Description

Technical Field

[0001] The utility model relates to the technical field of fireworks, in particular to a fireworks fixing seat capable of pre-installing an ignition head. Background Technique

[0002] At present, in large-scale fireworks shows, safe and advanced ignition methods such as electronic remote control ignition are used to set off fireworks. The traditional way of leaving a fuse outside the fireworks is changed to leaving a lead wire inside the fireworks cylinder, and it is ignited by electronic ignition, which solves the problems of easy explosion and poor safety during transportation in the traditional fireworks industry. There are problems such as troublesome installation or frequent ignition failure due to improper installation when using the existing electronic ignition devices. Therefore, we propose a fireworks fixing seat capable of pre-installing an ignition head to solve the above problems. Content of the Utility Model

An installation hole is opened inside the fireworks setting-off base. A fireworks fixing pipe seat is movably installed inside the fireworks setting-off base through the installation hole. An ignition head body is arranged inside the fireworks setting-off base. A limiting groove is opened on the upper surface of the fireworks setting-off base near the installation hole, and a limiting ring groove is opened inside the fireworks setting-off base near the limiting groove.

[0005] Further, a cross fixing frame is fixedly connected to the inner wall of the fireworks fixing pipe seat. A cylindrical hollow body is fixedly connected to the center of the cross fixing frame. An open port is opened at the bottom end of the cylindrical hollow body. Four installation structures are arranged on the outer wall of the fireworks fixing pipe seat.

[0006] Further, the installation structure includes a limiting block, a movable groove, a rectangular groove, a sliding groove, a movable rod, a movable disk, a resisting spring and a semi-circular block. The outer wall of the limiting block is fixedly connected to the outer wall of the fireworks fixing pipe seat. A movable groove is opened on the upper surface of the limiting block. A rectangular groove is opened on the upper surface of the limiting block near the movable groove. A sliding groove is opened inside the limiting block near the movable groove. A movable rod is movably connected inside the movable groove. The bottom end of the movable rod is fixedly connected to the movable disk. A resisting spring is fixedly connected to the lower surface of the movable disk. The top end of the movable rod is fixedly connected to the semi-circular block.

[0007] Further, a printed circuit board is fixedly installed inside the fireworks ignition base. Elastic conductive posts are arranged on the upper surface of the printed circuit board. A bottom cover is movably installed at the bottom end of the fireworks ignition base. A wire groove is formed inside the lower surface of the bottom cover, and a wire passes through the inside of the wire groove.

[0008] Further, the size of the inside of the rectangular groove is adapted to the size of the semi-circular block. The bottom end of the resisting spring is fixedly connected to the bottom of the inner wall of the sliding groove. The size of the limiting block is adapted to the size of the inside of the limiting ring groove.

[0009] Further, there are three elastic conductive posts. The middle one is the positive electrode, and the two sides are the negative electrodes. The upper ends of the three conductive posts extend into the installation holes, and the wire is electrically connected to the printed circuit board.

[0011] 1. For the fireworks fixing seat with pre-installable ignition heads, by pressing downwards, the bottom ends of the fireworks fixing tube seat and the limiting block are installed inside the installation hole and the limiting groove inside the fireworks ignition base. Then, by rotating, the limiting block moves into the inside of the limiting ring groove. When the limiting block moves into the inside of the limiting ring groove, the movable rod and the movable disc inside the limiting block resist and eject the semi-circular block upwards through the elastic force of the resisting spring, making the installation between the fireworks fixing tube seat and the fireworks ignition base more stable. At the same time, the installation of the fireworks tube can be quickly realized, improving the assembly efficiency, reducing the labor cost, with a simple structure, convenient operation, and ensuring the success rate of igniting the fireworks tube.
