Description

Movable fire hydrant spanner

Technical Field

The utility model belongs to the technical field of the fire control technique and specifically relates to a movable fire hydrant spanner is related to.

Background

Fire hydrants are an important fire fighting infrastructure and their role in fighting fires is self evident. In order to facilitate fire extinguishing operation, the hexagonal bolt type valve switch of the fire hydrant is designed into a unified model so that a general fire-fighting wrench can be opened. However, the fire hydrant and the fire hydrant wrench have more manufacturers and have different sizes, so that the fire hydrant is not easy to open; and the outdoor fire hydrant is generally located in open-air places, is easy to rust, and in order to prevent the outer surface from rusting, the municipal administration department paints the surface of the fire hydrant every year, and the accumulated paint layer can change the size of the valve switch, so that the fire-fighting wrench cannot be sleeved on the fire hydrant, and is easy to slip even if the fire-fighting wrench can be sleeved on the fire hydrant, and the valve switch is difficult to open. And the paint coated on the surface is difficult to prevent the interior of the fire hydrant from rusting, and the rusty fire hydrant is extremely difficult to open due to the small torque of the hexagonal bolt type valve switch, so that the fire fighting efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a convenient movable fire hydrant spanner that cup joints at fire hydrant valve switch lateral wall to the not enough of prior art existence, avoids skidding, guarantees efficiency of fighting a fire.

In order to achieve the purpose, the utility model discloses the technical scheme that movable fire hydrant spanner adopted is:

the utility model provides an activity fire hydrant spanner, includes the handle bar, and the one end of handle bar is provided with the pressure head, and the pressure head lateral wall of handle bar dorsad is provided with the pawl, and the outside of pawl is provided with the chain, and the chain includes a plurality of inner plate, and the inner plate both ends are provided with outer chain plate, and the both ends of outer chain plate are articulated mutually with adjacent inner plate, are provided with on the outer chain plate and hang the round pin, and the one end of pressure head is seted up and is hung round pin complex couple, and the through-hole articulated with outer chain plate or inner plate is seted up to the other end of pressure head. The one end of chain is passed through the through-hole and is articulated in the one end of pressure head, hangs the round pin card and goes into to lock the chain after the couple at fire hydrant valve switch's lateral wall, and the phenomenon of skidding appears between pressure head and the fire hydrant valve switch lateral wall when the pawl avoids rotating the handle bar to light fire hydrant valve switch of opening guarantees the efficiency of fighting a fire.

Preferably, the hanging pin is a hinged shaft of the outer chain plate and the inner chain plate. The hinged shafts of the outer chain plate and the inner chain plate are extended to be used as hanging pins matched with the hooks, so that the chain structure can be simplified.

Preferably, the handle comprises a handle rod and is characterized by further comprising a sleeve, the sleeve is sleeved on the outer side of the handle rod in a sliding mode, a pentagonal jaw is arranged at the top of the sleeve, and a hexagonal jaw is arranged at the bottom of the sleeve. The sleeve is connected with the handle rod in a sliding mode, so that the torque can be conveniently adjusted when the handle is used, and the handle is more labor-saving.

Preferably, the cross sections of the pentagonal jaw and the hexagonal jaw are gradually converged from the outer opening end to the inner opening end. The size error of the pentagonal or hexagonal control rod of the fire hydrant valve, which is delivered from different manufacturers and batches in different production years, can be adapted.

Preferably, both sides of the handle rod are provided with grooves. The groove not only reduces the weight of the handle rod, but also improves the strength of the handle rod.

Preferably, the inverted teeth are bidirectional inverted teeth. The handle rod rotates clockwise or anticlockwise, and the pressure head and the outer side wall of the fire hydrant valve switch cannot slip.

Compared with the prior art, the utility model, have following advantage:

1. by utilizing the flexibility of the chain, the fire hydrant valve switch outer side wall is conveniently sleeved with the chain when in use, so that space is saved when the fire hydrant valve switch is not used, and the fire hydrant valve switch outer side wall is convenient to store;

2. according to the size of the outer contour of the fire hydrant valve switch, a hanging pin at a proper position is selected to be clamped into a hook, so that the chain is more attached to the outer side wall of the fire hydrant valve switch, and the fire hydrant valve switch is convenient to open or close;

3. the pawl is a bidirectional pawl. The handle bar rotates clockwise or anticlockwise, and the pressure head and the outer side wall of the fire hydrant valve switch cannot slip.
