Description

Technical Field

[0001] The utility model relates to the technical field of fiberglass pipes, in particular to a fiberglass pipe with reliable butt joint. Background Technique

[0002] The fiberglass pipe is also called a glass fiber wound sand-filled pipe, mainly using glass fiber and its products as reinforcing materials, unsaturated polyester resin and epoxy resin and other polymer components as basic materials, and inorganic non-metallic granular materials such as quartz sand and calcium carbonate as fillers as the main raw materials. The butt joint method of the fiberglass pipe is flange connection. Flange connection is to install flanges at both ends of the pipe, and then use bolts to tightly connect the two flanges together.

[0003] When the existing fiberglass pipes are butt-jointed, most of them are tightened by flange connection. However, this connection and tightening are relatively single, resulting in a poor overall butt-joint effect. At the same time, auxiliary tools are required to align the two flanges during the butt-joint process, which is rather cumbersome. Therefore, in view of the above problems, we propose a fiberglass pipe with reliable butt joint. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fiberglass pipe with reliable butt joint, so as to solve the problems that when the existing fiberglass pipes are butt-jointed, most of them are tightened by flange connection. However, this connection and tightening are relatively single, resulting in a poor overall butt-joint effect. At the same time, auxiliary tools are required to align the two flanges during the butt-joint process, which is rather cumbersome.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

An internal thread sleeve is fixedly connected to the inside of the left end of the connecting column. An anti-slip sleeve is fixedly connected to the outer wall of the connecting column. An elastic rubber sleeve is sleeved on the outer wall of the left end of the second fiberglass pipe. A first hoop is arranged on the outer side of the upper end of the elastic rubber sleeve. Bolts are arranged on the inner sides of the front and rear ends of the first hoop. A second hoop is arranged on the outer side of the lower end of the elastic rubber sleeve. The lower outer side of the bolt is detachably screwed with a nut. A first gasket is fixedly connected to the right end of the first fiberglass pipe. A second gasket is fixedly connected to the left end of the second fiberglass pipe.
