Description

The anti-theft lock that has big pellet shot from a slingshot

Technical field:

The utility model relates to a kind of lock core, particularly a kind of anti-theft lock that has big pellet shot from a slingshot.

Background technology:

Current, anti-theft lock is a lot of on the market, have the people to design a kind of anti-theft lock that has protective sheet and locking groove in order to improve theftproof performance, the patent No. is: though 200320113865.6 this lock cores on theftproof performance, increase,, also exist deficiency, if adopt first push-tight with respect to the pellet shot from a slingshot on the protective sheet, and then the method for loosening, lock core still can be unlocked, so theftproof performance is poor.

Summary of the invention:

In order to address the above problem, the utility model provides a kind of anti-theft lock that has big pellet shot from a slingshot, is made up of outer core and inner core, is provided with big pellet shot from a slingshot, telescopic half pellet shot from a slingshot in the lock core.The circular arc loose slot is arranged on lock core, half cylinder type spring detent and domatic spring detent are arranged on the core outside.When not opening, the front end of telescopic half pellet shot from a slingshot extends ultimate attainment, the front end of half cylinder type spring detent and domatic spring detent withstands on the outer wall of inner core, only when opening, go to open with the key that is complementary, just can make the upper end of telescopic half pellet shot from a slingshot concordant with the inner rotary face of inner core, the utility model can seal keyhole by the device of big pellet shot from a slingshot sealed key hole, make foreign matter be difficult to be deep in the keyhole that is closed, touching is less than telescopic half pellet shot from a slingshot; Reached antitheft effect.

The technical solution of the utility model is:

The anti-theft lock that has big pellet shot from a slingshot is made up of outer core 1, inner core 2, in the big pellet shot from a slingshot hole 12 that two row's direction relative positions stagger big pellet shot from a slingshot 13 is installed, and through outer core 1, inner core 2, the front end of big pellet shot from a slingshot passes keyhole, and withstands on the wall on opposite.And the thickness of big pellet shot from a slingshot is 1/2 or 2/3 of keyhole thickness.Common spring 10 is installed in the common spring hole 4, through outer core 1, inner core 2, in the telescopic half pellet shot from a slingshot hole 5 telescopic half pellet shot from a slingshot 11 is installed, run through inner core 2, projection 14 is arranged at the bottom of telescopic half pellet shot from a slingshot 11, on the top of projection 14, the outside of telescopic half pellet shot from a slingshot is provided with spring 15, and the elastic force of the spring of half cylinder type spring detent rear end is greater than the elastic force of the spring of telescopic half pellet shot from a slingshot 11 outsides.On the inwall of core, circular arc loose slot 6 is arranged on the position with respect to telescopic half pellet shot from a slingshot outside, and the arc length of circular arc loose slot 6 is greater than the diameter of telescopic half pellet shot from a slingshot 11; In the circular arc loose slot 6 of core domatic spring detent 16 is arranged outside; Half cylinder type spring detent 9 is arranged on the core outside.When opening not, stagger in the position of telescopic half pellet shot from a slingshot 11 and half cylinder type spring detent 9.

Operating principle of the present utility model:

When non-opening, the front end of common spring reaches in the keyhole, and the front end of big pellet shot from a slingshot passes keyhole, and withstands on the wall on opposite.Telescopic half pellet shot from a slingshot is owing to the effect of spring, and it is ultimate attainment that telescopic half pellet shot from a slingshot is extended, and the half cylinder type spring detent in the outer core and the front end of domatic spring detent withstand on the outer wall of inner core.

When normal unlatching, key inserts in the keyhole, the front end of common spring matches with teeth groove on the key, the front end of big pellet shot from a slingshot matches with teeth groove on the key, the front end of telescopic half pellet shot from a slingshot matches with teeth groove on the key, the section that makes each pellet shot from a slingshot matches with the rotation interface of outer core and SMIS, key at this moment, and lock core is normally opened.

The beneficial effects of the utility model:

Owing in lock core, be provided with the technology of the device and telescopic half pellet shot from a slingshot of big pellet shot from a slingshot sealed key hole, make foreign matter be difficult to extend in the keyhole of sealing, touching is difficult to lock core is opened less than telescopic half pellet shot from a slingshot that stretches out, and has reached antitheft effect.

The specific embodiment:

As Fig. 1---have the anti-theft lock of big pellet shot from a slingshot shown in 5, form by outer core 1, inner core 2, in the big pellet shot from a slingshot hole 12 that two row's direction relative positions stagger big pellet shot from a slingshot 13 is installed, through outer core 1, inner core 2, the front end of big pellet shot from a slingshot passes keyhole, and withstands on the wall on opposite.And the thickness of big pellet shot from a slingshot is 1/2 or 2/3 of keyhole thickness.Common spring 10 is installed in the common spring hole 4, through outer core 1, inner core 2, in the telescopic half pellet shot from a slingshot hole 5 telescopic half pellet shot from a slingshot 11 is installed, run through inner core 2, projection 14 is arranged at the bottom of telescopic half pellet shot from a slingshot 11, on the top of projection 14, the outside of telescopic half pellet shot from a slingshot is provided with spring 15, and the elastic force of the spring of half cylinder type spring detent rear end is greater than the elastic force of the spring of telescopic half pellet shot from a slingshot 11 outsides.On the inwall of core, circular arc loose slot 6 is arranged on the position with respect to telescopic half pellet shot from a slingshot outside, and the arc length of circular arc loose slot 6 is greater than the diameter of telescopic half pellet shot from a slingshot 11; In the circular arc loose slot 6 of core domatic spring detent 16 is arranged outside; Half cylinder type spring detent 9 is arranged on the core outside.When opening not, stagger in the position of telescopic half pellet shot from a slingshot 11 and half cylinder type spring detent 9.

When unnormal unlocking: remove unnormal unlocking with foreign matter, when if the upper end of telescopic half pellet shot from a slingshot is lower than the outer commentaries on classics face of inner core, when go to outside during the relative position of first cylinder type spring detent of core, the front end of half cylinder type spring detent can be deep in the telescopic half pellet shot from a slingshot hole, makes the inner core limited in rotation.Owing to utilize big pellet shot from a slingshot to seal the technology of keyhole, do not have the telescopic half pellet shot from a slingshot application of force of foreign matter to stretching out, the strength of the spring of half cylinder type spring detent rear end can be pushed into the limit to telescopic half pellet shot from a slingshot, and lock core is stuck, promptly can not can not be rotated further again with changeing.

And for example the upper end of telescopic half pellet shot from a slingshot of fruit is higher than the outer commentaries on classics face of inner core, when go to outside on the core during position of domatic spring detent, because domatic spring detent is domatic towards the one side of telescopic half pellet shot from a slingshot, so the outside core direction motion of domatic spring detent can be oppressed in the upper end of telescopic half pellet shot from a slingshot, and by domatic spring detent, on the inwall that touches circular arc loose slot one side, promptly can not be rotated further, can not turn round again, make the inner core limited in rotation.Simultaneously, the big pellet shot from a slingshot of utilization has sealed keyhole, and foreign matter can't be extend in the keyhole, so improper means can not be opened lock core.
