[0026] The positioning structure includes a baffle 11 and a positioning sleeve 12. The baffle 11 is movably connected inside the groove 14. One end of the baffle 11 is fixedly connected to the positioning sleeve 12. One end of the groove 14 is fixedly connected to a fixed shaft 18. The fixed shaft 18 penetrates the positioning sleeve 12 and is fixedly connected to a positioning plate 20. A positioning card slot 13 is provided on one side of one end of the groove 14. A through slot 15 is provided on the top of one end of the baffle 11. A spring 16 is fixedly connected to the bottom end of the through slot 15. A positioning card block 21 is fixedly connected to the top of one end of the spring 16. A group of reinforcing ribs 17 are fixedly connected to both sides of one end of the baffle 11, and a group of fixing blocks 19 are fixedly connected to both ends of the positioning sleeve 12.

[0027] The fixing block 19 is fixedly connected to the baffle 11, and the positioning block 21 is movably connected to the positioning slot 13;

[0028] The center line of the positioning sleeve 12 and the center line of the baffle 11 are on the same vertical plane, and the fixed shaft 18 is movably connected to the positioning sleeve 12;

[0029] Specifically, Figure 1 and Figure 3 As shown, after closing the protective door, the baffle 11 can be rotated by the fixing block 19. The baffle 11 rotates and drives the positioning block 21 to move until the positioning block 21 is engaged with the positioning slot 13, thereby positioning the baffle 11 through the positioning block 21. At the same time, the baffle 11 blocks one end of the protective door and presses the protective door to prevent the protective door from vibrating, thereby improving the stability of the protective door after closing.

[0033] Specifically, Figure 1 , Figure 2 and Figure 4As shown, after closing the protective door, the protective door is attached to one end of the fixed frame 2, and the sealing strip 3 is attached to the outside of the protective door. Then, the cylinder 10 is started to push the movable plate 7 to move to one side, and the movable plate 7 drives the rubber strip 6 to attach to one side of the protective door to ensure the sealing around the protective door. This avoids the problem of reserving space due to the flipping angle of the protective door, which causes the sealing component to be unable to fully fit with the protective door, thereby improving the sealing.

[0034] Embodiment 3: A set of fixing grooves 5 are respectively provided at both ends of one end of the fixing frame 2, and a buffer pad 4 is fixedly connected inside the fixing groove 5;

[0035] The fixing grooves 5 opened at one end of the fixing frame 2 are arranged symmetrically;

[0036] Specifically, Figure 1 and Figure 4 As shown, when the protective door is closed, the protective door is attached to one end of the fixed frame 2, and the fixing groove 5 at one end of the fixed frame 2 can effectively buffer the protective door to prevent the protective door or the fixed frame 2 from being deformed due to the excessive impact force generated by the collision between the protective door and the fixed frame 2, thereby affecting subsequent use. After the protective door is closed, the fixing groove 5 is attached to one end of the protective door to prevent the protective door from vibrating, thereby achieving buffering when the protective door is closed.

[0037] Working principle: When the utility model is in use, after the protective door is closed, the baffle 11 can be rotated by the fixed block 19, and the baffle 11 drives the positioning block 21 to move while rotating, until the positioning block 21 is engaged with the positioning slot 13, so that the baffle 11 is positioned by the positioning block 21, and at the same time, the baffle 11 blocks one end of the protective door and presses the protective door to prevent the protective door from vibrating. After the protective door is closed, the protective door is attached to one end of the fixed frame 2, and the sealing strip 3 is attached to the outside of the protective door. Then, the cylinder 10 is started to push the movable plate 7 to move to one side, and the movable plate 7 drives the rubber strip 6 to fit on one side of the protective door to ensure the sealing around the protective door, avoiding the problem of the protective door flipping angle requiring to reserve space resulting in the sealing component being unable to completely fit with the protective door. When the protective door is closed, the protective door fits on one end of the fixed frame 2, and the fixed groove 5 at one end of the fixed frame 2 can effectively buffer the protective door to prevent the protective door or the fixed frame 2 from being deformed due to the excessive impact force generated by the collision between the protective door and the fixed frame 2, thereby affecting subsequent use. After the protective door is closed, the fixed groove 5 fits on one end of the protective door to prevent the protective door from vibrating.
