Description

Technical Field

[0001] This utility model relates to the field of confetti launchers, and in particular to a fireworks launcher. Background Technology

[0002] Confetti cannons are widely used as a common atmosphere-creating tool in entertainment, celebrations, and special occasions.

[0003] In recent years, with the increasing awareness of environmental protection and the growing demand for convenience, new challenges have been posed to the design of confetti launchers. Traditional fireworks launchers mostly adopt a single-trigger structure, which has the following defects: (1) a single launch cavity cannot achieve nested layered launch; (2) it cannot simultaneously accommodate the alternating launch of different items such as confetti and toys.

[0004] Therefore, a technical solution to the above problems is needed. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the purpose of this utility model is to provide a fireworks launcher to solve the above-mentioned technical problems.

[0006] To achieve its purpose, the present invention adopts the following technical solution:

[0007] A fireworks launcher, comprising:

[0008] The base is equipped with an inner locking mechanism and an outer locking mechanism;

[0009] An inner pusher is movably mounted on the base, and the inner pusher is locked on the base by the inner locking mechanism;

[0010] An internal elastic element is installed on the base and located between the base and the internal pushing element, and can generate an elastic force on the internal pushing element.

[0011] The inner cylinder is rotatably mounted on the base and fitted onto the outside of the inner pusher, forming an internal storage space between the inner cylinder and the inner pusher.

[0012] An external pusher is movably mounted on the base, and the external pusher is locked on the base by the external locking mechanism;

[0013] An external elastic element is installed on the base and located between the base and the external pushing element, and can generate an elastic force on the external pushing element;

[0014] An outer cylinder is rotatably mounted on the base and fitted onto the outside of the outer pusher, with an outer receiving space formed between the outer cylinder and the outer pusher;

[0015] When the outer cylinder rotates under force, it drives the outer pushing member to rotate, and the outer pushing member drives the inner cylinder to rotate. The inner cylinder drives the inner pushing member to rotate, so that the outer pushing member can be unlocked from the outer locking mechanism. Under the action of the outer elastic member, the outer pushing member impacts the outer receiving space. The inner pushing member can be unlocked from the inner locking mechanism, and under the action of the inner elastic member, the inner pushing member impacts the inner receiving space.

[0016] Preferably, the outer accommodating space surrounds the outer side of the inner accommodating space.

[0017] Preferably, both the outer pusher and the outer cylinder are fitted over the outer side of the inner cylinder, and the outer cylinder and the outer pusher form the outer accommodating space.

[0018] Preferably, the inner cylinder has an inner annular rib for supporting the baffle plate on its inner side.

[0019] Preferably, the inner side of the outer cylinder is provided with an outer annular rib for supporting the baffle.

[0020] Preferably, the outer cylinder has a first strip-shaped protrusion, and the outer pusher has a first recess for engaging with the strip-shaped protrusion. The outer cylinder can rotate by engaging the first strip-shaped protrusion with the first recess.

[0021] Preferably, the outer pusher is provided with a second recessed notch, and the outer cylinder is provided with a second strip-shaped protrusion for engaging with the second recessed notch. The outer pusher can drive the inner cylinder to rotate by engaging with the second recessed notch through the second strip-shaped protrusion.

[0022] Preferably, the inner cylinder is provided with a third strip-shaped protrusion, and the inner pusher is provided with a third recess for engaging with the third strip-shaped protrusion. The inner cylinder can drive the inner pusher to rotate by engaging with the third strip-shaped protrusion and the third recess.

[0023] Preferably, the inner locking mechanism includes a rod on the mounting base and a stop at one end of the rod away from the base. The inner pushing member is provided with a clearance hole, and the stop can pass through the clearance hole into the inner pushing member and be engaged with the inner pushing member by rotation.

[0024] Preferably, the inner pusher is further provided with a limiting protrusion around the clearance hole. When the stop is engaged with the clearance hole at the top of the inner pusher, the stop is limited by the limiting protrusion.

[0025] Preferably, the external locking mechanism includes a connecting block on the mounting base and a locking member disposed at one end of the connecting block away from the base. The external pushing member is provided with a locking hole, and the external pushing member can be rotated to engage or disengage the locking member with the locking hole.

[0026] This invention employs a dual-cavity independent linkage launch system. By rotating the outer cylinder, the outer pusher, inner cylinder, and inner pusher are sequentially linked, enabling automatic sequential unlocking of the outer and inner storage spaces. A single rotation operation can trigger two launch actions, improving operational continuity.

