But indoor for some, people needs on the common door of frequent switch turnover, such as washroom, bedroom, study etc., as long as guarantee that Men Buhui opens automatically or opened by mistake, re-use and need key switch, baroque theftproof lock just improper, cost is high too.Those ornamental swing handle door locks do not have lockset function, and pin lock is economical and practical, easy to use but profile is not attractive in appearance.To sum up total total, be necessary current technology to improve, with provide a kind of can be rational in infrastructure, the interior door lock that cost is lower, easy to use.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of structure of simple in structure, easy to use, false lock core that cost is lower is provided.
For achieving the above object, the utility model is by the following technical solutions:
The structure of a kind of false lock core described in the utility model, comprise the fixture one, spring bolt mechanism and the fixture two that set gradually, on described fixture one, be equipped with rotating mandrel, on fixture two, be equipped with rotating knob, fixture one is equipped with on fixture two fixed mechanism being connected with outer panels in door lock; Described spring bolt mechanism is provided with the driving lever with its interlock, and driving lever two ends are in transmission connection with mandrel and knob respectively.
Further, described fixed mechanism comprises joint and leaf spring, and two joints are connected with the medial surface of fixture one, fixture two respectively; In the outer rim of joint, have annular groove, take the shape of the letter U structure setting and then be connected on annular groove of leaf spring.
Further, the both sides bottom land of described annular groove is provided with the cross section coordinating with leaf spring.
Further, described mandrel outer end has keyhole, and mandrel inner end has the connecting hole one coordinating with driving lever, and the inner end of knob has the connecting hole two coordinating with driving lever.
Further, described spring bolt mechanism comprises dead bolt and roller, the dead bolt structure setting that takes the shape of the letter U, and two spikes of dead bolt are hinged with roller respectively; The outer rim of described roller is provided with the shifting block that promotes dead bolt rotation, driving lever be arranged on roller and with its interlock.
The utility model beneficial effect is: the utility model compactness rational in infrastructure, meet the normal locking functions of interior door and avoid being opened by mistake, only need decoration key to open when open the door in outside, inner unlatching passed through knob, simplify overall structure, reduced production and application cost.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The structure of a kind of false lock core described in the utility model, comprises the fixture 1, spring bolt mechanism and the fixture 2 20 that set gradually, and fixture 1 is equipped with on fixture 2 20 fixed mechanism being connected with outer panels in door lock; Fixed mechanism comprises that joint 12 and 13, two joints 12 of leaf spring are connected with the medial surface of fixture 1, fixture 2 20 respectively; In the outer rim of joint 12, have annular groove 14, take the shape of the letter U structure setting and then be connected on annular groove 14 of leaf spring 13, fixture 1 is placed in the outside of door lock outer panels, joint 12 is conflicted with the hole of button edge of outer panels through door lock outer panels and annular groove 14, leaf spring 13 is connected in annular groove 14 and coordinates and be clamped in outer panels with fixture 1, and then makes fixture 1 on panel, axial displacement not occur outside; Fixture 2 20 is fixing like this too on door lock wainscot.
The both sides bottom land of above-mentioned annular groove 14 is provided with the cross section coordinating with leaf spring 13, conflicts with panel respectively in the upper and lower end face of leaf spring 13, and then locking fixture 1 does not produce rotation radially on panel.
In above-mentioned fixing piece 1, be equipped with rotating mandrel 11, be equipped with rotating knob 21 on fixture 2 20, described spring bolt mechanism is provided with the driving lever 40 with its interlock, and driving lever 40 two ends are in transmission connection with mandrel 11 and knob 21 respectively; Mandrel 11 outer ends have keyhole 16, and mandrel 11 inner ends have the connecting hole 1 coordinating with driving lever 40, and the inner end of knob 21 has the connecting hole 2 22 coordinating with driving lever 40; Driving lever 40 two ends are inserted in connecting hole 1 and connecting hole 2 16, and then synchronous interaction between mandrel 11, driving lever 40, knob 21 threes, and when the interior insertion decoration key of keyhole 16 twisting, mandrel 11 drives driving levers 40 and knob 21 to rotate; When 21 drive driving levers 40 of turning knob and mandrel 11 rotations.
