[0002] A fire hydrant is a fixed fire-fighting facility. It is installed on a water pipe and is closed under normal circumstances. In the event of a fire, the fire hydrant can be quickly opened through the switch on the fire hydrant and connected to the fire pipe. A large amount of water can be output through the fire hydrant to extinguish the fire. Fire hydrants are usually cast with metal materials, which are high in strength and resistant to high temperatures. They will not be damaged even in a serious fire or when hit by heavy objects. They are very durable and reliable, and are easy to use, which can effectively reduce the losses caused by a fire.

[0003] Although the above patent can solve the corresponding technical problems, there are still certain defects: before using the existing fire hydrant, it is necessary to use tools such as hydraulic pliers to unscrew the plug at the connecting port of the water outlet pipe, and screw the thread of the port of the fire water pipe into the water outlet pipe after removing the plug, so as to connect the fire water pipe to the water outlet pipe of the fire hydrant. When using it, it is necessary to use additional tools such as hydraulic pliers, which is very cumbersome to open. When installing the fire water pipe, it is also necessary to force the thread of the fire water pipe to align with the water outlet pipe and screw it in to fix it. There are many steps to use, which is time-consuming and not conducive to rapid control of the fire. Utility Model Content

[0021] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0022] See also Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a fire hydrant that is easy to install, including a plug body 1 with an opening and closing member inside and a connecting water pipe 2 arranged on the side wall of the plug body 1 and connected to the plug body 1, the connecting water pipe 2 includes a water pipe 21 arranged on the side wall of the plug body 1 and connected to the plug body 1, and a shrinkable fixed pipe 22 is provided at the end of the water pipe 21, and the shrinkable fixed pipe 22 includes a shrinkable elastic tube 31 arranged at the end of the water pipe 21 and an adsorption block 33 penetrating the inner wall of the shrinkable elastic tube 31, and the adsorption block 33 includes a penetrating setting The through pipe 331 is arranged on the inner wall of the shrinkable elastic tube 31, and the extrusion plate 332 is arranged on the through pipe 331 near the inner wall of the shrinkable elastic tube 31. The extrusion plate 332 is provided with an opening 333. The inner wall of the through pipe 331 is provided with a closing block 334. The closing block 334 is attached to a closing plate 335 on the side surface away from the extrusion plate 332. The fire hose is inserted into the shrinkable fixed tube 22 and the shrinkable fixed tube 22 is squeezed to make it adhere to the outer wall of the fire hose and complete the connection. When in use, the bolt body 1 is in a closed state. At this time, the fire hose is quickly inserted into the connecting water The end of the pipe 2 is contracted, and the contraction elastic tube 31 of the contraction fixing tube 22 contacts the outer surface of the connecting end of the fire water pipe. At this time, the contraction elastic tube 31 is squeezed, and the contraction elastic tube 31 fits the outer surface of the fire water pipe. At the same time, the squeezing causes the squeezing disk 332 of the adsorption block 33 to be squeezed and deformed, and then the air in its inner cavity is squeezed into the closing block 334 through the through pipe 331, and the closing disk 335 on the closing block 334 is pushed by the gas pressure to form a gap between it and the closing block 334, and then the squeezing is stopped to make the squeezing disk 332 recover slightly. At this time The inner cavity of the extrusion disc 332 generates suction, so that the outside air pushes the closing disc 335 to fit again on the closing block 334 and close the closing block 334, thereby generating suction at the opening 333, adsorbing and fixing the fire hose, and cooperating with the friction force of the inner wall of the shrinking elastic tube 31, so that the fire hose will not be separated. At this time, the opening and closing member in the bolt body 1 can be screwed up, so that the water flow enters the connecting water pipe 2 and is output to the outside through the fire hose. During installation, no additional tools are needed, the steps are few, and the installation speed is fast, which is conducive to rapid control of the fire.

[0023] The top of the bolt body 1 is also provided with a twisting handle 4, which is conducive to making the opening and closing of the bolt body 1 more labor-saving and convenient;

[0024] The bottom of the bolt body 1 is provided with a connecting flange 5, which is conducive to making the connection between the bolt body 1 and the water supply pipe more convenient;

[0025] The inner wall of the retractable elastic tube 31 is also provided with a plurality of closed rings 34. In this embodiment, three closed rings 34 are provided, which are conducive to enhancing the sealing between the retractable elastic tube 31 and the fire hose after being installed in the fire hose, and increasing the resistance of the fire hose to detach, making it less likely to fall off;

[0026] The inner cavity of the retractable elastic tube 31 can be detachably filled with a sealing plug 23, which is conducive to inserting the sealing plug 23 to seal the inner cavity of the retractable elastic tube 31 when not in use, and maintaining the inner cavity size of the retractable elastic tube 31. After the sealing plug 23 is quickly pulled out, there is a certain amount of space in the inner cavity of the retractable elastic tube 31, which reduces the resistance when the fire hose is installed;

[0027] The end of the closing plug 23 away from the shrinkable elastic tube 31 is provided with a pull ring 24, which is conducive to making it easier and more convenient to pull out the closing plug 23 without using additional tools;

[0028] The outer wall of the shrinkable elastic tube 31 is also provided with an extrusion plate 32, which is conducive to more uniform extrusion force when squeezing the shrinkable elastic tube 31, so that the shrinkable elastic tube 31 and the fire hose fit better;

[0029] A pull-back sheet 336 is provided between one side of the closing sheet 335 and the closing block 334 , which is beneficial for the closing sheet 335 to recover more quickly after the air is squeezed out, thereby making the suction stronger.

[0030] Working principle of the utility model: When the utility model is used, the plug body 1 is in a closed state. At this time, the fire hose is quickly inserted into the end of the connecting water pipe 2, so that the shrinking elastic tube 31 of the shrinking fixed tube 22 contacts the outer surface of the connecting end of the fire hose. At this time, the shrinking elastic tube 31 is squeezed, and the shrinking elastic tube 31 fits the outer surface of the fire hose. At the same time, the squeezing causes the squeezing disk 332 of the adsorption block 33 to be squeezed and deformed, and then the air in its inner cavity is squeezed into the closing block 334 through the through pipe 331, and the closing disk 335 on the closing block 334 is pushed by the gas pressure, so that a gap is generated between it and the closing block 334. , then stop squeezing to allow the squeezing disk 332 to recover slightly, at which time the inner cavity of the squeezing disk 332 generates suction, allowing the outside air to push the closing disk 335 to fit again on the closing block 334 and close the closing block 334, thereby generating suction at the opening 333, adsorbing and fixing the fire water pipe, and cooperating with the friction force of the inner wall of the shrinking elastic tube 31 to prevent the fire water pipe from detaching, at this time the opening and closing part in the bolt body 1 can be screwed up, and then the water flow can enter the connecting water pipe 2 and be output to the outside through the fire water pipe. During installation, no additional tools are required, the steps are few, and the installation speed is fast, which is conducive to rapid control of the fire.
