Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a drainage pipe connection structure. Background Technology

[0002] In the fields of construction and municipal engineering, the laying and connection of drainage pipes is a crucial step. In actual construction, due to design and construction errors or deformation of the building structure itself, there are often different spacings between the ports of the two drainage pipes to be connected. This uncertainty makes it impossible to use standard-sized rigid connectors for quick and effective connection.

[0003] A common solution is to measure the precise distance and angle between the two pipe ports on-site, and then customize special rigid connectors. The customization process is time-consuming and increases time and labor costs. To address these inconveniences, construction workers sometimes use a flexible hose (such as a rubber hose or corrugated pipe) for connection, utilizing its flexibility to compensate for deviations in spacing and angle. However, the water flow in the drainage pipe impacts the hose and, due to its own weight, causes it to sag, resulting in significant sagging deformation in the middle of the hose. Over time, this sagging not only creates a water accumulation area at the bottom of the hose, leading to impurities and pipe blockage, but also subjects the hose connection to additional stress, making it prone to loosening, leakage, or even breakage, severely affecting the stability and lifespan of the drainage system. Utility Model Content

[0004] In view of the problem that the existing connection structure can only be adapted to pipe connections with fixed spacing, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a drainage pipe connection structure that can adapt to different spacings, facilitate quick installation, and at the same time ensure connection stability and smooth drainage.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drainage pipe connection structure, including a variable length connecting pipe and a bracket that can be detachably installed on the variable length connecting pipe; The variable-length connecting pipe includes two end pipes, and a flexible hose is installed between the opposite faces of the two end pipes; The bracket includes two crossbeams, a lifting frame, and two semi-circular pressure strips. Locking seats are welded to both sides of the periphery of the end tube, and the locking seats and semi-circular pressure strips are detachably connected. Two connecting blocks and connecting strips are slidably installed on the opposite surfaces of the two crossbeams, and the connecting blocks and locking seats are detachably connected. The top of the lifting frame is provided with an arc-shaped cavity adapted to the curvature of the hose, and the lifting frame and connecting strips are detachably connected.

[0007] As an improved technical solution, weight-reducing cavities are provided at both ends of one side of the arc-shaped cavity.

[0008] As an improved technical solution, guide rails are installed on the opposite surfaces of the two crossbeams. The connecting block and the connecting strip have a groove on the side near the guide rail for the guide rail to pass through. A fourth threaded hole is provided on the connecting block and the connecting strip, and a wing bolt is threaded through the fourth threaded hole.

[0009] As an improved technical solution, the front and rear faces of the lifting frame are provided with second slots that engage with the connecting strip, and the two sides of both ends of the lifting frame are provided with second threaded holes that communicate with the second slots. The top ends of the connecting strip are provided with second fixing holes, and second locking screws are threaded onto the second threaded holes.

[0010] As an improved technical solution, the locking seat has a first slot on the end face away from the end tube, and the top of the locking seat has a first threaded hole at both ends that communicates with the first slot. The two ends of the semi-circular pressure strip are integrally connected with side protrusions, and the top of the side protrusions has a third threaded hole at both ends. The top of the connecting block has a first fixing hole on both sides, and the semi-circular pressure strip is threaded with a first locking bolt through the third threaded hole.

[0011] As an improved technical solution, the top of the locking seat is provided with a positioning insertion hole that communicates with the first slot between the two first threaded holes, the top of the connecting block is provided with an insertion hole communication hole between the two first fixing holes, and a positioning insertion rod that is inserted into the positioning insertion hole and the insertion hole communication hole is welded to the middle of the bottom of the side protrusion.

[0012] As an improved technical solution, the connecting strip has the same length as the support frame, and the locking seat, connecting block, and side protrusion strip have the same length.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, two end pipes are respectively connected to two pipes, and the hose is stretched. The length of the hose is adjustable. Its elastic expansion and contraction characteristics provide the necessary redundant length for the connection between the two pipe ports, which can effectively compensate for different spacing deviations within a certain range, realize the self-adaptation to non-standard spacing, and improve construction efficiency.

