Description

Technical Field

[0001] This utility model relates to the field of lantern frame technology, specifically to an assembled lantern frame structure. Background Technology

[0002] Lanterns are an ancient lighting and decorative device. They typically consist of a foldable or fixed-shape frame and a lampshade covering the frame, with a light source inside to provide illumination (especially for outdoor, portable, or decorative purposes), create ambiance, and carry significant cultural and festive symbolism.

[0003] A lantern mainly consists of a frame, lampshade, light source, and base. The frame is the core structure supporting the entire lantern's shape. It is usually foldable, flattened for storage or transport, and unfolded for use, maintaining its shape thanks to the frame's elasticity and supporting structure (commonly spherical or ellipsoidal). The lampshade covers the frame and is used for light transmission, wind protection, and decoration. It is made of various materials such as paper, silk, cloth, plastic, and glass, and often features patterns or text. The light source is the part inside the lantern that provides illumination. The handle / hanging rope is used for carrying or hanging the lantern. The base / top cap secures the frame, connects the handle, and sometimes holds the light source or counterweight.

[0004] The core and most challenging aspect of making traditional foldable lanterns lies in the frame, typically constructed from slender bamboo strips or highly elastic spring steel wire. These materials are characterized by good elasticity, toughness, and a certain level of strength. During processing, multiple bamboo strips or spring steel wires are individually bent by hand into specific arch shapes (usually approximately semi-circular or semi-elliptical). The ends of each strip are then fixed into corresponding holes or slots on the upper and lower plates. Once all the arches are correctly secured, they naturally bend towards the center, collectively forming a retractable spherical or ellipsoidal frame, similar to a birdcage. This is the "frame." Its elasticity comes from the inherent material elasticity of each arched strip (bamboo strip or steel wire).

[0005] The traditional lantern's dragon frame requires each arched strip to be produced, bent, and corrected individually during the manufacturing process. It also requires manual alignment and installation of each arched strip between the upper and lower plates. However, this assembly process is quite cumbersome, and the labor and time costs incurred are high, making it difficult to reduce the overall assembly and manufacturing cost of the dragon frame. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an assembled lantern frame structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an assembled lantern frame structure, comprising an upper plate and a lower plate, wherein a dragon frame is provided between the upper plate and the lower plate, the dragon frame comprising two connecting beams arranged vertically for being able to bend and deform when driven by external force, and a plurality of connecting ribs arranged between the two connecting beams and equidistantly, the two connecting beams and the plurality of connecting ribs being integrally formed, and connecting members being provided at the left and right ends of the two connecting beams for fixing the ends of the connecting beams after they are bent, and engaging ring grooves being provided on both the upper plate and the lower plate for the two connecting beams to respectively engage on the upper plate and the lower plate after the connecting members fix the ends of the connecting beams, the engaging ring grooves being in clearance fit with the connecting beams.

[0008] A further improvement is that a clearance opening is provided at the connection between each of the connecting ribs and the connecting beam. The clearance opening is used to allow the connecting ribs to avoid contact with the connecting beam when the connecting ribs are bent and deformed.

[0009] A further improvement is that the connector includes a left connecting block and a right connecting block respectively disposed at the left and right ends of the two connecting beams, a connecting opening opened on the left connecting block for the right connecting block to pass through, and a limiting member disposed between the left connecting block and the right connecting block for restricting the left and right movement of the right connecting block when the right connecting block passes through the connecting opening.

[0010] A further improvement is that the limiting element includes a limiting groove formed on the right connecting block and a limiting protrusion disposed on the left connecting block for the right connecting block to pass through the connecting opening and cooperate with the limiting groove to limit the left and right movement of the right connecting block.

