Abstract
The utility model relates to a kind of for screwing or unscrewing the tool of the adjustable pipe clamp clamp force of joint for pipe.Because clamping force crosses ambassador's pipe flattening deformation, failure when it is for thin-walled tube docking rotation, enough enclasping forces can be provided.Its technical solution is: the upper/lower terminal of convex spring shim described in the tool is flat, middle section is circular arc convex, the upper/lower terminal of convex spring shim is screwed on the square through hole inner wall of pipe wrench shank body, and convex spring shim middle section is in close contact when pipe wrench works with adjusting nut;Adjusting nut is placed in the square through hole of pipe wrench shank body, and in the hole of one end insertion tube clamp handle body of adjustable clamp head thread bar, rotating adjusting nut moves to the appropriate position adjustable clamp head thread bar.The utility model adjusts pipe wrench clamp clamp force by convex spring shim, achievees the purpose that the contour structures that will not damage thin-wall tube, can extend the service life of pipe, easy for installation.
Description
Technical field
The utility model relates to a kind of for screwing or unscrewing the tool of the adjustable pipe clamp clamp force of joint for pipe, belong to
Machinery tool.
Background technique
Pipe wrench is a kind of machine tool for screwing or unscrewing pipe fitting.It is to change opening for pipe wrench by stirring adjusting nut
Mouthful, the appearance face contact of two working faces and pipe.The contact force of adjusting nut and the pipe wrench shank body box left side can change pipe
The size of two working faces and outer tube surface contact force of pincers, this power is very rambunctious in practical operation.To thin-walled
, may be excessive due to the clamping force of application when pipe work, cause thin-wall tube to cause flattening deformation, failure because direct stress is excessive
The case where.For this purpose, the utility model proposes a kind of tools of adjustable pipe clamp clamp force.
Summary of the invention
The purpose of this utility model is: in order to during mounting and dismounting pipe thickness different pipe, for thin
Clamping force when wall pipe will not be because of rotation is excessive and makes pipe flattening deformation, failure, can then provide foot for heavy wall pipe
Enough enclasping forces will not cause slipping phenomenon because clamping force is too small.
In order to achieve the above object, the utility model uses a kind of following technical scheme: work of adjustable pipe clamp clamp force
Tool is by movable binding clip, convex spring shim, adjusting nut, pipe wrench shank body, screw composition, it is characterized in that: this tool is by a pair
Convex spring shim composition, convex spring shim is identical as the square through hole inner wall shape size of pipe wrench shank body, convex spring pad
Piece upper/lower terminal is flat, and middle section is circular arc convex, and the upper/lower terminal of convex spring shim is screwed
On the square through hole inner wall of pipe wrench shank body, the intermediate convex section of convex spring shim is close with adjusting nut when pipe wrench works
Contact;It is specific to use: first threaded bore to be carried out on the square through hole inner wall of pipe wrench shank body, then by the way of screw connection
Carry out installation fixation.Bump part on gasket is main contact action point, is arranged on the position contacted with adjusting nut.Pipe
Pincers are when screwing pipe or being unscrewed, since the effect of power can make the raised position of adjusting nut and convex spring shim tight
Contiguity touching, in the case where needing to increase clamping force, adjusting nut can closely oppress the male portion for the spring shim being in contact with it
Point, spring shim is since compression can generate elastic strain, and the adaptability to changes of generation can react on pipe wrench, to increase the folder of pipe wrench
Clamp force;In the case where clamping force is just enough, the male portion gentle touchdown of adjusting nut and spring shim, spring shim is not
The adaptability to changes for generating or generating subtle elastic strain, and generate then very little, to will not additionally increase the clamping force of pipe wrench.
The beneficial effects of the utility model are: the elastic strain power that (1) is generated by convex spring shim by compression
It acts on to achieve the purpose that adjust Friction spanner for pipe clamping force;(2) shape and structure that will not damage thin-wall tube, not will cause pipe
Flattening deformation, failure;(3) service life of pipe can be extended;(4) tool construction of this adjustable pipe clamp clamp force is simple,
It is easy to make, it is at low cost, it is easy for installation.
Detailed description of the invention
Fig. 1 is the installation diagram of the utility model adjustable pipe clamp clamp force tool
Fig. 2 is the tool of the utility model adjustable pipe clamp clamp force and the partial structural diagram of pipe wrench
Fig. 3 is the installation cross-sectional view of the tool of this adjustable pipe clamp clamp force
Fig. 4 is the structure chart of the convex spring shim 2 in the tool of this adjustable pipe clamp clamp force
In figure: 1. movable binding clips, 2. convex spring shims, 3. adjusting nuts, 4. pipe wrench shank bodies, 5. screws.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 3, the convex spring shim 2 that Friction spanner for pipe clamping force tool is adjusted is a pair, by two shape phases
Same convex spring shim composition, two convex spring shims are in a symmetrical arrangement, upper and lower ends screw 5 and pipe wrench shank body 4
Square through hole inner wall be connected.As shown in Figure 2, adjusting nut 3 is put into the square through hole of pipe wrench shank body 4, movable 1 screw thread of binding clip
In the hole of bar one end insertion tube clamp handle body 4, and it is directed at the threaded hole of adjusting nut 3, rotating adjusting nut 3 makes movable binding clip 1
Threaded rod moves to the appropriate position.When using pipe wrench, movable binding clip 1 is by external force, due to adjusting nut 3 and movable binding clip
1 is is threadedly coupled, and adjusting nut 3 is also by same external force, adjusting nut 3 and adjustable pipe clamp under external force
The convex spring shim 2 of clamp force tool is in close contact.When the pipe acted on is thick-walled pipe, folder required for rotation thick-walled pipe
When clamp force is inadequate, adjusting nut 3 can compress the male portion of convex spring shim 2, convex spring shim due to being compressed and
Elastic strain is generated, the corresponding adaptability to changes generated will increase the clamping force of pipe wrench, so as to reach required for rotation thick-walled pipe
Clamping force size.When the pipe acted on is thin-wall tube, clamping force required for thin-wall tube is rotated in just rotation enough
In the case where pipe, since under external force, adjusting nut 3 and 2 gentle touchdown of convex spring shim, convex spring shim are not produced
The raw or adaptability to changes that generates subtle elastic strain, and generate then very little, thus will not additionally increase the clamping force of pipe wrench, it is thin
Wall pipe will not be damaged since clamping force is excessive.
