Description

Technical Field

[0001] This utility model relates to the field of outdoor equipment technology, specifically to a folding base frame and a folding grill. Background Technology

[0002] Outdoor grills are a common tool, typically featuring a structure with legs and a grill body. The legs rest on the ground while the grill body supports cookware and other items. They are used by placing combustibles, such as wood or charcoal, under the grill body, which, once ignited, heats the cookware and other items supported by the grill body. The drawback is that this type of outdoor grill cannot be resized, making it inconvenient to store, and therefore requires improvement. Summary of the Invention

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a folding base frame, including a base body one, a support rod one, and a support rod two. The base body one includes a plurality of radially arranged connecting rods. The outer ends of the connecting rods are hinged to support rod one and support rod two, and support rod one and support rod two rotate relative to the connecting rods they are on in the longitudinal plane. In use, support rod one, support rod two, and the ends of the connecting rods they are on form a trident shape.

[0005] When in use, rotate support rod one downwards relative to the connecting rod and support rod two upwards, so that support rod one connects to the ground to form support, and support rod two connects to the top frame, mesh body or furnace body and other mechanisms. When not in use, support rod one can be rotated upwards and support rod two can be rotated downwards. If support rod one, support rod two and the connecting rod are in a straight line, it will help to reduce the size of the base frame and facilitate storage.

[0006] In addition, the linkage can be either fixed or easily detachable, depending on the requirements. The easily detachable type helps to make storage even more convenient.

[0007] Common matrix configurations include trident, X-shaped, or more complex radial configurations.

[0008] Furthermore, the base body one includes connecting rod one and connecting rod two, which are connected in a cross manner, and the ends of connecting rod one and connecting rod two are hinged to each other.

[0009] Furthermore, slots are provided in the middle of both connecting rod one and connecting rod two. Connecting rod one and connecting rod two are inserted into each other with their slot openings facing each other to form a cross-connected configuration. In this solution, connecting rod one and connecting rod two form an easy-to-disassemble structure through slot connection, which helps to further improve the convenience of storage.

[0010] Furthermore, it also includes a locking plate and a fixing plate. A fixing plate is provided along the thickness direction at the slot of the upper slot of the first connecting rod, and a locking plate is hinged to the fixing plate. After the first connecting rod and the second connecting rod are inserted, the locking plate is rotated across the second connecting rod to limit the position. In this solution, the separation of the two connecting rods is restricted by the cooperation of the fixing plate and the locking plate, so as to further improve the support stability of the base frame.

[0011] Furthermore, a limiting block 1 and a limiting block 2 are provided at the end of the connecting rod. The limiting block 1 is located on the path of the first strut's upward rotation to limit its upward rotation range, and the limiting block 2 is located on the path of the second strut's upward rotation to limit its upward rotation range. In this solution, the addition of limiting blocks to limit the rotation range of the corresponding struts can improve the stability of the support.

[0012] Furthermore, protrusions are provided at the ends of the struts of strut one and strut two, and the limiting blocks one and two are located on the rotation path of the corresponding protrusions. It is not necessary to increase the width of the struts as a whole. By simply adding protrusions at the required positions to cooperate with the corresponding limiting blocks, the struts can be more easily restricted within the required rotation range.

[0013] The second aspect of this application discloses a grill, including a mesh body, a top frame, and the aforementioned bottom frame. The top frame is connected to a support rod one or a support rod two on the bottom frame at its side. The mesh body is located in the cavity formed by the top frame and the support rod connected to it. The mesh body is connected to the top frame or the support rod connected to the top frame.

[0014] When in use, if the second support rod is rotated to the top, it will connect with the top frame. Alternatively, the first support rod can be rotated to the top, and it will connect with the top frame. The net can be connected to the corresponding support rod or to the top frame. When in use, if combustible materials such as wood or charcoal are placed on the net and ignited, and pots or other utensils are placed on the top frame, the burning of the wood or other materials on the net will heat the pots or other utensils on the top frame.

[0015] For the connection between the netting and the top frame or support rods, multiple ropes can be installed on the side of the netting and tied to the top frame or corresponding support rods, or other hanging rods can be fixed to the netting. The connection between the netting and the top frame or corresponding support rods can be made through hanging rods or by connecting hanging rods with bolts, depending on the requirements.

