[0036] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The upper auxiliary part 63 includes a first connecting plate 631, a pressing groove 632 and a second screw hole 633.

[0037] During specific operation, when installing the air flow meter, first slide and install the first connecting plate 631 on the vertical rod 413 respectively, then pass the vertical rods 413 on both sides through the first sliding hole 412 and then through the main tube 1, and the hexagonal protrusion 621 will press on the upper end surface of the fixed horizontal plate 411 so that the first sliding hole 412 will not continue to drop. At this time, the positioning block on the vertical rod 413 is not inserted into the positioning groove, so that the opening of one of the slots 414 faces the rear circulation tube 3. At this time, the flat plate of the first connecting plate 631 close to the fixed horizontal plate 411 will be moved into the pressing groove 632, and the hexagonal protrusion 621 will press this end of the first connecting plate 631 on the upper end surface of the fixed horizontal plate 411 to limit the movement of the first connecting plate 631.

[0038] See also Figure 2 , Figure 5 , Figure 6 and Figure 7 The support portion 42 includes a swivel 421, a filter 422 and a second sliding hole 423. The main body tube 1 is provided with a swivel 421 which is symmetrical in front and back through a bearing. The filter 422 is fixedly installed on the inner ring wall of the swivel 421. The filter 422 is penetrated by a second sliding hole 423 which is symmetrical in top and bottom, and the position of the second sliding hole 423 corresponds to the slot 414.

[0039] See also Figure 2 and Figure 5 The splicing portion 43 includes a splicing protrusion 431 and an alignment hole 432. A plurality of mutually staggered splicing protrusions 431 are evenly arranged along the circumference of the swivel 421 on the opposite surface of the circulation tube 3. The opposite surface of the swivel 421 and the circulation tube 3 is wrapped with a rubber layer. A plurality of alignment holes 432 are evenly opened along the circumference on a side wall of the swivel 421 close to the corresponding circulation tube 3.

[0040] See also Figure 2 , Figure 3 and Figure 8 The positioning portion 51 includes an insertion rod 511 and a limiting column 512. An insertion rod 511 corresponding to the alignment hole 432 is fixedly installed on the side wall of the circulation tube 3 close to the main tube 1, and a limiting column 512 corresponding to the alignment hole 432 is fixedly installed on the inner ring wall of the main tube 1. The limiting column 512 and the corresponding insertion rod 511 are provided with corresponding embedding grooves.

[0041] See also Figure 2 , Figure 5 , Figure 6 and Figure 7The matching part 52 includes an L-shaped support plate 521 and a hook plate 522. The inner ring wall of the circulation tube 3 is fixedly installed with an L-shaped support plate 521 that is symmetrical up and down on one side close to the main tube 1. The horizontal section of the L-shaped support plate 521 is fixedly installed with a triangular plate at one end close to the flow electronic sensor 2. The triangular plate is inserted into the corresponding second sliding hole 423. The end of the triangular plate close to the flow electronic sensor 2 is fixedly installed with a hook plate 522. The opening directions of the hook plates 522 that are symmetrical up and down on the same side are opposite. The hook plates 522 are embedded in the corresponding card grooves 414. The end of the hook plate 522 close to the flow electronic sensor 2 is flexible.

[0042] During the specific operation, after the vertical rod 413 is installed, the swivel 421 is rotated to rotate it with the second sliding hole 423 from a horizontal state to a vertical state, and then the circulation tube 3 is moved closer to the main tube 1, so that the triangular plate of the horizontal section on the L-shaped support plate 521 is inserted into the second sliding hole 423. At this time, the staggered splicing protrusions 431 on the opposite surfaces of the swivel 421 and the circulation tube 3 will approach each other until the opposite surfaces of the swivel 421 and the circulation tube 3 are fitted so that the splicing protrusions 431 are mutually engaged, so that the circulation tube 3 and the swivel 421 are combined into a whole.

