Abstract
A hidden type lock head cover device is composed of a cover plate, a cover seat, a reset spring and a fastening piece. A cylindrical part on the cover plate is in clearance fit with a round hole in the cover seat, the cover plate can rotate relative to the cover seat and move in the direction of a rotating shaft, and the reset spring is mounted between the cover plate and the cover seat, so that the cover plate has reset force; the fastening piece presses the reset spring and limits moving stroke of the cover plate in the direction of the shaft. When the cover plate is pushed to rotate, the cover plate moves outwards or inwards in the axial direction, and a lock head key hole is exposed or hidden.
Description
Technical field
The utility model relates to a kind of door lock lid arrangement, particularly a kind of door lock lid arrangement of key-hole hiding.
Background technology
Existing door lock, its keyhole adopts and exposes or slip lid, the mode of renovating.Exposed keyhole, is easier to be subject to the mechanical performance of the ambient influnence tapered ends such as dust; Slip lid and flip-shell tapered end cover structure need to take larger installing space and disguise lower.
Utility model content
The purpose of this utility model is to provide a kind of good concealment, anti-drilling, dustproof, waterproof, and does not take the head covering device of larger space.
For achieving the above object, the utility model provides a kind of built-in lock cranial device, by cover plate, cage, back-moving spring, securing member, formed, and the cylinder on cover plate and cage circular hole matched in clearance, back-moving spring is installed between cover plate and cage.
In some embodiments, cage is provided with ring cam set.
In some embodiments, cover plate adopts salient point to act on the ring cam set of cage.
The beneficial effects of the utility model are that the salient point on cover plate can slide into peak from minimum point along the cam face of cage when hand is stirred cover plate rotation, and cover plate outwards moves along axis of rotation direction, and keyhole of lock exposes.When hand is stirred cover plate rotation again, the salient point on cover plate slides into minimum point along the cam face of cage from peak, and cover plate moves inward along axis of rotation direction, and keyhole of lock is closed.
Accompanying drawing explanation
Fig. 1 is the built-in lock cranial device exploded pictorial structure composition diagram of a kind of embodiment of the utility model.
Fig. 2 is the built-in lock cranial device longitudinal profile schematic configuration diagram of a kind of embodiment of the utility model.
Fig. 3 is the structural representation part drawing of cage in the built-in lock cranial device of a kind of embodiment of the utility model.
Fig. 4 is the structural representation part drawing of the built-in lock cranial device cover plate of a kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 1, built-in lock cranial device, consists of cover plate 1, cage 2, back-moving spring 3, securing member 4.
As shown in Figure 2, built-in lock cranial device, circular hole 22 matched in clearance on cylinder on cover plate 1 11 and cage 2, back-moving spring 3 is installed between cover plate 1 and cage 2, and securing member 4 serves as the effect of pushing down back-moving spring 3 and limiting the stroke that cover plate 1 moves along axle.
As shown in Figure 3, built-in lock cranial device, cage 2 is provided with two circle end face ring cam sets.
As shown in Figure 4, built-in lock cranial device, cover plate 1 is designed with two salient points.
As shown in Figure 2, Figure 3 and Figure 4, when hand is stirred cover plate 1 rotation, the salient point 12 on cover plate 1 can slide into peak from minimum point along the ring cam set 21 of cage 2, and cover plate 1 outwards moves along axis of rotation direction, and tapered end cover is opened, and keyhole exposes; After having turned the key in the lock, then hand is while stirring cover plate 1 rotation, and the salient point 12 on cover plate 1 slides into minimum point along the ring cam set 21 of cage 2 from peak again, under the effect of back-moving spring 3, cover plate 1 moves inward along axis of rotation direction, and tapered end cover is closed, and keyhole is hidden.
As shown in Figure 3, built-in lock cranial device, cage 2 profiles are circular, after installing with electronic lock, mechanical lock panel or lock body, can it rotatablely move relatively, realize the anti-drilling requirement of theftproof lock.
