Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipeline connection, and in particular to a drainage pipeline joint. Background Art
[0002] Drainage pipes, as the name suggests, refer to pipes that collect and discharge sewage, wastewater and rainwater. By laying multiple sections of drainage pipes in sequence and connecting adjacent drainage pipes to each other, they can be combined with ancillary facilities to form a drainage system for drainage.
[0003] When laying drainage pipes, it is inevitable that they need to turn. In the prior art, the turning connection between two sections of drainage pipes usually uses a right-angle joint or a three-way joint. However, the angles of the right-angle joint and the three-way joint are both fixed right angles, and the scope of use is limited. When the angle between the two sections of drainage pipes is not a right angle, the above-mentioned joints cannot be used for connection, and it is necessary to re-customize a joint with a specific angle to connect the two sections of drainage pipes, which is inconvenient to use and needs to be improved. Utility Model Content
[0004] Based on this, the present application provides a drainage pipe joint that can conveniently connect two sections of drainage pipes set at an angle without the need to re-customize a joint with a specific angle, which helps to improve the efficiency of laying the drainage pipe.
[0005] The drainage pipe joint provided in this application adopts the following technical solution:
[0006] A drainage pipe joint, comprising a joint body, a first pipe section, a second pipe section and a positioning structure; wherein the joint body is in a disc shape and has a cavity inside, the outer circumference of the joint body is provided with a connecting hole and a sliding groove opening connected to the cavity, and the first pipe section is fixedly connected to the connecting hole;
[0007] The second pipe section is rotatably mounted at the slot opening, and two arc blocks are arranged on the outer circumference of the second pipe section. The two arc blocks are arranged at intervals and respectively abut against the inner and outer side walls of the joint body, and the two arc blocks always cover the slot opening;
[0008] The positioning structure is arranged outside the joint body and is used to fix the rotation position of the second pipe section.
[0009] By adopting the above-mentioned technical solution, the first pipe section and the second pipe section in the present application can be connected to the two sections of drainage pipes respectively. The first pipe section fixedly connected to the connecting hole always remains fixed to the joint body. The relative angle between the first pipe section and the second pipe section can be changed by moving the second pipe section in the slide groove, thereby being able to adapt to the connection between two sections of drainage pipes with different angles. There is no need to re-customize joints with specific angles, which helps to improve the efficiency of laying drainage pipes.
[0010] In addition, the setting of the two arc blocks can ensure the sealing effect of the joint body and reduce the possibility of liquid leakage; and the setting of the positioning structure can position and reinforce the second pipe section after the angle is determined, which is used to reduce the impact force on the second pipe section when the liquid impacts the second pipe section during the use of the drainage pipe, reduce the possibility of deformation of the second pipe section and causing liquid leakage, so as to extend the service life of the drainage pipe joint.
[0011] Optionally, the positioning structure is fixed to two mounting plates on two opposite sides of the joint body and a fastening component is detachably connected between the two mounting plates. The connection position of the fastening component to the mounting plate is adjustable, and the two fastening components are respectively against the outer peripheral surface of the second pipe section.
[0012] By adopting the above-mentioned technical solution, by setting two mounting plates to fix the fastening components, adjusting the positions of the two fastening components so that the two fastening components are respectively against the two opposite sides of the second pipe section, the position of the second pipe section relative to the first pipe section can be kept fixed, and the possibility of deformation of the second pipe section due to liquid impact can be reduced.
[0013] Optionally, each mounting plate is provided with an arc groove, and the fastening components include bolts and nuts. The bolts are passed through the two arc grooves, and a bolt cap is provided at one end of the bolt, which is pressed against one of the mounting plates; a threaded portion is provided at the other end of the bolt, and the nut is threadedly connected to the threaded portion, and the nut is pressed against the other mounting plate.
[0014] By adopting the above-mentioned technical solution, after the position of the second pipe section is determined, by passing the bolt through the two arcuate slide grooves, the bolt cap at the end of the bolt abuts against one of the mounting plates, and the nut is threadedly connected to the threaded portion of the bolt and abuts against the other mounting plate, the bolt can be kept firmly positioned and firmly abutted against the outer peripheral surface of the second pipe section, thereby reducing the possibility of the second pipe section being deformed by force.
[0015] Optionally, a plastic hose is provided inside the joint body, and the first pipe section and the second pipe section are respectively connected to two ends of the plastic hose.
[0016] By adopting the above technical solution, by setting a plastic hose to connect the first pipe section and the second pipe section, the flexible plastic hose can adapt to the rotation adjustment of the second pipe section, and the liquid in the drainage pipe directly enters the plastic hose instead of the joint body, which can reduce the pressure change during the liquid transportation process, that is, it is conducive to the smooth transportation of the liquid, and at the same time, it can also ensure the service life of the joint body. It is understandable that the flexible plastic hose is prone to local cracking and leakage. At this time, after the liquid enters the joint body and fills the cavity, the liquid can still be smoothly transported between the first pipe section and the second pipe section, which can effectively extend the service life of the drainage pipe joint.
