Description
Technical field
The utility model relates to a kind of pipe fitting dismantling device, specifically a kind of tube intracavity clamping tool.
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:
Tube intracavity clamping tool described in the utility model comprises cross-articulation the first pivoted arm together and the second pivoted arm, described first pivoted arm and the second pivoted arm lower end are hinged with expansion board respectively, the upper end of the first pivoted arm and the second pivoted arm is provided with installing hole, screw rod is fitted with in described installing hole, one end of described screw rod is provided with handle, and the screw rod between the first pivoted arm and the second pivoted arm is provided with two expanding nuts by screw thread.
The lateral surface of described expansion board is cambered surface, this cambered surface is provided with the alveolus for increasing frictional force; The medial surface of expansion board is provided with axle bed, and described axle bed is provided with hinge, and the lower end of described first pivoted arm or the second pivoted arm is connected on hinge.
Owing to have employed said structure, this clamping tool structure 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 practical state of the utility model embodiment.
Fig. 2 is the schematic cross-section of expansion board.
Detailed description of the invention
As shown in Figure 1, tube intracavity clamping tool described in the utility model comprises cross-articulation the first pivoted arm 1 together and the second pivoted arm 2, first pivoted arm 1 and the second pivoted arm 2 and is jointly arranged on and is positioned on the axis in its stage casing; Described first pivoted arm 1 and the second pivoted arm 2 lower end are hinged with expansion board 3,4 respectively, the upper end of the first pivoted arm 1 and the second pivoted arm 2 is provided with installing hole, screw rod 5 is fitted with in described installing hole, one end of described screw rod 5 is provided with handle 6, and the screw rod 5 between the first pivoted arm 1 and the second pivoted arm 2 is provided with two expanding nuts 7,8 by screw thread.The upper end that the distance adjusted between two expanding nuts 7,8 just can promote the first pivoted arm 1 and the second pivoted arm 2 is expanded to both sides, also just drive the lower end of the first pivoted arm 1 and the second pivoted arm 2 and two expansion boards 3,4 to expand outwardly simultaneously, thus the inwall of itself and pipe fitting 11 is combined closely, now can pipe fitting 11 opposing nut 12 be rotated driving handle 6 with spanner clamping nut 12, realize the charge and discharge operations of nut.
As shown in Figure 2, the lateral surface of described expansion board 3,4 is cambered surface, this cambered surface is provided with the alveolus for increasing frictional force; The medial surface of expansion board 3,4 is provided with axle bed 9, and described axle bed 9 is provided with hinge 10, and the lower end of described first pivoted arm 1 or the second pivoted arm 2 is connected on hinge 10.This radial type structure can make expansion board 3,4 be close to the inwall of pipe fitting 11 in stressed all the time, reaches maximal friction.
