[0027] The present invention is further described in detail below in conjunction with specific implementation methods. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0028] Example 1

[0029] See also Figure 1-9In the present embodiment, a safety protection cover for a grinder is provided, comprising a mounting seat 1 and a cover body 3. The mounting seat 1 is mounted on the working table of the grinder. An avoidance groove 2 is provided in the middle of the mounting seat 1. The avoidance groove 2 is used to avoid the grinding parts of the grinder. The rear side of the mounting seat 1 is rotatably connected to the cover body 3 through a pin shaft. An inclined surface is formed on the front side of the cover body 3. An operation window 8 is provided on the inclined surface. The operation window 8 is provided on the inclined surface. When the operator's arm is in a drooping state, the operator can reach deep into the cover body 3. When operating, there is no need to lift the arm too high, which is more convenient for the user to operate and save arm strength. The cover body 3 can be rotated relative to the mounting seat 1 by the pin shaft to open the cover body 3. After opening the cover body 3, it is more convenient for the user to clean the grinding chips on the table, saving the user's cleaning time.

[0030] Fixed seats 2 7 are symmetrically arranged on both sides inside the mounting seat 1, and fixed seats 2 7 are hinged to one end of the compressed gas spring 5. Fixed seats 1 4 are arranged at both sides of the cover body 3 corresponding to the fixed seats 2 7, and the fixed seats 1 4 are hinged to the other end of the compressed gas spring 5. The compressed gas spring 5 is arranged. After the cover body 3 is opened, the compressed gas spring 5 plays a role of supporting the cover body 3. The user does not need to support the cover body 3 while cleaning, which is more convenient for cleaning of grinding chips.

[0031] A fixing block is provided at the end of the telescopic end of the compressed gas spring 5, and the fixing block is fixedly connected to the protective component 6 by screws. The protective component 6 is clamped on the outside of the compressed gas spring 5, and one end of the protective component 6 is fixed to the fixing block at the telescopic end of the compressed gas spring 5 by screws, and the other end of the protective component 6 is slidably connected to the outer cylinder of the compressed gas spring 5. The setting of the protective component 6 can prevent grinding chips from splashing onto the telescopic rod of the compressed gas spring 5, affecting the normal telescopic extension of the compressed gas spring 5, and reducing the risk of the compressed gas spring 5 getting stuck.

[0032] The protective component includes a protective shell 61, which is a U-shaped shell with closed ends. A U-shaped slot 63 is provided at one of the closed ends of the protective shell 61, and the slot 63 is clamped in the telescopic end of the compressed gas spring 5. Threaded holes are provided on the upper and lower sides of the slot 63 at the closed end, and the threaded holes are connected to the fixing block of the telescopic end of the compressed gas spring 5 through screws. A contact sleeve 62 is provided at the other closed end of the protective shell 61, and the contact sleeve 62 is a U-shaped sleeve. The contact sleeve 62 contacts the outer cylinder of the compressed gas spring 5 and slides relative to the outer cylinder. The setting of the contact sleeve 62 enables the protective shell 61 to slide smoothly relative to one end of the outer cylinder of the compressed gas spring 5. Because the thickness of the protective shell 61 is limited, if only a sliding groove that cooperates with the outer cylinder of the compressed gas spring 5 is opened at its end, the sliding groove may scratch the outer cylinder of the compressed gas spring 5, resulting in uneven relative sliding and easy scratching of the outer cylinder of the compressed gas spring 5.

[0033] The lower end of the cover body 3 is laterally bent inward to form a bent portion, and the formed bent portion can increase the contact surface between the bottom of the cover body 3 and the mounting seat 1, so that the cover body 3 is more stable after closing.

[0034] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
