[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example 1: In this example, Figures 1-6 As shown, a mounting structure for a built-in light source of fireworks comprises a shell 3 at the rear of a fireworks body 1. A square through-hole 4 is provided on the surface of the shell 3 to facilitate fixing a fixing base 5 on the outside of the shell 3, so as to facilitate installation of a light-emitting component 15, a power supply 7, and a switch 8. The mounting structure also comprises a fixing mechanism and a clamping mechanism. The fixing mechanism is arranged on the outside of the shell 3 to provide power to the light source. The clamping mechanism is arranged on the inside of the shell 3 to fix the position of the light source. Before using the mounting structure for the built-in light source of fireworks, first check whether the structure can be used normally. By fixing the fixing mechanism and the clamping mechanism together, the light source can be fixed to the fixed position. The structure is put into a state to be used. The fixing mechanism includes a fixing base 5. The fixing base 5 and components such as the card column can be made of materials similar to the outer shell, which is convenient for production and mass production. A groove 6 is provided inside the fixing base 5, and a power supply 7 is provided inside the groove 6, which is convenient for taking out the power supply 7 and replacing it. A switch 8 is provided on one side of the power supply 7 to match the power supply 7. An operating port 9 adapted to the switch 8 is provided on the surface of the fixing base 5. The power supply 7 is controlled by the switch 8, so that the luminous effect of the luminous component 15 can be achieved by pressing the switch 8, and the light-transmitting effect of the luminous component 15 can be achieved through the hollow portion 2.

[0033] Among them Figure 3-Figure 6 As shown, the clamping mechanism includes a first clamping column 10 fixedly connected to the fixing seat 5. The first clamping column 10 passes through the through hole 4 on the shell 3 and is adapted to the specifications of the through hole 4. A plurality of baffles 11 are fixedly installed on the side of the first clamping column 10 away from the fixing seat 5. The baffles 11 can be made of a material with good elasticity, so that when the first clamping column 10 is plugged in, the baffles 11 can be in a compressed state. After plugging in, the baffles 11 can be opened. Due to the limiting effect of the baffles 11, there is a gap between the first clamping column 10 and the shell 3. In the gap where only the latch 12 can move, a latch 12 is also clamped on the outer side of the first clamping column 10. A clamping groove 13 is provided on the surface of the latch 12 to match the first clamping column 10. During installation, one end of the first clamping column 10 is first inserted through the through hole 4 to fix the position of the first clamping column 10 and the fixing seat 5. After aligning the first clamping column 10 with the clamping groove 13, the upper half of the latch 12 is pressed so that the latch 12 can be smoothly clamped on the outer side of the first clamping column 10, thereby fixing the power supply 7. Figure 4 As shown, a protective plate 14 is fixed to one side of the fixing base 5 by a number of bolts, thereby confining the power supply 7 inside the fixing base 5, so that the fixing base 5 and the protective plate 14 can form a complete box body;

[0034] Among them Figure 4As shown, a light-emitting component 15 is connected to one side of the power supply 7. The power supply 7 is electrically connected to the light-emitting component 15. The light-emitting component 15 is configured as a light strip or a light bead. An opening for passing the light-emitting component 15 is provided on the upper surface of the fixing base 5. One end of the power cord of the light-emitting component 15 first passes through the opening, then extends through the through hole 4 to the interior of the housing 3, and then is bonded to the inner wall of the housing by glue or other materials.

[0035] Among them Figure 6 As shown, the upper half of the latch 12 is curved, making it easier to move the latch 12 to the desired position and improving the user experience. During use, first place the power supply 7 inside the fixing base 5, then insert the power cord of the light-emitting component 15 and the first latch 10 into the housing 3 through the through hole 4. The latch 12 is then inserted from one side of the first latch 10, and the fixing base 5 is secured to the back of the housing 3, completing the installation.

