Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, an electronic platform scale includes a base 1, a scale frame 2 disposed on the base 1, and a platform scale plate 3 disposed on the scale frame 2. The base 1 is surrounded by ribs 4, and the ribs 4 are arranged A cavity is formed inside the base 1, and the scale frame 2 is arranged in the cavity.

[0044] Scale frame 2 comprises upper beam 21, lower beam 22 and load cell 23, upper beam 21 is fixed on the base 1 by bolt, load cell 23 is arranged between upper beam 21 and lower beam 22, upper beam 21 and lower beam 22 is also connected with a shock-absorbing assembly 24, the shock-absorbing assembly 24 includes a shock-absorbing rod 241 whose one end is threadedly connected to the lower beam 22 and the other end is passed through the upper beam 21, and the shock-absorbing rod 241 is sleeved with a shock-absorbing spring 242 ...

Abstract

The invention discloses an electronic platform scale and a weighing method thereof. According to the technical scheme, the electronic platform scale comprises a base, a scale shelf and a platform scale plate, wherein the scale shelf comprises a buffering assembly, a baroceptor, and a control module, the scale shelf makes contact with a top bar earlier that a weighing sensor does, the buffering assembly comprises a supporting casing pipe, a top block which is slidably installed in the supporting casing pipe and abuts against the top bar, the interior of the supporting casing pipe is provided with an inflating body which abuts against the top block, the inflating body is provided with a gas nipple, and the gas nipple is connected to a solenoid valve through an air tube; the baroceptor is used for detecting air pressure in the inflating body and converting the air pressure into an air pressure electric signal through a measuring circuit; the control module is used for receiving the air pressure electric signal and obtaining weight data through operation and conversion. If the weight data is smaller than maximum weighting data of the electronic platform scale, the solenoid valve is controlled to be breakover so that air inside the inflating body can be released, the inflating body is filled with air, which plays a buffering effect, and avoids damages of the weighing sensor caused when the weighing sensor is shocked due to transient contact of the top bar and the weighing sensor.

Description

technical field [0001] The invention relates to weighing equipment, in particular to an electronic platform scale and a weighing method thereof. Background technique [0002] The electronic platform scale is a weighing appliance that uses the force deformation principle of the electronic strain element to output a small analog electrical signal, which is transmitted to the weighing display instrument through the signal cable, for weighing operation and display of the weighing result. [0003] In the currently widely used electronic platform scales, if a heavy object placed on the platform platform will be directly loaded on the load cell, it is easy to cause damage to the load cell; and if the weight of the heavy object exceeds the maximum weighing capacity of the electronic platform scale Correspondingly, the load cell is damaged, which affects the service life of the electronic platform scale and increases the user's use cost. Contents of the invention [0004] In view ...
