The utility model content
For overcoming above-mentioned defective, the purpose of this utility model is: a kind of vane type cylinder lock head is provided, and pellet shot from a slingshot that it is inner and pellet shot from a slingshot hole are easy to process, can effectively reduce the processing cost of tapered end.
The technical measures of taking for achieving the above object: a kind of vane type cylinder lock head, comprise tapered end and be located at the interior lock core of tapered end, on lock core, be provided with some pellet shot from a slingshot holes that communicate with keyhole in the lock core, pellet shot from a slingshot is provided with pellet shot from a slingshot in the hole, pellet shot from a slingshot is provided with slot, is provided with inserted sheet in the outside of slot in the lock core, and described pellet shot from a slingshot is plates, the truncation surface in described pellet shot from a slingshot hole is rectangular, and the width of pellet shot from a slingshot is vertical with the length direction of inserted sheet.
On the outer face of pellet shot from a slingshot, be provided with U-lag.
Described U-lag is positioned at the medium position place of pellet shot from a slingshot width.
Described inserted sheet is " several " font, and the outside in inserted sheet in lock core is provided with roller, and roller is positioned at the medium position place of inserted sheet length direction.
The beneficial effects of the utility model are:
The pellet shot from a slingshot of vane type is plates, and this pellet shot from a slingshot is easy to process, can realize the quick production of pellet shot from a slingshot by the mode of punching press.Match in the rectangular pellet shot from a slingshot hole of the pellet shot from a slingshot of sheet and truncation surface, convex body need be set on pellet shot from a slingshot, pellet shot from a slingshot can not rotate in the pellet shot from a slingshot hole, slot on the pellet shot from a slingshot can be over against inserted sheet, in the pellet shot from a slingshot hole, do not need to be provided with chute yet, can simplify the processing technology of tapered end, save the cost of production of tapered end.

The specific embodiment
The structure of this vane type cylinder lock head comprises tapered end and the lock core of being located in the tapered end 12, is provided with some pellets shot from a slingshot hole on lock core 2, and the pellet shot from a slingshot hole is arranged on the lock core 2 along the axially spaced-apart of lock core 2.Be provided with keyhole 4 in lock core 2, all pellet shot from a slingshot holes all communicate with keyhole 4.Be used to place pellet shot from a slingshot 3 in the pellet shot from a slingshot hole, after pellet shot from a slingshot 3 was placed in the pellet shot from a slingshot hole, the inner end of pellet shot from a slingshot 3 extend in the keyhole 4.After in key 9 is inserted into keyhole 4, key 9 promotes the outer end motion of pellet shot from a slingshot 3 towards pellet shot from a slingshot 3.The side of pellet shot from a slingshot 3 is provided with slot 5, and the position and the differential of key 9 of the slot 5 on all pellets shot from a slingshot 3 adapt.Be provided with inserted sheet 7 in the outside of slot 5 in the lock core 2, inserted sheet 7 can radially slide along lock core 2.After in key 9 is inserted into keyhole 4, under the promotion of key 9, the slot 5 on all pellets shot from a slingshot 3 all is positioned at the position of inserted sheet 7, for the inner side edge insertion of inserted sheet 7.
Pellet shot from a slingshot 3 is plates, and the truncation surface in pellet shot from a slingshot hole is rectangular, and the width of pellet shot from a slingshot 3 is vertical with the length direction of inserted sheet 7.The outer face of pellet shot from a slingshot 3 is provided with U-lag 11, and this U-lag 11 is positioned at the medium position place of pellet shot from a slingshot 3 widths.Be provided with marble spring 8 in the outside of pellet shot from a slingshot 3 in the pellet shot from a slingshot hole, the inner end of marble spring 8 contacts with the bottom surface of described U-lag 11, and marble spring 8 is good with the outer face contact stabilization of pellet shot from a slingshot 3.
The lateral surface of inserted sheet 7 can be made into arc, also can be in the columniform roller 6 of the arranged outside of inserted sheet 7 in lock core 2.When being provided with columniform roller 6, inserted sheet 7 is by system " several " fonts, this convenient processing, the good operating stability of tapered end.Be provided with the inserted sheet spring in lock core 2, the both ends of inserted sheet spring act on respectively on lock core 2 and the inserted sheet 7, and under the effect of inserted sheet spring, inserted sheet 7 has the trend to lock core 2 movement outside.Be provided with draw-in groove 10 on the fitting face of tapered end 1 and lock core 2, draw-in groove 10 is parallel with roller 6, and roller 6 can be connected in the draw-in groove 10, rotates with respect to tapered end 1 with restriction lock core 2.
When utilizing key 9 to open tapered end, key 9 makes the slot 5 on the pellet shot from a slingshot 3 all be positioned at the position of inserted sheet 7, when pulling key 9, draw-in groove 10 in the tapered end 1 gives roller 6 and applies shearing force, roller 6 compressing inserted sheets 7, inserted sheet 7 is inserted in the slot 5 on the pellet shot from a slingshot 3, and lock core 2 can freely rotate in tapered end 1 under the drive of key 9.After extracting key 9, under the effect of marble spring 8, the inner end of pellet shot from a slingshot 3 extend in the keyhole 4, and the slot 5 on the pellet shot from a slingshot 3 is displaced to outside the position of inserted sheet 7, the space of not inserting for inserted sheet 7 inner side edges on the pellet shot from a slingshot 3, roller 6 can be connected in the draw-in groove 10 securely.
