Description

A kind of anti-tilting, overturn-proof structure scale

Technical field

The utility model relates to a kind of structure scale preventing weighing platform from tilting, overturning, and particularly relates to scale edge of table and is subject under bigger pressure condition, prevents the structure scale that weighing platform tilts, overturns.

Background technology

In the application occasion of scale, often have the situation (on such as vehicle, scale is weighed, and tire is wanted first to roll over from weighing platform edge) of vehicle wheel edge of table relatively heavy per unit volume, during weighing platform edge pressurized, have the trend of tilting.Owing to the bearing part of scale is inside weighing platform, when there being the edge being pressed in scale more energetically, turning moment can be produced around bearing part, thus cause weighing platform to tilt, the upset of weighing platform can be caused when serious, bring damage.When weighing platform weight is less and weighing platform size is less, it is easier to tilt, overturn.

In order to prevent weighing platform from overturning, using at present and adding vertically spacing mode, when the little tilting of weighing platform, vertical spacing prevention weighing platform tilts further, prevents the harm that bigger tilting, upset bring.But some defects of this structure: weighing platform often tilts at certain limit back warp, are lost to sensor etc., finally affect precision and the service life of scale.

Detailed description of the invention

Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; elaborate more details in the following description in order to fully understand the utility model; but the utility model obviously can be implemented with multiple this alternate manners describing that are different from; those skilled in the art can make similar popularization according to practical situations, deduce in the case of without prejudice to the utility model intension, therefore should not limit protection domain of the present utility model with the content of this specific embodiment.

It should be noted that Fig. 1 to Fig. 4 is all only used as example, it is not to draw according to the condition of equal proportion, and should not be construed as limiting in this, as to the protection domain of the utility model actual requirement.

As depicted in figs. 1 and 2, anti-tilting, the structure scale of anti-canting include weighing platform 1 and at least three sensor 4；Weighing platform 1 has at least one and rolls limit 2 for scale on wheel and lower scale；On the frontal plane of projection of vertical direction, the projection passing straight through sensor 4 described at least two at any one the projection place rolling limit 2, or the projection of at least two sensors 4 is fully located at the side that the wheel same pointed relative to the projection of any one the direction of motion rolling the 2 play scales in limit rolls the straight line projecting place on limit 2.

Further, as depicted in figs. 1 and 2, structure scale include at least three for supporting the bearing part 5 of sensor 4, bearing part 5 is connected with base 3；On the frontal plane of projection of vertical direction, at least two sides being positioned on the straight line rolling limit 2 place or being positioned at straight line in bearing part 5, and residue bearing part 5 is positioned at the opposite side of straight line.

Further, as depicted in figs. 1 and 2, weighing platform 1 is rectangle, and the quantity rolling limit 2 is two and be arranged in parallel, and the quantity of sensor 4 is four；Sensor 4 is centrosymmetric setting relative to the cornerwise intersection point of weighing platform 1.

Further, as shown in Figure 4, sensor 4 is completely covered by weighing platform 1, rolls limit 2 and integrally caves in towards the direction making weighing platform 1 area reduce.

Further, as depicted in figs. 1 and 2, the part that sensor 4 is not covered by weighing platform 1 be provided above cover plate 6.

Further, as it is shown in figure 1, the supporting way that bearing part 5 uses is roly-poly type support or threaded rod supports.

Further, as it is shown on figure 3, on the frontal plane of projection of vertical direction, weighing platform 1 is rectangle, and the quantity rolling limit 2 is four, and bearing part 5 is positioned on the diagonal of weighing platform 1.

As shown in Figure 2, on the frontal plane of projection of vertical direction, sensor 4 intersects with rolling limit 2, bearing part 5 distance is made to roll limit 2 nearer, when of weighing platform 1 rolls limit 2 by coming from outside downward pressure (pressure during such as scale, lower scale on wheel), the moment making the other end of weighing platform 1 tilt can be efficiently reduced, decrease the tilting of weighing platform and the possibility of upset.

As in figure 2 it is shown, bearing part 5 is positioned at the side rolling the straight line that limit 2 projects place, this side is that wheel rolls the side pointed by the direction of motion of scale under limit relative to same.From lever principle, when of a weighing platform 1 rolls limit 2 by coming from outside downward pressure (pressure during such as scale, lower scale on wheel), there is not the moment making the other end of weighing platform 1 tilt on direction, therefore avoid tilting and the upset of weighing platform.

As it is shown on figure 3, bearing part 5 is positioned at and rolls limit 2 and project on the straight line at place.From lever principle, when of a weighing platform 1 rolls limit 2 by coming from outside downward pressure (pressure during such as scale, lower scale on wheel), the position of pressure passes through bearing part 5, the moment that tilts of the other end making weighing platform 1 producing is zero, it is to avoid the tilting of weighing platform and upset.

Compared with prior art, positive progressive effect of the present utility model is: the utility model by the bearing part of the sensor of scale to the outer side shifting of scale, the bearing part making the sensor of scale moves to weighing platform edge or exceeds weighing platform, decrease the moment being subject to make weighing platform tilt, overturn during bigger pressure at weighing platform edge, thus prevent tilting and the upset of weighing platform, reduce the loss of sensor, improve reliability, ensure that the service precision of scale, extend the service life of weighing platform.

Although the utility model is open as above with preferred embodiment; but it is not for limiting the utility model; any those skilled in the art are without departing from spirit and scope of the present utility model; possible variation and modification can be made; every content without departing from technical solutions of the utility model; any modification, equivalent variations and the modification made above example according to technical spirit of the present utility model, each falls within the protection domain that the utility model claim is defined.
