DETAILED DESCRIPTION

[0017] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0018] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0020] like Figure 1As shown, the present application discloses an application of a novel brush holder for a generator slip ring 1, comprising: a generator slip ring 1 and a brush holder and a carbon brush assembly 2, wherein the generator slip ring 1 and the brush holder and the carbon brush assembly 2 slide relative to each other, wherein the front end of the brush holder and the carbon brush assembly 2 is a carbon brush 4 in contact with the generator slip ring 1, and a constant pressure spring 5 is fixed to the rear end screw of the carbon brush 4; the brush holder and the carbon brush assembly 2 comprises two groups of electrically detachable carbon brush boxes 3 arranged upper and lower, and the carbon brush 4 is connected to a brush rod 6; a limiting structure is arranged on the brush rod 6, and a collector ring 14 is arranged at a position close to the carbon brush 4 of the generator slip ring 1.

[0021] like Figure 2 , Figure 3 As shown, the limiting structure includes a limiting bolt 7 connected to the brush rod 6, a first limiting plate 8 is connected between the limiting bolt 7 and the brush rod 6, an elastic column 9 is arranged on the brush rod 6 away from the limiting bolt 7, first air bags 11 are arranged on both sides of the elastic column 9, and a second air bag 10 is arranged on the side of the elastic column 9 away from the brush rod 6.

[0022] Preferably, the pressure of the constant pressure spring 5 is located at the center of the carbon brush 4, so that the brush box is not subjected to stress, achieving the effect of consistent actual pressure and reducing damage to the brush box.

[0023] Preferably, the constant pressure spring 5 is a coil spring type to reduce the problem of frequent replacement due to damage to the laminations.

[0024] Preferably, a mounting frame 13 is provided on the generator slip ring 1 , and the mounting frame 13 is connected to the brush rod 6 .

[0025] Preferably, a limiting rod 12 is provided on the mounting frame 13 for limiting the generator slip ring 1 .

[0026] When the generator slip ring 1 is in use, the relative position of the brush rod 6 and the generator slip ring 1 can be adjusted by setting a limiting structure on the slide rod, and the distance between the carbon brush 4 and the collector ring 14 can be shortened by moving the limiting bolt 7. At the same time, when the limiting bolt 7 moves downward, the first limiting plate 8 squeezes the elastic column 9 downward, and the elastic column 9 undergoes a certain deformation. The first airbag 11 set on the elastic column 9 is squeezed to both sides after being subjected to pressure, so that the first airbag 11 contacts the inside of both sides. At the same time, the second airbag 10 is subjected to downward pressure and squeezed to both sides, and an upward force is generated to fill the gap between the first limiting plate 8 and the elastic column 9. When vibrated, the second airbag 10 can reduce the vibration received by deformation and enhance the stability of the structure, while the first airbag 11 can stabilize the fixation of both sides.

[0027] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
