The invention discloses a fast connecting and fastening device and a fastening and releasing method thereof and relates to the field of fastening devices. The device comprises rod parts, a hinge part,a pre-tightening spring, a thread cylinder, a thread column, a resetting spring, a wedge block, a locking spring and a locking shaft. A main body of the thread cylinder is a columnar cylinder, and the inner wall is provided with threads distributed at intervals in the peripheral direction. A main body of the thread column is a cylinder, the lower middle portion is provided with a boss, and threads are distributed on the boss at intervals in the peripheral direction. The upper portion of the hinge part is a cylinder provided with a round boss, and the lower portion is a hollow-out structure body provided with three pin shafts which are distributed uniformly in the peripheral direction. The three rod parts are rectangular variable section rods. The locking shaft is a cylinder with large andsmall variable diameters. The wedge block is a rectangular plate with one end provided with an oblique edge. According to the fast connecting and fastening device, parts can be connected, fastened and released fast and effectively, limitation of operation space is small, and the device can be operated by one person.
Description
technical field [0001] The invention relates to the field of fastening devices, in particular to a quick connection fastening device, a fastening method and a release method thereof. Background technique [0002] When connecting parts with through holes, bolts and nuts are used for connection and fixation. [0003] Ordinary fasteners can meet the general use occasions, but they require high operating space during use, usually require the cooperation of multiple people, and the operating efficiency is low. For special occasions where the space is limited and the environment is harsh, or when multiple people are inconvenient to cooperate and a single person cannot complete the operation, ordinary fasteners cannot meet the needs of use. Contents of the invention [0004] Aiming at the above problems and technical requirements, the present invention proposes a quick connection fastening device, a fastening method and a release method thereof. [0005] Technical scheme of the...
