[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In this embodiment, a sliding plate 12 is fixedly connected to the lower end of the movable rod 8 , and sliding blocks 11 are fixedly connected to both sides of the sliding plate 12 .

[0025] In this embodiment, a slide groove 10 is provided inside the connecting member 1 , and the sliding block 11 slides in the connecting member 1 through the slide groove 10 .

[0026] In this embodiment, an inner through hole 13 is formed in the movable rod 8 , and an outer through hole 14 is formed in the connecting member 1 .

[0027] In this embodiment, a second anti-corrosion layer 102 is provided on the periphery of the outer through hole 14 in the connecting member 1 .

[0028] Among them, through the setting of the second anti-corrosion layer 102, a thin film can be formed on the periphery of the connector 1 with the external through hole 14, so as to protect the periphery of the connector 1 with the external through hole 14, so that the connector 1 can be better adapted to the interior of the car, and the service life of the connector 1 can also be increased. The number of the internal through hole 13 and the external through hole 14 are both two.

[0029] It should be noted that the second anti-corrosion layer 102 is epoxy anti-corrosion paint.

[0030] It can be understood that epoxy anti-corrosion paint is a type of coating with epoxy resin as the main film-forming substance. It has excellent chemical resistance, corrosion resistance and adhesion, and is suitable for the anti-corrosion protection of metal and non-metallic substrates in various environments. Epoxy anti-corrosion paint can resist the erosion of acids, alkalis, salt water, chemicals, solvents and microorganisms, etc., and is therefore widely used in chemical, pharmaceutical, water conservancy, construction, petroleum, transportation and other industries.

[0031] The characteristics of epoxy anti-corrosion paint include:

[0032] Good adhesion: Epoxy resin can form a strong adhesion to a variety of substrate surfaces, especially to metal surfaces.

[0033] Corrosion resistance: Epoxy resin itself has good chemical resistance, and its cross-linked structure makes epoxy anti-corrosion paint resistant to a variety of corrosive media.

[0034] Wear resistance: The epoxy anti-corrosion paint coating has high hardness and good wear resistance, and is suitable for environments with mechanical wear.

[0035] Durability: Epoxy coating can maintain its performance even when exposed to harsh environment for a long time and has a long service life.

[0036] Easy construction: Epoxy anti-corrosion paint can be applied by brushing, spraying, roller coating and other methods.

[0037] Strong adaptability: Epoxy anti-corrosion paint can adapt to construction requirements under different temperature and humidity conditions.

[0038] There are many types of epoxy anti-corrosion paints, which can be divided into the following categories according to the curing method and purpose:

[0039] Solvent-based epoxy anti-corrosion paint: usually uses organic solvents as dispersion media, has good construction performance and adhesion, but has certain pollution to the environment during the drying process.

[0040] Epoxy solvent-free anti-corrosion paint: does not contain solvents, has good environmental performance, and low volatile organic compound emissions during construction.

[0041] Epoxy powder coating: With epoxy resin as the main component, it is cured by baking and is suitable for coating lines with a high degree of automation.

[0042] Epoxy water-based anti-corrosion paint: uses water as the dispersion medium, which is environmentally friendly and reduces the risk of fire, but the construction performance and chemical resistance may be slightly inferior to the solvent type.

[0043] When selecting and using epoxy anti-corrosion paint, factors such as the type of substrate, the corrosiveness of the environment, the thickness of the coating, the construction method, and cost-effectiveness need to be considered to ensure the best anti-corrosion effect.

[0044] In this embodiment, an anti-corrosion layer 101 is provided on the outer side and inner wall of the connecting member 1.

[0045] Among them, through the setting of the anti-corrosion layer 101, a thin film can be formed on the outer side and inner wall of the connector 1 to protect the outer side and inner wall of the connector 1, so that the connector 1 can be better adapted to the interior of the car, and the service life of the connector 1 can also be increased.

[0046] It should be noted that the anti-corrosion layer 101 is an epoxy resin coating.

[0047] It is understandable that epoxy resin coating is a kind of coating with high adhesion, chemical resistance and corrosion resistance, which is widely used in construction, industry, shipbuilding, electrical equipment and other fields. In the preparation process of epoxy resin coating, different curing agents, fillers and additives are usually required to meet different application requirements.

[0048] The curing process of epoxy resin coating is a chemical reaction. Through cross-linking reaction, a three-dimensional network structure is formed, which makes the coating have higher hardness and strength. During the curing process, epoxy resin coating can form a tight coating, effectively preventing the penetration of moisture, oxygen and other harmful substances, thereby improving the corrosion resistance and wear resistance of the substrate.

[0049] The working principle of the above embodiment is:

[0050] First, the pipes to be connected in the automobile parts are connected through the connector 1, the connector 1 is initially fixed by the tightening nut 2, and the reliability of the connector 1 when connecting the pipe is enhanced by the locking nut 3.

[0051] Secondly, the limiting rod 6 is fixed in the connecting member 1 by the fixing plate 4. When water penetrates into the connecting member 1, the liquid penetrates into the lower part of the connecting member 1 through the guide hole 5. The pressure of the liquid on the sliding plate 12 can make the sliders 11 on both sides of the sliding plate 12 slide on the inner wall of the connecting member 1, and the movable rod 8 is driven to move by the sliding plate 12. Among them, the movable rod 8 can be limited in the limiting rod 6 by the reset spring 7. When the movable rod 8 moves to the appropriate position, the inner through hole 13 in the movable rod 8 is connected with the outer through hole 14 in the connecting member 1. At this time, the liquid that penetrates into the connecting member 1 can be discharged from the connecting member 1, so as to achieve the advantages of enhancing the service life of automobile parts.

[0052] Finally, the anti-corrosion layer 1 101 disposed on the inner wall of the connector 1 and the anti-corrosion layer 2 102 disposed on the outer periphery of the outer through hole 14 of the connector 1 can both enhance the corrosion resistance of automobile parts.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
