Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically to an adjustable-angle descaling and cleaning nozzle. Background Technology

[0002] A descaling and cleaning nozzle is a specialized device component used to remove various types of dirt and grime. It is typically installed on cleaning tools or equipment, such as pressure washers and hose spray guns. Its core function is to spray cleaning liquid (such as water or detergent solution) at a specific pressure and angle, using the impact force of the liquid to peel and flush away dirt, thus achieving the purpose of cleaning. Different types of descaling and cleaning nozzles have their own characteristics in terms of structure and function.

[0003] Traditional spray nozzles are typically designed with a fixed angle, making it difficult to fully cover contaminated areas in complex cleaning scenarios. For example, in cleaning industrial equipment, the surface structure is complex, with many corners and grooves. Fixed-angle spray nozzles cannot effectively reach these areas, resulting in dirt residue that affects the normal operation and lifespan of the equipment. Furthermore, the nozzles cannot be stably clamped during use, causing them to wobble and shift due to the impact of water pressure, resulting in low stability during the cleaning process. Utility Model Content

[0004] To address the issues of inability to adjust the angle and difficulty in stabilizing the nozzle, the purpose of this invention is to provide an adjustable-angle descaling and cleaning nozzle.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an adjustable angle descaling and cleaning nozzle, comprising a U-shaped plate, a support plate symmetrically fixedly installed on one side of the U-shaped plate, a rotating platform rotatably connected between the two support plates, a clamping device fixedly installed on one side of the rotating platform, a nozzle body fixedly installed inside the clamping device, and fan-shaped adjusting plates fixedly sleeved on both outer surfaces of the rotating platform, a connector fixedly connected to the outer surface of the fan-shaped adjusting plate, a telescopic component fixedly connected to one side of the connector, and a side of the telescopic component rotatably connected to the support plate.

[0006] Preferably, the clamping device includes a base plate, one side of which is fixedly connected to a rotating platform, and the other side of which is rotatably connected to a bidirectional threaded rod. A handwheel is fixedly sleeved at one end of the bidirectional threaded rod, and a movable plate is symmetrically threaded onto the outer surface of the bidirectional threaded rod. A connecting plate is fixedly connected to one side of the movable plate, and one side of the connecting plate is slidably connected to the outer surface of the base plate. A clamping plate is fixedly connected to one side of the connecting plate, and the nozzle body is located between the two clamping plates.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This utility model utilizes a telescopic assembly to rotate a fan-shaped adjusting plate, thereby rotating the rotating platform and allowing for flexible adjustment of the nozzle body's angle. The sliding connection between the arc-shaped guide groove and the stabilizing plate ensures rotational stability; the cooperation between the equidistant adjusting groove and the fixing bolts allows for precise positioning and fixing of the rotation angle, enabling users to quickly adjust the nozzle to the appropriate angle according to different descaling and cleaning scenarios and locations. In the clamping device, rotating the handwheel drives the bidirectional threaded rod, causing the two moving plates to move towards or away from each other, which in turn moves the connecting plate and the clamping plate. This design allows for adjustment according to different nozzle body dimensions, ensuring the nozzle is securely clamped. Attached Figure Description

[0015] 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.

[0016] Example: Figure 1-4 As shown, this utility model provides an adjustable-angle descaling and cleaning nozzle, including a U-shaped plate 11. Multiple mounting slots are symmetrically arranged on the outer surface of the U-shaped plate 11. In different cleaning equipment or working scenarios, a suitable mounting slot can be selected to install the nozzle in the corresponding position according to actual needs. Support plates 12 are symmetrically fixedly installed on one side of the U-shaped plate 11. A rotating platform 13 is rotatably connected between the two support plates 12. A clamping device 10 is fixedly installed on one side of the rotating platform 13. A nozzle body 14 is fixedly installed inside the clamping device 10. Both outer surfaces of the rotating platform 13 are fixedly sleeved with... The fan-shaped adjusting plate 15 has an arc-shaped guide groove 16 on its outer surface. A stabilizing plate 18 is slidably connected to the outer surface of the arc-shaped guide groove 16. The stabilizing plate 18 passes through the arc-shaped guide groove 16 and is fixedly connected to the support plate 12. This structure provides a stable guide for the rotation of the fan-shaped adjusting plate 15 during the nozzle angle adjustment process. When the rotating table 13 drives the fan-shaped adjusting plate 15 to rotate to change the nozzle angle, the stabilizing plate 18 slides in the arc-shaped guide groove 16 to prevent the fan-shaped adjusting plate 15 from shaking or deviating when rotating, thus ensuring the stability and accuracy of the nozzle angle adjustment.

