Abstract

A table balance comprises a base (1) and a balance arm (2), wherein, a tool holder (10) and an index plate (8) are mounted at the middle part of the base (1); the balance arm (2) is hinged with the tool holder (10); a pointer (7) perpendicular to the balance arm (2) is mounted at the middle part of the balance arm (2); the pointer (7) is opposite to the surface of the index plate (8) on the base (1); two tray racks (5) are mounted symmetrically at two ends of the balance arm (2) respectively; trays (6) are mounted on the tray racks (5); balancing nuts (4) are mounted at two ends of the balancearm (2); a rider bar (3) parallel to the balance arm (2) is mounted at the middle part of the balance arm (2); and a rider (9) is mounted on the rider bar (3) in a slideable manner. The table balanceis characterized in that the surface of the rider bar (3) adopts bidirectional tagging. The utility model can be used for various people, and can be operated in both a left object-right weight mannerand a right object-left weight manner; and both the two manners can weigh out the weight of an object conveniently and accurately.

Description

A kind of counter balance

Technical field

The utility model relates to meausring apparatus, relates in particular to a kind of counter balance.

Background technology

Balance is the instrument of weighed object physique amount, and is widely-used.Most people get used to the own right hand because the right hand is more convenient, when we by proper operation---during right yard of left thing, then the object quality equals the counterweight number and adds the rider number.It is easily practical that the employed balance of prior art uses concerning most people, but the sub-fraction people is still arranged in life, and they are accustomed to the left hand with oneself, and they just do not have so when the operation counter balance and have made things convenient for so.If accidentally object is placed in the pallet of counter balance the right, counterweight has been placed in the pallet of the counter balance left side, when making right thing left side code operations, this makes troubles for our reading, even can make us obtain the data of a mistake; Physical balance is from being designed into use, and generally popularization does not by now all have to consider this problem for them.

Summary of the invention

The purpose of this utility model is in order to overcome the defective of prior art counter balance, the counter balance that provides a kind of various people simple in structure, convenient to use.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of counter balance, comprise base and balance arm, the middle part of base is equipped with knife rest and index plate, balance arm and knife rest are hinged, the balance arm middle part is equipped with the pointer vertical with balance arm, pointer is relative with the index plate surface on the base, the balance arm two ends are symmetrically installed with two tray racks respectively, on two tray racks pallet is housed respectively, the balance nut also is equipped with at the two ends of balance arm respectively, the balance arm middle part is equipped with the rider bar parallel with balance arm, the rider that is slidingly installed on the rider bar, and the mark face that it is characterized in that described rider bar is two-way mark.

Advantage of the present utility model is to adapt to various people and uses, and is very easy to use, both can the right code operations of left thing also can the right code operations of left thing, reading is fast accurate, can both easily weigh up the quality of object exactly.

The counter balance that the utility model provides uses proof by reality, has reached predetermined purpose.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the mark face mark synoptic diagram of embodiment one rider bar;

Fig. 3 is the mark face mark synoptic diagram of embodiment two rider bars.

Among above Fig. 11 is base, and 2 is balance arm, and 3 is rider bar, and 4 is the balance nut, and 5 is tray rack, and 6 is pallet, and 7 is pointer, and 8 is index plate, and 9 is rider, and 10 is knife rest

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Accompanying drawing 1 has been illustrated a kind of counter balance, comprise base 1 and balance arm 2, the middle part of base 1 is equipped with knife rest 10 and index plate 8, balance arm 2 is hinged with knife rest 10, balance arm 2 middle parts are equipped with the pointer 7 vertical with balance arm 2, pointer 7 is relative with index plate 8 surfaces on the base 1, balance arm 2 two ends are symmetrically installed with two tray racks 5 respectively, on two tray racks 5 pallet 6 is housed respectively, balance nut 4 also is equipped with at the two ends of balance arm 2 respectively, balance arm 2 middle parts are equipped with the rider bar 3 parallel with balance arm 2, the rider 9 that is slidingly installed on the rider bar 3, and the mark face that it is characterized in that described rider bar 3 is two-way mark.

Embodiment one:

Accompanying drawing 2 illustrated rider bar 3 the mark face for up and down the mark, Biao Zhu scale direction is opposite up and down; One group is marked with left end is " 0 " point, increases from left to right, and rider 9 moves right as positive scale; Another group mark is " 0 " point with right-hand member, increases from right to left, annotates rider 9 and is moved to the left as positive scale.

Use the sky at ordinary times, during the right sign indicating number of left thing Measuring Object quality, rider is put earlier to left end " 0 " point, and the balance nut at turn adjustment (adjusting) lever two ends makes the balance balance, and pointer should be aimed at center line; During the weighing article, article and counterweight are placed on the pallet middle position, rider moves right as far as possible, then the object mass number equals the counterweight number and adds the rider number; On the contrary, during the right thing Measuring Object quality of left side sign indicating number, rider is put earlier to right-hand member " 0 " point, and rider is moved to the left, and then must the object mass number equals the counterweight number and adds the rider number.

Embodiment two

Accompanying drawing 3 illustrated rider bar 3 the mark face for the centre of rider bar 3 as zero graduation.

Use the sky at ordinary times, rider moves on middle " 0 " point of scale, and the balance nut at turn adjustment (adjusting) lever two ends makes the balance balance, and pointer should be aimed at center line; During the right sign indicating number of left side thing Measuring Object quality, rider moves right then to such an extent that the object quality equals the counterweight number and adds the rider number; Rider is moved to the left then to such an extent that the object quality equals the counterweight number and deducts the rider number.During the right thing Measuring Object quality of left side sign indicating number, rider moves right then to such an extent that the object quality equals the counterweight number and deducts the rider number; Rider is moved to the left then to such an extent that the object quality equals the counterweight number and adds the rider number.
