Abstract
The invention discloses a display shell with a fixed launch direction and a fixed launch position. The bottom of the display shell is provided with three to eight tail fins corresponding to tail fin inserting slots, the upper portions of the tail fins are arranged by surrounding a propellant bag of the display shell, and the inner edges of the lower portions of the tail fins are integrally connected. A mounting inclined angle of the display shell is arranged corresponding to a display inclined angle. The structural strength and directing and positioning capacity of the tail fins are enhanced, so that the display shell is prevented from spinning in liftoff, explosion direction is fixed, and aerial pattern display angle can be guaranteed conveniently and reliably to meet enjoyment requirements. Further, the display shell is high in compatibility to existing display shell production process and convenient for linkage.
Description
Technical field
The present invention relates to the display shell that a kind of direction and location is launched.
Background technology
The structure of existing display shell is see Fig. 1, body is made up of episphere 1, lower semisphere 2, lower semisphere 2 bottom device passes fire lead-in wire 4 and launches cartridge bag 3, multiple bright pearl is embedded in the mixture opening dryness-fire medicine and filler of display shell inner chamber according to predetermined pattern arrangement, the arrangement surface of bright pearl is positioned at the faying face 5 of episphere 1 and lower semisphere 2, when display shell puts into launching gun barrel 6, faying face 5 is parallel with the plane at emission port 7 place of launching gun barrel 6, open quick-fried after the bright pearl of lighting form corresponding skydive picture.But be go up to the air in a rotative pattern during display shell ball-shooting, cause the angle of skydive picture and horizontal plane (ground) to be difficult to control, make the fireworks display performance spectators appreciating skydive on ground probably can't see best appreciation effect.
Fireworks display airborne installation empennage can make display shell go up to the air no longer in a rotative pattern, as the utility model patent " oriented launching fireworks " of Authorization Notice No. to be the utility model patent " a kind of display shell with directed empennage " of CN 2439011Y and Authorization Notice No. be CN 2442220Y.But these technical schemes are due to the structure existing problems of display shell and empennage thereof.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention, provides the display shell that a kind of direction and location is launched, and can realize the direction and location normal transmission being with empennage display shell, make the displaying angle of the aerial effect of display shell controlled, with satisfied appreciation requirement.In order to solve the problems of the technologies described above, the technical solution used in the present invention is, the display shell that a kind of direction and location is launched, it is characterized in that, the corresponding described empennage slot in bottom of described display shell is provided with 3-8 sheet empennage, each empennage top is launched cartridge bag around display shell and is arranged, and the medial margin of each empennage bottom connects as one.
In the present invention, according to the needs of firework display effect, the angle of skydive picture and horizontal plane (ground) is called displaying angle; Plane (or the plane at the upper end open place of described launching seat body at place bottom the faying face of the upper and lower hemisphere of display shell and body, or the plane at the emission port place of launching gun barrel) angle that formed is called installation angle, preferably, the installation angle correspondence of described display shell shows that angle is arranged.Make to show that angle meets and view and admire needs.
Preferably, described empennage bottom is rectangle or square.Especially described rectangle or foursquare outside inferior horn are rounded corners.
Improve as one, each empennage lateral border is connected by reinforcing ring.
Beneficial effect of the present invention is, adopts technique scheme, strengthens structural strength and the direction and location ability of empennage.No longer rotate when display shell is gone up to the air, open quick-fried direction and determine, guarantee that the displaying angle of aerial picture meets easily and reliably and appreciate requirement.Simultaneously high with existing display shell production technology compatibility, be connected convenient.
Described display shell is launched by launching gun barrel, and preferably, the launching gun barrel of described display shell is sleeved on launching seat, and launching seat comprises columniform base and body, and body is provided with 3-8 bar empennage slot; Described empennage slot distributes along the radius of body cross-section, all runs through body circumference at the radial and axial of body, and each empennage slot is uniformly distributed along body circumferencial direction; The inner chamber of body upper end is provided with propellant powder chamber, arranges the domatic of an arc transition between the opening of body upper end described in the opening of propellant powder chamber.
The cross section of described body can be the circle corresponding with base, and also can be the regular polygon that is circumscribed circle with described circle, the limit number of described regular polygon be identical with the number of described empennage slot.General when the specification of display shell is larger---as the specification of 8 inch or more, adopt just polygon body effectively can improve the stability of empennage.
Described launching seat and launching gun barrel can overall time shaping, but in order to install accurate convenience, preferred as one, described launching seat and launching gun barrel adopt dismountable combining structure.Preferred embodiment is further, and the base of described launching seat is provided with step and supports launching gun barrel bottom nozzle, and launching seat and launching gun barrel are provided with corresponding through hole and fix with bolt.In order to avoid emission cavity gunpowder exploded gas is leaked by empennage slot, the fit-up gap between launching seat and launching gun barrel, launching gun barrel bottom nozzle successively, described launching seat outer wall is provided with cannelure, device elastic seal ring in cannelure.Make described fit-up gap up.
The display shell being provided with corresponding empennage when setting off puts into launching gun barrel, and display shell empennage is inserted in completely in empennage slot and makes empennage protected; It is domatic and launch and accent ensure that launch pressure and height that spherical body is pressed in arc-shaped transition.
Improve as one, described launching seat chamber body domatic on be provided with some installing holes symmetrically, device spring in installing hole, the corresponding described position of mounting hole in described display shell bottom is provided with some assister bars, and assister bar to insert in described installing hole and compresses described spring.Its benefit is, the instant of detonation assister bar be inserted in installing hole helps to stablize body, strengthens directed during lift-off, and spring can also the lift-off of boosting body.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
