Abstract
The utility model relates to a spring ball group of spring lock, particularly a spring ball group which only generates small frictional resistance when spring balls move along a spring ball tunnel. The first spring ball of the spring ball group is made into a rotor which can roll along the spring ball tunnel. When a key inserted into a keyhole contacts the first spring ball, the first spring ball can flexibly roll and let by.
Description
The utility model relates to a kind of bullet group of cylinder lock.
At present, the profile of each bullet is cylindric basically in the bullet group of cylinder lock.And the axial line in the axial line of cylinder and bullet duct coincides.Bullet can only slide along the bullet duct during work.In order to reduce slip resistance, have on key and keyhole, adopt certain specific structure.For example: the thickness of key bit and the width of keyhole all are less than the diameter of cylinder-shaped bullet.Its result has limited the diversified development of key and lockset.
The utility model provides a kind of and only produces the bullet group of less frictional resistance when bullet when move in the bullet duct.Its solution is: the profile of a ball of bullet group is made a rotary body that can roll along the bullet duct.Like this, when key inserted keyhole and contacts to the end ball, a ball just can roll delicately and dodge.
The utility model has replaced a ball that slides with a ball that rolls, and makes key and keyhole break away from the restriction of the sort of ad hoc structure.For the abundant of key and lockset and development provide a new direction.Be 87204970.1 utility model patent particularly, immeasurable meaning is arranged implementing the patent No..
The best embodiment of the utility model has two kinds.A kind of is that the rotary body profile of a ball is made an axis of rotation both perpendicular to the bullet duct, again perpendicular to the pie trundle of key direction of insertion, can reduce the volume of bullet group and lockset like this.Another kind is that the rotary body profile of a ball is made a ball, can simplify the manufacturing process in bullet duct like this.
Accompanying drawing has been described an embodiment of the present utility model.Fig. 1 is the front view after dissecing along the key direction of insertion; Fig. 2 is the left view of Fig. 1.
The bullet group is by a ball (6) and middle ball (4) and tail ball (3) formation.The lower end in stairstepping bullet duct (5) is made into the cavity that one enough ball (6) rolls.When key (8) inserts keyhole (7) and a ball (6) when contacting, a ball (6) scrolls up delicately under the effect of contact force and dodges.Ball (4) and tail ball (3) in promoting simultaneously, compression spring (2).Stopper that is fixed with one with lock body in said process (1) and spring (2) synergy, a compressing ball (6) contacts with key (8) all the time.
Claims (3)
1, a kind of bullet group of used for spring lock, by the ball (6) of contact key with adjust the middle ball (4) of bullet group length and the tail ball (3) of contact spring (2) is formed, it is characterized in that: described ball (6) be one can be along the rotary body of bullet duct (5) rolling.
2, bullet group according to claim 1 is characterized in that: described rotary body is that an axis of rotation is not only perpendicular to the bullet duct but also perpendicular to the pie trundle of key direction of insertion.
3, bullet group according to claim 1 is characterized in that: described rotary body is a ball.
