Description

Technical Field

[0001] The present invention relates to the technical field of lantern frames, and in particular to an assembled lantern frame structure. Background Art

[0002] Lanterns are ancient lighting and decorative devices. They typically consist of a foldable or fixed frame covered by a lampshade, which houses a light source. Lanterns are used to provide illumination (especially for outdoor, portable, or decorative purposes) and create atmosphere, holding significant cultural and festive symbolism.

[0003] A lantern primarily consists of a frame, shade, light source, and base. The frame is the core structure that supports the lantern's shape. It's typically foldable, flattening for storage or transport. When in use, it unfolds, relying on the frame's elasticity and support structure to maintain its shape (commonly spherical or ellipsoidal). The shade covers the frame, providing light transmission, wind protection, and decorative effects. Made from a variety of materials, including paper, silk, cloth, plastic, and glass, it often features designs or text. The light source is the internal portion of the lantern that provides illumination. The handle / hanging rope is used to carry or hang the lantern. The base / top secures the frame, connects to the handle, and sometimes houses the light source or serves as a counterweight.

[0004] The core and most challenging aspect of traditional foldable lantern production lies in the keel frame, typically made from slender bamboo strips or highly elastic spring steel wire. These materials' key properties are excellent elasticity, toughness, and strength. During processing, multiple bamboo strips or spring steel wire are individually hand-bent into a specific arched shape (usually approximately semicircular or semi-elliptical). The ends of each strip are then secured to corresponding holes or slots in the upper and lower plates. Once all the arches are properly secured to the upper and lower plates, they naturally bend toward the center, forming a retractable spherical or ellipsoidal frame similar to a birdcage. This is the keel frame. Its elasticity comes from the inherent elasticity of each individual strip (bamboo strip or steel wire).

[0005] During the production process of the traditional lantern keel frame, each arch bar needs to be produced, bent, and corrected separately. Each arch bar also needs to be manually aligned and fixed between the upper and lower plates. However, this assembly process is relatively cumbersome, and the labor and time costs incurred in production are high, making it difficult to reduce the overall assembly and production costs of the keel frame. Summary of the Invention

[0006] The purpose of the present invention is to provide an assembled lantern frame structure in view of the defects and shortcomings of the prior art.

[0007] To achieve the above-mentioned object, the present invention adopts the following technical solution: an assembled lantern frame structure, comprising an upper plate and a lower plate, a keel frame is arranged between the upper plate and the lower plate, the keel frame comprises two connecting beams arranged above and below for curling and deforming when driven by external force, a plurality of connecting ribs arranged between the two connecting beams and equidistantly arranged, the two connecting beams and the plurality of connecting ribs are integrally formed, the left and right ends of the two connecting beams are provided with connecting members for fixing the two ends of the connecting beams after the connecting beams are curled, the upper plate and the lower plate are both provided with snap ring grooves for respectively clamping the two connecting beams on the upper plate and the lower plate after the connecting members fix the two ends of the connecting beams, and the snap ring grooves are clearance-matched with the connecting beams; A secondary snap-in is provided on both the upper plate and the lower plate, and the secondary snap-in is communicated with the snap-in ring groove. A secondary opening is provided on the upper plate and the lower plate in the secondary snap-in, and the secondary opening is communicated with the secondary snap-in. A secondary clamping block is provided on the two connecting beams for clamping with the secondary opening to clamp the connecting beams in the snap-in ring groove when the two connecting beams are respectively clamped in the snap-in ring groove.

[0008] The effect of this improvement is: when the left connecting block and the right connecting block are inserted into the avoidance groove, the auxiliary clamping block is clamped into the auxiliary opening for engagement, so that the connecting beam is clamped in the clamping ring groove, and the curled connecting beam can be clamped to the upper plate and the lower plate without bonding. In cooperation with the clamping structure of the clamping protrusion and the clamping opening, the clamping effect of the connecting beam can be further improved to achieve connection and fixation of the connecting beam to the upper plate and the lower plate, and facilitate subsequent disassembly and assembly of the lantern frame.

