Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, and in particular to a drainage pipe that is easy to install. Background Technology

[0002] Drainage pipelines refer to the system of pipes and channels that collect and discharge sewage, wastewater and rainwater, as well as their ancillary facilities. This includes main pipes, branch pipes and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, any pipe that serves a drainage function should be counted as a drainage pipeline.

[0003] Chinese Patent Publication No. CN217519416U discloses a connection structure for water supply and drainage pipes, relating to the technical field of drainage pipes. It includes an installation disc with installation pipes on both sides for mounting water supply and drainage pipes. Multiple arc-shaped pressure plates are located on both sides of the installation disc, distributed evenly along its circumference, and used to press against the outer wall of the drainage pipes. This connection structure enables the connection of the drainage pipes. Therefore, during transportation, the drainage pipes can be disassembled for transport and reassembled on-site, reducing the space occupied during transport and facilitating convenient transportation.

[0004] The above-mentioned technology achieves the fixation of the drainage pipe by pressing the outer wall of the drainage pipe with a pressure plate. During installation, multiple handwheels need to be tightened so that the screw can push the pressure plate to fully press the drainage pipe. The steps are complicated and the operation is cumbersome. Moreover, it is difficult to solve the leakage problem caused by the deformation of the drainage pipe. Therefore, this utility model discloses a drainage pipe that is easy to install to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage pipe that is easy to install, so as to solve the problems of low installation efficiency and poor sealing of traditional drainage pipes mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems:

[0007] A drainage pipe that is easy to install includes a pipe body, with a female connector and a male connector respectively provided at both ends of the pipe body. A receiving groove is provided on the end face of the female connector away from the pipe body, and a sliding sleeve is slidably embedded in the receiving groove. A locking component for limiting the position of the sliding sleeve is installed on the outer wall of the female connector.

[0008] The sliding sleeve has multiple hook grooves equidistantly arranged on the side end face away from the receiving groove. The inner wall of the hook groove facing the opposite direction to the end face of the sliding sleeve has a first inclined surface. The sub-connector has a slot on the side end face away from the main pipe body. Multiple connecting columns are fixed between the inner walls of the two sides of the slot.

[0009] As a further embodiment of this utility model, the locking assembly includes a recessed frame fixed to the outer wall of the female connector. Sliding grooves are provided on both inner walls of the recessed frame. A long bolt is threadedly connected to the middle of the recessed frame. A locking block is rotatably connected to one end of the long bolt. A slider is provided on both sides of the locking block. The slider is slidably connected to the adjacent sliding groove. A second inclined surface is provided on the side wall of the locking block away from the long bolt.

[0010] As a further embodiment of this utility model, the locking assembly further includes a locking rod fixed to the outer wall of one side of the sliding sleeve and a right-angled groove formed on the outer peripheral wall of the receiving groove. The end of the locking rod away from the sliding sleeve extends out of the right-angled groove, and the locking rod is in contact with the second inclined surface.

[0011] As a further embodiment of this utility model, the diameter of the locking rod is the same as the width of the right-angle groove, one side groove of the right-angle groove is perpendicular to the moving path of the sliding sleeve, and the other side groove of the right-angle groove is parallel to the moving path of the sliding sleeve.

[0012] As a further embodiment of this invention, the length of the sliding sleeve is less than the depth of the receiving groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model provides a conveniently installed drainage pipe. The locking block can slide linearly by rotating the long bolt. The second inclined surface on the locking block presses against the locking rod, which drives the sliding sleeve to rotate synchronously. Meanwhile, the first inclined surface on the sliding sleeve continuously presses against the connecting column, which can push the sub-connector to move in the opposite direction and press against the female connector. This ensures that the sealing gasket between the sub-connector and the female connector is fully compressed, guaranteeing the sealing performance. Moreover, the above operation only requires tightening the long bolt, simplifying the operation steps and improving the connection efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-6 This utility model provides a drainage pipe that is easy to install, including a pipe body 1, and a female connector 2 and a male connector 3 are respectively provided at both ends of the pipe body 1.

[0025] Specifically, a sealing gasket is provided between the opposite sides of the male connector 2 and the female connector 3. The sealing gasket is annular and made of rubber material. When the sealing gasket is squeezed, it will deform to a large extent, which can fill the gap between the male connector 2 and the female connector 3 and prevent leakage. It is worth noting that protrusions and grooves can be provided on the opposite sides of the male connector 2 and the female connector 3 respectively. After the protrusions and grooves are aligned and inserted, the angle of the male connector 2 and the female connector 3 can be prevented from changing. On the other hand, the sealing gasket should be provided with an insertion structure that matches the protrusions or grooves.

[0026] Furthermore, a receiving groove 31 is provided on the end face of the female connector 3 away from the main pipe body 1, and a sliding sleeve 32 is slidably embedded in the receiving groove 31. A plurality of hook grooves 321 are provided at equal intervals on the end face of the sliding sleeve 32 away from the receiving groove 31. A first inclined surface 322 is provided on the inner wall of the hook groove 321 facing the opposite side of the end face of the sliding sleeve 32. A slot 21 is provided on the end face of the female connector 2 away from the main pipe body 1, and a plurality of connecting posts 22 are fixed between the inner walls of the two sides of the slot 21.

[0027] Specifically, the connecting post 22 moves within the hook groove 321 of the sliding sleeve 32, and is pushed to move in the opposite direction by the compression of the first inclined surface 322, ensuring sealing. The combination of multiple connecting posts 22 and hook grooves 321 at equal intervals ensures the uniformity and stability of the connection and prevents local leakage.

