Description
Technical field
The utility model relates to a kind of tapered end.Also relate to I-shaped key with above-mentioned tapered end coupling.
Background technology
The tapered end of Xiao Shouing generally comprises lock core, lock housing and page or leaf sheet in the market, each level generally just disposes a page or leaf sheet, only need the single lock tooth coupling of key just can open key during release, therefore cause the safety guarantee poor-performing locked, often lock core and lock housing are in stuck state mutually to this in addition tapered end under blocking, therefore the person lives lock core surely to make things convenient for the picking lock, carries out next step illegal release work, therefore further causes the reduction of safety guarantee performance.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of tapered end of safety guarantee better performances simple in structure.Technical problem to be solved in the utility model also comprises the key that a kind of and above-mentioned tapered end coupling is provided.
For this reason, the tapered end that the utility model provides comprises lock core, lock housing and page or leaf sheet, lock housing comprises shell and mesochite, wherein mesochite and lock core can relatively rotate, the page or leaf sheet comprises many group verso sheets and recto sheet, verso sheet and the overlapping setting of recto sheet, the verso sheet comprises left spring block piece and verso sheet main body, the recto sheet comprises right spring block piece and recto sheet main body, be provided with leaf spring between left spring block piece and the right spring block piece, be distributed with slot on verso sheet main body and the recto sheet main body, corresponding slot offers the through hole that vertical bar shaped distributes on the lock core, be provided with in the through hole and slot coupling inner edge bumping post, aligned through holes is provided with the spring resettlement groove on mesochite and the shell, the spring resettlement groove is provided with the outside bumping post from inside to outside, steel ball and steel ball spring, steel ball spring one end presses closer the spring resettlement groove sidewall other end and presses closer steel ball, steel ball presses closer the outside bumping post, the outside bumping post presses closer the inner edge bumping post, the inner edge bumping post presses closer verso sheet and recto sheet, in the time of in the inner edge bumping post inserts the slot that is distributed with on verso sheet main body and the recto sheet main body, inner edge bumping post and outside bumping post just all enter in the mesochite, when inner edge bumping post disengaging slot withstands on other positions of verso sheet and recto sheet, the inside wall that the rear end of outside bumping post enters spring resettlement groove Inner Front End and mesochite maintains an equal level, and the rear end of inner edge bumping post and lock core lateral wall maintain an equal level.
The utility model also provides the I-shaped key with above-mentioned tapered end coupling, one side of the metal insert of key has the first lock tooth row and the second lock tooth row that homonymy distributes, the first lock tooth row is different with the profile of tooth of the second lock tooth row, the first lock tooth row is arranged at the upper strata, the second lock tooth row is arranged at lower floor, the opposite side of metal insert has the first lock tooth row and the second lock tooth row, and wherein the second lock tooth row is arranged at the upper strata, and the first lock tooth row is arranged at lower floor.
Because the utility model provides the page or leaf sheet of tapered end to comprise the verso sheet and the recto sheet of overlapping setting, be provided with leaf spring between the left spring block piece of verso sheet and recto sheet and the right spring block piece, therefore just requiring on the key during release, the first lock tooth row of layer one side mates with the verso sheet, and second lock tooth row of key lower floor opposite side and recto sheet coupling, comparing the lock tooth and the page or leaf sheet that require the release coupling with traditional tapered end increases, and then can increase the release difficulty, strengthen the safety guarantee performance.And have slot on the page or leaf sheet of the tapered end that provides of the utility model, as long as adaptive key inserts in the lock core, push verso sheet and recto sheet simultaneously open, make the spring resettlement groove on the effect disengaging lock housing that just can make the outside bumping post be subjected to steel ball spring in the inner edge bumping post insertion slot, and then key can be rotated finally begin lock, this structure has increased the difficulty of picking lock, strengthens the safety guarantee performance of tapered end.Mesochite and lock core can relatively rotate in the utility model in addition, when inner edge bumping post disengaging slot withstands on other positions of verso sheet and recto sheet, the inside wall that the rear end of outside bumping post enters spring resettlement groove Inner Front End and mesochite maintains an equal level, the rear end of inner edge bumping post and lock core lateral wall maintain an equal level, outside stuck mesochite of bumping post and shell, rotational lock core can't drive mesochite (mesochite rotates just can open lock), lock core can only ad infinitum dally, general is not that adaptive key is lived lock core surely than difficulty, thereby can force the difficulty of picking lock, strengthen the safety guarantee performance.