[0009] A further improvement is that a clearance opening is provided at the connection between each connecting rib and the connecting beam, and the clearance opening is used to allow the connecting rib and the connecting beam to avoid contact when the connecting rib is bent and deformed.

[0010] Further improvements are: the connecting member includes a left connecting block and a right connecting block respectively arranged at the left and right ends of the two connecting beams, a connecting through-hole opened on the left connecting block for the right connecting block to pass through, and a limiting member arranged between the left connecting block and the right connecting block for limiting the left and right movement of the right connecting block when the right connecting block passes through the connecting through-hole.

[0011] A further improvement is that the limiting member includes a limiting groove opened on the right connecting block, and a limiting protrusion arranged on the left connecting block for passing through the connecting opening when the right connecting block passes through the limiting groove to limit the left and right movement of the right connecting block.

[0012] The effect of this improvement is: when the two connecting beams are bent to curl the left and right ends of the connecting beams so that several connecting ribs form a cylindrical shape, the right connecting block is pulled through the connecting through-hole, and the limiting protrusion is matched with the limiting groove, thereby limiting the left and right movement of the right connecting block, so as to fix the two ends of the connecting beam, and prevent the curled connecting beams and connecting ribs from being scattered due to the reaction force generated by the curling; when the curled keel frame needs to be disassembled, the right connecting block is pulled upward and pulled out of the connecting through-hole, so that the curled connecting beams and connecting ribs can be scattered, which can facilitate the packaging and transportation of individual components, prevent the cylindrical keel frame from being compressed and deformed during transportation, thereby affecting the normal unfolding of the lantern, or reduce the space occupied during storage, and after the customer accepts it, the customer can assemble it through the tutorial and use it normally, which not only realizes the convenience of disassembly and assembly of the lantern frame, but also facilitates the disassembly and transportation of the lantern frame, and plays a protective role.

[0013] A further improvement is that the connecting piece includes a left connecting block and a right connecting block respectively arranged 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 is clearance-matched with the T-shaped slot.

[0014] A further improvement is that both the upper plate and the lower plate are provided with avoidance grooves for providing avoidance space for the left connecting block and the right connecting block when the two connecting beams are respectively clamped in the clamping ring grooves, and the avoidance grooves are connected to the clamping ring grooves.

[0015] A further improvement is that: a snap-fit ​​opening is provided on the upper plate and the lower plate in the avoidance groove, the snap-fit ​​opening is communicated with the avoidance groove, and the left connecting block is provided with a snap-fit ​​protrusion for engaging with the snap-fit ​​opening when the left connecting block and the right connecting block are avoided in the avoidance groove, so as to clamp the connecting beam in the snap-fit ​​ring groove.

[0016] A further improvement is that the engaging protrusion is a right-angled triangle block, and the upper plate and the lower plate are provided with chamfered surfaces at the ends where the slot is avoided, which facilitate the engaging protrusion to be engaged in the engaging opening.

[0017] The effect of this improvement: when the curled connecting beam is inserted into the snap ring groove, the avoidance groove is set to provide avoidance space for the left connecting block and the right connecting block, so that when the connecting beam is in the snap ring groove, the normal assembly will not be affected by the setting of the left connecting block and the right connecting block. When the left connecting block and the right connecting block are inserted into the avoidance groove, the snapping protrusion is inserted into the snap opening for snap fit to clamp the connecting beam in the snap ring groove. The curled connecting beam can be clamped to the upper and lower discs without bonding to achieve connection and fixation of the connecting beam to the upper and lower discs, and it is convenient for subsequent disassembly and assembly of the lantern frame.

[0018] A further improvement is that: a guide rod is provided on the lower disc, and a guide hole for the guide rod to pass through is opened on the upper disc, and the guide hole and the guide rod are clearance-matched.

