Description

Technical Field

[0001] The utility model relates to a firing type fireworks device, in particular to a fireworks device which uses compressed air to fire light pieces such as sequins, ribbons, colored paper pieces or similar light pieces into the air and let them float down. Background Art

[0002] There is a fireworks cannon device on the market that can spray colorful fireworks into the air. The fireworks sprayed into the air will scatter and gradually fall, making it suitable for use in celebratory occasions such as wedding banquets, opening ceremonies, etc.

[0003] There are many firework cannon devices that use compressed air to spray the firework pieces into the air. Usually, the compressed air is filled into a metal compressed air storage bottle in advance, and the compressed air storage bottle is airtightly plugged with a plug unit, and then the plug unit is fixed with a safety unit to store the compressed air in the compressed air storage bottle for a long time.

[0004] The fireworks can be divided into electronically released and manually released types. The electronically released fireworks usually use wires to fix the safety unit, and the fixing wires are burned out by the electrothermal effect to release the safety unit, thereby allowing the compressed air in the compressed air storage bottle to push open the plug unit. The released compressed air further sprays the fireworks into the air. The electronically released fireworks require electricity in the barrel part itself, so the electronically released fireworks will also have a base part to supply electricity. Therefore, when the barrel part and the base part are installed, the barrel part needs to be electrically connected to the base part using wires, which is not convenient for disassembly and installation.

[0005] Furthermore, although the safety unit of the electronically released firework cannon is fixed by wires, the wires are at risk of breaking, and the manufacturing process of bundling the wires is also complicated. Utility Model Content

[0006] Therefore, the purpose of the utility model is to provide a firing type fireworks device.

[0007] The utility model provides a firing type fireworks device, comprising:

[0008] A compressed air storage bottle, wherein compressed air is stored;

[0009] A plug unit, comprising a plug body airtightly and removably combined with the compressed air storage bottle, the plug unit further comprising a movable striker, the striker being constructed to be movably and airtightly combined with the compressed air storage bottle and the plug body respectively, and the striker being movable to a ready position and a pushing position;

[0010] A safety unit is arranged on the outside of the plug unit, and the safety unit can be set to an unfired state and a fired state. When the firing pin is located at the ready position, the safety unit remains in the unfired state. When the firing pin is located at the pushing position, the safety unit is pushed to switch to the fired state, and the plug body is separated from the compressed air storage bottle. The compressed air in the compressed air storage bottle is suitable for pushing a plurality of firework pieces to be sprayed into the air.

[0011] The barrel portion of the utility model sets the safety unit to a firing state by displacing the firing pin that passes through the compressed air storage bottle in an airtight manner, so that the plug unit is separated from the compressed air storage bottle to release the compressed air to spray each of the firework pieces into the air.

[0012] In one embodiment, in the firing type firework cannon device, the safety unit further comprises a safety piece movably arranged on the outside of the safety unit, the safety piece can be displaced to a safety position and an unfired position, when the safety piece is located at the safety position, the safety unit can only be fixed in an unfired state, the firing pin can only be maintained at the ready position, when the safety piece is located at the unfired position, the firing pin can be displaced to the pushing position, and the safety unit can form a firing state.

[0013] The safety piece of the safety unit can limit the safety unit to remain in the unfired state when it is not combined with the base part, ensuring that the firework pieces in the filling tube will not be ejected into the air by compressed air under unexpected conditions.

[0014] In one embodiment, the safety unit also includes a pressing part that is arranged above the plug body and can be pivoted, and a pivotable external fastener. When the safety part is in the safety position, the pressing part cannot pivot, and the pressing part restricts the external fastener from pivoting. When the safety part is in the unfastened position, the pressing part can pivot. When the firing pin is in the preparatory position, the external fastener remains stationary. When the firing pin moves from the preparatory position to the pushing position, the external fastener is pushed by the firing pin to pivot. The external fastener pushes the pressing part to pivot so that the safety unit is switched to the firing state. Further, the plug body is pushed by the compressed air in the compressed air storage bottle and separated from the compressed air storage bottle.

[0015] The outer fastener cooperates with the firing pin, and when the firing pin moves to the pushing position, the outer fastener will definitely push the pressing member to pivot, further ensuring that the barrel part will definitely be fired.

[0016] In one embodiment, the safety unit also includes a pivotable inner fastener, which includes a through hole. When the firing pin is located in the preparation position, the firing pin does not pass through the through hole. The inner fastener is located between the plug body and the outer fastener. The inner fastener is unable to push the pressing member to pivotally engage with the pressing member. When the pressing member is unable to pivot, the pressing member restricts the inner fastener from pivoting. The inner fastener presses the plug body and prevents it from being separated from the compressed air storage bottle. When the firing pin is located in the pushing position, the firing pin passes through the through hole to push the outer fastener to pivot. The outer fastener pushes the pressing member to pivot, so that the pressing member is separated from the inner fastener. The plug body is pushed by the pressure in the compressed air storage bottle to press the inner fastener to pivot, so that the plug body is completely separated from the compressed air storage bottle.

