Abstract
The utility model discloses a sensor used for electronic platform scale, which is a biplate twin beam type high sensitivity sensor, comprising an elastomer, a steel ball seat and a steel ball, the elastomer is provided with an elastic sheet, the steel ball seat is positioned in the elastic sheet, the steel ball is positioned on the steel ball seat. The utility model sensor has the advantages of simple structure, high sensitivity, small measurement error and low cost.
Description
[technical field]
The utility model relates to a kind of sensor, refers in particular to a kind of steel part sensor that is applied to electronic platform scale.
[background technology]
The sensor that existing electronic platform scale adopted generally is single aluminum component sensor, its precision is relatively low, measuring error is bigger, and single aluminum component sensor is installed in electronic platform scale and is not easy to realize sealing and waterproof, and support need be set, promptly electronic platform scale need be taked double-decker, and is comparatively complicated, make the bulky heaviness of electronic platform scale, cost is higher.
Therefore, provide a kind of simple in structure, highly sensitive, measuring error is little, lower-cost sensor is real in necessary.
[summary of the invention]
The purpose of this utility model provide a kind of simple in structure, highly sensitive, measuring error is little, lower-cost sensor.
To achieve these goals, the utility model adopts following technical scheme:
A kind of sensor that is applied to electronic platform scale is provided, and it is a biplate two-beam type high sensor, and it comprises elastic body, steel ball seat and steel ball, and this elastic body is provided with flexure strip, and steel ball seat places flexure strip, and this steel ball places on the steel ball seat.
Offer first Baltimore groove and second Baltimore groove on this elastic body, this first Baltimore groove relative with the second Baltimore groove opening to, and second Baltimore groove than first Baltimore groove little and its be located in the first Baltimore groove scope.
First Baltimore groove that this is offered in opposite directions and second Baltimore groove have formed two flexure strips on elastic body, comprise first flexure strip that is connected with elastomeric body, and second flexure strip that is connected with the first flexure strip body, this steel ball seat and steel ball place on second flexure strip.
Because second Baltimore groove is to be located in the first Baltimore groove scope, therefore second flexure strip that forms is to be on the first flexure strip body, second flexure strip can be fully with resilient movement about first flexure strip, and also resilient movement up and down of second flexure strip itself, and this first flexure strip and body junction are formed with two elastic beams, this steel ball seat and steel ball place in the middle of second flexure strip, so form a kind of biplate two-beam type sensor, on two elastic beams foil gauge is installed, existing single-beam list foil gauge sensitivity, stressed more even, reaction signal more comprehensively, the slight pressure that steel ball is sensed all can be by the exaggerative reaction of the displacement deformation of second flexure strip and first flexure strip, and sensitivity is very high, and Stability Analysis of Structures is reliable.
The range of this sensor can reach 100 kilograms, and it can be installed on the electronic platform scale by riveted joint, need not double-deck weighting platform structure, simplifies the electronic platform scale structure, and saves cost.
Compared with prior art, the utility model has following beneficial effect:
Sensor of the present utility model has the biplate twin-spar construction, on two elastic beams foil gauge is installed, and is stressed more even, and reaction signal more comprehensively, and is simple in structure, highly sensitive, measuring error is little, cost is lower.

Fig. 1 is the synoptic diagram of the utility model sensor;
Fig. 2 is the A-A cross section view of Fig. 1;
Fig. 3 is the stereographic map of the utility model sensor.
[embodiment]
Please refer to Fig. 1～3, the utility model sensor is a biplate two-beam type high sensor, and it comprises elastic body 1, steel ball seat 2 and steel ball 3, and this elastic body 1 is provided with flexure strip, and steel ball seat 2 places flexure strip, and this steel ball 3 places on the steel ball seat 2.
Offer first Baltimore groove 11 and second Baltimore groove 12 on this elastic body 1, this first Baltimore groove 11 relative with second Baltimore groove, 12 openings to, and second Baltimore groove, 12 to the first Baltimore grooves 11 are little and it is located in first Baltimore groove, 11 scopes.
First Baltimore groove 11 and second Baltimore groove 12 that this is offered have in opposite directions formed two flexure strips on elastic body 1, comprise first flexure strip 13 that is connected with elastic body 1 body, and second flexure strip 14 that is connected with first flexure strip, 13 bodies, this steel ball seat 2 and steel ball 3 place in the middle of second flexure strip 14.
The opening of this second Baltimore groove 12 can be about half size of first Baltimore groove 11, and the length of this second flexure strip 14 can be about half of first flexure strip 13, to form the biplate twin beams form of high sensitivity reaction.
The above only is preferred embodiment of the present utility model, and protection domain of the present utility model is not limited thereto, and those of skill in the art are any to be included within the utility model protection domain based on non-material change on the technical solutions of the utility model.
