Problems solved by technology

[0002] Explosion-proof flexible connecting pipes are suitable for places with explosive gases or mixtures. They are used as the incoming and outgoing lines of explosion-proof electrical equipment or steel pipe wiring for bending, and are used for connections in places where wiring is difficult to bend. The two ends of the existing explosion-proof connecting pipes are mostly hoses and two The connecting bolts at the end are directly connected. When the pressure is high or the use time is long, the hose is easy to fall off from the connecting bolts, which will affect the normal use of the equipment.
In addition, most of the existing outer protective sleeves of hoses are made of rubber materials. Rubber hoses have little bending at low temperatures, are prone to aging, have a low service life, and are easy to burn, threatening the safe use of equipment, and even causing casualties in severe cases. and huge economic losses

Embodiment 1）

[0020] See figure 1 , the explosion-proof flexible connecting pipe of the present invention has a connecting hose 1 and a connecting head 2 located at both ends of the connecting hose 1; a compression sleeve 3 is also provided outside the connection between the connecting hose 1 and the connecting head 2, which further ensures that the connecting hose The reliability of the connection between 1 and connector 2 fully guarantees the safety of the equipment.

[0021] As a preferred solution of the present invention, the connecting hose 1 includes an outer protective sheath 11 and a metal hose 12 inside the protective sheath 11 . Preferably, the protective sheath 11 on the outside of the metal hose 12 is braided with stainless steel wire, which can satisfy the large flexibility of the connecting pipe, and also has anti-aging and corrosion resistance, which can greatly increase the service life of the connecting pipe.

[0022] The connection head 2 of the connecting hose 1 of the ...

Abstract

The invention relates to a connecting pipe, in particular to an explosion-proof flexible connecting pipe. The explosion-proof flexible connecting pipe comprises a connecting hose and connectors at the two ends of the connecting hose, and compacting sleeves are arranged outside the connecting parts between the connecting hose and the connectors. As the compacting sleeves are additionally arranged at the connecting parts between the connectors and the connecting hose, the bonding strength of the hose and the connectors is greatly improved, the mutual connecting reliability is improved, and accordingly, the service life of the connecting pipe is prolonged.
