The extension spring that a kind of shipping container is used, comprise resilient member, the first pull bar, the second pull bar, described resilient member left part is provided with the first dunnage, right part is provided with the second dunnage, described the first pull bar through being fixedly connected with the second dunnage the first dunnage, makes the first pull bar can be with respect to the first dunnage translation from left side; Described the second pull bar through being fixedly connected with the first dunnage the second dunnage, makes the second pull bar can be with respect to the second dunnage translation from right side.
Be further used as preferred embodiment, described the first pull bar is U-shaped member, has curved end and opening end, and described opening end is fixedly connected with the second dunnage.
Be further used as preferred embodiment, described the second pull bar is U-shaped member, has curved end and opening end, and described opening end is fixedly connected with the first dunnage.
Be further used as preferred embodiment, described the first pull bar entirety is in A plane, and the second pull bar entirety is in B plane, and described A plane and B plane are orthogonal to intersect, and the center line of the first pull bar, the second pull bar is the intersection of this two plane.
Be further used as preferred embodiment, described the first pull bar is being provided with near its curved end place the location piece or the positioning block that are positioned at the first dunnage left; Described the second pull bar is being provided with and is being positioned at right-hand location piece of the second dunnage or positioning block near its curved end place.
Be further used as preferred embodiment, described resilient member is a Compress Spring.
Be further used as preferred embodiment, described resilient member comprises the Compress Spring of two above arranged in series, is also provided with dividing plate between Compress Spring, and described the first pull bar and the second pull bar can pass dividing plate and can be with respect to dividing plate translation.
The beneficial effects of the utility model are: changed the structure of extension spring, its cost manufacture is reduced, reliability improves, and lengthen working life.The extension spring that described shipping container is used can be applicable to Container Transport field.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than whole embodiment, and those skilled in the art is not paying under the prerequisite of creative work, can also obtain other design proposals and accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of traditional extension spring;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to understand fully the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite of not paying creative work, all belong to the scope that the utility model is protected.In addition, all connection/annexations of mentioning in literary composition, not singly refer to that member directly joins, and refer to and can, according to concrete performance, by adding or reducing, connect auxiliary, form more excellent connecting structure.Each technical characteristics in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
As shown in Figure 2, the extension spring that a kind of shipping container is used, comprise resilient member 3, the first pull bar 1, the second pull bar 2, described resilient member 3 left parts are provided with the first dunnage 4, right part is provided with the second dunnage 5, described the first pull bar 1 through being fixedly connected with the second dunnage 5 the first dunnage 4, makes the first pull bar 1 can be with respect to the first dunnage 4 translations from left side; Described the second pull bar 2 through being fixedly connected with 4 with the first dunnage the second dunnage 5, makes the second pull bar 2 can be with respect to the second dunnage 5 translations from right side.By adding pull bar and dunnage, make the power of the suffered outside stretching of extension spring change the power of being born inside compression by resilient member 3 into, even thereby resilient member 3 adopt the more cheap 60Si2MnA spring steel of price also can make the rigidity of extension spring reach the rigidity levels of the extension spring of being manufactured by SAE9254 spring steel.Moreover, because pull bar is member independently, can adopt separately high-intensity material, while avoiding work, there is the undesirable condition of fracture.
Be further used as preferred embodiment, described the first pull bar 1 is U-shaped member, has curved end and opening end, and described opening end is fixedly connected with the second dunnage 5.The working strength of the pull bar of U-shaped is higher, is not easy to occur fracture, only needs collocation shackle can realize the function of the drag hook part of traditional extension spring.
