Abstract
Disclosed is a boost pipe wrench, which is composed of a moving wrench jaw (1), a wrench body (2), adjusting nuts (3), a fixing wrench jaw (4), a fixing wrench handle (5), a moving wrench handle (6). The utility model is characterized in that a spring ring (8) is arranged between the tail part of the fixing wrench handle (5) and a fixing cap (7), and the spring ring (8) presses the moving wrench handle (6) in radial direction. Therefore, the utility model which is in particular suitable for an oil field and pipelines installation and the maintenance has the advantages of simple structure, simple preparing process for components, low cost, easy assembly and flexible and convenient usage.
Description
The utility model relates to the hand tools of a kind of clamping and rotation round steel pipe class workpiece, especially a kind of Boost pipe tongs.
Pipe wrench is the hand tools of a kind of clamping and rotation round steel pipe class workpiece, through being usually used in connection or operations such as detaching pipelines and maintenance.At present, China generally uses and effect Boost pipe tongs preferably, and it is made up of moving jaw, regular jaw, adjusting nut, caliper, sleeve pipe and boosting-rod.By rotating adjusting nut, moving jaw moves forward and backward along caliper, the size of holding diameter with this adjustable pipe clamp; Establish the stifled ring in a location at the sleeve pipe afterbody, be provided with a jump ring in the stifled ring in location, jump ring radially clamps boosting-rod.Though this structure can be implemented the location to boosting-rod,, the strict complexity of processing technology of the stifled ring of jump ring and location, the processing cost height, and it is also very difficult in stifled ring jump ring to be installed, and make Boost pipe tongs assembling difficulty, cost up.
The purpose of this utility model just provides a kind of simple in structure, and processing technology of components is simple, and cost is low, and very easily assembling, Boost pipe tongs flexible and convenient to use.
The purpose of this utility model is achieved in that it is made up of moving jaw (1), caliper (2), adjusting nut (3), regular jaw (4), fixing pincers handle (5), adjustable clamp handle (6), it is characterized in that between the afterbody of fixing pincers handles (5) and locking cap (7) turn (8) being set, turn (8) radially connects adjustable clamp handle (6).Along with the axial stretching of adjustable clamp handle (6) in fixing pincers handles (5), produce frictional force between the outer wall of turn (8) and adjustable clamp handle (6), adjustable clamp handle (6) is located in fixing pincers handles (5) automatically at any time, flexible flexibly.
The utility model is compared the advantage that has with conventional art: owing to be provided with turn (8) between the afterbody of fixing pincers handles (5) and locking cap (7), turn (8) radially steps up adjustable clamp handle (6), along with the axial stretching of adjustable clamp handle (6) in fixing pincers handles (5), produce frictional force between the outer wall of turn (8) and adjustable clamp handle (6), thereby assurance adjustable clamp handle (6) is located at any time automatically in fixing pincers handles (5); Locking cap (7) and turn (8) can stop effectively that the oil stain and the silt that are bonded on the adjustable clamp handle (6) are brought in the fixing pincers handles (5), and adjustable clamp handle (6) can be stretched in fixing pincers handles (5) flexibly; And simple in structure, processing technology of components is simple, and cost is low, and very easily assembling is flexible and convenient to use.
Accompanying drawing:
Fig. 1 is a concrete structure schematic diagram of the present utility model;
The partial schematic diagram of Fig. 2 for connecting between afterbody, turn (8), locking cap (7) and the adjustable clamp handle (6) of fixing pincers handles (5).
1, moving jaw 2, caliper 3, adjusting nut 4, regular jaw
5, fixing pincers handle 6, adjustable clamp handle 7, locking cap 8, turn.
Below in conjunction with accompanying drawing the utility model is made concrete implementation:
In the drawings, present embodiment is by moving jaw (1), caliper (2), and adjusting nut (3), regular jaw (4), fixing pincers handle (5), adjustable clamp handle (6) is formed.Regular jaw (4) is fixed on the caliper (2) by rivet; Moving jaw (1) is contained in the caliper (2) by adjusting nut (3); The fixing pincers of tubular type handle (5) front end is fixing by screw thread and caliper (2); Adjustable clamp handle (6) is positioned at fixing pincers handle (5); Afterbody at fixing pincers handles (5) is equipped with a locking cap (7) by screw thread, to prevent that adjustable clamp handle (6) from all being pulled out; As shown in Figure 2, be provided with a turn (8) between the afterbody of fixing pincers handles (5) and locking cap (7), turn (8) radially connects adjustable clamp handle (6).
During use,, moving jaw (1) is moved forward and backward in caliper (2) by rotating adjusting nut (3), and the distance between change and the regular jaw (4), to satisfy the change of clamping diameter; Along with the axial pulling of adjustable clamp handle (6) in fixing pincers handles (5), produce frictional force between the outer wall of turn (8) and adjustable clamp handle (6), and assurance adjustable clamp handle (6) is located at any time automatically in fixing pincers handles (5).Simultaneously, locking cap (7) and turn (8) have stopped that effectively the oil stain and the silt that are bonded on the adjustable clamp handle (6) are brought in the fixing pincers handles (5).
