Embodiment

In the utility model, except as otherwise clear stipulaties and restriction, if any term " assembling ", " connected ", " connection " term It should go to understand as broad sense, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；It can also be machine Tool connects；Can be joined directly together or be connected by intermediary, can be that two element internals are connected.For For those of ordinary skill in the art, it can understand that specific in the utility model of above-mentioned term containing as the case may be Justice.

In utility model, unless otherwise prescribed and limit, fisrt feature second feature it " on " or it " under " can be with Directly contacted including the first and second features, it is not directly to contact but pass through it that can also include fisrt feature and second feature Between other characterisation contact.Moreover, fisrt feature second feature " on ", " under " and " above " include fisrt feature Directly over second feature and oblique upper, or it is only to represent that fisrt feature level height is higher than the height of second feature.First Feature second feature " on ", " under " and " below " include fisrt feature immediately below second feature or obliquely downward, or only Only represent that fisrt feature level height is less than second feature.

With reference to the accompanying drawing of specification, by being further described to specific embodiment of the present utility model, make The technical solution of the utility model and its advantage are clearer, clear and definite.It is to show to describe embodiment below with reference to accompanying drawing Example property, it is intended to the utility model is explained, and it is not intended that to limitation of the present utility model.

As Figure 1-Figure 5, a kind of single head insertion-core lock, including：Knob 1, tumbler 2, turn part 3, lock gall 4 and lock housing 12, The tumbler 2, turn part 3, lock gall 4 is assembled in lock housing 12, the knob 1 is connected to one end of tumbler 2, the tumbler 2 other end is connected by turning part 3 with lock gall 4, and after key 5 inserts lock gall 4, lock gall 4 can be fixed by turning part 3 with tumbler 2, After key 5 exits lock gall 4, tumbler 2 can freely rotate relative to lock gall 4.

Wherein, it is connected between the knob 1 and tumbler 2 by connecting rod 6.Groove is provided with the end of tumbler 2 7, opening 8 is provided with the side wall of groove 7.

The part 3 that turns includes：Hollow housing 3-1, hollow housing 3-1 one end are socketed in groove 7, in groove 7 with The first spring 9 is provided between empty capsid 3-1；The first bayonet lock 3-2, the second bayonet lock 3-3 and work are provided with the hollow housing 3-1 other ends Dynamic core 3-4, the first bayonet lock 3-2, the second bayonet lock 3-3 are protruded outside hollow housing 3-1, and the first bayonet lock 3-2 is higher than the second bayonet lock 3-3；The bayonet socket 10 coordinated with the first bayonet lock 3-2, the second bayonet lock 3-3 is provided with the end of lock gall 4；Slide core 3-4 with it is hollow Second spring 3-5 is provided between housing 3-1.

Before key 5 inserts lock gall 4, first bayonet lock 3-2, the second bayonet lock 3-3 are all located in the presence of the first spring 9 In bayonet socket 10 on lock gall 4 and keep off outside groove 7, at this moment, turn free to rotate between part 3 and tumbler 2.Pass through turning knob 1 can be achieved the rotation of tumbler 2, be unlocked.

After key 5 inserts lock gall 4, the forward ends thereof slide core 3-4 of key 5 shrinks second spring 3-5, second spring 3-5 gives housing 3-1 mono- power moved into groove 7, at this moment, rotates lock gall 4, turns part 3 and rotated with lock gall 4, when first Bayonet lock 3-3 is turned to and slipped into automatically in opening 8 when being aligned with opening 8, is driven tumbler 2 to rotate realization together and is unlocked.Due to When first bayonet lock 3-3 is slided into opening 8, the second bayonet lock 3-4 is still located in bayonet socket 10, want to rotate tumbler 2 unlocks must be same Step rotates lock gall 4, and theftproof performance is good.