[0017] A connector 20 is fixedly connected to the outer surface of the fan-shaped adjusting plate 15. Multiple equidistant adjusting slots 17 are formed on the outer surface of the fan-shaped adjusting plate 15. Two fixing bolts 21, which are used in conjunction with the equidistant adjusting slots 17, are fixedly inserted into the outer surface of the connector 20. After the nozzle is adjusted to a suitable angle, the fixing bolts 21 can be inserted into the corresponding equidistant adjusting slots 17 to fix the nozzle angle. This design prevents the nozzle from shifting angle due to water flow impact or other external forces during operation, ensuring the stability of the nozzle angle during cleaning. It is suitable for long-term, high-intensity cleaning operations. A telescopic component 19 is fixedly connected to one side of the connector 20. One side of the telescopic component 19 is rotatably connected to the support plate 12. The support plate 12 on the U-shaped plate 11 supports the rotation of the rotating platform 13, causing the nozzle body 14 fixed on the rotating platform 13 to change its orientation. The fan-shaped adjusting plate 15 is sleeved on both sides of the rotating platform 13 and connected to the telescopic component 19 via the connector 20. When the telescopic component 19 extends or retracts, pulling the connector 20 causes the fan-shaped adjustment plate 15 to rotate around the axis of the rotating platform 13, thereby rotating the rotating platform 13 and adjusting the nozzle angle. During this process, the arc-shaped guide groove 16 of the fan-shaped adjustment plate 15 slides in conjunction with the stabilizing plate 18 on the support plate 12 to ensure smooth and precise adjustment.

[0018] The clamping device 10 includes a base plate 26. One side of the base plate 26 is fixedly connected to the rotating table 13, and the other side of the base plate 26 is rotatably connected to a bidirectional threaded rod 27. One end of the bidirectional threaded rod 27 is fixedly sleeved with a handwheel 33. A movable plate 28 is symmetrically threaded onto the outer surface of the bidirectional threaded rod 27. A connecting plate 31 is fixedly connected to one side of the movable plate 28. One side of the connecting plate 31 is slidably connected to the outer surface of the base plate 26. A slide rail 29 is fixedly connected to the outer surface of the base plate 26. A slider 30 is symmetrically slidably sleeved onto the outer surface of the slide rail 29. The upper surface of the slider 30 is fixedly connected to the connecting plate 31. When the handwheel 33 is turned, the bidirectional threaded rod 27 is rotated, causing the movable plate 28 to move to adjust the spacing of the clamping plates 32 to adapt to nozzle bodies 14 of different sizes. The slider 30 slides on the slide rail 29 to ensure that the movable plate 28 moves smoothly, avoiding jamming or displacement, and ensuring the stability of nozzle clamping.

[0019] A clamping plate 32 is fixedly connected to the other side of the connecting plate 31. One side of the clamping plate 32 is V-shaped. Regardless of whether the nozzle is round, elliptical, or has other irregular shapes, the V-shaped clamping plate 32 can increase the contact area with the nozzle, providing a more stable clamping force and preventing the nozzle from shaking or falling off during cleaning. The nozzle body 14 is located between the two clamping plates 32. Rotating the handwheel 33 drives the bidirectional threaded rod 27 to rotate, causing the symmetrically threaded moving plates 28 to move axially towards or away from each other. The slide rail 29 on the base plate 26 cooperates with the slider 30 to ensure the smooth movement of the moving plates 28 and avoid deviation and jamming. The moving plates 28 drive the clamping plates 32 to move through the connecting plate 31, thereby clamping and fixing the nozzle body 14. The spacing can be adjusted by rotating the handwheel 33 according to the nozzle size.

