Technical Field

[0001] This utility model belongs to the field of outdoor camping products, specifically relating to a foldable portable fire pit. Background Technology

[0002] With the development of modern society, more and more people choose to experience the beauty of nature by outdoor camping. When camping outdoors, it is usually necessary to start a fire at the campsite for warmth or to cook food. The traditional method of starting a fire by gathering dry branches is prone to accidents, especially when the wind is strong. Therefore, more and more people are using fire pits to start a fire.

[0003] To better suit outdoor camping, various folding fire pits have been designed. However, existing folding fire pits suffer from unstable support, making them cumbersome to fold and unfold, requiring multiple structural components for assembly, and thus inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a foldable portable fire stand that is convenient to carry and use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a foldable portable fire stand, comprising several foldable frame components stacked sequentially from bottom to top, each foldable frame component having multiple insertion holes, and the insertion holes of each stacked foldable frame component being correspondingly arranged, with a connecting rod passing through each insertion hole to connect each foldable frame component in series.

[0006] Preferably, the folding frame assembly includes an even number and at least four connecting rods connected end to end, each connecting rod being rotatably connected to the others. Each connecting rod of the folding frame assembly is divided into two groups, and the two groups of connecting rods are arranged in upper and lower layers.

[0007] Preferably, the folding frame assembly includes six connecting rods connected end to end. When the folding frame assembly is unfolded, it is hexagonal. Each of the six connecting rods is divided into an upper connecting rod and a lower connecting rod, and the upper connecting rod and the lower connecting rod are arranged adjacent to each other.

[0008] Preferably, any two oppositely arranged connecting rods are broken at the middle and hinged at the break point, and the folding frame assembly is folded from the break point in the middle of the connecting rods.

[0009] Preferably, a positioning mechanism is provided between the two connected connecting rods. The positioning mechanism includes a folding latch, a positioning port, and a locking post. The folding latch and the positioning port are provided on the same connecting rod and are smoothly connected. The locking post is correspondingly and protrudingly provided on another connecting rod. When the folding frame assembly is opened, the locking post is locked in the positioning port. When the folding frame assembly is folded, the locking post is locked in the folding latch.

[0010] Preferably, a threaded connection part is provided at the bottom of the plug rod, and an internal thread is provided in the insertion hole on the bottommost folding frame assembly. The threaded connection part is threadedly connected to the insertion hole of the bottommost folding frame assembly. A fixing hole is provided at the top of the plug rod, and the lower part of the mounting cap is threadedly connected to the fixing hole. The diameter of the top of the mounting cap is larger than the diameter of the insertion hole.

[0011] Preferably, a number of air inlets are provided on the side of the bottommost folding frame assembly.

[0012] Preferably, when two adjacent layers of the folding frame components are stacked, they are rotated and staggered along the central axis.

[0013] Preferably, it also includes a support plate and a receiving box. The support plate is placed on the upper side of the bottommost folding frame assembly, and the receiving box is placed in the middle of the bottommost folding frame assembly. The receiving box is located below the support plate, and both the support plate and the receiving box are divided into two parts from the middle.

[0014] Preferably, any part of the receiving box is provided with an overlapping portion that bulges upward relative to another part of the receiving box, and the overlapping portion rests on the other part of the receiving box.

[0015] Preferably, it also includes a baking tray, the shape of which corresponds to the unfolded folding frame assembly, and the baking tray is placed on the uppermost folding frame assembly.

[0016] Compared with existing technologies, the above technical solution has the following beneficial effects: 1. This utility model includes several folding frame components stacked sequentially from bottom to top. The folding frame components are fixed by inserting rods passing through them sequentially. When not in use, each folding frame component is set separately. Each folding frame component can be folded to reduce the space occupied. When in use, it is only necessary to unfold the folding frame components and fix them sequentially by inserting rods. Installation and disassembly are very convenient and do not require complicated installation steps. In addition, the number of folding frame components can be selected according to the actual use. The number of folding frame components determines the final height of the fire platform, making it flexible in use.

[0017] 2. Each connecting rod of the folding frame assembly is divided into two groups, and the two groups of connecting rods are set in two layers. The two-layer connecting rods can be folded more compactly when folded, so that the folding frame assembly occupies less space after folding. The folding frame assembly includes six connecting rods connected end to end. When the folding frame assembly is unfolded, it is a regular hexagon. Any two of the connecting rods that are set opposite each other are disconnected in the middle and the disconnected part is rotated and connected. The folding frame assembly occupies only the distance of two groups of connecting rods side by side.

[0018] 3. Several air inlets are provided on the side of the bottom folding frame assembly to make the fuel in the combustion chamber burn more completely; the adjacent two layers of folding frame assemblies are rotated and staggered along the central axis, which not only makes the combustion chamber more beautiful, but also allows ventilation into the combustion chamber from the staggered position of the adjacent folding frame assemblies.

