Description

Technical Field

[0001] This utility model relates to the field of confetti technology, and in particular to a multi-unit confetti synchronous launcher. Background Technology

[0002] In various celebratory occasions such as weddings, business openings, and festival celebrations, confetti cannons serve as a core prop for creating atmosphere. Their launch effect directly impacts the visual presentation and atmosphere of the event. With the expansion of event scale and the increasing demands for a sense of ceremony, the method of launching single confetti cannons one by one can no longer meet the visual needs of "centralized, large-scale, and synchronized" presentation. This has led to the research and development and application of multi-unit confetti cannon synchronous launchers. With "multiple launch channels + synchronous triggering" as its core design goal, this device achieves the simultaneous launch of multiple confetti cannons through an integrated mechanical structure and control system. It can create a dense spray effect of ribbons and confetti in a short time, effectively enhancing the festive atmosphere and visual impact of celebrations. It has become one of the indispensable key pieces of equipment in modern celebrations and is widely used in diverse scenarios such as small family parties, large-scale commercial ceremonies, and public festival gatherings.

[0003] Existing multi-launcher confetti launchers typically use an integrated metal frame or folding metal bracket as a base. The bottom of the frame is equipped with fixed anti-slip pads or adjustable support legs to increase the contact area and friction with the ground, ensuring the overall stability of the device during launch. In terms of launch structure, they mostly use arrayed fixed-specification launch tubes. The launch tubes are mostly hollow cylindrical structures made of metal or high-strength plastic. The thickness of the tube wall and the inner diameter are designed according to the size of the specific confetti model. There are no additional clamping components inside the tube; the initial positioning of the confetti is achieved only through the gap fit between the tube wall and the outer shell of the confetti. Synchronous triggering technology is mainly divided into two categories: electronic triggering and mechanical linkage. Electronic triggering uses a controller to synchronously supply power to the resistance wire or electronic ignition module at the bottom of each launch tube. The resistance wire heats up and melts the confetti binding wire or triggers the gas generation component to achieve synchronous launch. Mechanical linkage uses mechanical structures such as linkages, gears, or cables to connect the triggering components of each launch tube.

[0004] Existing multi-unit confetti launchers use a "fixed-size design" for their launch tubes, whose inner diameter is only compatible with a single model or a very small range of confetti sizes. When users need to use confetti with smaller or larger outer diameters, if a small-sized confetti is inserted, the gap between the tube wall and the confetti will be too large, causing the confetti to wobble inside the tube. This can easily lead to problems such as trajectory deviation, tube jamming, or premature detachment during launch. If a large-sized confetti is forcibly inserted, the size mismatch will prevent the confetti from being fully inserted into the launch tube, or even damage the confetti shell, making normal launch impossible. This single-size-fits-all design greatly limits the flexibility of the launcher. Users need to purchase separate launchers for different sizes of confetti, which not only increases the cost of use but also reduces the equipment's adaptability to different scenarios, making it difficult to meet the needs of diverse celebrations for different sizes of confetti. Therefore, a multi-unit confetti launcher is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-unit confetti launcher, which aims to improve the problems of existing multi-unit confetti launchers that are only suitable for single or very small range of confetti sizes due to the fixed specification design of the launch tubes, resulting in low flexibility of use, increased cost due to the need to purchase additional equipment, and weak scene adaptability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-unit confetti launcher includes a launcher, an interface inside the launcher, and multiple launch tubes inside the launcher, each launch tube containing a positioning component.

[0008] The positioning assembly includes symmetrical support frames, each support frame having one side fixedly connected to the side wall of the launch tube. Each support frame has a sliding rod slidably connected inside, and each sliding rod has an anti-slip groove inside. One end of each sliding rod is fixedly connected to a limit ring, and each limit ring is slidably connected inside the support frame. One side of each limit ring is provided with symmetrical springs, one end of each spring being fixedly connected to the side wall of the limit ring, and the other end of each spring being fixedly connected to the inner wall of the support frame. Multiple support components are provided on the outer wall of the launch frame.

[0009] As a further description of the above technical solution:

[0010] Each of the support components includes a connecting plate and mounting bolts. Each connecting plate is disposed on the side wall of the launcher, and each mounting bolt is slidably connected inside the connecting plate. The mounting bolts pass through the connecting plate and are threadedly connected to the launcher.

[0011] As a further description of the above technical solution:

[0012] Each of the connecting plates is fixedly connected to a support column on one side, and each support column is slidably connected to a connecting shaft on its outer wall.

