Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a fuel tank float for automobiles and motorcycles.

[0002]

[Prior art]

 As shown in FIG. 1, a conventional float is prepared by mixing several types of foam materials into a mold, heating and pressurizing it, and then hardening it, and then entering it through a groove 11 on the front side and passing through the float 1. A through hole 12 is provided. The float 1 is fixed by being attached to the tip of the float lever through which the float lever penetrates the through hole 12 and the bundle ring penetrates.

[0003]

[Problems to be solved by the device]

 However, in the case of conventional floats, when heating and pressurization are insufficient, the voids of the foam material remain, and gasoline permeates and is absorbed in the gaps of the foam material, increasing the weight and functioning as a float. I will lose. Therefore, the sensor device that detects the amount of gasoline fails.

Further, when the gasoline soaks into the float from the inner surface of the through hole 12 and a long period of time elapses, the foam material is damaged. Then, this invention aims at providing the float which solved the said subject.

[0005]

[Means for Solving the Problems]

 The present invention has a structure in which a body made of reinforced plastic containing fiber glass and a hermetically sealed body, which are both injection-molded, are joined to each other by high-frequency welding in a float attached to a float lever in a vehicle fuel tank. The main body has a fitting groove having a V-shaped cross section on the front side, and a groove having an opening width narrower than the diameter of the float lever inside the fitting groove, It has a pipe portion extending to the filter side, a float lever is inserted into the pipe portion, and the float lever is fitted into the groove.

[0006]

[Embodiment of device]

 2, 3 and 4 show a float 2 according to the present invention. The float 2 includes a main body 21 and a closed body 22. Both the main body 21 and the sealing body 22 are injection molded parts made of fiberglass-reinforced plastic. The main body 21 has a fitting groove 211. The fitting groove 211 has a V-shaped cross section in which the front side is wide and the inner part is narrow. Another groove 212 is formed inside the fitting groove 211. The width of the opening of the groove 212 is smaller than the diameter of the float lever 3. A tubular portion 213 having an appropriate length and having a tubular shape is provided so as to extend rearward from a central portion of the groove 212. The float lever 3 is inserted into the tube portion 213.

The closed body 22 has a cylindrical shape and has an opening on the front side. The rear side of the main body 21 is fitted in the front side opening of the closed body 22, and both are integrated by high frequency welding. In the float 2, the tip portion 32 of the float lever 3 whose tip side is bent into an L-shape is inserted into the tube portion 213, and the curved portion 31 of the float lever 3 is fitted into the groove 212, so that the float lever 3 It is attached to the tip side of.

Here, since the pipe portion 213 into which the float lever 3 is inserted is provided so as to extend rearward from the central portion of the groove 212, the inner portion of the pipe portion 213 and the inside of the float 2 are isolated. . The float 2 is made of fiberglass reinforced plastic and has high corrosion resistance. Therefore, when the float 2 is immersed in the gasoline in the fuel tank, the gasoline penetrates the pipe portion 213, but the gasoline does not enter the float 2. Therefore, the weight of the float 2 is not increased and the buoyancy is not lost, and the float 2 is not damaged.

Further, when the curved portion 31 of the float lever 3 is fitted into the groove 212, the curved portion 31 is easily fitted by being guided by the fitting groove 211 having a wide front side. Since the opening of the groove 212 is narrower than the diameter of the float lever 3, the curved portion 31 fitted in the groove 212 is stably fixed in the groove 212 and rattles in the groove 212 or is not in the groove 212. It does not happen that you get out of and come off.

As shown in FIG. 3, the other end of the float lever 3 is attached to the sensor 4. FIG. 3 shows a gasoline quantity sensor device.

[0011]

[Effect of device]

 As described above, according to the present invention, the main body made of reinforced plastic containing fiberglass and the sealing body are joined together by high frequency welding, and the main body has a V-shaped cross section on the front side. In the inside of the fitting groove, there is a fitting groove, and there is a groove inside the fitting groove whose opening width is narrower than the diameter of the float lever and which extends rearward from the center of the groove. Since the float lever is inserted in and the float lever fits in the groove, gasoline can be prevented from entering the float, and the weight of the float increases and the buoyancy is lost. It can be avoided and damage to the float can be prevented.

Further, when the float lever is fitted into the groove, it can be fitted easily by being guided by the fitting groove having a wide front side, and the assembling can be simplified. Also, since the opening of the groove is narrower than the diameter of the float lever, the float lever fitted in the groove is stably fixed in the groove and rattles in the groove or slips out of the groove and comes off. Can be prevented.
