[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0027] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0028] Please refer to Figure 1-Figure 4 The utility model provides a longitudinal fast rebound damper, which includes an automatic rolling curtain shaft 1 arranged at the top, a windshield cloth 2 arranged at the lower part of the automatic rolling curtain shaft 1, a windshield plate 6 arranged at the lower part of the windshield cloth 2, two sliders arranged on both sides of the windshield plate 6, slots 4 arranged on both sides of the windshield plate 6 for sliding of the sliders, and a rotating block 7 arranged at the lower end of the slot 4.

[0029] See also Figure 1 The windshield 2 is provided with uniformly arranged steel keels 3. The axial direction of the steel keels 3 is parallel to the long side direction of the automatic rolling curtain shaft 1. Such a configuration can enhance the rigidity and stability of the windshield 2, improve its wind pressure resistance, and extend its service life.

[0030] Please refer to Figure 1 and Figure 2 The slider is a rectangular parallelepiped. The slider is fixedly connected to the windshield 6. The height of the slider is equal to the height of the windshield 6, and the thickness of the slider is greater than the thickness of the windshield 6. The slider slides in the slot 4. This arrangement can ensure the stability of the slider during the sliding process, while preventing the windshield 6 from being bent or deformed due to the wind flow.

[0031] The upper and lower ends of the two sliders are both provided with handles 5. The handles 5 are clamped by the rotating clamping block 7. Such a configuration can facilitate the user to hold and operate the handles 5 from different heights, realize the rapid opening and closing of the damper, and ensure that the damper can be firmly locked when closed.

[0032] The rotating block 7 is configured to be L-shaped, the long end of the rotating block 7 is fixedly connected to the card slot 4, the short end of the rotating block 7 is configured to be arc-shaped, and the outer edge of the short end of the rotating block 7 is provided with gear teeth. Such a configuration can provide a reliable locking mechanism, making the rotating block 7 easy to grasp and rotate during operation, while the gear design increases the friction with the sole, making it convenient for the user to rotate the block 7 with his foot to clamp or release the handle 5.

[0033] The card slot 4 is concave. The upper end of the card slot 4 is fixedly connected to the automatic rolling curtain shaft 1. This arrangement can ensure that the slider slides smoothly in the concave card slot 4, and the fixed connection between the upper end and the automatic rolling curtain shaft 1 enhances the stability of the overall structure, making the damper more firm and durable during operation.

[0034] The working principle of the present invention is further described below in conjunction with specific embodiments:

[0035] A longitudinal fast-rebound damper is installed in a specific area of ​​the mine. The damper consists of an automatic rolling curtain shaft 1, a wind shield cloth 2, a wind shield plate 6, a slider, a slot 4, and a rotating block 7.

[0036] Closing the damper: When the damper needs to be closed, the operator first holds the handle 5 at the upper end of the slider, and pulls the windshield 6 and the windshield cloth 2 downward to the predetermined position. At this time, the slider slides smoothly in the concave slot 4. When the windshield 6 drops to the lowest point, the operator applies pressure to the rotating block 7 with his feet, and the rotating block 7 rotates. At this time, the rotating block 7 clamps the handle 5 to ensure that the damper is in the closed state. The long end of the rotating block 7 is fixedly connected to the slot 4 to ensure the stability of the damper when it is closed.

[0037] Opening the damper: When the damper needs to be opened, the operator only needs to gently push the rotating block 7 with his foot until the long side of the rotating block 7 is in a horizontal position, so that the handle 5 is released. When the rotating block 7 is pushed open, the energy stored in the spring in the automatic rolling curtain shaft 1 is released, driving the windshield 2 to be quickly retracted, so as to realize the rapid opening of the damper. The steel keel 3 on the windshield 2 helps the windshield 2 to maintain its shape and improve its wind pressure resistance, ensuring the stability of the damper under the action of wind flow.

[0038] In summary, the utility model provides a longitudinal fast rebound damper, which realizes the rapid opening and closing of the damper by setting the automatic rolling curtain shaft 1 and the wind shield cloth 2, and improves the response speed of the wind flow control. The design of the wind shield plate 6 and the slider, the card slot 4 and the rotating block 7 greatly simplifies the structure of the damper, facilitates installation and maintenance, and reduces the production cost and maintenance difficulty. This design significantly improves the rebound performance of the damper under the action of wind flow, ensuring the efficiency and stability of the damper opening and closing process.
