[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0027] See also Figure 1-7 A pull-out tube structure 1, the pull-out tube structure 1 comprises an outer hose 11, an inner hose 12 and a return spring 13. The inner hose 12 is slidably arranged in the outer hose 11, the return spring 13 is arranged between the inner hose 12 and the outer hose 11, and the inner hose 12 comprises a retracted position and an extended position relative to the outer hose 11. In the retracted position, the overall length of the pull-out tube structure 1 is small, and in the extended position, the overall length of the pull-out tube is large. When the inner hose 12 moves from the retracted position to the extended position relative to the outer hose 11, the return spring 13 accumulates elastic force. The return spring 13 is arranged between the inner hose 12 and the outer hose 11, is not exposed to the outside, and can protect the return spring 13. The inner hose 12 moves between the extended position and the retracted position relative to the outer hose 11, and can play the role of a conventional pull-out tube, and does not require structures such as under-table weights. The outer hose 11 and the inner hose 12 are both hose structures. The overall structure is flexible and can be adapted to water outlet elbows of different shapes, etc. It has strong applicability, can play a good deformation role, and provides a good user experience.
[0028] The outer hose 11 includes a fixed end 111 and a free end 112. The inner hose 12 can extend or retract from the free end 112 of the outer hose 11. The fixed end 111 of the outer hose 11 is fixedly arranged, and the free end 112 can move relative to the free end 112. Therefore, when the inner hose 12 extends or retracts from the free end 112, the free end 112 can move with the movement of the inner hose 12, and the movement of the inner hose 12 will not feel stuck or unsmooth, which is no different from a conventional pull-out tube.
[0029] The inner hose 12 includes a sliding end 121 sliding inside the outer hose 11 and a water outlet end 122 located outside the free end 112 of the outer hose 11, and the water outlet end 122 is used to connect to the water outlet head 2. The two ends of the return spring 13 are respectively connected to the free end 112 of the outer hose 11 and the sliding end 121 of the inner hose 12. When in the extended position, the sliding end 121 is close to the free end 112, and the return spring 13 is compressed. The return spring 13 is connected at two relative moving positions of the inner hose 12 and the outer hose 11, and has a better effect.
[0030] In this embodiment, the sliding end 121 and the inner wall of the outer hose 11 are sealed and connected by a sealing ring 14. The sealing ring 14 can prevent water seepage and improve the sliding feel. The outer hose 11 and the inner hose 12 are connected, and the sealing ring 14 can prevent water from seeping into the gap between the inner hose 12 and the outer hose 11, thereby preventing water from affecting the return spring 13.
[0031] In this embodiment, the free end 112 of the outer hose 11 is provided with a first end sleeve 113, the sliding end 121 of the inner hose 12 is provided with a second end sleeve 123, and the two ends of the return spring 13 are respectively abutted between the first end sleeve 113 and the second end sleeve 123.
[0032] The utility model also provides a faucet, which includes the pull-out tube structure 1. The faucet also includes a faucet body 3, a water outlet pipe 4 and a water outlet head 2; the water outlet pipe 4 is arranged on the faucet body 3, the pull-out tube structure 1 is arranged in the water outlet pipe 4, the outer layer hose 11 is connected to the faucet body 3 or the water outlet pipe 4, the inner layer hose 12 is connected to the water outlet head 2, and the inner layer hose 12 slides relative to the outer layer hose 11 so that the water outlet head 2 is pulled and arranged on the water outlet pipe 4.
[0033] In this embodiment, the water outlet pipe 4 is rotatably arranged on the faucet body 3. The faucet body 3 includes a connection joint 31, and the water outlet pipe 4 is rotatably sleeved outside the connection joint 31; the upper end of the connection joint 31 includes a transfer port 32, and the fixed end 111 of the outer hose 11 is rotated on the transfer port 32, and the transfer port 32 is connected to the water source. The fixed end 111 of the outer hose 11 is limited by a clamping ring along the axial movement of the transfer port 32, and the fixed end 111 of the outer hose 11 can be rotated.
[0034] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
