Description

Technical Field

[0001] This utility model relates to the field of connector technology for connection and reinforcement, specifically a snap-fit ​​anti-loosening connector. 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 falling off 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 a snap-fit ​​anti-loosening connector, which effectively improves the defects in sealing and fixing of some traditional massage nozzle hose connections.

[0005] A snap-fit ​​anti-loosening connector is used to seal and fix the connection point after the massage nozzle is connected to the hose. Its features include an anti-loosening connector base and an anti-loosening connector cap. One end of the anti-loosening connector base is provided with a first connecting part, and the top surface of the other end of the anti-loosening connector base is rotatably provided with the anti-loosening connector cap. A snap-fit ​​structure is provided between the anti-loosening connector base and the anti-loosening connector cap, and a second connecting part is provided between the anti-loosening connector base and the anti-loosening connector cap.

[0006] Preferably, the first connecting portion and the second connecting portion are arranged at a predetermined angle.

[0007] Furthermore, the first connecting portion and the second connecting portion are arranged perpendicularly.

[0008] Preferably, the first connecting part is a through hole that passes through one end of the anti-detachment connector base.

[0009] Preferably, the second connecting part includes a semi-circular arc through groove recessed on the side of the anti-detachment connector base near the anti-detachment connector cover and facing away from the anti-detachment connector cover, and a semi-circular arc through groove recessed on the side of the anti-detachment connector cover near the anti-detachment connector base and facing away from the anti-detachment connector base. When the anti-detachment connector cover and the anti-detachment connector base are fastened together, the two semi-circular arc through grooves are joined to form a circular through groove.

[0010] Preferably, both of the inner walls of the semi-circular arc through grooves are provided with multiple raised spiral ribs.

[0011] Preferably, the anti-detachment connector cover includes an anti-detachment connector cover body and a connecting portion disposed at one end of the anti-detachment connector cover body. The connecting portion and the anti-detachment connector base are provided with the fastening structure. The end of the anti-detachment connector cover body away from the connecting portion is rotatably connected to a mounting base disposed on the anti-detachment connector base by a pin.

[0012] Furthermore, the top of the anti-detachment connector cover body near the connecting part and the side of the anti-detachment connector base away from the anti-detachment connector cover body are both provided with arc-shaped protrusions.

[0013] Preferably, the fastening structure includes a fastening structure in which a fastening groove and a fastening head cooperate, or a fastening structure in which the anti-detachment connector cover and the anti-detachment connector base are provided with corresponding threaded holes and are tightened with screws.

[0014] Preferably, the inner diameter of the circular groove is equal to or slightly smaller than the outer diameter of the hose.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model provides a snap-fit ​​anti-loosening connector, which includes an anti-loosening connector base and an anti-loosening connector cap. Firstly, a first connecting part at one end of the anti-loosening connector base and a second connecting part at the other end of the anti-loosening connector base, which mates with the anti-loosening connector cap, are respectively fitted onto the nozzle body of the massage nozzle and the connection between the water inlet pipe and the hose during installation. When the hose is subjected to water pressure impact and external pulling force, the tight mechanical connection between the first and second connecting parts ensures that the snap-fit ​​anti-loosening connector is securely installed at the hose and massage nozzle, preventing movement and greatly improving the hose's sealing effect, effectively preventing leakage and loosening due to seal failure. Secondly, the openable and closable connection design of the anti-loosening connector cap and the anti-loosening connector base not only facilitates quick and accurate alignment and adjustment during installation, disassembly, and maintenance, but also reduces the risk of improper connection due to complex operation. Therefore, this snap-on anti-loosening connector solves the problem that traditional clamps are prone to loosening of the connection when the glue fails. It can also extend the service life of the equipment under long-term and frequent use, ensuring that the massage nozzle system maintains excellent safety, stability and durability in high water pressure and constantly changing use environments.

Detailed Implementation

[0024] 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.

[0025] See Figures 1-5 This embodiment provides a snap-on anti-loosening connector for sealing and fixing the connection point after the massage nozzle is connected to the hose 13. It includes an anti-loosening connector base 10 and an anti-loosening connector cover 20. One end of the anti-loosening connector base 10 is provided with a first connecting part 30, and the top surface of the other end of the anti-loosening connector base 10 is rotatably provided with the anti-loosening connector cover 20. A snap-fit ​​structure is provided between the anti-loosening connector base 10 and the anti-loosening connector cover 20, and a second connecting part 40 is provided between the anti-loosening connector base 10 and the anti-loosening connector cover 20.

