Description
The utility model relates to a kind of mechanical type weighing apparatus of metering, can two-sided indication metering result.
In existing technology, the spring scale scale great majority that use the home market are based on the single face indicating value, but what minority was also arranged is that the double inclined plane spring scale scale of two-sided indicating value is (because of the profile of scale body is the inclined-plane, so be called double inclined plane), the former weak point is that the consumer can not see demonstration numerical value, though the latter can see demonstration numerical value, but because double inclined plane spring scale scale volume is bigger, and heavy its inner structure is complicated, what it adopted is two sleeve gears, rack gear, controlling the action of two cover indicating mechanisms, for guaranteeing the indication weight consistency on the two cover index dials, shape to each parts in indicating mechanism and the gear train, processing technology, accuracy requirement is very high, and need reach consistent, so, on processing and assembly technology, require great effort very much, time-consuming, however, gear train and display pointer also can not be accomplished synchronization action, error can occur and cause the two sides to show the very easy generation contradiction of the inconsistent both parties of numerical value.
The purpose of this utility model provides a kind of simple in structure, reasonable in design, adopt a sets of transmission mechanism, controlling the synchronization action of two cover indicating mechanisms and can guarantee to indicate on the index dial weight consistency, cost is low, volume is little, portably use conveniently, be convenient to adjust two spring scale scales of facing directly of good looking appearance.
The utility model is realized by following measure.
The utility model is to be made of support mechanism, null setting, scale body, compensation mechanism, gear train metering spring, indicating mechanism etc., and support mechanism includes: scale pan frame, the scale pan, supporting frame, long stent, medium-height trestle, tranverse connecting rod are adjusted adjustable plate under seat, upper pendulum bar, fork, tranverse connecting rod, vertical connecting rod, the spring; There are index dial, pointer, pointer nut etc. in indicating mechanism; Gear train sprocket drive spindle, gear, tooth bar etc.; It is characterized in that the scale body profile is a rectangular parallelepiped, its symmetrical both sides face directly be equipped with respectively one the cover by dial sheet and on index dial, pointer, the indicating mechanism that the pointer nut is formed, side in the scale body be fixed with one the cover by gear plate and on the gear pedestal, gear shaft, gear, tooth bar, the tooth bar extension spring, the gear train that the spring pulling-on piece is formed, one end and the fork of tooth bar link, the other end and gear match, gear shaft reaches dial face and fixes by pointer nut and pointer through index dial center mounting hole, and is controlling the synchronization action of pointer in two index dials.
Advantage of the present utility model is: simple in structure, reasonable in design, can guarantee on two index dials indication weight unanimity, and the value of weighing precision height, volume is little, cost is low, portably use convenience, and good looking appearance is a kind of desirable metering outfit.

The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in figure (1), the utility model is that rectangular parallelepiped and the scale body (5) through being stamped to form, compensation mechanism (6), gear train (7), metering spring (8), indicating mechanism (9) wait the part formation by scale pan frame (1), the scale pan (2), support mechanism (3), null setting (4), its profile mainly.Upper end position at scale body (5) is equipped with one by top cover (10), hang spring support (11), the null setting (see figure 2) that zeroing nut (12) zeroing spring (13) etc. are formed, adorn a punching press body base (14) in its lower end position riveting, two symmetries are faced directly by screw and are fixed with dial sheet (15) respectively outside scale body (5), two other perpendicular symmetry face directly be equipped with respectively a removable side plate (16) (side plate treat general assembly finish rear enclosed with), a cover is equipped with by gear plate (17) in a side in scale body (5), and on gear pedestal (18), be fitted on the gear pedestal gear shaft (19) and on gear (20), tooth bar (21), tooth bar extension spring (22), the gear train of spring pulling-on piece (23) (is seen Fig. 3,4) another side relative with it by screw with long stent (24) medium-height trestle (25), tranverse connecting rod is adjusted seat (26) and is fixed on it, last pendulum plate (27), each end of fork (28) tranverse connecting rod (29) respectively with long stent (24), medium-height trestle (25), tranverse connecting rod is adjusted seat (26) and is hinged, its each other end respectively with supporting frame (30), tooth bar (21), tranverse connecting rod holder (31) is hinged, tranverse connecting rod holder (31) is by screw retention (see figure 5) on supporting frame, on fork (28), be screwed one by rivet (32), connect oblique angle iron (33), temperature compensation sheet (34), connect the compensation mechanism (see figure 6) that corner strap (35) is formed, and join by vertical connecting rod (36) and supporting frame (30), the upper end of supporting frame is fixed with scale pan frame (1) with screw, a stop screw (37) is equipped with in the lower end, one end of metering spring (8) hangs on the spring support (11), and the other end hangs on the supporting frame (30) by adjustable plate under the spring (38).Index dial (39) is housed on dial sheet (15), gear shaft (19) reaches two index dial surfaces and perpendicular from index dial center mounting hole, pointer (41) is packed in the two ends (can reach the synchronization action of two pointers of control) of gear shaft (19) respectively by pointer nut (40), at last trim ring (43) is pressed in index dial (39) and upward and with scale cover (42) covers on (parts connected mode unanimity in the two cover indicating mechanisms on the dial sheet, the another set of assembling sequence number in Therefore, omited), at last the scale pan (2) is placed on the scale pan frame (1).
When using the utility model, the thing of will being weighed is placed on the scale pan (2), move down behind supporting frame (30) pressurized that links to each other with scale pan frame (1) (hang over the metering spring (8) on the adjustable plate (38) is stretched under spring support (11) and the spring due to), because supporting frame has moved down and has driven hinged with it upper pendulum bar (27), fork (28), tranverse connecting rod (29) is to lower swing, fork (28) drives tooth bar (21) and moves down, the gear shaft (19) that matches with gear turns round action, and the pointer (41) in the two cover indicating mechanisms that gear shaft (19) links to each other rotates with gear shaft (19) and finishes the indicating value action.(when empty scale, but pointer not nulling position turn zeroing nut align), when weight surpasses busy hour, stop screw (37) with base (14) thus offset and play a protective role.
