Abstract

The utility model provides an antitheft fixing device, comprising a bolt having an external-angle nut and a screw. The antitheft fixing device is characterized in that a cylinder body is disposed on the external-angle nut; the end part of the cylinder body is provided with a pick-proof ball head and an opening machine matching with the bolt. Through the cooperation between the bolt and the opening machine, the fastening or loosening of the embedded type bolt can be conveniently achieved. When a common wrench or an inner hexagonal sleeve is in use, the common wrench or the inner hexagonal sleeve cannot contact with the bolt due to the obstruction of the pick-proof ball head of the bolt, the cylinder body and a stop pin, and thereby the fastening or loosening of the bolt can not be accomplished; a fastened door or cover can be effectively prevented from being opened at will, realizing true theft resistance. The antitheft fixing device is suitable for any open/close doors or covers.

Description

A kind of antitheft fixing device
Technical field
The utility model relates to a kind of antitheft fixing device, and especially a kind of fixedly anti-theft device that uses on all kinds of doors belongs to and uses the fixed block technical field.

Summary of the invention
The purpose of the utility model is to provide a kind of use at the lamp door or cover, and the antitheft fixing device on other all kinds of doors, through this anti-theft device, prevents that effectively all kinds of doors are opened easily.
The utility model provides a kind of like this antitheft fixing device; The bolt that comprises band exterior angle nut and screw rod; It is characterized in that the exterior angle nut is provided with cylindrical body, the cylindrical body end is provided with the pick-proof bulb, and is provided with opening of connecting of bolt and gets device; So that open get device and bolt and connect after, accomplish the fastening of bolt with loosening.
Said bolt circle cylinder is provided with at least one backing pin, is used to stop the nigger spanner to insert and contacts with nut.
Said backing pin is arranged on cylindrical bottom.
Said opening got device and comprised outer end band handle, and the pole of inner band interior angle sleeve after connecting with the exterior angle nut so that the inner interior angle sleeve of pole inserts, through handle rotation pole, and is accomplished tightening or loosening of bolt.
The said interior angle sleeve of getting device the inner of opening comprises the inboard cylindrical cavity and the interior angle chamber in the outside, and the interior angle lumen pore in outside footpath is adapter cavity between interior angle chamber and the cylindrical cavity, so that connect with bolt greater than the cylindrical cavity aperture of inboard.
Establish groove on the wall of said interior angle chamber, the backing pin on this groove and the bolt circle cylinder connects, and through connecting of groove and backing pin, can make interior angle spanner straight cutting to after the exterior angle nut cooperates, and can accomplish tightening or loosening of bolt.
The utility model compared with prior art has advantage and effect: adopt such scheme, i.e. one of which end band screw rod, the flush type bolt of the other end band cylindrical body and pick-proof bulb; And an end band handle, device is got in opening of the other end band interior angle sleeve, gets being used of device through bolt with opening; Can accomplish tightening or loosening of flush type bolt easily, and when using common wrench or interior Hexagonal jacket, owing to receive setting up defenses in depth and intercepting of bolt pick-proof bulb, cylindrical body and backing pin; They can't be contacted with bolt; Thereby can't accomplish tightening or loosening of bolt, prevent that effectively fastened door or lid from being opened arbitrarily, realize real antitheft effect.The utility model is applicable to any shutter door or covers.
