Description

Inward hinge type safety theftproof device

The utility model relates to a kind of inward hinge type safety theftproof device that is applicable to house door, Hu Men, classroom door, office door etc.

At present, the theft of registering one's residence, house robbery incident frequently take place, and seriously jeopardize the people's the security of the lives and property and the operate as normal of relevant enterprises and institutions, make country, enterprises and individuals suffer great economic loss.Register one's residence theft, house robbery incident frequently takes place, and the trend that rises and spread is arranged greatly, become a social concern that needs to be resolved hurrily.Yet people are commonly used in theft preventing method such as iron chains formula in the inward, bolt-type and device but exists shortcomings such as unreasonable structure, anti-theft effect difference, and the back of particularly opening the door is difficult to stop the robber to register one's residence, enter the room, historical facts or anecdotes with in can not be satisfactory.

In order to overcome the shortcoming of existing inward with anti-theft device, special a kind of more reasonable structure, suitable production in enormous quantities, the good anti-theft effect of proposing, the inward hinge type safety theftproof device that particularly can stop the robber to register one's residence, enter the room effectively after opening the door is to remedy present deficiency.

According to the utility model, a kind of inward comprises at least one locating shaft ear piece and at least one bearing pin and at least one support member that cooperates with the locating shaft ear piece by bearing pin with the hinge type safety theftproof device, be processed with at least one axle sleeve that cooperates with bearing pin above the described support member, be processed with on the described locating shaft ear piece at least one axle ear that cooperates with bearing pin and at least one can be with the locking mechanism of support member locking, this inward with the hinge type safety theftproof device by its support member with door locked.Certainly, a kind of inward can also be to comprise at least one locating shaft external member and at least one bearing pin and at least one support member that cooperates with the locating shaft external member by bearing pin with the hinge type safety theftproof device, be processed with at least one axle ear that cooperates with bearing pin above the described support member, be processed with on the described locating shaft external member at least one axle sleeve that cooperates with bearing pin and at least one can be with the locking mechanism of support member locking, this inward with the hinge type safety theftproof device by its support member with door locked.Described locating shaft ear piece or locating shaft external member can become one by welding and ground; Can also fuse by hold-down screw and ground, locating shaft ear piece or locating shaft external member directly can also be processed and become one with ground on the ground.Locating shaft ear piece or locating shaft external member can have multiple shape, comprise circle, square, rectangle or the like.Axle ear or axle sleeve on locating shaft ear piece or the locating shaft external member, the hole on it can be a circular hole, can also be the hole of other shape.This anti-theft device can be contained in the appropriate location (when this anti-theft device was in closed condition, its support member preferably flushed with ground) of below ground of an indoor side of door, has a certain degree with the door structure.Support member can be the separate component of single-piece, can also be the assembly that is combined into one more than two or two.Support member can have multiple section shape, comprises circle, rectangle or the like.Locking mechanism can have multiple geometry, comprises flute profile, square or the like, in a word, preferably can be complementary with support member.Bearing pin can be a rivet, can also be pivot pin, can also be bolt or the like.Inward can be made by metal, timber, plastic or other material with the hinge type safety theftproof device, can pass through kinds of processes, forms as methods such as casting, die forging, cold-heading, machine, injection mouldings.

(see also Fig. 1 to Fig. 9) during use, the support member that will be installed on this underground anti-theft device with hand is pulled out from ground by its breach earlier, and the bearing pin axle center of taking advantage of a situation the bearing pin axle center that cooperates with support member and locating shaft ear piece and being connected support member A, support member B does to move around axle and support member is inserted locking mechanism puts in place and lock (seeing also Fig. 2), then door opened; At this moment, door can only be opened a slit and promptly live (because this moment, support member withstood door, door cannot being moved inwards around its door hinge) surely again, can only close the door outward, cannot open the door inwards again.In if robber's this moment can put in hand, also door cannot be opened (because the support member of this moment pins by the door roof pressure and by locking mechanism and formed certain included angle with door, if people's roof pressure door inwards arranged, the people in the door also support member cannot be mentioned reset and door opened).

When need are opened door this anti-theft device will be resetted the time, earlier door is outwards promoted around its door hinge, treat to shift door onto certain position, support member can be gone out from locking mechanism lira, and the bearing pin axle center of taking advantage of a situation the bearing pin axle center that cooperates with support member and locating shaft ear piece and being connected support member A spare, support member B spare does around axle and moves, and support member is put back in the supporting surface that resets; At this moment, this anti-theft device resets, door can be opened.

The utlity model has following major advantage: 1, rational in infrastructure, have good theftproof performance; 2, solved the difficult problem of registering one's residence, entering the room preferably the very difficult robber of prevention in the back of opening the door; 3, mature production technology, cost is low, installs simple and convenient; But 4 standardization can be exchanged general; 5, can with the supporting use of the inward of all size, compliance is strong; 6, easy to use, quick, safe and reliable.

Embodiment accompanying drawings of the present utility model is as follows:

This anti-theft device can have drawn from metal, timber, plastic or other material form through methods such as casting, die forging, cold-heading, machine, injection mouldings.
