Description

Quick pipe tongs

Technical Field

The utility model belongs to the technical field of a hand tool's technique and specifically relates to a quick breakout tongs.

Background

The pipe tongs in the market at present are mostly composed of a fixed jaw, a movable jaw, a tong handle body, an adjusting nut and the like, work is carried out by rotating and adjusting the opening amount of the jaw through the matching of the nut and threads, and the pipe tongs are widely applied to clamping and twisting round pipe workpieces. When the adjustable clamp is used, the adjusting nut is rotated, and the movable jaw is adjusted to move, so that the opening amount of the movable jaw relative to the fixed jaw is changed, and a circular pipe workpiece is clamped. In the using process, the adjusting nut is continuously rotated by hands to adjust the opening amount of the jaw, so that time and labor are wasted, two points of the jaw of the pipe wrench are stressed when a workpiece is clamped, the jaw of the pipe wrench is easy to slip, and the surface of the workpiece is easily damaged.

Disclosure of Invention

The utility model aims at overcoming the defects of the prior art and providing a quick pipe wrench which has reasonable design, simple structure, easy manufacture and convenient use.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a quick pipe tongs, comprises activity keep silent, little rivet, torsional spring, big rivet, round pin axle, clamp plate, handle etc. its characterized in that: the handle front end is equipped with stationary jaw, big rivet hole and little round hole, the stalk portion is equipped with the round pin shaft hole, the afterbody is equipped with conical pointed tail, stationary jaw's profile of tooth is outer arc flank of involute, movable jaw front end inboard is equipped with the internal tooth face of V-arrangement, the afterbody is equipped with little rivet hole and big rivet hole, the afterbody left side is equipped with protruding structure, little rivet fixation is downthehole at movable jaw's little rivet, big rivet passes movable jaw and fixes the torsional spring in its inboard inslot, torsional spring one end is colluded in the little round hole on the handle, the other end colludes on little rivet. The pin shaft penetrates through the pressing plate to fix the pressing plate on the handle, the left upper end of the pressing plate is propped against the protruding structure of the movable jaw, and the pressing plate can rotate around the pin shaft.

The quick pipe wrench is characterized in that: when the right lower end of the pressing plate is pressed by a hand, under the action of a lever principle, the left upper end of the pressing plate extrudes the convex structure of the movable jaw, so that the movable jaw can rotate clockwise around the large rivet, the opening amount of the pipe wrench is rapidly increased, and at the moment, the torsion spring is subjected to torsion bending and stores energy; after the pipe tongs are sleeved on the workpiece, the torsion spring releases energy rapidly only by loosening the hand, so that the movable jaw is driven to close rapidly, and the purpose of rapidly clamping the workpiece is achieved. In addition, the utility model has the advantage that can realize one-hand operation, promptly: the handle is held by a single hand, and the opening amount can be quickly opened by pressing the pressing plate by a thumb.

The utility model relates to a rationally, simple structure, easy manufacturing, use, convenient operation, labour saving and time saving can quick centre gripping work piece, greatly reduced operator intensity of labour.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

FIG. 2 is a schematic view of the direction of force application.

The labels in the figure are: 1. the movable jaw comprises a movable jaw body, 2 small rivets, 3 torsional springs, 4 large rivets, 5 pin shafts, 6 pressing plates, 7 and handles.

Detailed Description

As shown in fig. 1: a quick pipe wrench, comprising: the adjustable jaw comprises a movable jaw 1, a small rivet 2, a torsion spring 3, a big rivet 4, a pin shaft 5, a pressing plate 6, a handle 7 and the like, and is characterized in that: 7 front ends of handle are equipped with fixed jaw, big rivet hole and little round hole, the stalk portion is equipped with the round pin shaft hole, the afterbody is equipped with conical pointed tail, fixed jaw's profile of tooth is outer arc involute flank of tooth, 1 front end inboard of adjustable jaw is equipped with the internal tooth face of V-arrangement, the afterbody is equipped with little rivet hole and big rivet hole, the afterbody left side is equipped with protruding structure, little rivet 2 is fixed in adjustable jaw 1's little rivet hole, big rivet 4 passes adjustable jaw 1 and fixes torsional spring 3 in its inboard inslot, 3 one end of torsional spring colludes in the little round hole on handle 7, the other end colludes on little rivet 2. The pin shaft 5 passes through the pressing plate 6 to be fixed on the handle 7, the left upper end of the pressing plate 6 is propped against the protruding structure of the movable jaw 1, and the pressing plate 6 can rotate around the pin shaft 5.

As shown in fig. 2: when the right lower end of the pressing plate 6 is pressed by a hand, under the action of a lever principle, the left upper end of the pressing plate 6 extrudes the convex structure of the movable jaw 1, so that the movable jaw 1 can rotate clockwise around the large rivet 4, the opening amount of the pipe wrench is rapidly increased, and the torsion spring 3 is subjected to torsion bending at the moment and stores energy; after the pipe tongs are sleeved on the workpiece, the torsion spring 3 releases energy rapidly only by loosening the hand, so that the movable jaw 1 is driven to close rapidly, and the purpose of rapidly clamping the workpiece is achieved. In addition, the utility model has the advantage that can realize one-hand operation, promptly: the handle 1 is held by a single hand, and the opening amount can be quickly opened by pressing the pressing plate 6 with the thumb.

To sum up, the utility model relates to a rationally, simple structure makes easily, uses, convenient operation, labour saving and time saving, but quick centre gripping work piece, greatly reduced operator intensity of labour. .
