[0018] Please see Figure 1-Figure 1 The present application provides a device for measuring the outer dimensions of an inflatable headband, characterized in that the oxygen mask to be measured is fixed on the mounting base, and the outer dimensions of the inflatable headband after expansion can be measured by moving the extension bracket and the baffle, and by measuring the scale on the side of the slide and the extension bracket.
[0019] Specifically, it includes: mounting base 1, first base 2, left and right baffles 3, stabilizing block 4, extension bracket 5, and upper baffle 6.
[0020] Fix the oxygen mask to be tested onto the mounting base 1, press the inflation button on the headband to inflate the headband to its maximum size, and simultaneously adjust the extension bracket 5, baffle 3 and upper baffle 6 so that the headband just contacts the four baffles. Observe the scale on the side of the first base 2 and the extension bracket 5 to obtain the outer dimensions of the headband.
[0021] This application is able to measure the outer dimensions of the inflatable headband on the oxygen mask of the unit after inflation, maintain its outer dimension shape, and easily determine whether the inflatable headband size is qualified.
[0022] In this embodiment of the application, an inflatable headband outer dimension measuring device is provided, which specifically includes: a mounting base 1, a slide 2, left and right baffles 3, a stabilizing block 4, an extension bracket 5, and an upper baffle 6.
[0023] The mounting base is used to install the unit's oxygen mask, fixing its position relative to the mounting base. One side of the mounting base has an opening to facilitate the insertion of the unit's oxygen mask into the bottom and to provide space for the air supply line. Below the mounting base is a rectangular support column that can be gripped and moved. The bottom has a T-shaped structure that mates with the first T-shaped sliding groove on the first base.
[0024] The first base is rectangular in shape, with a T-shaped groove on its upper surface for embedding the mounting base and extension bracket. Mounting holes are located at both ends of the first base for mounting stabilizing blocks. The bottom surface of the first base rests on a stable plane. The first base has graduations for reading the measurements.
[0025] The stabilizing block is a cuboid with at least two through holes on its side. It is connected to the first base by bolts to enhance the stability of the entire device. If necessary, a through hole can be opened on the top of the stabilizing block to fix it to the mounting plane of the entire device.
[0026] The extension bracket has a T-shaped symmetrical structure, including a second base and a support column. The second base has a T-shaped second groove for mounting the left and right supports, and is also marked with graduations for reading.
