrically opened on both sides of the mounting plate, and the column is fixedly installed inside. The side plate is slidably sleeved on the outer peripheral surface of the column. The damping part is installed in the groove to make it difficult for the side plate to rotate, so as to limit the side plate after rotation.

[0008] Preferably, the damping part includes a rubber sleeve and holes. The rubber sleeve has multiple holes distributed in a ring inside. The rubber sleeve is configured as a deformable rubber sleeve. The rubber sleeve is movably sleeved on the surface of the column and located in the groove.

[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. 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a waterproof coating spraying tool with a flexible nozzle, comprising:

[0025] The spray plate 1, liquid supply pipe 2, side plate 3, mounting plate 4 and nozzle angle adjustment component 5 are provided. The back of the spray plate 1 is provided with two side plates 3, which are rotatably mounted on both sides of the mounting plate 4. The nozzle angle adjustment component 5 is mounted on both sides of the mounting plate 4 and is used to limit the rotation of the side plates 3 so as to realize the rotation adjustment of the spray plate 1.

[0026] The nozzle angle adjustment component 5 includes a groove 51, a column 52 and a damping part 53. The groove 51 is symmetrically opened on both sides of the mounting plate 4. The column 52 is fixedly installed inside. The side plate 3 is slidably sleeved on the outer peripheral surface of the column 52. The damping part 53 is installed in the groove 51 to make it difficult for the side plate 3 to rotate, so as to limit the side plate 3 after rotation.

[0027] Specifically, nozzle angle adjustment components 5 are provided on both sides of the mounting plate 4, which can adjust the nozzle angle between the side plate 3 and the spray plate 1, and also act as a limit after the nozzle angle is adjusted. The nozzle angle adjustment components 5 on both sides of the mounting plate 4 make the angle adjustment between the side plate 3 and the spray plate 1 more flexible. Without the need for additional tools, the construction personnel can quickly adjust according to different spraying scenarios. After adjustment, the damping part 53 achieves stable limit, avoiding angle deviation caused by vibration or hand shaking during spraying, ensuring uniform coating coverage, reducing missed spraying and re-spraying, and improving the quality of waterproof construction.

[0028] The damping part 53 includes a rubber sleeve 531 and a hole 532. The rubber sleeve 531 has a plurality of holes 532 distributed in a ring inside. The rubber sleeve 531 is configured as a deformable rubber sleeve. The rubber sleeve 531 is movably sleeved on the surface of the column 52 and located in the groove 51. One side of the rubber sleeve 531 is tightly attached to the surface of the side plate 3.

[0029] Furthermore, the adhesive sleeve 531 of the damping part 53 is made of highly elastic and wear-resistant silicone rubber. Multiple annularly distributed holes 532 inside are circular through holes with a diameter of 1-3 mm, arranged at uniform intervals. The adhesive sleeve 531 is tightly and movably fitted onto the surface of the column 52, located within the groove 51. When the side plate 3 rotates, the annular rough surface 6 on one side of the side plate 3 presses against the adhesive sleeve 531. Due to the high elasticity of the adhesive sleeve 531 material and the compressible deformation characteristics of the holes 532, the adhesive sleeve 531 deforms, with one side tightly adhering to the annular rough surface 6, generating significant friction. This effectively hinders the rotation of the side plate 3, thereby achieving stable positioning after the side plate 3 rotates. This ensures that the spray plate 1 remains fixed after angle adjustment, preventing angle changes due to vibration or external interference during spraying, and ensuring uniform and precise spraying of the coating onto the target surface.

[0030] An annular rough surface 6 is provided on one side of the side plate 3, and the annular rough surface 6 is in contact with one side of the adhesive sleeve 531;

[0031] It is worth noting that the annular rough surface 6 on one side of the side plate 3 is formed by a knurling process during machining, with a knurling depth of 0.3-0.5mm and a groove spacing of 0.5-0.8mm. When this annular rough surface 6 is attached to one side of the adhesive sleeve 531, it increases the contact friction between the two, further enhancing the damping effect. When the side plate 3 rotates on the surface of the column 52, the annular rough surface 6 continuously interacts with the adhesive sleeve 531. Even in complex construction environments, such as high humidity and dusty places, it can ensure the limiting stability of the side plate 3 after rotation, preventing the spray plate 1 from shifting due to a decrease in friction caused by environmental factors, and improving the reliability of the spraying tool under different working conditions.

