Description

Technical Field

[0001] The utility model relates to the field of fiberglass pipes, in particular to the connection technology of fiberglass pipes. Background Art

[0002] At present, for the telescopic seal connection between fiberglass pipes, two grooves are respectively machined at each end of the pipes, rubber rings are respectively sleeved, and then sleeves are installed. The sleeves compress the rubber rings for sealing, and the telescopic adjustment is carried out back and forth according to the deformation of the hull structure, as Figure 1 shown.

[0003] The prior art has the following disadvantages: two rubber ring grooves need to be machined on the pipes respectively; two rubber rings need to be installed respectively; the disassembly is cumbersome and inconvenient; the comprehensive installation cost is relatively high. Content of the Utility Model

[0004] The technical problem to be solved by the utility model: for the telescopic seal connection between two fiberglass pipes, two rubber ring grooves need to be machined on each fiberglass pipe, and rubber rings are installed in each rubber ring groove. The disassembly is cumbersome and the comprehensive installation cost is relatively high.

[0005] To solve the above technical problem, the utility model provides the following technical solution: a seal connection structure for fiberglass pipes, including a groove opened at the end of the fiberglass pipe, a seal rubber strip and a connector. For two connected fiberglass pipes, only one groove is opened at the end of each fiberglass pipe. The seal rubber strip is sleeved on the ends of the two connected fiberglass pipes. The connector cooperates with the grooves of the two fiberglass pipes to connect the ends of the two fiberglass pipes together, and the connector wraps the seal rubber strip.

[0006] A platform is provided at the end of the fiberglass pipe, and the groove is opened on the platform. The platform has the function of thickening the end of the fiberglass pipe. The groove is opened on the platform, and the end of the fiberglass pipe has sufficient connection strength.

[0007] The two connected fiberglass pipes are respectively a left fiberglass pipe and a right fiberglass pipe. The connector includes a left half connector and a right half connector. The inner flange of the left half connector fits into the groove at the end of the left fiberglass pipe, and the inner flange of the right half connector fits into the groove at the end of the right fiberglass pipe. The left half connector and the right half connector are connected by a connecting piece.

[0008] One side wall of the groove is a straight wall, and the other side wall of the groove is an inclined wall. Compared with the inclined wall, the straight wall is closer to the connection end face of the fiberglass pipe where the groove is located. After the connected fiberglass pipes are installed on the hull, they need to be adjusted for back-and-forth telescopic movement according to the deformation of the hull structure. For the two connected fiberglass pipes, there is a gap between their connection end faces. The sealing rubber strip is sleeved on the connection ends of the two fiberglass pipes to seal the connection between the two fiberglass pipes. The connector uses a steel connector to realize the connection of the two fiberglass pipes. The design of the inclined wall of the groove allows a certain range of telescopic movement of the two connected fiberglass pipes to adapt to the deformation of the hull structure. The design of the straight wall of the groove makes the connector abut against the straight wall of the groove, controlling the maximum telescopic amount between the two fiberglass pipes, and moreover, the connection between the two fiberglass pipes can be maintained.

[0009] In the utility model, a platform and a groove are processed at the end of the fiberglass pipe. Two grooves of the two pipes share a rubber ring, and they can be connected by compressing the rubber ring with a steel connector, without the need for the traditional connection form of multiple rubber rings. The comprehensive cost of the product materials is low, the installation cost is reduced, the disassembly is convenient, the mechanical properties are significantly improved, and the product quality is excellent.

[0010] The utility model overcomes the technical problem that most of the telescopic seal connections between fiberglass pipes adopt the double O-ring form, that is, two rubber grooves are processed at one end of the pipe respectively, rubber rings are installed, and then sleeves are installed to compress the rubber rings for sealing. The installation process is complex and cumbersome, and the processing cost is relatively high. Brief Description of the Drawings

[0021] Combined with Figure 2 , Figure 3 , a sealing connection structure for fiberglass pipes, including a groove 10 opened at the end of the fiberglass pipe, a sealing strip 20 and a connector 30. For two connected fiberglass pipes, only one groove is opened at the end of each fiberglass pipe. The sealing strip is sleeved on the ends of the two connected fiberglass pipes. The connector cooperates with the grooves of the two fiberglass pipes to connect the ends of the two fiberglass pipes together, and the connector wraps the sealing strip.

[0022] A platform 40 is provided at the end of the fiberglass pipe, and the groove 10 is opened on the platform.

[0023] The two connected fiberglass pipes are respectively the left fiberglass pipe and the right fiberglass pipe. The connector 30 includes a left half connector and a right half connector. The inner flange of the left half connector fits into the groove at the end of the left fiberglass pipe, and the inner flange of the right half connector fits into the groove at the end of the right fiberglass pipe. The left half connector and the right half connector are connected by a threaded connector.

[0024] One side wall of the groove 10 is a straight wall 11, and the other side wall of the groove is an inclined wall 12. Compared with the inclined wall, the straight wall is closer to the connection end face of the fiberglass pipe where the groove is located.

[0025] For the two connected fiberglass pipes, there is a gap at their connection end faces. The sealing strip 20 is sleeved on the connection ends of the two fiberglass pipes to seal the connection of the two fiberglass pipes. The connector 30 is made of a steel connector to realize the connection of the two fiberglass pipes. The design of the inclined wall 12 of the groove can allow a certain degree of expansion and contraction of the two connected fiberglass pipes to adapt to the deformation of the hull structure. The design of the straight wall 11 of the groove makes the inner flange of the connector 30 abut against the straight wall of the groove. In this way, the connection of the two fiberglass pipes can be ensured, and at the same time, the maximum expansion and contraction amount between the two fiberglass pipes can be controlled.