[0011] The improvements are as follows: When the two connecting beams are bent and curled to bring their left and right ends into contact, forming a cylindrical shape with several connecting ribs, the right connecting block is pulled through the connecting opening, and the limiting protrusion engages with the limiting groove, thus restricting the right connecting block's left and right movement. This fixes both ends of the connecting beams, preventing the curled beams and ribs from unraveling due to the reaction force generated by the curling. When the curled keel frame needs to be disassembled, the right connecting block is pulled upwards through the connecting opening, allowing the curled beams and ribs to unravel. This facilitates the packaging and transportation of individual components, preventing deformation of the connecting ribs during transport and ensuring the lantern's normal unfolding. It also reduces space occupation during storage. After customer acceptance, customers can assemble the lantern frame using the tutorial for normal use. This not only improves the ease of disassembly and assembly of the lantern frame but also facilitates transportation and provides protection.

[0012] A further improvement is that the connector includes a left connecting block and a right connecting block respectively disposed at the left and right ends of the two connecting beams, and a T-shaped slot opened on the right connecting block. The left connecting block is a T-shaped block, and the T-shaped block and the T-shaped slot are fitted with a clearance.

[0013] A further improvement is that both the upper plate and the lower plate are provided with clearance slots to provide clearance space for the left and right connecting blocks when the two connecting beams are respectively engaged in the engagement ring grooves. The clearance slots are connected to the engagement ring grooves.

[0014] A further improvement is that the upper plate and the lower plate are provided with engagement openings in the clearance slots, the engagement openings are connected to the clearance slots, and the left connecting block is provided with engagement protrusions for engaging with the engagement openings when the left and right connecting blocks are in the clearance slots, so as to clamp the connecting beam in the engagement ring groove.

[0015] A further improvement is that the engaging protrusion is a right-angled triangular block, and the upper plate and the lower plate are provided with chamfered surfaces at the end of the clearance slot to facilitate the engaging protrusion engaging into the engaging opening.

[0016] The improvement has the following effects: When the curled connecting beam is inserted into the locking ring groove, the clearance slot provides clearance space for the left and right connecting blocks, ensuring that the connecting beam is not affected by the left and right connecting blocks when it is in the locking ring groove. When the left and right connecting blocks are inserted into the clearance slot, the locking protrusion engages with the locking opening to lock the connecting beam in the locking ring groove. The curled connecting beam can be locked to the upper and lower plate components without the need for adhesive, thus achieving the connection and fixation of the connecting beam to the upper and lower plate components, and facilitating the subsequent disassembly and assembly of the lantern frame.

[0017] A further improvement is that: both the upper plate and the lower plate are provided with a secondary latch, which is connected to the engagement ring groove; the upper plate and the lower plate are provided with a secondary opening located within the secondary latch, which is connected to the secondary latch; and the two connecting beams are provided with a secondary locking block for engaging with the secondary opening to secure the connecting beams in the engagement ring groove when the two connecting beams are respectively engaged in the engagement ring groove.

[0018] The improvement has the following effects: When the left and right connecting blocks are inserted into the clearance slots, the secondary locking block engages with the secondary opening to secure the connecting beam in the locking ring groove. This allows the rolled-up connecting beam to be secured to the upper and lower plate components without the need for adhesive bonding. In conjunction with the locking structure of the locking protrusion and the locking opening, the securing effect on the connecting beam is further improved, thus achieving the connection and fixation of the connecting beam to the upper and lower plate components. It also facilitates the subsequent assembly and disassembly of the lantern frame.

[0019] A further improvement is that a guide rod is provided on the lower plate, and a guide hole is provided on the upper plate for the guide rod to pass through, with the guide hole and the guide rod being clearance-fitted.

[0020] The improvement has the following effects: The guide rod and guide hole are used to guide the lifting direction of the upper plate as it moves closer to or further away from the lower plate, causing the keel frame to expand into a lantern shape or contract into a cylindrical shape. This prevents the upper plate from shifting and affecting the expansion and contraction of the keel frame. In addition, the guide rod provides lateral support to the keel frame in both expansion and contraction states, ensuring its stability.

[0021] A further improvement is that a positioning mechanism is provided between the guide rod and the upper plate to fix the upper plate to the guide rod so that the drapery remains in an open state when the upper plate moves closer to the lower plate to open the drapery.

