Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0024] The dustproof structure of a dustproof cover with a pressing spring on the inner diameter according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a dustproof structure of a dustproof cover with a pressing spring on the inner diameter, comprising a mounting frame 1, a first dustproof member 2 and a mounting plate 3, wherein the first dustproof member 2 is mounted between the top of the mounting frame 1 and the bottom of the mounting plate 3, and a blocking mechanism is arranged inside the mounting frame 1;

[0027] The blocking mechanism includes a fixed ring 4, four winding drums 5, four second dustproof parts 6, four mounting parts 7 and four movable parts 8. The fixed ring 4 is fixedly mounted on the inner wall of the mounting frame 1. The winding drum 5 is rotatably connected to the side wall of the fixed ring 4 through a torsion spring. One end of the second dustproof part 6 is wound on the side wall of the winding drum 5, and the other end of the second dustproof part 6 is fixedly mounted on one side of the mounting part 7. A movable groove 9 is opened inside the mounting part 7, and one end of the movable part 8 is slidably connected inside the movable groove 9.

[0028] It should be noted that the two ends of the movable part 8 slide inside two adjacent mounting parts 7 respectively, and the four mounting parts 7 and the four movable parts 8 form a ring part. By arranging the mounting parts 7 and the movable parts 8 inside the mounting frame 1, the circle formed by the mounting parts 7 and the movable parts 8 can fit the side wall of the object as much as possible, thereby reducing the shaking of the dust cover. By cooperating with the second dustproof part 6, the gap between the bottom of the dust cover and the object can be reduced, thereby improving the dustproof effect.

[0029] In some embodiments, Figure 2 As shown, the second dust-proof member 6 is a fan-shaped member.

[0030] It should be noted that the second dustproof member 6 is an elastic membrane, and the gap can be reduced as much as possible by setting the second dustproof member 6 to be fan-shaped.

[0031] In some embodiments, Figure 3 As shown, a guide rail 10 is fixedly installed on the inner wall of the movable groove 9, one end of the movable part 8 is slidably connected to the side wall of the guide rail 10, a tension spring 11 is installed inside the movable groove 9, the tension spring 11 is arc-shaped, and the tension spring 11 is fixedly installed between two adjacent movable parts 8, and the tension spring 11 is located inside the movable groove 9.

[0032] It should be noted that the sliding range of the movable part 8 can be limited by setting the guide rail 10, and the two adjacent movable parts 8 can be pulled toward the center of the mounting part 7 by setting the tension spring 11, so that the diameter of the circle formed by the mounting part 7 and the movable part 8 can be automatically reduced to reduce the gap after installation.

[0033] Example 2

[0034] In some embodiments, Figure 4 As shown, the first dustproof member 2 is in the shape of a bellows, a first pressing spring 12 is fixedly installed on the inner wall of the outer ring of the first dustproof member 2, and a second pressing spring 13 is fixedly installed on the inner wall of the inner ring of the first dustproof member 2.

[0035] It should be noted that, by installing the first urging spring 12 and the second urging spring 13 on the inner wall of the first dustproof member 2, the first dustproof member 2 can be supported to avoid deformation of the first dustproof member 2, thereby achieving a better dustproof effect.

[0036] Working principle: When in use, the mounting frame 1 is put on the outside of the object, so that the mounting frame 1 is located at the bottom of the object, the first dustproof part 2 is located on the side wall of the object, and the mounting plate 3 is located on the top of the object. Then, the two adjacent movable parts 8 are pulled toward the center of the mounting part 7 through the tension spring 11, so that after installation, the diameter of the circle formed by the mounting part 7 and the movable part 8 can shrink by itself to reduce the gap. By setting the second dustproof part 6 to a fan shape, the gap can be reduced as much as possible to reduce the entry of dust.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
