Detailed description of the invention
As shown in the figure, a kind of can the pipe wrench of quick adjustment opening amount, comprise regular jaw, moving jaw, pull body 1 and pull body handle 8, the inner side of body handle 8 front end pulled by regular jaw, moving jaw is pulling the side of body 1 front end, regular jaw and moving jaw are respectively equipped with saw shape tooth, the wedge angle wire clamp angle of saw shape tooth is 7 °-9 °, the front inner pulling body handle 8 is provided with helical teeth, pull body handle 8 and be provided with scale, there is through hole pulling side on body 1, through hole direction is vertical with moving jaw, pull body handle 8 to enter and pull in body 1 through hole, pull body 1 pull on body handle 8 removable, be provided with groove pulling on body 1, the bottom of groove axially communicates with through hole, worm screw 4 is installed in groove, worm screw 4 is meshed with the helical teeth pulled inside body handle 8, the helical teeth pulled on body handle is stepped tooth, the spiral angle of helical teeth is identical with the spiral angle of worm screw, direction of rotation is contrary, its spiral angle is 7.2 °-7.4 °, the centre bore of worm screw 4 is shoulder hole, backing pin 5 is had successively from top to bottom in centre bore, spring 6 and ball 7, ball 7 is in macropore, radial direction through hole is had in the upper end of backing pin, backing pin 5 top is pulling in the slotted eye in body 1, pin 2 enters pulls the radial direction through hole of the hole on body 1 through backing pin 5 upper end, backing pin 5 with pull body 1 and be hinged by pin 2, an arc groove is had with pulling on body 1 groove walls phase-contact surface at ball 7, the line of arc groove center and pin 2 center line is parallel to pulls helical teeth top on body handle 8, rivet 3 is had pulling on body of pin lower left, the angle formed between the line at the line of pin and rivet and pin and arc groove center is 40 °-42 °, become the maximum pendulum angle of backing pin in worm screw.The radian pulling the arc groove in body 1 groove walls is less than ball 7 semicircle radian.Be an inclined-plane pulling the right side on body 1 in through hole, inclined-plane is from top to bottom 2.8 °-3.2 ° with the angle pulling body handle 8, forms the suitable for reading of through hole and is greater than end opening.
When worm screw of the present utility model engages with the helical teeth pulled on body handle, stir worm screw with finger and rotate, pull body pulling on body handle and move, can the opening amount of accurate adjustment jaw, adjust the complete pipe that can clamp and rotate.
When needing the opening amount of quick adjustment jaw, namely worm screw is pulled out left, backing pin upper end in worm screw by pin-hinges pulling in body, when pulling worm screw, backing pin swings left, ball departs from arc groove Compress Spring, when ball is rolled in the plane of groove walls, worm screw and helical teeth start to depart from, spring in worm screw centre bore is under pressure, and spring reaches maximum compression degree, when backing pin continues to swing to 40 ° of-42 ° of angles, backing pin is blocked by rivet, worm screw and helical teeth depart from completely, now movement can pull body fast, make to pull body and to pull on body handle on corresponding scale.And then namely worm screw is inwardly promoted worm screw to the right, ball extrusion spring, backing pin continues to swing to the right, ball is made to enter in arc groove, spring stretches, when the ball center of circle is overlapping with the arc groove center of circle, spring reaches maximum extension amount, now worm screw is relatively stable, and worm screw is meshed with the helical teeth pulled on body handle.At this moment the opening amount of finely tuning jaw can be carried out by rotary worm.
During use, pull out worm screw, make ball leave arc groove, worm screw departs from the helical teeth pulled on body handle, moves fast and pulls body to the position of pulling corresponding scale on body handle, more inwardly promoted by worm screw, make ball enter in arc groove, worm screw is meshed with the helical teeth pulled on body handle.At this moment rotary worm as required, the opening amount of accurate adjustment jaw.
Owing to regular jaw and moving jaw there being saw shape tooth, the wedge angle wire clamp angle of saw shape tooth is 7 °-9 °, and can meet pipe wrench has enough clamping forces when clamping pipe original state.
Described right side of pulling on body in through hole is an inclined-plane, and inclined-plane is from top to bottom 2.8 °-3.2 ° with the angle pulling body handle, forms the suitable for reading of through hole and is greater than end opening.Can ensure that pipe wrench is when clamping pipe twisting, can produce the chucking power strengthened gradually like this.
Pulling helical teeth on body handle is stepped tooth, the spiral angle of helical teeth is identical with the spiral angle of worm screw, direction of rotation is contrary, spiral angle is 7.2 °-7.4 °, worm screw is meshed with the helical teeth pulled on body handle, when pulling worm screw, worm screw can be made to depart from the helical teeth pulled on body handle fast, make worm screw be swung away from helical teeth left with backing pin, removablely pull body.According to the scale pulled on body handle, change is pulled body and is being pulled the position on body handle, the opening amount of energy rapid adjustment moving jaw and regular jaw.
The utility model is rational in infrastructure, easily manufactures, cost is low, lightweight, and its weight is seven ten five 60 five to percent percent of common pipe wrench weight, easy to use, simple to operate, time saving and energy saving, can the opening amount of quick adjustment jaw, and operating efficiency is high.
