Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, and more specifically, it relates to a leak-proof device for drainage pipe interfaces. Background Art

[0002] With the development of urban construction, in order to avoid the impact of rainwater or sewage on the city, rain and sewage pipes are usually laid on the ground or underground during the construction of the city, and the rain and sewage in the city are discharged through the rain and sewage pipes.

[0003] Publication No. CN218719502U discloses a leak-proof pipe, and its technical solution includes a pipe body. Connecting rings are installed at one end of each pipe body. Through holes are formed on the surface of the connecting rings. Hexagon socket head cap screws are sleeved inside the through holes, and hexagon nuts are sleeved on the surfaces of the hexagon socket head cap screws.

[0004] In the above technical solution, after the two connecting rings are fixed together by the hexagon socket head cap screws, the arc-shaped fasteners are buckled outside the two connecting rings, and the hexagon head bolts are passed through the round holes and screwed into the threaded cylinders to fix the two arc-shaped fasteners together, so as to avoid the problem that the hexagon bolts and the hexagon socket head cap screws become loose after the pipe body is used with long-term shaking. However, in the installation process of the above technical solution, the hexagon nuts need to be placed in the hexagon grooves, and then several hexagon head bolts are connected to the hexagon nuts one by one. The installation process is too cumbersome and affects the work efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a leak-proof device for drainage pipe interfaces, which solves the problem that the installation process is too cumbersome when using bolts and nuts to connect each other during the pipe installation, affecting the work efficiency.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: A leak-proof device for drainage pipe interfaces includes two pipe bodies connected to each other. A rotating plate one and a rotating plate two that are rotatably connected to each other are arranged between the two pipe bodies. The longitudinal sections of the rotating plate one and the rotating plate two are arc-shaped. Positioning blocks are fixedly connected to the inner side walls of the rotating plate one and the rotating plate two. Positioning grooves for inserting the positioning blocks are formed on the outer side walls of the two pipe bodies. Rubber layers are fixedly connected to the inner side walls of the rotating plate one and the rotating plate two. The rotating plate one and the rotating plate two are connected by an adjusting component.

[0008] By adopting the above technical scheme, when the two pipe bodies need to be connected to each other, the restriction between the rotating plate one and the rotating plate two is cancelled by the adjusting component, and then the rotating plate one is rotated to drive the rotating plate one and the rotating plate two to separate from each other, and then the positioning block on the inner wall of the rotating plate two is inserted into the positioning groove on the outer wall of the two pipe bodies, and at the same time, the rotating plate two and the side walls of the two pipe bodies are driven to fit each other, and then the rotating plate is driven to start rotating and return to its original position again, and at the same time, the positioning block on the inner wall of the rotating plate one is driven to insert into the positioning groove on the outer wall of the two pipes. At this time, the rotating plate one and the rotating plate two can be fixed to each other by the adjusting component, so as to achieve the effect of installing the two pipes to each other without connecting the hexagonal bolts and the hexagonal nuts one by one, thereby reducing the operation steps during installation and improving work efficiency. At the same time, by setting the rubber layer, the sealing effect between the rotating plate one and the rotating plate two and the two pipe bodies can be improved to avoid water leakage in the pipe.

[0009] The utility model is further configured as follows: the adjusting assembly includes a fixed plate 1 fixedly connected to one side wall of the rotating plate and a fixed plate 2 rotatably connected to the side wall of the rotating plate 2; a transmission rod is rotatably connected between the fixed plate 1 and the fixed plate 2; a connecting piece is provided on one side wall of the fixed plate; the transmission rod respectively penetrates the fixed plate 1, the fixed plate 2, and the connecting piece and is fixedly connected to the connecting piece; a limiting groove for sliding the transmission rod is provided on the fixed plate 1; and a driving member for driving the fixed plate 2 and the fixed plate 1 to abut against each other is provided on the end of the transmission rod away from the connecting piece.

[0010] When the cam is in the state of being moved away from the stopper, the first and second plates are moved in a direction opposite to each other, and the second plate is moved in a direction opposite to the stopper, thereby achieving the effect of connecting the cam and the second plate to each other.

[0011] The present utility model is further configured as follows: The driving member includes an adjusting block rotatably connected to one end of the transmission rod away from the connecting piece. A gasket is provided between the adjusting block and the second fixing plate. A through groove for the transmission rod to slide is formed in the side wall of the gasket. The two sides of the gasket are respectively in mutual contact with the side wall of the second fixing plate and the adjusting block. A handle is fixedly connected to the side wall of the adjusting block. A convex block for the side wall of the adjusting block to slide is fixedly connected to the side of the gasket close to the adjusting block. When the adjusting block and the convex block are in mutual contact, the second fixing plate and the connecting piece are in mutual abutment.

