Description
Technical Field
The utility model relates to a machine parts technical field, concretely relates to flexible connector.
Background
In recent years, with the comprehensive development of rural domestic sewage treatment projects, integrated sewage treatment equipment is more and more popular. This kind of equipment concentrates the equipment room and sewage treatment unit to arrange in same box, and the pipeline passes the box steel sheet and can make equipment room and sewage treatment unit have the gap, and water in the sewage treatment unit can be followed gap infiltration equipment room and damaged fan, instrument, arouses the circuit short circuit, leads to the unable normal operating of integration sewage treatment equipment. Sealing between the pipe and the hole in the tank is therefore important.
When the pipeline passes through a wall body or a box body, the gap between the pipeline and the through hole cannot be sealed in a welding mode due to the fact that different materials are used, and sealing glue is generally adopted for sealing. But the use of the sealant can not completely block and is inconvenient to construct, the vibration of the pipeline can lead the sealant to be loose, and the problem of water seepage can not be solved. The flange plate is too high in connection cost and inconvenient to construct, corrosion can occur for a long time, and ideal effects are difficult to achieve.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention provides a flexible connector that is corrosion resistant, can be used between any materials, and has good sealing performance and low cost.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a flexible connector comprises a wedge-shaped fastening plug, a flexible connecting piece sleeved on the outer side of the wedge-shaped fastening plug and a steel hoop fastened on the outer side of the flexible connecting piece; the flexible connecting piece is sleeved on the pipeline penetrating through the hole and is positioned between the hole and the pipeline; the wedge-shaped fastening plug is inserted between the pipe and the flexible connection.
Aiming at the technical characteristics, the connector can be used for sealing between a pipeline and a hole made of any material, the flexible connecting piece is sleeved on the pipeline and is arranged between the pipeline and the hole, the flexible connecting piece and the pipeline are fixed through the steel hoop, and then the wedge-shaped fastening plug is inserted between the pipeline and the flexible connecting piece through external force to realize the sealing between the pipeline and the hole; the flexible connecting piece also plays a role in buffering, so that the pipeline is prevented from being damaged due to excessive impact force, and the service life of the pipeline is prolonged; meanwhile, the connector is simple in combination, convenient to disassemble, capable of being repeatedly used, low in cost, free of influence of materials, suitable for various pipelines and walls and free of limitation of construction environments.
Preferably, the longitudinal section of the wedge-shaped fastening plug is wedge-shaped and consists of a hollow cylindrical pressure seat and a circular table above the pressure seat. When the flexible connecting piece is used, the flexible connecting piece can be inserted between the pipeline and the flexible connecting piece conveniently, and the construction difficulty is reduced.
Preferably, the flexible connecting piece is a hollow cone frustum, and a cylindrical boss I and a boss II are respectively arranged at the upper end and the lower end of the cone frustum; the boss II is positioned between the wedge-shaped fastening plug and the hole wall; the steel hoop is fixed on the outer side of the boss I. The boss I can facilitate the fixation of the steel hoop and is beneficial to the sealing between the flexible connecting piece and the pipeline; the boss II is convenient for sealing between the flexible connecting piece and the hole and between the flexible connecting piece and the wedge-shaped fastening plug.
Preferably, the sum of the wall thickness of the wedge-shaped fastening plug and the wall thickness of the flexible connector is larger than the gap between the pipe and the hole. The pipeline and the hole can be tightly combined through interference connection, and the water insulation purpose is achieved.
The utility model has the advantages that:
the utility model has simple structure combination, convenient installation and disassembly, easy manufacture of the components, low cost, repeated utilization and resource waste avoidance; meanwhile, the flexible connecting piece plays a role in buffering and has a certain protection effect on the pipeline and the wall body; the construction is simple, and the method is suitable for various pipelines and walls and is not limited by the construction environment; good sealing performance and good water insulation performance.

Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1-4, a flexible connector for sealing between a pipe 1 and a hole in a box or wall comprises a wedge-shaped fastening plug 4, a flexible connector 2 fitted around the outside of the wedge-shaped fastening plug 4, and a steel ferrule 3 fastened to the outside of the flexible connector 2. The longitudinal section of the wedge-shaped fastening plug 4 is wedge-shaped and consists of a hollow cylindrical pressure seat 5 and a circular table 6 positioned above the pressure seat 5. The flexible connecting piece 2 is a hollow cone frustum 7, and a cylindrical boss I8 and a boss II9 are respectively arranged at the upper end and the lower end of the cone frustum 7; the boss II9 is located between the wedge-shaped fastening plug 4 and the hole wall; the steel hoop 3 is fixed on the outer side of the boss I8. The steel hoop 3 is of an existing design.
Sleeving the flexible connecting piece 2 on the pipeline 1 penetrating through the hole and between the hole and the pipeline 1; the wedge-shaped fastening plug 4 is inserted between the pipeline 1 and the flexible connecting piece 2, so that the pipeline 1 and the hole are sealed, and the problem of water overflow between the pipeline 1 and the hole is solved. The sum of the wall thickness of the wedge-shaped fastening plug 4 and the wall thickness of the flexible connector 2 is larger than the clearance between the pipeline 1 and the hole, so that interference connection is realized, the sealing performance between the pipeline 1 and the hole is improved, and water seepage is avoided.
