Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of slip ring especially relates to a via slip ring structure based on 360 degree rotation. BACKGROUND

[0002] Via type conductive slip ring is the general term of a series of conductive slip rings with holes in the center, which can be applied to the mixed transmission of power, control and digital signals with 360 degree unlimited rotation, and is commonly used in high-end industrial electrical equipment or precision electronic equipment with multi-function, high performance, high precision and multi-element continuous rotation. It has low contact pressure, is maintenance-free, does not require lubricating oil, has low noise and low contact wear, and is usually applied to wind power generation, military equipment, revolving doors and industrial robots.

[0003] In the use of the above technology, it is found that the existing via type conductive slip ring has the following technical problems in fixing the rotating shaft and the rotor part: four tightening screws are usually used to fix the rotating shaft by friction, which inevitably causes scratches on the rotating shaft, and each time the tightening screws need to be tightened or loosened, the process is relatively complicated. Therefore, we design a via slip ring structure based on 360 degree rotation to provide another technical solution for the above technical problems. UTILITY MODEL CONTENTS

[0004] Therefore, it is necessary to provide a via slip ring structure based on 360 degree rotation, which places the rotor outside the rotating shaft and the limiting rod, and the limiting rod effectively limits the outer ring shell. Then, the rotating shaft drives the rotor to rotate, and the rotor and the outer ring shell rotate, so that the outer ring conductor on the outside of the rotor is electrically connected with the outer ring conductor on the outside of the outer ring shell, thereby improving the practicality and convenience of the device. When the rotating shaft drives the rotor to rotate, the high speed causes the rotating shaft and the rotor to idle. At this time, the arc-shaped limiting plate drives the anti-skid pad to extrude and lock the rotating shaft, so that the arc-shaped limiting plate drives the U-shaped ring shell and the rotor to rotate stably and quickly.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0007] As a preferred implementation form of the through-hole slip ring structure based on 360-degree rotation provided by the utility model, one end of each of the two arc-shaped limiting plates close to each other is fixed with an antiskid pad.

[0008] As a preferred implementation form of the through-hole slip ring structure based on 360-degree rotation provided by the utility model, the top end and the bottom end inside the U-shaped ring shell are both slidingly connected with extrusion rods, one end of each of the two extrusion rods away from each other is fixed with a top block, and one end of each of the two extrusion rods close to each other is fixed with an arc-shaped limiting plate.

[0009] As a preferred implementation form of the through-hole slip ring structure based on 360-degree rotation provided by the utility model, the inside of the U-shaped ring shell is rotationally connected with a rotating ring, the top end and the bottom end inside the rotating ring are both fixed with slope blocks, and one end of each of the two slope blocks close to each other is slidingly connected with a top block.

[0010] As a preferred implementation form of the through-hole slip ring structure based on 360-degree rotation provided by the utility model, the top end of one end of the U-shaped ring shell is rotationally connected with a clamping block, the outside of the rotating ring is fixed with a plurality of limiting blocks, and the bottom end of the clamping block is slidingly connected with a limiting block.

[0011] As a preferred implementation form of the through-hole slip ring structure based on 360-degree rotation provided by the utility model, the outer ring shell body and the rotor are respectively provided with outer ring conductive wires.

[0012] It can be seen without doubt that the above technical solutions of the application can certainly solve the technical problems to be solved by the application.

[0013] Meanwhile, through the above technical solutions, the utility model at least has the following beneficial effects:
