[0029] Example 1

[0030] like Figure 1-3 As shown, the anti-loosening connection structure for faucets proposed in this utility model includes a connector 1, an extension tube 8, a housing, and a button;

[0031] Connector 1 is the water outlet end of the faucet body; wherein, a boss 12 is provided on the inner side of connector 1, and a sealing gasket 11 connected to the water outlet pipe 4 is provided on the top of the boss 12, which is used to seal the water outlet pipe 4 and connector 1 after the water outlet pipe 4 is installed.

[0032] The housing is fitted onto the outside of the connector 1 and extends to the inside of the connector 1, where it is movably connected to the bottom end of the outlet pipe 4.

[0033] The extension tube 8 is located at the top of the connector 1, and the outer side of the extension tube 8 is provided with a spring piece 5 for limiting the housing in use.

[0034] The button is located inside the housing and on the side of the spring piece 5, with one end extending through the housing to the outside of the housing.

[0035] In this embodiment, by sleeved on the outside of the water outlet pipe 4 and inserted into the inside of the connector 1, the housing is connected to the connector 1 and extends into the inside of the connector 1 to limit the position of the water outlet pipe 4 in the connector 1, thus sealing the connection between the water outlet pipe 4 and the connector 1. At the same time, the housing applies pressure to the spring piece 5, causing one end of the spring piece 5 to bend and become elastic. The elasticity of the spring piece 5 engages one end with the housing, thus limiting the position of the housing and preventing it from loosening on the connector 1, and providing a good anti-loosening effect. Meanwhile, the bending of one end of the spring piece 5 is controlled by a button, causing the spring piece 5 to separate from the housing and the housing to separate from the connector 1, making the disassembly of the housing convenient.

[0036] Example 2

[0037] like Figure 2-3 As shown, the faucet spout anti-loosening connection structure proposed in this utility model differs from that in Embodiment 1 in that the housing includes a connecting shell 2, a sleeve 6, and a limiting tube 7.

[0038] The connecting shell 2 is fitted onto the outside of the connector 1 and extends upwards from the connector 1;

[0039] The sleeve 6 is located at the inner top of the connecting shell 2 and on the outer side of the extension tube 8; wherein, at least one mounting hole 15 is provided on the inner side of the sleeve 6, and the spring piece 5 is arranged at an angle on the outer side of the extension tube 8, so that one end of the spring piece 5 can move towards the inner side of the mounting hole 15 by its own elastic force during use and be accommodated in the mounting hole 15.

[0040] The limiting tube 7 is inserted into the inside of the extension tube 8 and connected to the bottom and top of the outlet tube 4. The top of the tube is located above the extension tube 8 and connected to the top of the connecting shell 2. It is used to limit the position of the connecting shell 2 on the connector 1 during use.

[0041] In an optional embodiment, the bottom end of the sleeve 6 has a chamfer, which is used to bend the end of the spring piece 5 towards the outer wall of the extension tube 8 when the sleeve 6 contacts one end of the spring piece 5, so that the spring piece 5 can be easily moved to the inner side of the sleeve 6, so that the spring piece 5 generates an outward elastic force, ensuring that the end of the spring piece 5 can move into the mounting hole 15.

[0042] In an optional embodiment, the inner bottom end of the connecting shell 2 is provided with a threaded groove 9, and the outer side of the connector 1 is provided with an external thread 10. The dimensions of the threaded groove 9 and the external thread 10 are arranged to match each other, so as to install the connecting shell 2 on the connector 1 during use.

[0043] In this embodiment, the limiting tube 7 is sleeved on the outside of the water outlet pipe 4. When the water outlet pipe 4 is inserted into the inside of the connector 1, the limiting tube 7 is inserted into the inside of the connector 1 and the extension tube 8. At the same time, the limiting tube 7 drives the connecting shell 2 to be sleeved on the connector 1. By rotating the connecting shell 2, the connecting shell 2 is connected to the external thread 10 through the threaded groove 9. As the connecting shell 2 gradually moves down through the threaded groove 9 and the external thread 10, the chamfer of the sleeve 6 contacts and guides the end of the spring piece 5 to bend, so that the spring piece 5 moves to the inside of the sleeve 6. When the connecting shell 2 moves to the preset position, the connecting shell 2 drives the limiting tube 7 to press the water outlet pipe 4, improving the sealing effect. One end of the spring piece 5 enters the mounting hole 15 through the elastic force and connects with the button body 3, so that the position of the connecting shell 2 is limited, so as to avoid the connecting shell 2 from loosening after long-term use. At the same time, the button body 3 controls the bending of the spring piece 5, so that the end of the spring piece 5 slides and connects with the inner wall of the sleeve 6, making the disassembly of the connecting shell 2 more convenient.

[0044] Example 3

[0045] like Figure 3 As shown, the faucet spout anti-loosening connection structure proposed in this utility model differs from that in Embodiment 1 in that the button includes a button body 3 and a limiting block 14.

[0046] The button body 3 is installed inside the mounting hole 15, with one end extending through the connecting shell 2 to the outside of the connecting shell 2, and the other end being movably connected to the mounting hole 15.

[0047] Limiting blocks 14 are located on both sides of the other end of the button body 3 and are connected to the sleeve 6.

[0048] In an optional embodiment, a limiting groove 13 is provided on the inner side of the sleeve 6 and on both sides of the mounting hole 15. When the limiting block 14 is installed in conjunction with the sleeve 6, the limiting block 14 is accommodated in the limiting groove 13.

[0049] In this embodiment, the button body 3 is installed inside the mounting hole 15 and connected to one end of the spring piece 5. When the button body 3 moves inside the mounting hole 15, it can drive one end of the spring piece 5 to bend, making the disassembly of the connecting shell 2 more convenient. At the same time, through the cooperation of the limiting groove 13 and the limiting block 14, when the spring piece 5 drives the button body 3 to move outward from the mounting hole 15, it limits the button body 3 and prevents the button body 3 from falling off due to excessive movement.

[0050] In this invention, the limiting tube 7 is sleeved on the outside of the outlet pipe 4. When the outlet pipe 4 is installed inside the connector 1, the limiting tube 7 is inserted into the inside of the connector 1 and the extension pipe 8. At the same time, the limiting tube 7 drives the connecting shell 2 to be sleeved on the outside of the connector 1, and rotates the connecting shell 2 so that the connecting shell 2 is connected to the external thread 10 through the engagement of the threaded groove 9. As the connecting shell 2 gradually moves down through the threaded groove 9 and the external thread 10, the chamfer of the sleeve 6 contacts and guides the end of the spring piece 5 to bend, so that the spring piece 5 moves to the inside of the sleeve 6. When the connecting shell 2 moves to the preset position, the connecting shell 2 drives the limiting tube 7 to engage with the outlet pipe 4. Pressing down, while one end of the spring piece 5 enters the mounting hole 15 through elastic force and drives the button body 3 to move outward of the connecting shell 2, so that the connecting shell 2 is positioned by the cooperation of the spring piece 5 and the mounting hole 15, and by pressing the button body 3, it will move towards the extension tube 8 inside the mounting hole 15, so that the button body 3 drives one end of the spring piece 5 to bend towards the extension tube 8 and separate from the mounting hole 15, so that the connecting shell 2 and the connector 1 are disassembled. At the same time, through the cooperation of the limiting groove 13 and the limiting block 14, when the spring piece 5 drives the button body 3 to move outward of the connecting shell 2 in the mounting hole 15, it limits the button body 3.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
