A kind of preferable scheme, said moving contact web member are that the moving contact connection is colluded, and the moving contact connection is colluded and is similar " J " font.The moving contact web member can also adopt web members such as other snap close, and hooking structure is simple, easy to use but the moving contact web member of other structure all is not so good as the moving contact connection.
A kind of preferable scheme; Said force measuring machine comprises dynamometer, backstay, holder and stop collar, and dynamometer is placed on the backstay, and backstay is fixed on the holder; Stop collar is fixed on the backstay; And stop collar is set on the periphery of dynamometer, and the front end of dynamometer connects the moving contact connection and colludes, and the rear end of dynamometer connects driving mechanism.The force measuring machine of this structure is relatively simple for structure, be convenient to make and maintenance.
A kind of more excellent scheme; Said driving mechanism comprises handle, swivel nut and screw mandrel; Said holder is similar ", and two sidewalls that vertically extend and be parallel to each other of holder have through hole, and swivel nut is fixed on the holder; The rear end of screw mandrel connects handle, and the front end of screw mandrel passes the rear end that is connected dynamometer behind swivel nut and two through holes.
Drive dynamometer for fear of screw mandrel and rotate, said driving mechanism also comprises the ring that is rotatably connected, and the rear end of dynamometer is provided with the Dalian T-Ring, the rotating front end that is fixed on screw mandrel of ring that is rotatably connected, and the ring that is rotatably connected is connected with the Dalian T-Ring.
Rock for fear of the ring that is rotatably connected, the accuracy that influence is measured, the front end of said screw mandrel is provided with slidably cover, the bottom of slidably overlapping contact backstay, the rotating middle part of slidably overlapping front end face that is fixed on of ring is rotatably connected.
More excellent scheme, the front end of said dynamometer is provided with little abutment ring, and said little abutment ring connects the moving contact connection and colludes.
The utility model beneficial effect against existing technologies is; Can detect moving contact and contact situation with static contact; So that understand problems such as the instantaneous contact force of opening and closing lock, separating force, folding lock speed, contact be whether balanced and good, it is simple in structure, be easy to make, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the user mode reference diagram of preferred embodiment shown in Figure 1.
Embodiment
As shown in Figure 1, the high-tension switch cabinet contact pressure force measuring machine in this preferred embodiment comprises moving contact web member, force measuring machine and driving mechanism, and said moving contact web member connects force measuring machine, and force measuring machine connects driving mechanism.
Said moving contact web member is that the moving contact connection colludes 8, and the moving contact connection is colluded 8 and is similar " J " font.The moving contact web member can also adopt web members such as other snap close, and hooking structure is simple, easy to use but the moving contact web member of other structure all is not so good as the moving contact connection.
Said force measuring machine comprises dynamometer 6, backstay 12, holder 1 and stop collar 11; Backstay 12 is fixed on the holder 1; Dynamometer 6 is placed on the backstay 12, and stop collar 11 is fixed on the backstay 12, and stop collar 11 is set on the periphery of dynamometer 6; The front end of dynamometer 6 connects the moving contact connection and colludes 8, and the rear end of dynamometer connects driving mechanism.
Said driving mechanism comprises handle 2, swivel nut 14 and screw mandrel 3; Said holder 1 is similar "; 1 two sidewalls that vertically extend and be parallel to each other of holder have through hole; Swivel nut 14 is fixed on the holder 1, and the rear end of screw mandrel 3 connects handle 2, and the front end of screw mandrel 3 passes the rear end that is connected dynamometer 6 behind swivel nut 14 and two through holes.
The front end of said dynamometer 6 is provided with little abutment ring 7, and little abutment ring 7 connects the moving contact connection and colludes 8.
As shown in Figure 2, in the time of test, moving contact 9 closes a floodgate with static contact 10, and the moving contact connection is colluded 8 and caught on moving contact 9 then.Shake handle 2 at last, make screw mandrel 3 relative swivel nuts 14 move backward, pull back dynamometer 6, dynamometer 6 colludes 8 pulling contacts 9 through the moving contact connection, till moving contact 9 and static contact 10 are separated.At this moment, dynamometer 6 is just measured the size of the power that moving contact 9 and static contact 10 open a sluice gate.Through the power of opening a sluice gate, just can understand moving contact and contact situation with static contact.
