Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

In the description of the present invention, it should be understood that the terms "central", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., used herein are used in the orientation or positional relationship indicated in the drawings, which are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1, the preferred embodiment of the balance block with an oil blocking function provided by the present invention includes an oil blocking plate 1, a balancing weight 2 and an oil blocking block 3, where the oil blocking plate 1 is a circular ring structure, a through hole 12 for a rotating shaft to pass through is provided on the oil blocking plate 1, the balancing weight 2 is provided on the front surface of the oil blocking plate 1, two oil blocking blocks 3 are provided on the front surface of the oil blocking plate 1 at intervals, the two oil blocking blocks 3 are arranged in a splayed shape with large openings facing outward, a plurality of mounting holes 11 are provided on the oil blocking plate 1 at intervals, and preferably, the cross section of the oil blocking block 3 is kidney-shaped, and the central line thereof is perpendicular to the tangent line of the oil blocking plate 1.
