Description

Technical Field

[0001] The utility model relates to a Gatling firework with a telescopic handle. Background Art

[0002] In the prior art, Chinese patent publication CN219083909U discloses a "Gatling Firework." In standby mode, the handle retracts and hides within an outer tube. In operation, the handle extends without affecting normal use. This effectively reduces the product's packaging length. Specifically, the handle slides within a core tube. A bushing is fixedly mounted at the bottom end of the core tube, which is fixedly mounted within the bottom end of the outer tube. The core tube is located within the inner cavity of the outer tube between the bottom end of the bead-dispensing product and the bottom end of the outer tube.

[0003] In practice, it is found that the above technical solution still needs to be improved to further reduce the packaging length of the product. Utility Model Content

[0004] In order to solve the above-mentioned drawbacks, the technical problem to be solved by the present invention is to provide a Gatling firework with a telescopic handle, which can further effectively reduce the packaging length of the product. In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is a Gatling firework with a telescopic handle, wherein a plurality of bead-emitting products are assembled and installed in an outer tube, and a handle body is provided at the bottom end of the outer tube. In the standby state, the handle body is slidably sleeved in the core tube, and in the working state, the handle body extends out of the outer tube. The invention is characterized in that it also includes a fixed sleeve composed of an inner sleeve and an outer sleeve, and the bottom end of the core tube is snap-connected to the inner sleeve to achieve axial connection; a plurality of bead-emitting products are arranged around the circumference of the outer wall of the core tube, and the lower part of the bead-emitting products is inserted into the annular space between the inner sleeve and the outer sleeve, and the bottom of the annular space is provided with an abutment for abutting the bottom end of the bead-emitting products; the handle body is provided with a tapered neck near the top, and the inner wall of the inner sleeve is provided with a tapered neck opening corresponding to the tapered neck.

[0005] The beneficial effect of the present invention is that, in addition to the function of maintaining the contraction of the handle body, the lower part of the bead-discharging product arranged around the core tube is inserted into the annular space of the fixed sleeve, thereby further effectively reducing the packaging length of the product; at the same time, the abutment parts ensure that the arrangement heights of the bead-discharging products are consistent, and the necessary firing distance is maintained between the bottom end of the bead-discharging product and the bottom port of the outer tube to ensure safety.

[0006] In one embodiment, the tapered neck is provided with a plurality of slits evenly distributed along the circumference; the outer wall of the inner sleeve is provided with a plurality of sloped protrusions evenly distributed along the circumference; the inner wall of the core tube near the bottom end is provided with a sloped step ring; and the inner wall of the bottom end of the core tube is provided with a sloped collar, which is arranged corresponding to the sloped protrusions, with the stepped portion of the sloped step ring abutting the top end of the inner sleeve. This achieves reliable and convenient assembly and meets the requirements of the handle's extension and retraction, effectively simplifying the structure and facilitating connection and assembly. Furthermore, a ridge ring is provided between the sloped collar and the sloped step ring, embracing the outer wall of the inner sleeve. This further reduces the clearance between the outer wall of the core tube and the inner sleeve, resulting in a more secure connection.

[0007] In one embodiment, the top end of the core tube is provided with a core tube cap. This prevents glue from being produced during fireworks production from dripping into the standby core tube, causing the core tube to adhere to the handle within it and preventing the handle from being pulled into operation. Core tube caps of varying lengths can also be adjusted to accommodate the length difference between the bead-producing product and the outer tube. Furthermore, the top of the core tube cap is provided with a firework fixing point to enhance the fireworks display effect.

[0025] See attached Figure 1-10 , reflecting a specific structure of the present invention. The Gatling fireworks with a telescopic handle are a plurality of bead-emitting products 6 assembled and installed in an outer tube 4. A handle body 1 is provided at the bottom end of the outer tube 4. In the standby state, the handle body 1 is slidably sleeved in the core tube 2. In the working state, the handle body 1 extends out of the outer tube. It also includes a fixed sleeve 3 composed of an inner sleeve 301 and an outer sleeve 302. A plurality of bead-emitting products 6 are arranged around the circumference of the outer wall of the core tube 2. The lower part of the bead-emitting product 6 is inserted into the annular space between the inner sleeve 301 and the outer sleeve 302, thereby further effectively reducing the packaging length of the product. An abutment 305 is provided at the bottom of the annular space to abut the bottom end of the bead-emitting product 6, ensuring that the arrangement height of each bead-emitting product 6 is consistent, and the necessary firing distance is maintained between the bottom end of the bead-emitting product 6 and the bottom end of the outer tube 4 to ensure safety. In the example, the abutment 305 is a plurality of prisms evenly arranged around the circumference of the outer wall of the inner sleeve 301, and the top of the prism abuts the bottom end of the bead-emitting product 6. In other embodiments, the abutment member 305 may also be other structures, such as a step arranged around the circumference of the inner wall of the outer sleeve 302 .

