Abstract
The utility model discloses a lock core with a spiral trough, comprising a marble hole and a spiral trough. The spiral trough is circled between the marble holes; the spiral trough is in ladder shape. The utility model can quicken the processing speed of the spiral trough on the lock core, reduces the damage of machining tools, reduces cost, and is convenient for the assembly of the lock core.
Description
Affiliated technical field
The utility model relates to a kind of lockset with stairstepping helicla flute lock core.
Background technology
At present, the lock core of the helical groove structure of employing, employing be conventional spiral-shaped, spiral between the pellet shot from a slingshot hole.Owing to be subjected to the restriction of distance between the adjacent pellet shot from a slingshot hole, the spiral fluted width is very narrow, make the processing lock core very inconvenient, the feed cutting speed that adds man-hour must be controlled slower speed, otherwise cutter fractures easily, production capacity is carried not high, and cost is also high, and is also like this corresponding to the helicla flute on the lock body.
Summary of the invention
For the spiral fluted width that overcomes existing lock core is very narrow, make processing difficulties, inefficient shortcoming, the utility model provides a kind of stairstepping spiral fluted lock core that has, it can accelerate spiral fluted process velocity on the lock core, reduces the damage of machining tool, reduces cost.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of have a spiral fluted lock core, includes pellet shot from a slingshot hole and helicla flute, and described helicla flute spirals between the pellet shot from a slingshot hole, and described helicla flute is a stairstepping.
The beneficial effects of the utility model are, because helicla flute of the present utility model has adopted the stairstepping helical groove structure, make the width of the groove between the pellet shot from a slingshot hole become big relatively, be convenient to processing, requirement to the machining instrument also reduces, reduce cost, improved job schedule, also made things convenient for the assembling of lock core simultaneously.
Description of drawings
Fig. 1 is a schematic side view of the present utility model.
1. lock cores among the figure, 2. pellet shot from a slingshot hole, 3. helicla flute
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Existing helicla flute is the parallel oblique line between the pellet shot from a slingshot hole in lateral view, is subjected to the restriction of distance between adjacent two pellet shot from a slingshot holes again, makes the spiral fluted width to strengthen, and has increased difficulty of processing.Lock body in the lockset has the structure corresponding with lock core, flexibly connects with lock core.
We can see a kind of spiral fluted lock core that has from Fig. 1, include pellet shot from a slingshot hole 2 and helicla flute 3, and described helicla flute 3 spirals between pellet shot from a slingshot hole 2, and described helicla flute 3 is a stairstepping.Lock body in the lockset has the structure corresponding with lock core, flexibly connects with lock core.
Helicla flute of the present utility model part between the pellet shot from a slingshot hole in lateral view is parallel straight line, thereby can increase the spiral fluted width, has reduced difficulty of processing.
For the ease of operation, the smooth connection of stairstepping helicla flute each several part.
The utility model is work like this: when key drove the lock core rotation, because the spiral fluted structure, the relative lock body of lock core moved axially.
Claims (2)
1. one kind has the spiral fluted lock core, includes pellet shot from a slingshot hole (2) and helicla flute (3), and described helicla flute (3) spirals between pellet shot from a slingshot hole (2), it is characterized in that described helicla flute (3) is a stairstepping.
2. according to claim 1 have a spiral fluted lock core, it is characterized in that the smooth connection of described stairstepping helicla flute (3) each several part.
