Anti-mutually-opening row piece type lockset as well as lock core and key thereof

Abstract

The invention discloses an anti-mutually-opening row piece type lockset as well as a lock core and a key thereof. The anti-mutually-opening row piece type lockset comprises the row piece type lock core and the key, wherein the lock core is provided with a plurality of lock plates; through holes allowing the key to penetrate are formed in the lock plates; a plurality of steps are arranged on a key pole of the key and arranged from low to high in sequence in the direction from the tail end of the key pole to a key handle; each step comprises a platform face and a stage face; a stopping chute is formed in at least one platform face of the key pole and extends in the insertion direction of the key pole, wherein one end of the stopping chute extends out of the platform face, and an opening is formed in the end; a stopping projection is arranged on the inner wall of the through hole of the corresponding lock plate and at the position corresponding to the stopping chute; and when the matched key is inserted in, the stopping projection on the lock plate slides into the stopping chute. Therefore, the matching number of the structure is increased, the mutually opening probability of such locksets can be lowered greatly, and the anti-theft performance of the product is improved; and the processing cost is lowered, and the market competitiveness of the product is improved.

Description

technical field [0001] The invention relates to the technology in the field of anti-theft locks, in particular to an anti-mutual opening row-type lock [0002] tools and their lock cylinders and keys. Background technique [0003] At present, the known improved structure of the row-type lock cylinder includes an outer sleeve, an inner sleeve, a plurality of locking plates and a plurality of elastic elements. The inner wall of the outer sleeve is axially spaced with a plurality of positioning grooves with the same number as the lock pieces, and the plurality of lock pieces and the plurality of elastic elements are arranged in the inner sleeve and rotate synchronously with the inner sleeve. Wherein, the tail ends of the plurality of elastic elements respectively abut against the rear of the inner sleeve, and the front ends of the elastic elements respectively push against the locking pieces. And the front end of the key matched with it is provided with the step from low to h...
