Abstract
The invention discloses an anti-drop torsional spring, which comprises a first side and a second side, wherein the first side and the second side form an approximate splayed shape; the upper ends of the first side and the second side are combined to form a circle; the tail ends of the first side and the second side are provided with U-shaped parts; and the openings of the U-shaped parts at the tail ends of the first side and the second side are opposite. According to the anti-drop torsional spring, the tail ends of the first side and the second side are provided with the U-shaped parts, and the openings of the U-shaped parts at the tail ends of the first side and the second side are opposite, so that the torsional spring can be prevented from scratching the inner wall of a fuel tank body when taken out. The anti-drop torsional spring is simple in structure and practical.
Description
Technical field
The present invention relates to a kind of torsion spring, especially a kind of Drop-proof torsion spring that prevents to scratch the fuel tank body belongs to the component technology field of motor.
Background technique
The fuel tank of present outboard machine, fuel tank cap is tightened on the fuel tank body; Said fuel tank cap connects a Drop-proof torsion spring through a chain, and shown in accompanying drawing 1, said Drop-proof torsion spring comprises first limit 1, second limit 2; Said first limit 1, second limit 2 form one and roughly are splayed shape, and said first limit 1 combines with the upper end on second limit 2, forms a circle 3; The end on said first limit 1, second limit 2 is open shape setting; The fuel tank of this structure, though can realize the function that prevents that fuel tank cap from coming off, when maintenance or replacings need be taken off fuel tank cap, the end on said first limit, second limit was easy to the scratch inner wall of oil tank, even caused the fuel tank leakage.
Summary of the invention
The present invention seeks to have proposed a kind of Drop-proof torsion spring that prevents to scratch the fuel tank body for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the present invention adopts is: a kind of Drop-proof torsion spring comprises first limit, second limit; Said first limit, second limit form one and roughly are splayed shape, and said first limit combines with the upper end on second limit, forms a circle; The end on said first limit, second limit is provided with U-shaped portion; The opening of the U-shaped portion of the end on said first limit, second limit is oppositely arranged.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Drop-proof torsion spring of the present invention, the end on said first limit, second limit is provided with U-shaped portion; The opening of the U-shaped portion of the end on said first limit, second limit is oppositely arranged, and this structural design can prevent that the Drop-proof torsion spring from scratching the fuel tank inner body wall when taking out; This programme is simple in structure, practicality.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the plan view of the Drop-proof torsion spring of this existing technology;
Accompanying drawing 2 is the plan view of Drop-proof torsion spring of the present invention;
Wherein: 1, first limit; 2, second limit; 3, circle; 11, first limit; 12, second limit; 13, circle; 14, U-shaped portion.
Embodiment
Of the present invention a kind of Drop-proof torsion spring shown in accompanying drawing 2 comprises first limit 11, second limit 12; Said first limit 11, second limit 12 form one and roughly are splayed shape, and said first limit 11 combines with the upper end on second limit 12, forms a circle 13; The end on said first limit 11, second limit 12 is provided with U-shaped portion 14; The opening of the U-shaped portion 14 of the end on said first limit 11, second limit 12 is oppositely arranged.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Drop-proof torsion spring of the present invention, the end on said first limit, second limit is provided with U-shaped portion; The opening of the U-shaped portion of the end on said first limit, second limit is oppositely arranged, and this structural design can prevent that the Drop-proof torsion spring from scratching the fuel tank inner body wall when taking out; This programme is simple in structure, practicality.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