[0017] Optionally, an elastic cotton pad is filled between the plastic hose and the inner wall of the connector body.
[0018] By adopting the above technical solution, the setting of the elastic cotton pad can always generate elastic force acting on the plastic hose, which can reduce the impact force acting on the plastic hose when the liquid flows through the plastic hose, thereby effectively extending the service life of the plastic hose and reducing the possibility of local cracking and leakage of the plastic hose.
[0019] Optionally, the arc block abutting against the inner wall of the joint body is set as a first arc block, and a movable slot is provided on the inner side of the first arc block; an abutment block is fixed to the side end wall of the slide slot, and the abutment block is always partially located in the movable slot.
[0020] By adopting the above-mentioned technical solution, through the cooperation of the abutment block and the movable slot, the second pipe section can always be in the slide groove mouth, and the arc block can always block the slide groove mouth, so as to ensure that the joint body maintains a good sealing effect and reduce the possibility of liquid leakage.
[0021] Optionally, a water-absorbent cotton felt is provided between the two arc-shaped blocks, and the water-absorbent cotton felt is bonded to the outer peripheral surface of the second pipe section.
[0022] By adopting the above-mentioned technical solution, the provision of the absorbent cotton felt can improve the sealing performance between the arc block and the slide groove opening, and reduce the occurrence of liquid leakage to the outside when flowing through the inside of the joint body.
[0023] Optionally, the end of the first pipe section / the end of the second pipe section is provided with a flange for connecting to a drainage pipe.
[0024] By adopting the above technical solution, the flange can facilitate the connection between the first pipe section / the second pipe section and the drainage pipe, thereby improving the convenience of disassembly and assembly between the drainage pipe joint and the two sections of the drainage pipe.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. By setting the first pipe section to keep it fixed with the joint body, and by setting the second pipe section to move it in the slide groove, the relative angle between the first pipe section and the second pipe section can be changed to adapt to the connection between the two sections of drainage pipes with different angles, which helps to improve the efficiency of laying drainage pipes;
[0027] 2. By setting the arc block to always cover the slot opening, and by setting the absorbent cotton felt between the two arc blocks, the joint body can maintain a good sealing effect and reduce the possibility of liquid leakage;
[0028] 3. By arranging two fastening components to abut against two opposite sides of the second pipe section respectively, the position of the second pipe section relative to the first pipe section can be kept fixed, and the possibility of deformation of the second pipe section due to liquid impact can be reduced.

[0034] The following is combined with Figure 1-4 This application is described in further detail.
[0035] Example 1
[0036] An embodiment of the present application discloses a drainage pipe joint.
[0037] Reference Figure 1 A drainage pipe joint, comprising a joint body 1, a first pipe section 2, a second pipe section 3 and a positioning structure 4; the joint body 1 is set in a disc shape, a cavity 11 is provided inside the joint body 1, and a connecting hole 12 and a slide groove opening 13 are opened on the outer peripheral surface of the joint body 1, and the connecting hole 12 is connected to the cavity 11; the outer diameter of the first pipe section 2 is the same as the inner diameter of the connecting hole 12, and after the first pipe section 2 is matched and inserted into the connecting hole 12, the first pipe section 2 and the joint body 1 can be fixed by welding or the like; an end of the first pipe section 2 away from the joint body 1 is provided with an integrally formed flange 7, and the flange 7 can facilitate the connection between the first pipe section 2 and the drainage pipe.
[0038] Also refer to Figure 2, the second pipe section 3 is rotatably installed in the slot opening 13, and the specific connection method is as follows: the outer peripheral surface of the second pipe section 3 is provided with two integrally formed arc blocks 31, the shape of the arc blocks 31 is the same as the shape of the outer peripheral wall of the joint body 1, and the two arc blocks 31 are arranged at intervals; after the second pipe section 3 is installed in the joint body 1, the inner arc surface of one arc block 31 can match and fit the outer peripheral wall of the joint body 1, and the outer arc surface of the other arc block 31 can match and fit the inner peripheral wall of the joint body 1, and the second pipe section 3 can smoothly rotate around the central axis of the joint body 1 through the movement of the arc block 31 on the outer peripheral surface of the joint body 1. It should be noted that the two arc blocks 31 in this embodiment can always cover the slot opening 13, so that the joint body 1 maintains a good sealing effect.
[0039] Reference Figure 3 The arc block 31 abutting against the inner circumferential wall of the joint body 1 is set as a first arc block 311, and an active slot 312 is opened on the inner side of the first arc block 311, and the active slot 312 is also set in an arc shape; an integrally formed abutment block 14 is fixed to the side end wall of the slide groove mouth 13, and the abutment block 14 partially extends into the active slot 312 and is always partially located inside the active slot 312, so that when the second pipe section 3 rotates to the extreme position along the slide groove mouth 13, the abutment block 14 can abut against the inner wall of the active slot 312 to limit the rotation position of the second pipe section 3 and ensure that the two arc blocks 31 always cover the slide groove mouth 13 to maintain a good sealing effect.
