Abstract
The utility model discloses a primary-secondary pin cam slot anti-theft lock which mainly solves the problem that an existing cam slot lock is poor in anti-theft performance. The primary-secondary pin cam slot anti-theft lock is characterized in that a cam core is a cylinder provided with a stepped through hole, a boss is arranged on the outer wall of the cylinder, a groove matched with the boss for use is formed in the inner hole, a transverse groove matched with the boss for use is formed in one end face of a main lock cylinder, one part of the boss is arranged in the groove, and the other part of the boss is arranged in the transverse groove. According to the primary-secondary pin cam slot anti-theft lock, a cam and the main lock cylinder can not rotate relative to each other, when rotation of the main lock cylinder is not unlocked, technical unlocking can not be achieved through the cam which is driven by rotation of the cam core, and the anti-theft performance is improved.
Description
Technical field
The utility model relates to lock technology field, is specifically related to primary and secondary pearl curved groove theftproof lock.
Background technology
Lock is a kind of placing on the able to turn on or off implements, the fastener of opening with key, and from ancient times to the present, lockset is guarded the safety of we and property always.At present, primary and secondary pearl curved groove theftproof lock lock is requisite a kind of anti-theft tool during people live, a kind of primary and secondary pearl curved groove theftproof lock, include lock body, described lock body is provided with main lock body and auxiliary lock body and is situated between and is cast into integral structure, described main lock body inside is provided with main lock core, described auxiliary lock body inside is provided with auxiliary lock core, cam and cam core are established in the junction between described main lock core and the auxiliary lock core, described cam core places in the cam, and cam core one end contacts with main lock core, and the cam core other end contacts with auxiliary lock core, described cam core and main lock core can relatively rotate, and described cam core and main lock core joint one end face are provided with a translot simultaneously.When above-mentioned primary and secondary pearl curved groove theftproof lock runs into the technical unlocking formula, unlocking tool was kept away main lock core, was not rotating under the main lock core situation, can directly drive cam by the direct rotating cam core of translot on the cam core, cause release, and theftproof performance is poor.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of theftproof performance high primary and secondary pearl curved groove theftproof lock.
The technical scheme that the utility model adopted: a kind of primary and secondary pearl curved groove theftproof lock, include lock body, described lock body is provided with main lock body and auxiliary lock body and is situated between and is cast into integral structure, described main lock body inside is provided with main lock core, described auxiliary lock body inside is provided with auxiliary lock core, cam and cam core are established in the junction between described main lock core and the auxiliary lock core, described cam is provided with the endoporus that matches with the cam core, described cam core places on the endoporus, cam core one end contacts with main lock core, the cam core other end contacts with auxiliary lock core, described cam core is provided with the cylinder of stairstepping through hole and is provided with boss at the cylinder outer wall in being, described endoporus is provided with a groove that matches with boss, described main lock core one end face is provided with a translot that matches with boss, a described boss part places in the groove, and boss another part places in the translot.Described cam and main lock core can not relatively rotate, and when main lock core is not opened under the rotation situation, skilled unlocking is can not drive cam by the rotating cam core cause release, improves theftproof performance.
Described cam in-core is provided with camshaft and camshaft spring, is with the camshaft spring on the described camshaft and places on the cam core in the through hole.
The beneficial effects of the utility model are: 1, described cam and main lock core can not relatively rotate, and when main lock core is not opened under the rotation situation, skilled unlocking is can not drive cam by the rotating cam core cause release, improves theftproof performance; When 2, unblanking, unlocking tool need withstand camshaft and offset the camshaft spring and produce spring force, increases the technical unlocking difficulty greatly.This primary and secondary pearl curved groove theftproof lock improves theftproof performance, for our person and property provides safety guarantee more.
