Description

Technical Field

[0001] This utility model relates to the technical field of gas-fired grill equipment, and in particular to a gas-fired barbecue grill. Background Technology

[0002] A gas-fired barbecue grill is a grilling device that uses liquefied petroleum gas (LPG) or natural gas to generate heat through combustion, heating with an open flame. A gas-fired barbecue grill uses multiple burners, which are fixed to a mounting bracket to form a burner assembly, which is then installed inside the grill body. Gas-fired barbecue grills require regular cleaning to prevent grease residue from causing malfunctions. To facilitate the disassembly and reassembly of the burner assembly, existing technology provides a gas-fired barbecue grill that uses connecting studs and locking nuts to fix the burner assembly. The grill body has threaded holes, and the connecting studs are threaded into these holes and fixed to the grill body. The upper end of the connecting stud passes through the burner assembly, and the locking nut is threaded into the upper part of the connecting stud, thus fixing the burner assembly to the grill body. However, when disassembling and reassembling the burner assembly, removing the locking nut can easily loosen the entire connecting stud, which is easily lost after being removed from the grill body. Furthermore, reinstalling the burner assembly requires reinstalling the connecting stud, making the disassembly and reassembly process cumbersome and affecting cleaning efficiency. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a gas-fired barbecue grill that can solve the problem of connection reliability of the mounting studs on the grill body, and will not cause the mounting studs to loosen or be lost when disassembling the press-fit nut, thereby improving the ease of disassembly and assembly of the burner assembly.

[0004] The above-mentioned technical problems are solved by the following technical solutions:

[0005] A gas-fired barbecue grill, comprising:

[0006] The furnace body has a combustion chamber and is provided with mounting threaded holes;

[0007] A burner assembly is disposed within the combustion chamber. The burner assembly includes a mounting bracket and at least two burners spaced apart on the mounting bracket. The mounting bracket is provided with connecting lugs.

[0008] The mounting stud includes a first threaded section and a second threaded section. The major diameter of the first threaded section is larger than that of the second threaded section. The first threaded section and the second threaded section have the same direction of rotation. The mounting stud passes through the connecting lug, and the first threaded section is threaded into the mounting threaded hole.

[0009] A press-fit nut, which is threadedly connected to the second threaded section and presses against the connecting lug.

[0010] The gas-fired barbecue grill described in this utility model has the following advantages compared with the prior art:

[0011] The gas-fired barbecue grill features mounting studs and press-fit nuts. The mounting stud includes a first threaded section and a second threaded section, with the major diameter of the first threaded section being larger than that of the second threaded section. The first and second threaded sections have the same direction of rotation. The first threaded section is threaded into the mounting threaded hole in the grill body. The press-fit nut is threaded into the second threaded section and presses against the burner assembly. The grill body has mounting threaded holes. During assembly, the first threaded section is threaded into the mounting threaded hole, and then the press-fit nut is threaded into the second threaded section. During tightening of the press-fit nut, because the first and second threaded sections have the same direction of rotation, the first threaded section will not move, and the press-fit nut locks the second threaded section tightly against the connecting lug of the burner assembly, thus fixing the burner assembly in place. Furthermore, the mounting stud passes through the connecting lug of the burner assembly, acting as a limiter and improving the installation position accuracy of the burner assembly. When the burner assembly needs to be disassembled, the press-fit nut is turned in the reverse direction. Because the torque applied by the press-fit nut to the second threaded section is less than the torque required to loosen the first threaded section from the mounting threaded hole, it will not cause the first threaded section to rotate. The press-fit nut can then be loosened from the second threaded section, allowing the burner assembly to detach from the oven body. During the installation and removal of the press-fit nut, the mounting studs remain fixed to the oven body and will not loosen, thus avoiding the risk of loss due to stud removal and eliminating the need for reinstallation. The disassembly and assembly of the burner assembly are relatively convenient, improving the ease of cleaning the gas grill.

[0012] In one embodiment, the mounting stud further includes a cylindrical section, with the two ends of the first threaded section connected to the cylindrical section and the second threaded section, respectively.

[0013] In one embodiment, the outer diameter of the light column segment is smaller than the major diameter of the first threaded segment.

[0014] In one embodiment, the length ratio of the first threaded segment to the second threaded segment is 1:1 to 1.5:1; and / or,

[0015] The depth of the mounting threaded hole is greater than the length of the first threaded segment.

[0016] In one embodiment, the major diameter of the first threaded segment is 5.85mm to 5.95mm, and the major diameter of the second threaded segment is 5.73mm to 5.83mm.

[0017] In one embodiment, a protruding mounting seat is provided inside the combustion chamber, the mounting threaded hole is formed on the mounting seat, and the lower side of the connecting lug is attached to the upper surface of the mounting seat.

[0018] In one embodiment, the connecting ear has a locking notch, the mounting stud passes through the locking notch, and the locking notch at least partially surrounds the mounting stud in the circumferential direction.

