Background
Municipal administration water supply and drainage pipe is rainwater and sewage pipeline under the town road, generally called municipal administration water supply and drainage pipe in the engineering, along with social development and drainage engineering's vigorous development, municipal administration water supply and drainage pipe's application has been more and more, general municipal administration water supply and drainage pipe all needs the connecting piece to connect the installation between the water supply and drainage pipe of both ends, but current municipal administration water supply and drainage pipe connects through welding flange on water supply and drainage pipe, then through two ring flange butt joint installations, welded technical requirement is higher, and certain space may exist when the installation, cause the pipeline to leak, increase municipal administration water supply and drainage pipe later stage's maintenance cost for this reason, we propose a novel water supply and drainage pipe connecting device.
Disclosure of Invention
An object of the utility model is to provide a novel plumbing pipe connection device to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel water supply and drainage pipe connection device, includes two sets of locking device, locking device includes two sets of arc pieces, and two sets of arc piece inboard relative settings, and is two sets of the connecting block has all been welded to both sides around the arc piece, and is two sets of from top to bottom pass through bolted connection between the connecting block, and is two sets of locking device top and bottom all are provided with fixed block, right side the welding of fixed block left side has external screw thread pole, left side the left side activity of fixed block is pegged graft have with external screw thread pole assorted female thread sleeve pipe, female thread sleeve pipe and external screw thread pole spiro union, the external screw thread pole outer wall is provided with the annular block through the connecting link, the.
Furthermore, the cross section of the internal thread sleeve is T-shaped, and a cross-shaped groove is formed in the left side of the internal thread sleeve.
Further, the inner side of the arc-shaped block is provided with a clamping groove, and a rubber pad is arranged in the clamping groove.
Furthermore, sealing gaskets are arranged at the bottoms of the annular grooves.
Further, the length of the connecting chain is equal to one half of the distance between the two sets of externally threaded rods.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, it is fast to water supply and drainage pipe connection speed, when connecting, install two sets of water supply and drainage pipe outer walls that need connect respectively with two sets of locking device, and lock, then in inserting the ring channel with the one end that water supply and drainage pipe need connect, rotate the internal thread sleeve pipe through the instrument afterwards, it is taut with two sets of locking device with the cooperation of outer screw rod to make the internal thread sleeve pipe, thereby the one end that makes two sets of water supply and drainage pipe connections tightens up with the ring channel tank bottom, install sealed the pad at the ring channel tank bottom, can improve the waterproof sealing performance between annular piece and the water supply and drainage pipe, thereby improve water supply and drainage pipe connecting device.

Detailed Description
The core of the utility model is to provide a novel water supply and drainage pipe connecting device.
The present invention will be further explained with reference to the accompanying drawings:
the utility model provides a novel water supply and drainage pipe connection device, as shown in fig. 1~3, including two sets of locking device 1, locking device 1 includes two sets of arc pieces 11, and 11 inboard relative settings in two sets of arc pieces, connecting block 12 has all been welded to both sides around two sets of arc pieces 11, connect through bolt 13 between upper and lower two sets of connecting block 12, 1 top and bottom of two sets of locking device all are provided with fixed block 2, the welding of 2 left sides of right side fixed block has external screw thread pole 3, the left side activity of left side fixed block 2 is pegged graft have with 3 assorted internal thread sleeve pipes 4 of external screw thread pole, internal thread sleeve pipe 4 and 3 spiro unions of external screw thread pole, 3 outer walls of external screw thread pole are provided with annular block 6 through connecting link 5.
As shown in fig. 1, the cross section of the internal thread sleeve 4 is T-shaped, a cross-shaped groove is formed in the left side of the internal thread sleeve 4, so that the internal thread sleeve 4 can be conveniently rotated, the internal thread sleeve 4 is matched with the external screw rod 3 to tighten the two groups of locking devices 1, and the joint of the two groups of water supply and drainage pipelines is tightened with the annular block 6;
as shown in fig. 2, a clamping groove 8 is formed in the inner side of the arc-shaped block 11, a rubber pad 9 is arranged in the clamping groove 8, so that the friction force between the locking device 1 and the water supply and drainage pipeline is increased, and the locking device 1 and the water supply and drainage pipeline are prevented from sliding;
as shown in fig. 3, the bottom of the annular groove 7 is provided with a sealing gasket, which can improve the sealing and waterproof performance between the annular block 6 and the water supply and drainage pipeline, thereby improving the overall water leakage prevention performance of the water supply and drainage pipeline connecting device;
as shown in figure 1, the length of the connecting chain 5 is equal to one half of the distance between the two groups of external thread rods 3, so that the annular block 8 can be conveniently inserted and connected with the two groups of water supply and drainage pipelines to be connected.
When in connection, the two groups of locking devices 1 are respectively arranged on the outer walls of the two groups of water supply and drainage pipelines to be connected and are locked, then one ends of the water supply and drainage pipelines to be connected are inserted into the annular groove 7, and then the internal thread sleeve 4 is rotated by a tool, so that the internal thread sleeve 4 is matched with the external screw rod 3 to tighten the two groups of locking devices 1, and the connected ends of the two groups of water supply and drainage pipelines are tightly clamped with the bottom of the annular groove 9.