[0017] The buckling design of the inner fastener cooperates with the pressing piece to ensure that the inner fastener cannot pivot without the pressing piece pivoting to separate from the inner fastener, thereby further ensuring that the plug body cannot be separated from the compressed air storage bottle. Therefore, the fireworks device of the utility model has good safety.

[0018] The safety unit further comprises a pivot seat which is sleeved with the compressed air storage bottle, the pivot seat comprises a first pivot, a second pivot and a third pivot, the second pivot is adjacent to the third pivot and is located between the third pivot and the first pivot, the inner fastener comprises an end which tilts toward an end away from the compressed air storage bottle, the inner fastener is pivotally connected to the first pivot, the outer fastener further comprises two outer pivots which are spaced apart from each other and a gap formed between the two outer pivots, the outer fastener further comprises a An inner end, the two outer pivots are pivotally connected to the third pivot, the pressing piece also includes a first limiting portion and a second limiting portion adjacent to the first limiting portion, the pressing piece is pivotally connected to the second pivot and is located in the gap, the end and the second limiting portion are constructed so that the inner fastener cannot push the pressing piece to pivotally engage, when the safety unit is in an unfired state, the first limiting portion blocks the top of the inner end, and when the safety piece is in the unlocked position and the firing pin moves to the pushing position, the inner end presses against the first limiting portion to cause the pressing piece to pivot.

[0019] The end is combined with the second limiting part so that the pressing part cannot be pushed to pivot. Therefore, even if the safety part is in the released position, the plug body cannot push the inner fastener to pivot, so that the safety unit can be maintained in the unfired state, avoiding the problem that the safety unit can accidentally form a fired state after the barrel part is sleeved with the sleeve tube, thereby providing good safety for the installation of the barrel part.

[0020] In one embodiment, the firing fireworks device further comprises:

[0021] A filling tube, comprising a filling chamber, wherein the filling chamber is suitable for accommodating a plurality of the firework pieces;

[0022] A connecting piece is combined with the filling cylinder, the connecting piece includes an upper chamber, the connecting piece further forms a groove on the outer peripheral surface and a breach connecting the groove and the upper chamber, the pressing piece is aligned with the breach, the safety piece includes a blocking portion formed on the inner peripheral edge, the safety piece and the connecting piece are slidably engaged, the blocking portion is located in the groove, when the safety piece is in the safety position, the blocking portion is located in the breach and adjacent to the pressing piece, causing the pressing piece to be unable to pivot, when the safety piece is in the released safety position, the blocking portion is located in the groove and separated from the breach and the pressing piece, causing the pressing piece to be pivotable, and when the safety unit is in the firing state, a portion of the pressing piece is located in the breach.

[0023] The safety piece ensures that the pressed part cannot pivot before the barrel part is combined with the base part, and further restricts the firing pin from moving to the pushing position, thereby ensuring that the compressed air in the compressed air storage bottle will not be accidentally released. After the barrel part is combined with the base part, the safety piece will automatically move to the released position, so that the barrel part can be fired. Such a design combines safety and convenience.

[0024] In one embodiment, in the percussion-type fireworks device, the plug unit also includes a conduit, the conduit includes a pipe extending along the axial direction of the conduit, the compressed air storage bottle includes a neck and a bottom end separated from the neck, the plug body is airtightly and removably combined with the neck, the plug body also includes a combining hole, the outer surface of one end of the conduit is airtightly combined with the combining hole, the other end of the conduit passes through the bottom end of the compressed air storage bottle and is airtightly combined with the bottom end, the pipe of the conduit is separated from the internal space of the compressed air storage bottle storing compressed air, the firing pin includes a first end and a second end, the firing pin and the pipe of the conduit can be relatively slidably combined, the first end and the second end of the firing pin are both located on the outside of the conduit, and the first end of the firing pin extends out of the bottom end of the compressed air storage bottle, and when the firing pin is located at the pushing position, the second end of the firing pin triggers the safety unit to switch to the firing state.

[0025] The plug unit of the utility model is respectively combined with the plug body and the compressed air storage bottle in an airtight manner through the conduit, and the conduit extends out of the outside of the compressed air storage bottle, so that the compressed air in the compressed air storage bottle cannot leak out from the pipeline. Therefore, the conduit well supports the striker to be able to move airtightly relative to the compressed air storage bottle.

[0026] In one embodiment, the safety unit also includes a pressing piece and an external fastener, which are arranged above the plug body and can be set to be pivotable and non-pivotable. The pressing piece includes a first limiting portion located above the external fastener. When the pressing piece cannot pivot, the first limiting portion limits the external fastener from pivoting and the external fastener limits the firing pin from moving to the pushing position. When the firing pin is located in the preparatory position, the second end of the firing pin is separated from the external fastener. When the pressing piece is set to be pivotable and the firing pin is located in the pushing position, the second end of the firing pin pushes the external fastener to pivot. The external fastener includes an inner end that presses against the first limiting portion, causing the pressing piece to pivot so that the safety unit forms the firing state.