[0026] In the example, the handle body 1, the core tube 2, and the fixing sleeve 3 can be separately injection molded and then assembled. The description in the example is based on the handle body 1 being at the bottom.

[0027] The handle 1 has a tapered neck 101 near the top. In this example, the handle 1 is tapered overall. In other embodiments, the handle may have other shapes other than the tapered neck 101. The tapered neck 101 has a plurality of cracks 102 evenly distributed along the circumference.

[0028] The fixed sleeve 3 includes an inner sleeve 301 fixed at the bottom end and an outer sleeve 302, the outer sleeve 302 is used to connect to the outer cylinder 4. The inner wall of the inner sleeve 301 is provided with a tapered neck portion 304 corresponding to the tapered neck 101, and the outer wall of the inner sleeve 301 is provided with a plurality of sloped protrusions 303 evenly distributed along the circumference.

[0029] A sloped step ring 201 is provided on the inner wall of the core tube 2 near its bottom end. A sloped collar 202 is provided on the inner wall of the bottom end of the core tube 2. This collar 202 corresponds to the sloped protrusion 303, with the stepped portion 2011 of the sloped step ring 201 abutting the top of the inner sleeve 301. In this example, a ridged ring 203 is provided between the sloped collar 202 and the sloped step ring 201, embracing the outer wall of the inner sleeve 301. This ridged ring 203 further reduces the clearance between the outer wall of the core tube and the inner sleeve.

[0030] During assembly, the bottom end of the core tube 2 is pressed down firmly so that it fits over the inner sleeve 301 of the fixed sleeve 3. After the ramp collar 202 passes over the ramp bump 303, the core tube 2 is blocked and cannot move upward. Simultaneously, the stepped portion 2011 of the ramp step ring 201 on the inner wall of the core tube 2 abuts the top of the inner sleeve 301, preventing the core tube 2 from descending, thereby achieving axial positioning between the core tube 2 and the fixed sleeve 3. The handle 1 is then inserted into the core tube 2. Assembly is complete, and the telescopic handle is now in a standby state, effectively reducing the product's packaging length.

[0031] To enter the working state, the handle 1 is dragged downward, and its tapered neck 101 elastically contracts along the crack 102, reducing its radial dimension and passing through the slope portion 2012 of the slope step ring 201. After the tapered neck 101 recovers, the step portion 2011 of the slope step ring 201 abuts against the top of the handle 1, preventing it from moving upward. Simultaneously, the tapered neck 101 of the handle 1 is locked within the tapered neck opening 304 of the inner sleeve 301, preventing it from moving downward, thereby achieving axial positioning of the handle 1 and the fixed sleeve 3. At this point, the handle 1 extends from the bottom end of the inner sleeve 301 of the fixed sleeve 3, entering the working state.

[0032] The core tube 2 only needs to be provided with a circle of sloped collar 202 and a circle of sloped step ring 201 on the inner wall, the fixed sleeve 3 only needs to be provided with a number of sloped protrusions 303 on the outer wall of the inner sleeve, and the handle body 1 and the inner sleeve 301 have corresponding conical fit, so as to achieve reliable and convenient assembly and meet the needs of the handle body extension and contraction, without the requirement of circumferential alignment, effectively simplifying the structure and facilitating connection and assembly.

[0033] Since the telescopic handle body needs to be combined with the bead-spitting fireworks during the production of fireworks, glue is needed in the combination. In order to prevent the glue in the production of fireworks from dripping into the core tube 2 in the standby state, the core tube 2 is bonded to the handle body 1 placed therein, and the handle body 1 cannot be pulled into the working state. In the example, the top port of the core tube 2 is provided with a core tube cap 5. In production practice, core tube caps 5 of different lengths can also play a role in adjusting the length of the core tube 2, so that core tube caps 5 of different lengths can be applied according to the length difference between the bead-spitting fireworks and the outer tube 4. The top of the core tube cap 5 can also be provided with a fireworks fixing part (not shown in the figure) to add a fireworks fixing position to enrich the firing effect.

[0034] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the present invention to the specific implementation methods described. Obviously, many modifications and changes can be made based on the contents of this specification.
