Description

Technical Field

[0001] The present invention relates to the field of household products, and particularly to a clamping assembly, a clamping device and a shower pipe. Background Art

[0002] The existing fixed inner pipe structure has great limitations, the height of the top spray water outlet is not adjustable, resulting in a single product appearance and lack of versatility; to facilitate height adjustment, the lifting shower pipe usually uses the friction force after the support seat or lock nut is tightened to ensure that the upper shower pipe does not move up. One problem with this structure is that it is difficult to overcome the upward force generated by the back pressure with the friction force under high water pressure and high back pressure; second, the friction force decreases after long-term use and loosening; third, when the surface of the shower pipe is wet, the friction force will decrease, resulting in a risk that the upper pipe still moves up. And the height adjustment of the existing lifting shower pipe often requires a screwdriver or turning a knob to loosen or tighten the adjustment. First, the adjustment method is complex. Second, to ensure that it does not move up during adjustment, a large torque is required, and it is difficult to control the force during actual operation. Third, after repeated adjustment, the locking friction force will decrease, and there is a risk that the pipe fittings move up. Summary of the Invention

[0017] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solutions and their preferred embodiments of the present invention have the following beneficial effects due to the following technical means:

[0018] 1. In solution 1 and its preferred embodiment, a clamping assembly includes a first tube and a clamping member,

[0019] The first tube is provided with a plug-in slot, the plug-in slot is provided with a limiting surface, the limiting surface extends along a first direction and is inclined in a direction away from the center line of the slot opening of the plug-in slot;

[0020] The clamping member is provided with an abutting portion and at least two claw portions protruding from the abutting portion along a first direction, and each claw portion encloses to form a clamping hole, and the clamping hole is used to clamp other parts;

[0021] Each claw portion is suitable for being inserted into the insertion slot along the first direction to cooperate with the limiting surface.

[0022] When each claw portion slides relative to the limiting surface along the second direction, it is suitable to cooperate with the inclined surface of the limiting surface to deform and tighten the clamping hole. Since the limiting surface has a tendency to tilt, as the degree of the inclined surface cooperation deepens, the claw portion deforms more violently, thereby increasing the degree of tightening, reducing the size of the clamping hole, and clamping the part more tightly to prevent it from detaching; when the claw portion slides relative to the limiting surface along the first direction, it restores and opens the clamping hole, thereby increasing the size of the clamping hole and loosening the clamped part, so that the clamping assembly can be adjusted relative to the part along the first direction.

[0023] When adjusting along the second direction, it is only necessary to apply a force along the second direction to the first tube, so that the first tube first moves relative to the claw portion along the second direction, the clamping hole gradually opens, and the first tube abuts against the abutting portion along the second direction, so that each claw portion keeps the clamping hole open. At this time, the force along the second direction is continuously applied to the first tube, and the clamping member and the first tube can synchronously move relative to the component along the second direction.

[0024] When adjusting along the first direction, a force along the first direction is applied to the abutting portion, and the claw portion moves relative to the first tube along the first direction, the clamping hole gradually opens, and when the abutting portion abuts against the first tube along the first direction, each claw portion keeps the clamping hole open. At this time, the force along the first direction continues to be applied to the abutting portion, and the clamping member and the first tube can synchronously move relative to the part along the first direction. Since the clamping force is generated by the deformation of the claw portion, the generated friction force is stronger and is not easily affected by the humid environment. This method does not require the use of a screwdriver and turning a knob, and the adjustment method is relatively simple.

[0025] Moreover, when the first tube is subjected to a force along the first direction, the claw portion cooperates with the inclined surface of the limiting surface, and the clamping hole becomes smaller and smaller, so that the part is clamped, and the clamping piece does not move relative to the part, and the limiting surface of the first tube is limited by the claw portion, resulting in the first tube being unable to move along the first direction.

[0026] 2. In the second scheme and its preferred embodiment, the surface of the clamping hole formed by the clamping claw is provided with a clamping protrusion, thereby increasing the pressure on the parts, making the parts clamped better and preventing them from loosening easily.

[0027] 3. In the third solution and its preferred embodiments, the abutting portion is exposed outside the insertion slot to facilitate the operation of the abutting portion.

[0028] 4. In the fourth solution and its preferred embodiments, a clamping device includes a second tube and the above-mentioned clamping assembly. The second tube is adapted to be inserted into the card hole and has the beneficial effects brought by the above-mentioned clamping assembly.

