[0039] As Figure 1-2 shown, an embodiment of the present utility model provides a waterproof device for a lifting device passing through a cabin, including a fixed cover 10, a lifting rod 20, a top cover 30, and a wire reel 40. Among them, the fixed cover 10 is installed on the top 60 of the vehicle cabin and is used to cover the cabin opening 70; the bottom of the lifting rod 20 is installed inside the vehicle cabin 80, and the top end passes through the fixed cover 10. It should be understood that the specific structural shape of the lifting rod 20 can be designed according to actual needs and is not limited in the description of this embodiment. For example, it can be a square rod or a round rod; the top cover 30 is installed at the top end of the lifting rod 20; the wire reel 40 is installed on the top of the fixed cover 10 and is located below the top cover 30 and is used to store the spiral cable. At the same time, the wire reel 40 is formed with a water collection area 41 and a water outlet 42 communicating with it to collect rainwater through the water collection area 41 and discharge it outside the top 60 of the vehicle cabin through the water outlet 42.

[0040] In the embodiment of the present utility model, by setting the fixed cover 10, the lifting rod 20, the top cover 30, and the wire reel 40, when the lifting rod 20 is unfolded, the top cover 30 rises with the lifting rod 20. At this time, rainwater enters the water collection area 41 of the wire reel 40 and is discharged outside the top 60 of the vehicle cabin through the water outlet 42, effectively preventing rainwater from directly flowing into the vehicle cabin 80 from the cabin opening 70; when the lifting rod 20 is closed, the top cover 30 covers the wire reel 40 to block rainwater from entering the water collection area 41 of the wire reel 40.

[0041] Specifically, as Figure 2As shown, in the embodiment of the present utility model, the wire take-up cylinder 40 includes a cylinder body 43 with an open upper end and a closed lower end. The cylinder body 43 includes an inner ring 431 and an outer ring 432. The inner ring 431 contacts the inner surface of the sleeve 21 of the lifting rod 20, so that the lifting rod 20 can move smoothly and smoothly during the telescopic action, and at the same time, it can also prevent moisture from flowing into the vehicle along the lifting rod 20. A water collection area 41 for storing rainwater entering from the top is formed between the inner ring 431 and the outer ring 432. The water outlet 42 is provided on the side wall of the outer ring 432. Multiple water outlets 42 can be provided, which can accelerate the drainage speed of the accumulated water in the water collection area 41. At the same time, if one water outlet 42 is blocked by sundries such as leaves and dust, the other water outlets 42 can still work normally to ensure normal drainage operation.

[0042] Specifically, as Figure 3 shown, in the embodiment of the present utility model, the inner ring 431 and the outer ring 432 are both formed with stepped steps 433. Each stepped step 433 can be used as a small water collection area 41 region, which helps to disperse the water flow and reduce the risk of excessive water accumulation in a single area. The gap between the stepped steps 433 can be used as an additional drainage path to further improve the drainage efficiency.

[0043] Specifically, as Figure 2 shown, in the embodiment of the present utility model, the fixed cover 10 is fixed on the welding frame of the vehicle cabin roof 60 through fasteners, so that the fixed cover 10 is firmly installed on the roof and is convenient for maintenance and replacement.

[0044] Specifically, as Figure 4 shown, in the embodiment of the present utility model, the center of the fixed cover 10 has a through hole, and the top end of the lifting rod 20 passes through the through hole to facilitate the up and down movement of the lifting rod 20 in the fixed cover 10, thereby driving the top cover 30 to rise or fall.

[0045] Specifically, as Figure 5 shown, in the embodiment of the present utility model, the two ends of the top cover 30 are bent downward to form corners 31. The wire take-up cylinder 40 is located between the two corners 31. The downwardly bent corners 31 help to guide the rainwater along the edge of the top cover 30 to flow out of the vehicle, prevent the accumulated water from entering the interior of the carriage, and at the same time cover the wire take-up cylinder 40 to block the rainwater from entering the water collection area 41 of the wire take-up cylinder 40.

[0046] Based on the above scheme, as Figure 6As shown, in the embodiment of the present utility model, it further includes a fixture 50 for fixing the lifting rod 20, and the fixture 50 is installed on the top of the fixed cover 10; specifically, the fixture 50 includes two clamping plates 51, each clamping plate 51 includes two fastening parts 511, through holes are provided on both of the two fastening parts 511, and the two clamping plates 51 are fixed by bolts 512 through the two opposite fastening parts 511, and the bolts 512 pass through the through holes corresponding to the fastening parts 511.

[0047] During use, place the two clamping plates 51 on both sides of the lifting rod 20 respectively, make their fastening parts 511 face each other, ensure the correct position of the clamping plates 51, and be able to evenly surround the lifting rod 20. Then pass the bolt 512 through the through hole on the fastening part 511 of one clamping plate 51, and then through the through hole on the corresponding fastening part 511 of the other clamping plate 51. Subsequently, add a washer and a nut to the other end of the bolt 512, and gradually tighten the nut using a wrench or a torque wrench until the clamping plates 51 firmly clamp the lifting rod 20. And during the fastening process, attention should be paid to applying force evenly to ensure that the two clamping plates 51 are evenly stressed and avoid one side being too tight and the other side being loose.

[0048] Specifically, as Figure 6 shown, in the embodiment of the present utility model, the clamping surfaces of the two clamping plates 51 are adapted to the outer surface of the lifting rod 20 to ensure that the clamping plates 51 closely fit the lifting rod 20 and provide a better fixing effect. For example, if the lifting rod 20 is circular, the inner side of the clamping plate 51 should be semi-circular; if it is square or other shapes, the inner side of the clamping plate 51 should be made into the corresponding shapes accordingly. At the same time, in order to better fit the lifting rod 20, the inner side of the clamping plate 51 can have a little elasticity or use a material with a certain elasticity (such as spring steel) to adapt to slight dimensional changes.

[0049] It should be noted that in this application document, the specific connection methods of each component all adopt the conventional means of mature bolts in the prior art for connection, and the machinery, parts and equipment all adopt the conventional models in the prior art. Therefore, no specific description will be made here.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