[0020] The telescopic assembly 19 includes a housing 22. A telescopic pin 24 is slidably connected to the inner surface of the housing 22. A threaded rod 23 is rotatably connected inside the housing 22. A transmission sleeve 25 is threadedly fitted onto the outer surface of the threaded rod 23. The outer surface of the transmission sleeve 25 is fixedly connected to the telescopic pin 24. One end of the telescopic pin 24 is rotatably connected to the connector 20. When the threaded rod 23 inside the housing 22 rotates, it drives the threaded transmission sleeve 25 and the connected telescopic pin 24 to slide, thereby realizing the extension and retraction of the assembly. This design allows the length of the telescopic assembly 19 to be flexibly controlled according to actual needs when adjusting the nozzle angle, thereby precisely adjusting the nozzle angle to adapt to complex cleaning scenarios, such as cleaning dirt in different locations inside industrial pipelines. By adjusting the telescopic assembly 19, the nozzle can be aimed at the dirt at a suitable angle.

[0021] Working principle: The U-shaped plate 11 serves as the basic support component of the entire device. Symmetrically fixed support plates 12 on one side provide rotational support points for the rotating platform 13. A rotatable connection is formed between the rotating platform 13 and the two support plates 12, allowing the rotating platform 13 to rotate within a certain angle range. The fan-shaped adjusting plate 15 is fixedly sleeved on both outer surfaces of the rotating platform 13 and connected to the telescopic assembly 19 via connectors 20. One end of the telescopic assembly 19 is connected to the fan-shaped adjusting plate 15, and the other end is rotatably connected to the support plate 12. When the threaded rod 23 is rotated, the transmission sleeve 25 moves axially along the threaded rod 23 due to the threaded transmission, thereby causing the telescopic pin 24 to slide on the inner surface of the outer casing 22, realizing the telescopic function of the telescopic assembly 19 to meet the needs of adjusting the nozzle angle. When the telescopic assembly 19 extends or retracts, it drives the fan-shaped adjustment plate 15 to rotate, thereby causing the rotating platform 13 to rotate, realizing the adjustment of the overall angle of the nozzle body 14. The arc-shaped guide groove 16 on the outer surface of the fan-shaped adjustment plate 15 is slidably connected to the stabilizing plate 18 fixed on the support plate 12, playing a guiding and stabilizing role in rotation, ensuring the stability of the rotating platform 13 when rotating. At the same time, the equidistant adjustment groove 17 on the outer surface of the fan-shaped adjustment plate 15 works in conjunction with the fixing bolt 21 fixedly inserted on the outer surface of the connector 20 to position and fix the rotation angle of the rotating platform 13, preventing it from shaking during operation.

[0022] The base plate 26 is fixedly connected to the rotating platform 13, serving to connect the rotating platform 13 and the clamping part. The bidirectional threaded rod 27 is rotatably connected to the other side of the base plate 26, and the handwheel 33 is fixedly sleeved on one end of the bidirectional threaded rod 27. Rotating the handwheel 33 can drive the bidirectional threaded rod 27 to rotate. The moving plates 28 are symmetrically threaded onto the outer surface of the bidirectional threaded rod 27. When the bidirectional threaded rod 27 rotates, the two moving plates 28 will move towards or away from each other along the bidirectional threaded rod 27. As the moving plates 28 move, the clamping plate 32 will move accordingly, thereby achieving clamping and fixing of the nozzle body 14, and can be adjusted according to the size of the nozzle body 14.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
