Detailed Description
As shown in fig. 1 and 2, the butterfly nut includes a nut main body 01, a first threaded hole 22 is formed in the center of the nut main body 01, butterfly wings 02 are arranged on two sides of the nut main body, a locking hole 23 is formed in the top ends of the butterfly wings 02, and the locking hole 23 extends to the first threaded hole 22 perpendicular to the upper surface of the butterfly wings 02. When the nut body 01 is installed on the bolt, the locking screw is installed in the locking hole 23 and extends to the first threaded hole 22 along the locking hole 23, so that the locking screw is clamped on the bolt to achieve the locking effect; the direction and the threaded hole of traditional locking hole 23 are perpendicular for installation required space is great when the installation, and installation difficulty in the installation environment such as counter bore, buried hole, locking screw also drops easily, and the utility model discloses a direction and the axial lead of first screw hole 22 of locking hole 23 are 30 ~ 60, consequently for traditional locking screw's mounting means, the utility model discloses required installation space is littleer when installing locking screw, and locking screw is difficult to drop during the installation for the integral erection mode is more convenient.
The locking hole 23 is a common hole 231 at one end close to the upper surface of the butterfly wing 02, a second threaded hole 232 at one end close to the first threaded hole 22, and the diameter of the common hole 231 is larger than that of the second threaded hole 232. Locking hole 23 comprises ordinary hole 231 and second screw hole 232, and locking screw places in locking hole 23 through the ordinary hole 231 of great aperture during the installation, thereby avoids locking screw to drop when the installation and reduces the installation degree of difficulty, and locking screw reaches the effect of locking through the fixed of second screw hole 232, and overall structure is simple and simple to operate.
A positioning chamfer 233 is arranged between the common hole 231 and the second threaded hole 232. The aperture ratio screw thread aperture of ordinary hole 231 is big, reaches the location effect through location chamfer 233 when locking screw passes ordinary hole 231, avoids being difficult to aim at the problem at the screw thread center when being connected with second screw hole 232, reduces the installation degree of difficulty, and overall structure is simple and processing is convenient.
