Description

Technical Field

[0001] This utility model relates to the field of connector technology for connection and reinforcement, specifically an anti-loosening connector for a massage nozzle. Background Technology

[0002] With rapid economic development and the continuous improvement of people's living standards, people's demands for quality of life and leisure experiences are also increasing. In modern home and bathroom design, bathtub massage nozzles have become an indispensable feature. These massage nozzles provide users with a unique experience of full-body massage and relaxation by spraying bubbles that mix water and air. Generally, a bathtub massage nozzle consists of a nozzle body, which usually has a water inlet pipe and an air inlet pipe on its side to achieve the adaptation and coordination of water and air.

[0003] Currently, the connection between the water inlet pipe of the massage nozzle and the water inlet hose is generally achieved by direct insertion or by clamp fixation. In practical applications, to enhance sealing and connection stability, adhesive is usually applied to the interface and a metal clamp is fitted to prevent the hose from detaching under water pressure. However, the clamp structures used in existing technologies mostly only provide basic sealing and reinforcement, and cannot provide sufficient protection against detachment in cases of adhesive failure or sudden changes in water pressure. When there are high water pressure fluctuations or external pulling forces in the operating environment, traditional connection methods are prone to hose slippage, leakage, and even damage to the nozzle assembly, seriously affecting the reliability and lifespan of the equipment. Therefore, it is necessary to provide a connector with better sealing performance and detachment prevention capabilities. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-loosening connector for massage nozzles, which effectively improves the defects in sealing and fixing of some traditional massage nozzle hose connections.

[0005] A non-loosening connector for a massage nozzle is used to seal and fix the connection point after the massage nozzle is connected to the hose. It includes a bendable strip, semi-circular parts disposed at both ends of the strip, and fastening parts. The strip is used to wrap around the massage nozzle. The two semi-circular parts are used to be symmetrically fastened to the outside of the hose after the strip is bent. The fastening parts are used to ensure that the two semi-circular parts are tightly connected when they are fastened to the outside of the hose.

[0006] Preferably, the outer sides of the two semi-circular parts are provided with matching external threads, the fastening part is a connector lock nut, and the inner side of the connector lock nut is provided with an internal thread that mates with the external threads.

[0007] Preferably, the semi-circular part has a plurality of claws extending from the end away from the strip part, and when the fastening part is fastened to the outside of the two semi-circular parts, the claws are sleeved in the connector lock nut.

[0008] Preferably, the inner side of the claw is provided with multiple strip-shaped protrusions.

[0009] Preferably, the fastening components are buckles and slots, and multiple matching buckles and slots are respectively provided on the opposite end faces of the two semi-circular components when they are fastened together.

[0010] Preferably, the fastening component is a locking screw, and the opposite end faces of the two semi-circular components are provided with mounting portions. The mounting portions are provided with threaded mounting holes. When the two semi-circular components are fastened together, the threaded mounting holes of the two semi-circular components are opposite to each other, and the locking screw is installed into the threaded mounting holes to achieve a tight fastening of the two semi-circular components.

[0011] Preferably, the inner diameter of the two semi-circular parts after they are fastened together is equal to or slightly smaller than the outer diameter of the hose.

[0012] Preferably, a rubber strip is provided on the inner side of the two semi-circular parts.

[0013] Preferably, the outer side of the anti-loosening connector for the massage nozzle is provided with a UV-resistant layer and a wear-resistant layer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model provides an anti-loosening connector for a massage nozzle. Through the organic cooperation of a bendable strip, two semi-circular ends, and a fastening element, it achieves comprehensive coverage and uniform locking of the connection between the water inlet pipe and the flexible hose of the massage nozzle. This ensures easy installation while significantly improving sealing and anti-loosening performance. Specifically, the bendable strip fits tightly against the outside of the massage nozzle, and the semi-circular ends, after being bent, symmetrically fasten to the outside of the flexible hose, forming a 360° encircling structure. The fastening elements apply continuous pressure to the two semi-circular ends after they are fastened, ensuring a firm engagement and preventing the hose from loosening due to water pressure fluctuations or external pulling. This anti-loosening connector for massage nozzles requires no additional tools; installation is completed in just three steps: wrapping, aligning, and tightening, greatly simplifying maintenance and replacement procedures. Simultaneously, the curved fit between the strip-shaped and semi-circular components ensures a highly reliable seal at the interface, effectively preventing loosening and leakage under pressure or adhesive failure at the hose connection. Furthermore, the anti-loosening connector for massage nozzles can be manufactured in one piece using injection molding or stamping processes, resulting in low manufacturing costs, reusability, corrosion resistance, and durability. Therefore, this anti-loosening connector for massage nozzles not only significantly improves the safety and reliability of massage nozzle hose connections but also provides a more convenient and efficient installation experience and a longer product lifespan.

