Abstract

The invention discloses a novel lock pin device. The novel lock pin device comprises a lock pin base, a lock pin, a rotary shaft, a lock pin handle and a positioning pin. The lock pin is axially divided into a driving section, a shaft shoulder section and a lock pin section, wherein a groove is formed in the driving section. The two ends of a compression spring abut against the wall faces of a shaft shoulder and the lock pin base. A cambered-surface protrusion is arranged at the end portion of the rotary shaft, and the protrusion is arranged in the groove of the driving section of the lock pin. When the rotary shaft rotates, the protrusion can push the two side faces of the groove to drive the lock pin to move axially. The lock pin handle is fixedly connected with the rotary shaft. The positioning pin is arranged in the middle of the lock pin handle, and the two ends of a positioning spring abut against an annular protrusion and a stepped face of a stepped through hole. According to the novel lock pin device, due to the fact that the cambered-face protrusion of the rotary shaft drives the lock pin to stretch or retract axially and the lock pin is sleeved with the compression spring, the axial bumping motion of the lock pin is prevented; due to the fact that the lock pin handle is positioned by the positioning pin, the connection and disconnection of the two parts are achieved, limiting structures are both arranged at the connection position and the disconnection position, operation is flexible, no clamping phenomenon exists, and the working of the novel lock pin device is reliable.

Embodiment

Below in conjunction with specific embodiment, the present invention is described:

With reference to accompanying drawing 1, to accompanying drawing 4, a kind of novel lock pin assembly of the present invention comprises locking pin seat 1, stop pin 3, rotating shaft 4, lock pin handle 8 and locating stud 10.

Locking pin seat is useful on the step through-hole that holds stop pin, and latch cover 5 is fixed in locking pin seat by screw pin 11.Stop pin 3 is arranged in the step through-hole of locking pin seat through latch cover 5.With reference to accompanying drawing 6, stop pin is divided into driving section, shaft shoulder section and lock pin section vertically, wherein drives in section and has groove, and shaft shoulder section is inner in locking pin seat, in shaft shoulder section, cover has Compress Spring 2, and Compress Spring 2 two ends are against on the step surface of the shaft shoulder and locking pin seat step hole.

With reference to accompanying drawing 5, there is square shaft part end, rotating shaft one end, and there is cambered surface projection rotating shaft the other end end.Rotating shaft is also arranged in locking pin seat, and shaft axis is vertical with stop pin axis, and cambered surface projection is in stop pin drives the groove of section, and when rotating shaft is rotated, projection can promote groove bi-side, and drives stop pin axial motion.

Lock pin handle end has square hole, and square hole coordinates with the square shaft part of rotating shaft, and compresses with round nut 6, and assurance lock pin handle 8 and rotating shaft 4 connect firmly and be integral, and rotating shaft 4 can be rotated with lock pin handle 8.Lock pin handle middle part has step through-hole, and locating stud is through step through-hole, and there is annular protrusion at locating stud middle part, and on locating stud, cover has retaining spring, and retaining spring two ends are against on the step surface of annular protrusion and step through-hole.In locking pin seat, have two positioning pin holes, corresponding stop pin is regained and is stretched out the alignment pin position under state respectively, after stop pin 3 is regained or is stretched out and put in place, unclamp locating stud 10, retaining spring 9 extends, and locating stud 10 is sprung in the positioning pin hole in locking pin seat 1, prevents that lock pin handle 8 is rotated further, guarantee that stop pin 3 can left and right play, it is being regained or the state that stretches out is reliably located.

This device in use, by the unthreaded hole in locking pin seat 1, be screwed on a certain component, on another component that need to connect or throw off, at stop pin 3 corresponding positions, be processed with lockpin hole, when two component connect, positioning pin hole locking pin seat 1 is extracted locating stud 10, clockwise rotate lock pin handle 8, stop pin 3 stretches out, stretch into another component pin-and-hole of locking, realize the connection of two component, under this state, lock pin handle 8 is located by locating stud 10, can guarantee the reliable connection between two component.In the time of need to freeing, from positioning pin hole, extract locating stud 10, rotate counterclockwise lock pin handle 8, stop pin 8 is regained, and two connect component throws off, due under this state, lock pin spring 2 is substantially in pressing and state, so stop pin can be to not stretching out direction play, can guarantee that two component reliably throw off.