[0043] In the process of the circulation tube 3 approaching the rotating ring 421, the insertion rod 511 will pass through the corresponding alignment hole 432 to reach the main body tube 1, and then the circulation tube 3 will be rotated to make it rotate synchronously with the rotating ring 421 until the second sliding hole 423 is rotated from the vertical state to the horizontal state again. In this process, the triangle plate of the horizontal section on the L-shaped support plate 521 will rotate with the center of the rotating ring 421. When the triangle plate brings the hook plate 522 to the corresponding slot 414, the hook plate 522 contacts the vertical rod 413, which makes the hook plate 52 2, the flexible material at the front end is deformed, so that the vertical rod 413 is placed in the openings of the corresponding upper and lower hook plates 522 at the same time, and then the hexagonal protrusion 621 is rotated to rotate with the vertical rod 413, so that the positioning block is stuck in the positioning groove. During this process, the slot 414 will rotate to the rear end position of the hook plate 522, so that the hook plate 522 is stuck in the slot 414, thereby fixing the flow tube 3 and the rotating ring 421, making the splicing protrusion 431 between the two more tightly connected, and fixing the flow tube 3 on the main tube 1.

[0044] At the same time, when the triangle plate rotates about the center of the rotating ring 421, the insertion rod 511 contacts the corresponding limiting column 512, and the insertion rod 511 is embedded in the embedding groove of the limiting column 512. The mutual embedding between the insertion rod 511 and the limiting column 512 will further assist in the fixation of the circulation tube 3, increase the stability of the connection between the two, and avoid displacement caused by vibration or pressure changes.

[0045] When the air flow meter needs to be disassembled, it is only necessary to rotate the vertical rod 413 in the opposite direction to disengage the slot 414 from the hook plate 522, and then rotate the circulation tube 3 in the opposite direction to pull the main tube 1 out of the circulation tube 3, so that the circulation tube 3 can be quickly aligned and fixed during the process of engaging the hook plate 522 and the slot 414 with each other. When maintenance is required, it is only necessary to rotate the vertical rod 413 and the circulation tube 3 in the opposite direction to complete the disassembly of the air flow meter, so that there is no need to operate each bolt separately, and installation and disassembly can be completed through simple engagement and rotation actions, which greatly shortens the operation time and improves the efficiency of maintenance work.

[0046] See also Figure 1 , Figure 2 and Figure 4 The fixing part 61 includes a fixing plate 611, an electric control component 612 and a first screw hole 613. The fixing plate 611 is arranged above the fixing transverse plate 411. The electric control component 612 cooperating with the flow electronic sensor 2 is fixedly installed on the fixing plate 611. The upper end surface of the fixing transverse plate 411 is provided with a first screw hole 613 symmetrical in front and back. The fixing plate 611 is fixed to the upper end surface of the fixing transverse plate 411 by a first bolt cooperating with the first screw hole 613.

[0047] During the specific work, after fixing the circulation tube 3 to the main tube 1, the worker holds the electric rotating tool to rotate the first bolt, thereby fixing the fixing plate 611 to the fixed horizontal plate 411. At this time, the fixing plate 611 will limit the hexagonal protrusion 621 through the hexagonal alignment groove 622, so as to fix the position of the vertical rod 413, and at the same time squeeze the first connecting plate 631 into the pressing groove 632, so as to complete the fixation of the first connecting plate 631. At the same time, during the rotation of the circulation tube 3, the second screw hole 633 will be rotated to the bottom of the first connecting plate 631, and then the first connecting plate 631 can be fixedly connected to the circulation tube 3 by the second bolt, so that after the circulation tube 3 is fixed to the main tube 1, the circulation tubes 3 on both sides are auxiliary fixed by the first connecting plate 631.

[0048] See also Figure 1 and Figure 2 The lower auxiliary part 64 includes a second connecting plate 641 and a slot 642. The second connecting plate 641 is arranged below the main tube 1. A third screw hole is opened on the outer ring wall of the circulation tube 3. A third bolt is arranged in the third screw hole. The third bolt passes through the second connecting plate 641 and is inserted into the third screw hole. A slot 642 corresponding to the vertical rod 413 is opened on one side wall of the second connecting plate 641 close to the main tube 1.

[0049] During the specific operation, after the first connecting plate 631 is fixed, the slot 642 on the second connecting plate 641 is aligned with the bottom of the vertical rod 413 and inserted, and the two sides of the second connecting plate 641 are respectively fixed to the flow tube 3 on the front and rear sides by the third bolt, so that the flow tube 3 on both sides is formed into a whole with the main tube 1, which provides multi-point support for the installation of the air flow meter, makes the connection between the flow tube 3 and the main tube 1 more stable, reduces the possibility of displacement and vibration, and through modular design, the flow tube 3 and the main tube 1 can be more conveniently separated and combined during inspection and maintenance, further simplifying the operation steps.
