High-precision temperature control test testing device

Abstract

The utility model discloses a high-precision temperature control test testing device, which relates to the technical field of temperature control tests and comprises a heat preservation box, a fixed base is mounted in the heat preservation box, a groove is formed in the upper surface of the fixed base, and a movable rod penetrates through the interior of a limiting groove; a connecting block is installed at the right end of the movable rod, and a threaded rod is installed at the inner bottom of the heat preservation box. The high-precision temperature control test device is provided with the semi-bevel gear, when the semi-bevel gear is meshed with the first bevel gear, the rotating shaft is driven to rotate clockwise, the rotating shaft drives the thermal radiation lamp to rotate clockwise, and after the gear end of the semi-bevel gear is separated from the first bevel gear, the semi-bevel gear can be meshed with the second bevel gear. And the rotating shaft drives the heat radiation lamp to rotate anticlockwise, so that the heat radiation lamp rotates leftwards and rightwards, local heating of objects on the placement table is avoided, the placement table does not need to be rotated, and therefore the objects on the placement table are prevented from falling off.
