Description

Technical Field

[0001] The utility model relates to the field of fireworks accessories, in particular to a universal display shell firing base. Background Art

[0002] The base of the fireworks shells is used to prevent the launch tube from tipping over and ensure the stability of the fireworks during the firing process. This helps the fireworks to be fired according to the predetermined trajectory and effect, avoiding accidents.

[0003] In the prior art, a clamp-type adjusting bolt is used to clamp and fix the display shells to the base. This fixing method requires frequent tightening and loosening of the screws when loading and unloading the display shells, and requires additional adjustment tools for the screws. The display shells are difficult to load and unload, and the loading and unloading efficiency is low. At the same time, a single-sized clamp is difficult to fix display shells of multiple sizes, and multiple-sized clamps are required for fixation. The applicability of the device is not high.

A circular array of rotating shaft holes is distributed on the upper surface of the circular ring of the rotating card seat and penetrates to the bottom surface of the rotating card seat. A truncated cone-shaped torsion spring table is arranged at the center of the bottom surface of the rotating card seat. A hand pull rod is arranged on one side of the rotating card seat, and the sliding card shaft seat is rotatably passed through the rotating card seat.

[0007] Furthermore, the main body of the sliding card shaft seat is a truncated cone-shaped rotating shaft block, and the upper and lower surfaces of the rotating shaft block are eccentrically provided with T-stage cylindrical eccentric shaft rods. The side wall of the rotating shaft block close to the eccentric shaft rod is connected with a cylindrical sliding card table through ribs. The eccentric shaft rod of the sliding card shaft seat is rotatably inserted into the rotating shaft hole of the rotating seat, and the sliding card table of the sliding card shaft seat is slidably embedded in the fixed seat.

[0008] Furthermore, the main body of the fixed seat is disc-shaped, and a circular notch-shaped torsion spring groove is arranged in the center of the upper surface of the fixed seat. Three outer stoppers with arc-shaped rotating snaps on the inner side distributed in a circular array are arranged on the periphery of the upper surface of the fixed seat. A sliding groove is arranged on the top of the outer stopper of the fixed seat, and the sliding stopper of the sliding stopper shaft seat is slidably embedded in the sliding groove of the fixed seat.

[0009] Furthermore, a torsion spring is clamped in the torsion spring groove of the fixed seat, and the torsion spring fixing sleeve is arranged on the outer wall of the torsion spring platform of the rotating clamping seat, and the torsion spring platform of the rotating clamping seat is rotatably inserted into the torsion spring groove.

[0010] Beneficial effect: the eccentric shaft rod of the sliding card shaft seat is rotatably inserted into the shaft hole of the rotating card seat, and the sliding card platform of the sliding card shaft seat is slidably embedded in the sliding card groove of the fixed seat. A torsion spring is arranged between the torsion spring groove of the fixed seat and the torsion spring platform of the rotating card seat. When the rotating card seat is rotated, the three circumferentially distributed sliding card shaft seats on the rotating card seat are driven to rotate eccentrically synchronously, and the clamping space between the sliding card shaft seats is enlarged, so that a large-diameter fireworks tube can be clamped and fixed. When the rotating card seat is not subjected to external force, the torsion spring is released to drive the rotating card seat to reverse, and the sliding card shaft seat rotates eccentrically in the opposite direction, and the clamping space between the sliding card shaft seats is tightened, and the clamped fireworks tube is tightly fixed. The loading and unloading effect of the fireworks shells is realized through the eccentric rotation transformation of the sliding card shaft seat, and no other supporting tools are required. The loading and unloading convenience and efficiency are high. At the same time, the sliding card shaft seat can directly change the clamping size infinitely through eccentric rotation, thereby realizing the clamping and fixation of fireworks shells of multiple sizes and improving the versatility of the device.
