Description

Technical Field

[0001] The utility model relates to a rotary joint, in particular to a universal rotary joint. Background Art

[0002] The rotary joints currently used in the market all use the friction between metals to control the torque of rotation. This structure will cause abnormal noise and a sense of jamming when the product rotates. The longer the product size is, the larger the friction contact area will be, and the torque will vary greatly during the production process. If the torque is too tight, the rotation will not stop, and if the torque is too small, the rotation will not stop. Utility Model Content

[0006] The assembly end of the base is inserted into a through hole provided at one end of the housing and is subjected to riveting processing by a jig;

[0007] The rotating member is provided with a rubber compression structure, and the rubber is compressed by squeezing the rotating member through the linking member.

[0008] As a preferred technical solution, the rubber compression structure includes a first rubber ring and a second rubber ring; a first mounting groove and a second mounting groove for assembling the first rubber ring and the second rubber ring are respectively provided at both ends of the rotating member; the first rubber ring and the second rubber ring are compressed by squeezing the rotating member through the link member, thereby controlling the rotational torque.

[0009] As a preferred technical solution, a U-shaped groove is provided at the end of the rotating member, and a swing arm connecting the pull rod and the glue stick is assembled through the U-shaped groove.

[0010] As a preferred technical solution, a hole is opened at one end of the base for assembling the machine equipment end; a riveted end is formed at the other end of the base, and the riveted end of the base is riveted into the through hole at the other end of the shell by a jig.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model is different from the existing metal-to-metal contact rotary joint. The utility model adopts a rubber ring to control the torque, which greatly reduces the abnormal noise and jamming during the rotation process and improves the user experience.
