Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a stove ear assembly, stove rack and stove. Background Technology

[0002] The cooktop frame is a support structure in a household gas stove used to support cookware. It typically includes a ring-shaped mounting ring and multiple support ears spaced circumferentially along the mounting ring, on which the cookware is supported.

[0003] Existing cookware typically comes in two types: flat-bottomed pans and curved-bottomed pans. To support different types of cookware, existing technology provides a stove rack with a stove ear that includes a fixed part and a rotating part mounted on the fixed part. By adjusting the position of the rotating part, support can be provided for both flat-bottomed and curved-bottomed pans.

[0004] In existing technology, the rotating part is rotatably mounted on the fixed part via a threaded pin, and the threaded section of the pin is screwed with a nut to prevent the rotating part from detaching. However, this assembly method requires tools to rotate the nut and pin during disassembly and assembly, making the disassembly and assembly of the furnace frame relatively troublesome and not conducive to improving the efficiency of furnace frame disassembly and assembly; at the same time, when assembling and disassembling the rotating part relative to the fixed part, the pin is easy to be lost, which affects the assembly of the furnace frame. Utility Model Content

[0005] One of the technical problems to be solved by this utility model is to provide a furnace ear assembly that can effectively solve the problem of troublesome disassembly and assembly of existing furnace ears and improve the efficiency of furnace ear disassembly and assembly.

[0006] The second technical problem solved by this utility model is to provide a furnace frame that can effectively solve the problem of troublesome disassembly and assembly of existing furnace frames and improve the efficiency of furnace frame disassembly and assembly.

[0007] The third technical problem solved by this utility model is to provide a stove that can effectively solve the problem of troublesome stove disassembly and assembly caused by the troublesome disassembly and assembly of the stove frame, and improve the disassembly and assembly efficiency of the stove frame and the stove.

[0008] The first technical problem mentioned above is solved by the following technical solution:

[0009] A furnace ear assembly includes a fixed furnace ear, a movable furnace ear, a connecting shaft, and a first elastic ring, wherein the movable furnace ear is rotatably mounted to the fixed furnace ear via the connecting shaft;

[0010] The fixed furnace ear is provided with a fixed shaft hole, the movable furnace ear is provided with a rotating shaft hole coaxial with the fixed shaft hole, the hole wall of the fixed shaft hole and / or the rotating shaft hole is provided with a first annular groove, the connecting shaft is provided with a second annular groove, and the first annular groove, the second annular groove and the first elastic ring are provided in a one-to-one correspondence;

[0011] The first elastic ring is sleeved in the second annular groove of the connecting shaft. When the connecting shaft is assembled or removed, the first elastic ring can move synchronously with the connecting shaft to enter or leave the first annular groove; or, the first elastic ring is disposed in the first annular groove. When the connecting shaft is assembled or removed, the first elastic ring can be expanded by the connecting shaft and reset to enter the second annular groove or expanded by the connecting shaft to leave the second annular groove.

[0012] The furnace ear assembly of this utility model has the following advantages compared with the prior art: By setting a first elastic ring, a first annular groove, and a second annular groove, when assembling the furnace ear assembly, the first elastic ring is first placed in the second annular groove (or the first annular groove). When the connecting shaft passes through the fixed shaft hole and the rotating shaft hole, the first elastic ring is squeezed into the second annular groove (or the first annular groove) by the hole wall (or by the connecting shaft), thereby preventing the first elastic ring from obstructing the connecting shaft from passing through the fixed furnace ear and the movable furnace ear; when the connecting shaft moves to the first annular groove and the second annular groove... When the groove is aligned axially with the connecting shaft, the first elastic ring recovers under its own elastic restoring force, allowing the outer ring wall of the first elastic ring to engage with the first annular groove and the inner ring wall to engage with the second annular groove, thus achieving axial positioning. When it is necessary to pull out or continue pulling the connecting shaft, pulling the connecting shaft forcefully will cause the first elastic ring to be squeezed and deformed again, falling into the second annular groove (or the first annular groove), enabling further movement of the connecting shaft relative to the fixed and movable furnace ears, thereby achieving the installation of the connecting shaft or the disassembly of the mounting shaft. That is, the furnace ear assembly provided by this utility model, by setting the first elastic ring, the first annular groove and the second annular groove, allows the connecting shaft to be inserted and withdrawn in the fixed shaft hole and the rotating shaft hole by pulling the connecting shaft, without the need for other tools, making disassembly and assembly highly convenient and improving disassembly and assembly efficiency; at the same time, when reassembling or disassembling, since the first elastic ring can always be placed in the first annular groove or the second annular groove, it is possible to prevent the loss of furnace ear assembly parts during the assembly and disassembly process, ensuring smooth assembly and disassembly.

