Description

Technical Field

[0001] This utility model relates to the field of directional launching technology for fireworks shells, specifically a directional positioning and launching device for fireworks shells. Background Technology

[0002] Firework launchers are widely used in various entertainment venues and gatherings to create a lively and entertaining atmosphere when hosting entertainment events such as weddings, parties, and celebrations. Firework shells are commonly used in the wedding industry. Firework shells are made of a large number of colored ribbons and are launched by a fireworks launcher.

[0003] In existing technology, fireworks shells need to be placed manually in a designated location before being launched upwards. However, there may be high-voltage lines or other flammable materials at the top, so the launch needs to be completed in a safe area. Traditional methods can fix the fireworks shells, but the launch angle can only be roughly determined.

[0004] During the research and development process, the applicant discovered a Chinese patent that discloses a "directional positioning and launching device for fireworks shells" (application number: 202220570032.5). This patent uses an angle adjustment mechanism at the bottom of the launcher to adjust the angle of the fireworks to be launched. However, this device still requires a rough judgment of the launch position during the angle adjustment process, and cannot achieve accurate directional control, thus failing to solve the problem of angle-oriented positioning and launching of traditional devices.

[0005] To address this issue, the applicant developed a targeted research and development project, designing a directional and positioning launching device for fireworks shells. This device specifically solves the problem that traditional angle adjustment methods still require a rough judgment of the launch position, making accurate directional control impossible. Utility Model Content

[0006] The purpose of this invention is to provide a directional and positioning launching device for fireworks shells to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A directional and positioning launching device for fireworks shells includes: a lower base, a supporting base plate above the lower base, a rotating seat fixedly connected to one top end of the supporting base plate, a cannon barrel rotatably connected to the inner side of the rotating seat, a threaded rod rotatably connected to one upper end of the supporting base plate, a threaded block threadedly connected to one side of the middle part of the threaded rod, a rotating frame rotatably connected to the top end of the threaded block, and the end of the rotating frame away from the threaded block rotatably engaging with the cannon barrel.

[0009] In one alternative: the lower base has an internal telescopic plate, and one end of the telescopic plate is fixedly connected to a fixing plate.

[0010] In one alternative: rubber pads are fixedly connected to the upper surface of the fixing plate and one side of the top center of the lower base, and convex blocks are fixedly connected to both ends of the bottom of the supporting base plate, with the convex blocks and the telescopic plate engaging through each other.

[0011] In one alternative: a convex hole is provided between the threaded block and the rotating frame, and a convex rod passes through the interior of the convex hole.

[0012] In one alternative: one end of the convex rod is a smooth round surface, and a counterweight is movably connected to the upper surface of the lower base away from the supporting base plate.

[0013] In one alternative: a knob is fixedly connected to one end of the threaded rod, and several buffer pads are fixedly connected to the bottom end of the lower base.

[0014] In one alternative: a laser emitter is fixedly connected to the upper end of the barrel, and a strip-shaped opening is provided on one side of the barrel.

[0015] In one alternative: an arc-shaped clamp is provided on one side of the inner side of the barrel, and an adjusting screw is rotatably connected to the middle of the outer side of the arc-shaped clamp, the adjusting screw being threadedly engaged with the barrel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a threaded rod, a threaded block, a rotating frame, and a cannon barrel. The rotation of the knob drives the threaded rod to rotate and engage with the threaded block, thus achieving threaded movement. This provides rotational support for the rotating frame, facilitating the lifting of the cannon barrel and completing the elevation angle adjustment. During the adjustment process, the laser emitter can emit laser light, which can assist in the accuracy of the subsequent fireworks launch position and complete directional adjustment control.

[0018] 2. This utility model uses a telescopic plate, a supporting base plate, a convex locking block, and a rotating frame. The telescopic plate can be stretched and retracted according to the length of the supporting base plate, reducing space occupation. The convex locking block can lock and fix the rotating frame after it reaches the supporting position, making it less likely to rotate. This structure enables the portable installation and disassembly of the launching device. Attached Figure Description

[0026] In one embodiment, such as Figure 1 As shown, the lower base 1 has a telescopic plate 3 inside. The lower base 1 is placed in the position to be used, and then pulled out by the telescopic plate 3 to extend to the required length. One end of the telescopic plate 3 is fixedly connected to a fixing plate 4.

[0027] In one embodiment, such as Figure 3 As shown, rubber pads 16 are fixedly connected to the upper surface of the fixed plate 4 and one side of the top center of the lower base 1. The rubber pads 16 can provide buffer support to prevent displacement caused by large impact forces. The rubber pads 16 can also increase the shock absorption effect. The bottom ends of the support base plate 2 are fixedly connected to convex blocks 17. The two convex blocks 17 are engaged with the telescopic plate 3 and the lower base 1 to complete the fixing function. The convex blocks 17 and the telescopic plate 3 are engaged through each other.

[0028] In one embodiment, such as Figure 2 As shown, a convex hole 13 is provided between the threaded block 12 and the rotating frame 6. A convex rod 14 passes through the inside of the convex hole 13. The convex rod 14 is inserted into the inside of the convex hole 13 to complete the locking and limiting, and is convexly locked with the rotating frame 6 to prevent angular rotation.

[0029] In one embodiment, such as Figure 1 As shown, one end of the convex rod 14 is a smooth round surface.

An adjusting screw 19 is rotatably connected to the middle of the outer side of the arc-shaped clamping plate 18. The firework tube will be sleeved inside the cannon barrel 7. Then, the adjusting screw 19 will rotate to move it against the arc-shaped clamping plate 18 and clamp it with the firework tube to achieve a fastening effect. The adjusting screw 19 and the cannon barrel 7 are threaded together.

[0033] The above embodiments disclose a directional positioning and launching device for fireworks shells. The working principle is as follows: During use, the entire structure is assembled. First, the lower base 1 is placed in the desired position. Then, the telescopic plate 3 is pulled out to the required length, and the supporting base plate 2 mates with the upper surface of the lower base 1. Two convex locking blocks 17 are then inserted into the telescopic plate 3 and the lower base 1 to achieve fixation. The cannon barrel 7 is installed inside the rotating seat 9 to achieve rotation. The two ends of the rotating frame 6 are respectively engaged with the threaded block 12 and the cannon barrel 7 to achieve rotational adjustment. After adjustment, the convex rod 14 is inserted into the convex hole 13 to achieve locking and limiting, locking the rotating frame 6 to prevent angle rotation. Finally, a counterweight 15 is pressed against the upper surface end of the cannon barrel 7 to buffer the impact force. The fireworks shell is then fitted inside the cannon barrel 7, and the adjusting screw 19 is rotated to move it against the arc-shaped clamping plate 18, clamping the fireworks shell for a secure hold.