[0029] 5. In the fifth solution and its preferred embodiments, a dial is further included. The dial is slidably connected to the second tube and is adapted to abut against the abutting portion along the first direction, so as to apply a force to the abutting portion through the dial to adjust the height of the clamping assembly, preventing the situation that it is not easy to adjust by hand due to the too small abutting portion or the small operation space, thereby facilitating the operation.

[0030] 6. In the sixth solution and its preferred embodiments, the second tube includes a connected second outer tube and a second inner tube. The second inner tube is located inside the second outer tube to be protected by the second outer tube. The second inner tube is adapted to be inserted into the card hole and the first tube. The first tube is at least partially located inside the second outer tube, and the clamping member is located inside the second outer tube. The second outer tube is provided with a limiting hole extending along the first direction, and the dial and the limiting hole are adapted to be in limiting cooperation to prevent the second inner tube from disengaging from the clamping assembly and prevent the second inner tube from having too short a mating section with the first tube due to excessive height adjustment, resulting in the first tube shaking insecurely.

[0031] 7. In the seventh solution and its preferred embodiments, the dial includes an operating portion and two relatively spaced clamping portions connected to the operating portion. At least one of the two clamping portions is flexible and is adapted to apply a force to the second inner tube to clamp the second inner tube with the other clamping portion, thereby preventing the dial from falling due to its own gravity, resulting in the dial being too far away from the abutting portion; a part of the operating portion is in limiting cooperation with the limiting hole and a part is exposed outside the second outer tube to facilitate the operation; in the direction perpendicular to the first direction, the size of the clamping portion is larger than the size of the limiting hole, thereby preventing the clamping portion from easily disengaging.

[0032] 8. In the eighth solution and its preferred embodiments, a lock nut and a gasket are further included. The second tube is provided with a sleeve hole. The first tube is adapted to be inserted into the sleeve hole and form a gap with the sleeve hole. The gasket is provided with an inclined surface section. The inclined surface section is adapted to extend into the gap to be clamped by the sleeve hole and the outer wall of the first tube. The lock nut is adapted to be in threaded cooperation with the second tube to abut against the gasket, so that the inclined surface section extends into the gap. As the threaded cooperation between the lock nut and the second tube deepens, the part of the inclined surface section extending into the gap becomes larger, thereby increasing the friction force between the second tube and the first tube and preventing adjustment caused by accidental touch. When it is necessary to adjust the height of the first tube, loosen the lock nut, and the lock nut no longer applies a force to the gasket. At this time, the first tube can take the gasket out of the gap, or the gasket is extruded out of the gap due to the restoration of the second tube and the first tube, thereby reducing the friction force between the first tube and the second tube to allow adjustment.

[0033] 9. In scheme nine and its preferred embodiment, a shower pipe includes the above-mentioned clamping device, and the second pipe is suitable for being inserted into the clamping hole and is sealed and connected with the water path of the first pipe, thereby realizing the connection of the water path and having the beneficial effects brought by the clamping device.

[0034] 10. In scheme 10 and its preferred embodiments, the first tube includes a first section and a second section for passing water in sequence, the first section extends along a first direction and is provided with a plug-in groove, the second section extends along a direction intersecting the first direction and is located on one side of the first section along the first direction, therefore, when water is passing, the second section will be subjected to the back pressure generated by the water flow, exerting a force along the first direction on the second section, and as the upward force increases, the claw portion and the limiting surface gradually cooperate with the inclined surface, the clamping hole becomes smaller and smaller, so that the part is clamped, the clamping part does not move relative to the part, and the limiting surface of the first tube is limited by the claw portion, resulting in the first tube being unable to move in the first direction and not rising, and there is no risk of attenuation of the clamping force after long-term use.

[0052] Reference Figures 1 - 9 , a shower pipe, comprising a clamping device. The clamping device includes a clamping assembly, a second pipe 3, a flap 4, a gasket 5 and a lock nut 6. The clamping assembly includes a first pipe 1 and a clamping member 2.

[0053] Reference Figure 1 , the first pipe 1 includes a first section 11 and a second section 12 through which water passes in sequence. Reference Figure 5 , the first section 11 extends along a first direction 7 and is provided with a socket slot 111. In this embodiment, the first direction 7 is the direction away from the notch of the socket slot 111. The first direction 7 is the direction from bottom to top. The notch of the socket slot 111 faces downward. The limiting surface 1111 extends along the first direction 7 and is inclined in the direction away from the center line of the notch of the socket slot 111. Among them, the limiting surface 1111 can be a curved surface or an inclined surface. In this embodiment, the limiting surface 1111 is a curved surface and is an annular curved surface with a size gradually decreasing along a second direction 8. Among them, the second direction 8 is opposite to the first direction 7 and is the direction from top to bottom. The second section 12 extends along a direction intersecting the first direction 7. In this embodiment, the two are perpendicular to each other. The second section 12 is located above the first section 11 along the first direction 7, that is, the second section 12 is located above the first section 11.

