Description

Technical Field

[0001] This invention belongs to the technical field of fireworks display equipment, and in particular relates to a display device, a display box and its usage method. 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. Summary of the Invention

[0006] To address the problems in existing technologies, such as insufficient stability of the barrel fixing, easy angle deviation during firing, inability to display the tilt angle, and the open barrel setting leading to a long hazard distance and greater danger in case of accidental combustion and explosion, a firing device, firing box, and method of use are provided. These devices can be stably fixed, can display the tilt angle, and reduce the hazards caused by accidental combustion and explosion.

[0029] The specific steps for using a fireworks display box are as follows: S1: Install the launcher 4 inside the firing box, and install the tube clamp 2 and the launch tube 1; S2: Adjust the angle of each launch tube 1 on the launcher 4. The indicator component 5 displays the adjustment angle. After adjustment, fix the tube clamp 2. S3: Place the incendiary material into launch tube 1; S4: Check the wiring connected to the flammable material; S5: Open the lid when it is time to set off the fireworks.

[0030] In step S1, the launching tube 1 is replaced according to actual needs, and different launching tubes are matched with corresponding tube clamps 2.

[0031] This invention provides an embodiment of two housing 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. A shock-absorbing device 12 is installed at the bottom of the support, and a set of shock-absorbing devices 12 is provided. Each shock-absorbing device 12 has at least one shock-absorbing block 12-1. In this application, each shock-absorbing device 12 has two shock-absorbing blocks 12-1, one on the left and one on the right. In practical use, counterweights are added to the horizontal and vertical bars for fixation, making the ignition box more stable and reducing the risk of accidental explosion.

[0032] In embodiment 2, the base 11 of the container is located at the lower part of the four corners of the container 6, and includes a support part connecting the container 6 and a shock-absorbing device 12 below the support part. In this application, one shock-absorbing device 12 is set under each support part. In actual use, the container 6 is reinforced by adding counterweights to the bottom of the container 6, making the ignition box more stable and reducing the damage from accidental combustion and explosion.

[0033] When in use, the launcher 4 in the ignition device is fixed, and the ignition device can be used alone or placed in the ignition box for safe ignition, thus improving safety during use.

[0034] 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 at the lower part of the launch tube 1 is movably mounted on the rotating hole 4-1 via the second connecting assembly 16. The first connecting assembly 15 and the third connecting assembly 17 movably mount the tube clamp 2 on the upper chuck 4-2 and the lower chuck 4-3, respectively. By rotating the second connecting assembly 16 within the rotating hole 4-1, the first connecting assembly 15 and the third connecting assembly 17, with the rotating hole 4-1 as the axis, move the tube clamp 2, thereby adjusting the angle of the launch tube 1 left and right. An indicator assembly 5 is installed at the end of the second connecting assembly 16 and the third connecting assembly 17 furthest from the tube clamp 2. This allows for a direct visual display of the angle value during adjustment, thus meeting the specific launch angle requirements. In this invention, the angle adjustment value of the launch tube 1 is -40° to 40°. After adjusting the angle of the launch tube, install the flammable material and launch it.

[0035] Individual ignition devices can also be installed on the ignition base plate according to usage requirements, and arranged into different graphics, texts, and patterns according to different 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 more dimensions.

[0036] When the ignition device is placed inside the ignition box, multiple sets of ignition devices are set up. The two sides of the launcher 4 are connected to the inner sidewall of the box 6. The multiple sets of ignition devices are set up in at least one row. In this embodiment, two rows of ignition devices are placed in the ignition 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.

[0037] 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.

[0038] 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.

[0039] After the ignition device is installed, the angle of the launching tube 1 is adjusted by the first connecting component 15, the second connecting component 16, and the third connecting component 17. After adjustment, it is fixed, the ignition material is placed, the box cover 7 is fastened, the ignition material circuit is connected and tested, and when it is time to ignite, the box cover 7 is opened to ignite.

[0040] During the adjustment of the launch tube 1, the upper tube clamp 2 of the launch tube 1 slides in the upper chuck 14-2 via the first connecting component 15, while the lower tube clamp 2 of the launch tube 1 slides in the lower chuck 4-3 via the second connecting component 16, thereby adjusting the angle. When fixing is required, the fasteners at the ends of the first connecting component 15, the second connecting component 16, and the third connecting component 17 are tightened to fix the tube clamp 2 in the upper chuck 4-2, the lower chuck 4-3, and the rotating hole 4-1. The connecting components are multiple sets of adjustable connecting parts. In this embodiment, bolts and nuts are used. There are two sets of connecting parts in the upper chuck 4-2, and the lower chuck 4-3 is divided into left and right chucks, each with a set of connecting parts. In this way, the two sets of connecting parts in the upper chuck, the left and right connecting parts in the lower chuck, and the connecting parts in the rotating hole 4-1 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. An electrical distribution box assembly 14 is also provided outside the box body 6. To facilitate operation, an opening and closing gripping part 9 is provided on the side of the box cover 7. An operating part 13 is provided on the outer side of the box body 6 for adjusting the position and angle of the ignition box and for pulling up the ignition box.

[0041] The invention has a simple and reasonable structure. The pipe clamp 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.
