For this reason, the prior art has a height-adjustable faucet, also known as a lifting faucet, which has a liftable lifting tube. The water outlet height is adjusted by lifting and lowering the lifting tube, thereby improving the user experience of the faucet. However, the lifting faucet of the prior art has the following shortcomings: it uses an O-ring to increase the movement friction of the lifting tube to achieve the purpose of lifting adjustment and positioning after lifting, but this method causes the lifting tube to be pulled up and down unsmoothly, and there will be a sense of jamming. Utility Model Content

[0003] The utility model aims at the technical problems existing in the prior art and provides a lifting faucet, which enables a lifting pipe to be lifted up and down smoothly without any jamming through structural improvement.

[0008] Furthermore, an adjustment boss is provided on the outer wall surface of the lining corresponding to the adjustment hole, and the adjustment boss extends into the adjustment hole.

[0009] Furthermore, the elastic member is an elastic pad or a spring, and the adjusting member is a set screw.

[0010] Furthermore, the inner wall surface of the liner is provided with a groove, the groove extends along the axial direction of the liner, and the groove is provided with openings at both ends of the axial direction of the liner respectively; the number of the groove is one, or the number of the groove is multiple, and the multiple grooves are distributed along the circumferential direction of the liner.

[0011] Furthermore, the inner wall surface of the outer shell is provided with a circle of limiting grooves, and the outer wall surface of the lining is provided with limiting ribs extending along its circumferential direction, and the limiting ribs are inserted into the limiting grooves to limit the axial movement of the lining relative to the outer shell; the number of the limiting ribs is multiple, and the multiple limiting ribs are distributed at intervals along the circumference of the lining.

[0012] Furthermore, the lifting tube and the shaft sleeve are rotationally matched so that the lifting tube can rotate around its axis.

[0013] Furthermore, the valve body part includes a valve body, a fixed tube, and the upper end of the fixed tube is fixedly connected to the valve body. The sleeve is located in the valve body and above the fixed tube. The lower end of the lifting tube extends into the fixed tube, and a clamping ring is sleeved on the outside of the lower end of the lifting tube. The outer diameter of the clamping ring is larger than the inner diameter of the sleeve to limit the lifting tube from detaching upward from the sleeve.

[0014] Furthermore, the water outlet assembly includes a water outlet elbow and a shower head, one end of the water outlet elbow is connected to the upper end of the lifting pipe, and the other end of the water outlet elbow is connected to the shower head.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. Since a sleeve is installed inside the valve body, the sleeve includes an inner liner, and the side wall of the inner liner is provided with an adjustment slot extending along its axial direction, so that the inner diameter of the inner liner is adjustable, and the inner liner embraces the lifting tube, so that the lifting tube can be adjusted up and down or maintained in an adjusted state. Therefore, the utility model can use the inner liner to stabilize the lifting tube so that the lifting tube will not shake during the movement.

The adjustment piece can extend into the adjustment hole and act on the liner to adjust the degree of holding the liner to the lifting tube, so that after the product of the utility model is used for a long time, the product may have the problem of failure of lifting and positioning. At this time, it is only necessary to tighten the adjustment piece to increase the degree of cooperation between the liner and the lifting tube and increase the degree of holding, so that the product can restore the positioning function and ensure that the lifting tube will not fall under the action of non-external force. In particular, an elastic piece is installed in the adjustment hole, and the adjustment piece acts on the liner by pushing the elastic piece, which can avoid the adjustment piece directly contacting the liner hard and causing the liner to be scratched or even damaged. The outer wall surface of the liner is provided with an adjustment boss corresponding to the adjustment hole, and the adjustment boss extends into the adjustment hole, so that the utility model can use the adjustment boss to limit the liner in the circumferential direction, play a role in stopping the rotation of the liner, and on the other hand, it can increase the strength of the liner at the position where the adjustment boss is located, and make it inconvenient to fix the adjustment position of the liner.