[0013] In one embodiment, the movable furnace ear includes two ear plate portions arranged opposite to each other and spaced apart, and a support plate portion connected between the two ear plate portions. Both ear plate portions are provided with the rotating shaft hole. The fixed furnace ear is located between the two ear plate portions. The two ends of the connecting shaft pass through the two rotating shaft holes. The support plate portion is located above the fixed furnace ear.

[0014] In one embodiment, the first annular groove is formed on the wall of the fixed shaft hole and the wall of at least one of the rotating shaft holes.

[0015] In one embodiment, the wall of the fixed shaft hole is provided with the first annular groove, and two mounting annular grooves are provided on the connecting shaft, the mounting annular grooves being located on opposite sides of the first annular groove;

[0016] The furnace ear assembly also includes a second elastic ring, which is configured to correspond one-to-one with the mounting ring groove. The second elastic ring is sleeved on the connecting shaft and can be positioned in the mounting ring groove with its inner ring wall and its outer ring wall protruding from the connecting shaft when it is not squeezed. The second elastic ring can be accommodated in the mounting ring groove under the squeezing action of the ear plate.

[0017] The two ends of the connecting shaft are inserted into two rotating shaft holes, and the two second elastic rings are respectively located between the ear plate and the fixed furnace ear and restrict the ear plate from moving toward the fixed furnace ear.

[0018] In one embodiment, the second elastic ring is an open annular structure, and the central angle corresponding to the second elastic ring is greater than 180°.

[0019] In one embodiment, when the first elastic ring is not compressed and deformed, the inner diameter of the first elastic ring is D1, the outer diameter of the first elastic ring is D2, the diameter corresponding to the bottom of the first annular groove is D3, the diameter corresponding to the bottom of the second annular groove is D4, the shaft diameter of the connecting shaft is D5, and the diameters of the fixed shaft hole and the rotating shaft hole are D6.

[0020] D1≤D4<D5<D6<D2<D3, or, D4<D1<D5<D6<D3≤D2.

[0021] In one embodiment, D1 ≤ D4, and (D3-D2) > (D5-D1);

[0022] Alternatively, D3≤D2, and (D1-D4)>(D2-D6).

[0023] In one embodiment, the first elastic ring is an open annular structure, and the central angle corresponding to the first elastic ring is greater than 180°.

[0024] And / or, at least one end of the connecting shaft is provided with a chamfer.

[0025] The second technical problem mentioned above is solved by the following technical solution:

[0026] A furnace frame includes an annular base and furnace ear assemblies as described above, wherein multiple furnace ear assemblies are arranged at circumferential intervals along the annular base.

[0027] Compared with the prior art, the stove frame described in this utility model has the following advantages: by adopting the above-mentioned stove ear assembly, the stove frame can support flat-bottomed pots and curved-bottomed pots while improving the disassembly and assembly performance of the stove frame.

[0028] The third technical problem mentioned above is solved by the following technical solution:

[0029] A stove, including the rack as described above.

