Corrugated pipe connecting head and corrugated pipe connecting structure having the same

technical field

The utility model relates to the technical field of pipeline connection, in particular to a corrugated pipe connection head and a corrugated pipe connection structure thereof.

Background technique

There is often a movable sunroof on the top of the car. Generally, the car sunroof is not easy to leak water, but as the use time becomes longer and the sealing strip of the car sunroof ages, the car sunroof is prone to water leakage. In order to reduce the water leakage of the sunroof of the car, a water receiving groove is arranged around the sunroof of the car, so that the accumulated water is not easy to leak into the interior of the car. Drainage holes are often provided in the sink, and a sunroof drain outlet is installed in the drain hole. The sunroof drain outlet is connected with a single-wall corrugated pipe, and the single-wall corrugated pipe discharges the rainwater in the sink to the outside of the vehicle. The existing single-wall corrugated pipe is directly sleeved on the outside of the sunroof drainage outlet. In this connection, the single-wall corrugated pipe is easy to be vibrated and fall off during the driving process of the car, which leads to the failure of the sunroof drainage and causes water to penetrate into the interior.

The existing patent document with the publication number of CN204750047U discloses a connection structure between an automobile sunroof and a drain pipe. Referring to FIG. 1 , it includes a skylight drainage outlet 1 and a single-wall corrugated pipe 2 in a tubular structure. The single-wall corrugated pipe 1 includes a first section and a second section that are integrally connected, and the diameter of the first section is larger than the diameter of the second section. The skylight drainage outlet 1 is set inside the first section of the single-wall corrugated pipe 2, and the outer wall of the end of the skylight drainage outlet 1 is provided with a conical barb 11, and the maximum outer diameter of the barb 11 is larger than the first The inner diameter of the segment. In this prior art, barbs 11 are provided at the end of the skylight drainage outlet, and the barbs 11 are clamped inside the single-wall corrugated pipe 2 to form a tight connection, which can solve the problem of the existing single-wall corrugated pipe 2 and the skylight drainage outlet 1 . The problem that the connection is easy to fall off.

The prior art solution in the above has the following defects: the single-wall corrugated pipe 2 is directly sleeved on the outside of the skylight drainage outlet 1, and when the first section of the single-wall corrugated pipe 2 is damaged, the entire single-wall corrugated pipe 2 is scrapped. .

In a preferred example of the present invention, it can be further configured that: the other end of the water passage pipe is used for plugging and matching with the drain outlet of the skylight.

By adopting the above technical solution, the barbs of the sunroof drain outlet are clamped inside the water conduit in a plug-fit manner to form a firm connection, and the installation of the sunroof drain outlet and the water conduit is faster.

The second purpose of the present utility model is achieved through the following technical solutions:

A corrugated pipe connection structure includes a single-wall corrugated pipe and the above-mentioned corrugated pipe connection head, and the corrugated pipe connection head is inserted and matched with the single-wall corrugated pipe.

By adopting the above technical solution, the single-wall corrugated pipe is adapted to the corrugated pipe connection head, so that the connection between the single-wall corrugated pipe and the corrugated pipe connection head is not easy to leak water.

In a preferred example of the present invention, it can be further configured that: the annular groove includes the inner wall of the casing and the outer wall of the water pipe, and the single-wall corrugated pipe is an interference fit with the inner wall of the casing and/or the outer wall of the water pipe .

By adopting the above technical solution, the single-wall corrugated pipe is in an interference fit with the inner wall of the casing and/or the outer wall of the water pipe, so the single-wall corrugated pipe abuts against the casing or the water pipe, so that the single-wall corrugated pipe and the corrugated pipe are connected. The connection between them is not easy to leak.

To sum up, the present utility model includes at least one of the following beneficial technical effects:

When a section of the single-wall corrugated pipe is damaged, since the drain outlet of the skylight and the single-wall corrugated pipe are connected by a corrugated pipe connector, it is only necessary to cut off the damaged single-wall corrugated pipe, and the single-wall corrugated pipe can still be used. It is convenient to connect with the drain outlet of the skylight, and it is not easy to scrap the whole root;

The single-wall corrugated pipe is adapted to the corrugated pipe connector, so that the connection between the single-wall corrugated pipe and the corrugated pipe connector is not easy to leak;

The groove wall of the annular groove is provided with a friction resistance structure for fixing the single-wall corrugated pipe, which can reduce the gap between the single-wall corrugated pipe and the casing. Therefore, the single-wall corrugated pipe is sleeved between the water pipe and the casing. Over time, the friction between the single-wall corrugated pipe, the casing and the water pipe increases, so the single-wall corrugated pipe is not easy to separate from the corrugated pipe connector.
