DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects of the present application more clearly understood, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application. The methods used in the present application are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.​​

[0026] As shown by Figure 3 、 Figure 4 The utility model provides a protective cover 1 for lathe, the protective cover 1 is the protective cover of organ type, it is equipped with two mounting plate 11, skeleton piece 13 and the coating cloth 14 that can fold, the protective cover 1 is equipped with support connecting plate 12, support connecting plate 12 is n-shaped structure, support connecting plate 12 is set between two mounting plate 11, and the number is two, and support connecting plate 12 is connected with the skeleton piece 13 adjacent thereto through coating cloth 14, the lateral wall of support connecting plate 12 is equipped with injection through hole 15, and the opening of injection through hole 15 is detachably installed with plug 16, and the other end of injection through hole 15 leads to the bottom surface of support connecting plate 12, wherein, support connecting plate 12 is as the connecting support piece of the adjacent skeleton piece 13 and its coating cloth 14, and the number can be set one or more according to actual conditions.

[0027] The working principle of the utility model is as follows: as shown by Figure 3 、 Figure 8 Before use, the bottom end of mounting plate 11, skeleton piece 13 and support connecting plate 12 is set in the guide groove 25 of the bottom plate 24 on the two sides of track 23, and the extension direction of the guide groove 25 is parallel to track 23. According to actual conditions, pull out the coating cloth 14, connect one mounting plate 11 with the moving part on track 23, and connect the other mounting plate 11 with the machine tool, so that the whole track 23 is covered in the protective cover 1 of the utility model, the installation work is completed, and the track 23 is completely isolated from the outside world. Open the plug 16, inject appropriate amount of lubricating liquid into the injection through hole 15, form a layer of lubricating liquid between the support connecting plate 12, skeleton piece 13 and the bottom surface of the guide groove 25 together with the coating cloth 14, and then cover the plug 16; the lubricating liquid reduces friction and noise, and the lubricating liquid film isolates the track 23 from the outside world to a certain extent.

[0028] In use, the support connecting plate 12, skeleton piece 13 and coating cloth 14 are in sliding friction state between the bottom surface of the guide groove 25 during the extension and retraction of the protective cover 1; compared with the prior art, the utility model does not set up vulnerable parts such as hinge shaft of roller one 7, roller two 8 and shear frame 9, prolonging the service life.

[0029] Furthermore, compared to existing accordion-style protective covers where the space between the two mounting plates 11 is entirely composed of skeleton pieces 13 and foldable coated fabric 14, this invention features supporting connecting plates 12, which can also alter the extension and retraction rhythm of the protective cover. The number of supporting connecting plates 12, matching the number of skeleton pieces 13, the spacing between multiple supporting connecting plates 12, and the counterweight of the supporting connecting plates 12 can be adjusted according to actual usage requirements. This technology is currently under development. Operators also need to regularly inspect the protective cover, including checking the contact between the bottom ends of the mounting plates 11, skeleton pieces 13, and supporting connecting plates 12 and the guide grooves 25, as well as the lubrication status of the lubricant, and perform regular maintenance.

[0030] In some embodiments, by Figure 5 As shown, the bottom surface of the support connecting plate 12 preferably has a straight groove 17. The extension direction of the straight groove 17 is the same as the extension direction of the protective cover 1, and the straight groove 17 is connected to the injection hole 15. The straight groove 17 serves two purposes: firstly, when injecting lubricating fluid into the injection hole 15, it is easier to use the straight groove 17 as an output channel, allowing the lubricating fluid to flow more smoothly between the bottom surface of the support connecting plate 12, the skeleton piece 13, and the coated cloth 14 and the guide groove 25, forming a layer of lubricating fluid; secondly, during use, this invention forms a stable lubricating oil film between the bottom surface of the support connecting plate 12 and the bottom surface of the guide groove 25, improving the sliding friction state between the support connecting plate 12, the skeleton piece 13, and the coated cloth 14 and the bottom surface of the guide groove 25.

[0031] In some embodiments, by Figure 4 As shown, a crossbeam 18 is preferably installed inside the support connecting plate 12. The top of the support connecting plate 12 has a ridge-like structure, and the crossbeam 18 and the top of the support connecting plate 12 form a triangular structure. The triangle has stability, which ensures that the support connecting plate 12 remains stable after long-term use, thus extending its service life.

[0032] In some embodiments, by Figure 6 As shown, a transverse support member 19 is preferably installed inside the skeleton piece 13. The top of the skeleton piece 13 has a ridge-like structure, and the transverse support member 19 and the top of the skeleton piece 13 form a triangular structure. The triangle has stability, so that the skeleton piece 13 remains stable after long-term use, thus extending its service life.

[0033] In some embodiments, by Figure 7 As shown, the side wall of the mounting plate 11 preferably has a vent 20, and a filter 21 is detachably installed inside the vent 20. The filter 21 is used to filter impurities. This ensures that the internal air pressure of the protective cover 1 remains relatively consistent with the external air pressure during the extension and retraction process, preventing excessive pressure difference between the inside and outside of the protective cover 1 and the resulting unstable fluctuations.

[0034] In some embodiments, the installation plate 11 is preferably made of a high-temperature-resistant and corrosion-resistant material, which is a prior art, prolonging the service life of the installation plate 11. Figure 7 As shown in the drawings, the outer surface of the installation plate 11 is preferably provided with mounting holes 22, so that the utility model is convenient to install and disassemble.

[0035] In some embodiments, the top of the installation plate 11, the support connecting plate 12 and the skeleton sheet 13 is preferably a ridge type structure, which is convenient to clean when impurities fall on the top of the installation plate 11, the support connecting plate 12 and the skeleton sheet 13. Figure 1

[0036] In some embodiments, the coating cloth 14 is preferably made of a high-temperature-resistant and corrosion-resistant material, which is a prior art, prolonging the service life of the coating cloth 14.

[0037] In the description of the utility model, it is understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements must have a specific orientation, structure and operation, therefore it cannot be understood as a limitation of the utility model.

[0038] The above is only the preferred embodiment of the present application, and is not intended to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
