Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a fire hydrant convenient for fast connecting a water receiving port of a water hose comprises a main body 1, both sides of the upper portion of the main body 1 are fixedly connected with the water receiving port 2, the upper end of the main body 1 is movably sleeved with a rotating handle 3, one end of the inner side of the water receiving port 2 is fixedly connected with a limiting ring 22, the middle portion of the inner wall of the water receiving port 2 is provided with a mounting groove 21, the bottom of the rotating handle 3 is fixedly connected with a rotating shaft 4, the bottom end of the rotating shaft 4 is in threaded connection with a threaded sleeve 5, both sides of the threaded sleeve 5 are fixedly connected with a limiting rod 6 movably sleeved with the main body 1, the bottom of the threaded sleeve 5 is fixedly connected with a valve core 7, the upper portion of the rotating shaft 4 is fixedly connected with a worm wheel 8, the outer side of the worm wheel 8 is engaged with a worm 9, the bottom of the worm 9 is provided with threads, the compression chamber 12 that is in worm wheel 8 below is seted up on the upper portion of main part 1, the upper portion threaded connection of pivot 4 has the clamp plate 13 that cup joints with compression chamber 12 activity, the middle part fixedly connected with of main part 1 is located the first gasbag 14 of compression chamber 12 below, the side fixedly connected with second gasbag 15 that water receiving port 2 is close to spacing ring 22 one end, gas passage 16 that is connected with first gasbag 14, the 15 inflation inlets of second gasbag is seted up to the bottom of compression chamber 12, the inside joint of 2 of water receiving ports has hosepipe joint 17.

Wherein, the threaded rings 10 are divided into two groups which are symmetrical up and down, and the threads of the two threaded rings 10 are arranged in opposite directions, when the fire hydrant needs to be used, an operator only needs to directly insert the hose connector 17 into the water receiving port 2, then rotate the handle 3 counterclockwise, at the moment, the rotating shaft 4 can drive the worm wheel 8 to rotate synchronously, so that the worm wheel 8 drives the worm 9 to rotate, the worm 9 rotates to enable the threaded rings 10 which are distributed up and down to move towards the middle simultaneously, the clamping block 11 is driven to move towards the middle, the hose connector 17 can be clamped and fixed, meanwhile, in the process of rotating the handle 3, the rotation of the bottom of the rotating shaft 4 can drive the threaded sleeve 5 to move upwards, the valve core 7 can be driven to move upwards, therefore, the valve core 7 can be opened while the fire hose is fixed, the arrangement cancels the action of screwing in the water receiving port 2 when the hose connector 17 is, the operations of opening the valve core 7 and fixing the water hose joint 17 can be realized only by inserting the water hose joint 17 and then rotating the rotating handle 3, so that the water hose joint is simpler and more convenient, the time is saved, and the fire fighting personnel can conveniently and quickly fight fire.

The arc diameters of the two clamping blocks 11 are equal and equal to the outer diameter of the water hose joint 17, so that the water hose joint is conveniently fixed, and the water hose joint is prevented from loosening and leaking water and influencing the water outlet effect of the water hose.

Wherein, be provided with the sealing ring between pivot 4 and the clamp plate 13, in the rotatory handle 3 of operating personnel, clamp plate 13 can move down in step, extrude the inside air of compression chamber 12, extrude into first gasbag 14 and second gasbag 15 with air wherein, make two gasbag inflation, can seal up hose coupling and pivot 4, prevent the leakage of the inside liquid of fire hydrant, and can prevent that liquid from flowing into in the gap that pivot 4 and main part activity cup jointed, avoid the pivot to rust.

Wherein, case 7 is circular setting, and the rubber pad has been cup jointed in the outside of case 7, through the setting of threaded sleeve 5 for case 7 can shift up when rotatory in pivot 4, opens the valve, and the case shifts up the in-process, and pivot 4 can not reciprocate, guarantees that worm wheel 8 can mesh with worm 9 all the time, can not influence the fixed work that hosepipe connects 17.

Working principle, when needing to use the fire hydrant, operating personnel only need with hosepipe joint 17 disect insertion water receiving mouth 2 inside, then anticlockwise rotation handle 3, pivot 4 can drive worm wheel 8 synchronous revolution this moment, make worm wheel 8 drive worm 9 rotatory, worm 9 is rotatory to make the screw ring 10 of upper and lower distribution move to the centre simultaneously, drive fixture block 11 and move to the centre, can press from both sides tight fixed to hosepipe joint 17, simultaneously, in the in-process of rotatory rotation handle 3, pivot 4 bottom is rotatory can drive threaded sleeve 5 and go upward, can be with driving case 7 and go upward, therefore, can open case 7 when fixed fire hose, this kind of setting has cancelled hosepipe joint 17 action that need screw in water receiving mouth 2 when installing, to operating personnel, only need insert hosepipe joint 17, then rotatory handle 3 just can realize opening case 7, The operation of fixed hosepipe joint 17, it is more succinct, convenient, save time moreover, the fire fighter of being convenient for carries out the work of fighting a fire fast, and on the same hand, after the work of fighting a fire is accomplished, only need clockwise rotation handle 3, can close the valve, and the pine takes off the hosepipe joint.
