Description

Tensioning nut

Technical Field

The utility model relates to the technical field of screws, in particular to a tensioning nut.

Background

The bolt is widely applied to detachable connection in mechanical manufacturing, usually, one or two washers are added between a bearing surface of the bolt, a screw, a nut and the like and a workpiece bearing surface to play a role in preventing looseness and reducing bearing surface stress, the bolt is generally matched with the nut for use, the conventional common nut can be freely detached, but in some application occasions, the nut is required to be fixed on a mounting plate, the bolt is movably mounted, and aiming at the mounting requirement, a tensioning nut is developed and can be tensioned to be locked at a fixed position through an electric drill.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a tensioning nut which can be installed on one side of an installation hole, is stable in structure after installation and has a good fastening effect with a bolt.

The utility model provides a tensioning nut, the nut includes outer helicoid, shell fragment, interior helicoid and helicoid bottom, be equipped with the through hole of equidimension on outer helicoid, interior helicoid and the helicoid bottom, interior helicoid sets up on the helicoid bottom, the shell fragment is connected at outer helicoid and helicoid bottom, seals up interior helicoid between outer helicoid and helicoid bottom.

Furthermore, internal threads rotating in the same direction are arranged in the through hole.

Furthermore, the elastic sheet is in a symmetrical pattern, the two connecting ends are narrow, the middle section is wide, and the middle section of the elastic sheet can deform outwards.

Furthermore, the outer spiral ring, the elastic sheet, the inner spiral ring and the spiral ring bottom are integrally formed.

The utility model has the beneficial effects that: the tensioning nut of this structure, integrated into one piece during the installation, is treating one side of mounting hole and is packed into the nut, adopts the tensioning nut of screw instrument, can accomplish the installation, and the nut after the tensioning plays the clamping action jointly by outer helicoid and inside outside shell fragment that takes place to warp, fixes the nut in the mounting hole, prevents to become flexible simultaneously.

Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification.

As shown in fig. 1-3, a tensioning nut comprises an outer coil 1, an elastic sheet 2, an inner coil 3 and a coil bottom 4, wherein through holes 5 with the same size are arranged on the outer coil 1, the inner coil 3 and the coil bottom 4, and internal threads 6 rotating in the same direction are arranged in the through holes 5; the inner coil 3 is arranged on the coil bottom 4, the elastic sheet 2 is connected with the outer coil 1 and the coil bottom 4, and the inner coil 3 is sealed between the outer coil 1 and the coil bottom 4. The outer coil 1, the elastic sheet 2, the inner coil 3 and the coil bottom 4 are integrally formed by metal materials.

The elastic sheet 2 is a symmetrical figure, the two connecting ends are narrow, the middle section is wide, and when the inner spiral ring 3 of the nut moves upwards, the middle section of the elastic sheet 2 deforms outwards.

The working principle is as follows: when the tensioning nut is used, the nut is tensioned at the outer ring end by adopting a screw pulling tool at the ring bottom end of the nut loaded at one side of the mounting hole, the nut after tensioning can be mounted, the outer ring and the internal outward deformed elastic sheet jointly play a clamping role, the nut is fixed in the mounting hole, the mounting is convenient, the positioning is accurate simultaneously, and the loosening prevention effect is good.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