[0019] 4. The bottom thread of the plug rod is connected to the bottom folding frame assembly, making the plug rod more stable. A mounting cap is set on the top of the plug rod. The diameter of the top of the mounting cap is larger than the diameter of the plug hole. After the top folding frame assembly is placed, the mounting cap is screwed on the top of the plug rod. The mounting cap is pressed on the upper side of the top folding frame assembly, making the fire platform more stable.

[0020] 5. Both the support plate and the receiving box are divided into two parts from the middle, which takes up less space. At the same time, each part of the receiving box is convex upward and overlapped with the other part of the receiving box, which rests on the other part of the receiving box to prevent ash and slag from leaking from the middle of the receiving box.

[0035] Figures 1-13 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-13 The present invention will be further described below.

[0036] like Figures 1-2 As shown, this utility model discloses a foldable portable fire pit, which includes several foldable frame components 1 stacked sequentially from bottom to top. The foldable frame components 1 can be opened or folded. When the fire pit is in use, the opened foldable frame components 1 are stacked. Each foldable frame component 1 has multiple insertion holes 5, and the insertion holes 5 of each stacked foldable frame component 1 are correspondingly arranged. The insertion rod 2 passes through each insertion hole 5 in sequence to connect each foldable frame component 1. After the insertion rod 2 is inserted into each foldable frame component 1, the foldable frame components 1 can be fixedly connected to complete the installation of the fire pit.

[0037] The folding frame assembly 1 includes an even number, and at least four, connecting rods 3 connected end-to-end. For example, it can be a rectangular frame composed of four connecting rods 3, where each connecting rod 3 can rotate to fold the folding frame assembly 1, reducing the space occupied by the incinerator after folding; or a hexagonal frame composed of six connecting rods 3, where each connecting rod 3 is also rotatably connected; or an octagonal frame composed of eight connecting rods 3. When folding the folding frame assembly 1, pushing the connecting rod 3 inward along any diagonal will fold the unfolded folding frame assembly 1. In this embodiment, all connecting rods 3 are of the same model and specification. Therefore, each connecting rod 3 of the folding frame assembly 1 is divided into two groups, with the two groups of connecting rods 3 arranged in upper and lower layers. After folding the folding frame assembly 1, the connecting rods 3 can be folded into two layers, making folding and carrying more convenient.

[0038] like Figure 3As shown, the folding frame assembly 1 in this embodiment includes six connecting rods 3 connected end to end. When the folding frame assembly 1 is unfolded, it is a regular hexagon. Adjacent connecting rods 3 are rotatably connected by pins. The six connecting rods 3 are divided into upper connecting rods 301 and lower connecting rods 302, and the upper connecting rods 301 and lower connecting rods 302 are arranged adjacent to each other. After the connecting rods 3 are set as two layers, when the folding frame assembly 1 is unfolded, the folding frame assembly 1 is the height of two layers of connecting rods 3. After stacking the folding frame assembly 1, there is a gap between each pair of adjacent folding frame assembly 1. The gaps allow ventilation to enter the fire pit, which is conducive to better fire starting. Insertion holes are opened on at least three connecting rods 3 to ensure that the stacked folding frame assembly 1 can remain stable.

[0039] In this embodiment, any two oppositely arranged connecting rods 3 are disconnected at the middle and hinged at the disconnection point. The disconnected connecting rod 3 serves as a folding rod 4. The folding frame assembly 1 is folded from the middle of the folding rod 4. By disconnecting two oppositely arranged connecting rods 3 to serve as folding rods 4, the hexagonal folding frame assembly 1 can be completely folded into two sets side by side. Moreover, the folded folding frame assembly 1 is not very long, reducing the space occupied after folding and making it more convenient to carry.

[0040] like Figures 4-8 As shown, a latch 6 and a positioning port 18 are provided on the upper connecting rod 301. The folding latch 6 and the positioning port 18 are smoothly connected. A latch 7 is provided at the corresponding position of the two adjacent lower connecting rods 302. After the folding frame assembly 1 is opened, the latch 7 is locked in the positioning port 18 to prevent the folding frame assembly 1 from becoming unstable after being opened. After the folding frame assembly 1 is folded, the latch 7 is locked in the folding latch 6 to ensure that the folding frame assembly 1 will not be easily folded during installation or use.