[0030] Compared with the prior art, the stove described in this utility model has the following advantages: by adopting the above-mentioned stove rack, the stove can support both flat-bottomed and curved-bottomed pans while improving the assembly and disassembly performance of the stove.

[0055] Example 1

[0056] This utility model embodiment provides a stove rack that is compatible with both flat-bottomed pans and curved-bottomed pans 300, while improving the assembly and disassembly performance of the stove rack and enhancing its stability and reliability.

[0057] like Figures 1 to 4 As shown, the stove frame includes an annular base 200 and stove ear assemblies 100, with multiple stove ear assemblies 100 spaced apart circumferentially along the annular base 200. Each stove ear assembly 100 includes a fixed stove ear 1, a movable stove ear 2, and a connecting shaft 3. The movable stove ear 2 is rotatably mounted to the fixed stove ear 1 via the connecting shaft 3, allowing the movable stove ear 2 to rotate between a first position and a second position. Thus, when the movable stove ear 2 is in the first position, the stove frame can support a flat-bottomed pan, while when the movable stove ear 2 is in the second position, the stove frame can support a curved-bottomed pan 300.

[0058] like Figures 5 to 9 As shown, in this embodiment, the furnace ear assembly 100 further includes a first elastic ring 5. A fixed shaft hole 14 is provided on the fixed furnace ear 1, and a rotating shaft hole 211 coaxial with the fixed shaft hole 14 is provided on the movable furnace ear 2. A first annular groove 4 is provided on the hole wall of the fixed shaft hole 14 and / or the rotating shaft hole 211, and a second annular groove 31 is provided on the outer side wall of the connecting shaft 3. The first annular groove 4, the second annular groove 31, and the first elastic ring 5 are provided in a one-to-one correspondence. The first elastic ring 5 is sleeved in the second annular groove 31 of the connecting shaft 3. When assembling or removing the connecting shaft 3, the first elastic ring 5 can move synchronously with the connecting shaft 3 to enter or leave the first annular groove 4; or, the first elastic ring 5 is provided in the first annular groove 4. When assembling or removing the connecting shaft 3, the first elastic ring 5 can be expanded by the connecting shaft 3 and reset to enter the second annular groove 31 or expanded by the connecting shaft 3 to leave the second annular groove 31.

[0059] The furnace ear assembly 100 provided in this embodiment, by setting a first elastic ring 5, a first annular groove 4, and a second annular groove 31, ensures that during the assembly of the furnace ear assembly 100, the first elastic ring 5 is first placed in the second annular groove 31 (or the first annular groove 4). When the connecting shaft 3 passes through the fixed shaft hole 14 and the rotating shaft hole 211, the first elastic ring 5 is squeezed into the second annular groove 31 (or the first annular groove 4) by the hole wall (or by the connecting shaft 3), thereby preventing the first elastic ring 5 from obstructing the connecting shaft 3 from passing through the fixed furnace ear 1 and the movable furnace ear 2; when the connecting shaft 3 moves to the first annular groove 4 and the second annular groove 31, the first elastic ring 5 is placed in the second annular groove 31 (or the first annular groove 4). When the connecting shaft 3 is aligned axially, the first elastic ring 5 recovers under its own elastic restoring force, so that the outer ring wall of the first elastic ring 5 can be inserted into the first ring groove 4 and the inner ring wall can be inserted into the second ring groove 31, thus achieving axial positioning. When it is necessary to pull out or continue to pull the connecting shaft 3, by pulling the connecting shaft 3 with force, the first elastic ring 5 can be squeezed and deformed again and fall into the second ring groove 31 (or the first ring groove 4), so that the connecting shaft 3 can move further relative to the fixed furnace ear 1 and the movable furnace ear 2, thereby realizing the installation of the connecting shaft 3 or the disassembly of the mounting shaft.

