Description

Technical Field

[0001] This utility model relates to a barbecue grill, and more particularly to a portable barbecue grill. Background Technology

[0002] With social development and the continuous improvement of people's living standards, outdoor activities have become increasingly popular in recent years, among which barbecuing is an indispensable part. To meet the market demand for outdoor barbecuing activities, portable barbecue grills have been invented.

[0003] For example, in Chinese utility model patent CN223111566U, the inventor discloses a folding oven, which includes a base assembly and side panel assemblies. The base assembly is formed by multiple fixed plates that surround and are fixed together to form a storage space with a certain volume. A charcoal mesh and an ash tray are detachably installed on the base assembly. The charcoal mesh is used to hold combustibles, and the ash tray is installed below the charcoal mesh to collect the ash from the combustion of the combustibles. The side panel assemblies are foldable and installed on the upper part of the base assembly. When unfolded, the side panels abut each other end to end to form the oven wall. A grill rack is detachably installed on the upper part of the oven wall for grilling. For food preparation, the side panel assembly can be folded and stored inside the storage space. The lower part of the base assembly is foldably equipped with a stand. One end of the stand is movably connected to the base assembly, and the other end forms a free end, which can be unfolded to support the ground. The side panel assembly has a first side panel, a second side panel, a third side panel, and a fourth side panel. The side panel assembly unfolds from the storage space, so that the two ends of the second side panel abut against the first side panel and the third side panel respectively. One end of the first side panel abuts against the second side panel, and the other end forms a free end. One end of the third side panel abuts against the second side panel, and the other end forms a free end. The two ends of the fourth side panel are movably connected to the first side panel and the third side panel respectively. The first, second, and third side panels, along with the fixed plate of the base assembly, are rotatably connected by a long strip hinge to form a hinge, allowing the side panel assembly to fold and rotate into the storage space, thus being completely stored within it. When the side panel assembly unfolds from the storage space and stands upright to form the oven wall, the ends of the first, second, and third side panels connected to the fixed plate, without hinges, can abut against each other, providing support from the fixed plate. The fourth side panel is detachably or rotatably connected to the first and third side panels, facilitating the addition and loading of charcoal into the oven. Existing folding ovens can be folded and unfolded, and when folded, they have a small size for easy portability.

[0004] However, existing folding ovens still have many drawbacks. The first, second, and third side panels of the side panel assembly are hinged to the fixed plate via long, narrow hinges. The fourth side panel is detachably or rotatably connected to the first and third side panels. This not only complicates the operation of the folding oven, but also causes the long, narrow hinges to deform in high-temperature environments, potentially leading to uneven rotation of the first, second, and third side panels relative to the fixed plate. Furthermore, the legs, when unfolded, rely solely on folding... The folding oven maintains stability due to its own weight. However, if a user accidentally kicks or bumps the legs, causing them to be subjected to an inward-tilting force, the legs can easily rotate, leading to the folding oven tilting and posing a safety hazard. Furthermore, the charcoal mesh is directly installed on the base assembly. During use, the charcoal mesh directly conducts heat to the base assembly and then to the side panel assembly. This means that the entire exterior of the folding oven will be at a high temperature, which can easily cause burns if the user accidentally touches it. Utility Model Content

[0005] One object of this invention is to provide a portable barbecue grill, wherein the portable barbecue grill has a small size when folded up so as to be easy to carry.

[0006] One object of this utility model is to provide a portable barbecue grill, wherein the oven box of the portable barbecue grill includes a lower oven body and an upper oven body that is movably fitted onto the lower oven body. When the portable barbecue grill is stored, the upper oven body moves downward relative to the lower oven body to reduce the size of the portable barbecue grill. When the portable barbecue grill is unfolded, the upper oven body moves upward relative to the lower oven body to make the oven box have a sufficiently large oven cavity.