[0036] Embodiment 2: The difference from embodiment 1 is that Figure 7 and Figure 8 As shown, the clamping mechanism includes a fixing column 16 fixedly connected to the fixing seat 5, a sliding sleeve 17 is fixedly installed on one side of the fixing column 16, and a telescopic rod 18 is slidably connected inside the sliding sleeve 17, which can stretch the telescopic rod 18 out, so that when one end of the fixing column 16 is inserted through the through hole 4, the elastic clip 19 can be smoothly in a compressed state, which facilitates the elastic clip 19 to pass through the through hole 4. A connecting block is fixedly installed on one side of the telescopic rod 18, and the upper and lower ends of the connecting block are rotatably connected to the elastic clip 19 through the support seat. The elastic clip 19 is made of a material with good elasticity, so that when the fixing column 16 is inserted, the elastic clip 19 can be in a compressed state. After plugging in, the elastic clip 19 can be opened, so that the power supply 7 is installed on one side of the housing 3. The upper and lower ends of the connecting block are provided with limit plates 20 for limiting the rotation angle of the elastic clip 19, so that the rotation angle of the elastic clip 19 is within a specific range, and the maximum rotation angle is less than 90°, thereby increasing the stability of the structure. The connecting block is fixedly connected to the sliding sleeve 17 by a number of bolts, so that after the plugging operation is completed, the distance between the rotating end of the elastic clip 19 and the housing 3 is shortened, thereby reducing the movement range of the fixing seat 5. The end of the elastic clip 19 can be fixedly connected to the housing 3 by bolts or glue materials to fix the position of the power supply 7;

[0037] Among them Figure 7 and Figure 8 As shown, the fixing column 16 passes through the through hole 4 and is adapted to the specifications of the through hole 4, so that the elastic clip 19 can smoothly clamp the power supply 7 to one side of the shell 3, increasing the applicability of the structure and adapting to different types of fireworks.

[0038] When in use, first place the power supply 7 into the fixing base 5, stretch out the telescopic rod 18 so that the elastic clip 19 is in a compressed state, and then insert the power cord of the light-emitting component 15 and the fixing column 16 into the shell 3 from the through hole 4. After the plugging is completed, open the elastic clip 19, fix the sliding sleeve 17 to the connecting block with the bolt, and then clamp the fixing base 5 on the back of the shell 3 to complete the installation.

[0039] Example 3: The difference from Example 1 and Example 2 is that Figure 9 As shown, the clamping mechanism also includes a second clamping column 21 fixedly connected to the fixing base 5. The second clamping column 21 passes through the through hole 4 on the shell 3 and is adapted to the specifications and dimensions of the through hole 4. The surface of the second clamping column 21 is provided with a socket, and the interior of the socket is provided with a pin 22. It uses fewer parts, has a simple structure, and is easy to operate. It only needs to insert the pin 22 into the socket.

[0040] When in use, first place the power supply 7 into the fixing seat 5, then insert the second clamping column 21 into the shell 3 from the through hole 4. After the plugging is completed, insert the pin 22 into the socket so that the fixing seat 5 is stuck on the back of the shell 3, thereby completing the installation.

[0041] Example 4: The difference from Example 1 is that Figure 10 As shown, the latching mechanism includes a cylindrical third latching post 23 fixedly connected to the fixing base 5 and a second latching bolt 24. The third latching post 23 passes through the through-hole 4 and is sized to fit within the through-hole 4. The third latching post 23 is provided with two slots 25 for the second latching bolt 24 to engage. During operation, the second latching bolt 24 can be inserted into the slot 25 selected as needed. The third latching post 23 also has a cavity 26 for passage of a power cord, etc.

[0042] When in use, first place the power supply 7 into the fixing base 5, then insert the power cord of the light-emitting component 15 and the third clamping column 23 into the shell 3 through the through hole 4, insert the second clamping bolt 24 into a slot 25 according to the fixing needs, and clamp the fixing base 5 on the back of the shell 3 to fix it, thereby completing the installation.

[0043] Example 5: The fixing base 5 is also provided with a hollow portion 2, a power supply 7, a switch 8, an operating port 9, etc. The difference from Example 1 is that Figure 11 、 12 As shown in Figures 1 and 13, the snap-fit mechanism includes a hook 26 fixedly connected to the fixing base 5. A pressure plate 27 is provided at the upper end of the hook 26. The hook 26 is inserted into the upper end of the housing 3. The housing cover 28 is placed on the housing 3 and abuts against the pressure plate 27, securing the fixing base 5 to the back of the housing 3, thus completing the installation. A hook slot 29 is provided at the upper end of the housing 3 for the hook 26 to engage, so that the pressure plate 27 is flush with the upper end of the housing 3.

[0044] Direct hooking and clamping can be used, and the through hole 4 does not need to be provided on the shell 3.

[0045] An opening for passing the light emitting component 15 is provided on the upper surface of the fixing base 5 . One end of the power line of the light emitting component 15 first passes through the opening and then extends to the interior of the housing 3 through the upper port of the housing 3 .

[0046] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
