DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0033] With reference to Figure 1 , Figure 3 and Figure 5 , the utility model provides an embodiment: replaceable ultrasonic probe protective sleeve, including casing 1, casing 1 provides protection for internal element, the outside fixed connection of casing 1 has annular block 2, annular block 2 provides installation space for the tightening assembly of protective film 10 tightening, the inside top of annular block 2 is equipped with sliding slot 3, sliding slot 3 provides sliding space for sliding block 4, the inside sliding connection of sliding slot 3 has sliding block 4, sliding block 4 drives annular plate 6 to slide and extrudes protective film 10, the inside of annular block 2, i.e. the left side of sliding block 4 is equipped with limiting slot 5, when tightening is completed, sliding block 4 slides to the inside limiting slot 5 and is fixed in position;

[0034] The bottom of sliding block 4 is fixedly connected with annular plate 6, and annular plate 6 is used for extruding and tightening the protective film, a placing groove 7 is formed in the inside of annular block 2, the placing groove 7 is used for placing rubber ring 9 in the inside thereof to facilitate the extrusion of annular plate 6 on protective film 10, an extrusion groove 8 is formed in the inside of annular block 2, i.e. the front side of annular plate 6, then annular plate 6 drives protective film 10 to move to the inside of placing groove 7 for tightening, and the inside of placing groove 7 is detachably connected with rubber ring 9.

[0035] With reference to Figure 1 , Figure 2 and Figure 4 , the rubber ring 9 is placed in the inside of the placing groove 7, facilitating the extrusion and tightening of the annular plate 6 on the protective film 10, the outside of the rubber ring 9 is sleeved with the protective film 10, the protective film 10 is used for protecting the outside of the casing 1 and preventing pollution, the top rear side of the casing 1 is fixedly connected with a base block 11, the base block 11 provides mounting space for an air suction assembly, the top of the base block 11 is fixedly connected with an air suction assembly for sucking air in the inside of the protective sleeve, the air suction assembly comprises an air bag 12, the air bag 12 is used for realizing the air suction function in the inside of the protective sleeve 10, air vents 13 are formed in the inside of the air bag 12 on the front and rear sides, and the air vents 13 are used for air exchange of the air bag 12.

[0036] The inner wall of the air exchange port 13 is fixedly connected with an air exchange pipe 14, which ensures smooth circulation of gas between the air bag 12 and the outside. The inner wall of the air exchange pipe 14 is rotatably connected with a rotating plate 15, which is pressed by the air bag 12. After the air bag 12 is pressed, the internal air pressure changes, driving the rotating plate 15 to rotate. The inner wall of the air exchange pipe 14, i.e. the front side of the rotating plate 15, is fixedly connected with a limiting block 16, which is used to limit the rotation of the rotating plate 15. Whether it is air extraction or air intake, only one side of the rotating plate 15 can rotate.

[0037] Referring to Figures 2 to 4 The outer part of the sliding block 4 is slidably connected inside the limiting groove 5. When the sliding block 4 slides to the inside of the limiting groove 5, it completes the limiting and fixing of the annular plate 6. The outer part of the annular plate 6 is in contact with the inner wall of the extrusion groove 8. The annular plate 6 moves to the inside of the extrusion groove 8, completing the extrusion and tightening of the protective film 10. The outer bottom of the sliding block 4 is slidably connected inside the annular plate 6. When the sliding block 4 can only slide left and right inside the annular plate 6, it is convenient for the sliding block 4 to slide to the inside of the limiting groove 5. The rubber ring 9 is placed inside the placing groove 7 to facilitate the fixing of the protective film 10. The annular plate 6 directly pushes the protective film 10 to slide and tighten. By pushing the sliding block 4 to drive the annular plate 6 to slide, the protective film 10 is contracted. Pushing the sliding block 4 to drive the annular plate 6 to slide makes the annular plate 6 tighten the protective film 10;

[0038] After the protective film 10 is contracted, the sliding block 4 slides to the inside of the limiting groove 5 for limiting and fixing. Since the sliding block 4 can only slide left and right inside the annular plate 6, when the protective film 10 is tightened, the sliding block 4 slides to the left to the inside of the limiting groove 5 for limiting and fixing. The front side of one of the air exchange pipes 14 is fixedly connected with an air suction pipe 17, which is used to transmit the gas inside the protective film 10. The inside of the shell 1 is provided with an air suction hole 18. As above, the air suction hole 18 cooperates with the air suction pipe 17 to complete the absorption of the gas inside the protective film 10. The outer front side of the air suction pipe 17 is fixedly connected to the inner wall of the air suction hole 18. The air inside the protective film 10 can enter the air suction pipe 17 through the air suction hole 18. The rear side of the shell 1 is fixedly connected with a power cord 19, which is used to power the device;

[0039] Pressing the air bag 12 opens one of the rotating plates 15, i.e. the rear side of the air bag 12, to exhaust air. When the air bag 12 is pressed, the gas pressure inside the air bag 12 increases, pushing the rotating plate 15 at the rear side of the air bag 12 to rotate to exhaust air. The rotating plate 15 at the front side cannot rotate due to the limiting block 16 and can only exhaust air. The air bag 12 resets to exhaust air inside the protective film 10 through the rotating plate 15 at the front side of the air bag 12. When the air bag 12 resets, the gas pressure inside the protective film 10 is greater than the pressure inside the air bag 12, causing the rotating plate 15 at the front side of the air bag 12 to open under the action of the pressure difference. The gas inside the protective film 10 enters the air bag 12 through the air suction pipe 17.

[0040] Working principle: When the rubber ring 9 is placed in the groove 7, the protective film 10 needs to be tightened. Push the sliding block 4 in the sliding groove 3 of the annular block 2. The sliding block 4 drives the annular plate 6 to move synchronously, and then the annular plate 6 slides along the inner wall of the extrusion groove 8 to extrude the protective film 10. The movement of the annular plate 6 tightens the protective film 10 in the direction of the extrusion groove 8. When the protective film 10 is tightened, continue to push the sliding block 4 to the inside of the limiting groove 5, so as to limit and fix the annular plate 6, and then make the protective film 10 tightly adhere to the annular block 2, complete the tightening operation of the protective film 10, and provide a reliable protective barrier for the ultrasonic probe to prevent external pollutants from contacting the probe.

[0041] When the air inside the protective film 10 needs to be pumped, press the air bag 12, and the gas pressure inside the air bag 12 changes, causing the rotating plate 15 at the rear side of the air bag 12 to rotate, so that the opening of the rotating plate 15 allows the gas inside the air bag 12 to be exhausted. When the air bag 12 resets, the gas pressure inside the protective film 10 is greater than the pressure inside the air bag 12, and the pressure difference causes the rotating plate 15 on the inner wall of the front side of the air exchange pipe 14 to open. The air inside the protective film 10 enters the air suction pipe 17 through the air suction hole 18, and then enters the air bag 12 through the air exchange pipe 14, achieving the purpose of exhausting the air inside the protective film 10, so that the protective film 10 can better adhere to the ultrasonic probe, reducing the adverse effects of air on ultrasonic detection, and improving the accuracy and stability of detection.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
