Dismounting and mounting tool for tubular part

Abstract

The invention discloses a dismounting and mounting tool for a tubular part, and belongs to the field of manual tools. The dismounting and mounting tool comprises a propping rod, a sleeve and slips, wherein the sleeve coaxially sleeves the propping rod; one end of the propping rod is in a shape of a frustum; outer threads are formed on the outer sidewall of the middle part of the propping rod; theother end of the propping rod extends out of the sleeve; inner threads matched with the outer threads are formed in the inner wall of the sleeve; a plurality of through holes are formed in one end ofthe sleeve, and each through hole is movably equipped with one slip; one side surface of each slip is in contact with the frustum surface of one frustum-shaped end of the propping rod. According to the dismounting and mounting tool for the tubular part, the end, extending out of the sleeve, of the propping rod can be twisted to enable the propping rod to move toward the end, provided with the through holes, of the sleeve; the slips are pushed through the frustum surface of one frustum-shaped end of the propping rod until the slips are propped to the inner sidewall of the tubular part; and thenthe sleeve can be clamped through a clamping tool and then rotated, and thus the tubular part can be dismounted or mounted; and the damage to the outer sidewall of the tubular part is avoided.

Description

technical field [0001] The invention relates to the field of hand tools, in particular to a disassembly tool for tubular parts. Background technique [0002] Threaded connection is a very common connection method, which is widely used in the connection between various tubular parts. [0003] The connected part of the tubular part is usually provided with an internal thread or an external thread, which can be connected with an external thread or an internal thread on another part. When two tubular parts are connected or disconnected, The tubular parts need to be clamped by pipe wrench or other dismounting tools to make the two tubular parts rotate relative to each other. However, due to the structural limitations on the outer surface of some tubular parts, for example, some pipes are equipped with valves, it is inconvenient to use clamping tools to clamp the outer surface, and some tubular parts have higher requirements on the quality of the outer surface. During the holdin...
