The utility model content
In order to overcome the defective of above-mentioned prior art, the utility model provides a kind of anti-interior breech lock of three row's pellets that the good and anti-brute force of performance is turned on of dialling.
The utility model is realized by following scheme: breech lock in a kind of three row's pellets, comprise key, lock core, spring, the flat pellet of grooving, door bolt channel-section steel pearl, interior door bolt, lock housing, middle lower pellet, pellet on the centre, middle springs and sealing steel ball, described spring, the flat pellet of grooving, door bolt channel-section steel pearl, interior door bolt, middle lower pellet, pellet on the centre, middle springs and sealing steel ball all are assembled in the lock core, described lock core is inserted in the lock housing, have in the described lock core 〉=9 double-row marble holes, be equipped with in the hole 〉=9 flat pellets of grooving and 〉=9 springs, the flat pellet of described grooving has the different limit groove of height, the described different tooth hole of the depth of being processed on the key, after the key of checking the number inserts lock core, the flat pellet of all groovings is pushed down into key tooth hole at the active force of spring, and at this moment the flat bullet groove all align of grooving is arranged on the line corresponding with interior door bolt.Described interior door bolt one side has groove, is provided with door bolt channel-section steel pearl in the groove, as rotating key band movable lock core, in be latched under the effect of V-type groove of channel-section steel pearl and lock housing, enter in the grooving of flat pellet.
The utility model has increased again by a row in the centre of the flat pellet of both sides grooving, formed by pellet, middle springs and sealing steel ball on pellet, the centre under the centre, formed breech lock in three row's pellets, also to upper key number (such as Fig. 2 and Fig. 3), lock is just easily opened as at this moment.Such as the key unreserved seating, then the flat pellet of grooving under the effect of spring force, interior door bolt can not enter in the grooving of flat pellet, so interior door bolt and the locking in the V-type groove of lock housing of door bolt channel-section steel pearl have added upper and lower five pellets key at this moment in the middle of adding and more may open this lockset.
The utlity model has following beneficial effect:
1, the utility model has increased again by a row in the centre of the flat pellet of both sides grooving and has formed breech lock in three row's pellets, can make tooth hole permutation and combination number reach the possibility of having avoided lockset to open mutually more than one hundred million times.
2, when the key unreserved seating, described, anti-brute force is turned on to the full extent.
But 3, the utility model extensive use and various antitheft occasion.
Description of drawings
Fig. 1 is structure explosive view of the present utility model;
Fig. 2 is that the utility model is opened the lockset schematic diagram after to upper key number;
Fig. 3 is interior door bolt of the present utility model and door bolt channel-section steel pearl locking schematic diagram in the V-type groove of lock housing.
Wherein, pellet, 10-middle springs, 11-seal steel ball on 1-key, 2-lock core, 3-spring, the flat pellet of 4-grooving, 5-door bolt channel-section steel pearl, the interior door bolt of 6-, 7-lock housing, the middle lower pellet of 8-, the 9-centre
The specific embodiment
Such as Fig. 1, shown in Figure 2: breech lock in a kind of three row's pellets, comprise key 1, lock core 2, spring 3, the flat pellet 4 of grooving, door bolt channel-section steel pearl 5, interior door bolt 6, lock housing 7, middle lower pellet 8, pellet 9 on the centre, middle springs 10 and sealing steel ball 11, described spring 3, the flat pellet 4 of grooving, door bolt channel-section steel pearl 5, interior door bolt 6, middle lower pellet 8, pellet 9 on the centre, middle springs 10 and sealing steel ball 11 all are assembled in the lock core 2, described lock core 2 is inserted in the lock housing 7, have in the described lock core 2 〉=9 double-row marble holes, be equipped with in the hole 〉=9 flat pellets 4 of grooving and 〉=9 springs 3, the flat pellet 4 of described grooving has the different limit groove of height, be processed into the different tooth hole of the depth on the described key 1, after the key 1 of checking the number inserts lock core 2, the flat pellet 4 of all groovings is pushed down into key 1 tooth hole at the active force of spring 3, and at this moment the flat pellet 4 groove all aligns of grooving are arranged on the line corresponding with interior door bolt 6.Described interior door bolt 6 one sides have groove, are provided with door bolt channel-section steel pearl 5 in the groove, and as rotating key 1 band movable lock core 2, interior door bolt 6 enters in the grooving of flat pellet under the effect of the V-type groove of door bolt channel-section steel pearl 5 and lock housing 7.
