Description
Technical Field
The utility model belongs to the technical field of the key cover, concretely relates to emergent key cover of anti-drop.
Background
Present lock is fingerprint lock generally, but still can remain mechanical key hole on the fingerprint lock to in case the fingerprint is invalid, can open the gate with traditional key, but because fingerprint lock uses password function or fingerprint function under the general condition, use mechanical key seldom, the key hole that leaves makes dirty very easily like this, and general key cover drops the loss easily on the key hole, for this, the utility model provides an anti-drop emergency key cover.
SUMMERY OF THE UTILITY MODEL
For solving the defects of the prior art, the utility model aims to provide an anti-drop emergency key cover solves the technical problems that the fingerprint lock does not have the key cover and the key cover is easy to drop in the prior art
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides an anti-drop emergency key cover, includes the detachable key cover main part of installing on the lock casing, the key cover main part includes the top cap, latch mechanism is installed in the bottom left side of top cap, coupling mechanism is installed on the bottom right side of top cap, latch mechanism includes the joint board that two symmetries set up, coupling mechanism includes the connecting plate that two symmetries set up, two be provided with the spring part between the connecting plate, two the lower extreme of connecting plate is fixed with the spacing piece.
Preferably, a storage groove is formed in the key hole of the lock shell, and the top cover is matched with the storage groove in shape and size.
Preferably, the clamping plate is of an arc structure, and the clamping plate is matched with the keyhole in shape.
Preferably, the outer wall of the clamping plate is provided with an arc-shaped clamping protrusion.
Preferably, one side of each of the two connecting plates, which is close to each other, is provided with a mounting groove, and two ends of the spring element are respectively fixed in each mounting groove.
Preferably, a vertical cross-section of the limiting blocks is of a right trapezoid structure, the accommodating grooves are provided with connecting holes, the limiting blocks enter the connecting holes simultaneously when being close to each other, and the two limiting blocks are clamped into the connecting holes when the spring piece is in an initial state.
The utility model discloses the beneficial effect who reaches:
when installation key cover main part, hold between the fingers two connecting plates with the hand, insert the connecting hole with two stoppers when making two stoppers be close to, then loosen the hand, under the recovery of spring part, two stoppers are blocked in the connecting hole, pull out key cover main part this moment and also can not pull out the stopper from the connecting hole, just so can realize anti-drop's function, the utility model discloses rational in infrastructure, design benefit has anti-drop's function, can play the guard action to the key hole, avoids the dust to get into in the key hole, is fit for using widely.