[0027] This utility model adopts a layered nested design of inner and outer containment spaces (the outer containment space surrounds the inner containment space), which supports the separate packaging and combination of colored strips and toys, expanding the diversity of entertainment effects.

[0028] This invention features inner and outer annular ribs supporting baffles to precisely position the projectile, ensuring that the elastic force of the elastic element is fully converted into effective thrust, thereby improving launch efficiency. Attached Figure Description

[0046] Figure 1 This is a schematic diagram of the structure of a fireworks launcher according to the present invention.

[0047] like Figures 1 to 10 As shown, a fireworks launcher includes a first launching section and a second launching section. The first launching section can be filled with confetti or toys, and the second launching section can also be filled with confetti or toys. The first launching section is located inside the second launching section. Both the first and second launching sections can be subjected to force to generate a force that pushes the confetti or toys out, so that the confetti or toys can be launched. The launcher can launch twice, and different items can be loaded for multiple launches. The product styles are diverse.

[0048] refer to Figure 1 , Figure 4 and Figure 5 The fireworks launcher includes a base 100, an inner elastic element 200, an inner pusher element 300, and an inner cylinder 400.

[0049] See Figures 4 to 8 The base 100 is provided with an inner locking mechanism 110. The inner pushing member 300 is installed on the base 100 and can be fixed on the base 100 through the inner locking mechanism 110. The inner elastic member 200 is installed between the inner pushing member 300 and the base 100. When the inner locking mechanism 110 locks the inner pushing member 300, the inner elastic member 200 is compressed by the inner pushing member 300. When the inner locking mechanism 110 and the inner pushing member 300 are unlocked, the inner pushing member 300 is pushed under the elastic force of the inner elastic member 200.

[0050] The inner cylinder 400 is rotatably mounted on the base 100. The inner cylinder 400 cannot move relative to the base 100 in the axial direction. The inner cylinder 400 is sleeved on the outer side of the inner pusher 300 on the base 100. When the inner pusher 300 is locked to the base 100 by the inner locking mechanism 110, its axial height is lower than the axial height of the inner cylinder 400. An internal storage space 500 for accommodating colored strips or toys can be formed between the side wall of the inner cylinder 400 and the inner pusher 300. When the inner pusher 300 is unlocked from the inner locking mechanism 110, the inner pusher 300 can push out the colored strips or toys in the internal storage space 500 under the action of the inner elastic member 200. This is the first launching part, which can be used to launch colored strips or toys.

[0051] Specifically, in this embodiment... Figure 6 , Figure 7 As shown, the inner pushing member 300 is a cylindrical structure with an open bottom, and the top of the inner pushing member 300 is provided with a clearance hole 310; the inner locking mechanism 110 on the base 100 includes a rod 111 connected to the base 100 and a stop 112 located at the end of the rod 111 away from the base 100. The size of the stop 112 is larger than the size of the rod 111, and the stop 112 is a strip structure whose shape is adapted to the clearance hole 310. It can extend out of the top of the inner pushing member 300 through the clearance hole 310. By rotating, the stop 112 can be engaged with the inner pushing member 300. The top of the inner pusher 300 allows the stop 112 to be engaged and locked with the inner pusher 300; the inner elastic member 200 is a spring with a diameter smaller than that of the inner pusher 300. The inner pusher 300 can be fitted onto the inner elastic member 200 and then locked onto the base 100 by the inner locking mechanism 110. The inner elastic member 200 can provide elastic force to the inner pusher 300; the inner cylinder 400 is a circular cylinder with both ends open, so that one end can be fitted onto the base 100 and located outside the inner pusher 300, while the other end can be used to launch colored strips or toys.

[0052] Preferably, a reinforcing rib 113 is provided between the rod 111 and the base 100 to prevent breakage between the rod 111 and the base 100.

[0053] Preferably, the inner pusher 300 is further provided with a limiting protrusion 330 around the clearance hole 310. When the stop 112 engages with the clearance hole 310 at the top of the inner pusher 300, the stop 112 is blocked by the limiting protrusion 330, preventing the stop 112 from rotating in the opposite direction and affecting the launch of the colored strips or toys.

