Partitions are uniformly fixedly installed inside both the first and second storage boxes. Exhaust pipes are fixedly installed on the top of the partitions and the bottom of the inner surfaces of both the first and second storage boxes. This design can be used for ventilation and moisture protection during fuse storage, but the partitions occupy space, and their placement makes storing fuses below the partitions inconvenient, resulting in reduced space utilization. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a fuse storage device for combined fireworks production. It has a high space utilization rate, and the storage and retrieval of fuses are unobstructed, resulting in high retrieval efficiency. At the same time, the storage device is equipped with an air bladder. By inflating and deflating the air bladder, the position of the support frame can be adjusted, which facilitates the retrieval of the fuses. The gas filled into the air bladder during the storage of the fuses can be used to accelerate airflow, which is used for ventilation and moisture prevention of the fuses. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for storing fuses used in the production of combined fireworks, comprising a storage box, the top of which is open, a protective cover for sealing the openness being rotatably installed on the side of the storage box, a positioning component for positioning the protective cover on the side of the storage box, an airbag installed in the lower part of the inner cavity of the storage box, a support frame slidably disposed inside the storage box above the airbag, and an air jet component disposed inside the support frame, the airbag communicating with the inner cavity of the air jet component, an inflation pipe communicating with the inner cavity of the airbag being installed on the side of the storage box, and an inflation component disposed outside the storage box.

[0005] As a preferred embodiment of the present invention, the jet assembly includes a jet pipe installed in a support frame, and a plurality of nozzles communicating with the inner cavity of the jet pipe are installed on the side of the jet pipe.

[0006] As a preferred embodiment of this utility model, a connecting pipe communicating with the inner cavity of the airbag is installed on the side of the airbag. The end of the connecting pipe away from the airbag is fixed to the side of the support frame and communicates with the air jet pipe inside the support frame. A pressure relief valve is installed on the connecting pipe.

[0007] As a preferred technical solution of this utility model, a limiting plate is provided on the upper side of the support frame, and an air outlet is provided on the side of the limiting plate near the jet pipe, and a protective net is installed inside the air outlet.

[0008] As a preferred embodiment of this utility model, the inflation assembly includes an air pump group, a main pipe is provided at the air outlet end of the air pump group, and several branch pipes communicating with its inner cavity are installed on the main pipe. The end of the branch pipe away from the main pipe is fixed inside the inflation pipe and communicates with the inflation pipe. A valve is installed on the branch pipe.

[0009] As a preferred embodiment of this utility model, a filter box is provided at the air inlet end of the air pump unit, and the air inlet end of the air pump unit is connected to the inner cavity of the filter box.

[0010] As a preferred embodiment of this utility model, the positioning component includes a positioning post fixed to the side of the protective cover, and a positioning hook is rotatably installed on the upper side of the storage box near the positioning post, and the positioning hook is engaged and adapted with the positioning post.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The combined fireworks production fuse storage device of this utility model connects the inflation component to the inflation pipe. The inflation component inflates the airbag, and the inflation of the airbag pushes the support frame upward, which facilitates the retrieval and placement of the fuse deep in the storage box. During the operation of the inflation component, if the protective cover blocks the opening at the top of the storage box, the airbag cannot inflate effectively. The gas entering the airbag is sprayed out through the jet component for ventilation of the fuse in the storage box, which prevents the fuse from getting damp and deteriorating after long-term storage and ensures the quality of the fuse.

[0013] 2. The fuse storage device for combined fireworks production of this utility model allows for complete gas expulsion from the airbag when a large number of fuses need to be stored in the storage box. At this time, the support frame is located at the bottom of the inner cavity of the storage box, allowing a large number of fuses to be stored in the storage box. Inflating the airbag at this time still allows the gas to be sprayed out through the jet assembly for ventilation. When the storage box is not full of fuses, some gas can be left in the airbag, allowing the support frame to be placed inside the storage box. This facilitates the positioning of the fuses in the storage box by the support frame and the protective cover, reducing the inconvenience of retrieval caused by the fuses being scattered in the storage box during the transfer process.

[0014] 3. The combined fireworks production fuse storage device of this utility model can be set up with multiple storage boxes during use, so as to realize the storage of a large number of fuses. By connecting the set several diversion pipes to the inflation pipes on different storage boxes, one air pump group can inflate multiple storage boxes at the same time, saving costs. When inflating the air bladders in different storage boxes, the valve on the corresponding diversion pipe can be opened. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6This utility model provides a technical solution: a device for storing fuses for the production of combined fireworks, including a storage box 1. The top of the storage box 1 is open, which facilitates the placement of fuses into or removal of fuses stored in the storage box 1. A protective cover 2 is rotatably installed on the side of the storage box 1 to cover and seal the open. The rotation method includes, but is not limited to, a hinged connection or a rotating shaft connection. The protective cover 2 covers and seals the open of the storage box 1, improving the protection effect when storing fuses. A positioning component is provided on the side of the storage box 1 to position the protective cover 2. The positioning component includes a positioning post 17 fixed to the side of the protective cover 2. A positioning hook 18 is rotatably installed on the upper side of the storage box 1 near the positioning post 17, and the positioning hook 18 is engaged with the positioning post 17. By rotating the positioning hook 18 to engage with the positioning post 17, the protective cover 2 is positioned, preventing the protective cover 2 from being opened by force during the transfer or storage of fuses.

