DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1: Figure 1-10 As shown, a cooking integrated mobile platform includes a box, which includes a box body 1 and a box cover 11 that are hinged to each other, and a stove 12 is arranged inside the box cover 11, characterized in that: the shielding side of the box body 1 other than the box cover 11 after flipping is provided with an expansion mechanism; The expansion mechanism includes an expansion board 2, a buckle strip 21, a connecting strip 22 and a locking assembly. The buckle strips 21 and the connecting strips 22 are provided in a plurality and are relatively arranged on four sides of the expansion board 2. One buckle strip 21 is provided on the side of the box body 1, and the locking assembly is provided on the expansion board 2. The locking assembly includes a connecting pin and a self-closing pin, the self-closing pin is arranged in the middle of the buckle strip 21, and the connecting pin is arranged in the connecting strip 22. An air pump is arranged in the box body 1, and the output end of the air pump is connected with the self-closing pin air path 23 in the buckle strip 21 arranged on the box body 1 through a conduit. An air path 23 is opened in the expansion plate 2, and the air path 23 connects the connecting pin and the self-closing pin. A bypass 24 corresponding to the self-closing pin is opened between the connecting strip 22 and the expansion plate 2, and a one-way air intake valve 25 and a sealing ring 26 are arranged in the bypass 24, and the sealing ring 26 is closer to the opening of the bypass 24 than the one-way air intake valve 25.

[0028] When the device is used outdoors, in the initial state of the device, the box body 1 and the box cover 11 are buckled together and connected by structures such as buckles and locks to form a closed box body 1. With the moving wheels provided at the lower end of the box body 1 and the handles on the side, the device can be conveniently towed and carried until it reaches the designated position. At this time, the operating table can be freely assembled through the expansion mechanism according to the number of people in the outdoor activities and the size of the venue. The stove 12 is used to meet the need for the container to be stably suspended when the portable gas stove is used outdoors, and the induction cooker 13 can be raised, supported and stabilized by the bracket in the box cover 11 when an additional generator is provided, so as to meet the need for cooking with the induction cooker 13, wherein the induction cooker 13 is a common DC induction cooker outdoors; During assembly, align the connecting strip 22 of the expansion board 2 with the side of the buckle strip 21 and slide it in. Of course, the two expansion boards 2 can also be connected to each other through the buckle strips 21 and the connecting strips 22, so that the assembly between the box body 1 and the expansion board 2 or multiple expansion boards 2 can be completed. Since the buckle strips 21 and the connecting strips 22 are arranged on the expansion board 2 in a relative side arrangement, multiple expansion boards 2 can be flexibly combined according to actual needs to form a variety of splicing table structures such as long rectangles, squares, L shapes, etc. Furthermore, when multiple expansion boards 2 are spliced ​​and assembled, compressed air is output by opening the air pump in the box body 1. At this time, the compressed air is input into the self-closing pin on the box body 1 through the conduit. The self-closing pin is activated by the pneumatic pressure and inputs air into the air path 23 of the connected expansion board 2 to drive the connecting pin in the expansion board 2 to form a lock. At the same time, multiple expansion boards 2 can be locked at the same time, so that the splicing and fixing can be completed quickly, so that the splicing combination can be completed more conveniently and quickly.

[0029] The buckle strip 21 is a spherical cover structure with an opening, and the connecting strip 22 is a cylindrical structure. The diameter of the cylindrical structure of the connecting strip 22 matches the inner diameter of the spherical cover structure of the buckle strip 21 .

[0030] The structure of the buckle strip 21 and the connecting strip 22 can not only facilitate the connection, but also increase the force-bearing area, so that it can be more stable when supporting heavy objects placed on the expansion board 2.