[0014] 2. In this utility model, the semi-circular pressure strip, locking seat and connecting block are fixed together by the first locking bolt, thereby suspending and fixing the bracket at the bottom of the hose to support the pipe and prevent it from falling under gravity, thus improving the stability of the drainage system. Furthermore, with the setting of the locking seat, semi-circular pressure strip and connecting block, the support frame is essentially locked between the two end pipes by force, without the need for external support for fixation, which makes the installation and operation of the support frame easier.

[0015] 3. This utility model provides the necessary redundant length for the connection between two pipe ports by utilizing the elastic expansion and contraction characteristics of the hose, which facilitates the rapid connection of the pipes. Furthermore, by fixing the bracket to the variable-length connecting pipe, the support bracket lifts the hose from the bottom, eliminating the unsupported hanging state of the hose, greatly reducing fatigue damage caused by long-term stress deformation, vibration and wear, and improving the stability of the drainage pipeline.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0021] Reference Figs. 1-3 This is the first embodiment of the present utility model, which provides a drainage pipe connection structure. This drainage pipe connection structure includes a variable length connecting pipe 1 and a bracket 2 that is detachably installed on the variable length connecting pipe 1. The variable length connecting pipe 1 includes two end pipes 3, and a flexible hose 4 is installed between the opposite faces of the two end pipes 3. The two end pipes 3 are respectively connected to two pipes, and the flexible hose 4 is stretched. The length of the flexible hose 4 is adjustable. Its elastic expansion and contraction characteristics provide the necessary redundant length for the connection between the two pipe ports, which can effectively compensate for different spacing deviations within a certain range, realize the self-adaptation to non-standard spacing, and improve construction efficiency. The bracket 2 includes two crossbeams 6, a lifting frame 7, and two semi-circular pressure strips 8. Locking seats 5 are welded to both sides of the periphery of the end tube 3, and the locking seats 5 and the semi-circular pressure strips 8 are detachably connected. Two connecting blocks 9 and connecting strips 10 are slidably installed on the opposite surfaces of the two crossbeams 6, and the connecting strips 10 are located between the two connecting blocks 9. At the same time, the connecting blocks 9 and the locking seats 5 are detachably connected. The top of the lifting frame 7 is provided with an arc-shaped cavity 71 that matches the curvature of the hose 4. The lifting frame 7 and the connecting strips 10 are detachably connected.

[0022] Weight reduction cavities 72 are provided at both ends of one side of the arc-shaped cavity 71. The weight reduction cavities 72 are used to reduce the overall weight of the support frame 7.

[0023] The front and rear faces of the support frame 7 are provided with second slots 73 that engage with the connecting strip 10. The two sides of both ends of the support frame 7 are provided with second threaded holes 74 that communicate with the second slots 73. The two ends of the top of the connecting strip 10 are provided with second fixing holes 11. A second locking screw 75 is threaded onto the second threaded hole 74 and passes through the interior of the second fixing hole 11.

[0024] The locking seat 5 has a first slot 51 on the end face away from the end tube 3. Both ends of the top of the locking seat 5 have a first threaded hole 53 that communicates with the first slot 51. Both ends of the semi-circular pressure strip 8 are integrally connected with a side protrusion 81. Both ends of the top of the side protrusion 81 have a third threaded hole. Both sides of the top of the connecting block 9 have a first fixing hole 92. The semi-circular pressure strip 8 is threaded with a first locking bolt 82 through the third threaded hole. The first locking bolt 82 passes through the first threaded hole 53 and the first fixing hole 92. At the same time, the first locking bolt 82 is threadedly connected to the first threaded hole 53.

[0025] With the locking seat 5, the semi-circular pressure strip 8 and the connecting block 9, the lifting frame 7 is essentially locked between the two end tubes 3 under force, without the need for external brackets for fixation, making the installation of the lifting frame 7 easier.