[0054] Specifically, the first pipe 1 includes a first outer pipe 13 and a first inner pipe 14. The first inner pipe 14 is located inside the first outer pipe 13 and is connected into one body by means of a connector or bonding, welding, etc. No more details will be described here. The first outer pipe 13 can be selected from elements with higher strength, while the first inner pipe 14 can be selected from elements with a certain flexibility, such as a PE pipe.

[0055] Reference Figure 5 , Figure 6 , the clamping member 2 is provided with an abutting portion 21 and at least two claw portions 22 protruding along the first direction 7 from the abutting portion 21. Each claw portion 22 encloses to form a clamping hole 23, and the clamping hole 23 is adapted for the second pipe 3 to be inserted. Preferably, the surface of the claw portion 22 enclosing to form the clamping hole 23 is provided with a clamping protrusion 2221 to increase the pressure on the second pipe 3 and make the clamping effect better. Reference Figure 5, each claw portion 22 is suitable for being inserted into the plug-in slot 111 along the first direction 7, and when the claw portion 22 slides relative to the limiting surface 1111 along the second direction 8, it is suitable for cooperating with the inclined surface of the limiting surface 1111 to deform and tighten the clamping hole 23; when the claw portion 22 slides relative to the limiting surface 1111 along the first direction 7, it restores and opens the clamping hole 23, that is, when the claw portion 22 is deformed, it approaches the second tube 3, and when it is restored, it moves away from the second tube 3; specifically, the claw portion 22 includes a connecting portion 221 and a clamping portion 222, and the two ends of the connecting portion 221 are respectively connected to the clamping portion 222 and the abutting portion 21, and the clamping portion 222 is larger than the connecting portion 221. The clamping portion 222 is suitable for cooperating with the inclined surface of the limiting surface 1111. Preferably, the clamping portion 222 is provided with a clamping protrusion 2221, where the deformation amount is the largest, and the clamping protrusion 2221 is arranged here for a better clamping effect. At least one of the slots of the clamping portion 222 and the plug-in slot 111 has an inclined surface, so that the clamping portion 222 is deformed through the cooperation of the inclined surface, so that the clamping portion is deformed and the clamping hole 23 is tightened, thereby allowing entry into the plug-in slot 111 and recovery when crossing the limiting surface 1111, thereby completing the installation of the clamping member 2 on the first tube 1. In the subsequent use process, due to the existence of the second tube 3, the deformation of the clamping member 2 is limited, so it will not detach from the plug-in slot 111.

[0056] The abutment portion 21 is annular, and preferably, the abutment portion 21 is exposed outside the insertion groove 111, and the size of the abutment portion 21 is larger than the size of the opening of the insertion groove 111. The lower surface of the first tube 1 is suitable for abutting against the abutment portion 21 along the second direction 8, or the abutment portion 21 is suitable for abutting against the lower surface of the first tube 1 along the first direction 7, and each claw portion 22 maintains a state of opening the clamping hole 23.

[0057] refer to Figure 4 , Figure 5 The second tube 3 is suitable for being inserted into the clamping hole 23 and is in water-tight communication with the first inner tube 14 of the first tube 1. The sealed communication can be achieved by a corresponding sealing ring.

[0058] Specifically, the second tube 3 includes a second outer tube 31 and a second inner tube 32 connected to each other. The second outer tube 31 is provided with a sleeve hole 311. The sleeve hole 311 is suitable for partially inserting the first tube 1 and forming a gap 9 with the outer wall of the first outer tube 13 of the first tube 1. In this embodiment, the gap 9 is annular. The clamping member 2 is located in the sleeve hole 311 of the second outer tube 31; the second outer tube 31 is provided with a limiting hole 312 extending along the first direction 7, and the limiting hole 312 is connected to the sleeve hole 311.

[0059] The second inner tube 32 is located inside the second outer tube 31 and is connected as a whole by a connector or bonding, welding, etc., which will not be described in detail here. The second inner tube 32 is suitable for being inserted into the clamping hole 23 and is connected to the waterway of the first inner tube 14. A component with higher strength can be selected for the second outer tube 31, while a component with certain flexibility, such as a PE tube, can be selected for the second inner tube 32. Among them, the connector can be the above-mentioned clamping member 2, and the second outer tube 31 can have a corresponding plug-in groove 111, and the notch of the plug-in groove 111 faces upward.