[0060] That is, the furnace ear assembly 100 provided in this embodiment, by setting the first elastic ring 5, the first annular groove 4 and the second annular groove 31, can realize the insertion and withdrawal of the connecting shaft 3 in the fixed shaft hole 14 and the rotating shaft hole 211 by pulling the connecting shaft 3, without the need for other tools, which makes disassembly and assembly highly convenient and improves disassembly and assembly efficiency; at the same time, when reassembling and disassembling, since the first elastic ring 5 can always be placed in the first annular groove 3 or the second annular groove 31, the loss of the parts of the furnace ear assembly 100 during the assembly and disassembly process is avoided, ensuring the smooth progress of assembly and disassembly.

[0061] In one embodiment, when the movable stove lug 2 is in the first position, the movable stove lug 2 can support the flat-bottomed pan; when the movable stove lug 2 is in the second position, the movable stove lug 2 can support the curved-bottomed pan 300. In other embodiments, when the movable stove lug 2 is in the first position, the fixed stove lug 1 supports the flat-bottomed pan, and when the movable stove lug 2 is in the second position, the movable stove lug 2 can support the curved-bottomed pan 300.

[0062] Definition: When the first elastic ring 5 is not compressed, the inner diameter of the first elastic ring 5 is D1, the outer diameter of the first elastic ring 5 is D2, the diameter corresponding to the bottom of the first annular groove 4 is D3, the diameter corresponding to the bottom of the second annular groove 31 is D4, the shaft diameter of the connecting shaft 3 is D5, and the diameter of the fixed shaft hole 14 and the rotating shaft hole 211 is D6.

[0063] In one embodiment, D1≤D4<D5<D6<D2<D3, that is, when assembling the furnace ear assembly 100, the first elastic ring 5 is first placed in the first annular groove 4, so that when the connecting shaft 3 passes through the fixed shaft hole 14 and / or the rotating shaft hole 211, the connecting shaft 3 passes through the first elastic ring 5, and the outer wall of the connecting shaft 3 presses the first elastic ring 5, so that the first elastic ring 5 is embedded in the first annular groove 4, to prevent the protruding first elastic ring 5 from hindering the movement of the connecting shaft 3; when the connecting shaft 3 moves to the point where the first annular groove 4 and the second annular groove 31 are directly opposite each other, the first elastic ring 5 is engaged in the second annular groove 31 under the action of elastic restoring force.

[0064] Furthermore, D1 < D4, which means that when the first elastic ring 5 is inserted into the second annular groove 31, the bottom of the second annular groove 31 squeezes the first elastic ring 5, causing the first elastic ring 5 to expand outward, which is more conducive to ensuring the stability of the first elastic ring 5 on the connecting shaft 3, thereby improving the reliability of the first elastic ring 5 in limiting the connecting shaft 3 and the corresponding fixed furnace ear 1 or rotating furnace ear.

[0065] D4-D1≤0.5mm, so as to ensure the compression effect while avoiding excessive compression of the first elastic ring 5 and causing damage.

[0066] In one embodiment, (D3-D2) > (D5-D1), meaning that when the first elastic ring 5 is not deformed, there is a distance d1 between the first elastic ring 5 and the bottom of the first annular groove 4, where d1 = (D3-D2) / 2. When the shaft wall of the connecting shaft 3 is pressed against the first elastic ring 5, the outer expansion of the inner annular wall of the first elastic ring 5 is a, where a = (D5-D1) / 2. By ensuring that (D3-D2) > (D5-D1), i.e., d1 > a, the gap between the first annular groove 4 and the first elastic ring 5 is sufficient to accommodate the deformed first elastic ring 5, preventing the first elastic ring 5 from being excessively compressed and damaged or hindering the movement of the connecting shaft 3, thus ensuring the reliability of the first elastic ring 5 and the operational reliability of the connecting shaft 3.