[0019] 4. The inner wall surface of the lining is provided with the groove, so that the utility model can utilize the groove to improve the deformation ability of the lining, so that the lining can be easily deformed and installed during installation, and on the other hand, the lining has a sewage discharge function. When there is dirt such as mud and sand on the lifting pipe, the dirt will be squeezed into the groove during movement, which will not affect the smoothness of the movement of the lifting pipe.

[0032] See also Figure 1-Figure 8 As shown, a lifting faucet of the utility model includes a valve body part and a lifting pipe 3. The lifting pipe 3 can be inserted into the valve body part in a liftable manner, and a water outlet assembly is provided at the upper end of the lifting pipe 3. A shaft sleeve 4 is installed inside the valve body part. The shaft sleeve 4 includes an inner liner 41. The side wall of the inner liner 41 is provided with an adjustment slit 411 extending along its axial direction so that the inner diameter of the inner liner 41 can be adjusted. The inner liner 41 surrounds the lifting pipe 3 so that the lifting pipe 3 can be adjusted up and down or maintained in an adjusted state. In addition, the lifting pipe 3 and the shaft sleeve 4 are rotationally matched so that the lifting pipe 3 can rotate around its axis, such as Figure 6 As shown, the arc arrow in the figure indicates the rotation direction of the lifting tube 3.

[0033] In this embodiment, the valve body part includes a valve body 1, a fixed pipe 2, the upper end of the fixed pipe 2 is fixedly connected to the valve body 1, the sleeve 4 is located in the valve body 1 and above the fixed pipe 2, the lower end of the lifting pipe 3 extends into the fixed pipe 2, and a clamping ring 7 is sleeved on the outer part of the lower end of the lifting pipe 3, the clamping ring 7 is C-shaped, and the outer diameter of the clamping ring 7 is larger than the inner diameter of the sleeve 4, so as to limit the lifting pipe 3 from upwardly separating from the sleeve 4. The water outlet assembly includes a water outlet elbow 31 and a shower head 32, one end of the water outlet elbow 31 is connected to the upper end of the lifting pipe 3, and the other end of the water outlet elbow 31 is connected to the shower head 32.

[0034] As a preferred embodiment, the shaft sleeve 4 of the utility model further includes a shell 42, and the liner 41 is sleeved in the shell 42, so as to limit the liner 41 by the shell 42 and solve the problem of assembling and fixing the liner 41. Since the liner 41 is provided with an adjustment slit 411, when assembling the liner 41, the liner 41 can be deformed inward by squeezing the liner 41 at a position outside the adjustment slit 411, so that the liner 41 can be smoothly installed in the shell 42.

[0035] like Figure 2-Figure 4 As shown, the housing 42 is provided with an adjustment hole 421, and the valve body 1 is partially threadedly connected with an adjustment piece corresponding to the adjustment hole 421. The adjustment piece can extend into the adjustment hole 421 and act on the liner 41 to adjust the degree of tightening of the liner 41 to the lifting pipe 3. The adjustment piece is specifically a set screw 5, such as Figure 8 As shown, but not limited to.

[0036] In this embodiment, an elastic member is installed in the adjustment hole 421, and the adjustment member (i.e., the set screw 5) acts on the lining 41 by pushing the elastic member, thereby preventing the set screw 5 from directly and rigidly contacting the lining 41 and causing the lining 41 to be scratched or even damaged. The elastic member is specifically an elastic pad 6, such as Figure 1 ,like Figure 8 As shown, but not limited to this, in other embodiments, the elastic member is a spring.

[0037] like Figure 2 , Figure 4 As shown, an adjusting boss 412 is provided on the outer wall surface of the liner 41 corresponding to the adjusting hole 421 of the shell 42, and the adjusting boss 412 extends into the adjusting hole 421. Therefore, when the set screw 5 pushes the elastic pad 6, the elastic pad 6 will directly act on the adjusting boss 412, so that the liner 41 can adjust the degree of holding the lifting tube 3. In addition, the utility model can also use the adjusting boss 412 to limit the liner 41 in the circumferential direction, play a role in stopping the liner 41 from rotating. The utility model can also increase the strength of the liner 41 at the position where the adjusting boss 412 is located, and make it inconvenient to fix the adjustment position of the liner 41.

