Description

Technical Field

[0001] The utility model relates to the field of firecrackers, in particular to a firecracker with a red envelope. Background Art

[0002] Traditional firecrackers are usually made of gunpowder, paper tubes and fuses. By lighting the fuse, the firecrackers make a sound, thereby setting off the atmosphere of the New Year. However, the functions of traditional firecrackers are relatively simple, with only two steps: lighting the firecrackers and waiting for the firecrackers to burn out. Simply setting off firecrackers makes it less interesting, and it is not convenient for young people to participate in the step of lighting the firecrackers. The process of waiting for the firecrackers to burn out is rather boring, causing some young people to leave early without waiting for the firecrackers to burn out. Utility Model Content

[0003] In order to overcome the shortcomings of traditional firecrackers that are relatively simple in function, less interesting, inconvenient for young people to participate in the process of lighting firecrackers, and rather boring in the process of waiting for firecrackers to burn out, the utility model provides a firecracker with a red envelope, which can automatically scatter the red envelope after the firecrackers are set off, thereby increasing the participation of young people and making the atmosphere more festive.

[0004] The technical solution is as follows: A firecracker with a red envelope, including a cylinder, a hollow cylinder, a hanging rope, a hinged seat, a rotating shaft, a fan-shaped plate and a release mechanism. The lower part of the cylinder is open, a hollow cylinder is installed at the center of the cylinder, a hanging rope is installed on the top of the cylinder, and several hinged seats are evenly spaced on the outer circumference of the lower part of the cylinder. A rotating shaft is rotatably provided on each hinged seat, and a fan-shaped plate is fixedly installed on each rotating shaft. A release mechanism is provided on the hollow cylinder, and the release mechanism is used to limit or release several fan-shaped plates.

[0005] Preferably, the plurality of fan-shaped plates can close the opening at the bottom of the cylinder when they are closed.

[0006] Preferably, the release mechanism includes a fuse rope, a hexagonal rod, a circular plate and a firecracker body. Two slots are opened on the upper part of the hollow cylinder, and the two slots are symmetrically arranged. The upper end of the fuse rope is connected to the hexagonal rod, and the hexagonal rod is stuck in the two slots. A circular plate is fixedly connected to the middle part of the fuse rope, and the circular plate is located below several fan-shaped plates. The circular plate limits the several fan-shaped plates, and several firecracker bodies are evenly spaced at the lower part of the fuse rope.

[0007] Preferably, a transparent observation panel is further included. Two transparent observation panels are embedded and installed on the cylinder body, and the two transparent observation panels are symmetrically arranged.

[0008] Preferably, a counterweight ball is further included, and a counterweight ball is installed on a side of each sector plate away from the rotating shaft.

[0009] The beneficial effects of the present invention are: 1. The operator ignites the lower end of the fuse rope, which slowly ignites upwards, and the firecracker bodies on the fuse rope will be detonated in sequence from bottom to top. When the fuse rope burns to the circular plate, the fuse rope at the circular plate will turn into ashes, and the fuse rope will no longer fix the circular plate, and the circular plate will no longer limit the six fan-shaped plates. Under the action of the six fan-shaped plates' own gravity, the six fan-shaped plates will swing away from each other, and the red envelopes in the cylinder will fall out from the open part of the lower part of the cylinder, thus completing the scattering of red envelopes after setting off firecrackers, thereby increasing the participation of the younger generation, and scattering the red envelopes right after setting off firecrackers, making the atmosphere more festive.

[0010] 2. Through the transparent observation board, the operator can easily see the amount of red envelopes placed in each cylinder, so that the cylinder with different numbers of red envelopes can be selected according to the scene.

[0011] 3. Under the action of the counterweight ball, the six fan-shaped plates can swing more smoothly in directions away from each other, thereby increasing the opening speed of the six fan-shaped plates, increasing the speed of the red envelopes falling, and further improving the smoothness of the connection between the firecrackers and the red envelopes.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1: A firecracker with a red envelope, such as Figure 1-5As shown, it includes a cylinder 1, a hollow cylinder 2, a hanging rope 21, a hinged seat 3, a rotating shaft 4, a fan-shaped plate 5 and a release mechanism. The lower part of the cylinder 1 is open, and a hollow cylinder 2 is installed at the center of the cylinder 1. A hanging rope 21 is installed on the top of the cylinder 1. Several hinged seats 3 are installed at uniform intervals on the outer circumference of the lower part of the cylinder 1 by welding. A rotating shaft 4 is rotatably provided on each hinged seat 3 through a bearing, and a fan-shaped plate 5 is fixedly installed on each rotating shaft 4. A release mechanism is provided on the hollow cylinder 2, and the release mechanism is used to limit or release several fan-shaped plates 5.

[0020] When a plurality of sector plates 5 are closed, the opening at the bottom of the cylinder 1 can be closed.

[0021] The release mechanism includes a fuse rope 7, a hexagonal rod 8, a circular plate 9 and a firecracker body 10. Two slots 6 are opened on the upper part of the hollow cylinder 2, and the two slots 6 are symmetrically arranged. The upper end of the fuse rope 7 is connected to the hexagonal rod 8, and the hexagonal rod 8 is stuck in the two slots 6. A circular plate 9 is fixedly connected to the middle part of the fuse rope 7. The circular plate 9 is located below several sector plates 5. The circular plate 9 limits the several sector plates 5. Several firecracker bodies 10 are evenly spaced at the lower part of the fuse rope 7.

[0022] Initially, an appropriate amount of fuse rope 7 is wound around the hexagonal rod 8. When a red envelope needs to be put into the cylinder 1, the operator first lifts up the hexagonal rod 8 to separate the hexagonal rod 8 from the two slots 6, and then the operator rotates the hexagonal rod 8 to unwind the fuse rope 7 on the hexagonal rod 8. The circular plate 9 on the fuse rope 7 moves in the direction away from the hollow cylinder 2, and the circular plate 9 no longer limits the six sector plates 5. After the six sector plates 5 are opened in the direction away from each other, the operator can put an appropriate amount of red envelope into the cylinder 1 through the opening at the bottom of the cylinder 1, and then the operator closes the six sector plates 5 in the direction close to each other, and then the operator pinches the hexagonal rod 8 and rotates the hexagonal rod 8 in the opposite direction to rewind the fuse rope 7. The fuse rope 7 drives the circular plate 9 to move in the direction close to the hollow cylinder 2, and the six sector plates 5 can be limited again through the circular plate 9. After the ignition is completed, the ignition coil 7 is ignited, and the ignition coil 7 is turned into ashes ...

[0023] Example 2: Based on Example 1, Figure 1-Figure 5 As shown, a transparent observation panel 11 is also included. Two transparent observation panels 11 are embedded and installed on the cylinder 1. The two transparent observation panels 11 are symmetrically arranged and are made of acrylic material.

[0024] A counterweight ball 12 is also included. A counterweight ball 12 is installed on one side of each sector plate 5 away from the rotating shaft 4.

[0025] Through the transparent observation plate 11, the operator can easily see the amount of red envelopes placed in each cylinder 1, so that the cylinder 1 with different numbers of red envelopes can be selected according to the scene.

[0026] Under the action of the counterweight ball, the six fan-shaped plates 5 can swing more smoothly in directions away from each other, thereby increasing the opening speed of the six fan-shaped plates 5, increasing the falling speed of the red envelope, and further improving the smoothness of the connection between the firecrackers and the red envelope.

[0027] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
