Description

A kind of double loop shell fragment

Technical field

This utility model is related to shell fragment design field, specially a kind of double loop shell fragment.

Background technology

Shell fragment is for the instrument in machinery, the buffer anti-seismic device of vehicle and relay deferred mount, and the feature of shell fragment is, Only it is easily bent in a direction minimum rigidity plane, and there is big tensible rigidity in the other directions and bend just Degree.Therefore, flat spring is very suitably for doing the sensing element in instrumentation or automaton, elastic bearing, positioner, scratching Property connect etc..

The design of existing shell fragment only one of which loop, works long hours and has Fracture Failure Risk, in the people being operated Member produces great life threat, and existing product design structure, and bullet is hanging, and elastic force can be less than normal, and conductivity can be partially Little, affect work efficiency.

Utility model content

The purpose of this utility model is to provide a kind of double loop shell fragment, possesses the first loop and second servo loop, spring energy Enough come into force, elastic force can increase simultaneously, thus strengthening conductivity, and at work, if one of partial failure, also one Loop can work, and significantly serves the effect of protection.

For achieving the above object, this utility model provides following technical scheme：A kind of double loop shell fragment, including anti-scraper plate, Phase III and the 5th stage, by snapping connection baffle plate on described anti-scraper plate, described anti-scraper plate base plate is sequentially connected first Stage, second stage, phase III, fourth stage and the 5th stage, the described first stage is the spring that little radian is bent upwards In the stage, radius of curvature is less, and the described first stage is provided with second stage away from one end of anti-scraper plate, and described second stage is big arc Spend the spring stage to the bending of anti-scraper plate direction, radius of curvature is larger, and described second stage is provided with away from one end of first stage Phase III, the described phase III is the spring stage that big radian is bent upwards, and radius of curvature is big, and the described phase III is away from the One end of two-stage is provided with fourth stage, and described fourth stage is the big radian reclinate spring stage, and radius of curvature is larger, Described fourth stage was provided with for the 5th stage away from one end of phase III, and described 5th stage is the straight line with certain gradient In the spring stage, on the downside of described 5th stage, it is provided with a c-type loop structure.

Preferably, described first stage, second stage and phase III are combined as the first loop.

Preferably, described fourth stage, the 5th stage and c-type loop structure are combined as second servo loop.

Preferably, described phase III and fourth stage junction are contact point.

Preferably, described fourth stage is provided with perforate.

Compared with prior art, the beneficial effects of the utility model are as follows：

1st, this utility model passes through to arrange the first loop and second servo loop can make elastic force come into force, thus strengthening bullet simultaneously Power, increases conductivity.

2nd, by arranging the first loop and second servo loop, this utility model can accomplish that one of loop is another after damaging Individual loop normally uses, and serves protective effect.

Brief description

Fig. 1 is this utility model structural representation；

Fig. 2 is this utility model perspective view.

In figure：1 anti-scraper plate, 2 baffle plates, 3 first stage, 4 second stage, 5 phase IIIs, 6 fourth order Section, 7 the 5th stages, 8 c-type loop structures.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

Refer to Fig. 1-2, this utility model provides a kind of technical scheme：A kind of double loop shell fragment, including anti-scraper plate 1, Three stages 5 and the 5th stage 7, by snapping connection baffle plate 2 on described anti-scraper plate 1, described anti-scraper plate 1 base plate is sequentially connected One stage 3, second stage 4, phase III 5, fourth stage 6 and the 5th stage 7；The described first stage 3 is bent up for little radian In the bent spring stage, radius of curvature is less, and the described first stage 3 is provided with second stage 4 away from one end of anti-scraper plate 1；Described In the spring stage that two-stage 4 bends to anti-scraper plate 1 direction for big radian, radius of curvature is larger, and described second stage 4 is away from first The one end in stage 3 is provided with the phase III 5；In the spring stage that the described phase III 5 is bent upwards for big radian, radius of curvature is big, The described phase III 5 is provided with fourth stage 6 away from one end of second stage 4；Described fourth stage 6 is that big radian is reclinate In the spring stage, radius of curvature is larger, and described fourth stage 6 was provided with for the 5th stage 7 away from one end of phase III 5；Described 5th Stage 7 is the linear springs stage with certain gradient, is provided with a c-type loop structure 8 on the downside of described 5th stage 7.
