Further, support frame as described above includes pedestal and the supporting rod that is vertically set on pedestal.
Further, the horizontal part is level tray, and the level tray is arranged in the upper end of supporting rod.
Further, it is in horizontal position before overturning and after overturning to ensure to strain load cell, it is described to answer
Become load cell and be connected with cantilever, the cantilever is articulated with the upper end of support frame as described above by shaft, in this way it can be ensured that cantilever
It is most of before overturning and overturning rear support is on level tray so that strainable load cell is before overturning and turns over
It is horizontal after turning.
Further, the supporter includes the first pallet, the second pallet and is arranged in the first pallet and the second pallet
Between connecting rod.
Further, first pallet is parallel to the second pallet, and the connecting rod is vertically connected on the first pallet and
Between two pallets；First pallet is arranged at the dynamometry of strain load cell；
Further, the connecting rod is arranged at the center of the first pallet and the second pallet, further, described

Fig. 2 is embodiment schematic diagram of the utility model under tension measurement pattern；
In figure：1, pedestal, 2, supporting rod, 3, level tray, 4, shaft, 40, clamp spring, 5, cantilever, 6, strain force-measuring sensing
Device, 60, jack-plug socket, 7, supporter, the 70, first pallet, 71, connecting rod, the 72, second pallet, 8, loaded member.
Specific implementation mode
The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
The utility model discloses a kind of strain load cell experiment instrument, including supporting rack, the upper ends of support frame as described above
Equipped with horizontal part, the part that support frame as described above stretches out horizontal part is hinged with and the strain dynamometry of 180 ° of overturnings can be passed in perpendicular
Sensor 6, the strain load cell 6 are equipped with the supporter 7 loaded for loaded member 8；The supporter 7 is by the first pallet
70, connecting rod 71, the second pallet 72 are constituted, and the first pallet 70 is arranged in parallel with the second pallet 72, is connected to by connecting rod 71
Together.
As a kind of specific embodiment, support frame as described above can be by pedestal 1 and the supporting rod being vertically set on pedestal 12
It constitutes, pedestal 1 is horizontally disposed；The horizontal part can be a level tray 3, parallel with the pedestal 1, level tray
3 are arranged in the upper end of supporting rod 2, and supporting rod 2 is more than that the part of level tray 3 passes through 4 articulating boom 5 of shaft, the both ends of shaft 4
It is fixed by clamp spring 40；The length of cantilever 5 should be greater than the radius of level tray 3, so that cantilever 5 extends to level tray
3 is outer to be connect with strain load cell 6.If so, strain load cell 6 is before overturning and after overturning, cantilever 5 is most of
It is supported on level tray 3, so that strain load cell 6 is in horizontal position before overturning and after overturning.
Specifically, Fig. 1 shows the state diagram before the utility model overturning, that is to say the pressure measurement state of this experiment instrument
Figure, the first pallet 70 are arranged at the force-detecting position of strain load cell 6, since cantilever 5 is in horizontality, at this time first
Pallet 7 is in horizontality, and loaded member 8 is placed on the first pallet 70, and strain load cell 6 is sensed as pressure test
Device exports the electric signal of generation by jack-plug socket 60 outward.In order to match with the supporter 7, the load
8 preferred sliding weight of steelyard of part.Connecting rod 71 not only acts as the effect for connecting the first pallet 70 with the second pallet 72, also acts as a limit
Effect, connecting rod 71 can assist sliding weight of steelyard close to center place, prevent centre-of gravity shift, it is ensured that the overall stability of the experiment instrument.
State diagram after being overturn Fig. 2 shows the utility model, that is to say the tension measurement state diagram of this experiment instrument, will hang
Arm 5 overturns 180 ° along shaft 4, that is, is changed to tensile test state, and supporter 7 also forms one 180 ° of overturning at this time, and first
The former weight-bearing surface of pallet 70, connecting rod 71 are used as sunpender, the second pallet 72 are hung, the sliding weight of steelyard of test is put in the second support at this time
On disk 72, you can the electric signal that strain load cell 6 is used as to tensile test sensor by jack-plug socket 60 exports outward.
Above-described embodiment is the preferred embodiment of the utility model, is not the limitation to this practical technique scheme, only
If without the technical solution that creative work can be realized on the basis of the above embodiments, it is regarded as falling into this practicality
In the rights protection scope of new patent.
