[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-3, an environmental protection waste gas sampling and collecting box, comprising a box body 1, an air suction pump 4 is installed at the inner bottom end of the box body 1, and the top of the air suction pump 4 is connected to an air pipe 3, an air suction head 6 is installed at the other end of the air pipe 3, and the top of the air suction head 6 is threadedly connected to a filter cover 7, a movable plate 2 is sleeved on the middle part of the outer wall of the air pipe 3, and a baffle 9 is movably connected to the inner side of the movable plate 2, the movable plate 2 forms a sliding structure with the box body 1 through the baffle 9, and the movable plate 2 is distributed in two groups, after the movable plate 2 is pushed upward by the collected waste gas, the movable plate 2 can be moved up along the second reserved groove 14 through the baffle 9, a slider 10 is fixed to the outer wall of the baffle 9, and a spring 11 is connected to one side of the slider 10, the baffle 9 forms a sliding structure with the movable plate 2 through the slider 10 and the first reserved groove 12, and the slider 10 forms an elastic structure with the movable plate 2 through the spring 11, after the baffle 9 moves along the second reserved groove 14, the baffle 9 can The movable plate 2 is deep enough to penetrate into the movable plate 2, so that the slider 10 connected to its outer wall slides along the inner side of the first reserved groove 12, and when no external force is applied to the outer side of the baffle plate 9, the spring 11 can push the slider 10 to reset under the action of the reset force. A through hole 13 is provided in the middle of the movable plate 2, and a first reserved groove 12 is provided on the inner side of the movable plate 2. The inner wall of the first reserved groove 12 is connected to the other end of the spring 11. A partition plate 8 is vertically installed in the middle of the inner side of the box body 1, and second reserved grooves 14 are provided on both sides of the outer wall of the partition plate 8 and both sides of the inner wall of the box body 1. The inner side of the second reserved groove 14 is inclined, and the second reserved groove 14 and the baffle plate 9 are slidably connected. By setting the inner side of the second reserved groove 14 to an inclined shape, the baffle plate 9 that moves up synchronously with the movable plate 2 can be effectively pushed, so that the baffle plate 9 penetrates into the movable plate 2 and completes the clamping operation of the air pipe 3.

[0022] A guide rod 5 is connected to the top of the movable plate 2, and a reserved hole 15 is opened on the front of the guide rod 5. The guide rod 5 and the top of the box body 1 are through-set, and the guide rod 5 moves up along the inner side of the top of the box body 1, which can effectively limit the horizontal direction of the movable plate 2 and is not prone to tilting.
