[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this utility model, the support bracket is fixedly installed on the body of the barbecue grill to support the grill body. The support bracket includes a support base and a locking mechanism. The support base is provided with a pin hole, so that components such as rollers and vehicle brackets that need to be connected to the barbecue grill can be provided with connecting pins that mate with the pin hole to connect to the grill body. When the connecting pin is inserted into the pin hole, the locking spring drives the locking plate to move along the guide groove, so that the locking plate is engaged in the annular groove on the periphery of the connecting pin, thereby axially limiting the connecting pin and locking the connecting pin, thus realizing the locking of the rollers and vehicle brackets.

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] This embodiment discloses a barbecue grill 1000, referencing... Figure 1The barbecue grill 1000 includes a grill body 100, a side plate 400, and a support bracket 200. The grill body 100 is used to heat and grill food. The support bracket 200 is fixedly installed at the bottom of the grill body 100 to support the grill body 100 and to connect the grill body 100 to other components, thereby enhancing the applicability of the barbecue grill 1000.

[0035] Reference Figure 2 and Figure 3 The support bracket 200 includes a support base 210 and a locking mechanism 220. The support base 210 is fixedly connected to the bottom of the furnace body 100. A pin hole 211 is provided on the side of the support base 210 away from the furnace body 100 for inserting a connecting pin 500. The locking mechanism 220 is provided on the support base 210 and is used to lock the connecting pin 500 inserted into the pin hole 211, thereby achieving a fixed connection between the pin and the support base 210.

[0036] Therefore, when it is necessary to connect the furnace body 100 to other components, a connecting pin 500 can be pre-installed on the other component. The connecting pin 500 can be inserted into the pin hole 211 and locked by the locking mechanism 220 to connect the furnace body 100 to other components. When it is necessary to disassemble the component, simply unlock the locking mechanism 220 and pull the connecting pin 500 out of the pin hole 211.

[0037] In this embodiment, the support bracket 200 includes multiple support seats 210, and correspondingly, multiple locking mechanisms 220 are also provided. The multiple support seats 210 are not arranged on the same straight line, so that the multiple support seats 210 can stably support the furnace body 100. Specifically, this embodiment shows that one support seat 210 is provided at each of the four corners of the bottom of the furnace body 100, that is, the four support seats 210 are arranged in a square, so that the support seats 210 provide more stable support for the furnace body 100. Furthermore, in other embodiments, the number of support seats 210 may be three or more.

[0038] Reference Figure 3 and Figure 4 In this embodiment, the support base 210 is a hollow shell structure to reduce the material consumption and weight of the support base 210, and further facilitate the handling of the barbecue grill 1000.

[0039] The pin hole 211 penetrates the bottom side of the support base 210 to form a downward opening for the insertion of the connecting pin 500. A first connecting cylinder 212 is provided inside the support base 210, and a second connecting cylinder 213 is sleeved on the first connecting cylinder 212. A guide seat 214 is connected above the second connecting cylinder 213. The pin hole 211 penetrates the first connecting cylinder 212 and the guide seat 214 so that the pin can pass through the first connecting cylinder 212 and the guide seat 214 to be smoothly inserted into the support base 210.

[0040] In this embodiment, the support base 210 includes a left support 201 and a right support 202 that are separately arranged, and both the left support 201 and the right support 202 are fixedly connected to the bottom of the furnace body 100. The left support 201 and the right support 202 fit together so that their bottoms surround and form the lower opening of the pin hole 211. When assembling the support base 210, the first connecting cylinder 212 can be inserted between the left support 201 and the right support 202, so that the inner cavity of the first connecting cylinder 212 is aligned with the lower opening between the left support 201 and the right support 202. Then, the second connecting cylinder 213 is sleeved on the outside of the first connecting cylinder 212, so that the part through which the pin hole 211 on the guide seat 214 passes is aligned with the inner cavity of the first connecting cylinder 212. Then, the locking mechanism 220 is installed, and the left support 201 and the right support 202 are fitted together. The lower opening between the left support 201 and the right support 202, the inner cavity of the first connecting cylinder 212, and the part through which the pin hole 211 on the guide seat 214 passes through are connected in sequence to form the pin hole 211. Finally, the left support 201 and the right support 202 are fixed to the bottom of the furnace body 100 respectively to realize the installation of the support base 210. This method allows the locking mechanism 220 to be installed in the left support 201 and the right support 202 first, and then the left support 201 and the right support 202 to be assembled, which facilitates the assembly of the locking mechanism 220.

