[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Please see Figures 1-5This embodiment provides an integrated bent-tube flow meter, including a flow meter body 1 and a protective cavity 2. The flow meter body 1 consists of a bent tube 11 and an instrument panel 12. A bottom cavity 13 is symmetrically installed on the outer wall of the bent tube 11. A first spring rod 25 is installed at the bottom of the bottom cavity 13. A disc 24 is installed on the upper end face of the first spring rod 25. A through groove is symmetrically opened on the outer wall of the disc 24. A second spring rod 14 is arranged in the through groove and inserted into the inner wall of the bottom cavity 13. The protective cavity 2 is installed on the upper end face of the disc 24, and the instrument panel 12 is arranged in the protective cavity 2. 2. A straight hole is provided on the upper end face of the outer wall of the through groove. A handle 15 is installed on the outer wall of the second spring rod 14. The handle 15 passes through the straight hole and is connected to it by a sliding fit. During operation, the protective cavity 2 can protect the surface of the instrument panel 12 to prevent it from being damaged by bumps. The second spring rod 14 can position and fix the disc 24 to ensure the stability of the protective cavity 2. Moving the handle 15 on the inner end will cause the second spring rod 14 to retract, and then the first spring rod 25 will drive the protective cavity 2 to move upward and open, making it easier to view the instrument panel 12 during operation.

[0020] An inner position plate 16 is arranged in front of the instrument panel 12. A soft pad 17 is installed on the rear end face of the inner position plate 16, and a third spring rod 18 is installed on the front end face of the inner position plate 16. A handle 19 is installed on the front end face of the third spring rod 18. The rear end face of the handle 19 is connected to the front end face of the protective cavity 2 by a rotating fit. During operation, the soft pad 17 provides shock absorption and protection for the surface of the instrument panel 12, avoiding the risk of breakage. The handle 19 can drive the inner position plate 16 to rotate. Since the soft pad 17 is installed on the rear end face of the inner position plate 16, the handle 10 can drive the soft pad 17 to rotate, thereby enabling thorough wiping and cleaning of the surface of the instrument panel 12. The third spring rod 18 presses the soft pad 17, making it fit tightly against the side wall of the instrument panel 12, further ensuring the cleaning effect.

[0021] A light 21 is installed at the bottom of the protective cavity 2, and the light 21 is arranged in front of the instrument panel 12. When the protective cavity 2 moves upward during operation, the light 21 is turned on, so that the values ​​on the surface of the instrument panel 12 can be clearly seen in dim environments, further improving the versatility of the device.

[0022] The outer wall of the bend 11 is rotatably mounted with a U-shaped frame 22 via a pin. The U-shaped frame 22 is connected to the upper end face of the protective cavity 2 by a first bolt 23. During operation, the U-shaped frame 22 limits and fixes the protective cavity 2 to prevent it from opening accidentally, thereby further improving the overall stability of the device.

[0023] In actual operation, the protective cavity 2 can protect the surface of the instrument panel 12 to prevent it from being damaged by bumps. The second spring rod 14 positions and fixes the disc 24 to ensure the stability of the protective cavity 2. The inner end moving handle 15 drives the second spring rod 14 to retract, and then the first spring rod 25 drives the protective cavity 2 to move upward and open, making it easier to view the instrument panel 12 during operation.
