Problems solved by technology

However, when pre-embedding, it is often impossible to determine the size and weight of the device to be installed in the future and the diameter of the installation screw used, so the pre-embedded nuts are either too small to be used, or they are overkill and cause serious waste.
Secondly, the impact force of concrete during pre-embedding can easily cause it to deviate from the predetermined position

Embodiment 1

[0030] see figure 1 , The nut of this embodiment includes a seat body 1, a nut assembly 2, a rubber gasket 3, a fixed cover 4 and a positioner 5.

[0031] see figure 1 , The seat body 1 is an integral piece of steel. The base 1 is provided with a cavity 11 with an upward opening. The shape of the upper part of the cavity 11 is a cylindrical shape, and the shape of the lower part of the cavity is a truncated cone shape with a large upper part and a smaller lower part. The upper inner wall of the cavity 11 is provided with a thread, which is also an internal thread on the upper part of the seat body 1. The outer shape of the seat body 1 corresponds to the shape of the cavity 11, that is, the seat body 1 is a shell with an upward opening. The center of the lower part of the base 1 is provided with a central through hole 12 communicating with the cavity 11, and the two are arranged coaxially.

[0032] see figure 1 with figure 2 , The nut assembly 2 is composed of a first petal nut ...

Abstract

The invention discloses a screw-free nut, which is characterized by comprising a base body, a nut assembly, a rubber gasket, a fixing cover and a positioner; the base body is a steel integrated piece;the base body is provided with a cavity with an upward opening; a central through hole communicating with the cavity is formed in the center of the lower part of the base body, and the base body andthe central through hole are coaxially arranged; the nut assembly is composed of a first nut piece, a second nut piece, a third nut piece and a fourth nut piece which are spliced in sequence; and eachnut piece is provided with a part of a nut internal thread; when the nut pieces are spliced together, a continuous nut internal thread of the nut assembly is formed. The nut assembly is arranged in the cavity of the base body, the fixing cover is fixedly connected with the base body, and the rubber gasket is arranged between the fixing cover and the nut assembly. The base body is arranged in a nut cavity of a mounting shell of the positioner.

Description

Technical field [0001] The invention relates to the field of mechanical parts, in particular to a nut that is free from rotation during installation. Background technique [0002] Nut connection is a simple and common method of detachable connection. The nuts commonly used in the market are rotating connection parts, which are not conducive to the quick installation of the nuts. Secondly, when used in some occasions (such as house decoration), in order to improve the fixing fastness of the nut, the nut can be pre-buried in the corresponding position when the concrete is poured to produce sufficient adhesion after pouring, and at the same time, the future drilling is reduced. Work greatly improves work efficiency. However, it is often impossible to determine the size and weight of the device to be installed in the future and the diameter of the mounting screw used when pre-embedded, so the pre-embedded nut may be too small to be used, or the large material will cause serious was...