[0022] A further improvement is that the positioning mechanism includes an inclined elastic piece disposed in the middle of the guide rod and a release deformation port opened in the middle of the guide rod and located on one side of the inclined elastic piece for the inclined elastic piece to deform toward the guide rod position.

[0023] The improvement is as follows: During the process of the upper plate moving closer to the lower plate to expand the keel frame and form the lantern, the guide hole of the upper plate will contact the inclined elastic plate. As the upper plate descends, it will press the inclined elastic plate to deform towards the release deformation port, generating elastic potential energy. When the inclined elastic plate passes through the guide hole, it releases its elastic potential energy and returns to its original position. The keel frame, due to its elasticity and toughness, also generates elastic potential energy during expansion, thus providing an upward reaction force to the upper plate. At this time, the upper plate abuts against the lower end of the inclined elastic plate, thereby restricting its upward movement and fixing it to the guide rod to keep the keel frame in an expanded state. When it is necessary to release the upper plate... When the upper plate is restricted, first press down on it to move the inclined elastic piece away from it. Then press the inclined elastic piece towards the release deformation port until it can pass through the guide hole. At this point, you can slightly release the pressure on the upper plate. The elastic potential energy of the keel frame will cause the upper plate to rise, allowing the inclined elastic piece to pass through the guide hole. This allows the keel frame to fold into a cylinder, easily releasing the restriction effect on the upper plate and making the keel frame fold into a cylinder for easy carrying and storage. This modular lantern frame structure not only improves the assembly efficiency and stability of the lantern but also greatly enhances the user experience.

[0024] A further improvement is that the inclined elastic sheet is provided with an engaging notch.

[0025] The improvement has the following effects: When the lower end of the inclined elastic plate abuts against the upper end of the upper plate, the locking notch ensures stable contact between the inclined elastic plate and the upper plate, thereby improving the stability and reliability of the entire structure. Simultaneously, the locking notch also makes it easier for users to manipulate the inclined elastic plate when the restriction effect needs to be lifted, causing it to deform and pass through the guide hole to achieve the folding of the keel frame.

[0026] A further improvement is that there are two guide rods, and two guide holes are provided on the upper plate.

[0027] A further improvement is that the upper ends of the two guide rods are provided with fasteners for fixing the upper ends of the two guide rods.

[0028] A further improvement is that the fixing frame includes a fixing plate, and the upper ends of the two guide rods are provided with fixing rods. The fixing plate has two fixing holes for the fixing rods to pass through. The diameter of the fixing holes is smaller than the diameter of the fixing rods but larger than the diameter of the fixing rods. The upper end of the fixing rods is provided with a locking head, and the upper end of the straight part of the locking head is an arc surface.

[0029] The improvement is as follows: When the fixing plate needs to fix the upper ends of the two guide rods, the two fixing holes are aligned with the locking heads at the upper ends of the two guide rods respectively, and the fixing plate is pressed down to squeeze the fixing holes and locking heads. Through the arc surface at the upper end of the locking head, the locking head is deformed and indented by the setting of the deformation notch, thereby generating elastic potential energy so that the locking head can pass through the fixing hole. After the locking head passes through the fixing hole, the locking head releases the elastic potential energy and resets. Since the diameter of the locking head is larger than the diameter of the fixing hole, and since the diameter of the fixing hole is smaller than the diameter of the fixing rod but larger than the diameter of the fixing rod, the connection end of the locking head with the guide rod and the fixing rod fixes the position of the fixing plate.

[0030] A further improvement is that the fixing plate has a locking protrusion located in the fixing hole.

