Technical Field
[0001] This utility model belongs to the technical field of fireworks display equipment, and in particular relates to a display system. Background Technology
[0002] Small fireworks are often set off at the opening ceremonies of large ceremonies, performances, or sporting events. While many existing small fireworks launching devices can adjust the launching angle to meet various needs, most of these devices are single slides without tilt angle indicators. When fixing the cannon after adjusting the angle in the slide, most of them use two points to form a line for fixation, resulting in poor stability.
[0003] For example, a Chinese patent entitled "Fireworks Launching Cannon Barrel Fixing Device and its Launching System and Launching Method" (application publication number CN111473694 A) states that: the rotating seat (22) is provided with a swing guide groove (222) along the swing trajectory of the cannon shaft (21), the swing guide groove (222) is an arc guide groove centered on the pin shaft (221), and the locking component between the cannon shaft (21) and the rotating seat (22) is a cannon shaft locking screw (212) that tightens the cannon shaft (21) at any position of the swing guide groove (222). For example, a Chinese patent entitled "A Fireworks Display Device" (authorization announcement number CN 216815197 U) describes: The placement tube (4) includes a tube body (9), the tail end of the tube body (9) is rotatably connected to the connecting seat (5), the front end of the tube body (9) passes through the guide groove (8), and the tube body (9) is slidably connected to the guide groove (8), the side wall of the tube body (9) is symmetrically fixedly connected with a first stud (15), the first stud (15) passes through the arc-shaped hole (7), the first stud (15) is threadedly connected to a first fixing sleeve (11) at one end outside the arc-shaped guide plate (6), the tube body (9) is symmetrically provided with strip-shaped holes (10), the tube body (9) is slidably connected with a base (13), the side wall of the base (13) passes through the strip-shaped hole (10) and is threadedly connected with a second fixing sleeve (14).
[0004] In addition, most existing small fireworks display devices are open-type. During the installation of small fireworks, they may accidentally burn and explode due to various reasons. When small fireworks accidentally burn and explode, the hazard distance of open-type display devices is relatively far, and the hazard is relatively large.
[0005] Therefore, there is a need for a ignition device that can adjust the ignition angle, and that can be more stable after the angle is adjusted, reduce changes in the ignition angle, and is safer to use. Utility Model Content

All firing devices are mounted on a single launcher 6, and at least one launcher 2 is installed inside the chamber body 6.
[0030] This utility model provides embodiments of two box-shaped bases 11: In Example 1, the base 11 of the enclosure is a support consisting of multiple horizontal and vertical bars, and the enclosure 6 is fixed to the base 11. Shock-absorbing devices 12 are installed at the bottom of the support, and multiple sets of shock-absorbing devices 12 are configured.

[0032] The ignition device in this invention is installed inside the ignition box and used as a whole ignition system, which makes it safer to use. Alternatively, the launcher 4 in the ignition device can be fixed and the ignition device can be used alone.
[0033] When used as a firing system, multiple firing devices are installed inside the firing box. The two sides of the launcher 4 are connected to the inner sidewalls of the box body 6. The multiple firing devices are arranged in at least one row. In this embodiment, two rows of firing devices are placed in opposite directions inside the firing box, with the indicator component 5 facing inward and the tube clamp 2 and the launch tube 1 facing outward. The size of the launch tube 1 and the tube clamp 2 can be replaced according to actual needs.
[0034] Each ignition device placed in the ignition box can be installed individually on the inner wall of the box 6, or they can share a launcher 4. When the launcher 4 is shared, multiple sets of upper chucks 4-2, lower chucks 4-3, and rotating holes 4-1 are provided on the launcher 4 to install multiple sets of pipe clamps 2 and launch tubes 1 on the same launcher 4. In this embodiment, a single launcher 4 with a plate structure is used, with the two sides of the plate connected to the inner wall of the box 6.
[0035] The plate can be welded to the inner wall of the metal box 6 using connectors, or it can be movably connected to the inner wall of the metal or other material box 6 using connectors.
[0036] After the ignition device is installed, the angle of the launching tube 1 is adjusted using the connecting component 15. After adjustment, it is fixed, the flammable material is placed, the box cover 7 is fastened, and the wiring of the flammable material is connected and tested. When ignition is required, the box cover 7 is opened to ignite the flammable material. A power distribution box component 14 is also installed outside the box body 6. For ease of operation, the side of the box cover 7 is provided with an opening and closing grip 9. The outer side of the box body 6 is provided with operating parts 13 for adjusting the position and angle of the ignition box and for pulling up the ignition box.
[0037] When the ignition device is used alone, different sizes of launch tubes 1 can be selected according to actual needs, along with corresponding sizes of tube clamps 2. First, the launch tube 1 and tube clamp 2 are installed. Then, the tube clamp 2 is movably mounted on the upper chuck 4-2, lower chuck 4-3, and rotating hole 4-1 via the connecting assembly 15. This allows the connecting assembly 15 to slide within the upper chuck 4-2 and lower chuck 4-3, using the rotating hole 4-1 as the axis, thereby moving the tube clamp 2 and adjusting the angle of the launch tube 1 left or right. An indicator component 5 is installed at the end of the connecting assembly 15 furthest from the tube clamp 2, allowing for a direct visual display of the angle value during adjustment, thus meeting the specific launch angle requirements.
[0038] Individual ignition devices can also be installed on the ignition base plate according to usage requirements. They can be arranged into different graphics, text, and patterns based on various designs. A freely rotating turntable can also be installed at the bottom of the base plate to meet the ignition device's angle requirements in multiple dimensions. After adjusting the angle of launch tube 1, the ignition material is installed and ignited.
[0039] During the adjustment of the launch tube 1, the tube clamp 2 on the upper part of the launch tube 1 slides in the upper chuck 4-2 and lower chuck 4-3 with the rotating hole 4-1 as the axis via the connecting assembly 15, thereby adjusting the angle. When fixing is required, the fastener at the end of the connecting assembly 15 is tightened to fix the tube clamp 2 in the upper chuck 4-2, lower chuck 4-3, and rotating hole 4-1. The connecting assembly 15 is an adjustable connector. In this embodiment, bolts and nuts are used. There are two sets of connectors in the upper chuck 4-2, and the lower chuck 4-3 is divided into left and right chucks, each with a set of connectors. Thus, the two sets of connectors in the upper chuck 4-2, the left and right connectors in the lower chuck 4-3, and the connectors in the rotating hole 2-3 form a multi-point fixation for the tube clamp 2 and the launch tube 1 it clamps, making it more stable and reducing angular deviation during the launch process.
[0040] This utility model has a simple and reasonable structure. The pipe clamp 2 can be flexibly adjusted to display the tilt angle. When fixed, it is fixed at multiple points to reduce the deviation generated during ignition. The ignition box can reduce the harm caused by accidental combustion and explosion, improve the sense of security of ignition, and reduce accidental injury to the operator.