[0067] In one embodiment, the movable stove ear 2 includes two ear plate portions 21 arranged opposite to each other and spaced apart. Each ear plate portion 21 has a rotating shaft hole 211. The fixed stove ear 1 is sandwiched between the two ear plate portions 21. A support plate portion 22 is connected to the two ear plate portions 21. When the movable stove ear 2 is in the first position, the support plate portion 22 is horizontally positioned above the movable stove ear 2. That is, the support plate portion 22 is used to support the flat-bottomed pan. This arrangement enhances the overall structural strength and rigidity of the movable stove ear 2, improves its supporting performance, and thus improves the reliability and stability of the stove frame's support for the cookware. In other embodiments, the movable stove ear 2 can also be rotatably installed on one side of the support stove ear.

[0068] To improve the installation stability of the connecting shaft 3, in one embodiment, the walls of the fixed shaft hole 14 and the two rotating shaft holes 211 are provided with a first annular groove 4, thereby allowing the fixed furnace ear 1 and the movable furnace ear 2 to be axially positioned relative to the connecting shaft 3 by the first elastic ring 5, simplifying the installation.

[0069] In another embodiment, the connecting shaft 3 may have a limiting portion protruding radially from its first end, which abuts against one of the fixed furnace ear 1 or the movable furnace ear 2. The other of the fixed furnace ear 1 or the movable furnace ear 2 may have a first annular groove 4 to achieve axial limiting of the three. In yet another embodiment, only the rotating shaft hole 211 of the ear plate portion 21 may have the first annular groove 4.

[0070] In one embodiment, all the first annular grooves 4 are the same size, that is, all the first elastic rings 5 ​​are the same size, and all the second annular grooves 31 are the same size, so as to reduce the processing cost of the furnace ear assembly 100 and improve the interchangeability of the first elastic rings 5.

[0071] The first annular groove 4 and the second annular groove 31 are preferably arc-shaped bottom grooves to avoid squeezing damage to the first elastic ring 5 and improve the squeezing safety of the first elastic ring 5 by the bottom of the first annular groove 4 and the second annular groove 31. In one embodiment, the first annular groove 4 includes a rectangular groove portion and an arc-shaped groove portion. The arc-shaped groove portion is connected to the side of the rectangular groove portion away from the fixed shaft hole 14 or the rotating shaft hole 211. The diameter of the arc-shaped groove portion is the same as the groove width of the arc-shaped groove portion. This allows the diameter of the arc-shaped groove portion to match the diameter of the circular cross-section of the first elastic ring 5 while reducing the groove opening width of the first annular groove 4, reducing the probability of the first elastic ring 5 wobbling in the first annular groove 4, and improving the setting stability of the first elastic ring 5 in the first annular groove 4.

[0072] In one embodiment, the first elastic ring 5 is an open annular structure, and the center angle of the first elastic ring 5 is greater than 180°. By setting the first elastic ring 5 as an open annular structure, it is easier to achieve the outward expansion of the first elastic ring 5 as a whole, thereby improving the reliability of the first elastic ring 5 and reducing the probability of damage to the first elastic ring 5. The central angle of the first elastic element is preferably 220° to 320°.

[0073] To improve the smoothness of insertion of the connecting shaft 3 into the fixed shaft hole 14 and the rotating shaft hole 211, at least one end of the connecting shaft 3 is provided with a chamfer to better guide the connecting shaft 3 into the first elastic ring 5. The minimum diameter of the chamfer is less than D2.

[0074] like Figures 1 to 4 And 10 pictures to Figure 12As shown, a first support surface 221 is formed on the upper surface of the support plate portion 22. When the movable stove ear 2 is in the first position, the first support surface 221 is horizontally arranged to support the flat-bottomed pan. A second support surface 212 is formed on the side of the ear plate portion 21 away from the support plate portion 22. The second support surfaces 212 of the two ear plate portions 21 are coplanar. When the movable stove ear 2 is in the second position, the second support surface 212 is inclined from top to bottom along the direction of the center of the annular base 200 to support the arc-shaped bottomed pan 300.