[0019] The effect of this improvement: the guide rod and the guide hole are used to guide the lifting direction of the upper disk when the upper disk moves closer to or away from the lower disk, causing the keel frame to expand to form a lantern or collapse to form a cylinder, so as to prevent the lifting and lowering deviation of the upper disk from affecting the expansion and collapse state of the keel frame, and the setting of the guide rod can provide lateral support to the keel frame in the expanded and collapsed state, so that the keel frame in the expanded and collapsed state can maintain a stable state.

[0020] A further improvement is that a positioning mechanism is provided between the guide rod and the upper chuck for fixing the upper chuck on the guide rod to keep the keel frame in an expanded state when the upper plate member approaches the lower plate member to expand the keel frame to form a lantern.

[0021] A further improvement is that the positioning mechanism includes an inclined elastic piece arranged in the middle of the guide rod, and a release deformation opening opened in the middle of the guide rod and located on one side of the inclined elastic part for allowing the inclined elastic piece to deform toward the guide rod position.

[0022] The effect of this improvement: in the process of the upper plate member approaching the lower plate member to expand the keel frame to form a lantern, the guide hole of the upper plate member will contact the inclined elastic piece. As the upper plate member descends, the inclined elastic piece will be pressed to deform in the direction of the deformation release opening to generate elastic potential energy. When the inclined elastic piece passes through the guide hole, the inclined elastic piece releases the elastic potential energy and resets. The keel frame also generates elastic potential energy when it is expanded due to its elasticity and toughness, so it will provide an upward reaction force to the upper plate member. At this time, the upper plate member abuts against the lower end of the inclined elastic piece, thereby limiting the upward movement of the upper plate member, so as to fix the upper chuck on the guide rod to keep the keel frame in the expanded state; when it is necessary to release the upper chuck When the limiting effect of the disk is reached, first press down the upper disk to move the inclined elastic piece away from the upper disk for a distance, and then press the inclined elastic piece to deform in the direction of the deformation release port until the inclined elastic piece can pass through the guide hole. At this time, the hand can slightly release the downward pressure on the upper disk, and use the elastic potential energy of the keel frame to make the upper disk rise, so that the inclined elastic piece can pass through the guide hole, so that the keel frame can be folded into a cylinder, which can easily remove the limiting effect of the upper chuck and allow the keel frame to be folded into a cylinder, which is easy to carry and store. The design of this assembled lantern frame structure not only improves the assembly efficiency and stability of the lantern, but also greatly enhances the user experience.

[0023] A further improvement is that: the inclined elastic piece is provided with a snap-fitting notch.

[0024] The effect of this improvement is that when the lower end of the inclined elastic piece abuts the upper end of the upper disc, the provision of the engaging notch allows the lower end of the inclined elastic piece to abut the upper end of the upper disc, ensuring that the inclined elastic piece can stably abut the upper disc, thereby improving the stability and reliability of the entire structure. Furthermore, the provision of the engaging notch also makes it easier for the user to manipulate the inclined elastic piece when the restriction effect needs to be released, causing it to deform and pass through the guide hole to achieve the retraction of the keel frame.

[0025] A further improvement is that: there are two guide rods, and two guide holes are provided on the upper disk.

[0026] A further improvement is that: the upper ends of the two guide rods are provided with fixing pieces for fixing the upper ends of the two guide rods.

[0027] Further improvements are: the fixing frame includes a fixing plate, the upper ends of the two guide rods are provided with a fixing through rod, the fixing plate is provided with two fixing through holes for the fixing through rod to pass through, the diameter of the fixing through holes is smaller than the diameter of the fixing rod and larger than the diameter of the fixing through rod, the upper end of the fixing through rod is provided with a locking head, and the upper end of the straight part of the locking head is a circular arc surface.

[0028] The effect of this improvement is: when the fixing plate needs to fix the upper ends of the two guide rods, the two fixing through-holes are respectively aligned with the locking heads at the upper ends of the two guide rods, and the fixing plate is pressed down to squeeze the fixing through-holes and the locking heads. The arc surface at the upper end of the locking head allows the locking head to produce a deformation depression through the setting of the deformation notch, thereby generating elastic potential energy, so that the locking head can pass through the fixing through-hole. When the locking head passes through the fixing through-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 through-hole, and since the diameter of the fixing through-hole is smaller than the diameter of the fixing rod and larger than the diameter of the fixing through-rod, the connecting end of the locking head, the guide rod and the fixing through-rod fixes the position of the fixing plate.

