[0029] Specifically, such as Figure 5 The door slide 22 shown has one end facing away from the sliding support rod 3 as the first end, and the other end as the second end, which can lift the upper end of the door body 2 vertically upward and pull it backward away from one side of the base frame 1, so that the lower end of the door body 2 rises and slides while the upper end flips away from the base frame 1 to expose the inspection channel 11, and at this time the door body 2 is located above the inspection channel 11 and is perpendicular to the base frame 1. At this time, when the first sliding portion 21 of the door body 2 slides to the upper end of the vertical slide groove 14, the second sliding portion 31 of the sliding support rod 3 slides along the door slide groove 22 into the lower groove 221 to flip the door body 2 perpendicular to the base frame 1 close to the inspection channel 11 and then lock it, that is, the door body 2 First, flip and slide to the top of the inspection channel 11 and perpendicular to the base frame 1, and then the second sliding part 31 slides into the lower slide groove 221, so that the door body 2 rotates downward with the first sliding part 21 as the rotation axis close to the inspection channel 11, until the second sliding part 31 hits the end of the lower slide groove 221. At this time, the door body 2 is tilted and located on the upper side of the inspection channel 11, and the sliding support rod 3 acts as a hard locking part to pull and lock the door body 2, further improving the locking stability of the door body 2. Secondly, the tilted door body 2 can also prevent debris from falling and hitting the operator standing at the inspection channel 11, thereby improving maintenance safety.

[0030] As an embodiment further provided by the present invention, a mounting groove 13 is provided on the base frame 1 , and a rotating portion 32 is provided on the sliding support rod 3 , and the rotating portion 32 is rotatably disposed in the mounting groove 13 .

[0031] Specifically, a mounting groove 13 is provided on the base frame 1 , and a rotating portion 32 is provided on the sliding support rod 3 . The rotating portion 32 is rotatably disposed in the mounting groove 13 , and the rotating portion 32 is utilized to improve the rotational stability of the sliding support rod 3 .

When the door body 2 is parallel to the base frame 1 to block the inspection channel 11, the sliding support rod 3 is used to pull the upper end of the door body 2 close to the base frame 1 to block the inspection channel 11. At this time, the protrusions 33 are embedded in a plurality of lower grooves opened in the mounting groove 13, thereby further improving the pulling stability of the sliding support rod 3 on the door body 2 at this time, and improving the shielding stability of the door body 2 on the inspection channel 11.

[0034] As a further embodiment provided by the present invention, an airbag component 5 is provided on the first side of the sliding support rod 3, and the door body 2 is parallel to the base frame 1 to pull the airbag component 5 on the sliding support rod 3 to squeeze the inner wall of the installation groove 13 and deform and shrink.

[0035] Specifically, an airbag component 5 is provided on the first side surface of the sliding strut 3, and the door body 2 is parallel to the base frame 1 to pull the airbag component 5 on the sliding strut 3 to squeeze the inner wall of the installation groove 13 and deform and shrink. That is, when the door body 2 rotates and slides from the upper side of the inspection channel 11 to be parallel to the base frame 1, the sliding strut 3 rotates to make the airbag component 5 rotate and squeeze on the inner wall of the installation groove 13, so that the airbag component 5 plays a buffering role when the door body 2 moves and resets from the open state to the closed state, thereby reducing the impact force when the door body 2 is closed.

[0036] As a further embodiment provided by the present invention, a spray hole 34 and a connecting groove 35 are provided on the sliding support rod 3 . The spray hole 34 faces the vertical sliding groove 14 , and the connecting groove 35 is connected to the airbag component 5 .

Figure 3 As shown, the left end of the arc-shaped spring plate 4 is the first end, and the right end is the second end.

[0040] When the upper end of the door body 2 is lifted vertically upward and pulled back away from one side of the base frame 1, the lower end of the door body 2 rises and slides while the upper end flips away from the base frame 1 to expose the inspection channel 11, and at this time the door body 2 is located above the inspection channel 11 and is perpendicular to the base frame 1. At this time, when the first sliding portion 21 of the door body 2 slides to the upper end of the vertical slide groove 14, the sliding support rod 3 rotates and swings to pressurize the arc-shaped spring plate 4. At this time, the arc-shaped spring plate 4 has a buffering effect on the opening of the door body 2, reducing the impact force when the door body 2 is opened, and the second sliding portion 31 of the sliding support rod 3 slides along the door slide groove 22 into the lower groove 221 to flip the door body 2 perpendicular to the base frame 1. It is locked after approaching the inspection channel 11, that is, the door body 2 first flips and slides to the top of the inspection channel 11 and perpendicular to the base frame 1, and then the second sliding part 31 slides into the lower slide groove 221, so that the door body 2 rotates downward with the first sliding part 21 as the rotation axis, close to the inspection channel 11, until the second sliding part 31 contacts the end of the lower slide groove 221. At this time, the door body 2 is tilted and located on the upper side of the inspection channel 11, and the sliding support rod 3 acts as a hard locking part to pull and lock the door body 2, and the arc-shaped spring plate 4 pushes the sliding support rod 3 to increase the locking force of the sliding support plate 3 on the door body 2 when it is opened, thereby improving the locking stability of the door body 2 when it is opened.

[0041] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