[0027] In one embodiment, the firing fireworks device further comprises:

[0028] A safety piece is movably arranged on the outside of the safety unit, and the safety piece can be moved to a safety position and a release safety position. When the safety piece is located at the safety position, the safety piece restricts the pressing piece from pivoting. When the pressing piece cannot pivot, the external fastener cannot pivot either, and the plug body cannot be separated from the compressed air storage bottle. When the safety piece is located at the release safety position, the pressing piece can pivot.

[0029] In one embodiment, the safety unit also includes a pivotable inner fastener, which includes a through hole. When the firing pin is located in the preparation position, the inner fastener is located between the plug body and the outer fastener, and the inner fastener presses the plug body. The inner fastener includes an end that is engaged with a second limiting portion included in the pressing member, and the pressing member limits the inner fastener from pivoting, and the inner fastener limits the plug body from detaching from the compressed air storage bottle. When the firing pin is located in the preparation position, the second end of the firing pin does not pass through the through hole. When the pressing member is pivotable and the firing pin is located in the pushing position, the second end of the firing pin passes through the through hole to push the outer fastener to pivot. The inner fastener is separated from the pressing member and can pivot, and further the plug body pushes the inner fastener open and is separated from the neck.

[0030] In one embodiment, the firing fireworks device further comprises:

[0033] A base part, the base part includes a sleeve tube, the connecting piece can be detachably combined with the sleeve tube, when the connecting piece has not yet been combined with the sleeve tube, the safety piece is located at the safety position, the firing pin can only be fixed in the ready position, and the safety unit can only be fixed in the unfired state, when the connecting piece is combined with the sleeve tube, the safety piece is pushed by the sleeve tube and moved to the released safety position, the firing pin can be moved to the pushing position, and the safety unit can be in the fired state.

[0034] The installation and disassembly of the barrel part and the base part are quite simple, and the barrel part can be installed and disassembled quickly.

[0035] In one embodiment, the firing fireworks device further comprises:

[0036] A driver is fixed in the sleeve tube, and the driver includes a movable part facing the striker. When the driver is powered on, the movable part is displaced to push the striker from the preparation position to the push position.

[0037] In one embodiment, in the percussion-type fireworks device, the base portion also includes a shell and a longitudinal sleeve fixed on the shell, the base portion also includes a rotating table pivotally connected to the longitudinal sleeve, the sleeve pipe is pivotally connected to the rotating table, the rotating table allows pivoting along a longitudinal axis included in the longitudinal sleeve together with the connecting member, and the sleeve pipe allows pivoting about a transverse axis perpendicular to the longitudinal axis.

[0038] In one embodiment, in the percussion-type fireworks device, the base portion also includes a longitudinal axis disc pivotally connected to the rotating table, the longitudinal axis disc is accommodated in the shell, the base portion also includes an extension arm fixed in the shell, the extension arm includes a first connecting end fixed to the shell and a second connecting end away from the first connecting end, the extension arm also includes a threaded portion formed between the first connecting end and the second connecting end, a longitudinal axis resistance member fixed at the second connecting end faces the longitudinal axis disc, the base portion also includes a longitudinal axis knob pivotally connected to the shell, the longitudinal axis knob is threadedly connected to the threaded portion, rotating the longitudinal axis knob can change the longitudinal axis resistance member to be close to or away from the longitudinal axis disc, the greater the pressure of the longitudinal axis resistance member in contact with the longitudinal axis disc, the greater the resistance of the rotating table to pivot around the longitudinal axis sleeve.

[0039] The longitudinal axis resistance member cooperates with the longitudinal axis disc to generate appropriate friction resistance, so that the barrel part can be easily and quickly adjusted to the desired direction.

[0040] In one embodiment, in the percussion-type fireworks device, the longitudinal axis disc has a semicircular cross-section, and the shell includes a limit rod, and the limit rod cooperates with the longitudinal axis disc with a semicircular cross-section to limit the rotation angle of the rotating platform to less than 360°.

[0041] The semicircular longitudinal axis disc cooperates with the limit rod to limit the rotating table from rotating 360° (it can pivot approximately 180°). This design helps prevent the wires connected to the driver from being entangled and pulled apart due to the pivoting of the rotating table.

[0042] In one embodiment, in the percussion-type fireworks cannon device, the rotating platform also includes a connecting portion and two extension portions fixed at both ends of the connecting portion, each extension portion includes an inner cover, and a locking portion is fixed on each of the two inner covers.

[0043] Although the rotating platform cannot rotate 360°, the rotating platform can support the sleeve to pivot around the transverse axis, so the sleeve can still support the barrel to achieve 360° angle and direction adjustment. The transverse axis resistance members cooperate with the transverse axis discs to generate appropriate friction resistance, so that the barrel can be easily and quickly adjusted to the desired angle.

