Abstract
The utility model relates to a double-pin rotation-prevention connecting piece of a column type weighing sensor, in particular to a connecting piece for installing a column type weighing sensor, mainly aiming at solving the problem of rotation of the column type weighing sensor. The double-pin rotation-prevention connecting piece comprises a base and a compression ring and is characterized in that a blind hole is arranged at the central position of the upper surface of the base, and two sides of the blind hole are symmetrically provided with two bolt holes; the lower surface of the base is symmetrically provided with two pin holes which are internally provided with rotation-prevention pins, the axis of the pin holes is vertical to that of the bolt holes, the pin holes are blind holes, and the bottoms of the pin holes are intersected with the blind hole in the upper surface of the base; the bottom of the base is provided with a circle of boss; and the base and the compression ring are fixed on a bottom plate through bolts. The column type sensor is prevented from rotating due to the shaking of a loader, and an O-shaped sealing ring plays a role of protecting the column type weighing sensor, thus improving the reliability of the column type sensor.
Description
Technical field
The utility model relates to a kind of installation coupling of pillar LOAD CELLS, the anti-rotation web member of specifically a kind of double-pin of pillar LOAD CELLS.
Background technology
The pillar LOAD CELLS is used increasingly extensive, expose the shortcoming of pillar LOAD CELLS gradually, it is the rotation that rocking of weighing apparatus brought the pillar LOAD CELLS, when especially truck scale measures canned liquid, liquid is difficult for stable, the multi-direction of weighing apparatus carrier rocks, cause the pillar LOAD CELLS slowly to be rotated, along with the column type sensor rotation, cable on it just is wrapped on the shell of sensor, very easily cable is dragged disconnectedly, the araeosystyle sensor has caused damage, has also influenced gage work simultaneously.Weighing apparatus manufacturing firm and user will be affected and lose like this.
Though some anti-rotation structures are arranged at present, all unreliable or cost is higher.As single pin anti-rotation structure, promptly use a pin or a screw to place in the groove of column type sensor bottom, this structure is on stressed bigger weighing apparatus, and carrier is out of shape under the big situation, very easily destroys stop pin or anti-turn screw.For another example, be processed into hexagon at the lower cylindrical face of column type sensor, also process the hexagon blind hole on the base, the hexagon of sensor bottom is put into the hexagon blind hole, the anti-rotation of this structure, complex process cost height.
The utility model content
The purpose of this utility model is to provide a kind of anti-rotation web member of double-pin of pillar LOAD CELLS, solves the problem of the rotation of pillar LOAD CELLS.
The technical scheme that its technical matters that solves the utility model adopts is: the anti-rotation web member of the double-pin of pillar LOAD CELLS, comprise base and pressure ring, it is characterized in that described base upper surface center is provided with a blind hole, the blind hole symmetria bilateralis is provided with two bolts hole; The lower surface of base is arranged with two pin-and-holes, built-in stop pin, and the axis of pin-and-hole and the axis of bolt hole are perpendicular, and described pin-and-hole is a blind hole, and the pin-and-hole bottom is crossing with the blind hole of base upper surface; The bottom of base is provided with a circle boss; Described base and pressure ring are by being bolted on the base plate; Described pressure ring inboard is provided with the groove that matches with base boss, and the pressure ring both sides are respectively equipped with bolt hole; The inwall of described blind hole is provided with a circle seal groove, is provided with O-ring seals in the seal groove; Described stop pin and pillar LOAD CELLS form clearance fit.
The beneficial effects of the utility model are: stoped the column type sensor rotation that brings because of rocking of carrier, O-ring seals araeosystyle LOAD CELLS has played protective effect, has improved the reliability of column type sensor.
Description of drawings
Fig. 1 is a front view of the present utility model,
Fig. 2 is the cross section view of the utility model A-A.
Among the figure: 1 base, 2 pressure rings, 3 stop pins, 4 blind holes, 5 boss, 6 grooves, 7 seal grooves, 8O shape O-ring seal, 9 pillar LOAD CELLS, 10 base plates, 11 pin-and-holes.
Embodiment
As Fig. 1, shown in Figure 2, the anti-rotation web member of the double-pin of pillar LOAD CELLS comprises base 1, pressure ring 2 and base plate 10, and described base 1 upper surface center is provided with a blind hole 4, and blind hole 4 symmetria bilateralis are provided with two bolts hole; The lower surface of base 1 is arranged with two pin-and-holes 11, built-in stop pin 3, and the axis of pin-and-hole 11 and the axis of bolt hole are perpendicular, and described pin-and-hole 11 is a blind hole, and the blind hole 4 of pin-and-hole 11 bottoms and base 1 upper surface intersects; The bottom of base 1 is provided with a circle boss 5; Described pressure ring 2 inboards are provided with the groove 6 that matches with base 1 boss 5, and pressure ring 2 both sides are respectively equipped with bolt hole, and base 1 and pressure ring 2 are by being bolted on the base plate 10; The inwall of described blind hole 4 is provided with a circle seal groove 7, is provided with O-ring seals 8 in the seal groove 7; Described stop pin 3 forms clearance fit with pillar LOAD CELLS 9.
During work; because of rocking of carrier causes 9 rotations of pillar LOAD CELLS; at this moment; the groove 6 of pillar LOAD CELLS 9 bottoms and two stop pin 3 resistances have stoped the rotation of pillar LOAD CELLS 9, if turning moment is bigger; by two bolts on the base 1 base 1 is connected with base plate 10; guaranteed not produce rotation between base 1 and the base plate 10, pressure ring 2 promptly is fixed together base 1 and base plate 10 by bolt simultaneously, again base 1 has been played location and protective effect.Base plate 10 in use is built on the rock with the installation of pillar LOAD CELLS and is connected, and has so just stoped the rotation of pillar LOAD CELLS fully, has improved the reliability of column type sensor.
