Description

Technical Field

[0001] This application relates to the field of bathroom technology, and in particular to a telescopic rod and spray device for showering. Background Technology

[0002] Currently, to adjust a shower head to the required height during installation, water pipes of appropriate length must be pre-cut at the manufacturing plant based on the homeowner's height needs and then brought to the construction site for on-site installation. However, various problems may arise during actual on-site installation, such as the failure to consider environmental limitations during the initial measurement, resulting in a discrepancy between the required water pipe length and the pre-cut pipe.

[0003] Regarding the aforementioned technologies, existing shower heads have a problem where the pre-cut water pipe length does not match the expected length during installation, requiring the appropriate length of water pipe to be cut from the factory and adapted, which is quite troublesome. Summary of the Invention

[0004] To address the issue that during shower head installation, the pre-cut water pipe length may not match the expected length, necessitating the re-cutting of the appropriate water pipe length from the factory and subsequent adaptation, this application provides a shower telescopic rod.

[0005] Firstly, this application provides a telescopic rod for showering, employing the following technical solution:

[0006] A shower telescopic rod includes a first pipe and a second pipe, the second pipe being inserted into the first pipe. It also includes a mounting sleeve for connecting the first and second pipes. The end of the first pipe for inserting into the second pipe is provided with a toothed claw. Each toothed claw includes claw strips connected to the first pipe, the claw strips being spaced apart circumferentially along the first pipe, with a gap formed between adjacent claw strips. The inner hole of the mounting sleeve has an annular inclined surface, and each claw strip has an inclined surface corresponding to the annular inclined surface. The annular inclined surface and the inclined surface abut against each other to gather the claw strips with the inclined surfaces. The mounting sleeve is fitted and fixed onto the first pipe and gathers and tightens the claw strips with the toothed claws. A second pipe fitting is inserted into a first pipe fitting; the mounting sleeve has a through hole, through which the first pipe fitting passes and is connected to the mounting sleeve; one end of the mounting sleeve is threaded to the first pipe fitting, and the other end of the mounting sleeve is provided with a retaining tooth; the second pipe fitting has an annular groove, and the retaining tooth and the annular groove form an elastic snap-fit ​​when the second pipe fitting is inserted into the first pipe fitting; the mounting sleeve is provided with a locking mechanism, which includes a sliding member slidably disposed within the mounting sleeve, the sliding member moving in a direction perpendicular to the claw bar and passing through the mounting sleeve to abut against the claw bar of the toothed claw; the mounting sleeve is also provided with a spring retaining ball for restricting the movement of the sliding member, the spring retaining ball being used to restrict the movement of the sliding member when the sliding member abuts against the claw bar.

[0007] By adopting the above technical solution, the second pipe fitting is inserted into the first pipe fitting, and then the mounting sleeve is fitted and fixed onto the first pipe fitting. Simultaneously, the mounting sleeve is fixed onto the first pipe fitting, and the toothed claw strips on the first pipe fitting are compressed and tightened by the annular inclined surface. This causes the toothed claw strips to tightly grip and fix the second pipe fitting, thereby achieving a connection and fixation between the first pipe fitting, the second pipe fitting, and the mounting sleeve. This also satisfies the need to adjust the telescopic length of the first and second pipe fittings, while improving the stability of the connection between the first and second pipe fittings and solving the problem of pipe fittings easily slipping off. When the second pipe fitting is inserted into the first pipe fitting, and the mounting sleeve locks the first and second pipe fittings, the retaining teeth on the mounting sleeve and the annular groove on the second pipe fitting form an elastic locking engagement, improving the connection stability between the second pipe fitting and the mounting sleeve, and thus improving the overall stability of the telescopic rod. The sliding member in the drive mounting sleeve moves toward the toothed claw until it abuts against the claw strip of the toothed claw. At this time, the spring retainer engages with the sliding member to restrict its movement. That is, by having the sliding member abut against the claw strip of the toothed claw, the clamping force of the mounting sleeve on the first pipe is increased, thereby improving the stability of the connection between the mounting sleeve and the first pipe.

[0008] Preferably, the mounting sleeve has a sliding hole, the sliding member is slidably disposed in the sliding hole, and the sliding hole is provided with a first elastic member for driving the sliding member to move away from the toothed claw. The first elastic member drives the sliding member to reset to the initial state after being unlocked.

[0009] By adopting the above technical solution, after the sliding member is driven to move so that it is released from the locking of the spring ball, the sliding member can be reset to the initial state under the action of the first elastic member, which has good self-driving reset performance.

[0010] Preferably, the mounting sleeve is provided with a triggering device for locking the sliding member; a sliding hole is provided in the mounting sleeve, the sliding member is slidably disposed in the sliding hole, and a second elastic member is provided in the sliding hole for driving the sliding member to move toward the toothed claw. After the triggering device releases the locking of the sliding member, the second elastic member drives the sliding member to abut against the claw strip and makes the sliding member and the spring retaining ball form a locking engagement.

[0011] By adopting the above technical solution, after the triggering device releases the lock on the sliding member, the second elastic member can drive the sliding member in the mounting sleeve to move toward the toothed claw until the sliding member abuts against the claw strip of the toothed claw. At this time, the spring retaining ball is engaged with the sliding member to restrict the movement of the sliding member, which has good self-driving abutment performance.

[0012] Preferably, the triggering device includes a locking pin, and the sliding member is provided with a pull ring; when the spring retaining ball releases the restriction on the sliding member, and the sliding member resets against the action of the second elastic member, the pull ring extends out of the mounting sleeve through the sliding hole, and the locking pin is inserted into the pull ring and abuts against the mounting sleeve under the action of the second elastic member.

