Inner core assembly of lock

Abstract

The invention relates to an inner core assembly of a lock. The inner core assembly comprises a return spring with two positioning ends, a handle head, a shifting piece, a front cover and a rear cover,wherein a mounting cavity is formed between the rear cover and the front cover, the handle head comprises a rotating part and a handle connecting part, the rotating part is rotationally arranged on the front cover and the rear cover in a penetrating mode, and the shifting piece and the rotating part are synchronously rotated; a first limiting step and a second limiting step are arranged on the rotating part, the first limiting step abuts against the front cover, and the second limiting step abuts against the rear cover; and two protruding blocks are oppositely arranged on the side, facing therear cover, of the front cover, and shifting blocks are arranged on the positions, corresponding to the two positioning ends of the return spring, of the shifting piece respectively. By adopting thetechnical scheme, the inner core assembly of the lock does not need to be provided with a clamping spring, a clamping spring groove and the like, the installation is convenient, and the assembling efficiency is high; and moreover, the shifting piece, the return spring and the like can be arranged in the mounting cavity so as to avoid the influence of external environmental factors, and the stability is good.

Description

technical field [0001] The invention relates to the field of door locks, in particular to an inner core assembly of a lock. Background technique [0002] The Chinese invention patent with the patent number of 201510216835.5 discloses an inner core assembly of a lock, which includes a return spring with two positioning ends, a bottom plate, a penetration hole on the bottom plate, and a fixed connection between the rotating shaft and the bottom plate. The handle, the handle is installed on the penetration hole, the rotating shaft and the bottom plate are respectively located on both sides of the bottom plate, and the bottom plate is set against the side of the bottom plate, and the bottom plate has an arc-shaped convex edge extending outward; The return spring is sleeved on the rotating shaft and conflicts with the bottom plate, and the two positioning ends on it are respectively located outside the two ends of the arc-shaped convex edge, and the rotating shaft is sleeved in a...
