Abstract
The utility model relates to a pair of pipe tongs which are a tool which is used for screwing and revolving a pipe in the process of the installation and the maintenance of a pipeline, in particular to a pair of self-lock pipe tongs. A tong body comprises three parts of a hook-shaped tongs jaw, the upper croccus of two connecting lugs which are mutually parallel, an outer arc jaw, a projecting connecting head, the lower croccus of a handle and a pin whose two heads are in flat potential. The pin is used as the circle center of two croccus jaws which can be arbitrarily opened or closed. The utility model has the functions of self-regulating and locking. The self-lock pipe tongs have the advantages of low cost, high work efficiency, strong adaptability and big clamping force, and are conveniently used and effectively avoid the jaws sliding in the process of working.
Description
The utility model relates to a kind of pipeline that is used for and installs or keep in repair instrument---the pipe vice, particularly self-locking type pipe wrench of twisting coil.
A kind of pipe vice commonly used, the last slit bamboo or chopped wood that is comprised jaw and screw mandrel by a slit bamboo or chopped wood is being connected the following slit bamboo or chopped wood that a slit bamboo or chopped wood comprises jaw and handle, and the adjusting nut of control jaw folding is equipped with in the junction, and two slit bamboo or chopped wood jaws are vertical substantially, and its folding is parallel.By the pipe vice of this structure, generally can twist coil, but its structure is comparatively complicated, fee of material, worker consume greatly, and jaw more easily produces and skids in especially working.
The purpose of this utility model is to provide that a kind of cost is low, work efficiency is high, carries with easy to use, and has automatic adjusting, the self-locking type pipe wrench of the function of auto lock.
Its solution is: caliper is combined by the last slit bamboo or chopped wood that comprises jaw and engaging lug, the following slit bamboo or chopped wood that comprises jaw, connector and handle and three parts of pivot pin.Wherein, the jaw of last slit bamboo or chopped wood adopts a hook-type (in order to the pipe location, and guaranteeing that upward the slit bamboo or chopped wood jaw has two bites to pipe), is furnished with tooth in the hook; The jaw of following slit bamboo or chopped wood adopts an outer arcuate (put in place in order to cooperate the slit bamboo or chopped wood pipe, and guarantee that jaw is corresponding with two bites of last slit bamboo or chopped wood jaw to a bite of pipe) with it adaptably, also is furnished with tooth on the outer arcuate; The both sides of last slit bamboo or chopped wood rear end have two engaging lugs that are parallel to each other, and the connector of a protrusion is arranged at following slit bamboo or chopped wood top, and connector adopts a pivot pin to be connected between two engaging lugs, and two slit bamboo or chopped wood jaws are the garden heart with the pivot pin, can launch arbitrarily or close up.
So at work, because the close fit of upper and lower slit bamboo or chopped wood can realize the pipe of different sizes (in the certain limit) is adjusted its suitable bite automatically, and 3 gesture of filling the span of a man's arms of formation is locked pipe naturally, yet is reached the purpose of twisting coil.
Further improvement of the utility model is: the hole of respectively adopting a gear formula on two engaging lugs; Respectively adopt the flat gesture of two symmetries at two of pivot pin; Adopt a securing member between pivot pin and the connector, give tightening.
So where necessary jaw is deployed on the constant angles, pushes away or an easy operation of drawing can realize by a relatively large margin adjusting adapting to usefulness in a big way by one.And its jaw transfers to any gear, all do not lose in the certain limit from conditioning function.
Existing pipe vice because the folding of its jaw is subjected to the control and the limit of regulating part, thereby in actual use, not only operation is not too convenient, and when pliers to turn-knob power that pipe produced greater than jaw during to the clamping force of pipe, jaw will produce and skid.This self-locking type pipe wrench fundamentally solves these problems, and its feature is: the power of being executed on its handle is directly proportional with clamping degree on its jaw, and promptly the application of force is big more on the handle, and the jaw place locks tightly more.So not only be convenient to operation but also can avoided jaw to skid effectively, and objectively can reduce the unnecessary wearing and tearing of jaw inner teeth gear again, thereby prolonged its service life.Advantage on the other hand of the present utility model is: product structure is simple, makes easily, and production can the saving of labor save material, reduces cost.
Accompanying drawing has been described an embodiment of the present utility model.
Fig. 1: the side view of self-locking type pipe wrench (including a kind of working condition).
Fig. 2: the vertical view of self-locking type pipe wrench.
Fig. 3, Fig. 4: two kinds of service behaviours of self-locking type pipe wrench and situation thereof.
(following contrast accompanying drawing) Fig. 1, Fig. 2: caliper is formed by last slit bamboo or chopped wood (1), following slit bamboo or chopped wood (2) and (3) three part groups of pivot pin.Last slit bamboo or chopped wood (1) is comprising a hook-type jaw (4) and two engaging lugs that are parallel to each other (5), following slit bamboo or chopped wood (2) is comprising the connector (7) and a handle (8) of an outer arcuate jaw (6), a protrusion, connector (7) is positioned between two engaging lugs (5), connected by pivot pin (3), two slit bamboo or chopped wood jaws (4), (6) are to be the garden heart with pivot pin (3), can launch arbitrarily or close up.The hole (9) that a gear formula is respectively arranged on two engaging lugs (5), the flat gesture (10) that two symmetries are respectively arranged at two of pivot pin (3) gives tightening (present embodiment has adopted a holding screw) with a securing member (11) between pivot pin (3) and the connector (7).With a pipe (12), reflected a kind of working condition of self-locking pipe among Fig. 1: formed one 3 gesture of filling the span of a man's arms pipe (12) locking, and it is big more to be that handle (8) is located the application of force, jaw (4), (6) are locked tightly more to pipe (12).Fig. 3: its suitable bite (being tool self-regulated place) can be adjusted automatically to the pipe (12) of different sizes (in the certain limit) in jaw (4), (6).Fig. 4: when jaw (4), (6) are deployed into certain angle (present embodiment be 90 degree), push away or an easy operation of drawing can realize jaw (4), (6) adjusting by a relatively large margin, can adapt to usefulness in a big way by handle (8).(arrow represents to push away, draw direction among the figure)
Claims (2)
1, a kind of pipe vice commonly used, the last slit bamboo or chopped wood that is comprised jaw and screw mandrel by a slit bamboo or chopped wood is being connected the following slit bamboo or chopped wood that a slit bamboo or chopped wood comprises jaw and handle: the adjusting nut of control jaw folding is equipped with in the junction, two slit bamboo or chopped wood jaws are vertical substantially, its folding is parallel, of the present utility model being characterised in that: the jaw (4) of going up slit bamboo or chopped wood (1) adopts a hook-type, is furnished with tooth in the hook; The jaw (6) of following slit bamboo or chopped wood (2) adopts an outer lonely shape with it adaptably, also is furnished with tooth on the outer lonely shape; The both sides of last slit bamboo or chopped wood (1) rear end have two engaging lugs that are parallel to each other (5), and the connector (7) of a protrusion is arranged at following slit bamboo or chopped wood (2) top, and connector (7) is positioned between two engaging lugs (5), adopt a pivot pin (3) to be connected; Two slit bamboo or chopped wood jaws (4), (6) are the garden heart with pivot pin (3), can launch arbitrarily or close and disturb.
