Abstract
The utility model discloses a level type mechanical automatic balance, which is an automatic weight measuring device and is suitable for measuring weight in material mixture, management, families, etc. The device is characterized in that a suit of levers are installed below a tray; the end of the driving lever is connected with a transmission pair; the end of the driven lever is connected with a measuring ball. When a heavy object is put on the tray or on a balance board, the levels are impelled to motion by gravitational action; the measuring ball is made to roll to a definite position; simultaneously, the transmission pair is driven to rotate; the weight scale of the corresponding heavy object is displayed out.
Description
The present invention relates to the weights and measures field, particularly the tolerance weight-measuring device.
In the weighing apparatus field, most widely used weight-measuring device be steelyard since steelyard when using, after weight must being mentioned together with scale, could gravimetry, very inconvenient.Along with rapid development of economy, people's demand be fast, accurately, convenient, economic, durable Automatic balance.Therefore the weighing apparatus product constantly updates, and mainly shows, in recent years spring automatic balance of Chu Xianing and electronics automatic balance.And above-mentioned weight-measuring device reflects their weak point in application in practice, as: after spring balance used a period of time, elastic force weakened, and error occurs, needed often to adjust or change spring, and price is more expensive.The electronic scales price is more expensive, and not portable repairing, and their check weighing amount is all very little, so their usable range is limited, can't extensively be accepted use by people.
The purpose of this utility model is that a kind of low cost of manufacture will be provided, and usable range is wide, not the full-automatic bar of the mechanical lever-type of rapid wear ring.
Check weighing scope of the present invention, from 0 to 1000 kilogram all can be used, and simple in structure, cheap, be convenient to implement, can be used as the regeneration product of weight-measuring device.
The present invention forms according to the gravity work production principle design, when pallet is put tested weight, under the effect of gravity, promote lever motion, the end of driven lever rolls the check weighing ball, and initiatively lever is terminal drives transmission and pay to rotate and makes the pointer rotation, when the check weighing ball is rolled into position with the weight balance, batch pin rotates to the relevant position on the display panel, and shown scale is the weight of object.When gravity is eliminated, out of trim, the check weighing ball under leverage, the initial point of rolling back, transmission is simultaneously paid and is driven pointer and turn to zero position.
According to above principle, the series of levers formula mechanical automatic scale that the present invention designs, simple in structure, cheap, mechanical wear is little, must often not adjust maintenance, convenient durable, accurately and reliably.
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is a disc type lever machinery automatic balance structural representation.
Fig. 2 is a pound formula lever machinery automatic balance structural representation.
As shown in Figure 1, pallet (1) is connected with longitudinal holding pole (2), longitudinal holding pole (2) is connected with fork-shaped pole (3), fork-shaped pole (3) is to be combined by two poles, there is a space centre, so that lever can move betwixt, this axle of active lever shaft (4) that connection energy in fork-shaped pole (3) upper end freely rotates is connected with the upper end of active lever (5), the lower end of lever (5) is connected on the gear shaft (7) with transmission levers (6), the two ends of gear shaft are connected with case (12), and can freely rotate, transmission levers (6) is not held with driven lever (9) top strand and is connected in active (8), can rotate flexibly, the not end of driven lever (9) is connected in check weighing axle (10) mutually with check weighing ball (11) and is positioned at the check weighing track (18) that is fixed on the locating shaft (19) and does freely to rotate, gear (13) is fixed on gear shaft (7) and goes up and mesh with pinion wheel (14), pinion wheel (14) is installed on the central shaft (15) that two ends are connected with case, and can freely rotate, fixedly mounting pointer (16) on the axle and going up rotation at display panel (17), locating shaft (19) two ends are connected on the case (12), middle being connected with check weighing track (18) also can rotate, counterweight (20) is at check weighing track (18) right-hand member, check weighing track right-hand member has a calibration bolt (21), tightening up card (22) and can tighten the check weighing track at any time on the case.
Fig. 2 is identical with the principle of work of Fig. 1, and its characteristics are that longitudinal tie (1) is connected with fork-shaped pull bar (3), and pound pole (2) upper end is connected with case (12), and the lower end is connected with general pound plate, and the counterweight stone roller changes the bigger general pound stone roller of weight ratio into.
In sum, the present invention can make serial weight-measuring device.
1, tested weight is smaller, and weight can be cancelled counterweight stone roller (20) in the scope of 5 kilograms of display panels, and its structure is more tightly played, and precision is higher.
2, weight surpasses when scope is promptly greater than 5 kilograms shown in the display panel, can increase counterweight (20) by Fig. 1, and its measurement range is below 15 kilograms.
When 3, weight surpasses 15 kilograms, as shown in Figure 2 weight is shelved on pound plate, can on display panel, reads numerical value correspondingly,, can increase pound stone roller (20) if when weight weight surpasses scope shown in the display panel.
Same principle as required, can be made the plurality of specifications in 0 to 1000 kilogram, the lever type mechanical automatic balance of different meterings.
If needle deflection zero point before using, scalable calibration bolt (21) makes pointer positive sense zero, after finishing using, the check weighing track is placed on tightens up card (22) and locates, and lock.
Claims (4)
1, the lever type mechanical automatic balance is involved in Weight-measuring device, by pallet (1) or pound plate, longitudinal holding pole (2) case (12) display panel (17) and driving member are formed, it is characterized in that driving member is paid by cover lever and a transmission constitutes, initiatively lever (5) upper end is connected with active lever shaft (4), this axle is connected with fork-shaped pole (3) and longitudinal holding pole (2), initiatively the not end of lever (5) is connected on the gear shaft (7) with the upper end of transmission levers (6), the upper end strand of lower end and driven lever (9) is connected in active (8), and the lower end of driven lever (9) links to each other with check weighing ball (11); The gear that transmission is paid (13) is fixed on the gear shaft (7), drives pointer (16) with little moving gear (14) engagement and goes up rotation at display panel (17).
