Abstract

The invention discloses a multi-cylinder lock bit, which is characterized in that the inside of a lock bit is provided with a plurality of lock cylinders and a plurality of sets of locking mechanisms; as an example shown in a Figure 4, the lock cylinders (including an outer lock cylinder 3, an upper lock cylinder 4 and a lower lock cylinder 5) of a three-cylinder lock bit are framed and represented by dotted lines; the structure layout drawings of the three-sets of locking mechanisms respectively consisting of the lock cylinders above are as follows: a locking mechanism for the outer lock cylinder is shown in a Figure 9, a locking mechanism for the upper lock cylinder is shown in a Figure 10, and a locking mechanism for the lower lock cylinder is shown in a Figure 11; and a set of lock cylinder (namely, a middle lock cylinder 6 shown in a Figure 5) is added between the upper lock cylinder 4 and the lower lock cylinder 5, then a four-cylinder lock bit is formed. Through carrying out 45-degree staggered arrangement on the key-tooth accommodating grooves of the upper and lower lock cylinders, a state that the locking mechanism of the lower lock cylinder 5 is completely shielded by a metal lock cylinder body of the upper lock cylinder 4 is formed, thereby truly achieving the cylinder-shielding effect of locksets. Compared with common lock bits, the capability of a cylinder-shielded and multi-cylinder lock bit in violent opening and technique countermeasures is incomparable.

Description

The manufacture method of multicore tapered end

Technical field

The present invention relates to lockset, be specifically related to tapered end, a tapered end that constitutes by a plurality of lock cores.

Background technology

Make a general survey of all mechanical billiard type locksets, locking mechanisms of forming by single lock core all, its structure is too simple and with low content of technology, some problems and the defective that are exposed, all embody a concentrated reflection of in the shortcoming of resisting technical antagonism and anti-violence unlatching ability, thereby theft case happens occasionally.

Summary of the invention

The present invention---multicore tapered end is to be provided with a plurality of lock cores and many group locking mechanisms in a tapered end, example as shown in Figure 4, and each lock core of three core tapered ends is confined expression by dotted line: outer lock core 3, upper lock core 4 and following lock core 5; Its form of structure is: outer lock core 3 is made of the core body 1-1 that locks, lock core body overcoat 2 and outer lock core locking pellet shot from a slingshot 10; Upper lock core 4 is made of the core body 1-1 that locks, lock core body overcoat 2, outer lock core locking pellet shot from a slingshot 10 and upper lock core locking pellet shot from a slingshot 11; Following lock core 5 is made of down lock core body 1-2, lock core body overcoat 2 and following lock core locking pellet shot from a slingshot 12, illustrates with the topology layout of three groups of locking mechanisms of its formation: outer lock core locking mechanism as shown in Figure 9, upper lock core locking mechanism shown in Figure 10 and following lock core locking mechanism shown in Figure 11; Between upper lock core 4 and following lock core 5, install one group of lock core again additional, middle lock core 6 as shown in Figure 5 promptly constitutes the four-core tapered end.

Feature:

1, in a tapered end, is provided with a plurality of lock cores and organize locking mechanism more;

2, upper and lower lock is the setting of 45 ° of key bit core tank dislocation;

Characteristic:

1, has the ability that opposes violence and open: for example a kind of cross or yi word pattern steel latch of robber's special use and have the instrument of boosting-rod, insert in the lock core key bit tank hole, reinforcing effect by lever prizes, locking mechanism is destroyed and be unlocked, feature 1 of the present invention is, in a tapered end, be provided with a plurality of lock cores and many group locking mechanisms, even the instrument that the robber adopts violence to open, also can only destroy first road or the second road locking mechanism at most, the 3rd road mechanism is still locking lockset.

