Abstract
The utility model relates to a spring which is widely used in the technical fields including machinery and the like, in particular to a drum type spring. The drum type spring comprises a spring body, a circlip is located in the middle of the spring body, and hooks are located at two ends of the spring. The drum type spring is characterized in that the circlip is of the structure of which the diameter in the middle is large and turns small sequentially toward two ends. The drum type spring of the structure has the advantages of being not prone to fatigue and damage and being durable in use under the condition that the diameter is larger.
Description
Technical field
The utility model relates to spring, and it is widely used in the technical fields such as machinery.
Background technique.
Spring comprises the spring body, circlip in the middle of the spring body, in prior art, the diameter of circlip equates, both ends of the spring is hook, in the situation that the circlip diameter is larger, coupling hook just has long dogleg section, such spring has the shortcoming of easy fatigue, damage, affects elasticity and using effect.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, provides a kind of in the situation that the larger indefatigability of diameter, non-damageable spring---a kind of barrel-shaped spring
The technical solution of the utility model is achieved in that a kind of barrel-shaped spring, comprises the spring body, is circlip in the middle of the spring body, and both ends of the spring is hook, and it is characterized in that: the diameter of described circlip is broad in the middle, the structure that diminishes successively to two ends.
The beneficial effects of the utility model are: such barrel-shaped spring has in the situation that the larger indefatigability of diameter, not fragile, long-lived advantage.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, spring body 2, hook 3, circlip.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of barrel-shaped spring comprises spring body 1, is circlip 3 in the middle of spring body 1, and both ends of the spring is hook 2, and it is characterized in that: the diameter of described circlip 3 is broad in the middle, the structure that diminishes successively to two ends.
