Abstract
The utility model relates to a minitype aseismatic quartz flexible accelerometer, which comprises a pin, a shell, a servo circuit, a lower torquer, a pendulous reed, and an upper torquer. The minitype aseismatic quartz flexible accelerometer is characterized in that double-side typesetting is implemented on the servo circuit; the outer edge of the pendulous reed is inwards provided with a groove; a central hole is arranged on the pendulous reed; a through hole is also arranged on the pendulous reed; a boss is arranged in the center of the lower end surface of the lower torquer; a screw hole is arranged on the lower end surface of the lower torquer; a penetrating hole is arranged between the upper end surface and the lower end surface of the upper torquer; the central hole is matched with the boss; the penetrating hole and the through hole correspond to the screw hole; a bolt penetrates through the penetrating hole and the through hole to be matched with the screw hole to connect the upper torquer, a pendulous reed group, and the lower torquer into a whole body. The minitype aseismatic quartz flexible accelerometer has simple structure; as the double-side typesetting is implemented on the servo circuit, and the pendulous reed is effectively limited on directions of a pendulous reference axis and an output reference axis, the minitype aseismatic quartz flexible accelerometer not only has small size, but also has strong aseismatic capacity.
Description
Technical field
The utility model relates to flexure accelerometers, particularly small-sized antidetonation quartz flexible accelerometer.
Background technology
Fields such as Aeronautics and Astronautics, automobile, petroleum drilling extensively adopt accelerometer to detect carrier linear acceleration information, and are more and more higher to the requirement of accelerometer along with development of science and technology, wish that urgently the accelerometer volume is little and range is big.Existing accelerometer not only volume is big, and shock resistance is poor, and the acceleration that surpasses 100g impacts and tends to influence the accelerometer operate as normal.Therefore, design a kind of simple in structure, volume is little and small-sized antidetonation quartz flexible accelerometer that shock resistance is strong is very necessary.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, volume is little and small-sized antidetonation quartz flexible accelerometer that shock resistance is strong.
For achieving the above object, the utility model adopts following technical scheme: a kind of small-sized antidetonation quartz flexible accelerometer, comprise pin, shell, servo circuit, following torquer, pendulum and last torquer, it is characterized in that servo circuit adopts two-sided composing, the outer of pendulum inwardly offers groove, pendulum is provided with center pit, also be provided with through hole on the pendulum, the center, lower surface of following torquer is provided with boss, the lower surface of following torquer is provided with screw, be provided with through hole between the upper and lower end face of last torquer, described center pit matches with boss, described through hole, through hole is corresponding with screw, and bolt passes through hole, cooperate with screw behind the through hole and will go up torquer, pendulum group and following torquer are connected as a single entity.
Further, described through hole is two, and described screw is two, and described through hole is two.
Further, described center pit is a circular hole, and described boss is a right cylinder.
The utility model is simple in structure, because servo circuit adopts two-sided composing and effectively spacing on pendulum reference axis and output reference direction of principal axis to pendulum, therefore, not only volume is little, and shock resistance is strong.
