The invention relates to a shockproof dial SF6 gas density relay which comprises a base, a cross beam, at least one regulating lever, the micro switches which are set in pairs with the regulating levers and various operating arms which are installed on various micro switches. The invention is characterized in that the invention also comprises a reinforcing mechanism which reinforces the micro switches, namely, reinforces the housing for the micro switches, or a reinforcing mechanism which limits the operating arm of the micro switches and the regulating levers while the reinforcing mechanism reinforces the housing of the micro switches. The reinforcement mechanism is installed in the housing and comprises at least a reinforcing part which is fixed in the housing of a selected micro switch. The micro switches and the base are installed on both sides of the cross beam and the micro switches are installed on top of the corresponding regulating levers. The invention has completely eliminated the oil leakage problem and needs not fill silicon oil and has the advantage of shock resistance. The invention can be well applied to the SF6 electric devices.