[0022] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] Example 1:

[0024] See Figures 1-4 This embodiment 1 provides an anti-loosening connector for a massage nozzle 10, used to seal and fix the connection point after the massage nozzle 10 is connected to the hose 60. It includes a bendable strip 20, semi-circular parts 30 disposed at both ends of the strip 20, and fastening parts. The strip 20 is used to wrap around the massage nozzle 10. The two semi-circular parts 30 are used to be symmetrically fastened to the outside of the hose 60 after the strip 20 is bent. The fastening parts are used to make the two semi-circular parts 30 tightly connected when they are fastened to the outside of the hose 60.

[0025] Specifically, the outer sides of the two semi-circular parts 30 are provided with matching external threads 31, and the fastening part is a connector lock nut 50. The inner side of the connector lock nut 50 is provided with an internal thread that mates with the external threads 31. When installation is required, the strip 20 is bent around the massage nozzle 10 and bent to the water inlet pipe 11 of the massage nozzle 10. Since a hose 60 is installed at the water inlet pipe 11, the two semi-circular parts 30 fit against the outside of the hose 60. Then, by screwing in the connector lock nut 50, the connector lock nut 50 and the internal thread engage to firmly install the two semi-circular parts 30 onto the outside of the hose 60, thereby achieving a firm fixation and efficient seal of the hose 60. By cooperating with the lateral pulling force provided by the massage nozzle 10 to the strip 20, the hose 60 is prevented from slipping or leaking under high water pressure impact or external pulling force. It should be noted that this structure, through the engagement of the external thread 31 and the internal thread, ensures that the semi-circular part 30 applies a uniform radial clamping force to the hose 60. Simultaneously, the threaded connection method offers high reliability, is not prone to loosening, and resists the risk of loosening caused by vibration and impact. After installation, it can be quickly disassembled simply by loosening the connector lock nut 50, greatly improving the convenience of maintenance and replacement. Furthermore, this structure can be installed without additional tools, meeting the needs of rapid on-site assembly while ensuring long-term sealing durability.

[0026] Preferably, the semi-circular part 30 has a plurality of claws 40 extending from its end away from the strip part 20. When the fastening member is fastened to the outside of the two semi-circular parts 30, the claws 40 are fitted inside the connector lock nut 50. Further, the inner side of the claws 40 is provided with a plurality of strip-shaped protrusions 41. When the fastening member, i.e., the connector lock nut 50, is tightened, the claws 40 extending from the end of the semi-circular part 30 abut against the outer side of the claws 40 through the connector lock nut 50, so that the inner side of the claws 40 can be tightly fitted to the surface of the hose 60, realizing multi-point engagement of the hose 60; the strip-shaped protrusions 41 on the inner side of the claws 40 further form a high-friction engagement with the outer diameter surface of the hose 60, so that the claws 40 are firmly gripped to the outside of the hose 60 under the pressure of the connector lock nut 50. Therefore, the design of the claw 40 not only provides strong locking force in the radial direction, effectively preventing the hose 60 from slipping off under high water pressure impact or external pulling, but also ensures that the surface of the hose 60 is subjected to uniform force through the multi-point contact between the strip protrusion 41 and the claw 40, avoiding damage and leakage caused by local stress concentration.

[0027] Preferably, the inner diameter of the two semi-circular parts 30 after fastening is equal to or slightly smaller than the outer diameter of the hose 60, achieving a slight interference fit with the outer surface of the hose 60 after fastening. This interference fit allows the semi-circular parts 30 to apply a constant and uniform radial compressive force to the hose 60 during fastening, further improving the sealing performance of the joint and effectively preventing leakage under water pressure. Simultaneously, the appropriate interference fit is achieved through the elastic deformation of the hose 60 during installation, ensuring not only stability and vibration resistance after locking but also enhancing the hose 60's resistance to pull-out, preventing slippage or detachment under high flow rates or external forces.

