In this embodiment, the pop-up device 1 is the main supporting structure of the entire pop-up bracket, which uses its own elastic force to bounce the upper bearing seat 3 to a certain height, so that the structure carried thereon is lifted to a preset position. In this embodiment, the bearing seat 3 is provided with a plurality of accessory mounting structures 3a, wherein the accessory mounting structure 3a is used to install the corresponding load. In this embodiment, the pop-up device 1 includes: a connecting sleeve 11, a telescopic column 12 coaxially sleeved with the connecting sleeve 11, and an elastic member 13 arranged between the connecting sleeve 11 and the telescopic column 12; in this embodiment, the connecting sleeve 11 as a whole can be set as a regular cylinder (for example, a cylinder) with a certain height, and the corresponding telescopic column 12 as a whole is a regular cylinder with a certain height, wherein, in order to achieve the sliding fit between the telescopic column 12 and the connecting sleeve 11, the outer diameter of the telescopic column 12 can be matched with the inner diameter of the connecting sleeve 11, thereby achieving mutual nesting. In this embodiment, the precision of mutual fit can be achieved by controlling the matching precision between the telescopic column 12 and the connecting sleeve 11, thereby ensuring the movement precision of the pop-up device 1 during the pop-up process. Further, in order to avoid the separation of the telescopic column 12 from the connecting sleeve 11 during the pop-up process, a corresponding limiting structure (for example, mutually matching protrusions and grooves) can be set between the telescopic column 12 and the connecting sleeve 11 to ensure that the telescopic column 12 is stably limited after being lifted to a certain height, and will not separate from the connecting sleeve 11.

[0060] In this embodiment, the pop-up device 1 is in a retracted state and the elastic member 13 is in a compressed state; wherein, the pop-up device 1 is stored in a retracted manner in the initial state to effectively reduce its overall height, thereby reducing its space occupancy and facilitating overall transportation and storage; in addition, by pre-contracting, the supporting seat 3 can also be popped out during the subsequent process, thereby conveniently raising the position of other fireworks structures carried, thereby effectively increasing the fireworks firing effect and ensuring the firing reliability of other fireworks structures.

[0061] Combination Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the present invention, the fixing structure 2 is a plate-shaped structure as a whole, which can be fixedly connected to the bottom end of the connecting sleeve 11 to achieve stable support for the entire pop-up device 1. In this embodiment, the outer shape of the fixing structure 2 is a regular shape, for example, its outer shape can be set to be circular, rectangular, etc.

[0062] Combination Figure 1 , Figure 2 and Figure 3As shown, according to an embodiment of the present invention, the pop-up device 1 further includes: a limiting member 14 for controlling the telescopic state of the elastic member 13. In this embodiment, the limiting member 14 is a rope-like object, which limits the elastic member 13 to be in a compressed state in a complete state, and releases the elastic member 13 when it breaks to drive the telescopic column 12 to pop out. In this embodiment, the limiting member 14 can be set as a soft rope such as a fuse, a cotton thread that can be burned by the fuse, etc., and its strength can meet the restriction of the elastic member 13, and can be destroyed by the sparks in the fireworks during the process of setting off fireworks, so as to facilitate the stable and timely pop-up of the pop-up device 1. For example, the limiting member 14 is set as a fuse, and it can be ignited by other fuses to break when the fireworks are ignited, or the limiting member 14 is set as a cotton thread that can be burned by the fuse. For this purpose, it is connected with other fuses, and it can be burned after the fuse is ignited.

[0063] Combination Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, the two opposite ends of the limiting member 14 are respectively connected to the two opposite sides of the connecting sleeve 11 to compress the elastic member 13 at the bottom of the connecting sleeve 11; in this embodiment, the two opposite sides of the outer side of the connecting sleeve 11 are symmetrically provided with first connecting protrusions 11a, and connecting channels 11b for the limiting member 14 to pass through are respectively provided on the opposite sides of each first connecting protrusion, wherein each first connecting protrusion corresponds to two connecting channels 11b, and thus there are four connecting channels 11b in the circumferential direction of the connecting sleeve 11.

In this embodiment, the elastic member 13 is arranged in the connecting sleeve 11. When the elastic member 13 needs to be compressed and limited, the elastic member 13 is compressed to a preset position, and the limiting member 14 is passed through the connecting channel 11b on the side wall of the connecting sleeve 11 and connected end to end to form a ring structure, wherein the limiting member 14 abuts against the upper end of the elastic member 13, and then, under the elastic restoring force of the elastic member 13, the part of the limiting member 14 outside the connecting sleeve 11 can be limited by the first connecting protrusion to achieve stable compression limitation of the elastic member 13. In this embodiment, the length of the limiting member 14 is determined according to the compression length of the elastic member 13 and the position of the first connecting protrusion, which will not be repeated here. In this embodiment, a limiting groove is provided on the lower side of the first connecting protrusion 11a, which can effectively prevent the limiting member 14 from falling out, which is beneficial to ensuring the reliability of the connection.

