Piping systems, as a crucial component of building functions, run through multiple aspects, including water supply and drainage, HVAC, fire protection, and electrical systems. Their design and construction quality directly impact the building's performance and comfort. In piping engineering, the treatment of joints is particularly critical. Whether it's the rubber sealing ring socket joint of a PVC drain pipe, the flange gasket seal of a galvanized steel pipe, or the hot-melt welding of a PPR water pipe, the airtightness and durability of the joints must be ensured to prevent water and air leaks and the transmission of noise.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0027] In one embodiment, see Figure 1 and Figure 2 A sound insulation structure for construction projects includes a connector 1 and a pipe 2. The ends of the connector 1 are provided with access grooves 3 for inserting the pipe 2. The inner diameter of the access groove 3 is adapted to the outer diameter of the pipe 2. A push rod 6 is provided inside the access groove 3. The connector 1 is provided with a first cavity 7 and a second cavity 8 that are symmetrically distributed. The first cavity 7 and the second cavity 8 are both annular. The push rod 6 passes through the side wall of the connector 1 and extends into the first cavity 7. The push rod 6 is slidably connected to the side wall of the connector 1. A sealing mechanism 4 and a clamping mechanism 5 are provided inside the access groove 3. When the push rod 6 is pushed by the pipe 2, the sealing mechanism 4 is used to seal the pipe 2 and the connector 1, and the clamping mechanism 5 is used to fix the pipe 2.
[0028] In this embodiment, when connecting the pipes 2, the two pipes 2 are respectively inserted into the access grooves 3 at both ends of the connector 1. During the insertion process of the pipes 2, the ends of the pipes 2 will squeeze the push rod 6, causing the push rod 6 to move toward the inside of the first cavity 7, wherein the push rod 6 will fix the pipe 2 through the clamping mechanism 5 while moving. The thrust of the pipe 2 on the push rod 6 causes the clamping mechanism 5 to automatically fix the pipe 2, which can effectively improve the stability between the pipe 2 and the connector 1, and there is no need to connect the pipe 2 by manually operating the flange, which saves manpower and greatly improves the connection efficiency of the pipe 2. In addition, while the push rod 6 moves toward the inside of the first cavity 7, the gap between the connector 1 and the pipe 2 is sealed by the sealing mechanism 4. The sealing mechanism 4 can effectively improve the sealing performance between the connector 1 and the pipe 2, thereby reducing the noise transmitted through the gap by water flow, gas or vibration, and ensuring the sound insulation effect of the pipe 2.
[0029] See also Figure 3 The sealing mechanism 4 includes a mounting groove provided on the side wall of the access groove 3, an inflatable sealing ring 41 is installed inside the mounting groove, and the inflatable sealing ring 41 is connected to an air pipe 42, the other end of the air pipe 42 passes through the side wall of the mounting groove and extends to the inside of the first cavity 7, and one end of the air pipe 42 located inside the first cavity 7 is connected to an inflatable component, which is used to inflate the inside of the inflatable sealing ring 41;
[0030] When connecting the pipes 2, the two pipes 2 are respectively inserted into the access grooves 3 at both ends of the connector 1. During the insertion process of the pipes 2, the ends of the pipes 2 will squeeze the push rod 6, causing the push rod 6 to move toward the inside of the first cavity 7. While the push rod 6 moves, it will drive the inflation component to operate. The inflation component inputs gas into the inflatable sealing ring 41 through the air pipe 42, thereby causing the inflatable sealing ring 41 to expand. When the clamping mechanism 5 completes the fixation of the pipe 2, the outer wall of the inflatable sealing ring 41 fits tightly against the inner wall of the pipe 2. At this time, the inflatable sealing ring 41 seals the gap between the inner wall of the pipe 2 and the side wall of the access groove 3, thereby improving the sealing performance between the connector 1 and the pipe 2, thereby reducing the noise transmitted by water flow, gas or vibration through the gap, and ensuring the sound insulation effect of the pipe 2.
