[0017] 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 in 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.

[0018] See also Figure 1-3 The utility model provides a technical solution: a gas flow measurement device that is easy to fix, comprising:

[0019] A measuring instrument body 1, a connecting seat 2 is fixedly installed on the measuring instrument body 1, a display screen 3 is fixedly installed on the connecting seat 2, flanges 4 are fixedly welded at both ends of the measuring instrument body 1, locking mechanisms 5 are provided on the front and rear sides of the measuring instrument body 1, the locking mechanism 5 includes two supporting seats 6, the two supporting seats 6 are fixedly welded on the outer wall of the measuring instrument body 1, a through groove 7 is opened on the supporting seat 6, a moving seat 8 is slidably connected in the through groove 7, a pair of connecting columns 9 are fixedly welded on the outer wall of the moving seat 8, an arc-shaped locking block 10 is fixedly welded on the pair of connecting columns 9, a locking groove 11 is opened on the arc-shaped locking block 10, and an adjustment component is provided on the two supporting seats 6.

[0020] The adjustment assembly includes a bidirectional screw 12, which is rotatably mounted on two support seats 6. Two symmetrically arranged moving blocks 13 are threadedly connected to the bidirectional screw 12. Push-pull rods 14 are rotatably mounted on the two moving blocks 13. The ends of the two push-pull rods 14 away from the moving blocks 13 are respectively rotatably mounted on two moving seats 8. A handwheel 15 is fixedly mounted on one end of the bidirectional screw 12. The handwheel 15 is convenient for screwing and rotating the bidirectional screw 12. When the bidirectional screw 12 rotates, the two moving blocks 13 can move toward or away from each other on the bidirectional screw 12, thereby driving the two push-pull rods 14 to flip, so that the two moving seats 8 slide in the through groove 7 to adjust the arc locking block 10.

[0021] Slide grooves 16 are provided on the top and bottom side walls of the through groove 7, and sliders 17 are fixedly welded on the top and bottom ends of the movable seat 8. The slider 17 is slidably connected in the slide groove 16. The sliding cooperation between the slider 17 and the slide groove 16 can play a guiding and limiting role for the movable seat 8.

[0022] Sealing pads 18 are fixedly installed at both ends of the measuring instrument body 1. The sealing pads 18 can improve the sealing performance of the measuring instrument during installation and prevent gas leakage.

[0023] The edge of the locking groove 11 is arranged to be inclined, so that when the arc-shaped locking block 10 is inserted, the connecting flange can easily slide into the locking groove 11 .

[0024] Working principle: During the use of the utility model, when installing the measuring instrument, the measuring instrument body 1 can be placed between two gas pipes, so that the two flanges 4 are respectively fitted with the connecting flanges of the two gas pipes, and then the hand wheel 15 is turned forward in sequence to drive the bidirectional screw 12 to rotate forward. When the bidirectional screw 12 rotates forward, the two moving blocks 13 can move backwards on the bidirectional screw 12, thereby driving the two push-pull rods 14 to flip, and push the two moving seats 8 to slide in the through groove 7 toward the measuring instrument body 1. The moving seat 8 drives the arc-shaped locking block 10 to be pressed onto the flange 4 and the connecting flange, and the flange 4 and the connecting flange are locked in the locking groove 11, completing the fixed installation of the gas measuring instrument. The operation is simple and convenient, saving time and effort, and greatly improving the maintenance efficiency of the gas flow meter.
