The existing current collectors have the following disadvantages: 1) the sliding block and the sliding contact line slide and rub for a long time, so that serious abrasion is caused, a groove is formed, and the reliability of electric connection and the service life of a current collector are influenced; 2) the trolley line is often tightly pressed on the sliding block, and during the movement, the current collector is installed on the moving equipment without any buffer amount, and the trolley line can be separated from the sliding block when the current collector jolts or shakes.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a power receiver that reduces wear, does not form a groove, and affects the reliability of electrical connection and the service life of the power receiver.

In order to solve the technical problem, the utility model discloses a technical scheme as follows: a current collector is characterized by comprising a current collector protective cover, a hanging screw, a top cover, an upper cover plate, a lower cover plate, a rotating shaft and a brushless motor, wherein the top cover is a circular plate type, the lower cover plate is a hollow step circular plate, threading holes and screw holes are symmetrically formed in four corners of the lower cover 4, the screw holes are matched with the hanging screw, the top cover and the lower cover plate fixedly clamp the current collector protective cover through the hanging screw, and the lower cover plate is fixedly provided with the brushless motor, a brushless motor adjuster and a plurality of wiring terminals; the upper cover plate is a hollow circular plate, a plurality of binding posts are arranged on the upper cover plate, the rotating shaft penetrates through the upper cover plate, the lower cover plate and the center shaft of the brushless motor, the rotating shaft is fixedly connected with the upper cover plate through a fixed threading ring and is rotatably connected with the lower cover plate through a bearing and fixedly connected with a rotor of the brushless motor, and the rotor of the brushless motor drives the rotating shaft to rotate when the brushless motor is electrified.

Furthermore, the rotating shaft is a hollow stainless steel pipe, so that the weight is reduced, and the rotation becomes more convenient.

Furthermore, the top cover is provided with a groove, so that the top end of the protective cover of the current collector is embedded into the groove.

Further, a rubber ring is arranged in the groove. The rubber ring is utilized to make the current collector cylinder more stable, and the sealing performance is improved.

Therefore, compared with the prior art, the utility model has the following advantages:

1) the utility model discloses a brushless motor cancels original carbon brush, does not have the wearing and tearing of slider and wiping line, and operating duration is long, difficult hair scald, longe-lived.

2) The utility model discloses be equipped with the recess on the top cap, be equipped with the rubber circle in the recess, make the current collector barrel more firm, improved the leakproofness.