[0012] By adopting the above technical solution, when it is necessary to drive the first fixing plate and the second fixing plate to cancel the abutment, rotate the handle to drive the handle to drive the adjusting block to start rotating. At the same time, since the adjusting block is in mutual contact with the side wall of the gasket and the gasket is provided with a through groove for the transmission rod to slide, the adjusting block will drive the gasket to start sliding, and at the same time drive the adjusting block to be separated from the convex block on the gasket. At this time, the connecting piece and the second fixing plate are separated from each other, and at the same time, the connection between the first fixing plate and the second fixing plate loses the restriction of the connecting piece, driving the first fixing plate and the second fixing plate to cancel the abutment. When it is necessary to drive the first fixing plate and the second fixing plate to abut against each other, rotate the handle again to drive the handle back to its original position. At the same time, the handle drives the adjusting block to start rotating. At this time, the gasket starts to move under the influence of the adjusting block, and drives the adjusting block to be in mutual contact with the convex block, and at the same time drives the connecting piece to be in mutual abutment with the second fixing plate. At this time, the second fixing plate is subjected to the pressure applied by the connecting piece, so that the first fixing plate and the second fixing plate are in mutual abutment, thereby achieving the effect of abutting the first fixing plate and the second fixing plate against each other.

[0013] The present utility model is further configured as follows: The longitudinal section of the handle is in a "C" shape. When the first fixing plate and the second fixing plate are in mutual contact, the end of the handle away from the adjusting block is in mutual contact with the side wall of the connecting piece.

[0014] By adopting the above technical solution, further defining the shape of the handle can facilitate driving the handle to drive the adjusting block to rotate. At the same time, after the first fixing plate and the second fixing plate are abutted against each other, the handle can be driven to be in mutual contact with the side wall of the connecting piece, improving the fixing effect between the connecting piece and the first fixing plate and avoiding the separation of the connecting piece and the transmission rod.

[0015] The present utility model is further configured as follows: A rotating groove for the transmission rod to slide is formed in the side wall of the adjusting block. A connecting rod is fixedly connected in the rotating groove. The connecting rod penetrates through the transmission rod and is rotatably connected to the transmission rod.

Through the arrangement of the rotating groove and the connecting rod, it is convenient to drive the problem of mutual rotation between the adjusting block and the transmission rod. At the same time, it can also avoid the problem of separation between the adjusting block and the transmission rod when they rotate, improving the stability.

[0017] The present utility model is further configured such that: anti-slip patterns are provided on both the connecting piece and one side wall of the fixed plate.

[0019] The present utility model is further configured such that: a spring hinge is fixedly connected between the second fixed plate and the second rotating plate, and when the spring hinge is in a natural state, the second fixed plate is horizontally arranged.

[0020] By adopting the above technical solution, the connection mode between the second fixed plate and the second rotating plate is further defined. Through the setting of the spring hinge, it is convenient to drive the second fixed plate to rotate on the side wall of the second rotating plate.

[0021] The present utility model is further configured such that: a rotating block is fixedly connected to one side wall of the first rotating plate, a groove for the rotating block to rotate is formed on the side wall of the second rotating plate, a rotating rod is rotatably connected to the side wall of the second rotating plate, and the rotating rod penetrates through the second rotating plate and the rotating block and is fixedly connected to the second rotating plate and the rotating block.

The rotating plate one 2 and the rotating plate two 3 are connected by an adjusting component. When it is necessary to connect the two pipe bodies 1 to each other, the restriction between the rotating plate one 2 and the rotating plate two 3 is cancelled through the adjusting component. Then, the rotating plate one 2 is rotated to drive the rotating plate one 2 and the rotating plate two 3 to separate from each other.

At this time, the rotating plate one 2 and the rotating plate two 3 can be fixed to each other through the adjusting component, so as to achieve the effect of installing the two pipes without connecting the hex bolts to the hex nuts one by one, reducing the operation steps during installation, improving work efficiency, and at the same time, through the setting of the rubber layer 6, the sealing effect between the rotating plate one 2 and the rotating plate two 3 and the two pipe bodies 1 can be improved, avoiding the situation of water leakage in the pipes.

