Description
Technical field
The utility model relates to a kind of weighing apparatus, especially relates to a kind of LOAD CELLS.
Background technology
The large-tonnage weighing device mainly is made of several sections such as load bearing component, LOAD CELLS, chromacoders, and its core component is a LOAD CELLS.LOAD CELLS often has two kinds of pressure type and tensile force types, and the sensor that uses during general suspension hook claims is the tensile force type sensor, and the pulling force that sensor is subjected to by its upper and lower side makes its elastic body generation deformation experience the size of power, reaches the purpose of weighing.This type of traditional LOAD CELLS exists complex structure, machining precision and is difficult to guarantee, is subjected to the influence of load torsion easily and influences the precision of its weighing.The patent No. is that 200320109226.2 utility model discloses a kind of suspension hook and claims sensor special elastic body and suspension ring bindiny mechanism, its agent structure comprises elastic body, it is characterized in that elastic body is provided with connecting hole, suspension ring directly are connected with the elastomeric connecting hole of going up by bolt.This suspension hook claims sensor special elastic body and suspension ring bindiny mechanism.Suspension ring directly are connected with the elastomeric connecting hole of going up by bolt, and one-piece construction is simple, and manufacturing cost had both been saved in installation, easy to use.But the utility model still can not solve, and the precision that exists in the present technology is low, the technical matters of processed complex etc., so this technical scheme also has bigger room for improvement.
Summary of the invention
The utility model mainly is to solve low etc. the technical matters of existing in prior technology complex structure, installation and use inconvenience, precision, and a kind of simple in structure, easy for installation, technical scheme that precision is high is provided.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of U type LOAD CELLS, comprise elastic body, foil gauge and auxiliary circuit, it is characterized in that described elastomeric upper end is provided with a U-shaped connecting portion, elastomeric lower end is connected with " one " font connecting portion, the U-shaped connecting portion overlaps with the middle axial plane of " one " font connecting portion, both are equipped with axis and the described middle vertical connecting shaft hole of axial plane, elastomeric middle part is the deformation district, the both sides, front and back in deformation district are equipped with a symmetrical blind hole, are provided with foil gauge and auxiliary circuit thereof in the blind hole.The effect of U type connecting portion is it on the one hand in the weighing process, and the stress equalization on its both sides is difficult for the problem that button changes takes place, and can guarantee measuring accuracy; On the other hand, connected parts are put and its geometric center, and with " one " font connecting portion on same straight line, make its sensitivity of degree of proposing sensor to greatest extent.The U-shaped connecting portion with " once " design that overlaps of the middle axial plane of font connecting portion make two connecting portions processing as long as one-time positioning can finish, make it can improve its installation accuracy, also make sensor reduce the influence that is subjected to moment of torsion, to improve its accuracy of detection.
As preferably, the right side in described deformation district is provided with a wiring hole to be run through mutually with the blind hole of front side or rear side, and wiring hole is provided with fast interface.The external circuit of foil gauge and auxiliary circuit thereof links to each other with fast interface by blind hole, and fast interface can be so that it can easily and show with various corrections and equipment such as look and link to each other.
As preferably, described elastomer block left-right symmetric, the axis in described connecting shaft hole is located on the left-right symmetric face of elastomer block.Make and avoided moment of torsion that it is influenced in stressed direct center, improved its precision by elastomer block.
As preferably, described U-shaped connecting portion is equipped with chamfering with the place, diagonal angle of " one " font connecting portion.The effect of chamfering is to improve its security, after also can making it and other link linking to each other, can rotate comparatively freely.
The beneficial effect that brings of the present utility model is, solved low etc. the technical matters of existing in prior technology complex structure, installation and use inconvenience, precision, realized that suspension hook claims the features such as simple in structure, easy for installation, precision height with sensor.

Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of structural representations of the present utility model;
Accompanying drawing 3 is a kind of structural representations of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: accompanying drawing 1 is a kind of structural representation of the present utility model; Accompanying drawing 2 is a kind of structural representations of the present utility model; Accompanying drawing 3 is a kind of structural representations of the present utility model.The utility model is a kind of U type LOAD CELLS, it has a symmetrical elastic body, elastomeric two ends up and down are respectively equipped with a U type connecting portion 2 and " one " font connecting portion 3, middle axial plane on the horizontal longitudinal direction of U type connecting portion and " one " font connecting portion all overlaps, both are equipped with axis and the described middle vertical connecting shaft hole 21,31 of axial plane, elastomeric middle part is deformation district 1, the both sides, front and back in deformation district are equipped with a symmetrical blind hole 11, are provided with foil gauge and auxiliary circuit thereof in the blind hole.The right side in deformation district is provided with a wiring hole 12 to be run through mutually with the blind hole of front side or rear side, and wiring hole is provided with fast interface.The external circuit of foil gauge and auxiliary circuit thereof links to each other with fast interface by blind hole, and fast interface can be so that it can easily and show with various corrections and equipment such as look and link to each other.The U-shaped connecting portion is equipped with chamfering with the place, diagonal angle of " one " font connecting portion.
The effect of the U type connecting portion of this sensor is it on the one hand in hanging the title process, the stress equalization on its both sides, and the problem that is difficult for twisting can guarantee measuring accuracy; On the other hand, connected parts are put and its geometric center, and with " one " font connecting portion on same straight line, make it can improve the measuring accuracy of sensor to greatest extent.The U-shaped connecting portion with " once " design that overlaps of the middle axial plane of font connecting portion make two connecting portions processing as long as one-time positioning can finish, make it can improve its installation accuracy, also make sensor reduce the influence that is subjected to moment of torsion, to improve its accuracy of detection.
So characteristics such as the utility model is simple in structure, easy for installation, precision height are that suspension hook claims the improvement that once has certain meaning with the sensor aspect.
