Description

Technical Field

[0001] The utility model relates to the technical field of half joints, and more particularly to an anti-slip half joint. Background Art

[0002] The half joint is a pipeline leak stopper. The half joint and the socket half joint are pipeline emergency repair devices. The socket half joint is a device for emergency repair of water leakage at the socket where two pipes are connected. The half joint is a device for emergency repair of parts other than the socket. The device has a simple structure consisting of only two main bodies and two rubber pads. It is easy to install. Just align the two main bodies at the leaking place and tighten the nuts to complete the emergency repair of the pipeline. Using this device can save water outage time and reduce emergency repair costs.

[0003] However, when connecting existing half joints, most of them are fixed by tightening bolts. This fixing method is relatively simple, and relative displacement between the half joint and the pipeline is prone to occur. In severe cases, slippage may occur, thereby affecting the leak-proof effect of the half joint.

[0004] In addition, during the use of the existing half joint, the water spraying part is sealed by the cooperation of the first sealing gasket and the bolt. However, the first sealing gasket will age during long-term use, which requires replacement of the first sealing gasket. Most of the first sealing gaskets on the market do not have the effect of replacing the first sealing gasket. Utility Model Content
