The specific embodiment

Below in conjunction with accompanying drawing the structural principle and the principle of work of the utility model are done concrete description: a kind of brake lock of the utility model; Comprise housing 2, brake disc 1, lock core 8, locking bar 3 and brake disc lockhole 11; Lock core 8 tops are provided with eccentric shaft 7; Eccentric shaft 7 is arranged on the arm-tie on flat type arm-tie 6 tops in the through hole 62, and through hole 62 is horizontal " one " font and corresponding with eccentric shaft 7 on the arm-tie; Arm-tie 6 is " L " type, and arm-tie 6 bottoms are provided with and locking bar 3 corresponding arm-tie lower through-holes 61; Locking bar 3 is cylindric, and its underpart is provided with ring-type salient 10; Locking bar ring-type salient 10 diameters are greater than arm-tie lower through-hole 61 internal diameters; Housing 2 inboards are disposed with directing plate 4 and limit base 5 downwards along lock core 8, be respectively equipped with on the directing plate 4 with locking bar 3 corresponding first through holes 41 and with arm-tie 6 corresponding mounting holes, limit base 5 is provided with and said locking bar 3 corresponding second through holes 51; Locking bar 3 tops and 41 sockets of first through hole, locking bar 3 bottoms downwards successively with arm-tie lower through-hole 61 and 51 sockets of second through hole; Between directing plate 4 and locking bar ring-type salient 10, locking bar 3 is socketed with stage clip 9, and arm-tie 6 also is socketed in the jack hole, thereby guiding locking bar 3 can only move by above-below direction; The corresponding brake disc lockhole 11 in locking bar 3 lower ends, locking bar also can be arranged to flat-shaped as required.

When needing the lock car, brake disc lockhole 11 is left in these hour locking lever 3 bottoms, and first key inserts in the lock core 8; Screw key, lock core 8 rotate and drive eccentric shaft 7 rotations, and then drive arm-tie 6 moves downward; Under the elastic force effect of stage clip 9; Locking bar 3 moves down, and is inserted in the brake disc lockhole 11, accomplishes lock car process.

When unblanking, brake disc lockhole 11 is inserted in these hour locking lever 3 bottoms, and first key inserts lock core 8; Key, lock core 8 are rotated and are driven eccentric shaft 7 rotations, and then drive arm-tie 6 upward movements; The arm-tie lower through-hole 61 of arm-tie 6 is holding in the palm ring-type salient 13 upward movements of locking bar 3 lower ends; Thereby drive locking bar 3 upward movements, brake disc lockhole 11 is left in locking bar 3 lower ends, and brake lock is opened.

Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
