Description

Novel adjustable wrench

Technical Field

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

Background

Need suitable instrument to install the part in the fire-fighting engineering construction, but some parts are like fire hydrant and mechanical tee bend, it all has to be eight arriss types and size from 40~100mm, generally install with the pipe tongs, but because the pipe tongs does not match with fire hydrant and mechanical tee bend shape, only several point contact fire hydrant when twisting, the installation effectiveness is very low, and can destroy the lacquer of fire hydrant during the use, the life of fire hydrant has been reduced, damage the fire hydrant head easily during the construction simultaneously, the spoilage reaches 7%, it is inconvenient to use, low working efficiency, consequently, improvement and the innovation to current spanner are imperative.

SUMMERY OF THE UTILITY MODEL

To the problem mentioned above, for overcoming prior art's defect, the utility model aims at providing a novel adjustable spanner can effectively solve in the fire control installation, damages the part easily and the problem that installation effectiveness is low.

In order to achieve the purpose, the technical scheme of the utility model is, a novel adjustable spanner, including handle and plate body, have the screw thread on the handle outer peripheral face, the nut is in the same place through the screw thread soon with the handle, the plate body is open-ended arc, the one end welding is on nut one side, the other end welding has the last holding head that has first recess in the middle part of the plane down, go up the holding head and be in directly over the handle, the handle upper end is equipped with down the holding head corresponding with last holding head, be equipped with the second recess corresponding with first recess above the holding head down, the holding head is fixed at the handle up end by the connecting pin through second recess center pinhole down, the center of first recess, second recess is on same straight line.

The utility model has the advantages of simple and reasonable structure, it is novel unique, effectively solve in the fire control installation, the unmatched mounting tool is to the high and low problem of installation effectiveness of the spoilage that the part caused, 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 following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

The novel adjustable wrench comprises a handle and a plate body, wherein threads are arranged on the outer peripheral surface of the handle 2, a nut 4 and the handle 2 are screwed together through the threads, the plate body 1 is in an open arc shape, one end of the plate body is welded on one side of the nut 4, the other end of the plate body is welded with an upper clamping head 1-1 with a first groove 1-2 in the middle of the lower plane, the upper clamping head 1-1 is positioned right above the handle 2, a lower clamping head 3 corresponding to the upper clamping head 1-1 is arranged at the upper end of the handle 2, a second groove 3-1 corresponding to the first groove 1-2 is arranged on the lower clamping head 3, the lower clamping head 3 is fixed on the upper end surface of the handle 2 through a connecting pin 6 through a second groove center pin hole, and the centers of the first groove 1-2 and the second groove 3-1 are on the same straight line.

In order to ensure better implementation effect, the first groove 1-2 and the second groove 3-1 have the same structure and are opposite up and down.

The outer side surface of the second clamping head 3 is provided with a guide rod 5 which vertically faces downwards, a guide groove 5-1 is welded on the nut 4, and the guide rod 5 extends into the guide groove 5-1 and is used for ensuring that the relative position of the first clamping head 1-1 and the second clamping head 3 is unchanged in the rotating process.

The utility model discloses at concrete during operation, according to the difference of part size, manual rotatory nut, the position that makes the relative nut of handle changes, and then the distance between holding head and the lower holding head is gone up in the regulation, down in the guide bar on the holding head stretches into the guide way on the nut, the relative position that rotates in-process down holding head and last holding head can not change, it is just right to have guaranteed the parallel of two recesses, put into the edges and corners of part in the recess of holding head and lower holding head, or with two faces of part and last holding head and the contact of holding head down, hold the handle and install, if user's application of force is difficult, the steel pipe of usable scene, stretch into the handle and do the power application pole in the steel pipe, it is more laborsaving during the use.

The utility model discloses simple structure, low in production cost, convenient operation utilizes ingenious utilization lever principle, and elongated stress application pole can increase the arm of force, has reduced intensity of labour, has improved work efficiency, and spanner and part agree with each other, has reduced the wearing and tearing to the part, has prolonged the life of part, has good society and economic benefits.
