Specific embodiments

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Embodiment 1: As Figure 1-10 shown, a cooking integrated mobile platform includes a main box, the main box includes a cabinet 1 and a lid 11 that are hinged to each other, and a cooking range 12 is provided inside the lid 11. It is characterized in that: expansion mechanisms are provided on both sides of the cabinet 1 that are not covered after the lid 11 is flipped;

[0032] The expansion mechanism includes an expansion board 2, fastening strips 21, connecting strips 22 and a locking assembly. The number of fastening strips 21 and connecting strips 22 is several and they are oppositely arranged on the four side parts of the expansion board 2. One of the fastening strips 21 is provided on the side of the cabinet 1, and the locking assembly is provided on the expansion board 2;

[0033] The locking assembly includes a connecting pin and a self-closing pin. The self-closing pin is provided in the middle of the fastening strip 21, the connecting pin is provided on the connecting strip 22, an air pump is provided in the cabinet 1, and the output end of the air pump is connected to the self-closing pin gas path 23 in the fastening strip 21 provided on the cabinet 1 through a conduit. An air path 23 is opened in the expansion board 2, 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 board 2, and a one-way intake valve 25 and a sealing ring 26 are provided in the bypass 24. The sealing ring 26 is closer to the opening of the bypass 24 than the one-way intake valve 25.

[0034] When using this device outdoors, in its initial state, 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 handle at the side, the device can be conveniently towed and carried until it reaches the designated position. At this time, according to the number of people participating in the outdoor activity and the size of the venue, the operating table can be freely assembled through the expansion mechanism. Among them, the stove 12 is used to cooperate with the container when using a portable gas stove outdoors to keep it stably suspended. And the induction cooker 13 can be elevated and supported stably by the bracket in the box cover 11 with the additional equipped generator, so as to meet the need of cooking with the induction cooker 13. Among them, the induction cooker 13 is a common DC induction cooker outdoors;

[0035] When assembling, align the connecting strip 22 of the expansion board 2 with the side of the buckling strip 21 and slide it in. Of course, the buckling strips 21 and connecting strips 22 of two expansion boards 2 can also be connected to each other. In this way, the assembly between the box body 1 and the expansion board 2 or multiple expansion boards 2 can be completed. Among them, because the buckling strip 21 and the connecting strip 22 are arranged on the expansion board 2 in a relatively side-by-side manner, multiple expansion boards 2 can be flexibly combined according to actual needs to form various splicing table structures such as long rectangles, squares, L-shapes, etc.;

[0036] Furthermore, after multiple expansion boards 2 are spliced and assembled, start the air pump in the box body 1 to output compressed air. At this time, the compressed air is input into the self-locking pin on the box body 1 through the conduit. The self-locking pin is then activated by the pneumatic pressure and inputs the air into the air path 23 of the connected expansion board 2 to drive the locking pins in the expansion board 2 to form a lock. At the same time, multiple expansion boards 2 can be locked simultaneously, which can quickly complete the splicing and fixing and more conveniently and quickly complete the splicing combination.

[0037] The buckling strip 21 has a spherical cover structure with an opening, and the connecting strip 22 has 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 buckling strip 21.

[0038] The structures of the buckling strip 21 and the connecting strip 22 not only facilitate connection but also increase the force-bearing area, making it more stable when supporting heavy objects placed on the expansion board 2.

[0039] The self-locking pin includes an insertion rod 3, a first limiting piece 31, a first spring 32, a sliding cover 33, a second spring 34 and a second limiting piece 35. A first stepped cavity 36 communicating with the spherical cover structure is formed in the buckling strip 21. The first limiting piece 31 is slidably and sealingly arranged in the first stepped cavity 36. The insertion rod 3 is concentrically connected to the first limiting piece 31. The second limiting piece 35 is arranged in the middle of the insertion rod 3. The sliding cover 33 is slidably and sealingly connected to one end of the insertion rod 3 away from the first limiting piece 31 through a chute. The second spring 34 is sleeved on the insertion rod 3 and is located between the sliding cover 33 and the second limiting piece 35. A snap ring 37 is arranged 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 piece 31 and the snap ring 37. An air supply channel 38 is formed at the axis of the insertion rod 3. One end opening of the air supply channel 38 is communicated with an air pump, and the other end opening of the air supply channel 38 is located at the side of the insertion rod 3 and corresponds to the sliding cover 33. The inner ring diameter of the sealing sleeve 26 matches the insertion rod 3.

[0040] The connecting pin includes a third limiting piece 4, a limiting rod 41 and a third spring 42. A second stepped cavity 43 communicating with the air path 23 is formed jointly between the expansion plate 2 and the connecting strip 22. The third limiting piece 4 is slidably and sealingly arranged in the second stepped cavity 43. The limiting rod 41 is concentrically connected to the third limiting piece 4. The third spring 42 is sleeved on the limiting rod 41 and is located in the second stepped cavity 43. The buckling strip 21 is provided with a jack 44 matching the limiting rod 41.

