Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 7.
An anti-violence mechanism for an intelligent lock cylinder comprises an outer lock body 1 and an inner lock body 2, wherein a thumb wheel 3 is arranged between the outer lock body 1 and the inner lock body 2, a key inserting end is arranged on the outer lock body 1, a handle part 4 is arranged on the inner lock body 2, the inner lock body 2 comprises an inner lock shell 20, an inner lock sleeve 21 penetrates through the inner lock shell 20, one end of the inner lock sleeve 21 extends into the thumb wheel 3, an extension sleeve 22 is arranged on the other end of the inner lock sleeve 21, the cross section of the extension sleeve 22 is smaller than that of the inner lock sleeve 21, the handle part 4 comprises a rotating handle 40 and a linkage part 41, a blocking part 42 is arranged on the linkage part 41, a through hole for the extension sleeve 22 to penetrate through is formed in the blocking part 42, an elastic part 5 is sleeved on the extension sleeve 22, one end of the elastic part 5 abuts against the blocking part 42, the other end of the elastic part abuts against the inner lock sleeve 21, a plurality of limiting holes 210 are formed in one end, close to the extension sleeve 22, of the inner lock sleeve 21, the limiting holes 210 are circumferentially distributed along the outer surface of the inner lock sleeve 21, a sliding groove 200 is formed in the inner wall of the inner lock shell 20, a telescopic limiting part 6 is arranged in the sliding groove 200, and the limiting part 6 can be inserted into the limiting holes 210 of the inner lock sleeve 21.