[0029] A further improvement is that a locking protrusion is provided in the fixing through hole on the fixing plate.

[0030] The improvement has the following advantages: After the locking head passes through the fixing hole, the locking protrusion reduces the diameter of the uppermost end of the fixing hole. When the deformation notch is aligned with the locking protrusion, the locking protrusion improves the locking head's ability to restrict the fixing plate. To remove the fixing plate from the two locking heads, simply rotate the guide rod slightly to align the arc surface of the locking head with the locking protrusion. Then, pull the guide rod downward to squeeze the arc surface of the locking head against the locking protrusion. The arc surface facilitates the deformation of the locking head toward the deformation notch, thus facilitating the release of the locking head from the fixing plate and completing the quick disassembly of the lantern frame. Furthermore, the design of the locking protrusion enhances the structural stability of the lantern frame. Furthermore, the integrated injection molding process of the locking protrusion, fixing plate, and fixing perforation not only simplifies the production process but also improves the overall aesthetics and structural strength of the product, making the lantern frame more durable and extending the life of the lantern.

[0031] 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, wherein the diameter of the limiting block is larger than the diameter of the guide hole.

[0032] The effect of this improvement is that by opening a guide hole on the lower disc, the guide rod can be easily disassembled and installed from the lower disc and the upper disc. During assembly, the curled connecting beam is first installed into the snap ring grooves of the upper disc and the lower disc for fixation, and then the guide rod is passed from bottom to top through the guide hole of the lower disc until the lower end of the lower disc abuts against the limiting block, and then the guide rod is passed through the guide hole of the upper disc; if disassembly is required, the guide rod is pulled out downward, thereby pulling out the guide rod for subsequent disassembly, transportation or storage.

[0033] After adopting the above technical scheme, the beneficial effects of the present invention are as follows: when producing the keel frame, the connecting beam and several connecting ribs are integrally processed and formed, and then the connecting beam is curled so that its two ends are in contact, and then the two ends of the connecting beam are fixed by connecting parts to make the keel frame into a cylindrical (or elliptical) shape, and then the two curled connecting beams are inserted into the snap ring groove, and installed between the upper plate and the lower plate by bonding, welding, hot melting or snapping. Through the combination of connecting beams and connecting ribs, the production process of the traditional lantern keel frame is greatly simplified. It only takes a simple assembly of the upper and lower plates with the keel frame to quickly complete the construction of the entire lantern frame. Compared with the production of traditional keel frames, there is no need to perform tedious bending, correction and alignment installation steps, thereby significantly reducing labor costs and time costs.

[0034] Further Benefits: Furthermore, because the connecting beams and ribs are made of elastic or ductile materials, the keel frame can bend and deform when subjected to external forces, further simplifying the assembly process and improving the adaptability and flexibility of the lantern frame. Furthermore, the design of the connectors ensures that the connecting beams remain stably fixed together after being bent, thereby ensuring the overall stability and safety of the lantern frame.

[0035] Further benefits: The design of the assembled lantern frame structure also takes into account the recyclability and environmental friendliness of the materials. The connecting beams, connecting ribs, and connecting parts are all made of environmentally friendly materials, which not only ensures the strength and stability of the lantern frame, but also conforms to the environmental protection concept of modern society.

