Secondly, the disassembly and reconnection of some connection methods are relatively difficult and may cause damage to the connection components. In addition, the existing metal mesh frame connection mechanism lacks effective self-restoring force support during docking, which may lead to loose connection after long-term use and affect the use effect. Therefore, the prior art needs to be improved to provide a more efficient, stable and convenient metal mesh frame connection solution. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.
[0020] Embodiment
[0021] Please refer to Figures 1-5, a double-layer grid metal net for mining, including an upper metal net frame 1. A lower metal net frame 2 is arranged at the lower end of the upper metal net frame 1. A connecting mechanism is arranged between the upper metal net frame 1 and the lower metal net frame 2. The connecting mechanism includes an installation groove 31. The size and shape design of the installation groove 31 can ensure that other components of the connecting mechanism can be accurately installed and work. The installation groove 31 is opened at the upper end of the lower metal net frame 2. A connecting shaft 32 is fixedly connected to the bottom of the upper metal net frame 1. A connecting block 33 is fixedly connected to the bottom of the connecting shaft 32. Moving cavities 34 are opened on both sides of the installation groove 31. Through holes are opened on the inner wall of the moving cavities 34. A moving rod 35 is slidably connected inside the through holes. One end of the moving rod 35 located inside the installation groove 31 is fixedly connected with a stop block 36.
[0022] An activity block 37 is fixedly sleeved on the outer wall of the moving rod 35. A tension spring 38 is movably sleeved on the outer wall of the moving rod 35. Two ends of the tension spring 38 are respectively fixedly connected with the moving cavity 34 and the activity block 37. Its function is to provide a restoring force for the connecting mechanism.
[0023] The activity block 37 is slidably connected inside the moving cavity 34.
[0024] A sliding groove 39 is opened on the outer wall of the lower metal net frame 2. One end of the moving rod 35 far away from the stop block 36 is fixedly connected with a moving block 310. The moving block 310 is slidably connected to the outer wall of the sliding groove 39.
[0025] One side of the stop block 36 far away from the moving rod 35 is set as an inclined surface. Two sides of the connecting block 33 are set as inclined surfaces.
[0026] A guiding shaft 41 is fixedly connected to the upper end of the lower metal net frame 2. A guiding hole 42 is opened inside the upper metal net frame 1. Its function is to help accurately position the upper metal net frame 1 and the lower metal net frame 2 during docking, ensure their docking accuracy and firmness, and thus facilitate the smooth splicing between the metal net frames.
[0027] During use, when it is necessary to splice the upper metal net frame 1 and the lower metal net frame 2, align the guiding hole 42 of the upper metal net frame 1 with the guiding shaft 41. Then, the connecting shaft 32 and the connecting block 33 at the bottom of the upper metal net frame 1 will enter the inside of the installation groove 31. Furthermore, the connecting block 33 will contact the stop block 36. Thus, the connecting block 33 will push the stop block 36 to move to both sides. When the connecting block 33 moves to the lower end of the stop block 36, at this time, the tension spring 38 will drive the activity block 37 to slide inside the moving cavity 34 by pulling, and then will drive the moving rod 35 to move inwards. Furthermore, the stop block 36 will limit the upper end of the connecting block 33. Thus, the fixed connection between the upper metal net frame 1 and the lower metal net frame 2 is realized.
[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