[0032] A ring-shaped rubber sleeve 7 is fixedly installed on one side of the side plate 3, and one side of the ring-shaped rubber sleeve 7 is in contact with the surface of the mounting plate 4;

[0033] It should be noted that the annular rubber sleeve 7 fixedly installed on one side of the side plate 3 is made of nitrile rubber, which has good sealing performance and oil resistance. One side of the annular rubber sleeve 7 is tightly fitted to the surface of the mounting plate 4. During the rotation of the side plate 3, the annular rubber sleeve 7 plays an auxiliary sealing and buffering role. On the one hand, it prevents external dust, moisture and other impurities from entering the interior of the tank 51, avoiding corrosion of the damping part 53 and the rotating structure or affecting its normal operation; on the other hand, when the side plate 3 rotates, the annular rubber sleeve 7 can buffer the frictional impact between the side plate 3 and the mounting plate 4, reduce component wear, extend the overall service life of the equipment, and enhance the adaptability of the equipment in harsh construction environments.

[0034] It also includes a mounting component 8 for removing the spray plate 1. The mounting component 8 includes a rectangular groove 81, a slide 82, a rod 83 and a spring 84. The slide 82 is fixedly installed at one end of the side plate 3. The rod 83 is fixedly installed in the rectangular groove 81 on one side of the spray plate 1. The slide 82 is slidably installed on the surface of the rod 83. A spring 84 is provided between one side of the slide 82 and the inner wall of the rectangular groove 81. The spring 84 is movably sleeved on the surface of the rod 83.

[0035] Specifically, the slide block 82 is made of high-strength aluminum alloy and precision machined, resulting in a smooth surface and high dimensional accuracy, ensuring smooth sliding on the surface of the rod 83. A clearance fit is used between the slide block 82 and the rod 83, with the clearance controlled between 0.05-0.1mm. The spring 84 is made of high-carbon steel and undergoes heat treatment, possessing high elastic limit and fatigue strength, with an elastic coefficient of 10-15N / mm. When the side plate 3 rotates, the spring 84 within the mounting component 8 uses its own elastic force to push the side plate 3 against the rubber sleeve 531, further increasing the friction between the side plate 3 and the rubber sleeve 531, facilitating more precise adjustment of the spray plate 1 angle. When it is necessary to remove the spray plate 1, pulling the two side plates 3 away from each other causes the slide block 82 to slide along the rod 83 within the rectangular groove 81, compressing the spring 84 and allowing the side plate 3 to easily detach from the surface of the column 52, achieving convenient removal of the spray plate 1 and improving the efficiency of equipment maintenance and component replacement.

[0036] A protective plate 9 for protecting the spring 84 is fixedly installed inside the rectangular groove 81. The surface of the protective plate 9 is slidably installed inside the slide block 82.

[0037] The protective plate 9, fixedly installed within the rectangular groove 81, is made of stainless steel with a thickness of 1-2 mm. The surface of the protective plate 9 is polished, and the sliding fit precision between it and the inner surface of the slide block 82 is controlled within 0.03-0.08 mm. The main function of the protective plate 9 is to protect the spring 84, preventing contamination, corrosion, or damage to the spring 84 during construction due to paint splatter, falling debris, etc., ensuring that the spring 84 is always in good working condition.

[0038] A connecting plate 10 is rotatably mounted inside the mounting plate 4. A limit bolt 11 is threaded inside the connecting plate 10. An extrusion plate 12 is rotatably mounted at the bottom of the limit bolt 11.