[0044] In one embodiment, the firing fireworks device further comprises:

[0045] a base portion including a sleeve;

[0046] a connecting piece, wherein the compressed air storage bottle, the plug unit and the safety unit are accommodated in the connecting piece, and the connecting piece includes a snap-fitting portion; and

Each of the transverse axis resistance members 70 is located between each of the transverse axis discs 64 and the outer cover 50 along the transverse axis. Therefore, when each of the transverse axis knobs 68 is displaced in a direction parallel to the transverse axis, each of the transverse axis resistance members 70 can approach or move away from each of the transverse axis discs 64. Each of the transverse axis resistance members 70 can be but is not limited to being composed of a rubber block, a silicone block or a block made of other materials with a high friction coefficient. In addition, since the screw of each of the transverse axis knobs 68 passes through the limiting groove 66 of each of the transverse axis discs 64, each of the connecting members 62, each of the bearings 58 and each of the transverse axis discs 64 can only pivot along the transverse axis within the range of each of the limiting grooves 66.

[0082] The rotating platform 42 also includes a longitudinal axis rod 46 extending from a bottom surface of the connecting portion 44 along a longitudinal axis perpendicular to the transverse axis and a semicircular longitudinal axis disc 28, wherein the longitudinal axis rod 46 is pivotally connected to the longitudinal sleeve 26, and the longitudinal axis disc 28 also includes two stopper portions 29 formed in a semicircular straight line segment, and the longitudinal axis disc 28 is located inside the housing 22 and is pivotally combined with the longitudinal axis rod 46. In essence, the longitudinal axis disc 28 is located between the platform portion 24 and the longitudinal axis resistance member 38 along the longitudinal axis, see Figure 7As shown, when the longitudinal axis resistance member 38 is separated from the longitudinal axis disc 28, the rotating table 42 can pivot around the longitudinal axis. Therefore, it can be understood that the greater the contact pressure between the longitudinal axis resistance member 38 and the longitudinal axis disc 28, the greater the resistance to the rotation of the rotating table 42, so that the rotating table 42 can be fixed.

[0083] The base portion 20 further includes a sleeve tube 72 pivotally connected to the rotating platform 42. The sleeve tube 72 includes two connecting portions 74 extending in a direction parallel to the horizontal axis and arranged in a straight line. In fact, each of the connecting portions 74 can be, but is not limited to, formed by a hole with a non-circular cross section. Each of the connecting portions 74 of the sleeve tube 72 is pivotally connected with each of the connecting members 62. Therefore, it can be understood that each of the connecting members 62 supports the sleeve tube 72 to pivot within the range of each of the limiting grooves 66 with the horizontal axis as the axis center. Figure 6 As shown, when each of the transverse axis resistance members 70 is separated from each of the transverse axis discs 64 and is not in contact with each other, the sleeve tube 72 can smoothly pivot.

[0084] A bracket 76 is fixed in the sleeve 72, and a driver 80 is fixed in the bracket 76. The driver 80 can drive a movable part 82 to produce displacement. The driver 80 can be but is not limited to being composed of a solenoid valve, a motor or other similar motor devices driven by electricity. In the embodiment of the utility model, a solenoid valve is used as an embodiment of the driver 80. Therefore, when the solenoid valve is energized, the movable part 82 will be rapidly displaced by the magnetic force.

[0086] The connecting member 86 further includes two grooves 113 extending from the end surface of the first connecting end 88 to the junction of the middle section 89 and the second connecting end 90, and a break 114 is formed at the lower end of one of the grooves 113 and located at the junction of the middle section 89 and the second connecting end 90, and the break 114 connects the groove 113 and the upper chamber 92, and each groove 113 also includes a locking groove 118 extending from the outer peripheral surface of the first connecting end 88 to the upper chamber 92.

[0087] The connecting member 86 also includes two long grooves 88A extending from the end surface of the first connecting end 88 to the junction of the middle section 89 and the second connecting end 90. The two long grooves 88A are each located between the two grooves 113 in a circumferential direction around a longitudinal axis included in the connecting member 86. Each of the long grooves 88A includes a snap-fit ​​portion 88B, and each of the snap-fit ​​portions 88B is located at the junction of the middle section 89 and the second connecting end 90.

[0088] The barrel portion 84 includes a compressed air storage bottle 115, a plug unit 136 and a safety unit 150 accommodated in the connector 86. The compressed air storage bottle 115 includes a neck 117 and a bottom end 116 separated from the neck 117. The compressed air storage bottle 115 is used to store compressed air. The compressed air storage bottle 115 is accommodated in the lower chamber 94 of the connector 86. The second connector end 90 of the connector 86 is combined with a bottom cover 335. In addition, a lower sealing sheet 333 is provided on the bottom cover 335. The lower sealing sheet 333 can be, but is not limited to, composed of a paper sheet, a film or other similar flexible sheet-like elements that can be punctured or removed.

