Description
Technical field
The utility model relates to a kind of pipe fitting dismantling device, specifically inner chamber expansion jaw type pipe fitting dismantling device.
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:
Inner chamber described in the utility model expansion jaw type pipe fitting dismantling device comprises by the first hinge cross-articulation the first pivoted arm together and the second pivoted arm, and described first pivoted arm and the second pivoted arm lower end are hinged with expansion board respectively; With the internal thread hole that radial direction is arranged on described first hinge, by threaded engagement, screw rod is installed in this internal thread hole, the lower end of described screw rod is fixedly installed anticreep rule, screw rod between anticreep rule and the first hinge is hinged with the second hinge, described second hinge is vertical with screw rod to be arranged, and the two ends of support bar are hinged on the second hinge and expansion board respectively.
Described first hinge is arranged on the stage casing of the first pivoted arm and the second pivoted arm, and the upper end thereof that the first hinge is arranged on the first pivoted arm has handle.
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, described axle bed is provided with expansion board hinge, and lower end and the support bar of described first pivoted arm or the second pivoted arm are connected on expansion board hinge.
Owing to have employed said structure, this dismantling device 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 A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, inner chamber expansion jaw type pipe fitting dismantling device described in the utility model comprises by the first hinge 5 cross-articulation the first pivoted arm 1 and the second pivoted arm 2 together, and described first pivoted arm 1 and the second pivoted arm 2 lower end are hinged with expansion board 3,4 respectively; With the internal thread hole that radial direction is arranged on described first hinge 5, by threaded engagement, screw rod 6 is installed in this internal thread hole, the lower end of described screw rod 6 is fixedly installed anticreep rule 8, screw rod 6 between anticreep rule 8 and the first hinge 5 is hinged with the second hinge 7, described second hinge 7 is vertical with screw rod 6 to be arranged, and the two ends of support bar 9,10 are hinged on the second hinge 7 and expansion board 3,4 respectively.First pivoted arm 1, second pivoted arm 2 and support bar 9,10 form hinged parallelogram lever structure, rotary screw 6 can change the distance between the first hinge 5 and the second hinge 7, thus makes expansion board 3,4 produce the action expanding outwardly or inwardly shrink.When expansion board 3,4 expands outwardly and the inwall of pipe fitting 14 combine closely, pipe fitting is fixed, is convenient to the operation such as dismounting nut on pipe fitting further.
As shown in Figure 1 and Figure 2, described first hinge 5 is arranged on the stage casing of the first pivoted arm 1 and the second pivoted arm 2, and the upper end thereof that the first hinge 5 is arranged on the first pivoted arm 1 has handle 11,12.Handle 11,12 can 90-degree rotation, is convenient to hand-held or rotates pipe fitting.
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, described axle bed is provided with expansion board hinge 13, and lower end and the support bar 9,10 of described first pivoted arm 1 or the second pivoted arm 2 are connected on expansion board hinge 13.Can ensure that the outer surface of expansion board 3,4 is parallel with pipe fitting inner wall all the time like this, keep maximal friction.