2, the ability that possesses technical antagonism:

(1) described characteristic 2, the setting that the key bit tank dislocation of

upper lock core

4 and 5 liang of lock cores of following lock core is 45 °, the superimposed following lock core 5 that is constituted in the lock housing body that is installed in, shielded the tool state fully by the metallic object of upper lock core 4, door just as one iron and steel, worker's (device) tool that stops all improper uses to be opened, comprise and touch entering of son (master key), steel wire etc., it can only be 1/2 degree of depth of inserting tapered end at most that violence enters, and is that the spy that can't enter other lock core that is shielded by upper lock core 4 again reaches and gropes;

(2) the three core tapered ends that exemplify of the present invention, each self-locking function of three groups of locking mechanisms that possessed, carry out technical unlocking even suffer from top lockset technical ability master-hand to the multicore tapered end, because the mutual restriction lock of many group locking mechanisms is programs, he can not operate three instruments or implements simultaneously with two hands, implements the operational motion of opening.

(3) the size of key index is high: the locking of outer lock core locking mechanism and deciphering (unlatching), and just like the parameter of " magic square " formula: it can be with a locking pellet shot from a slingshot, also can be to be spaced with several locking pellets shot from a slingshot; Can be to be pellet shot from a slingshot with one group of lock, also can be with array locking pellet shot from a slingshot locking outer lock core; Or it is fixed to give twin-lock with the interlock of the locking mechanism of outer lock core 3 and upper lock core 4; As shown in Figure 5 between upper lock core 4 and following lock core 5, add again one group the locking pellet shot from a slingshot 6, promptly constitute four lock core tapered ends; The deciphering of locking mechanism and key (unlatching), the setting scheme can necessarily change, and complicated setting scheme difficulty is bigger, it similarly is a kind of maths game, at first want example to go out calculation equation, lock the calculation that pellet shot from a slingshot is arranged, just can lock the setting that pellet shot from a slingshot is arranged then.

Technical scheme (simple and clear example)

(making) method of producing of three core tapered end lock cores is a core content of the present invention, the simplest and the clearest and the most vivid elaboration method is: as shown in Figure 2, the lock core of the yi word pattern tapered end of the cross or bilateral tooth of the modern market sale of enchashment, cut from cutting line 2 divisions, promptly obtain two members of upper lock core 4 and following lock core 5; To descend lock core 5 its key bit tanks parallel and be installed in the lock housing body perpendicular to horizon, key bit tank orientation of living in as shown in Figure 6; Take the setting scheme that shifts to install:, promptly constitute upper lock core 4 key bit tanks and 45 ° of dislocation of following lock core 5 key bit tanks, as shown in Figure 7 with upper lock core 4 and following lock core 5 superimposed being installed in the lock housing body; 45 ° of settings of key bit tank dislocation of upper lock core 4 and following lock core 5, the superimposed superimposed form that is installed in lock core 5 key bit tanks under the metallic object shielding that constitutes upper lock core 4 in the lock housing body, as shown in Figure 8, but See among the figure: the metallic object of upper lock core 4 has shielded time lock core 5 key bit tanks fully, has played latent core effect and has stoped other key or worker's (device) tool illegal (unnormal unlocking) to be insinuated into down lock core 5; Use original-pack key normally to open, when the key insertion depth reaches 1/2, the metallic object that the spoon head touches the following lock core 5 of conductively-closed stops, this just shows that key bit has arrived the desired location of opening outer lock core 3, first program that can implement to unblank: by turn clockwise 45 ° (or 135 ° or 225 °) of setting, this spinning movement has been opened the locking mechanism of outer lock core 3 for opening the breakdown action of outer lock core 3; This anglec of rotation is ' error correction ' angle, corrected because of the metal latch core body of the formed upper lock core 4 of the design scheme that shifts to install to the shielding of lock core 5 key bit tanks down, thereby lock core 5 is removed by the shielding of upper lock core 4, it is all vertical and be parallel to horizontal uniformity to reach the key bit tank orientation of living in of 5 two lock cores of upper lock core 4 and following lock core, key could be inserted into down lock core 5 by designing requirement, realizes the unlatching to this tapered end.As shown in Figure 4 upper lock core 4 and following lock core 5, they must reach upper lock core and shift to install angle spacing hole 7 respectively at upper lock core location tank 13 and following lock core location tank 14 that the cylindrical cylindrical of lock core shapes; The lock core number of multicore tapered end is can set it arbitrarily to increase or subtract, and lock core 6 promptly constitutes the four-core tapered end in the setting up between upper lock core 4 and following lock core 5 as shown in Figure 5.
