Abstract

A nut structure comprises a nut body, wherein the nut body is divided into a screwing area and a threaded connection area along the axial direction of a nut, the screwing area is arranged on the upper surface of the threaded connection area, threads are arranged in the threaded connection area, and the thread specifications of the threads are selected according to standards; the screwing area is of a boss structure, a safety hole for preventing loosening by using a fuse after nut connection is formed in the boss, and the side length of the boss is selected according to the tightening torque intensity requirement and according to a standard series; the hexagonal nut screwing device has the advantages of being simple in structure and small in required screwing operation space, effectively solving the problem that a common hexagonal nut is difficult to apply in a narrow space environment, needing no special tools during use, being capable of completing operation by using a standard wrench, and being wide in application range.

Description

Nut structure

Technical Field

The utility model relates to a fastener technical field especially relates to a nut structure.

Background

The stud/nut connecting structure is a common force-bearing threaded connection form, and the nut is usually a common hexagon nut, and when the stud/nut connecting structure and the nut are screwed together, a spanner is used for clamping a hexagon head of the nut and screwing the hexagon head. When the connecting piece is limited by the structure size, and the space between the hexagonal head nut and the connecting piece is not enough for the operation of the wrench, the nut is difficult to be screwed, and the connection of the connecting piece is seriously influenced.

SUMMERY OF THE UTILITY MODEL

The technical problem solved by the utility model is to provide a nut structure to solve the problem in the above-mentioned background art.

The utility model provides a technical problem adopt following technical scheme to realize:

a nut structure comprises a nut body, wherein the nut body is divided into a screwing area and a threaded connection area along the axial direction of a nut, the screwing area is arranged on the upper surface of the threaded connection area, threads are arranged in the threaded connection area, and the thread specifications of the threads are selected according to standards; the screwing area is of a boss structure, meanwhile, a safety hole used for preventing looseness of the nut after connection is formed in the boss through a fuse, and the side length of the boss is selected according to the tightening torque intensity requirement and standard series.

In the present invention, the threaded connection region is a cylindrical structure.

The utility model discloses in, threaded connection district inside still is provided with the tool withdrawal groove.

The utility model discloses in, the boss is the hexagon boss, and the size of hexagon boss is less than the size with specification hexagon head nut.

The utility model discloses in, the insurance hole is the symmetry setting on the hexagon boss.

The utility model discloses in, use the utility model discloses a during the nut installation, utilize the spanner to block behind the nut body and the double-screw bolt contact and screw up the district and apply moment to accomplish the nut body and close soon of double-screw bolt, treat that the nut body closes soon with the double-screw bolt and utilize the insurance hole that sets up on the hexagon boss to carry out locking can.

Has the advantages that:

1) the utility model has the advantages of simple structure and small space for screwing operation, and effectively solves the problem that the common hexagon nut is difficult to be applied in the narrow space environment;

2) the utility model can be used without special tools and can be operated by using a standard wrench;

3) the utility model discloses application scope is wider, is applicable to the installation of connecting pieces such as double-screw bolt, bolt under the narrow space environment.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1-5, a nut structure includes a nut body 1, a screwing region 2, a safety hole 3, a thread connection region 4, a tool withdrawal groove 5 and a thread 6, wherein the nut body 1 is divided into the screwing region 2 and the thread connection region 4 along an axial direction (i.e., a screwing direction) of the nut, the thread connection region 4 is a cylindrical structure, the tool withdrawal groove 5 and the thread 6 are arranged inside the cylindrical structure, a thread specification M of the thread 6 is selected according to a standard, the screwing region 2 is a hexagonal boss, the hexagonal boss is smaller than a hexagonal head nut of the same specification in size, and the hexagonal boss is provided with the safety hole 3 for preventing loosening by using a fuse after the nut is connected; the side length S of the hexagonal boss is selected according to the tightening torque intensity requirement and standard series.

In the present embodiment, the safety holes 3 are symmetrically arranged on the hexagonal boss.

In this embodiment, the use occasion is as shown in fig. 5, 7 is the double-screw bolt, 8, 9 are the connecting piece, 10 is the packing ring, 11 is the spring washer, to this narrow space region, uses the utility model discloses a nut, during the installation, utilize the spanner to block to tighten district 2 and exert moment after contacting nut body 1 and double-screw bolt 7 to accomplish nut body 1 and the closure of double-screw bolt 7 soon, nut body 1 utilizes the safety vent 3 that sets up on the hexagon boss to lockingly after 7 soon with the double-screw bolt.
