Description

Technical Field

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

[0002] An existing patent (publication number: CN212455851U) proposes a water utilization drainage pipe that is easy to install, including a first pipe and a second pipe, and a first connecting sleeve inserted into the outer side of the end of the first pipe. The end of the second pipe is inserted into the second connecting sleeve. The outer diameter of the first connecting sleeve is the same as the inner diameter of the second connecting sleeve. The length of the first pipe and the second pipe is 1m. However, in this device, "after the first pipe and the second pipe are respectively inserted into the first connecting sleeve and the second connecting sleeve, they are fixed with bolts." The pipe connection is fixed with bolts. Multiple bolts are tightened and disassembled one by one, which reduces the efficiency of operation. Moreover, the bolts are prone to loosening due to the impact of water flow in the pipe, causing leakage, which has drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a novel drainage pipe installation structure that employs a rotary locking and spring self-locking linkage mechanism. This mechanism facilitates easy assembly and disassembly without the need for special tools, thereby improving the efficiency of drainage pipe installation. Furthermore, through multiple sealing and anti-loosening designs, it prevents pipe leakage.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel drainage pipe installation structure includes a drainage pipe, a sealing ring, a threaded sleeve, a pressure plate, a lever plate, and a control ring. The drainage pipe has a left flange on the left side and a right flange on the right side. The right flange connects to the left flange to form a sealing groove, which is compatible with the sealing ring. The sealing ring connects to the sealing groove. The right flange has multiple positioning protrusions, and the left flange has multiple positioning grooves. The positioning protrusions are compatible with the positioning grooves and connect to the positioning grooves. The right flange is threadedly connected to the threaded sleeve, which is threadedly connected to the left flange. The left flange has a left fixing plate on its exterior. The right flange passes through the pressure plate, which fits against the outer side of the threaded sleeve. The inner side of the threaded sleeve fits against the left fixing plate. The threaded sleeve has multiple locking grooves, and the pressure plate has multiple locking blocks. The locking blocks are compatible with the locking grooves and connect to the locking grooves.

[0006] The right flange of this utility model has a right fixing plate on the outside, the right fixing plate has multiple fixing sleeves, the fixing sleeves have a slide rail inside, the pressure plate has multiple sliding rods, the sliding rods are adapted to the slide rails, the sliding rods are connected to the slide rails, and the sliding rods slide in the slide rails. The fixing sleeves have connecting rod through holes, the sliding rods have connecting rods, the connecting rods are adapted to the connecting rod through holes, the connecting rods pass through the spring strip and the connecting rod through holes in sequence, the outer end of the connecting rods is connected to a baffle, the baffle is fitted to the fixing sleeves, the fixing sleeves are connected to the outer end of the spring strips, and the inner end of the spring strips is connected to the sliding rods.

[0007] The right flange of this utility model has an external fitting control ring, and the control ring has an external mounting sleeve. The upper part of the mounting sleeve is connected to a mounting plate. The outer side of the mounting plate has a lever, and the inner side of the mounting plate has a lever.

[0008] The fixed support sleeve of this utility model has a sliding hole, and the sliding rod has a lever groove. The sliding hole and lever groove are adapted to the lever. The lever passes through the mounting support sleeve, the control ring and the sliding hole in sequence. The inner end of the lever is connected to the lever groove. The lever is connected to the mounting support sleeve by screws. The screws are connected to the mounting support sleeve and the lever in sequence. Beneficial effects

[0009] During the installation of drainage pipes, this utility model utilizes an external lever plate to move the control ring and lever, thereby controlling the locking block to disengage from the locking groove. Combined with the rotation of the threaded sleeve, this allows for quick and easy locking and fixing of the left and right flange joints, improving the efficiency of drainage pipe installation. Furthermore, the spring strip's own elastic tension automatically pushes the locking block of the pressure plate into the locking groove of the threaded sleeve after the external force on the lever plate disappears, providing self-locking positioning for the adjusted threaded sleeve. This prevents loosening and rotation under conditions such as water flow impact and pipe vibration, ensuring structural stability. The installation and disassembly are also convenient, requiring no special tools, making it particularly suitable for operations in confined spaces.

[0010] This utility model features a sealing ring embedded in a sealing groove. During the tightening process of the threaded sleeve, the right flange and the left flange are closely fitted and squeeze the sealing ring, allowing the sealing ring to fully fill the sealing groove and form a reliable sealing barrier to prevent leakage at the pipe connection. Furthermore, the positioning protrusion is embedded in the positioning groove, increasing the positioning support point between the right flange and the left flange. This facilitates the rapid axial concentric connection between adjacent drainage pipes. At the same time, the rigid fit eliminates radial displacement of the pipes, preventing the sealing ring from failing due to bias pressure caused by the connection deviation between drainage pipes.

