Description
Technical field
The utility model relates to a kind of lock core.
Background technology
Along with modern science and technology constantly progress, enterprise improves the improvement of production efficiency higher requirement, and in existing blade lock core, and in blade cover, the needle roller groove of blade used is only one and asymmetric with fan-shaped outstanding afterbody, during use, blade must be installed in front in the same way, and installation efficiency is lower.
Utility model content
In view of this, technical problem to be solved in the utility model is: provide a kind of leave dual sides all can be installed in blade cover and be suitable for Automated assembly, lock core that installation efficiency is high thus.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of lock core, comprise and there is blade cover, the plug body of needle roller and blade, the side of described blade cover has the vane groove of multi-layer drawer, in each described vane groove, described blade is all housed, the outer wall of described blade cover has needle roller caulking groove, the outer rim of described blade has needle roller groove and has keyhole in middle part, described needle roller contact is in described needle roller caulking groove, wherein, described needle roller caulking groove is opened on the outside cell wall of described vane groove, described needle roller groove comprises the first needle roller groove and the second needle roller groove, described first needle roller groove and the second needle roller groove are in symmetrical position, described blade center both sides, the bottom of described blade cover is inwardly convexly equipped with when blade rotary to described needle roller is pressed into described needle roller groove for the block dialling gear through the key bottom that described keyhole inserts.
As preferably, described block is be located at two on described blade cover bilateral symmetry position, center.
As preferably, described blade cover overlaps or plastic sheath for non-ferrous metal, and described blade is non-ferrous metal sheet.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, blade in the utility model cover is full-closed structure, and intensity is large, more firmly, and leave dual sides all can be installed in blade cover and be suitable for Automated assembly thus, installation efficiency is high.Specifically, needle roller caulking groove and needle roller groove are in the same side, needle roller is put into again after blade first can being loaded blade cover, blade and needle roller is avoided to drop out because putting two sides, meanwhile, after the block control key turns angle of blade cover bottom, blade does not have afterbody, the needle roller groove bilateral symmetry of blade is arranged, and can reduce the cost of blade, realize comprehensive any loading.

Detailed description of the invention
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing.
Refer to shown in Fig. 1 to Fig. 4, the utility model provides a kind of lock core, comprise and there is blade cover 1, the plug body of needle roller (not shown) and blade 2, the side of described blade cover has the vane groove 3 of multi-layer drawer, in each described vane groove, described blade is all housed, the outer wall of described blade cover has needle roller caulking groove 4, the outer rim of described blade has needle roller groove and has keyhole 5 in middle part, described needle roller contact is in described needle roller caulking groove, wherein, described needle roller caulking groove is opened on the outside cell wall 6 of described vane groove, described needle roller groove comprises the first needle roller groove 7 and the second needle roller groove 8, described first needle roller groove and the second needle roller groove are in symmetrical position, described blade center both sides, the bottom of described blade cover is inwardly convexly equipped with when blade rotary to described needle roller is pressed into described needle roller groove for the block 9 dialling gear through the key bottom that described keyhole inserts, described block is be located at two on described blade cover bilateral symmetry position, center, described blade cover is non-ferrous metal cover or plastic sheath, described blade is non-ferrous metal sheet.In the utility model, the needle roller groove of described blade can change according to the angle of key tooth flower, but all symmetrical in keyhole both sides.
The operating principle applying lock of the present utility model is: blade loads arbitrarily in the vane groove of the multi-layer drawer blade cover, during use, key is passed in single file by the keyhole of blade, be inserted to the bottom of blade cover, when key turns goes to block, key stops operating, now, the needle roller caulking groove that needle roller groove alignment blade on blade puts, now, needle roller heads in needle roller groove, then, key be rotated further stir block band moving vane cover and blade integral rotation thus realize unlock operation.
But the foregoing is only better possible embodiments of the present utility model, and be not used to limit to the scope of the claims of the present utility model, therefore the equivalent structure change that all utilization the utility model manuals and accompanying drawing content are done, be all in like manner included in scope of the present utility model.
