Oriented connecting rod device for rocket fireworks

Abstract

The invention discloses an oriented connecting rod device for rocket fireworks. The oriented connecting rod device for rocket fireworks is used for folding or unfolding of a connecting oriented rod. The oriented connecting rod device for rocket fireworks comprises a buckling fixing device (3), the buckling fixing device is a square groove, an upper fixing sleeve and the buckling fixing device areintegrated, a connecting boss (7) which is connected with a joint (2) is arranged on the right wall of a groove cavity of the portion, which is combined to the lower end of the upper fixing sleeve (1), of the buckling fixing device (3), inner buckle teeth (8) are arranged on inner cavity walls of two sides of the square groove of the buckling fixing device, a fixing device buckle hole (9) is further formed in the bottom of the square groove of the buckling fixing device, lower fixing sleeve buckle holes (5) which correspond to the inner buckle teeth (8) on the inner cavity walls of the buckling fixing device are arranged on the cavity walls of two sides of the lower fixing sleeve; and bottom buckle teeth (6) are further correspondingly arranged on the bottom surface of the lower fixing sleeve. The oriented connecting rod device for rocket fireworks is simple in structure, convenient and safe to operate, convenient to pack and transport and low in cost.

Description

technical field [0001] The invention relates to a fireworks display device, in particular to a directional connecting rod for rocket fireworks and a directional connecting rod device for rocket fireworks which is folded and shortened in length. Background technique [0002] In the prior art, rocket fireworks are composed of rocket fireworks body and a long wooden directional rod, and the size and length of the directional rod are determined by the size, weight and lift-off height of the rocket firework bomb, and generally The directional rod of the rocket firework is relatively long, and the finished product packaging requires a very long packing box, which makes storage and handling extremely inconvenient, and the cost is high, especially during transportation, because the packing box is long and heavy , resulting in loading and unloading difficulties and high transportation costs. Therefore, seeking a way to shorten the length of the rocket fireworks directional rod, whic...
