Auxiliary structure for balauce anti-wind cover

The utility model relates to an auxiliary structure used in scale windproof mantle device, which is characterized in that the structure comprises a roller and a roller mantle and a notch arranged on the back end of the guide rail of the windproof device, wherein the roller is arranged in the notch and the roller mantle is covered thereupon. The roller mantled is provided with a window and the upper end of the roller is exposed from the window of the roller mantle. As the above technical proposal is adopted, sliding is changed into rolling, making the opening operation of the wind mantle door at the left and the right of the scale more simple and smooth and overcoming disadvantageous elements influencing the operational coziness and weighing accuracy, such as blocking and vibrating. The utility model provides a low-cost and effective solution, in which only a few parts are required to add and the parts have low requirement. The auxiliary device of this utility model thoroughly solves the problem that has nagged the user for a long time through the simple physical principle of changing sliding into the rolling, thereby improving accuracy of the scale equipped with windproof mantle and making the weighing operation convenient for the user.
