Description
The utility model belongs to the Weighing utensil, specifically a kind of spring scale scale.
At present, the measurement instrument that China commerce and trade market is used to weigh is steelyard and lever counter scale mostly.These two kinds of measurement instruments are because its technical construction is simple, the operability that can do to cover is very big, can't apply restraint at the textural of himself, the indicating value scale of these two kinds of weighing apparatus all is to be engraved on the rod member, shows its weighing value with the power position of swimming thallium, and this can only see for the personnel of selling goods, and the shopper is difficult to be certain about, can't exercise supervision to its metering, thus the common phenomenon of giving short weight be difficult to stop, and in use move and operation all very inconvenient.
The purpose of this utility model is to provide a kind of metering performance accurate, and two-sided letter disk shows the weighing value, and both parties can both be simultaneously high-visible, and in use move and operation all very convenient, the measurement instrument that difficult work covers.
The utlity model has the scale pan, movement, chassis, shell and two-sided scale and show, it is characterized in that the scale pan (2) links to each other with bearing frame (5) through the scale pan pillar (3) of bottom, bearing frame (5) joins by the load-bearing lever (4) of lever shaft (53) with movement; Load-bearing lever (4) one ends are contained on the support (36), and the other end is equipped with pulling force metering spring (13), rack gear (33), gear drive (32) and damper (30): shell is equipped with the double-sided display scale on (1).
The utility model has the advantages that: be convenient to assembling and easily debugging, metering performance accurately and reliably, difficult work covers, the intuitive display of weighing is convenient to shopper's supervision.It is simple in structure, and use, conveniently moving are a kind of comparatively ideal Weighing utensils.

Figure 10 is an outside drawing of the present utility model.
From accompanying drawing as seen, the scale pan (2) is positive square, is used for placing being claimed thing, is connected with bearing frame (5) by scale pan pillar (3), and the scale pan (2) can be made into square or circular, is equiped with stop rack (11) near shell side in the above.Bearing frame is connected with load-bearing lever (4) with bearing by lever shaft (53), is contained on the load-bearing lever branching holder (36).Each end of two lever shafts all is equipped with locating sleeve (52), and dog screw (51) is pushed down with locating rack (50).Damper floating lever (29) is housed on the bearing frame, is equipped with above and becomes circle indicator (24), by transmission pulling-on piece (27) with wear pin (26) and be connected with damper drive link (25).One end of damper drive link links to each other with movement frame clamping plate (12) with dog screw (55) with wearing pin (54), and the other end connects damper (30) with wearing pin (28).A pulling force metering spring (13) is housed on the load-bearing lever, top with snap ring (14) by hook (17) and locating pad (18) with wear pin (19) and be connected with spring hanger plate (16).One end of spring hanger plate is equipped with adjusting screw(rod) (20) setting nut (21), and turriform spring (22) is loaded on the movement frame loam cake (23).The other end of spring hanger plate is connected with movement frame clamping plate by wearing pin (15).The bottom of pulling force metering spring is connected by wearing pin (7) with hanging circlip (9) and hanging circlip seat (8) with spring-hanging rod (10), is loaded on the load-bearing lever.The front end of load-bearing lever is equipped with the rack gear (33) and the gear mechanism (32) of band temperature compensation means, and pointer (40) is housed on gear shaft, is subjected to the anamorphic stretching rate of vertical force to be converted to the circumference rotation pulling force metering spring and indicates the value of weighing.The two clamping plates of movement frame (12) is to connect with four connecting-rod bolts (41), stop (6) is housed above, constitute whole movement and be loaded on the chassis (34), scale lock (35) and footing (37) and footing nut (38) are housed on the chassis, be used for the steady of adjustment level and use.Level indicator (42) and damper are housed on the shell (1) regulate port lid (31), monolithic case is connected with the chassis with four M5 screws.Two-sided scale display part is by transparent glass cover (44) and the moving cover of glass trim ring (43), and the index dial on two sides (46), (39) and dial sheet (47) scale pressure ring (45), pointer and hand rest (48) pointer holder (49) are formed.
The rack gear (33) that has temperature compensation means is a feature of the present utility model.It is tooth bar to be connected on the card frame (335) that temperature compensation sheet (336) is housed by tooth bar (331) by a support (338); Be on the card frame (335) of rack gear (33) temperature compensation sheet (336) to be housed.When temperature variation, the length growth rate of pulling force metering spring will produce increasing or dwindle, and the temperature compensation sheet produces the crooked distance that changes the tooth bar transmission when temperature variation, thereby guarantees the indication weighing value accuracy of pointer (40).
Among Fig. 5 321 is support, and 322 is gear shaft, and 323 is bearing holder (housing, cover), and 324 is backboard, and 325 are Back of the body cap, 326 is gag lever post; Among Fig. 6,7 332 is the tooth bar connecting rod, and 333 are extension spring, and 334 are extension spring Frame, 337 is support, 339 for wearing pin; Among Fig. 8,9 351 is back-moving spring, and 352 is support plate , 353 is support, and 354 is positioning sleeve, and 355 are rotating shaft, and 356 is spanner.