[0075] In one embodiment, the ear plate portion 21 includes a first side portion and a second side portion disposed opposite to each other. A support plate portion 22 is connected between the first side portions of the two movable furnace ears 2, and the surface of the second side portion forms a second support surface 212. The distance between the first side portion and the second side portion gradually increases from the first end to the second end of the ear plate portion 21. The rotating shaft hole 211 is disposed near the second end of the ear plate portion 21, thereby reducing the width of the ear plate portion 21 at the first end while ensuring the opening size of the rotating shaft hole 211, thereby reducing the interference between the movable furnace ear 2 and the fixed furnace ear 1 and reducing the overall weight of the furnace frame. The second ends of the first side portion and the second side portion are connected by an arc-shaped side edge, and the axis of the arc-shaped side edge is coaxially disposed with the rotating shaft hole 211, thereby ensuring the overall strength and rigidity of the movable furnace ear 2 while reducing the size of the movable furnace ear 2.

[0076] In one embodiment, the extension length of the support plate portion 22 along the first side portion is less than the length of the first side portion. That is, the support plate portion 22 extends from the first end of the first side portion and is spaced apart from the second end of the first side portion, so that a through clearance space is formed between the second ends of the two first sides portion and between the two arc-shaped sides, so as to avoid the fixed furnace ear 1 during rotation.

[0077] In one embodiment, when the movable stove ear 2 is in the first position, the minimum distance between the support plate portion 22 and the center line of the annular base 200 is less than the minimum distance between the fixed stove ear 1 and the center line. This reduces the diameter of the circle formed by the inner ends of the multiple movable stove ears 2 when the movable stove ear 2 is in the first position, thereby making it more suitable for supporting frying pans of different sizes.

[0078] When the movable burner ear 2 is in the second position, the second support surface 212 extends from bottom to top away from the center line, and the first end of the movable burner ear 2 is higher than the fixed burner ear 1, with the support plate portion 22 located on the side of the second support surface 212 away from the center line. That is, the movable burner ear 2 rotates from the first position to the second position by flipping outwards. This arrangement increases the maximum distance between the second support surface 212 and the center line, thereby better accommodating the support of larger curved-bottom pots 300, allowing the stove rack to better accommodate curved-bottom pots 300 of different sizes.

[0079] To improve the stability of the movable furnace ear 2 in the first position, a first stop part 11 is provided on the fixed furnace ear 1. When the movable furnace ear 2 is in the first position, the first stop part 11 abuts against the movable furnace ear 2 to restrict the movable furnace ear 2 from rotating in a direction away from the second position.

[0080] The first stop portion 11 is a horizontal structure located on the upper end of the fixed burner ear 1. When the movable burner ear 2 is in the first position, the lower side of the support plate portion 22 is in contact with the first stop portion 11. This increases the contact area between the support plate portion 22 and the fixed burner ear 1, better restricting the fixed burner ear 1 from continuing to rotate downwards from the first position, ensuring that the first support surface 221 is horizontally positioned, thereby ensuring the stability and reliability of the support for the frying pan. When the movable burner ear 2 is in the first position, the width of the portion of the first stop portion 11 that is in contact with the support plate portion 22 in the radial direction of the annular base 200 is greater than 2 mm, further ensuring the stability of the support.

[0081] In one embodiment, a second stop portion 12 is provided on the fixed stove ear 1. When the movable stove ear 2 rotates to the second position, the movable stove ear 2 abuts against the second stop portion 12 to restrict the movable stove ear 2 from continuing to rotate in a direction away from the first position. At the same time, since the second support surface 212 extends from top to bottom in a direction towards the center line, the movable stove is restricted from flipping in a direction towards the first position under the pressure of the arc-shaped bottom pot 300. This allows the movable stove ear 2 to be stably maintained in the second position, improving the support stability and reliability of the arc-shaped bottom pot 300.