[0011] This utility model adopts a linkage mechanism of rotary locking and spring self-locking, which makes disassembly and assembly convenient and does not require the use of special tools. It improves the efficiency of drainage pipe installation and avoids pipe leakage through multiple sealing and anti-loosening designs. The structure is reasonable. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0020] Example 1:

[0021] A novel drainage pipe installation structure includes a drainage pipe 01, a sealing ring 03, a threaded sleeve 08, a pressure plate 11, a lever plate 23, and a control ring 24. The drainage pipe 01 has a left flange 05 on its left side and a right flange 04 on its right side. The right flange 04 connects to the left flange 05 to form a sealing groove 02. The sealing groove 02 is compatible with the sealing ring 03, and the sealing ring 03 connects to the sealing groove 02. The right flange 04 has multiple positioning protrusions 09, and the left flange 05 has multiple positioning grooves 10. The positioning protrusions 09 are compatible with the positioning grooves 10 and connect to the positioning grooves 10. The right flange 04 is threadedly connected to the threaded sleeve 08, and the threaded sleeve 08 is threadedly connected to the left flange 05. The left flange 05 has a left fixing plate 07 on its exterior. The right flange 04 passes through the pressure plate 11, which fits against the outer side of the threaded sleeve 08. The inner side of the threaded sleeve 08 fits against the left fixing plate 07. The threaded sleeve 08 has multiple locking grooves 19, and the pressure plate 11 has multiple locking blocks 18. Locking block 18 is adapted to locking groove 19. Locking block 18 connects to locking groove 19. Sealing ring 03 is embedded in sealing groove 02. During the tightening process of threaded sleeve 08, right flange 04 and left flange 05 are closely attached and squeeze sealing ring 03, so that sealing ring 03 fully fills sealing groove 02, forming a reliable sealing barrier to prevent leakage at pipe connection. Positioning protrusion 09 is embedded in positioning groove 10, increasing the positioning support between right flange 04 and left flange 05. This facilitates quick axial concentric docking between adjacent drainage pipes 01, while eliminating radial displacement of pipes through rigid fitting, avoiding the failure of sealing ring 03 due to docking deviation between drainage pipes 01.

[0022] Example 2:

[0023] The right flange 04 of this utility model has a right fixing plate 06 on the outside, the right fixing plate 06 has multiple fixing sleeves 28, the fixing sleeves 28 have a slide rail 13 inside, the pressure plate 11 has multiple sliding rods 12, the sliding rods 12 are adapted to the slide rails 13, the sliding rods 12 are connected to the slide rails 13, and the sliding rods 12 slide within the slide rails 13. The fixing sleeves 28 have connecting rod through holes 17, the sliding rods 12 have connecting rods 16, the connecting rods 16 are adapted to the connecting rod through holes 17, the connecting rods 16 pass through the spring strip 14 and the connecting rod through holes 17 in sequence, the outer end of the connecting rods 16 is connected to a baffle 15, the baffle 15 is fitted to the fixing sleeves 28, the fixing sleeves 28 are connected to the outer end of the spring strips 14, and the inner end of the spring strips 14 is connected to the sliding rods 12.

[0024] Example 3:

[0025] The right flange 04 of this utility model has an externally fitted control ring 24. The control ring 24 has an externally fitted mounting sleeve 25. The upper part of the mounting sleeve 25 is connected to the mounting plate 26. The outer side of the mounting plate 26 has a lever 23, and the inner side of the mounting plate 26 has a lever 20. When the drainage pipe 01 is installed, the external lever 23 is moved to drive the control ring 24 and the lever 20 to move together, thereby controlling the locking block 18 to disengage from the locking groove 19. In conjunction with the rotation of the threaded sleeve 08, the joint of the left and right flanges can be quickly locked and fixed, improving the installation efficiency of the drainage pipe 01. The spring strip 14 has its own elastic tension. After the external force on the lever 23 disappears, it automatically pushes the locking block 18 of the pressure plate 11 into the locking groove 19 of the threaded sleeve 08, positioning and locking the adjusted threaded sleeve 08 to prevent it from loosening or rotating under the conditions of water flow impact and pipe vibration. This ensures the structural stability and makes disassembly and assembly convenient without the need for special tools, making it especially suitable for operation in narrow spaces.

[0026] Example 4:

[0027] The fixed support sleeve 28 of this utility model has a sliding hole 22, and the sliding rod 12 has a lever groove 21. The sliding hole 22 and the lever groove 21 are adapted to the lever 20. The lever 20 passes through the mounting support sleeve 25, the control ring 24, and the sliding hole 22 in sequence. The inner end of the lever 20 is connected to the lever groove 21. The lever 20 is connected to the mounting support sleeve 25 by screws 27. The screws 27 connect the mounting support sleeve 25 and the lever 20 in sequence. This device adopts a linkage mechanism of rotation locking and spring self-locking, which is convenient for disassembly and assembly, and does not require the use of special tools. It improves the installation efficiency of drainage pipe 01, and avoids pipe leakage through multiple sealing and anti-loosening designs. The structure is reasonable.

[0028] Example 5:

[0029] Installation steps: First, assemble the control structure of the pressure plate 11.

The lever 20 is fixed to the mounting sleeve 25 by the screw 27. For the fixed connection, the threaded sleeve 08 is finally fitted onto the outside of the right flange 04 and positioned therewith by threads. The threaded sleeve 08 is in contact with the pressure plate 11, and the locking block 18 is embedded in the locking groove 19. After the pressure plate 11 positioning structure is assembled, the sealing ring 03 is embedded in the sealing groove 02. Then, the adjacent drainage pipes 01 are placed axially concentrically, with the right flange 04 attached to the left flange 05. The positioning protrusion 09 is embedded in the positioning groove 10. Then, the pressure plate 11 is moved by the lever 23 until the locking block 18 is completely separated from the locking groove 19. The threaded sleeve 08 is rotated to move it to be in contact with the left fixed plate 07. The threaded sleeve 08 is wrapped around the outside of the right flange 04 and the left flange 05 and is fixedly connected to them by threads.
