Today’s Patent – Mechanical Structure for Telescopic Rotating by a Helical Elastic Part

The said invention (US11982338B1) was invented by Jia He, and patented by USPTO on October 27^th, 2023. Currently, it stands assigned to the Individual.

This mechanical structure uses a helical elastic part to enable simultaneous telescoping and rotation, eliminating the need for complex motors or gear assemblies. The structure includes a main body with an internal cavity, where a helical elastic part, embedded in a soft rubber flexible cavity, drives the rotation of an external object while allowing it to telescope. A locking part secures one end of the internal cavity, with a bottom cover outside it, and a rotating sleeve at the entrance on the other end. The housing of the cavity, connected to both the rotating sleeve and locking part, allows the structure to achieve dual movements—telescoping and rotation—without electric assistance. This design simplifies assembly and maintenance, meeting demands for a range of applications, such as mechanical processing, massage devices, and transmission systems.

The design incorporates several enhancements for ease of use and durability. For instance, friction-reducing balls are integrated into the rotating sleeve to aid rotation within the housing, and grooves in the housing’s inner wall support smooth ball movement. Other features, like a rotary locking ring and a snap-sealing cap, secure the structure’s entrance, while an external sleeve over the bottom cover provides a grip for handling. The helical elastic part can consist of a single or dual-line winding, with plastic options available for added flexibility. This structure offers a compact, straightforward solution for achieving telescoping rotation in various mechanical applications.