[0060] refer to Figure 4 The gasket 5 is provided with a sloped section 51, which is suitable for extending into the gap 9 to be clamped by the sleeve hole 311 and the outer wall of the first tube 1. In this embodiment, the size of the sloped section 51 along the second direction 8 gradually decreases, and is annular and truncated cone-shaped, so as to adapt to the annular gap 9.

[0061] The lock nut 6 is suitable for threading with the second tube 3 to abut against the gasket 5, and the inclined surface section 51 extends into the gap 9. The greater the extension, the greater the friction force. The second tube 3 and the first tube 1 are not easy to slide.

[0062] refer to Figure 5 , Figure 7 The paddle 4 is slidably connected with the second tube 3 along the first direction 7 and the second direction 8, and is suitable for abutting against the abutting portion 21 along the first direction 7. Specifically, the paddle 4 includes an operating portion 41 and two clamping portions 42 connected to the operating portion 41 and arranged at intervals from each other. The operating portion 41 is generally U-shaped. A portion of the operating portion 41 is suitable for sliding in the limiting hole 312 and is limitedly matched with the limiting hole 312 to prevent the second inner tube 32 from being separated from the clamping assembly. A portion of the operating portion 41 is exposed outside the second outer tube 31 to be suitable for being operated.

[0063] The two clamping parts 42 are roughly arc-shaped to match the shape of the second inner tube 32. At least one of the two clamping parts 42 is flexible to apply force to the second inner tube 32 so as to clamp the second inner tube 32 with the other clamping part 42 to prevent it from falling. Preferably, in this embodiment, both clamping parts 42 are elastic. In the direction perpendicular to the first direction 7, the size of the clamping part 42 is larger than the size of the limiting hole 312 to prevent it from easily escaping from the limiting hole 312. During installation, the clamping part 42 can first enter the sleeve hole 311 from the limiting hole 312 (by turning over the paddle 4 or shrinking the clamping part 42), and then install the second inner tube 32. During the installation of the second inner tube 32, the second inner tube 32 cooperates with the inclined surface of the clamping part 42, so that the clamping part 42 is opened to achieve installation. Since the clamping part 42 is in an open state, it will apply a clamping force to the second inner tube 32, so as to achieve docking and will not fall due to its own gravity.

[0064] During installation, the second inner tube 32 is inserted into the slot of the insertion slot 111, and the second inner tube 32 is abutted against the claw portion 22 to bring the claw portion 22 away from the limiting surface 1111, and the claw portion 22 is stretched open, so that the clamping hole 23 is opened and sleeved on the second inner tube 32. When the second inner tube 32 tends to withdraw from the insertion slot 111, the claw portion 22 is driven to cooperate with the limiting surface 1111, and the claw portion 22 is squeezed, so that the clamping hole 23 better holds the second inner tube 32 to prevent the second inner tube 32 from falling out.

[0065] During use, when the height of the first tube 1 needs to be adjusted, the lock nut 6 is first unscrewed to disengage the lock nut 6 from the gasket 5 to allow the first tube 1 to move relative to the second tube 3 .

[0066] Adjust the height upward: push the paddle 4 upward, the paddle 4 acts on the abutting portion 21 of the clamping member 2, so that the clamping member 2 moves relative to the first tube 1 along the first direction 7, and the claw portion 22 of the clamping member 2 gradually disengages from the inclined surface 1111, the claw portion 22 recovers and opens the clamping hole 23, so that the clamping member 2 can move relative to the second tube 3 along the first direction 7. At the same time, in this process, the abutting portion 21 will abut against the first tube 1 along the first direction 7, so that in this case the paddle 4 can drive the clamping member 2 and the first tube 1 to move upward together, until the operating portion 41 of the paddle 4 abuts against the upper end hole wall of the limiting hole 312 and cannot move further upward.

[0067] Adjust the height downward: apply a force along the second direction 8 to the first tube 1, the first tube 1 moves along the second direction 8 relative to the clamping member 2, the limiting surface 1111 and the claw portion 22 of the clamping member 2 gradually disengage from the inclined surface cooperation, the claw portion 22 recovers and opens the clamping hole 23, so that the clamping member 2 can move along the second direction 8 relative to the second tube 3. At the same time, in this process, the first tube 1 will abut against the abutting portion 21 along the second direction 8, and the abutting portion 21 will abut against the paddle 4 along the second direction 8, so that in this case the first tube 1 can drive the clamping member 2 and the paddle 4 to move downward together until the operating portion 41 of the paddle 4 abuts against the lower end hole wall of the limiting hole 312 and cannot move further downward.

