CN203297279U - Novel nut - Google Patents

Abstract

The utility model discloses a novel nut. The novel nut is characterized by comprising a circular truncated cone body. An internal thread through hole is formed in the center of the circular truncated cone body. An extension part is integrally arranged on the end surface, with the larger diameter, of the circular truncated cone body and comprises a first extension portion and a second extension portion. The first extension portion is a convex arc-shaped extension portion provided with a through hole, the through hole is communicated with the internal thread through hole, and the central axis of the through hole is perpendicular to the central axis of the internal thread through hole. Sunken portions are symmetrically formed in the two end surfaces of the through hole and extend to the bottom end of the second extension portion along the outer contour of the through hole. The novel nut has the advantages that the extension part is arranged on a nut body and provided with the through hole and the sunken portions, a connection part such as a rope can penetrate through the through hole after the nut is fastened to a bolt, a screw and the like in a screwed mode, and therefore the functions of the nut is expanded, and the application range is wider.

Description

A kind of new type nut

Technical field

The utility model relates to a kind of threaded fastener, relates in particular to a kind of new type nut.

Background technique

Nut is exactly nut, is the part that is used for playing the role of fastening together with bolt or screw rod are screwed in.Conventional nut only has fastening effect usually, and function singleness, limited its application area.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of new type nut of simple in structure, diverse in function.

The utility model solves the problems of the technologies described above the technological scheme that adopts:

a kind of new type nut, comprise round table-like body, the center of described round table-like body is provided with an internal thread through hole, on the end face that on described round table-like body, diameter is larger, be wholely set an extension part, described extension part comprises the first extension part and the second extension part, the arc extension part that described the first extension part is evagination, on described arc extension part, be provided with a through hole, described through hole is connected with described internal thread through hole, the central axis of described through hole is vertical with the central axis of described internal thread through hole, the both ends of the surface of described through hole are symmetrically arranged with depressed part, described depressed part extends to the bottom of the second extension part along the external frame of through hole.

The bottom end of described the second extension part is plane.

Described through hole be shaped as triangle.

Compared with prior art, the utility model has the advantage of: extension part is set on nut body, on this extension part, be provided with through hole and depressed part, when this nut and bolt, screw rod etc. be spirally connected fastening after, but the link such as cross-under rope in through hole, make the function of nut be widened, application area is more extensive.

Embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing:

as Figure 1-4: a kind of new type nut, comprise round table-like body 1, the center of this round table-like body 1 is provided with an internal thread through hole 11, on the end face that on this round table-like body 1, diameter is larger, be wholely set an extension part 2, wherein, extension part 2 comprises the first extension part 21 and the second extension part 22, the first extension part 21 is the arc extension part of evagination, on the arc extension part, be provided with a through hole 23, this through hole 23 is connected with internal thread through hole 11, the central axis of through hole 23 is vertical with the central axis of internal thread through hole 11, the both ends of the surface of through hole 23 are symmetrically arranged with depressed part 24, depressed part 24 extends to the bottom of the second extension part along the external frame of through hole.

In this specific embodiment, the bottom end 221 of the second extension part 22 is plane.

In this specific embodiment, through hole 23 be shaped as triangle.