[0024] An airbag 4 is installed in the lower part of the inner cavity of the storage box 1, and a support frame 3 is slidably installed inside the storage box 1 above the airbag 4. The support frame 3 is used to support and limit the fuse inside the storage box 1, and an air jet assembly is provided on the inner side of the support frame 3. The airbag 4 is connected to the inner cavity of the air jet assembly. An inflation tube 11 connected to the inner cavity of the airbag 4 is installed on the side of the storage box 1. An inflation assembly is provided on the outside of the storage box 1. The inflation assembly is connected to the inflation tube 11, and air is inflated into the airbag 4 through the inflation assembly. After the airbag 4 is inflated, it expands and pushes the support frame 3 upward, which facilitates the retrieval and placement of the fuse deep inside the storage box 1. During the operation of the inflation assembly, if the protective cover 2 blocks the opening at the top of the storage box 1, the airbag 4 cannot expand effectively. The gas entering the airbag 4 is sprayed out through the air jet assembly for ventilation of the fuse inside the storage box 1, so as to prevent the fuse from getting damp and deteriorating after long-term storage and ensure the quality of the fuse.

[0025] The jet assembly includes a jet pipe 7 installed in the support frame 3, and several nozzles 8 connected to its inner cavity are installed on the side of the jet pipe 7. After the gas in the airbag 4 enters the jet assembly, it is ejected through the nozzles 8 on the jet pipe 7 to accelerate the air flow in the storage box 1 and facilitate ventilation and moisture protection of the fuse.

[0026] The airbag 4 has a connecting pipe 5 installed on its side, which communicates with its inner cavity. The end of the connecting pipe 5 away from the airbag 4 is fixed to the side of the support frame 3 and communicates with the jet pipe 7 inside the support frame 3. A pressure relief valve 6 is installed on the connecting pipe 5. After the airbag 4 is inflated, if the airbag 4 cannot expand effectively due to external constraints, the gas inside the airbag 4 pushes open the pressure relief valve 6 and enters the jet pipe 7 through the connecting pipe 5 and is sprayed out by the nozzle 8. If there are no external constraints on the airbag 4, the pressure relief valve 6 restricts the gas inside the airbag 4, so that the airbag 4 can expand effectively after inflation, which makes it easier for the airbag 4 to push the support frame 3 upward for storing the ignition wire deep inside the box 1.

[0027] When a large number of fuses need to be stored in storage box 1, the gas in airbag 4 can be completely expelled. At this time, support frame 3 is located at the bottom of the inner cavity of storage box 1, and a large number of fuses can be stored in storage box 1. At this time, inflating airbag 4 can still allow gas to be sprayed out through the jet assembly for ventilation. When storage box 1 is not full of fuses, some gas can be left in airbag 4 so that support frame 3 can be set up in storage box 1. This makes it easier for support frame 3 and protective cover 2 to position the fuses in storage box 1, reducing the inconvenience of taking the fuses out of storage box 1 due to stress during transportation.

[0028] A limiting plate 9 is mounted on the upper side of the support frame 3. An air outlet is opened on the side of the limiting plate 9 near the jet pipe 7, and a protective net 10 is installed inside the air outlet. The limiting plate 9 is used to support and limit the ignition wire to prevent the ignition wire from accumulating and blocking the nozzle 8 on the side of the jet pipe 7. The setting of the limiting plate 9 leaves an exhaust space in the support frame 3, which facilitates the jet assembly to spray ventilation.

[0029] The inflation assembly includes an air pump unit 15. A main pipe 12 is provided at the air outlet of the air pump unit 15. Several branch pipes 13 connected to the inner cavity of the main pipe 12 are installed on the main pipe 12. The end of the branch pipe 13 away from the main pipe 12 is fixed inside the inflation pipe 11 and connected to the inflation pipe 11. A valve 14 is installed on the branch pipe 13. Multiple storage boxes 1 can be set up during use to realize the storage of a large number of fuses. By connecting the set branch pipes 13 to the inflation pipes 11 on different storage boxes 1, one air pump unit 15 can inflate multiple storage boxes 1 at the same time, saving costs. When inflating the airbags 4 in different storage boxes 1, the valve 14 on the corresponding branch pipe 13 can be opened.

[0030] A filter box 16 is provided at the air inlet of the air pump unit 15, and the air inlet of the air pump unit 15 is connected to the inner cavity of the filter box 16. During the process of the air pump unit 15 drawing air from the outside, the filter box 16 is used to filter the drawn gas, reduce foreign objects and moisture in the drawn gas, and facilitate ventilation of the ignition wire in the storage box 1.

[0031] The air pump unit 15 used in this utility model is a commonly used electronic component in the prior art. Its working method and circuit structure are well-known technologies. The operation of the air pump unit 15 is controlled by setting a switch group or a PLC controller. This method is a common technical means used by technicians and will not be described in detail here.

[0032] This combination of fireworks production fuse storage device has a high space utilization rate, and the storage and retrieval of fuses are unobstructed, resulting in high retrieval efficiency. At the same time, the storage device is equipped with an air bladder, and the position of the support frame can be adjusted by inflating and deflating the air bladder, which facilitates the retrieval of fuses from deep inside. The gas filled into the air bladder during the storage of fuses can be used to accelerate airflow, which is used for ventilation and moisture protection of the fuses.

[0033] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
