Abstract
The utility model provides a kind of high strength shell fragment unlocking structure for blade, it comprises blade body and blade upper cover and shell fragment, described shell fragment is fixed on the both sides of blade upper cover by the mode of taking out hole riveted joint, shell fragment is also provided with the first convex closure, shell fragment generation bending can be made by pressing the first convex closure, the shell fragment lower edges taking out riveted joint position, hole at described shell fragment and blade upper cover kills limit, and when pressing the first convex closure, the position of shell fragment generation bending arranges the second convex closure.The utility model is on the basis of original structure, the shell fragment lower edges taking out riveted joint position, hole at described shell fragment and blade upper cover kills limit, also when pressing the first convex closure, the second convex closure has been set up in the position of shell fragment generation bending, adds intensity and the elastic performance of shell fragment.
Description
Technical field
The utility model relates to a kind of stainless steel shell fragment, specifically a kind of high strength shell fragment unlocking structure for blade.
Background technique
Existing blade generally adopts the stainless steel shrapnel device of exempting from screw to realize blade and fastens, this stainless steel shrapnel device structure exempting from screw is simple, use and operate all very convenient, but, use this stainless steel shrapnel device of exempting from screw carry out card and and unlock process in, need shell fragment to have higher intensity and elastic performance, otherwise in the process used, easily phenomenon of rupture occurs thus cause trouble to using process.
, existing structure is optimized for this reason, is modified into a kind of high strength shell fragment unlocking structure, solves the problems referred to above, to avoid the unnecessary trouble caused in using process.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, avoiding the stainless steel shrapnel device of exempting from screw carrying out card and the phenomenon with easy generation fracture in the process unlocked, providing a kind of and there is high strength and the elastomeric high strength shell fragment unlocking structure for blade.
The utility model solves the technological scheme that its technical problem adopts:
A kind of high strength shell fragment unlocking structure for blade, comprise blade body and blade upper cover and shell fragment, described shell fragment is fixed on the both sides of blade upper cover by the mode of taking out hole riveted joint, shell fragment is also provided with the first convex closure, can make shell fragment generation bending by pressing the first convex closure, the shell fragment lower edges taking out riveted joint position, hole at described shell fragment and blade upper cover kills limit.
Further, when pressing the first convex closure, the position of shell fragment generation bending arranges the second convex closure.
As preferably, described shell fragment adopts stainless steel.
Compared with prior art, the beneficial effect produced is a kind of high strength shell fragment unlocking structure for blade of the present utility model:
1) the utility model is on the basis of original structure, and the shell fragment lower edges taking out riveted joint position, hole at described shell fragment and blade upper cover kills limit, directly increases the intensity of shell fragment, indirectly changes the elastic performance of shell fragment;
2) the utility model has also set up the second convex closure, is further increased intensity and the elastic performance of shell fragment by the thickness changing shell fragment.
3) the shell fragment lower edges that the utility model takes out riveted joint position, hole at described shell fragment and blade upper cover kills limit, when pressing the first convex closure, the position of shell fragment generation bending arranges the second convex closure, more importantly, still adopt stainless steel, the strength character for shell fragment provides good basis.
Accompanying drawing explanation
Accompanying drawing 1 is the structure for amplifying schematic diagram of the utility model specific embodiment one.
Accompanying drawing 2 is the structure for amplifying schematic diagram of the utility model specific embodiment two.
Accompanying drawing 3 is the mounting structure schematic diagram of existing structure.
In figure, 1, blade upper cover, 2, shell fragment, the 3, first convex closure, the 4, second convex closure.
A, take out hole riveted joint, B, kill limit.
Embodiment
Below in conjunction with accompanying drawing 1,2,3, a kind of high strength shell fragment unlocking structure for blade of the present utility model is described in detail below.
Specific embodiment one:
As shown in Figure 1, a kind of high strength shell fragment unlocking structure for blade of the present utility model, its structure comprises blade body and blade upper cover 1 and shell fragment 2, described shell fragment 2 is fixed on the both sides of blade upper cover 1 by the mode of taking out hole riveted joint A, shell fragment 2 is also provided with the first convex closure 3, can make shell fragment 2 that bending occurs by pressing the first convex closure 3, taking out shell fragment 2 lower edges of riveting A position in hole at described shell fragment 2 and blade upper cover 1 and killing limit B.
As preferably, described shell fragment 2 adopts stainless steel.
Specific embodiment two:
As shown in Figure 2, a kind of high strength shell fragment unlocking structure for blade of the present utility model, its structure comprises blade body and blade upper cover 1 and shell fragment 2, described shell fragment 2 is fixed on the both sides of blade upper cover 1 by the mode of taking out hole riveted joint A, shell fragment 2 is also provided with the first convex closure 3, can make shell fragment 2 that bending occurs by pressing the first convex closure 3, taking out shell fragment 2 lower edges of riveting A position in hole at described shell fragment 2 and blade upper cover 1 and killing limit B; The position that bending occurs shell fragment 2 when pressing the first convex closure 3 arranges the second convex closure 4.
As preferably, described shell fragment 2 adopts stainless steel.
By reference to the accompanying drawings 1,3, the utility model, on the basis of original structure, is taken out shell fragment 2 lower edges of riveting A position in hole at described shell fragment 2 and blade upper cover 1 and is killed limit B, directly increase the intensity of shell fragment 2, indirectly change the elastic performance of shell fragment 2;
By reference to the accompanying drawings 1,3, the utility model is on the basis of original structure, not only take out shell fragment 2 lower edges of riveting A position in hole at described shell fragment 2 and blade upper cover 1 and kill limit B, the second convex closure 4 has been set up in the position that also bending occurs shell fragment 2 when pressing the first convex closure 3, is further increased intensity and the elastic performance of shell fragment 2 by the thickness changing shell fragment 2.
In sum, the content of a kind of high strength shell fragment unlocking structure for blade of the present utility model is not limited in the above-described embodiments, those skilled in the art can propose other embodiment within guiding theory of the present utility model, but these embodiments are included within scope of the present utility model.
A kind of its processing and fabricating of high strength shell fragment unlocking structure for blade of the present utility model is simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characteristics described in specification, be the known technology of those skilled in the art.
