Abstract
The utility model belongs to firework industry, which particularly relates to a novel spherical shell of a firework cartridge. The utility model comprises two hemispherical shell bodies, wherein the mouth parts of the two hemispherical shell bodies are mutually combined and the two hemispherical shell bodies use a special mold for pressing environmental protection materials respectively. The utility model is characterized in that mutually sheathed geometric shapes are arranged on the combining surface between the mouth parts of the two hemispherical shell bodies; the spherical shapes are obtained through splicing operation, fixation and combination. As a result, the utility model solves the technical problems of deformation of spherical shells, no uniform distribution of the weight of spherical bodies, displacement of the circumference of a connecting mouth between the spherical shells, no uniform distribution between the strength of the connecting mouth and the integral strength of the spherical shells, etc. when the two spherical shell bodies of a firework cartridge are combined. Consequently, the firework cartridge has the favorable effects of air positioning, shaping of explosive bright beads and sound.
Description
Technical field
The utility model relates to the fireworks industry, is meant a kind of novel fire works display projectile shell especially.
Background technology
Display shell uses in red-letter day and great celebration occasion usually, and outward appearance is spherical, is formed by two hemispherical shell combination, and is porose on one of them hemispherical Shell, is used to install the special-purpose fuse primer (fuse cord is arranged in the fuse primer) of display shell.Prior art is to be combined as an orbicule after the two halves spherical shell is loaded firework powder respectively, with reference to Fig. 1, two halves spherical shell (1,2) connecting part is that the plane is folded mutually, poor in the prior art owing to manufacture craft, the two hemispheres hull shape is irregular, uneven and the easy dislocation of two hemispheres interface circumference during combination, need to use fixedly two halves spherical shell outer surface interface of adhesive tape 9, simultaneously, owing to the not equal reason of manually-operated time error, the fire works display projectile shell distortion after the combination makes the spheroid distribution of weight inhomogeneous, spherical shell interface explosion-proof weak strength behind the strip of paper used for sealing makes the whole explosion-proof intensity of spherical shell inhomogeneous.At present, the technical barrier of display shell manufacture technology field is to solve spherical shell shape and joint strength, and be the main cause that influences the display shell total quality a little less than the spherical shell out-of-shape, joint strength, because the spherical shell distortion causes the spheroid distribution of weight inhomogeneous, directly cause display shell launching trajectory instability a little less than the inhomogeneous and joint strength of spheroid distribution of weight, aerial locating effect is poor, the explosive forming weak effect, and effects,sound is poor.
The utility model content
Technical problems such as the purpose of this utility model is to provide a kind of novel fire works display projectile shell, and spherical shell distortion when solving the spherical shell combination of display shell two halves, distribution of weight are inhomogeneous, the circumference dislocation of spherical shell interface and joint strength and spherical shell overall intensity distribution are inhomogeneous.
The technical solution of the utility model is to realize like this, novel fire works display projectile shell, comprise the hemispherical housing (1,2) that two oral areas interosculate, described two hemispherical housings (1,2) adopt particular manufacturing craft that environment-friendly materials are suppressed respectively, it is characterized in that: have the geometry that socket-connects on described two halves spherical shell (1,2) the oral area faying face, be combined into spherical by being adhesively fixed.
Has the circular step face (3,4) that matches on described two halves spherical shell (1,2) the oral area faying face respectively.
Have circular fin 5 and the annular recess 6 that matches respectively on described two halves spherical shell (1,2) the oral area faying face.
Has the taper seat (7,8) that matches on the described two halves spherical shell oral area faying face respectively.
Beneficial effect: prior art make display shell blast lift-off tracks instability, and explosive effect is inhomogeneous because manufacture craft falls behind, and the spherical shell distortion is serious, and a little less than the joint strength, the spheroid distribution of weight is inhomogeneous.Through research experiment for many years, I develop a kind of particular manufacturing craft, adopt the produce once hull shape rule of moulding of environment-friendly materials, and the interface socket is tight, is convenient to be adhesively fixed.
1, adopts socket and bonding way location, make spherical shell each several part intensity even;
When 2, two hemispheres makes up the interface circumference can not take place and move inconsistent phenomenon, can fix without adhesive tape, get final product with the bonding interface of Instant cement, reduced clustered operation, saved artificial and time, eliminated the fire works display projectile shell distortion, other position intensity of interface intensity and spherical shell is more even;
3, through experiment showed, the employing the technical solution of the utility model, it is desirable more to open when quick-fried bright pearl moulding and effects,sound, display shell emission back good positioning effect.
