Embodiment Construction

[0082] Hereinafter, a cap nut 10 according to an embodiment of the present invention will be described with reference to the drawings.

[0083] Figure 2 ~ Figure 6 Indicates the main body part 20 of the cap nut 10, Figure 7 ~ Figure 10 The nut member 30 of the cap nut 10 is shown. Picture 11 It shows the state before the main body member 20 and the nut member 30 are combined, Figure 12 ~ Figure 15 The state where the main body member 20 and the nut member 30 are coupled is shown. Figure 16 Shows the state where the cap nut 10 is mounted on the mounted component 41, Figure 17 This shows a state where the mounting member 42 is mounted on the cap nut 10 of the mounted member 41 using the bolt 45.

[0084] The cap nut 10 of the embodiment of the present invention includes a main body member 20 formed of a plastically deformable material such as metal, and a nut member 30 formed of a rigid material such as metal. Such as Picture 11 As shown, the nut member 30 is inserted from the ...

Abstract

Provided is a blind nut which has a small height after being fastened, has a small outer diameter, and is lightweight. A blind nut (10) which is to be mounted in a mounting hole (43) in a member (41)to which the blind nut (10) is to be mounted is provided with: a body member (20) formed from a plastically deformable soft material; and a nut member (30) formed from a hard material. The body memberhas: a cylindrical first cylindrical section (21); a hexagonal cylindrical second cylindrical section (22) adjacent to the first cylindrical section; and a flange (24) adjacent to the second cylindrical section, and center holes (25, 26) are formed in the body member. The nut member has a short circular cylindrical nut base section (31) and has nut circular cylinder sections (32, 33) adjacent tothe nut base section and having smaller outer diameters than the nut base section. A through-hole (35) having a female thread (37) formed along the entire length thereof is formed in the nut member. The nut circular cylinder sections of the nut member are disposed inside the first cylindrical section and the second cylindrical section, which belong to the body member. The lower end of a body cylindrical section is in contact with and welded to the stepped section (31a) of the nut base section.

Description

Technical field [0001] The invention relates to a cap nut and its mounting structure. In particular, it relates to a fastened low-height cap nut and an installation structure for installing the cap nut on a component to be installed. Background technique [0002] The cap nut includes a female screw portion with a female screw formed on the inside, a hollow tubular portion adjacent to the female screw portion, and a flange provided with an end of the tubular portion. With the tubular part of the cap nut inserted into the mounting hole of the mounted component and the flange is in contact with the surface of the mounted component, use a tightening tool to plastically deform the tubular part in an expanded diameter manner to clamp the mounted component Between the deformed tubular portion and the flange. In this way, the cap nut is fixed to the mounted component. The external thread of the bolt is engaged with the internal thread portion of the cap nut fixed to the mounted compon...