[0013] By adopting the above technical solution, the sliding member is driven to move in the reverse direction to overcome the force of the second elastic member until the pull ring extends out of the mounting sleeve through the sliding hole. At this time, the locking pin can be inserted into the pull ring and abut against the mounting sleeve to restrict the second elastic member from driving the sliding member to move.

[0014] Preferably, the toothed claw has a thin-walled abutment groove formed on its claw strip, and the sliding member is provided with an abutment member. The shape of the abutment member is adapted to the shape of the claw strip, and the abutment member passes through the mounting sleeve and abuts against the abutment groove under the action of the sliding member.

[0015] By adopting the above technical solution, a thin-walled abutment groove is opened on the claw bar of the toothed claw, and the abutment member on the sliding member can be adapted to abut in the abutment groove. By the deformation of the claw bar at the abutment groove, the force of the toothed claw to tighten the second pipe is increased, thereby improving the stability of the connection between the first pipe and the second pipe.

[0016] Preferably, the sliding member has a snap-fit ​​recess, the snap-fit ​​recess includes a recessed bottom surface, and a planar recessed surface is formed on the periphery of the recessed bottom surface. The planar recessed surface is inclined along the sliding direction of the sliding member and forms a snap-fit ​​engagement with the spring retaining ball when the spring retaining ball slides into the snap-fit ​​recess.

[0017] By adopting the above technical solution, when the spring ball slides into the locking recess of the slider, the planar recess of the locking recess and the spring ball form a locking engagement, thereby increasing the magnitude of the force by which the spring ball and the slider release the locking, and improving the stability of the slider against the toothed claw.

[0018] Preferably, the mounting sleeve is made of an elastic deformable material, and the diameter of the first pipe is larger than the inner diameter of the mounting sleeve. The first pipe expands one end of the mounting sleeve by pressing outward, while the other end of the mounting sleeve converges and tightens the toothed claws inward.

[0019] By adopting the above technical solution, when the mounting sleeve is fixed on the first pipe fitting, the first pipe fitting squeezes and expands one end of the mounting sleeve outward, while the other end of the mounting sleeve gathers and tightens the toothed claws inward, further increasing the magnitude of the tightening force.

[0020] Preferably, the first pipe fitting is provided with an installation limiting structure, the limiting structure including an installation cylinder coaxially embedded in the first pipe fitting, the installation cylinder and the second pipe fitting inserted into the first pipe fitting forming an interference fit.

[0021] By adopting the above technical solution, the interference fit between the mounting sleeve and the second pipe fitting improves the connection stability of the part of the second pipe fitting inserted into the first pipe fitting, limits the possible displacement or swaying of the second pipe fitting, and further improves the stability of the connection between the first pipe fitting and the second pipe fitting.

[0022] Preferably, the inner wall of the mounting cylinder is provided with an elastic plastic cylinder, which extends toward the first pipe fitting to form an elastic protrusion. The elastic protrusion and the annular groove on the second pipe fitting inserted into the first pipe fitting form an elastic snap-fit ​​engagement.

[0023] By adopting the above technical solution, the elastic protrusion and the annular groove form an elastic snap-fit, realizing a stable connection between the insertion parts of the first and second pipe fittings, while not affecting the normal insertion action of the second pipe fitting.

[0024] Secondly, this application provides a shower device, which adopts the following technical solution:

[0025] A shower device includes the aforementioned shower telescopic rod. The end of the first pipe fitting, located away from the mounting sleeve where it connects to the two pipe fittings, is provided with a mounting base. The end of the second pipe fitting, located away from the mounting sleeve where it connects to the two pipe fittings, is provided with a pipe connector. The pipe connector includes a connecting head, which is connected to an inlet connector and an outlet connector. The connecting head is also provided with a fixing connector, which is snapped and fixed to the end of the second pipe fitting.

[0026] By adopting the above technical solution, the mounting base is used to fix the telescopic rod, while the pipe joint is used to realize the flow of shower water, and the connection and fixing method between the pipe joint and the second pipe fitting is relatively convenient. On this basis, it can meet the needs of shower water pipe penetration operation and the needs of direct water flow construction operation for sprinkler water, while having good sealing performance and connection stability.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By installing and fixing the mounting sleeve on the first pipe fitting, the toothed claws on the first pipe fitting are gathered together. The toothed claws deform and gather to hug the second pipe fitting, thereby realizing the connection and fixation of the first pipe fitting, the second pipe fitting and the mounting sleeve, and meeting the needs of adjusting the extension length of the first pipe fitting and the second pipe fitting. At the same time, it helps to improve the stability of the connection between the first pipe fitting and the second pipe fitting, and solves the problem that the pipe fitting is prone to slipping.

[0029] 2. By arranging a locking mechanism on the mounting sleeve and optimizing the structure of the mounting sleeve, snap-fit ​​recess, and claw strip, the stability of the connection between the first pipe fitting, the second pipe fitting, and the mounting sleeve is improved, thus solving the problem of the mounting sleeve slipping off due to vibration during the use of the shower telescopic rod.

[0030] 3. Install mounting bases and pipe joints on the telescopic rod to achieve the functions of installation and water flow in the shower. Attached Figure Description

Detailed Implementation

[0050] The following is in conjunction with the appendix Figure 1-18 This application will be described in further detail.

[0051] This application discloses a telescopic rod for showering.

