Abstract

The invention relates to a novel mechanical lock core which consists of a main lock core, an assistant lock core and a linking device, wherein the linking device is arranged between main lock core and the assistant lock core; the rotation of the main lock core is limited by the assistant lock core through the linking device, so that the main lock core is limited by the assistant lock core in the rotating process; and only when the main lock core and the assistant lock core are in an unlocking state, the main lock core can be freely rotated without being limited by the assistant lock core. The novel mechanical lock core can be used for preventing technical opening.

Description

Novel mechanical lock core

Technical field

This patent belongs to mechanical lock core, relate to a kind of can be in case the novel mechanical lock core of technical unlocking.

Background technology

Aspect lockset, mechanical cylinder lock is the most widely used product always.Traditional cylinder lock is because simple in structure, and theftproof performance is the non-constant of performance of anti-technical opening particularly.In order to improve the theftproof performance of lockset, increase the difficulty of technical opening, people have designed various Anti-theft billiard locks.But these mechanical locks in various degree have a design defect, what have has just increased to a certain extent the difficulty of technical opening and can not reach the purpose of anti-technical opening; Although the purpose that can reach anti-technical opening that has, complicated manufacture craft has increased cost of manufacture, thereby can't extensively popularize use.

The patent of invention content

In order to overcome the poor deficiency of existing machinery lock theftproof performance, patent of the present invention provides a kind of novel mechanical lock core.Patent of the present invention had both kept the simple characteristics of traditional cylinder lock manufacture craft, can in case technical unlocking, greatly improve the theftproof performance of lockset again.

The technical scheme of patent of the present invention is as follows: a kind of novel mechanical lock core comprises main lock core, auxiliary lock core, linkage, pellet, spring.

Lock core is comprised of main lock core and auxiliary lock core, and auxiliary lock core is by the rotation of linkage restriction main lock core, and main lock core utilizes flip flop equipment to open or close lockset.

Along the main lock core surface one circle groove is set at the main lock core rear portion, groove is crooked to the main lock core rear portion near the part of auxiliary lock core, like this When main lock core when the main lock core axis rotates, the bending that utilizes groove promotes the auxiliary lock core edge by the interlock pellet The main lock core axis direction moves forward and backwardIf auxiliary lock core is not in released state then can limits the rotation of main lock core, just can't open lockset, only have when main lock core and auxiliary lock core are in released state simultaneously, main lock core just can unrestrictedly rotate, thus band driven triggering device opened lock tool.

After opening lockset, when main lock core went back to original position again, the bending that utilizes equally groove promoted auxiliary lock core by the interlock pellet and keeps in the center and put, and at this moment can extract smoothly key.

The beneficial effect of patent of the present invention is, the rotation of main lock core depends on not only whether main lock core is in released state, but limited by auxiliary lock core, and the unrestricted rotation of main lock core ability when only having main lock core and auxiliary lock core to be in released state simultaneously, thus reach the purpose of opening lockset.

The specific embodiment

Below in conjunction with drawings and embodiments patent of the present invention is further specified.

As shown in Figure 1, A kind of novel mechanical lock core comprises main lock core 1, auxiliary lock core 2 and linkage, linkage Formed by groove 3 and interlock pellet 4

Such as Fig. 2, shown in Figure 3, At the rear portion of main lock core 1 groove 3 is set, the top of groove 3 is near the section of auxiliary lock core 2 Divide to the rear portion of main lock core 1 crooked, utilize the bending of groove 3 and interlock pellet 4 to realize the interlock of main lock core 1 and auxiliary lock core 2, thereby make auxiliary lock core 2 play the effect of restriction main lock core 1 motion state.

As shown in Figure 4, the lockhole of main lock core 1, auxiliary lock core 2 and lock body sheath 5 is not in aligned condition before inserting key, interlock pellet 4 inserts in the groove 3 on main lock core 1 surface by the lockhole of auxiliary lock core 2, and the space that can supply auxiliary lock core 2 to move is arranged in the front portion of auxiliary lock core 2.

Such as Fig. 5, shown in Figure 6, main lock core 1 and auxiliary lock core 2 all are in released state after inserting key 8, and when main lock core 1 rotated, the groove 3 on the main lock core 1 utilized interlock pellets 4 to promote auxiliary lock core 2 and moves along axis; If auxiliary lock core 2 is in not released state then auxiliary lock core 2 can not move along axis in this process, has also just limited main lock core 1 and be rotated further; When main lock core 1 goes back to original position again, promote auxiliary lock cores 2 original position of returning by groove 3 and interlock pellet 4, make the lockhole of main lock core 1, auxiliary lock core 2 and lock body sheath 5 be in aligned condition, at this moment can extract smoothly key 8.

Above-described embodiment, just the patent of the present invention specific embodiment a kind of more preferably is not that patent of the present invention is done any pro forma restriction; Common variation and replacement that those skilled in the art carries out in the technical solution of the present invention scope are equivalent embodiment of the present invention; Simultaneously, the change of overall any equivalent variations that all essence technology according to the present invention are done above embodiment, modify with differentiation etc., all still belong in the scope of technical scheme of the present invention.

Claims

1. novel mechanical lock core, contain main lock core, auxiliary lock core and linkage, it is characterized in that: lock core is comprised of main lock core and auxiliary lock core, linkage is comprised of groove and interlock pellet, at main lock core groove is set, groove is crooked near auxiliary lock core part, when main lock core when the main lock core axis rotates, utilize the bending of groove to move along the main lock core axis by interlock pellet promotion auxiliary lock core.

2. novel mechanical lock core according to claim 1, it is characterized in that: when main lock core rotates, utilize linkage to promote auxiliary lock core and move along the main lock core axis, when auxiliary lock core be in not released state then auxiliary lock core can not move along axis, also just limited main lock core and be rotated further.

3. novel mechanical lock core according to claim 1 is characterized in that: when every group of pellet made main lock core and auxiliary lock core all be in released state simultaneously, main lock core could unrestricted rotation, thereby reaches the purpose of opening lockset.
