The attached drawings are schematic diagrams of main components of the device, do not represent the external dimension, the connection mode, the assembly form, the position relation and the like of the device, and omit parts of manual valves, pipe fittings and the like.

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

The patent provides a plurality of parallel schemes, and different expressions belong to an improved scheme based on a basic scheme or a parallel scheme. Each solution has its own unique features.

The utility model provides a fire hydrant structure that prevents striking contains the fire hydrant, a serial communication port, the oral area of fire hydrant below fill in screwed internal connection head 3, 3 outsides of internal connection head contain the screw thread, the oral area inner wall of below contains the screw thread, the internal connection head is connecting the screw thread of the oral area inner wall of below, internal connection head is connecting internal hose 5, the internal hose opposite side contain the below connector, the below connector is the nipple, the nipple fills in horizontal pipe 7 inside and rather than threaded connection, oral area and horizontal pipe of below between through the butt joint of bottom ring flange, the bottom ring flange between through the bolt-up, the bolt be the bolt of aluminium material. The technical scheme of the invention has the following substantial technical effects and the realization process: a method for preventing collision is characterized in that the fire hydrant structure is used, and comprises the following steps that when the fire hydrant above is in a roadside and is collided by a vehicle, a bolt made of aluminum can be deformed or even broken, and a part of impact kinetic energy can be counteracted; at this time, although a gap appears on the flange plate fixed by the aluminum material at the lower part, the inner hose exists, so that the water flow cannot leak.