[0052] Example 1

[0053] Reference Figure 1 As shown, a shower telescopic rod includes a first pipe 1 and a second pipe 2, which are connected by a plug-in joint. An installation sleeve 3 is detachably connected at the plug-in position of the first pipe 1 and the second pipe 2. The installation sleeve 3 is fitted over the first pipe 1 and the second pipe 2 and fixes the first pipe 1 and the second pipe 2.

[0054] Combination Figure 1 and Figure 2As shown in the embodiment of this application, both the first pipe fitting 1 and the second pipe fitting 2 are hollow straight pipes, and the first pipe fitting 1 and the second pipe fitting 2 form a coaxial insertion fit. A through hole 31 is formed along a straight line on the mounting sleeve 3. One end of the second pipe fitting 2 is coaxially inserted into the first pipe fitting 1, and the mounting sleeve 3 is fitted onto the first pipe fitting 1 to lock the first pipe fitting 1 and the second pipe fitting 2. Of course, the shape of the first pipe fitting 1 and the second pipe fitting 2 does not necessarily have to be a straight pipe; for example, there may be a bent portion in the pipe. As long as the mounting sleeve 3 can be fitted at the joint position of the first pipe fitting 1 and the second pipe fitting 2, it is acceptable.

[0055] Combination Figure 2 and Figure 3 As shown, the end of the first pipe fitting 1 used for inserting the second pipe fitting 2 has a deformable toothed claw 11. In this embodiment, the end of the first pipe fitting 1 is cut multiple times along the axial direction of the pipe fitting to form a claw strip 111 and a spaced-apart hole 112 structure along the circumferential direction at the end of the first pipe fitting 1; this structure is the toothed claw 11. Figure 2 and Figure 3 As shown, a threaded section 12 is formed on the body of the first pipe fitting 1 near the toothed claw 11, or, combined with Figure 4 and Figure 5 As shown, the threaded section 12 is directly formed on the claw bar 111 near the pipe body of the first pipe fitting 1. Combined with... Figure 3 and Figure 5 As shown, the mounting sleeve 3 and the threaded section 12 form a threaded engagement. During the process of tightening the mounting sleeve 3 onto the threaded section 12, the wall of the through hole 31 squeezes the claw strip 111, so that the claw strip 111 gathers inward and fits against the tube body of the second tube 2, thereby achieving the purpose of the toothed claw 11 clamping and fixing the second tube 2, and thus achieving the purpose of connecting and fixing the first tube 1 and the second tube 2.

[0056] Combination Figure 3 and Figure 5 As shown, in addition to the threaded surface 32 formed on the wall of the through hole 31 of the mounting sleeve 3 for threaded connection with the threaded section 12, an annular inclined surface 33 is also formed. This annular inclined surface 33 is used to compress and wrap the claw strip 111. (Refer to...) Figure 3 As shown, when the mounting sleeve 3 is threadedly connected to the pipe body of the first pipe fitting 1, the annular inclined surface 33 is not completely formed on the hole wall of the through hole 31. That is, the annular inclined surface 33 extends from the position of the opening near one side of the through hole 31 to the middle position of the through hole 31, while the threaded surface 32 extends from the middle position of the through hole 31 to the opening on the other side of the through hole 31. This satisfies both the stability requirements of the threaded fit and the tightness requirements of the compression and wrapping of the claw strip 111. (Refer to...) Figure 5As shown, when the mounting sleeve 3 is threadedly connected to the claw bar 111, although the annular inclined surface 33 is not completely formed on the wall of the through hole 31, the annular inclined surface 33 extends from the position of the opening on the side near the through hole 31 to a position close to one-third of the height of the through hole 31, while the threaded surface 32 continues to extend upward from the one-third position for a short distance. That is, in the second case, the mating length between the threaded surface 32 and the claw bar 111 is less than the mating length between the threaded surface 32 and the claw bar 111 in the first case.

[0057] Correspondingly, combined Figure 3 and Figure 5 As shown, the toothed claw 11 has an inclined surface 113 formed on its claw strip 111 for forming an inclined surface compression fit with the annular inclined surface 33. This inclined surface 113 is the outer wall of the claw strip 111, and the inner wall of the claw strip 111 is used to compress and wrap the tube body of the second tube 2. The inclined surface 113 also has two types of opening and extension methods, combined with... Figure 3 and Figure 6 As shown, the first type is completely formed on the outer wall of the claw strip 111, that is, extending from the free end 1111 of the claw strip 111 away from the first tube 1 to the fixed end 1112 where the claw strip 111 connects to the first tube 1; see reference. Figure 5 As shown, the second type is not fully formed on the outer wall of the claw strip 111, that is, it extends from the free end 1111 of the claw strip 111 away from the first tube 1 to the threaded section 12 on the outer wall of the claw strip 111.

[0058] Reference Figure 6 As shown, in this embodiment, the thickness of the inclined surface 113 on the claw bar 111 gradually increases along the direction from the free end 1111 to the fixed end 1112. Combined with... Figure 3 and Figure 6 As shown or in combination Figure 5 and Figure 6 As shown, the through hole 31 of the mounting sleeve 3, corresponding to the free end 1111 of the claw bar 111, is named the distal end 311, while the through hole 31 of the mounting sleeve 3, corresponding to the fixed end 1112 of the claw bar 111, is named the proximal end 312. The annular inclined surface 33 at the distal end 311 of the through hole 31 slopes towards the claw bar 111, while the annular inclined surface 33 at the proximal end 312 of the through hole 31 slopes away from the claw bar 111. The annular inclined surface 33 smoothly transitions from the distal end 311 to the proximal end 312. When the mounting sleeve 3 is tightened, the distal end 311 of the through hole 31 of the mounting sleeve 3 can better converge the free end 1111 of the claw bar 111, improving the convergence effect of the mounting sleeve 3 on the free end 1111 of the claw bar 111.

