[0026] Example:

[0027] Reference Figure 1-5 As shown, this embodiment proposes a steel protective door blocking plate, which is installed at the opening wall 1 of the protective door, including a guide rail 3 and a plurality of sealing plate monomers 2 connected end to end. The sealing plate monomer 2 is provided with a sliding portion 8 to slide with the guide rail 3. The sealing plate monomer 2 is provided with a matching groove 4 and a matching portion 7 at its head and tail ends respectively. The matching groove 4 includes a first groove portion 41 and a second groove portion 42 that are interconnected and perpendicular to each other. The matching portion 7 is suitable for inserting into the matching groove 4 and simultaneously forming a match with the second groove portion 42 and the second groove portion 42. After the match, the matching portion 7 blocks the gap of the matching groove 4 opened by the sealing plate monomer 2, thereby ensuring the sealing after the match. This embodiment is different from the splicing method of the sealing plate in the prior art. Through the match between the first groove portion 41 and the second groove portion 42 and the matching portion 7, on the one hand, such a matching piece has a better limiting effect, and on the other hand, the part that is convenient to connect has a bending setting, and its sealing is better after assembly; when installing, the sealing plate monomers 2 can be inserted in sequence, and the matching portion and the corresponding matching groove will automatically limit the corresponding position, thereby facilitating installation.

[0028] Specific as Figure 1 , Figure 2 As shown, the first groove portion 41 is opened perpendicularly to the front edge of the sealing plate monomer 2, and the second groove portion 42 is arranged on the back of the sealing plate monomer 2. The first groove portion 41 extends from the front of the sealing plate monomer 2 to connect with the second groove portion 42; the corresponding matching portion 7 includes a matching plate starting from the back of the sealing plate monomer 2, and a matching vertical plate extending vertically on the matching plate. The matching plate matches with the first groove portion 41, and the matching vertical plate matches with the second groove portion 42. In fact, the matching plate is Figure 1 , Figure 2 The matching vertical plate is not shown, but the matching plate can actually be referenced Figure 2 The sliding part 8 in the embodiment has similar structures (even can be the same), and the sliding part 8 and the matching plate can be produced at the same time during production, thereby reducing production costs.

[0029] Reference Figure 2 As shown, positioning holes 6 are provided at corresponding positions of the mating plate and the first groove portion 41. When two adjacent sealing plate units 2 are installed, the mating plate of one of them is connected to the first groove portion 41 of the other and the positioning holes 6 of the two are made to correspond. After installation, screws can be screwed into the positioning holes 6 for reinforcement.

[0030] like Figure 1 Figure 4 and Figure 5 As shown, one side of the guide rail 3 is provided with an abutment portion 5, and the other side is an open side, and the side of the multiple sealing plate monomers 2 with the matching grooves 4 is installed and slid in from the open side in sequence until the innermost sealing plate monomer 2 abuts against the abutment portion 5. Two preferred specific embodiments of the abutment portion 5 are proposed below:

[0031] (1) The abutment portion 5 is fixedly mounted on the outer side of the guide rail 3, and the cover plate unit 2 is abutted against the fixed position after being mounted, thereby completing the mounting.

[0032] (2) The abutment portion 5 is slidably disposed within the outer side of the guide rail 3, and an adjustment column 32 is disposed relative to the abutment portion 5, and the adjustment column 32 is suitable for adjusting the distance between the abutment portion 5 and the outermost side of the guide rail 3. Compared with the first embodiment, the abutment portion 5 of this embodiment has a certain degree of adjustability, which is helpful for fitting the sealing plate monomer 2 in actual use, thereby achieving better sealing performance.

[0033] like Figure 5 As shown, the adjusting column 32 is threadedly connected to the outermost side of the guide rail 3. The guide rail 3 includes two upper and lower track spaces 31. Slide blocks 9 are provided on the upper and lower sides of the abutting portion 5. The slide blocks 9 are limited and slide in the track space 31. When the adjusting column 32 rotates, the innermost end thereof moves inside the track space 31 through the action of the thread. The slide block 9 abuts against the innermost side of the adjusting column 32 in the track space 31. After the sealing plate monomer 2 is installed, the adjusting column 32 is adjusted toward the inner side of the track space 31 so that the adjusting column 32 presses the abutting portion 5 tightly against the sealing plate monomer 2. In this embodiment, the abutting portion 5 can be initially set at the position when the slide block 9 abuts against the end of the track space 31. After the sealing plate monomer 2 is installed in sequence, the adjusting column 32 is used to make the abutting portion 5 abut against the sealing plate monomer 2.

[0034] like Figure 5 As shown, the width of the track space 31 within the sliding range of the slider 9 is smaller than the width of the track space in the rest of the range, so that the track space 31 is formed with a step 10 at the end of the range of the slider 9. Before adjusting the adjusting column 32, the adjusting column 32 is located at the outermost position of its adjustable range. When the sealing plate monomers 2 are inserted in sequence, the sliding limit of the sliding portion 8 of the innermost sealing plate monomer 2 is the position where it abuts against the step 10. Therefore, during installation, the sealing plate monomer 2 can be inserted into the guide rail 3 at will, and with the limitation of the sliding portion 8 and the step 10, the installation is simple.

[0035] like Figure 4As shown, the sliding portion 8 is fixed to the reverse side of the sealing plate monomer 2, and a sealed space is formed between the innermost side of the sliding portion 8 and the innermost side of the sealing plate monomer 2. The opening wall 1 is provided with an annular sealing opening within the range of the sealed space. After a plurality of sealing plate monomers 2 are installed in sequence, the reverse side of the whole seals the entire annular sealing opening, thereby effectively increasing the sealing performance.

[0036] The protective door blocking plate also includes an outer sealing plate, which is provided with a matching groove 4, and the outer side of the outer sealing plate is a plane, so that after installation, the outer sealing plate is arranged at the outermost side, and there will be no problem of protrusion of the matching portion 7.

[0037] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
