Abstract
Description
Technical Field
[0001] This invention relates to the field of variable joint technology, and in particular to a clamp-type variable joint structure for drainage pipes. Background Technology
[0002] Plastic inspection wells are injection-molded products with the inlet and outlet of the well base at the same elevation. However, in actual construction, the elevations of the pipes at both ends of the well base are different, and the angles of the well base are all regular angles, such as 180°, 90°, 45°, etc. But the pipe routing angles at the construction site are irregular, such as 50° or 130°. In this case, an angle reducer is needed to connect the pipes to deal with the irregular pipe routing angles. The angle reducer consists of two parts (two connector pipes) spliced together by a clamp in the middle, and has a built-in sealing ring. By loosening the clamp in the middle, one end is fixed, and the other end is rotated 360° to adjust to the required angle to change the slope and angle.
[0003] When installing an angle joint: During construction, the connection should follow the sequence of well-pipe-well, with a section of pipe extending from the well base and the well base rubber ring fitted onto the first compartment of the pipe; Unscrew the nut on the angle joint clamp so that one end can rotate; Insert one end of the angle adapter into the pipe; Rotate the other end of the angle adapter to the desired angle before inserting the pipe. If the slope to be adjusted is greater than 0.6 meters, two angle joints are generally required to adjust it to the correct position.
[0004] Issues to be improved: The two fittings of a variable angle joint can only be adjusted by rotation. Although it can adapt to different elevation angles, when there are changes in the direction of pipe laying, the variable angle joint, which can be adjusted by rotation, is not convenient to adjust the bending angle to adapt to the changes in the bending angle of pipe laying.
[0005] To address this issue, we propose a clamp-type variable joint structure for drainage pipes. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamp-type variable joint structure for drainage pipes.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A clamp-type variable joint structure for drainage pipes includes a variable angle joint, which includes a joint pipe A and a joint pipe B connected together. A variable adjustment connection structure is provided between the joint pipe A and the joint pipe B, that is, the joint pipe A and the joint pipe B are connected through the variable adjustment connection structure. The variable adjustment connection structure includes a universal connection component A and a universal connection component B. The universal connection component A includes a movable part A and an outer cover part A. The universal connection component B includes a movable part B and an outer cover part B. The movable component A includes an intermediate tube A, a flared tube A, and a spherical cup A connected together; the outer cover component A includes a cup cover A and a cup cover B connected together by a clamp B. The movable component B includes an intermediate tube B, a flared tube B, and a spherical cup B connected together, and the outer cover component B includes a cup cover C and a cup cover D connected together by a clamp D.
[0008] Preferably, the intermediate tube A is connected between the flared tube A and the spherical cup, and the flared tube A and the spherical cup are connected through the intermediate tube A. Specifically, the intermediate tube A is connected to the small-diameter end of the flared tube A, so that the intermediate tube A, the flared tube A and the spherical cup are connected into a connected whole.
[0009] Preferably, the outer ring of the cup cover B at the small diameter end has an outer ring F, the outer ring of the cup cover B at the large diameter end has an outer ring G, and the outer ring of the cup cover A at the large diameter end has an outer ring E. Outer ring E and outer ring G are of the same specification and are connected together by a clamp B. When cup cover A and cup cover B need to be combined and connected, cup cover A and cup cover B are brought close together so that the outer rings E and G face to face. Then, the clamp B is used to hold and lock the outer rings E and G. Specifically, the clamp B is fitted over the outer rings E and G and bolted in place. This connects cup cover A and cup cover B together to form a spherical cover A that can accommodate a spherical cup. The outer surface of the spherical cup or the inner wall of the spherical cover A is provided with a rubber layer to ensure a seal between the two without hindering movement. It should be noted that when the spherical cup is located in the spherical cover A, the intermediate tube is located in the small-diameter end of the cup cover A, and the diameter of the intermediate tube is smaller than the diameter of the small-diameter end of the cup cover A. This design is to facilitate the movement of the spherical cup in the spherical cover A. The range of motion is within the range of the small-diameter end diameter of the cup cover A. Because it is a movable flared tube A, the flared tube A drives the spherical cup to move in the spherical cover A through the intermediate tube. This movement can adjust the position of the flared tube A relative to the spherical cover A, thereby changing the position of the flared tube A to facilitate connection with the inclined pipe.
[0010] Preferably, the intermediate tube B, the flared tube B, and the spherical cup B are connected as a single, interconnected unit. The intermediate tube B is connected between the flared tube B and the spherical cup B, and is located at the smaller diameter end of the flared tube B.
