Description

The whip lock

Technical field

The utility model relates to a kind of lock.

Background technology

Existing lock is the structure more complicated at large, and generally is that a key is joined a lock, in particular cases uses and inconvenience at some.As personnel such as police, security personnel vehicle or other article violating the regulations are temporarily detained on the spot, or certain class people wishes that to the control of some passage, some pipeline, some switch its colleague can both open.Existing lock is difficult to satisfy this requirement.

The utility model content

The utility model provides a kind of lock simple in structure, easy to use.

The technical solution of the utility model is: comprise the lock body that contains lock tongue cavity and key hole, can be in described lock tongue cavity movable dead bolt, be used to latch bolt spring that described dead bolt is resetted, it is characterized in that: also have a flexible unidirectional ratchet whip, in lock body, also have one with described lock tongue cavity at the vertical hook tooth bullwhip cavity that communicates in dead bolt the tip of the tongue place, described key hole and described lock tongue cavity are on same axis, the whip head of described ratchet whip is fixed in the lock body, the whip tail can insert from an end of hook tooth bullwhip cavity and insert out at end from other, described dead bolt its root at least is that ferrous materials is made, and the mode of unblanking is to attract dead bolt with the special-purpose key identical with the key hole shape with strong magnetic.

Dead bolt can be " worker " font, also can be the cylinder of wedge shape, and correspondingly, lock tongue cavity can be made " worker " font or pillar buoy.If dead bolt is done the wedgewise cylinder, latch bolt spring can be placed lock tongue cavity, an end and lock tongue cavity top contact, the other end contacts with a certain position of dead bolt, allows latch bolt spring that dead bolt is resetted.

Adopt the utility model scheme, not only simple in structure but also easy to use, can satisfy some special requirements.

Description of drawings

Fig. 1 is a whip lock internal construction schematic diagram among the embodiment.

Fig. 2 and Fig. 3 are the cross sectional representation in two kinds of key holes.

The specific embodiment

As shown in Figure 1, whip lock provided by the utility model, mainly comprise lock body 1, a lock tongue cavity 2, key hole 5 and a hook tooth bullwhip cavity 7 vertical with lock tongue cavity 2 are arranged in lock body 1, dead bolt 3 places lock tongue cavity and can be movable at lock tongue cavity, and a latch bolt spring 4 is used to make dead bolt to reset, a flexible unidirectional ratchet whip 6, the whip head of ratchet whip is directly fixed in the lock body, and the whip tail can insert from an end of hook tooth bullwhip cavity and insert out from the other end.Dead bolt is to make with ferroic material, or its root of the tongue is partly made with ferroic material at least.The mode of unblanking is to insert in the key hole with the key identical with the key hole shape with strong magnetic to attract dead bolt.

When unidirectional ratchet whip inserted from hook tooth bullwhip cavity, dead bolt made the ratchet whip can not return and pin.When dead bolt being attracted from the key hole with key, the ratchet whip can withdraw from from hook tooth bullwhip cavity, so lock is opened.

In the embodiment shown in fig. 1, dead bolt and lock tongue cavity are all made " worker " font.

In another specific embodiment, dead bolt can be done the cylinder of wedgewise, and lock tongue cavity is correspondingly made pillar buoy, latch bolt spring places lock tongue cavity, one end and lock tongue cavity top contact, the other end contacts with a certain position of dead bolt, and it is just passable to allow latch bolt spring that dead bolt is resetted.

Triangularity, square, rhombus, different shape such as quincunx can be done in key hole in the utility model, and its key is made corresponding shape.Fig. 2 and Fig. 3 are two kinds of shapes of the cross section of key hole and corresponding key.

Ratchet whip in the utility model also can be discrete with lock body, as have the installation screw hole on lock body, in use lock body is fixed on certain post that is difficult to move, plate, railing or the wall, and the whip head of ratchet whip is fixed on the same object.Also can open a loculus at the back side of lock body, in use, the whip head of ratchet whip is put in this loculus, when being fixed in lock body on certain post that is difficult to move, plate, railing or the wall, the whip head of ratchet whip is just fixing together.
