Description

Pocket convenient balaance

The utility model relates to the pocket convenient balance that a kind of weighing weight of object is used, and belonging to weighs uses weighing apparatus.

The scale of Shi Yonging is broadly divided into two kinds in the market, and a kind of is wood steelyard, and its scale pan volume is big, and sliding weight of steelyard weight is big, and use is carried very inconvenient and the arm beam of steelyard very easily fractures.Second kind is spring balance, but because of spring often lifts easy slacken, is difficult to keep the precision of weighing, causes weighing inaccurate, so do not admitted by people.Chinese patent CN2090524U discloses a kind of " portable type does not have the stone roller Extension steelyard " for this reason, its scale pan is a square, is made up of ABC three parts, and the arm beam of steelyard is an expansion link, sliding weight of steelyard is made of the balance grain, this weighing-appliance has convenient carrying, provides a convenient, but because its scale pan is a combined type, the manufacturing process more complicated, often folding damages easily, when especially claiming heavier object, and fragile pan of a steelyard.Sliding weight of steelyard is replaced by the balance grain, if regulate a carelessness slightly, it is inaccurate just can to occur weighing, and the phenomenon of giving short weight is difficult to be accepted by people.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of easy to carry, weigh accurate, the simple pocket convenient balance of manufacturing process are provided.

The purpose of this utility model is achieved in that it comprises the flexible arm beam of steelyard, steelyard hook, is carved with weight unit on the expansion link, and steelyard hook places the place ahead of the arm beam of steelyard.Its special character is that the scale pan, sliding weight of steelyard are a box body, and the scale pan is an inner box, and sliding weight of steelyard is outer box, and outer lid is on inner box, and the flexible arm beam of steelyard places in the box body.

The purpose of this utility model can also reach by following measure: the porus acusticus internus that is drilled with inboard triangular in shape of inner box, inner ear outwards protrude and are fixed on the porus acusticus internus.Be installed with cord on the inner ear, cord is fixed on the steelyard hook by inner ear.Box body can be arbitrary shape.

Compared to existing technology, the utlity model has following advantage:

1, because the arm beam of steelyard of the present utility model is an expansion link, and the scale pan and sliding weight of steelyard are a box body, when not using, the flexible arm beam of steelyard and steelyard hook are put in the box body, and be easy to carry.

2, owing to be carved with weight unit on the arm beam of steelyard, sliding weight of steelyard is that shape is different with traditional sliding weight of steelyard, so weigh accurately the precision height.

3, manufacturing process is simple, and is easy to use, only need open the lid during use and just can use.

The drawing explanation of accompanying drawing:

Fig. 1 is the utility model structural representation.

Fig. 2 is square scale pan structural representation.

Fig. 3 is square sliding weight of steelyard structural representation.

Fig. 4 is circular scale pan structural representation.

Fig. 5 is that circular sliding weight of steelyard structural representation becomes.

Embodiment describes the utility model in detail below in conjunction with accompanying drawing.

The arm beam of steelyard among the figure (1), sliding weight of steelyard external ear (2), sliding weight of steelyard (3), scale pan inner ear (4), the scale pan (5), cord (6), steelyard hook (7), scale are carried (8), external ear (9).

The arm beam of steelyard of the present utility model (1) adopts the metal arm beam of steelyard, is good with steel stem.Form the long 12cm of every joint by four poles.The long 1.6cm of arm beam of steelyard head end is solid, is drilled with an aperture at long 1.2cm place, uses in order to the scale pan that hangs down to (5).The long 0.5cm of afterbody, wherein tail head diameter is 0.7cm, and the tail end diameter is 0.9cm, and tail head diameter is less than the tail end diameter, and purpose is for push-and-pull arm beam of steelyard convenience.The flexible long 12cm in back of the whole arm beam of steelyard adds the long altogether 14.1cm of afterbody and head end.For the volume arm beam of steelyard that dwindles scale also can be made up of five joints, the long 9.5cm of every joint adds head end and afterbody long 11.6cm etc. altogether after contracting.Scale camel of the present utility model (3) adopts metal material to make, and steel is good.Sliding weight of steelyard (3) matches with the scale pan (5) for lid, can make different shape, be example with square, is respectively equipped with inner ear (4) on three limits of the scale pan (5), inner ear (4) is fixed on three porus acusticus internus on the limit, inner ear (4) is " " shape to outer lug, and cord (6) passes from inner ear (4), tie up in the circle of steelyard hook (7), the long length of side 14cm of the side row scale pan (5), the long 8cm of minor face, or length ratio and be designed to the square etc. that the length of side is 9.5cm after contracting according to the five joint arm beams of steelyard.The concrete dimensions of sliding weight of steelyard (3) designs according to the scale pan (5).Sliding weight of steelyard of the present utility model (3) (square) is a lid, and its concrete size is advisable to cover the scale pan (5), is fixed with external ear (9) on the top of sliding weight of steelyard (3), and external ear (9) is fixed on the little ring, and little ring nail is in the top of sliding weight of steelyard (3).During use, external ear (9) is gone up wire rope handling and is enclosed within on the arm beam of steelyard (1).The shape of sliding weight of steelyard (3) matches with the scale pan (5), can make different shape, though can make different shape, its weight must require to reach standard according to the unit that claims system to the scale pan (5) with sliding weight of steelyard (3), weigh 240 grams as 3 kilograms of scale scales pan, 10 kilograms of scale scales pan heavily should reach 450 grams.Sliding weight of steelyard (3) is corresponding with it.Scale is carried (7) and traditional scale and is carried similarly, is installed on the arm beam of steelyard (1).

During the weighing object, the arm beam of steelyard of the present utility model (1), steelyard hook (7), scale are not carried (8), cord (7) all is placed in the scale pan (5), and covering with sliding weight of steelyard (3) is a pocket capsule, when needing the weighing article, open the lid, promptly sliding weight of steelyard (3) just can use.Betray goods outward or carry very convenient.
