The lower part of the L-shaped connecting bracket 40 is connected with the upper part of the rotary speed reducer 70, the working platform 20 is fixed on the bracket 10, due to the unstable characteristic of the parallelogram structure, the positioning piece 11 can be pressed on the thimble screw 51 by the self weight and the load of the working platform 20 and the bracket 10, the upper part of the thimble screw 51 is spherical, the positioning piece 11 is always in point contact with the thimble screw, and thus the weighing precision of the weighing body 30 cannot be influenced even if the bracket 10 has certain deflection.
In the embodiment of the present invention, the top support member is a thimble screw 51, the adjusting member is an adjusting nut 52 in threaded fit with the thimble screw 51, a threaded hole is formed in the weighing body 30, and the adjusting nut 52 can be used for adjusting the height of the thimble screw 51 extending out of the threaded hole along the vertical direction, wherein the weighing body 30 is a weighing sensor body capable of sensing the weight transferred by the top support assembly 50.
Specifically, the thimble screw 51 is screwed tightly in the threaded hole of the weighing body 30 through threaded connection, and the position of the thimble screw 51 is fixed by the adjusting nut 52; meanwhile, when the height of the thimble screw 51 extending out of the weighing body 30 needs to be adjusted, the adjusting nut 52 is directly loosened, and the thimble screw 51 can move up and down in the threaded hole. The top end of the thimble screw 51 has a spherical structure protruding toward the spacer 11, and since the spacer 11 is a horizontally extending plate-shaped structure, this structure can achieve a mode in which the top of the thimble screw 51 and the plate-shaped spacer 11 are always in point contact abutment. When the work platform is in operation, the weight of the bracket 10 and the work platform 20 is transmitted to the thimble screws 51 through the positioning members 11 in a pressing manner to press the thimble screws 51, so that the weighing body 30 can sense the pressure applied to the thimble screws 51 and convert the pressure into weight data for output. In addition, in order to make things convenient for operating personnel maintenance and dismantlement, with adopting between setting element 11 and the bracket 10 and dismantling the connected mode, and the one end that L type linking bridge 40 was kept away from to setting element 11 extends out from the bracket 10 in, when setting element 11 damaged or need change, direct follow the outside of bracket 10 tear down setting element 11 can, simple and convenient.
Further, the L-shaped connecting bracket 40 includes a horizontal plate 41 extending along the horizontal direction and a vertical plate 42 extending along the vertical direction, the vertical plate 42 is disposed closely to the outer side of the bracket 10, the horizontal plate 41 is detachably connected with the rotary speed reducer 70, and the rotary speed reducer 70 is located below the working platform 20 at intervals.