[0039] Furthermore, the connecting disc 10 is rotatably mounted inside the mounting plate 4. The limiting bolt 11 inside the connecting disc 10 adopts a modified triangular thread with self-locking function. The thread helix angle is designed to be 1.5°-2.5°. After phosphating treatment, the thread surface is coated with an 8-12μm Dacromet coating and impregnated with silicone sealant to form a sealing layer, which has excellent corrosion resistance. When it is necessary to adjust the overall horizontal rotation angle of the mounting plate 4, rotating the connecting disc 10 will drive the mounting plate 4 to rotate. After adjustment, rotating the limiting bolt 11 will cause the pressing plate 12 at the bottom of the limiting bolt 11 to be tightly pressed against the top of the mounting plate 4. The self-locking performance of the thread and the clamping force of the pressing plate 12 are used to reliably fix the mounting plate 4, ensuring that the mounting plate 4 will not be displaced during the spraying process and ensuring the accuracy of the spraying direction.

[0040] The top of the mounting plate 4 is hinged with a cover 13 for protecting the limit bolt 11;

[0041] The cover 13, hinged to the top of the mounting plate 4, is made of engineering plastic, which has the advantages of being lightweight, corrosion-resistant, and having good insulation. The cover 13 is hinged to the top of the mounting plate 4 via stainless steel hinges, which allow for flexible rotation and smooth opening and closing. The main function of the cover 13 is to protect the limit bolt 11, preventing it from being damaged by impacts, scratches, or paint contamination during construction. This avoids damage to the threads and a decrease in self-locking performance of the limit bolt 11 due to external forces or environmental factors, ensuring that the limit bolt 11 always functions normally.

[0042] All threaded mounting surfaces in this application utilize a modified triangular thread with a self-locking function. The thread helix angle is designed to be 1.5°-2.5° to enhance the anti-loosening effect. After phosphating, the thread surface is coated with an 8-12μm Dacromet coating and impregnated with silicone sealant to form a sealing layer, resulting in excellent corrosion resistance. In addition, the thread can effectively expel dust, and it can still be used normally even if a small amount of dust adheres to it.

[0043] The liquid supply pipe 2 adopts a double-layer structure design. The inner layer is made of polytetrafluoroethylene (PTFE) material that is resistant to high pressure and chemical corrosion, while the outer layer is wrapped with a reinforcing layer made of highly elastic steel wire with a diameter of 0.2-0.5mm and a braiding density of not less than 80%. The joint between the liquid supply pipe 2 and the surface of the spray plate 1 adopts a detachable quick-sealing connection structure. An oil-resistant rubber sealing ring is provided at the joint to ensure the sealing of the connection and prevent paint leakage.

[0044] When the nozzle needs to be bent, rotating the spray plate 1 causes the two side plates 3 to rotate. The side plates 3 rotate on the surface of the column 52. Because one side of the side plate 3 has an annular rough surface 6, it is pressed against the adhesive sleeve 531 in the groove on the side of the mounting plate 4. The adhesive sleeve 531 has multiple holes 532, which causes the adhesive sleeve 531 to deform. One side of the adhesive sleeve 531 is tightly fitted with the annular groove surface, resulting in high friction, making it difficult for the side plate 3 to rotate. After rotation, a damping force is generated, which limits the spray plate 1. The side plate 3 is installed in the spray plate 1 through the mounting part 8. The spring 84 in the mounting part 8 will drive the side plate 3 to press the adhesive sleeve 531, further increasing the friction and facilitating the spray plate 1. The angle is adjusted, and the two side plates 3 are pulled away from each other. The side plates 3 drive the slide 82 to slide in the rectangular groove 81, squeezing the spring 84, which can make the side plates 3 detach from the surface of the column 52, thereby removing the spray plate 1. The surface joint of the spray plate 1 and the liquid supply pipe 2 are detachably sealed, which can facilitate the replacement of the spray plate 1. A protective cover 13 is provided on one side of the spring 84 to protect the spring 84. The mounting plate 4 is rotatably mounted on the connecting plate 10, which can realize the overall horizontal rotation of the mounting plate 4. By rotating the limiting bolt 11, the bottom pressing plate 12 of the limiting bolt 11 is pressed against the top of the mounting plate 4 to fix the mounting plate 4. A protective cover 13 is provided to protect the limiting bolt 11.