[0016] Furthermore, the top frame includes a second base and frame rods connected to the sides of the second base. The other end of the frame rod away from the second base is hinged to a corresponding support rod, and the frame rod rotates relative to the support rod in the longitudinal plane. The configuration of the frame rod and the second base helps reduce weight. The hinged frame rod can rotate relative to the support rod, making it easy to store together with the corresponding connecting rod. For the second base, this configuration is not limited; it only needs to support the corresponding cookware, such as in a common flat shape, multiple concentric rings, or an X shape. The connection between the frame rod and the base can be achieved through methods such as interlocking, snap-fit ​​fixing, or bolt fixing.

[0017] Furthermore, the second base includes an X-shaped body with a stop block at the side end of the body. The end of the frame rod is connected to the side end of the body by fasteners and the frame rod is located below the stop block. The X-shaped body configuration helps to further reduce weight. Fasteners such as bolts can be used to connect the side end of the body to the end of the frame rod with a single bolt under the limitation of the stop block, which facilitates assembly.

[0018] Furthermore, connecting ropes are provided on the sides of the net body, and the connecting ropes are arranged in a loop around the net body. A rope groove is provided on the outside of the support rod connected to the top frame. Multiple rope grooves are matched to form a ring groove. The connecting rope that forms the ring is looped in the ring groove. In this example, the net body is connected to the corresponding support rod through the ring connecting rope. It can be fitted together during assembly, which is convenient for assembly and disassembly.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The base frame of this utility model can rotate relative to the corresponding connecting rods, which helps to reduce the size and facilitate storage.

[0021] 2. The design of the top frame and the mesh body facilitates assembly and storage. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1 , Figure 2 As shown, in this example, the grill includes a base frame 1, a top frame 3, and a wire mesh 2. The top frame 3 is installed on top of the base frame 1, and the wire mesh 2 is located in the cavity formed by the top frame 3 and the base frame 1, with the base frame 1 providing support for the wire mesh 2 and the top frame 3.

[0033] like Figure 1 , Figure 3 As shown, in this example, the base frame 1 includes a base body 1, a first strut 12, and a second strut 13. The base body 1 includes multiple connecting rods arranged radially, with the first strut 12 and the second strut 13 hinged to the outer ends of the connecting rods. In this example, the first strut 10 and the second strut 11 are arranged in an X-shape to form the base body 1, but a trident-shaped configuration can also be used.

[0034] Link 10 and Link 21 are the common long rod shapes, but they can also adopt configurations such as arc shapes. Link 10 and Link 21 are connected in a cross manner, such as... Figure 3 The overall structure is X-shaped. The ends of connecting rod 11 and connecting rod 212 are hinged to support rod 12 and support rod 213, respectively. Support rod 12 and support rod 213 rotate relative to their respective connecting rods in the longitudinal plane. For example... Figure 3 As shown, during use, strut 12 rotates downward relative to the connecting rod it is connected to, and strut 23 rotates upward relative to the connecting rod it is connected to. The ends of struts 12, 13, and their respective connecting rod ends form a three-pronged shape, and the four struts provide more stable support. For the hinge connections between struts 1 and 2 and their corresponding connecting rod ends, a common pivot hinge type can be chosen, depending on readily available technologies. Preferably, the ends of struts 1 and 2 are concentrically connected to their respective connecting rods, such as through the same pivot hinge; this configuration helps simplify the structure.

[0035] To limit the rotation range of strut 1 and strut 2, thereby improving the support stability of the base frame, limiting blocks 101 and 102 are added at the ends of connecting rod 11 and connecting rod 20, respectively. Figure 3As shown, both connecting rod 11 and connecting rod 10 have a predetermined position at their end sides that protrude outwards along the thickness direction. This protrusion corresponds to limiting block 101 or limiting block 102. Limiting block 101 is positioned on the path of the strut 12's upward rotation to limit its upward rotation amplitude. Figure 3 In the indicated state, the limiting block 101 ensures that the angle between the support rod 12 and the connecting rod is obtuse, such as 120°. The limiting block 102 is positioned on the path of the support rod 13's upward rotation to limit its upward rotation amplitude. Figure 3 In the state shown, the angle between the support rod 12 and the connecting rod is obtuse, such as 120°, due to the limiting block 101. That is, the ring formed by the support rod 1 is flared, and the ring formed by the support rod 2 is also flared, resulting in high support stability.

