Abstract

The utility model relates to a multifunctional convenient scale, comprising a scale pan 1, a scale beam 2, and a digital weight display 6. The left end of the scale beam 2 is fixedly connected with the scale pan 1, and the right end of the scale beam 2 is inserted into a casing 3. The scale beam 2 is supported on a round ball 17, the right end of the scale beam 2 is connected with a sensing device 19 through an adjusting screw 15, a calculator 4 and the digital weight display 6 are arranged on the casing 3, a hollow handle 10 is fixedly connected with the casing 3, an electric cell 9 is arranged in the hollow handle 10, and a switch 11 is arranged on the handle. When the utility model is used, weight can be displayed by the digital display through using one hand to spade objects to the scale pan, and the price can be calculated by the calculator positioned on the casing. The utility model has the advantages of flexible operation and convenient use.

Description

Portable convenient scale

The utility model relates to weighing uses weighing apparatus, specifically is a kind of multi-functional nimble scale.

Scale is indispensable a kind of metering outfit in industrial and agricultural production, commodity circulation and the daily life.Scale of a great variety has steelyard, platform scale, electronic scales or the like.But existing scale function singleness, using of having is very not convenient yet.

The purpose of this utility model provides a kind of flexible operation, convenience, has the multi-functional nimble scale that numeral shows and have counter.

The utility model is achieved in that multi-functional nimble scale comprises the scale pan 1, the arm beam of steelyard 2, digital weight display 6.It also has housing 3, handgrip 10, counter 4 in addition.The left end of the arm beam of steelyard 2 and the scale pan 1 are connected, and right-hand member inserts in the housing 3 by the long and narrow vertical core 16 on housing 3 left sides.The arm beam of steelyard 2 is bearing on the pole 18 by ball 17, and pole 18 is connected with housing 3.The right-hand member of the arm beam of steelyard 2 links to each other with sensing device 19 by adjusting screw 15.Counter 4, digital weight display 6 be installed in housing 3 above.The handgrip 10 and the housing 3 of hollow are connected.Battery 9 as power supply is contained in the handgrip 10, also is provided with switch 11 on the handgrip 10.

Sensing device 19 is made up of the contact of shell 20, lead 5, lead 7, each lead and spring 13, conducting strip 14.The inboard of shell 20 has two cannelures.In the cannelure of left side a spring leaf 12 is arranged, spring leaf links to each other with lead 5.Be furnished with contact in the cannelure on right side from top to bottom, each contact links to each other with a corresponding lead 7.Be provided with the circular conducting strip 14 of band ears in the shell 20.Conducting strip 14 links to each other with the right-hand member of the arm beam of steelyard 2 by adjusting screw.In the shell 20, pressure spring 13 is housed above the conducting strip 14.The effect of spring leaf 12 is to make conducting strip 14 pressed rightwards all the time, keeps conducting strip well to contact with each electric contact.

The principle of work of multi-functional nimble scale is: after waiting to claim object when packing in the scale pan 1, because the effect of lever, the scale pan 2 descends around the ball 17 of fulcrum, and the right-hand member of the arm beam of steelyard 2 rises around fulcrum ball 17.When rising, the arm beam of steelyard 2 right-hand members drive conducting strip 14 risings by adjusting screw 15.According to weight of object difference in the scale pan 1, conducting strip 14 rests on certain altitude in sensing device 19 inner chambers, at this moment, the lead in sensing device shell 20 left sides is connected with a certain lead 7 by spring leaf 12, conducting strip 14 and shell 20 right sides, so digital weight display just demonstrates the weight of weighed object.

The circuit that numeral weight display 6 is adopted is identical with the electronic scales circuit of selling in the market.Circuit board 8 is contained in the housing 3.

The utility model has the advantages that flexible operation, easy to use.Only need to shovel the scale pan during use and can on the digital weight display of housing 3, demonstrate weight, and can calculate the price of article at any time by the counter on the housing at once with a handgrip object.