[0031] See also Figure 3The inflation assembly includes an airbag 45 fixed on the inner wall of the first cavity 7, a push plate 43 is provided on the side of the airbag 45 close to the push rod 6, and a symmetrically distributed guide rod 44 is fixed on the side wall of the push rod 6, wherein the inner wall of the first cavity 7 is provided with a symmetrically distributed guide groove adapted to the guide rod 44, the guide rod 44 is inserted into the guide groove and slidably connected to the inner wall of the guide groove, and a first elastic member 46 is provided on the outside of the guide rod 44, and the two ends of the first elastic member 46 are respectively fixedly connected to the side wall of the push plate 43 and the inner wall of the first cavity 7;
[0032] When connecting the pipes 2, the two pipes 2 are respectively inserted into the access grooves 3 at both ends of the connector 1. During the insertion process of the pipes 2, the ends of the pipes 2 will squeeze the push rod 6, causing the push rod 6 to move toward the inside of the first cavity 7. While the push rod 6 moves, it will squeeze the push plate 43, and the push plate 43 squeezes the airbag 45. After the airbag 45 is squeezed, the gas inside it will enter the inflatable sealing ring 41 through the trachea 42. The inflatable sealing ring 41 expands and fits tightly against the inner wall of the pipe 2, thereby achieving a sealing and sound insulation effect. The thrust of the pipe 2 on the push rod 6 is used to realize the self-sealing of the connector 1 and the pipe 2 Dynamic sealing does not require staff to operate other mechanisms to seal it, saving manpower and improving the connection efficiency of the pipeline 2. The guide groove can limit the push plate 43 through the guide rod 44, effectively improving the stability of the push plate 43 when moving. When the degree of extrusion of the push rod 6 on the push plate 43 is reduced, the first elastic member 46 can reset the push plate 43. The first elastic member 46 can be a spring, so that the push plate 43 no longer squeezes the airbag 45, and the gas inside the inflatable sealing ring 41 flows back to the inside of the airbag 45 through the air pipe 42, which is convenient for the staff to disassemble the connector 1 and the pipeline 2.
[0033] See also Figure 7 The clamping mechanism 5 includes a plurality of push rods 51 arranged inside the access groove 3 and distributed in a circumferential manner. The push rods 51 all penetrate the side walls of the access groove 3 and extend into the second cavity 8. The push rods 51 are slidably connected to the side walls of the access groove 3. A push plate 53 is fixed to one end of the push rod 51 located inside the second cavity 8, wherein a second elastic member 52 is provided outside the push rod 51, and the two ends of the second elastic member 52 are respectively fixedly connected to the inner wall of the second cavity 8 and the side wall of the push plate 53. An extrusion component is provided inside the second cavity 8, and the extrusion component is used to synchronously extrude the push plate 53;
[0034] When connecting the pipes 2, the two pipes 2 are respectively inserted into the access grooves 3 at both ends of the connector 1. During the insertion process of the pipes 2, the ends of the pipes 2 will squeeze the push rod 6. At this time, the push rod 6 will synchronously squeeze multiple abutment plates 53 through the extrusion assembly. The abutment plates 53 drive the abutment rod 51 toward the outer wall of the pipe 2 until the end of the abutment rod 51 is tightly fitted with the outer wall of the pipe 2. The connection between the pipe 2 and the connector 1 is completed by the thrust of the pipe 2 on the push rod 6, which can effectively improve the connection efficiency of the pipe 2 and save manpower. The multiple abutment rods 51 distributed circumferentially can clamp and fix the pipe 2 from multiple directions, effectively ensuring the stability between the pipe 2 and the connector 1.
[0035] See also Figure 5 and Figure 7 The extrusion assembly includes a plurality of trapezoidal blocks 54 arranged inside the second cavity 8 and distributed in a circumferential manner. The plurality of trapezoidal blocks 54 correspond one to one with the plurality of abutment plates 53. A threaded rod 55 is passed through the interior of each of the trapezoidal blocks 54. The threaded rod 55 is threadedly connected to the trapezoidal block 54. One end of the threaded rod 55 is rotatably connected to the inner wall of the second cavity 8. The other end of the threaded rod 55 passes through the side wall of the second cavity 8 and extends into the interior of the first cavity 7. One end of the threaded rod 55 located inside the first cavity 7 is connected to a rotating component, which is used to drive the plurality of threaded rods 55 to rotate synchronously.