[0082] The second stop part 12 is provided on the side of the fixed furnace ear 1 away from the center line, and when the fixed furnace ear 1 is rotated to the second position, the lower end of the support plate part 22 is supported by the second stop part 12. This avoids the need to set up an additional structure that cooperates with the second stop part 12, simplifies the structure, and improves the performance.

[0083] In one embodiment, both the first stop portion 11 and the second stop portion 12 are horizontally arranged planar structures. The second stop portion 12 is lower than the first stop portion 11, and the second stop portion 12 and the first stop portion 11 are connected by an arc surface, with the opening of the arc surface facing the connecting shaft 3. This helps to prevent the support plate portion 22 from colliding with the fixed furnace ear 1 when the movable furnace ear 2 rotates, and also helps to prevent the arc-shaped bottom pot 300 from bumping into the fixed furnace ear 1.

[0084] The first stop part 11 is connected to a relief surface 13 on the side facing the center line. The relief surface 13 extends downward at an angle in the direction of the center line to avoid collision between the movable furnace ear 2 and the fixed furnace ear 1 when the movable furnace ear 2 flips inward, thereby improving the rotation reliability of the movable furnace ear 2.

[0085] It is worth noting that the annular base 200 can be a solid annular structure or a concentrating disk structure. The fixed furnace ear 1 can be welded to the annular base 200, or it can be connected to the annular base 200 by riveting or other methods that can achieve a stable connection. The specific structure of the annular base 200 and the connection structure of the fixed furnace ear 1 on the annular base 200 can be set with reference to the existing technology, which is not the focus of this utility model and will not be described in detail here.

[0086] This embodiment also provides a cooktop, including the aforementioned cooktop rack. The cooktop provided in this embodiment, by employing the aforementioned cooktop, allows for better compatibility with both flat-bottomed pans and curved-bottomed pans 300, while also improving the cooktop's ease of assembly and disassembly.

[0087] Example 2

[0088] This embodiment provides a stove rack and a stove including the stove rack. The basic structure of the stove rack provided in this embodiment is the same as that in the above embodiments, with only some differences in the settings. This embodiment will not repeat the contents that are the same as those in the above embodiments.

[0089] In this embodiment, D4 < D1 < D5 < D6 < D3 ≤ D2, meaning that when assembling the connecting shaft 3, the first elastic ring 5 is first fitted onto the connecting shaft 3 at the position corresponding to the second annular groove 31. Thus, when the connecting shaft 3 is inserted into the fixed shaft hole 14 and the rotating shaft hole 211, the hole walls of the fixed shaft hole 14 and the rotating shaft hole 211 compress the first elastic ring 5, causing the first elastic ring 5 to deform and sink into the second annular groove 31, so as to avoid the first elastic ring 5 affecting the insertion of the connecting shaft 3. When the connecting shaft 3 moves to the point where the second annular groove 31 and the first annular groove 4 are axially aligned, the compression of the hole wall on the first elastic ring 5 disappears, and the first elastic ring 5 recovers under its own elasticity, so that the upper part of the first elastic ring 5 is inserted into the first annular groove 4.

[0090] Furthermore, D3 < D2, which means that when the upper part of the first elastic ring 5 is engaged in the first annular groove 4, the groove wall of the first annular groove 4 presses against the first elastic ring 5, causing the first elastic ring 5 to tighten inward. This is more conducive to ensuring the stability of the first elastic ring 5 on the connecting shaft 3 and improving the reliability of the first elastic ring 5 in limiting the connecting shaft 3 and the corresponding fixed furnace ear 1 or rotating furnace ear. Furthermore, (D1-D4) > (D2-D6).

