Technical Field

[0001] This utility model relates to the field of modular nozzle technology, and in particular to a modular nozzle that is easy to disassemble and replace. Background Technology

[0002] Nozzles are a crucial component in many spraying, misting, oiling, sandblasting, and coating equipment, playing an important role.

[0003] In many industrial applications, such as 3D printing, spraying, and injection molding, nozzles are key components whose performance directly affects product quality and production efficiency. Since different processes have different requirements for nozzle orifice diameter, frequent nozzle replacement has become the norm. Traditional nozzle structures are complicated to operate during disassembly and replacement, which is time-consuming and labor-intensive. Moreover, most of them are threaded screw-on installation structures, which cannot achieve quick installation of nozzles, seriously affecting the continuity of production and resulting in low nozzle utilization efficiency.

[0004] Therefore, we provide a modular nozzle that is easy to replace. Utility Model Content

[0022] 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.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1: A modular nozzle that is easy to replace, such as Figures 1-4As shown, the device includes a main body 1 and sealing tubes 2 disposed on both sides of the main body 1. A threaded rod 4 is installed inside the sealing tube 2. An octagonal piece 3 is installed at one end of the threaded rod 4. A bearing 18 is installed at the end of the threaded rod 4 away from the octagonal piece 3. A rubber clip 17 is installed on one side of the bearing 18. A sleeve 6 is installed at one end of the main body 1. Two insertion slots 7 are installed on the surface of the sleeve 6. A triangular piece 14 is installed on one side of the sleeve 6. The modular nozzle mentioned in this embodiment is suitable for nozzle diameters between DN15 and DN40 and is commonly used in the 3D printing field. During nozzle installation, one end of the pipe connection of the main body 1 is inserted into the interior of the main body 1. The interior of the main body 1 is equipped with a corresponding diameter snap-fit ​​groove (not mentioned in the figure) to provide a liquid-sealed connection for the pipe connection. Each connection point of the main body 1 is equipped with a specific type of sealing ring to prevent liquid leakage during transport. After the main body 1 is installed, rotating the octagonal piece 3 causes the threaded rod 4 to extend into the interior of the main body 1 along the threaded path inside the sealing tube 2. The bearing 18 located inside the main body 1 can then be driven by the threaded rod 4 to... The rotation causes the rubber clip 17, which is fixedly installed at one end of the bearing 18, to advance horizontally and linearly along the threaded rod 4 to fit and clamp the pipe to be installed, making the nozzle installation method more convenient. When adjusting the water flow rate, the corresponding guide piece is pulled out according to the required flow rate. If a larger water flow is required, the second plug rod 9 is taken out from the inside of the plug groove 7, so that the large-diameter spherical guide piece 16 installed at one end can release the sealing restriction on the large-diameter flow hole opened on the triangular piece 14, so that the water flow delivered from the main body 1 can only pass through the large-diameter flow hole. The water flows outward from the high-flow nozzle 10 through the flow orifice. Conversely, if a smaller flow rate is required, the first insertion rod 8 is removed from the insertion slot 7, which releases the water flow restriction of the small-diameter spherical guide 15, allowing the water to flow outward through the low-flow nozzle 11, thus controlling the flow rate. The first sealing ring 19, the second sealing ring 20, and the O-ring 5 installed in the device ensure the overall water flow sealing. Water sealant is applied to the connection points where the water flows, ensuring the overall water flow sealing of the device and improving the production continuity of the nozzles.

[0025] like Figures 1-4As shown, the sealing tube 2 is fixedly installed on both sides of the main body 1, the threaded rod 4 is threaded into the inside of the sealing tube 2, the octagonal piece 3 is fixedly installed on one end of the threaded rod 4, the bearing 18 is rotatably installed on the other end of the threaded rod 4 away from the octagonal piece 3, the rubber clip 17 is fixedly installed on one side surface of the bearing 18, a first sealing ring 19 is installed on one end of the sealing tube 2, and a second sealing ring 20 is installed on the other end of the sealing tube 2 away from the first sealing ring 19. The first sealing ring 19 and the second sealing ring 20 can ensure to the greatest extent that when the threaded rod 4 inside the sealing tube 2 is threaded, the water seeping out of the main body 1 will not spray outward, thus ensuring the overall sealing performance of the device.

[0026] like Figures 1-4 As shown, the housing 6 is fixedly installed at one end of the main body 1, and the insertion groove 7 is fixedly installed on the surface of the housing 6. The first insertion rod 8 and the second insertion rod 9 are respectively inserted into the two insertion grooves 7. The triangular piece 14 is fixedly installed on one side surface of the housing 6. The inside of the insertion grooves 7 is coated with liquid sealant and a sealing rubber ring is installed at the insertion point to maximize the control of the water flow by the first insertion rod 8 and the second insertion rod 9.

[0027] Example 2: A modular nozzle that is easy to replace, such as Figures 1-4 As shown, a small-diameter spherical guide 15 is installed at one end of the first plug rod 8, and a large-diameter spherical guide 16 is installed at one end of the second plug rod 9. Several snap-fit ​​interfaces 13 are provided on the surface of the housing 6. The housing 6 is snapped with the guide plate 12 through the snap-fit ​​interfaces 13. The presence of the housing 6 can limit the installation position of the small-diameter guide 15 and the large-diameter spherical guide 16 inside. The large-flow nozzle 10 installed on the guide plate 12 corresponds to the position of the large-diameter spherical guide 16, and the small-flow nozzle 11 corresponds to the position of the small-diameter spherical guide 15, so that it achieves the effect of single-channel sealed transportation and better realizes the precise control of the water flow.

[0028] like Figures 1-4 As shown, a high-flow nozzle 10 is installed at one end of the flow guide plate 12, and a low-flow nozzle 11 is installed on one side of the high-flow nozzle 10. Both the high-flow nozzle 10 and the low-flow nozzle 11 are fixedly installed on the surface of the flow guide plate 12. An O-ring 5 is installed on the surface of the housing 6. A small-diameter spherical flow guide 15 is fixedly installed at one end of the first plug rod 8, and a large-diameter spherical flow guide 16 is fixedly installed at one end of the second plug rod 9. The presence of the O-ring 5 can ensure the sealing of the liquid transport inside the housing 6.

[0029] 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.
