Problems solved by technology
[0003] When it is necessary to carry out fire extinguishing at high altitudes, the traditional method is to directly splice the hoses together with joints in order to extinguish the fire. Due to the gravity of the hoses and water, it needs to be pulled manually, which may cause the hoses to slip and cause deformation. At the same time, it is easy to It consumes physical strength, and the operation remains unchanged, which reduces the speed and efficiency of fire extinguishing

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] see Figure 1-5 As shown, a quick safety joint for a fire hose includes a joint body 1 and a fixing mechanism 2 installed inside the joint body 1. The fixing mechanism 2 includes a storage tank 21, a rotating rod 22, a connecting rod 23, a pressing Block 24, card slot 25, bayonet pin 26 and first spring 27, the same said joint body 1 is provided with said storage slot 21 on both sides of the symmetry, the interior of two said storage slots 21 are instal...

The invention discloses a quick safety joint for a fire hose, comprising a joint body, a fixing mechanism, a storage tank, a rotating rod, a connecting rod, a press block, a locking groove, a locking pin, a first spring, a rotating mechanism, a rotating shaft, and a torsion spring and clamping mechanism. The beneficial effects of the present invention are: by pressing the pressing block, the pressing block moves downwards, thereby conveniently driving the connecting rod to move downwards, so that the bayonet is separated from the bayonet under the action of the connecting rod, and then the rotating rod rotates under the rotating shaft and the torsion force. Turn under the action of the spring, so that the rotating rod is opened from the inside of the storage tank and conflicts with the guardrail, and then release the button, so that the bayonet and the connecting rod return to their original positions under the action of the first spring, and then by rotating the rotating mechanism, The joint body and the guardrail are tightly clamped, thereby avoiding the consumption of a large amount of physical strength due to the gravity of the water and the hose when carrying out high-altitude fire extinguishing. At the same time, the operation is easy to improve the efficiency and speed of fire extinguishing.
Description
technical field [0001] The invention relates to a safety joint, in particular to a quick safety joint for a fire hose, and belongs to the technical field of fire protection. Background technique [0002] The fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids. The traditional fire hose is lined with rubber and the outer surface is wrapped with flax braid. The advanced fire hose is made of polymer materials such as polyurethane. As a result, there are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or connected to the nozzle to increase the liquid injection pressure. The fire hose is divided into a lined fire hose and a leaking fire hose With two categories. [0003] When it is necessary to carry out fire extinguishing at high altitudes, the traditional method is to directly splice the hoses together with joints in order to extinguish the fire. Due to the gravity of the ...