[0068] When the height adjustment is completed, the lock nut 6 is tightened to insert the gasket 5 into the gap 9 between the first tube 1 and the second tube 3 to increase the friction between the two, thereby preventing sliding caused by accidental touch.

[0069] Compared with the prior art, this embodiment has the following beneficial effects:

[0070] In an exemplary embodiment, a clamping assembly includes a first tube 1 and a clamping member 2.

[0071] The first tube 1 is provided with an inserting groove 111, and the inserting groove 111 is provided with a limiting surface 1111, the limiting surface 1111 extends along the first direction 7 and is inclined in a direction away from the center line of the notch of the inserting groove 111;

[0072] The clamping member 2 is provided with an abutting portion 21 and at least two claw portions 22 protruding from the abutting portion 21 along the first direction 7. Each claw portion 22 encloses to form a clamping hole 23 for clamping other parts.

[0073] Each claw portion 22 is adapted to be inserted into the insertion slot 111 along the first direction 7 to cooperate with the limiting surface 1111.

[0074] When each claw portion 22 slides relative to the limiting surface 1111 along the second direction 8, it is adapted to cooperate with the inclined surface of the limiting surface 1111 to deform and tighten the clamping hole 23. Since the limiting surface 1111 has an inclined tendency, therefore, as the degree of the inclined surface cooperation deepens, the deformation of the claw portion 22 becomes more intense, so the tightening degree is greater, the size of the clamping hole 23 is smaller, and the part is clamped more tightly to prevent detachment. When the claw portion 22 slides relative to the limiting surface 1111 along the first direction 7, it restores and expands the clamping hole 23, so that the size of the clamping hole 23 becomes larger, and the clamped part is loosened, so that the clamping assembly can be adjusted relative to the part along the first direction 7.

[0075] When adjusting along the second direction 8, only need to apply a force along the second direction 8 to the first pipe 1, then the first pipe 1 first moves relative to the claw portion 22 along the second direction 8, the clamping hole 23 gradually expands, and when the first pipe 1 abuts against the abutting portion 21 along the second direction 8, each claw portion 22 is kept in a state of expanding the clamping hole 23. At this time, when continuing to apply a force along the second direction 8 to the first pipe 1, the clamping member 2 and the first pipe 1 can move synchronously relative to the part along the second direction 8.

[0076] When adjusting along the first direction 7, apply a force along the first direction 7 to the abutting portion 21, then the claw portion 22 moves relative to the first pipe 1 along the first direction 7, the clamping hole 23 gradually expands, and when the abutting portion 21 abuts against the first pipe 1 along the first direction 7, each claw portion 22 is kept in a state of expanding the clamping hole 23. At this time, when continuing to apply a force along the first direction 7 to the abutting portion 21, the clamping member 2 and the first pipe 1 can move synchronously relative to the part along the first direction 7, and because the clamping force is generated by the deformation of the claw portion 22, the generated frictional force is stronger and is not easily affected by the humid environment. This method does not require a screwdriver and a rotating knob, and the adjustment method is relatively simple.

[0077] Moreover, when the first pipe 1 is subjected to a force along the first direction 7, the claw portion 22 cooperates with the inclined surface of the limiting surface 1111, and the clamping hole 23 becomes smaller and smaller, so that the part is tightly held, the clamping member 2 does not move relative to the part, and the limiting surface 1111 of the first pipe 1 is limited by the claw portion 22, resulting in that the first pipe 1 cannot move along the first direction 7.

[0078] In an exemplary embodiment, the surface of the jaw portion 22 that encloses to form the clamping hole 23 is provided with a clamping protrusion 2221, thereby increasing the pressure on the part, making the clamping effect of the part better and preventing it from loosening easily.

[0079] In an exemplary embodiment, the abutting portion 21 is exposed outside the insertion slot 111 to facilitate the operation of the abutting portion 21.

[0080] In an exemplary embodiment, a clamping device includes a second tube 3 and the above-mentioned clamping assembly. The second tube 3 is adapted to be inserted into the clamping hole 23 and has the beneficial effects brought by the above-mentioned clamping assembly.

