The utility model has the advantages that the upper mud layer can be effectively prevented from being broken under the protection of the buffering and protecting of the chaff filling layer and the homogeneous reinforced mud layer; the chaff filling layer also has the effects of stabilizing an effect medicine layer and a blasting medicine layer, and is beneficial to the safety of filling the upper mud layer; the building of reinforcing mud layer can bear bigger building pressure on the basis of ensuring safety, so that the structural strength of the reinforcing mud layer exceeds that of the upper mud layer.
Preferably, be equipped with second effect medicine layer between middle mud layer and the propellant powder layer, be equipped with between propellant powder layer and the second effect medicine layer and keep apart the circle scraps of paper, keep apart the center of circle scraps of paper and be equipped with the fire hole, ignition lead passes a fire and connects the propellant powder layer. After cylindricality display shell rose empty via the launching tube transmission, the high temperature gas that the propellant powder burnt formation was ignited the second effect powder layer from the hole of crossing a fire, the propellant powder has burnt totally this moment, cylindricality display shell is inertial flight in the air, the flight in-process, the high temperature high pressure gas that the second effect powder layer burnt formation is washed away and is kept apart the circle scraps of paper, wash out from the barrel bottom mouth after the propellant powder burning, long trail under the cloth of the flight path of cylindricality display shell in the air, trail terminal point links effects such as the general burst of cylindricality display shell and bouquet, brocade, realize that aerial compound effect shows.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is further described in detail with reference to the accompanying drawings and the detailed description.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Drawings
Fig. 1 is the internal structure schematic diagram of the cylindrical display shell of the present invention.
Detailed Description
Referring to the drawings, reflecting a specific structure of the present invention, the cylindrical display shell with the tail comprises a barrel 14, and a plastic cap 10 is arranged at the upper port of the barrel 1.
The inner cavity of the barrel body 14 is divided into an upper cavity and a lower cavity by a middle mud layer 5, the upper cavity device is provided with a mixed layer of explosive 6 and effect drug 7, the lower cavity device launches the drug layer 2, the upper end of the upper cavity is sealed by an upper mud layer 11, a reinforced mud layer 9 is filled at the upper end of the upper mud layer, the reinforced mud layer 9 and the upper mud layer 11 are both made of mud, and the homogeneous material arranged in a layered mode is favorable for fully protecting the upper mud layer 11. A chaff filling layer 8 is arranged at the lower end of the upper mud layer 11, namely between the effect medicine layer 7 and the upper mud layer 11, so as to stabilize the effect medicine layer 7 and the explosive layer 6, and simultaneously, the filling and building safety of the upper mud layer 11 is also facilitated in the actual production; meanwhile, the buffering and protecting functions of the chaff filling layer 8 ensure that the upper mud layer 11 is not easy to be impacted and broken.
During production, the middle mud layer 5 is built manually or by an oil press, the upper cavity device is provided with the explosive layer 6, the effect medicine layer 7 and the chaff filling layer 8, then the upper mud layer 11 is built manually to close the upper end opening of the cylinder body 11, and then the reinforced mud layer 9 is built, and the building of the reinforced mud layer 9 can bear larger building pressure (such as using the oil press) on the basis of ensuring safety, so that the structural strength of the reinforced mud layer 9 exceeds that of the upper mud layer 11.
The lower cavity of the barrel 14 is provided with a propellant charge layer 2, the lower end of the lower cavity is sealed by a circular paper sheet 1, and the upper cavity and the lower cavity are connected by a fire-passing lead 12 for fire transfer.
In this example, a second effective medicine layer 4 is arranged between the middle mud layer 5 and the propellant powder layer 2, an isolation circular paper sheet 3 is arranged between the propellant powder layer 2 and the second effective medicine layer 4, a fire passing hole 15 is arranged in the center of the isolation circular paper sheet 3, and an ignition lead 13 conducts fire and is connected with the propellant powder layer 2. During firing, the cylindrical display shell is placed into a launching tube (not shown in the figure), the ignition lead 13 is ignited to launch, high-temperature gas formed by burning the propellant powder layer 2 ignites the second effect propellant powder layer 4 from the fire passing hole 15, at the moment, the propellant powder layer 2 is burnt completely, high-temperature high-pressure gas formed by burning the second effect propellant powder layer 4 flushes the isolation circular paper sheet 3, flushes out from the bottom end opening of the tube body 14, and a long trail is arranged under the air along the flight path of the cylindrical display shell. The tail end point is connected with the explosion and the preset effect of the cylindrical display shell, wherein the explosion means that high-temperature and high-pressure gas formed by burning the second effect medicine layer 4 ignites the explosive layer 6 through the over-fire lead 12; the preset effect means that the explosive layer 6 ignites the effect explosive layer 7 to show preset aerial effects such as bouquets and brocade crowns, the structure arrangement enables the trail end point to naturally link the explosive and the preset effect, and the composite effect can be stably and reliably displayed in the night sky without other technical intervention (such as time delay lead wires).
The specific production process requirements of the cylindrical display shell are the same as those of the prior art. And will not be described in detail.
The foregoing embodiments are merely for clarity of explanation, and are not to be construed as limiting the present invention. The utility model discloses have known multiple substitution or warp in this technical field, do not deviating from the utility model discloses under the prerequisite of essence meaning, all fall into the utility model discloses a protection scope.
