Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and provide one to be arranged on lockset, simple structure, easy to operate, effectively can avoid entering of the small worm such as spider, cockroach, reduce the lockset hole protective device of the impact of dual lock.
A kind of lockset hole protective device, include padlock, described padlock includes lock body, its structural feature is: also include lid, described lid includes the panel of tabular, specification bottom the specification of panel and padlock is suitable, an end of panel is provided with columned turning cylinder, the side in portion arranges the blind hole that the radial direction along turning cylinder extends on the rotating shaft, also include spacer pin and spring, one end of spring is connected to the blind-hole bottom of turning cylinder, the other end of spring is connected with spacer pin, spacer pin protrudes from the outer peripheral face of turning cylinder when being in the normal state, the end face of spacer pin is arc-shaped transition,
Side bottom padlock body is provided with the position matched with lid and is provided with circular blind hole, the annular groove of a circle is also provided with in the bottom of blind hole, the aperture of annular groove is greater than the aperture of blind hole, the width of annular groove is suitable with the arc tips of spacer pin, a circular port is offered in annular groove that side in the middle part of lock body, the transition face of arc is provided with in the side of circular port, transition face is transitioned in annular groove, the aperture of this circular port and the size of spacer pin arc tips match, spacer pin can extend in this deep-slotted chip breaker, blind hole on turning cylinder is consistent with the orientation of the circular port on lock body.
The lid of this structure, in use, by in the blind hole of the turning cylinder press-in lock body side on lid, until the arc tips of spacer pin snaps onto in the middle of the semicircle orifice of annular groove, spacer pin is made to be positioned in this circular port, thus realize the assembling of lid on lock body, thus the protection realized lock core hole, when this padlock opened by needs, only need rotating cover, spacer pin is by the extruding of circular port, after extrusion spring, to slide in annular groove along arc transiting surface and move along annular groove, lid is rotated along annular groove, and can not throw off in lock body.After operation completes, rotate backward lid, when spacer pin aligns with semicircle orifice, spacer pin springs in semicircle orifice under the action of the spring, thus limits the further rotation of lid.
In sum, the present invention's following advantage compared to existing technology:
A kind of lockset hole of the present invention protective device, just can be installed in lock body without the need to screw is fixing, rotate around lock core; realize the protection to lock core hole, and, on the direction covering lock core hole; this protective device has position-limit mechanism, ensures that this protective device is consistent with lockset direction.This invention simple structure, installs application conveniently, plays a very good protection to lock core hole; avoid the impact climbed into lockset of small worm, spider etc.; extend the application life of lockset, ensured the normal unlatching of lockset, ensure the normal operating of power system device.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in more detail.
Embodiment 1
A kind of lockset hole protective device, include padlock, described padlock includes lock body, its structural feature is: also include lid, described lid includes the panel of tabular, specification bottom the specification of panel and padlock is suitable, an end of panel is provided with columned turning cylinder, the side in portion arranges the blind hole that the radial direction along turning cylinder extends on the rotating shaft, also include spacer pin and spring, one end of spring is connected to the blind-hole bottom of turning cylinder, the other end of spring is connected with spacer pin, spacer pin protrudes from the outer peripheral face of turning cylinder when being in the normal state, the end face of spacer pin is arc-shaped transition,
Circular blind hole is provided with in the position that a sidepiece and the lid of padlock body match, the annular groove of a circle is also provided with in the bottom of blind hole, the aperture of annular groove is greater than the aperture of blind hole, the width of annular groove is suitable with the arc tips of spacer pin, a circular port is offered in annular groove that side in the middle part of lock body, the transition face of arc is provided with in the side of circular port, transition face is transitioned in annular groove, the aperture of this circular port and the size of spacer pin arc tips match, spacer pin can extend in this deep-slotted chip breaker, blind hole on turning cylinder is consistent with the orientation of the semicircle orifice on lock body.
As shown in Figure 2,3, be the constructional drawing of lock body 1 of the present invention, comprise circular blind hole 11, blind round hole 11 has an annular groove 12 above, annular groove is provided with a circular port 13, there is an arc transiting surface 14 circular port 13 side, and this arc transiting surface 14 is near lock core hole;