[0040] In addition, a water-absorbent cotton felt 32 is provided between the two arc blocks 31. The water-absorbent cotton felt 32 is made of flexible material and is bonded to the outer peripheral surface of the second pipe section 3. The provision of the water-absorbent cotton felt 32 can further improve the sealing performance between the arc block 31 and the slide groove mouth 13, and reduce the occurrence of liquid leakage to the outside when flowing through the inside of the joint body 1.
[0041] Back to Figure 1 An end of the first pipe section 2 away from the joint body 1 is also provided with an integrally formed flange 7, which can facilitate the connection between the second pipe section 3 and the drainage pipe; and a positioning structure 4 is arranged on the outside of the joint body 1. The positioning structure 4 can position and reinforce the second pipe section 3 after the rotation position of the second pipe section 3 is determined, so as to reduce the impact force on the second pipe section 3 during the use of the drainage pipe, and reduce the possibility of deformation of the second pipe section 3 and liquid leakage.
[0042] Specifically, refer to Figure 4The positioning structure 4 includes two mounting plates 41 fixed to two opposite sides of the joint body 1 and a fastening component 42 detachably connected between the two mounting plates 41. Each mounting plate 41 is provided with an arc groove 411, and the arc axis of the arc groove 411 coincides with the central axis of the joint body 1. There are two groups of fastening components 42, and the two groups of fastening components 42 are respectively against the outer peripheral surface of the second pipe section 3.
[0043] The fastening component 42 includes a bolt 43 and a nut 44. The bolt 43 is matched and inserted into two arc grooves 411, and can move in the arc grooves 411 to achieve adjustable connection position of the fastening component 42 and the mounting plate 41. A bolt cap 431 is provided at one end of the bolt 43, and the bolt cap 431 can be pressed against one of the mounting plates 41. A threaded portion 432 is provided at one end of the bolt 43 away from the bolt cap 431. By threading the nut 44 into the threaded portion 432 and pressing the nut against the other mounting plate 41, the bolt 43 can be kept firmly positioned. By adjusting the position of the bolt 43 so that it is firmly pressed against the outer peripheral surface of the second pipe section 3, the second pipe section 3 can be supported and unloaded, and the possibility of deformation of the second pipe section 3 due to stress can be reduced.
[0044] The implementation principle of Example 1 of the present application is:
[0045] When laying the drainage pipe, the relative angle between the first pipe section 2 and the second pipe section 3 is adjusted by moving the second pipe section 3 in the slide groove mouth 13; after the angle adjustment is completed, the two sections of the drainage pipe are respectively connected to the first pipe section 2 and the second pipe section 3, and then the bolts 43 are passed through the two arc slide grooves 411, so that the two bolts 43 are respectively abutted against the outer circumferential surface of the second pipe section 3, and then the nuts 44 are connected to the threaded portions 432 of the bolts 43 and locked. This can firmly position the second pipe section 3 to adapt to the connection between two sections of drainage pipes with different angles, without the need to re-customize joints with specific angles, which helps to improve the efficiency of laying the drainage pipe.
[0046] Example 2
[0047] An embodiment of the present application discloses a drainage pipe joint.
[0048] The embodiment of the present application discloses a drainage pipe joint, and the remaining components are the same as those of the embodiment 1, and are not described one by one here; the difference from the embodiment 1 is that a plastic hose is provided inside the joint body 1 of the present embodiment, one end of the plastic hose is connected to the first pipe section 2, and the other end of the plastic hose is connected to the second pipe section 3. The setting of the plastic hose can adapt to the rotation adjustment of the second pipe section 3, and can reduce the pressure change during the liquid transportation process, that is, it is conducive to the smooth transportation of the liquid.
[0049] In addition, an elastic cotton pad is filled between the plastic hose and the inside of the joint body 1. The elastic cotton pad can always generate elastic force acting on the plastic hose, which can reduce the impact force acting on the plastic hose when the liquid flows through the plastic hose, thereby effectively extending the service life of the plastic hose and reducing the possibility of local cracking and leakage of the plastic hose.
[0050] The implementation principle of Example 2 of the present application is:
[0051] The plastic hose connected between the first pipe section 2 and the second pipe section 3 can adapt to the rotation adjustment of the second pipe section 3, and during the drainage process, the liquid in the drainage pipe directly enters the plastic hose instead of the joint body 1, which can reduce the pressure change during the liquid transportation process, that is, it is conducive to the smooth transportation of the liquid, and can also ensure the service life of the joint body 1. In addition, when the plastic hose is partially cracked or leaked, the leaked liquid can enter the inside of the joint body 1 and be stored in the cavity 11. When the cavity 11 is full, the liquid can still be smoothly transported between the first pipe section 2 and the second pipe section 3, which can effectively extend the service life of the drainage pipe joint.
[0052] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
