Description

Technical Field

[0001] This utility model relates to the field of fireworks launching technology, specifically a fireworks launching angle adjustment device. Background Technology

[0002] Fireworks are explosives set off on specific occasions, capable of displaying colorful, dazzling lights and patterns. They are typically composed of gunpowder and colorant, which, after being ignited, undergo a rapid chemical reaction to burn and explode, spraying the internal colorant into the air to create colorful sparks and patterns, adding a festive and joyful atmosphere to celebrations, entertainment, or special events.

[0003] Chinese patent CN217275832U discloses a fireworks launcher with a precisely adjustable angle. The fireworks launcher, through the setting of a slide, a fixed side plate, a launching component and a fixing component, enables the fireworks launcher to be adjusted in an easy and precise manner, thereby improving the ease of use of the fireworks launcher.

[0004] While the aforementioned patent enables adjustment of the fireworks launch angle, it is not convenient to adjust the launch direction. The entire launcher needs to be moved to adjust the launch direction, making it cumbersome and inflexible. Furthermore, the patent uses screws to fix the launch plate angle, which can easily loosen due to the reaction force generated when the fireworks are launched, resulting in the launch plate sliding and compromising safety.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-5This utility model provides a fireworks launch angle adjustment device, including a base 100, a housing 101 rotatably mounted on the upper surface of the base 100, and a fixing mechanism 200 between the base 100 and the housing 101. Arc-shaped slide rails 102 are provided on both sides of the housing 101, and arc-shaped sliding plates 103 are slidably mounted inside the arc-shaped slide rails 102. A top plate 104 is mounted on the top of both arc-shaped sliding plates 103, and a launcher 105 is provided on the upper surface of the top plate 104. An adjustment mechanism 300 capable of rotating the top plate 104 is provided inside the housing 101. Scale lines 107 are provided on the outer surface of the housing 101, and pointers 108 are provided on the outer surface of the arc-shaped sliding plates 103. A support column 106 is mounted on the bottom of the base 100.

[0027] In use, the support column 106 provides stable support for the base 100. When it is necessary to adjust the launch direction of the launcher 105, simply rotate the housing 101 horizontally to the appropriate angle, and then use the fixing mechanism 200 to fix it together with the base 100, thereby achieving the purpose of adjusting the launch direction. When it is necessary to adjust the launch angle of the launcher 105, since the arc-shaped slide rail 102 and the arc-shaped sliding plate 103 limit the top plate 104, the arc-shaped sliding plate 103 can be driven by the adjustment mechanism 300 to slide within the arc-shaped slide rail 102, thereby achieving the purpose of adjusting the vertical angle of the top plate 104. Moreover, the adjustment mechanism 300 has good self-locking properties, which can ensure the structural stability of the top plate 104 and prevent slippage during fireworks launch. It is safe and easy to operate.

[0028] Preferably, the fixing mechanism 200 includes a plurality of screw holes 201 coaxially formed on the upper surface of the base 100, a fixing block 202 is mounted on the outer surface of the housing 101, and a bolt 203 adapted to the screw holes 201 is installed inside the fixing block 202.

[0029] When it is necessary to adjust the firing direction of the transmitter 105, first unscrew the bolt 203 from the screw hole 201. At this time, the housing 101 is released from its fixation. Then, after rotating it to a suitable angle, screw the bolt 203 back into the screw hole 201 to achieve the purpose of adjusting the firing direction.

[0030] Preferably, the adjustment mechanism 300 includes a partial worm gear disk 301 mounted on the lower surface of the top plate 104, a rotating shaft 302 is rotatably mounted through the interior of the housing 101, a worm 303 is provided on the outer surface of the rotating shaft 302, and the worm 303 is meshed with the partial worm gear disk 301.

[0031] When it is necessary to adjust the launch angle of the launcher 105, the rotating shaft 302 can be turned. The rotating shaft 302 drives the worm gear 303 to rotate. Since the worm gear 303 meshes with the local worm wheel 301, and the arc-shaped slide rail 102 and arc-shaped sliding plate 103 limit the top plate 104, the local worm wheel 301 can be driven to rotate, thereby driving the top plate 104 to rotate, achieving the purpose of adjusting the launch angle. In addition, the local worm wheel 301 and the worm gear 303 have good self-locking properties, which can ensure the stability of the top plate 104 during the fireworks launch process, avoid slippage, and ensure high safety.

[0032] Preferably, a cross-shaped plate 400 is provided at the bottom of the base 100, and universal wheels 401 are installed at the four corners of the lower surface of the cross-shaped plate 400. An internally threaded sleeve 402 is installed on the upper surface of the cross-shaped plate 400, and a screw 403 is rotatably installed on the lower surface of the base 100. The screw 403 is inserted into the internally threaded sleeve 402 and threadedly connected to it.

[0033] Through the threaded connection between the screw 403 and the internal threaded sleeve 402, when the screw 403 is rotated, the cross-shaped plate 400 can be driven down, so that the four casters 401 support the ground, thus making it easy to move the device without manual handling. It is flexible to use. When fireworks need to be launched, the casters 401 can be raised so that the support column 106 supports the ground.

[0034] Preferably, a telescopic rod 500 is connected to the lower surface of the base 100, and the end of the telescopic rod 500 is connected to the upper surface of the cross-shaped plate 400.

[0035] The telescopic rod 500 serves as a limit for the cross-shaped plate 400, preventing it from rotating and ensuring its smooth lifting and lowering.

[0036] Preferably, a handwheel 600 is mounted on the outer surface of the screw 403, and a rubber pad is provided on the outer surface of the handwheel 600.

[0037] The screw 403 can be rotated easily and effortlessly thanks to the handwheel 600.

[0038] Preferably, a support block 700 is installed inside the housing 101, and the end of the rotating shaft 302 is rotatably connected to the support block 700.

[0039] The support block 700 provides a support point for the end of the rotating shaft 302, making it more stable and smooth during rotation, and ensuring the meshing state of the worm 303 and the local worm wheel disk 301.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
