Background

The nut is a part for tightly connecting mechanical equipment, and the nut and the bolt with the same specification can be connected together through the inner thread, for example, the nut of M4-P0.7 can only be connected with the bolt of M4-P0.7 series.

Floating nuts are widely used in the mechanical field, this type of device comprising in particular a support fastened to the structural element at the level of the drilled hole. The support receives a fastening element, such as a nut. The nut may act with the threaded rod to join the structural member to another element. In the prior art, most floating nuts can achieve the high-strength thread fastening effect which is difficult to achieve by common nuts, but when the axis of a screw and the axis of a nut are not in the same line, the centering cannot be accurately and quickly performed, and when a screw and the nut have manufacturing errors, or when the stroke of the screw is too long, or no support exists, the phenomenon of difficult movement is particularly easy to occur; and the floating nut has a limited range of applications and can only be inserted from above the hole.

Chinese patent CN208503389U discloses a floating nut for electric slide rail, and its technical scheme main points are that it has the convex through-hole that is used for passing through the lead screw to open on the nut seat, and nut seat one side is opened flutedly, the degree of depth of recess is greater than the diameter of through-hole, and it has the pit to open on the intermediate junction spare, and the intermediate junction spare joint is equipped with fixture block and cavity on the buffer unit in the recess of nut seat, and the fixture block joint is in the pit of intermediate junction spare, buffer unit and nut seat interference fit, and the nut joint is in the cavity of buffer unit. On the basis of not influencing the screw rod transmission, not only is an intermediate connecting part additionally arranged, but also the noise generated when the nut is rotated and collided is greatly eliminated when the nut is rotated and limited, so that the problems of noise generation and part damage in the prior art are solved.

However, the floating nut as described above is free to slide on the frame during use and is a combination that is difficult to center when the bolt is installed.