[0037] As Figures 1 - 8 As shown in the figure, the adjusting component includes a fixing plate one 7 fixedly connected to the side wall of the rotating plate one 2 and a fixing plate two 8 rotatably connected to the side wall of the rotating plate two 3. A transmission rod 9 is rotatably connected between the fixing plate one 7 and the fixing plate two 8. A connecting piece 10 is provided on the side wall of the fixing plate one 7. The transmission rod 9 passes through the fixing plate one 7, the fixing plate two 8, and the connecting piece 10 respectively and is fixedly connected to the connecting piece 10. A limiting groove 11 for the transmission rod 9 to slide is opened on the fixing plate one 7. A driving member for driving the fixing plate two 8 and the fixing plate one 7 to abut against each other is provided at one end of the transmission rod 9 away from the connecting piece 10. The driving member includes an adjusting block 12 rotatably connected to one end of the transmission rod 9 away from the connecting piece 10. A gasket 13 is provided between the adjusting block 12 and the fixing plate two 8. A through groove 14 for the transmission rod 9 to slide is opened on the side wall of the gasket 13. The two sides of the gasket 13 are respectively in contact with the side walls of the fixing plate two 8 and the adjusting block 12. A handle 15 is fixedly connected to the side wall of the adjusting block 12. A convex block 16 for the side wall of the adjusting block 12 to slide is fixedly connected to one side of the gasket 13 close to the adjusting block 12. When the adjusting block 12 and the convex block 16 are in contact with each other, the fixing plate two 8 and the connecting piece 10 are in abutment with each other.

[0038] When it is necessary to separate the rotating plate 12 from the rotating plate 2 3, the handle 15 is turned to drive the handle 15 to drive the adjusting block 12 to start rotating. At the same time, since the adjusting block 12 and the side walls of the gasket 13 are in contact with each other and the gasket 13 is provided with a through groove 14 for the transmission rod 9 to slide, the adjusting block 12 will drive the gasket 13 to start sliding, and at the same time, the protrusions 16 on the adjusting block 12 and the gasket 13 are driven to separate from each other. At this time, the connecting piece 10 and the fixed plate 2 8 are separated from each other, and at the same time, the restriction of the connecting piece 10 is lost between the fixed plate 1 7 and the fixed plate 2 8, and the fixed plate 1 7 and the fixed plate 2 8 are driven to cancel the abutment, and then the fixed plate 2 8 is driven to start rotating. At the same time, the fixed plate 2 8 drives the transmission rod 9 to start moving along the side wall of the limiting groove 11 and disengage from the limiting groove 11. At this time, the transmission rod 9 drives the connecting piece 10 to start moving in the same direction, and drives the connecting piece 10 to separate from the side wall of the fixed plate 1 7. At this time, the fixed plate 1 7 loses its restriction and can drive the rotating plate 2 to start rotating.

[0039] When it is necessary to fix the rotating plate 1 2 and the rotating plate 2 3 to each other, the handle 15 is rotated again to drive the handle 15 back to its original position, and the handle 15 drives the adjusting block 12 to start rotating. At this time, the gasket 13 begins to move under the influence of the adjusting block 12, and drives the adjusting block 12 to contact with each other and drives the connecting piece 10 and the fixing plate 2 8 to abut against each other. At this time, the fixing plate 2 8 is subjected to the pressure applied by the connecting piece 10, so that the fixing plate 1 7 and the fixing plate 2 8 abut against each other, and then the rotating plate 1 2 is rotated back to its original position, and then the fixing plate 2 8 is driven back to its original position, and at the same time, the transmission rod 9 is driven to enter the limiting groove 11. At this time, the transmission rod 9 drives the connecting piece 10 to start moving in the same direction, and drives the connecting piece 10 to contact with the side wall of the fixing plate 1 7, and then the driving member is started to drive the fixing plate 1 7 and the fixing plate 2 8 to abut against each other, so as to achieve the effect of connecting the rotating plate 1 2 and the rotating plate 2 3 to each other.

[0040] like Figures 1 - 8 As shown, the handle 15 is set in a "C" shape in longitudinal section. When the fixing plate 17 and the fixing plate 2 8 are in contact with each other, the end of the handle 15 away from the adjusting block 12 is in contact with the side wall of the connecting piece 10, which can facilitate the handle 15 to drive the adjusting block 12 to rotate. At the same time, after the fixing plate 17 and the fixing plate 2 8 are abutted against each other, the handle 15 can be driven to contact the side wall of the connecting piece 10, thereby improving the fixing effect between the connecting piece 10 and the fixing plate 17 and avoiding the connection piece 10 and the transmission rod 9 from being separated from each other. A rotating groove 17 for sliding the transmission rod 9 is provided on the side wall of the adjusting block 12. A connecting rod 18 is fixedly connected in the rotating groove 17. The connecting rod 18 penetrates the transmission rod 9 and is rotatably connected to the transmission rod 9. Through the arrangement of the rotating groove 17 and the connecting rod 18, the problem of driving the adjusting block 12 and the transmission rod 9 to rotate with each other can be facilitated. At the same time, the problem of separation of the adjusting block 12 and the transmission rod 9 when the adjusting block 12 and the transmission rod 9 rotate can be avoided, thereby improving stability.