[0036] To better limit the range of rotation of the strut, such as Figure 3 , Figure 4 As shown, in this example, protrusions 121 are formed outward along the width direction at the end side of the strut body of strut 12 and strut 13. Limiting blocks 101 and 102 are located on the rotation path of the corresponding protrusions 121. If strut 12 rotates with protrusions 121 abutting against limiting blocks 101, the rotation is restricted. If strut 2 rotates with protrusions 121 abutting against limiting blocks 102, the rotation is also restricted. The purpose of limiting can be achieved by the local outward protrusion, which helps to reduce the weight of the strut.

[0037] For the cross connection of link one and link two, this example uses an easy-to-disassemble type, such as... Figure 4 , Figure 5 As shown, grooves, i.e. slots 103, are formed in the middle of both connecting rod 11 and connecting rod 2 10. During assembly, the slots 103 on connecting rod 11 and connecting rod 2 10 are aligned and inserted, and connecting rod 11 and connecting rod 2 10 form a cross-connected structure. When disassembling, they can be pulled outwards to detach.

[0038] To improve stability and prevent the disengagement of connecting rod 1 and connecting rod 2, a locking plate 15 and a fixing plate 16 can be optionally added. For example, a plate can be formed by protruding outward along the thickness direction at the end face of the slot on one side of connecting rod 1, i.e., fixing plate 16. The end of fixing plate 16 is hinged to a plate, i.e., locking plate 15, by bolts or shafts. Locking plate 15 can rotate horizontally. If connecting rod 11 is inserted with connecting rod 21 below and connecting rod 210 above, locking plate 15 is higher than connecting rod 210. Horizontally rotating locking plate 15 so that it spans connecting rod 210 restricts the upward movement of connecting rod 210 and locks the connection between connecting rod 1 and connecting rod 2. In addition, a fixing plate can also be formed at the slot on the other side of the slot on connecting rod 1. The end of the locking plate is bent upward to form an L-shape. The upward bending part can be forcefully applied to facilitate force application. After rotation, the upward bending part of the locking plate can have an interference fit with the side of the fixing plate at the slot on the other side, which helps to limit the locking plate and further improve stability.

[0039] As for the top rack, its configuration can be selected according to needs, as long as it provides support for cookware, etc. In this example... Figure 1 , Figure 2 The configuration shown is only a preferred structure. The top frame 3 includes a base 30 and a support rod 31 connected to the side of the base 30. In this example, the body of the base 30 is X-shaped, and the support rod 31 is hinged to the end of the side of the body. The support rod is arc-shaped or... Figure 1 The L-shaped support rod 31 shown in the image has its other end hinged to the corresponding strut 13, away from the base 2 30. Figure 1 In the state shown, the frame rod 31 rotates relative to the second support rod 13 in the longitudinal plane. The size can be further reduced by rotating the frame rod and the second support rod for easy storage. Of course, the body of the second base can also have other configurations, such as flat plate, groove, concentric ring, etc.

[0040] For the connection between the end of the support pole and the side end of the main body, methods include interlocking, snap-fit, or bolt fixing. For example... Figure 1 As shown, in this example, a single fastener is used in conjunction with a stop block to complete the connection. The fastener, such as a bolt, protrudes outward along the thickness direction at the side end of the body. The formed protruding part is the stop block 301. The end 311 of the support rod 31 is fixed to the side end of the body by the fastener, and the part of the support rod 31 behind the fastener is located below the stop block 301. The fastener and the stop block cooperate to limit the two points of the support rod, which helps to improve the structural strength and better support cookware and other mechanisms.

[0041] For the connection of the net body, multiple ropes can be installed on the side of the net body and tied to the frame poles or support poles. Alternatively, other poles can be installed on the side of the net body and fixed to the frame poles or support poles using bolts. For ease of assembly and disassembly, in this example, connecting ropes 4 are installed on the side of the net body 2. The connecting ropes 4 encircle the net body 2 in a loop, and grooves, i.e., rope grooves 14, are formed on the outer side of the support poles 13 connected to the frame pole 31. The rope grooves 14 on the four support poles 13 cooperate to form a ring groove. Figure 1 , Figure 2 As shown, the four connecting ropes forming a loop are fitted into the loop groove, and can be fitted together during assembly.

[0042] For the netting, if it is woven from refractory material, such as metal wire, when in use, the support rod is used to support the ground, and combustibles such as wood and charcoal are placed on the netting and ignited. Kettles, pots, etc. are placed on the base of the top frame. The combustibles on the netting burn to heat the pots on the top frame, and the burning residue can fall through the mesh.

[0043] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
