As preferably, strain bore is a circular hole, and foil gauge adopts pasting on the medial surface of the strain bore left and right sides of two foil gauges symmetries.Get the accuracy of detection that distributing position can improve LOAD CELLS through this foil gauge.
As preferably; The end face of response body or bottom surface are provided with the line concentration hole coaxial with response body; The bottom surface of said each strain bore is provided with the routing hole that is connected with the line concentration hole; The said data line that is connected with each foil gauge passes routing hole and is intersected in line concentration hole place and joins each other in a bit, and the interface point place of each data line is connected with a data lines and exports to the response body outside.The data line that is connected with each strain bore all is arranged on response body inside and can effectively protects data line.
As preferably, the response body outer race is provided with a sheath; The height of sheath is less than the height of response body, and the upper surface of sheath is positioned at response body end face below, and the lower surface of sheath is positioned at top, response body bottom surface; The sheath medial surface is provided with first annular groove, and said response body is provided with second annular groove with respect to first annular groove on the side, is provided with O type circle between said sheath and the response body, and O type circle is positioned at first annular groove and the second annular groove place.The peripheral sheath that is provided with of response body can play a protective role to response body, makes the lateral force resistance of LOAD CELLS strong.Be connected through O type circle between sheath and the response body, be convenient to the dismounting and the installation of sheath, also be convenient to maintenance simultaneously.
As preferably, the sheath lateral surface is provided with terminal box, and terminal box one side is provided with water joint; Also be provided with a leadout hole that is connected with the line concentration hole on the said response body side relative with terminal box; Said data line one end passes water joint and leadout hole and is positioned at place, line concentration hole and is connected with the interface point of each data line.Water joint can play sealing function, improves the stability of LOAD CELLS.
The beneficial effect of the utility model is: measuring accuracy height, good stability, lateral force resistance are strong.
