Dual-drive control invisible connecting device

Abstract

A dual-drive control invisible connecting device comprises a primary driving body, a secondary driving body, a primary mounting and driving mechanism and a secondary mounting and driving mechanism. Afirst connected body and a second connected body are invisibly connected by the aid of the primary driving body and the secondary driving body, the primary mounting and driving mechanism is used for driving the first connected body, the secondary mounting and driving mechanism is used for driving the secondary connected body, a primary driving body outer thread and a primary driving body inner thread are arranged at one end of the primary driving body, the other end of the primary driving body is provided with a primary driving body mounting groove, a primary driving body connecting outer circle and a primary driving body connecting channel, a primary driving magnet and a primary driving body inner ring end surface are arranged in the primary driving body, the primary driving body inner ring end surface contacts with a connecting bolt, periphery, the periphery of the secondary driving body is provided with a secondary outer thread and a secondary driving body mounting groove, the primary mounting and driving mechanism is driven forwards, the secondary mounting and driving mechanism is driven backwards, and the connected bodies are invisibly connected. When the primary mounting anddriving mechanism is driven backwards, the secondary mounting and driving mechanism is driven forwards, the connected bodies are separated, integrated original product design is ensured, and connectedperfection of a plurality of components is ensured.

Description

technical field [0001] The invention relates to the technical field of fastener connection, in particular to a dual-drive control invisible connection device. Background technique [0002] Fasteners such as screws and bolts are widely used in various types of equipment, and have formed a complete series of standards and become common parts in the industry; It is exposed to the outside, which is convenient for working tools to disassemble and disassemble, which leads to a lot of fasteners being operated outside the connected parts. In order to avoid interference with such fastened parts, it is necessary to process corresponding process bottom holes on the connected parts , especially in the field of large wooden, rubber, plastic and aluminum parts, the traditional fastening connection method is not only cumbersome to operate but also affects the appearance; therefore, a new fastening connection operation method is needed, which can solve the problem of many large components w...

Problems solved by technology

[0002]Screws, bolts and other fasteners are widely used in various types of equipment, and have formed a complete series of standards and become general-purpose parts in the industry; but such fasteners Restricted by the way of operation, some fasteners need to be exposed by the working part to facilitate the disassembly and assembly of the working tools, which leads to the protruding of many fasteners being worked on the outside of the connected parts. In order to avoid interference with such Fasteners need to process corresponding process bottom holes on the connected parts, especially in the field of large wooden, rubber-plastic and aluminum parts. The traditional fastening connection method is not only cumbersome to operate but also affects the appearance; therefore, a new type of The fastening connection operation method can not only solve the seamless fastening of many large components, but also facilitate disassembly and assembly without affecting the appearance, so as to ensure the integrity of the original product design and the perfection of multi-part connection