[0031] The improvement has the following effects: After the engaging head passes through the fixing hole, the diameter of the uppermost part of the fixing hole is reduced by the engaging protrusion. When the orientation of the deformation notch aligns with the position of the engaging protrusion, the engaging protrusion improves the engaging head's locking effect on the fixing piece. When it is necessary to remove the fixing piece from the two engaging heads, simply rotate the guide rod slightly to align the arc surface of the engaging head with the engaging protrusion, and then pull the guide rod downward to press the arc surface of the engaging head against the engaging protrusion. The arc surface facilitates the deformation of the engaging head towards the deformation notch, thus facilitating the disengagement of the engaging head from the fixing piece and completing the quick disassembly of the lantern frame. In addition, the design of the engaging protrusion also enhances the stability of the lantern frame structure. At the same time, the process of integrally injection molding the engaging protrusion, fixing piece, and fixing hole not only simplifies the production process but also improves the overall aesthetics and structural strength of the product, making the lantern frame structure more robust and durable, and extending the lantern's service life.

[0032] A further improvement is that a guide hole is provided on the lower plate, and a limiting block is provided at the lower end of the guide rod, the diameter of which is larger than the diameter of the guide hole.

[0033] The improvement has the following effects: By opening guide holes on the lower plate, the guide rod can be easily disassembled and installed from the lower and upper plate components. During assembly, the rolled-up connecting beam is first inserted into the engagement ring grooves of the upper and lower plate components for fixation. Then, the guide rod is passed through the guide hole of the lower plate component from bottom to top until the lower end of the lower plate component abuts against the limiting block, and then the guide rod is passed through the guide hole of the upper plate component. If disassembly is required, the guide rod is pulled down to facilitate subsequent disassembly, transportation, or storage.

[0034] The beneficial effects of this utility model after adopting the above technical solution are as follows: When producing the keel frame, the connecting beam and several connecting ribs are integrally processed and formed. Then, the connecting beam is rolled up so that its two ends contact each other. Then, the two ends of the connecting beam are fixed by the connectors, so that the keel frame is cylindrical (or elliptical). Then, the two rolled connecting beams are inserted into the locking ring groove and installed between the upper plate and the lower plate by means of bonding, welding, hot melting or buckling. By combining the connecting beam and the connecting ribs, the production process of the traditional lantern keel frame is greatly simplified. The entire lantern frame can be quickly built by simply assembling the upper and lower plate and the keel frame. Compared with the production of the traditional keel frame, there is no need to carry out tedious bending, correction and alignment installation steps, thereby significantly reducing labor costs and time costs.

[0035] Further benefits: Furthermore, because the connecting beams and ribs are made of elastic or tough materials, the keel frame can bend and deform under external forces, further simplifying the assembly process and improving the adaptability and flexibility of the lantern frame. At the same time, the design of the connectors ensures that the connecting beams can be stably fixed together after bending, thereby guaranteeing the overall stability and safety of the lantern frame.

[0036] Further benefits: Moreover, the design of this modular lantern frame structure also takes into account the recyclability and environmental friendliness of the materials. Connecting beams, reinforcing ribs, and connectors can all be made of environmentally friendly materials, ensuring both the strength and stability of the lantern frame while conforming to modern environmental protection principles.

Detailed Implementation

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0041] See Figures 1 to 9As shown, the technical solution adopted in this specific embodiment is: an assembled lantern frame structure, including an upper plate 1 and a lower plate 2, with a dragon frame between the upper plate 1 and the lower plate 2. The dragon frame includes two connecting beams 3 arranged vertically for bending and deforming under external force, and a plurality of connecting ribs 4 arranged equidistantly between the two connecting beams 3. The two connecting beams 3 and the plurality of connecting ribs 4 are integrally formed. Connecting members are provided at the left and right ends of the two connecting beams 3 for fixing the ends of the connecting beams 3 after they are bent. Both the upper plate 1 and the lower plate 2 are provided with engaging ring grooves 5 for the two connecting beams 3 to be respectively engaged on the upper plate 1 and the lower plate 2 after the connecting members fix the ends of the connecting beams 3. The engaging ring grooves 5 are clearance-fitted with the connecting beams 3. The upper plate 1 and the lower plate 2 have the same structure and are symmetrically arranged when installed at the upper and lower ends of the dragon frame. The materials for the connecting beam 3 and connecting ribs 4 can be elastic, tough, or a combination thereof, such as tough engineering plastics (nylon, POM, TPE, etc.). Plastic materials can also be chosen, but choosing plastic materials results in poorer rebound and toughness, and sacrifices the ability to close the lantern frame, although the lantern frame can remain open once extended. Engineering plastics are preferred, and the connecting beam 3 and several connecting ribs 4 are integrally injection molded, reducing the production cost of the lantern frame. During use, users can flexibly adjust the assembled lantern frame structure according to actual needs. For example, by changing the number and spacing of the connecting ribs 4, the rigidity and supporting force of the lantern frame can be adjusted, thereby creating lanterns of different shapes and sizes to meet diverse usage requirements. Figure 3 As shown, the connecting beam 3 and several connecting ribs 4 are curled into a circular shape to form the lantern's frame structure. Figure 4 As shown, the engaging ring groove 5 is an annular recess formed on the upper plate 1 and the lower plate 2. The two ends of the coiled cylindrical keel frame are aligned with the engaging ring groove 5 and pushed in along the tangential direction until the connector enters the clearance groove 11.

