[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A combined shock-absorbing pad for elevator car body includes an upper buffer assembly 1, a lower buffer assembly 2 arranged parallel below the upper buffer assembly 1, an I-shaped rubber pad 4 detachably connected between the lower buffer assembly 2 and the upper buffer assembly 1, and a limit assembly 3 internally connected between the lower buffer assembly 2 and the upper buffer assembly 1.

[0028] The upper buffer assembly 1 includes an upper buffer silicone rubber pad 101;

[0029] The lower buffer assembly 2 includes a lower buffer silicone rubber pad 201. The lower buffer silicone rubber pad 201 and the upper buffer silicone rubber pad 101 have mounting grooves 5 that are adapted to the I-shaped rubber pad 4 on the side facing the I-shaped rubber pad 4.

[0030] The upper buffer assembly 1 also includes an upper steel plate 102 embedded inside the upper buffer silicone rubber pad 101. A guide sleeve 103 is welded to the side of the upper steel plate 102 facing the I-shaped rubber pad 4. The lower buffer assembly 2 also includes a lower steel plate 202 embedded inside the lower buffer silicone rubber pad 201. A guide rod 203 is welded to the side of the lower steel plate 202 facing the I-shaped rubber pad 4. The guide sleeve 103 is sleeved on the outside of the guide rod 203, and the guide rod 203 and the guide sleeve 103 are in clearance fit. Limiting holes 6 are opened on the left and right sides of the I-shaped rubber pad 4. The limiting hole 6 on the upper side of the I-shaped rubber pad 4 is in clearance fit with the outer diameter of the guide sleeve 103, and the limiting hole 6 on the upper side of the I-shaped rubber pad 4 is in clearance fit with the outer diameter of the guide rod 203.

[0031] By adopting the above technical solution, the upper buffer assembly 1 and the lower buffer assembly 2 are arranged opposite to each other, with their mounting grooves 5 located on the inner side. I-shaped rubber pads 4 are installed inside the mounting grooves 5. Upper steel plates 102 and 202 are respectively embedded inside the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201, improving the rigidity of the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201. Simultaneously, the I-shaped rubber pads 4 arranged in an array between the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201 further improve the buffering performance of the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201. When the lower buffer silicone rubber pad 201 is compressed, the guide sleeve 103 can slide on the surface of the guide rod 203. It expands and contracts as the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201 are compressed, preventing the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201 from deflecting when under force. Since the I-shaped rubber pad 4 is detachably connected to the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201, it is convenient to replace the internal I-shaped rubber pad 4. The entire shock-absorbing pad consists of the upper buffer assembly 1, the lower buffer assembly 2 and the I-shaped rubber pad 4, which form a multi-stage buffer and can be replaced independently, saving replacement costs.

[0032] Specifically, such as Figure 4 As shown, the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201 have fixing holes 7 on the side away from the I-shaped rubber pad 4. The limiting component 3 is installed inside the fixing hole 7. The limiting component 3 includes a limiting screw 302 that penetrates the interior of the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201, and two sets of limiting nuts 301 that are threaded to the end of the limiting screw 302. The limiting screw 302 is located at the four corners and the center of the shock-absorbing pad. The number of limiting screws 302 is adjusted according to the actual area of ​​the shock-absorbing pad to ensure a stable connection between the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201.

[0033] By adopting the above technical solution, after the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201 are installed, the limiting screw 302 passes through the fixing hole 7, and the corresponding positions of the upper steel plate 102 and the lower steel plate 202 are also opened with fixing holes 7. The limiting screw 302 and the limiting nut 301 cooperate with each other to limit the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201. The limiting screw 302 passes through the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201. After the nut is tightened, a gap is reserved to allow a small range of displacement, ensuring the stability of the overall structure and preventing excessive displacement or misalignment. The reserved gap is ±1-2mm.

[0034] Working principle: The upper buffer assembly 1 and the lower buffer assembly 2 are arranged opposite each other, with their mounting grooves 5 located on the inner side. I-shaped rubber pads 4 are installed inside the mounting grooves 5. Upper steel plates 102 and 202 are embedded inside the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201, respectively, to improve the rigidity of the upper and lower buffer silicone rubber pads 101 and 201. Simultaneously, the I-shaped rubber pads 4, arranged in an array between the upper and lower buffer silicone rubber pads 101 and 201, further enhance the cushioning performance of the upper and lower buffer silicone rubber pads 101 and 201. When compressed, the guide sleeve 103 can slide on the surface of the guide rod 203, and expand and contract as the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201 are compressed, so as to prevent the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201 from deflecting when subjected to force. At the same time, after the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201 are installed, the limiting screw 302 passes through the fixing hole 7, and the corresponding positions of the upper steel plate 102 and the lower steel plate 202 are also provided with fixing holes 7. The limiting screw 302 and the limiting nut 301 cooperate with each other to further limit the upper buffer silicone rubber pad 101 and the lower buffer silicone rubber pad 201.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