[0038] like Figure 2As shown, the inner wall surface of the liner 41 is provided with a plurality of grooves 414, which are evenly distributed along the circumferential direction of the liner 41, and each groove 414 extends along the axial direction of the liner 41, and each groove 414 is provided with openings at both ends of the axial direction of the liner 41. On the one hand, the utility model can utilize the grooves 414 to improve the deformation ability of the liner 41, so that the liner 41 is easy to deform and install during installation, and on the other hand, the liner 41 has a sewage discharge function. When there is dirt such as mud and sand on the lifting pipe 3, the dirt will be squeezed into the groove 414 during the movement, and will not affect the smoothness of the movement of the lifting pipe 3. In other embodiments, the number of the groove 414 is one.

[0039] like Figure 2 As shown, the inner wall surface of the outer shell 42 is provided with a circle of limiting grooves 422, and the outer wall surface of the liner 41 is provided with limiting ribs 413 extending along its circumferential direction, and the limiting ribs 413 are inserted into the limiting grooves 422 to limit the axial movement of the liner 41 relative to the outer shell 42. There are multiple limiting ribs 413, and the multiple limiting ribs 413 are distributed at intervals along the circumference of the liner 41. Therefore, the limiting ribs 413 of the utility model are discontinuous convex ribs, which can achieve the effect of easy deformation installation during the installation process.

[0040] like Figure 1 As shown, the utility model also includes a valve core assembly 8 installed on the valve body 1, the valve core assembly 8 is composed of a valve core 82, a valve core seat 81, a pressure cap 83, a decorative nut 84, a handle 85, etc., and is installed in the valve body 1 from the lateral direction of the valve body 1. The valve core 82 is specifically a mixed valve core, preferably a thermostatic valve core, but not limited to this. In other embodiments, the valve core is a switch valve core, which only has the function of switching water. The valve core 82 is connected to a cold water inlet pipe 86, a hot water inlet pipe 87, and a mixed outlet pipe 88. The outlet end of the mixed outlet pipe 88 is connected to one end of a pull-out pipe 9, and the other end of the pull-out pipe 9 is connected to the lower end of the lifting pipe 3, and a counterweight hammer 10 is arranged on the pull-out pipe 9. In this way, when the lifting pipe 3 rises, the pull-out pipe 9 is pulled upward, and when the lifting pipe 3 descends, the pull-out pipe 9 falls under the gravity of the counterweight hammer 10, thereby ensuring that the lifting pipe 3 can be lifted and lowered normally. The utility model further comprises a locking nut assembly 20 for installing and fixing the valve body 1 .

[0041] The utility model provides a lifting faucet, wherein the adjustable height of the lifting pipe 3 is H, and the height of the shaft sleeve 4 is H1, and H1 is smaller than H. During the adjustment process, at any position within the adjustable height range of the lifting pipe 3, the lifting pipe 3 will remain at the current position without the action of external force, and will not fall, and can also achieve circumferential rotation to facilitate adjustment of the water outlet angle and water outlet position. The adjustment slit 411 of the lining 41 enables it to adjust the tightness of the shaft, solve the problem of over-tightening or over-loosening, and make the lifting pipe 3 smooth during axial movement or rotation, without jamming or shaking.

[0042] After the lifting faucet of the utility model has been used for a long time, the lifting tube 3 of the utility model may fail to position. At this time, it is only necessary to tighten the set screw 5 to make it push the elastic pad 6, and the elastic pad 6 presses the adjustment boss 412 of the lining 41 inward, thereby increasing the degree of fit between the lining 41 and the lifting tube 3, increasing the degree of tightening, restoring the positioning function of the product, and ensuring that the lifting tube 3 will not fall without the action of external force. Therefore, the utility model makes the product reach an ultra-long service life, and there will be no failure problem after long-term use.

[0043] The utility model provides a lifting faucet, and the unrelated parts are the same as the existing technology or can be implemented by using the existing technology.

[0044] The above embodiments are only used to further illustrate a lifting faucet of the utility model, but the utility model is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model fall within the protection scope of the technical solution of the utility model.