[0041] In this embodiment, both the left support 201 and the right support 202 are fixedly connected to the bottom of the furnace body 100 by bolts. In other embodiments, the left support 201 and the right support 202 may also be connected to the bottom of the furnace body 100 by other suitable methods such as snap-fit, hot-melt connection, or integral molding.

[0042] In this embodiment, combined with Figures 1 to 3 Two connecting rods 600 are arranged parallel to each other at the bottom of the oven body 100. The connecting rods 600 extend along the length of the oven body 100 to the edge of the oven body 100, then bend upwards and connect to the side plate 400 of the barbecue oven 1000, supporting the side plate 400. Each connecting rod 600 passes through and is fixedly connected to two support seats 210. Specifically, each support seat 210 has a clearance hole 215 along the length of the connecting rod 600. The connecting rod 600 passes through two clearance holes 215 on the same straight line, and the portion of the connecting rod 600 passing through the clearance holes 215 is fixedly connected to the support seat 210 by bolts. Thus, the support seats 210 can also fix the connecting rod 600 to the oven body 100, making the structure of the barbecue oven 1000 more reasonable.

[0043] The connecting rod 600 has a notch 610 at the part where it passes through the clearance hole 215, so as to allow the locking mechanism 220 and the connecting pin 500 inside the support base 210 to be cleared. This makes the height of the support base 210 less important, and makes the structure of the barbecue grill 1000 more compact and reasonable.

[0044] Reference Figure 3 and Figure 4 The locking mechanism 220 includes a locking plate 221, a locking button 222, and a locking spring 223. A guide groove 216 with a vertical pin hole 211 is provided inside the support base 210. A guide hole 218 is opened on the side of the support base 210, directly opposite the guide groove 216. The locking plate 221 is slidably disposed within the guide groove 216. The locking button 222 is connected to the locking plate 221 and protrudes from the guide hole 218.

[0045] A locking spring 223 engages with a locking plate 221 to drive the locking plate 221 to move relative to the pin hole 211. A ring groove 510 is formed around the periphery of the connecting pin 500. When the connecting pin 500 is inserted into the pin hole 211, the locking spring 223 drives the locking plate 221 to move along a guide groove 216, thereby at least partially engaging the locking plate 221 into the ring groove 510 around the connecting pin 500, axially limiting the connecting pin 500 and locking it. When the locking button 222 is pressed, the locking plate 221 overcomes the spring force of the locking spring 223 and disengages from the ring groove 510 of the connecting pin 500, releasing the locking of the connecting pin 500. At this time, the connecting pin 500 can be pulled out, disconnecting the furnace body 100 from the component with the connecting pin 500.

[0046] In this embodiment, the upper part of the connecting pin 500 located in its annular groove 510 is conical, so that when the connecting pin 500 is inserted into the pin hole 211, the conical end surface presses against the locking plate 221, causing the locking plate 221 to compress the locking spring 223 and align the locking hole 2211 with the pin hole 211. After the connecting pin 500 is fully inserted, the conical part leaves the locking plate 221, and the locking plate 221 moves under the action of the locking spring 223 and is locked into the annular groove 510. Thus, the connecting pin 500 can be smoothly inserted into the locking hole 2211 without pressing the locking button 222, which is convenient for user operation.

[0047] In this embodiment, the guide groove 216 is formed in the guide seat 214 and communicates with the pin hole 211. The locking plate 221 slides along the path of the guide groove 216 perpendicular to the pin hole 211, so that the locking plate 221 can be engaged or disengaged from the annular groove 510 of the connecting pin 500.

