[0032] As Figures 1-4 shown, the present utility model provides a technical solution: a sealing performance detection device for the production of sealing strips, including a detection table 1. Support seats 101 are symmetrically installed near the left and right sides of the top of the detection table 1. A threaded rod 102 is arranged inside the support seat 101. One end of the threaded rod 102 extending to the inner side of the support seat 101 is rotatably connected to a pressing plate 103. Inside the support seat 101 and located at the top and bottom of the threaded rod 102, a limiting rod 104 is slidably connected. The limiting rod 104 is fixedly connected to the pressing plate 103, which can limit the moving pressing plate 103 to prevent it from rotating together with the threaded rod 102. A detection box 2 is arranged on the top of the detection table 1 and between the two support seats 101. Card slots 201 are formed near the periphery of the front and back of the detection box 2. A sealing strip main body 202 is arranged inside the card slots 201.

[0033] Embodiment 2

[0034] As Figures 1-4As shown in the figure, an air inlet pipe 203 is installed near the center at the top of the detection box 2. The air inlet pipe 203 is communicated with the detection box 2. Through the air inlet pipe 203, gas can be input into the detection box 2 for airtightness detection. Plug-in blocks 204 are symmetrically welded on the front and back of the detection box 2. Plug-in slots 2041 are formed through the left and right sides inside the plug-in blocks 204. Plug rods 1031 are symmetrically arranged on the front and back of the pressing plate 103. The plug rods 1031 are adapted to the plug-in slots 2041. Through the adaptation of the plug rods 1031 and the plug-in slots 2041, the plug rods 1031 can be inserted into the plug-in slots 2041, so as to limit the position between the pressing plate 103 and the detection box 2 and prevent it from shifting during the detection process. A pressure gauge 205 is installed near the bottom on the right side of the detection box 2. The pressure gauge 205 is communicated with the detection box 2. Through the pressure gauge 205, the air pressure condition inside the detection box 2 can be observed at any time, so as to improve the detection accuracy. Fixed rows 206 are symmetrically installed near both sides of the periphery of the detection box 2. Soft hairs 2061 are evenly adhered to the outside of the fixed rows 206. By observing whether the soft hairs 2061 float, it can be judged whether there is air leakage in the gap between the detection box 2 and the pressing plate 103, so as to achieve the purpose of detecting airtightness. Adjustable floor feet 105 are installed at the bottom of the detection table 1 near the four corners through bolts. By rotating the adjustable floor feet 105, the height of the detection table 1 can be adjusted. A fixed base 207 is arranged at the bottom of the detection box 2. The fixed base 207 is fixed to the detection table 1 and the detection box 2 through bolts respectively. Through the fixed base 207, the detection box 2 can be made more firm and the use stability can be improved.

[0035] The working process of the present utility model: When using a sealing strip airtightness detection device for the production of sealing strips to detect the airtightness of the sealing strip, first place the sealing strip body 202 into the clamping groove 201, rotate the threaded rod 102 to drive the pressing plate 103 to approach both sides of the detection box 2 and press the sealing strip body 202. Pass gas into the detection box 2 through the air inlet pipe 203 by an external air pump, and observe the pressure gauge 205. After reaching the required air pressure, stop supplying gas. After waiting for a period of time, if the air pressure does not drop, it indicates that the airtightness of the sealing strip body 202 is good. If the air pressure drops, observe whether the soft hairs 2061 float. Find the corresponding floating soft hairs 2061 to determine that the airtightness of the sealing strip body 202 on the corresponding side is not good. It can detect two sealing strip bodies 202 at the same time, greatly improving the detection efficiency and effectively improving the practicability.