[0031] The self-closing pin includes an insertion rod 3, a first limiting plate 31, a first spring 32, a sliding cover 33, a second spring 34 and a second limiting plate 35. A first step cavity 36 communicating with the ball cover structure is opened in the buckle strip 21, the first limiting plate 31 is slidingly sealed in the first step cavity 36, the insertion rod 3 is concentrically connected with the first limiting plate 31, the second limiting plate 35 is arranged in the middle of the insertion rod 3, the sliding cover 33 is slidingly sealed with an end of the insertion rod 3 away from the first limiting plate 31 through a sliding groove, the second spring 34 is sleeved on the insertion rod 3 and is located between the sliding cover 33 and the second limiting plate 35, a clamping ring 37 is provided in the middle of the first step, the first spring 32 is sleeved on the insertion rod 3 and is located between the first limiting plate 31 and the clamping ring 37, an air supply channel 38 is opened at the axis of the insertion rod 3, one end of the air supply channel 38 is opened and communicated with the air pump, and the other end of the air supply channel 38 is opened at the side of the insertion rod 3 and corresponds to the sliding cover 33, and the inner ring diameter of the sealing ring 26 matches the insertion rod 3.

[0032] The connecting pin includes a third limit plate 4, a limit rod 41 and a third spring 42. A second step cavity 43 connected to the air path 23 is commonly opened between the expansion plate 2 and the connecting strip 22. The third limit plate 4 is slidingly sealed in the second step cavity 43. The limit rod 41 is concentrically connected to the third limit plate 4. The third spring 42 is sleeved on the limit rod 41 and is located in the second step cavity 43. The buckle strip 21 is opened with a socket 44 matching the limit rod 41.

[0033] When the air pump outputs compressed air to the self-closing pin, since the opening of the air supply passage 38 of the plug rod 3 is closed by the sliding cover 33 in the initial state, the air pressure will directly push the plug rod 3 to move in the first step cavity 36 to the bypass 24 of the corresponding connecting strip 22. At this time, the second spring 34 sleeved on the plug rod 3 is blocked by the second limiting plate 35 and the sealing ring 26 in the bypass 24, and will slide along the axial direction of the plug rod 3 and the opposite direction of movement. At this time, the plug rod 3 will extend into the sealing ring 26, wherein the inner ring wall of the sealing ring 26 is provided with a sealing rubber ring, until the opening of the air supply passage 38 on the plug rod 3 extends between the sealing ring 26 and the one-way air inlet valve 25, the compressed air will be input into the air path 23 of the expansion plate 2 through the air supply passage 38, and then the limiting rod 41 in the connecting pin is driven by the compressed air to slide and extend into the corresponding socket 44 of the buckle strip 21, completing the displacement limit; When the compressed air of the air pump stops being delivered, the plug rod 3 of the self-closing pin is reset by the first spring 32, and the sliding cover 33 is reset by the second spring 34 to be completely received in the first step cavity 36. This method can facilitate the sliding assembly between the buckle strip 21 and the connecting strip 22 in the early stage to avoid the obstruction of the parts, and can form a more closed air path 23 when delivering air, reduce gas leakage and improve the connection efficiency. Furthermore, since the air supply duct 38 on the self-closing pin must be exposed by abutting against the sealing ring 26 on the connecting strip 22, when the snap-fit ​​strip 21 of the expansion plate 2 is not connected to the connecting strip 22, that is, when the splicing and assembly is not performed, air will not be output from the self-closing pin, thereby ensuring the effect of starting the connecting pin.

[0034] The expansion board 2 is provided with a pressure relief valve connected to the air circuit 23; the pressure relief valve can prevent excessive pressure in the air circuit 23 to protect the air pump. At the same time, the pressure relief valve can be opened manually, such as by pressing, lifting, etc., and the pressure relief valve that can be opened manually is a common prior art in this field. Therefore, the structure will not be described in detail to facilitate quick operation when disassembling multiple expansion boards 2.

[0035] A battery is arranged in the box body 1, and an operation panel 8 is arranged on the upper side of the box body 1, and a washing basin 81 is embedded in the operation panel 8; the battery can provide electricity during outdoor activities, and of course the battery can also be replaced by a small gasoline generator, which uses gasoline to generate electricity. The operation panel 8 can provide an operating table for the outdoor meal preparation stage, and the washing basin 81 is used for temporarily storing and washing food. Furthermore, an electric water pump can be arranged on the operation panel 8, which can be conveniently used for hydraulic pumping in conjunction with a serpentine water pipe. Example 2: Figure 2 , 5 -7 is a further improvement on Example 1, in which a supporting foot is further provided at the lower end of the expansion plate 2, and the supporting foot is hinged to the expansion plate 2 through a connecting body, and the supporting foot includes a fixed section 5 and a telescopic section, the fixed section 5 is hollow, and the telescopic section includes a fourth limiting piece 51 and a support rod 52 that are connected to each other, the fourth limiting piece 51 is slidingly sealed in the fixed section 5, the support rod 52 is connected to the fourth limiting piece 51 and slides out of the fixed section 5 away from one end of the connecting body, a plurality of limiting holes 53 are opened on the side of the telescopic section, and the telescopic section is sleeved with a fourth spring 54 located in the fixed section 5.

