Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to pipe connection components used in building engineering. Background Technology

[0002] Pipelines in building construction are systems used to transport substances such as liquids, gases, or solid particles. They play a crucial role in building construction, and common types include water supply pipes, drainage pipes, and HVAC pipes. During the water diversion process in building construction, numerous drainage pipes are needed to achieve directional water flow. In the manufacturing process of drainage pipes, to facilitate transportation and installation, the pipes are often processed into several sections of varying lengths.

[0003] In existing technologies, water pipe sections are usually connected by welding. However, during long-term use, some water pipes may break. Since the broken water pipe section is welded to the adjacent water pipe sections on both sides, it cannot be disassembled and replaced separately. The only solution is to cut off the broken water pipe section and then weld a new water pipe section. This construction process is cumbersome, time-consuming, labor-intensive, and inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a pipe connection component for building engineering that facilitates the disassembly and replacement of water pipes, effectively solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A pipe connection assembly for building engineering includes a connecting sleeve, a pair of water pipe sections, and a pair of annular clamps. The connecting sleeve has insertion holes at both ends for the water pipe sections to be inserted. A connecting hole is provided inside the connecting sleeve, with both ends communicating with the insertion holes on both sides. Two water pipe sections are distributed on both sides of the connecting sleeve, with their middle ends correspondingly inserted into the insertion holes on both sides of the connecting sleeve. Two annular clamps are respectively fitted onto the water pipe sections on both sides. The connecting sleeve is equipped with a fastening device that moves the two annular clamps closer together to secure the two water pipe sections within the corresponding insertion holes, thus achieving the connection.

[0007] Therefore, by operating the fastening device to drive the two annular clamping parts away from each other and canceling the clamping on the water pipe section, the end of the water pipe section can be detached from the insertion hole, which is convenient for disassembly. Compared with the traditional welding and fixing method, the advantage of this application is that the two water pipe sections can be detached through this connecting component, which makes it convenient to replace the damaged water pipe section individually.

[0008] Furthermore, the fastening device includes a pair of annular mounting parts, a bidirectional threaded rod, and an adjusting mechanism. The two annular mounting parts are respectively fixedly fitted on the outer sides of the connecting sleeve. The bidirectional threaded rod is rotatably mounted on the two annular mounting parts. The adjusting mechanism is arranged on the connecting sleeve and is used to drive the bidirectional threaded rod to rotate. The two annular clamping parts are respectively provided with threaded holes that match the threads of the bidirectional threaded rod. The two ends of the bidirectional threaded rod are respectively matched and installed in the threaded holes on the two annular clamping parts. The two water pipe sections are respectively detachably installed with retaining rings by fastening screws. The outer diameter of the retaining ring is larger than the inner diameter of the annular clamping part, and the annular clamping part is correspondingly blocked by the retaining ring on the same side.

[0009] Furthermore, the adjustment mechanism includes a pair of brackets and a worm gear. The two brackets are fixed on the outer wall of the connecting sleeve, and the worm gear is rotatably mounted on the two brackets. A worm wheel is fixedly sleeved on the outside of the bidirectional threaded rod, and the worm wheel meshes with the worm gear.

[0010] Furthermore, three guide rods are fixedly connected to both annular mounting parts. The three guide rods are equidistantly distributed around the connecting sleeve. Each of the two annular clamping parts has three through guide holes. The three guide rods are respectively matched and inserted into the guide holes on the two annular clamping parts. When the guide rods are inserted into the guide holes one by one, the threaded holes and the bidirectional threaded rods are aligned.

[0011] Furthermore, each of the two annular mounting parts has a mounting hole, and two bearings are sleeved on the bidirectional threaded rod, with the two bearings correspondingly fitted into the two mounting holes.

[0012] Furthermore, a rocker plate is installed at one end of the worm gear, and the handle of the rocker plate has anti-slip texture.