[0007] One objective of this invention is to provide a portable barbecue grill. When the portable barbecue grill needs to be unfolded, the user only needs to pull the upper grill body upwards. Under the action of gravity, the upper grill body and the lower grill body will generate relative displacement. When the position of the second through hole in the upper grill body corresponds to the position of the first through hole in the lower grill body, the locking post of the locking assembly set in the lower grill body can automatically lock into the second through hole in the upper grill body, so as to ensure that the upper grill body and the lower grill body no longer move relative to each other, thereby keeping the portable barbecue grill in the unfolded state. When the portable barbecue grill needs to be stored, the user only needs to press the locking post inwards to make the locking post disengage from the second through hole in the upper grill body. Under the action of gravity, the upper grill body and the lower grill body will generate relative displacement.

The term "a" should not be construed as a limitation on the quantity.

[0049] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 15A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the portable barbecue grill includes a grill box 10, a lifting assembly 20, and a charcoal pan 30. The grill box 10 has a grill cavity 101. The bottom of the lifting assembly 20 is mounted on the grill box 10, and the lifting assembly 20 is located in the grill cavity 101 of the grill box 10. The charcoal pan 30 is disposed on the top of the lifting assembly 20. The height of the charcoal pan 30 is adjusted by the lifting assembly 20, thereby adjusting the distance between the charcoal pan 30 and the food supported by the edge of the top opening of the grill cavity 101 of the grill box 10, so as to adjust the barbecue temperature.

[0050] The charcoal brazier 30 can be placed directly on top of the lifting assembly 20. The charcoal brazier 30 rises and falls with the lifting assembly 20 to adjust the distance between the charcoal brazier 30 and the food supported by the edge of the top opening of the oven cavity 101 of the oven box 10, thereby adjusting the grilling temperature. (See attached...) Figures 1 to 15 In this specific example of the portable barbecue grill of the present invention, the charcoal basin 30 includes an ash tray 31 and a charcoal rack 32. The charcoal rack 32 is disposed above the ash tray 31 to form a uniform air chamber 33 of the charcoal basin 30 between the ash tray 31 and the charcoal rack 32. Charcoal can be placed on the charcoal rack 32, and the ash formed after the charcoal burns automatically falls into the ash tray 31.

[0051] It is understood that the side wall of the ash receiving tray 31 has multiple tray ventilation holes 311, and the charcoal frame 32 has multiple frame ventilation holes 321, which penetrate the upper and lower surfaces of the charcoal frame 32. The tray ventilation holes 311 of the ash receiving tray 31 and the frame ventilation holes 321 of the charcoal frame 32 are connected to the air equalization chamber 33 of the charcoal basin 30. The air from the external environment can reach the charcoal in sequence through the tray ventilation holes 311 of the ash receiving tray 31, the air equalization chamber 33, and the frame ventilation holes 321 of the charcoal frame 32, which is conducive to the combustion of the charcoal.

[0052] In the appendix Figures 1 to 15 In the portable barbecue grill of the present invention shown, the oven housing 10 includes a lower oven body 11 and an upper oven body 12. The upper oven body 12 is movably fitted onto the lower oven body 11, and the oven housing 10 forms the oven cavity 101 between the lower oven body 11 and the upper oven body 12. When the portable barbecue grill is stored, the upper oven body 12 moves downward relative to the lower oven body 11 to reduce the size of the portable barbecue grill, thereby making it easy to carry. When the portable barbecue grill is unfolded, the upper oven body 12 moves upward relative to the lower oven body 11 so that the oven housing 10 has a sufficiently large oven cavity 101.

[0053] Unlike existing technologies, in the attached Figures 1 to 15 In the portable barbecue grill of the present invention, the main body of the portable barbecue grill can be folded up and unfolded by moving the upper grill body 12 up and down relative to the lower grill body 11. This not only makes the operation of the portable barbecue grill more convenient, but also makes the portable barbecue grill more stable and reliable.

