DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] Embodiment 1

[0023] As Figures 1-5 shown, a kind of elevator anti-collision device with a buffer structure in the illustration includes a fixed bottom plate 1 and a protection mechanism arranged above the fixed bottom plate 1. The protection mechanism includes a buffer assembly and a protection assembly;

[0024] The buffer assembly includes a spring 2, a damper 3 and a guide rod 4. Springs 2 are arranged in an array above the fixed bottom plate 1, a damper 3 is installed inside the spring 2, and guide rods 4 are installed on both the left and right sides of the fixed bottom plate 1;

[0025] The protection assembly includes a pressure-bearing top plate 5, an installation inner cavity 6, a protection airbag 7, a central column 8, a thin groove 9, an igniter 10, a partition plate 11, a top original piece 12 and a cover plate 13. The top of the spring 2 is fixedly installed with a pressure-bearing top plate 5. An installation inner cavity 6 is opened inside the pressure-bearing top plate 5. A protection airbag 7 is fixedly installed on the side of the installation inner cavity 6. A central column 8 is fixedly installed at the central position of the installation inner cavity 6. A thin groove 9 is opened at the bottom side of the central column 8. An igniter 10 is installed inside the central column 8. A partition plate 11 is fixedly installed on the side of the central column 8. Top original pieces 12 are arranged in an array on the top of the pressure-bearing top plate 5, and a cover plate 13 is installed at the position corresponding to the central column 8 on the top of the pressure-bearing top plate 5.

[0026] The springs 2 are distributed in an array above the fixed bottom plate 1. The pressure-bearing top plate 5 and the fixed bottom plate 1 form a pressing structure through the cooperation between the spring 2 and the damper 3. During use, after the pressure-bearing top plate 5 receives an impact force, the impact force will be buffered through the spring 2 and the damper 3 at the bottom, and the impact force will be absorbed, so as to reduce the damage to the elevator and facilitate the device to protect the elevator.

[0027] The pressure-bearing top plate 5 and the fixed bottom plate 1 form a sliding structure through the guide rod 4. The guide rods 4 are symmetrically arranged above the fixed bottom plate 1. During use, when the pressure-bearing top plate 5 moves downward under the impact force, the pressure-bearing top plate 5 will slide along the track of the guide rod 4, avoiding the position of the pressure-bearing top plate 5 in the device from changing when it is impacted, which affects the protection effect of the device.

[0028] Embodiment 2

[0029] As Figures 3-5As shown, this embodiment further elaborates on Embodiment 1. The partition 11 is wrapped inside the protective airbag 7. The bottom of the protective airbag 7 is fixedly connected to the installation cavity 6, and the protective airbag 7 and the installation cavity 6 are sealed from each other. During use, the partition 11 can be filled with and inflated by the gas generated after the fuel inside the installation cavity 6 burns, protecting the elevator at the top and preventing the elevator from being damaged. At the same time, during use, the smooth edge of the partition 11 will not damage the protective airbag 7 and affect the use of the protective airbag 7, improving the safety of the device.

[0030] The partitions 11 are distributed in an array on the side of the central column 8. The edges of the partitions 11 are smooth. During use, the partitions 11 can divide the space inside the installation cavity 6. Fuel can be placed inside the installation cavity 6 and then separated by the partitions 11 to prevent uneven distribution of the fuel inside the device from affecting its use.

[0031] During use: First, after the pressure-bearing top plate 5 is subjected to a major impact, it will buffer the impact force through the springs 2 and dampers 3 at the bottom, absorbing the impact force, thereby reducing the damage to the elevator and facilitating the device to protect the elevator. Then, during the process of the pressure-bearing top plate 5 moving downward under the impact force, the pressure-bearing top plate 5 will slide along the trajectory of the guide rod 4 to prevent the pressure-bearing top plate 5 from changing its position inside the device when it is impacted, which may affect the protective effect of the device. At the same time, the partition 11 can be filled with and inflated by the gas generated after the fuel inside the installation cavity 6 burns, protecting the elevator at the top and preventing the elevator from being damaged. At the same time, during use, the smooth edge of the partition 11 will not damage the protective airbag 7 and affect the use of the protective airbag 7, improving the safety of the device. The partitions 11 can divide the space inside the installation cavity 6. Fuel can be placed inside the installation cavity 6 and then separated by the partitions 11 to prevent uneven distribution of the fuel inside the device from affecting its use.
