Description

Technical Field

[0001] This utility model relates to a furnace frame, specifically an extended furnace frame. Background Technology

[0002] In outdoor camping and barbecue scenarios, the grill rack needs to support heat sources such as okatas and portable gas stoves, as well as accessories like barbecue trays and food baskets. Traditional grill racks typically consist of a top frame and several supporting legs, and their inherent structure suffers from the following technical drawbacks:

[0003] 1. Area limitations: The fixed size of the top frame severely restricts the possibility of placing multiple utensils at the same time, which is especially prominent when operating large baking pans or placing spare ingredients.

[0004] II. Expansion Limitations: Existing expansion solutions mainly use independent external components, which have three major drawbacks:

[0005] ① Storage issues: Storing external components separately from the main unit not only increases storage volume but also makes it easier for accessories to be lost;

[0006] ② Ease of use: It requires repeated manual disassembly and assembly, and is difficult to operate in oily environments;

[0007] ③ Economic disadvantages: Additional components significantly increase production costs and reduce the product's market competitiveness. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an expandable stove rack that is simple to use, easy to store, and highly competitive in the market.

[0009] The technical problem of this utility model is solved by the following technical solution:

[0010] An extendable furnace frame includes a top frame and several support rods for the top frame. An extendable frame is provided at the end of the top frame. The extendable frame includes a pull rod and connecting rods fixed to both ends of the pull rod. The connecting rods are slidably inserted into the end of the top frame, allowing the extendable frame to switch between an extended position and a retracted position. In the extended position, the connecting rods extend outward from the end of the top frame, forming an extended platform. In the retracted position, the connecting rods retract into the end of the top frame, and the pull rods fit against the outer side of the end of the top frame.

[0011] The top frame is provided with a sliding channel at its end, and the connecting rod slides with the top frame through the sliding channel.

[0012] The top frame includes two parallel top rods and a side rod connecting the two top rods. The top rods are hollow tubular structures with sliding channels inside for the connecting rods to slide.

[0013] A limiting mechanism for positioning is provided between the connecting rod and the top rod, and the limiting mechanism locks the unfolded position and the retracted position of the extension frame.

[0014] The limiting mechanism includes an elastic positioning member disposed on the connecting rod, and at least two limiting holes disposed on the top rod and spaced apart along the axial direction of the top rod. The elastic positioning member can be elastically engaged into the limiting holes at different positions to achieve the locking of the extension frame.

[0015] The outer side wall of the top rod is provided with an extension plate, and the inner side wall of the top rod is provided with several mounting posts.

[0016] The outer side wall of the top rod is provided with a slider extending along the axial direction of the top rod. The outer side surface of the slider is provided with a mounting groove extending along the axial direction of the slider. Correspondingly, the outer edge of the expansion plate is provided with a sliding rib that matches the mounting groove, and the sliding rib is detachably slidably disposed in the mounting groove.

[0017] The extension plate and the slider are provided with interlocking claws and grooves.

[0018] Each of the aforementioned foot posts is provided with a diagonal brace between itself and the top frame.

[0019] Each of the aforementioned legs includes an inner rod and an outer rod that are telescopically connected to each other. The top end of the outer rod is connected to the top frame, and the bottom end of the outer rod is provided with a positioning pin hole for locking the telescopic height of the inner rod.

[0020] Compared with existing technologies, the main feature of this invention is the addition of an extension frame at the end of the top frame. This extension frame includes a pull rod and connecting rods fixedly connected to both ends of the pull rod, with the connecting rods slidably inserted into the end of the top frame. This allows the extension frame to switch between an extended and retracted position. In the extended position, simply extend the connecting rods outward from the end of the top frame to form an extended platform, increasing the usable area of ​​the top surface. In the retracted position, simply retract the connecting rods into the end of the top frame and place the pull rods against the outer side of the end of the top frame, completely concealing the extension frame. Therefore, the improved structure offers advantages such as ease of use and convenient storage. In particular, by directly placing the extension frame at the end of the top frame, and with its structure consisting only of simple pull rods and connecting rods, it is less prone to loss, expands the usable area, and does not increase production costs excessively, thus enhancing the product's market competitiveness.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

The same labels in each figure represent the same parts.

[0032] An extendable grill rack, primarily used in outdoor camping and barbecue settings, is designed to support heat source equipment such as okata grills and portable gas stoves, as well as barbecue trays, food baskets, and other accessories. Its structure includes a top frame 1 and several support legs 2. For example, this embodiment... Figure 1 The top frame 1 is a rectangular frame structure consisting of two parallel top rods 11 and two parallel side rods 12, with the two side rods connecting to the two top rods. The top rods 11 serve as the long side and the side rods 12 serve as the short side. Several mounting columns 112 are provided on the inner sidewalls of the two top rods 11 to facilitate the stable placement of heat source equipment such as Iwatani furnaces and cassette furnaces inside the top frame 1.

[0033] The outer side wall of the top rod 11 may be provided with an extension plate 4 to increase the usable area of ​​the top frame 1 on the long side. In this embodiment, two extension plates 4 are provided on the outer side wall of each top rod 11. The two extension plates can be spliced ​​together along the length direction to avoid the entire extension plate being too long and increasing the supporting weight. Therefore, the number of extension plates 4 is mainly selected according to the specific length of the top rod 11.

