Description
Technical field
The utility model relates to a kind of mounting or dismounting pipeline hand tools, specifically a kind of Telescopic handle pipe wrench.
Background technology
We know, pipe wrench is the indispensable instrument of various pipeline dismounting operation.At present, generally use GB8406-87 type pipe wrench, also have various Boost pipe tongs, as Chinese patent 98221359.X, 02213923.0 Boost pipe tongs etc.They are primarily of moving jaw, caliper, adjusting nut, clamp handle composition.Clamp handle adopts sleeve type structure, and be made up of sleeve pipe and Telescopic handle, afterburning pull bar can stretch in sleeve pipe.Above-mentioned pipe wrench is in order to light, and the sleeve pipe front end of clamp handle and caliper directly connect, and reduces the torsional strength of pipe wrench, easily occurs fracture.
Summary of the invention
Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art, and provide a kind of structure simple, cost is low, lightweight, and moment of torsion is large, can meet the Telescopic handle pipe wrench of various moment of torsion operation.
The technical scheme in the invention for solving the above technical problem is: a kind of Telescopic handle pipe wrench, it includes moving jaw, caliper, adjusting nut, clamp handle, described clamp handle includes sleeve pipe, flexible reinforcement handle, fixing stifled ring, fixing stifled ring is arranged on cannula end, stifled ring is scalable is arranged in sleeve pipe by fixing for flexible reinforcement handle, it is characterized in that: described caliper rear portion is provided with the externally threaded clamp handle joint of a band, be installed with a sleeve pipe in the sleeve pipe front end endoporus of described clamp handle and strengthen post; Described sleeve pipe is connected with clamp handle joint by a nut sleeve, and described nut sleeve front portion is connected with clamp handle joint screw thread, and rear portion and sleeve pipe are welded and fixed.
The anterior radial symmetric of described nut sleeve is provided with a pair screw, and coordinated with screw by jackscrew, nut sleeve and clamp handle joint are connected and fixed.Loosen to prevent radial rotating between nut sleeve and clamp handle joint.
The utility model adopts said structure, has set up the clamp handle joint of integrative-structure at caliper rear portion, has set up sleeve pipe and strengthen post in the endoporus of sleeve pipe front end; Sleeve pipe and caliper adopt nut sleeve to be connected and fixed, and substantially increase bonding strength and the torsional strength of caliper and sleeve pipe.Against existing technologies, the utility model is rational in infrastructure, and processing cost is low, and easy to use, reliable, lightweight, moment of torsion is large, can meet various stubborn apart from operation needs.

1. moving jaws, 2. caliper, 3. fixed teeth, 4. adjusting nut, 5. jackscrew, 6. nut sleeve in figure, 7. sleeve pipe strengthens post, 8. sleeve pipe, 9. fixing stifled ring, 10. flexible reinforcement handle.
Detailed description of the invention
As can be seen from Figure 1, a kind of Telescopic handle pipe wrench, it is provided with moving jaw 1, caliper 2, fixed teeth 3, adjusting nut 4, clamp handle etc.By rotating adjusting nut 4, moving jaw 1 can move forward and backward along clamp body slot, adjusting jaw size.Caliper 2 and clamp handle are Split type structure.Described clamp handle includes sleeve pipe 8, flexible reinforcement handle 10, fixing stifled ring 9 etc.Fixing stifled ring 9 is arranged on sleeve pipe 8 tail end, and sleeve pipe 8 endoporus is equipped with steel pipe type and stretches reinforcement handle 10, and flexible reinforcement handle 10 can stretch in casing tong delthyrium.Determination is conveniently stretched the length of reinforcement handle, and the fixing stifled ring 9 of cannula end is self-tightening type, can freely select clamp handle length.Above-mentioned composition structure belongs to prior art, repeats no more.
Feature of the present utility model is: described caliper 2 rear portion is provided with the externally threaded clamp handle joint of a band, clamp handle joint caliper 2 integrative-structure.Be installed with a sleeve pipe in the sleeve pipe 8 front end endoporus of described clamp handle and strengthen post 7; Described sleeve pipe 8 is connected with clamp handle joint by a nut sleeve 6.Specifically: described nut sleeve 6 is anterior to be fixedly connected with clamp handle joint screw thread, and the sleeve pipe 8 that band sleeve pipe strengthens post 7 inserts nut sleeve 6 rear portion endoporus, and nut sleeve 6 rear portion and sleeve pipe 8 outer wall are welded and fixed.As shown in Figure 2.Substantially increase bonding strength and and the torsional strength of caliper and sleeve pipe like this.
The utility model loosens for preventing radial rotating between nut sleeve 6 and clamp handle joint, and the anterior radial symmetric of described nut sleeve 6 is provided with a pair screw, is coordinated with screw by jackscrew 5, and nut sleeve 6 and clamp handle joint are connected and fixed.As shown in Figure 2 and Figure 3.
The utility model has set up the clamp handle joint of integrative-structure at caliper 2 rear portion, has set up sleeve pipe and strengthen post 7 in the endoporus of sleeve pipe 8 front end; Sleeve pipe and caliper adopt nut sleeve to be connected and fixed.Substantially increase bonding strength and the torsional strength of caliper and sleeve pipe.It is rational in infrastructure, and processing technology is simple, and processing cost is low, easy to use, reliable, lightweight, moment of torsion large, can meet various stubborn apart from operation needs.