[0042] Each of the connecting ribs 4 and the connecting beam 3 is provided with a clearance opening 5. The clearance opening 5 is used to allow the connecting ribs 4 and the connecting beam 3 to avoid contact when the connecting ribs 4 are bent and deformed.

[0043] The connector includes a left connecting block 6 and a right connecting block 7 respectively disposed at the left and right ends of the two connecting beams 3, a connecting opening 8 opened on the left connecting block 6 for the right connecting block 7 to pass through, and a limiting member disposed between the left connecting block 6 and the right connecting block 7 to restrict the left and right movement of the right connecting block 7 when the right connecting block 7 passes through the connecting opening 8.

[0044] The limiting components include a limiting groove 9 formed on the right connecting block 7 and a limiting protrusion 10 disposed on the left connecting block 6 for the right connecting block 7 to pass through the connecting through-hole 8, which cooperates with the limiting groove 9 to limit the left and right movement of the right connecting block 7. The left connecting block 6 and the right connecting block 7 are integrally injection molded with the connecting through-hole 8, the limiting groove 9, the limiting protrusion 10 and the connecting beam 3.

[0045] like Figure 9 As shown, the connector includes a left connecting block 6 and a right connecting block 7 respectively disposed at the left and right ends of the two connecting beams 3, and a T-shaped slot 29 formed on the right connecting block 7. The left connecting block 6 is a T-shaped locking block 30, which is clearance-fitted with the T-shaped slot 29. Alternatively, the T-shaped slot 29 can be configured as a slot similar in shape to a light bulb, in which case the left connecting block 6 can be configured as a similar shape and clearance-fitted with the slot. The connector can also be selected as an adhesive fixing part, whereby the left and right ends of the connecting beam 3 are adhesively or heat-fused together when they are in contact. Other fastening structures can also be selected for the connector, as long as they can satisfy the requirement of fixing the left and right ends of the connecting beam 3.

[0046] Both the upper plate 1 and the lower plate 2 are provided with clearance slots 11 for providing clearance space for the left connecting block 6 and the right connecting block 7 when the two connecting beams 3 are respectively locked in the locking ring groove 5. The clearance slots 11 are connected to the locking ring groove 5.

[0047] The upper plate 1 and the lower plate 2 are provided with engagement openings 12 located in the clearance slots 11. The engagement openings 12 are connected to the clearance slots. The left connecting block 6 is provided with engagement protrusions 13 for engaging with the engagement openings 12 when the left connecting block 6 and the right connecting block 7 are located in the clearance slots 11, so as to clamp the connecting beam 3 in the engagement ring groove 5.

[0048] The design of the engaging protrusion 13 ensures that the connecting beam 3 is securely fixed within the engaging ring groove 5 during assembly, preventing it from loosening. When the left connecting block 6 and the right connecting block 7 are positioned within the clearance slot 11, the engaging protrusion 13 automatically engages with the engaging opening 12, forming a stable connection structure. This design not only improves the stability of the lantern frame but also simplifies the assembly process, making the lantern frame assembly more convenient and faster.

