In the present embodiment, the structure in which the smoothing blade 111 is slidably connected to the carrier frame 30 is limited, and the cooperation between the smoothing blade 111 and the detection cover 50 is limited. When the detection cover 50 moves downwards for detection, the translation screw rod 37 rotates to drive the sliding block to slide in the translation slideway 35, so that the smoothing scraper 111 is pushed from one side to the other side in the process of moving the detection cover 50 downwards, and fine powder at the bottom in the detection frame is scraped and stays at the other side; in the process of moving up after the detection of the detection cover 50, the translation screw rod 37 is reversed, and then in the process of moving down the detection cover 50, the smoothing scraper 111 is translated to the original side, and then fine powder at the bottom of the detection frame is smoothed before the detection, so that the next detection is facilitated.

Specifically, the conversion set of triangles is including rotating forward set of triangles and reverse set of triangles of connecting in detection cover 50 bottom, one is vertical form another for folding form under forward set of triangles and the reverse set of triangles original state, the pivot of forward set of triangles and reverse set of triangles is all worn out detection cover 50 and one end fixedly connected with switching gear, detection cover 50 outside sliding connection has the conversion rack, the conversion rack is located switching gear top and meshes with it. Specifically, a conversion push rod is fixedly installed on the side wall of the detection cover 50, a top support rod is fixedly connected to the top of the conversion rack, and the output end of the conversion push rod is fixedly connected with the top support rod.

Referring to fig. 1 to 4, in one embodiment of the present utility model, the detecting tank 11 and/or the detecting cover 50 are/is connected to a barometer at a side thereof.

In this embodiment, the air pressure value in the region of the detection groove 11 or the detection hood 50 is monitored by an air pressure gauge. First, when we detect the air tightness of the door and window, if the air tightness of the door and window is insufficient, the air in the detecting cover 50 permeates into the detecting groove 11, which then causes the air pressure of the detecting groove 11 to increase, and by communicating with the air pressure gauge at the side of the detecting groove 11, we can determine whether the air tightness of the door and window is insufficient by observing whether the value of the air pressure gauge increases. Secondly, since the gas in the detecting cover 50 permeates into the detecting groove 11, by comparing the air pressure value observed at the side of the detecting cover 50 with the preset air pressure value, if the air pressure value is significantly reduced, it can be determined that the door and window has insufficient air tightness. In addition, during the process of inflating the detection cover 50 through the inflation device, the air pressure gauge communicated with the side edge of the detection cover 50 can be observed, and the air pressure in the detection cover 50 is controlled to reach a preset value. Again, the barometer can be used for slight gas leakage detection, is favorable to promoting detection accuracy.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
