The position to match with cover is provided in the side of padlock body bottom and is provided with circular blind hole, in blind hole
Bottom end is additionally provided with the annular groove of a circle, and the aperture of annular groove is more than the aperture of blind hole, the width of annular groove and limiting
The arc tips of pin are suitable, offer a round hole in that side of annular groove in the middle part of lock body, set in the side of round hole
The transition face of arc is equipped with, transition face is transitioned into annular groove, the aperture of the round hole and the size phase of spacer pin arc tips
Matching, spacer pin can be extend into the arc groove, and the blind hole in rotation axis is consistent with the orientation of the round hole on lock body.
The cover of this structure when in use, the rotation axis in cover is pressed into the blind hole of lock body side, until limiting
The arc tips of pin are snapped onto in the semicircle orifice of annular groove so that spacer pin is positioned in this round hole, so as to fulfill lid
Assembling of the body on lock body, so as to fulfill the protection to lock core hole, when needing to open this padlock, it is only necessary to rotating cover, limit
After position pin is squeezed by round hole, squeezes spring, slide into annular groove along arc transiting surface and moved along annular groove
It is dynamic, cover is made to be rotated along annular groove, without being disengaged out of lock body.After the completion of operation, cover is rotated backward, works as limiting
When pin is aligned with semicircle orifice, spacer pin is sprung into semicircle orifice under the action of the spring, so as to limit the further rotation of cover.
In summary, present invention advantage following compared with prior art：
A kind of lockset hole protective device of the present invention, can be installed in lock body without screw fixation, be revolved around lock core
Turn, realize the protection to lock core hole, and, on the direction for covering lock core hole, which has position-limit mechanism, ensures the guarantor
Protection unit is consistent with lockset direction.The invention simple structure, installation application is convenient, and protection well is played to lock core hole and is made
With avoiding the influence climbed into lockset of small worm, spider etc., extend the service life of lockset, ensured the just normally opened of lockset
It opens, ensures the normal operating of power system device.

Specific embodiment
The present invention is described in more detail with reference to embodiment.
Embodiment 1
A kind of lockset hole protective device includes padlock, and the padlock includes lock body, and structural feature is：Also
Include cover, the cover includes the panel of plate, and the specification of panel is suitable with the specification of padlock bottom, in panel
One end is provided with columned rotation axis, on the rotating shaft the blind hole that radially extends of the side setting in portion along rotation axis, also
Including spacer pin and spring, one end of spring is connected to the blind-hole bottom of rotation axis, and the other end of spring is connected with spacer pin,
Spacer pin protrudes from the peripheral surface of rotation axis when being in the normal state, and the end face of spacer pin is arc-shaped transition；
The position that a side of padlock body and cover match is provided with circular blind hole, is also set in the bottom end of blind hole
The annular groove of a circle is equipped with, the aperture of annular groove is more than the aperture of blind hole, the width of annular groove and the arc of spacer pin
