Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to an anti-theft fire hydrant. Background Art

[0002] Fire hydrants, formally called fire hydrants, are a type of fixed firefighting facility. Their main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. Outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings. They are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to extinguish fires. They can also be directly connected to water hoses and water guns to discharge water for firefighting. Therefore, the outdoor fire hydrant system is also one of the important firefighting facilities for fighting fires.

[0003] The patent with application number 202321223498.9 discloses an anti-theft fire hydrant, a main structure component; the main structure component includes a set base plate; an anti-theft component; the anti-theft component includes a movable groove opened on the upper surface of the base plate, a movable block arranged inside the movable groove, a movable plate connected to the upper surface of the movable block, a mounting hole opened on the side wall of the movable plate, a fixing groove opened on the front side wall of the base plate, a fixing bolt arranged inside the fixing groove, a rear connecting plate arranged on the rear side of the upper surface of the base plate, a slide groove opened on the front side wall of the rear connecting plate, and a slider arranged inside the slide groove.

[0004] The anti-theft fire hydrant, through the main structure component structure and the anti-theft component structure that cooperate with each other, can provide certain protection for the fire hydrant when in use, while preventing the fire hydrant from being stolen. This improves the anti-theft property of outdoor fire hydrants during daily use. However, there are still areas that can be improved. For example, when the device is in use, it is necessary to loosen the nuts on both sides of the fixing bolts. At this time, the movable block can be pushed inward, and the movable block drives the movable plate to move inward, and the slider also moves inward in the slide groove. When the first water outlet pipe passes through the installation hole, the water hose can be connected to the water outlet pipe. However, when using the fire hydrant, every minute and every second is critical. When using it, special parts must be used to loosen the nuts, which is time-consuming and inconvenient to use. In addition, the protection capability of the device is limited and cannot meet current needs. Utility Model Content
