Description

Antitheft bolt

Technical Field

The utility model relates to the technical field of bolts, in particular to an anti-theft bolt.

Background

The bolt is a mechanical part, is matched with a stud-shaped threaded fastener of a nut, is a fastener consisting of a head part and a screw rod (a stud body with external threads), and is matched with the nut to be used for fastening and connecting two parts with through holes, the bolt in the prior art is common and does not have an anti-theft function, and at present, a plurality of municipal and common facilities and equipment are often stolen, stolen and damaged, such as a manhole cover, a transformer, street lamp facilities, cables and the like; if the conventional bolts or the simple lock heads are used for theft prevention during installation of the facilities and the equipment, the facilities and the equipment can be easily damaged and stolen, so that huge losses are caused; the existing anti-theft bolt with higher safety has higher production cost, low input-output ratio and is not suitable for large-scale use,

therefore, the anti-theft bolt is simple in structure, safe, reliable, small in size, firm and durable.

Disclosure of Invention

The technical problem to be solved by the utility model is to overcome the defects of the technology and provide an anti-theft bolt.

In order to solve the technical problems, the technical scheme provided by the utility model is that: the novel anti-theft device comprises a column body, a cylinder and a stud, wherein an inner screw hole is formed in the other end of the column body, the inner screw hole penetrates through the column body, the stud is arranged in the inner screw hole at one end of the column body, a baffle is arranged at the end, far away from the column body, of the stud, and the cylinder is sleeved on the stud;

the cylinder is provided with a notch.

As an improvement, the diameter of the stud is smaller than the inner diameter of the cylinder.

As a modification, the shape of the baffle is circular.

As an improvement, the outer diameter of the cylinder is larger than the baffle diameter.

Compared with the prior art, the utility model has the advantages that: the interior of cylinder is equipped with interior screw, can install this theftproof bolt on the screw through interior screw, the one end of cylinder is equipped with the double-screw bolt, the tip of double-screw bolt is equipped with the baffle, the drum cover is on the double-screw bolt, the shape of baffle is circular, the external diameter of drum 2 is greater than baffle 4 diameters, make the drum end stay outside after the installation, the drum can effectually prevent to unscrew the bolt through spanner instrument after theftproof bolt is installed like this, can play fine theftproof effect, this product simple structure, safe and reliable, small and sturdy and durable, low in production cost, can extensive use.

Detailed Description

The anti-theft bolt of the utility model is further described in detail below with reference to the accompanying drawings.

1-2, an anti-theft bolt comprises a column body 1, a cylinder 2 and a stud 3, wherein an inner screw hole 6 is formed in the other end of the column body 1, the inner screw hole 6 penetrates through the column body 1, the stud 3 is arranged in the inner screw hole 6 at one end of the column body 1, a baffle 4 is arranged at the end, far away from the column body 1, of the stud 3, and the cylinder 2 is sleeved on the stud 3;

the cylinder 2 is provided with a notch 5.

The diameter of the stud 3 is smaller than the inner diameter of the cylinder 2.

The shape of the baffle 4 is circular.

The outer diameter of the cylinder 2 is larger than the diameter of the baffle 4.

When the anti-theft bolt is used, the other end of the cylinder 1 is provided with the inner screw hole 6, the anti-theft bolt can be installed on a screw through the inner screw hole 6, one end of the cylinder 1 is provided with the stud 3, the end part of the stud 3 is provided with the baffle 4, the cylinder 2 is sleeved on the stud 3, the baffle 4 is circular, the end of the cylinder 2 is left outside after the anti-theft bolt is installed, the outer diameter of the cylinder 2 is larger than the diameter of the baffle 4, so that the cylinder 2 can effectively prevent the bolt from being unscrewed through a spanner tool after the anti-theft bolt is installed, a good anti-theft effect can be achieved, and the anti-theft bolt is simple in structure, safe, reliable, small in size, firm, durable, low in production cost and capable of being widely used.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
