[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-4As shown, a machine tool protection device includes a protection shell 1, a protection component 7 is arranged on the front side of the protection shell 1, two visual glass windows 4 are arranged on the upper end of the front side of the protection shell 1, sliding grooves 3 are opened on the upper end of the front side of the protection shell 1 and the upper and lower sides of the visual glass windows 4, a cleaning component 5 is arranged between the two sets of sliding grooves 3, a ventilation tube 2 is fixedly connected to the left side of the top of the protection shell 1, the left and right sides of the protection shell 1 are rotatably connected to side panels 8 through hinges, side windows 10 are fixedly installed in the middle of the two side panels 8, first handles 9 are fixedly connected to the front sides of the outer surfaces of the two side panels 8, and a fixing bolt 6 for fixing the protection component 7 is installed on the left side of the front side of the protection shell 1.

[0024] Specifically, the cleaning component 5 includes two connecting rods 503, which are respectively slidably connected to the inside of the two groups of sliding grooves 3. The connecting rod 503 is fixedly connected to one end of the outer side of the protective shell 1 with a first scraper 501, and the upper surface of the first scraper 501 is fixedly connected with a second handle 502. Through the design of sliding the connecting rod 503 in the sliding groove 3, the user can easily operate the first scraper 501 and the second scraper 504 to clean the inside and outside of the visible glass window 4 without disassembling any parts, thereby improving the cleaning efficiency.

[0025] Specifically, the connecting rod 503 is fixedly connected to one end of the inner side of the protective shell 1 with a second scraper 504, and bristles are provided on the first scraper 501 and the second scraper 504 on the side close to the visible glass window 4. The surface of the connecting rod 503 is fixedly connected to the outer side of the protective shell 1 with a limiting block 505, and the limiting block 505 is slidably connected to the outer surface of the protective shell 1. The setting of the limiting block 505 prevents the connecting rod 503 from derailing during sliding, thereby ensuring stability and safety during the cleaning process. The bristle design on the first scraper 501 and the second scraper 504 ensures that the visible glass window 4 is cleaned from both the inside and the outside, effectively removing dust and stains and maintaining a clear field of vision.

[0026] Specifically, the protective component 7 includes two movable slide rails 701, which are respectively fixedly connected to the upper and lower sides of the protective shell 1. A first protective plate 703 is arranged on the left side between the two movable slide rails 701. The first protective plate 703 is slidably connected to the movable slide rail 701 through a first slider 702. All protective plates are slidably connected to the movable slide rail 701 through sliders, so that users can quickly adjust the position and number of protective plates according to the specific needs of machine tool operation, thereby improving the flexibility of use.

[0027] Specifically, the first protective plate 703 is slidably connected to the inside of the second protective plate 704, and the second slider 705 is fixedly connected to the upper and lower sides of the right end of the second protective plate 704, and the second slider 705 is slidably connected to the movable slide rail 701. The third protective plate 706 is slidably connected to the inside of the second protective plate 704, and the third slider 707 is fixedly connected to the upper and lower sides of the right end of the third protective plate 706, and the third slider 707 is slidably connected to the movable slide rail 701. Through the stacking design of the first protective plate 703, the second protective plate 704 and the third protective plate 706, a variety of protection area options are provided, and the protection area can be adjusted according to actual needs to enhance the protection effect of the machine tool. In order to prevent the first protective plate 703, the second protective plate 704 and the third protective plate 706 from falling off each other, blocks are set on the left sides of the second protective plate 704 and the third protective plate 706 for limiting the position (not drawn in the figure).

[0028] Specifically, a magnetic block 709 is fixedly connected to the inside of the right side of the third protective plate 706, and a third handle 708 is fixedly connected to the front right end of the third protective plate 706. The magnetic block 709 is not only used to assist in closing, but also can provide a certain locking force when closing, to prevent the protective plate from opening accidentally, thereby enhancing the safety of the protective device.

[0029] Specifically, the first rotating support 710 is fixedly connected to the left inner wall of the first protective plate 703, the right side of the first rotating support 710 is rotatably connected to a scissor-type connecting strip 711, the right side of the scissor-type connecting strip 711 is rotatably connected to a second rotating support 712, and the second rotating support 712 is fixedly connected to the left side wall of the magnetic block 709. The combined design of the scissor-type connecting strip 711, the first rotating support 710 and the second rotating support 712 ensures that when the third protective plate 706 is pulled open, the scissor-type connecting strip will naturally open.

[0030] Working principle: When opening the protective assembly 7, first hold the third handle 708 and apply force to the left side so that the third protective plate 706 is stored inside the second protective plate 704, and continue to move to the left side so that the second protective plate 704 is stored inside the first protective plate 703. When the protective plates are stored, the scissor-type support strips 711 will shrink, and when opened, they will expand to improve the integrity of the first protective plate 703, the second protective plate 704 and the third protective plate 706. After the storage is completed in the above manner, the third protective plate The mechanical structure at the position of 706 and the second protective plate 704 will be exposed. When the mechanical structure at the position of the first protective plate 703 needs to be displayed, it is only necessary to loosen the fixing bolt 6, and the stored first protective plate 703, the second protective plate 704 and the third protective plate 706 can be pushed to the right along the movable slide rail 701. When cleaning the visible glass window 4, it is only necessary to hold the second handle 502 and pull the first scraper 501 along the sliding groove 3 to complete the synchronous cleaning of the inside and outside of the visible glass window 4.