[0089] The plug unit 136 is airtightly and removably connected to the neck 117 of the compressed air storage bottle 115, and the plug unit 136 includes a plug body 137, a conduit 331 and a striker 315. The plug body 137 includes a coupling hole 139, and the coupling hole 139 extends from a top surface included in the plug body 137 along an axial direction included in the compressed air storage bottle 115 to a bottom surface included in the plug body 137. The plug body 137 can be made of rubber material but is not limited to other materials of similar properties. The plug body 137 is removably plugged in the neck 117, and the outer circumference of the plug body 137 is airtightly fitted with the inner circumference of the neck 117.

[0090] The conduit 331 includes a pipe 332 that penetrates along an axial direction of the conduit 331, the outer peripheral surface of one end of the conduit 331 is airtightly combined with the combination hole 139 of the plug body 137, and the other end of the conduit 331 passes through the bottom end 116 of the compressed air storage bottle 115, and the outer peripheral surface of the other end of the conduit 331 is airtightly combined with the bottom end 116 of the compressed air storage bottle 115. For example, the conduit 331 and the bottom end 116 of the compressed air storage bottle 115 are airtightly combined. The bottom end 116 is welded and fixed so that the outer peripheral surface of the conduit 331 is airtightly combined with the bottom end 116 of the compressed air storage bottle 115. Referring to Figure 5, the other end of the conduit 331 is located outside the bottom end 116 of the compressed air storage bottle 115, so that the pipe 332 of the conduit 331 is separated from the space for storing compressed air inside the compressed air storage bottle 115, and the compressed air in the compressed air storage bottle 115 will not leak out through the pipe 332 of the conduit 331.

[0091] The striker 315 includes a first end 317 whose outer diameter is slightly larger than the inner diameter of the pipe 332 and a second end 319 whose outer diameter is slightly larger than the inner diameter of the pipe 332. The striker 315 is slidably connected to the pipe 332 of the conduit 331, the first end 317 is located at the bottom end 116 of the compressed air storage bottle 115 and the outer side of the conduit 331, and the second end 319 is located at the outer side of the conduit 331. The striker 315 can be displaced along the axial direction of the conduit 331 to a preparatory position (such as Figure 5A to Figure 8 ) and a push position (as shown Fig. 9 shown).

[0092] The safety unit 150 includes a pivot seat 119 that is sleeved around the outer periphery of the neck 117, the pivot seat 119 includes a first pivot 131A, a second pivot 131B and a third pivot 131C, the second pivot 131B is adjacent to the third pivot 131C, the pivot seat 119 also includes a sleeve portion 134 located between the first pivot portion 131 and the second pivot portion 131B, the sleeve portion 134 includes a through hole 138, the second pivot 131B is located between the through hole 138 and the third pivot 131C.

[0093] The neck 117 is sleeved inside the through hole 138 of the sleeve portion 134, and the outer periphery of the sleeve portion 134 is sleeved with the through hole 138 of the pivot seat 119, and the pivot seat 119 is located in the lower chamber 94 of the connecting member 86. Figure 2 , Figure 5AAs shown, in essence, after the sleeve portion 134 and the pivot seat 119 are sleeved with the neck 117 of the compressed air storage bottle 115, the end of the neck 117 is expanded and bent outward, so that the two ends of the sleeve portion 134 are respectively abutted against the expanded end of the neck 117 and the bottle body of the compressed air storage bottle 115 and are fixed.

[0094] The safety unit 150 further includes an outer fastener 157, an inner fastener 151 and a pressing member 173, wherein the pressing member 173 includes a first limiting portion 175 and a second limiting portion 177 adjacent to the first limiting portion 175, and the pressing member 173 further includes a contact edge 173A separated from the first limiting portion 175 and the second limiting portion 177 and a pressing member pivot 174. The pressing member pivot 174 of the pressing member 173 is pivotally connected to the second pivot 131B of the pivot seat 119 and a portion thereof is located in the breach 114 of the connecting member 86 (such as Figure 5A shown).

[0095] The inner fastener 151 includes an inner pivot 153 and an end 155 separated from the inner pivot 153, and the end 155 can be but is not limited to being tilted in the opposite direction of the compressed air storage bottle 115. The inner fastener 151 also includes a through hole 156 formed between the inner pivot 153 and the end 155. The inner fastener 151 is pivotally connected to the first pivot 131A of the pivot seat 119.

[0096] See also Figure 5A to Figure 8 As shown, when the plug body 137 and the neck 117 are airtightly combined, the inner fastener 151 presses against the plug body 137, and the end 155 of the inner fastener 151 and the second limiting portion 177 are configured to engage with each other so as not to push the pressing member 173 to pivot. Therefore, under the premise that the pressing member 173 cannot pivot, the inner fastener 151 cannot pivot, further resulting in the thrust applied by the plug body 137 to the inner fastener 151 being unable to link the pressing member 173 to pivot. In addition, see Figure 5A As shown, when the firing pin 315 is located at the preparation position, the second end 319 of the firing pin 315 does not protrude from the outside of the through hole 156 .

[0097] The outer fastener 157 includes two outer pivots 159 spaced apart from each other and a gap 171 located between the two outer pivots 159 . The outer fastener 157 also includes an inner end 171A adjacent to the gap 171 and located between the two outer pivots 159 .

