Description

Locking core cabable for change key

The utility model belongs to a kind of novel lock core, is widely used in the field that various needs such as door lock, cabinet lock, drawer-lock, padlock, vehicle lock use lockset.

The present lockset that uses, its lock core mainly contains two kinds of key formula lock core and coding type lock cores, the lock structure that the former forms is simply firm, strong security, but can only use a kind of fixing key, in case after key loss or the damage, this lockset is also just scrapped, and causes very big waste and inconvenience, and the lockset that the latter forms can arbitrarily be changed password by the user, but exist shortcomings such as complex structure, rapid wear, confidentiality are not strong, can't satisfy instructions for use.

The purpose of this utility model is to provide a kind of lock core that can arbitrarily be changed key by the user, its locking control is finished by one group of identical key with unlatching, wherein a slice key inserts in lockhole of this lock core, opening device is promptly locked, after in another lockhole of this lock core, inserting the identical key of a slice, locking promptly is disengaged, and realizes purpose of opening.When the user need change the key of this lock core use, only need with the identical key of another group change original that group of using or to the set of keys of original use with needle file or on Bitting machine equivalent change tooth depth or groove depth can realize, change very simple and convenient, this lock core lock hole and the replaceable use of open hole, enlarged the scope of application of lockset, the utility model has possessed the advantage of key formula lock core and coding type lock core simultaneously, and has overcome their shortcoming, has expanded the function of lockset.

Technical solutions of the utility model are as follows: it is made up of with control device for opening and opening device two large divisions locking, feature is that it has by front and back lockhole (9), (11) in control lever (6) horizontal segment and the lockhole body (10) common locking and the control device for opening of forming of contact lever (7), (8) and spring (12).Revolve spool (18) and the common opening device of forming of fixed screw (17) by control lever (6) vertical section, contact lever (1), pellet shot from a slingshot (5), spring (2), unlatching lock body (3), unlatching lock core body (4), unlatching axle (16), unlatching.Locking and control device for opening and opening device constitute lock core integral body by the connection of control lever (6).Front shroud (14), front trim panel (15), back shroud (13) constitute lock core shell jointly.

The utility model is simple in structure, and is reasonable in design, can adapt to the lockset of all size, can arbitrarily change key by user oneself, strengthened the confidentiality of lockset, cuts the waste, and expanded the function and the purposes of lockset.

Now the utility model is described in further detail in conjunction with the accompanying drawings:

Fig. 1, Fig. 2, Figure 3 shows that the utility model door lock core structural representation, wherein Fig. 1 is the internal construction schematic diagram that removes part front shroud and front trim panel, turning knob etc., and Fig. 2, Fig. 3 are sectional structure chart.

With reference to accompanying drawing, contact lever (1), (7), (8) a end can be in lockhole (9), (11), open lock body (3), open in the corresponding duct of lock core body (4) and move, other end fluting, bottom land central authorities protrude, control lever (6) is that its right side, vertical section upper end of special bending shape embeds in contact lever (1) groove, contact with the bottom land convex tip, the horizontal segment left end embeds in contact lever (7) groove, hinged with rivet each other, making control lever (6) can be that rotate in the axle center with the rivet, and its axle center can be moved along contact lever (7) axis direction, and its downside embeds in contact lever (8) groove after the back-shaped bending of horizontal segment right-hand member, contacts with the bottom land convex tip.Spring (2) makes pellet shot from a slingshot (5), contact lever (1) closely contact with control lever (6) vertical section, spring (12) makes contact lever (7) (8) closely contact with control lever (6) horizontal segment, by the connection of control lever (6), contact lever (7), (8) position, both ends are moved the position that can influence contact surface between contact lever (1) and the pellet shot from a slingshot (5) and are moved.Make unlatching and the lock out action that to control the opening device that constitutes by spring (2), pellet shot from a slingshot (5), contact lever (1), control lever (6), unlatching lock body (3), unlatching lock core body (4) by spring (12), lockhole body (10) contact lever (7), (8), lockhole (9), (11), the common locking that constitutes of control lever (6) and control device for opening, form lock core integral body jointly.

When all not inserting key in lockhole (9), (11), under spring (12) tension, contact lever (7), (8) lower end in lockhole body opening road bottom, at this moment, control lever (6) vertical section center line is on contact lever (7) axes extending line, at this moment, contact surface is in and opens between lock body (3) and the unlatching lock core body (4) on the contact surface between contact lever (1) and the pellet shot from a slingshot (5), unlatching lock core body (4) can freely be rotated, be in opening, this lock core is equivalent to one and rotarily opens switch.After in lockhole (11), inserting key, contact lever (8) lower end is upwards ejected a segment distance by key bit or groove, contact lever (8) upper end makes control lever (6) the horizontal segment right-hand member segment distance that moves up, because control lever (6) horizontal segment left end and contact lever (7) are that rivet is hinged, the pin joint invariant position, make control lever (6) the vertical section upper end skew origin-location angle that turns left, under spring (2) effect, pellet shot from a slingshot (5) is followed with contact lever (1) and is moved to the left a segment distance, contact surface no longer is in open between lock body (3) and the unlatching lock core body (4) on the contact surface, opening lock core body (4) can not rotate, and reaches the purpose of locking.When needing to open, only need in another lockhole (9), to insert another sheet key identical with key in the lockhole (11), make on the contact lever (7) and move, drive on control lever (6) the horizontal segment left end and move, because two key tooth depths or groove depth are identical, make each winding feeler lever (7), the distance of moving (8) is identical, and owing to moving along contact lever (7) direction of axis line control lever (6) center of rotation position, control lever (6) vertical section center line is come back on contact lever (7) axes extending line, simultaneously contact lever (1) and pellet shot from a slingshot (5) are moved right and compress spring (2), contact surface is got back to open between lock body (3) and the unlatching lock core body (4) on the contact surface, unlatching lock core body (4) can be rotated, be in opening, realize purpose of opening.When the key in lockhole (9), (11) is taken out a slice, control lever (6) vertical section no longer is on the axes extending line of contact lever (7), to contact lever (1) and pellet shot from a slingshot (5) contact surface no longer being in open between lock body (3) and the unlatching lock core body (4) on the contact surface, make unlatching lock core body (4) locked, after the key that takes out inserted again, open lock core body (4) and be in opening again, realize the random replacement of lockhole (9), (11) key lock and unlatching.As long as the key of use is identical in lockhole (9), (11), just can realize this lock core locking and open control, that is to say that the key of this lock core use can arbitrarily be changed by the user.
