Abstract
The utility model relates to a scale platform of a measurement ware, in particularly to a four-sensor scale platform which comprises a base, a sensor arranged on and connected with the base, a scale body and a platform surface; wherein the scale body is a frame structure; four sensors are respectively arranged on and connected with the four corners of the base; furthermore, a lower steel bowl on the upper part of each sensor is connected with an upper steel bowl connected with the lower part of the scale platform through a steel ball; either the upper steel bowl or the lower steel bowl or both of the upper steel bowl and the lower steel bowl have one spherical surface contacting a tennis ball. After being improved, the scale platform has four supporting points, which changes one point stress condition of the traditional scale platform; therefore, when the scale platform is stressed by the same external force, the bending moment exerted on the scale body is greatly reduced; hence the utility model has the advantages of relatively sound anti-deviated load capacity, thin scale platform, low weight, easy movement and automatic reset.
Description
Technical field
The utility model relates to a kind of weighing platform of measurement instrument, especially a kind of four-sensor weighing platform.
Background technology
Known electronic platform scale weighing platform generally is made up of base and scale body and sensor, and the scale body is a supporting part, and base is a supporting member, and a sensor is fastened between base and the scale body.Because its sensor of weighing platform of this kind structure is positioned at the middle part of scale body, be some supportings, stressed around the weighing platform, especially four jiaos stressed after, or when being subjected to external side force, the suffered moment of flexure of its scale body is bigger, thereby the anti-bias load ability is relatively poor, so higher to the request for utilization of scale body, for improving the anti-bias load ability of scale body, generally the scale body is designed to thicker steel-casting or weldment,, is difficult for moving so weighing platform is also heavier.Secondly since between sensor and scale body and the base for fixedlying connected, the scale body is difficult for returning to original state after being subjected to bigger side force.
Summary of the invention
It is strong that technical problem to be solved in the utility model provides a kind of anti-bias load ability, can automatically reset, and weighing platform is thin, in light weight the four-sensor weighing platform that is easy to move.
Technical problem to be solved in the utility model realizes by following technical proposal: a kind of four-sensor weighing platform, comprise base, be installed in sensor, scale body and table top on the base, it is characterized in that: described scale body is a framed structure, four jiaos of base are fitted with four sensors respectively, and the lower steel bowl on every sensor top is connected with the upper steel bowl that is connected the weighing platform bottom by steel ball, and upper and lower steel bowl has a sphere that contacts with steel ball at least.
Adopt technique scheme, four jiaos of the scale body are provided with four sensors, make the scale body be four-point supporting, some force-bearing situations of traditional platform balance have been changed, therefore weighing platform of the present utility model is after being subjected to identical external force, and the suffered moment of flexure of scale body reduces more, has anti-bias load ability preferably, under scale body section modulus the same terms, the suffered bending stress of its scale body also descends thereupon, so when bearing under the identical stress condition, the sectional dimension of scale body can reduce, adopt the rigid frame structure can satisfy request for utilization, so the depth of section of scale body can reduce, weighing platform weight is fallen gently, is easy to move, and be convenient to installation and processing, reduced cost of manufacture.Because adopt the structure of steel ball with scale body and base flexible connection, after the scale body bore side force, steel ball can roll in upper and lower steel bowl; be easy to the steel ball automatic capturing; make the scale body be easy to reset to original state, and sensor is protected, be not subjected to the impact of side force.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view that Fig. 1 removes table top.
Fig. 3 is the I place structure for amplifying synoptic diagram of Fig. 1.
Embodiment
Four-sensor weighing platform as shown in Figure 1 comprises base 8, is installed in sensor 6, scale body 7 and table top 2 on the base 8, and the instrument that is contained on the column 1 is connected with the sensor 6 of weighing platform by the sensor electrical cable, and adjustable scale pin 9 is equipped with in weighing platform base 8 bottoms.Scale body 7 is the rigid frame structure, and rigid frame as shown in Figure 2 is " day " font structure; It perhaps is the sphere of movements for the elephants type; Or be
Font structure can adopt channel-section steel or bar steel to do, and therefore can reduce the scale body thickness, alleviates weighing platform weight, has both made things convenient for processing and fabricating simultaneously, is convenient to large-scale production again.Four jiaos of symmetries at base 8 are fitted with four sensors 6, and every sensor 6 tops are connected with lower steel bowl 5, and the bottom of scale body 7 is connected with upper steel bowl 3, flexibly connect by steel ball 4 between the upper and lower steel bowl 3,5, and the upper and lower steel bowl 3,5 that is connected with steel ball 4 has at least one to be to have sphere, or is sphere simultaneously; Preferably as shown in Figure 3, upper steel bowl 3 is a flute profile, and lower steel bowl 5 has sphere; Can also be that upper steel bowl 3 has sphere, and lower steel bowl 5 flute profiles, like this can be to 4 certain position-limiting actions of steel ball.Table top 2 contacts with the rigidity of scale body 7 when weighing for minimizing, and the top of scale body 7 is connected with flexible pad 10.
Weighing platform of the present utility model is provided with four sensors at four jiaos, has changed the force way of traditional weighing platform, has therefore improved weighing platform anti-bias load ability, can further reduce the weighing platform cost of manufacture.