[0081] In an exemplary embodiment, a dial 4 is further included. The dial 4 is slidably connected to the second tube 3 and is adapted to abut against the abutting portion 21 along the first direction 7, so as to apply a force to the abutting portion 21 through the dial 4 to adjust the height of the clamping assembly, preventing the situation that it is not easy to adjust by hand due to the too small abutting portion 21 or the small operation space, thereby facilitating the operation.

[0082] In an exemplary embodiment, the second tube 3 includes a connected second outer tube 31 and a second inner tube 32. The second inner tube 32 is located inside the second outer tube 31 to be protected by the second outer tube 31. The second inner tube 32 is adapted to be inserted into the clamping hole 23 and the first tube 1. At least part of the first tube 1 is located inside the second outer tube 31, and the clamping member 2 is located inside the second outer tube 31; a limiting hole 312 extending along the first direction 7 is provided on the second outer tube 31. The dial 4 and the limiting hole 312 are adapted to be in limiting cooperation to prevent the second inner tube 32 from detaching from the clamping assembly and prevent the cooperation section between the second inner tube 32 and the first tube 1 from being too short due to excessive height adjustment, resulting in unsafe shaking of the first tube 1.

[0083] In an exemplary embodiment, the dial 4 includes an operating portion 41 and two relatively spaced clamping portions 42 connected to the operating portion 41. At least one of the two clamping portions 42 is flexible and is adapted to apply a force to the second inner tube 32 to clamp the second inner tube 32 with the other clamping portion 42, thereby preventing the dial 4 from falling due to its own gravity, resulting in the dial 4 being too far away from the abutting portion 21; a part of the operating portion 41 is in limiting cooperation with the limiting hole 312 and a part is exposed outside the second outer tube 31 to facilitate the operation; in the direction perpendicular to the first direction 7, the size of the clamping portion 42 is larger than the size of the limiting hole 312, thereby preventing the clamping portion 42 from detaching easily.

[0084] In an exemplary embodiment, a lock nut 6 and a gasket 5 are further included. The second pipe 3 is provided with a socket hole 311. The first pipe 1 is adapted to be inserted into the socket hole 311 and a gap 9 is formed between the first pipe 1 and the socket hole 311. The gasket 5 is provided with an inclined surface section 51. The inclined surface section 51 is adapted to extend into the gap 9 and be clamped between the outer wall of the socket hole 311 and the first pipe 1. The lock nut 6 is adapted to be threadedly engaged with the second pipe 3 and press against the gasket 5, so that the inclined surface section 51 extends into the gap 9. As the threaded engagement between the lock nut 6 and the second pipe 3 deepens, the portion of the inclined surface section 51 extending into the gap 9 becomes larger, thereby increasing the frictional force between the second pipe 3 and the first pipe 1 and preventing adjustment caused by accidental touch. When the height of the first pipe 1 needs to be adjusted, the lock nut 6 is loosened, and the lock nut 6 no longer exerts a force on the gasket 5. At this time, the first pipe 1 can take the gasket 5 out of the gap 9, or the gasket 5 is extruded out of the gap 9 due to the restoration of the second pipe 3 and the first pipe 1 (the deformation of the second pipe 3 and / or the first pipe 1 occurs when the inclined surface section 51 enters the gap 9), thereby reducing the frictional force between the first pipe 1 and the second pipe 3 to allow adjustment.

[0085] In an exemplary embodiment, a shower pipe includes the above clamping device. The second pipe 3 is adapted to be inserted into the clamping hole 23 and is in sealed communication with the water passage of the first pipe 1, thereby realizing the connection of the water passage and having the beneficial effects brought by the clamping device.

[0086] In an exemplary embodiment, the first pipe 1 includes a first section 11 and a second section 12 that pass water in sequence. The first section 11 extends along the first direction 7 and is provided with a socket slot 111. The second section 12 extends along a direction intersecting the first direction 7 and is located on one side of the first section 11 along the first direction 7. Therefore, when water is flowing, the second section 12 will be subjected to the back pressure generated by the water flow, and a force along the first direction 7 is applied to the second section 12. As the upward force becomes larger, the claw portion 22 and the limiting surface 1111 are gradually in inclined surface cooperation, and the clamping hole 23 becomes smaller and smaller, so that the part is tightly held. The clamping member 2 does not move relative to the part, and the limiting surface 1111 of the first pipe 1 is limited by the claw portion 22, resulting in that the first pipe 1 cannot move along the first direction 7 and will not move upward. There is no risk of attenuation of the clamping force during long-term use.
