High-resistance type quartz accelerometer

The utility model provides a high-resistance type quartz accelerometer which is improved in terms of reliability and shock resistance. The high-resistance type quartz accelerometer comprises a shell, an upper torquer, a lower torque, a pendulous reed set, an abdominal belt and a servo circuit. A pendulous reed of the pendulous reed set is a disk. The disk is provided with a non-closed ring hole which is concentric with the disk. Two ends of the ring hole are provided with an arc hole respectively, and the areas of the arc holes are larger than the area of the ring hole. According to the high-resistance type quartz accelerometer, the areas of the arc holes in the pendulous reed are increased, thereby increasing the connection area of the pendulous reed; original double supports are changed into a single support; the area of the disk is increased; an original right angle structure is changed into an arc structure; stress concentration is prevented in the movement of the pendulous reed, rigidity and reliability of the pendulous reed in the vibration are improved, and the inherent frequency of the pendulous reed is greatly increased; and the original overall area of the pendulous reed is not changed, and enough sensitivity is ensured.