[0041] In this embodiment, the two adjacent folding frame assemblies 1 are rotated and staggered along the central axis, which not only makes the fire platform more aesthetically pleasing, but also allows ventilation into the fire platform from the staggered position of the adjacent folding frame assemblies 1. In this embodiment, the insertion holes 5 are all opened on the three connecting rods 3 on the upper layer. Since the adjacent folding frame assemblies 1 need to be staggered, two insertion holes 5 need to be symmetrically set on one connecting rod 3 to ensure that the adjacent folding frame assemblies 1 still have corresponding insertion holes 5 after rotating a certain angle.

[0042] like Figure 9As shown, a threaded connection part 8 is provided at the bottom of the plug-in rod 2, and an internal thread is provided in the insertion hole 5 on the bottommost folding frame assembly 1. The threaded connection part 8 is threaded into the insertion hole 5 of the bottommost folding frame assembly 1, making the plug-in rod 2 more stable. Then, the folding frame assemblies 1 are stacked layer by layer from the top of the plug-in rod 2. A fixing hole 10 is opened at the top of the plug-in rod 2. An installation cap 9 is installed in the fixing hole 10. The lower part of the installation cap 9 is threaded into the fixing hole 10. The diameter of the top of the installation cap 9 is larger than the diameter of the insertion hole 5. After the topmost folding frame assembly 1 is placed, the installation cap 9 is screwed onto the top of the plug-in rod 2. The installation cap 9 presses on the upper side of the topmost folding frame assembly 1, making the fire platform more stable.

[0043] like Figures 10-12 As shown, this utility model also includes a support plate 11 and a receiving box 12. The support plate 11 is placed on the upper side of the bottom folding frame assembly 1. In this embodiment, the support plate 11 is placed on the lower connecting rod 302 of the bottom folding frame assembly 1. The receiving box 12 is placed in the middle of the bottom folding frame assembly 1. The receiving box 12 is placed on a horizontal ground like the bottom folding frame assembly 1. The support plate 11 is used to place the combustion material, and the receiving box 12 is located below the support plate 11. The receiving box 12 catches the falling ash. In order to make the support plate 11 and the receiving box 12 more convenient to carry and reduce the space occupied by the support plate 11 and the receiving box 12, the support plate 11 and the receiving box 12 are divided into two parts from the middle. When in use, the two parts can be aligned and placed. Since the receiving box 12 needs to collect ash and slag, in order to prevent ash and slag from leaking out from the split position in the middle of the receiving box, an overlapping part 14 is provided at the point where one part of the receiving box 12 is convex upward relative to the other part of the receiving box 12. When in use, the overlapping part 14 is placed on the other part of the receiving box 12 to prevent ash and slag from leaking out.

[0044] In this embodiment, several air inlets 17 are provided on the side of the bottommost folding frame assembly 1. The air inlets 17 allow natural wind to enter the combustion platform from below the support plate 11, which makes it easier for the combustion material on the support plate 11 to burn. Therefore, the bottommost folding frame assembly 1 is different from the other folding frame assemblies 1. The bottommost folding frame assembly 1 needs to be provided with air inlets 17, and internal threads need to be provided in the insertion holes 5 of the bottommost folding frame assembly 1. The other folding frame assemblies 1 are exactly the same and can be stacked without distinction, making them more convenient to use.

[0045] like Figure 13As shown, this utility model also includes a baking tray 13, which is also hexagonal in shape. The baking tray 13 is also split from the center for easy carrying. The edge of the baking tray 13 is bent downward to form a vertical folding fixing part 15. The vertical folding fixing part 15 is locked on the outside of the top folding frame assembly 1 to prevent the baking tray 13 from moving at will. At the same time, since the mounting cap 9 is pressed on the top folding frame assembly 1, the baking tray 13 is also provided with a corresponding clearance hole 16 for the mounting cap 9.

[0046] In use, the bottommost folding frame assembly 1 is opened outwards from the middle of the folding rod 4. The lower ends of at least three connecting rods 2 are screwed onto the insertion holes 5 of the bottommost folding frame assembly 1. The support plate 11 is placed on top of the bottommost folding frame assembly 1. The remaining folding frame assemblies 1 are then opened sequentially and installed from the top of the connecting rods 2. The mounting cap 9 is installed on the top of the connecting rods 2 to press down the topmost folding frame assembly 1. The receiving box 12 and the fire pit are then placed, and the fire can be started. When not in use, each folding frame assembly 1 is separate, and all folding frame assemblies 1 can be folded to reduce the space occupied. In use, only the folding frame assemblies 1 need to be opened, the connecting rods 2 installed on the bottommost folding frame assembly 1, and then the remaining folding frame assemblies 1 installed sequentially. Installation and disassembly are very convenient, requiring no complicated installation steps. Furthermore, the number of folding frame assemblies 1 can be selected according to actual usage, and the number of folding frame assemblies 1 determines the final height of the fire pit, making it flexible in use.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
