Technical Field

[0001] The invention relates to the technical field of fireworks, and in particular to a novel fireworks base and a fireworks. Background Art

[0002] Fireworks, also known as fireworks, fireworks, and fireworks, are mainly used in military, grand ceremonies or performances. In order to protect the environment, many fireworks formulas do not use substances containing heavy metals and sulfur elements, reducing the generation of sulfur dioxide and other sulfides. The oxygen balance and combustion temperature of the system can also be changed by changing the amount of oxidant and combustibles to control the combustion reaction.

[0003] In order to improve the stability of existing fireworks during firing, a base is usually installed under the fireworks to increase the contact area with the ground and thus improve the stability of firing. However, when processing fireworks, the fireworks and the base are usually processed into an integrated structure, resulting in the fireworks base being discarded together with the fireworks after the fireworks are fired. The fireworks base is difficult to recycle, which is inconsistent with contemporary environmental protection concepts. Summary of the invention

As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms. Embodiment 1

[0025] This embodiment discloses a novel firework base, including a base body 1; a plurality of positioning components for positioning the firework body are arranged on the base body 1; The positioning component includes a clamping rod 8 and a first spring 9. An installation hole for accommodating the positioning component is arranged on the base body 1. One end of the clamping rod 8 is fixedly connected to the first spring 9, and the other end can be clamped with the firework body. In this embodiment, the firework body is positioned through the positioning component, thereby realizing a detachable connection between the firework base and the firework body, enabling the firework base to be recycled after the firework is set off, saving costs and achieving environmental protection at the same time. Embodiment 2

[0026] This embodiment discloses a firework, including a novel firework base as described in Embodiment 1, and further including a firework body and a positioning release mechanism; The firework body is detachably installed on the base body 1. The firework body includes a housing 2 and a plurality of firework cylinders 3. The plurality of firework cylinders 3 are vertically installed inside the housing 2. A positioning plate 5 is provided at the lower part of the housing 2, and a clamping groove 6 that can be clamped with a clamping rod 8 is provided on the positioning plate 5; The positioning release mechanism can be used to release the positioning of the firework body by the positioning assembly.

[0027] Further, in order to improve the smoothness of the cooperation between the positioning plate and the clamping rod, an inclined surface 7 is provided on the upper part of the end of the clamping rod 8 that is clamped with the clamping groove 6. When the housing is installed, the positioning plate at the bottom of the housing first contacts the inclined surface 7, and the clamping rod is squeezed into the installation hole during the contact process. When the clamping groove on the positioning plate is opposite to the position of the clamping rod, the clamping rod extends out of the installation hole into the clamping groove under the action of the first spring and is clamped with the clamping groove. Since the lower end surface of the clamping rod is a plane, the clamping groove can be well limited.

[0028] In this embodiment, further, the positioning release structure includes a firing cylinder 4, a follower column 16 and a connecting component; The firing cylinder 4 is movably arranged inside the housing 2 and is filled with medicine inside. The medicine in the firing cylinder 4 is the last to be ignited; A fixing hole 17 for installing the follower column 16 is provided on the base body 1. The follower column 16 can move up and down in the fixing hole 17. A through hole is provided at the position corresponding to the fixing hole 17 on the housing 2. One end of the follower column 16 can pass through the through hole and contact the lower end surface of the firing cylinder 4; The connecting component is installed in the installation hole. One end of the installation hole is communicated with the fixing hole 17. One end of the connecting component is connected to the first spring 9, and the other end abuts against the follower column 16. When the medicine in the firing cylinder 4 is ignited and launched, the firing cylinder 4 drives the follower column 16 to move downward under the action of the recoil force. When the follower column 16 moves to a specified position, the connecting component drives the clamping rod 8 to retract into the installation hole, thereby releasing the positioning of the positioning plate 5.

