[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, the safe, reliable, and efficient operation of water supply pipeline systems, as a crucial component of urban water supply, is receiving increasing attention. Currently, press-fit connections, as a quick connection method, are widely used in water supply pipe fittings due to their simple operation and good sealing performance. However, conventional press-fit fittings cannot achieve stepless expansion, limiting their application under complex installation conditions. When using conventional press-fit fittings to maintain pipelines, if extensive damage occurs, the fitting may be too short to install, severely impacting repair efficiency. This situation delays problem resolution, increases system damage, and wastes water resources.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a telescopic pipe fitting and piping system that aims to improve at least one of the problems mentioned in the background art.

[0005] The embodiments of this utility model can be implemented as follows:

[0036] like Figure 1 As shown, the telescopic connecting pipe 10 provided in this embodiment of the present invention includes a first telescopic pipe body 100, a second telescopic pipe body 200, and a retaining spring 300;

[0037] The first telescopic tube body 100 includes a first connecting section 110 and a first telescopic section 120 connected to each other. A boss 121 is provided around the end of the first telescopic section 120 away from the first connecting section 110. At least one first sealing groove 122 is provided on the boss 121, and a first sealing ring 123 is sleeved in each first sealing groove 122. A first retaining groove 124 is provided on the outer wall of the first telescopic section 120 near the first connecting section 110.

[0038] The second telescopic tube body 200 includes a second connecting section 210 and a second telescopic section 220 connected to each other. The second telescopic section 220 is sleeved on the outside of the boss 121. The outer wall of each first sealing ring 123 abuts against the inner wall of the second telescopic section 220. The second telescopic section 220 can move along the length direction of the first telescopic section 120. A second groove 224 is formed on the inner wall of the end of the second telescopic section 220 away from the second connecting section 210.

[0039] The first telescopic tube 100 and the second telescopic tube 200 include an extended state and a shortened state;

[0040] In the extended state, the first slot 124 is located outside the second telescopic section 220, and the retaining spring 300 is sleeved outside the first telescopic section 120 near the boss 121, with its outer periphery inserted into the second slot 224; in the shortened state, the first slot 124 is located inside the second telescopic section 220, the inner periphery of the retaining spring 300 is inserted into the first slot 124, and its outer periphery is inserted into the second slot 224.

[0041] The telescopic pipe fitting 10 provided by this utility model, due to the specific arrangement of the first telescopic pipe body 100 and the second telescopic pipe body 200, with the second pipe section 210 fitted outside the first pipe section 110, allows users to precisely control the installation length of the fitting through simple manual pushing, adapting to different installation and maintenance needs. This user-friendly design lowers the installation threshold, improves installation efficiency, reduces errors that may be caused by the use of complex tools, and enhances the convenience and flexibility of pipeline system maintenance. Figure 2As shown, when the second connecting section 210 slides to the rightmost end, the telescopic connecting fitting 10 reaches its maximum length. At this time, under the locking action of the retaining spring 300 by the second retaining groove 224 and the boss 121, the second connecting section 210 is prevented from detaching from the first connecting section 110. Water 13 flows inside the fitting. During the core stretching process, the inner diameter of the fitting increases accordingly. This change increases the flow rate while reducing the head loss along the pipeline system. This design optimizes the fluid dynamics characteristics and improves system efficiency. When the second connecting section 210 slides to the leftmost end, as... Figure 4 As shown, when the length of the telescopic connector reaches its shortest point, the length of the telescopic connector can be fixed to a certain extent and is not easily changed under the action of the snap ring 300 being engaged by the first snap groove 124 and the second snap groove 224.

[0042] Specifically, the retaining ring 300 is a metal ring with a notch. The retaining ring 300 is elastic. When the telescopic connector is at its longest length, the retaining ring 300 is spread out and fitted onto the outer wall of the first telescopic section 120. When the second telescopic section 220 slides to the shortened state, the retaining ring 300 reaches the first retaining groove 124 and shrinks under the action of elasticity to be embedded in the first retaining groove 124.

[0043] Optionally, to achieve a better sealing effect, the number of first sealing grooves 122 is at least two, and correspondingly, the number of first sealing rings 123 is also at least two.

