Description

A kind of connecting pin
Technical field
The utility model belongs to mechanical design field, is specifically related to a kind of jockey.
Background technology
In traditional mechanical design field, especially in mechanism design, often use connecting pin, for the provisional connection of two parts, utilize the dial-out of connecting pin and insertion to realize the logical transition of motion or the break-make of connection.Usual employing be common bearing pin, band polished rod bolt or cylindrical bar, this type of connecting pin is generally used for common occasion, and connection request is low, has allowed radial clearance, and the insertion of connecting pin and transfer to and need special instrument to realize.For the use occasion that some are special, as: require that radial clearance is eliminated in junction, dial and insert easily, do not need to use specific purpose tool, staff can operate, and does not still reduce its performance after experiencing the plug of up to ten thousand times.Utilize traditional connecting pin to realize, then need to improve machining accuracy, improve the abrasion resistance of connecting pin and pin-and-hole, reduce the surface roughness of connecting pin and pin-and-hole, from machining angle, the cost paid is needed to be huge, simultaneously, traditional connecting pin cannot invariably need aid carry out dial insert, especially when the pin-and-hole on connected piece does not align, connecting pin may damage connecting hole or connecting pin when inserting, and repeatedly produces wearing and tearing after plug and causes junction radial clearance to increase.
Utility model content
The purpose of this utility model is: provide a kind of connecting pin, overcome that traditional connecting pin processing and manufacturing required precision is high, material wear ability good, surface roughness is high, can produce the deficiencies such as radial clearance in using, do not need aid to carry out plug simultaneously, conveniently repeatedly plug use.
The technical solution of the utility model is:
A kind of connecting pin, comprise shank 1 and nut 2, wherein shank is made up of wing bolt 101, packing ring 102, tapered sleeve 103, back-up ring 104, and packing ring 102, tapered sleeve 103 are placed on wing bolt 101 successively, and are fixed by back-up ring 104; Connected piece first 4 side has bellmouth first 401, connected piece second 3 side has bellmouth second 301, when bellmouth first 401 is coaxial with bellmouth second 301, two bellmouths can be combined into a bellmouth, and bellmouth size is identical with tapered sleeve 103 outer surface with tapering; Nut 2 is fixed on inside the bellmouth second 301 of connected piece second 3, and shank 1 through the bellmouth of connected piece first 4, connected piece second 3, is connected with nut 2 successively.
Described wing bolt 101 one end is provided with two and picks up the ears, and interlude is polished rod part, and the other end is the end of thread, and the end of thread and polished rod part are separated by circlip groove.
Described tapered sleeve 103 profile is frustum, and center has circular hole, and circle hole radius is greater than wing bolt 101 Major Diam and polished rod segment outer radius.
The bellmouth second 301 of described nut 2 center line and connected piece second 3 side is coaxially installed.
Described shank 1 is connected on connected piece by lanyard 5.
The beneficial effect that the utility model produces: a kind of connecting pin of the utility model, adopt taper sleeve type shank, can the bellmouth of self adaptation connected piece, connected piece auto-alignment can be made, to reduce when traditional connecting pin uses shank and the machining accuracy of connecting hole and the requirement of surface roughness, reduce processing and manufacturing cost.Simultaneously, wing bolt is adopted in the utility model shank, avoid the dependence to Pluging & pulling tool when traditional connecting pin uses, make to reach without the need to instrument in use, without the need to the demand of independent support equipment, back-up ring and packing ring is adopted to be fixed on wing bolt by tapered sleeve in shank, when making forward and reverse rotation wing bolt, realize insertion and the dial-out of shank easily, in use do not have parts to be scattered, shank lanyard is connected on connected piece, can not lose after extracting, the utility model structure is simple, easy realization, produce, use cost is low, can easily use under circumstances, higher universal value is had in machinery industry and relevant industries.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, refers to Fig. 1 to Fig. 2.
As depicted in figs. 1 and 2: a kind of connecting pin, comprise shank 1 and nut 2, wherein shank is made up of wing bolt 101, packing ring 102, tapered sleeve 103, back-up ring 104, and packing ring 102, tapered sleeve 103 are placed on wing bolt 101 successively, and are fixed by back-up ring 104; Connected piece first 4 side has bellmouth first 401, connected piece second 3 side has bellmouth second 301, when bellmouth first 401 is coaxial with bellmouth second 301, two bellmouths can be combined into a bellmouth, and bellmouth size is identical with tapered sleeve 103 outer surface with tapering; Nut 2 is plate nut, and inside the bellmouth second 301 being riveted on connected piece second 3, shank 1 through the bellmouth of connected piece first 4, connected piece second 3, is connected with nut 2 successively.
Described wing bolt 101 one end is provided with two and picks up the ears, and interlude is polished rod part, and the other end is the end of thread, and the end of thread and polished rod part are separated by circlip groove.
Described tapered sleeve 103 profile is frustum, and center has circular hole, and circle hole radius is greater than wing bolt 101 Major Diam and polished rod segment outer radius.
The bellmouth second 301 of described nut 2 center line and connected piece second 3 side is coaxially installed.
Described shank 1 is connected on connected piece by lanyard 5.
