Abstract
The utility model discloses an emission cylinder with controllable chamber pressure, which includes an emission upper cylinder (1) and an emission lower cylinder (2), wherein a lower end of the emission upper cylinder is connected to an upper end of the emission lower cylinder, the emission lower cylinder is provided with a setting off chamber (7), a hole connected to an ignition head (5) is arranged on a side surface of the lower end of the emission cylinders, the ignition head is provided with an ignition hole (8) directly communicated with the setting off chamber, and an ignition harness can be inserted in the ignition hole. The emission cylinder with controllable chamber pressure can control the fixed point height of an emission track of the fireworks set off in the air, and continuously repeat and use for many times with low cost and high security.
Description
Technical field
The utility model relates to a kind of launching tube of fireworks, particularly a kind of controlled gun pressure launching tube of highly setting off for the aerial fixed point of fireworks.
Background technology
Usually want to express the fine wish of heart and blessing by a kind of specific mode welcoming feria period of the day from 11 p.m. to 1 a.m people, and set off fireworks be express in this mode modal a kind of, not only set off fireworks and to bring strong atmosphere to people, and can also give full expression to people's emotion in the heart, therefore, can express this emotion no more than setting off the fireworks of subtitle graphic aloft, at present, though appeared at the fireworks that represent subtitle graphic in the air, but they can not control the gun pressure of firework launching, reach fixed point and highly set off thereby can not control track, can't realize preferably that subtitle graphic is to represent effect.
The utility model content
The problem that the utility model exists for above-mentioned prior art, it is a kind of not only simple in structure that the utility model provides, and can control the fixed point height that fireworks are seted off launching track aloft, can also constantly repeatedly use, production cost is low, safe controlled gun pressure launching tube.
The technical scheme that its technical problem that solves the utility model adopts is: described controlled gun pressure launching tube comprises emission top cylinder and emission doffing, emission top cylinder lower end links to each other with emission doffing upper end, be provided with in the described emission doffing and set off the chamber, have the hole that is connected with match board head on the described launching tube lower end side, have vent in the described match board head and directly communicate with setting off the chamber, described vent can insert fuse.
In order to control the gun pressure of firework launching, reach fixed point and highly set off thereby can control track, produce the effect of institute's hope, therefore, be provided with seal and constant voltage sheet in emission top cylinder lower end with the interface that the launching tube upper end links to each other.
Characteristics of the present utility model are can bring strong happy atmosphere to people in the celebrating date, can control the launching track that fireworks set off and express people's hope in the heart with the subtitle graphic that the height and position that reaches appointment shows different-effect in space, it can not only constantly repeatedly use, also can utilize electronic ignition mode to set off fireworks, so that safe.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1, emission top cylinder, 2, the emission doffing, 3, the constant voltage sheet, 4, seal, 5, match board head, 6, effect tube, 7, set off the chamber, 8, vent.
The specific embodiment
In Fig. 1, described controlled gun pressure launching tube comprises emission top cylinder 1 and emission doffing 2, described emission top cylinder becomes cylindrical or square with the emission doffing, emission sleeve lower end is provided with the connecting hole corresponding with the launching tube upper end, arrange in the described emission doffing and set off chamber 7, described setting off is equipped with ignition charge in the chamber, and have the hole that is connected with match board head 5 on the emission doffing lower end side, have in the described match board head vent 8 directly with set off the chamber and communicate, described vent can insert fuse and the straight-through ignition charge of setting off in the chamber, described fuse can be electronic ignition line or lead-in wire, can fix a point highly to set off in order to make the skyborne launching track of setting off fireworks, produce the better effects if of institute's hope, therefore, be provided with seal 4 and constant voltage sheet 3 in emission top cylinder lower end with the interface that the launching tube upper end links to each other, described seal can be the O RunddichtringO, described constant voltage sheet becomes cylindrical or square, described constant voltage sector-meeting makes the emission doffing set off the chamber and produces a certain size pressure, so just so that set off the big or small counter-pressure of chamber generation when burning so that the constant voltage sheet is broken, thereby allowing the effect tube 6 that is contained in constant voltage sheet top be transmitted into required height sets off, therefore, when realizing this firework display effect, needs just can constantly reuse controlled gun pressure launching tube.
Claims (2)
1. controlled gun pressure launching tube, it is characterized in that: it comprises emission top cylinder (1) and emission doffing (2), emission top cylinder lower end links to each other with emission doffing upper end, be provided with in the described emission doffing and set off chamber (7), have the hole that is connected with match board head (5) on the described launching tube lower end side, have vent (8) in the described match board head and directly communicate with setting off the chamber, described vent can insert fuse.
