Abstract

The utility model discloses an anti-burglary nut. The anti-burglary nut comprises a nut body, wherein the top surface of the nut body is an arc surface, a screw hole is formed in the nut body, a plurality of fixed holes are formed in the nut body, and the depths of all fixed holes are different. The anti-burglary nut and supporting tools provided by the utility model are simple and practical in structure.

Description

Anti-theft nut and kit thereof

Technical field

The utility model relates to nut, especially a kind of nut with anti-theft feature with and supporting special tool, belong to metal fastenings technical field.

Background technique

The upper surface of nut was generally square or Hexagon in the past, can tighten or loosen with general spanner.In the time of the outdoor area application nuts such as high speed guardrail, in order to reach antitheft requirement, often by after nut screwing clamping, with iron hammer, screw is beaten to distortion, reach antitheft requirement, but very strong to the destructiveness of nut itself like this, run into situation about needing repairing.

Model utility content

The utility model is in order to overcome above shortcomings part in existing nut, provides a kind of and is mainly used in outdoorly, and nut that can be effectively antitheft and special spanner, can be effectively antitheft, prevents dangerous generation.

An object of the present utility model is to provide a kind of anti-theft nut:

Specifically, anti-theft nut described in the utility model, comprises that end face is the nut body of arc surface, has screw on nut body, has several fixed holes on nut body, and the degree of depth of each fixed hole is inconsistent.

Further, the irregular distribution of described fixed hole.

Further, the shape of described fixed hole is inconsistent.

Another object of the present utility model is to provide and the matching used special tool of above-mentioned anti-theft nut, can be used for described nut check or unscrews:

Specifically, the kit of described anti-theft nut, comprise that bottom surface is the installation body of arc-shaped concave, the arc surface of arc-shaped concave and aforementioned nut body cooperatively interacts, under arc-shaped concave, stretching out several and aforementioned fixed hole cooperatively interacts and can insert respectively the fixing column in described fixed hole, body is installed and is provided with and the rotating component of body being installed being fixedly connected with, have and screwhole position on aforementioned nut body corresponding through hole mutually on rotating component, via openings is in arc-shaped concave.

Further, described rotating component is prismatic, and the spanner clamping of routine easy to use, for rotating described anti-theft nut.

Further, described fixing column is unique corresponding respectively with the fixed hole of above-mentioned nut body, and fixing column is unique with the corresponding of fixed hole, and the fixed hole of difformity, size, the depth can only be unique corresponding to corresponding fixing column.

Anti-theft nut described in the utility model and kit thereof, simple and practical, the nut body of arc surface make the instruments such as common spanner closely interlock fix, cannot rotate, must use special kit, its concave surface is engaged with nut body, and corresponding fixing column is inserted in fixed hole, then the rotating component that rotates the regular shape of kit top, reaches the folding of described anti-theft nut.

Wherein, 1 is that nut body, 10 is that screw, 11 is that fixed hole, 2 is that through hole, 21 is that arc-shaped concave, 22 is that fixing column, 23 is rotating component for body, 20 is installed.

Embodiment

Below in conjunction with accompanying drawing, described technology contents is carried out to nonrestrictive description, object is understood described technology for the public is better.

As shown in Figure 1, anti-theft nut described in the utility model, comprise that end face is the nut body 1 of arc surface, on nut body 1, have screw 10, on nut body 1, have several fixed holes 11, the degree of depth of each fixed hole 11 is inconsistent, the irregular distribution of described fixed hole 11, and the shape of fixed hole, size, size are all inconsistent.

As Fig. 2-4, kit described in the utility model, comprise that bottom surface is the installation body 2 of arc-shaped concave 21, arc-shaped concave 21 cooperatively interacts with the arc surface of aforementioned nut body 1, arc-shaped concave stretches out several and aforementioned fixed hole 11 for 21 times and cooperatively interacts and can insert respectively the fixing column 22 in described fixed hole 11, body 2 is installed to be provided with and the rotating component 23 of body 2 being installed being fixedly connected with, on rotating component 23, have and screw 10 positions on aforementioned nut body 1 corresponding through hole 20 mutually, through hole 20 is opened on arc-shaped concave 21, described rotating component 23 is regular shape, can be for example prismatic, comprise the common regular shapes such as six prisms or quadrangular, the spanner clamping of routine easy to use, be used for rotating described anti-theft nut, further, described fixing column 22 is unique corresponding respectively with the fixed hole 11 of above-mentioned nut body 1, and fixing column 22 is unique with the corresponding of fixed hole 11, and the fixed hole of difformity, size, the depth can only be unique corresponding to corresponding fixing column.

When use, the screw of described anti-theft nut 10 is enclosed within on corresponding bolt, then kit is enclosed within on nut body, use conventional instrument (for example spanner) to be rotated locking to the rotating component on kit, in the time that needs unclamp, also kit is enclosed within to counterrotating rotating component on nut body.

It should be understood that, foregoing description comprises the not restriction to described technological scheme of accompanying drawing, in fact, any improvement to described structure under identical or approximate principle, so comprise the change of shape, size material, to realize basic identical function as object, all within the desired technological scheme of the utility model.
