Abstract

The utility model discloses a water gauge expansion joint pipe, including connecting, be provided with lock nut on the joint, the last flexible pipe that is provided with of lock nut, flexible pipe opposite side are provided with coupling nut, and the both sides of flexible pipe all are provided with the spacing collar, and lock nut and coupling nut all are provided with towards flexible pipe one side with spacing collar complex annular ring, lie in on the flexible pipe that lock nut one side cover is equipped with the sealing washer, and the sealing washer includes a body coupling's three-layer outer lane. The utility model has the advantages of it is following and effect: after the locking nut is fixed on the connector, the three layers of outer rings are embedded into the inner ring groove and are compressed, so that leakage can be avoided, and connection stability is guaranteed. And because the inclined plane exists, can make things convenient for the outer lane to get into in the inner ring groove when adjacent sealing washer is compressed, guarantee sealed stability.

Description

Water meter telescopic connecting pipe
Technical Field
The utility model relates to a body technical field, in particular to flexible takeover of water gauge.
Background
The traditional water meter is installed by connecting common connecting pipe nuts at two ends of the water meter with a valve or a pipeline, and when the water meter is installed, particularly when a tap water company replaces an old meter, the new meter cannot be connected with water pipes at two sides due to different sizes and lengths of the new meter and the old meter. The forced installation often causes the joint to leak, and the joint or the nut can be seriously broken.
The problem that the size and the length of a new water meter are inconsistent can be solved through the water meter telescopic connecting pipe in the prior art, but the water meter telescopic connecting pipe still has defects in the actual use process, and the problem of leakage cannot be effectively solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can effectively avoid the flexible takeover of water gauge of seepage.
The above technical purpose of the present invention can be achieved by the following technical solutions: the water meter telescopic connecting pipe comprises a joint, wherein a locking nut is arranged on the joint, a telescopic pipe is arranged on the locking nut, a connecting nut is arranged on the other side of the telescopic pipe, limiting rings are arranged on two sides of the telescopic pipe, the locking nut and the connecting nut are provided with annular rings matched with the limiting rings towards one side of the telescopic pipe, a sealing ring is sleeved on one side of the telescopic pipe, which is located on the locking nut, and the sealing ring comprises three layers of outer rings which are integrally connected.
Further setting the following steps: an inner ring groove is arranged on the inner wall of the locking nut, and the outer side of the inner ring groove is flush with the inner side of the annular ring.
Further setting the following steps: the outer ring comprises an inclined plane, and the inclined plane is arranged towards the joint direction.
To sum up, the utility model discloses following beneficial effect has: after the locking nut is fixed on the connector, the three layers of outer rings are embedded into the inner ring groove and are compressed, so that leakage can be avoided, and connection stability is guaranteed. And because the inclined plane exists, can make things convenient for the outer lane to get into in the inner ring groove when adjacent sealing washer is compressed, guarantee sealed stability.
Drawings
FIG. 1 is a schematic structural view of a water meter telescopic connection pipe;
fig. 2 is an enlarged view of a point a in fig. 1.
In the figure: 1. a joint; 2. locking the nut; 21. an annular ring; 22. an inner ring groove; 3. a telescopic pipe; 31. a limiting ring; 4. a connecting nut; 5. a seal ring; 51. an outer ring; 511. a bevel.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The water meter telescopic connecting pipe comprises a connector 1, wherein the connector 1 is provided with a regular hexagonal block, both ends of the regular hexagonal block are provided with external threads, and the inner side of the connector 1 is provided with a through round hole.
A locking nut 2 is fixed on the joint 1 through external threads, an expansion pipe 3 is arranged on the locking nut 2, and a connecting nut 4 is arranged on the other side of the expansion pipe 3.
Wherein, the both ends of flexible pipe 3 all are provided with spacing collar 31, and lock nut 2 and coupling nut 4 all are provided with annular ring 21 towards flexible pipe 3 one side, and the cooperation of annular ring 21 and spacing collar 31 can avoid lock nut 2 and coupling nut 4 to break away from flexible pipe 3.
One side of the telescopic pipe 3, which is positioned on the locking nut 2, is sleeved with a sealing ring 5, the sealing ring 5 comprises three layers of outer rings 51, and the outer rings 51 are integrally connected. An inner ring groove 22 is arranged on the inner wall of the locking nut 2 adjacent to the annular ring 21, and the outward inner wall of the inner ring groove 22 is flush with the inward inner wall of the annular groove. After the locking nut 2 is fixed on the joint 1, the three layers of outer rings 51 are embedded into the inner ring groove 22 and are compressed, so that leakage can be avoided, and connection stability is guaranteed.
The outer ring 51 is provided with an inclined plane 511, the thickness of the inclined plane 511 is reduced from inside to outside, the inclined plane 511 faces the direction of the joint 1, and when the sealing ring 5 is compressed, the outer ring 51 enters the inner ring groove 22, so that the sealing stability is ensured.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
