Embodiment Construction

[0018] There are many types of fire-fighting interfaces, and the technical solution of the present invention will be further described below by taking the hose interface as an example.

[0019] Such as figure 1 As shown, the fire-fighting interface includes a left interface 1 and a right interface 2 (the claws of the left and right interfaces have the same shape, and the right interface is turned over to become the left interface). The buckle 11 extends axially from its end face for a section and then bends to form a claw-shaped hook groove; the end face of the right interface 2 is uniformly distributed with right claws 21 along the circumference, and the right claw 21 extends axially from its end surface for a section and then bends to form The claw-shaped hook groove, wherein the bending directions of the left and right claws are opposite; the left and right claws are buckled together to form a fire protection interface.

[0020] Such as figure 2 , 3 , 4, in addition to ...

Abstract

The invention discloses a fire coupling comprising a left coupling and a right coupling, left buckling claws are evenly distributed in the circumferential direction of the end face of the left coupling, axially extend by a segment from the end face of the left coupling and then are bent to form claw-shaped hooking grooves. Right buckling claws are evenly distributed in the circumferential direction of the end face of the right coupling, axially extend by a segment from the end face of the right coupling and then are bent to form claw-shaped hooking grooves, wherein the bending direction of the left buckling claws is contrary to that of the right buckling claws. The left buckling claws and the right buckling claws are mutually buckled to form the fire coupling. The fire buckling has the advantages that the buckling claws are evenly distributed in the circumferential direction of the couplings, the large number of buckling claws are arranged, and the fire coupling formed in a buckling mode is high in strength, not prone to fracture and capable of bearing high-strength impact of water supplying pressure and meeting the requirement for popularizing and applying a high-power fire fighting water tanker device; the fire coupling is provided with lock catches which can prevent the buckling claws from loosening after fastening, and the tripping phenomenon can not happen; the fire coupling is adjustable freely in size and more suitable for large-caliber connecting parts.

Description

technical field [0001] The invention relates to an interface, in particular to an interface for fire protection. Background technique [0002] The fire-fighting interface is mainly used for the connection between the hose, fire hydrant and water gun, etc., to carry out the fire-fighting work of transporting water or mixed liquid. Existing fire-fighting interfaces are mainly divided into inner buckle type and buckle type according to the buckle connection method. At present, the following defects generally exist in the fire-fighting interface: the interface is poor in strength, easy to break, and cannot withstand the impact of high-intensity water supply pressure; the interface after buckling is easy to disengage during use, and there is no self-locking device. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a high-strength anti-drop fire-fighting interface. [0004] Technical solution: The fire-fighting interface of...