[0013] Furthermore, a first rubber sealing ring is arranged around the insertion hole on the inner end wall of the two insertion holes. When the water pipe section is fastened in the insertion hole, the end face of the water pipe section is squeezed and in contact with the first rubber sealing ring.

[0014] Furthermore, the two end faces of the connecting sleeve are respectively arranged with second rubber sealing rings around the insertion hole. When the water pipe section is fastened in the insertion hole, the retaining ring is squeezed and abutted against the second rubber sealing ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] This invention uses a fastening device to drive two annular clamping parts away from each other, thus removing the pressure on the water pipe section and allowing the end of the water pipe section to be detached from the insertion hole for easy disassembly. Compared with the traditional welding and fixing method, the advantage of this application is that the two water pipe sections can be detachably connected through this connecting component, which facilitates the individual replacement of damaged water pipe sections.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-6 The present invention provides a pipe connection assembly for building engineering, comprising a connecting sleeve 1, a pair of water pipe sections 2, and a pair of annular clamping members 4. The connecting sleeve 1 has insertion holes 11 at both ends for the water pipe sections 2 to be inserted. The connecting sleeve 1 has a connecting hole 12, the two ends of which are connected to the insertion holes 11 on both sides. The two water pipe sections 2 are distributed on both sides of the connecting sleeve 1, and the middle ends of the two water pipe sections 2 are inserted into the insertion holes 11 on both sides of the connecting sleeve 1. The two annular clamping members 4 are respectively fitted on the water pipe sections 2 on both sides. The connecting sleeve 1 is provided with a fastening device 3, which is used to drive the two annular clamping members 4 to move closer to each other, so as to fasten the two water pipe sections 2 in the corresponding insertion holes 11 to achieve connection.

[0028] When connecting two water pipe sections 2, one end of each water pipe section 2 is inserted into the insertion holes 11 on both sides of the connecting sleeve 1. Then, two annular clamping pieces 4 are slidably fitted onto the two water pipe sections 2. Next, by operating the fastening device 3, the two annular clamping pieces 4 are driven to move closer together to achieve clamping, which firmly presses the two water pipe sections 2 into the insertion holes 11. The two water pipe sections 2 are connected through the connecting hole 12, thus achieving the connection of the two water pipe sections 2. If one of the water pipe sections 2 is damaged, by operating the fastening device 3, the two annular clamping pieces 4 are driven away from each other to release the pressure on the water pipe section 2, and the end of the water pipe section 2 can be removed from the insertion hole 11 for easy disassembly. Compared with the traditional welding fixing method, the advantage of this application is that the two water pipe sections 2 can be detachably connected through this connecting assembly, which facilitates the individual replacement of the damaged water pipe section 2.

[0029] Specifically, the fastening device 3 includes a pair of annular mounting parts 31, a bidirectional threaded rod 32, and an adjusting mechanism 33. The two annular mounting parts 31 are respectively fixedly fitted on the outer sides of the connecting sleeve 1. The bidirectional threaded rod 32 is rotatably mounted on the two annular mounting parts 31. The adjusting mechanism 33 is arranged on the connecting sleeve 1 and is used to drive the bidirectional threaded rod 32 to rotate. The two annular clamping parts 4 are respectively provided with threaded holes 34 that match the threads of the bidirectional threaded rod 32. The two ends of the bidirectional threaded rod 32 are respectively matched and installed in the threaded holes 34 on the two annular clamping parts 4. The two water pipe sections 2 are respectively detachably installed with retaining rings 21 by fastening screws. The outer diameter of the retaining ring 21 is larger than the inner diameter of the annular clamping part 4. The annular clamping part 4 is correspondingly blocked and engaged with the retaining ring 21 on the same side. When connecting the two water pipe sections 2, the annular clamping part 4 is first... The retaining ring 21 is then fitted onto the water pipe section 2 and secured with fastening screws. The end of the water pipe section 2 is then inserted into the insertion hole 11. Next, the threaded holes 34 on the two annular clamping members 4 are aligned with the two ends of the bidirectional threaded rod 32. The bidirectional threaded rod 32 is then rotated by the operating adjustment mechanism 33. The rotating bidirectional threaded rod 32 drives the two annular clamping members 4 closer together. The annular clamping members 4 and the side of the retaining ring 21 block and abut, pressing the water pipe section 2 tightly into the insertion hole 11. During disassembly, the bidirectional threaded rod 32 is reversed by operating the adjustment mechanism 33, driving the two annular clamping members 4 away from each other until they separate from the bidirectional threaded rod 32. Then, the retaining ring 21 is removed from the water pipe section 2, and the annular clamping members 4 are removed from the water pipe section 2, thus disassembling the water pipe section 2.

