Abstract

The utility model relates to a connecting mechanism of a mechanical part, particularly, a dismountable fastening connecting mechanism, which comprises an outer pipe fitting, an inner pipe fitting which is assembled in the outer pipe fitting, a screw bolt, a screw cap and a flat washer. The utility model is characterized in that the hole diameter of a mounting hole on one side of the outer pipe fitting is larger than the hole diameter of a mounting hole on the same side of the inner pipe fitting; the hole diameters of the mounting holes on the other sides of the inner pipe fitting and the outer pipe fitting are same; a tubular lining sleeve is arranged on a screw rod on the bolt head end of the screw bolt; the external diameter of the lining sleeve is greater than the hole diameters of the mounting holes of the inner pipe fitting and is less than the hole diameters of the mounting holes of the outer pipe fitting; the length of the lining sleeve is a little bigger than the difference value of the external diameter of the outer pipe fitting and the external diameter of the inner pipe fitting; the lining sleeve is arranged in the mounting holes of the outer pipe fitting. The utility model has the advantages of simple structure, easy installation, the compact fitting fit of the pipe fittings, less possibility of looseness and displacement, the reduction of vibration and noise, processing time saving, cost saving and the improvement of assembling efficiency; besides, the surface treating layers of the pipe fittings are difficult to damage.

Description

Detachably be fastenedly connected mechanism
One, technical field
The utility model relates to a kind of bindiny mechanism of mechanical part, a kind of mechanism that detachably is fastenedly connected during especially pipe fitting connects.
Two, background technique
The present pipe fitting mechanism that removably connects normally is assemblied in interior pipe fitting in the outer tube member, and the mounting hole aperture unanimity on the inside and outside pipe fitting is passed the mounting hole of inside and outside pipe fitting with bolt, relies on plain washer, nut fastening.The fit tolerance of main outer pipe fitting internal diameter of the cooperation tightness between inside and outside pipe fitting and interior pipe fitting external diameter is determined, for pipe fitting in making inserts in the outer tube member easily, fit tolerance between pipe fitting is bigger, often cause between pipe fitting and can't compress, produce displacement, produce vibrations and noise in the using process, the too small then assembling difficulty of tolerance, the surface-treated layer of easy damaged pipe fitting.
Three, summary of the invention
The purpose of this utility model is intended to overcome the deficiencies in the prior art, provides a kind of simple in structure, easy to assembly, cooperates compactly between pipe fitting, is difficult for producing loosening and displacement, and shockproof and noise detachably is fastenedly connected mechanism in the use.
The utility model adopts such technological scheme: a kind of mechanism that detachably is fastenedly connected, include outer tube member, be assemblied in the interior pipe fitting in the outer tube member, bolt, nut, plain washer, the aperture of mounting hole that is characterized in being aforesaid outer tube member one side is greater than the aperture of interior pipe fitting homonymy mounting hole, interior pipe fitting is identical with the aperture of outer tube member opposite side mounting hole, the bolt head end screw rod of aforementioned bolt is provided with tubular liner, the external diameter of lining is greater than the aperture of the mounting hole of interior pipe fitting and less than the aperture of outer tube member mounting hole, the length of lining is slightly larger than the difference of the external diameter of the external diameter of outer tube member and interior pipe fitting, and lining places in the mounting hole of outer tube member.
Detachably be fastenedly connected mechanism by what the utility model provided; the connection of inside and outside pipe fitting compresses by the monolateral of the internal pipe fitting of lining sheathed on the bolt; eliminated the matching gap between inside and outside pipe fitting; simple in structure, easy to assembly; cooperate compact between pipe fitting; be difficult for producing loosening and displacement; thereby reduce vibrations and noise in using; omitted the apolegamy work between parts simultaneously; reduce the requirement on machining accuracy of parts; save process time and cost, improve efficiency of assembling, protected the surface-treated layer of parts injury-free.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: pipe fitting 5-outer tube member 6-lining 7-bolt in the 1-nut 2-plain washer 3-arc-shaped pad 4-
Five, embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.As shown in drawings, a kind of mechanism that detachably is fastenedly connected, include outer tube member 5, be assemblied in the interior pipe fitting 4 in the outer tube member, bolt 7, nut 1, plain washer 2, the aperture of mounting hole A that is characterized in being aforesaid outer tube member 5 one sides is greater than the aperture of interior pipe fitting 4 homonymy mounting hole B, interior pipe fitting 4 is identical with the aperture of outer tube member 5 opposite side mounting holes, the bolt head end screw rod of aforementioned bolt 7 is provided with tubular liner 6, the external diameter of lining 6 is greater than the aperture of the mounting hole B of interior pipe fitting 4 and less than the aperture of outer tube member 5 mounting hole A, the length of lining 6 is slightly larger than the difference of the external diameter of the external diameter of outer tube member 5 and interior pipe fitting 4, and lining 6 places in the mounting hole A of outer tube member 5.Also be provided with and the consistent arc-shaped pad 3 of outer tube member 5 external surface shape between plain washer 2 on the bolt 7 and the outer surface of outer tube member 5.The arc-shaped pad 3 that adopts is because its surface is consistent with outer tube member 5 external surface shape, and the two combination is tight, reduces friction, and can shield to the outer tube member surface layer.Lining 6 can also be integrated with the bolt head end screw rod of bolt 7, and promptly the bolt head end at bolt constitutes a round platform.
