An apparatus for detecting the airtightness of a telescope

Abstract

This utility model relates to the field of telescope testing and discloses a device for testing the airtightness of a telescope. The device includes a housing, a door hinged to the right end of the front surface of the housing, a pressure gauge on the upper surface of the housing, an air inlet device on the left surface of the housing, an air suction connection device on the left surface of the housing, a latch at the front end of the left surface of the housing, a sealing assembly on the rear surface of the door, and a fixing mechanism inside the housing. The fixing mechanism includes a clamping assembly, which includes a bidirectional threaded rod. In this utility model, a compression spring causes a moving plate to move downwards and clamp the upper and lower ends of the telescope. The bidirectional threaded rod drives a guide plate to clamp clamping plates one and two from the left, right, front, and rear sides, achieving multi-directional stable fixation of the telescope, preventing it from falling off during rotation during testing, enhancing the stability of the telescope, and ensuring the quality of the test.
