[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.
[0020] As Figure 1-5 shown, a shielding door base insulation structure includes a support seat 7. A partition 5 is arranged on the upper part of the support seat 7. The upper part of the partition 5 is connected with support plates 3 on the left and right sides through an insulation mechanism 4. A column 2 is arranged on the upper part of the support plate 3. An anti - detachment mechanism 6 is arranged on the outer periphery of the insulation mechanism 4, and the anti - detachment mechanism 6 is connected with the partition 5.
[0021] In this embodiment, the insulation mechanism 4 includes two upper and lower insulation components 401, two upper and lower spring gaskets 403 and two threaded nuts 404 for each of the upper and lower parts. The lower part of the insulation component 401 is arranged on the upper parts of the left and right sides of the partition 5, and the upper part of the insulation component 401 is arranged on the lower parts of the left and right sides of the support plate 3. The middle parts of the spring gaskets 403 are arranged on the upper and lower sides of the insulation component 401. The upper spring gasket 403 is arranged on the upper part of the support plate 3, and the lower spring gasket 403 is arranged on the lower part of the partition 5. The middle parts of the two threaded nuts 404 are thread - connected to the upper and lower sides of the insulation component 401, and the threaded nuts 404 are arranged on the side away from the spring gaskets 403. A round gasket 402 is arranged on the side of the spring gasket 403 away from the threaded nut 404. The round gasket 402 is sleeved on the upper and lower sides of the insulation component 401. The upper round gasket 402 is arranged on the upper part of the support plate 3, and the lower round gasket 402 is arranged on the lower part of the support seat 7. The support plate 3 is in a "J" shape.
[0022] Specifically, the insulation component 401 is padded between the partition 5 and the support plate 3, and then a round gasket 402, a spring gasket 403 and a threaded nut 404 are sequentially sleeved on the outer periphery of the threaded rod 4011, so as to firmly fix the insulation component 401 between the support plate 3 and the support seat 7. The support plate 3 and the support seat 7 are separated by the insulation isolation seat 4013 and the insulation isolation rubber 4014, effectively achieving insulation. When replacing the insulation component 401, a pad is inserted between the support plate 3 and the support seat 7 to temporarily support the support plate 3, and then the threaded nut 404 is unscrewed, and the replacement can be carried out, which is convenient to operate.
[0023] In this embodiment, the insulating component 401 includes a threaded rod 4011, a fixed plate 4012, an insulating isolation seat 4013 and an insulating isolation rubber 4014. The fixed plate 4012 is arranged on the upper and lower sides of the fixed plate 4012. One end of the threaded rod 4011 is fixedly connected to the side of the fixed plate 4012 away from the insulating isolation seat 4013. The insulating isolation rubber 4014 is arranged on the outer periphery of the threaded rod 4011, the fixed plate 4012 and the insulating isolation seat 4013. The threaded rod 4011 penetrates the insulating isolation rubber 4014. The anti-slip mechanism 6 includes a connecting seat 601, a nut 602, a lead screw 603 and a hook 604. The middle part of the hook 604 is fixedly connected to one end of the lead screw 603, and the other end of the lead screw 603 penetrates the connecting seat 601 and is threadedly connected to the middle part of the nut 602. The nut 602 is arranged on the side of the connecting seat 601 away from the lead hook 604. The left and right sides of the lead hook 604 are arranged on the outer periphery of the insulating component 401, and the support seat 7 is installed on the upper front side of the platform 1.
[0024] Specifically, the left and right sides of the hook 604 are hooked on the outer periphery of the insulating component 401, and then the screw 603 is passed through the connecting seat 601, and the nut 602 is tightened. The hook 604 is tightened by the nut 602, so that the insulating component 401 is biased to the front side to prevent the vibration generated during the operation of the subway from causing the insulating component 401 to slide to both sides.
[0025] Working principle:
[0026] The insulating component 401 is padded between the partition 5 and the support plate 3, and then a circular gasket 402, a spring gasket 403 and a threaded cap 404 are sequentially sleeved on the outer periphery of the threaded rod 4011, so that the insulating component 401 is firmly fixed between the support plate 3 and the support seat 7, and the support plate 3 and the support seat 7 are separated by the insulating isolation seat 4013 and the insulating isolation rubber 4014, so as to effectively achieve insulation. When replacing the insulating component 401, a pad is inserted between the support plate 3 and the support seat 7 to temporarily support the support plate 3, and then the threaded cap 404 is unscrewed to replace it. The operation is convenient. The left and right sides of the hook 604 are hooked on the outer periphery of the insulating component 401, and then the lead screw 603 is passed through the connecting seat 601, and the nut 602 is tightened. The hook 604 is tightened by the nut 602, so that the insulating component 401 is biased to the front side to prevent the vibration generated during the operation of the subway from causing the insulating component 401 to slide to both sides.
