Fig. 7 A, 7B, 7C are respectively the action schematic diagrames that the utility model is opened into diverse location.

Please consult Fig. 1 earlier to shown in Figure 3, the utility model lockset is made up of a tapered end (1) and a locking bolt (2), wherein tapered end (1) comprises that two shells (10) (10 ') are involutory and forms a closure casing, be provided with a runner (3) therebetween, its outside tooth portion (31) agrees with mutually with the tooth portion (21) of locking bolt (2), in addition be provided with symmetrical locking structure, to unblank as control or the mechanism of locking state in the inside of two shells (10) (10 ').Because of two locking structural similarities, so only the internal construction of a side shell 10 is described in detail.Extremely shown in Figure 5 as Fig. 2.

The locking structure includes a knob (11), a core (12), a gate ring (13), and utilizes a retainer ring (14) that each member is incorporated into the inside of shell (10), and the outer end of knob (11) is exposed for rotation.Wherein the inner outer rim of knob (11) is provided with several recess (111), and forms several protuberances (112), and setting wherein a place, to have long distance be location division (113).Be provided with an elastic steel ball (101) in addition in the inside of shell (10), make steel ball (101) be butted on the inner outer edge surface of knob (11).Therefore when rotation, contact with the surface of protuberance (112) down at recess (111), the user can feel that each positioning of rotating of knob (11) concerns.Again, the inner endoporus of knob (11) is made as polygonal, and core (12) is to be arranged in it, and the inner of core (12) is made as cant column (121), appropriate location in this cant column (121) is provided with a groove (122) in addition, is extended the flange piece (124) that is provided with a semicircle by its endoporus (123).Gate ring (13) is located between knob (11) and the retainer ring (14), and it is provided with the tongue (131) that side direction is protruded, and its endoporus also is a polygonal, to match with the cant column (121) of core (12).Be provided with a clip (141) that extends to the center in retainer ring (14) in addition, its size is to be as the criterion with involutory groove (122) on cant column (121).One clamping block (15) is hubbed on the axle center (102) on the inner casing (10), and its fastening end (151) extends to tooth portion (31) position of runner (3), and it is held in addition and is dog point (152), is positioned at the outer fringe position of gate ring (13); The top of fastening end (151) is provided with a little spring (153), and it is placed in the inner spring groove (103) of shell (10), and it can provide elastic force, makes fastening end (151) have the elasticity trend that the top is formed on runner (4).Another spring (4) is to be installed in core (12) endoporus (123), and it is held in addition and also is contained in the endoporus of relative core, and an elastic force is provided, and makes two cores be the state of outwards opening.

During operation, the user rotates knob (11), and interlock core (12) and gate ring (13) when the tongue (131) of gate ring (13) moves to dog point (152) position of clamping block (15), as shown in Figure 5, can make fastening end (151) break away from runner (3).And when two groups of locking structures all moved to this state, runner (3) no longer was subjected to blocking, but formed free rotation state, so locking bolt (2) is just pulled out, reached the purpose of unblanking.

Shown in Fig. 4,5, because of clamping block (15) mainly is restriction runner the turning clockwise of (3), and that it is rotated counterclockwise is not limited, so locking bolt (2) can at any time penetrate tapered end (1), and formation locking state.And when unblanking, the user can utilize the male and fomale(M﹠F) of the inner outer rim of knob (11), cooperate elastic steel ball (101), longer displacement with location division (113) is reference point, as shown in Figure 6, feels the formed turn of each male and fomale(M﹠F) position again, remember its order, promptly need not to establish with digital number in addition and distinguish in knob (11) outside, and make other people be difficult to know wherein profound, to reach antitheft splendid effect.

Please consult Fig. 7 A again, shown in the 7C, under the most state, the flange piece (124) (124 ') of two cores (12) (12 ') is staggered state, and core can't be pressed down, have only when two flanges sheet (124) (124 ') is the complimentary positions of opposition, core can be pressed into to central authorities, as Fig. 7 B, shown in the 7C, after being pressed into, rotate knob (11), because of it temporarily separates with the cant column (121) of core (12) and forms idle running, and change the relative position of this knob (11) and core (12), also reach the desired location that change is unblanked simultaneously, then make it recoil to the home position, thereby obtain Expected Results of the present utility model as long as decontrol core (12).

In sum, the utlity model has novelty, creativeness, practicality, meet novel patent requirement, so file an application in accordance with the law.