[0054] Furthermore, the top side of the lower furnace body 11 has at least one first through hole 111, and the bottom side of the upper furnace body 12 has at least one second through hole 121. When the upper furnace body 12 moves upward relative to the lower furnace body 11, the position of the second through hole 121 of the upper furnace body 12 and the position of the first through hole 111 of the lower furnace body 11 can correspond. When the upper furnace body 12 moves downward relative to the lower furnace body 11, the position of the second through hole 121 of the upper furnace body 12 and the position of the first through hole 111 of the lower furnace body 11 can be misaligned.

[0055] The portable barbecue grill includes at least one locking assembly 40, which includes a spring clip 41 and a locking post 42. The locking post 42 is disposed at one end of the spring clip 41, and the other end of the spring clip 41 is mounted to the lower grill body 11. In its natural state, the spring clip 41 holds the locking post 42 in a position passing through the first through hole 111 of the lower grill body 11. It is understood that the locking assembly 40 is in its natural state when no pressure is applied to the outer end of the locking post 42. When the portable barbecue grill is in the stowed state, the position of the second perforation 121 of the upper oven body 12 and the position of the first perforation 111 of the lower oven body 11 are misaligned. That is, the first perforation 111 of the lower oven body 11 corresponds to the inner wall of the upper oven body 12. The outer end of the locking post 42 abuts against the inner wall of the upper oven body 12. The inner wall of the upper oven body 12 applies pressure to the locking post 42 and keeps the spring piece 41 in a deformed state to accumulate elastic potential energy. When the portable barbecue grill needs to be unfolded, the upper oven body 12 moves upward until the position of the second perforation 121 of the upper oven body 12 corresponds to the position of the first perforation 111 of the lower oven body 11. During the process of restoring the initial state, the spring piece 41 causes the locking post 42 to automatically penetrate the second perforation 121 of the upper oven body 12. At this time, the portable barbecue grill can be switched to the unfolded state. Optionally, in other specific examples of the portable barbecue grill of this utility model, when the upper oven body 12 moves upward to the position of the second through hole 121 of the upper oven body 12 and the position of the first through hole 111 of the lower oven body 11, the spring piece 41 causes the locking post 42 to automatically pass through the second through hole 121 of the upper oven body 12.

[0056] In the appendix Figures 1 to 15 In this specific example of the portable barbecue grill of the present invention, the lower grill body 11 is a cuboid, which includes two lower side walls 112 and two lower end walls 113. The opposite ends of one lower side wall 112 extend to and are respectively installed at one end of the two lower end walls 113, and the opposite ends of the other lower side wall 112 extend to and are respectively installed at the other end of the two lower end walls 113. The opposite ends of the two lower side walls 112 each have a first perforation 111.

[0057] It is worth mentioning that the specific installation method of the ends of the lower side wall 112 and the lower end wall 113 is not limited in the portable barbecue grill of this utility model. For example, in the attached... Figures 1 to 15In this specific example of the portable barbecue grill of the present invention, the end of the lower sidewall 112 has a first folded edge 1121. After the first folded edge 1121 of the lower sidewall 112 is overlapped with the outer wall of the lower end wall 113, bolts are used to lock the first folded edge 1121 of the lower sidewall 112 and the lower end wall 113 to install the end of the lower sidewall 112 and the end of the lower end wall 113. Optionally, in other specific examples of the portable barbecue grill of the present invention, after the first folded edge 1121 of the lower sidewall 112 is overlapped with the outer wall of the lower end wall 113, the lower sidewall 112 and the lower end wall 113 can be welded to install the end of the lower sidewall 112 and the end of the lower end wall 113.

[0058] Accordingly, the upper furnace body 12 is a cuboid, which includes two upper side walls 122 and two upper end walls 123. The two opposite ends of one upper side wall 122 extend to and are respectively installed at one end of the two upper end walls 123, and the two opposite ends of the other upper side wall 122 extend to and are respectively installed at the other end of the two upper end walls 123. The two opposite ends of the two upper side walls 122 each have a second through hole 121.

