Description

Explosion-proof connecting pipe

Technical Field

The utility model relates to the technical field of explosion-proof equipment, in particular to an explosion-proof connecting pipe.

Background

Explosion-proof connecting pipe is applicable to and has explosive gas or mixture place, and the business turn over line or the steel pipe wiring as explosion-proof electrical equipment are crooked, connect usefulness as the crooked great place of the degree of difficulty of wiring, and the connector at current explosion-proof connecting pipe both ends is mostly connecting bolt, and the outside screw thread of connecting bolt is easy wearing and tearing after handling many times, causes fastening strength to reduce, and connecting hose drops with the connector, influences the normal use of equipment. In addition, the existing explosion-proof connecting pipe is not enough in overall strength.

Disclosure of Invention

The utility model aims to provide an explosion-proof connecting pipe, which is used for solving the problem that the existing explosion-proof connecting pipe is lack of strength.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an explosion-proof connecting pipe, includes the pipe fitting body and is located the connector at pipe fitting body both ends, be formed with a plurality of ring channels sunken to pipe fitting body center pin on the pipe fitting body, the winding has a plurality of solid enhancement pipes on the ring channel.

The utility model is further provided that the reinforcing pipe is an annular pipe, the annular pipe is independently arranged, and the reinforcing pipe is coaxially wound on the annular groove.

The utility model is further provided that the connector comprises a connector and a flange plate, the connector and the flange plate are fixedly connected through bolts, and the flange plate is positioned on the outer side of the connector.

The utility model further provides that the two sides of the pipe fitting body are provided with the reinforcing shafts.

The utility model is further provided that two ends of the reinforcing shaft are fixed on the inner wall of the annular groove.

The utility model has the advantages that the annular groove is formed on the explosion-proof connecting pipe, and the corresponding reinforcing pipe is wound on the annular groove, so that the integral strength structure of the explosion-proof connecting pipe is increased, the strength of the reinforcing pipe in the radial direction can be increased, and the reinforcing shaft is arranged and has the function of reinforcing the strength in the axial direction.

Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

As shown in fig. 1-3, the technical solution of the present invention is that an explosion-proof connection pipe comprises a pipe body 10 and connectors 20 located at two ends of the pipe body 10, wherein a plurality of annular grooves 30 recessed toward a central axis of the pipe body 10 are formed on the pipe body 10, and a plurality of solid reinforcing pipes 40 are wound around the annular grooves 30.

In the middle of this embodiment, strengthen the pipe 40 and be the ring pipe, the ring pipe sets up independently, just strengthen the winding of pipe 40 with the axle center on ring channel 30, in addition in order to protect strengthen pipe 40, can set up corresponding sleeve 50 at the outside adaptability of strengthen pipe 40 and protect it, prevent to strengthen pipe 40 and damage, connector 20 is including connecting 60 and ring flange 70, connect 60 with through bolt fixed connection between the ring flange 70, ring flange 70 is located connect 60's the outside, the both sides of pipe fitting body 10 are provided with reinforcing shaft 80, reinforcing shaft 80's both ends are fixed ring channel 30's inner wall.

The present invention forms the annular groove 30 on the explosion-proof connection pipe and winds the corresponding reinforcement pipe 40 on the annular groove 30, thereby increasing the whole strength structure thereof, the reinforcement pipe 40 can increase the strength in the radial direction, and then the reinforcement shaft 80 is provided, the reinforcement shaft 80 is used for reinforcing the strength in the axial direction.

Certain terms are used throughout the description and claims to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This specification and claims do not intend to distinguish between components that differ in name but not function.
