This kind of connection structure is because the power unbalance of fire hose both sides in the use leads to the fire hose to deflect easily to lead to water to leak from the clearance with the opposite side of constant head tank, probably even lead to fire hose and fire hydrant to break away from.
Disclosure of Invention
The utility model discloses not enough to prior art, provide a fire hydrant connection structure, this kind of fire hydrant connection structure location is more firm, and the atress is balanced everywhere of fire hose joint outer lane, is difficult to appear leaking, more can not lead to fire hose and fire hydrant to break away from in the use.
In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides a fire hydrant connection structure, includes fire hydrant joint and fire hose joint, be provided with first passageway in the fire hydrant joint, be provided with the second passageway in the fire hose joint, be provided with first ring channel on the fire hose joint outer wall, fire hydrant joint inner wall is provided with the second ring channel, be provided with on the fire hydrant joint with the mounting hole of second ring channel intercommunication, work as the fire hose joint inserts when the fire hydrant connects, first ring channel with the second ring channel flushes, first ring channel with be provided with the location steel ball between the second ring channel, be provided with the end cap on the mounting hole. When the fire hydrant connecting structure is inserted into the fire hydrant connector, the positioning steel balls are arranged from the mounting hole, the positioning steel balls are annularly wound between the first annular groove and the second annular groove, and then the positioning steel balls are blocked by the plugs to prevent the positioning steel balls from falling out.
In the above technical scheme, preferably, the mounting hole is a threaded hole, and the plug is in threaded fit with the mounting hole. By adopting the structure, the plug is easier to install and position.
In the above technical scheme, specifically, the first channel is a stepped channel, the opening side is a large end, and the fire hose coupling is inserted into the large end of the first channel.
In the above technical scheme, preferably, the positioning steel balls are connected in series through a steel cable, and one end of the steel cable is fixed on the plug. By adopting the structure, the positioning steel balls and the plugs are connected into a whole, so that the positioning steel balls and the plugs are more convenient to mount and dismount.
Among the above-mentioned technical scheme, it is preferred, be provided with a plurality of third ring channels on the fire hose connector, be provided with the sealing washer on the third ring channel, the sealing washer with the laminating of first passageway inner wall is sealed. By adopting the structure, the sealing performance is improved, and water leakage in the gap is prevented.
Compared with the prior art, the utility model, following beneficial effect has: when the fire hydrant connecting structure is inserted into the fire hydrant connector, the positioning steel balls are arranged from the mounting hole, the positioning steel balls are annularly wound between the first annular groove and the second annular groove, and then the positioning steel balls are blocked by the plugs to prevent the positioning steel balls from falling out.
Drawings
Fig. 1 is a schematic sectional structure diagram of an embodiment of the present invention.
Fig. 2 is a schematic view of a connection structure between the plug and the positioning steel ball in the embodiment of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 2, a fire hydrant connection structure, including fire hydrant joint 1 and fire hose joint 2, be provided with first passageway 3 in the fire hydrant joint 1, first passageway 3 is the step passageway, the opening side is the main aspects, be provided with second passageway 4 in the fire hose joint 2, be provided with first ring channel 5 on the fire hose joint 2 outer wall, fire hydrant joint 1 inner wall is provided with second ring channel 6, be provided with mounting hole 7 with second ring channel 6 intercommunication on the fire hydrant joint 1, fire hose joint 2 inserts the main aspects of first passageway 3 when the installation, when fire hose joint 2 inserts fire hydrant joint 1, first ring channel 5 flushes with second ring channel 6, be provided with location steel ball 8 between first ring channel 5 and the second ring channel 6, be provided with end cap 9 on the mounting hole 7. In order to facilitate the disassembly and assembly of the plug 9, the mounting hole 7 is a threaded hole, and the plug 9 is in threaded fit with the mounting hole 7.
The positioning steel balls 8 are connected in series through a steel cable 10, and one end of the steel cable 10 is fixed on the plug 9. Specifically, the inner end of the plug 9 is connected with a steel cable 10, a through hole is formed in the center of the positioning steel ball 8, and the steel cable 10 penetrates through the through hole to connect a string of the positioning steel balls 8 in series.
