Abstract
The utility model provides an anti-theft screw/nut and an unscrewing sleeve of the anti-theft screw/nut and belongs to the technical field of anti-theft screws. The problems that an existing anti-theft screw is simple in structure and the problem that the existing anti-theft screw can be easily unscrewed can not be fundamentally solved are solved. According to the anti-theft screw/nut, one end of the anti-theft screw/nut is a cylinder and one or more axial inserting grooves are formed in the outer end face of the cylinder; the front end of the unscrewing sleeve used by the anti-theft screw/nut is provided with a groove used for containing the cylinder of the screw/nut and connecting plugs corresponding to the inserting grooves one to one and capable of being inserted into the inserting grooves are arranged at the bottom of the groove. According to the structural design of the anti-theft screw/nut and the unscrewing sleeve of the anti-theft screw/nut, design and combination of the inserting grooves are diversified, the screw/nut can be easily rotated only through the special unscrewing sleeve, and therefore the anti-theft screw/nut and the unscrewing sleeve of the anti-theft screw/nut have the advantages of being good in anti-theft performance, simple in structure, small in mold investment, low in cost, high in production efficiency and the like.
Description
Technical field
The utility model belongs to anti-theft screw technical field, refers in particular to a kind of anti-theft screw/nut and opens sleeve.
Background technique
HEX HEAD CAP SCREWS or nut are widely used in communal facility as fastening piece, such as electric power, communication, road, guardrail, bridge, steel tower etc., due to common HEX HEAD CAP SCREWS or nut, the design of its hexagonal is very convenient when installation and removal, use spanner easily to back out, also due to this convenience, make the theftproof performance of HEX HEAD CAP SCREWS or nut poor, brought very large unsafe factor to above-mentioned facility, can cause a large amount of property losses, therefore screw or nut that, a kind of theftproof performance is high become required.
At present, Chinese patent literature discloses a kind of anti-theft screw and sleeve thereof, and notice of authorization number (CN102400996A), mainly comprises nut, bolt and sleeve; It is characterized in that: described anti-theft screw consists of nuts and bolt, described nuts and bolt head is cone, is trapezoidal during side-looking; On the outer wall of described cone, arc convex is set, described arc convex has 3, between arc convex adjacent one another are, take the center of circle of nut or bolt as summit, forms 120 degree angles.This kind of sleeve that anti-theft screw is used, upper end is a hexagon, lower end arrange one with the endoporus of the described corresponding use of nuts and bolt; The setting arc groove corresponding with the arc convex of nut or bolt head on described inner hole wall, the sleeve that said structure has adopted special nut, bolt and has been used in conjunction with, but its structure is too single, sleeve is easily imitated, thereby cannot fundamentally solve bolt or the simple stolen phenomenon of nut unlatching.
Summary of the invention
The purpose of this utility model is that it is for existing bolt nut structure simplicity of design, the common tools such as spanner can easily turn the shortcoming that affects theftproof performance, have proposed a kind of simple and practical, theftproof performance is good, convenient for production, cost is low anti-theft screw/nut and have opened sleeve.
The purpose of this utility model is achieved in that
A kind of antitheft spiral shell screw/nut, is characterized in that: described screw or one end of nut are cylindrical body, offers more than one axial inserting groove on cylindrical exterior edge face.
In above-mentioned a kind of anti-theft screw/nut, described inserting groove is plural cylindrical hole, and the hole depth of cylindrical hole and aperture are all identical or not identical.
In above-mentioned a kind of anti-theft screw/nut, described inserting groove is a rectangular recess.
The unlatching sleeve using at above-mentioned a kind of anti-theft screw/nut, the front end of described unlatching sleeve is provided with the cylindrical groove holding on screw/nut, and the bottom land of described groove is provided with described inserting groove is corresponding one by one also can insert the connection-peg in inserting groove.
In above-mentioned unlatching sleeve, the rear end of described unlatching sleeve is provided with six angular protrusions that coordinate spanner to use.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the design of inserting groove and combine ever-changingly in structural design of the present utility model, must adopt easily rotary screw or nut of special unlatching sleeve, and therefore theftproof performance is good.
2, of the present utility model simple in structure, mould little investment, cost is low, and manufacturing efficiency is high.

Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-5:
A kind of antitheft spiral shell screw/nut, described screw 1 or one end of nut 2 are cylindrical body 3, offer more than one axial inserting groove on cylindrical exterior edge face 4.
Described inserting groove is plural cylindrical hole 6, and the hole depth of cylindrical hole and aperture are all identical or not identical.
Described inserting groove is a rectangular recess 7.
The unlatching sleeve that described a kind of anti-theft screw/nut is used, the front end of described unlatching sleeve 8 is provided with the cylindrical groove 9 holding on screw/nut, and the bottom land of described groove is provided with described inserting groove is corresponding one by one also can insert the connection-peg 10 in inserting groove.
The rear end of described unlatching sleeve is provided with six angular protrusions 11 that coordinate spanner to use.
Working principle of the present utility model is; On the head of screw or nut, be provided with cylindrical body 3, the boring of cylindrical exterior edge face or fluting design, wherein, the size of hole/groove depth, hole/groove and the position distribution of hole/groove can form N kind state, therefore corresponding unlatching sleeve is also along with change, this kind of screw/nut is because of the uniqueness of its structure, and theftproof performance is high.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
