Description

Technical Field

[0001] This utility model relates to the field of fireworks tube assembly technology, and in particular to an assembly tool for combined fireworks tubes. Background Technology

[0002] A firework tube array is a combination structure formed by fixing multiple firework tubes in a specific arrangement on the same support frame. It can ignite each firework tube in a preset order, so that the firework propellant forms a continuous pattern, color or special effect when it is set off. When assembling a firework tube array, multiple firework tubes are usually placed in the combination frame, then a separator paper is placed on the row of firework tubes, glue is applied to the separator paper, and then another row of firework tubes is placed on it. Finally, the firework tube array is formed by combining multiple rows of firework tubes.

[0003] In the process of assembling firework tubes, a row of firework tubes is first placed in the assembly frame, a separator paper is placed on the row of firework tubes, glue is applied to the separator paper, and then another row of firework tubes is placed on top. The firework tubes are assembled by combining multiple rows of firework tubes to form a firework tube row. However, when placing a row of firework tubes on the separator paper, multiple firework tubes are usually picked up manually and placed on the separator paper at the same time. However, when picking up multiple firework tubes manually, there is a risk of picking up too many or too few, and multiple firework tubes are stacked up during the picking process. When placing multiple firework tubes on the separator paper, a separate stacking operation is required, which increases the workload of assembling firework tube rows. The ease of operation of assembling firework tube rows needs to be improved. Therefore, this application provides an assembly tool for assembling firework tube rows to meet the needs. Utility Model Content

[0004] This utility model provides an assembly tool for combined fireworks tube arrays to solve the problem that the ease of operation of assembling fireworks tube arrays needs to be improved.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An assembly tool for a combined fireworks tube array includes a mounting base. A plurality of positioning posts are connected to the side of the mounting base. The positioning posts are evenly distributed at intervals on the side of the mounting base. A fixing component is provided at one end of the positioning posts near the mounting base. The fixing component is used to install and fix the positioning posts on the side of the mounting base.

[0007] When assembling a row of firework tubes, multiple positioning posts are inserted into multiple firework tubes simultaneously, and the row of tubes is moved to the assembly area for assembly.

[0008] Preferably, the fixing component includes a locking block fixed to one end of the positioning post near the mounting base. The mounting base has a square groove on its side, the locking block is inserted into the square groove, and a screw is fixed to the side of the locking block. A nut is threaded onto the screw, and the nut presses against the side of the mounting base away from the positioning post.

[0009] Preferably, a connecting block is fixed to the side of the card block, the connecting block is fixed on the screw, and the connecting block is located in the square groove.

[0010] Preferably, the side of the connecting block is provided with an inclined guide surface, which is used to guide the connecting block when it is inserted into the square groove.

[0011] Preferably, the positioning post has a recessed portion on its circumferential surface, and the end of the positioning post away from the mounting base is curved.

[0012] Preferably, the side of the mounting base is provided with a separation component, which includes a magnetic strip embedded in one side of the mounting base corresponding to the positioning post. A push plate is magnetically attracted to the side of the magnetic strip. A through groove is opened on the push plate corresponding to the position of the positioning post. The positioning post is located in the through groove. A handle is fixed on the side of the push plate near the mounting base. The mounting base is located inside the handle.

[0013] Preferably, the top and bottom of the mounting base are both fixed with protrusions, which are used to provide force points when gripping the mounting base.

[0014] Preferably, the handle has a curved portion in the middle area, the curved portion corresponding to the protrusion, an extension portion is fixed on the opposite side of the curved portion, and a rubber pad is fixed on the top of the extension portion.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, by setting up mounting bases and positioning columns, multiple positioning columns are fixed on the same mounting base. When taking out firework tubes, multiple positioning columns are inserted into multiple firework tubes respectively to take out the specified number of firework tubes, and there will be no situation of taking too many or too few. At the same time, when placing the firework tubes on the divider paper, multiple positioning columns can position multiple firework tubes, so that multiple firework tubes can be directly placed on the divider paper in a row, without the need for subsequent individual stacking. This greatly reduces the operation steps in the process of arranging firework tubes and improves the operation convenience of arranging firework tubes.

