Abstract

The utility model relates to an anti-dropping torsion spring, which comprises a first side and a second side. The first side and the second side are arranged in intersecting mode, and the upper ends of the first side and the second side are combined to form a circle. A U-shaped part is disposed respectively at the tail ends of the first side and the second side. Openings of the U-shaped parts at the tail ends of the first side and the second side are arranged opposite to each other. Due to the structural design, the anti-dropping torsion spring is capable of avoiding scratching the inner wall of an oil tank body when the anti-dropping torsion spring is taken out, simple in structure and practical.

Description

A kind of Drop-proof torsion spring
Technical field
The utility model relates to a kind of torsion spring, and 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 are arranged in a crossed manner, 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 utility model purpose is 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 utility model adopts is: a kind of Drop-proof torsion spring comprises first limit, second limit; Said first limit, second limit are arranged in a crossed manner, 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 utility model compared with prior art has advantage:
The described Drop-proof torsion spring of the utility model, 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 the utility model technological scheme 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 the Drop-proof torsion spring of the utility model;
Wherein: 1, first limit; 2, second limit; 3, circle; 11, first limit; 12, second limit; 13, circle; 14, U-shaped portion.
Embodiment
The described a kind of Drop-proof torsion spring of the utility model shown in accompanying drawing 2 comprises first limit 11, second limit 12; Said first limit 11, second limit 12 are arranged in a crossed manner, 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 utility model compared with prior art has advantage:
The described Drop-proof torsion spring of the utility model, 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.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
