Description

TECHNICAL FIELD

[0001] The utility model relates to the field of filling station, concretely is a kind of filling station saddle fastening bolt. BACKGROUND

[0002] Filling station, especially the filling station located in marine environment or coastal area, often faces the challenge of salt mist, sea fog and other adverse weather conditions.These environmental conditions have strong corrosive properties to metal structural components, which can cause structural component strength to decrease, connection to loosen or even fail.

[0003] The fastening mode of filling station saddle and other equipment is mostly rivet connection, but the rivet itself does not have sufficient corrosion resistance, especially in salt mist, sea fog and other harsh environments, the rivet is easily corroded, thereby affecting its connection strength and stability, and once the rivet is riveted, it is difficult to disassemble, which increases the difficulty of equipment maintenance and replacement, and also limits the maintainability and upgradability of the equipment. SUMMARY

[0004] In order to overcome the above-mentioned deficiencies, the utility model provides a kind of filling station saddle fastening bolt.

[0005] The technical scheme adopted by the utility model is as follows:

[0006] A kind of filling station saddle fastening bolt, including saddle, the top of saddle is laid seat pad, the top of seat pad is inserted with several bolt sleeves along two side edges, bolt sleeve is equidistantly and uniformly distributed, bolt sleeve penetrates the bottom of seat pad and saddle, bolt sleeve is inserted with bolt inside, the bottom end of bolt penetrates the bottom of bolt sleeve, the outer wall top of bolt is sleeved with stainless steel gasket one, stainless steel gasket one abuts the top of bolt sleeve, the bottom end outer wall of bolt is connected with nut, the top of nut has stainless steel gasket two and polytetrafluoroethylene gasket from bottom to top in sequence, stainless steel gasket two and polytetrafluoroethylene gasket are all sleeved on the outer wall of bolt, the top of polytetrafluoroethylene gasket abuts the bottom of bolt sleeve and the bottom of saddle, the top of stainless steel gasket two abuts the bottom of polytetrafluoroethylene gasket, the top of nut abuts the bottom of stainless steel gasket two, seat pad and bolt sleeve are made of polytetrafluoroethylene.

[0007] The utility model has the advantages that:

[0008] The bolt sleeve and seat pad made of polytetrafluoroethylene can withstand strong acid, strong alkali and other harsh environments, reducing the corrosiveness caused by environmental conditions, and the use of stainless steel gasket one, stainless steel gasket two and polytetrafluoroethylene gasket in combination further enhances the corrosion resistance of the structure.

[0009] If the rivet is directly embedded in the fastening mode, the corrosion resistance of the rivet is low, the surface treatment or other corrosion resistant materials need to be carried out on the rivet, and once the rivet is riveted, it is very difficult to disassemble, which increases the difficulty of replacement and maintenance, and the bolt plus polytetrafluoroethylene gasket structure can prevent the potential difference between the bolt and the aluminum alloy material, so that the structure protection effect is better and more corrosion resistant.
