Description

A kind of lock in place device

Technical field

The application relates to positioning device, is specially a kind of lock in place device.

Background technique

Positioning device for rotatable parts is often to relate in some equipment, for example, in the drawer moving device, need to the advanced positions of drawer be positioned, and the mechanism that drives drawer to advance, as gear train, its pivotal position is inevitable associated with the advanced positions of drawer, therefore for the rotatable parts of this gear train type, positions and needs.Traditional lock in place device just, under the effect of Returnning spring, when the lock in place hole turns to the position relative with the lock in place pin, during pin just is inserted into hole under the effect of reposition force, thereby is realized lock in place.But when in use, often sometimes do not need to carry out this location, for example, when the test of equipment or other operating modes.At this moment need to forbid some lock in place pins.And need in suitable, can enable these locating studs again.And at this forbidding and the locating stud of being changed between enabling in existing technology, do not arranged.

Summary of the invention

The present invention is in order to overcome defect of the prior art, and a kind of lock in place device is provided, and it can be changed at forbidding and between enabling as required, and has improved reliability.

Scheme is: a kind of lock in place device, comprise: the first fixed plate, the second fixed plate, the lock in place pin, Returnning spring, the first fixed plate and the second fixed plate be arranged in parallel, and there is the through hole passed for described lock in place pin in the first fixed plate, be provided with sleeve on the second fixed plate, there is sleeve hole corresponding with the through hole on described the first fixed plate and that pass for described lock in place pin in sleeve, described the first fixed plate and the second fixed plate all are fixedly installed on support, the lock in place pin has the keyed end that engaged for the positioning hole with on lock object and manually pulls end for what manually pull described lock in place pin, be arranged with flange nut on described lock in place pin, described lock in place pin is arranged with described Returnning spring between flange nut and the first fixed plate, under the compression force of described Returnning spring, described stop pin can be pressed towards lock object, at described the second fixed plate, be provided with the locking pin-and-hole perpendicular to longitudinal direction in the lock in place pin, lock pin and lower lock pin are set in the locking pin-and-hole, between upper lock pin and lower lock pin, arrange two described lock pin top Compress Springs laterally, there is respectively the friction lines on the outside end face of upper lock pin and lower lock pin, there is away from a side of lock object the friction zone that the friction lines for the outside end face with upper lock pin and lower lock pin engages on the inner peripheral surface of sleeve, a side near lock object on the inner peripheral surface of sleeve has the sliding area that can be slidably matched with the outside end face of upper lock pin and lower lock pin, when described lock in place pin, under the effect of manual motive force, vertical shift occurs, when described Compress Spring pushes up to described friction zone by the friction lines of the outside end face of described upper lock pin and lower lock pin, frictional force between described friction lines and friction zone can be resisted the reposition force of action of reset spring on the lock in place pin, thereby make the lock in place pin realize the lengthwise position locking, when when manually pulling on end the thrust applied towards described lock object, can overcome described frictional force and the lock pin of lock in place pin is released to friction zone and pushed sliding area to.

Pass through said system, there is the friction zone and the sliding area that match with the outside end face of upper lock pin and lower lock pin on the inner peripheral surface of sleeve, by pulling the end that pulls of lock in place pin, the lock in place pin is changed between can realizing as required being locked at the lengthwise position locking with to lock object, easy to operate, reliability is high.
