Description

Technical Field

[0001] The utility model relates to the technical field of industrial protective devices, in particular to a multi-purpose dust cover with adjustable size. Background Art

[0002] In industrial production, dust covers have many functions, such as covering the exposed operating mechanisms of various large-scale equipment. This not only protects the operating mechanisms of the equipment from the influence of external dust, but also plays an isolating and protective role for the staff, and at the same time increases the aesthetics. The accordion dust covers currently used are stretchable and adjustable for dust protection through their own expansion and contraction. However, because the protective cover structure of this dust cover is soft, a span that is too long will cause the middle to fall and collapse due to its own gravity. Therefore, the span of its use should not be too long, which makes its use limited. Moreover, the surface layer of the structure does not have the function of thermal insulation, and cannot insulate some products that require insulation. In addition, there will be a certain gap on the edge of the lower port, and the isolation at this place is not good. For this reason, we propose a multi-purpose dust cover with adjustable size.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-3As shown, a multi-purpose dust cover with adjustable size includes an accordion telescopic cover 1 and a fixing seat 5, a movable frame 2 is fixedly installed on the front port of the accordion telescopic cover 1, a fixed frame 3 is fixedly installed on the rear port of the accordion telescopic cover 1, a connecting frame 4 is connected between the accordion telescopic cover 1, an adjustment structure 6 is connected between the fixed frame 3 and the movable frame 2, and two adjustment structures 6 are provided, and metal sliding rods 7 are connected above the two adjustment structures 6 between the movable frame 2 and the fixed frame 3. When the accordion telescopic cover 1 is extended or retracted, the movable frame 2 slides on the metal sliding rod 7 through the first sliding hole 202, and similarly, the connecting frame 4 slides on the connecting frame 4 through the second sliding hole 401. A heat preservation structure 8 is fixedly installed on the inner surface of the accordion telescopic cover 1;

[0019] The front surface of the movable frame 2 is provided with thread holes 201 near both sides, and the front surface of the movable frame 2 is provided with first sliding holes 202 above the thread holes 201; the adjustment structure 6 includes a screw rod 601, a bearing 602 and a servo motor 603, the servo motor 603 is fixedly installed on the rear surface of the fixed frame 3, the output end of the servo motor 603 is connected to the screw rod 601, the front end of the screw rod 601 passes through the fixed frame 3 and the thread hole 201 and is fixedly connected to the bearing 602; the screw rod 601 is spirally connected to the movable frame 2 through the thread hole 201, and the front end of the screw rod 601 is movably installed with the fixed seat 5 through the bearing 602; the surface of the connecting frame 4 A second sliding hole 401 is opened on the surface, and the metal sliding rod 7 slides through the second sliding hole 401 and the first sliding hole 202 to be connected between the fixed seat 5 and the fixed frame 3; the thermal insulation structure 8 includes thermal insulation cotton 801, a tin foil inner liner 802 and a tin foil outer liner 803, wherein the thermal insulation cotton 801 has the functions of thermal insulation and sound insulation and noise reduction, and the tin foil inner liner 802 and the tin foil outer liner 803 have good thermal insulation effects, the thermal insulation cotton 801 is fixedly installed between the tin foil inner liner 802 and the tin foil outer liner 803, and the thermal insulation structure 8 is fixedly installed with the accordion telescopic cover 1 through the tin foil inner liner 802, and dust-proof brushes 9 are fixedly installed on the edges of both sides of the accordion telescopic cover 1.
