[0025] The dust cover body 1 is made of nylon material, which has good wear resistance, impact resistance and corrosion resistance, and can effectively prevent the dust cover body 1 from being damaged. By connecting the adjusting component to the inflation device, the sealing degree between the adjusting component and the protected component can be controlled by the input gas volume, so that the rubber dust cover can adapt to protected objects of different sizes. The adjusting component is fixed by the fixing component so that the adjusting component will not be displaced during use, and the installation and disassembly of the adjusting component is convenient.
[0026] Reference Figure 2 and Figure 3 The adjustment component includes an airbag 16, the outer side of the airbag 16 is in contact with the outer side of the placement groove 14 on the same side, and a number of connecting blocks 17 are fixedly connected to the outer side of the airbag 16 at equal distances. The outer sides of the several connecting blocks 17 are fixedly connected to a number of fixing rings 18. A pinhole-type air inlet hole 19 is opened in the middle of the outer end of the connecting block 17. The connecting blocks 17 pass through the adjacent through grooves 15 respectively. The fixing rings 18 are all located on the outside of the fixing ring 3, and the pinhole-type air inlet holes 19 are all connected to the inside of the airbag 16.
[0027] Insert the inflation needle into any pinhole-type air inlet hole 19 and inflate the interior. The gas enters the interior of the airbag 16 through the pinhole-type air inlet hole 19 to expand the airbag 16, so that the airbag 16 fits closely with the protected object without a gap. In this way, the sealing degree between the inner side of the airbag 16 and the protected object is adjusted, so that the airbag 16 can be suitable for dust protection of protected objects of different sizes.
[0028] Reference Figure 1 、 Figure 3 and Figure 4The two fixing components are symmetrical. The upper fixing component includes two L-shaped plates 4, a limiting ring 1 7 and a limiting ring 2 10. The adjacent ends of the bottom of the two L-shaped plates 4 are fixedly connected to the left and right ends of the top of the fixing ring 3 respectively. The bottom of the L-shaped plate 4 is rotatably connected to the end away from the two-way threaded column 5. The middle of the two-way threaded column 5 is fixedly connected to a swivel 6. The left and right ends of the limiting ring 1 7 are fixedly connected to a moving block 1 8. The bottom end of the limiting ring 1 7 is fixedly connected to several splints 1 9 at equal distances. The left and right ends of the limiting ring 2 10 are fixedly connected to a moving block 2 11. The top of the limiting ring 2 10 is fixedly connected to several splints 2 12 at equal distances. The positions of several splints 2 12 and several splints 19 are all connected The positions of the blocks 17 correspond, and the opposite ends of the splint 2 12 and the splint 1 9 are provided with several limiting grooves 13. When the splint 2 12 is fitted with the opposite end of the splint 1 9 on the same side, the inner sides of the splint 2 12 and the splint 1 9 are respectively fitted with the upper and lower sides of the connecting block 17, and several limiting grooves 13 are engaged with the adjacent fixing rings 18 on the same side. The bottom ends of the two-way threaded columns 5 are rotatably connected to the top of the fixed plate 2, and the middle parts of the two moving blocks 18 are respectively threadedly connected to the middle and upper parts of the two-way threaded columns 5 on the same side, and the middle parts of the two moving blocks 2 11 are respectively threadedly connected to the middle and lower parts of the two-way threaded columns 5 on the same side. The inner sides of the limiting ring 1 7 and the limiting ring 2 10 are both slidably connected to the outer side of the fixing ring 3, and the inside and outside of the dustproof sleeve 1 are both corrugated.
[0029] The thread directions of the two bidirectional threaded columns 5 are opposite. When the swivel 6 is rotated inward at the same time, the moving block 18 can be driven to move upward on the outside of the bidirectional threaded column 5 on the same side, thereby driving the limit ring 17 to move upward, and the moving block 2 11 can be driven to move downward on the outside of the bidirectional threaded column 5 on the same side, thereby driving the limit ring 2 10 to move downward. When the limit ring 17 moves upward, it drives the splint 1 9 to disengage from the upper outer part of the connecting block 17, and the limit ring 2 10 moves downward to drive the splint 2 12 to disengage from the lower outer part of the connecting block 17. When the swivel 6 is rotated outward at the same time, the limit ring 1 7 and the limit ring 2 10 can be driven to move relative to each other, so that the opposite side of the splint 1 9 and the splint 2 12 are in contact with the outer side of the airbag 16, and the limiting groove 13 is engaged with the corresponding airbag 16, thereby fixing the connecting block 17 to prevent the displacement of the connecting block 17 from affecting the overall sealing of the protective cover when the airbag 16 is in use.
[0030] Working principle: By inserting an air needle into the pinhole air inlet hole 19 on any connecting block 17 and inflating the interior, the gas enters the interior of the airbag 16 through the pinhole air inlet hole 19 to expand the airbag 16, so that the airbag 16 fits closely with the protected object without a gap, thereby preventing dust and the like from entering the surface of the protected object and affecting the movement of the protected object. When the airbag 16 is damaged, the swivel 6 can be rotated at the same time to rotate the two bidirectional threaded columns 5, driving the limit ring 1 7 and the limit ring 2 10 to move in opposite directions, so that the opposite side of the splint 1 9 and the splint 2 12 are disengaged from the corresponding connecting block 17, and the limit groove 13 is disengaged from the corresponding fixing ring 18, and then the connecting block 17 is moved toward the inside of the fixing ring 3 until there is no contact between the connecting block 17 and the through groove 15. The airbag 16 can be taken out of the fixing ring 3 and replaced.
[0031] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
