Description
The utility model relates to a kind of lock core key hole protector of safe-guard door lock.
Existing anti-theft door lock cylinder keyhole is all exposed to be provided with, not latent keeping away property, and after other people fill in keyhole with foreign matter, just be difficult to open security door.
The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of keyhole protective device.
Basic ideas of the present utility model are: establish an over cap on keyhole, this over cap is locked by a locking mechanism, and can be by the same key operated over cap of unblanking.
A kind of specific implementation of the present utility model is: it is characterized in that described safe-guard door lock is the cross lock; between the faceplate part of lock core periphery and panel integral body, be pressed with groove; two axis holes on the opposite side of groove periphery, have been drawn; rotating shaft is housed in the axis hole; torsion spring is housed in rotating shaft; over cap also is loaded in the rotating shaft and with groove and matches; described opening mechanism comprises: drawn a hole on the side of over cap; have through hole at the groove periphery with corresponding position, hole; be fixed with guide strip and guiding trestle in the corresponding position of back side of panel; there is a locking bar one end to pass guide strip; the other end passes guiding trestle, is provided with boss at the locking bar middle part, and spring is housed on locking bar; and spring is controlled by between boss and the guiding trestle, and locking bar one end passes behind the through hole with hole on the over cap side and cooperates.On or panel a little more than lug boss position corresponding, have jack with boss.According to different keys, can be designed to different jacks.
Described guiding trestle 9 and guide strip 6 also can be designed to integral body.
Further scheme is: described boss can be the ring that is positioned at the locking bar middle part, and the projection of jack is positioned at ring.
Further scheme is again: described rotating shaft is loaded on groove top, and the axis normal of locking bar is in the axis of rotating shaft.
The utility model has the advantages that: lock core has latent keeping away property, and other people can't fill in keyhole with foreign matter when no key or corresponding tool, has strengthened the safety of security door.
Fig. 1 is the assembling drawing of embodiment of the present utility model.
Fig. 2 is the Theft-proof Door Panel schematic diagram.
Fig. 3 is that the B of Fig. 1 is to view.
Below in conjunction with accompanying drawing the utility model is done detailed description.
As Fig. 1; Fig. 2; Fig. 3; a kind of Key for anti-theft door lock hole protector; relate to Theft-proof Door Panel 1; be loaded on the security door cross lock pin 5 on the panel 1; between panel 1 part of lock core 5 peripheries and panel integral body, be pressed with groove 11; two axis holes on the opposite side of groove 11 peripheries, have been drawn; rotating shaft 2 is housed in the axis hole; torsion spring 3 is housed in rotating shaft 2; over cap 4 also is loaded in the rotating shaft and with groove 11 and matches; described opening mechanism comprises: drawn a hole 13 on the side of over cap 4; have through hole 12 at groove 11 peripheries with 13 corresponding positions, hole; be fixed with guide strip 6 and guiding trestle 9 in the corresponding position at panel 1 back side, have a locking bar 7 one ends to pass guide strip 6, the other end passes guiding trestle 9; be provided with ring 14 at locking bar 7 middle parts; spring 8 is housed, and spring 8 is controlled by between ring 14 and the guiding trestle 9 on locking bar 7, locking bar 7 one ends pass through hole 14 afterwards and the holes 13 on over cap 4 sides cooperate.With the ring 14 relevant positions panel 1 on have jack 10.
In the present embodiment, and the orthography of jack 10 be positioned at the ring 10 bottoms.Described rotating shaft 2 levels are loaded on groove 11 tops, and the axis normal of locking bar 7 is in the axis of rotating shaft 2.
Its using method is: vertically insert in the jack 10 on the Theft-proof Door Panel 1 with the key of opening the cross lock; because of the front end of key is a cone; cone is withstood ring 14 surface promotion locking bars 7 and is moved downward under the control of guide strip 6 and guiding trestle 9; spring 8 is compressed; the upper end of this hour locking lever 7 withdraws from from the hole 13 of over cap 4 lower ends; and over cap 42 is upspring under the effect of torsion spring 3 around the shaft, at this moment takes off key, and locking bar 7 is got back to original position under the effect of stage clip 8.
After over cap 4 was upspring, lock core keyhole exposed, and at this moment was available key operated or close door lock.
After opening or closing door lock, as long as over cap 4 is down pressed, the conical surface of locking bar 7 ends promotes locking bar to lower compression, and hole 13 on over cap 4 and locking bar upper end are to timing, and locking bar 7 pins over cap 4 again under the effect of pressing bullet 8.
