Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] As attached Figure 1-5 The sunscreen protective cover structure of a flow meter shown in the figure includes a cover shell 1, characterized in that: an observation slot 2 is opened on the surface of the cover shell 1, a cover plate 3 is hingedly provided on one side of the cover shell 1, and a rotating and telescopic component is fixedly provided on the bottom of the cover shell 1;

[0034] The rotary telescopic assembly includes a first fixed plate 4, which is fixedly connected to the cover shell 1. A first observation port 5 is provided on the surface of the first fixed plate 4. A plurality of first sliders 6 are fixedly provided on the outside of the first fixed plate 4. A swivel 7 is movably provided on the outside of the plurality of first sliders 6. A first chute 8 is provided on the inside of the swivel 7. The first sliders 6 are slidably connected to the first chute 8. A plurality of arcuate grooves 9 are provided on the surface of the swivel 7. The cross-section of one side of the plurality of arcuate grooves 9 is configured to be cross-shaped. A second slider 10 is slidably provided inside the arcuate groove 9. The arcuate groove 9 is provided so that the second slider 10 can move in the corresponding position and drive the slide plate 11 to move linearly.

[0035] In some embodiments, according to Figure 4 As shown, a slide plate 11 is fixed to the bottom of the second slider 10, and a second fixing plate 12 is fixed to the bottom of the first fixing plate 4. A plurality of second chute grooves 13 are formed on the surface of the second fixing plate 12, and the plurality of second chute grooves 13 are slidably connected to the second slider 10. The slide plate 11 is provided to cooperate with the movement of the second slider 10, pushing the connecting plate 16 outward to increase the diameter, and the second chute grooves 13 are provided to facilitate the movement of the slide plate 11.

[0036] In some embodiments, according to Figure 3 and Figure 4 As shown, the second fixed plate 12 has a second viewing port 14 formed on its surface, and second chutes 13 are arranged around the second viewing port 14. A spring 15 is fixed to one end of the slide 11. The purpose of providing the spring 15 is to provide an elastic force when the slide 11 moves, thereby tightening the device after the utility model is installed on the flow meter.

[0037] In some embodiments, according to Figure 5 As shown, one end of the spring 15 is fixedly connected to the second slide 13, and the other end of the slide 11 is fixedly provided with a connecting plate 16. The connecting plate 16 is provided for the portability of the movement of the entire device.

[0038] In some embodiments, according to Figure 6 and Figure 7 As shown, both sides of the connecting plate 16 are hinged with outer plates 17, and two connecting rods 18 are fixedly provided on the inner side of the outer plates 17. The outer plates 17 are hinged so that when the connecting plate 16 drives the outer plates 17 to move outward, the outer plates 17 can be opened to both sides.

[0039] In some embodiments, according to Figure 7 As shown, a spherical slider 19 is fixed to one end of each of the two connecting rods 18. An inner plate 20 is movably provided outside the spherical slider 19. Two third sliding grooves 21 are formed on the surface of the inner plate 20. Both third sliding grooves 21 are slidably connected to the spherical slider 19. The purpose of providing the connecting rods 18 and spherical sliders 19 is to increase the length of the slider and prevent the overall structure from getting stuck due to curvature problems.

[0040] In some embodiments, according to Figure 8 and Figure 9 As shown, a retractable band 22 is fixedly provided at the bottom of the connecting plate 16, and a splicing thread shell 23 is fixedly provided at one end of the retractable band 22. A nut 24 is provided on the outer thread of the splicing thread shell 23. The splicing thread shell 23 and the nut 24 are provided to facilitate installation, and the retractable band 22 is provided to ensure that the utility model is fixed and stable after installation.

[0041] Working principle of the utility model: When the flow measuring instrument needs to be protected, the staff holds the cover shell 1 and the swivel 7 respectively, and by rotating the swivel 7, the swivel 7 will rotate around the first fixed plate 4 due to the action of the first slider 6 on the first fixed plate 4 and the first sliding groove 8 provided on the inner side of the swivel 7;

[0042] As the swivel 7 rotates, the second slider 10 slides along the arc groove 9 provided on the surface of the swivel 7. The sliding of the second slider 10 drives the slide plate 11 to slide along the second slide groove 13 on the second fixed plate 12. The slide plate 11 pulls the spring 15, giving the spring 15 an elastic force. Then, the slide plate 11 pushes the connecting plate 16 to move outward while sliding outward. The connecting plate 16 drives the left and right outer plates 17 to move outward at the same time. At this time, the inner plate 20 moves to both sides under the action of the spherical slider 19 and the third slide groove 21.

[0043] When the size is just right for the flow measuring instrument that needs to be protected, the observation slot 2, the first observation port 5 and the second observation port 14 of the present invention are aligned with the display screen of the flow measuring instrument and then placed on the surface of the flow measuring instrument. At this time, the staff releases their hands, because the elastic force of the previous spring 15 makes the present invention rebound and adhere to the flow measuring instrument;

[0044] Finally, the spliced ​​thread shell 23 on the tail telescopic belt 22 of the utility model is fixed tightly by the nut 24, and the cover plate 3 is covered.