[0048] The locking plate 221 has a locking hole 2211. When the locking button 222 is pressed, the locking hole 2211 is aligned with the pin hole 211 so that the connecting pin 500 can pass through the pin hole 211 and the locking hole 2211. When the locking button 222 is released, the locking hole 2211 and the pin hole 211 are misaligned (i.e., the axes of the locking hole 2211 and the pin hole 211 do not coincide), so that the locking plate 221 is engaged in the annular groove 510 of the connecting pin 500 at the edge of the locking hole 2211 to lock the connecting pin 500. This structure makes it less likely for the locking plate 221 to interfere with the normal insertion and removal movement of the connecting pin 500, and at the same time, it enables the locking plate 221 to stably lock the connecting pin 500.

[0049] In this embodiment, the locking spring 223 includes a compression spring that abuts against the end of the locking plate 221 away from the locking button 222. The compression spring provides a force to the locking plate 221 toward the locking button 222, so that when the locking button 222 is not pressed, it drives the locking plate 221 to move toward the side away from the compression spring, causing the locking hole 2211 to be misaligned with the pin hole 211. Alternatively, in other embodiments, the locking spring 223 may also be a tension spring, with one end connected to the end of the locking plate 221 toward the locking button 222 to provide a force to the locking plate 221 toward the locking button 222.

[0050] In this embodiment, a spring seat 217 is provided inside the support base 210. The spring seat 217 abuts against the compression spring, and the middle part of the spring seat 217 protrudes towards the locking plate 221 and is inserted into the end of the compression spring away from the locking plate 221. A limiting protrusion 2212 protrudes from the end of the locking plate 221 away from the locking button 222, and the limiting protrusion 2212 is inserted into the end of the compression spring away from the spring seat 217. The two ends of the compression spring are respectively inserted into the spring seat 217 and the limiting protrusion 2212 to stably limit the compression spring between the locking plate 221 and the spring seat 217, so that the compression spring is more stable when it deforms to provide elastic force.

[0051] A retaining flange 2221 is provided around the periphery of the locking button 222. The retaining flange 2221 is located inside the support base 210, and the outer diameter of the retaining flange 2221 is larger than the inner diameter of the guide hole 218. Thus, the retaining flange 2221 limits the locking button 222 within the support base 210, preventing the locking button 222 from dislodging from the guide hole 218, thereby ensuring that the locking mechanism 220 is stably assembled within the support base 210.

[0052] Reference Figures 2 to 5 This embodiment also discloses a roller 300, which includes a wheel body 310, a wheel seat 320, and a connecting pin 500 for connecting to a support base 210. The wheel body 310 is rotatably connected to the lower part of the wheel seat 320, and the connecting pin 500 is fixedly connected to the upper part of the wheel seat 320.

[0053] In this embodiment, the roller 300 can be quickly connected to the oven body 100 through the insertion and engagement of the connecting pin 500 with the support base 210 and the locking mechanism 220. When the locking button 222 is pressed, the connecting pin 500 can also be quickly pulled out from the pin hole 211, thereby removing the roller 300 from the support bracket 200. This makes it convenient to connect the roller 300 for transporting the barbecue oven 1000 after it arrives at its destination, or to remove the roller 300 after the barbecue oven 1000 has been used, making the operation more convenient and effortless for the user.

[0054] Reference Figure 6 This embodiment also discloses a vehicle-mounted bracket 2000, which includes a bracket body 2100 and connecting pins 500. The bracket body 2100 is used to fix to the rear of a vehicle, and the connecting pins 500 are connected to the top of the bracket body 2100. Four connecting pins 500 are provided corresponding to the support base 210. The connecting pins 500 can be inserted into the pin holes 211 of the support base 210, and are locked in the annular grooves 510 of the connecting pins 500 by the locking plate 221 of the locking mechanism 220. This facilitates the assembly and disassembly of the vehicle-mounted bracket 2000 from the grill body 100, makes it convenient for the grill 1000 to be fixed to the vehicle and transported by vehicle, and facilitates removal from the vehicle-mounted bracket 2000 after reaching the destination.

[0055] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