[0036] When connecting the pipes 2, the two pipes 2 are respectively inserted into the access grooves 3 at both ends of the connector 1. During the insertion process of the pipes 2, the ends of the pipes 2 will squeeze the push rod 6. At this time, the push rod 6 drives multiple threaded rods 55 to rotate synchronously through the rotating parts, and the threaded connection between the threaded rod 55 and the trapezoidal block 54 drives the trapezoidal block 54 to move along the axis of the threaded rod 55. At this time, the trapezoidal block 54 can squeeze the abutment plate 53 through its inclined surface, so that the abutment plate 53 drives the abutment rod 51 to move toward the outer wall of the pipe 2, thereby completing the clamping and fixation of the pipe 2, and the threaded connection between the threaded rod 55 and the trapezoidal block 54 makes the trapezoidal block 54 have a self-locking function, thereby ensuring the squeezing effect of the trapezoidal block 54 on the abutment plate 53.
[0037] See also Figure 7 , a slide groove 56 adapted to the trapezoidal block 54 is provided on the inner wall of the second cavity 8, and the end of the trapezoidal block 54 is located inside the slide groove 56 and is slidably connected to the slide groove 56;
[0038] The slide groove 56 limits the trapezoidal block 54 so that the trapezoidal block 54 can only move along the axis of the threaded rod 55, avoiding the phenomenon that the threaded rod 55 rotates and drives the trapezoidal block 54 to rotate, and effectively ensures the stability of the trapezoidal block 54 during movement.
[0039] See also Figure 3 、 Figure 4 and Figure 5 The rotating component includes a rotating ring 59 arranged inside the first cavity 7, a first tooth group 58 is fixed on the outer wall of the rotating ring 59, a second tooth group 511 is fixed on the inner wall of the rotating ring 59, a first gear 57 is fixed to the end of the rotating rod, the first gear 57 is engaged with the first tooth group 58, a fixing plate 519 is fixed on the inner wall of the first cavity 7, a guide cylinder 518 passes through the fixing plate 519, and the guide is rotatably connected to the fixing plate 519, a second gear 510 is fixed to the outside of the guide cylinder 518, the second gear 510 is engaged with the second tooth group 511, the push rod 6 passes through the guide cylinder 518 and is slidably connected to the guide cylinder 518, wherein a spiral groove 520 is provided on the inner wall of the guide cylinder 518, and a protrusion 521 adapted to the spiral groove 520 is fixed to the outside of the push rod 6;
[0040] When connecting the pipes 2, the two pipes 2 are respectively inserted into the access grooves 3 at both ends of the connector 1. During the insertion process of the pipes 2, the ends of the pipes 2 will squeeze the push rod 6. At this time, the push rod 6 will drive the protrusions 521 on its surface to slide inside the spiral groove 520. The cooperation between the protrusions 521 and the spiral groove 520 causes the guide cylinder 518 to rotate, and the guide cylinder 518 drives the second gear 510 to rotate. The engagement of the second gear 510 with the second tooth group 511 drives the rotating ring 59 to rotate. The rotating ring 59 drives the threaded rod 55 to rotate through the engagement of the first tooth group 58 with the first gear 57, thereby enabling the threaded rod 55 to rotate synchronously.
[0041] See also Figure 4 A positioning block 522 is fixed inside the first cavity 7 and on the outer wall of the push rod 6. The positioning block 522 is fixedly connected to the limiting rod 517. The limiting rod 517 passes through the side wall of the first cavity 7 and is slidably connected thereto;
[0042] When the push rod 6 moves, it also drives the limit rod 517 to move through the positioning block 522. The side wall of the first cavity 7 limits the push rod 6 through the limit rod 517 and the positioning block 522, thereby avoiding the rotation of the push rod 6 and effectively ensuring the stability of the push rod 6 when moving. In addition, the positioning block 522 can also limit the push rod 6, thereby avoiding the push rod 6 from falling off from the inside of the connector 1 when the connector 1 is not in use.