[0026] Preferably, the first connecting portion 30 and the second connecting portion 40 are arranged at a predetermined angle, thereby adapting to different nozzle structural layouts and enhancing the flexibility and adaptability of the connector when connecting to the massage nozzle. See also the accompanying drawings. Figure 4 It is understood that in traditional massage nozzles, the water inlet pipe 11 and the nozzle body 12 are arranged perpendicularly. That is, when the first connecting part 30 is fitted onto the nozzle body 12 in this application, the second connecting part 40 must be perpendicular to the first connecting part 30 to achieve the connection between the water inlet pipe 11 and the hose 13. Therefore, in this embodiment, the first connecting part 30 and the second connecting part 40 are arranged perpendicularly.

[0027] Preferably, the first connecting part 30 is a through hole penetrating one end of the anti-detachment connector base 10. Specifically, the end of the through hole is set to be semi-circular, thus making the through hole U-shaped. The first connecting part 30 is sleeved on the nozzle body 12, thereby forming a stable fit between the snap-on anti-detachment connector and the nozzle. With the help of the nozzle itself, when the hose 13 is detached, the snap-on anti-detachment connector can maintain a stable position. The second connecting part 40 will provide a stable frictional force opposite to the direction of hose 13 detachment, thereby ensuring that the hose 13 will not detach, thus enhancing the stability and anti-detachment capability of the overall structure.

[0028] Preferably, the second connecting portion 40 includes a semi-circular arc groove 41 recessed on the side of the anti-detachment connector base 10 near the anti-detachment connector cover 20 and facing away from the anti-detachment connector cover 20, and a semi-circular arc groove 41 recessed on the side of the anti-detachment connector cover 20 near the anti-detachment connector base 10 and facing away from the anti-detachment connector base 10. When the anti-detachment connector cover 20 is fastened to the anti-detachment connector base 10, the two semi-circular arc grooves 41 are joined to form a circular groove. The circular groove can tightly cover the outside of the hose 13 from the water inlet pipe 11 of the massage nozzle. Therefore, while enabling quick installation, the second connecting part 40 utilizes the radial clamping force generated after the anti-detachment connector cap 20 and the anti-detachment connector base 10 are fastened together to effectively enhance the tightness and sealing of the connection between the hose 13 and the water inlet pipe 11. At the same time, its cooperation with the first connecting part 30 prevents the hose 13 from loosening or falling off due to water pressure fluctuations, vibrations or external pulling during use.

[0029] Preferably, multiple raised spiral ribs 42 are provided on the inner sidewalls of both semi-circular arc through grooves 41. When the anti-detachment connector cap 20 is engaged with the anti-detachment connector base 10, these spiral ribs 42 encircle and press tightly around the surface of the hose 13, achieving a more stable mechanical fixation effect. While providing multi-point contact support, the spiral ribs 42 also enhance the friction of the hose 13 in the circular through groove, preventing the hose 13 from slipping or loosening due to water pressure impact, external pulling force, or frequent use. In addition, the spiral rib structure 42 can also provide pressure to the hose 13 to achieve reliable sealing performance, significantly improving the sealing effect and anti-detachment performance at the connection, thereby improving the stability and safety of the device in complex water pressure environments. In this embodiment, the spiral ribs 42 can be made of materials such as rubber.

[0030] Preferably, the anti-detachment connector cover 20 includes an anti-detachment connector cover body 21 and a connecting portion 22 disposed at one end of the anti-detachment connector cover body 21. The connecting portion 22 and the anti-detachment connector base 10 are provided with the fastening structure. The end of the anti-detachment connector cover body 21 away from the connecting portion 22 is rotatably connected to a mounting seat disposed on the anti-detachment connector base 10 via a pin 50. Therefore, the anti-detachment connector cover 20 and one end of the anti-detachment connector base 10 form a hinge-like connection structure. This hinge-like structure allows the anti-detachment connector cover 20 to open and rotate around the axis of the pin 50, facilitating flip-opening operations during installation or disassembly. The other end is selectively locked and fixed through the fastening structure, making the assembly process simpler and more reliable, and improving the ease of operation and user-friendliness of the connector.