[0044] Optionally, the first connecting section 110 and the first telescopic section 120 are connected by a convex ring 611. In the shortened state, the end face of the second telescopic section 220 abuts against the side of the convex ring 611 closest to the first telescopic section 120.

[0045] Optionally, the telescopic pipe fitting 10 also includes two sets of clamping components 400, which are respectively disposed outside the first pipe section 110 and the second pipe section 210, for connecting and clamping the pipe 11.

[0046] Optionally, each clamping assembly 400 includes a retaining ring 410 and a clamping sleeve 420;

[0047] The retaining ring 410 has a small-diameter first snap-fit ​​end 411 and a large-diameter second snap-fit ​​end 412. A snap-fit ​​groove 413 is provided on the first pipe section 110 and / or the second pipe section 210. The first snap-fit ​​end 411 snaps into the corresponding snap-fit ​​groove 413. One end of the clamping sleeve 420 has a snap-fit ​​ring 421 protruding from the circumference. The snap-fit ​​ring 421 snaps into the second snap-fit ​​end 412.

[0048] In use, the pipe 11 is inserted between the first connecting section 110 or the second connecting section 210 and the clamping sleeve 420. Then, the clamping tool 12 is used to deform the clamping sleeve 420, causing the clamping sleeve 420 to tightly press against the pipe 11. Figure 3 and Figure 5 As shown, Figure 3 This is a schematic diagram of the telescopic connector pressing the connector 11 in the extended state. Figure 4 This is a schematic diagram of the telescopic connecting pipe fitting pressing the connecting pipe 11 in the shortened state.

[0049] Optionally, an observation hole 423 is provided on the clamping sleeve 420 near the retaining ring 410. When the pipe 11 is inserted into the telescopic connector 10, the observation hole 423 can be used to observe whether the pipe 11 is inserted in place, ensuring the stability of the connection.

[0050] Optionally, the outer wall of the first pipe section 110 and / or the second pipe section 210 is provided with a plurality of second sealing grooves 511, and a second sealing ring 512 is fitted inside each second sealing groove 511.

[0051] When pipe 11 is compressed, the second sealing ring 512 is under compression with the inner wall of pipe 11, thereby achieving an effective sealing connection. This sealing effect ensures the integrity and leak-proof performance of the piping system.

[0052] Optionally, to achieve better connection stability between the pipe 11 and the connecting section, the outer wall of the first connecting section 110 and / or the second connecting section 210 is provided with multiple anti-slip teeth 513.

[0053] Optionally, to facilitate the insertion of the pipe 11, the end of each clamping sleeve 420 away from the snap ring 421 is a flared end 422.

[0054] This utility model provides a piping system including a telescopic connector 10 provided in this embodiment. Because this piping system includes the telescopic connector 10 provided in this embodiment, it is easy to install.

[0055] In summary, the telescopic connecting pipe provided in this embodiment of the present invention has the following characteristics:

[0056] 1. The second telescopic section 220 is fitted outside the first telescopic section 120. Users can adjust the length of the pipe by sliding the first telescopic section 120 or the second telescopic section 220. This design makes telescopic adjustment simple, convenient and efficient.

[0057] 2. The telescopic pipe fitting consists of a first telescopic pipe body 100 and a second telescopic pipe body 200, each having two sealing grooves for use with a sealing ring. A metal retaining ring 300 is also provided to prevent the first telescopic pipe body 100 and the second telescopic pipe body 200 from detaching from each other. This design optimizes sealing performance, ensuring good sealing at different telescopic lengths, thereby preventing leakage.

[0058] 3. The first expansion section 120 adopts a specially designed sealing groove, sealing ring and snap ring 300 structure, which makes the pipe fitting more adaptable and durable. The length can be manually adjusted according to the actual use, so as to adapt to different installation lengths and pipe layout requirements.

[0059] 4. The extension and retraction of the telescopic components can be precisely controlled by sliding the core. Users can easily increase or decrease the length of the pipe as needed without the need for professional tools.

[0060] 5. The clamping sleeve 420 is designed with an observation hole 423, which can be used to observe whether the pipe 11 has been inserted into place.

[0061] 6. The design of the entire telescopic pipe fitting 10 takes into account the compatibility with existing piping systems, making it easy to integrate into a variety of different piping system configurations, thus improving its market applicability.

[0062] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto.