[0043] See also Figure 5 and Figure 6 A limiting ring 512 is fixed on the side wall of the rotating ring 59, and a circular groove 513 adapted to the limiting ring 512 is provided on the inner wall of the first cavity 7. The outer wall of the limiting ring 512 is located inside the circular groove 513 and is slidably connected to the inner wall of the circular groove 513, wherein a positioning member is provided inside the circular groove 513 for positioning the limiting ring 512;
[0044] When the rotating ring 59 rotates, it also drives the limiting ring 512 to slide inside the circular groove 513. The circular groove 513 limits the rotating ring 59 through the limiting ring 512, thereby effectively improving the stability of the rotating ring 59 during rotation. A positioning piece is provided inside the circular groove 513. When the push rod 51 completes the fixation of the pipe 2, the positioning piece just completes the positioning of the limiting ring 512, effectively improving the stability of the rotating ring 59 and ensuring the fixing effect of the push rod 51 on the pipe 2.
[0045] See also Figure 6 The positioning member includes a pin 514 that passes through the side wall of the first cavity 7. The pin 514 is connected to the outer wall of the connector 1 through a third elastic member 516. A pin groove 515 that matches the pin 514 is provided on the outer wall of the limiting ring 512.
[0046] As the limiting ring 512 rotates, the end of the pin rod 514 will slide on the surface of the limiting ring 512. When the push rod 51 completes the fixation of the pipe 2, the end of the pin rod 514 will automatically enter the pin groove 515 under the action of the third elastic member 516. At this time, the pin rod 514 plays a positioning role on the limiting ring 512 through the pin groove 515, thereby effectively improving the stability of the limiting ring 512, wherein the third elastic member 516 can be a spring.
[0047] Working principle: When connecting the pipes 2, the two pipes 2 are respectively inserted into the access grooves 3 at both ends of the connector 1. During the insertion process of the pipes 2, the ends of the pipes 2 will squeeze the push rod 6, causing the push rod 6 to move toward the inside of the first cavity 7. At this time, the push rod 6 will drive the convex point 521 on its surface to slide inside the spiral groove 520. Through the cooperation between the convex point 521 and the spiral groove 520, the initial guide cylinder 518 rotates, and the guide cylinder 518 drives the second gear 510 to rotate, and the engagement between the second gear 510 and the second tooth group 511 drives the rotating ring 59 The rotating ring 59 drives the threaded rod 55 to rotate through the meshing of the first tooth group 58 and the first gear 57, thereby making the threaded rod 55 able to rotate synchronously, and the threaded connection between the threaded rod 55 and the trapezoidal block 54 drives the trapezoidal block 54 to move along the axis of the threaded rod 55. At this time, the trapezoidal block 54 can squeeze the push plate 53 through its inclined surface, so that the push plate 53 drives the push rod 51 to move toward the outer wall of the pipe 2 until the end of the push rod 51 is tightly fitted with the outer wall of the pipe 2, and the thrust of the pipe 2 on the push rod 6 is completed between the pipe 2 and the connector 1. The connection can effectively improve the connection efficiency of the pipe 2, wherein the rotating ring 59 rotates while driving the limit ring 512 to slide inside the circular groove 513. When the push rod 51 completes the fixation of the pipe 2, the end of the pin rod 514 will automatically enter the pin groove 515. At this time, the pin rod 514 plays a positioning role on the limit ring 512 through the pin groove 515, thereby effectively improving the stability of the limit ring 512 and ensuring the fixing effect of the push rod 51 on the pipe 2. In addition, the push rod 6 will also squeeze the push plate 43 while moving, and the push plate 43 will press the gas The airbag 45 is squeezed. After the airbag 45 is squeezed, the gas inside it will enter the inside of the inflatable sealing ring 41 through the trachea 42, and the inflatable sealing ring 41 will expand. When the push rod 51 completes the fixation of the pipe 2, the outer wall of the inflatable sealing ring 41 is tightly fitted with the inner wall of the pipe 2. At this time, the inflatable sealing ring 41 seals the gap between the inner wall of the pipe 2 and the side wall of the access groove 3, thereby improving the sealing performance between the connector 1 and the pipe 2, thereby reducing the noise transmitted by water flow, gas or vibration through the gap, and ensuring the sound insulation effect of the pipe 2.