[0098] The outer pivot portion 159 of the outer fastener 157 is pivotally connected to the third pivot portion 131C of the pivot seat 119 (on the same side as the pressing member 173). Please refer to FIGS. 5 to 6 for details. Figure 8 As shown, the pressing piece 173 is located in the gap 171 of the outer fastener 157 (between the two outer pivots 159), and when the plug body 137 is combined with the compressed air storage bottle 115, the outer fastener 157 is substantially parallel to the inner fastener 151, and the first limiting portion 175 of the pressing piece 173 blocks the upper part of the inner end 171A of the outer fastener 157. Therefore, it can be understood that when the pressing piece 173 cannot pivot, the inner end 171A is restricted by the first limiting portion 175, resulting in the outer fastener 157 being unable to pivot.

[0099] The safety unit 150 also includes a safety piece 179 that is slidably connected to the connecting piece 86. The safety piece 179 can be but is not limited to a ring-shaped or similar structure. The safety piece 179 also includes a blocking portion 191 protruding inward and two snap-fitting portions 193. Each of the snap-fitting portions 193 includes a first portion 193A and a second portion 193B. The first portion 193A of each of the snap-fitting portions 193 protrudes from the outer periphery of the safety piece 179, and the second portion 193B of each of the snap-fitting portions 193 protrudes toward the center of the safety piece 179. In addition, the blocking portion 191 is located between the two snap-fitting portions 193 in a circumferential direction around an axis included in the safety piece 179.

[0100] The safety member 179 is slidably sleeved with the middle section 89 of the connecting member 86, and the blocking portion 191 is slidably received in the groove 113 having the opening 114, see Figure 5B As shown, the two buckling portions 193 are accommodated in the two long grooves 88A. In fact, the safety member 179 can be displaced along the axial direction of the connecting member 86 to a safety position (such as Figure 5A as shown) and an unlocked position (as shown Figure 6 , Figure 8 to Figure 10 shown).

[0101] See also Figure 5A , Figure 5BAs shown, when the barrel portion 84 is not combined with the sleeve tube 72, the safety member 179 is positioned at the safety position, and the second portion 193B of each snap-fitting portion 193 of the safety member 179 is respectively snap-fitted with the locking portion 88B, so that the safety member 179 is fixed at the safety position, and in addition, the blocking portion 191 is located in the breach 114 and is adjacent to the abutting edge 173A of the safety member 179. In such a state, the pressing member 173 cannot pivot, and thus when the pressing member 173 cannot pivot, the outer fastener 157 and the inner fastener 151 are both restricted by the pressing member 173 and cannot pivot, and further, the plug body 137 keeps plugging the compressed air storage bottle 115, so that the compressed air in the compressed air storage bottle 115 will not leak out.

[0102] Therefore, it can be understood that when the safety member 179 is in the safety position, because the external fastener 157 cannot pivot, the second end 319 of the firing pin 315 is blocked by the external fastener 157, so that the firing pin 315 cannot move from the preparation position to the pushing position, thereby ensuring that the plug unit 136 will not be separated from the compressed air storage bottle 115 before the barrel part 84 is combined with the base part 20.

[0103] The barrel portion 84 also includes a stopper 337 fixedly arranged around the outer periphery of the connecting member 86. The stopper 337 can be but is not limited to being composed of an annular body. The stopper 337 includes an inner annular surface with two snap-fitting blocks 339 protruding therefrom. The two snap-fitting blocks 339 are spaced apart from each other in a circumferential direction around a longitudinal axis included by the stopper 337.

[0104] The stopper 337 is sleeved on the outer periphery of the first connecting end 88 of the connecting member 86 and is adjacent to the middle section 89. The two engaging blocks 339 are accommodated in the groove 113 and are engaged with the engaging slots 118. After the two engaging blocks 339 are substantially moved to align with the grooves 113, the stopper 337 is further pivoted about the longitudinal axis of the connecting member 86 so that the two engaging blocks 339 are engaged with the engaging slots 118, so that the position of the stopper 337 along the longitudinal axis of the connecting member 86 is fixed, as shown in FIG. Figure 5A , Figure 5B As shown, the stopper 337 is located on the first engaging end 88 and is adjacent to the middle section 89 . When the safety member 179 is located at the safety position, the safety member 179 is spaced apart from the stopper 337 along the longitudinal axis of the engaging member 86 .

[0105] The barrel portion 84 also includes a filling tube 195, an outer skin 196 and an upper cover 313 which are sleeved with the connecting piece 86. The filling tube 195 is a hollow tube structure and includes a filling chamber 197. The outer skin 196 is coated on the outer circumference of the filling tube 195. The upper cover 313 is combined with one end of the filling tube 195 and covers the filling chamber 197. A group of the upper cover 313 extending from the outer periphery is located between the outer skin 196 and the filling tube 195.