[0026] The top of the locking seat 5 is provided with a positioning insertion hole 52 that communicates with the first slot 51 between the two first threaded holes 53. The top of the connecting block 9 is provided with an insertion hole communication hole 91 between the two first fixing holes 92. The middle part of the bottom of the side protrusion 81 is welded with a positioning rod 83 that is inserted into the positioning insertion hole 52 and the insertion hole communication hole 91. When the bracket 2 is assembled, when the side protrusion 81 is placed on the locking seat 5, the positioning rod 83 passes through the interior of the positioning insertion hole 52 and the insertion hole communication hole 91 to achieve self-positioning between them, which is more conducive to the faster assembly of the bracket 2.

[0027] During use, the elastic expansion and contraction characteristics of the hose 4 provide the necessary redundant length for the connection between the two pipe ports, which facilitates the quick connection of the pipes. Furthermore, by fixing the bracket 2 to the variable length connecting pipe 1, the support frame 7 lifts the hose 4 from the bottom, eliminating the unsupported hanging state of the hose 4, greatly reducing the fatigue damage caused by long-term stress deformation, vibration and wear of the hose 4, and improving the stability of the drainage pipeline. Example 2

[0028] Reference Fig. 3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: guide rails are installed on the opposite surfaces of the two crossbeams 6, and the connecting block 9 and the connecting strip 10 are provided with a sliding groove for the guide rail to pass through on the side near the guide rail. The connecting block 9 and the connecting strip 10 are provided with a fourth threaded hole, and a wing bolt is threaded through the fourth threaded hole. One end of the wing bolt rubs against the outer wall surface of the guide rail to fix the connecting block 9 and the crossbeam 6, and the connecting strip 10 and the crossbeam 6.

[0029] The length of the connecting strip 10 is the same as that of the support frame 7, and the lengths of the locking seat 5, the connecting block 9 and the side protrusion 81 are the same. Since the lengths of the support frame 7 and the connecting strip 10, as well as the locking seat 5 and the connecting block 9 are the same, it is easier to quickly align the holes and make it easier to fix and lock them.

[0030] During use, both connecting block 9 and connecting strip 10 are slidably installed on crossbeam 6. Even if the lifting frame 7 is in a stretched state, the position of connecting block 9 and connecting strip 10 can be adjusted by sliding them on crossbeam 6, ensuring accurate locking and fixing between locking seat 5 and connecting block 9, and between lifting frame 7 and connecting strip 10. This is quite flexible. After the position of connecting block 9 and connecting strip 10 is adjusted, the tail end of the wing bolt abuts against the guide rail by rotating the wing bolt and the thread transmission of the fourth threaded hole, thus locking them together.

[0031] The remaining structure is the same as that in Example 1.

[0032] Based on embodiments 1-2, the working principle of this utility model is as follows: the two end tubes 3 are respectively connected to the two pipes, and the hose 4 is stretched; Place the lifting frame 7 below the hose 4 to lift the hose 4. Secure the connecting strip 10 inside the second slot 73. Normally, the connecting block 9 is secured inside the locking seat 5, thereby suspending the lifting frame 7 below the hose 4. Screw the second locking screw 75 into the second threaded hole 74 and through the second fixing hole 11, thereby fixing the lifting frame 7 and the connecting strip 10 together through the second locking screw 75. Place the semi-circular pressure strip 8 on top of the end pipe 3, and let the side protrusion strip 81 rest on the top of the locking seat 5. After passing the first locking bolt 82 through the third threaded hole on the side protrusion strip 81, continue to screw it into the interior of the first threaded hole 53 and the insertion hole 91. Fix the semi-circular pressure strip 8, the locking seat 5 and the connecting block 9 together with the first locking bolt 82, thereby suspending and fixing the bracket 2 at the bottom of the hose 4 to support the pipe, prevent it from falling due to gravity and improve the stability of the drainage system.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
