Abstract

The utility model discloses a lock assembly equipped with a dust-proof cover for an anti-theft generator, which comprises a complete lock body structure of a current lockset, and provides a dust-proof cover connected by a screw from convex edge in the position in respect to a lock cylinder on the lock body, rotating along the screw to open and close, and the screw is provided to connect dust-proof cover through the end cap of the lock body, and provided with a tower-shaped spring between top boss of screw and inside boss of end cap of the lock body which is held down toward dust-proof cover by screw, dust-proof cover is pulled toward the end cap by elastic force of the spring to make the dust-proof cover tightly cover the end cap, and, meanwhile, avoid rotation of dust-proof cover for elastic force. The utility model has advantages of simple and reasonable structure, and convenient switch, avoiding erosion of dust and rain of the lock cylinder, extending using time of lock cylinder and lock set composition, and improving working environment of lockset.

Description

The band dust cap lockset combination of antitheft motor

Technical field

The utility model belongs to the lockset technology, is specifically related to a kind of lockset combination with antitheft motor of dust cap.

Background technology

The lockset combination of present antitheft motor does not design dustproof construction, and its lock core exposes, and is contained on motor, the car load, can enter lock core because of dust, rainwater etc. when the user uses, and influences the reliability of lock core.

Simultaneously, prior art has the dust guard design that relates to bicycle, motorcycle lockset, as cover-lifting type, slide rail type and piston type dust cap, but there is certain deficiency separately in they, in using, easily come off, easily break, easily with peripheral structure overslaugh mutually, use inconvenience etc., therefore be difficult to adapt to well the needs in market always.

Summary of the invention

Of the present utility model at existing lockset dustproof construction above shortcomings, provide a kind of band dust cap lockset combination, to reach rational in infrastructure at antitheft motor, reliable operation, easy to use, improve the application life that lock core and lockset make up, improve the purpose of working environment.

The technical solution of the utility model is as follows:

A kind of band dust cap lockset combination of antitheft motor comprises the complete lock body structure of existing lockset, and corresponding to the lock core position one dust cap is set on lock body, enters lock core to prevent dust, rainwater etc.Under normal condition, dust cap covers the lock core part, when needing the switch lock core, opens dust cap earlier and gets final product.

For convenience of the switch of dust cap, this dust cap is to be connected with lock body by screw by side flanges, and is an axle rotation realization switch with the screw.

Further, for under the situation that guarantees smooth and easy switch, make dust cap tighter lock core hole that thickly covers of energy after closing, play reliable dustproof and rainproof water effect, the utility model design dust cap is connected with lock body by tapping screw, tapping screw is worn in public from the end cap of lock body and is connected dust cap, and the turriform spring is installed between the inner convex platform of the head boss of tapping screw and lock body end cap, by tapping screw it is compressed to the dust cap direction, so just can by tapping screw dust cap be pulled to the end cap direction, dust cap is tightly covered on the end cap of lock body by the elastic force of spring; Simultaneously, because the existence of elastic force, rotation that also can the convenient dust-proofing lid.

As seen, the dust cap that the utility model is simple and reasonable by increasing on lock body, switch is convenient and reliable can effectively prevent dust and rain erosion lock core, has improved the application life of lock core and lockset combination, has improved the working environment that lockset has.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the end cap of lock body among Fig. 1 and the plan view of dust cap coupling part;

Fig. 3 is the D-D profile of Fig. 2.

The specific embodiment

The utility model is to realize on the basis of the complete internal construction of the lockset combination that keeps existing antitheft motor, referring to Fig. 1, and the 5th, the lock body of the lockset combination of antitheft motor connects a dust cap 3 on the end cap 4 outside the lock core of lock body 5.Referring to Fig. 2 and Fig. 3, dust cap 3 and the connected mode of end cap 4 are that the flange by dust cap 3 sides is connected with end cap 4 by tapping screw 1, mode is that tapping screw 1 passes from inside to outside from end cap 4 and connects dust cap 3 preferably, and turriform spring 2 is installed between the inner convex platform B of the head boss A of tapping screw 1 and lock body end cap, by tapping screw 1 turriform spring 2 is suitably compressed to dust cap 3 directions during assembling, guaranteeing smooth and easy switch, and tight dustproof and rainproof.

Claims

1, the band dust cap lockset of antitheft motor combination includes lock body, it is characterized in that: be provided with dust cap corresponding to the lock core position on lock body.

2, band dust cap lockset according to claim 1 combination is characterized in that: described dust cap is that the flange by the side is connected with lock body by screw, and is a rotation with the screw.

3, band dust cap lockset combination according to claim 1, it is characterized in that: described dust cap is that the flange by the side is connected with lock body by tapping screw, tapping screw passes the connection dust cap from the end cap of lock body, and the turriform spring is installed between the inner convex platform of the head boss of tapping screw and lock body end cap, by tapping screw it is compressed to the dust cap direction.
