Description
Technical field
The present invention relates to the technical field of five metals hand-operated tools, specifically a kind of pipe wrench that can quick adjustment opening amount.
Background technology
Pipe wrench in the market is mostly made up of regular jaw, moving jaw, clamp handle body, adjusting nut etc., regular jaw and clamp handle body become one, the front end of clamp handle body is regular jaw, the V-shaped flank of tooth in inner side of regular jaw, the V-shaped flank of tooth of front end of moving jaw. Drive moving jaw to move change jaw opening amount size by adjusting nut and carry out work, it is widely used in clamping and the circular tubing workpiece of turn-knob. When use, rotate adjusting nut, nut, threaded engagement are rotated the movement of adjusting moving jaw, and the opening amount size of the relative regular jaw of moving jaw is changed, and clamp circular tubing workpiece.
In use need bimanualness, constantly rotate adjusting nut, repeatedly adjust jaw opening amount, therefore, governing speed is slow, wastes time and energy. Clamping tubing workpiece or pipe, in the time that pipe wrench jaw is stressed, due to the gap of nut, threaded engagement, make nut easily loosening, and skidding appears in jaw clamping, easy damaged surface of the work. In addition, the requirement of strength of regular jaw, moving jaw and clamp handle body is high, and its regular jaw and clamp handle body are integrated, so make pipe wrench volume large, weight is large. It uses inconvenient, and troublesome poeration, wastes time and energy, inefficiency.
Summary of the invention

Detailed description of the invention
As shown in the figure, a kind of pipe wrench that can quick adjustment opening amount, comprise regular jaw, moving jaw, pull body 1 and pull body handle 8, regular jaw is being pulled the inner side of body handle 8 front ends, moving jaw is being pulled a side of body 1 front end, on regular jaw and moving jaw, be respectively equipped with saw shape tooth, the wedge angle wire clamp angle of saw shape tooth is 7 °-9 °, on the anterior inner side of pulling body handle 8, be provided with helical teeth, pull body handle 8 and be provided with scale, there is through hole pulling a side on body 1, through hole direction is vertical with moving jaw, pulling body handle 8 enters and pulls 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 of pulling body handle 8 inner sides, the helical teeth of pulling 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, in centre bore, there is successively from top to bottom backing pin 5, spring 6 and ball 7, ball 7 is in macropore, there is radial direction through hole upper end at backing pin, backing pin 5 tops are in the slotted eye of pulling in body 1, pin 2 enters the hole of pulling on body 1 radial direction through hole through backing pin 5 upper ends, backing pin 5 with pull body 1 and be hinged by pin 2, there is an arc groove at ball 7 with pulling on body 1 groove walls phase-contact surface, the line of arc groove center and pin 2 center lines is parallel to pulls helical teeth top on body handle 8, on body, there is rivet 3 pulling of pin lower left, the angle forming 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 of pulling the arc groove in body 1 groove walls is less than ball 7 semicircle radians. be an inclined-plane pulling the right side in through hole on body 1, inclined-plane is from top to bottom 2.8 °-3.2 ° with the angle of pulling body handle 8, forms the end opening that is greater than suitable for reading of through hole.
Worm screw of the present invention when pulling helical teeth on body handle and engage, stirs worm screw rotation with finger, pulls body and moves pulling on body handle, and opening amount that can accurate adjustment jaw is adjusted and completely can be clamped pipe rotation.
In the time needing the opening amount of quick adjustment jaw, pull out worm screw left, backing pin upper end in worm screw is hinged on and pulls in body by pin, while 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 can fast moving pull body, make to pull body and are pulling on body handle on corresponding scale. And then worm screw is inwardly promoted to worm screw to the right, ball extrusion spring, backing pin continues to swing to the right, ball is entered in arc groove, spring stretches, and when the ball center of circle and the arc groove center of circle are when overlapping, spring reaches maximum extension amount, now worm screw is relatively stable, and worm screw is meshed with the helical teeth of pulling on body handle. At this moment can rotary worm finely tune the opening amount of jaw.
When use, pull out worm screw, make ball leave arc groove, worm screw departs from the helical teeth of pulling on body handle, and fast moving is pulled body to the position of pulling corresponding scale on body handle, then worm screw is inwardly promoted, ball is entered in arc groove, and worm screw is meshed with the helical teeth of pulling on body handle. At this moment rotary worm as required, the opening amount of accurate adjustment jaw.
Owing to there being saw shape tooth on regular jaw and moving jaw, the wedge angle wire clamp angle of saw shape tooth is 7 °-9 °, and can meet pipe wrench has enough clamping forces in the time of clamping pipe original state.
Describedly pull the right side in through hole on body and be an inclined-plane, inclined-plane is from top to bottom 2.8 °-3.2 ° with the angle of pulling body handle, forms the end opening that is greater than suitable for reading of through hole. Can ensure that like this pipe wrench, in the time of the twisting of clamping pipe, can produce the chucking power of strengthening gradually.
Pull helical teeth on body handle and be 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 of pulling on body handle, in the time pulling worm screw, can make worm screw depart from fast the helical teeth of pulling on body handle, make worm screw be swung away from helical teeth left with backing pin, the removable body of pulling. According to the scale of pulling on body handle, change and pull body in the position of pulling on body handle, the opening amount of energy rapid adjustment moving jaw and regular jaw.
The present invention is rational in infrastructure, easily manufactures, cost is low, lightweight, and its weight is 75 65 percent to percent of common pipe wrench weight, easy to use, simple to operate, time saving and energy saving, opening amount that can quick adjustment jaw, and operating efficiency is high.
