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 simple in structure, easy to use, single core knob lock core that cost is lower is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of single core knob lock core described in the utility model, comprise the fixture one, spring bolt mechanism and the fixture two that set gradually, described fixture one is provided with key operated lock core, on fixture two, be equipped with rotating knob, fixture two inner sides are provided with the fixed mechanism being connected with Door lock casing; Described spring bolt mechanism is provided with the driving lever with its interlock, and driving lever two ends are in transmission connection with lock core and knob respectively.
Further, described fixed mechanism comprises joint and leaf spring, and joint is located on the medial surface of fixture two; 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 lock core inner end is provided with the splined hole coordinating with driving lever, and the inner end of knob has the connecting hole 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 is simple and reasonable, meet the normal locking functions of interior door and avoid being opened by mistake, need to be key operated when monolock cored structure externally opens the door, inner unlatching only needs knob, simplify overall structure, reduce production and application cost.
