The embodiments described below are exemplary and are intended to be illustrative of the present invention, but should not be construed as limiting the invention.

Example 1.

As shown in fig. 1-3, the present invention relates to a connecting structure for sewers in sink, which can be used for connecting a plurality of pipes in the sewers, in order to increase the water pressure impact resistance. In fig. 1, the sewage draining pipeline is provided with three pipeline connection positions, namely a first drainer drain pipe corresponding to a first drainer and a first pipeline connection structure 1 of a water collecting pipeline; a second drainer drain pipe corresponding to the second drainer is connected with a second pipeline connection structure 2 of the bent pipeline; and a third pipeline connection structure 3 for the bent pipeline and the water collecting pipeline.

The pipeline connection structure I, the pipeline connection structure II and the pipeline connection structure III are consistent in specific connection mode, taking the pipeline connection structure II as an example, the pipeline connection structure II comprises a first drain pipe 4, a second drain pipe 5, a sealing ring 6, a sealing gasket 7, a conical metal clamping ring 8 and a locking cover 9 provided with an internal thread, wherein the first drain pipe 4, the second drain pipe 5, the sealing ring 6, the sealing gasket 7, the conical metal clamping ring 8 and the locking cover are mutually connected and matched, the second drain pipe is provided with an external threaded part 5-1, one end of the first drain pipe is inserted into the second drain pipe, the sealing ring, the sealing gasket, the conical metal clamping ring and the locking cover are respectively sleeved at the end part of the drain pipe, and the locking cover is covered outside the sealing ring, the sealing gasket and the conical metal clamping ring and is fixedly connected with the external threaded part 5-1 of the second drain pipe through threads. In the embodiment, the conical metal snap ring 8 is provided with the internal teeth 8-1 which can be provided with a tip part or a flat head part, and the internal teeth are generally arranged to be flat heads, so that the internal teeth are prevented from being pressed into the side surface of the first drain pipe 4; when the locking cover is pressed and extruded on the conical metal snap ring, the internal teeth can only be tightly bitten on the first drain pipe, so that the locking cover is prevented from being separated from the external thread part of the second drain pipe under strong water pressure.

Further, in this embodiment, the sealing washer is the rubber circle, and sealed the pad is the plastic washer, and toper metal snap ring is annular stainless steel sheet, has certain elasticity for the locking closure is inseparabler with the combination of screw thread portion. The sealing gasket 7 is arranged between the sealing ring and the conical metal clamping ring, and when the locking cover is locked, the conical metal clamping ring is tightly attached to the sealing gasket. The conical metal snap ring is provided with a conical end which is pressed against the sealing pad, and a flared end which is pressed against the inside of the lock cover. Under the extrusion of the lock cover, the tapered metal snap ring gradually changes into a ring shape and clings to the sealing gasket.

The side part of the sealing ring is provided with an inclined surface 6-1 which is tightly attached to the end part of the second drainage pipe, so that a good sealing effect is achieved. The outer edge of the lock cover is provided with an annular convex edge 9-1, and the side part of the lock cover is provided with a plurality of convex ribs 9-2 so as to increase the friction force of rotating the lock cover.

Example 2.

In this embodiment, the tapered metal snap ring is a metal sheet in an annular conical shape, and the inner edge of the tapered metal snap ring is not provided with the internal teeth, but the tapered metal snap ring needs to be replaced every time the connection structure is disassembled.

Compared with the prior art, the utility model adopts the pipeline connection locking structure formed by introducing the sealing ring, the sealing gasket, the conical metal snap ring and the locking cover between the two rows of water pipes which are connected and matched with each other, because the conical metal snap ring has certain elasticity, under the condition that the lock cover is locked with the thread part, the lock cover can extrude the tapered metal snap ring, so that the inner edge of the tapered metal snap ring can be tightly meshed with the side surface of the first drainage pipe, and the conical metal snap ring is in surface contact with the sealing gasket, so that the friction force between the conical metal snap ring and the sealing gasket is greatly increased, the connection position between the first drainage pipe and the second drainage pipe can bear higher water pressure, even if high-pressure water flow is instantly introduced into the sewage discharge pipeline, the problem of water leakage at the connection position between the pipelines is avoided, the stability is good, according to detection, the water leakage can be generated by bearing the water pressure of 0.1MPa, and the water leakage detection device can be completely applied to a sewage discharge pipeline.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
