Description

Technical Field

[0001] The utility model mainly relates to the field of automobile fuel tanks, and particularly relates to a steel belt structure of an automobile fuel tank. Background Technique

[0002] The fuel tank, that is, the fuel storage device, has high requirements for corrosion resistance. At double working pressure, it should be sealed when the gauge pressure is at least 0.03 MPa. The generated overpressure must be self-relieved through holes or safety valves. When driving on a curve, an inclined road surface or being impacted, the fuel should not flow out from the liquid filling sealing cap or the pressure balancing device. The fuel tank must be installed away from the engine to prevent the fuel from being ignited in case of a traffic accident;

[0003] Among them, the automobile fuel tank is installed inside the automobile through a steel belt.

[0004] During the operation of specific embodiments, the inventor found the following defects:

[0005] The automobile fuel tank is connected to the automobile through multiple steel belts. However, during the connection process, due to the uneven bottom of the automobile fuel tank, there are still gaps between the steel belt and the automobile fuel tank, resulting in ineffective contact between the steel belt and the automobile fuel tank.

[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0032] Refer to the attached Figures 1-4 , an automobile fuel tank steel belt structure, comprising a steel belt support structure 1, wherein a fitting structure 2 is arranged inside the steel belt support structure 1, the number of the steel belt support structures 1 is set to be multiple, and the multiple steel belt support structures 1 are connected through a connection structure 3;

[0033] The fitting structure 2 includes a moving block 201 and a pushing bolt 207. A lifting plate 205 is arranged at the top of the pushing bolt 207. The lifting plate 205 is rotationally connected to the pushing bolt 207, and a fitting ring 206 is arranged at the top of the lifting plate 205;

[0034] Fit the fitting structure 2 at the top of the steel belt support structure 1 to the fuel tank, then connect the steel belt support structure 1 to the vehicle, and then connect the multiple steel belt support structures 1 through the connection structure 3, so as to connect the multiple steel belt support structures 1 into a whole. At the same time, rotate the pushing bolt 207, and the pushing bolt 207 drives the lifting plate 205 to move upward, and the lifting plate 205 drives the fitting ring 206 to fit with the bottom of the fuel tank.

[0035] Furthermore, the steel belt support structure 1 includes a steel belt body 101. Sealing rings 102 are arranged at the tops of both ends of the steel belt body 101. A fixing bolt 103 is rotationally connected inside the steel belt body 101. Fitting grooves 104 are formed on the outer walls of both sides of the steel belt body 101. A positioning bolt 106 is arranged inside the steel belt body 101. A guiding groove 105 is formed on the outer wall of the steel belt body 101. When it is necessary to install the steel belt support structure 1 at the bottom of the vehicle to support the automobile fuel tank, the sealing ring 102 fits with the bottom of the vehicle, and then rotate the fixing bolt 103. The fixing bolt 103 drives the steel belt body 101 to move upward and extrude the sealing ring 102, so as to stably fix the steel belt body 101.

[0036] Furthermore, an auxiliary strip 202 is provided at the bottom of the moving block 201. The auxiliary strip 202 is slidably connected to the guiding groove 105. A rotating rod 203 is rotatably connected to the top of the moving block 201. A positioning groove 204 is formed inside one end of the rotating rod 203. Positioning shafts 208 are provided at both ends of the lifting plate 205. Auxiliary grooves 209 are formed at both ends of the positioning shaft 208. A rotating shaft 210 is rotatably connected to the inner wall of the auxiliary groove 209. A circlip is provided between the rotating shaft 210 and the auxiliary groove 209. A limiting strip 211 is provided on the outer wall of the rotating shaft 210. After the steel belt support structure 1 is installed, the auxiliary strip 202 on one side of the moving block 201 is fitted to the guiding groove 105, and then the pushing bolt 207 is installed into the positioning bolt 106. After that, the positioning shafts 208 at both ends of the lifting plate 205 are inserted into the positioning groove 204, so that the positioning groove 204 squeezes the limiting strip 211. After the limiting strip 211 completely passes through the positioning groove 204, the flat spiral spring drives the rotating shaft 210 to reset, so that one end of the limiting strip 211 is fitted to the outer wall of the rotating rod 203, thereby fixing the moving block 201 and the steel belt body 101. Multiple fitting structures 2 can be installed on the outer wall of the steel belt support structure 1. After that, the pushing bolt 207 can be rotated. The pushing bolt 207 pushes the lifting plate 205 to move upward, so that the lifting plate 205 drives the rotating rod 203 to rotate and pulls the auxiliary strip 202 inside the moving block 201 to slide on the inner wall of the guiding groove 105. After that, the fitting ring 206 is fitted to the bottom of the car fuel tank.

[0037] Furthermore, the connecting structure 3 includes side support strips 301 and connecting strips 303. The side support strips 301 are arranged inside the fitting groove 104. Bolt holes 302 are formed at both ends of the side support strips 301. Screws 304 are rotatably connected to both ends of the connecting strip 303. The screws 304 are threadedly connected to the bolt holes 302. After the steel belt support structure 1 is installed, the side support strips 301 are fitted to the fitting groove 104, and then the connecting strip 303 is connected to the side support strips 301 through the screws 304 and the bolt holes 302.
