Embodiment

[0019] A kind of anti-dismounting nut of the present invention, as figure 1 As shown, including nut base 1 and nut 2;

[0020] Such as figure 2 As shown, the nut base 1 is a cylindrical piece with openings at both ends. The inner and outer walls of the nut base 1 are respectively processed with internal threads and external threads with the same direction of rotation. The bit platform is processed with a wrench groove on the outer wall of the nut base 1;

[0021] The nut 2 is a ring whose length matches the length of the nut base 1. The inner wall of the nut 2 is processed with an internal thread matching the outer thread of the nut base 1. The outer wall of the nut 2 is a hexagonal cylindrical surface; the nut 2 is threaded Screw into the outer wall of the nut base 1 until the front end of the nut 2 tightens the annular limiter at the locking end of the nut base 1; the tightness of the screw connection between the nut 2 and the nut base 1 is less than that of the nut base ...

Abstract

The invention relates to an anti-demounting nut, and belongs to the field of fasteners. The anti-demounting nut comprises a nut matrix and a screw cap. An internal thread and an external thread identical in thread turning direction are machined in the inner wall and the outer wall of the nut matrix correspondingly. The end of the locking end of the nut matrix extends outwards to form an annular limiting table, and a wrench groove is machined in the outer wall of the nut matrix. An internal thread matched with the external thread on the outer wall of the nut matrix is machined on the inner wallof the screw cap, and a polygon prism face is arranged on the outer wall of the screw cap. The screw cap is screwed into the outer wall of the nut matrix in a threaded manner until the front end faceof the screw cap abuts against the annular limiting table at the end of the locking end of the nut matrix. The tightness of threaded connection of the screw cap and the nut matrix is smaller than that of threaded connection of the nut matrix and a bolt. The anti-demounting nut is reliable in anti-demounting effect, and meets the special demounting needs of maintenance, equipment replacement and the like at the same time.

Description

technical field [0001] The invention relates to an anti-disassembly nut, which belongs to the field of fasteners. Background technique [0002] Since the traditional nut does not have the anti-disassembly function, after locking, it can be easily disassembled with a general-purpose tool; Locking nuts, such as bridge fastening, communication equipment fastening, and security mechanism fastening; but in special cases, when professionals perform operations such as maintenance and equipment replacement, anti-disassembly nuts must also meet professional disassembly requirements . [0003] Traditional anti-disassembly nuts are generally divided into two forms: [0004] One form is to adopt a twist-off anti-disassembly structure. Specifically, the nut body has a cylindrical section and a twisted part of the hexagonal head. The inner hole of the cylindrical section is a threaded hole for matching with the thread. The inner hole of the hexagonal head is a thread Large through hole...
