Description

Technical Field

[0001] This utility model relates to the technical field of fireworks launching devices, specifically an angle-adjustable fireworks launching device. Background Technology

[0002] Fireworks are launched through a launch tube. Before launch, the fireworks body must be accurately installed into the launch tube to ensure that the body fits snugly against the tube wall to ensure launch stability. During launch, the propellant at the bottom of the fireworks is ignited by an ignition device. The high-pressure gas generated by the combustion of the propellant propels the fireworks upward at high speed along the inner wall of the launch tube until it bursts out of the tube and explodes in the air.

[0003] For example, the patent with authorization announcement number CN217465532U describes an angle-adjustable fireworks launcher. By installing a fixing bolt on the angle adjustment slider and fixing a connecting nut on the angle adjustment slider, the fixing bolt and the connecting nut are threaded together. Tightening the fixing bolt so that it is pressed against the adjustment crossbar can achieve positioning and fixation, thereby keeping the grid frame at a specific angle position. At the same time, the angle of the grid frame can be changed by moving the angle adjustment slider. This adjustment method can be adjusted arbitrarily according to actual use needs, thereby matching different fireworks shapes.

[0004] The existing technology has the following problems:

[0005] In the existing technology, when the angle adjustment slider is fixed by the connecting nut, the connecting nut must be loosened to release the limit on the angle adjustment slider every time the grid frame angle is adjusted. After the slider moves to the target position, the connecting nut must be tightened again to complete the fixation. The whole adjustment process requires frequent disassembly and installation of the nut. The operation steps are repetitive and time-consuming, which not only increases the operation burden of the staff, but also leads to low angle adjustment efficiency and is more troublesome to use.

[0006] Based on this, an angle-adjustable fireworks launcher is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0007] The purpose of this invention is to provide an angle-adjustable fireworks launcher to solve the problems in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0017] In one alternative: the surface of the launch tube is provided with a groove for placing the lead wire.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses an adjusting seat and a fixing block to assist in adjusting the angle of the support plate, thereby adjusting the launch angle of the firework shell. The adjusting groove provides sliding space for the sliding rod. Pressing the pressure plate can drive the sliding rod to move. The rotating shaft is used to lock the angle of the support plate. The locking block can limit the rotation shaft when it is engaged with the fixing block. The first spring can drive the pressure plate to reset, thereby causing the sliding rod to drive the locking block to engage with the fixing block, ultimately achieving the limitation of the angle of the support plate and completing the adjustment of the launch angle of the firework shell.

[0020] 2. This utility model provides conditions for the movement of the transmission plate through the slide rail. The movement of the transmission plate along the slide rail can drive the insert block to engage with the limiting seat, thereby limiting the closing block and providing conditions for locking or unlocking the closing block. At the same time, the cooperation between the rotating seat and the rotating block provides conditions for the rotation of the closing block. After the fireworks shells are fired, rotating the closing block can open the launch tube, making it easy to remove the remaining fireworks shell shells inside the launch tube, which provides convenience for subsequent launch operations.
