Abstract
The utility model relates to a lockset component, particularly an anti-drilling sleeve for a core-insert lock head. The utility model solves the defects of the existing anti-drilling sleeve for the lock head that only a section on the lock head body, which approaches to a lock hole, is covered, and a connection bridge of a lock head body is not protected, and the lock head is easily smashed and broken. The utility model has the technical proposal that the anti-drilling sleeve for the core-insert lock head is sheathed and connected to the lock head body. The utility model is characterized in that the anti-drilling sleeve is in an L shape and is sheathed with the section on the lock head body and the connection bridge of the lock head body, and the section on the lock head body is close to the lock hole. The corresponding place of the anti-drilling sleeve and an installation connection hole of the connection bridge of the lock head body is provided with a hole, and the anti-drilling sleeve and the lock head body are connected and fixed on a lock body by a bolt. The utility model is mainly used for the drilling prevention and the smashing prevention of the core-insert lock head and has theft protection to a lockset.
Description
One, technical field
The utility model relates to a kind of parts of lockset, and particularly a kind of inserting-core lock is prevented drill bushing.
Two, background technology
Existing core-inset type mechanical anti-theft lock, in order to prevent destruction to tapered end, installed anti-drilling sheet additional in the lockhole position, install anti-drill bushing additional in the tapered end position, shift fork is equipped with at middle part at tapered end, need on the corresponding tapered end connecting bridge of installation shift fork opening, have the installation connecting hole for what assemble, make that the intensity of tapered end connecting bridge is lower.In use, find that disconnected if the burglar is pounded tapered end, tapered end disconnects respectively in indoor and outdoor, makes that the burglar can be easy to lock is opened because the anti-drill bushing of tapered end only entangles the part of tapered end near lockhole.
Three, summary of the invention
The utility model technical issues that need to address are: increase the intensity of tapered end connecting bridge, when the tapered end fracture took place, outdoor tapered end part can not separated with lock.The technical solution of the utility model is: inserting-core lock is prevented drill bushing, is socketed on the tapered end, it is characterized in that: anti-drill bushing is
Type entangles part and the tapered end connecting bridge of tapered end near lockhole, and anti-drill bushing and tapered end connecting bridge are installed connecting hole corresponding position perforate, utilize bolt will prevent that drill bushing and tapered end are fastened on the lock body.The beneficial effects of the utility model are: owing to install anti-drill bushing additional at tapered end connecting bridge position, increased the intensity of tapered end connecting bridge, and when the tapered end fracture takes place, because anti-drill bushing is bolted on the lock body, outdoor tapered end part can not separated with lock, has strengthened the theftproof of lock greatly.
Four, description of drawings Fig. 1 is that the utility model structural representation front view Fig. 2 is among the utility model structural representation left view figure: 1-tapered end, 2-are prevented drill bushing, the 3-anti-drilling sheet, and the 4-shift fork, 5-tapered end connecting bridge, 6-installs connecting hole.
Five, the specific embodiment
With reference to Fig. 1,2, tapered end is made of tapered end, shift fork, installs anti-drilling sheet additional in the lockhole position, installs anti-drill bushing additional in the tapered end position, and anti-drill bushing is
Type entangles part and the tapered end connecting bridge of tapered end near lockhole, and anti-drill bushing and tapered end connecting bridge are installed connecting hole corresponding position perforate, utilize bolt will prevent that drill bushing and tapered end are fastened on the lock body.