[0013] As a further description of the above technical solution:

[0014] Each of the connecting shafts has a support shaft slidably connected to its outer wall, and each of the support columns has a spring sleeved on its outer wall.

[0015] As a further description of the above technical solution:

[0016] One end of each of the two springs is fixedly connected to the side wall of the connecting plate, and the other end of each of the two springs is fixedly connected to the side wall of the connecting shaft.

[0017] As a further description of the above technical solution:

[0018] Each of the support shafts is fixedly connected to a positioning column inside, and a support plate is fixedly connected to the bottom of each support shaft.

[0019] As a further description of the above technical solution:

[0020] Each of the connecting shafts is fitted with a spring three on its outer wall. One end of each spring three is fixedly connected to the top of the support shaft, and the other end of each spring three is fixedly connected to the outer wall of the connecting shaft.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the limiting ring is driven to move by pulling the sliding rod, and then the confetti is inserted into the launch tube. The elastic restoring force of the spring pushes the limiting ring to contact the outer wall of the confetti, thereby achieving the effect of limiting the confetti of different sizes. This solves the problem that the existing launcher is only suitable for a single size of confetti due to the fixed specification design of the launch tube, resulting in low flexibility of use and the need to purchase additional equipment. It improves the efficiency of the launcher in adapting to diverse confetti specifications.

[0023] 2. In this utility model, the sliding compression spring 2 of the support column, and the sliding compression of the connecting shaft and the spring 3 work together to achieve the effect of elastic support, which solves the problem of unstable support when the existing launcher is placed on uneven ground and improves the adaptability of the launcher in complex sites.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a multi-unit confetti launcher, including a launcher 1. The launcher 1 has an interface 2 inside. The launcher 1 has a frame structure and has a reserved interface 2 for connecting to an external control system. The interface 2 can realize the transmission of control signals and power, providing conditions for subsequent synchronous launch. The launcher 1 has multiple launch tubes 3 inside. The multiple launch tubes 3 are arranged in parallel and have the same axial direction to ensure that the spray direction of the confetti is uniform during launch. Each launch tube 3 has a trigger component inside. The launch command issued by the control device is synchronously transmitted to the trigger component at the bottom of each launch tube 3. The trigger component is a synchronously powered resistance wire or ignition module, so that the confetti in all launch tubes 3 can be ignited at the same time. This is the prior art and will not be described in detail. Each launch tube 3 has a positioning component inside for positioning and fixing the confetti.

[0033] The positioning component includes symmetrical support frames 4, each support frame 4 having a "U"-shaped plate structure. One side of each support frame 4 is fixedly connected to the inner wall of the launch tube 3 by welding, and the openings of the two support frames 4 are opposite to each other, forming a clamping space for the confetti. One side of each support frame 4 is fixedly connected to the side wall of the launch tube 3. Each support frame 4 has a sliding rod 5 slidably connected inside, and each sliding rod 5 has an anti-slip groove 8 inside. Each support frame 4 has a sliding channel that matches the sliding rod 5, and the sliding rod 5 can slide horizontally inside the support frame 4 along the channel. The anti-slip groove 8 has a strip-shaped concave structure and is set along the length of the sliding rod 5, which can increase the friction between the user and the sliding rod 5.

[0034] Each sliding rod 5 is fixedly connected to one end with a limiting ring 6. The limiting ring 6 has a circular ring structure, and its outer diameter is slightly smaller than the inner diameter of the sliding channel inside the support frame 4. Each limiting ring 6 is slidably connected inside the support frame 4 and can move together with the sliding rod 5 in the channel. Each limiting ring 6 is slidably connected inside the support frame 4. A symmetrical spring 7 is provided on one side of the limiting ring 6. When each spring 7 is in its naturally extended state, it can push the limiting ring 6 to move the sliding rod 5 towards the center of the launch tube 3. One end of each spring is fixedly connected to the side wall of the limiting ring 6 by welding, and the other end of each spring 7 is fixedly connected to the inner wall of the support frame 4 by welding. When the confetti is loaded into the launch tube 3, it will squeeze the sliding rods 5 on both sides, causing the spring 7 to compress and generate a reverse elastic force, thereby forming an elastic clamping and positioning of the confetti through the sliding rods 5. One end of each spring 7 is fixedly connected to the side wall of the limiting ring 6, and the other end of each spring 7 is fixedly connected to the inner wall of the support frame 4. The outer wall of the launch frame 1 is provided with multiple support components to enhance the overall stability.