[0059] It is worth mentioning that the specific installation method of the ends of the upper side wall 122 and the upper end wall 123 is not limited in the portable barbecue grill of this utility model. For example, in the attached... Figures 1 to 15 In this specific example of the portable barbecue grill of the present invention, the end of the upper sidewall 122 has a second folded edge 1221. After the second folded edge 1221 of the upper sidewall 122 is overlapped with the outer wall of the upper end wall 123, bolts are used to lock the second folded edge 1221 of the upper sidewall 122 and the upper end wall 123 to install the end of the upper sidewall 122 and the end of the upper end wall 123. Optionally, in other specific examples of the portable barbecue grill of the present invention, after the second folded edge 1221 of the upper sidewall 122 is overlapped with the outer wall of the upper end wall 123, the upper sidewall 122 and the upper end wall 123 can be welded to install the end of the upper sidewall 122 and the end of the upper end wall 123.

[0060] The number of the mounting components 40 is four, with one mounting component 40 located at each of the four corners of the lower oven body 11. One end of the spring tab 41 of each mounting component 40 is attached to one end of the lower end wall 113, and the other end of the spring tab 41 extends to a position abutting the end of the lower side wall 112, so that the locking post 42 is held in place through the first through hole 111 of the lower oven body 11. With this structure, after the portable barbecue grill is unfolded, the four mounting components 40 cooperate with each other to ensure the stability of the portable barbecue grill.

[0061] Preferably, the spring piece 41 includes a first arm 411, a second arm 412, and a third arm 413. The extension directions of the first arm 411 and the third arm 413 are perpendicular to each other. The second arm 412 extends obliquely between the first arm 411 and the third arm 413. The first arm 411 is attached to the lower end wall 113, and the end of the first arm 411 facing away from the second arm 412 is locked to the lower end wall 113. For example, bolts or rivets can be used to lock the end of the first arm 411 facing away from the second arm 412 to the lower end wall 113. The third arm 413 is attached to the lower side wall 112. A locking post 42 is provided at the end of the third arm 413 facing away from the second arm 412. For example, the locking post 42 can be riveted to the end of the third arm 413 facing away from the second arm 412. The spring piece 41 can be a sheet metal part, which is formed by bending a stainless steel sheet along a preset position to form the first arm 411, the second arm 412 and the third arm 413, so that the spring piece 41 has sufficient strength and elasticity.

[0062] Understandably, when the portable barbecue grill needs to be unfolded, the user only needs to pull the upper grill body 12 upwards. Under the action of gravity, the upper grill body 12 and the lower grill body 11 will generate relative displacement. When the upper grill body 12 moves to the position where the second through hole 121 of the upper grill body 12 corresponds to the position of the first through hole 111 of the lower grill body 11, the locking post 42 of the locking assembly 40 set in the lower grill body 11 can automatically lock into the second through hole 121 of the upper grill body 12 to ensure that the upper grill body 12 and the lower grill body 11 no longer move relative to each other, so that the portable barbecue grill can be kept in the unfolded state. When the portable barbecue grill needs to be stored, the user only needs to press the locking post 42 inwards to make the locking post 42 disengage from the second through hole 121 of the upper grill body 12. Under the action of gravity, the upper grill body 12 and the lower grill body 11 will generate relative displacement. Therefore, the portable grill of this invention can be easily operated, allowing the portable grill to switch between a stowed state and an unfolded state.

[0063] In the appendix Figures 1 to 15 In this specific example of the portable barbecue grill of the present invention, the upper grill body 12 is detachably mounted to the lower grill body 11, that is, the upper grill body 12 can be removed from the lower grill body 11 to facilitate separate cleaning of the upper grill body 12. Specifically, with the locking post 42 of the locking assembly 40 inserted into the second through hole 121 of the upper grill body 12, the user can remove the upper grill body 12 from the lower grill body 11 by pressing the locking post 42 inward to disengage it from the second through hole 121 and then pulling the upper grill body 12 upward.

