[0027] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application, and obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0028] The utility model provides an easy installation's lower plate of anticorrosion as Figures 1-4 As shown in the corrosion -resistant easy installation's lower plate, comprising:

[0029] Plate body 1

[0030] Guard plate 2 is arranged at the bottom of plate body 1

[0031] Bolt hole 4 is set up at the bottom of guard plate 2, and bolt hole 4 is used for inserting installation bolt

[0032] Shielding piece 3 is arranged at the bottom of guard plate 2, and shielding piece 3 is used for shielding bolt.

[0033] Shielding piece 3 includes:

[0034] Shielding plate 31 is connected with bolt hole 4 and is inserted

[0035] Limiting rod 32 is fixedly connected with the outer wall of shielding plate 31 at the end.

[0036] The top of guard plate 2 is provided with insertion slot 5 for inserting limiting rod 32.

[0037] One side of the inner wall of insertion slot 5 is provided with rotating slot 6 for rotating limiting rod 32.

[0038] Further, the plate body 1 is the lower guard plate of the existing car, which is fixedly connected with the frame body at the bottom of the car through bolts, and the protective plate 2 is made of polyvinyl chloride material. Polyvinyl chloride (PVC) is a widely used plastic material with many advantages. The main benefits of polyvinyl chloride material are as follows: 1. Excellent corrosion resistance: PVC has good resistance to many chemicals, including acids, bases, salts and organic solvents; 2. Mechanical strength and durability: rigid PVC has high mechanical strength and rigidity, and can withstand certain pressure and impact.It also has good wear resistance and anti-aging properties, and can maintain its physical properties for a long time; 3. Lightweight: PVC material is relatively lightweight, making it easy to transport and install; 4. Insulation properties: PVC has excellent electrical insulation properties; 5. Processability: PVC material is easy to process and can be made into various shapes through extrusion, injection molding, blow molding, thermoforming and other processes, which allows PVC to meet diverse application needs; 6. Weather resistance: PVC has good weather resistance and can be used in outdoor environments for a long time without aging. It has good resistance to ultraviolet rays, temperature changes and humidity changes; 7. Cost-effectiveness: PVC PVC has relatively low production costs and is easy to mass-produce, making it an economical material widely used in various fields; 8. Environmental protection and recyclability: PVC is a recyclable material, and its environmental impact can be reduced through recycling and reuse. Furthermore, the chlorine used in the PVC production process can have its negative environmental impact reduced through recycling and closed-loop treatment; 9. Flame retardancy: PVC has self-extinguishing properties, meaning it automatically extinguishes itself after the flame is removed. Simultaneously, the shape of the top of the protective plate 2 matches the shape of the bottom of the plate 1, and the size of the protective plate 2 corresponds to the size of the plate 1, thus covering the plate 1. The protective plate 2 opens... The position and size of the bolt hole 4 correspond to the position and size of the bolt holes on the plate 1. By inserting bolts into the bolt holes 4, the protective plate 2 and the plate 1 can be fixedly installed to the vehicle frame. The materials of the baffle plate 31 and the limiting rod 32 are the same as those of the protective plate 2. Two limiting rods 32 are provided, symmetrically arranged on both sides of the outer wall of the baffle plate 31. The ends of the limiting rods 32 that contact the outer wall of the baffle plate 31 are connected by heat fusion. The number of insertion slots 5 and rotation slots 6 corresponds to the number of limiting rods 32. A slot is provided at the end of the baffle plate 31 away from the bolts for inserting a rotating tool. The thickness of the limiting rod 32 is 0.8 times the height of the rotation groove 6 when the baffle plate 31 rotates. By inserting the baffle plate 31 into the bolt hole 4 and simultaneously inserting the limiting rod 32 into the insertion groove 5, the bolt inserted into the bolt hole 4 can be covered. Then, the baffle plate 31 is rotated, and the baffle plate 31 drives the limiting rod 32 to rotate inside the corresponding rotation groove 6. Under the restriction of the rotation groove 6, the limiting rod 32 cannot move vertically, so the baffle plate 31 will not fall out of the bolt hole 4, thus ensuring continuous coverage of the bolt and preventing rainwater from splashing with the wheels and coming into contact with the bolt, causing rust at the bolt threads and affecting the disassembly of the plate 1.

[0039] In Embodiment 2, the present invention provides a limiting block 7, which is applied to the lower packaging plate in Embodiment 1. The top end of the inner wall of the rotating groove 6 is fixedly connected to the limiting block 7 for limiting the movement of the limiting rod 32.

[0040] The vertical cross-section of the limiting block 7 is semi-circular.

[0041] Furthermore, the limiting block 7 is made of fluororubber, which has the following properties: 1. Excellent chemical corrosion resistance: Fluororubber has extremely strong chemical corrosion resistance, resisting the erosion of most organic solvents, acids, alkalis, oils, fuels, and oxidants. It can even be used for a long time in corrosive media under high temperature and high pressure; 2. Excellent high temperature resistance: Fluororubber can maintain its physical and chemical properties at high temperature environments. Generally, fluororubber can work for a long time at temperatures above 200°C, and can even withstand temperatures of 250°C or higher for short periods; 3. Low temperature resistance: Although the low temperature resistance of fluororubber is not as good as its high temperature resistance, it can still maintain good performance in the temperature range of -20°C to -30°C. 4. Good resilience: Fluororubber has good elasticity; 5. Flame retardancy: Fluororubber has certain flame retardant properties and can slow down combustion under high temperature and fire source; thus, it can be used for a longer time at the bottom of the protective plate 2. The limiting block 7 is fixed to the inner wall of the rotating groove 6 by adhesive. When the limiting rod 32 rotates, it will restrict the limiting block 7, so that the limiting rod 32 cannot move out of the rotating groove 6 without external force, thus ensuring the stability of the baffle plate 31 installed inside the bolt hole 4. When external force is applied to the baffle plate 31, the baffle plate 31 drives the limiting rod 32 to rotate, and the limiting rod 32 will squeeze and deform the limiting block 7, so that the limiting rod 32 moves out of the rotating groove 6.