DETAILED DESCRIPTION

[0039] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0040] 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, a keel frame is arranged between the upper plate 1 and the lower plate 2, the keel frame includes two connecting beams 3 arranged upper and lower for curling and deforming when driven by external force, and a plurality of connecting ribs 4 arranged between the two connecting beams 3 and equidistantly arranged. The two connecting beams 3 and the plurality of connecting ribs 4 are integrally formed, and the left and right ends of the two connecting beams 3 are provided with connecting members for fixing the two ends of the connecting beams 3 after the connecting beams 3 are curled. The upper plate 1 and the lower plate 2 are both provided with a snap ring groove 5 for the two connecting beams 3 to be respectively clamped on the upper plate 1 and the lower plate 2 after the connecting members fix the two ends of the connecting beams 3. The snap ring groove 5 is in a clearance fit with the connecting beams 3. The upper plate 1 and the lower plate 2 have the same structure, and the two are symmetrically arranged when installed at the upper and lower ends of the keel frame. The materials of the connecting beams 3 and the connecting ribs 4 can be made of elastic or tough materials or a combination thereof, such as tough engineering plastics (nylon, POM, TPE, etc.). Plastic materials can also be selected, but the rebound effect and toughness deviation will be affected after selecting plastic materials. After selecting plastic materials, the folded state of the lantern frame will be abandoned, but the lantern frame can remain in the expanded state after it is expanded. It is preferred to select engineering plastics, and the connecting beams 3 and several connecting ribs 4 are processed and formed by integral injection molding to reduce the production cost of the keel frame. During use, users can also 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 hardness and supporting force of the lantern frame can be adjusted, thereby producing lanterns of different shapes and sizes to meet diverse usage needs. Figure 3 As shown, the connecting beam 3 and several connecting ribs 4 are curled into a circular shape to form a lantern skeleton structure. Figure 4 As shown, the snap ring groove 5 is annularly recessed and opened on the upper plate 1 and the lower plate 2. Align the two ends of the cylindrical keel frame with the snap ring groove 5 and push it in along the tangential direction until the connecting piece enters the avoidance groove 11.

[0041] A secondary bayonet 14 is provided on both the upper plate 1 and the lower plate 2, and the secondary bayonet 14 is communicated with the locking ring groove 5. A secondary opening 15 is provided on the upper plate 1 and the lower plate 2 in the secondary bayonet 14, and the secondary opening 15 is communicated with the secondary bayonet 14. A secondary clamping block 16 is provided on the two connecting beams 3 for clamping with the secondary opening 15 to clamp the connecting beam 3 in the locking ring groove 5 when the two connecting beams 3 are respectively clamped in the locking ring groove 5. The setting structure of the auxiliary buckle and the auxiliary opening 15 can be the same as that of the avoidance slot 11 and the locking opening 12. In this case, the auxiliary clamping block 16 has the same structure as the locking protrusion 13, and the setting position of the auxiliary clamping port 14 on the upper plate 1 and the lower plate 2 can be selected to correspond to the setting position of the avoidance slot 11 (the two positions are symmetrical to each other). In this case, the auxiliary clamping block 16 is set in the middle position of the connecting beam 3. This selection allows the user to freely choose one of the clamping ports (avoidance slot 11 or auxiliary clamping port 14) of the left connecting block 6 and the right connecting block 7 according to actual needs when inserting the connecting beam 3 into the locking ring groove 5. There is no need to find the corresponding locking position, and the auxiliary clamping block 16 can also be locked and connected with one of the openings (locking opening 12 or auxiliary opening 15), without worrying about the problem of mismatching the locking position. The setting shape of the auxiliary clamping 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 auxiliary bayonet 14, the auxiliary opening 15, the auxiliary clamping block 16 and the connecting beam 3 are integrally formed.

[0042] An escape opening 5 is provided at the connection between each of the connecting ribs 4 and the connecting beam 3 . The escape opening 5 is used to allow the connecting ribs 4 to avoid contact with the connecting beam 3 when the connecting ribs 4 are bent and deformed.

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

[0044] The limiting member includes a limiting groove 9 formed on the right connecting block 7 and a limiting protrusion 10 provided on the left connecting block 6 for passing through the connecting opening 8 of the right connecting block 7 and cooperating 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 opening 8, the limiting groove 9, the limiting protrusion 10, and the connecting crossbeam 3.

