[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-7 As shown, a firework lamp with a folding function comprises a main shell, and a plurality of lamp tubes 4 are rotatably installed at the circumferential edge position of the main shell, and the lamp tubes 4 have two extreme states relative to the main shell, namely, unfolding and folding. When unfolding, the ends of the plurality of lamp tubes 4 disperse and expand in a direction away from the center of the main shell, and when folding, the ends of the plurality of lamp tubes 4 close in a direction close to the center of the main shell, that is, the lamp tubes 4 of the firework lamp are always connected to the main shell. Since the number of the lamp tubes 4 of the firework lamp is large, there are 12 lamp tubes 4 in this example, the structure of the lamp tubes 4 connected to the main shell can replace the method in the prior art that the lamp tubes 4 need to be disassembled and assembled one by one. When in use or at the end of use, the lamp tubes 4 can be used or folded by simply rotating them relative to the main shell, which has the advantages of convenient operation and time saving.

[0026] A movable plate for limiting the position of the lamp tube 4 when the lamp tube 4 is unfolded is detachably installed on the lower surface of the main shell. When the firework lamp is in use, the lamp tube 4 is in an unfolded state. More specifically, the length of the lamp tube 4 is perpendicular to the center line of the main shell. In order to prevent the lamp tube 4 from rotating in this state, a movable cover 3 is installed on the lower surface of the main shell. When the lamp tube 4 is about to rotate, the lamp tube 4 will contact the movable cover 3 and be in a limited state, so that the lamp tube 4 can always be in an unfolded state.

[0027] Specifically, when the lamp tube 4 is in the expanded state, the length direction of the lamp tube 4 is perpendicular to the center line of the main shell; when the lamp tube 4 is in the folded state, the length direction of the lamp tube 4 is parallel to the center line of the main shell. These two states are the extreme states when the lamp tube 4 rotates relative to the main shell, and are also the structural states when in use and not in use. In addition, in both states, the length direction of the lamp tube 4 can be in a non-perpendicular and non-parallel state with the center line of the main shell, so that the lamp tube 4 can have a larger angular rotation range without limitation.

[0028] Specifically, the main shell has a accommodating cavity 8 at the center position, and a circuit board, a switch button and a power module are installed in the accommodating cavity 8. A light strip 7 is installed inside the lamp tube 4, and the front end of the light strip 7 extends toward the center direction of the main shell and is electrically connected to the circuit board. That is, the accommodating cavity 8 inside the main shell is installed with electrical components for making the light strip 7 glow, and the electrical components can be hidden in the accommodating cavity 8, which has the advantages of being waterproof, dustproof and impact-proof. The structure and principle of the electrical components making the light strip 7 glow belong to conventional means in the prior art and will not be elaborated here.

[0029] Specifically, the main shell includes a top cover 1 and a fixed plate 2 that are fixedly connected. More specifically, the top cover 1 and the fixed plate 2 can be connected by snap-fit ​​connection or screw connection to achieve assembly between the top cover 1, the fixed plate 2 and the lamp tube 4, and to facilitate the installation of electrical components in the accommodating cavity 8; the edges of the top cover 1 and the fixed plate 2 are both provided with grooves for accommodating the front end of the lamp tube 4, and semicircular grooves are provided on both sides of the grooves and at the position where the top cover 1 and the fixed plate 2 contact, and the semicircular grooves of the top cover 1 and the fixed plate 2 form a circular hole.

[0030] Among them, the edge of the top cover 1 has a uniformly distributed first groove 101, and the first groove 101 has first semicircular grooves 102 on both sides. The edge of the fixed plate 2 is provided with a second groove 201 matching the position of the first groove 101, and the second groove 201 has second semicircular grooves 202 on both sides. After the top cover 1 and the fixed plate 2 are assembled, the space formed by the first groove 101 and the second groove 201 can accommodate the front end area of ​​the lamp tube 4, and the first semicircular groove 102 and the second semicircular groove 202 can form a circular hole structure.

[0031] Specifically, both sides of the front end of the lamp tube 4 have outwardly protruding shafts 6, which are inserted into the circular hole to realize the rotation of the lamp tube 4 relative to the main shell. In order to make the fireworks lamp have more functions and usage states, the shaft 6 and the circular hole can be connected in a tight fit. Furthermore, there is a certain friction between the two side walls of the front end of the lamp tube 4 and the groove, so that the lamp tube 4 can be rotated to any angle under the action of friction. For example, in one state, the lamp tube 4 rotates to a position between two extreme states. At this time, the fireworks lamp can have an umbrella-shaped structure, or can be adjusted to other shapes according to user needs. It has the advantages of diverse functions and strong entertainment.

[0032] Specifically, the surface of the fixed disk 2 is provided with a plurality of mounting holes 203 which are through-set, and the mounting holes 203 are arc-shaped holes, the center of the arc coincides with the circle of the fixed disk 2, and the plurality of mounting holes 203 are evenly distributed around the center of the fixed disk 2. A protruding L-shaped locking block 301 is provided on the inner surface of the movable cover 3, and the locking block 301 can be inserted into the mounting hole 203, and when the movable cover 3 rotates, the locking block 301 is utilized to clamp and connect the movable cover 3 to the fixed disk 2. In actual use, the movable cover 3 can be disassembled and assembled by rotating the movable cover 3, and the operation is convenient.

[0033] Specifically, among the multiple lamp tubes 4, an extension tube 5 is hinged at the end of one of the lamp tubes 4. The extension tube 5 can be used as a support for the firework lamp and can be stored inward when not in use.

[0034] When the firework lamp with folding function is in use, the movable cover 3 is installed on the lower surface of the fixed plate 2, and the unfolded lamp tube 4 can be limited so that the lamp tube 4 is in a Figure 1 When not in use, the movable cover 3 is disassembled, and the lamp tube 4 can be rotated along the center of the shaft 6, so that the lamp tube 4 is closed toward the center direction, as shown in the unfolded state. Figure 7 As shown, the lamp tube 4 can be stored. This foldable firework lamp replaces the traditional method of assembling and disassembling one by one, and has the advantages of convenient unfolding and storage and saving time.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
