Abstract
The utility model discloses a double-tension spring damping structure, wherein a first tension spring comprises a first ear hook and a first spring body; the first ear hook is arranged at one end of the first spring body; the other end of the first spring body is provided with one end of a connecting rod; a second tension spring comprises a second ear hook and a second spring body; the other end of the connecting rod is arranged at one end of the second spring body; the second ear hook is arranged at the other end of the second spring body; a damping protection sleeve is arranged on the connecting rod; the first spring body and the second spring body are tapered screw bodies with the same size, and a strengthened layer is arranged on the surface of each tapered screw body. In this way, the double-tension spring damping structure adopts the combination of two tension springs with the same size, is balanced in stress, small in carrying capacity of evenly stressed springs and high in fatigue life; and the damping protection sleeve is arranged between the two tension springs. Therefore, the damping effect is effectively achieved; the fatigue resistance is effectively improved by the strengthened layer, and the service life is also prolonged.
Description
Technical field
The utility model relates to the spring field, particularly relates to the two extension spring structures of a kind of damping.
Background technique
At present, for the stage clip damping is adopted in damping mostly, but the stage clip diameter is little, and elastic force and rope stroke are all less, and effect of easing stress is not good enough, can not be according to accepting the situation adjustment, and stressed when larger, produce easily distortion, even cause for a long time and can't restore to the original state.
The problems such as then people select extension spring to replace stage clip, but the extension spring structure of existing structure still can't have good damping effect, wait in use also to have fatiguability, and it is larger to wear and tear.
The model utility content
The technical problem that the utility model mainly solves provides the two extension spring structures of a kind of damping, can effectively reach the purpose of damping, and is stressed even, long service life.
For solving the problems of the technologies described above; the technological scheme that the utility model adopts is: provide a kind of damping two extension spring structures; comprise: the first extension spring; the second extension spring; connect as one by connecting rod between described the first extension spring and the second extension spring; described the first extension spring comprises the first tack; the first spring body; described the first tack is located at described the first spring body one end; the described first spring body the other end is provided with described connecting rod one end; described the second extension spring comprises the second tack; the second spring body; the described connecting rod the other end is located at described the second spring body one end; the described second spring body the other end is provided with described the second tack; described connecting rod is provided with the shock-absorbing protecting cover; described the first spring body and the second spring body are the trochoid spiral body of same size, and described trochoid spiral surface is provided with strengthened layer.
In preferred embodiment of the utility model, described connecting rod is lineal shape, U-shaped.
In preferred embodiment of the utility model, described the first spring body and the second spring body are the cylindrical screw body.
In preferred embodiment of the utility model, described shock-absorbing protecting cover is plastics, nylon.
In preferred embodiment of the utility model, described strengthened layer is the shot blast layer.
In preferred embodiment of the utility model, fixed cover is provided with described shock-absorbing protecting cover on the described tack.
The beneficial effects of the utility model are: the two extension spring structures of the utility model damping adopt the extension spring combination of two same sizes, stress equalization, and the stressed bearing capacity of sharing rear spring equally is less, and fatigue life is high; Between two extension springs, be provided with the shock-absorbing protecting cover, effectively reach the effect of damping; The strengthened layer Effective Raise fatigue resistance, increase the service life.
Description of drawings
Fig. 1 is the structural representation of two extension spring structure one preferred embodiments of the utility model damping;
The mark of each parts is as follows in the accompanying drawing: 1, the first tack, the 2, first spring body, 3, connecting rod, the 4, second tack, the 5, second spring body, 6, the shock-absorbing protecting cover.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model is embodiment comprise:
The two extension spring structures of a kind of damping, comprise: the first extension spring, the second extension spring, connect as one by connecting rod 3 between described the first extension spring and the second extension spring, described the first extension spring comprises the first tack 1, the first spring body 2, described the first tack 1 is located at described the first spring body 2 one ends, described the first spring body 2 the other ends are provided with described connecting rod 3 one ends, described the second extension spring comprises the second tack 4, the second spring body 5, described connecting rod 3 the other ends are located at described the second spring body 5 one ends, and described the second spring body 5 the other ends are provided with described the second tack 4.
It is stressed that two extension spring structures used the extension spring of two same sizes to disperse, and makes stress equalization, and the stressed bearing capacity of sharing rear spring equally is less, is conducive to increase the service life.
Described connecting rod 3 is provided with shock-absorbing protecting cover 6, on the described tack also fixed cover be provided with described shock-absorbing protecting cover 6.Described shock-absorbing protecting cover 6 is plastic materials, nylon material.In the place that produces easily friction and vibrations, be provided with shock-absorbing protecting cover 6, effectively reduce vibrations.
Described the first spring body 2 and the second spring body 5 are trochoid spiral body or the cylindrical screw body of same size.Described trochoid spiral surface is provided with strengthened layer.Described strengthened layer is the shot blast layer.
Shot blast is a kind of surface intensified technique that factory extensively adopts, and its equipment is simple, with low cost, is not subjected to workpiece shape and position limitation, and is easy to operate, but working environment is relatively poor.Shot-peening is widely used in and improves part machinery intensity and wear resistance, antifatigue and corrosion resistance etc.Shot blast layer energy Effective Raise dual spring fatigue resistance increases the service life.
Described connecting rod 3 is lineal shape, U-shaped.Connecting rod 3 can according to the mounting point of the two extension spring structures of damping, be selected applicable shape, applied range.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
