[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] like Figure 1-Figure 3 As shown together, a middle groove for a skylight is provided, comprising: a middle plate 1, the middle plate 1 is provided with a skylight 2, the skylight 2 is provided with a movable plate 3 adapted thereto, the first and second opposite sides of the skylight 2 are respectively provided with middle plate supporting steps 11 for supporting the movable plate 3, a locking structure is provided between the third side opposite to the skylight 2 and the movable plate 3, a limiting structure is provided between the fourth side of the skylight 2 and the movable plate 3, and the third side of the skylight 2 is opposite to the fourth side of the skylight 2.

[0036] The gap between the movable panel 3 and the sunroof 2 is small, limiting the horizontal movement of the movable panel 3. The middle plate support step 11 is used to support the weight of the movable panel 3 and prevent the movable panel 3 from moving downward. The closed locking structure and the limit structure cooperate to locate the vertical position of the movable panel 3, preventing the movable panel 3 from moving upward, thereby stably installing the movable panel 3 in the sunroof 2. The sunroof 2 can be opened by opening the locking structure and removing the movable panel 3 upward, making it easy to open the sunroof.

[0037] like Figure 4-Figure 8 As shown together, the locking structure includes a tongue 4 and a locking member 5. The tongue 4 is provided with a vertical tongue locking member hole 41. The movable plate 3 is provided with a horizontal tongue hole 31 and a vertical movable plate locking member hole 32. The tongue 4 can move horizontally in the tongue hole 31. The tongue locking member hole 41 and the movable plate locking member hole 32 are positioned correspondingly.

[0038] A tongue-limiting step 12 is provided on the third side of the skylight 2;

[0039] The movable plate 3 is provided with a tongue-pushing hole 33 communicating with the tongue-inserting hole 31;

[0040] like Figure 5 As shown, when the locking structure is closed, the tongue 4 is located below the tongue limiting step 12, and the locking member 5 is located in the tongue locking member hole 41 and the movable plate locking member hole 32. The locking member 5 is used to prevent the tongue 4 from escaping from the tongue hole 31, and the tongue 4 is used to prevent the movable plate 3 from moving upward. Figure 6 As shown, when the locking structure is opened, the locking piece 5 is removed and the tongue 4 is pushed toward the tongue hole 33 so that the tongue 4 moves out from under the tongue limiting step 12. Then, the movable panel 3 is in a free state. The movable panel 3 can be taken out of the sunroof 2 by moving the movable panel 3 upward, and the sunroof 2 is opened.

[0041] To facilitate the movement of the tongue 4, a tongue slot 42 is provided at one end of the tongue 4 extending into the tongue hole 33. Furthermore, tongue slots 42 are provided on the upper and lower sides of the tongue 4. The tongue 4 has no front and back positions, making operation convenient.

[0042] The locking member 5 is preferably a resilient cylindrical pin secured in the tongue locking member hole 41 by an interference fit. The movable plate locking member hole 32 has a larger diameter than the resilient cylindrical pin to facilitate removal. The locking member 5 may also be a T-pin or a bolt threadedly connected to the tongue locking member hole 41.

[0043] The inserting tongue can be in the shape of a plate, a rod or a pin.

[0044] In order to more stably install the movable panel 3 in the skylight 2 , in the illustrated embodiment, two sets of locking structures are provided.

[0045] like Figure 10 and Figure 11As shown together, in the illustrated embodiment, the movable plate 3 is provided with a movable plate support step 34 adapted to the middle plate support step 11, and the cooperation of the two step surfaces supports the movable plate 3. In other embodiments, the movable plate 3 can also be directly supported on the middle plate support step 11.

[0046] like Figure 9 As shown, the limiting structure includes a middle plate limiting step 13 provided on the fourth side of the skylight 2 and a movable plate limiting step 35 provided on the movable plate 3 , and the middle plate limiting step 13 and the movable plate limiting step 35 are adapted to each other.

[0047] In order to facilitate the disassembly and assembly of the movable plate 3 , a lifting hole 36 is provided on the movable plate 3 .

[0048] It is difficult to operate lifting equipment in the tunnel, and a brazing groove 37 is provided on the movable plate 3. A brazing tool is inserted into the brazing groove 37 to lift the movable plate 3.

[0049] In the illustrated embodiment, the first side and the second side of the skylight 2 are arranged opposite to each other along the conveying direction of the coal, and the third side and the fourth side of the skylight are arranged opposite to each other in a direction perpendicular to the conveying direction of the coal.

[0050] The above are examples of the best embodiments of the present invention. Any parts not described in detail are common knowledge of those skilled in the art. The scope of protection of the present invention is based on the content of the claims. Any equivalent transformation based on the technical teachings of the present invention is also within the scope of protection of the present invention.
