Description

Technical Field

[0001] The utility model relates to the field of fireworks explosion-proof equipment, in particular to a fireworks rocket explosion-proof safety device. Background Art

[0002] Fireworks and rockets are special pyrotechnic products that contain flammable and explosive gunpowder components. Under certain conditions, these gunpowders can burn rapidly and release huge amounts of energy, thus forming colorful fireworks effects. The packaging boxes used for fireworks during handling and transportation are all sealed structures. After the box is subjected to external temperature conduction, the lack of air circulation inside the box will gradually increase the temperature inside the box. The increased high temperature will accelerate the chemical reaction rate of the gunpowder in the fireworks, making it more likely to reach the critical point of explosion, causing safety accidents. In view of this, an explosion-proof safety device for fireworks and rockets is proposed. Utility Model Content

[0004] Furthermore, the carrier plate is a continuous circular structure, with extension rods provided at the four corners above the inner carrier, and matching sockets provided at the four corners of the top of the outer cover plate, and the extension rods are plugged into the sockets.

[0005] Furthermore, the top of the extension rod is provided with an external thread with depth, the extension rod and the socket are fixed by a nut, and a rectangular heat-insulating groove is also provided in the wall of the outer covering plate.

[0007] Furthermore, a horizontal array of slide bars is provided above the inner carrier, and the slide bars are plugged into the inner bottom edge below the carrier.

[0008] Beneficial effect: the carrier plate is inserted into the sliding strip of the inner carrier plate, the fireworks rockets are placed in the two empty spaces of the carrier plate, and then the fiberglass insulation board is inserted into the insulation groove of the outer cover plate, and then the four extension rods of the inner carrier plate are aligned with the jacks at the four corners above the outer cover plate, and the device is fixed with nuts to complete the explosion-proof protection of the fireworks rockets. The fiberglass insulation board in the insulation groove of the outer cover plate can allow the external hot air to pass through the insulation board to isolate the heat outside, and at the same time keep the carrier plate in a sealed state, isolating the oxygen in the outer cover plate, so that the fireworks rockets are not easily affected by high temperature and explode. When removing the outer cover plate, the fireworks rockets inserted on the circular carrier plate can be easily removed by personnel, and the sliding strip on the inner carrier plate can effectively ensure the stability of the carrier plate, further improving the practicality of the device.

[0016] Please refer to Figures 1 to 5 ;

[0017] This embodiment provides a fireworks and rocket explosion-proof safety device, comprising an inner carrier 2, a carrier plate 3 for preventing the fireworks placed therein from being squeezed is provided above the inner carrier 2, and an outer covering plate 1 for heat insulation is provided above the carrier plate 3; Figures 1 to 5 , the carrier plate 3 is a continuous circular structure, with extension rods 201 provided at the four corners above the inner carrier 2, and matching sockets 103 provided at the four corners of the top of the outer cover plate 1. The extension rods 201 are plugged into the sockets 103, and the top of the extension rods 201 is provided with a deep external screw thread. The extension rods 201 and the sockets 103 are fixed by nuts. A rectangular heat-insulating groove 101 is also provided in the wall of the outer cover plate 1, and a heat-insulating board 102 with the same groove spacing as the heat-insulating groove 101 is plugged into the heat-insulating groove 101. The heat-insulating board 102 is made of glass fiber. A horizontal array of slide bars 202 is also provided above the inner carrier 2, and the slide bars 202 are plugged into the inner bottom edge of the bottom of the carrier plate 3;