[0011] Preferably, the cup cover C has an outer ring H at the large-diameter end, and the cup cover D has an outer ring I and an outer ring J at each end. The outer ring I is located near the small-diameter end of the cup cover D, and the outer ring J is located near the large-diameter end of the cup cover D. The outer ring J and outer ring H are of the same specification and are connected by a clamp D. When it is necessary to connect the cup cover C and the cup cover D together, the cup cover C and the cup cover D are brought close together so that the outer ring J and the outer ring H are pressed together. Then, the clamp D is put on the outside of the outer ring J and the outer ring H, and the clamp D is tightened with bolts. This causes the outer ring J and outer ring H to fit tightly together, thereby connecting the cup cover C and cup cover D together to form a spherical cover B that can accommodate the spherical cup B. There is sealing rubber between the spherical cup B and the spherical cover B to improve the sealing performance. The diameter of the intermediate tube B is smaller than the diameter of the small diameter end of the cup cover C, so as to provide a range of motion for the intermediate tube B, so that the spherical cup B can move in the spherical cover B. This makes it easy to adjust the angle of the flared tube B relative to the spherical cover B, and can adjust the flared tube B to be on a different center line from the spherical cover B, which makes it easy to connect the flared tube B to an inclined pipe.
[0012] Preferably, the outer ring F and the outer ring I have the same specifications, and the outer ring F and the outer ring I are connected by a clamp C. The cup cover B and the cup cover D are connected together with the cooperation of the outer ring F, the outer ring I and the clamp C. When it is necessary to connect the cup cover B and the cup cover D, the outer ring F and the outer ring I on the cup cover B and the cup cover D are brought close together, so that the opposite surfaces of the outer ring F and the outer ring I are pressed together. Then the clamp C is put on the outer ring F and the outer ring I and the clamp C is locked with bolts, so that the outer ring F and the outer ring I are tightly bound together, and thus the cup cover B and the cup cover D are connected into a detachable whole.
[0013] Preferably, one end of the flared tube A has an outer ring C, which is connected to the large-diameter end of the flared tube A. One end of the connector tube A has an outer ring A, and the specifications of the outer ring A are the same as those of the outer ring C. The outer ring A and the outer ring C are connected by a clamp A. When it is necessary to connect the flared tube A and the connector tube A, the connector tube A is brought close to the flared tube A, and the opposite surfaces of the outer ring A and the outer ring C are brought together. Then, the clamp A is put on the outside of the outer ring A and the outer ring C and locked with bolts, so that the outer ring A and the outer ring C are tightly bound together, thereby connecting the connector tube A and the flared tube A together.
[0014] Preferably, the outer ring D is located at the outer circumference of the large-diameter end of the flared pipe B, and the outer ring B is located at one end of the connector pipe B. The outer ring B and the outer ring D are of the same specification. The outer ring B is connected by a clamp E. When it is necessary to connect the flared pipe B and the connector pipe B, the flared pipe B and the connector pipe B are brought close together, and the opposite surfaces of the outer ring D and the outer ring B are brought close together. Then, the clamp E is put on the outside of the outer ring D and the outer ring B and locked with bolts, so that the outer ring D and the outer ring B are tightly bound together, thereby connecting the flared pipe B and the connector pipe B into a detachable whole.
[0015] Preferably, clamps A, B, C, D, and E each include two semi-annular clamps, and each of the two semi-annular clamps has a clamping groove on its inner ring surface. The clamping groove contains a rubber pad. When connected, there is a sealing ring between the two outer rings that need to be connected. The outer rings of the two outer rings are located in the clamping groove. Both ends of the two semi-annular clamps have locking blocks. The locking blocks at both ends of the two semi-annular clamps are locked together by bolts, so that the two semi-annular clamps are connected together to form a complete annular clamp, which holds the two outer rings that need to be connected together, thereby connecting and communicating the pipes that are connected to the outer rings.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention allows for adjustment of the bending angle of the variable angle joint based on the rotatable adjustment required for pipe connection, thus facilitating the bending connection of two pipes that need to be connected. This eliminates the need to replace joints with different bending angles to connect the two pipes. In addition, the variable adjustment connection structure is easy to disassemble and assemble during use, and can be used as a whole or disassembled as needed. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0024] Reference Figure 1-6A clamp-type variable joint structure for drainage pipes includes a variable angle joint, which comprises a joint pipe A1 and a joint pipe B2 connected together. A variable adjustment connection structure is provided between the joint pipes A1 and B2, meaning that the joint pipes A1 and B2 are connected through the variable adjustment connection structure. The variable adjustment connection structure includes a universal connection component A and a universal connection component B. The universal connection component A includes a movable part A3 and an outer cover A5. The universal connection component B includes a movable part B4 and an outer cover B6. The movable part A3 includes an intermediate pipe A31, a flared pipe A32, and a spherical cup A33 connected together. The outer cover A5 includes cup covers A51 and B52 connected together by a clamp B8. The movable part B4 includes an intermediate pipe B41, a flared pipe B42, and a spherical cup B43 connected together. The outer cover B6 includes cup covers C61 and D62 connected together by a clamp D10.
