Description

The novel electronic scale

Technical field

The utility model belongs to a kind of electronic scale, specifically is a kind of novel electronic scale.

Background technology

Along with the raising of people's living standard, the scale that was used in industrial circle is originally used more extensive in present daily life.Except the scale of weighing in the dealing goods, the weighing scale that uses in health care has added some function exactly on the basis of electronic type weighing scale, can be to the favourable better description of human health status.

The initial scale of using in daily life is exactly a kind of mechanical type spring balance of being convenient to weigh, because the precision of spring balance has only about 1/100 usually, error is bigger, so electronic scales had just been arranged afterwards.Early stage electronic scales disposes lever-type scale structure by a LOAD CELLS and adds that amplifier and display system form, i.e. lever electronic scales, and its precision reaches the scope about 1/800.In order to improve precision, developed 4 electronic scaless that LOAD CELLS is formed afterwards again, though its precision can be brought up to about 1/3000, cost has also increased.

Summary of the invention

In order to solve electronic scales high precision and the low-cost problem that can not get both in the prior art, the utility model on the electronic scales basis of 4 LOAD CELLS the accurate set of scale pan structure and sensor and simplify and form, the precision that had both kept scale, reduced cost again, and can be applied in the health care, increased the scale that measures sb.'s height, can measure people's body weight and height simultaneously, concrete technical scheme is as follows:

A kind of novel electronic scale comprises weighing platform, scale base, LOAD CELLS, control display device; LOAD CELLS has 2 at least, is located between weighing platform and the scale base, evenly distributes; The electric signal output of LOAD CELLS connects the control display device.Described LOAD CELLS is a beam type, two shared supporting surfaces of beam type LOAD CELLS.

Described LOAD CELLS has 4, the corresponding shared supporting surface of two LOAD CELLS.The position of 4 LOAD CELLS and last weighing platform junction is 4 angles of going up weighing platform.

Two load cell structures of the correspondence of a described shared supporting surface are that a strip elastic body is a supporting surface in this elastomeric centre position; Upper and lower sides at elastomeric two ends is respectively equipped with corresponding strain regions.Elastomeric each end promptly is a LOAD CELLS.Principle is, by an end up and down the strain regions of two correspondences respond to elastomeric deformation, this deformation produces electric signal, the control display device is gathered this electric signal, handles obtaining gravimetric value.Upper and lower sides at elastomeric two ends is respectively equipped with corresponding strain regions.

Connect by reinforcement or framework between the elastic body, improve the scale stability of structure.LOAD CELLS loads post with last weighing platform by rubber and is connected.If be applied in the health care, then also comprise height gauge, height gauge is connected with the scale base.

Described scale base can be adjustable scale pin, adjustable scale pin be installed in LOAD CELLS below, LOAD CELLS is supported on the ground.

Described elastic body is a metal material, preferred alloy aluminium or alloy steel.

The utility model passes through unique design, make the LOAD CELLS itself and the scale pan be combined into an integral body, saved the material of scale body, reduced the weighing platform height, four jiaos of unsettled shortcomings of single sensor have also been overcome, because strip metal elastic body length is longer, weight evenly is pressed in the suffered torsion of base that can make scale on the scale base and reduces, and can use thin cast aluminium to do the base of scale.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Example 1

A kind of novel electronic scale comprises weighing platform, scale base, LOAD CELLS, control display device; LOAD CELLS has two groups (4), is located between weighing platform and the scale base, evenly distributes; The electric signal output of LOAD CELLS connects the control display device.Described LOAD CELLS is a beam type, the corresponding shared supporting surface of two beam type LOAD CELLS.The position of two groups of 4 LOAD CELLS and last weighing platform junction is 4 angles of going up weighing platform.LOAD CELLS loads post with last weighing platform by rubber and is connected.

Two load cell structures of the correspondence of described one group of shared supporting surface are, a strip metal elastic body is a supporting surface in this elastomeric centre position, and promptly hold-down support is connected on the scale base by this bearing metallic elastic body; Upper and lower sides at the two ends of metallic elastic body is respectively equipped with corresponding strain regions.Elastomeric each end promptly is a LOAD CELLS.Principle is, by an end up and down the strain regions of two correspondences respond to elastomeric deformation, this deformation produces electric signal, the control display device is gathered this electric signal, handles obtaining gravimetric value.Upper and lower sides at elastomeric two ends is respectively equipped with corresponding strain regions.

The metallic elastic body adopts alloy aluminum or alloy steel

Example 2

On the basis of example 1, between two metallic elastic bodies, be provided with reinforcement and connect, improve the scale stability of structure.

Example 3

On the basis of example 2, also be provided with height gauge, height gauge is connected with the scale base, as the health scale in the health care.

Example 4

On the basis of example 1, between two metallic elastic bodies, be provided with framework and connect, improve the scale stability of structure, electronic scales can be done more, be applied to aspects such as weighbridge, platform balance.
