However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0020] Embodiment 1:

[0021] Such as Figures 1 - 3As shown in the figure, a steel waterproof rolling shutter with good bottom sealing effect includes a rolling gate body 1 and a sealing mechanism. The sealing mechanism includes a sealing bottom pad body 2 and two sealing bottom pad side bodies 3. The sealing bottom pad body 2 and the two sealing bottom pad side bodies 3 are both located at the bottom end face of the rolling gate body 1. Soft rubber plates 21 are provided at the tops of the sealing bottom pad body 2 and the sealing bottom pad side bodies 3. A connecting slot 11 is opened on the bottom end face of the rolling gate body 1. One end of the soft rubber plate 21 is inserted into the inner side of the connecting slot 11. A penetrating slot 22 is opened inside the soft rubber plate 21. First threaded grooves 12 communicating with the connecting slot 11 are opened on both the front and back sides of the rolling gate body 1. A positioning screw 13 is threadedly connected inside the first threaded groove 12. The middle end of the positioning screw 13 penetrates through the penetrating slot 22. A connecting component is provided between the sealing bottom pad body 2 and the sealing bottom pad side bodies 3; The connecting component includes an outer slot 23 and an internal threaded groove 24. The outer slot 23 is opened on the outer side of the sealing bottom pad body 2. The internal threaded groove 24 is opened on the inner side of the outer slot 23. A third threaded groove 31 is opened on the end face of one end of the sealing bottom pad side body 3 close to the sealing bottom pad body 2. A connecting screw 25 is threadedly connected between the internal threaded groove 24 and the third threaded groove 31. One end of the connecting screw 25 extends into the inner side of the outer slot 23 and is fixedly connected with an auxiliary rotating block 26. A part of the auxiliary rotating block 26 is located outside the sealing bottom pad body 2;

[0022] A rolling shutter is a door with multiple jointed door panels connected in series. In a fixed slideway, it rotates up and down with the reel above the door as the center. It consists of multiple parts such as curtain boards, seat boards, guide rails, supports, reels, boxes, control boxes, rolling door machines, limiters, door lintels, manual quick-release switch devices, button switches, and safety devices. It is generally installed in areas where it is inconvenient to use wall partitions;

[0023] Most rolling shutters are made of steel. When fully lowered, there will be more or less gaps between them and the ground. In special situations such as rainy days, water is likely to enter, which is not conducive to moisture-proof management in the room;

[0024] First, insert the soft rubber plate 21 from below into the connecting slot 11, and then align the positioning screw 13 with the first threaded groove 12 and rotate it to connect with the first threaded groove 12 and penetrate through the penetrating slot 22 at the same time, then the sealing bottom pad body 2 can be installed on the rolling gate body 1. Then, install the two sealing bottom pad side bodies 3 in the same way. Then, put the combination of the connecting screw 25 and the auxiliary rotating block 26 into the outer slot 23, align the connecting screw 25 with the internal threaded groove 24, and then rotate the auxiliary rotating block 26. The auxiliary rotating block 26 pushes the connecting screw 25 into the third threaded groove 31 to connect the sealing bottom pad body 2 and the sealing bottom pad side bodies 3, so that the combination of the sealing bottom pad body 2 and the sealing bottom pad side bodies 3 can replace the rolling gate body 1 to contact the ground and improve the sealing performance;

[0025] The relatively soft sealing gasket main body 2 can be made to contact the ground instead of the rolling shutter main body 1, thereby filling the gap with the ground to prevent liquid from entering. At the same time, there is a relatively tight and easily disassembled and assembled structure among the sealing gasket main body 2, the sealing gasket edge body 3, and the rolling shutter main body 1, which is convenient for replacement or maintenance after the components age.

[0026] In other embodiments, this embodiment discloses, please refer to Figure 2 As shown, at one end outside the back surface of the rolling shutter main body 1, the positioning screw 13 is threadedly connected with a limit nut 14, and anti-rust paint is provided on both the positioning screw 13 and the limit nut 14; through this design, the other end of the positioning screw 13 can be further limited, thereby improving the connection stability between the rolling shutter main body 1 and the sealing gasket main body 2, and the design of the anti-rust paint can extend the service life and prevent rusting.

[0027] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, the length of the soft rubber plate 21 is 0.95 times the length of the sealing gasket main body 2 or the sealing gasket edge body 3, and decorative paint is provided on the outside of both the sealing gasket main body 2 and the sealing gasket edge body 3; through this design, the area of the soft rubber plate 21 is larger, which can better lift the sealing gasket main body 2, and the presence of the decorative paint can improve the aesthetics of the sealing gasket main body 2 and the sealing gasket edge body 3.

[0028] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, the first thread grooves 12 are arranged at equal distances around the top end face of the sealing gasket main body 2 or the sealing gasket edge body 3, and the number of the positioning screws 13 is the same as that of the first thread grooves 12; through this design, the connection stability between the sealing gasket main body 2, the sealing gasket edge body 3 and the rolling shutter main body 1 is improved. Since it takes a long time for the sealing gasket main body 2 and the sealing gasket edge body 3 to age and there is no need to frequently disassemble and assemble them, the arrangement of multiple positioning screws 13 and first thread grooves 12 does not affect the use.

[0029] Embodiment 2:

[0030] In other embodiments, this embodiment discloses, please refer to Figure 1 、 Figure 4 As shown, the sealing gasket main body 2 includes a sealing rubber pad 201, an adhesive 202, a hard material main body 203 and a hard rubber plate 204. The sealing rubber pad 201 is located at the bottommost end, the hard material main body 203 is located at the top of the sealing rubber pad 201, and the adhesive 202 is located at the connection between the sealing rubber pad 201 and the hard material main body 203. The hard rubber plate 204 is located at the top of the hard material main body 203, and a wear-resistant coating is provided at the bottom end of the sealing rubber pad 201;

[0031] The sealing rubber gasket 201 contacts the ground, enhancing the sealing performance and the presence of the wear-resistant layer can improve the service life. The presence of the adhesive 202 enables the replacement of the sealing rubber gasket 201 without disassembling the sealing bottom gasket main body 2 and the sealing bottom gasket side body 3 when the service life expires. The hard material main body 203 provides sufficient strength for the sealing bottom gasket main body 2. The hard rubber plate 204 contacts the rolling shutter main body 1, being soft yet having a certain hardness and not causing wear to the rolling shutter main body 1. Making the composition of the sealing bottom gasket main body 2 or the sealing bottom gasket side body 3 more scientific can provide sufficient sealing performance while having a certain strength.

[0032] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the relevant technical field.
