[0035] The terms “include,” “including,” “have,” etc. used in this document are open-ended terms, meaning including but not limited to.

[0036] The terms used in this document generally have the ordinary meaning of each term used in this field, in the context of the case and in the specific context, unless otherwise noted. Certain terms used to describe the present invention will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the present invention.

[0037] The terms "front", "back", "upper" and "lower" used in this article are directional terms. In this case, they are only used to illustrate the positional relationship between the structures and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0038] See attached Figures 1 to 6 As shown, a ceiling protection structure is arranged above a workbench, including a protective cover 1 and several supporting frame sheets 2, each supporting frame sheet 2 is arranged parallel to each other and spaced along the length direction of the protective cover 1, and each supporting frame sheet 2 is arranged vertically, and the protective cover 1 is fixedly arranged on each supporting frame sheet 2. The protective cover 1 between two adjacent supporting frame sheets 2 is repeatedly folded to form several folding sections 3, so that the protective cover 1 can be unfolded and folded by the relative approach and separation movement of adjacent supporting frame sheets 2. The folding number of the folding section 3 can be single fold or multi-fold. The multi-folding folding section 3 does not need to be additionally provided with a supporting frame sheet 2 for support, which reduces the use of the supporting frame sheet 2, thereby reducing the production cost of the ceiling protective cover, and also reducing the deadweight of the ceiling protective cover.

[0039] The undulating section 3 includes a crest-shaped structure 31 and a trough-shaped structure 32. The connecting part of two adjacent undulating sections 3 is located on the outward side of the protective cover 1 as the crest-shaped structure 31, and is located on the inward side of the protective cover 1 as the trough-shaped structure 32. Dust and liquid can fall and flow out from both sides of the protective cover 1, and are not easy to accumulate on the protective cover 1, thereby achieving the purpose of extending the service life of the protective cover 1.

[0040] A clip 4 is installed on each supporting frame piece 2. Since the protective cover 1 is fixed to the supporting frame piece 2 by sewing, bonding or welding, the clip 4 is installed and fixed to improve the supporting force of the supporting frame piece 2. At the same time, the protective cover 1 is made more stable, the protection and use effects are enhanced, and the problem that the ceiling protective cover is prone to deformation is solved.

[0041] The protective cover 1 in this embodiment is made of hard cloth, so it has high bending strength. Within a certain span range, there is no need to add additional supporting frame pieces 2 as its support. This embodiment has a simple structure and is easy to process. It not only achieves the protective effect but also effectively saves costs.

[0042] In the above scheme, inwards refers to the direction toward the workbench, and outwards refers to the direction opposite to the workbench.

[0044] Preferably, see the attached Figure 2 and attached Figure 4 As shown, in the present invention, the peak width of the wave crest structure 31 or the valley width of the wave valley structure 32 is adapted to the thickness of the support frame sheet 1 to ensure the reliability of the fixation between the protective cover 1 and the support frame sheet 2 .

[0045] Preferably, see the attached Figure 4 As shown, the clip 4 is installed on the inner side and / or outer side edge of the supporting frame sheet 2, so that the protective cover 1 can well maintain the initial shape and is not easily deformed.

[0046] Meanwhile, the clip 4 in this embodiment is a metal clip, and the metal material is a known metal material such as iron and copper that can be used to reinforce the protective cover 1 .

[0047] Preferably, see the attached Figure 6 As shown, in this embodiment, the protective cover 1 includes an outer protective cover 5 and an inner protective cover 6, and each supporting frame piece 2 is arranged parallel to each other between the outer protective cover 5 and the inner protective cover 6. The supporting frame piece 2 serves as a connecting piece between the outer protective cover 5 and the inner protective cover 6, connecting the two to ensure that the two can achieve synchronous expansion and contraction.

[0048] The outer protective cover 5 is located on the outward side of the protective cover 1. The outer protective cover 5 is repeatedly folded according to a certain width to form several retractable outer folding sections 51. A V-shaped outer wave peak structure 52 or an outer wave valley structure 53 is formed between two adjacent outer wave valley sections 51. The part where two adjacent outer wave valley sections 51 are connected is located on the outward side of the outer protective cover 5 as the outer wave peak structure 52, and is located on the inward side of the outer protective cover 5 as the outer wave valley structure.

[0049] The inner protective cover 6 is located on the inner side of the protective cover 1, and the inner protective cover 6 is also repeatedly folded according to a certain width to form a plurality of retractable inner folding sections 61. An inner wave crest structure 62 or an inner wave valley structure 63 is formed between two adjacent inner wave valley sections 61. The inner wave crest structure 62 is located on the inner side of the inner protective cover 6 at the connection point of the adjacent inner wave valley sections 61, and the inner wave valley structure 63 is located on the outer side of the inner protective cover 6. The protective cover 1 in the utility model is two-layered, and a single-layer or multi-layer protective cover can also be used. The shape of the protective cover 1 can be designed into various styles according to actual needs, and the size can be made according to actual needs.

[0050] The protective cover 1 in this embodiment has two layers, and the height of the outer protective cover 5 in the inner and outer directions is higher than the height of the inner protective cover 6 in the inner and outer directions, so that the inner protective cover 6 can be better folded into the outer protective cover 5 .

[0051] At the same time, the number of the inner undulating sections 61 is greater than the number of the outer undulating sections 51 , so that the inner protective cover 6 itself has stronger stability.

[0052] Preferably, see the attached Figures 1 to 6 As shown, in this embodiment, a first connecting plate 7 and a second connecting plate 8 are respectively bonded and fixed to the end surfaces of both ends of the protective cover 1 along the folding direction, for connecting with corresponding connecting components on the machine tool.
