Abstract
The utility model relates to a double-side value-displaying anti-counterfeiting balance, a steelyard hook (disc) and a handle are arranged on a scale body, and a balance block is arranged at the end part of the scale body. A main weight is sheathed on the scale body and can move along the scale body, an auxiliary weight is sheathed on the main weight and can rotate around the main weight, and a stopper pin is arranged on the other end of the scale body. The utility model has the advantages that the scale is provided without any randomly disassembled components, so sellers is not easy to counterfeit, the utility model adopts a micrometer principle for micro adjustment and display, so the precision is high. The use method is closed to traditional Chinese steelyard, the manufacture cost is low and is easy to be accepted by small sellers and country self-product sellers, and the structure of the steelyard hook (disc) and the handle can be changed for being used as a bench scale or a table scale.
Description
The utility model relates to a kind of measurement instrument, belongs to weighing apparatus and makes the field.
Background technology of the present utility model: existing false proof metal steelyard, its structure is the cylindrical structure of the arm beam of steelyard, and an end of the arm beam of steelyard is provided with counterweight, and sliding weight of steelyard is enclosed within on the arm beam of steelyard.It is not enough point: trueness error is too big, and is merely able to the single face indicating value.
Purpose of design of the present utility model: avoid the weak point in the existing background technology, design a kind of can visitor, main with sight, the two-sided indicating value Anti-counterfeit steelyard that two-sided indicating value and weighing trueness error are minimum.
Design proposal of the present utility model: the arm beam of steelyard is two-sided indicating value structure, it is the major and minor stone roller structure and the use that matches with the arm beam of steelyard that sliding weight of steelyard adopts the milscale principle design, trueness error is selected between 0.5～5 gram, and whole scale can't arbitrarily be dismantled, and can fundamentally block up and utilize scale to give short weight, entrap client's phenomenon extremely.Its organization plan: a kind of two-sided indicating value Anti-counterfeit steelyard, blade (4) is provided with steelyard hook (dish) (2) and handle (3), counterbalance weight (1) is positioned at the end of blade, main stone roller (6) is enclosed within blade (4) and goes up and move along blade, secondary stone roller (9) is enclosed within main stone roller and goes up and rotate around main stone roller, and backing pin (10) is positioned on the other end of blade.The two sides of blade (4) is shaped on blade Yan degree line (5).Main stone roller (6) is provided with main stone roller scale mark (7), is shaped on secondary stone roller scale mark (8) and major and minor stone roller scale mark (7,8) on the secondary stone roller (9) and is complementary.Spacer pin (11) is positioned at the terminal inboard of secondary stone roller (9) and affixed with the pair stone roller.Secondary stone roller (9) adopts steep-pitch thread to be connected with main stone roller (6).
The utility model is compared with background technology, and the one, this scale does not have any part that can arbitrarily dismantle, so be difficult for playing tricks; The 2nd, adopt the milscale principle, can regulate and demonstration the precision height by trace; Three are to use method near the traditional steelyard of China; The 4th, low cost of manufacture can be accepted on price for the self-produced trade company of cities and towns pedlar and vast rural area; The 5th, the structure that changes title hook (dish) and handle promptly can be used for counter scale or platform balance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a partial structurtes synoptic diagram of the present utility model.
The drawing reference numeral explanation:
1. the 2. 3. 4. 5. 6. main stone roller of blade scale mark of blade of handle of steelyard hook (dish) of counterbalance weight
7. the 8. secondary stone roller scale mark of main stone roller scale mark 9. pair is cut or polish jade with an emery wheel 10. backing pin (11) spacer pin
1 and 2 pair of the utility model is done with narration in conjunction with the accompanying drawings.
As shown in the figure, secondary stone roller (9) moves in blade (4) certain limit with main stone roller (6), and secondary stone roller (9) links with steep-pitch thread with main stone roller (6), and revolute pair stone roller (9) can make this stone roller do the displacement of certain distance on main stone roller (6).
Principle: the distance that known steelyard hook is put between the handle point is L, and the every little lattice of the double-edged scale of blade (4) are represented the N gram, and the graduation range that every big lattice representative is every kilogram is A, and the weight of weighing article is G.
Equilibrium principle according to lever: LG=AP, can determine weight (the P=master stone roller (6)+secondary stone roller (9)=P1+P2) of P.
In addition: the displacement that known secondary stone roller (9) rotates a circle on main stone roller (6) is B (pitch), the scale mark (8) of secondary stone roller (9) left end on week is the S five equilibrium, then each evenly divided is represented the N/S gram, learn that thus the garden Zhou Kedu revolution of secondary stone roller (9) crosses 1 little lattice, the change in location distance of this stone roller on main stone roller (6) is B/N.
When revolute pair stone roller (9), main stone roller (6) position on blade (4) does not change, but because the center of mass point that secondary stone roller (9) acts on the main stone roller (6) has been done to move, thereby original two stone rollers (6 have been changed, 9) centroid position, micro-variation has taken place to the distance of handle (3) fulcrum in the center of mass point that equals P, so reached the effect of inching and little demonstration.
When weighing not, mention handle (3), will lead the zero graduation line that stone roller (6) left end (reference field) is aimed at blade (4), secondary stone roller (9) also transfers to zero-bit, and blade this moment (4) should be the level of state.
When weighing, to lead stone roller (6) moves right horizontal to blade (4), read the main stone roller corresponding blade of (6) reference field (4) scale value, be this thing weight, cut or polish jade with an emery wheel (6) reference field between two scale marks of blade as the master, can determine its weight by rule of thumb, but can produce certain evaluated error this moment, as desire than accurate measurement, then can use secondary stone roller (9), method is: will lead stone roller (6) reference field and aim at a certain scale mark of blade (4) (blade this moment (4) should be slightly nose shape), revolute stone roller (9) makes blade (4) level gradually then, to lead, secondary two cut or polish jade with an emery wheel value corresponding addition separately, be institute's scale object than accurate weight.
