They are widely used in industrial process control, municipal water supply, wastewater treatment, and many other fields.

[0003] Traditional insertion flow meter mounting bases typically use threaded connections to fix the flow meter probe to the installation pipe. In humid or corrosive environments, the threaded connections are prone to rusting and seizing. This makes it difficult to separate the flow meter probe from the installation pipe, and in severe cases, even requires destructive disassembly methods, causing great inconvenience to equipment maintenance and management. To address these problems, the inventors have proposed an insertion flow meter mounting base to solve the aforementioned issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5 As shown, this utility model provides an insertion type flow meter mounting base, including a pipe 1 and a flow meter body 2. A connecting pipe 3 is fixedly connected to the pipe 1, and a connecting seat 4 is fixedly connected to the bottom end of the flow meter body 2. The connecting pipe 3 and the connecting seat 4 are connected by two fixing mechanisms 5, and the two fixing mechanisms 5 are symmetrically distributed.

[0021] The fixing mechanism 5 includes a pressure rod 51, which is rotatably connected to one side of the connecting pipe 3. A rotating frame 52 is rotatably connected to the side of the pressure rod 51. A U-shaped plate 53 is slidably engaged inside the rotating frame 52. A threaded rod 54 is rotatably connected to the top of the U-shaped plate 53. The top of the threaded rod 54 moves through the rotating frame 52 and is rotatably connected to a retaining ring 55. Two symmetrically distributed hooks 56 are fixedly connected to the side of the connecting seat 4. The retaining ring 55 is sleeved on the hooks 56. A spring 57 is provided between the top of the inner wall of the rotating frame 52 and the U-shaped plate 53. The spring 57 is movably sleeved on the outside of the threaded rod 54.

[0022] The outer side of the threaded rod 54 is threadedly connected to a movable plate 58, which is slidably engaged in the U-shaped plate 53. The bottom end of the spring 57 is fixedly connected to the top surface of the movable plate 58.

[0023] By adopting the above technical solution, by rotating the threaded rod 54, the U-shaped plate 53 limits the movement plate 58, and at the same time drives the movement plate 58 to move vertically along the outside of the threaded rod 54, so that the movement plate 58 applies a preload force to the spring 57, thereby ensuring that the locking mechanism operates in the best condition.

[0024] Guide posts 6 are fixedly connected to both sides of the U-shaped plate 53, and guide grooves 7 are opened on both sides of the rotating frame 52. The guide posts 6 are slidably engaged in the guide grooves 7.

[0025] By adopting the above technical solution, the cooperation between the guide post 6 and the guide groove 7 facilitates the vertical movement of the U-shaped plate 53 and improves the stability of the U-shaped plate 53 during movement.

[0026] The bottom end of the threaded rod 54 extends to the bottom end of the U-shaped plate 53 and is fixedly connected to the knob 59.

[0027] By adopting the above technical solution and setting the knob 59, it is easier to rotate and adjust the threaded rod 54.

[0028] The bottom end of the connector 4 is provided with an insertion groove 12. The top end of the connector 3 is movably inserted into the interior of the insertion groove 12. A fixing ring 8 is fixedly connected to the top end of the inner wall of the insertion groove 12. A sealing ring 9 is provided between the outer side of the fixing ring 8 and the inner wall of the insertion groove 12. The top end of the connector 3 is in close contact with the sealing ring 9.

[0029] By adopting the above technical solution and setting the sealing ring 9, the sealing performance of the contact surface between the connecting pipe 3 and the sealing ring 9 can be improved, thereby preventing fluid leakage inside the pipe 1.

[0030] Two symmetrically distributed positioning rods 11 are fixedly connected to the side of the connecting pipe 3. Two symmetrically distributed positioning grooves 10 are opened on the inner wall of the flow meter body 2. The positioning rods 11 are slidably engaged in the corresponding positioning grooves 10.

[0031] By adopting the above technical solution, the positioning groove 10 and the positioning rod 11 are matched to facilitate the positioning of the connecting seat 4 during installation.

[0032] Working principle: When installing the insertion flow meter, the positioning groove 10 and the positioning rod 11 are aligned so that the positioning rod 11 and the connecting pipe 3 are inserted into the positioning groove 10 and the insertion groove 12 respectively. Then, the retaining ring 55 is fitted on the outside of the hook 56. By rotating the pressure rod 51 downward, the hook 56 limits the retaining ring 55. At the same time, the rotating frame 52 moves downward along the outside of the threaded rod 54 and compresses the spring 57. When the pressure rod 51 rotates to the vertical position, the spring force of the spring 57 on the pressure rod 51 is in the vertical position. At this time, the spring force of the spring 57 makes the retaining ring 55 and the hook 56 tightly engaged, thereby fixing the relative position of the connecting pipe 3 and the connecting seat 4, and completing the installation of the flow meter body 2.

[0033] At the same time, by turning the knob 59, the threaded rod 54 is rotated, and the U-shaped plate 53 is used to limit the moving plate 58. At the same time, the moving plate 58 is driven to move vertically along the outside of the threaded rod 54, so that the moving plate 58 applies a preload to the spring 57 to ensure that the snap-fit ​​mechanism operates in the best condition.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