[0054] Preferably, the inner side of the inner cylinder 400 is also provided with an inner annular rib 410. The inner annular rib 410 surrounds the inner wall of the inner cylinder 400 in the circumferential direction. When the inner pusher 300 is installed on the base 100, the inner annular rib 410 is located above the inner pusher 300. A baffle can be placed through the inner annular rib 410. The baffle is supported by the inner annular rib 410 inside the inner cylinder 400. A colored strip or a toy is then placed on the baffle. When the inner pusher 300 is unlocked, it strikes the baffle, pushing the colored strip or toy out.

[0055] Furthermore, the diameter of the inner annular rib 410 is larger than the diameter of the inner pusher 300, so that when the inner pusher 300 is acted upon by the inner elastic member 200, it is not blocked by the inner annular rib 410, and the inner pusher 300 can move smoothly within the inner cylinder 400 to push the colored strips or toys to launch.

[0056] The fireworks launcher also includes an outer cylinder 600, an outer elastic element 700, and an outer pushing element 800.

[0057] The base 100 is also provided with an external locking mechanism 120. The external pusher 800 is installed on the base 100 and locked and fixed by the external locking mechanism 120. The external elastic member 700 is installed between the external pusher 800 and the base 100. When the external locking mechanism 120 locks the external pusher 800, the external elastic member 700 is compressed. When the external locking mechanism 120 and the external pusher 800 are unlocked, the external pusher 800 can be pushed under the elastic force of the external elastic member 700.

[0058] When the outer pusher 800 is installed on the base 100, it is located outside the inner cylinder 400. The outer cylinder 600 is installed on the base 100 and fits around the outer pusher 800. The axial height of the outer cylinder 600 is higher than that of the outer pusher 800. An outer receiving space 900 for accommodating colored strips or toys is formed between the inner wall of the outer cylinder 600, the top of the outer pusher 800, and the outer wall of the inner cylinder 400. When the outer pusher 800 is unlocked from the outer locking mechanism 120, under the action of the outer elastic member 700, the outer pusher 800 pushes the colored strips or toys in the outer receiving space 900 to launch, which is the second launching part.

[0059] Specifically, in this embodiment, the outer pushing member 800 is a cylindrical structure with an open bottom. The top of the outer pushing member 800 is provided with a locking hole 810. The outer locking mechanism 120 on the base 100 includes a connecting block 121 connected to the base 100 and a locking member 122 located at the end of the connecting block 121 away from the base 100. The locking hole 810 specifically has a large portion 811 through which the locking member 122 can pass and a small portion 812 through which the locking member 122 cannot pass. The large portion 811 and the small portion 812 are connected at the top of the outer pusher 800 and distributed circumferentially. When the outer pusher 800 is installed on the base 100, the engaging member 122 of the outer locking mechanism 120 can extend through the large portion 811 and out of the top of the outer pusher 800. By rotating, the engaging member 122 can fall on the small portion 812, so that the engaging member 122 is locked on the top of the inner pusher 300, so that the base 100 can be used to engage and lock with the outer pusher 800.

[0060] The outer elastic element 700 is also a spring, with a diameter smaller than that of the outer pusher 800 but larger than that of the inner cylinder 400. The outer pusher 800 can be fitted onto the outer elastic element 700. When the outer locking mechanism 120 of the outer pusher 800 is locked onto the base 100, the outer elastic element 700 can provide elastic force to the outer pusher 800. The outer cylinder 600 is also a circular cylinder with both ends open, so that one end can be fitted onto the base 100 and located on the outer layer of the outer pusher 800, while the other end can be used to launch colored strips or toys.

[0061] Preferably, there are two outer locking mechanisms 120, which are distributed at 180 degrees on the base 100 and are arranged around the outer side of the inner locking mechanism 110.

[0062] Preferably, the outer cylinder 600 is rotatably mounted on the base 100 by means of threads.

[0063] Preferably, the outer pusher 800 has a through hole 820 in the middle, so that when it is installed on the base 100, both the inner pusher 300 and the inner cylinder 400 can pass through the through hole 820 to the outer pusher 800, so that the outer pusher 800 will not affect the launch of the first launcher.

[0064] It is understandable that the inner side of the outer cylinder 600 is also provided with an outer annular rib 620. The outer annular rib 620 surrounds the inner wall of the outer cylinder 600 in a circumferential direction. When the outer pusher 800 is installed on the base 100, the outer annular rib 620 is located above the outer pusher 800. A baffle can be placed inside the outer cylinder 600 through the outer annular rib 620. The baffle is supported by the outer annular rib 620 inside the outer cylinder 600. Then, colored strips or toys are placed on the baffle. When the outer pusher 800 is unlocked, it strikes the baffle and pushes the colored strips or toys out.

