Description

Technical Field

[0001] The utility model relates to the technical field of building municipal drainage, in particular to a drainage pipe which is convenient for docking. Background Art

[0002] Drain pipes in building municipal drainage systems refer to pipe systems used to discharge rainwater, wastewater or other liquids. These drain pipes are usually made of durable materials such as PVC, HDPE, cast iron or concrete. The types and uses of drain pipes can vary depending on specific drainage needs and environmental conditions.

[0003] Existing cast iron drain pipes are fixed by flanges when they are butt-jointed. However, during the actual installation, personnel are required to fix the mounting holes between the flanges with bolts. The drain pipes need to be stabilized during installation. During the installation, accidental touch may cause the mounting holes between the flanges to shift, thus affecting their normal butt-joint installation. Utility Model Content

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a drain pipe that is easy to connect, including a drain pipe 1, a flange 2 fixed on the surface of the drain pipe 1, a drain pipe 3 is arranged at the right end of the drain pipe 1, a flange 2 4 is fixed on the surface of the drain pipe 2 3, and a stabilizing component 5 and a releasing component 6 are arranged on the surfaces of the flange 1 2 and the flange 2 4. The stabilizing component 5 includes: a U-shaped rod 50, a positioning hole 1 51, a fixing plate 52, a circular ring 53, a volute spring 54, a resistance groove 55, a limiting groove 56, a positioning hole 2 57, and a cavity 58.

[0023] The U-shaped rod 50 is fixed on the surface of the flange 24, and a positioning hole 51 is provided on the surface of the flange 2. A fixing plate 52 is fixed on the side of the flange 2 away from the flange 24, and the fixing plate 52 is penetrated by the drain pipe 1. A cavity 58 is provided inside the fixing plate 52, and the inner wall of the cavity 58 is rotatably connected to the ring 53. A volute spring 54 is fixed on the surface of the ring 53, and one end of the volute spring 54 away from the ring 53 is fixed on the inner wall of the cavity 58. A resistance groove 55 is provided on the side of the ring 53 close to the U-shaped rod 50, and a limiting groove 56 is provided on the ring 53. The ring 53 close to the A second positioning hole 57 is provided on one side of the U-shaped rod 50. When the flange 1 2 and the flange 2 4 are moved closer together, the U-shaped rod 50 enters the first positioning hole 51 and the second positioning hole 57. The surface of the U-shaped rod 50 contacts the inclined surface of the contact groove 55, the ring 53 rotates, and the spiral spring 54 is rolled up. When the surfaces of the flange 1 2 and the flange 2 4 are tightly fitted, the U-shaped rod 50 is located at the junction of the contact groove 55 and the limiting groove 56, the spiral spring 54 is released, the ring 53 reverses, the U-shaped rod 50 is located in the limiting groove 56, and the inner wall of the limiting groove 56 contacts the surface of the U-shaped rod 50, thereby limiting the position.

[0024] The releasing component 6 includes a connecting groove 60, which is arranged on the side of the circular ring 53 away from the interference groove 55. A spring 61 is fixed to the side of the fixed plate 52 away from the flange 1 2. A pressing ring 62 is fixed to the end of the spring 61 away from the fixed plate 52. A contact plate 63 is fixed to the surface of the pressing ring 62. The end of the contact plate 63 away from the pressing ring 62 passes through the fixed plate 52, pressing the pressing ring 62, and the contact plate 63 contacts the inclined surface of the connecting groove 60. At this time, the circular ring 53 rotates again. At this time, the U-shaped rod 50 is again located at the junction of the limiting groove 56 and the interference groove 55. At this time, personnel can separate flange 1 2 and flange 2 4.

[0025] The interference groove 55 is set to be an inclined surface. When it is interfered, the ring 53 can be rotated. The limit groove 56 is interconnected with the interference groove 55, and the U-shaped rod 50 can move normally. The connecting groove 60 is set to be an inclined surface, and the inclined surface of the connecting groove 60 is opposite to the interference groove 55. When the connecting groove 60 is interfered, the ring 53 can be driven to rotate. The shapes of the positioning hole 1 51 and the positioning hole 2 57 are consistent with the width of the U-shaped rod 50, which is convenient for the U-shaped rod 50 to enter.

[0026] When it is necessary to dock and install the drain pipe 1 and the drain pipe 2, the flange 1 and the flange 2 can be moved closer to each other so that the U-shaped rod 50 enters the positioning hole 1 and the positioning hole 2, and the surface of the U-shaped rod 50 contacts the inclined surface of the contact groove 55, driving the ring 53 to rotate, and the volute spring 54 is wound. When the surfaces of the flange 1 and the flange 2 are tightly fitted, the U-shaped rod 50 is located at the junction of the contact groove 55 and the limiting groove 56. At this time, the volute spring 54 is released, driving the ring 53 to reverse, so that the U-shaped rod 50 is located in the limiting groove 56. The wall contacts the surface of the U-shaped rod 50, and then limits the position, stabilizes flange 1 2 and flange 2 4, and does not cause accidental contact, which causes the mounting hole between flange 1 2 and flange 2 4 to be offset and affect the installation. At this time, it can be fixed by bolts. When separation is required, the pressure ring 62 is pressed, and the contact plate 63 contacts the inclined surface of the connecting groove 60. At this time, the ring 53 rotates again. At this time, the U-shaped rod 50 is again located at the junction of the limiting groove 56 and the contact groove 55. At this time, personnel can separate flange 1 2 and flange 2 4. When the pressure ring 62 is released, the spring 61 drives the pressure ring 62 to reset, and the spiral spring 54 drives the ring 53 to reset.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
