Abstract
The present utility model relates to a weighting sensor, concretely to a cross beam weighing sensor. The sensor is provided to overcome the technical problems of the prior weighing sensor that when the four-way side forces of a heavy object are acted on the weighing sensor, the bearing of an elastic body is uneven, thus the service life of the weighing sensor is influenced, and the weighing sensor is easily damaged in the overloading situation. By adopting the cross beam weighing sensor, the phenomenon that the elastic body is damaged due to the long time four-way side forces can be effectively avoided, and overload protection can be realized. The cross beam weighing sensor comprises an elastic body, a pedestal and a cable, the lower end face of the elastic body is connected with the upper end face of the pedestal, and the cable is connected with the elastic body. The cross beam weighing sensor is characterized in that the elastic body is of a cross beam structure, the diameter of the elastic body is the same as that of the pedestal, recesses are arranged on the two side surfaces of each arm of the cross beam, foil gauges are attached on the recesses, and a bearing part is arranged on the center of the upper end face of the elastic body.
Description
Technical field
The utility model relates to a kind of LOAD CELLS, more specifically to a kind of rood beam LOAD CELLS.
Technical background
At present; LOAD CELLS is widely used in all kinds of electronic-weighing equipment such as electronic vehicle weighing apparatus, vapour inspection line, track scale, and it converts measurable electric signal into through the quality signal with weight, and now the most frequently used be exactly resistance strain weighing transducer; Elastic body deforms under the effect of external force; Make attaching foil gauge above that also in company with deforming, its resistance of foil gauge distortion back changes, and converts changes in resistance into electric signal at last.The Chinese patent notification number is CN201765036U; The day for announcing is that the utility model name on March 16th, 2011 is called novel LOAD CELLS; Comprise the ball bowl, connect spheroid and tough gonosome; The spacing swing of said tough gonosome be installed in one be used to support land the version upper surface; The structure that spacing swing is installed is: two ends, the bottom surface symmetry of tough gonosome is made two grooves, and the inner edge of two grooves is crimped on two homoaxial cylindrical rollers outer rim tops respectively, and the outer rim bottom of these two cylindrical rollers is crimped on lands in edition groove that the upper surface contraposition is made.Though above-mentioned utility model has reduced the center of gravity of claiming body, be difficult for body of one who has dropped dead by the roadside, be between each parts and be flexible coupling, single-piece is changed; Install, mobile convenient, but in actual use, the pressure of weight acts on the tough gonosome; Tough gonosome receives the four-way side force for a long time, influences the serviceable life of tough gonosome, and then the LOAD CELLS reliability is reduced, and does not also have overcurrent protection structure simultaneously; In case the LOAD CELLS overload will be damaged, and have potential safety hazard.
Summary of the invention
The purpose of the utility model is to overcome existing LOAD CELLS when receiving the four-way side force of weight; Make the elastic body unbalance stress; And then influence serviceable life of LOAD CELLS; The easy impaired technical barrier of LOAD CELLS under overload situations provides a kind of and can effectively avoid the phenomenon of elastic body because of damaged by the four-way side force simultaneously, can also play the rood beam LOAD CELLS of overload protective function simultaneously.
The utility model solves through following technical proposals: a kind of rood beam LOAD CELLS; Comprise elastic body, base and cable, described elastomeric lower surface is connected with the upper surface of base, and described cable is connected with elastic body; It is characterized in that; Described elastic body is the cross-bar structure, described elastic body and base diameter equal and opposite in direction, and two of each arm sides are equipped with depression on the cross-bar; Be pasted with foil gauge in the described depression, center, described elastic body upper surface is provided with bearing part.The utility model is simple in structure, and processing and fabricating is convenient, simple installation; And elastic body is orthogonal cross-bar; And elastomeric four walls can be evenly stressed, and the four-way side force influence that elastic body is received reduces greatly, has also played the effect of overload protection simultaneously.
As preferably, described bearing part upper surface is dome shape.The upper surface is curved bearing part and weighing-appliance has bigger contact area, improves the transmission capacity of power.
As preferably, edge, described base lower surface is provided with four bolts hole, and four bolts hole evenly distribute.Base can be fixedly connected with elastic body, and reliability is high, avoids elastic body shaking phenomenon when stressed, to occur.
As preferably, described cable is connected with elastic body through water joint.Can play waterproof, grease proofing effect.
Therefore, a kind of rood beam LOAD CELLS of the utility model possesses following beneficial effect, and 1, simple in structure, processing, easy for installation is fit to work under the various rugged surroundings.2, elastic body is orthogonal cross-bar, and four direction is all force-applied, and the four-way side force influence that elastic body is received reduces greatly, has also played the effect of overload protection simultaneously.

Embodiment
Pass through embodiment below, and combine accompanying drawing, it is bright specifically that the technical scheme of utility model is done a step.
Embodiment: like Fig. 1, shown in Figure 2, a kind of rood beam LOAD CELLS comprises elastic body 1, base 2 and cable 4; Elastic body 1 is orthogonal cross-bar, makes the four direction all can be evenly stressed, and then the four-way side force influence that elastic body 1 is received reduces greatly; Also played the effect of overload protection, two sides of each arm all have rounded depression on cross-bar simultaneously, and in depression, are pasted with foil gauge 7; Middle is made with bearing part 5 in the upper surface of elastic body 1, and the upper surface of bearing part 5 is dome shape, increases the contact area of bearing part 5 and weight; Improve the transmission capacity of pressure, the lower surface of elastic body 1 is fixedly connected with the upper surface of base 2, and base 2 is in the form of annular discs; Elastic body 1 equates with base 2 diameter; Have four bolts hole 6 (as shown in Figure 3) at the edge, lower surface of base 2, four bolts hole 6 evenly distribute, through bolt hole 6 can base 2 is firm fixing elastic body on; Avoid elastic body 1 shaking phenomenon when stressed, to occur, cable 4 is connected with elastic body through water joint 3.
Weight is exerted pressure on the bearing part 5 with elastic body 1; Bearing part 5 passes to elastic body 1 with pressure; Because elastic body 1 has deformability, deformation takes place, and then make the foil gauge 7 that is attached in the depression also receive deformation pressure; Foil gauge 7 just can draw weight of heavy through converting pressure into electric weight through calculating electric weight.
