Abstract
The utility model relates to a hand-held plate-spring scale, belonging to a measuring apparatus, and the utility model comprises a housing, an indicating needle, a dial and a lever. The utility model is characterized in that a machine frame is arranged in the housing, the middle part of the machine frame is provided with a machine core on which a release spring is arranged, one end of a plate spring is fixed on the machine frame, and the other end of the plate spring is connected with the lever whose the other end is connected with a fan-shaped tooth installed on the machine core. The utility model has the advantages of simple structure, good elasticity due to the adoption of the plate spring, wear resistance and long service life; after the plate spring is overlapped, the elasticity of the hand-held plate-spring scale is largely enlarged, due to the adoption of the lever and the release spring, the hand-held plate-spring scale has less false, high accuracy and large range to a scale pan, and the front and the back faces of the hand-held plate-spring scale have same measuring gauges so as to be convenient for both vendors and purchasers to simultaneously carry out the reading. The utility model is suitable for the measuring activities of industries, commerce and families.
Description
The utility model relates to a kind of portable plate-spring scale, belongs to measurement instrument.
Existing hand spring scale all is made up of extension spring or stage clip, this kind spring balance, though simple in structure, unstable, pointer easily rocks drift, and dial scale is average, and little weight claims thing not see, and the scope of application is little, can only be used for family.And because garden being hit property of spring is poor, easy to wear, serviceable life is short, is not durable, and precision is low, can not be used for big weight weighing article.
It is a kind of simple in structure that the purpose of this utility model is to provide, and working stability is applied widely, precision height, a kind of portable plate-spring scale that the life-span is long.
The purpose of this utility model is achieved in that
The utility model includes shell, metering dial plate, pointer, movement, lever, it is characterized in that: frame is housed in the shell, central rack is equipped with movement, retracing spring is housed on the movement, laminated spring one end is fixed on the frame end, the other end is connected with the lever that is installed in the support bottom by connecting link, the adjustment screw is equipped with at the other end place of lever, its end is connected with sector on being installed in movement by connecting link, the bar of weighing is positioned at the lever middle part, and fulcrum is being weighed between bar and the adjustment screw.
Laminated spring can have a plurality of turriforms that are superimposed as.
Retracing spring one end is overlapped on the movement crossbeam, and the other end is overlapped on the sector.
Can be provided with two-sided metering dial plate on the shell.
Be fixed on the laminated spring of frame end, the other end can be respectively and lever and sector dual link.
The leaf spring and the lever positions that are fixed on the frame end can upper and lowerly be put upside down arrangement.
The utility model is owing to the employing laminated spring, thus good springiness, softness, impact resistance is strong, and is not easy to wear, and long service life is indeformable, after laminated spring connects through tower, forms and makes a concerted effort, and has increased elasticity.Adopted lever and retracing spring, not easy to failure, the work stability, the degree of accuracy height simplifies the structure, and has reduced cost, large and small scale is arranged on the dial plate, applied widely, not only can make pan scale, also can make hook scale and platform balance, the weighing scope makes metering more accurate from 50Gg-100kg, the positive and negative of scale are provided with identical gauging table, are convenient to both parties' reading simultaneously, and are very convenient, being applicable to worker, commerce and family's metering activity, is a kind of desirable portable plate-spring scale.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model movement 3 adopts core of pressure meter (16mpa movement), movement 3 is installed on frame 2 middle parts that are arranged in the shell 1,4 one of Return springs are overlapped on movement 3 crossbeams, the other end is overlapped on the sector 9, after three laminated spring 5 towers connect, one end is fixed on frame 2 ends, the other end is connected with lever 7 by pull bar 6, lever 7 the other end are equipped with and are adjusted screw 8, lever 7 terminations are connected with sector by arm-tie 12, and weighing bar 11 is located at lever 7 middle parts, and fulcrum 10 is being weighed between bar 11 and the adjustment screw 8, just be equipped with on the shell 1, anti-phase gauging table 13 together, pointer is coaxial with the commutating tooth axle.
When using the utility model, portable shell 1 suspension ring, earlier dial scale is transferred to 0 by adjusting screw 8, to be claimed that thing is placed on the hook of weighing then, under action of gravity, lever 7 one ends that are installed in support 2 bottoms hold with connecting link 6 cuttves and are connected, and connect long slab spring stress deformation by the long slab coptis in connecting link 6 and the tower plate Huang 5, when thing is little if weigh, gravity is added on the long slab reed, produces elastic deformation, when gravity increases, vice-minister's leaf spring stress deformation, work, gravity increases again, and the three ply board spring is worked jointly, simultaneously, the lever other end makes sector 9 along with motion by connecting link 12, with two pointers commentaries on classics certain angles that spur gear also rotates and spur gear is coaxial of sector engagement, point out weight, when taking off weight, the retracing spring that is overlapped on movement 3 crossbeams and the sector 9 helps the pointer return, and eliminates the leaf spring free state.
If the utility model is made pan scale, only need other end while and lever and sector gear dual link with laminated spring, the other end of lever adds the counterweight holder and gets final product.
If put upside down arrangement with the leaf spring of dual link of the present utility model and lever positions are upper and lower, will weigh and a little add the scale pan, promptly can be used as table scale.