[0045] like Figure 9As shown, the connecting member includes a left connecting block 6 and a right connecting block 7, which are respectively arranged at the left and right ends of the two connecting beams 3, and a T-shaped card slot 29 provided on the right connecting block 7. The left connecting block 6 is a T-shaped card block 30, and the T-shaped card block 30 is loosely matched with the T-shaped card slot 29. The T-shaped card slot 29 can also be set as a card slot similar to the shape of a light bulb. In this case, the left connecting block 6 is set as a block with a shape similar to the light bulb shape and loosely matched with the card slot. The connecting member can also be selected as an adhesive fixing portion. When the left and right ends of the connecting beam 3 are in contact with each other, the left and right ends of the connecting beam 3 are adhesively fixed or hot-melt fixed. The connecting member can also be selected from other snap-fit ​​structures, as long as it can meet the requirements of fixing the left and right ends of the connecting beam 3.

[0046] The upper plate 1 and the lower plate 2 are both provided with an escape groove 11 for providing an escape space for the left connecting block 6 and the right connecting block 7 when the two connecting beams 3 are respectively clamped in the clamping ring groove 5. The escape groove 11 is connected to the clamping ring groove 5.

[0047] The upper plate 1 and the lower plate 2 are provided with a snap-fit ​​opening 12 in the avoidance groove 11, and the snap-fit ​​opening 12 is communicated with the avoidance groove. The left connecting block 6 is provided with a snap-fit ​​protrusion 13 for snapping with the snap-fit ​​opening 12 when the left connecting block 6 and the right connecting block 7 are avoided in the avoidance groove 11, so as to clamp the connecting beam 3 in the snap-fit ​​ring groove 5.

[0048] The design of the locking protrusions 13 ensures that the connecting crossbeam 3 is securely fixed within the locking ring groove 5 during assembly, preventing it from loosening. When the left and right connecting blocks 6 and 7 are positioned within the clearance grooves 11, the locking protrusions 13 automatically engage with the locking openings 12, forming a stable connection. This design not only improves the stability of the lantern frame but also simplifies the assembly process, making it more convenient and quicker to assemble.

[0049] The engaging protrusion 13 is a right-angled triangle. The upper plate 1 and the lower plate 2 are provided with chamfered surfaces at the ends avoiding the slot 11 to facilitate the engaging protrusion 13 to be engaged with the engaging opening 12 .

[0050] The right-angled triangular block's snap-fitting protrusion 13 creates a tighter locking effect when mated with the snap-fitting opening 12, further enhancing the stability of the connection. The chamfered surface cleverly eliminates the resistance of the snap-fitting protrusion 13 during insertion, making the assembly process smoother and easier to complete without requiring excessive manual effort.

[0051] Furthermore, the design of the avoidance slot 11 fully considers the maintenance requirements of the lantern frame during long-term use. Because the connecting crossbeam 3 is fixed by snapping rather than gluing, users can easily remove the connecting crossbeam 3 when cleaning, repairing, or replacing components, without worrying about component damage or difficulty in separation caused by gluing. This design not only improves the practicality of the lantern frame but also extends its service life, bringing greater convenience to users.

[0052] 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, and the guide hole 18 is clearance-matched with the guide rod 17 .

[0053] The lower end of the guide rod 17 is fixedly connected to the bottom center of the lower disk 2, and the guide hole 18 is opened at the top center of the upper disk 1 to ensure that the guide rod 17 can pass through the guide hole 18 smoothly. The outer surface of the guide rod 17 is smooth, and the inner wall of the guide hole 18 is also smooth accordingly to reduce the friction resistance between the two, so that the upper disk 1 can move smoothly during the lifting process. 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 shaking of the upper disk 1 during lifting. Such a design not only ensures the stability of the upper disk 1 during the lifting process, but also improves the reliability and durability of the entire lantern skeleton structure.

[0054] A positioning mechanism is provided between the guide rod 17 and the upper chuck for fixing the upper chuck on the guide rod 17 to keep the keel frame in the expanded state when the upper plate 1 approaches the lower plate 2 to expand the keel frame to form a lantern.

