[0021] As Figures 1 to 7 shown, a stainless-steel anti-loosening fastening block includes a nut main body structure 1 with a regular hexagon cross-section. The central axis position of the nut main body structure 1 is a fastening combined connection hole, which is the fastening hole of the nut structure. A horizontal main body anti-loosening limit plate 2 is provided at the upper end of the nut main body structure 1. A fastening and stabilizing combined frame 3 that passes through the fastening combined connection hole and is symmetrically distributed left and right is provided at the lower end of the main body anti-loosening limit plate 2. The fastening and stabilizing combined frame 3 is an L-shaped structure with the direction facing the outer sides in the left and right directions and is used in cooperation with an open-screw-like structure during use. This structure cooperates with the open slot of the open screw. The upper and lower end faces of the nut main body structure 1 are located between the fastening and stabilizing combined frame 3 and the main body anti-loosening limit plate 2, and the nut main body structure 1 can rotate freely between them. An integrally formed associated combined connection seat 4 is provided at the upper end of the main body anti-loosening limit plate 2 and can be used in cooperation with the associated fastening and anti-loosening structure of the mechanical component during use. A sliding fit connection groove 5 that opens upward and completely penetrates the left and right length directions of the associated combined connection seat 4 is provided at the upper end of the associated combined connection seat 4. Inverted conical combined stop and stabilizing columns 6 are respectively provided at the lower end of the main body anti-loosening limit plate 2 on the left and right sides of the nut main body structure 1, with higher precision during fastening and better fastening fit. A set of symmetrically arranged sliding fit connection columns 7 with a semi-circular cross-section are respectively provided on both sides in the width direction of the associated combined connection seat 4 and can be used in cooperation with a slide rail-like structure. During later use, the overall fastened structure can be moved and fitted through this position. The upper ends of the sliding fit connection columns 7 are on the same plane as the upper end face of the main body anti-loosening limit plate 2, ensuring better strength and flatness of this structure. An avoidance fit groove is provided at the position where the sliding fit connection column 7 intersects with the projection direction of the fastening combined connection hole to avoid affecting the fastening fit at the central position. By integrating the limit structure with the nut and setting combined stop and stabilizing columns on the limit structure, the overall stability during installation and fitting is better, the combined precision during fitting is higher, and at the top position, by setting a sliding fit connection groove and sliding fit connection columns, it can be combined with slide rails of different specifications in an interleaved manner. During the overall movement of the combined position in the later stage, smooth movement and fitting can be achieved, and the fitting strength during fastening can be realized, making the connection stability during use more reliable.
[0022] Preferably, the length of the associated combined connecting seat 4 is greater than the diameter length of the fastening combined connecting hole, so that the overall structural support strength is better and the service life during use is longer.
[0023] Preferably, the width of the associated combined connecting seat 4 is the same as the width of the main body anti-loosening limiting plate 2, ensuring better flatness of the upper structure, more stable structural strength during use, and also being more convenient during production and processing.
[0024] Preferably, the cross-section of the sliding fit connecting groove 5 is a semi-circular structure, and the width of the sliding fit connecting groove 5 is greater than half of the width of the associated combined connecting seat 4, making this structure more convenient during production and processing, having a larger combined space during fitting, and better fitting stability.
[0025] Preferably, the combined stop stabilizing column 6 is connected to the main body anti-loosening limiting plate 2 by riveting, and the cost during production and processing is lower.
[0026] Preferably, the outer end face in the length direction of the sliding fit connecting column 7 coincides with the end face at the corresponding position on the outer side of the main body anti-loosening limiting plate 2, making the flatness of the structure at the outer position better and the structural strength higher.
[0027] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements or replacements can be made, and these improvements or replacements should also be regarded as the protection scope of the present invention.
