By setting a connection part, it solves the problem that the traditional connection technology mainly uses threaded sleeve connection. However, this traditional connection technology has the following defects: First, the connection process requires repeated rotation and tightening, which is cumbersome and results in low installation efficiency. Second, the threaded structure is prone to loosening and stripping under long-term use or high-pressure impact, causing the fire hose to fall off.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a multi-layer pressure-resistant and wear-resistant fire hose connection device, including a fire hose, and further including: a pipe section, which is disposed on the fire hose; a connecting section, which is disposed on the pipe section; and a reinforcing section, which is disposed on the connecting section; wherein, the outer layer of the fire hose is a wear-resistant layer, the middle layer is a pressure-resistant layer, and the innermost layer is a waterproof layer.

[0013] 1. By setting a connecting part, when connecting hose one and hose two, first pull the anti-slip moving block on the insert block upwards, causing the insert block to move upwards synchronously. This operation can prevent the insert block from obstructing the locking block on connector two from entering the locking groove of connector one. At the same time, during the upward movement of the insert block, the springs sleeved on the outer wall of the two slide rods will be compressed, allowing them to accumulate elastic potential energy to provide power for subsequent reset. After the insert block moves to the appropriate position, the locking block of connector two can be inserted into the locking groove of connector one to complete the initial connection. At this time, the anti-slip moving block is released, the compressed spring releases energy, and pushes the insert block downwards to insert it into the slot of the locking block, thereby realizing the quick connection of hose one and hose two. When disassembling, simply repeat the above operation in reverse. Compared with the traditional threaded sleeve connection method, this structure greatly simplifies the operation process and significantly improves work efficiency.

[0014] 2. By setting up a reinforcement part, after the connection between connector one and connector two is completed, in order to prevent the connector from becoming loose due to accidental contact with the insert block, an upper hoop and a lower hoop can be used for reinforcement and protection. The specific operation is as follows: First, put the upper hoop and the lower hoop on the connection between connector one and connector two. Then, insert the screw that is rotatably installed on the upper hoop into the limiting groove of the lower hoop limiting block. Finally, turn the manual knob on the outer wall of the screw to tighten the screw, so that the upper and lower hoop fit tightly together, thereby firmly fixing the connector and enhancing the connection stability.
