Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figures 1-7 shown, the present invention provides a technical solution: a galvanized steel plate base for installing a rail transit seat, including a backrest substrate 1;

[0046] Furthermore, the strengthening and fixing structure 4 includes a fixing block 7, a welding block 8 is fixedly connected to the fixing block 7, the fixing block 7 is fixed to the vehicle body of the rail transit vehicle through the welding block 8, and a galvanized steel plate structure 6 is fixedly connected to the side of the fixing block 7 away from the welding block 8. A block mortise and tenon structure 5 is arranged inside the galvanized steel plate structure 6.

[0047] Furthermore, a protective shell 503 is fixedly connected inside the galvanized steel plate structure 6, a hole groove for accommodating the protective shell 503 is formed in the galvanized steel plate structure 6, a fixing column 505 is fixedly connected to the inner side surface of the protective shell 503, a spring 504 slides on the outer wall of the fixing column 505, and the spring 504 is fixedly connected to the protective shell 503. A protruding block 501 is fixedly connected to the upper surface of the fixing column 505, the spring 504 is fixedly connected to the protruding block 501, a hole groove matching the fixing column 505 is formed inside the protruding block 501, the fixing column 505 is located in the hole groove, a movable hole groove 502 is formed in the galvanized steel plate structure 6, the movable hole groove 502 matches the protruding block 501, the protruding block 501 matches the fixing hole 201, and a slot hole matching the galvanized steel plate structure 6 is formed inside the seat base plate 2. The galvanized steel plate structure 6 is fixedly connected to the seat base plate 2 through the protruding block 501.

[0048] The spring 504 is a mechanical part that works using elasticity. Parts made of elastic materials deform under the action of external forces and return to their original state after the external forces are removed. Generally, it is made of spring 504 steel, and the types of springs 504 are complex and diverse.

[0049] By providing a protruding block 501 on the galvanized steel plate structure 6 that can be driven to expand and contract up and down by the spring 504, and by providing a mutually matching slot hole on the seat base plate 2, the protruding block 501 can be clamped at the slot hole for fixation, which is fast, convenient and firm. And by fixing a reinforcing plate layer 602 on the steel core plate 603 and plating a galvanized layer 601 on the outer layer of the reinforcing plate layer 602, the strength of the seat base plate 2 can be effectively enhanced, the situation of rust can be prevented, and the service life of the seat can be greatly improved.

[0050] Further, the galvanized steel plate structure 6 includes a steel core plate 603. A reinforcing plate layer 602 is fixedly connected to the outer side surface of the steel core plate 603. A galvanized layer 601 is fixedly connected to the outer side surface of the reinforcing plate layer 602. The galvanized layer 601 is fixedly connected to the fixing block 7.

[0051] Further, the support frame 3 includes a steel frame 304. A plurality of reinforcing ribs 305 are fixedly connected to the inner side surface of the steel frame 304. A fixing mounting plate 303 is fixedly connected to the upper surface of the steel frame 304. A fixing block 301 is fixedly connected to the upper surface of the fixing mounting plate 303. A plurality of fixing threaded holes 302 are formed in the fixing mounting plate 303. The steel frame 304 is fixedly connected to the seat base plate 2 and the strengthening and fixing structure 4 through the fixing mounting plate 303.

[0052] During the structural design process, it is possible that the overhanging surface of the structure is too large or the span is too large. In such a case, the load that the joint surface of the structural member itself can bear is limited. Therefore, a reinforcing plate, commonly known as the reinforcing rib 305, is added on the common vertical plane of the two combined bodies to increase the strength of the joint surface.

[0053] By fixing the support frame 3 at the seat base plate 2 and the strengthening and fixing structure 4, and fixing the reinforcing ribs 305 on the support frame 3, the strength of the seat base plate 2 can be greatly improved, enabling the seat to carry more passengers. Moreover, both the seat base plate 2 and the backrest base plate 1 are galvanized steel plates, which can extend the service life and bring convenience.

[0054] Zinc is a very active metal and extremely easy to oxidize. However, zinc oxide is not a loose powder like iron oxide, but a dense surface layer. This zinc oxide layer prevents the further oxidation of the internal zinc. When the surface layer of the galvanized steel plate is damaged and the internal iron surface is exposed, since zinc is more active than iron, according to the chemical battery principle, zinc will oxidize prior to iron, thus protecting the iron layer from damage. The combination of these two aspects is the principle of galvanized steel plate protection.

[0055] A processing method for a galvanized steel plate base for rail transit seat installation, the processing steps are divided into two major steps, which are respectively manufacturing the galvanized steel plate and the installation and fixation between the plates.

[0056] Further, the steps for manufacturing the galvanized steel plate are as follows:

[0057] A1: Select raw materials. Select carbon element, chromium element, manganese element, palladium element, molybdenum element, iron element and copper element as the raw materials for making the steel plate.

[0058] A2: Preliminary refining. Put the iron element and copper element in A1 into a blast furnace for preliminary refining.

[0059] A3: Improve purity. Take out the refined materials in A2 above and put them into a converter for further refining to improve purity.

[0060] A4: Improve quality. Take out the materials refined in A3 above and put them into a refining steel furnace for refining. At the same time of refining, add appropriate amounts of carbon element, chromium element, manganese element, palladium element and molybdenum element for refining.

[0061] A5: Cool the mold. After refining is completed, take out the molten steel, invert it on the mold for cooling to obtain steel blocks.

[0062] A6: Galvanize. Fix and weld a reinforcing plate layer 602 on the steel block and galvanize it to obtain a galvanized steel plate.

[0063] The preliminary refining is to melt iron ore and copper ore into molten steel for subsequent processing. The process of improving purity is to purify the molten steel obtained from blast furnace steelmaking, remove impurities, and obtain relatively pure molten steel. The process of improving quality is to adjust the composition of the molten steel and add other metal or non-metal elements to ensure the quality of the steel. The molten steel refined through the above process is poured into a mold and cooled and solidified to obtain a steel billet. In modern industry, continuous casting machines are usually used for large-scale production of steel, which can continuously pour molten steel and continuously output steel billets.

[0064] Furthermore, the content of carbon element used is wc 0.65%, the content of molybdenum element used is 1%, the blast furnace is a self-standing blast furnace, and the mold is a mold for the base of a rail transit seat.

[0065] Furthermore, the installation and fixation steps between the plates are as follows:

[0066] S1: Fix the strengthening and fixing structure 4. Align the strengthening and fixing structure 4 with the slot holes opened in the seat substrate 2, push the strengthening and fixing structure 4 into it, and the protruding latch 501 reaches deep into the fixing hole 201 and pops out and gets stuck under the action of the spring 504. Rotate the screw block to fix the strengthening and fixing structure 4 on the seat substrate 2.

[0067] S2: Fix the support frame 3. Align the support frame 3, take out the screws, and fix the fixed mounting plate 303 on the lower surfaces of the strengthening and fixing structure 4 and the seat substrate 2.

[0068] S3: Weld the backrest substrate 1. Weld the backrest substrate 1 on the seat substrate 2 to complete the installation and processing between the plates.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