[0028] Preferably, rubber strips are provided on the inner sides of the two semi-circular parts 30. The high coefficient of friction of the rubber strips can significantly improve the adhesion between the hose 60 and the semi-circular parts, preventing relative slippage during water pressure fluctuations or external pulling.

[0029] Preferably, the massage nozzle 10 has an ultraviolet-resistant layer and a wear-resistant layer on the outer side of the anti-loosening connector. This effectively prevents surface aging, fading, embrittlement, or powdering, and significantly improves the weather resistance of the connector in humid environments. At the same time, the wear-resistant layer can withstand repeated mechanical friction and scratches, effectively avoiding surface scratches and wear during daily use or cleaning, and greatly extending the overall service life of the anti-loosening connector.

[0030] This utility model provides an anti-loosening connector for a massage nozzle 10. Through the organic cooperation of a bendable strip 20, two semi-circular parts 30, and a fastening member, it achieves all-round coverage and uniform locking of the connection between the water inlet pipe 11 and the hose 60 of the massage nozzle 10, thereby ensuring easy installation while significantly improving sealing and anti-loosening performance. Specifically, the bendable strip 20 can tightly fit the outer side of the massage nozzle 10, and the semi-circular parts 30, after being bent, symmetrically fasten to the outer side of the hose 60, forming a 360° encircling structure; the fastening member applies a continuous clamping force to the two semi-circular parts 30 after they are fastened, so that the two semi-circular parts 30 are firmly engaged, preventing the hose 60 from loosening due to water pressure fluctuations or external pulling. The anti-loosening connector for the massage nozzle 10 requires no additional tools; installation is completed in just three steps: wrapping, aligning, and fastening, greatly simplifying maintenance and replacement procedures. Simultaneously, the curved fit between the strip-shaped component 20 and the semi-circular component 30 ensures a highly reliable seal at the interface, effectively preventing loosening and leakage at the hose 60 connection point due to glue failure or high pressure (traditional methods using a separate clamp may cause it to move along with the hose 60 due to excessive water pressure, leading to hose 60 detachment; the massage nozzle 10 itself provides tension to prevent displacement of the anti-loosening connector, thus preventing hose 60 from detaching). Furthermore, the anti-loosening connector for the massage nozzle 10 can be molded in one piece using injection molding or stamping processes, resulting in low manufacturing costs, reusability, corrosion resistance, and durability. Therefore, this anti-loosening connector for the massage nozzle 10 not only significantly improves the safety and reliability of the massage nozzle 10 hose 60 connection but also provides a more convenient and efficient installation experience and a longer product lifespan.

[0031] Example 2:

[0032] This embodiment 2 is largely the same as embodiment 1, except that in this embodiment 2, the fastening components are buckles and slots. Multiple matching buckles and slots are respectively provided on the opposite end faces of the two semi-circular components when they are fastened. When the two semi-circular components are fastened, simply aligning the buckles at both ends with the slots and applying moderate pressure achieves a quick "click" lock, eliminating the need for rotation or additional tightening tools. This significantly simplifies the installation process and shortens assembly time. Simultaneously, the multi-point buckle and slot engagement design ensures structural stability and tensile strength after fastening. When the hose is subjected to water pressure impact or external pulling, the buckle engagement points generate reliable mechanical clamping force, preventing the semi-circular components from loosening or separating.

[0033] Example 3:

[0034] This embodiment 3 is largely the same as embodiment 1, except that in this embodiment 1, the fastening component is a locking screw, and the opposite end faces of the two semi-circular components are provided with mounting portions. The mounting portions are provided with threaded mounting holes. When the two semi-circular components are fastened together, the threaded mounting holes of the two semi-circular components are opposite each other, and the locking screw is installed into the threaded mounting holes to achieve a tight fastening of the two semi-circular components. This achieves a tight fastening and fixation of the installation part of the hose, effectively preventing the hose connection from loosening and leaking under high pressure due to glue failure.

[0035] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
