Background technology
Security door and interior door hand holding lock are the locksets of consumption maximum, it comprises lock core, elastic lock tongue, theft-proof bolt, the dead bolt operating mechanism, lock housing, when laying the key under the door with key from the outside, key inserts lock core body and rotates, lock core body drives the fork of unblanking by inside and outside brace, the fork of unblanking drives theft-proof bolt by the dead bolt operating mechanism and stretches out, key generally can rotate two circles, the key theft-proof bolt that rotates a circle stretches out one grade and locks, the key theft-proof bolt that rotates two circles stretches out second gear and locks, but the rotation knob on the rotational lock core inside, lockset still can be opened, the thief will be taken place like this after climb into theft outside window, can hold the theft article and come out of with a swagger from the doorway, lockset does not have antitheft effect fully.When laying the key under the door with the rotation turning knob from the inside, use key or the higher thief of technology can utilize the mode of technical opening can open lockset equally, lockset is caught up with and is not had preventive effect, and the security of the lives and property can not get ensureing.For this reason, many manufacturers and knowledgeable people have carried out R and D at the problems referred to above, but do not have desirable product to emerge so far.
Summary of the invention
For overcoming existing security door and the existing above-mentioned deficiency of interior door hand holding lock lock core, the purpose of this utility model provides a kind of simple and reasonable, easy for operation, good, inside and outside two-way safe lock cylinder that can insure of theftproof performance.
The utility model solves the problems of the technologies described above the technical scheme that adopts, it comprises lock core body, tapered end, the fork of unblanking, inside and outside brace, connecting bushing, turning knob, described lock core body, the coaxial setting of connecting bushing and turning knob and rotating being successively set on the tapered end, one end of inside and outside brace is arranged on the endoporus of lock core body, the other end is arranged on the slot of connecting bushing, the fork of unblanking is arranged on the inside and outside brace, the endoporus of lock core body is provided with the spacing rib that matches with inside and outside brace, and the dwang of connecting bushing is set on the hollow rotation axis of turning knob.
Be provided with first spring of the inside and outside brace of roof pressure in the slot of described connecting bushing.
The hollow rotation axis of the described turning knob dwang of connecting bushing relatively moves axially, the dwang of connecting bushing is provided with the hoodle hole, correspondence is equipped with retainer spring and hoodle on the hoodle hole, the corresponding second gear detent that matches with hoodle that is provided with on the hollow rotation axis of turning knob.
Be provided with second spring of roof pressure dwang in the hollow rotation axis of described turning knob.
The hollow rotation axis of described turning knob is provided with the insurance external tooth, and tapered end is provided with and insures the insurance internal tooth that external tooth matches.
After adopting said structure, following advantage and effect are arranged compared with the prior art: the one, when locking from the outside with key, the rotation turning knob, turning knob drives connecting bushing, connecting bushing drive inside and outside brace can only rotate a circle less than, just be subjected to stopping of spacing rib, so theft-proof bolt is only to open one grade, can not open theft-proof bolt fully, thereby reach the purpose that outside locking, the inside can not be opened, further improve the safe antitheft performance.The 2nd, when pressing turning knob from the inside, hoodle matches with the detent of the inside, insurance external tooth on the hollow rotation axis inserts in the insurance internal tooth of tapered end, turning knob can not rotate, make connecting bushing, inside and outside brace and unblank also different rotation of fork, so when the inside was insured, the pick-proof performance of lockset had further been improved no matter be all can't open lockset with key or technical opening in the outside.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 key wherein, 2 lock core bodies, 3 tapered ends, 4 spacing ribs, 5 forks of unblanking, 6 inside and outside braces, 7 first springs, 8 connecting bushings, 9 hoodles, 10 retainer springs, 11 detents, 12 hollow rotation axiss, 13 second springs, 14 insurance internal tooths, 15 insurance external tooths, 16 turning knobs, 17 dwangs.
The specific embodiment
Shown in Figure 1, specific embodiments for the two-way safe lock cylinder of the utility model, it comprises lock core body 2, tapered end 3, the fork 5 of unblanking, inside and outside brace 6, connecting bushing 8, turning knob 16, described lock core body 2, connecting bushing 8 and turning knob 16 coaxial settings and by jump ring rotating being successively set on the tapered end 3 respectively, one end of inside and outside brace 6 is arranged on the endoporus of lock core body 2, the other end is arranged on the slot of connecting bushing 8, the fork 5 of unblanking is arranged on the inside and outside brace 6, the endoporus of lock core body 2 is provided with the spacing rib 4 that matches with inside and outside brace 6, the dwang 17 of connecting bushing 8 is set on the hollow rotation axis 12 of turning knob 16, is provided with first spring 7 of the inside and outside brace 6 of roof pressure in the slot of described connecting bushing 8.
The hollow rotation axis 12 of described turning knob 16 dwang 17 of connecting bushing 8 relatively moves axially, dwang 17 is square shaft preferably, hollow rotation axis 12 is square hole preferably, during rotation, inside and outside brace 6, connecting bushing 8 and turning knob 16 rotate synchronously, the dwang 17 of connecting bushing 8 is provided with the hoodle hole, correspondence is equipped with retainer spring 10 and hoodle 9 on the hoodle hole, the corresponding second gear detent 11 that matches with hoodle 9 that is provided with on the hollow rotation axis 12 of turning knob 16, hoodle 9 plays positioning action, second spring, 13, the second springs 13 that are provided with roof pressure dwang 17 in the hollow rotation axis 12 of described turning knob 16 play reset response.