[0049] The engaging protrusion 13 is a right-angled triangular block, and the upper plate 1 and the lower plate 2 are provided with a chamfered surface at the end of the avoidance slot 11 to facilitate the engaging protrusion 13 to be engaged into the engaging opening 12.

[0050] The design of the right-angled triangular block with the engaging protrusion 13 allows for a tighter locking effect when it engages with the engaging opening 12, further enhancing the stability of the connection. The chamfered surface cleverly solves the resistance problem during the engagement process of the protrusion 13, making the assembly process smoother and easily completed without excessive manual operation.

[0051] Furthermore, the design of the avoidance slot 11 fully considers the maintenance needs of the lantern frame during long-term use. Since the connecting beam 3 is fixed by snap-fit ​​rather than adhesive, users can easily disassemble the connecting beam 3 when cleaning, repairing, or replacing parts of the lantern frame, without worrying about damage to parts or difficulty in separation caused by adhesive. This design not only improves the practicality of the lantern frame but also extends its service life, bringing greater convenience to users.

[0052] Both the upper plate 1 and the lower plate 2 are provided with a secondary latch 14, which is connected to the engagement ring groove 5. The upper plate 1 and the lower plate 2 are provided with a secondary opening 15 located in the secondary latch 14, which is connected to the secondary latch 14. The two connecting crossbeams 3 are provided with a secondary locking block 16 for engaging with the secondary opening 15 to lock the connecting crossbeams 3 in the engagement ring groove 5 when the two connecting crossbeams 3 are respectively locked in the engagement ring groove 5. The structure of the secondary buckle and secondary opening 15 can be the same as that of the clearance slot 11 and the engagement opening 12. In this case, the structure of the secondary locking block 16 is the same as that of the engagement protrusion 13. Furthermore, the position of the secondary locking port 14 on the upper plate 1 and lower plate 2 can be selected to correspond to the position of the clearance slot 11 (the two positions are symmetrical). The secondary locking block 16 is positioned in the middle of the connecting beam 3. This selection allows the user to freely choose one of the locking ports (clearance slot 11 or secondary locking port 14) on the left connecting block 6 and right connecting block 7 when engaging the connecting beam 3 into the engagement ring groove 5, without needing to find the corresponding engagement position. The secondary locking block 16 can also engage with one of the openings (engagement opening 12 or secondary opening 15), eliminating concerns about mismatched engagement positions. The shape of the secondary locking block 16 is as follows: Figure 1 , Figure 3 , Figure 4 As shown, it can also be configured to have the same structure as the engaging protrusion 13. The secondary bayonet 14, secondary opening 15, and secondary bayonet block 16 are integrally formed with the connecting crossbeam 3.

[0053] The lower plate 2 is provided with a guide rod 17, and the upper plate 1 is provided with a guide hole 18 for the guide rod 17 to pass through. The guide hole 18 and the guide rod 17 are fitted with a clearance.

[0054] The lower end of the guide rod 17 is fixedly connected to the bottom center of the lower plate 2, while the guide hole 18 is located at the top center of the upper plate 1, ensuring that the guide rod 17 can pass smoothly through the guide hole 18. The outer surface of the guide rod 17 is smooth, and the inner wall of the guide hole 18 is also smooth to reduce frictional resistance between them, allowing the upper plate 1 to move smoothly during lifting and lowering. At the same time, the gap between the guide rod 17 and the guide hole 18 is moderate, neither too tight to cause difficulty in movement, nor too loose to cause excessive swaying of the upper plate 1 during lifting and lowering. This design not only ensures the stability of the upper plate 1 during lifting and lowering but also improves the reliability and durability of the entire lantern frame structure.

[0055] A positioning mechanism is provided between the guide rod 17 and the upper plate 1 to fix the upper plate 1 on the guide rod 17 so that the dragon frame remains in an open state when the upper plate 1 moves closer to the lower plate 2 to open the dragon frame and form a lantern.

