Product overview

Rotating fasteners are fasteners used for connecting parallel or diagonal rods. Scissors diagonal rods shall be fixed on the protruding end or vertical rod of intersecting transverse horizontal rods with rotating fasteners. The distance from the center line of rotating fasteners to the main node shall not be greater than 150mm. Both ends of the in-line and open double-row scaffolds shall be provided with transverse diagonal braces, and one in the middle shall be provided every 6 spans. The longitudinal lap length shall not be less than 1 m, and 3 rotating fasteners shall be arranged at equal intervals for fixation. The distance from the edge of the cover plate of the end fastener to the end of the lap longitudinal horizontal rod shall not be less than 100mm. Weight of rotating fastener: press scissors to support one for each fastener point, 14.6N/piece.

The main function of the rotating fastener is to connect and fix the two components and can rotate flexibly, which is convenient for construction. Fasteners generally refer to the intermediate connecting parts connecting two components, which are mostly used to fix steel pipe feet with an outer diameter of Φ48mm in construction projects.

Performance characteristics

1. The friction coefficient of the rotating fastener is smaller than that of the sliding fastener, and the transmission efficiency is high. Under normal circumstances, the friction coefficient of the rotating fastener is 0.001-0.005, while the friction coefficient of the sliding fastener reaches 0.08-0.12.

2. The production of rotating fasteners has achieved standardization, serialization and universal production, which is suitable for mass production and supply, and is extremely convenient for use and maintenance.

3. It is made of fastener steel and has undergone heat treatment technology. Therefore, the rotary fastener not only has good mechanical properties and service life, but also can save the cost of non-ferrous metals required for the manufacture of sliding fasteners.

4. The internal clearance of the rotating fastener is very small, the machining accuracy of all parts is very high, and the accuracy of operation is also high. In addition, the rigidity of the fastener can be enhanced by the preload method, which is very important for precision machinery.

5, there are some rotating fasteners can bear radial load and axial load at the same time, so that you can simplify the structure of the fastener support.

6. The transmission efficiency of the rotating fastener is high. Less heat, can reduce the consumption of lubricating oil, maintenance work is very simple.

7. The rotary fastener can be conveniently applied to any axis in space.
