Gap, from outdoors reversely scratching cuff link along paddle-tumble, thus quietly in the case where not destroying anti-theft chain lock at night
Into.
Therefore, still there is some security risks for existing anti-theft chain, it is necessary to structure improvement is carried out, to eliminate this
Kind security risk.
Summary of the invention
The technical problems to be solved in the utility model is to solve anti-theft chain in the prior art there are the technologies of security risk
Defect.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is provided is as follows: a kind of self-locking antitheft chain,
Including at least slot and cuff link, the slot include metal bracelet and be respectively arranged on metal bracelet both ends slot fixing end and
Slot movable end；The cuff link slide-in end and cuff link end at sliding slot both ends are buckled equipped with sliding slot and be respectively arranged on to the chain；Further include
Self-locking device, the self-locking device include at least self-locking flip lid and the hinge for connecting self-locking flip lid and cuff link, self-locking state
Under, the self-locking flip lid covers the sliding slot.
A kind of preferred embodiment, the self-locking flip lid are equipped with embedded division compatible with the sliding slot.
A kind of preferred embodiment, the cuff link are in a horizontal state fixation.
A kind of preferred embodiment, the fixation position of the slot fixing end and cuff link are located at same horizontal line.
A kind of preferred embodiment, the cuff link end is close to slot fixing end side.
The self-locking antitheft chain of the present embodiment, the slot movable end of slot slide into end by the cuff link of cuff link and are divided into along the chute
Behind cuff link end, self-locking flip lid is overturn to the sliding slot is covered, slot movable end can be effectively prevented from crack between a door and its frame using work
A possibility that tool is reversely scratched, to increase the safety of anti-theft chain lock；When not in use, self-locking flip lid is made in gravity
It is naturally drooped under, prevents maloperation, structure is simple, and easy to use, functional structure is very clear, does not need instructions direct i.e.
It can be used, used particularly suitable for the public place of renting a house such as hotel, shared people place.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the present embodiment self-locking antitheft chain.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain this hair
It is bright, it is not intended to limit the present invention.
As shown in Figure 1, a kind of self-locking antitheft chain lock of the present embodiment, structure is big solely by slot 103 and 111 liang of cuff link
Vertical part forms.Wherein slot 103 includes metal bracelet 112 and 102 He of slot fixing end set on 112 both ends of metal bracelet
Slot movable end 110.Wherein cuff link 111 is equipped with sliding slot 108 and is respectively arranged on the cuff link slide-in end 104 at 108 both ends of sliding slot
With cuff link end 105.
It further include self-locking device as the maximum improvement of the present embodiment, which includes at least 106 Hes of self-locking flip lid
For connecting self-locking flip lid and the hinge 107 of cuff link, under self-locking state, above-mentioned self-locking flip lid is covered on sliding slot.Preferably,
The self-locking flip lid is equipped with embedded division (not shown) compatible with the sliding slot.
Under installation condition, as shown in Figure 1, cuff link 111 is mounted on a back 100, cuff link slides into end 104 and cuff link end
105 be to be horizontally mounted；Cuff link end 105 is mounted on 101 proximal end of doorframe, and cuff link slides into end 104 and is mounted on 101 distal end of doorframe.
Slot 103 is fixed on doorframe 101 by the slot fixing end 102 of slot 103, and slot 103 and cuff link 111 are located at the same level
On line.Slot movable end 110 slides into end 104 from cuff link and slides into sliding slot 108, and horizontally slips in sliding slot 108, slot movable end
110 are stuck in the position of entire sliding slot 108 and cuff link end 105, only can be detached from cuff link in the position that cuff link slides into end 104