[0065] Preferably, the diameter of the outer annular rib 620 is larger than the diameter of the outer pusher 800, so that when the outer pusher 800 is acted upon by the inner elastic member 200, it is not blocked by the outer annular rib 620, and the outer pusher 800 can move smoothly within the outer cylinder 600 to push the colored strips or toys to launch.

[0066] Preferably, the inner side of the outer cylinder 600 is provided with a first strip-shaped protrusion 610 arranged in the axial direction for engaging with the outer pusher 800, so that the outer cylinder 600 can drive the outer pusher 800 to rotate, and when the outer pusher 800 pops out in the axial direction, it can be limited by the first strip-shaped protrusion 610. Specifically, the outer pusher 800 is provided with a first recessed notch 830 on its outer side. When the outer cylinder 600 is fitted onto the outer side of the outer pusher 800, the first strip-shaped protrusion 610 engages with the first recessed notch 830, so that the outer pusher 800 and the outer cylinder 600 are engaged.

[0067] Similarly, the inner cylinder 400 has a second strip-shaped protrusion 420 and a third strip-shaped protrusion 430 arranged along the axial direction on its outer and inner sides, respectively, for engaging with the outer pusher 800 and the inner pusher 300, so that the inner cylinder 400 can be driven by the outer pusher 800 and drive the inner pusher 300 to rotate. Specifically, the outer pusher 800 has a second recessed notch 840 on its inner side. When the outer pusher 800 is fitted onto the outer side of the inner cylinder 400, the second strip-shaped protrusion 420 engages with the second recessed notch 840, so that the inner cylinder 400 and the outer pusher 800 are engaged; the inner pusher 300 has a third recessed notch 320 on its outer side. When the inner cylinder 400 is fitted onto the outer side of the inner pusher 300, the third strip-shaped protrusion 430 engages with the third recessed notch 320, so that the inner pusher 300 and the inner cylinder 400 are engaged.

[0068] When in use, the user holds the outer cylinder 600 with his hand and rotates the outer cylinder 600, which rotates relative to the base 100.

[0069] When the outer cylinder 600 rotates, the first strip-shaped protrusion 610 drives the outer pusher 800 to rotate, which allows the outer pusher 800 to rotate relative to the outer locking mechanism 120 on the base 100, thus releasing the lock. Under the action of the outer elastic member 700, the outer pusher 800 pushes the colored strips or toys inside the outer cylinder 600 to launch. Moreover, the rotation of the outer pusher 800 can drive the inner cylinder 400 to rotate through the second recess 840 and the second strip-shaped protrusion 420. The rotation of the inner cylinder 400 then drives the inner pusher 300 to rotate through the third strip-shaped protrusion 430, which allows the inner pusher 300 to rotate relative to the inner locking mechanism 110 on the base 100, thus releasing the lock. Under the action of the inner elastic member 200, the inner pusher 300 pushes the colored strips or toys inside the inner cylinder 400 to launch.

[0070] It is understandable that the sequence in which the inner pusher 300 and the outer pusher 800 are released when the outer cylinder 600 rotates can be set as needed.

[0071] Preferably, when the outer cylinder 600 is rotated, the inner pusher 300 first releases from the inner locking mechanism 110, and the first launching part launches first. Then, the outer pusher 800 releases from the outer locking mechanism 120, and the second launching part launches.

[0072] Specifically, in this embodiment, refer to Figure 3 The angle at which the inner locking mechanism 110 and the inner pusher 300 release their locks is ∠a, which is approximately 90 degrees. The angle at which the outer locking mechanism 120 and the outer pusher 800 release their locks is ∠b. They share the same starting point of rotation, but ∠b is larger than ∠a, approximately 100 degrees. This ensures that when the outer cylinder 600 rotates, the inner locking mechanism 110 and the inner pusher 300 release their locks first, allowing the items in the inner storage space 500 to be launched first. Then, the outer locking mechanism 120 and the outer pusher 800 release their locks, allowing the items in the outer storage space 900 to be launched later. Alternatively, in some embodiments, by changing the length of the smaller portion 812 of the engaging hole 810, the angle at which the inner locking mechanism 110 needs to rotate to release the lock from the inner pusher 300 is adjusted to be larger than the angle at which the outer locking mechanism 120 needs to rotate to release the lock from the outer pusher 800. This allows the items in the outer storage space 900 to be launched before the items in the inner storage space 500.

[0073] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