[0059] The number of claw strips 111 and spacer holes 112 formed by cutting can be determined according to the hardness of the material of the first tube 1 and the size of the contact area between the toothed claws 111 and the second tube 2. If the material of the first tube 1 is relatively hard, the number of claw strips 111 and spacer holes 112 can be appropriately increased and the spacing of the spacer holes 112 can be reduced; conversely, the number of claw strips 111 and spacer holes 112 can be appropriately reduced and the spacing of the spacer holes 112 can be increased. If a larger squeezing and wrapping force is required, the inner wall area of ​​the claw strips 111 of the toothed claws 11 in contact with the second tube 2 can be increased to improve the locking effect; conversely, the inner wall area of ​​the claw strips 111 of the toothed claws 11 in contact with the second tube 2 can be reduced.

[0060] Of course, the claw strip 111 can also be directly fixed to the original first pipe fitting 1 by welding, bonding, snap-fitting, fusion welding, etc., and then the claw strip 111 forms the toothed claw 11. Keeping the inner wall of the fixed claw strip 111 coplanar with the inner wall of the original first pipe fitting 1 is beneficial to improving the smoothness of the insertion and mating of the first pipe fitting 1 and the second pipe fitting 2; if the inner wall of the fixed claw strip 111 is not coplanar with the inner wall of the original first pipe fitting 1 or the inner wall has unevenness, as long as it does not affect the second pipe fitting 2 from passing through the first pipe fitting 1, the above fixing methods can be selected.

[0061] Combination Figure 3 and Figure 5 As shown, to further improve the stability of the connection between the first pipe fitting 1 and the second pipe fitting 2, a retaining tooth 34 is formed on the mounting sleeve 3. Correspondingly, an annular groove 21 is formed on the body of the second pipe fitting 2. Through the elastic engagement of the retaining tooth 34 and the annular groove 21, the mounting sleeve 3 and the second pipe fitting 2 are locked together. In this embodiment, the retaining tooth 34 is located on the wall of the through hole 31 away from the opening of the first pipe fitting 1. The retaining tooth 34 is arranged circumferentially along the mounting sleeve 3, and several sets of retaining teeth 34 are arranged at intervals along the axial direction of the mounting sleeve 3. Similarly, the annular groove 21 is opened circumferentially along the second pipe fitting 2 and several sets are opened at intervals along the axial direction of the second pipe fitting 2. The spacing of the annular groove 21 is the same as the spacing of the retaining tooth 34. Therefore, during the tightening of the mounting sleeve 3, the retaining tooth 34 can engage with the annular groove 21. Since the retaining tooth 34 itself has a certain elastic deformation capability, it will not affect the tightening or loosening of the mounting sleeve 3.

[0062] Reference Figure 1 As shown, during the assembly of the first pipe fitting 1 and the second pipe fitting 2, in order to restrict the mounting sleeve 3 from rotating freely or even slipping off, three sets of limiting protrusions 13 are formed on the pipe body of the first pipe fitting 1 near the bottom. The first set of limiting protrusions 13 at the bottom engages with the top opening of the mounting sleeve 3 to prevent rotation, while the second set of limiting protrusions 13 in the middle and the third set of limiting protrusions 13 at the top work together to prevent slippage.

[0063] The implementation principle of Example 1 is as follows: the toothed claws 11 on the first pipe fitting 1 are gathered and fixed by the toothed claws 11. On this basis, the connection stability between the first pipe fitting 1 and the second pipe fitting 2 is further improved by the snap-fit ​​fixing of the mounting sleeve 3 and the second pipe fitting 2, so as to realize the overall connection and fixation of the first pipe fitting 1, the second pipe fitting 2 and the mounting sleeve 3.

[0064] Example 2

[0065] Reference Figure 7 As shown, a shower telescopic rod differs from Embodiment 1 in that the structure of the mounting sleeve 3 is different. In this embodiment, the mounting sleeve 3 is provided with a locking mechanism 4; after the mounting sleeve 3 is tightened onto the first pipe fitting 1, the user can further lock the first pipe fitting 1 and the second pipe fitting 2 through the locking mechanism 4.

[0066] Reference Figure 7 As shown, the locking mechanism 4 includes a sliding member 41 that slides through the mounting sleeve 3. The sliding member 41 slides in a direction perpendicular to the axial direction of the first tube 1. A driving member 42 is installed at the end of the sliding member 41 away from the first tube 1, while an abutment member 43 is installed at the other end of the sliding member 41 close to the first tube 1. A spring retaining ball 44 is also provided inside the mounting sleeve 3 to restrict the movement of the sliding member 41. Figure 7 and Figure 8 As shown, after the mounting sleeve 3 is tightened, the user drives the sliding member 41 to move by pressing the driving member 42. The sliding member 41 slides towards the toothed claw 11, causing the abutment member 43 to press against the first tube 1. At this time, the spring retaining ball 44 and the sliding member 41 form a locking engagement to restrict the movement of the moving part, thereby achieving the purpose of locking the first tube 1 and the second tube 2. When it is necessary to unlock, the user pulls the driving member 42 in the opposite direction, so that the sliding member 41 overcomes the restriction of the spring retaining ball 44 and moves in the opposite direction to reset.

