Problems solved by technology
The advantages of this type of interface are: the product structure is simple, the manufacturing cost is low, and there is no distinction between male and female, and it is widely used in fire-fighting facilities in ordinary buildings; the disadvantage is: the product is not high in pressure, and the claws protrude outside, which is very easy to be bumped. Injury, due to the occurrence of twisted straps during use, the connection of the hose may fall off, affecting fire fighting and rescue
The disadvantage is: there are many parts, the product manufacturing cost is high and there are male and female

The invention discloses a firefighting connecting port which comprises a female connecting port and a male connecting port. The firefighting connecting port further comprises a lock sleeve and a limiting structure, wherein the male connecting port is sleeved with the lock sleeve, the lock sleeve is in buckled connection with the female connecting port, and the limiting structure is arranged on the male connecting port and used for limiting the lock sleeve. An elastic element which exerts acting force on the lock sleeve so as to enable the lock sleeve and the female connecting port to maintain a buckled state is arranged between the lock sleeve and the female connecting port. According to the firefighting connecting port, by arranging the lock sleeve on the male connecting port to enable the lock sleeve to be in buckled connection with the female connecting port and by arranging the elastic element to enable the lock sleeve to be tightly buckled with the female connecting port, tripping of the lock sleeve, the female connecting port and the male connecting port can be avoided, and safety and reliability of the firefighting connecting port are guaranteed.
Description
Technical field [0001] The present invention relates to fire fighting equipment, in particular, the present invention relates to a fire fighting interface. Background technique [0002] At present, the main types of fire interface products used in China are divided into internal button type, clip type and threaded type, and these three different types of connection transition special-shaped interfaces. [0003] 1. The internal buckle interface is an interface that relies on two pairs of buckle claws to connect with the inner chute, and its nominal pressure is 1.6MPa; the internal buckle interface is equipped with two symmetrical buckle claws, and its arc length is specified by the country as 30°. When the interface is connected, the actual pressure-bearing area is restricted by the arc length, so the interface has been used only for (normal pressure) below 1.6MPa. The advantages of this type of interface are: the product structure is simple, the manufacturing cost is low, and ther...