[0031] Preferably, the fastening structure includes a fastening structure in which the slot 24 and the buckle 23 cooperate, or a fastening structure in which the anti-detachment connector cover 20 and the anti-detachment connector base 10 are provided with corresponding threaded holes and are tightened with screws. Specifically, when the fastening structure adopts the fastening structure in which the slot 24 and the buckle 23 cooperate, the side of the anti-detachment connector base 10 is provided as the slot 24, and the connecting part 22 is provided as the buckle 23. After pressing the anti-detachment connector cover 20 to close onto the anti-detachment connector base 10, the buckle 23 provided on the anti-detachment connector cover 20 will fasten to the slot 24 on the anti-detachment connector base 10, thereby forming a reliable fastening and fixing state, realizing quick locking and fastening, and the installation and disassembly operations can be completed without additional tools, greatly improving the convenience and efficiency of use. On the other hand, when the fastening structure is provided with corresponding threaded holes on the anti-detachment connector cover 20 and the anti-detachment connector base 10 and tightened with screws, the anti-detachment connector cover 20 and the anti-detachment connector base 10 can be tightly fastened by screwing the screws into the threaded holes provided on the anti-detachment connector cover 20 and the anti-detachment connector base 10.

[0032] Furthermore, the top of the anti-detachment connector cover body 21 near the connecting part 22 and the side of the anti-detachment connector base 10 away from the anti-detachment connector cover body 21 are both provided with arc-shaped protrusions 25, which facilitates pressing during fastening.

[0033] Preferably, the inner diameter of the circular groove is equal to or slightly smaller than the outer diameter of the hose 13. This dimensional fit design allows the hose 13 to be tightly enclosed by the circular groove during installation, creating a reliable compression effect. Because the inner diameter is equal to or slightly smaller than the outer diameter of the hose 13, after the anti-detachment connector cap 20 and the anti-detachment connector base 10 are engaged, the hose 13 can be subjected to uniform radial compression within the circular groove, further improving the sealing and anti-detachment properties at the interface between the hose 13 and the water inlet pipe 11.

[0034] It should be noted that after the hose 13 is installed at the water inlet pipe 11 of the massage nozzle, the snap-on anti-loosening connector is first inserted from the bottom of the massage nozzle, that is, the first connecting part 30 is put on the nozzle body 12 of the massage nozzle, and the anti-loosening connector cover 20 is in the open state. The semi-circular arc through groove 41 on the anti-loosening connector base 10 is fitted on the outside of the hose 13. Then, the anti-loosening connector cover 20 is fastened downward with the anti-loosening connector base 10. At this time, the semi-circular arc through groove 41 on the anti-loosening connector cover 20 is fitted on the outside of the hose 13. After the anti-loosening connector cover 20 and the anti-loosening connector base 10 are fastened, the hose 13 is tightly fastened by the second connecting part 40, thereby making the hose 13 tightly connected to the water inlet pipe 11.

[0035] This utility model provides a snap-on anti-loosening connector, which includes an anti-loosening connector base 10 and an anti-loosening connector cap 20. Firstly, a first connecting part 30 at one end of the anti-loosening connector base 10 and a second connecting part 40 at the other end of the anti-loosening connector base 10, which cooperates with the anti-loosening connector cap, are respectively fitted onto the nozzle body 12 of the massage nozzle and the connection between the water inlet pipe 11 and the hose 13 during installation. When the hose 13 is subjected to water pressure impact and external pulling force, the tight mechanical connection between the first connecting part 30 and the second connecting part 40 ensures that the snap-on anti-loosening connector is tightly installed on the hose 13 and the massage nozzle, preventing movement and greatly improving the sealing effect of the hose 13, effectively preventing leaks caused by seal failure. Leakage and loosening of connections (traditional installation of a single clamp may cause it to move along with the hose 13 due to excessive water pressure, leading to hose 13 detachment; this application essentially sets a limit on the snap-on anti-loosening connector through the massage nozzle, thus preventing the snap-on anti-loosening connector from moving, and the hose 13 will not detach due to friction with the snap-on anti-loosening connector, etc.); secondly, the openable and closable connection design of the anti-loosening connector cap 20 and the anti-loosening connector base 10 not only facilitates quick and accurate alignment and adjustment during installation, disassembly, and maintenance, but also reduces the risk of improper connection due to complex operation. Therefore, this snap-on anti-loosening connector solves the problem of loosening of the connection part 22 due to glue failure in traditional clamps, and can extend the service life of the equipment under long-term frequent use, ensuring that the massage nozzle system maintains excellent safety, stability, and durability in high water pressure and constantly changing operating environments.

[0036] 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.
