Description

Key

The utility model belongs to a kind of key, particularly is exclusively used in a kind of key of core of coding lock.

Chinese patent application CN1062778A discloses a kind of coding built-in lock core and key, Chinese patent application 92214300.5 provides a kind of universal coding lock and key, a kind of handle 1 that perforation is arranged by the center all is provided, one end has external screw thread and is actively socketed on the axis 3 that the other end in the handle 1 has boss 5, be socketed in the handle 1 and with the nut 6 of axis 3 external screw threads engagement, be socketed in the spring 4 on the axis 3 in the handle 1, be enclosed within one group of key code pitch 7 on the outer one section axis 3 of handle 1, the key that the key cover that the one group of external surface that is enclosed within coding pitch 7 external application U-shaped pins serial connection is made of the key code dish of coded markings etc. is formed.This key because between the coding pitch 7, cooperates between coding pitch 7 and the axis 3 not tight, connects looser, the easily rotation or mobile on axis 3 of coding pitch 7, make finish yard easily from line translation, bring inconvenience to the user; When the key of multiple tooth shape inserts lock core, the difficult correctness of accurately judging direction of insertion and position.

The purpose of the utility model is intended to overcome above-mentioned deficiency of the prior art, provides a kind of and encodes between the pitch 7, cooperates key tight, that can accurately locate between coding pitch 7 and the axis 3.

Technical solution of the present utility model is: a kind of key, comprise that there is the handle 1 of perforation at the center, one end has external screw thread and is actively socketed on the axis 3 that the other end in the handle 1 has boss 5, be socketed in the handle 1 and with the nut 6 of axis 3 external screw threads engagement, be socketed in the spring 4 on the axis 3 in the handle 1, be enclosed within one group of key code pitch 7 on handle 1 outer one section axis 3, key cover, its feature part is: go back the caudal lobe blade 9 that movable sleeve is connected to jagged 8 on the axis 3 between spring 4 and the coding pitch 7, an end of caudal lobe blade 9 is fixedly connected on handle 1.

In the utility model technical solution, can have on boss 10, the other end on the end face of coding pitch 7 notch 11 can be arranged, the boss 10 on the adjacent encoder pitch 7 can mesh with notch 11, and the pitch 7 of encoding is in twos closely cooperated mutually.

In the utility model technical solution, in the centre bore of coding pitch 7 equally distributed internal tooth 12 is arranged, there is, quantity corresponding to be equal to or less than internal tooth 12 quantity, axial width external tooth 13 on the axis 3 less than coding pitch 7 centre bore axial widths with internal tooth 12 shapes, the axial distance of 13 of adjacent two external tooths is greater than the axial width of coding pitch 7 centre bores on the axis 3, coding pitch 7 can circumferentially be rotated, so that transfer sign indicating number when breaking away from external tooth 13 on axis 3.

In the utility model technical solution, there is free breach 20 handle 1 outer end, and the retaining briquetting 14 that also can move vertically in vacancy mouth 20 with nut 6 sockets or thread connection is arranged in the vacancy mouth 20.
