Multi-friction plate anti-loosening bracket joint device

Abstract

The invention discloses an anti-loosening bracket joint device with multiple friction plates. The anti-loosening bracket joint device comprises a rotary base, an adapter crankshaft, an adapter block, a locking bolt, a locking cover, a first friction plate, a rotary shaft, a second friction plate (number of friction plates can be increased), a rotary head rotation block and a hanging plate assembly, wherein the rotary base is fixedly arranged on parts such as a desktop and a wall through connection or other joints; the adapter crankshaft, the rotary base and the adapter block form a rotary pair; the locking cover is blocked with the rotary head rotation block through the locking bolt; the rotary shaft penetrates through the center of the first friction plate, the center of the second friction plate and the center of a square hole bearing, and is positioned in a cavity which is formed by fixedly connecting the locking cover and the rotary head rotation block; and the rotary head rotation block is connected with the hanging plate assembly through a blocking pin. According to the anti-loosening bracket joint device disclosed by the invention, multiple friction plates are adopted, so that friction surfaces and axial pressing are increased, and therefore, greater friction force can be obtained. The anti-loosening bracket joint device is reasonable in design, is simple in structure, and is suitable for the optimized design of the anti-loosening bracket joint device.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, in particular to an anti-loosening bracket joint device with a plurality of friction plates. Background technique [0002] With the improvement of living standards, people have increasingly higher requirements on the convenience of use and adjustment of monitors, all-in-one computers, televisions and other equipment in terms of office, leisure and entertainment. The mechanical arm structure has the advantages of large adjustment range and convenient conditions, and has been increasingly widely used. However, the joints of the robotic arm are prone to loosening after repeated adjustments; when supporting large-scale display devices, larger joints are often required to achieve reliable support without slipping. For this reason, this patent realizes the effective improvement of the joint supporting capacity and the relaxation of the slipping phenomenon by including multiple friction plate...
