Embodiment Construction

[0026] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0027] Such as Figure 4 As shown, the connector of the present invention includes a connecting outer sleeve and a connecting inner sleeve, the connecting inner sleeve is inserted into the connecting inner sleeve and the locking structure of the locking structure can make the connecting inner sleeve and the connecting outer sleeve rotate with each other, and The connecting inner cover and the connecting outer cover cannot fall off each other.

[0028] The key point of the present invention lies in the ingenious setting. The grooves of the connecting sleeve have circular arcs with different radii, and the resistance is controlled by the size of the circular arcs, so that the resistance of the connector is small when it is screwed together, which is convenient for installation and operation. T...

Abstract

The invention discloses an anti-loosening and anti-rotation structure for threaded connection. The structure comprises a connecting outer sleeve, a connecting inner sleeve and anti-rotation reeds, wherein an inner surface of one end of the connecting outer sleeve is provided with a number of grooves that are arranged on the same circumference, the grooves are the same in structure, and each groove is provided with three arcs that are different in radius; along a clockwise screw thread engagement direction, a first arc is far greater than a third arc in radius; an outer surface of the connecting inner sleeve is provided with a number of gaps that are arranged on the same circumference, an inner part of each gap is provided with an anti-rotation reed, and each anti-rotation reed corresponds to a groove on the inner surface of the connecting outer sleeve; when a connector plug head is plugged in a plug seat, easy rotation can be realized in the presence of resistance due to a large radius of the first arc in each groove of the connecting inner sleeve and a smooth chamfer; after the plug head is screwed, great resistance of the anti-rotation reeds is met when a product operates in a vibration environment due to a small radius of the second arc in each groove of the connecting inner sleeve, and therefore a connector can be prevented from loosening and can be protected.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a screw connection anti-loosening and anti-rotation structure. Background technique [0002] Following the British Industrial Revolution in the 18th century, machinery manufacturing has crossed the century and become one of the most mature industries. However, even with the manufacturing pronoun of Made in Germany, machinery manufacturing is still moving forward, and excellence is the source of progress. [0003] Threaded connection is the most common connection method in the machinery industry, and thread loosening has naturally become one of the key points that every designer must consider. Now common thread locking has the following forms: parallel nuts, thread fastening glue, Tightening screws, anti-rotation springs, etc. [0004] According to different use environments and product structure sizes, the anti-loosening forms adopted are also different, but there are more or less prob...
