Abstract
The utility model relates to a kind of dismantling device of pipe fitting nut, specifically a kind of nut dismounting tool for male element.Comprise hinge, symmetrically arranged first friction plate and the second friction plate, the eccentric position symmetry of described hinge is hinged with the first support bar and the second support bar, and the end of the first support bar and the second support bar is hinged on the first friction plate and the second friction plate respectively; The circle centre position of described hinge is fixedly connected with handle by connecting rod.This tool construction is simple, easy to use, grips pipe fitting from inner chamber, can avoid damaging outer wall during operation.
Description
Technical field
The utility model relates to a kind of dismantling device of pipe fitting nut, specifically a kind of nut dismounting tool for male element.
Background technology
When the parts such as the nut on existing dismounting pipe fitting, in order to fixed fitting, generally adopt the instrument such as spanner, pipe wrench, these instruments mostly exert a force at the outer wall of pipe fitting, when outer surface of pipe fittings entire body screw thread or when having other frangible portions, spanner, pipe wrench clamping body is adopted easily to cause screw thread to damage.
Summary of the invention
The utility model provides the tube intracavity clamping tool that a kind of structure is simple, easy to use, clamp from inner chamber, avoid outer wall to damage for solving the problem.
The technical scheme that the utility model adopts for technical solution problem is:
Nut dismounting tool for male element described in the utility model comprises hinge, symmetrically arranged first friction plate and the second friction plate, the eccentric position symmetry of described hinge is hinged with the first support bar and the second support bar, and the end of the first support bar and the second support bar is hinged on the first friction plate and the second friction plate respectively; The circle centre position of described hinge is fixedly connected with handle by connecting rod.
Described first support bar, between the second support bar and hinge, be provided with return spring.
Owing to have employed said structure, this tool construction is simple, easy to use, grips pipe fitting from inner chamber, can avoid damaging outer wall during operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the using state of the utility model embodiment.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2, nut dismounting tool for male element described in the utility model comprises hinge 1, symmetrically arranged first friction plate 2 and the second friction plate 3, the eccentric position symmetry of described hinge 1 is hinged with the first support bar 4 and the second support bar 5, and two support bars can be deflected around hinge 1; The end of the first support bar 4 and the second support bar 5 is hinged on the first friction plate 2 and the second friction plate 3 respectively; The circle centre position of described hinge 1 is fixedly connected with handle 7 by connecting rod 6.
During use, as shown in Figure 1 the first friction plate 2 and the second friction plate 3 symmetry are put in the inner chamber of pipe fitting 9, rotate hinge 1 by the handle 7 of pipe fitting outside, promote support bar and friction plate is pressed on pipe fitting inner wall, now with spanner counter-rotation nut 10.
In addition, return spring 8 is provided with between described first support bar 4, second support bar 5 and hinge 1.Return spring 8 can adopt torsion spring, also can adopt normal spiral tubular type spring.Return spring 8 can apply a less initial force to support bar, by friction plate by being pressed on pipe fitting inner wall, avoids pipe fitting to come off.
Claims (2)
1. for the nut dismounting tool of male element, comprise hinge (1), symmetrically arranged first friction plate (2) and the second friction plate (3), it is characterized in that: the eccentric position symmetry of described hinge (1) is hinged with the first support bar (4) and the second support bar (5), the end of the first support bar (4) and the second support bar (5) is hinged on the first friction plate (2) and the second friction plate (3) respectively; The circle centre position of described hinge (1) is fixedly connected with handle (7) by connecting rod (6).
