[0021] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As shown in Figures 1-4 , an insulating structure for a threshold bracket of a rail transit platform door includes a threshold 1. A plurality of slots 11 arranged in a linear array are formed in the threshold 1. An insulating pad 13 is arranged on the threshold 1. A plurality of plug rods 14 arranged in a linear array are arranged on the insulating pad 13. The plug rods 14 are inserted into the slots 11. Contact bumps 15 are symmetrically arranged on the plug rods 14. A placing groove 12 is formed in the threshold 1. A plurality of fixed components 100 arranged in a linear array are arranged in the placing groove 12. The fixed component 100 includes a connecting plate 30 rotatably and symmetrically arranged in the placing groove 12. The connecting plate 30 is pushed by the plug rod 14 so that a plug plate 32 slidably arranged in the placing groove 12 is inserted into the plug rod 14.

[0023] Specifically, during use, the threshold 1 is installed on the platform, and then the insulating pad 13 is placed on the threshold 1. The plug rods 14 on the insulating pad 13 are inserted into the slots 11. Then, the contact bumps 15 at both ends of the plug rod 14 will contact the fixed component 100 in the placing groove 12. The connecting plate 30 in the fixed component 100 is pushed by the contact bump 15, causing the connecting plate 30 to swing to both sides and the plug plate 32 to be inserted into the plug rod 14, thereby fixing the insulating pad 13 on the threshold 1 to complete the fixation.

[0024] In the above solution, the insulating pad 13 on the threshold 1 is fixed by the slots 11 on the threshold 1. After the plug rods 14 on the insulating pad 13 cooperate with the slots 11, the insulating pad 13 is fixed in the slots 11. The contact bumps 15 on the plug rods 14 contact the connecting plate 30 in the fixed component 100. After contacting the connecting plate 30, the plug plate 32 is pushed into the plug rod 14, and the insulating pad 13 is fixed on the threshold 1 to complete the fixation.

[0025] As a further embodiment provided by the present utility model, according to Figure 2 , Figure 3 and Figure 4As shown, swing plates 25 are symmetrically arranged in the placement groove 12. A first shaft rod 26 is rotationally arranged on the swing plates 25, and a guiding groove 261 is formed in the swing plates 25.

[0026] Further, a sliding plate 281 is slidably arranged in the guiding groove 261. First plate members 28 are symmetrically arranged in the placement groove 12. A predetermined gap is left between the two first plate members 28 to form a first guiding and sliding portion 29, and the sliding plate 281 slides in the first guiding and sliding portion 29.

[0027] Even further, second plate members 33 are symmetrically arranged in the placement groove 12. A predetermined gap is left between the two second plate members 33 to form a second guiding and sliding portion 34, and a plug plate 32 is slidably arranged in the second guiding and sliding portion 34.

[0028] Even further, it includes a connecting plate 30, and the plug plate 32 is rotationally arranged on the connecting plate 30.

[0029] Even further, it includes a plug rod 14. Fixing grooves 23 are symmetrically formed on the plug rod 14, and the connecting plate 30 is inserted into the fixing grooves 23.

[0030] Specifically, when the plug rod 14 moves downward and the contact bump 15 moves downward, it will contact the swing plate 25, causing the swing plate 25 to be pushed against both sides, and causing the guiding groove 261 to move outward synchronously. At the same time, the sliding plate 281 in the guiding groove 261 moves to both sides, and the sliding plate 281 slides outward in the first guiding and sliding portion 29 formed by the first plate members 28 in the placement groove 12, and pushes the connecting plate 30 to swing. The other end of the connecting plate 30 moves in the opposite direction and pushes the plug plate 32 to slide in the second guiding and sliding portion 34 and be inserted into the fixing grooves 23 on the plug rod 14 to fix the insulating pad 13 in the threshold 1.

[0031] As a further embodiment provided by the present utility model, according to Figure 2 As shown, a sliding groove 22 is formed on the plug rod 14, and a sliding rod 16 is slidably arranged in the sliding groove 22.

[0032] Specifically, pushing the sliding rod 16 inward in the sliding groove 22 increases the air pressure in the sliding groove 22, causing the contact bump 15 to expand and push against the swing plate 25.

[0033] Working principle: When in use, install the threshold 1 on the platform, then place the insulating pad 13 on the threshold 1, insert the insertion rod 14 on the insulating pad 13 into the slot 11. When the insertion rod 14 moves downward and the contact bump 15 moves downward, it will contact the swing plate 25, causing the swing plate 25 to be pushed against both sides and the guide groove 261 to move outward synchronously. At the same time, the sliding plate 281 in the guide groove 261 moves to both sides, and the sliding plate 281 slides outward in the first guide sliding part 29 formed by the first plate member 28 in the placement groove 12 and pushes the connecting plate 30 to swing. The other end of the connecting plate 30 moves in the opposite direction and pushes the insertion plate 32 to slide in the second guide sliding part 34 and be inserted into the fixing groove 23 on the insertion rod 14, fixing the insulating pad 13 in the threshold 1 to complete the fixation.

[0034] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