[0035] Reference Figure 3 - Figure 5 Each support component includes a connecting plate 9 and mounting bolts 10. Each connecting plate 9 is a rectangular plate structure, fitted to the side wall of the launcher 1. The connecting plate 9 has through holes adapted to the mounting bolts 10. Each mounting bolt 10 is slidably connected to the inside of the connecting plate 9 through the through holes. The threaded part of the mounting bolt 10 passes through the connecting plate 9 and is threadedly connected to the threaded hole pre-set on the side wall of the launcher 1. By tightening the mounting bolts 10, the connecting plate 9 can be firmly fixed to the launcher 1, which facilitates the disassembly and maintenance of the support components. Each connecting plate 9 is set on the side wall of the launcher 1. Each mounting bolt 10 is slidably connected to the inside of the connecting plate 9. The mounting bolt 10 passes through the connecting plate 9 and is threadedly connected to the launcher 1. Each connecting plate 9 has a support column 11 fixedly connected to one side. The support column 11 is cylindrical and set perpendicular to the connecting plate 9.

[0036] Each support column 11 has a connecting shaft 12 slidably connected to its outer wall. The connecting shaft 12 is a hollow tubular structure with an inner diameter that matches the outer diameter of the support column 11. It can slide along the axial direction of the support column 11. Each connecting shaft 12 has a supporting shaft 14 slidably connected to its outer wall. The supporting shaft 14 is also a hollow tubular structure with an inner diameter slightly larger than the outer diameter of the connecting shaft 12, allowing the connecting shaft 12 to slide inside the supporting shaft 14, forming a telescopic support structure. Each support column 11 has a spring 13 sleeved on its outer wall. The spring 13 is located between the support column 11 and the connecting shaft 12. One end of each spring 13 is fixedly connected to the side wall of the connecting plate 9 by welding. The other end of each spring 13 is fixedly connected to the side wall of the connecting shaft 12 near the connecting plate 9 by welding. When the connecting shaft 12 slides along the support column 11, the spring 13 can generate an elastic buffer force to offset part of the launch recoil force.

[0037] One end of each spring 13 is fixedly connected to the side wall of the connecting plate 9, and the other end of each spring 13 is fixedly connected to the side wall of the connecting shaft 12. A positioning post 16 is fixedly connected inside each support shaft 14, and a support plate 15 is fixedly connected to the bottom of each support shaft 14. The support plate 15 has a circular or rectangular plate structure, and its area is larger than the cross-sectional area of ​​the support shaft 14, which increases the contact area with the ground and improves support stability. A spring 17 is sleeved on the outer wall of each connecting shaft 12. The spring 17 is located on the connecting shaft 12. Between 2 and support shaft 14, one end of each spring 3 17 is fixedly connected to the top of support shaft 14 by welding, and the other end of each spring 3 17 is fixedly connected to the outer wall of the connecting shaft 12 away from the connecting plate 9 by welding. Together with spring 2 13, they form a double elastic buffer, further enhancing the support assembly's ability to absorb launch recoil force and ensuring the overall stability of launch frame 1. One end of each spring 3 17 is fixedly connected to the top of support shaft 14, and the other end of each spring 3 17 is fixedly connected to the outer wall of connecting shaft 12.

[0038] Working Principle: When using this multi-unit synchronized confetti launcher, the operator first places the confetti into the launch tube 3. The interface 2 allows the operator to easily connect to control equipment. The external control equipment issues a launch command, which is synchronously transmitted to the trigger components at the bottom of each launch tube 3 to initiate the launch. When different sized confetti need to be placed, the operator inserts their finger into the anti-slip groove 8 and pulls the sliding rod 5. This pulling force causes the limiting ring 6 to move inwards towards the support frame 4, compressing the spring 7 and causing it to elastically deform. Then, the confetti is placed... Inside the launch tube 3, the force pulling the sliding rod 5 is released. The elastic restoring force of spring 7 pushes the limiting ring 6 to contact the outer wall of the confetti cannon, thus limiting the different confetti cannons. During the confetti cannon's firing, an impact force will be generated. The support column 11 slides inside the connecting shaft 12, compressing the spring 13 to absorb and buffer the lateral impact force. The connecting shaft 12 slides inside the support shaft 14, compressing the spring 17 to absorb and buffer the longitudinal impact force, thereby achieving the effect of stabilizing the launcher 1 and ensuring the stability of the launcher 1 when used on uneven ground.