[0030] Specifically, the adjustment mechanism 33 includes a pair of brackets 331 and a worm gear 332. The two brackets 331 are fixed on the outer wall of the connecting sleeve 1. The worm gear 332 is rotatably mounted on the two brackets 331. A worm wheel 333 is fixedly sleeved on the outside of the bidirectional threaded rod 32. The worm wheel 333 meshes with the worm gear 332. By turning the worm gear 332, the rotating worm gear 332 meshes with and drives the worm wheel 333 to rotate. The worm wheel 333 drives the bidirectional threaded rod 32 to rotate, providing a driving adjustment function for the rotation of the bidirectional threaded rod 32.

[0031] Specifically, three guide rods 311 are fixedly connected to the two annular mounting parts 31. The three guide rods 311 are equidistantly distributed around the connecting sleeve 1. Each of the two annular clamping parts 4 has three through guide holes 312. The three guide rods 311 are respectively matched and inserted into the guide holes 312 on the two annular clamping parts 4. When the two annular clamping parts 4 are driven to approach each other, the guide rods 311 are matched and inserted into the guide holes 312 to play a guiding and limiting role, ensuring that the two annular clamping parts 4 move smoothly and stably. When the guide rods 311 are inserted into the guide holes 312 one by one, the threaded hole 34 and the bidirectional threaded rod 32 are aligned, which plays a positioning role and ensures that the bidirectional threaded rod 32 can be smoothly screwed into the threaded hole 34.

[0032] Specifically, each of the two annular mounting parts 31 has a mounting hole 321, and two bearings 322 are sleeved on the bidirectional threaded rod 32. The two bearings 322 are fitted into the two mounting holes 321 one by one. The bearings 322 are used to rotatably connect the bidirectional threaded rod 32 to the annular mounting part 31, ensuring that the rotation of the bidirectional threaded rod 32 is easy and stable enough, thus making the adjustment of the rotation of the bidirectional threaded rod 32 effortless.

[0033] Specifically, a rocker plate 334 is installed at one end of the worm gear 332. The handle of the rocker plate 334 is provided with anti-slip texture. By holding the handle of the rocker plate 334 and rocking the rocker plate 334, the worm gear 332 can be rotated, which makes it easier to apply force to adjust the rotation of the worm gear 332. The anti-slip texture on the outside of the rocker plate 334 increases the friction between it and the hand and prevents slipping when rocking.

[0034] Specifically, a first rubber sealing ring 101 is arranged around the inner end wall of the two insertion holes 11. When the water pipe section 2 is fastened in the insertion hole 11, the end face of the water pipe section 2 is squeezed and abutted against the first rubber sealing ring 101. The first layer of sealing effect is achieved by the squeezed and abutted against the end face of the water pipe section 2 and the first rubber sealing ring 101.

[0035] Specifically, the two end faces of the connecting sleeve 1 are respectively arranged with second rubber sealing rings 102 around the insertion hole 11. When the water pipe section 2 is fastened in the insertion hole 11, the retaining ring 21 is pressed against the second rubber sealing ring 102. The retaining ring 21 presses against the second rubber sealing ring 102 to achieve a second layer of sealing effect. The double sealing effect is better.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
