[0021] 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.

[0022] Reference Figure 1 and Figure 2The utility model provides an embodiment: a flow measurement instrument protection cover structure, including a meter body 1, a connecting frame 2 is fixedly connected to the upper surface of the meter body 1, a connecting platform 3 is fixedly connected to the side wall of the connecting frame 2, a turning handle 4 is rotatably connected inside the connecting platform 3, a turning handle 4 is fixedly connected to one end of a rotating column 5, a connecting shaft 6 is rotatably connected inside the rotating column 5, a turning table 7 is rotatably connected to the outer wall of the connecting shaft 6, a screw 8 is threadedly connected inside the turning table 7, the outer wall of the screw 8 is rotatably connected to the inside of the turning column 5, a turning rod 9 is fixedly connected to the side wall of the turning table 7, a connecting ball 10 is rotatably connected to the bottom of the turning rod 9, a sweeping brush 12 is fixedly connected to the side wall of the connecting ball 10, a sliding box 11 is fixedly connected to the side wall of the connecting frame 2, the sweeping brush 12 is slidably connected inside the sliding box 11, and a sliding component is arranged on the top of the meter body 1.

[0023] Specifically, by turning the handle 14, the handle 14 rotates inside the connecting platform 13 and drives the rotating column 5 at one end thereof to rotate synchronously. The rotation of the rotating column 5 is transmitted to the connecting ball 10 through the transmission of the rotating rod 9, and then a push-pull force is applied to the sweeping brush 12, so that the sweeping brush 12 slides inside the sliding box 11, so that it can effectively remove surface dirt. At the same time, by turning the screw 8, the turntable 2 7 threadedly connected thereto will move, that is, it rotates on the outer wall of the connecting shaft 6 and changes its own inclination angle. The design of this mechanism changes the angle of the turntable 2 7, and then the angle of the rotating rod 9 changes accordingly, so that the rotation amplitude of the connecting ball 10 changes, and then the size of the push-pull force on the sweeping brush 12 is adjusted, ensuring a moderate force during the cleaning process, which can effectively remove dirt without damaging the surface of the protective cover or the instrument structure. This flexible adjustability makes the cleaning process suitable for measuring instruments of different types and sizes, easy to operate, with significant cleaning effects, and high applicability and adjustability.

[0024] Reference Figure 3 The sliding assembly includes a slider 13, which is slidably connected to the side wall of the watch body 1, and a rotating shaft 14 is rotatably connected inside the slider 13. A spiral coil 16 is fixedly connected to the outer wall of the rotating shaft 14, and a turning handle 2 15 is fixedly connected to the side wall of the rotating shaft 14. The spiral coil 16 is threadedly connected inside the slider 13, and a connecting column 17 is rotatably connected to the side wall of the slider 13. A connecting rod 18 is fixedly connected to the side wall of the connecting column 17, and a clamping plate 19 is fixedly connected to the side wall of the connecting rod 18. The side wall of the connecting rod 18 is rotatably connected to a connecting rod 20, and the side wall of the connecting rod 20 is rotatably connected to a connecting rod 3 21, and the side wall of the connecting rod 3 21 is rotatably connected to a rotating wheel 22, and the rotating wheel 22 is rotatably connected to the side wall of the watch body 1.

[0025] Specifically, the second handle 15 is rotated, and its rotation drives the rotating shaft 14 to rotate at the same time. The rotation of the rotating shaft 14 drives the spiral coil 16 on its outer wall to rotate synchronously. Through the threaded connection between the spiral coil 16 and the slider 13, the slider 13 is stressed and slides on the side wall of the meter body 1. The sliding of the slider 13 also causes the connecting column 17 on its side wall to rotate. The rotation of the connecting column 17 affects the connecting rod 18, causing the side wall to rotate synchronously and change its own inclination angle. Multiple connecting rods 3 21 rotate on the side wall of the rotating wheel 22, and drive the connecting rod 2 20 to rotate as well. As the connecting rod moves, the clamping plate 19 is clamped relative to the protective cover. This clamping force can be controlled by adjusting the degree of rotation of the rotating wheel 22, so as to ensure that the protective cover is appropriately fixed and not too tight or too loose. This structural design effectively fixes the protective cover to prevent moisture, dust and other substances from damaging the flow meter. Through the adjustable clamping force, the protective cover can be firmly maintained in the desired position, ensuring the normal operation and accurate measurement of the instrument. This design not only improves the protective function of the protective cover, but also enhances the protection of the instrument and prolongs its service life.

[0026] Working principle: when the protective cover needs to be cleaned on the surface, first turn the handle 4. The handle 4 rotates inside the connecting platform 3 and drives the rotating column 5 at one end to rotate synchronously. When the rotating column 5 rotates, the connecting ball 10 at the bottom of the rotating rod 9 is driven to rotate through the transmission of the rotating rod 9, thereby applying a push-pull force to the sweeping brush 12 so that the sweeping brush 12 slides inside the sliding box 11. At the same time, by rotating the screw 8, the turntable 7 threadedly connected thereto will move, that is, it will rotate on the outer wall of the connecting shaft 6 and change its own inclination angle. The change in the angle of the turntable 7 causes the angle of the rotating rod 9 to change accordingly, thereby changing the rotation amplitude of the connecting ball 10, and changing the push-pull force on the sweeping brush 12. Due to this structure, the protective cover can effectively clean the surface dirt, and the cleaning range can be freely adjusted, thereby improving the protection function of the protective cover. And for the readability of the instrument, when the protective cover needs to be fixed, turn the handle 2 15. When the handle 2 15 is rotated, the rotating shaft 14 at one end thereof rotates accordingly. The rotation of the rotating shaft 14 drives the spiral coil 16 on its outer wall to rotate synchronously. Through the threaded connection relationship between the spiral coil 16 and the slider 13, the slider 13 is forced to slide on the side wall of the meter body 1. When the slider 13 slides, the connecting column 17 of its side wall can rotate on its side wall. Through the rotation of the connecting column 17, the connecting rod 1 18 rotates synchronously on its side wall and changes its own inclination angle. At this time, multiple connecting rods 3 21 rotate on the side wall of the wheel 22 and drive the connecting rod 2 20 to rotate as well, so that the clamping plate 19 relatively clamps the protective cover. The protective cover is further effectively fixed by this structure to prevent moisture, dust and other substances from damaging the flow meter, thereby improving the protection function of this protective cover.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
