Description
Technical field
The utility model relates to lockset dust cap, and more particularly, it relates to a kind of lock dust cap.
Background technology
U-shape lock and steel cable lock are locksets common at present, are usually used on the vehicles such as bicycle, electric motor car with two wheels, motorcycle as lock.For U-shape lock, generally include U-shape lock bar and lock body, described lock body comprises lock head component, stop and lock body shell, and lock head component and stop are arranged in lock body shell, and U-shape lock boom end is mortise lock end, described lock body shell is provided with mortise lock hole, described mortise lock end can insert with mortise lock hole and extract and coordinate, and one end of U-shape lock is provided with key hole, inserts key hole from key, control stop position by lock head component, locking or unblock are carried out to the mortise lock end inserted in mortise lock hole.General all in outdoor application due to U-shape lock, in environment for use, usual dust is more, after use after a while, can enter dust unavoidably in key hole, can affect the normal use of U-shape lock, and therefore preferably join a dust cap, steel cable lock too.Existing dust cap generally includes the barrel and a deck portion that match with lock body, one lateral edges of deck portion is connected with barrel by brace or connecting band, and deck portion is connected by the structure of buckle the object reaching closing lid usually with barrel.The dust cap of this spline structure is after a period of time uses, and have wearing and tearing, the engaging effect of the structure of buckle can decline, and covering of cover plate is unreliable, loses the function of dust cap.
Summary of the invention
The purpose of this utility model is the deficiency existed for overcoming prior art, and provides that a kind of structure is reliable, the lock dust cap of long service life.
For achieving the above object, the utility model provides following technical scheme: a kind of lock dust cap, it is characterized in that: comprise the socket part of one end with the cylindrical shape of bottom, spiral cover and flashboard, described spiral cover rotatably cover cap is provided with in socket part on the end of bottom, the end face of described spiral cover and the bottom centre of socket part are provided with the through hole for inserting key, one end of described flashboard is arranged between the outer face, bottom of socket part and the inner face of spiral cover by a pivot swingably, described flashboard and spiral cover are connected in circumference, described flashboard has the first swing position and the second swing position, under first swing position, described flashboard is in through hole side, under second swing position, described flashboard is in lead to the hole site and is closed by through hole.
The utility model by being provided with flashboard between the outer face, bottom and the inner face of spiral cover of socket part, flashboard and spiral cover are connected, only need rotate spiral cover flashboard and can complete closing or opening the through hole inserting key, very easy to use, and do not have the wearing and tearing of similar existing dust cap, reliable operation, longer service life.
Below in conjunction with specific embodiments and the drawings, the utility model is described further.
