Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of test for ventilation equipment defects inspecting
Device, including detection fixing seat 1, described 1 inner cavity lower surface of detection fixing seat or so end are provided with pawl slot 2, and the detection is solid
1 inner sidewall lower end of reservation has been connected through a screw thread ventilation equipment 3, and third is equipped between the detection fixing seat 1 and ventilation equipment 3
Gasket 14.14 upper end of third gasket is equipped with pawl, and the pawl is movably connected in 2 slot of pawl slot.The detection
Fixing seat 1 is fixed on ventilation equipment 3, convenient for being replaced and being moved to test device.The fixed peace of the third gasket 14
Exit loaded on ventilation equipment 3 passes through screw thread when moving down on ventilation equipment 3 in detection fixing seat 1, third gasket
Pawl on 14 is tightly stuck in 2 slot of pawl slot, during screw thread rotation, firm to third gasket 14 can be fastened.