[0055] The positioning mechanism includes an inclined elastic piece 19 arranged in the middle of the guide rod 17, and a release deformation opening 20 opened in the middle of the guide rod 17 and located on one side of the inclined elastic portion for allowing the inclined elastic piece 19 to deform toward the guide rod 17 position.

[0056] like Figure 5 As shown, the inclined elastic piece is gradually tilted outward from top to bottom so as not to affect the descending effect of the upper plate 1 when the upper plate 1 descends. A locking notch 21 is provided on the inclined elastic piece 19.

[0057] There are two guide rods 17, and two guide holes 18 are formed on the upper plate 1. When one guide rod 17 is selected, the guide rod 17 is set in 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.

[0058] The upper ends of the two guide rods 17 are provided with fixing members for fixing the upper ends of the two guide rods 17 .

[0059] The fixing frame includes a fixing plate 22, and a fixing rod 23 is provided at the upper end of the two guide rods 17. The fixing plate 22 is provided with two fixing holes 24 for the fixing rod 23 to pass through. The diameter of the fixing hole 24 is smaller than the diameter of the fixing rod and larger than the diameter of the fixing rod 23. The upper end of the fixing rod 23 is provided with a snap-fit ​​head 25. The diameter of the snap-fit ​​head 25 is larger than the diameter of the fixing hole 24. The snap-fit ​​head 25 and the fixing rod 23 are provided with a deformation notch 26. The upper end of the snap-fit ​​head 25 is a circular arc surface. Figure 5 As shown, the engaging head 25 is an arc-shaped head, the length of the fixed through rod 23 is slightly greater than the height of the fixed plate 22, and 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 approach each other and produce deformation, making it easier for the engaging heads 25 to pass through the fixed through hole 24.

[0060] The fixing plate 22 is provided with a snap-fit ​​protrusion 27 located within the fixing hole 24. One or two snap-fit ​​protrusions 27 can be provided. When provided with two snap-fit ​​protrusions 27, they are symmetrically arranged, with a protrusion distance between them ranging from 0.1 to 0.7 mm. The snap-fit ​​protrusion 27 is integrally injection-molded with the fixing plate 22 and the fixing hole 24. It is positioned at the uppermost end of the fixing hole 24 and has a thickness ranging from 0.1 to 0.7 mm.

[0061] The lower plate 2 is provided with a guide hole 18, and the lower end of the guide rod 17 is provided with a limit 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, no matter whether the guide rod 17 is arranged in the middle or two symmetrically, the lower end of the guide rod 17 is fixed to the lower plate 2, and the fixation can be achieved by integral injection molding with the lower plate 2 or by welding or gluing after separate production. Figure 5 As shown, a snap-fit ​​rib is provided on the circumferential side of the lower end of the guide rod 17. The snap-fit ​​rib is used to cooperate with the guide rod 17 and the guide hole 18 of the lower disk member 2. After the lower end of the lower disk member 2 abuts against the limiting block 28, it is clamped in the guide hole 18 of the lower disk member 2 through the snap-fit ​​rib, so as to increase the stability of the guide rod 17 and the lower disk member 2 after installation.

