Embodiment
The utility model embodiment is described in further detail below in conjunction with the accompanying drawings.
A kind of new digital weighing sensor, including fixed part 1, case 2 and connection annex 5, the fixed part 1 with
The pairing of case 2 forms the body structure of inner hollow, and overload protection portion 4, elastomer 6 are included inside the body structure and is answered
Become part 7, the strain part 7 is placed in elastomer 6 with being established among fixed part 1 and by installing screw with fixed part 1
Mechanically connect, the connection annex 5 includes sealing connector, and sealing connector is worn by the first avoid holes on case 2
Go out case 2.
Further, the fixed part 1 is surrounded by four the first mounting holes 9, and fixed part 1 passes through the first installation
Mechanical connection relation is established in hole 9 with fixed support.
Preferably, the specification of fixed part 1 is 220mm*80mm*12mm.
Preferably, the fixed part 1, case 2 and the height ratio of bearing part 3 are 1:6.15:3.35.
Further, the upper end of the elastomer 6 installation bearing part 3, the bearing part 3 passes through second on case 2
Avoid holes are mounted to an entirety with elastomer 6.
Further, the bearing part 3 is provided with two the second mounting holes 10, it is necessary to which the carrier of measurement passes through the second installation
Mechanical connection relation is established in hole 10 with bearing part 3.
Further, the overload protection portion 4 includes the first overload protection annex 11 and the second overload protection annex 12,
