The specific embodiment is described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.

A kind of door lock that easily changes as depicted in figs. 1 and 2, comprises lock body 1, lock core 2, and described lock body 1 comprises the locking component 3 of shell 12 and Qi Nei, on the described lock core 2, vertically inwardly opens symmetry along end face thereafter and offers two screws 21; Offer two circular holes of aiming at described two screws 21 13 on the bonnet of described shell 12; During installation, earlier lock body 1 is fixed on the inner surface of door 8, then with lock core 2 from inserting through the door lock hole outdoors, through described circular hole 13 to screw 21 lock core 2 is fixed from shell 12 bonnets by two screws 6 again.

As shown in Figure 3, Figure 4, described locking component 3 comprise two guide rods that be arranged in parallel 31, be fixed on the dead bolt 32 of described guide rod 31 front ends, vertically connect two dead bolts, 32 tail ends cross bar 33, withstand cross bar 33 and be sleeved on bung flange spring 36 and rotating shaft 34 on the guide rod 31; Be connected with trace 35 between one end of described cross bar 33 and the rotating shaft 34, this trace 35 is made up of stock 351 and quarter butt 352 two parts, thereby hinged making between the two can relatively rotate between described stock 351 and the quarter butt 352, the other end of described stock 351 and cross bar 33 are hinged, and the other end of described quarter butt 352 is fixed in the rotating shaft 34.When described door lock was lock-out state, as shown in Figure 3, described stock 351 was straight line with quarter butt 352, and promptly trace 35 is an angle ejector rod and withstands cross bar 33, and 32 withdrawals of restriction dead bolt improve the theftproof performance of door lock effectively; When unblanking, the inserted sheet of lock core 2 rotates described rotating shaft 34, and described then quarter butt 352 rotates, and drives cross bar 33 by stock 351 again and makes in the dead bolt 32 indentations lock.

In the utility model, described quarter butt 352 can be one-body molded with rotating shaft 34.

As shown in Figure 1, 2, the utility model easily changes door lock and also includes indoor Unlocking knob 5, and the handle of this knob 5 is arranged between described two circular holes 13.

In the utility model, locking component 3 in the lock body 1 also can be designed to multiple structure, as long as satisfy following condition: two screws 6 from the lock body bonnet enter the screw 21 that runs through behind the lock body 1 again on the described lock core 2 of precession and with lock core 2 fixing after, described two screws 6 can not hinder the locking or the unlocking action of locking component 3; It also is the position that the design of locking component 3 must spatially reserve described two screws 6.Locking component 3 of the present utility model adopts designs such as relatively turnable trace 35 of two segment types and cross bar 33, is most preferred embodiment of the present utility model, running through of two screws 6 is reserved optimal spatial dexterously; Improved the theftproof performance of door lock simultaneously effectively from the mechanics angle.
