Abstract
The utility model relates to an elastic body of a weighing sensor, belonging to the technical field of an electronic weighing apparatus. The elastic body comprises a body, connecting screw holes, strain beams and a deformed slot, wherein the connecting screw holes are arranged at both ends of the body; the deformed slot is arranged between the two strain beams and consists of a long slot and two independent through holes; communicated and isometric notches are respectively arranged between the long slot and the two through holes; and the clearance of the notch (delta) is 0.1-0.3mm. Through theimprovement of the deformed slot, the two communicated and isometric notches are arranged between the long slot and the two through holes, so that one clearance is formed through the two notches forprotecting the elastic body, the structure is simple, any parts are not necessarily increased, and the elastic body is applicable to the small-sized weighing sensor for fast weighing on dynamic occasions.
Description
Technical field
The utility model relates to a kind of elastic body of LOAD CELLS, belongs to the electronic scale technical field.
Background technology
Therefore influences such as under the dynamic case, LOAD CELLS can be subjected to more vibration, impact, push and reverse have higher requirement to the autoprotection of LOAD CELLS.The LOAD CELLS strain beam of low capacity is thinner, just easier damage under this dynamic environment.Easily cause LOAD CELLS to damage under the dynamic situation for solving, can limit elastomeric deflection, reduce the distortion after elastic body impacts, can realize the protection of weighing under dynamic by the bearing pin that is installed on the elastic body.But said structure can not be applicable to the LOAD CELLS that size is littler.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, can realize the elastic body of the LOAD CELLS of the dynamic safeguard protection of weighing down.
The utility model is that the technical scheme that achieves the above object is: a kind of elastic body of LOAD CELLS, comprise body, be arranged on connection screw, strain beam and the distortion slotted eye between two strain beams at body two ends, it is characterized in that: described distortion slotted eye by long slot bore and two independently through hole constitute, long slot bore has and communicates and equidistant notch respectively with between two through holes, and the notch gap delta is at 0.1～0.3mm.
The elastomeric distortion slotted eye of the utility model by a long slot bore and two independently through hole constitute; because long slot bore has with two through holes and communicates and equidistant two notches; therefore can form the gap that elastic body is protected by these two notches; simple in structure; need not to increase any part; when elastic body affords up or down power from vertical direction; can limit elastomeric deflection by notch; reduce the distortion after elastic body is subjected to vertical impact; the safeguard protection of weighing under realizing dynamically is applicable to the rapid weighing metering of the less LOAD CELLS of some sizes under dynamic case.
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 A-A sectional structure synoptic diagram of Fig. 1.
Wherein: the 1-body, 2-connects screw, 3-long slot bore, 4-strain beam, 5-notch, 6-through hole.
Embodiment
See shown in Fig. 1,2, the elastic body of the utility model LOAD CELLS, comprise body 1, be arranged on connection screw 2, strain beam 4 and the distortion slotted eye between two strain beams at body 1 two ends, an elastomeric end is connected with support by securing member, and the elastomeric other end is connected with the scale pan.See shown in Figure 1; distortion slotted eye of the present utility model by long slot bore 3 and two independently through hole 6 constitute; through hole 6 can be circular hole or mounting hole; long slot bore 3 has and communicates and equidistant notch 5 respectively with between two through holes 6; and the gap delta of notch 5 is at 0.1～0.3mm; foil gauge is separately fixed at long slot bore 3 two ends and through hole 6 is positioned at strain beam 4 one sides; when surpassing, the load of vertical direction limits load; then elastic body deforms; and then the upper and lower surfaces contact of this notch 5 is protected elastic body, realize the safeguard protection of dynamically weighing down.
Claims (2)
1, a kind of elastic body of LOAD CELLS, comprise body (1), be arranged on connection screw (2), strain beam (4) and the distortion slotted eye between two strain beams at body (1) two ends, it is characterized in that: described distortion slotted eye by long slot bore (3) and two independently through hole (6) constitute, long slot bore (3) has and communicates and equidistant notch (5) respectively with between two through holes (6), and the gap delta of notch (5) is at 0.1～0.3mm.
2, according to the elastic body of the described LOAD CELLS of claim 1, it is characterized in that: described through hole (6) is circular hole or mounting hole.
