Abstract
The utility model relates to an inner pipe screwing-out device which is characterized by the inclusion of an inner screw rod and an outer sleeve, wherein the inner screw rod is sleeved in the outer sleeve; threads and an inner screw rod moving nut are arranged at the upper end of the inner screw rod, the inner screw rod moving nut can be rotated along the threads, and a circular truncated cone is formed at the lower end of the inner screw rod; the lower end of the outer sleeve is divided into a plurality of petaloid divisional plates, and an arris is formed outward at the end part of each divisional plate; and threads and an outer sleeve moving nut are arranged on the outer surface at the lower end of the outer sleeve, and the outer sleeve moving nut can be rotated along the threads. The diameter of the circular truncated cone at the lower end of the inner screw rod is greater than that of the upper end of the inner screw rod. An outer sleeve fixing nut is fixed at the upper end of the outer sleeve. A plurality of raised marks are formed lengthways on the outer surface of the circular truncated cone at the lower end of the inner screw rod. The inner pipe screwing-out device has the advantages of simple and reliable structure, convenience in operation, practicality and effectiveness, is easy to produce due to the simple structure, and is convenient to popularize and apply.
Description
Technical field
The utility model relates to a kind of pipeline maintenance instrument, especially a kind of device for screwing out that is used for interior disconnected pipe back-out.
Background technology
Finishing is for attractive in appearance now, the overwhelming majority is embedded in pipeline within the walls, and the tap of external screw-in or other joint, because the quality problems of tap or other joint, often run into the part that will screw in the nut seat within the walls and break in the situation of the inside in actual life when changing tap or other joint, will to break that pipe takes out smoothly be suitable difficulty otherwise destroy within the walls nut seat.
Disconnected pipe rewind down screw tap in patent CN201366693 discloses, the market is not seen as yet, and according to the principle of its explanation, the anticlockwise moment of torsion of generation may be big inadequately, thereby cause poor effect.
Patent CN2659645 disclose a kind of in disconnected pipe extractor, the market is not seen yet, and according to the principle of its explanation, by swivel bolt, promotes voussoir along moving on its inclined-plane, disconnected pipe until being close in, the power of fastening interlocking may be inadequately with it; In addition, when in taking out, breaking pipe, how interior disconnected pipe is taken off from interior disconnected pipe extractor, do not consider so that interior disconnected pipe extractor uses also repeatedly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, effective interior pipe device for screwing out is provided.
According to the technical scheme that the utility model provides, a kind of interior pipe device for screwing out, feature is: comprise inner screw and outer sleeve, inner screw is set in the outer sleeve; Be provided with screw thread and can be along the inner screw traveling nut of described screw thread rotation in the upper end of inner screw, the lower end of described inner screw forms a round platform; The lower end of described outer sleeve is divided into a plurality of petal-shaped cutting plates, and the end of cutting plate forms ansa laterally; Be provided with screw thread and can be at the lower end of described outer sleeve outer surface along the outer sleeve traveling nut of described screw thread rotation.
The diameter of described inner screw lower end round platform is greater than the diameter of inner screw upper end.
Be fixed with the outer sleeve hold-doun nut in the upper end of described outer sleeve.
The convex epirelief that some vertical settings are arranged on the outer surface of described inner screw lower end round platform.
The utility model is simple and reliable for structure, easy to operate, practicability and effectiveness, and its easy production simple in structure is easy to utilize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in the figure: interior pipe device for screwing out comprises inner screw 1, inner screw traveling nut 2, outer sleeve 3, outer sleeve hold-doun nut 4, outer sleeve traveling nut 5 etc.
The utility model comprises inner screw 1 and outer sleeve 3, and inner screw 1 is set in the outer sleeve 3; Be provided with screw thread and can be along the inner screw traveling nut 2 of described screw thread rotation in the upper end of inner screw 1, the lower end of described inner screw 1 forms a round platform, the convex epirelief that some vertical settings are arranged on the outer surface of round platform, the diameter of described inner screw 1 lower end round platform is than the big 4mm of diameter of inner screw 1 upper end; The thick 2mm of the barrel of described outer sleeve 3 is slit into a plurality of petal-shaped cutting plates in the lower end of distance outer sleeve 3 25mm punishment, and the end of cutting plate forms ansa laterally, and the thickness of described cutting plate is decremented to 1mm gradually by 2mm from top to bottom; Be provided with screw thread and can be at the lower end of described outer sleeve 3 outer surface along the outer sleeve traveling nut 5 of described screw thread rotation; Be fixed with outer sleeve hold-doun nut 4 at 10mm place, upper end apart from described outer sleeve 3.
The utility model in use, 10 ~ 20mm in the disconnected pipe in earlier the utility model being inserted, rotate inner screw traveling nut 2, make inner screw 1 along moving on the outer sleeve 3, because the bottom of inner screw 1 is a round platform, make the petal-shaped cutting plate of outer sleeve 3 bottoms strut, arrive to a certain degree, disconnected inside pipe wall in the ansa of cutting plate can thrust, rotate counterclockwise outer sleeve hold-doun nut 4 this moment, and disconnected pipe screws out it in will driving, and Not a hair of one's head shall be touched bad nut seat within the walls, again with new tap or other joint screw-in nut seat within the walls, to reach the purpose of repair and replacement.
After the taking-up, rotate inner screw traveling nut 2 earlier, inner screw 1 is moved down along outer sleeve 3, and then rotating jacket tube traveling nut 5, outer sleeve traveling nut 5 is moved from the top down, give the convergent force of petal-shaped cutting plate that struts, the cutting plate ansa is transferred to from interior disconnected inside pipe wall, interior disconnected pipe is taken off convenient use repeatedly of the present utility model.