[0017] By setting a recessed part on the positioning post, the contact area between the positioning post and the inner wall of the firework tube is reduced, thereby reducing the friction between the positioning post and the firework tube. When the positioning post is inserted into a row of firework tubes, it effectively prevents the firework tubes from shifting due to friction, ensuring that multiple firework tubes are positioned consistently on multiple positioning posts, which facilitates subsequent placement operations. At the same time, when multiple firework tubes are placed on the separator paper, and the positioning post needs to be pulled out of the firework tube, the reduced friction effectively prevents the firework tubes from moving with the positioning post, ensuring the consistent placement of the firework tubes on the separator paper.

[0018] By incorporating a curved section, when the positioning pin is inserted into the firework tube by holding the protrusion of the mounting base, the curved section on the handle contacts the bottom of the operator's arm. The cooperation between the protrusion and the curved section provides multi-point support, improving the operational stability of transferring the firework tube from the storage area to the assembly area. This prevents the entire device from slipping out of the hand at the protrusion position due to its own weight and the weight of multiple firework tubes, thereby improving the operational stability during the assembly of the firework tubes.

[0019] By setting up a push plate, after placing rows of firework tubes on the separator paper, hold the handle with one hand to make the push plate press against the end of the firework tube, and pull the mounting base with the other hand to pull the positioning post out of the firework tube. The push plate ensures that the rows of firework tubes will not move on the separator paper when the positioning post is pulled out of the firework tube, thus forcing the firework tubes to maintain a consistent position on the separator paper and ensuring that the ends of multiple firework tubes are aligned, laying the foundation for subsequent processing operations.

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0027] The assembly tool for a combined fireworks tube array provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] like Figures 1-5 As shown, an embodiment of the present invention provides an assembly tool for a combined firework tube array, including a mounting base 1. Multiple positioning posts 2 are connected to the side of the mounting base 1. The positioning posts 2 are hollow, which reduces the weight of the entire device and makes it easier to move the firework tubes. The multiple positioning posts 2 are evenly distributed on the side of the mounting base 1. A fixing component 4 is provided at one end of the positioning post 2 near the mounting base 1. The fixing component 4 is used to fix the positioning post 2 on the side of the mounting base 1.

[0029] When assembling the fireworks tube array, multiple positioning posts 2 are simultaneously inserted into multiple fireworks tubes, and the array is moved to the assembly area for assembly. The positioning posts 2 achieve one-to-one positioning by inserting into the fireworks tubes, allowing multiple fireworks tubes to be picked up at once. At the same time, the positioning posts 2 can limit the position of the fireworks tubes during the transfer process to prevent them from tipping over. The fixing component 4 can firmly fix the positioning posts 2 to the mounting base 1 to prevent the positioning posts 2 from loosening or falling off during the transfer process, ensuring the stable support and positioning of the fireworks tubes by the positioning posts 2, and guaranteeing the overall reliability of the assembly tool.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown in this embodiment, the fixing component 4 includes a locking block 6 fixed to one end of the positioning post 2 near the mounting base 1. A square groove 5 is provided on the side of the mounting base 1. The locking block 6 is inserted into the square groove 5. A screw rod 7 is fixed to the side of the locking block 6. A nut is threaded onto the screw rod 7. The nut presses against the side of the mounting base 1 away from the positioning post 2. The cooperation between the locking block 6 and the square groove 5 provides precise installation positioning for the positioning post 2, preventing the positioning post 2 from rotating or shifting on the mounting base 1. This ensures that the axes of multiple positioning posts 2 are parallel and the spacing is consistent, guaranteeing the accuracy when inserting the firework tubes. The threaded connection between the screw rod 7 and the nut can make the end of the positioning post 2 fit tightly against the mounting base 1 through the pressure generated by tightening the nut, thereby fixing the positioning post 2. At the same time, the threaded connection structure allows for flexible addition, reduction, or replacement of positioning posts 2 according to the number of firework tubes required, improving the versatility of the assembly tools and adapting to the assembly needs of different specifications of firework tubes.

