Detailed Description
The invention will be further described with reference to the following detailed description of embodiments, with reference to the accompanying drawings, in which figures 1-6 show:
the utility model provides a lock core prevents boring structure, includes lock core main part 1, and the lock core main part in the drawing is the sketch map, the tip cover of lock core main part 1 is equipped with prevents boring cover 2, prevents boring cover 2 and is provided with hole site 21 and supplies the key to stretch into in lock core main part 1, the tip week side of lock core main part 1 is provided with two at least elastic bulge 3, the week side of preventing boring cover 2 is provided with bordures 22, prevents boring cover 2 including borduring 22 with the tip parcel of lock core main part 1, and the tip of borduring 22 is inwards forming anticreep wall 23, and elastic bulge 3 is spacing in borduring 22 to prevent boring cover 2 can't break away from the tip of lock core main part 1 under the effect of antic. The anti-drilling cover 2 forms an annular inner groove through the end face of the anti-drilling cover, the edge 22 and the anti-falling wall 23, the elastic bulge 3 is tightly clamped in the annular inner groove by the annular inner groove, so that the anti-drilling cover 2 is installed at the end part of the lock cylinder main body 1, and the elastic bulge 3 is partially positioned in the lock cylinder main body 1 and partially limited in the annular inner groove, so that the anti-drilling cover 2 cannot be separated after the installation is finished, and the structural stability of the anti-drilling cover 2 is ensured. And the structure that the elastic bulge 3 is arranged in the annular inner groove enables the anti-drilling cover 2 to rotate freely
At least two elastic bulges 3, preferably two elastic bulges 3, are uniformly arranged on the peripheral side of the lock cylinder body 1, a spring 31 is arranged at the rear part of each elastic bulge 3, and each elastic bulge 3 extends towards the peripheral side of the lock cylinder body 1 by the spring 31. The side wall of the lock cylinder main body 1 is provided with a mounting position 13, the spring 31 and the elastic bulge 3 are arranged in the mounting position 13, and the spring 31 gives a force to the elastic bulge 3 to be far away from the mounting position 13. The mounting position 13 is a blind hole. The mounting position 13 is the mounting position of the spring 31 and the elastic protrusion 3, and is also the positioning position of the elastic protrusion 3, when the anti-drilling cover 2 is mounted at the end of the lock cylinder main body 1, under the action of the spring 31, the part of the elastic protrusion 3 extends out of the mounting position and is limited in the edge covering 22, and the extending part of the elastic protrusion 3 can not be separated from the edge covering 22 under the action of the anti-dropping wall 23.
