Reinforced quick nut

Abstract

This application relates to the field of vibration testing workpieces, and specifically provides a reinforced quick nut, which includes a nut body. The nut body has a first surface and a second surface that are oppositely arranged. Inside the nut body, there is a screw hole that penetrates through the first surface and the second surface, and the inner wall of the screw hole has threads. The screw hole includes a straight hole and an inclined hole that partially overlaps with the straight hole. The straight hole has a first central axis, and the inclined hole has a second central axis. The first central axis is arranged perpendicular to the first surface, and the second central axis is inclined with respect to the first central axis. In the direction of the first central axis, the height of the straight hole is greater than

Claims

1. A reinforced quick-release nut, comprising: The nut body has a first surface and a second surface arranged opposite to each other. The nut body has a threaded hole penetrating both the first and second surfaces. The inner wall of the threaded hole has threads. The threaded hole includes a straight hole and an oblique hole partially overlapping the straight hole. The straight hole has a first central axis, and the oblique hole has a second central axis. The first central axis is perpendicular to the first surface, and the second central axis is inclined to the first central axis. Along the direction of the first central axis, the height of the straight hole is greater than 30 mm. Multiple stripes are spaced apart within the oblique hole. These stripes are parallel and spaced apart, extending at intervals along the direction of the second central axis. The end of each stripe smoothly connects to a thread tooth of the thread.

2. The reinforced quick-release nut as described in claim 1, wherein, The thread is provided on the inner wall of the straight hole, and the thread pitch is 1.6 to 2.0 mm.

3. The reinforced quick-release nut as described in claim 1, wherein, The angle between the first central axis and the second central axis is 12° to 15°.

4. The reinforced quick-release nut as described in claim 3, wherein, The angle between the first central axis and the second central axis is 13.5°.

5. The reinforced quick-release nut as described in claim 1, wherein, The inner diameter of the oblique hole is 18 mm to 22 mm, and the inner diameter of the straight hole is 12 mm to 16 mm.

6. The reinforced quick-release nut as described in claim 1, wherein, The reinforced quick-release nut also includes a base, which includes an outer sleeve and a connecting part. The outer sleeve is fitted onto the outside of the connecting part, and the connecting part is provided with a through hole. The nut body passes through the through hole.

7. The reinforced quick-release nut as described in claim 6, wherein, The outer sleeve has multiple anti-slip grooves on the side surface opposite to the nut body, and the extending direction of the anti-slip grooves is parallel to the first central axis.

8. The reinforced quick-release nut as described in claim 6, wherein, The first surface protrudes from the outer cover portion, and the second surface is located inside the outer cover portion.

9. The reinforced quick-release nut as described in claim 8, wherein, The nut body has two notches at one end near the first surface, and the two notches are symmetrically arranged.

10. The reinforced quick-release nut as described in claim 1, wherein, The reinforced quick-release nut is made of bearing steel.