[0106] The other end of the filling tube 195 is sleeved with the first connecting end 88 of the connecting piece 86 and abuts against the upper surface of the stopper 337. A plurality of fixing members 198 are passed through the outer skin 196, the filling tube 195 and the first connecting end 88 of the connecting piece 86, so that the filling tube 195 and the outer skin 196 are fixedly connected to the connecting piece 86. The filling chamber 197 of the filling tube 195 is used to accommodate a plurality of firework pieces (not shown in the figure), the grid portion 111 of the connecting piece 86 is used to prevent each of the firework pieces from falling into the connecting piece 86 and allow compressed air to pass through, and the upper cover 313 is used to prevent each of the firework pieces from falling out of the outside of the filling chamber 197.

[0107] The barrel portion 84 of the fireworks cannon device 10 of the present invention is designed to be disposable, that is, after the fireworks pieces in the barrel portion 84 are ejected into the air by the compressed air in the compressed air storage bottle 115, the barrel portion 84 can be directly separated from the base portion 20 and a new barrel portion 84 can be installed. The barrel portion 84 is essentially the second connecting end 90 of the connecting member 86 sleeved into the sleeve tube 72, see Figure 5B , Figure 5C , Figure 8 As shown, the barrel portion 84 is displaced along the axial direction of the sleeve 72 toward the driver 80 until the bottom cover 335 abuts against the bracket 76 , so that the first end 317 of the firing pin 315 is aligned with the movable part 82 of the driver 80 .

[0108] During the displacement of the barrel portion 84 toward the driver 80, the first portion 193A of each of the two buckling portions 193 is squeezed by an upper end surface of the sleeve tube 72, so that the two buckling portions 193 are elastically deformed toward the bottom wall of the two long grooves 88A, and further, the two second portions 193B are separated from the two engaging portions 88B, so that the safety member 179 can be displaced relative to the connecting member 86 along the middle section 89. As the barrel portion 84 gradually displaces toward the driver 80, the safety member 179 is pressed by the upper end surface of the sleeve tube 72 and moves relative to the connecting member 86 from the safety position (such as Figure 5A As shown in the figure, the pressing member 173 is displaced to the released position, and further the blocking portion 191 of the safety member 179 is separated from the opening 114 and accommodated in the groove 113. In this state, the pressing member 173 is no longer hindered by the blocking portion 191, so that the pressing member 173 can pivot.

[0109] It should be noted that even if the safety piece 179 is in the unfastened position, the pressing piece 173 remains stationary. The reason is that even if the safety piece 179 is in the unfastened position, under the premise that the external fastener 157 does not push the pressing piece 173 to pivot, the end 155 of the internal fastener 151 and the second limiting portion 177 are constructed to engage with each other in a manner that cannot push the pressing piece 173 to pivot. In this way, even if the internal fastener 151 is pushed by the plug body 137, the end 155 of the internal fastener 151 cannot push the pressing piece 173 to pivot. Furthermore, the internal fastener 151 still presses against the plug body 137 and cannot be separated from the compressed air storage bottle 115. The safety unit 150 is defined as an unfired state in this state.

[0110] If the driver 80 is powered on, the movable member 82 of the driver 80 is displaced, and the movable member 82 pushes the lower sealing sheet 333 away and presses the first end 317 of the striker 315, so that the striker 315 is displaced from the preparation position to the pushing position, and further the second end 319 of the striker 315 presses the outer fastener 157 to pivot, see Fig. 9 As shown, when the outer fastener 157 pivots, the inner end 171A of the outer fastener 157 presses against the first limiting portion 175 to cause the pressing member 173 to pivot, and further, the second limiting portion 177 of the pressing member 173 is separated from the end 155 of the inner fastener 151, so that the inner fastener 151 is released and can pivot.

[0111] See also Fig. 9 , Fig.10As shown, after the inner fastener 151 can pivot, the plug body 137 is pushed by the compressed air in the compressed air storage bottle 115 to separate from the neck 117, and the plug body 137 also pushes the inner fastener 151 to pivot.

[0112] It can be understood that after the plug body 137 is separated from the neck 117, compressed air is ejected from the outside of the compressed air storage bottle 115, and the compressed air enters the filling chamber 197 of the filling tube 195 through the grid portion 111 of the connector 86. The compressed air further pushes the upper cover 313 to separate from the filling tube 195 and ejects each of the firework pieces into the air, creating an effect of each of the firework pieces falling from the air.

[0113] After the fireworks in the filling tube 195 have been launched into the air, the barrel portion 84 can be separated from the base portion 20. In fact, this can be achieved by simply pulling out the barrel portion 84 along the axial direction of the sleeve tube 72 in a direction away from the driver 80. A new and unused barrel portion 84 can also be quickly combined with the base portion 20.

