Description

Technical Field

[0001] This utility model relates to the field of magnetoelectric encoder technology, specifically an explosion-proof magnetoelectric encoder. Background Technology

[0002] A magnetoelectric encoder is a measuring device that uses sensors such as magnetoresistive or Hall elements to measure the angle or displacement of a magnetic material. Changes in the angle or displacement of the magnetic material cause changes in resistance or voltage. By detecting and processing these changes, a pulse signal or analog signal is output, thus achieving the measurement purpose. Magnetoelectric encoders are characterized by vibration resistance, corrosion resistance, pollution resistance, interference resistance, and a wide temperature range. Therefore, they can be widely used in industrial control, machinery manufacturing, shipbuilding, textiles, printing, aviation, aerospace, radar, communications, and military industries.

[0003] Most current magneto-electric encoders use a single-layer metal shell. When the internal encoder components malfunction and generate high temperatures that cause the shell to crack, the lack of a protective structure makes it easy for fragments to fly and cause impact damage to electrical appliances installed nearby. To address this issue, we propose an explosion-proof magneto-electric encoder. Utility Model Content

Through slots are provided on the side wall of the protective cylinder and the corresponding limit seats. The output shaft of the magnetic encoder body is disposed in the through slot.

Multiple first buffer springs 7 are installed on the inner wall of one end of the protective cylinder 3 and the inner wall of the cover plate 4. The multiple first buffer springs 7 are distributed equidistantly in a ring outside the limiting seats 5. Annular buffer plates 8 are fixedly installed on the multiple first buffer springs 7. The annular buffer plates 8 are slidably connected to the limiting seats 5. Multiple arc-shaped buffer plates 9 are arranged equidistantly in a ring inside the cavity of the protective cylinder 3. Multiple second buffer springs 10 are fixedly installed on the arc-shaped buffer plates 9. The end of the second buffer spring 10 away from the arc-shaped buffer plate 9 is fixedly connected to the inner wall of the protective cylinder 3.

[0022] Two symmetrically arranged limiting rods 11 are fixedly welded to the inner wall of the protective cylinder 3. The limiting rods 11 are provided with sliding grooves 12. Two fixing rods 13 are fixedly welded to the outer wall of the magneto-electric encoder body 1. The fixing rods 13 are slidably connected in the sliding grooves 12. By the insertion and cooperation of the fixing rods 13 and the limiting rods 11, the magneto-electric encoder body 1 can be easily limited in the protective cylinder 3 to prevent it from deflecting.

[0023] A threaded cylinder 14 is fixedly welded to the inner wall of the cover plate 4. A threaded groove adapted to the threaded cylinder 14 is opened on the inner wall of the opening of the protective cylinder 3.
