The invention discloses a dry gas seal structure suitable for vibration detection. The dry gas seal structure comprises a shaft sleeve, a movable ring, a fixed ring, a push ring and a spring base. Circular grooves are formed in the fixed ring and the push ring correspondingly and used for stably containing vibration acceleration sensors. Symmetrical through holes are formed in the push ring and the spring base so that sensor signal lines can be guided. By means of the structure, the problem of dry gas seal workpiece vibration detection under the working condition is effectively solved on the basis of not influencing the normal operation of a dry gas seal. The dry gas seal structure has the beneficial effects that the structure is simple, machining is facilitated, and measurement of the vibration situation of axial moving workpieces is achieved under the condition that the normal working condition operation of the axial moving workpieces in the dry gas seal is not influenced.