[0029] Furthermore, in order to prevent the firing cylinder from moving downward under the action of an external force during transportation or storage, resulting in the positioning release structure being activated to release the positioning of the firework body, the firing cylinder 4 includes a fixed cylinder 19 and a movable cylinder 21. A fixing plate 22 is provided inside the housing 2. The fixed cylinder 19 is vertically and fixedly installed on the fixing plate 22. The movable cylinder 21 is movably installed at the lower end of the fixed cylinder 19. The lower end surface of the movable cylinder 21 abuts against the follower column 16. Among them, the specific installation method between the fixed cylinder and the fixing plate is: a positioning hole for the fixed cylinder 19 to pass through is provided on the fixing plate 22, and a limiting ring 20 that abuts against the upper end surface of the fixing plate 22 is provided on the fixed cylinder 19.

[0030] In the above solution, when the fixed cylinder is fixedly installed on the fixed plate, when the firing cylinder is subjected to external forces during transportation or storage, since the movable cylinder is installed inside the housing, the external forces will only act on the fixed cylinder, and the fixed plate provides a fixing effect on the fixed cylinder. Therefore, the fixed cylinder will not be displaced under the action of external forces, and the firing cylinder at the lower part of the fixed cylinder will not be affected either.

[0031] In this embodiment, specifically, the connecting component includes a connecting rod 10, a limiting plate 12, and a second spring 11. One end of the connecting rod 10 is connected to the first spring 9, and the other end can extend into the fixing hole 17. The limiting plate 12 is installed on the connecting rod 10. An installation cavity 13 for accommodating the limiting plate 12 is provided in the installation hole. The second spring 11 is arranged in the installation cavity 13. One end of the second spring 11 abuts against the limiting plate 12, and the other end abuts against the cavity wall of the installation cavity 13. A mating groove 15 that can cooperate with the connecting rod 10 is provided on the follower column 16. When the follower column 16 moves downward to a specified position, one end of the connecting rod 10 can enter the mating groove 15. Further, in order to enable the follower rod to return to its original position after the base is removed, an inclined surface two 14 is provided on the lower end surface of the end of the connecting rod 10 that cooperates with the mating groove 15. After the base is removed, the operator can pull the follower column upward, and the mating groove squeezes the inclined surface two to retract the connecting rod into the installation hole, thereby resetting the follower column.

[0032] In the above solution, when the drug in the firing cylinder is ignited and ejected, the firing cylinder receives a downward recoil force. The movable cylinder in the firing cylinder moves downward to drive the follower column to move downward. When the follower column moves to a specified position, the connecting rod enters the mating groove under the action of the second spring. During the movement of the connecting rod, the clamping rod is retracted into the installation hole, thereby releasing the positioning of the firework body (as shown in Figure 6 ). Therefore, in this solution, only after the drug in the firing cylinder is burned out can the firework base release the positioning of the firework body, which can prevent the positioning component in the firework from being abnormally released under the action of external forces during transportation or firing, and improves the connection stability between the firework body and the base.

[0033] It should be noted that, in order to prevent the follower column from moving axially during transportation, a damping ring 18 is provided at the lower end of the inner wall of the fixing hole 17. The inner ring of the damping ring 18 contacts the outer circumferential surface of the follower column 16. The damping ring 18 can provide an axial pre-tightening force for the installation of the follower column 16. At the same time, under the action of the second spring, one end of the connecting rod abuts against the outer circumferential surface of the follower column, which can also provide frictional force in the axial direction, further preventing the follower column from moving axially during transportation.

[0034] Among them, the firing cylinder 4 is arranged at the exact center position of the housing 2, and the follower column 16 is installed at the exact center position of the seat body 1.

[0035] The above is only an illustration of the best embodiment of the present invention, but it should not be construed as a limitation to the claims. The present invention is not limited to the above embodiments, and its specific structure allows for variations. All variations made within the scope of the protection of the independent claims of the present invention are within the scope of protection of the present invention.