[0056] The positioning mechanism includes an inclined elastic piece 19 disposed in the middle of the guide rod 17 and a release deformation port 20 opened in the middle of the guide rod 17 and located on one side of the inclined elastic part for the inclined elastic piece 19 to deform towards the guide rod 17.

[0057] like Figure 5 As shown, the inclined elastic piece is gradually tilted outward from top to bottom so as not to affect the descent effect of the upper plate 1 when it descends. The inclined elastic piece 19 is provided with a locking notch 21.

[0058] There are two guide rods 17, and two guide holes 18 are formed on the upper plate 1. When only one guide rod 17 is selected, the guide rod 17 is located at the middle position between the lower plate 2 and the upper plate 1. In this application, it is preferred that there are two guide rods 17, and the two guide rods 17 are symmetrically arranged.

[0059] The upper ends of the two guide rods 17 are provided with fasteners for fixing the upper ends of the two guide rods 17.

[0060] The fixing frame includes a fixing plate 22, and fixing rods 23 are provided at the upper ends of the two guide rods 17. The fixing plate 22 has two fixing holes 24 for the fixing rods 23 to pass through. The diameter of the fixing holes 24 is smaller than the diameter of the fixing rods but larger than the diameter of the fixing rods 23. The upper end of the fixing rods 23 has a locking head 25, the diameter of which is larger than the diameter of the fixing holes 24. Deformation notches 26 are provided on both the locking head 25 and the fixing rods 23. The upper end of the locking head 25 is an arc surface. Figure 5As shown, the engaging head 25 is an arc-shaped head, and the length of the fixing rod 23 is slightly greater than the height of the fixing piece 22. The deformation notch 26 is longitudinally opened on the engaging head 25 and the guide rod 17. The deformation notch 26 divides the upper end of the engaging head 25 into two parts. The deformation notch 26 allows the engaging heads 25 to come close to each other and deform, making it easier for the engaging head 25 to pass through the fixing hole 24.

[0061] The fixing piece 22 has an engaging protrusion 27 located in the fixing hole 24. There can be one or two engaging protrusions 27; when two are used, they are symmetrically arranged, with a protrusion distance between them of 0.1-0.7 mm. The engaging protrusion 27 is integrally injection molded with the fixing piece 22 and the fixing hole 24, and is located at the uppermost position of the fixing hole 24, with a thickness of 0.1-0.7 mm.

[0062] The lower plate 2 has a guide hole 18, and the lower end of the guide rod 17 is provided with a limiting block 28, the diameter of which is larger than the diameter of the guide hole 18. When the lower plate 2 does not have a guide hole 18, regardless of whether the guide rod 17 is one located in the middle or two symmetrically arranged, the lower end of the guide rod 17 is fixedly mounted on the lower plate 2. This fixing can be achieved by integral injection molding with the lower plate 2 or by welding or bonding after separate production. Figure 5 As shown, a locking rib is provided on the lower periphery of the guide rod 17. The locking rib is used to engage the guide rod 17 with the guide hole 18 of the lower plate 2, and after the lower end of the lower plate 2 abuts against the limiting block 28, the locking rib will clamp the guide rod 17 in the guide hole 18 of the lower plate 2 to increase the stability of the guide rod 17 and the lower plate 2 after installation.