[0064] Furthermore, since the limiting member 14 is mainly disposed in the connecting sleeve 11, in order to facilitate the burning of the limiting member 14 during the ignition of the fireworks, the limiting member 14 can be connected with a burnout lead 14a (see Figure 2 and Figure 3) or other structures that can disconnect it to achieve synchronization or distribution with the fireworks ignition process.

[0065] In another embodiment, the two opposite ends of the limiting member 14 are respectively connected to the two opposite sides of the telescopic column 12 to compress the elastic member 13 at the bottom end of the telescopic column 12. In this embodiment, the second connecting protrusions are symmetrically arranged on the two opposite sides of the outer side of the telescopic column 12, and the second connecting protrusions are spaced apart from the bottom end of the telescopic column 12 to facilitate the limiting connection of the limiting member 14. In this embodiment, since the lower end of the telescopic column 12 and the connecting sleeve 11 are mutually slidably arranged inside the connecting sleeve 11, a linear channel for the second connecting protrusion to extend is provided on the side wall of the connecting sleeve 11, and the linear channel is arranged along the axial direction of the connecting sleeve 11, which can facilitate the connection of the limiting member 14 to the second connecting protrusion and can also achieve the limiting connection of the telescopic column 12 when it pops out. In this embodiment, the elastic member 13 is arranged in the connecting sleeve 11. When the elastic member 13 needs to be compressed and limited, the elastic member 13 is compressed to a preset position in the direction of the telescopic column 12, and the limiting member 14 is passed through the linear channel on the side wall of the connecting sleeve 11 and connected end to end to form a ring structure, wherein the limiting member 14 abuts against the lower end of the elastic member 13, and then, under the elastic restoring force of the elastic member 13, the part of the limiting member 14 outside the connecting sleeve 11 can be limited by the second connecting protrusion to achieve stable limitation of the elastic member 13. In this embodiment, the length of the limiting member 14 is determined according to the compression length of the elastic member 13 and the position of the second connecting protrusion, which will not be repeated here. In this embodiment, a limiting groove is provided on the upper side of the second connecting protrusion, which can effectively prevent the limiting member 14 from falling out, which is beneficial to ensuring the reliability of the connection.

[0066] Furthermore, since the limiting member 14 is mainly arranged in the connecting sleeve 11, in order to facilitate it to be burned off during the fireworks ignition process, a burnt fuse or other structure that can disconnect it can be connected to the limiting member 14 to achieve synchronization or distribution with the fireworks ignition process.

[0067] In another embodiment, the two opposite ends of the limiting member 14 are connected to the connecting sleeve 11 and the telescopic column 12, respectively, so that the elastic member 13 is compressed between the connecting sleeve 11 and the telescopic column 12; in this embodiment, a third connecting protrusion can be provided on the outer side of the connecting sleeve 11, and in the vertical direction, one end of the limiting member 14 is connected to the third connecting protrusion, and the other end is connected to the upper end of the telescopic column 12; at this time, the length of the limiting member 14 is determined according to the length of the third connecting protrusion and the telescopic column 12 and the compressed length of the elastic member 13. Thus, the contraction state of the pop-up device 1 can be reliably limited based on the length of the limiting member 14. In this embodiment, the limiting member 14 can be provided as one or more, and its specific number can be determined accordingly according to the need for stable restriction of the pop-up device 1 and the need for convenient release of the elastic member 13, which will not be repeated here. Among them, when the telescopic column 12 is a hollow cylinder, the limiting member 14 can be embedded in the filling part of the telescopic column 12 after the filling of the telescopic column 12 is completed to achieve the fixed connection of the limiting member 14.

[0068] In another embodiment, the two opposite ends of the limiting member 14 are connected to the connecting sleeve 11 and the telescopic column 12, respectively, so that the elastic member 13 is compressed between the connecting sleeve 11 and the telescopic column 12; in this embodiment, a third connecting protrusion can be provided on the outer side of the connecting sleeve 11, and a fourth connecting protrusion can be provided on the outer side of the telescopic column 12. In the vertical direction, the third connecting protrusion and the fourth connecting protrusion can be provided oppositely, so as to facilitate the connection of the two opposite ends of the limiting member 14 with the third connecting protrusion and the fourth connecting protrusion. At this time, the length of the limiting member 14 is determined according to the positions of the third connecting protrusion and the fourth connecting protrusion and the compressed length of the elastic member 13. Thus, the contraction state of the pop-up device 1 can be reliably limited based on the length of the limiting member 14. In this embodiment, the limiting member 14 can be provided as one or more, and its specific number can be determined accordingly according to the need for stable restriction of the pop-up device 1 and the need for convenient release of the elastic member 13, which will not be described in detail here.