[0067] Specifically, combined Figure 7 and Figure 8As shown, a sliding hole 35 is formed through the mounting sleeve 3 in a direction perpendicular to the axial direction of the first pipe 1. The sliding hole 35 forms a first opening 351 on the outer wall of the mounting sleeve 3 and a second opening 352 on the inner wall of the mounting sleeve 3. The sliding member 41 and the sliding hole 35 form a sliding fit. In this embodiment, a smooth rod is used as the sliding member 41, and a block structure is fixed at one end of the rod structure, and an arc-shaped plate is fixed at the other end. The block structure serves as the driving member 42, and the arc-shaped plate serves as the abutment member 43. The user presses the driving member 42 through the first opening 351, and the driving member 42 drives the sliding member 41 to move in the sliding hole 35 until the spring retaining ball 44 and the sliding member 41 form a snap-fit ​​fit. At the same time, the abutment member 43 passes through the second opening 352 through the sliding hole 35 and abuts against the first pipe 1.

[0068] Combination Figure 7 and Figure 8 As shown, the sliding hole 35 is a multi-segment irregular opening structure, including three parts: the first segment 353, the middle segment 354, and the tail segment 355. The middle segment 354 is a cylindrical hole opened in the mounting sleeve 3. The diameter of the middle segment 354 is larger than the rod diameter of the sliding member 41. The spring retaining ball 44 is also arranged in the mounting sleeve 3 at the position corresponding to the cylindrical hole. The tail segment 355 is also a cylindrical hole. The first opening 351 is the opening of the tail segment 355, but the diameter of the tail segment 355 is smaller than the rod diameter of the sliding member 41. Correspondingly, the driving member 42 is a cylindrical block structure. The driving member 42 can be integrally formed with the sliding member 41, or it can be coaxially fixed to the sliding member 41 by a detachable connection method such as a threaded connection. The first segment 353 is a groove structure whose shape is adapted to the abutment member 43. The second opening 352 is the opening of the first segment 353.

[0069] In addition, combined Figure 7 and Figure 8As shown, a first elastic element 45 is arranged inside the sliding hole 35. In this embodiment, a spring is used as the first elastic element 45. One end of the spring is bonded and fixed to the inner wall of the sliding hole 35, and the other end of the spring is bonded and fixed to the outer wall of the rod of the sliding member 41. The first elastic element 45 is compressed between the tail section 355 and the spring retainer 44, providing the sliding member 41 with a driving force to slide towards the tail section 355. When the locking mechanism 4 is in the unlocked state, the driving member 42 is inserted into the tail section 355 under the action of the first elastic element 45 and exposed outside through the first opening 351. The end of the sliding member 41 near the tail section 355 abuts against the end wall of the middle section 354. At this time, the spring retainer 44 does not form a snap-fit ​​with the sliding member 41, and the front end of the abutment member 43 is inserted into the first section 353. When the locking mechanism 4 is in the locked state, the spring ball 44 and the sliding member 41 form a snap-fit ​​engagement, the abutment member 43 is inserted into the first section 353 and continues to extend outward through the second opening 352 until it abuts against the first tube 1, and at this time the driving member 42 retracts into the tail section 355 through the first opening 351.

[0070] Combination Figure 7 and Figure 8 As shown, in order to facilitate the user to pull the slider 41 outward toward the mounting sleeve 3 to release the locking state of the locking mechanism 4, a locking ring 421 can be locked on the outer wall of the drive member 42. The user can release the lock of the spring bead 44 on the slider 41 by pulling the ring 421. After the spring bead 44 is released from the restriction on the slider 41, the slider 41 can be reset to the initial state under the action of the first elastic member 45.

[0071] Combination Figure 7 and Figure 9 As shown, a snap-fit ​​hole 36 is formed inside the mounting sleeve 3 along a direction perpendicular to the middle section 354 of the sliding hole 35. The snap-fit ​​hole 36 is arranged circumferentially along the sliding hole 35, and the aforementioned spring retaining beads 44 are arranged inside the snap-fit ​​hole 36. The specific number of snap-fit ​​holes 36 can be determined according to the magnitude of the limiting force of the spring retaining beads 44 on the sliding member 41. The more snap-fit ​​holes 36 there are, the more spring retaining beads 44 can be arranged, and the greater the limiting force of the spring retaining beads 44 on the sliding member 41, and the greater the force required for the user to unlock. One end of the snap-fit ​​hole 36 penetrates the mounting sleeve 3 in the direction of the outside of the mounting sleeve 3 and forms a third opening 361 on the outer wall of the mounting sleeve 3. The other end of the snap-fit ​​hole 36 penetrates the sliding hole 35 in the direction of the inside of the mounting sleeve 3 and forms a fourth opening 362 for connecting the sliding hole 35. Lock the closure 37 onto the mounting sleeve 3. The closure 37 is used to block the third opening 361 to facilitate the installation of the spring retainer 44, while the fourth opening 362 is used to allow the spring retainer 44 to extend into the middle section 354 of the sliding hole 35 to engage the sliding member 41.

