High-stability special-shaped double-screw assembly for mechanical configuration

Abstract

The invention discloses a high-stability special-shaped double-screw assembly for mechanical configuration. The high-stability special-shaped double-screw assembly comprises a polygonal barrel, wherein the cross section of a first T-shaped rotating block is circular, the bottom surface of the first T-shaped rotating block is fixedly connected with the top surface of a disc, a dovetail groove is annularly formed in the inner top surface of the polygonal barrel, the bottom surface of a second T-shaped rotating block is attached to the top surfaces of screws, second sealing rings are rotationally arranged on the screws in an attached mode, the second sealing rings are fixedly embedded into the top surface of the disc through glue, the bottom surfaces of gear rings are attached to the inner bottom surface of the polygonal barrel, an inner gear ring is fixedly connected to the inner side wall of the polygonal barrel, the inner gear ring is meshed with the two gear rings respectively, a sleeve is fixedly arranged on the first T-shaped rotating block in a sleeving mode, a barrel body is made of an alloy steel material, and the wall thickness of the disc is 3 mm-5 mm. The two screws can be limited and restricted with each other, meanwhile, the inner gear ring can be braked, so that the polygonal barrel is effectively prevented from rotating and loosening, the safety performance of equipment is improved, the safety coefficient is indirectly improved, and the use requirements are met.

Description

technical field [0001] The invention relates to the technical field of mechanical configuration, in particular to a special-shaped double screw assembly with strong stability for mechanical configuration. Background technique [0002] Screw: A type of fastener consisting of a head and a screw rod. It can be divided into three types according to its use - machine screws, set screws, and special-purpose screws. It can directly fix equipment. Screw connections are detachable. Connection, screws are widely used in mechanical configuration. Traditional screws are small in size. When the screws are used to fix the device, it takes time and effort to screw in multiple screws in sequence. A little carelessness when screwing in the device at the beginning will easily make the screws crooked. Moreover, due to external influences during long-term use, loosening or falling off occurs, resulting in failure of the screw connection, which has potential safety hazards and cannot meet the us...

[0002] Screw: A type of fastener consisting of a head and a screw rod. It can be divided into three types according to its use - machine screws, set screws, and special-purpose screws, which can directly fix equipment. Screw connections are detachable. Connection, screws are widely used in mechanical configuration. Traditional screws are small in size. When the screws are used to fix the device, it takes time and effort to screw in multiple screws in sequence. A little carelessness when screwing in the device at the beginning will easily make the screws crooked. And during long-term use, due to external influences, loosening or falling off occurs, resulting in failure of the screw connection, posing a safety hazard, and cannot meet the needs of use