[0031] like Figure 3 and Figure 5As shown in this embodiment, a connecting block 8 is fixed to the side of the locking block 6. The connecting block 8 is fixed to the screw 7 and is located in the square groove 5. The connecting block 8 connects the locking block 6 and the screw 7, which can enhance the connection strength between the locking block 6 and the screw 7, prevent the screw 7 from being subjected to long-term force and causing the connection with the locking block 6 to break, and extend the service life of the fixing component 4.

[0032] like Figure 5 As shown in this embodiment, the side of the connecting block 8 is provided with an inclined guide surface. The guide surface is used to guide the connecting block 8 when it is inserted into the square groove 5. The inclined guide surface has a smooth transition structure and can play a guiding and correcting role when the connecting block 8 is inserted into the square groove 5. Even if there is a slight misalignment between the connecting block 8 and the square groove 5, the guide surface can automatically guide the connecting block 8 into the square groove 5 through the inclined contact, avoiding jamming or collision between the connecting block 8 and the edge of the square groove 5, and reducing the installation difficulty of the positioning post 2.

[0033] like Figure 1 As shown in this embodiment, a recess 3 is provided on the circumferential surface of the positioning post 2. The end of the positioning post 2 away from the mounting base 1 is curved. The curved structure of the end of the positioning post 2 away from the mounting base 1 can prevent the sharp edge from scratching the inner wall of the firework tube when it is inserted. At the same time, the curved surface guides the positioning post 2 to smoothly enter the opening of the firework tube. Even if there is a slight deviation between the positioning post 2 and the opening of the firework tube, the curved surface can automatically correct the position, reducing the difficulty of insertion. The recess 3 can significantly reduce the contact area between the positioning post 2 and the inner wall of the firework tube, thereby reducing the frictional resistance between the two. When inserted, it can prevent the firework tube from shifting with the positioning post 2 due to excessive friction, ensuring the positioning consistency of multiple firework tubes on the positioning post 2. When pulled out, it can prevent the firework tube from being carried away from the preset placement position due to friction, ensuring the accuracy of the placement of the firework tube on the separator paper.

[0034] like Figure 1 , Figure 2 and Figure 4As shown in this embodiment, a separation component 10 is provided on the side of the mounting base 1. The separation component 10 includes a magnetic strip 16 embedded in one side of the mounting base 1 corresponding to the positioning post 2. A push plate 15 is magnetically attracted to the side of the magnetic strip 16. A through groove is opened on the push plate 15 corresponding to the position of the positioning post 2, and the positioning post 2 is located in the through groove. A handle 11 is fixed on the side of the push plate 15 near the mounting base 1. The mounting base 1 is located inside the handle 11. The magnetic attraction between the magnetic strip 16 and the push plate 15 can position the push plate 15 on the side of the mounting base 1 in the non-separated state, avoiding the push plate 15 shaking and interfering with the positioning. The column 2 is inserted into the firework tube. When separating, only external force needs to be applied to separate the push plate 15 from the magnet strip 16, which is convenient to operate. The through groove on the push plate 15 provides space for the positioning column 2 to pass through, ensuring that the push plate 15 does not interfere with the positioning column 2 when it moves. When the positioning column 2 is pulled out from the firework tube, the push plate 15 can abut against the end of the firework tube. The reverse thrust prevents the firework tube from moving with the positioning column 2, ensuring that the firework tube is accurately placed on the separator paper and that the ends of multiple firework tubes are aligned, laying the foundation for subsequent processes. The handle 11 provides a force point for the operator to easily hold and push the push plate 15.

