Problems solved by technology

[0002] At present, the fire hoses used in China, especially the hoses used for high-pressure water mist fire extinguishing, are prone to the problem of quick connectors being disengaged during work due to various accidental reasons.
For example, if figure 1 As shown, in the existing quick joint structure, the spring 9 in the sliding sleeve 3 fails due to common faults such as corrosion, fracture or jamming, which will cause the sliding sleeve 3 to be unable to be positioned correctly, and then the positioning steel ball 10 will fall off, resulting in The left joint body 1 is completely disengaged from the right joint body 2, thus losing the sealing effect of the joint, resulting in the termination of the fire extinguishing agent delivery
In this way, when the fire extinguishing work is carried out normally, there will be a possibility of greater fire losses due to the existence of this serious hidden danger.

Abstract

The invention discloses a safety buckle structure of a quick coupling of a fire extinguishing agent conveying hose. The quick coupling comprises a left coupling body and a right coupling body. The right coupling body is sleeved with a sliding sleeve. The safety buckle structure comprises a safety buckle and a lug seat fixedly installed on the left coupling body. The safety buckle is hinged to a pin shaft A on the lug seat. The safety buckle is always kept in a rotating trend under the effect of a driving mechanism, and during connection of the quick coupling, the safety buckle is buckled on a protruding part corresponding to the sliding sleeve. The safety buckle structure is arranged on a quick coupling of an existing fire control fire extinguishing agent conveying hose, the connected quick coupling can be effectively prevented from being disengaged accidentally, stable and reliable connection of the coupling is guaranteed, and it is guaranteed that a fire extinguishing agent is safely and reliably conveyed for fire extinguishing.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to a safety locking structure of a quick joint of a fire extinguishing agent conveying hose. Background technique [0002] At present, the fire hoses used in China, especially the hoses used for high-pressure water mist fire extinguishing, are prone to the problem of quick connectors being disengaged during work due to various accidental reasons. For example, if figure 1 As shown, in the existing quick joint structure, the spring 9 in the sliding sleeve 3 fails due to common faults such as corrosion, fracture or jamming, which will cause the sliding sleeve 3 to be unable to be positioned correctly, and then the positioning steel ball 10 will fall off, resulting in The left joint body 1 is completely disengaged from the right joint body 2, thereby losing the sealing effect of the joint, resulting in the termination of the fire extinguishing agent delivery. Like this...