[0025] Reference Figure 1-6A clamp-type variable joint structure for drainage pipes, wherein the intermediate pipe A31 connects the flared pipe A32 and the spherical cup 33, and connects the flared pipe A32 and the spherical cup 33 through the intermediate pipe A31. Specifically, the intermediate pipe A31 is connected to the small-diameter end of the flared pipe A32, so that the intermediate pipe A31, the flared pipe A32 and the spherical cup 33 are connected into a continuous whole; the outer ring of the small-diameter end of the cup cover B52 has an outer ring F521, and the large-diameter end of the cup cover B52... The outer ring of the cup cover A51 has an outer ring G522 at the outer rim position, and the outer ring of the cup cover A51 at the large diameter end has an outer ring E511. The outer ring E511 and the outer ring G52 have the same specifications. The outer ring E511 and the outer ring G52 are connected together by a clamp B8. When it is necessary to put the cup cover A51 and the cup cover B52 together, bring the cup cover A51 and the cup cover B52 close together and make the outer ring E511 and the outer ring G52 face to face. Then, the outer ring E511 and the outer ring G52 are connected by the clamp B8. 2. Holding and locking: Specifically, clamp B8 is fitted over the outer rings E511 and G52 and bolted in place. This connects cup cover A51 and cup cover B52 together to form a spherical cover A that can accommodate the spherical cup 33. A rubber layer is provided on the outer surface of the spherical cup 33 or the inner wall of the spherical cover A to ensure a seal between the two without hindering movement. It should be noted that when the spherical cup 33 is located in the spherical cover A, the intermediate tube 31 is located in the smaller diameter end of cup cover A51, and the intermediate tube 3... The diameter of 1 is smaller than the small diameter end diameter of cup A51. This design is to facilitate the movement of spherical cup 33 in spherical cover A. The range of movement angle is the range of the small diameter end diameter of cup A51. Because it is a movable flared tube A32, the flared tube A32 drives the spherical cup 33 to move in spherical cover A through the intermediate tube 31. This kind of movement can adjust the position of flared tube A32 relative to spherical cover A, thereby changing the position of flared tube A32 to facilitate connection with inclined pipe.
[0026] Reference Figure 1-6A clamp-type variable joint structure for drainage pipes is disclosed. The intermediate pipe B41, flared pipe B42, and spherical cup B43 are connected as a single, interconnected unit. The intermediate pipe B41 connects between the flared pipe B42 and the spherical cup B43, and is located at the small-diameter end of the flared pipe B42. The outer ring of the cup cover C61 has an outer ring H611 at its large-diameter end. The outer rings of the cup cover D62 at both ends have outer rings I621 and J622, respectively. Outer ring I621 is located near the small-diameter end of the cup cover D62, and outer ring J622 is located near the large-diameter end of the cup cover D62. Outer ring J622 and outer ring H611 are of the same specification and are connected by a clamp D10. When it is necessary to connect cup cover C61 and cup cover D62 together, cup cover C61 and cup cover D62 are connected... D62 is brought close together so that outer ring J622 and outer ring H611 are attached together. Then, clamp D10 is placed on the outside of outer ring J622 and outer ring H611, and clamp D10 is tightened with bolts, so that outer ring J622 and outer ring H611 are tightly attached together. This connects cup cover C61 and cup cover D62 to form a spherical cover B that can accommodate spherical cup B43. There is sealing rubber between spherical cup B43 and spherical cover B to improve the sealing performance. The diameter of intermediate tube B41 is smaller than the diameter of the small diameter end of cup cover C61 to provide a range of motion for intermediate tube B41, so that spherical cup B43 can move in spherical cover B. This makes it easy to adjust the angle of flared tube B42 relative to spherical cover B, so that flared tube B42 is not on the same center line as spherical cover B, which makes it easy to connect flared tube B42 to inclined pipe.
[0027] Reference Figure 1-6 A clamp-type variable joint structure for drainage pipes is disclosed, wherein the outer ring F521 and the outer ring I621 are of the same specification and are connected by a clamp C9. The cup cover B52 and the cup cover D62 are connected together with the cooperation of the outer ring F521, the outer ring I621 and the clamp C9. When it is necessary to connect the cup cover B52 and the cup cover D62, the outer ring F521 and the outer ring I621 on the cup cover B52 and the cup cover D62 are brought close together, so that the opposite surfaces of the outer ring F521 and the outer ring I621 are pressed together. Then the clamp C9 is put on the outer ring F521 and the outer ring I621 and the clamp C9 is locked with bolts, so that the outer ring F521 and the outer ring I621 are tightly bound together, and the cup cover B52 and the cup cover D62 are connected into a detachable whole.

One end of the connector pipe A1 has an outer ring A101, with the same specifications as the outer ring C321. The outer ring A101 and outer ring C321 are connected by a clamp A7. When connecting the flared pipe A32 and the connector pipe A1, the connector pipe A1 is brought close to the flared pipe A32, so that the outer rings A101 and C321 are pressed together. Then, the clamp A7 is fitted over the outer rings A101 and C321 and tightened with bolts, thus connecting the connector pipe A1 and the flared pipe A32.

The outer ring of the large-diameter end of the flared pipe B42 has an outer ring D421, and one end of the connector pipe B2 has an outer ring B201. The outer ring B201 and the outer ring D421 are of the same specification. The outer ring B201 is connected to the connector pipe B2 via a clamp E11. When it is necessary to connect the flared pipe B42 and the connector pipe B2, the flared pipe B42 and the connector pipe B2 are brought close together, and the opposite surfaces of the outer ring D421 and the outer ring B201 are brought close together.

During connection, a sealing ring is placed between the two outer rings to be connected, and the outer rings of both outer rings are positioned within the clamping groove.
