Abstract
The utility model relates to dustproof device of a tapered end, comprising a tapered end body whose end portion is connected with an end cover which is provided with a key plug jack which is opposite to a lock core hole. A dustproof piece is movably arranged in a sandwich layer between the tapered end body and the end cover, and can be also provided with opening holes which are matched with the lock core hole and the key plug jack, and the dustproof piece is movably positioned on the tapered end body or the end cover by pins. The pushing knob of the dustproof plate is protruded outside the presetting sliding slot of the end cover. The dustproof device of the tapered end overcomes the defect that the dustproof cover of the existing dustproof structure of the tapered end is easily drawn out and shed. With the design, the open and the close of the dustproof piece can be accomplished by pushing the pushing knob right and left, the dustproof device of the tapered end convenient use and operation, simple and compact structure, flexible opening and high reliability.
Description
Affiliated technical field
The utility model relates to a kind of tapered end dust guard.
Background technology
Traditional tapered end dustproof construction all is pusher, need shift dust cap onto the outside of tapered end when opening, and not only influences the overall appearance of lock body, and dust cap also is easy to be drawn out come off, thereby loses dust reduction capability.
Summary of the invention
For the dust cap that overcomes tapered end dustproof construction in the prior art is easy to be drawn out the problem that comes off, the utility model provides a kind of tapered end dustproof construction, this tapered end dustproof construction simple and compact for structure, easy to operate, open flexibly, good reliability.
The technical scheme that its technical problem that solves the utility model adopts is: comprise tapered end, end at tapered end connects end cap, offer the key hole relative on the end cap with lock core hole, activity is provided with dustproof sheet in the interlayer between tapered end and end cap, and the push button of dustproof sheet is given prominence to outside the chute that end cap presets.
Dustproof sheet passes through the pin activity orientation on tapered end or end cap.
On dustproof sheet, also be provided with the perforate that is complementary with lock core hole, key hole.
The utility model is by above-mentioned specific design, promotes the switching that push button can be realized dustproof sheet about only needing, and uses that operation is very easy, have simple and compact for structure, open flexibly, the advantage of good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of opening;
Fig. 3 is the schematic diagram of closed condition.
As shown in the figure, the utility model comprises tapered end 1, end at tapered end 1 connects end cap 2, offer the key hole 4 relative on the end cap 2 with lock core hole 3, activity is provided with dustproof sheet 6 in the interlayer between tapered end 1 and end cap 2, also can be provided with the perforate 8 that is complementary with lock core hole 3, key hole 4 on dustproof sheet 6, on tapered end 1 or end cap 2, give prominence to outside the chute 7 that end cap 2 presets by the push button 5 of dustproof sheet 6 by pin 9 activity orientation for dustproof sheet 4.When using operation, promote push button 5 counterclockwise, can open dustproof sheet 5 and expose lock core hole 3; Promote push button 5 clockwise, dustproof sheet 6 covers lock core hole 3.
