Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a fire hydrant with a quick connection joint. Background Art

[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facility. Their main function is to control combustible materials, isolate combustible materials, and eliminate fire sources. Fire hydrants are divided into indoor fire hydrants and outdoor fire hydrants.

[0003] When a fire hydrant is in use, it is generally necessary to install a water pipe at the water outlet of the fire hydrant through a joint, and then by rotating the valve on the top of the fire hydrant, the water inside the fire hydrant is transported from the water outlet to the water pipe under pressure. However, the existing installation method of the water outlet of the fire hydrant and the joint usually adopts a threaded connection or a plurality of sets of card slots. The above connection method results in a long connection period between the fire hydrant and the joint. After the card slot is used for card installation, if the water pipe is pulled by external force, it is very easy to cause the card joint to loosen or fall off, which is extremely inconvenient to use and affects the efficiency of fire rescue. Therefore, the inventor proposes a fire hydrant with a quick-connect joint to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a fire hydrant with a quick-connect joint to solve the problem that the existing fire hydrant water outlet and joint installation method usually adopts threaded connection or multiple sets of card slots, and the use of the above connection method leads to a long connection period between the fire hydrant and the joint, and after the card slot is used for card installation, if the water pipe is pulled by external force, it is very easy to cause the card joint to loosen or fall off, which is very inconvenient to use and affects the efficiency of fire rescue.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fire hydrant with a quick-connect joint, comprising a fire hydrant body, a mounting head is provided on one side of the fire hydrant body, a first limit block is provided on the inner side of one end of the mounting head, and a second limit block is provided on the outside of the mounting head, a clamping joint is provided on the inner side of the mounting head, a clamping block is provided on the outside of one end of the clamping joint, and the clamping block is arranged in an L-shaped structure, and a limiting convex ring is provided at one end of the mounting head so that one end of the clamping block outside the clamping joint can be buckled on one end of the first limit block.

[0006] As a technical solution of the utility model, an annular boss is arranged outside the center of the clamping joint, and multiple groups of mounting grooves are arranged inside one end of the annular boss to facilitate the movable rod to be movably installed inside the mounting groove.

[0007] As a technical solution of the utility model, a movable rod is movably provided at the output end of the installation slot, and a spring is provided at one end of the movable rod inside the installation slot so that the spring pushes the movable rod to extend outward.

[0008] As a technical solution of the utility model, an annular limiting device is arranged at one end of the movable rod, and an annular groove is arranged inside one end of the annular limiting device so as to facilitate the matching of the annular groove and the limiting convex ring.

[0009] As a technical solution of the utility model, a plurality of limiting grooves are arranged in an inner ring at one end of the annular limiting device, and a push ring is arranged at an outer end of the annular limiting device so as to push the annular limiting device to move along the outside of the clamping joint through the push ring.

[0010] As a technical solution of the utility model, a mounting pipe is arranged at one end of the annular boss, and a water pipe is arranged outside the mounting pipe so that the water pipe can be installed outside the mounting pipe.

[0011] As a technical solution of the utility model, a control chamber is arranged at the top of the fire hydrant body, and a screw rod is rotatably arranged inside the top of the control chamber so that the screw rod can be rotatably installed at the top of the control chamber.

[0012] As a technical solution of the utility model, a hand wheel is arranged at the top end of the screw rod, and a sealing plug is arranged at the bottom end of the hand wheel, so that the screw rod can drive the sealing plug to move downward.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the fire hydrant with a quick-connect joint is not only reasonably structured, convenient to use and simple to maintain later, but also has the following advantages:

[0014] By setting multiple groups of first limit blocks on the inner side of the output end of the installation head and multiple groups of second limit blocks on the outside of the installation head, the card joint is then inserted into the installation head and the card joint is rotated clockwise so that one end of the card block outside the card joint is buckled at one end of the first limit block, and then the movable rod is pushed by the spring so that the movable rod drives the annular limit device to extend forward. At the same time, the annular limit device is installed on the outside of the second limit block through the limit groove, so that the connecting head can be quickly docked and fixed, which solves the problems of inconvenient installation of fire hydrants and joints and long installation period, thereby improving rescue efficiency.
