Abstract

The utility model discloses a fast-assembling nut, including outer hexagon nut body, the center of outer hexagon nut body is equipped with axial direction's internal thread hole, its characterized in that: except the upper part of the internal thread hole, the hole wall of the threaded hole at the middle lower part is provided with a notch in the circumferential direction, and the aperture of a local unthreaded hole formed by the circumferential notch is larger than the maximum thread aperture of the internal thread hole. The utility model discloses can carry out the nut and be connected with the fast-assembling that corresponds the bolt, improve assembly efficiency.

Description

Fast-assembling nut
Technical Field
The utility model relates to a fastener product, concretely relates to outer hexagon nut.
Background
Outer hexagon nut is most common in the fastener product, and outer hexagon nut is when using, and the internal thread hole of nut need begin to twist from the one end of bolt, and until the nut is screwed up, whole twisting process need spend more time, and assembly efficiency is low.
Disclosure of Invention
In view of the problems existing in the prior art, the to-be-solved technical problem of the present invention is to provide a quick-assembling nut which can be connected with a corresponding bolt in a quick-assembling manner and can improve the assembling efficiency.
The utility model discloses a through following technical scheme implementation:
fast-assembling nut, including outer hexagon nut body, the center of outer hexagon nut body is equipped with axial direction's internal thread hole, its characterized in that: except the upper part of the internal thread hole, the hole wall of the threaded hole at the middle lower part is provided with a notch in the circumferential direction, and the aperture of a local unthreaded hole formed by the circumferential notch is larger than the maximum thread aperture of the internal thread hole.
The circumferential notches are symmetrically arranged along the circumference of the hole wall of the threaded hole, and the circumferential angles of the two circumferential notches are larger than 90 degrees.
According to the quick-mounting nut in the technical scheme, when the quick-mounting nut is in threaded connection with a corresponding bolt (the external thread of the bolt is provided with the circumferential notch which is the same as that of the nut), the internal thread hole of the nut is firstly linearly sleeved into the excircle of the bolt until the internal thread hole at the upper part of the nut (the internal thread hole at the upper part of the nut is a full threaded hole without the notch) is abutted against and contacted with the head of the bolt, and then the nut is screwed until the thread is screwed, so that the time of the screwing process is greatly shortened, and the assembly efficiency is improved; of course, in order to ensure the connection strength, the angle of the nut when the nut is screwed is preferably different from the angle when the nut starts to be screwed by about 90 degrees, the notch of the nut is opposite to the notch of the bolt, and the internal thread of the nut and the external thread of the bolt are just in thread contact state. In fact, the biggest advantage of above-mentioned fast-assembling nut is can be applied to the machine wallboard and has the side opening, the high little connection occasion of side opening, and under this kind of occasion, the angle of pulling of nut is little, and in the bolt penetrated the side opening from the bottom direction in addition, the twisting of bolt was moved difficult operation and easily produced the syntropy with the nut and is rotated.
Drawings
The utility model discloses there is following figure:
figure 1 is a top view in the direction of the present invention,
fig. 2 is a view a-a of fig. 1.
Detailed Description
The details and the working principle of the embodiments of the present invention are described in detail below with reference to the accompanying drawings:
as shown in the figure, the utility model discloses a fast-assembling nut, including outer hexagon nut body 1, the center of outer hexagon nut body 1 is equipped with axial direction's internal thread hole 2, and internal thread hole 2 is equipped with the breach 3 of circumference direction on the internal thread hole pore wall of well lower part except upper portion 21, and the aperture of the local unthreaded hole 4 that this circumference breach 3 formed is greater than the maximum thread aperture of internal thread hole 2, two places of symmetry are laid along 2 pore wall circumferences in internal thread hole to circumference breach 3, and the angle of circumference of two places circumference breach 3 all slightly is greater than 90 degrees. In the quick-mounting nut with the design, the corresponding bolt is also provided with two symmetrical notches on the outer thread, and the circumferential angles of the two notches are slightly larger than 90 degrees. When the nut is connected with the bolt, firstly, the gap of the nut and the gap of the bolt are staggered by 90 degrees, so that the internal thread hole of the nut can be sleeved into the excircle of the bolt in a straight line until the internal thread hole at the upper part of the nut is abutted against the head of the bolt, then the nut is screwed until the thread is screwed, in order to ensure the connection strength, the angle of the nut when being screwed is best about 90 degrees with the angle difference when the nut is screwed, namely, the gap of the nut is just opposite to the gap of the bolt at the moment.

Claims (2)

1. Fast-assembling nut, including outer hexagon nut body, the center of outer hexagon nut body is equipped with axial direction's internal thread hole, its characterized in that: except the upper part of the internal thread hole, the hole wall of the threaded hole at the middle lower part is provided with a notch in the circumferential direction, and the aperture of a local unthreaded hole formed by the circumferential notch is larger than the maximum thread aperture of the internal thread hole.
2. The quick nut as set forth in claim 1 wherein: the circumferential notches are symmetrically arranged along the circumference of the hole wall of the threaded hole, and the circumferential angles of the two circumferential notches are larger than 90 degrees.
