As a preferred scheme, the rear end of the fixed jaw part is also connected with an extension rod perpendicular to the fixed jaw part and the prying rod, and a square blind hole matched with a torsion bar of the fire hydrant valve is formed in the lower end face of the extension rod.
As a preferable scheme, an extension rod extending downwards is inserted into the square blind hole, a regular pentagonal blind hole matched with a fire hydrant valve torsion bar is formed in the lower end face of the extension rod, and a connecting column matched with the square blind hole is connected to the upper end face of the extension rod.
As a preferred scheme, a groove is formed in the upper end face of the connecting column, and a magnet is embedded in the groove.
As a preferable scheme, the extension rod is fixedly connected to the fixed jaw portion through a bolt, the bolt sequentially penetrates through the upper end of the extension rod and the rear end of the fixed jaw portion, and a polygonal blind hole matched with the torsion bar of the fire hydrant valve is formed in the bottom surface of the bolt.
The utility model has the advantages that: the utility model discloses a improve traditional fire hydrant spanner handle rear end, make the original handle of fire hydrant spanner become the pinch bar to set up the handle in addition and make pinch bar and handle mutually perpendicular, just so combine pinch bar and spanner organically, two instruments that originally need carry have become an instrument through improving the back, and quantity and weight have all obtained the reduction.
The utility model discloses further through connect the extension rod at fixed hubei province portion rear end to set up the square blind hole that matches with fire hydrant valve torsion bar on the extension rod lower extreme terminal surface, just so will need the function integration that is used for the long handle pass spanner of secret fire hydrant who carries originally to the fire hydrant spanner, further reduce instrument quantity and the weight that need carry.
The utility model discloses further through having pegged graft downwardly extending's extension rod in square blind hole, set up the regular pentagon blind hole that matches with fire hydrant valve torsion bar under the extension rod on the terminal surface to enlarge the wildfire hydrant spanner and to the general match scope of the valve torsion bar of different shapes, further reduce instrument quantity and the weight that need carry.
The utility model discloses further through set up the recess on the spliced pole up end to scarf joint magnet in the recess, thereby realize the quick convenient dismouting of spliced pole.
The utility model discloses further utilize bolt and nut to connect the extension rod and fix hubei province portion to set up the polygon blind hole that matches with fire hydrant valve torsion bar on the bolt bottom surface, can be used for subaerial fire hydrant valve torsion bar like this.
Description of the drawings:
the following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a sectional view a-a in fig. 1.
In fig. 1 and 2: 1. fixed jaw portion, 2, activity jaw portion, 3, keep silent, 4, pinch bar, 5, extension rod, 6, square blind hole, 7, extension rod, 8, regular pentagon blind hole, 9, spliced pole, 10, recess, 11, magnet, 12, bolt, 13, polygon blind hole.
The specific implementation mode is as follows:
the following describes in detail a specific embodiment of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the multifunctional fire hydrant spanner comprises a fixed jaw portion 1 and a movable jaw portion 2 which are connected with each other, wherein the rear end of the movable jaw portion 2 is hinged to the middle portion of the fixed jaw portion 1, the front end of the movable jaw portion 2 extends to the front end of the fixed jaw portion 1 and then bends downwards to form an olecranon shape, the front end of the fixed jaw portion 1 also bends downwards to form an olecranon shape, the movable jaw portion 2 and the fixed jaw portion 1 jointly form a jaw 3 for clamping a bolt nut, and the multifunctional fire hydrant spanner is characterized in that the rear end of the fixed jaw portion 1 extends backwards to form a pry bar 4, and the free end of the pry bar 4 bends downwards slightly and is sharp, so that the multifunctional fire hydrant spanner can be conveniently inserted into a hole on a ground.
The rear end of the fixed jaw part 1 is also connected with an extension rod 5 which is perpendicular to the fixed jaw part 1 and the pry bar 4, and a square blind hole 6 matched with a torsion bar of the fire hydrant valve is formed in the lower end face of the extension rod 5.
The square blind hole 6 is internally inserted with an extension rod 7 extending downwards, the lower end face of the extension rod 7 is provided with a regular pentagon blind hole 8 matched with a fire hydrant valve torsion bar, and the upper end face of the extension rod 7 is connected with a connecting column 9 matched with the square blind hole 6.
The upper end face of the connecting column 9 is provided with a groove 10, and a magnet 11 is embedded in the groove 10.
The extension rod 5 is fixedly connected to the fixed jaw portion 1 through a bolt 12, the bolt 12 sequentially penetrates through the upper end of the extension rod 5 and the fixed jaw portion 1, and a polygonal blind hole 13 matched with a torsion bar of the fire hydrant valve is formed in the bottom surface of the bolt 12.
The utility model discloses the working process is: for the fire hydrant on the ground, firstly, the fire hydrant sealing cover needs to be opened, only the movable jaw part 2 needs to be opened, the jaw 3 is expanded, after the movable jaw part 2 is bitten by a nut on the fire hydrant sealing cover, the movable jaw part 2 is closed, then the prying bar 4 is held by hand to apply force, the nut is rotated to open the sealing cover, in the force application process, the movable jaw part 2 can firmly press the nut on the fixed jaw part 1 due to the friction force of the nut on the movable jaw part 2, and therefore the jaw 3 cannot be automatically opened. After the sealing cover is opened, the fire hose is connected, then the square blind hole 6 at the lower end of the extension rod 5 or the regular pentagon blind hole 8 at the lower end of the extension rod 7 is used for being sleeved on the fire hydrant valve torsion bar, the square blind hole 6 or the regular pentagon blind hole 8 is specifically selected according to the shape of the fire hydrant valve torsion bar, then the two hands respectively grab the rear part of the pry bar 4 and the front part of the fixed jaw part 1 to rotate, and the valve is opened to take water.
When the height of the fire hydrant on the ground is high, the torsion bar of the fire hydrant valve is inconvenient to rotate by adopting the square blind hole 6 at the lower end of the extension rod 5 or the regular pentagonal blind hole 8 at the lower end of the extension rod 7, and the torsion bar of the fire hydrant valve is directly rotated by adopting the polygonal blind hole 13 on the bolt 12.
If meet the fire hydrant underground, then directly use the crow bar 4 to prize the lid on the bottom surface, then use square blind hole 6 or the regular pentagon blind hole 8 of extension rod 7 lower extreme of extension rod 5 lower extreme to cup joint on the fire hydrant valve torsion bar, specifically select square blind hole 6 or regular pentagon blind hole 8 according to the shape of fire hydrant valve torsion bar, then both hands grasp the crow bar 4 rear portion respectively and fixed 1 front portions of jaw portion rotate, open the valve and get the water.
The above embodiments are merely illustrative of the principles and effects of the present invention, and some embodiments in use, and are not intended to limit the invention; it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications belong to the protection scope of the present invention.