[0114] The fireworks device 10 of the present invention can also adjust the direction and angle of the barrel portion 84 through the mechanism of the rotating platform 42, see Figure 11 to Figure 14 Specifically, when each of the horizontal axis knobs 68 is rotated to a state where each of the horizontal axis resistance members 70 is separated from or slightly in contact with each of the horizontal axis discs 64 (eg, Figure 6 As shown in the figure, the resistance generated by each transverse axis resistance member 70 to each transverse axis disc 64 is not high, so that the barrel portion 84 and the sleeve tube 72 can easily adjust the angle with the transverse axis as the pivot center. After the barrel portion 84 is adjusted to an appropriate angle, the transverse axis knobs 68 are rotated to increase the pressure of each transverse axis resistance member 70 against each transverse axis disc 64. In this way, the pivot resistance between each transverse axis disc 64 and each bearing 58 becomes larger, so that the angle of the barrel portion 84 can be fixed.

[0115] Furthermore, when the longitudinal axis resistance member 38 is in slight contact or no contact with the longitudinal axis disc 28, the entire rotating platform 42 can be easily pivoted around the longitudinal axis to change the direction of the barrel portion 84. When the direction of the barrel portion 84 is determined, the longitudinal axis knob 40 is rotated to increase the pressure of the longitudinal axis resistance member 38 against the longitudinal axis disc 28. In this way, the resistance of the rotating platform 42 to pivoting about the longitudinal axis will become greater, further fixing the direction of the barrel portion 84.

[0116] See also Fig.14As shown, the semicircular longitudinal axis disc 28 cooperates with the limit rod 25 to limit the rotating table 42 from rotating 360° (it can pivot approximately 180°). This design helps prevent the wires connected to the driver 80 from being entangled or broken due to the pivoting of the rotating table 42.

[0117] Although the rotating platform 42 cannot rotate 360°, the rotating platform 42 can support the sleeve 72 to pivot around the transverse axis, so that the sleeve 72 can still support the barrel portion 84 to achieve 360° angle and direction adjustment.

[0118] By cooperating with each of the transverse axis resistance members 70 and each of the transverse axis discs 64 to generate appropriate friction resistance, the barrel portion 84 can be easily and quickly adjusted to a desired angle.

[0119] The longitudinal axis resistance member 38 cooperates with the longitudinal axis disc 28 to generate appropriate friction resistance, so that the barrel portion 84 can be easily and quickly adjusted to a desired direction.

[0120] The installation and removal of the barrel portion 84 and the base portion 20 are quite simple, and the barrel portion 84 can be quickly installed and removed.

[0121] The barrel portion 84 of the present invention sets the safety unit 150 to a firing state by displacing the firing pin 315 that passes through the compressed air storage bottle 115 in an airtight manner, so that the plug unit 136 is separated from the compressed air storage bottle 115 to release the compressed air to spray each of the firework pieces into the air.

[0122] The end 155 and the second limiting portion 177 are unable to push the pressing piece 173 to pivotally couple, so that even if the safety piece 179 is in the released position, the plug body 137 still cannot push the inner fastener 151 to pivot, so that the safety unit 150 can be maintained in the unfired state, avoiding the problem of the safety unit 150 accidentally forming a fired state after the barrel part 84 is sleeved on the sleeve tube 72, thereby providing good safety for the installation of the barrel part 84.

[0123] The plug unit 136 of the utility model is respectively airtightly combined with the plug body 137 and the compressed air storage bottle 115 through the conduit 331. The conduit 331 extends out of the outside of the compressed air storage bottle 115, so that the compressed air in the compressed air storage bottle 115 cannot leak out from the pipe 332. Therefore, the conduit 331 well supports the striker 315 to be able to move airtightly relative to the compressed air storage bottle 115.

[0124] The safety piece 179 is engaged with the two locking parts 88B through the two locking parts 193, which can ensure that when the barrel part 84 is not combined with the sleeve tube 72, the safety piece 179 is maintained in the safety position, further ensuring that the pressed part 173 cannot pivot and restricting the firing pin 315 from moving to the pushing position, which can ensure that the compressed air in the compressed air storage bottle 115 will not be accidentally released, and when the barrel part 84 is combined with the base part 20, the safety piece 179 will automatically move to the released safety position, so that the barrel part 84 can be fired. Such a design combines safety and convenience.

[0125] The outer fastener 157 cooperates with the firing pin 315 , and when the firing pin 315 moves to the pushing position, the outer fastener 157 will definitely push the pressing member 173 to pivot, further ensuring that the barrel portion 84 will definitely be fired.

[0126] The buckling design of the inner fastener 151 cooperates with the pressing piece 173. Under the premise that the pressing piece 173 is not pivoted and separated from the inner fastener 151, it is ensured that the inner fastener 151 cannot pivot, and further ensures that the plug body 137 cannot be separated from the compressed air storage bottle 115. Therefore, the fireworks device 10 of the utility model has good safety.

[0127] Since the embodiments disclosed in the present invention can be implemented in other specific forms without departing from the spirit or general characteristics of the present invention, and some of these specific forms have been pointed out, the embodiments disclosed in the present invention should be regarded as illustrative rather than restrictive. All changes that fall within the equivalent meaning and scope of the present invention will still be included in the protection scope of the present invention.
