Characteristics of the present utility model are to have set up to carry out spacing position-limit mechanism to connecting rod 15, this position-limit mechanism comprises at least one baffle plate, at least one baffle plate from the side of connecting rod 15 and/or the outside block connecting rod and and connecting rod between leave the gap, position-limit mechanism is fixed on housing or enclosure interior.In practical operation, this position-limit mechanism can adopt multiple scheme: the first only adopts a baffle plate, and this baffle plate can keep off any one side or the outside at connecting rod; It two is to adopt two baffle plates 191,192 (referring to Fig. 2), and two baffle plates 191,192 are kept off both sides or one of them side and the outside at connecting rod respectively; It three is to adopt three baffle plates 191,192,193 (referring to Fig. 2, Fig. 3), two both sides that baffle plate 191,192 keeps off respectively at connecting rod wherein, and the 3rd baffle plate 193 retaining are in the outside of connecting rod; It four is to connect to form the U-shaped baffle plate by three baffle plates, this U-shaped baffle plate is kept off on connecting rod simultaneously from the both sides of connecting rod and the outside connecting rod is carried out the spacing of the spacing of left and right directions displacement and above-below direction displacement.
The utility model connecting rod vibration pointer type SF 6The action principle of gas density relay is based on flexible member C shape pipe 6, utilizes the pressure and temperature of 7 pairs of variations of temperature-compensating sheet to revise, reaction SF 6The variation of gas density.Promptly at measured medium SF 6Under the pressure effect of gas, because the effect of temperature-compensating sheet 7 has been arranged, the variation of its density value, force value also changes accordingly, force the end of C shape pipe 6 to produce corresponding strain-displacement,, pass to movement 2 by means of temperature-compensating sheet 7 and connecting rod 15, movement 2 passes to pointer 5 again, satisfies tested SF 6The gas density value indicates on dial.Density monitor just can be SF like this 6Density value has shown.If leaked gas, its density value drops to a certain degree (reach and report to the police or the locking value), C shape pipe 6 produces accordingly to bottom offset, by temperature-compensating sheet 7, make crossbeam 16 to bottom offset, adjusting rod 141,142,143 on the crossbeam 16 just promotes corresponding sensitive switch 91,92,93 contacts and connects, and sends corresponding signal (reporting to the police or locking), reaches the SF in the equipment such as supervision and control electric switch 6Gas density makes the electric equipment trouble free service.If its density value has raise, force value also raises accordingly, be elevated to a certain degree, C shape pipe 6 also produces accordingly to top offset, by temperature-compensating sheet 7, makes crossbeam 16 to top offset, adjusting rod 141,142,143 on the crossbeam 16 is just to top offset, adjusting rod 141,142,143 is just away from sensitive switch 91,92,93, and its contact just disconnects, and signal (reporting to the police or locking) is just removed.So just finish the function of density monitor.
Because the utility model connecting rod vibration pointer type SF 6The signal contact of gas density relay adopts the sensitive switch form, moreover the control of sensitive switch contact is all controlled by adjusting rod, and the control of adjusting rod is carried out by compensating plate 7 and C shape pipe 6, compensating plate 7 generally is not afraid of vibration, it only changes with variation of temperature, and the power of C shape pipe is bigger, and resistance to shock is better, is difficult for being out of shape or producing displacement because of vibration.The most important thing is, in order to increase resistance to shock, the utility model has increased the connecting rod position-limit mechanism, purpose is when the switch divide-shut brake produces vibration, prevents that crossbeam from axially or radially producing undue displacement, even crossbeam axially or radially is being shifted, also can be connected bar position-limit mechanism retaining in a fixing controllable scope, can prevent that adjusting rod from blocking or breaking away from the phenomenon of sensitive switch, guarantee system's reliably working, so just improve the resistance to shock of this product greatly.In addition, SF 6After the density value of gas descended, C shape pipe 6 just moved down, and until the action of signal (reporting to the police or locking) contact, promptly the sensitive switch contact is connected.Density value descends more, and it is firm more that sensitive switch is just connected, and descends again, C shape pipe 6 plate 11 that just is positioned is positioned on its scale value, and at this moment, C shape pipe 6 is used on the sensitive switch with bigger masterpiece, sensitive switch is under the good pressure and in the good connection, is not afraid of vibration.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.Also can be fixed on the top (being other direction) of adjusting rod as sensitive switch.
