Abstract

The utility model discloses an unlocking controller for a cylinder spring lock, comprising a cylinder body, an inner cylinder, an outer cylinder and a spring. The key hole width of the unlocking controller is smaller than the half of the diameter of the cylinder body, the compression length of the spring is smaller than the length sum of the inner and the outer cylinders which are arranged in a cylinder hole. The unlocking controller of the cylinder spring lock has reasonable and safe structure, and can not be opened by a non-special key.

Description

Unlocking controller for spring lock

The utility model relates to a kind of safety of ball spring lock and starts control device, includes: Cylinder, the outer pellet shot from a slingshot of interior pellet shot from a slingshot and spring.

At present, the ball spring lock of selling on the market start control device, the keyhole width is big, account for 3/4 of Cylinder diameter, pellet shot from a slingshot is positioned at the reduction length of the length in pellet shot from a slingshot hole less than spring, as long as master key or other picklock are inserted in the keyhole, the end face that pellet shot from a slingshot is positioned at keyhole extrudes pellet shot from a slingshot hole collar extension, and lock just can easy being opened.Current, along with the appearance of master key, the lock of this structure will lose its safety effect.

The purpose of this utility model is to provide the control device that starts of the high ball spring lock of a kind of security reliability, and the lock of this device is except that private key, and other non-private key all can not be opened it.

The purpose of this utility model can realize by following measures: the utility model includes: Cylinder, interior pellet shot from a slingshot, outer pellet shot from a slingshot and spring; Along axis direction a keyhole is arranged in Cylinder, this keyhole is used for inserting key, and its width is not more than 1/2 of Cylinder diameter; Keyhole collar extension width is equal to or slightly less than the Cylinder diameter, and this width is in order to adapt to the needs of key root width; Because the key width is less, be convenient processing, the section configuration of key make "

" shape, its corresponding keyhole section configuration also be "

" shape; In Cylinder, pellet shot from a slingshot hole with the Cylinder intersect vertical axis is arranged, inside and outside pellet shot from a slingshot is the garden cylindricality, the total length of interior pellet shot from a slingshot is positioned at the pellet shot from a slingshot hole with the partial-length of outer pellet shot from a slingshot, their heterodoxy end face contacts, and the end face of the interior pellet shot from a slingshot other end is a convex surface, is positioned at keyhole or pellet shot from a slingshot hole, the outer face of outer pellet shot from a slingshot contacts with spring, and inside and outside pellet shot from a slingshot is used for controlling Cylinder and rotates; In Cylinder the inner, have only an outer pellet shot from a slingshot, its partial-length is arranged in bullet groove, and pellet shot from a slingshot is the axial restraint that is used for Cylinder in this; Spring and inside and outside pellet shot from a slingshot are positioned on same the axis, and contact with the outer end end face of outer pellet shot from a slingshot, and spring is that pellet shot from a slingshot and key are contacted in being used for guaranteeing; Inside and outside pellet shot from a slingshot is positioned at the reduction length of the length sum of keyhole greater than spring, and just the reduction length of spring is positioned at the length sum in pellet shot from a slingshot hole less than inside and outside pellet shot from a slingshot.Structure of the present utility model has guaranteed that other non-private key all can not insert in the keyhole, and the end face that interior pellet shot from a slingshot is positioned at keyhole one end extrudes pellet shot from a slingshot hole collar extension, and lock is opened.

The utility model is rational in infrastructure, and is safe and reliable, is that the ideal of the non-private key of a kind of usefulness ball spring lock of not opening is started control device.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is the front view that starts control device of ball spring lock.

Fig. 2 is the vertical view that starts control device of ball spring lock

Fig. 3 is the right view that starts control device of ball spring lock

By Fig. 1,2,3 as can be known, present embodiment comprises: Cylinder (1), interior pellet shot from a slingshot (5), outer pellet shot from a slingshot (6) and spring (7); Along axis direction a keyhole (2) is arranged in Cylinder (1), this hole is used for inserting key, and its width is not more than 1/2 of Cylinder (1) diameter; The width of keyhole collar extension (3) equals the diameter of Cylinder (1), and this width is in order to adapt to the needs of key root width; Because the key width is less, be convenient processing, the section configuration of key make "

" shape, the section configuration of its corresponding keyhole (2) be "

" shape; In Cylinder (1), pellet shot from a slingshot hole (4) with its intersect vertical axis is arranged, interior pellet shot from a slingshot (5) is the garden cylindricality with outer pellet shot from a slingshot (6), the total length of interior pellet shot from a slingshot (5) is positioned at pellet shot from a slingshot hole (4) with the partial-length of outer pellet shot from a slingshot (6), their two heterodoxy end faces contact, the end face of interior pellet shot from a slingshot (5) other end is a convex surface, be positioned at keyhole (2) or pellet shot from a slingshot hole (4), the outer face of outer pellet shot from a slingshot (6) contacts with spring (7), and interior pellet shot from a slingshot (5) is used for controlling Cylinder (1) with outer pellet shot from a slingshot (6) and rotates; In Cylinder (1) the inner, have only an outer pellet shot from a slingshot (6), its partial-length is positioned at bullet groove (8), is used for Cylinder (1) axial restraint; Spring (7) is positioned on same the axis with interior pellet shot from a slingshot (5) and outer pellet shot from a slingshot (6), and contacts with the outer face of outer pellet shot from a slingshot (6), and spring (7) is to be used for guaranteeing that interior pellet shot from a slingshot (5) and key are contacted; Interior pellet shot from a slingshot (5) is positioned at the reduction length of the length sum in pellet shot from a slingshot hole (4) greater than spring (7) with outer pellet shot from a slingshot (6), and just the reduction length of spring (7) is positioned at the length sum in pellet shot from a slingshot hole (4) less than interior pellet shot from a slingshot (5) and outer pellet shot from a slingshot (6).The structure that present embodiment adopts has guaranteed that other non-private key all can not insert in the keyhole (2), and the end face that interior pellet shot from a slingshot (5) is positioned at keyhole (2) one ends extrudes pellet shot from a slingshot hole (4) collar extension, and lock is opened.Present embodiment all selects for use metal material to be made.