[0072] Combination Figure 7 and Figure 9 As shown, the spring retaining ball 44 includes a third elastic element 441 and a retaining connector 442. In this embodiment, a spring is used as the third elastic element 441. One end of the spring is bonded and fixed to the closing member 37 at the third opening 361, and the other end of the spring is bonded and fixed to the retaining connector 442. The retaining connector 442 includes a retaining plate 4421. One side of the retaining plate 4421 is used to bond and fix the spring, while the other side of the retaining plate 4421 is integrally formed or detachably installed with a retaining ball 4422. The shape and size of the fourth opening 362 are adapted to the retaining ball 4422, allowing only the retaining ball 4422 to pass through. The retaining plate 4421 is engaged at the fourth opening 362 of the retaining hole 36. Correspondingly, a retaining recess 7 is formed on the rod of the sliding member 41. The retaining recess 7 is a groove structure, and the retaining ball 4422 and the retaining recess 7 form a retaining engagement. When the locking mechanism 4 is in the initial unlocked state, the locking ball 4422 abuts against the smooth rod of the slider 41; when the user drives the slider 41 to move until the locking ball 4422 is engaged in the locking recess 7 on the rod of the slider 41, the locking mechanism 4 completes the locking of the slider 41.

[0073] It is important to note that, in combination Figure 7 and Figure 8 As shown, because the driving member 42 always forms a sliding engagement with the tail section 355 and the abutting member 43 always forms a sliding engagement with the head section 353, the sliding member 41 will not rotate during the sliding process, that is, the spring retaining ball 44 can always form an elastic retaining engagement with the retaining recess 7 on the sliding member 41.

[0074] To further improve the locking effect of locking mechanism 4, combined with Figure 8 and Figure 10 As shown, the toothed claw 11 has an abutment groove 5 formed on its claw strip 111 along the circumference of the first pipe fitting 1. The abutment groove 5 makes the claw strip 111 a thin-walled structure. If the threaded section 12 is formed on the claw strip 111, the abutment groove 5 is controlled to occupy at least one-third of the length of the claw strip 111; if the threaded section 12 is formed on the pipe body of the first pipe fitting 1, the abutment groove 5 is controlled to occupy at least half the length of the claw strip 111, so that the abutment member 43 can abut against the abutment groove 5 of the claw strip 111. The abutment member 43 abutting against the thin-walled structure on the claw strip 111 can improve the deformation effect of the claw strip 111, thereby improving the tightness and force of the toothed claw 11 in wrapping the second pipe fitting 2.

[0075] It should be noted that in this embodiment, the locking mechanism 4 is arranged at only two opposite positions on the mounting sleeve 3, so that the user can complete the locking action more conveniently; if more than two sets of locking mechanisms 4 need to be arranged on the mounting sleeve 3, the multiple sets of locking mechanisms 4 are arranged at uniform angle intervals along the circumference of the mounting sleeve 3.

[0076] The implementation principle of Example 2 is as follows: the toothed claw 11 is gathered and fixed by the mounting sleeve 3, and the first pipe 1 is fixed by the toothed claw 11. At the same time, the mounting sleeve 3 is locked with the second pipe 2. A locking mechanism 4 operated by the user is set in the mounting sleeve 3. When the mounting sleeve 3 is tightened, the locking mechanism 4 increases the squeezing effect on the toothed claw 11, thereby improving the connection stability between the mounting sleeve 3 and the first pipe 1.

[0077] Example 3

[0078] A shower telescopic rod differs from Embodiment 2 in that the structure of the mounting sleeve 3 is different. In this embodiment, the locking mechanism 4 on the mounting sleeve 3 can achieve a semi-automatic locking function, without requiring the user to manually apply a large force; when the mounting sleeve 3 is tightened onto the threaded section 12 of the first pipe fitting 1, the semi-automatic automatic locking structure is triggered, and the locking mechanism 4 further locks the first pipe fitting 1 and the second pipe fitting 2.

[0079] Combination Figure 11 and Figure 12 As shown, in this embodiment, the locking mechanism 4 further includes a triggering device 6, which includes a locking pin 61. The locking pin 61 is mounted on the outer wall of the mounting sleeve 3 and inserted into the pull ring 421. In this embodiment, the elastic element used to drive the sliding member 41 is a second elastic element 46. The second elastic element 46 no longer drives the sliding member 41 to move towards the outside of the mounting sleeve 3, but instead drives the sliding member 41 to move towards the inside of the mounting sleeve 3. In the initial state, the locking pin 61 is inserted into the pull ring 421 to prevent the second elastic element 46 from driving the sliding member 41 to move. When the mounting sleeve 3 is tightened, the user pulls out the locking pin 61, and the second elastic element 46 drives the sliding member 41 to move until the abutment 43 is pressed shut. At the same time, the snap joint 442 of the spring retaining ball 44 snaps into the snap recess 7 of the sliding member 41, thereby locking the sliding member 41.

[0080] Combination Figure 11 and Figure 13As shown, specifically, a mounting ring 62 is fixed on the outer wall of the mounting sleeve 3 at a vertical or horizontal position located at the third opening 361. Taking the vertical direction as an example, a protrusion 621 extends from the inner wall of the mounting ring 62 toward the inside of the ring. The protrusion 621 is hemispherical. Correspondingly, the locking pin 61 is a vertically arranged long straight rod. A groove 611 is formed on the locking pin 61 along its length. The groove 611 and the protrusion 621 form an elastic locking engagement. After the protrusion 621 is engaged in the groove 611, it can slide along the groove 611. Thus, the locking pin 61 can slide vertically and insert into the pull ring 421 on the drive block to restrict the movement of the drive block. When the user needs to unlock the locking pin 61, he / she pulls out or pushes out the locking pin 61. The protrusion 621 can separate from the groove 611 to separate the locking pin 61 and the pull ring 421.