[0019] In one embodiment, the burner assembly includes two mounting brackets that are parallel to each other and spaced apart. Each mounting bracket has a connecting lug at both ends. The furnace body has four mounting threaded holes, and four mounting studs and four press-fit nuts are provided accordingly. The four mounting threaded holes and the four connecting lugs correspond one-to-one.

[0020] In one embodiment, the second threaded segment has a mounting groove at its top end away from the first threaded segment. The mounting groove is a slotted groove or an internal hexagonal groove.

[0021] In one embodiment, the press-fit nut has a handle. Attached Figure Description

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] This utility model provides a gas-fired barbecue grill that solves the problem of fixing studs on the grill body, reduces the processing cost of the gas-fired barbecue grill, and improves the ease of disassembly and assembly of the burner assembly.

[0034] like Figures 1 to 3As shown, the gas-fired barbecue grill includes a grill body 1, a burner assembly 2, mounting studs 3, and a press-fit nut 4. The grill body 1 has a combustion chamber 11 and a threaded mounting hole 12. The burner assembly 2 is disposed within the combustion chamber 11; the burner assembly 2 includes a mounting bracket 21 and at least two burners 22 spaced apart on the mounting bracket 21. The mounting bracket 21 has connecting lugs 211. The mounting stud 3 includes a first threaded section 31 and a second threaded section 32. The major diameter of the first threaded section 31 is larger than the major diameter of the second threaded section 32. The first threaded section 31 and the second threaded section 32 have the same direction of rotation. The first threaded section 31 is threaded into the threaded mounting hole 12. The press-fit nut 4 is threaded into the second threaded section 32 and presses against the top of the connecting lug 211. The furnace body 1 has a threaded mounting hole 12. During assembly, the first threaded section 31 can be threaded into the threaded mounting hole 12, and then the press-fit nut 4 can be threaded into the second threaded section 32. During the tightening of the press-fit nut 4, since the first threaded section 31 and the second threaded section 32 rotate in the same direction, the first threaded section 31 will not move. The press-fit nut 4 can lock the second threaded section 32 and press it tightly onto the connecting lug 211, thus fixing the burner assembly 2. Moreover, the mounting stud 3 passes through the connecting lug 211, and the mounting stud 3 acts as a limit, improving the installation position accuracy of the burner assembly 2. When it is necessary to disassemble the burner assembly 2, the press-fit nut 4 is turned in the opposite direction. Since the torque applied by the press-fit nut 4 to the second threaded section 32 is less than the torque required to loosen the first threaded section 31 from the threaded mounting hole 12, it will not cause the first threaded section 31 to rotate. The press-fit nut 4 can be loosened from the second threaded section 32, and the burner assembly 2 can be detached from the furnace body 1. During the installation and removal of the press-fit nut 4, the mounting stud 3 remains fixed to the oven body 1 without loosening, thus avoiding the risk of loss due to removal and eliminating the need for reinstallation. The burner assembly 2 is easy to install and remove, improving the cleaning convenience of the gas grill. Furthermore, the mounting stud 3 does not require the use of high-temperature thread-locking agents, reducing the processing cost of the gas grill. In one embodiment, the mounting stud 3 also includes a smooth cylindrical section 33, with the two ends of the first threaded section 31 connected to the smooth cylindrical section 33 and the second threaded section 32, respectively. On one hand, when the mounting stud 3 is aligned with the mounting threaded hole 12, the smooth cylindrical section 33 acts as a guide, reducing damage to the threads of the first threaded section 31. On the other hand, during the processing of the mounting stud 3, the smooth cylindrical section 33 is used for clamping, facilitating processing.

[0035] like Figure 4 As shown in the figure, it can be seen that the major diameter D1 of the first threaded section 31 is greater than the major diameter D2 of the second threaded section 32.

[0036] To simplify the machining process and reduce costs, the first threaded section 31 and the second threaded section 32 are identical in terms of minor diameter, pitch, and thread angle, except for the difference in their major diameters. For the torque required to tighten the installation stud 3, all other parameters are equal, and the torque is directly proportional to the major diameter. The major diameter of the first threaded section 31 is greater than that of the second threaded section 32, ensuring that the first threaded section 31 remains threadedly connected to the furnace body 1 during the loosening of the press-fit nut 4.

[0037] The outer diameter of the smooth column section 33 is smaller than the major diameter of the first threaded section 31, which provides better guidance and makes it easier for the smooth column section 33 to enter the mounting threaded hole 12. Moreover, it can reduce the risk of the smooth column section 33 colliding with the internal thread of the mounting threaded hole 12.

