[0008] The rotary connection fixing assembly includes two rows of annular grooves on the outer surface of the rotary discharge cylinder. A preset number of balls are rolled and embedded in the annular grooves. A ball positioning component for limiting the balls is provided on the side wall of the rotary discharge cylinder between the two rows of annular grooves. A ball sealing sleeve is rolled and embedded on the side end face of the ball. An upper ball cover plate and a lower ball cover plate are respectively provided on the upper and lower end faces of the ball sealing sleeve. The inner end faces of the upper ball cover plate and the lower ball cover plate are respectively rolled and engaged with the balls in the two rows of annular grooves.

[0009] A fixed discharge cylinder connector is fixedly provided on the lower end face of the ball bearing cover plate, and the fixed discharge cylinder connector is detachably and fixedly connected to the fixed discharge cylinder.

[0010] Furthermore, the rotating quick-clamp connector can be any one of a snap-fit ​​connector, flange, or clamp.

[0011] Furthermore, the ball positioning component is an annular plate fixed to the side wall of the rotating discharge cylinder.

[0012] Furthermore, the ball positioning component and the ball sealing sleeve are fitted with a clearance.

[0013] Furthermore, the fixed discharge cylinder connector can be any one of a snap-fit ​​connector, flange, or clamp.

[0014] Furthermore, the upper ball cover plate, the ball sealing sleeve, and the lower ball cover plate are sequentially inserted and fixed by cover plate fixing bolts.

[0015] Furthermore, the fixed discharge cylinder connector is a flange, the lower end face of the lower ball cover plate is fixed to the flange, the side end face of the lower ball cover plate is clearance-fitted with the rotating discharge cylinder, the lower ball cover plate, the rotating discharge cylinder, the fixed discharge cylinder and the flange form a cavity, and an air source quick connector is provided on the side wall of the rotating discharge cylinder, which is connected to the cavity.

[0017] One advantage of this utility model is that it provides a rotating connection and fixing component, which realizes the rotating connection between the fixed discharge cylinder and the rotating discharge cylinder. The rotating discharge cylinder rotates 360° coaxially with the equipment, while the fixed discharge cylinder is in a stationary state and connected to the receiving equipment. This can avoid the mechanical injury safety hazards caused by the rotating discharge port. The equipment discharge is more stable, does not detach, has a good sealing effect, has low rotational friction, is smoother, and has strong applicability.

[0018] One advantage of this invention is that it provides a rotating connection fixing component, which is easy to disassemble, maintain, and clean.