[0081] Additionally, refer to Figure 12 As shown, the elastic force of the second elastic member 46 and the third elastic member 441 needs to be limited. Although the third elastic member 441 drives the locking connector 442 to abut against the smooth rod of the sliding member 41, it does not restrict the second elastic member 46 from driving the sliding member 41 to move. When the sliding member 41 moves to the locking recess 7 of the locking connector 442 and the sliding member 41 to form a locking engagement, the second elastic member 46 cannot drive the sliding member 41 to separate from the locking connector 442. If you want to release the locking connector 442 from the sliding member 41, you need to drive the sliding member 41 to move through the pull ring 421 so that the locking connector 442 separates from the sliding member 41.

[0082] Example 4

[0083] Reference Figure 14 As shown, a shower telescopic rod differs from embodiments 2 and 3 in that the structure of the snap-fit ​​recess 7 is different.

[0084] Reference Figure 14 As shown in the embodiment of this application, the structural shape of the snap-fit ​​recess 7 is defined, so that the snap-fit ​​recess 7 has a multi-segment groove structure. The recessed surface of the snap-fit ​​recess 7 includes a recessed bottom surface 71 located at the center. The periphery of the recessed bottom surface 71 is formed with a spherical recessed surface 72 and a planar recessed surface 73. The planar recessed surface 73 includes a first inclined surface 731 and a second inclined surface 732. The two planar recessed surfaces 73 are arranged opposite to each other and are opened along the sliding direction of the slider 41, and the two planar recessed surfaces 73 are symmetrically arranged; the two spherical recessed surfaces 72 are also symmetrically arranged, but are opened on the left and right sides of the two planar recessed surfaces 73. The inclination angle of the first inclined surface 731 is smaller than the inclination angle of the second inclined surface 732, and the second inclined surface 732 is closer to the recessed bottom surface 71 of the snap-fit ​​recess 7 than the first inclined surface 731.

[0085] Combination Figure 9 and Figure 14 As shown, the recessed bottom surface 71 is a spherical surface. When the snap-fit ​​ball 4422 of the snap-fit ​​connector 442 is snapped into the snap-fit ​​recess 7, the recessed bottom surface 71 can fit against the spherical surface of the snap-fit ​​ball 4422. The spherical recessed surfaces 72 on the left and right sides of the recessed bottom surface 71, near the recessed bottom surface 71, can fit against the spherical surface of the snap-fit ​​ball 4422. As the spherical recessed surfaces 72 extend away from the recessed bottom surface 71, the spherical recessed surfaces 72 gradually separate from the spherical surface of the snap-fit ​​ball 4422, so that there is a gap between the snap-fit ​​ball 4422 and the left and right sides of the snap-fit ​​recess 7, which facilitates the snap-fit ​​ball 4422 to detach from the snap-fit ​​recess 7.

[0086] Combination Figure 9 and Figure 14 As shown, the bottom edge of the second inclined surface 732 is the arc edge of the recessed bottom surface 71, and the two sides of the second inclined surface 732 are straight edges that share the same edge as the spherical recessed surface 72. The second inclined surface 732 extends obliquely to the surface of the slider 41 and extends to the surface of the slider 41 to form a first inclined surface 731 with a small inclination angle. The first inclined surface 731 forms a guide groove along the direction of the slider 41, and the engaging ball 4422 can slide into the engaging recess 7 along the guide groove.

[0087] It should be noted that the vertical height of the second inclined surface 732 is one-third to one-half of the vertical height of the receiving ball 4422, so as to improve the limiting effect of the second inclined surface 732 on the receiving ball 4422, while the first inclined surface 731 mainly serves to guide the receiving ball 4422 into the receiving recess 7.

[0088] Example 5

[0089] A shower telescopic rod differs from embodiments 1-3 in that the mounting sleeve 3 itself is deformable. In this embodiment, the mounting sleeve 3 is made of an elastic material, such as POM or TPEE, and needs to simultaneously meet the requirements of machining and elastic deformation.

[0090] Combination Figure 3 and Figure 5 As shown, in this embodiment, the diameter of the first pipe 1 is slightly larger than the inner diameter of the mounting sleeve 3. After the mounting sleeve 3 is threadedly connected to the first pipe 1, the mounting sleeve 3 and the first pipe 1 form an interference fit. The first pipe 1 pushes outward to expand the end of the mounting sleeve 3 away from the second pipe 2, causing the mounting sleeve 3 to deform. One end of the mounting sleeve 3 expands outward, while the other end of the mounting sleeve 3 converges inward, so as to further tighten the claw strip 111 of the toothed claw 11, thereby improving the stability of the mounting sleeve 3 in locking the first pipe 1 and the second pipe 2.

[0091] It should be noted that the deformation of the mounting sleeve 3 is not a visible twisting or bending of the structure, but only an interference fit where one end expands outward and the other end contracts inward. This does not affect the normal operation of the locking mechanism 4 inside the mounting sleeve 3. Moreover, in this embodiment, the outer diameter of the first pipe 1 and the inner diameter of the mounting sleeve 3 need to be limited so that the first pipe 1 can squeeze the mounting sleeve 3 when it is inserted, and can also squeeze through without getting stuck in the mounting sleeve 3.

[0092] Example 6

[0093] Reference Figure 15 As shown, a shower telescopic rod differs from embodiments 1-3 and 5 in that a limiting structure 8 for further locking the second pipe 2 is added inside the first pipe 1.

