Abstract
A force-transferring structure of an electronic scale sensor relates to a fitting part structure of an electronic weighing device. In the prior electronic scale sensor, the distance between load-bearing components of the prior electronic scale sensor is large, and the bending force exerted on a load-bearing bracket is larger, mechanical deformation is easy to be caused, thereby influencing a measuring result; and at the same time, a weighing bedplate deforms correspondingly, which influences the external appearance of a scale platform. The force-transferring structure comprises a sensor, the load-bearing bracket positioned at the upper part of the sensor and the weighing bedplate positioned at the upper part of the load-bearing bracket, and is characterized in that the plural load-bearing components which are distributed symmetrically are arranged between the load-bearing bracket and the weighing bedplate, wherein, one load-bearing component is positioned at the middle part of the load-bearing bracket. By adopting the force-transferring structure, the load-bearing components at the lower part of the weighing bedplate are evenly distributed, and the load-bearing components can load evenly to lead the weighing bedplate not to be deformed easily; and because one load-bearing component is additionally arranged at the middle part, the force exerted on the corresponding load-bearing components is reduced obviously, the flexural stress of the load-bearing bracket is reduced, the deformation of the load-bearing bracket is avoided, and the accuracy of the weighing is ensured.
Description
[technical field]
The utility model relates to a kind of electronic scale accessory structure, is the electronic scale sensor force transferring structure specifically.
[background technology]
At present, the normal structure that adopts of electronic scales is: pressure transducer one end is fixed in base, and the top of the other end is connected with support bracket, and load spare is established in the top of support bracket, and the platen of weighing is held in the palm in the top of load spare; When weighing, be put in weight of object on the platen of weighing by load spare with on the present support bracket of weighing body, thereby the signal that the pressure transducer that makes an end be fixed in support bracket changes and show weight by display screen.Be everlasting at present and establish on the support bracket everywhere so that load spare to be installed, because of its deviation of gravity center platen center of weighing phenomenon too much appears upwarping when avoiding object on placing the platen of weighing, load spare often is positioned at the Si Jiaochu that closes on of the platen of weighing, distance between the load spare is bigger, when the object quality of being weighed is big, the suffered curved power of support bracket is bigger, easily produce mechanically deform, thereby make pressure transducer produce cross component force, influence measurement result, the platen generation corresponding deformation of weighing simultaneously influences the platform balance outward appearance.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, and a kind of electronic scale sensor force transferring structure is provided, and improves the accuracy of weighing when increasing physical strength.For this reason, the utility model is taked following technical scheme:

As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described load spare is 5.5 load spares comparatively are evenly distributed in the platen below of weighing, owing to shortened the spacing of load spare, make the platen of weighing improve non-deformability; And act on each load spare pressure and reduce, the bending resistance of support bracket also has corresponding raising; If 5 load spares also can too much not need to improve processing, the assembly precision of electronic scales because of load number of packages order when effectively improving the electronic scale weighing ability.
Described load spare is a working of plastics, and it is circular that the upper end is, and establishes step-like blind hole in the middle of it.Load spare is a working of plastics, plays buffer action when placing object, makes bearing support transmit gravity reposefully, reduces deviation; Adopt the load spare of circular upper end to make to claim that itself and heavy platen touch comparatively even, local deformation is taken place to avoid stressed concentrating.
Rectangular and its place, right angle of described support bracket all extends outward and is with free-ended power transmission arm, establishes load spare on the free end.Adopt this structure can make four load spares lay respectively at nearly four jiaos of places of the platen of weighing, economical with materials reduces cost, and effectively reduces the own wt of support bracket.
Be provided with the securing member that is connected both between support bracket and the sensor, described support bracket has the through hole that matches with securing member to wear securing member.
The tapping in described support bracket front is established groove to receive securing member; The back side of described support bracket be provided with match with sensor and with groove rectangle deformation container cavity side by side.Slot opening makes progress, and Open Side Down for the deformation container cavity; The setting of groove makes securing member not be higher than the last plane of support bracket, and rectangle deformation container cavity provides the deformation space of sensor, effectively utilizes the inner space of electronic scales, helps to reduce the whole height of electronic scales, reduces the volume of electronic scales; Groove is positioned at the perforate end of support bracket, and the deformation container cavity is positioned at the other end of support bracket, has the material of certain wall thickness between the two, and the uniform support bracket of wall thickness can pass through the injection molding one-shot forming.
Described support bracket is established load spare place and is had the cylindrical hole that matches with load spare, and the hypomere of described load spare is established step so that it is undertaken on the cylindrical hole; Described power transmission arm is provided with reinforcement.The hypomere of load spare inserts cylindrical hole, and by the step surface of load spare its card is ended at free-ended upper surface; The effect of reinforcement can improve the intensity of power transmission arm.
Described securing member is two bolts arranged side by side, and described load spare is an aluminium casting.Firmly pressure transducer is fixed on the support bracket below by two bolts; Aluminium casting is possessed the weight that imitate to reduce support bracket under the prerequisite of proof strength, rigidity, make that electronic scales weight is lighter puts in end.
Beneficial effect: 1, the structure that is positioned at the middle load spare of support bracket is set up in employing, make the load spare under the platen of weighing distribute comparatively even, the platen of weighing is difficult for distortion, and corresponding each load spare stressed has bigger reducing, reduced the bending stress of support bracket, avoid the distortion of support bracket, thus the accuracy that assurance is weighed.2, adopt with plastics be material and with the platen contact site of weighing be the load spare of circular structure, help when placing object, to cushion, make bearing support can transmit gravity reposefully, reduce deviation, the platen of weighing can touch equably with load spare avoids stressed concentrating and generation local deformation.3, support bracket is provided with that opening makes progress is used to hold the groove of securing member and the deformation container cavity in the provided sensor deformation space that Open Side Down, can effectively utilize the inner space of electronic scales, help to reduce the whole height of electronic scales, reduce the volume of electronic scales.4, support bracket is aluminum products, can pass through the injection molding one-shot forming, and is easy to process, and its weight is lighter under the condition that satisfies intensity, rigidity, is convenient to end and puts.
