Abstract
The utility model provides a portable automatic indication hanging scale. It scales and automatically displays the weight of the heavy object by the synchronous rotation of the weight wheel, the weight cam and the scale disc. The outer edge line of the weight cam is an Archimedes spiral, and the lifting rope is wound in the outer edge groove of the weight cam. The utility model discloses simple structure, convenient operation, the weighing precision is high, portable.
Description
The utility model relates to a kind of Portable Automatic indication steelyard, belongs to the weighing instrument of using counterbalance weight.
At present, the domestic steelyard that generally uses, shaft is long, and inconvenience is carried, and necessary manually sliding weight of steelyard during weighing is during operating cost; Though spring balance energy self-poise indicates weighing, uses when long, elasticity coefficient changes and influences precision, and simultaneously, the scale of spring balance is intensive, and reading error is bigger.
The purpose of this utility model is to propose a kind of precision height, can self-poise and indicate the Portable Automatic indication steelyard of weighing.
Portable Automatic indication steelyard is characterised in that it is by dial disc (1), negative stone roller cam (2), bogie wheel (3), bolster (4) with indicate bearing support (5) to form, bolster (4) passes the garden heart of dial disc (1), bogie wheel (3) and the utmost point heart of negative stone roller cam (2), be installed in then on the indication bearing support (5), dial disc (1), negative stone roller cam (2), bogie wheel (3) are connected as a single entity.The border line of negative stone roller cam (2) is a spiral of Archimedes, and equation is ρ=α θ.Mound lifting rope one end is connected with stone roller, and the other end is fixed on the negative stone roller cam, and lancet one end is connected with suspension hook, and the other end is fixed on the bogie wheel.
Mound lifting rope was wrapped in the border groove of negative stone roller cam when the purpose of this utility model was achieved in that weighing, the lancet rope forms a lever weighing system in the border groove of bogie wheel, negative stone roller cam is owing to be subjected to the effect of bogie wheel moment, rotate, make the application point occurred level displacement of stone roller on cam, moment increases gradually, after the equalising torque, negative stone roller cam turns over certain angle, simultaneously, dial disc also rotates an angle thereupon synchronously, thus the direct self-indicating scale value of indication bearing support.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is a synoptic diagram of the present utility model.
Fig. 2 is a schematic diagram of the present utility model.
Fig. 3 is a structural drawing of the present utility model.
Dial disc (1) is gone up according to the heavy equidistant weighing scale that is carved with of stone roller, bolster (4) passes the garden heart of dial disc (1), bogie wheel (3) and the utmost point heart of negative stone roller cam (2), be installed in then on the indication bearing support (5), dial disc (1), negative stone roller cam (2), bogie wheel (3) are connected as a single entity.The border line of negative stone roller cam (2) is a spiral of Archimedes, and equation is ρ=α θ.Cleaner rope (6) one ends are stuck in hole (7), then, are coiled on the bogie wheel (3).Mound lifting rope (8) one ends are stuck in hole (9), and the other end hangs sliding weight of steelyard.When cleaner is hung weight down, cleaner rope (6) spurs bogie wheel (3) vertically downward and axially rotates, simultaneously, negative stone roller cam (2) and dial disc (1) synchronously rotate, make mound lifting rope (8) on negative stone roller cam (2), thus the center of gravity occurred level direction displacement of stone roller, when reaching equilibrium state, dial disc (1) turns over certain angle, and the pointer (10) on the indication bearing support (5) directly indicates the weighing value.
Portable Automatic indication steelyard owing to adopt cam gear, is difficult for during the weighing balance swinging, and adopts the disk display result simultaneously, has improved weighing efficient and weighing accuracy, and it is easy to use, and is simple in structure, can make of plastics or other metal material.
Claims (1)
- Portable Automatic indication steelyard, form by dial disc (1), negative stone roller cam (2) bogie wheel (3), bolster (4) and indication bearing support (5), it is characterized in that bolster (4) passes the garden heart of dial disc (1), bogie wheel (3) and the utmost point heart of negative stone roller cam (2), dial disc (1), negative stone roller cam (2), bogie wheel (3), bolster (4) are connected as a single entity, and are installed on the indication bearing support (5).The border line of negative stone roller cam (2) is a spiral of Archimedes, and its equation is ρ=α θ.
