Abstract
The utility model discloses a single unlocking cylinder. The existing single unlocking cylinder is relatively poor in safety, and can not achieve the purpose of safety. The single unlocking cylinder comprises a cylinder casing, an outer lock plug, a cylinder cam and an inner lock plug, wherein the outer lock plug, the cylinder cam and the inner lock plug are mounted on the cylinder casing. The single unlocking cylinder is characterized in that an anti-shifting driving component which is always in driving connection with the outer lock plug is arranged between the cylinder cam and the outer lock plug, after the anti-shifting driving component penetrates through the cylinder cam, a return spring is mounted between the anti-shifting driving component and the inner lock plug, the inner lock plug and the cylinder cam are always in driving connection, when under work state, the anti-shifting driving component and the cylinder cam are in driving connection, and when under normal state, the anti-shifting driving component and the cylinder cam are not in driving connection. The utility model enables thieves not to be capable of driving the cylinder cam to rotate by a self-made special tool and not to be capable of unlocking, thereby increasing the safety of the cylinder.
Description
Technical field
The utility model relates to lockset, specifically a kind of head of singly unblanking.
Background technology
The unfolding mode of head of singly unblanking is: at the indoor knob that can directly be rotatably installed on the internal cylinder power transmission shaft, rotate internal cylinder, reach the purpose of unblanking; Outdoor, need by supporting key unlocking.The safety of the present head of singly unblanking is relatively poor, its outdoor except with technical opening, also can insert from keyhole by the homemade special tool of thief, stir internal cylinder or tapered end cam, make its rotation, the rotation of internal cylinder or tapered end cam drives the rotation of outer lock core, thereby realizes unblanking, and does not reach purpose of safety.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of anti-transfer slip head of unblanking is provided, and makes the thief utilize homemade special tool to unblank, to improve the safety of tapered end.
For this reason, the utility model adopts following technical scheme: the anti-transfer slip head of unblanking, comprise tapered end shell and the outer lock core, tapered end cam and the internal cylinder that are installed on the tapered end shell, it is characterized in that being provided with between described tapered end cam and the outer lock core one and be in the anti-transmission component of dialling that is in transmission connection all the time with outer lock core, described anti-group transmission component runs through behind the tapered end cam and a return spring is housed between the internal cylinder, internal cylinder and tapered end cam are in all the time and are in transmission connection, internal cylinder is freely rotated the control that is not subjected to outer lock core, has realized that the tapered end list opens function; In working order (when promptly inserting key), anti-group transmission component and tapered end cam are in and are in transmission connection, key inserts when putting in place, all pellets shot from a slingshot cooperate with key tooth flower, key is freely rotated outer lock core, realization is unblanked, (when promptly not inserting key) under normal conditions, the anti-transmission component of dialling is in transmission connection with the tapered end cam disengages under the effect of return spring, insert along the keyhole on the outer lock core as special tool that will be more tiny, when attempting to stir internal cylinder or directly stirring the tapered end cam, this instrument must be by anti-gap and anti-gap of dialling between transmission component and tapered end cam of dialling between transmission component and outer lock core endoporus, because of anti-gap minimum (generally about 0.15mm) of dialling between transmission component and tapered end cam, make the insufficient strength of insertion instrument, can't drive internal cylinder or tapered end cam rotation, even instrument can drive the tapered end cam rotation, instrument will rotate around anti-dialling on the transmission component after rotating smaller angle, because of the anti-transmission component of dialling keeps drive connection with outer lock core all the time, outer lock core is not having under the key situation and can not rotate, thereby cause instrument can not continue to drive the tapered end cam rotation, can't unblank.
As the further of technique scheme improved and replenish, the utility model is taked following technical measures:
The above-mentioned anti-transfer slip head of unblanking, the anti-transmission component of dialling comprises transmission locating shaft and the anti-driving member of dialling that is enclosed within on the transmission locating shaft, anti-dialling in the driving member is provided with a spring that is enclosed within on the transmission locating shaft, the head of transmission locating shaft has an annular groove, the opening card that clamping one is conflicted and dialled the driving member end face anti-on the annular groove, make the anti-driving member location of dialling, the anti-driving member of dialling is provided with locating piece, have a through hole that can be used with locating piece on the tapered end cam, groove on locating piece and the outer lock core end face is in all the time and is in transmission connection, in working order down, the key that inserts places in the through hole of tapered end cam the part of locating piece, locating piece is set up interim drive connection with the tapered end cam when keeping drive connection with outer lock core, the rotation of outer lock core drives the rotation of tapered end cam, realizes unblanking; Under normal conditions, locating piece breaks away from through hole under the effect of return spring, and the rotation of internal cylinder is not subjected to the control of outer lock core, and is free to rotate, and realization tapered end list is opened.
The above-mentioned anti-transfer slip head of unblanking, locating piece has two, is to be symmetrical arranged, and two locating pieces make that anti-to dial the driving member working stability reliable.
The above-mentioned anti-transfer slip head of unblanking is provided with convex tendon near the tapered end flank of cam of internal cylinder, and convex tendon and through hole shift to install, and the groove on described convex tendon and the internal cylinder end face is in all the time and is in transmission connection, the rotation drive tapered end cam rotation of internal cylinder.
The utlity model has following beneficial effect: make the thief utilize homemade special tool can not drive the tapered end cam rotation by the anti-transmission component of dialling, can't unblank, improved the safety of tapered end; Freely rotating of internal cylinder do not influence outer lock core and the anti-transmission component of dialling, and Stability Analysis of Structures is reliable.
Below in conjunction with specification drawings and specific embodiments the utility model is further described.