[0062] The working principle of the present invention is as follows: when producing the keel frame, the connecting crossbeam 3 and a plurality of connecting ribs 4 are integrally formed, and then the connecting crossbeam 3 is curled so that its two ends are in contact, and the right connecting block 7 is pulled through the connecting opening 8, and the limiting protrusion 10 is matched with the limiting groove 9, thereby limiting the left and right movement of the right connecting block 7, so as to fix the two ends of the connecting crossbeam 3, prevent the curled connecting crossbeam 3 and the connecting rib 4 from being scattered due to the reaction force generated by the curling, so that the keel frame is formed into a cylindrical (or elliptical) shape, and then the two curled connecting crossbeams 3 are inserted into the locking ring groove. 5, the avoidance slot 11 is provided to provide an avoidance space for the left connecting block 6 and the right connecting block 7, so that when the connecting beam 3 is located in the snap ring groove 5, the setting of the left connecting block 6 and the right connecting block 7 will not affect the normal assembly. When the left connecting block 6 and the right connecting block 7 are inserted into the avoidance slot 11, the snap-fitting protrusion 13 is snapped into the snap-fitting opening 12 for snapping and matching, so as to clamp the connecting beam 3 in the snap ring groove 5. When the auxiliary snap-fitting block 16 is snapped into the auxiliary opening 15 for snapping and matching, the connecting beam 3 is clamped in the snap ring groove 5, and the curling can be made without bonding. The connecting crossbeam 3 is clamped with the upper plate 1 and the lower plate 2 to realize the connection and fixation of the connecting crossbeam 3 with the upper plate 1 and the lower plate 2. Then the guide rod 17 is passed through the guide hole 18 of the lower plate 2 from bottom to top, until the lower end of the lower plate 2 abuts against the limit block 28, and then the guide rod 17 is passed through the guide hole 18 of the upper plate 1, and the two fixed through-holes 24 are respectively aligned with the engaging heads 25 at the upper ends of the two guide rods 17, and the fixing sheet 22 is pressed down to squeeze the fixed through-holes 24 and the engaging heads 25, so that the engaging heads are engaged through the arc surface at the upper end of the engaging heads 25. The portion 25 is deformed and recessed by the arrangement of the deformation notch 26, thereby generating elastic potential energy, so that the engaging head 25 can pass through the fixed through-hole 24. After the engaging head 25 passes through the fixed through-hole, the engaging head 25 releases the elastic potential energy and resets. Since the diameter of the engaging head 25 is larger than the diameter of the fixed through-hole 24, and since the diameter of the fixed through-hole 24 is smaller than the diameter of the fixed rod and larger than the diameter of the fixed through-rod 23, the connecting end of the engaging head 25, the guide rod 17 and the fixed through-rod 23 fixes the position of the fixing piece 22, and the assembly process of the lantern frame can be completed. When the upper plate 1 approaches the lower plate 2 to expand the keel frame to form a lantern, the guide hole 18 of the upper plate 1 will contact the inclined elastic piece 19. As the upper plate 1 descends, the inclined elastic piece 19 will be pressed to deform in the direction of the release deformation opening 20 to generate elastic potential energy. When the inclined elastic piece 19 passes through the guide hole 18, the inclined elastic piece 19 releases the elastic potential energy and resets. The keel frame also generates elastic potential energy when it is expanded due to its elasticity and toughness, so it provides an upward reaction force to the upper plate 1. At this time, the upper plate 1 abuts against the lower end of the inclined elastic piece 19, thereby limiting the upward movement of the upper plate 1, so as to fix the upper chuck on the guide rod 17 to keep the keel frame in the expanded state; when it is necessary to release the upper chuck When the upper plate has a restrictive effect, the upper plate 1 is first pressed down to allow the inclined elastic piece 19 to move away from the upper plate 1 for a distance, and then the inclined elastic piece 19 is pressed to deform in the direction of the release deformation opening 20 until the inclined elastic piece 19 can pass through the position of the guide hole 18. At this time, the hand can slightly release the downward pressure on the upper plate 1, and use the elastic potential of the keel frame to lift the upper plate 1, so that the inclined elastic piece 19 can pass through the position of the guide hole 18, so that the keel frame can be folded into a cylinder, which can easily release the restrictive effect of the upper chuck and allow the keel frame to be folded into a cylinder for easy carrying and storage. This design of the assembled lantern frame structure not only improves the assembly efficiency and stability of the lantern, but also greatly enhances the user experience. By combining the connecting crossbeam 3 and the connecting rib 4, the production process of the traditional lantern keel frame is greatly simplified. Only the upper and lower plates 2 need to be simply assembled with the keel frame to quickly complete the construction of the entire lantern frame. Compared with the production of traditional keel frames, there is no need for tedious bending, correction and alignment installation steps, thereby significantly reducing labor costs and time costs.