[0064] Reference Appendix Figures 10 to 12 , Figure 14 and Figure 15The lifting assembly 20 includes a base frame 21, a top frame 22, two "X"-shaped first support arms 23, two "X"-shaped second support arms 24, two connecting plates 25, a screw 26, a threaded sleeve 27, and a hand crank 28. The base frame 21 and the top frame 22 are arranged vertically. The first support arm 23 has a first rotating side 231 and a first sliding side 232 relative to the first rotating side 231. The bottom and top of the first support arm 23 located on the first rotating side 231 are rotatably mounted to one end of the base frame 21 and one end of the top frame 22, respectively. The bottom and top of the first support arm 23 located on the first sliding side 232 are slidably mounted to this end of the base frame 21 and this end of the top frame 22, respectively. The second support arm 24 has a second rotating side 241 and a second sliding side 242 relative to the second rotating side 241. The bottom and top of the second support arm 24 located on the second rotating side 241 are rotatably mounted to the other end of the base frame 21 and the other end of the top frame 22, respectively. The bottom and top of the second support arm 24 located on the second sliding side 242 are slidably mounted to this end of the base frame 21 and this end of the top frame 22, respectively. The opposite ends of one connecting plate 25 are respectively mounted to the bottom of the first support arm 23 located on the first sliding side 241, and the opposite ends of the other connecting plate 25 are respectively mounted to the bottom of the second support arm 24 located on the second sliding side 242. The opposite ends of the screw 26 are respectively rotatably mounted to the base frame 21. The threaded sleeve 27 is fitted onto the screw 26 and fixedly mounted to the connecting plate 25. The hand crank 28 is mounted to one end of the screw 26.

[0065] The opposite ends of the base frame 21 are respectively mounted on the two lower end walls 113 of the lower furnace body 11 to mount the bottom of the lifting assembly 20 to the lower furnace body 11. For example, the bottom of the two lower end walls 113 of the lower furnace body 11 each has a third folded edge 1131. After the opposite ends of the base frame 21 are respectively abutted against the third folded edges 1131 of the two lower end walls 113 of the lower furnace body 11, bolts are used to lock the ends of the base frame 21 and the lower end walls 113 to mount the opposite ends of the base frame 21 to the two lower end walls 113 of the lower furnace body 11. Optionally, in other examples of the portable barbecue grill of the present invention, after the opposite ends of the base frame 21 are respectively attached to the third folded edges 1131 of the two lower end walls 113 of the lower oven body 11, the ends of the base frame 21 and the lower end walls 113 can be welded to install the opposite ends of the base frame 21 to the two lower end walls 113 of the lower oven body 11.

[0066] Reference Appendix Figure 1 , Figure 7 , Figure 10 and Figure 11 The lower end wall 113 of the lower furnace body 11 has a screw hole 1132. One end of the screw 26 extends through the screw hole 1132 of the lower furnace body 11 to the outside of the furnace box 10. The hand crank 28 is located on the outside of the furnace box 10 so that the user can crank the hand crank 28 on the outside of the furnace box 10.

[0067] When the user shakes the hand crank 28 in one direction to make the screw 26 rotate synchronously, the screw 26 and the threaded sleeve 27 cooperate to pull the bottom of the second sliding side 242 of the connecting plate 25 and the two second support arms 24 to the right. During this process, the top frame 22 moves upward to drive the charcoal basin 30 carried by the top frame 22 to move upward synchronously. At the same time, the top frame 22 pulls the two first support arms 23 to the right to make the shape of the first support arms 23 and the shape of the second support arms 24 consistent, so as to prevent the top frame 22 from tilting. When the user shakes the hand crank 28 in the opposite direction to make the screw 26 rotate synchronously, the screw 26 and the threaded sleeve 27 cooperate to push the bottom of the second sliding side 242 of the connecting plate 25 and the two second support arms 24 to the left. During this process, the top frame 22 moves downward to drive the charcoal basin 30 carried by the top frame 22 to move downward synchronously. At the same time, the top frame 22 pushes the two first support arms 23 to the left to make the shape of the first support arms 23 and the shape of the second support arms 24 consistent, so as to prevent the top frame 22 from tilting.