[0036] The connecting body includes a fixed block 6, a rotating block 61 and a hollow rod 62. The fixed block 6 is fixedly connected to the lower end of the expansion plate 2. The fixed block 6 is provided with an inner cavity 63 connected to the air path 23. The rotating block 61 is provided with a rotating seal in the inner cavity 63. The hollow rod 62 is integrally formed with the fixed section 5 and the rotating block 61 and is connected to the fixed block 6 for damping rotation. The rotating block 61 is provided with an L-shaped air groove 64. The hollow portion of the fixed section 5 is connected to the air path 23 through the hollow rod 62 and the L-shaped air groove 64. When the axis of the supporting foot is parallel to the ground, the opening of the L-shaped air groove 64 is cut off from the air path 23. When the axis of the supporting foot is perpendicular to the ground, the opening of the L-shaped air groove 64 is connected to the air path 23.

[0037] Furthermore, when multiple expansion boards 2 are spliced ​​together or heavier items are placed on the expansion boards 2, in order to improve the support stability, the support feet can be flipped during splicing so that their axes are perpendicular to the ground. When the air pump delivers compressed gas to the air path 23 of the expansion board 2, it can be synchronously input through the inner cavity 63 of the fixed block 6. Since the opening of the L-shaped air groove 64 is connected to the air path 23 when the axis of the support foot is perpendicular to the ground, the compressed air will be simultaneously delivered into the hollow part of the fixed section 5 and push the telescopic section to extend outward. At this time, the lower end surface of the telescopic section will gradually approach until it abuts against the ground to form a support. This can improve the support flexibility of the support feet, and there is no need to manually stretch the support feet and the ground support. Compared with the fixed-length support feet, it has the advantage of a higher ability to adapt to the flatness of the ground. At the same time, the pressure relief pressure of the pressure relief valve is set to avoid the situation where the items above the expansion board 2 are too heavy and automatically sink and leak gas. On the contrary, when multiple expansion boards 2 are combined and some of the expansion boards 2 need to ensure that the space below is empty, the axis of the support foot is parallel to the ground to form a storage space. At this time, the opening of the L-shaped air groove 64 is cut off from the air path 23, so that the telescopic section will not be automatically extended by the input of compressed gas, thereby ensuring the stability of the support foot.

[0038] Example 3: Figure 1-3 As shown in Figure 9, based on the further improvement of Example 1, the expansion board 2 is further provided with an auxiliary heater, which includes a rotating drum 7. The rotating drum 7 is rotatably sealed and embedded in the expansion board 2. The axis of the rotating drum 7 is hollow and its position corresponds to the air path 23. A number of one-way exhaust valves 71 are opened on the side of the rotating drum 7. The exhaust pressure of the one-way exhaust valve 71 is greater than the sum of the maximum expansion and contraction pressures of all the first springs 32, the second springs 34, and the third springs 42 on the expansion board 2. The output end of the air pump is connected to an air heater.

[0039] Furthermore, since the ambient temperature in some outdoor areas is too low or in order to meet the needs of heating and keeping food warm, the drum 7 on the expansion plate 2 can be rotated so that the one-way exhaust valve 71 on the drum 7 faces the upper or lower end of the expansion plate 2, and the air heater is turned on to heat the air output by the air pump. At this time, the heated air will be input into the air path 23 of the expansion plate 2 and then output through the one-way exhaust valve 71 of the drum 7. The warm air output in this way can be used for outdoor warm air heating or for placing food on the upper end surface of the expansion plate 2, and then forming a hot air space with a shielding cover to keep the food warm. When the auxiliary heater is not needed, the air heater can be turned off, and then the drum 7 is rotated so that the exhaust port of the one-way exhaust valve 71 faces the expansion plate 2, thereby achieving the effect of closing the air path 23.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
