Abstract
The utility model relates to a portable pulling rod calculating weighing apparatus and belongs to the technical field of the measuring device. This portable pulling rod calculating weighing apparatus adopts a push-draw mode structure; weighing levers is composed of major and minor levers; the terminal of main lever is equipped with a scale hook (disk) and a handle; the minor lever can be drew out of the main lever; a pulling rod is composed of a pulling rod and a slider, and the pulling rod can slide on the weighing lever, and has the functions of a plumb and counting. The utility model has the advantages in that 1. Small size, light weigh, high precision, wide measuring range and portability; 2. High mechanical strength and qualified to the use with different seasons and different areas; 3. Used for the commerce clearance and for the consumers to carry about; 4. Due to the counting function, the apparatus even has practicality.
Description
The utility model relates to a kind of portable pull bar calculating scale, belongs to the measurement instrument technical field.
Scale is often to contact the measurement instrument that uses in people's daily life.Common have a steelyard, and its bar is long, and has stone roller, is not easy to carry.Existing portable balance is a spring structure, and its weighing precision is difficult to meet the requirements, and can not use as trade settlement.The portable pull-rod balance of my design, the patent No. 892164506, in light weight though volume is little, be easy to carry, its cutter and cutter hold and be fixed on the collar that can slide along the arm beam of steelyard, not only produce, processing difficulties, and be also convenient inadequately during use.
Order of the present utility model ground is that a kind of improved portable balance will be provided, and it promptly has the portable characteristics of range of weighing, measuring accuracy and spring balance of steelyard, has computing function again, carries, uses more convenient.
This portable pull bar calculating scale comprises the arm beam of steelyard, and cutter and cutter such as hold at part, it is characterized in that forming push-pull structure by the arm beam of steelyard and pull bar, and the adjustable length of the arm beam of steelyard, end is equipped with cutter and cutter holds, and pole face is marked with equidistant weight graduation.Pull bar can slide into opposite side from a side of fulcrum pivot, has the function of regulating the scale balance.Pull bar is marked with the weight index line, a slide rule that can spur is inlayed in the outside, have little balance adjustment function and computing function, corresponding sides of pull bar and slide rule are marked with the calculating graduation, indicate equidistant weight graduation and weight index line on another corresponding sides respectively, the omnidistance weight indicating value on the slide rule equals a unit of weight indicating value on the arm beam of steelyard.
Though the utility model is the improvement of portable pull-rod balance, but because the adjustable length of the arm beam of steelyard, two bars of scale all participate in balance adjustment with the weight of self, especially pull bar adopts plus-minus method to carry out little balance adjusting method of balance adjustment and slide rule, and has a computing function, realized under the constant situation of range, precision at scale, with smaller volume, lighter weight, obtain bigger range and degree of precision and scale is easy to carry, promptly can use, also can carry use for the consumer as trade settlement.
Further describe structure of the present utility model and principle of work below in conjunction with drawings and Examples.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is its left view.
1 is the weight graduation among the figure, the 2nd, and the length-adjustable arm beam of steelyard, the 3rd, weight index line, the 4th, fulcrum pivot holds, the 5th, fulcrum pivot, the 6th, the force cutter, the 7th, the force cutter holds, the 8th, pull bar, the 9th, pull bar calculates graduation, and the 10th, slide rule calculates graduation, the 11st, slide rule, the 12nd, the graduation of slide rule weight, the 13rd, slide rule weight graduation index line.
The length-adjustable arm beam of steelyard (2) and pull bar (8) the composition push-pull structure that matches, the end of the arm beam of steelyard (2) are equipped with fulcrum pivot (5) and cutter and hold (4) and force cutter (6) and cutter and hold (7), and pole face is marked with weight graduation (1). Pull bar (8) is marked with weight index line (3), and slide rule (11) is inlayed in the side, and corresponding sides of pull bar and slide rule are marked with calculates graduation (9) and (10), indicates respectively weight graduation (12) and weight index line (13) on another corresponding sides.
Scale is when zero point, respectively there are a fixed bar and an active pull rod in the fulcrum pivot both sides, both sides are equal in weight, be in poised state, when force cutter (being steelyard hook or dish) when mounting the article with constant weight, the inevitable disequilibrium of scale, pull bar is moved to the fixed bar direction, search out new equalization point, at this moment pull bar must have a displacement, and its long measure that moves is namely claimed the corresponding unit of weight of article. Because by fulcrum, the weight that fulcrum one side reduces was added in the opposite side of fulcrum simultaneously when pull bar moved, this moment, pull bar was to carry out balance adjustment with the form of addition and subtraction, It is identical with the working method of existing steelyard all by behind the fulcrum. When being claimed article lighter, or will accurately judge the weight of article the time, the pulling slide rule makes scale be in level, and the graduation of interpretation weight can draw gravimetric value. When need calculate the value of article, aim at respective value on the pull bar (weight numerical value or unit price numerical value all can) with " 1 " on the slide rule, find another numerical value (unit price numerical value or gravimetric value) at slide rule, its numerical value of aiming on the pull bar is exactly result of calculation numerical value.
Select different technical parameters, such as the distance of the length of bar, weight, two cuttves, can produce the series of products of different ranges, the geometry no requirement (NR) of arm beam of steelyard sectional area.
Application example: the pull bar of present embodiment and the arm beam of steelyard are made by metal pipe material and wire rod, and the sectional area geometric configuration is circular, and the arm beam of steelyard launches long 30 centimetres, shorten 16 centimetres of durations, long 16 centimetres of pull bar, scale launches 42 centimetres of total lengths, 20 millimeters of the distances of two cuttves, deadweight 250 grams, range 0-3 kilogram.