[0028] Specifically, due to the presence of the first inclined surface 322, the axial force of the sliding sleeve 32 is converted into a radial force on the sub-connector 2. The magnitude of this radial force can be calculated according to the principle of force decomposition. Under different pressures, this radial force can ensure that the sub-connector 2 exerts sufficient pressure on the sealing gasket, causing the sealing gasket to deform, thereby achieving a good sealing effect. Furthermore, the equidistant arrangement of multiple connecting posts 22 and hook grooves 321 ensures the uniformity and stability of the connection. Under internal pressure, the force at the connection point between the sub-connector 2 and the female connector 3 will not deviate, preventing localized leakage.

[0029] Furthermore, the length of the sliding sleeve 32 is less than the depth of the receiving groove 31;

[0030] Specifically, the sliding sleeve 32 can be completely housed within the receiving groove 31. When connecting adjacent drainage pipes, the drainage pipes can be directly aligned front to back without needing to be misaligned during connection. This design is particularly suitable for larger drainage pipes or in environments with limited construction space. For example, when connecting adjacent drainage pipes, they can be directly aligned front to back without needing to be misaligned during connection. This design greatly improves installation efficiency. Compared to the traditional misaligned connection method, it saves installation time and avoids the risk of component damage that may result from misaligned connection. It is especially suitable for larger drainage pipes or in environments with limited construction space. In confined spaces, operators can operate more conveniently, reducing construction difficulty.

[0031] Furthermore, a locking assembly 4 for limiting the position of the sliding sleeve 32 is installed on the outer wall of the female connector 3. The locking assembly 4 includes a concave frame 41 fixed to the outer wall of the female connector 3. Sliding grooves 411 are provided on both inner walls of the concave frame 41. A long bolt 42 is threadedly connected to the middle of the concave frame 41. A locking block 43 is rotatably connected to one end of the long bolt 42. A slider 431 is provided on both sides of the locking block 43. The sliders 431 are slidably connected to the adjacent sliding grooves 411. A second inclined surface 432 is provided on the side wall of the locking block 43 away from the long bolt 42.

[0032] Specifically, the threaded connection design allows the rotation of the long bolt 42 to be converted into linear motion, thereby achieving precise control over the position of the locking block 43. The slider 431 is designed to cooperate with the groove 411 in the recessed frame 41 to ensure the linearity and stability of the locking block 43 during movement. It is worth noting that the threaded connection has a one-way self-locking function, which allows the stress of the locking rod 44 to act on the locking block 43, while the position of the locking block 43 remains unchanged, thereby preventing sealing leakage.

[0033] Furthermore, the locking assembly 4 also includes a locking rod 44 fixed to one side of the outer wall of the sliding sleeve 32 and a right-angle groove 45 opened on the outer peripheral wall of the receiving groove 31. The end of the locking rod 44 away from the sliding sleeve 32 passes through the right-angle groove 45, and the locking rod 44 is in contact with the second inclined surface 432.

[0034] Specifically, the movement of the locking block 43 directly affects the position and state of the locking rod 44. When the locking block 43 slides linearly due to the rotation of the long bolt 42, its second ramp surface 432 will press against the locking rod 44. This pressing action causes the locking rod 44 to drive the sliding sleeve 32 to rotate synchronously. At the same time, the first ramp surface 322 on the sliding sleeve 32 will continuously press against the connecting post 22, pushing the sub-connector 2 to move in the opposite direction and press against the female connector 3, ensuring that the sealing gasket between the sub-connector 2 and the female connector 3 is fully compressed, thereby ensuring the sealing performance.

[0035] Furthermore, the diameter of the locking rod 44 is the same as the width of the right-angle groove 45, one side groove of the right-angle groove 45 is perpendicular to the moving path of the sliding sleeve 32, and the other side groove of the right-angle groove 45 is parallel to the moving path of the sliding sleeve 32.

[0036] Specifically, during installation, pushing the locking rod 44 along the side groove perpendicular to the movement path of the sliding sleeve 32 facilitates the insertion of the sliding sleeve 32 into the slot 21 of the sub-connector 2. When the locking rod 44 reaches the corner of the right-angle groove 45, the connecting post 22 extends into the corner of the hook groove 321. Continuing to push the locking rod 44 into the side groove parallel to the movement path of the sliding sleeve 32 causes the connecting post 22 to embed deeply into the hook groove 321, thereby locking the sliding sleeve 32 and the sub-connector 2.

[0037] Working principle: In use, first align the front and rear drainage pipes, push the locking rod 44 so that the sliding sleeve 32 is embedded in the slot 21. After the locking rod 44 reaches the corner of the right angle groove 45, the connecting post 22 extends into the corner of the hook groove 321. Then push the locking rod 44 into the other side groove of the right angle groove 45, which can drive the connecting post 22 to be embedded deep into the hook groove 321. After that, rotate the long bolt 42 to push the locking block 43 to slide in a straight line, so that the second slope surface 432 on the locking block 43 squeezes the locking rod 44. The locking rod 44 drives the sliding sleeve 32 to rotate synchronously. The first slope surface 322 continues to squeeze the connecting post 22, which can push the sub-connector 2 to move in the opposite direction to squeeze the female connector 3, ensuring that the sealing gasket between the sub-connector 2 and the female connector 3 is fully squeezed, thus ensuring the sealing performance.