[0068] Furthermore, the base frame 21 includes two first base frame rods 211 and two second base frame rods 212. The two first base frame rods 211 are symmetrically arranged. The opposite ends of one second base frame rod 212 are respectively connected to one end of the two first base frame rods 211, and the opposite ends of the other second base frame rod 212 are respectively connected to the other end of the two first base frame rods 211. Each of the opposite ends of the first base frame rods 211 has a first base frame groove 2111 and a second base frame groove 2112. The top frame 22 includes two first top frame rods 221 and two second top frame rods 222. The two first top frame rods 221 are symmetrically arranged. The opposite ends of one second top frame rod 222 are respectively connected to one end of the two first top frame rods 221, and the opposite ends of the other second top frame rod 222 are respectively connected to the other end of the two first top frame rods 221. Each of the opposite ends of the first top frame rod 221 has a first top frame groove 2211 and a second top frame groove 2212. The positions of the first bottom frame groove 2111 of the first bottom frame rod 211 and the first top frame groove 2211 of the first top frame rod 221 correspond in the height direction, and the positions of the second bottom frame groove 2112 of the first bottom frame rod 211 and the second top frame groove 2212 of the second top frame rod 222 also correspond in the height direction. The bottom and top of the first sliding side 232 of the first support arm 23 each have a first sliding shaft 233, which extends into the first base frame groove 2111 of the first base frame rod 211 and the first top frame groove 2211 of the first top frame rod 221, respectively, so that the bottom and top of the first support arm 23 located on the first sliding side 232 are slidably mounted to one end of the base frame 21 and one end of the top frame 22, respectively. The bottom and top of the second sliding side 242 of the second support arm 24 each have a second sliding shaft 243, which extends into the second base frame groove 2112 of the first base frame rod 211 and the second top frame groove 2212 of the first top frame rod 221, respectively, so that the bottom and top of the second support arm 24 located on the second sliding side 242 are slidably mounted to one end of the base frame 21 and one end of the top frame 22, respectively.

[0069] The base frame 21 further includes a third base frame rod 213, the opposite ends of which are respectively installed in the middle of the two first base frame rods 211. The lifting assembly 20 further includes two bearing assemblies 29. One end of the screw 26 is installed in the third base frame rod 213 through one of the bearing assemblies 29, and the other end of the screw 26 is installed in a second base frame rod 212 through the other bearing assembly 29. Thus, the opposite ends of the screw 26 are rotatably installed in the base frame 21. Specifically, the bearing assembly 29 includes a bearing housing 291 and a bearing 292 installed in a seat hole 2911 of the bearing housing 291. The bearing 292 is fitted onto the end of the screw 26. The bearing housing 291 of one bearing assembly 29 can be locked to the third base rod 213 by a screw, so that one end of the screw 26 is installed on the third base rod 213 through the bearing assembly 29. The bearing housing 291 of the other bearing assembly 29 can be locked to the second base rod 212 by a screw, so that one end of the screw 26 is installed on the second base rod 212 through the bearing assembly 29.

[0070] Preferably, one of the upper end walls 123 of the upper oven body 12 has a clearance notch 1231 for clearance of the end of the screw 26 located outside the oven box 10, so that when the portable barbecue is in the stored state, the upper oven body 12 can be lowered to a lower position to reduce the size of the portable barbecue in the stored state as much as possible.

[0071] In the appendix Figures 1 to 15 In this specific example of the portable barbecue grill of the present invention, gaps exist between the charcoal brazier 30 and both the lower grill body 11 and the upper grill body 12. That is, there is no direct contact between the charcoal brazier 30 and the lower grill body 11 and the upper grill body 12. In this way, the lower grill body 11 and the upper grill body 12 can maintain a lower temperature during use, preventing burns even if the user accidentally touches them, thus ensuring safety. Simultaneously, because the temperature of the lower grill body 11 and the upper grill body 12 can be maintained at a relatively low angle, they are less prone to deformation, ensuring the reliability of the portable barbecue grill.

