Abstract
The utility model relates to the technology field of check bolts, which is a loose-preventing unlock bolt with cone pin and in friction-locking type. The characteristic lies in that the external screw rod (1) is equipped with external thread (2), internal thread (12), sliding hole (13), pin hole (10) and pilot hole (14), connecting the external hexagon bolt head (3). The internal screw rod (4) is provided with the thread of the internal screw rod (15) and tip (16), connecting the internal hexagon bolt head(7); external screw rod. The pin hole (10) on the external screw rod is internally connected with the cone pin (5) and spring (9) and engages with the tip (16) on the internal screw rod(4). Wind up the internal screw rod (4) tightly, push out the cone pin (5) and lock the connecting piece. The utility model will not be broken off easily, with flexible movement, reliable locking and unlocking performances and wide applicable scope.
Description
Technical field
A kind of locking release screw bolt relates to the locking release screw bolt technical field of common mechanical part class that the taper pin friction lock is set in the body of bolt.
Background technique
Locking problem, the especially vibration component of link caused special concern as the screw retention problem of using on the railway.
Disclosed in first to file 02238327.1 " tightening the locking release screw bolt of friction type " is grooving on screw rod.Practical application screw rod position frangibility.
Disclosed in first to file 02209486.5 " supporting the locking release screw bolt of friction type " is to concentrate the position punching at stress.Consequently the little pin in hole does not return, and is easy to break yet.
Disclosed in first to file 200420064435.4 " the locking release screw bolt of extrusion friction type " is to be provided with the extruding type pin, but does not have spring action, and pin does not return during release, has injured the workpiece screw thread on the contrary.
Summary of the invention
At the deficiency of above-mentioned background technology, the purpose of this utility model provides a kind of not frangibility, establishes the locking release screw bolt of taper pin friction lock compact form in the flexible movements.Main technical schemes:
Outside thread (2), internal thread (12), slide opening (13), pin-and-hole (10), pilot hole (14) are set on external screw rod (1), connect outer six side's bolt heads (3); Screw thread (15), top (16) are set, six side's bolt heads (7) in connecting again on inner screw (4); Connect taper pin (5) and spring (9) in addition in the pin-and-hole (10) on the screw rod (1), with top (16) engagement on the inner screw (4).
Pin-and-hole (10) is perpendicular to the end that external screw rod (1) radially is opened in outside thread (2), and mutually penetrating with pilot hole (14).
The pin-and-hole of being offered on the outside thread (2) (10) is 1-8.Connect a taper pin (5) and spring (9) in each pin-and-hole (10).Described taper pin (5) is cylinder outward, is cone to the inner.Top (16) of the internal cones of taper pin (5) and inner screw (4) are to mesh with angle.
During assembling, loose ring (8) is prevented in connection in locking hole (11), cover (6) is blocked up in connection in pilot hole (14) again.
When connecting workpiece, at first screw external screw rod (1), screw inner screw (4) by certain dynamics then,,, reach locking purpose with the workpiece friction lock because the effect of top (16) expands outwardly taper pin (5).During release, screw out inner screw (4), awl lock (5) is under the effect of spring (9), and automatic drawing back reaches the release purpose.The utlity model has not frangibility, flexible movements, anti-loosing effect reliable performance, advantage of wide range of application.