[0038] To facilitate the screwing of the first threaded section 31 into the mounting threaded hole 12, the second threaded section 32 has a mounting groove 34 at its top end away from the first threaded section 31. The mounting groove 34 is either a slotted groove or an internal hexagonal groove. Figure 5 As shown, the mounting slot 34 in the figure is an internal hexagonal slot. An internal hexagonal screwdriver can be inserted into the mounting slot 34, and the mounting stud 3 can be rotated to lock the mounting stud 3 into the mounting threaded hole 12. In other embodiments, the mounting slot 34 can also be a flat slot. A flathead screwdriver can be inserted into the mounting slot 34, and the mounting stud 3 can be rotated.

[0039] In one embodiment, the length ratio of the first threaded segment 31 to the second threaded segment 32 is 1:1 to 1.5:1. Exemplarily, the lengths of the first threaded segment 31 and the second threaded segment 32 are equal, or the length of the first threaded segment 31 is 1.1 times, 1.2 times, 1.3 times, 1.5 times, or any other value between 1 and 1.5 times the length of the second threaded segment 32. Appropriately increasing the length of the first threaded segment 31 helps to increase the reliability of the connection between the first threaded segment 31 and the furnace body 1.

[0040] The depth of the mounting threaded hole 12 is greater than the length of the first threaded section 31. After the mounting stud 3 is threaded into the mounting threaded hole 12, the first threaded section 31 will not protrude out of the mounting threaded hole 12. In this way, during the installation of the press-fit nut 4, the press-fit nut 4 will not contact the first threaded section 31, thus avoiding the first threaded section 31 being too long and interfering with the press-fit nut 4, which would affect the reliability of the press-fit nut 4 in pressing the burner assembly 2.

[0041] In one embodiment, the major diameter of the first threaded segment 31 is 5.85mm to 5.95mm, and the major diameter of the second threaded segment 32 is 5.73mm to 5.83mm. The major diameters of the first threaded segment 31 and the second threaded segment 32 are set within this range, with the major diameter of the first threaded segment 31 always being larger than that of the second threaded segment 32. Furthermore, the difference between the major diameters of the first threaded segment 31 and the second threaded segment 32 is small, which can reduce the difficulty of the machining process. For example, the major diameter of the first threaded segment 31 is 5.85mm, 5.86mm, 5.9mm, 5.95mm, or any other value within the range of 5.85mm to 5.95mm; the major diameter of the second threaded segment 32 is 5.73mm, 5.74mm, 5.75mm, 5.83mm, or any other value within the range of 5.73mm to 5.83mm.

[0042] In one embodiment, a protruding mounting base 13 is provided inside the combustion chamber 11, and a mounting threaded hole 12 is formed on the mounting base 13. The lower side of the connecting ear 211 is attached to the upper surface of the mounting base 13, and the press-fit nut 4 is pressed against the upper surface of the connecting ear 211. The connecting ear 211 is sandwiched between the mounting base 13 and the press-fit nut 4.

[0043] The connecting ear 211 has a locking notch 212, and the mounting stud 3 passes through the locking notch 212. The locking notch 212 at least partially surrounds the mounting stud 3 in the circumferential direction. For example, as shown... Figure 5 As shown in the figure, the locking notch 212 can wrap around the side of the mounting stud 3 within a 180° range. On the one hand, the structure of the locking notch 212 improves the accuracy of the mounting stud 3 in limiting the burner assembly 2, restricting the movement of the burner assembly 2 in the horizontal plane from multiple directions, and reducing the risk of the burner assembly 2 moving during the installation of the press-fit nut 4; on the other hand, the structure of the locking notch 212 makes the contact area between the press-fit nut 4 and the upper surface of the connecting lug 211 larger, forming a greater clamping force, and making the fixation of the burner assembly 2 more reliable.

[0044] The furnace body 1 has four threaded mounting holes 12, corresponding to four mounting studs 3 and four press-fit nuts 4, with each stud and nut in a one-to-one correspondence. The four threaded mounting holes 12 are located at the four corners of the burner assembly 2, thus constraining the movement of the burner assembly 2 in any direction within the horizontal plane. Figure 1As shown, the burner assembly 2 includes two parallel mounting brackets 21 and four burners 22 mounted on the mounting brackets 21. The burners 22 are perpendicular to the mounting brackets 21 and are spaced apart along the length of the mounting brackets 21. Each mounting bracket 21 has a locking notch 212 at both ends, and the two ends of the two mounting brackets 21 correspond to four mounting studs 3, thus constraining the position of the burner assembly 2 from the four corners. When the four locking notches 212 are aligned with the four mounting studs 3, the position of the burner assembly 2 in the horizontal plane is fully constrained.

[0045] To further improve ease of assembly and disassembly, the press-fit nut 4 has a handle 41. For example, as... Figure 5 As shown, in one embodiment, the handle 41 is disposed on the top of the nut body 42. The handle 41 is a block structure with a certain thickness and a length greater than the outer diameter of the nut body 42, which is convenient for the operator to hold. The nut 4 can be assembled and disassembled by hand-tightening without the need for special tools, which is convenient for operation.

[0046] 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.

[0047] 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.
