[ detailed description ] embodiments

The directional terms of the present invention, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", etc., are only directions in the drawings, and are only used to explain and illustrate the present invention, but not to limit the scope of the present invention.

Referring to fig. 1, a composition structure of the weight deviation meter of the invention is shown, the weight deviation meter is an integrated machine with a cabinet body structure, and comprises a cabinet body and a measuring unit installed in the cabinet body, wherein the cabinet body comprises a plurality of metal bracket substrates and a metal skin, the cabinet body is divided into two parts at intervals, the lower half part is a tool box 1, and the upper half part is used for installing a measuring unit 2 and a control panel 3.

Wherein the measuring unit 2 has a steering door mechanism 4 directly in front of it, as shown in fig. 2 and 3, giving a schematic view of the steering door mechanism. The steering door mechanism 4 comprises a longitudinal linear rail 401 and a transverse linear rail 402, the two linear rails are both mounted on the cabinet body, and the two linear rails are perpendicular to each other. The sliding blocks 403 are installed below the two linear rails, the sliding blocks 403 can slide along the linear rails, the tail ends of the two sliding blocks are rotatably connected with a door panel 405 through bearings 404, two steel ball guide wheels 406 are installed at the bottom of the door panel 405, and two U-shaped limiting guide rails 407 which are perpendicular to each other are installed below the steel ball guide wheels, so that the steel ball guide wheels 406 can slide in the U-shaped limiting guide rails 407. During the door plant switch, the slider 403 of door plant top moves along the line rail, and steel ball leading wheel 406 of door plant below moves along U type limit guide 407, makes the door plant do the tangent motion to realize 90 degrees and turn to, prevent to collide the door plant when the during operation of opening the door, the staff of being convenient for operates.
