Description
Technical field
The utility model relates to a kind of sensor, more specifically to a kind of double-shear beam sensor.
Background technology
At present, the double-shear beam sensor is widely used in all kinds of electronic-weighing equipment such as electronic vehicle weighing apparatus, vapour inspection line, track scale as LOAD CELLS, and the most employing of existing double-shear beam sensor is the two-end fixed beam structure; Because the border rigidity of this structural requirement sensor is big, make that therefore sensor construction is complicated, build also increases thereupon; And then make and install inconveniently, not meeting now the miniaturization of weighing-appliance and integrated requirement, the Chinese patent notification number is CN201196586Y; The day for announcing is that the utility model name on February 18th, 2009 is called double-shear beam type LOAD CELLS; Include base, be connected in elastic body on the base, be attached to strainometer on the elastic body, be positioned at the steel ball of elastic body upper end and prevent the pressure bearing head on steel ball, it is characterized in that, said elastic body is through preventing that two cylinders on said base are as support; Elastic body is connected with base through bolt and elastic washer; It is parallel that the axis of said cylinder and elastic body get width, owing to adopted the supporting construction of both-end tube, reduced the height of sensor; Make it have shock proof ability; But the weighing precision of LOAD CELLS is still accurate inadequately, and has increased cylinder as support, has increased manufacture difficulty and cost.
Summary of the invention
The purpose of the utility model is that to overcome double-shear beam sensor weighing precision not accurate enough, and the technical barrier that processing is inconvenient provides a kind of simple in structure, easy for installation, the double-shear beam sensor that weighing precision is high.
The utility model solves through following technical proposals: a kind of double-shear beam sensor; Comprise elastic body, big foil gauge and cable; Described cable is connected with an elastomeric end, and described elastic body is rectangular-shaped, and the middle of elastic body upper surface is provided with breach; Elastomeric two sides all are pasted with big foil gauge, and elastomeric two ends are provided with and the big parallel bolt hole of foil gauge.The elastic body that is rectangular parallelepiped can better cooperate with weighing-appliance; Simultaneously the breach on the elastic body increased and weighing-appliance between compression area, improve the transmission capacity of power, through cooperating more closely with weighing-appliance and increasing compression area; Improved the area of big foil gauge simultaneously; Not only simple in structure, easy for installation, but also improved weighing precision.
As preferably, described big foil gauge has two, and two big foil gauges are positioned at the both sides of breach.Breach can more directly effectively be accepted pressure as stress point near the big foil gauge of breach, improves weighing precision.
As preferably, described elastic body lower surface middle is provided with convexity.When installing, play the effect of overload protection with weighing-appliance is supporting.
As preferably, described cable is connected with elastic body through water joint.Water joint can play waterproof effect.
As preferably, described breach is dumbbell shaped.Increase elastomeric compression area, made the pressure that receives near big foil gauge place bigger simultaneously, and then improved weighing precision.
Therefore, a kind of double-shear beam sensor of the utility model possesses following beneficial effect, 1, simple in structure; Processing, easy for installation, 2, the elastic body that is rectangle can better cooperate with weighing-appliance; Simultaneously the breach on the elastic body increased and weighing-appliance between compression area, improve the transmission capacity of power, through cooperating more closely with weighing-appliance and increasing compression area; Improve the area of big foil gauge simultaneously, improved weighing precision.

Fig. 2 is a kind of vertical view of Fig. 1.
The 1-elastic body, the big foil gauge of 2-, the 3-cable, the 4-water joint, the 5-bolt hole, 6-is protruding.
Specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: like Fig. 1, shown in Figure 2, a kind of double-shear beam sensor comprises elastic body 1, big foil gauge 2 and cable 3; Elastic body 1 is rectangular parallelepiped, matches with weighing-appliance, has breach in the upper end face middle of elastic body 1; Breach is dumbbell shaped, all is pasted with big foil gauge 2 in the two sides, front and back of elastic body 1, and each side all is pasted with two big foil gauges 2; Two big foil gauges 2 are positioned at the both sides of breach, and are big near the breach area at big foil gauge 2 places, improved the pressure of weight to the breach both sides; Simultaneously also increase big foil gauge 2 areas, and then increased the lifting surface area of big foil gauge 2, improved the pressure that big foil gauge 2 receives; Thereby the raising weighing precision, middle is made with convexity 6 in the lower surface of elastic body 1, when double-shear beam sensor and the supporting use of weighing-appliance, plays the effect of overload protection.Middle has a bolt hole 5 at the two ends of elastic body 1, is fixedly connected with weighing-appliance through bolt hole 5, and cable 3 is connected with an end of elastic body 1 through water joint 4, and water joint 4 can play waterproof, anti-wet goods effect.
Weight exert pressure with elastic body 1 on indentation, there; Because elastic body 1 has deformability, deformation takes place, and then make 2 of big strains that are attached on the elastic body 1 also receive deformation pressure; Big foil gauge 2 just can draw weight of heavy through converting pressure into electric weight through calculating electric weight.And big foil gauge is near more apart from breach, and the amplitude of elastic body deformation is big more, and the deformation pressure that big foil gauge receives is just big more, and weighing precision is just accurate more.
