Abstract
The utility model discloses a fast connecting lockpin which comprises a spiral mandrel, an internal screw thread sleeve and at least three roller balls, wherein the spiral mandrel comprises a screw handle, a male screw thread section and a stepped shaft section which comprises a big shaft diameter section and a small shaft diameter section. The outer diameter of the internal screw thread sleeve and a bolt hole are in slide fit; the internal screw thread sleeve comprises a stepped hole; the upper section of the stepped hole is a female screw thread section which is matched with the male screw thread of the mandrel; the middle section of the stepped hole is a big hole section which is in the slide fit with a big diameter section of the mandrel; the lower section of the stepped hole is a small hole section which is matched with a small diameter section. At least three roller ball holes are uniformly distributed at the cross section of the big hole section along the circumference; one roller ball is arranged in each of the roller ball holes. When the roller balls are positioned at the big diameter section of the mandrel, the utility model is projected out of the excircle of the internal screw thread sleeve; when the roller balls are positioned at the small diameter section, the utility model retracts in the excircle of the internal screw thread sleeve. One seal groove is respectively arranged in the excircle of the internal screw thread sleeve and the upper plane of the roller ball holes; an elastic sealing ring is arranged in the seal grooves. When the utility model is connected with the parts without tools, the utility model can be fastened by that the utility model is inserted in the bolt hole and the screw handle is screwed, and the utility model can be drawn out by loosening the screw handle.
Description
Technical field
The utility model relates to a kind of connection fastening piece, particularly a kind of fastening piece that can connect fast or dismantle.
Background technique
The connection of traditional mechanical parts is with screw bolt and nut the structure of closing to be connected, and this method is to be fine fully in the ordinary course of things.But in the bolt or the very narrow and small occasion of nut surrounding space of some connected components, spanner insufficient space often makes not only difficulty, but also time-consuming of connection work; In addition, under the situation of the frequent dismounting of needs, for example clamping work pieces is processed on the worktable of lathe, and during another part of dismounting and change, frequent mounting or dismounting also are the work of a trouble concerning the workman to completion of processing again.So a kind of fastening piece that can connect fast or dismantle of people's demand can come out.
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, easy to operate fastening piece that can connect fast or dismantle-connect fast lock pin is provided.
Above-mentioned purpose adopts following technological scheme just can realize: the quick connection lock pin of the technical program comprises:
A spiral mandrel, it comprises that of being positioned at the upper end revolves handle, and revolves a mandrel linking together, and the stage casing of mandrel comprises one section external screw thread, be connected with a step shaft part below the male threaded section, the step shaft part comprises top an enlarged diameter section and a following reduced diameter section;
An inner screw sheath, the bolt hole sliding fit of its external diameter and institute's connected component, it comprises a step hole, the epimere of step hole is a female thread section that cooperates with external screw thread on the above-mentioned spiral mandrel, its stage casing is the macropore section of an enlarged diameter section sliding fit in the step shaft part with the spiral mandrel, and its hypomere is the aperture section of a reduced diameter section sliding fit in the step shaft part with the spiral mandrel; Circumference is provided with at least 3 ball holes in the middle cross section upper edge of above-mentioned macropore section; Upper limb at this ball hole is provided with a seal groove;
Above-mentioned spiral mandrel is assemblied in the inner screw sheath, and,
Have 3 balls in the ball hole that is contained in inner screw sheath at least, the diameter of each ball should satisfy following condition: its diameter and ball hole sliding fit, and when ball is arranged in the enlarged diameter section of step section of spiral mandrel, protrude in the cylindrical of inner screw sheath, when ball is arranged in the reduced diameter section of step section of spiral mandrel, be retracted within the cylindrical of inner screw sheath;
An elastic seal ring is contained in the seal groove of inner screw sheath.
This using method that connects fast lock pin is: during connected component, lock pin is inserted in the bolt hole of preparing two parts connecting, turn spiral mandrel revolve handle, make axially motion down of helix core, inner screw sheath drove ball and moved up this moment.When ball moved to enlarged diameter section in the step shaft part of spiral mandrel, ball was ejected the cylindrical of inner screw sheath by this enlarged diameter section and presses to the lower plane of following part thereupon, till two parts are compressed; During the dismounting part, handle is revolved in counterrotating, helix core is axially gone up to be moved, and inner screw sheath drive ball oppositely moves, leave a following part, when ball is arranged in the reduced diameter section of step shaft part of spiral mandrel, be withdrawn into because of ball within the cylindrical of inner screw sheath, so lock pin can be extracted from the hole.
As can be seen, the utility model has the advantages that structure is very simple, install and remove very conveniently, do not need any instrument, it is little or install and remove frequent occasion to be particularly useful for the spanner space.
In order to make the utility model more clear, it is described in further detail below by drawings and Examples.
