Abstract

The utility model relates to an auto-display weight machinery balance, which is formed by double levers and supporting frames through shaft connection and slide connection. The main stressed member is the lever. Under the balanced state, a weight is hung, and then the weight value can be displayed by the auto-display weight machinery balance.

Description

Auto-display machinery balance

The utility model relates to a kind of double lever weighing device, especially can show weight automatically.

In the present known title, bar claims, tray scale is from great, and overall dimensions are big, increases along with weighing to move to claim holder or increase counterweight.Though yet less need not the moving of deadweight and profile claims holder, changes counterweight in the spring balance class, along with access times increase, the prolongation of time, its degree of accuracy is difficult to assurance as the spring of the parts of weighing.Electronic scale is converted into electric weight with non electrical quantity and measures, though stable accuracy is easy to use, needs that power supply, cost are also high, inconvenience is carried.

The purpose of this utility model provides a kind of improved weighing device.It not only can be from heavy and light, and overall dimensions are little, and weighing process do not change counterweight, shows automatically and weighs, and can also make precision keep stable, easy to carry.

The purpose of this utility model is achieved in that any is connected with support at driving lever one end of hanging weight, is slidingly connected with support two parts simultaneously.Some axle of the passive bar and support of band counterweight is connected, and its part is slidingly connected with the part of support and driving lever simultaneously.When not having weight, the total system of title is in initial equilibrium conditions.When being acted on driving lever when weighing, driving lever is passed to passive bar by the sliding axle that is slidingly connected with it by a certain percentage with gravity, makes double-lever system lose initial balance, sets up new balance according to lever balance theory.The display part of weight scale also changes thereupon.

Owing to adopt such scheme, only need weight is hung up properly, no longer carry out other operation, gravimetric value can show.Lever system is only adopted in inside, and is simple in structure.

Below just in conjunction with the accompanying drawings and embodiments the utility model is further specified.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is the structural map that machinery claims embodiment.

1. claim that driving lever (3) one ends are connected with support (2) axle among thing hook 2. supports 3. driving levers 4. passive bar 5. stationary shaft 6. sliding axles 7. stationary shaft 8. counterweights 9. sliding axles 10. weight pointers 11. index dial Fig. 1 among the figure.Driving lever (a 3) part is slidingly connected with support (2).Driving lever (a 3) part is slidingly connected with passive bar (a 4) part and support (2).Passive bar (4) a bit is connected with support (2) axle.Sliding axle (6) is connected with claiming thing hook (1) stationary shaft.Weight pointer (10) is fixed on the passive bar (4).Index dial (11) is fixed on the support.

In embodiment illustrated in fig. 2, be in the initial equilibrium conditions of zero graduation when pointer (10), after claiming thing hook (1) cheek weight, thing is heavy to be assigned on the sliding axle (9) former double-lever system out-of-balance condition by a certain percentage, driving lever (3) clockwise rotates, sliding axle (6), sliding axle (9) move down, and passive bar (4) rotates counterclockwise, thereby set up new balance, weight pointer (10) is gone up at index dial (11) and is pointed to this weight scale, is claimed thing weight just to show automatically.

Claims

A kind of machinery claims by driving lever, passive bar, coupling shaft and support etc. are linked in sequence, it is characterized in that: driving lever (3) one ends are connected with support (2) one side stationary shaft (5), driving lever (3) is gone up near the sliding tray of stationary shaft (5) and a vertical sliding tray on the support and is slidingly connected with the sliding axle in the groove (6), sliding tray and sliding tray of last vertical sliding tray of support (2) and passive bar (4) top that driving lever (3) is gone up away from stationary shaft (5) are slidingly connected with the sliding axle in the groove (9), passive bar (4) middle part is connected with support (2) stationary shaft (7), passive bar (4) bottom has pointer (10) and counterweight (8), index dial (11) is fixed on support one end, and the thing of being weighed acts on the sliding axle (6) by claiming thing hook (1).
