Description

Fire hydrant spanner

Technical Field

The utility model relates to a fire-fighting equipment technical field especially relates to a fire hydrant spanner.

Background

In the fire-fighting engineering construction, the installation fire hydrant needs suitable instrument, generally with the screw of breakout tongs card chucking fire hydrant head, fire hydrant screw shape is the hexahedron, but because breakout tongs card simple structure, mismatch with fire hydrant screw shape, only several point contact fire hydrant screws when twisting, can destroy the lacquer of fire hydrant screw during the use, the life of fire hydrant screw has been reduced, the screw of fire hydrant head is twisted bad easily during the construction simultaneously, the spoilage reaches 7%, and the power that the breakout tongs card can exert is little, it is inconvenient to use, work efficiency is low, therefore, research and development a fire hydrant spanner is imperative.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model aims at providing a fire hydrant spanner can effectively solve installation fire hydrant in-process, the problem that the fire hydrant head screw spoilage is high and the installation effectiveness is low.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a fire hydrant spanner, including handle and spanner head, the spanner head is opened there is concave type opening, the outer wall periphery of spanner head is arc, spanner head lower part is connected with the handle upper end and is constituted a body structure, the spanner head includes first clamping part and second clamping part, first clamping part is squarely, fixed dress is on the handle below it, the fixed block that has the through-hole is opened in the positive and negative welding respectively of second clamping part one end, be equipped with the pivot through the through-hole on the fixed block, first clamping part one end has the shaft hole, the pivot penetrates the shaft hole, it is together articulated with second clamping part to articulate first clamping part, the inner wall of first clamping part and second clamping part constitutes the regular hexahedron body with fire hydrant head periphery matching with the opening.

The utility model has the advantages of simple and reasonable structure, novel unique effectively solves the installation fire hydrant in-process, the problem that fire hydrant head screw spoilage is high and installation effectiveness is low, labour saving and time saving, and is with low costs, carries, convenient to use, and resources are saved has good society and economic benefits.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, a fire hydrant spanner comprises a handle 1 and a spanner head 3, wherein the spanner head 3 is provided with a concave opening, the periphery of the outer wall of the spanner head 3 is arc-shaped, the lower part of the spanner head 3 is connected with the upper end of the handle 1 to form an integrated structure, the spanner head 3 comprises a first clamping part 4 and a second clamping part 5, the first clamping part 4 is square, the lower part of the first clamping part 4 is fixedly arranged on the handle 1, the front and the back of one end of the second clamping part 5 are respectively welded with a fixing block 6 with a through hole, a rotating shaft 7 is arranged on the fixing block 6 through the through hole, one end of the first clamping part 4 is provided with a shaft hole, the rotating shaft 7 penetrates into the shaft hole, the first clamping part 4 is hinged with the second clamping part 5, and the inner walls of the first clamping part 4 and the second clamping part 5 and the opening form a regular hexahedron shape matched with the.

The inner walls of the first clamping part 4 and the second clamping part 5 are in a sawtooth shape.

The fixed block 6 is square or round.

The handle 1 is connected with the internal thread at the upper part of the forcing rod 2 through external threads.

The stress application rod 2 is formed by connecting a plurality of hollow pipes in a sleeved mode.

When the fire hydrant needs to be screwed down, the stress application rod is connected to the handle in a threaded mode, the opening is opened, the second clamping portion is clamped on the periphery of the fire hydrant head 8 from the right side of the fire hydrant head, the stress application rod is held by a hand to rotate forwards, the first clamping portion rotates by taking the rotating shaft as the center, the first clamping portion and the second clamping portion are matched to clamp the fire hydrant head, the stress application rod is held by the hand to continue to rotate forwards so as to screw the fire hydrant head, and the wrench can be dismounted when the stress application rod rotates backwards after being screwed down; when the fire hydrant needs to be dismounted, the second clamping part is clamped at the periphery of the fire hydrant head from the left side of the fire hydrant head, the force applying rod is held by hand to rotate reversely, and the fire hydrant can be dismounted.

The utility model discloses utilize ingenious utilization lever principle, elongated stress application pole can increase the arm of force, has reduced intensity of labour, and fixed block on the second clamping part is connected through the pivot to first clamping part, and the spanner that relieves that like this can be quick, convenient to use has improved work efficiency, and during the use, five-sided contacts of spanner head and fire hydrant head, and area of contact is big, not fragile fire hydrant head. Therefore, the utility model discloses effectively solve installation fire hydrant in-process, the problem that fire hydrant head screw spoilage is high and the installation effectiveness is low, and is with low costs, has practiced thrift the resource, has good society and economic benefits.