[0035] like Figures 1-4 As shown in this embodiment, the top and bottom of the mounting base 1 are both fixed with protrusions 9. The protrusions 9 are used to provide a force point when gripping the mounting base 1. The protrusions 9 protrude from the surface of the mounting base 1, which can provide the operator with a clear and easy-to-grip force point, and prevent the tool from slipping when gripping. Especially when the tool carries multiple firework tubes and the weight increases, the protrusions 9 can enhance the grip stability.

[0036] like Figure 1 and Figure 2 As shown in this embodiment, the handle 11 has a bent portion 12 in the middle area, which corresponds to the protrusion 9. An extension portion 13 is fixed on the opposite side of the bent portion 12, and a rubber pad 14 is fixed on the top of the extension portion 13. The bent structure of the bent portion 12 is adapted to the contour of the bottom of the operator's arm. When the protrusion 9 is held, the bottom of the arm can naturally fit the bent portion 12, forming multi-point support with the protrusion 9. This disperses the pressure of the weight of the entire device and the firework tube on the hand, avoiding hand fatigue caused by long-term operation. At the same time, it prevents the entire weight from being concentrated at the protrusion 9 and slipping out of the hand. The extension portion 13 can extend the support range of the bent portion 12 and prevent the narrow width of the bent portion 12 from digging into the operator's arm. The rubber pad 14 is soft and elastic, which can increase the comfort of the arm in contact with the bent portion 12.

[0037] Working principle: Align the locking block 6 at the end of the positioning post 2 near the mounting base 1 with the square groove 5 on the side of the mounting base 1. The inclined guide surface of the connecting block 8 on the side of the locking block 6 will guide the connecting block 8 to be smoothly inserted into the square groove 5. Pass the screw 7 through the square groove 5 and screw the nut on the end of the screw 7 so that the nut is pressed tightly against the mounting base 1, so that the end of the positioning post 2 is tightly fitted with the mounting base 1 to achieve fixation. According to the required number of firework tubes, fix the corresponding number of positioning posts 2 evenly at intervals on the mounting base 1 to ensure accurate quantity when taking out firework tubes later.

[0038] When picking up a firework tube, the operator holds the protrusions 9 at the top and bottom of the mounting base 1. The protrusions 9 provide clear points of force application and are easy to grip. The multiple positioning posts 2 are aligned with the openings of the multiple firework tubes in the storage area. The curved design of the end of the positioning post 2 away from the mounting base 1 guides it to be smoothly inserted into the firework tube. At the same time, the recessed part 3 on the circumference of the positioning post 2 reduces the contact area with the inner wall of the firework tube, reduces the friction between the two, and prevents the firework tube from shifting due to friction during insertion. This ensures the consistent positioning of multiple firework tubes on the positioning post 2, so that the rubber pad 14 at the curved part 12 in the middle area of ​​the handle 11 contacts the bottom of the operator's arm. Through the multi-point support of the protrusions 9 and the curved part 12, the stability of the handheld device when transferring firework tubes is improved, and the situation of slipping out of the hand due to the weight of the device itself and the weight of the firework tube at the protrusions 9 is avoided.

[0039] After transferring the firework tube to the assembly area, it needs to be placed on the separator paper. Then, hold the handle 11 with one hand so that the push plate 15 is against the end of the firework tube away from the mounting base 1. Pull the mounting base 1 with the other hand to pull the positioning post 2 out of the firework tube. During this process, the magnetic strip 16 on the side of the mounting base 1 separates from the push plate 15. The abutting action of the push plate 15 can prevent the firework tube from moving with the positioning post 2, ensuring that the firework tubes are placed in the same position on the separator paper and that the ends of multiple firework tubes are aligned. This eliminates the need for subsequent individual stacking, reducing operation steps. At the same time, the recessed part 3 further reduces the friction when the positioning post 2 is pulled out of the firework tube, preventing the firework tube from shifting.

[0040] After the positioning post 2 is pulled out of the firework tube, pull the handle 11 to make the push plate 15 fit with the magnetic strip 16 on the side of the mounting base 1. The push plate 15 is magnetically fixed and can be used again later.

[0041] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
