Detailed Description
The foregoing and other technical matters, features and effects of the present invention will be apparent from the following detailed description of the embodiments, which is to be read in connection with the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are simply directions with reference to the drawings. Therefore, the directional terminology used is for the purpose of describing, but not limiting, the invention, and moreover, like reference numerals designate like elements throughout the embodiments.
The following describes a specific embodiment of the present embodiment with reference to the drawings.
Fig. 3 is a front view of the present invention, fig. 4 is a top view of the present invention, and fig. 5 is an installation schematic view of a first viewing angle of the present invention. Referring to FIGS. 3, 4 and 5, a nut locker for C-section steel includes a C-section steel 1 and a nut 2 engaged with each other.
The C-section steel 1 comprises a top portion 11, which top portion 11 is provided with two flanges 13 defining a longitudinal groove 12. The C-section steel also includes a bottom portion 14 opposite the top portion 11.
The width of the nut 2 is smaller than the width of the longitudinal groove 12 and the length of the nut 2 is larger than the width of the longitudinal groove 12. The nut 2 includes an upper top surface and a lower bottom surface. The lower bottom surface is opposite the bottom 14. The nut 2 further comprises two short sides and two long sides surrounding the nut 2. The nut 2 is provided with a through hole 21. The upper top surface is provided with two grooves 22 for embedding the longitudinal grooves 12. The height of the through hole 21 of the nut 2 is h1The height of the nut 2 at the position where the groove 22 is formed is h2，h1＞h2. The groove 22 comprises two opposite pressing surfaces. A plurality of engaging protrusions 23 are arranged at the edge of the pressing face. The cross-sectional dimension of the engaging projection 23 is smaller than the width of the groove 22. The pressing surface presses the side of the longitudinal groove 12 to be deformed. The plurality of engaging protrusions 23 are arranged in a staggered manner at equal intervals. In the present embodiment, two engaging protrusions 23 are provided on one side of the groove 22, and three engaging protrusions 23 are provided on the other side of the groove 22. The apex of the engaging projection 23 and the edge of the pressing surface are in a circular-arc transitional connection. The engaging protrusion 23 has a U-shaped cross-sectional shape. The movement track of the flange 13 is S-shaped.
Fig. 6 is an installation schematic of the present invention from a second perspective. As shown in fig. 6, the working principle of the present invention is as follows:
the groove 22 is still a straight groove, but the engaging protrusion 23 is at the side of the groove 22, when the flange 13, i.e., the inside curl of the C-shaped steel 1 enters the groove 22, the moving track of the flange 13 is S-shaped, the flange 13 is deformed by the pressure of the engaging protrusion 23, and the engaging protrusion 23 bites into the side of the flange 13. Further, the bolt passes through the through hole 21 to fasten and connect the nut 2 and the C-shaped steel 1, so as to achieve the anti-skid effect.
