Abstract: A shelving board is used in conjunction with a bracket or rack in a shelving system, for carrying items. The shelving board comprises a board body and a connecting piece. The board body may be a hollow structure or a recessed-and-raised structure, to reduce the material consumption and reduce the cost without affecting the strength. The connecting piece is used to hinder a relative movement between the board body and the rack or between the board body and the bracket, so as to improve the stability of the shelving board. The shelving board may be made by an extrusion process and cut into any length as required. Shelving boards may also be made into prefabricated pieces by an injection molding process, which are spliced into a desired length by means of splicing portions processed on the shelving boards.

Abstract: Some embodiments of the present disclosure provide an adjustable torque clamping fixture, including a clamping body driven by a threaded rod to move and used for clamping an object. The threaded rods implements an axial movement thereof by means of screw thread transmission. An adjustable torque handle is configured at the rear end of the threaded rod. The maximum clamping force is adjusted by the adjustable torque handle. When the maximum clamping force is attained, continued application of a torque on the threaded rod by the handle results in slippage, so that no larger clamping force can be applied, thus implementing precision clamping, and preventing the clamped object from being damaged by an excessive torque. The adjustable torque clamping fixture overcomes the shortcoming of a manual clamping fixture known to inventors of which the magnitude of the clamping force is difficult to determine during use.