[0063] The working principle of this utility model is as follows: During the production of the keel frame, the connecting beam 3 and several connecting ribs 4 are integrally formed. Then, the connecting beam 3 is rolled up so that its two ends contact each other. The right connecting block 7 is pulled through the connecting through-hole 8, and the limiting protrusion 10 cooperates with the limiting groove 9, thereby restricting the left and right movement of the right connecting block 7. This fixes the two ends of the connecting beam 3, preventing the rolled connecting beam 3 and connecting ribs 4 from spreading out due to the reaction force generated by the rolling. This makes the keel frame form a cylindrical (or elliptical) shape. Finally, two rolled connecting beams 3 are inserted and locked together. In the annular groove 5, the clearance slot 11 provides clearance space for the left connecting block 6 and the right connecting block 7, ensuring that the connecting beam 3 is not affected by the arrangement of the left connecting block 6 and the right connecting block 7 when it is located in the engaging annular groove 5. When the left connecting block 6 and the right connecting block 7 are inserted into the clearance slot 11, the engaging protrusion 13 engages with the engaging opening 12 to engage and engage, thereby securing the connecting beam 3 in the engaging annular groove 5. Furthermore, the secondary engaging block 16 engages with the secondary opening 15 to engage and engage, thus securing the connecting beam 3 in the engaging annular groove 5. This allows for winding without the need for adhesive bonding. The connecting beam 3 after bending is clamped to the upper plate 1 and the lower plate 2 to achieve the connection and fixation between the connecting beam 3 and the upper plate 1 and the lower plate 2. Then, the guide rod 17 is passed from bottom to top through the guide hole 18 of the lower plate 2 until the lower end of the lower plate 2 abuts against the limiting block 28. Then, the guide rod 17 is passed through the guide hole 18 of the upper plate 1. The two fixing holes 24 are aligned with the locking heads 25 at the upper ends of the two guide rods 17 respectively, and the fixing piece 22 is pressed down to make the fixing holes 24 and the locking heads 25 squeeze together. Through the arc surface at the upper end of the locking head 25, the locking head... Part 25 generates a deformation indentation through the deformation notch 26, thereby generating elastic potential energy so that the engaging head 25 can pass through the fixing hole 24. After the engaging head 25 passes through the fixing hole, the engaging head 25 releases elastic potential energy and resets. Since the diameter of the engaging head 25 is larger than the diameter of the fixing hole 24, and since the diameter of the fixing hole 24 is smaller than the diameter of the fixing rod but larger than the diameter of the fixing rod 23, the connecting end of the engaging head 25 with the guide rod 17 and the fixing rod 23 fixes the position of the fixing piece 22, thus completing the assembly process of the lantern frame. As the upper plate 1 moves closer to the lower plate 2, causing the keel frame to expand and form a lantern, the guide hole 18 of the upper plate 1 contacts the inclined elastic plate 19. As the upper plate 1 descends, it presses the inclined elastic plate 19 towards the release deformation port 20, generating elastic potential energy. Once the inclined elastic plate 19 passes through the guide hole 18, it releases its elastic potential energy and resets. Because the keel frame possesses elasticity and toughness, it also generates elastic potential energy during expansion, thus providing an upward reaction force to the upper plate 1. At this point, the upper plate 1 abuts against the lower end of the inclined elastic plate 19, thereby restricting its upward movement and fixing it to the guide rod 17 to keep the keel frame in an expanded state. When it is necessary to release the upper plate... When the upper plate 1 is restricted, first press down on the upper plate 1 to move the inclined elastic piece 19 away from the upper plate 1 by a certain distance. Then press the inclined elastic piece 19 to deform in the direction of the release deformation port 20 until the inclined elastic piece 19 can pass through the guide hole 18. At this time, the hand can slightly release the pressure on the upper plate 1. Using the elastic potential energy of the keel frame, the upper plate 1 will rise, allowing the inclined elastic piece 19 to pass through the guide hole 18, so that the keel frame can be folded up to form a cylinder. The restriction effect on the upper plate 1 can be easily released, and the keel frame can be folded up to form a cylinder, which is convenient for carrying and storage. This modular lantern frame structure design not only improves the assembly efficiency and stability of the lantern, but also greatly enhances the user experience. By combining the connecting beam 3 and the connecting rib 4, the production process of the traditional lantern dragon frame is greatly simplified. The entire lantern frame can be quickly assembled by simply assembling the upper and lower plate parts 2 with the dragon frame. Compared with the production of the traditional dragon frame, there is no need for tedious bending, correction and alignment installation steps, which significantly reduces labor and time costs.
