Abstract
The utility model relates to a pair of self-adjustable water pump pliers which belongs to the technical field of a pipeline installing tool. The utility model is composed of an upper plier body, a lower plier body, a plier shaft, a connecting rod, a pullback spring, a pressure spring, etc., wherein the connecting rod is bridged on handgrips of the upper and the lower plier bodies; the pullback spring is connected between the middle of the connecting rod and a front body part of the lower plier body. The pressure spring is arranged in the handgrip of the upper plier body, and the plier shaft is fixed on the lower plier body, and is arranged in a long slot on the upper plier body. The pullback spring pulls the connecting rod so that a jaw expands, and the plier shaft moves in the long slot to adjust the expanding size of the jaw. The end of the connecting rod is pressed by a sliding and locking pin, and the jaw is closed and tightly locked. The utility model has the advantages of easy adjustment for the expanding degree of the jaw, good closing and locking degree and long service life.
Description
The utility model relates to the structure of water pump pliers, belongs to pipelayer's tool technical field.
Existing water pump pliers is made of upper clamp, lower clamp, pincers axle screw, torsion spring, lock-screw etc., the jaw of upper clamp and handle are overall structure, the jaw of lower clamp and handle are for dividing body structure, the waist hole at handle middle part connects by lock-screw, and the front end of handle is hinged by the pinning and the upper jaw of torsion spring.Stir the handle of upper and lower caliper with hand, torsion spring will make jaw open, and lock-screw also moves along with opening in the waist hole of jaw, and jaw opens the length that size depends on the waist hole.Opening around pincers axle screw turns of jaw, the distribution of the clamping point of jaw folder secret service part becomes more and more unreasonable, the clamping degree variation with the increase of workpiece.The pincers handle Duan Weiyi inclined-plane in waist hole is set, and lock-screw pins jaw when the closure by the frictional force effect with the inclined-plane in the waist hole.Water pump pliers has been grown service time, owing to existing wearing and tearing to form the gap between lock-screw and the inclined-plane, can not make water pump pliers closed and locked, and might under the active force of torsion spring jaw be opened.
The purpose of this utility model is will provide a kind of jaw to open with closed to move the self-adjustable water pump pliers of control by upper and lower jaw opposing parallel.
The purpose of this utility model is to realize like this, the self-adjustable water pump pliers comprises upper clamp, lower clamp, pincers axle, safetied pin, it is characterized in that water pump pliers is provided with connecting rod, extension spring, stage clip, connecting rod is crossed on the handle portion of upper and lower caliper, the two ends of extension spring are connected to the middle part of connecting rod and the portion of predecessor of lower clamp, stage clip is arranged in the handle of upper clamp, the front end of stage clip is connected with connecting rod, upper clamp is provided with and clamps an elongated slot in the band circular arc that is complementary hole, fixedly connected with lower clamp in the middle part of pincers axle, two ends are arranged in the elongated slot of upper clamp.Open and closure of jaw is that the opposing parallel by upper and lower jaw moves, and when closed, the pincers axle is in the upper end of elongated slot, and when pincers spool were in the lower end of elongated slot, jaw opened and reaches at utmost.When jaw is closed, pull back safetied pin, make it be in the rear end in waist hole and push down connecting-rod head, prevent that extension spring pulling connecting rod from around the hinged elastic cylindrical pin rotation of connecting rod and lower clamp, guaranteeing that water pump pliers is in closure state.Break away from when promoting safetied pin and connecting-rod head forward, extension spring drags connecting rod and rotates around elastic cylindrical pin, and by moving behind the forward direction, jaw opens the pincers axle in elongated slot.Water pump pliers is when holding workpiece, because effect in the time of extension spring and stage clip, pincers axle with the size of holding workpiece in the jaw, are moved in elongated slot and can be found position, corresponding circular arc hole automatically, thereby realize the parallel mobile and clamping of upper and lower jaw, bite evenly distributes all the time.
The utility model novel and reasonable structure, the manufacturing is easy, and cost is low, and is easy for operation, and the bite of jaw holding workpiece is evenly distributed, and the position is relatively stable, clamping degree good, opens with closed convenient, flexible long service life.
Accompanying drawing is a structural representation of the present utility model, 1 upper clamp, 2 lower clamps, 3 pincers axles, 4 connecting rods, 5 extension springs, 6 stage clips, 7 safetied pins, 8 elastic cylindrical pins, 9 elongated slots among the figure.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
Upper clamp, lower clamp are the overall structure of jaw and handle disjunctor, and the elongated slot in band circular arc hole is set on the vice body of upper clamp, and the middle part of pincers axle is fixed on the lower clamp, and the two ends of pincers axle place elongated slot.In the handle of upper clamp stage clip is set, an end of stage clip is fixed on the handle, and the other end is connected with an end of connecting rod.The other end of connecting rod is connected on the lower clamp handle by elastic cylindrical pin, and tip designs becomes platform, for placing lock-screw locking in the waist hole.Between the middle part of connecting rod and the lower clamp predecessor extension spring is set.