[0041] like Figures 1 - 8 As shown, the side walls of the connecting piece 10 and the fixing plate 7 are both provided with anti-slip grooves 23, which can increase the friction between the connecting piece 10 and the fixing plate 7, and further improve the fixing effect between the connecting piece 10 and the fixing plate 7.

[0042] like Figures 1 - 8 As shown, a spring hinge 19 is fixedly connected between the fixed plate 28 and the rotating plate 23. When the spring hinge 19 is in a natural state, the fixed plate 28 is horizontally arranged. Through the arrangement of the spring hinge 19, the fixed plate 28 can be easily driven to rotate on the side wall of the rotating plate 23.

[0043] like Figures 1 - 8 As shown, the side wall of the rotating plate 1 2 is fixedly connected to a rotating block 20, the side wall of the rotating plate 2 3 is provided with a groove 21 for the rotating block 20 to rotate, the side wall of the rotating plate 2 3 is rotatably connected to a rotating rod 22, the rotating rod 22 passes through the rotating plate 2 3 and the rotating block 20 and is fixedly connected to the rotating plate 2 3 and the rotating block 20, which can facilitate the driving of the rotating plate 1 2 and the rotating plate 2 3 to rotate relative to each other.

[0044] The utility model is used as follows during normal use: when the two pipe bodies 1 need to be connected to each other, the handle 15 is turned to drive the handle 15 to drive the adjusting block 12 to start rotating. At the same time, since the adjusting block 12 and the side wall of the gasket 13 fit each other and the gasket 13 is provided with a through groove 14 for the transmission rod 9 to slide, the adjusting block 12 will drive the gasket 13 to start sliding, and at the same time, the protrusions 16 on the adjusting block 12 and the gasket 13 are driven to separate from each other. At this time, the connecting piece 10 and the fixing plate 2 8 are separated from each other, and at the same time, the fixing plate 1 7 and the fixing plate 2 8 lose the restriction of the connecting piece 10, driving the fixing plate 1 7 and the fixing plate 2 8 to cancel the abutment. , and then drives the fixed plate 2 8 to start rotating, and at the same time, the fixed plate 2 8 drives the transmission rod 9 to start moving along the side wall of the limiting groove 11 and disengage from the limiting groove 11, at this time, the transmission rod 9 drives the connecting piece 10 to start moving in the same direction, and drives the connecting piece 10 and the side wall of the fixed plate 7 to separate from each other, at this time, the fixed plate 17 loses its restriction, and can drive the rotating plate 1 2 to start rotating, and then rotates the rotating plate 1 2 to drive the rotating plate 1 2 and the rotating plate 2 3 to separate from each other, and then inserts the positioning block 4 on the inner side wall of the rotating plate 2 3 into the positioning groove 5 on the outer side wall of the two pipe bodies 1, and at the same time drives the rotating plate 2 3 and the side walls of the two pipe bodies 1 to fit each other.

[0045] After the second rotating plate 3 and the two pipe bodies 1 are mutually attached, the first rotating plate 2 is driven to start rotating and return to its original position. At the same time, the positioning block 4 on the inner side wall of the first rotating plate 2 is inserted into the positioning groove 5 on the outer side walls of the two pipes. At this time, the handle 15 is rotated again to drive the handle 15 back to its original position. At the same time, the handle 15 drives the adjusting block 12 to start rotating. At this time, the gasket 13 starts to move under the influence of the adjusting block 12, and drives the adjusting block 12 to come into contact with the convex block 16. At the same time, the connecting piece 10 is driven to abut against the second fixing plate 8. At this time, the second fixing plate 8 is subjected to the pressure applied by the connecting piece 10, causing the first fixing plate 7 and the second fixing plate 8 to abut against each other. Subsequently, the first rotating plate 2 is rotated back to its original position. Then, the second fixing plate 8 is driven back to its original position, and at the same time, the transmission rod 9 is driven into the limiting groove 11. At this time, the transmission rod 9 drives the connecting piece 10 to start moving in the same direction, and drives the connecting piece 10 to come into contact with the side wall of the first fixing plate 7. Then, the driving member is started to drive the first fixing plate 7 and the second fixing plate 8 to abut against each other, so as to achieve the effect of installing the two pipes without connecting the hexagon bolts to the hexagon nuts one by one, reducing the operation steps during installation, improving work efficiency. At the same time, through the setting of the rubber layer 6, the sealing effect between the first rotating plate 2, the second rotating plate 3 and the two pipe bodies 1 can be improved, and the situation of water leakage of the pipe can be avoided.
