Abstract
Disclosed is a loosening-proof and guarding against theft screw cap which comprises a nut, a hexagon sleeve and a pin. A cylinder-shaped nut which an outer end face of the nut is provided with a convex platform is inserted into the hexagon sleeve having a corresponding annular groove and matching with the nut, which becomes a combined screw cap. A blind pin hole is arranged on end surface inside the combined screw cap along the axial direction of the matched surface. Pins are provided in the blind pin hole. On the base of the tightening face of the nut, an axial gap exists between the nut and the hexagon sleeve. In general, the nut is tightened by the wrench but so long as the nut is tightened by the overload torque, the pin of the nut can be cut. At this time the hexagon sleeve on the nut turns just only without load and can be not removed, reaching the purpose of the loosening-proof and guard against theft. This loosening-proof and guarding against theft screw cap has the following advantages of novel idea, special structure, convenient operation, saving time and labour, firm join, high efficient safety, unable remove by the general wrench, a wide range of applications, and particularly is suitable for the power equipments.
Description
Technical field the utility model relates to a kind of fastening piece, specifically is meant a kind of anti-loose anti-theft nut.
Its main structure of the disclosed model utility mariages cover of background technique anti-loose anti-theft nut (patent No. 00230944.0) is in six sides cover circular hole, respectively adorn a silk braid that has boss from both sides, there is n pin-and-hole this silk braid outer wall and six side's trepanning inwall contacting points, be provided with pin in the pin-and-hole, rotate six side's cover screwing silk braids during use, fastening back incision half part pin makes the idle running of six sides cover and can't drive silk braid and rotates, thereby reaches the purpose of anti-loose anti-theft.Its deficiency is that complex structure, operation inconvenience, application area are restricted.
The summary of the invention the purpose of this utility model is to overcome deficiency of the prior art, and a kind of simple in structure, easy to operate anti-theft screw cap is provided.The purpose of this utility model realizes by following technique measures: this anti-loose anti-theft nut, it includes nut, hexagonal cover, pin, it is characterized in that: barrel nut is inserted in the hexagonal cover, constitute combination nut, on the inner side end of combination nut, be provided with blind pin hole, be provided with pin in its blind pin hole along the fitting surface axial direction.The nut exterior edge face has boss, and the hexagonal cover that matches with it has the corresponding annular groove.Locking face with nut is a benchmark, and nut and hexagonal cover have axial clearance.Rotate the hexagonal cover during use, fastening nut, when the overload moment of torsion of screwing force took place, pin was cut off, and the hexagonal cover can only dally on nut, can't dismantle, and has reached the purpose of anti-loose anti-theft.This anti-loose anti-theft nut compared with prior art has following advantage: novel, structure is unique, easy to operate, time saving and energy saving, connect firm, safe and efficient, use conventional wrench can't dismounting, applied range, be particularly suitable for using on the power equipment.
Description of drawings
Fig. 1 is the utility model plan view.
Fig. 2 is the worm's eye view of Fig. 1.
Embodiment now is further described the utility model in conjunction with the accompanying drawings: with reference to Fig. 1, Fig. 2, this anti-loose anti-theft nut, it includes nut, hexagonal cover, pin, the barrel nut 1 that the nut exterior edge face has boss is inserted in the hexagonal cover 2 that has the corresponding annular groove that matches with it, constitute combination nut, on the inner side end of combination nut, be provided with blind pin hole, be provided with pin 3 in its blind pin hole along the fitting surface axial direction.Locking face with nut is a benchmark, and nut and hexagonal cover have axial clearance.Use the wrench fastening nut, when the overload moment of torsion of screwing force took place, pin was cut off, and the hexagonal cover can only dally on nut, can't dismantle, and has reached the purpose of anti-loose anti-theft.