[0034] Meanwhile, the mounting structure of each expansion plate 4 is exactly the same, as follows: Figures 3-5 As shown, a slider 113 extending axially along the top rod 11 is provided on the outer wall of the top rod 11. The slider is a strip-shaped rectangular block, and its axial length is usually the same as the length of the top rod 11. The top surface of the slider 113 should not be higher than the top surface of the top rod 11. A mounting groove 114 extending axially along the outer surface of the slider 113 is provided, with both ends of the mounting groove passing through both ends of the slider 113. Then, a sliding rib 41 matching the mounting groove 114 is provided on the outer edge of the extension plate 4. This embodiment, for example... Figure 4 The slide rib 41 with a mushroom-shaped cross-section and a matching mounting groove 114 are shown. The slide rib 41 can be detachably slid into the mounting groove 114 from the end of the slider 113, which facilitates the quick assembly and disassembly of the extension plate 4 on the outer side wall of the top rod 11.

[0035] The expansion plate 4 and the slider 113 are also provided with interlocking claws 42 and locking grooves 115. Specifically, the claws 42 are also set on the outer edge of the expansion plate 4 and above the sliding rib 41, while the locking groove 115 is set on the top surface of the slider 113. After the expansion plate 4 is installed on the outer side wall of the top rod 11 through the sliding rib 41 and the mounting groove 114, it is also connected to the locking groove 115 through the claws 42. This increases the connection strength between the expansion plate 4 and the top rod 11 and prevents the expansion plate 4 from bending and sagging relative to the top rod 11 after installation, which would affect normal use.

[0036] The top frame 1 is provided with an extension frame 3 at one end, specifically as follows: Figure 1 , Figure 2 As shown, the extension frame 3 is set on the outside of the two side rods 12 respectively. The structure of the extension frame 3 on the outside of each side rod is exactly the same, and the extension frame 3 expands the load-bearing area of ​​the top frame 1, that is, increases the usable area of ​​the top frame on the short side.

[0037] The extension frame 3 includes a pull rod 31 and connecting rods 32 vertically fixed at both ends of the pull rod, thereby forming a U-shaped structure.

[0038] The top frame 1 has a sliding channel at its end, through which the connecting rod can be slidably inserted into the end of the top frame 1, allowing the extension frame 3 to switch between an extended position and a retracted position. Specifically, the top rod 11 is a hollow tubular structure, and its interior forms a sliding channel for the connecting rod 32 to slide. Figure 2 When in the extended position shown, the connecting rods 32 can extend outward from the end of the top frame 1, that is, the two connecting rods 32 of the extension frame 3 extend outward from the sliding channels of the two top rods 11, thus forming an extension platform with the extension frame 3; Figure 8 When in the retracted position shown, the connecting rod 32 retracts into the end of the top frame 1, that is, the two connecting rods 32 of the extension frame 3 retract into the sliding channels of the two top rods 11 respectively, and drive the pull rod 31 to fit against the outer side of the end of the top frame 1. At this time, the extension frame 3 can be completely hidden.

[0039] A limiting mechanism for positioning is also provided between the connecting rod 32 and the top rod 11, which locks the unfolded and retracted positions of the extension frame. The limiting mechanism includes an elastic positioning element (not shown in the figure) provided on the connecting rod 32, and at least two limiting holes 111 correspondingly provided on the top rod 11 and spaced apart along the axial direction of the top rod. The elastic positioning element can be a V-shaped spring buckle or an elastic protrusion pushed by a spring, etc. Since the elastic positioning element has been widely used in existing telescopic locking rods, its specific structure will not be described in detail in this application.

[0040] When the elastic positioning member is elastically engaged in the limiting hole 111 at different positions, the position locking of the extension frame 3 can be achieved. For example, when the elastic positioning member is fitted into the limiting hole 111, it can restrict the sliding of the connecting rod 32. When the elastic positioning member is disengaged from the limiting hole 111, the sliding of the connecting rod 32 can be achieved.

[0041] This implementation example Figure 2 As shown, each end of the extension frame 3 is equipped with two limiting holes 111. These two limiting holes 111 correspond to the locking of the extension frame 3 in the unfolded and retracted positions. It is also preferable to design a pull-out anti-detachment structure on the connecting rod 32 to prevent the extension frame 3 from detaching from the end of the top frame 1 due to the extreme outward pull of the connecting rod 32. Since this anti-detachment structure is widely used in existing telescopic locking rods, it will not be described in detail in this application.

[0042] There are four leg rods 2, which are respectively set at the four corners of the rectangle of the top frame 1. Each leg rod 2 includes an inner rod 22 and an outer rod 21 that are telescopically connected to each other. The top end of the outer rod is connected to the top frame 1, and the bottom end of the outer rod is provided with a positioning pin hole 23 for locking the telescopic height of the inner rod. For example, a set screw can be inserted into the positioning pin hole, and the telescopic height between the inner rod 22 and the outer rod 21 can be locked or adjusted by tightening or loosening the set screw in the positioning pin hole 23. In addition, each leg rod 2 is provided with a diagonal brace 5 between itself and the top frame 1 to strengthen the structural support.

[0043] In addition, to facilitate the storage of the furnace frame, this embodiment also designs the leg rod 2 to be foldable relative to the top frame 1. Typically, the top of the outer rod is hinged to the top frame, and the diagonal support rod 5 is designed to be foldable and locked. When the leg rod 2 is unfolded, it drives the diagonal support rod 5 to unfold and lock simultaneously, so the furnace frame is in the unfolded use state. When the diagonal support rod 5 is unlocked and folded, the corresponding leg rod 2 can also be folded onto the top frame 1, so the furnace frame is in the folded storage state.

[0044] This utility model has the advantages of being simple to use and easy to store. In particular, the extension frame 3 is directly configured at the end of the top frame 1, and its structure consists of only a simple pull rod 31 and a connecting rod 32. It is not easy to lose and can expand the usable area, but it will not increase the production cost too much, thereby improving the market competitiveness of the product.

[0045] The basic principles and main features of this utility model have been described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as claimed. The scope of protection of this utility model is defined by the appended claims and their equivalents.
