Abstract
The utility model relates to pipe tongs. The pipe tongs comprise a tongs body handle, horizontal shafts, a handle, a movable jaw, a fixed jaw, inserted teeth and a lightening hole. The screw joint mode is adopted for the tongs body handle and the handle, the handle can horizontally stretch inside the tongs body handle, the handle and the horizontal shafts are integrated, the fixed jaw is of a right angle shape, and the movable jaw is connected with the tongs body handle through the horizontal shafts. The pipe tongs are simple in structure, reasonable in stress distribution, flexible, and convenient to operate.
Description
Technical field
The utility model relates to the hand-operated tools technical field, in particular, relates to a kind of improved pipe wrench.
Technical background
Nut structure and pipe that common pipe wrench mostly is by the pipe wrench end position, and still this screw structure is used for a long time the curling phenomenon of screw thread can be taken place, and has had a strong impact on the quality of location, has brought inconvenience to production, and, calibrate during use and also divide trouble.The shortcoming that the tradition pipe wrench exists is: complex manufacturing, and the percent defective height, weight is big, the cost height, assembling is inconvenient, and easy tong.
Summary of the invention
At prior art the problems referred to above, the utility model provides a kind of pipe wrench, and it is simple that this pipe wrench has production technology, in light weight, convenience operation.
For this reason, the technical scheme that provides of the utility model is:
A kind of pipe wrench is characterized in that comprising pipe wrench caliper handle, trunnion axis, handle, moving jaw, regular jaw, inserted tooth, and lightening hole; Pipe wrench caliper handle and handle adopt the mode that is spirally connected, handle can level stretch in pipe wrench caliper handle, handle and trunnion axis are one, regular jaw is rectangular in shape, moving jaw is connected with pipe wrench caliper handle by trunnion axis, moving jaw and trunnion axis are slidingly connected, and moving jaw, regular jaw are provided with the pincers tooth.
As a kind of improvement of the present utility model, handle separates with pipe wrench caliper handle, can increase arm of force length, thereby alleviates operator's labour intensity.
As another kind of improvement the of the present utility model, trunnion axis is 2 two-way horizontal axles.
For making the utility model pipe wrench more convenient operation, pipe wrench caliper handle length is 400 millimeters.
As another kind of improvement the of the present utility model, inserted tooth forges through cast steel, and is furnished with the carbon steel knurled nut through Overheating Treatment.
As a kind of improvement of the present utility model, pipe wrench is aluminum alloy materials.
Compared with prior art have following advantage:
The pipe wrench of this structure is not only simple in structure, and stressed distribution is reasonable, flexible and convenient operation, and oppositely the flank of tooth is non-slip, is applicable in the clamping and turn of cylindrical work.Safety labor-saving can effectively improve operating efficiency, improves the reliability of operation.The handle body adopts seamless steel pipe, grips comfortable, firm light.In addition, pipe wrench of the present utility model can adopt split type forging, and technology is simple, the yield rate height, and quality is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is pipe wrench caliper handle in the accompanying drawing, and 2 is trunnion axis, and 3 is handle, and 4 is moving jaw, and 5 is regular jaw, and 6 are pincers teeth, 7, be lightening hole.
The specific embodiment
Embodiment 1
Reference is shown in Figure 1, and the utility model is further described below in conjunction with accompanying drawing, by accompanying drawing as can be known
The utility model comprises pipe wrench caliper handle 1, trunnion axis 2, handle 3, moving jaw 4, regular jaw 5, pincers tooth 6, lightening hole 7, regular jaw 5 and trunnion axis 2, pipe wrench caliper handle 1 is one, and regular jaw 5 is rectangular in shape, and regular jaw 5 and moving jaw 4 are provided with pincers tooth 6.
During use, mobile moving jaw 4, placing thing as for moving jaw 4, between the regular jaw 5, turning handle 3 makes moving jaw 4 relative motion on trunnion axis 2, regular jaw 5 and moving jaw 4 is clamped use object, rotation along with handle 3, stressed object receiving force is also bigger, thereby with the body auto lock, body rotates along with the rotation of handle 3.
Be with being appreciated that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
Above content be in conjunction with concrete preferred embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the those of ordinary skill under the utility model, under the prerequisite that does not break away from this utility model thinking, can also make simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
