Smoke-proof performance testing device for fireproof doors and windows

Abstract

The utility model relates to the related technical field of fireproof door and window testing, in particular to a fireproof door and window smoke-proof performance testing device which comprises a testing bin and an installation mechanism, one side of the surface of the testing bin is provided with the installation mechanism, and the other side of the surface of the testing bin is provided with a testing mechanism. According to the device for testing the smoke-proof performance of the fireproof door and window, through the arrangement of the mounting mechanism, firstly, a testing door is attached to one end of a testing bin, then a driving motor is started, the driving motor drives a gear to rotate in a mounting groove, and a supporting rod penetrates through a mounting base through a limiting hole; meshing teeth on one sides of the surfaces of the supporting rods are in meshed connection with the gears, so that when the gears are driven by the driving motor to rotate in the mounting grooves, the gears drive the supporting rods to move towards the direction of the testing bin through meshing movement with the meshing teeth, and at the moment, fixing rods fixedly connected with one ends of the two supporting rods move towards the direction of the testing door; therefore, the test door is fixedly installed at one end of the test bin through the fixing rod.