[0094] Reference Figure 15 As shown in this embodiment, the limiting structure 8 includes a mounting cylinder 81 coaxially embedded in the inner wall of the first pipe fitting 1. The mounting cylinder 81 can be fixed inside the first pipe fitting 1 by a threaded connection. An elastic plastic cylinder 82 is bonded or laminated to the cylinder wall of the mounting cylinder 81. The inner wall of the elastic plastic cylinder 82 extends outward to form an elastic protrusion 821. The elastic protrusion 821 can form an elastic snap-fit ​​with the annular groove 21 on the pipe body of the second pipe fitting 2. When the second pipe fitting 2 is inserted into the first pipe fitting 1, the elastic protrusion 821 and the annular groove 21 form a snap-fit ​​to limit the second pipe fitting 2 from shaking or detaching from the first pipe fitting 1. This not only improves the stability of the connection between the mounting sleeve 3 and the first pipe fitting 1 and the second pipe fitting 2, but also plays an auxiliary fixing role.

[0095] It should be noted that the elastic protrusion 821 is annular, and the spacing between adjacent elastic protrusions 821 is the same as the spacing between the locking teeth 34 in Embodiment 1, so as to form a stable elastic locking fit with the annular groove 21 on the tube body of the second tube 2.

[0096] The implementation principle of Example 6 is as follows: the mounting sleeve 3 is used to gather and tighten the first pipe 1 and simultaneously form a snap-fit ​​with the second pipe 2, so that the first pipe 1, the second pipe 2 and the mounting sleeve 3 form an integral structure. The locking mechanism 4 is used to increase the gripping force of the mounting sleeve 3 in gathering and tightening the first pipe 1. Then, the mounting cylinder 81 inside the first pipe 1 achieves a snap-fit ​​with the second pipe 2, which further improves the stability of the overall structure formed by the three.

[0097] This application also discloses a shower device.

[0098] Reference Figure 16As shown, a shower device includes the aforementioned shower telescopic rod, wherein a mounting base 91 is integrally formed at the end of the first pipe fitting 1 away from the connection position of the two pipe fittings, and a pipe connector 92 is formed and connected at the end of the second pipe fitting 2 away from the connection position of the two pipe fittings. The mounting base 91 is used to fix the shower telescopic rod, while the pipe connector 92 is used to connect an external pipeline for the flow of shower water or to directly flow shower water.

[0099] Reference Figure 16 As shown, in this embodiment, the mounting base 91 has a mounting hole 911. The shower telescopic rod can be fixed to the ceiling wall of the bathroom by passing screws through the mounting hole 911. Of course, the mounting base 91 can also be detachably connected to the first pipe 1 by means of threaded connection, snap-fit ​​fixing, etc., and fixed at the required position such as the side wall or bottom wall, which can be determined according to the actual needs of the project.

[0100] Combination Figure 16 and Figure 17 As shown, in this embodiment, the pipe connector 92 includes a connector 921, which is a hollow structure. A water inlet connector 922 is connected to the bottom surface of the connector 921, a fixing connector 924 is installed on the top surface of the connector 921, and a water outlet connector 923 is connected to any other side surface of the connector 921. The water inlet connector 922, the fixing connector 924, and the water outlet connector 923 are all welded and fixed to the connector 921. The pipe connector 92 is made entirely of stainless steel. The water inlet connector 922 and the water outlet connector 923 can be connected to external pipes to achieve the purpose of water inlet from the bottom and water outlet from the side. The fixing connector 924 has an integrally formed fixing protrusion 925, which is arranged in a ring shape. Correspondingly, combined with… Figure 15 As shown, the inner wall of the end of the second pipe fitting 2 used for inserting into the fixed joint 924 is provided with an annular fixing groove 22. When the fixed joint 924 is inserted into the second pipe fitting 2, it forms a snap-fit ​​with the fixing groove 22 through the fixing protrusion 925, which can play a good role in preventing rotation and slippage, thereby achieving the purpose of improving the connection stability.

[0101] Combination Figure 16 and Figure 17 As shown, in this embodiment, the fixed connector 924 is welded and fixed to the connector 921, and the connector 921 is sealed. That is, the pipe connector 92 is not connected to the second pipe fitting 2. At this time, the shower head can be directly installed at the water outlet connector 923, and the shower water pipe is connected to the water inlet connector 922. Of course, the pipe connector 92 and the second pipe fitting 2 can also be connected, that is, the fixed connector 924, the second pipe fitting 2, and the connector 921 are connected. Figure 17 and Figure 18As shown, if the pipe joint 92 and the second pipe fitting 2 are connected, a shower water pipe can be installed in the shower telescopic rod and the pipe joint 92. In addition to being installed through the inlet joint 922 and the outlet joint 923, the installed shower water pipe can also be installed along the shower telescopic rod through the mounting base 91 and then connected to the external pipeline.

[0102] The shower device in this application has a pipe joint 92 that is bent at 90°. The pipe joint 92 is impacted by water flow, causing the shower telescopic rod connected to the pipe joint 92 to vibrate significantly. In addition, the shower telescopic rod itself may also vibrate during use. After long-term use, the mounting sleeve 3 may become loose and slip off. The locking mechanism 4 of the shower telescopic rod can effectively solve the above problems and improve the stability of the shower telescopic rod and the shower device.

[0103] The implementation principle of a shower device according to an embodiment of this application is as follows: a mounting base 91 and a pipe connector 92 are connected to the above-mentioned shower telescopic rod to achieve the purpose of fixing the telescopic rod and circulating shower water, while also meeting the requirements of adjusting the installation position of the telescopic rod, adjusting the length of the telescopic rod, and ensuring the stability and sealing of the telescopic rod connection.

[0104] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
