Abstract
The utility model relates to a novel bench scale with two dials and high accuracy. One end of a balance bar hangs a balance poise, and the other end is erected with a seat frame with a salver. The seat frame is supported on the upper surface of the balance bar through a guiding wheel. A double connecting small gear penetrated by a small gear shaft with a pointer is meshed with a rack on the lower surface of the balance bar, and the small gear is meshed with a double connecting big gear. The weight of weighted objects can be directly read from a big dial and a small dial on the front surface and the back surface of the seat frame. The utility model has the advantages of reasonable and compact structure, simple and rapid use and number reading, and quite arresting exploiting prospect.
Description
The utility model relates to the two-sided platform balance of a kind of novel high-precision two dial plates, and it belongs to and comprises the weighing apparatus class of using counterweight or other counterbalance weights.
Present dial type platform balance all is a spring balance.Because scale is to use the very high weighing utensil of frequency, cause measuring misalignment so the spring in the spring balance is tired easily; Though old-fashioned lever scale can overcome this drawback, show defectives such as inconvenient, that precision is on the low side but have.
The purpose of this utility model is to be the dial type platform balance that people provide a kind of intuitive display, tolerance is accurate and have degree of precision.
The technical solution of the utility model can describe according to accompanying drawing.Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is longitudinal sectional views of the utility model mounting.As seen from the figure, the two-sided platform balance of novel high-precision two dial plates contains the support 2 that vertically anchors on the horizonal base plate 1, with the balance stem 4 that is supported on by pivot 3 on the above-mentioned support 2, its right or section terminations, a left side of balance stem 4 are hung with counterpoise 5, its left side or right section set up the propelling sheave 6,6 that is bearing in the pair of parallel configuration ' on the mounting 7 of band pallet 8; Described pivot 3 its two ends are connected with balanced pointers 9; Described balance stem 4 its left sides or right section upper surfaces be the plane that can supply a pair of propelling sheave 6,6 ' smooth rolling, its left side or a right section lower surface then be provided with tooth bar 4 ', simultaneously on a left side or right section termination be provided with obstruction plate 10; Mounting 7 its parallel forward and backward faces of described band pallet 8 be provided with big dial plate 11,11 '; Big dial plate 11,11 ' the center provide band duplex pinion wheel 13,13 ' pinion shaft 12, the two ends set of pinion shaft 12 have weighing pointer 14,14 ', described big dial plate 11,11 ' under portion be provided with respectively little dial plate 15,15 '; little dial plate 15,15 ' anchor at band duplex gear wheel 17,17 ' the two ends of Large Gear Shaft During 16; and described duplex pinion wheel 13,13 ' with the tooth bar 4 of described balance stem 4 left sides or right section lower surface settings ' be meshed, described duplex gear wheel 17,17 ' then and above-mentioned duplex pinion wheel 13,13 ' be meshed.
When the utility model mounting outside joined with the obstruction plate, balanced pointers was over against zero flag, and the indication of big or small dial plate also all is zero.To treat during use that the weighing article place on the pallet, mounting is slowly moved to the support place, up to balanced pointers still till the zero flag.Can read the weight for the treatment of the weighing article this moment by large and small dial plate.For the convenience of using, big dial plate can be put scale 50 lattice, and making pointer whenever walk lattice is 10 gram meterings, and the duplex pinion wheel turns around and can weigh 500 gram weight like this; Allow the number of teeth of duplex gear wheel be the integral multiple (for example 8 times) of duplex pinion wheel simultaneously, and the scale pointer of little dial plate can be installed on the big dial plate, allow the weighing pointer of big dial plate take a round, little dial plate just rotates lattice, and the weighing pointer of big dial plate is just in time opposite with turning to of little dial plate.The indication of reading little dial plate earlier during general reading, the indication of reading big dial plate again get final product, unless the thing less than 500 that is measured restrains.
The utlity model has compact conformation, modern design and intuitive display, advantages such as accurate measurement, and also the two-sided this point that shows simultaneously is different from the place of other weighing utensil especially, and development prospect is considerable.
