Description

Electronic platform scale

Technical field

The utility model relates to a kind of electronic weighing device, particularly relates to a kind of electronic platform scale.

Background technology

Electronic platform scale mainly is made up of scale base, scale body, LOAD CELLS, terminal box, signal shielding cable, Displaying Meter etc.Weighing platform adopts steel welding construction, and four jiaos of the scale body are installed in four LOAD CELLS on the scale base by four stressed members respectively, and four LOAD CELLS are aggregated into signal in the terminal box, are transferred to Displaying Meter by terminal box by signal shielding cable again.When weighed object being placed on the scale body, gravitate, gravity affacts LOAD CELLS place on its four jiaos respectively by the scale body, and the elastic body of LOAD CELLS is deformed, and weight signal is transferred to Displaying Meter.But conventional electronic platform scale is mainly used in the object of weighing hundreds of kilogram even several tons of weights, relatively large, the Heavy Weight of volume.For ease of transportation, one or more lifting bolts that are used to transport electronic platform scale are installed on the table top of scale body, after electronic platform scale is in place, remove lifting bolt again, be installed in connecting hole with the bolt plug.Terminal box is to be fixedly mounted in the scale body simultaneously, for ease of wiring, also have the terminal box cover plate on the table top of scale body, after carefully connecting the wire, be connected the terminal box cover plate on the table top again, because scale body table top is not an one-piece construction, so foreign material such as water, earth can enter electronic platform scale inside from the slit of mounting hole in the use, and influences weighing precision.

Summary of the invention

The purpose of this utility model provides a kind of electronic platform scale that can keep measuring accuracy for a long time.

The utility model is that the technical scheme that achieves the above object is: a kind of electronic platform scale, comprise scale base, the scale body, LOAD CELLS, terminal box, and signal shielding cable, described scale body is welded into the framework platform structure by shaped steel, four LOAD CELLS that are connected on the scale body are connected with scale base by web member respectively, it is characterized in that: the fixedly connected rings seat that has internal thread of two sides center of gravity symmetry of described scale body correspondence, the scale body side surface also has notch, terminal box is arranged in the scale body by mount pad, and the detachable side that is connected the scale body of mount pad, on the joint pin of the cable thereto that is connected with each LOAD CELLS, the outer panel that the signal shielding cable that is connected with terminal box passes mount pad connects Displaying Meter.

After the utility model adopts technique scheme, because the lifting bolt center of gravity symmetry that will be used to carry electronic platform scale is installed in two sides of scale body, the mount pad that will be used to simultaneously to install terminal box again is connected the side of scale body, making the terminal box that is fixedly connected in the mount pad is the side-extract type structure, the scale body mesa structure of continuing to use has for many years been done bigger change, owing to cancelled the lifting bolt mounting hole and the terminal box cover plate mounting hole of scale body table top, make whole scale body table top form a complete panel without any the hole, monnolithic case is more attractive in appearance.In addition because of foreign material such as water, earth can not carry out in the scale body from the weighing platform surface, so can keep the measuring accuracy of electronic platform scale for a long time.
