Also be provided with the main spring that eject the reverse cylindrical structure of compressing lock core bottom between said cylindrical structure and the lock core; A corresponding little top axial stopper slot, the said little top movement length that is limited in the stopper slot and controls the relative lock of lock core of being provided with on the said cylindrical structure;
On earth the time, the terminal push rod of said lock core is stuck in outside the through hole in the lock core compressing main spring retraction cylindrical structure, and the position is provided with draw-in groove corresponding big top this moment on the said cylinder, and said big top upspringing is arranged in the draw-in groove little top being hidden in the lock core;
After coupling is inserted key turns 90 degree in the said lock core, said big top being hidden in the lock core, said little top the ejection in stopper slot, the lock core playback protrudes in outside the cylindrical structure under the main spring effect, and the push rod on the lock core is hidden in the lock.
Further simplify structure, be provided with a cam hole in the said shell fragment, said lock core pivotable parts end is provided with a cam, and said cam is located in the cam hole.Make cam and cam hole coupling realize that lock core control shell fragment moves up and down, and facilitates the top corresponding sports of size like this.
The utility model is installed in lock on the passing door in use, and lock core protrudes in outside the cylindrical structure under the main spring effect at the beginning, in the push rod retraction lock.On the shell fragment on the big top inwall that is subject to cylindrical structure, make toply outstandingly to be fastened on stopper slot and to play position-limiting action, the extension elongation of the relative cylindrical structure of control lock core for a short time; When after the compressing lock core is gone into cylindrical structure, arriving the precalculated position, big top running into is opened in the locational draw-in groove of cylinder ends, described big top being absorbed in the draw-in groove, and push rod stretches out in to snap in the lock in the predetermined stay hook of passing on the door and plays the locking effect.
After coupling is inserted key turns 90 degree in said lock core; Said shell fragment is driven by the pivotable parts on the lock core, big top the contraction in lock core, said little top stretching out in the stopper slot; Under the main spring effect lock core playback outstanding with cylindrical structure outside; Push rod on the lock core is hidden in the lock, plays the release effect, passes door and just can open.
The beneficial effect of the utility model is: provide can being convenient to use at band of a kind of novel structure to collude passing door upper prop lock, can realize the function of lock with lower cost.

Fig. 3 and Fig. 4 are the utility model shell fragment overhead cam and cam hole structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
In conjunction with accompanying drawing 1 to 4; A kind of linkage post lock, its lock core is a blade construction, described linkage post lock comprises a lock 1; A cylindrical structure 2 is arranged on the said lock 1; Cylindrical structure 2 bottoms offer a through hole, are slidingly equipped with lock core 3 in the said cylindrical structure, and said lock core end is provided with a push rod 4 and also can passes along with the slip of lock core outside the lock 1 over against through hole;
Said lock core is provided with a shell fragment 5 that receives lock core control; Described shell fragment 5 upper ends have one big by top 6; The lower end have one little by top 7; Said big top 6 eject with one of little top 7 same time that another then is hidden in the lock core 3 outside lock core, and shell fragment is provided with spring 8 and makes to have the big top trend that ejects outside lock core under the shell fragment normality;
Also be provided with the main spring 9 that eject compressing lock core 3 reverse cylindrical structures 2 bottoms between said cylindrical structure 2 and the lock core 3; Corresponding little top 7 are provided with an axial stopper slot 10 on the said cylindrical structure 2, and said little top 7 are limited in the stopper slot 10 and control the movement length of lock core 3 relative locks 1;
