Title:

NOVEL SCREW NUT PAIR

Document Type and Number:

WIPO Patent Application WO/2021/139460

Kind Code:

A1

Abstract:

A novel screw nut pair, comprising a guide rail (1) and round holes (2); the round holes (2) are provided at the top and bottom of a front end surface of the guide rail (1), the guide rail (1) comprises a power device (3); the power device (3) comprises a first square block (301), a motor (302), a rotating shaft (303), a first bearing (304) and a first bevel gear (305); the rotating shaft (303) is driven to rotate by means of an output shaft of the motor (302), the rotating shaft (303) drives the first bevel gear (305) to rotate, the first bevel gear (305) drives a second bevel gear (404) to rotate, and the second bevel gear (404) drives a threaded rod (402) to rotate, so that the threaded rod (402) drives, by means of balls (406), nut bases (405) to rotate, the nut bases (405) drive sliding blocks (407) to rotate, and at the same time, the left and right nut bases (405) clamp a spacer (409) tightly, solving the problem that a gap may be generated when an individual screw nut operates for a long time. In addition, a handle (509) drives a long rod (507) to move, so that the long rod (507) drives first connecting rods (505) and second connecting rods (508) to move, the first connecting rods (505) drive concave rods (503) to move, and at the same time, the concave rods (503) are fixed by means of a second bolt (504), solving the problem that there is merely a single method to fix a nut.
