Abstract
The utility model relates to a double-pointer multi-circle rotation type lever scale balance series which takes a bench scale as a main component. In a full closed balance shell, a first lever of a lever system is connected with a load bearing mechanism, and an X-order lever is connected with a pendulum mechanism which is provided with a sector gear or a toothed rack of a scale indicating device. A balance pan or a balance hook is under the action of a weighing object, and with the descending and reduction, the balancing equally and the division of the balance pan or the balance hook is amplified to indicate the quality or weight of the weighing object. Each of the balance series is provided with two scales, and each scale is provided with two pointers which rotate clockwise. The precision of each balance reaches from 1/400 to 1/2500, and each balance has the characteristics of automatic weighting, direct reading, no easy cheat, small structure and beautiful appearance.
Description
The utility model relates to a kind of weighing apparatus, especially based on two pointer multi-turn swinging lever scale dials of counter scale.
Of the prior art pair of pointer multi-turn swinging lever scale dial is detected in Chinese patent technology high precision lever scale dial (patent No. 95200805.X, June 26 1996 Granted publication day).It has a major defect, and the pointer that a scale must be arranged in its two sides scale when being exactly weighing is by counterclockwise rotating indication.And people only are accustomed to using the move in the direction of the clock instrument of indication of pointer, so this patented technology is difficult to practical application and promotes.The reason that causes wherein the pointer in the scale to rotate counterclockwise is that the pointer rotation direction in the two sides scale of scale when stressed is identical, and then the back side is relative for this two sides scale.Meet being designed to of people's use habit: if the two sides scale of scale is settled in the relative mode in the back side, pointer when stressed in this two sides scale just must rotate by opposite each other direction, that is: the pointer in scale clockwise rotates, and the pointer in the another side scale rotates counterclockwise; Vice versa.Design only so, no matter just can weighing the time be which face reading of data from scale, the pointer of being seen all is the correct effect that moves in the direction of the clock and indicate.
Order of the present utility model ground is to provide a kind of totally enclosed, precision (accuracy) to reach 1/400～1/2500 the two pointer multi-turn swinging lever scale dials of series.They all have the feature that the pointer in every scale all moves in the direction of the clock and indicates during weighing.
The utility model is made of group parts such as load carrier, scale shell, lever system, pendulum mechanism, scale indicating devices.In a totally enclosed scale shell, the emphasis of first lever is connected by the third party with the carrier bar of load carrier in the lever system, the force of X lever is connected with the flexibility band (or flexible filaments) of pendulum mechanism, and the sector gear or the tooth bar of scale indicating device is installed in the pendulum mechanism.Acted on the scale pan or steelyard hook by the weighing thing, acting force passes to lever system by carrier bar, passes to pendulum mechanism again with the balance five equilibrium after this system dwindles by lever ratio, passes through the break-in of scale indicating device again, decompose and amplification, indicate by the actual mass of weighing thing (weight).
Have two levers in the lever system at least, the range of scale is big or precision is high, and used lever is just many; Otherwise it is then few.
All be that force and emphasis flexibly connect by the third party between adjacent two levers, the order of connection is from first lever, second lever ... up to being connected in series of X lever, the X lever can directly be second lever, i.e. X 〉=2.
The cross sectional shape of the fulcrum shaft knife of each lever part is a leg-of-mutton one side and geometric configuration after the straight flange of one and half garden shapes (comprising more than half garden shape and smaller part garden shape) overlaps in the lever system.
One end of X lever is installed with the counterbalance weight of band micrometer adjusting screw, in order to the adjustment of pointer zero-bit and the adjustment of lever system.
Pendulum mechanism in fact also is a quadrant lever, and balance staff is a fulcrum, attaches most importance in the tangent point of contact of the eccentric wheel of flexible band (or flexible filaments) and this mechanism upper end, and the sector gear of this mechanism's other end or tooth bar are the force end.Eccentric effect is that the compensate function by self remedies the limitation of quadrant lever, makes graduated circle have five equilibrium.
The scale indicating device is made of gear train, pointer, index plate etc.It has the two sides scale, and two pointers and two and the corresponding graduated circle of pointer are arranged in every scale, and these two graduated circles are printed on the same index plate.Again respectively with the kilogram gear that kilogram pointer is installed with the engagement of one group of part order such as gram gear of gram pointer is installed, form first scale system through the sector gear of gear train or tooth bar, triple gear and triple gear; Through the sector gear of gear train or tooth bar, duplicate gear, triple gear and triple gear again respectively with the kilogram gear that kilogram pointer is installed with engagements of another group part orders such as gram gear of gram pointer is installed.Form second scale system, this two sides scale (system) is settled in the relative mode in the back side.The acting force that passes over, break-in and decomposition through the gear train of described scale indicating device, the pointer that drives first scale is done the clockwise direction rotation, the pointer that drives second scale is done counterclockwise to rotate, no matter thereby when having realized weighing being any face scale reading of data from scale, the pointer of being seen all is the invention order ground that the clockwise direction be accustomed to by people is rotated indication.
The pinion of triple gear in sector gear or tooth bar and first the scale system, the middle gear of triple gear and gear wheel are then respectively with the kilogram gear that kilogram pointer is installed with the gram gearing mesh of gram pointer is installed; Sector gear or tooth bar again with second scale system in the m gearing mesh of duplicate gear, the n gear of duplicate gear and the pinion of triple gear, the middle gear of triple gear and gear wheel again respectively be installed with kilogram pointer the kilogram gear and be installed with the gram pointer the gram gearing mesh.
In the above-mentioned scale indicating device with the sector gear of the pinion of the triple gear of first scale system or tooth bar, the n gear of duplicate gear in the pinion wheel of each triple gear in the disc system, second the scale system twice, all manufacture conical gear or spiral gear, then can design the scale indicating device that the two sides scale is 5 °～35 ° of angles of interior relatively inclination.
The gram pointer of above-mentioned two kinds of scale indicating devices is 2～5 with the rotating ratio of kilogram pointer, and promptly when a kilogram pointer when turning around, the gram pointer can be designed to or change 2 circles or change 3 circles or change 4 circles or change 5 and enclose.Like this, just can design the series scale indicating device of variety classes (counter scale class, steelyard class, portable class), different model (4 kilograms, 10 kilograms of maximum weighings, double centner, 5000 kilograms etc.), different accuracy (1/400,1/1000,1/2500 etc.), to satisfy multiple coupling requirement of the present utility model.
The utility model provides a kind of totally enclosed, precision can reach two pointer multi-turn swinging lever scale dial series of 1/400～1/2500, has realized all the move in the direction of the clock invention order ground of indication of pointer in their every scale.Have automatic weighing, look cheating directly perceived, difficult and the bijou characteristics of volume read.
In conjunction with the accompanying drawings the utility model is described with embodiment below.
Fig. 1 is the 1st and the 2nd embodiment Facad structure synoptic diagram.
Fig. 2 is the 1st embodiment side structure synoptic diagram.
