Embodiments of the present application provide a weighing device that comprises a weighing unit for weighing wafers, a support structure placed on the weighing unit, at least two support platforms disposed on the support structure and each having a bearing surface for supporting peripheral regions of the wafers, and a driving part for driving the support platforms to move on the support structure, so as to adapt the at least two support platforms to bear the differently sized wafers. Since a wafer contacts merely several support platforms, cleanness of the wafer is better maintained during the weighing process; at the same time, the support platforms are enabled to stably bear differently sized wafers through adjustment of movements of the support platforms on the support structure.

The disclosure provides a shopping shelf. The shopping shelf includes: a shelf support; and a rack detachably mounted to the shelf support; where the rack includes: a mounting bracket; a weight sensing device above the mounting bracket; a suspension bracket base above the weight sensing device; and a suspension bracket having one end detachably mounted to the suspension bracket base.

A weighing mechanism (1) includes: a hopper (105) configured to store an article; a hanger (2) on which the hopper is hung; a mass weighing instrument (3) configured to weigh the article stored in the hopper; a connection member (4) that connects the hanger and the mass weighing instrument; a main body member (6) having a through hole (5) through which the connection member penetrates; a diaphragm (7) that connects an outer edge of the connection member and an inner edge of the through hole of the main body member; and a waterproof cover (8) that covers at least part of the through hole between the diaphragm and the hanger. The waterproof cover is detachably attached only to the hanger among the main body member and the hanger.

A scale platform mounting assembly, a scale and a method of assembly. The scale may generally include a housing assembly supportable on a surface; a weight sensor supported in the housing assembly; a platform operable to support an object to be weighed, a force on the platform being applied to the weight sensor; and a mounting assembly to removably connect the platform relative to the housing assembly. The mounting assembly may include a stud supported by one of the housing assembly and the platform, the stud having a ball end, and a mount supported by the other of the housing assembly and the platform, the mount defining a recess having an open end, the ball end of the stud being receivable in the recess through the open end to removably connect the platform.

A shelf bracket assembly mounted upright on a vertically disposed shelf has: a load cell; an anchor; and a cantilever supporting a shelf panel. The cantilever projects from the shelf upright in a substantially horizontal direction. The cantilever has a vertically disposed frame or a vertically disposed metal plate and a mount for the load cell. The load cell has a monolithic measuring body that has: a force-supporting section; a force-introduction section; and a linkage section between the force-supporting section and the force-introduction section. The force-supporting section of the monolithic measuring body is laterally attached to the mount. The monolithic measuring body has at least one mounting hole through which the monolithic measuring body is attached to the mount with a screw extending horizontally through the monolithic measuring body.

An object measurement device for ascertaining measurements of cuboidal and boxed packages to provide measurement data to a host computer is provided. The device may include a frame, a weight sensor, and one or more dimension sensors. The frame may include a base and a vertical support member that extends vertically from the base. The weight sensor may be positioned on the base and may be configured to emit a weight data signal. The dimension sensors may include an upper sensor and one or more side sensors. The upper sensor may be positioned on the vertical support member, and the side sensors may be positioned adjacent to the base. The dimension sensors may be configured to emit dimensional data signals. The host computer may be in communication with the weight and dimension sensors. The host computer may be configured to receive the weight and the dimensional measurement data.
