【Specific embodiment】

The utility model is a kind of anti-padlock for breaking interchangeable lock core structure, as shown in Figures 1 to 4, including lock body 1, is mounted in It latch hook 2, lock core structure 3, driving member 4 in the lock body 1 and is pushed to lock the locked component 5 of the latch hook 2 by driving member 4, Middle lock core structure 3 includes plug body 31, hoodle component 32, lock core crossbeam 33 and crossbeam trip bolt 34, plug body 31, bullet Pearl component 32 constitutes the lock core of padlock, this is consistent with current pad lock structure, operation principle, the difference is that in the lock The top and both sides of core main body 31 are covered with the protective lid for lock core 6 of inverted U, in the plug body 31 and the side of protective lid for lock core 6 Face is connected by lock core lock pin 7, and inner end is connected by lock core connecting plate 8 and lock core trip bolt 9；In the protective lid for lock core 6 Protective cover trip bolt 10 is screwed in the threaded hole 61 of upper surface, inner end is withstood in plug body 31；The lock body 1 is in face The protective cover trip bolt via 11 passed in and out for the protective cover trip bolt 10 is provided on the position of the threaded hole 61；Positioned at lock Retaining spring 20 is equipped in that section of protective cover trip bolt via 11 between hook lock 12 and lock core hole 13 on body 1 successively With positioning bead 30；It is provided on the latch hook 2 and falls on locating slot 21 therein for 30 outer end of the positioning bead；The lock body 1 is in place Protective cover lockpin hole 14 is additionally provided on position between the hook lock 12 and lock core hole 13；It is filled in the protective cover lockpin hole 14 There is return spring 40, act on positioning pin 50 and protective cover lock pin 60 on 40 both ends of return spring；It is protected in the lock core The outer end that lockpin hole 62, at this moment positioning pin 50 on the lock core crossbeam 33 are withstood on after being fallen into for protective cover lock pin 60 is provided on lid 6 It is withstood on respectively on latch hook 2 and the lock core crossbeam 33 with the inner end of protective cover lock pin 60, it is preferable that in the protective cover lock pin 60 Equipped with blind hole 601, the positioning pin 50 and return spring 40 are placed in the blind hole 601, pass through positioning pin 50 and return in this way Spring 40 is ensconced in blind hole, the outer end of only positioning pin 50 is exposed and withstood on latch hook 2, so that it may so that lock body it goes without doing so Height, and then save the material cost of lock body.

From the aforegoing it can be seen that due to passing through protective cover trip bolt 10, protective cover on the vertical direction of protective lid for lock core 6 The dual protective lid for lock core that is fixed against of lock pin 60 comes off, and passes through lock core connecting plate 8, lock core trip bolt 9 from lateral pair Weight fixed lock core main body 31 and lock core crossbeam 33 and by lock core lock pin 7 from longitudinal direction by plug body 31 and lock core crossbeam 33 It connects together, thus can prevent lock core from coming off in three directions, so as to greatly strengthen the anti-drawing performance of lock core；Separately Outside, padlock extracts latch hook 2 in opening from the hook lock 12 of lock body 1, then by positioning bead 30, retaining spring 20, return Position spring 40 and positioning pin 50 unscrew protective cover trip bolt 10 after taking out, and then hold up lock body to make its lock core hole 13 Downward, entire lock core structure 3 can thus be taken out, and then takes out the lock core lock pin 7 of the vertical, horizontal on lock core structure 3 With lock core trip bolt 9, lock core next can be replaced（Its hoodle component by plug body and Qi Nei forms）, more Remaining parts of padlock can be still continuing with when changing, and can thus greatly save the cost for changing lock, therefore this practicality is new The more reasonable structure of type can prevent breaking and changing lock core, and the cost for changing lock core is low.

Interchangeable screw 70 is screwed in the outer end of hole of the protective cover trip bolt via 11, inner end snaps onto the latch hook In 2 locating slot 21, when lock core to be replaced, in opening, first interchangeable screw 70 to be back-outed after coming, then latch hook is pulled out Go out, then can just replace lock core as before.The locating slot 21 of latch hook 2 can also play the role of improving anti-theft, because In the state of locking a door, when attempting to want to pull out latch hook such as undesirable, to be just easy to that latch hook is made to break at positioning groove location, It thus can not violence unlocking.

In padlock, locked component 5 to latch hook 2 to lock or unlock principle, structure roughly the same.In the present embodiment, As shown in Figures 1 to 3, locked component 5 includes stop lock pin 51 and more hoodles 52 form, and is equipped in 2 inner end of latch hook for being somebody's turn to do The lock slots 22 that 51 outer end of stop lock pin is fallen into；Certainly, hoodle can change pin etc. into.

Although the utility model is described in detail with reference to above example, by the disclosure for people in the art Member is not it is readily apparent that and departing from the principle of the utility model and the situation of scope that the claim limits Under, the utility model can be made a variety of changes or be changed.Therefore, the detailed description of the embodiment of the present disclosure is only used for explaining, and The utility model is not intended to limit, but is defined by the subject-matter of the claims the range of protection.