[0091] Furthermore, the second annular groove 31 includes a rectangular groove and an annular groove. The arc-shaped groove is connected to the side of the rectangular groove facing the center of the connecting shaft 3. The diameter of the arc-shaped groove is the same as the groove width of the arc-shaped groove. This allows the groove width of the second annular groove 31 to be reduced while the diameter of the arc-shaped groove matches the diameter of the circular cross-section of the first elastic ring 5. This reduces the probability of the first elastic ring 5 wobbling in the second annular groove 31 and improves the stability of the first elastic ring 5 in the first annular groove 4.

[0092] Example 3

[0093] This embodiment provides a stove rack and a stove including the stove rack. The basic structure of the stove rack provided in this embodiment is the same as that in the above embodiments, with only some differences in the settings. This embodiment will not repeat the contents that are the same as those in the above embodiments.

[0094] like Figure 13 and Figure 14 As shown, in this embodiment, the wall of the fixed shaft hole 14 is provided with a first annular groove 4, and the connecting shaft 3 is provided with two mounting annular grooves 32, which are located on opposite sides of the second annular groove 31. The furnace ear assembly 100 also includes a second elastic ring 6, which is provided in a one-to-one correspondence with the second annular groove 31, and the second elastic ring 6 is sleeved on the connecting shaft 3. When the second elastic ring 6 is not squeezed, the inner annular wall is located in the mounting annular groove 32 and the outer annular wall protrudes from the outer wall of the connecting shaft 3. The second elastic ring 6 can be squeezed into the mounting annular groove 32 so that the second elastic ring 6 can move across the mounting shaft hole or the fixed shaft hole 14. When the connecting shaft 3 is installed in place, both ends of the connecting shaft 3 are inserted into the two rotating shaft holes 211, and the second elastic ring 6 is located between the fixed furnace ear 1 and the ear plate portion 21 to restrict the ear plate portion 21 from approaching the fixed furnace ear 1.

[0095] This arrangement ensures that when the connecting shaft 3 is installed in place, the second elastic rings 6 are spaced apart between the ear plate portion 21 and the fixed furnace ear 1 and are in a free state. This allows the portion of the second elastic rings 6 protruding from the connecting shaft 3 to restrict the ear plate portion 21 from moving in the direction toward the fixed furnace ear 1. At the same time, since there are two ear plate portions 21, the two second elastic rings 6 cooperate with the two ear plate portions 21 to effectively limit the position of the movable furnace ear 2 in the axial direction of the connecting shaft 3, ensuring assembly reliability and stability and improving assembly efficiency.

[0096] The second elastic ring 6 has an inner diameter of D7 and an outer diameter of D8 when undeformed. The diameter corresponding to the bottom of the mounting ring groove 32 is D9, meaning the groove depth of the mounting ring groove 32 is d2, where d2 = (D5 - D9) / 2. D8 > D6 > D5 > D7 > D9, ensuring that the second elastic ring 6 can abut against the ear plate 21 when it is between the second ear plate portion 21 and the fixed furnace ear 1, thus restricting the movement of the ear plate portion 21. Furthermore, (D9 - D7) ≥ (D8 - D6).

[0097] In one embodiment, the maximum distance between the two mounting ring grooves 32 is equal to the distance between the two ear plate portions 21, thereby ensuring that when the connecting shaft 3 is installed in place, the ear plate portion 21 abuts or nearly abuts with the corresponding second elastic ring 6, improving the reliability of the limiting position.

[0098] The mounting groove 32 includes an arc-shaped groove and an arc-shaped groove. The arc-shaped groove is connected to the side of the rectangular groove facing the center line of the connecting shaft 3. The diameter of the arc-shaped groove is equal to the width of the rectangular groove. The diameter of the arc-shaped groove is equal to or slightly larger than the diameter of the cross-sectional circle of the second elastic ring 6.

[0099] It is worth noting that in this embodiment, the cooperation structure between the first elastic ring 5, the connecting shaft 3, and the fixed furnace ear 1 can refer to the structure in any of the above embodiments, and this embodiment does not limit it.

[0100] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0101] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