[0072] Reference Appendix Figures 2 to 9The portable barbecue grill includes a leg assembly 50, which includes an assembly plate 51, two support legs 52, and two hydraulic telescopic rods 53. One end of each of the two support legs 52 is rotatably mounted to opposite ends of the assembly plate 51. The bottom of one hydraulic telescopic rod 53 is rotatably mounted to the middle of the support leg 52, and the top of the hydraulic telescopic rod 53 is rotatably mounted to the end of the assembly plate 51 opposite to the end of the support leg 52. The assembly plate 51 is mounted to the bottom of the lower oven body 11, for example, bolts can be used to mount the assembly plate 51 to the bottom of the lower oven body 11. When the portable barbecue grill is in the stowed state, the hydraulic telescopic rod 53 can prevent the support leg 52 from automatically unfolding. When the portable barbecue grill is in the unfolded state, the hydraulic telescopic rod 53 supports the support leg 52. Even if the support leg 52 is kicked or touched and subjected to an inward flipping force, the hydraulic telescopic rod 53 can prevent the support leg 52 from flipping inward, thereby ensuring the stability of the portable barbecue grill.

[0073] Specifically, the bottom of one of the hydraulic telescopic rods 53 is rotatably mounted to the middle of the left support leg 52, and the top is rotatably mounted to the right end of the assembly plate 51. Correspondingly, the bottom of the other hydraulic telescopic rod 53 is rotatably mounted to the middle of the right support leg 52, and the top is rotatably mounted to the left end of the assembly plate 51. Thus, when the portable barbecue grill is in the unfolded state, the two hydraulic telescopic rods 53 are arranged in an "X" shape to ensure the stability of the portable barbecue grill.

[0074] Furthermore, the portable barbecue grill includes at least one shelf 60, one side of which is rotatably mounted to the top of the upper oven body 12. When the shelf 60 is unfolded, it can be supported by the upper oven body 12 to maintain a horizontal position. Specifically, each end of the pivot side of the shelf 60 has a supporting arm 61. When the shelf 60 is unfolded, each supporting arm 61 rests against the second folded edge 1221 of the upper sidewall 122 of the upper oven body 12, and is supported by the second folded edge 1221, thereby keeping the shelf 60 in a horizontal position.

[0075] Appendix Figures 16 to 19 The illustration shows a modified example of the portable barbecue grill of the present invention, with reference to the appendix. Figures 1 to 15 Unlike the portable barbecue grill shown, the attached Figures 16 to 19In this specific example of the portable barbecue grill shown, the lifting assembly 20 includes two links 210. The opposite ends of one link 210 are respectively connected to the first sliding shaft 233 of a first support arm 23 and the second sliding shaft 243 of a second support arm 24, so that the first support arm 23 and the second support arm 24 are linked together. The opposite ends of the other link 210 are respectively connected to the first sliding shaft 233 of another first support arm 23 and the second sliding shaft 243 of another second support arm 24, so that the first support arm 23 and the second support arm 24 are linked together.

[0076] When the user shakes the hand crank 28 in one direction to make the screw 26 rotate synchronously, the screw 26 and the threaded sleeve 27 cooperate to pull the bottom of the second sliding side 242 of the connecting plate 25 and the two second support arms 24 to the right. The two second support arms 24 pull the bottom of the first sliding side 232 of the two first support arms 23 to the right synchronously through the two connecting rods 210. During this process, the top frame 22 moves upward to drive the charcoal basin 30 carried by the top frame 22 to move upward synchronously. When the user cranks the hand crank 28 in the opposite direction, causing the screw 26 to rotate synchronously, the screw 26 and the threaded sleeve 27 cooperate to push the bottom of the second sliding side 242 of the connecting plate 25 and the two second support arms 24 to the left. The two second support arms 24, through the two connecting rods 210, synchronously push the bottom of the first sliding side 232 of the two first support arms 23 to the left. During this process, the top frame 22 moves downward, causing the charcoal basin 30, which is supported by the top frame 22, to move downward synchronously. During the cranking of the hand crank 28, the shapes of the first support arms 23 and the second support arms 24 remain consistent to prevent the top frame 22 from tilting.