[0041] When the air pump outputs compressed air into the self-locking pin, since the opening of the air supply channel 38 of the insertion rod 3 is blocked by the sliding cover 33 in the initial state, the air pressure will directly push the insertion rod 3 to move in the first stepped cavity 36 towards the bypass 24 of the corresponding connecting strip 22. At this time, the second spring 34 sleeved on the insertion rod 3 is blocked by the second limiting piece 35 and the sealing sleeve 26 in the bypass 24, and will slide along the axial direction of the insertion rod 3 in the opposite direction of the moving direction. At this time, the insertion rod 3 will extend into the sealing sleeve 26. The inner ring wall of the sealing sleeve 26 is provided with a sealing rubber ring. Until the opening of the air supply channel 38 on the insertion rod 3 extends between the sealing sleeve 26 and the one-way intake valve 25, the compressed air will be input into the air path 23 of the expansion plate 2 through the air supply channel 38, and then drive the limiting rod 41 in the connecting pin to slide and extend into the jack 44 of the corresponding buckling strip 21 through the compressed air to complete the displacement limit;

[0042] When the compressed air delivery of the air pump stops, the insertion rod 3 of the self-locking pin is reset by the first spring 32, and the sliding cover 33 is reset by the second spring 34 to be completely received into the first stepped cavity 36. In this way, on the one hand, it is convenient for the sliding assembly between the buckling strip 21 and the connecting strip 22 in the early stage to avoid component blockage. On the other hand, a more closed air path 23 can be formed when delivering air, reducing gas leakage to improve the connection efficiency;

[0043] Furthermore, since the air supply channel 38 on the self-closing pin must be exposed by abutting against the sealing collar 26 on the connecting strip 22, when the fastening strip 21 of the expansion plate 2 is not connected to the connecting strip 22, that is, when the splicing and assembly are not carried out, air will not be output from the self-closing pin, which can ensure the effect of starting the connecting pin.

[0044] The expansion plate 2 is provided with a pressure relief valve communicated with the air path 23; setting the pressure relief valve can avoid excessive pressure in the air path 23 to protect the air pump. At the same time, the pressure relief valve can be manually opened, such as by pressing or lifting, etc. And the pressure relief valve that can be manually opened is a common prior art in this field, so the structure will not be described in too much detail to facilitate quick operation when disassembling multiple expansion plates 2.

[0045] A storage battery is provided in the box body 1, and an operation panel 8 is clamped on the upper side in the box body 1. The operation panel 8 is embedded with a washing basin 81; the storage battery can provide power during outdoor activities. Of course, the storage battery can also be replaced with a small gasoline generator for power generation using gasoline. The operation panel 8 can provide an operation tabletop during the outdoor meal preparation stage. The washing basin 81 is used to temporarily store and wash food. Further, an electric water pump can also be provided on the operation panel 8, which can cooperate with the snake-shaped water pipe to facilitate hydraulic pumping.

[0046] Embodiment 2: As Figure 2 、 5 shown in -7, which is a further improvement based on Embodiment 1. A support foot is further provided at the lower end of the expansion plate 2. The support foot is hinged to the expansion plate 2 through a connecting body. The support foot includes a fixed section 5 and a telescopic section. The fixed section 5 is hollow. The telescopic section includes a fourth limiting piece 51 and a support rod 52 connected to each other. The fourth limiting piece 51 is slidably sealed in the fixed section 5. The support rod 52 is connected to the fourth limiting piece 51 and slidably extends out of one end of the fixed section 5 away from the connecting body. A plurality of limiting holes 53 are opened on the side of the telescopic section. A fourth spring 54 located in the fixed section 5 is sleeved on the telescopic section.

[0047] 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 communicated with the air path 23. The rotating block 61 is rotatably sealed in the inner cavity 63. The hollow rod 62 is integrally formed with the fixed section 5 and the rotating block 61 and is rotatably connected to the fixed block 6 with damping. The rotating block 61 is provided with an L-shaped air groove 64. The hollow part of the fixed section 5 is communicated with the air path 23 through the hollow rod 62 and the L-shaped air groove 64. When the axis of the support 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 support foot is perpendicular to the ground, the opening of the L-shaped air groove 64 is communicated with the air path 23.

[0048] Further, when multiple extension boards 2 are spliced and combined or heavy objects are placed on the extension board 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 conveys compressed gas into the air path 23 of the extension 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 communicates with the air path 23 when the axis of the support foot is perpendicular to the ground, at this time, compressed air will be simultaneously conveyed into the hollow part of the fixed section 5 and push the telescopic section to extend outwards. At this time, the lower end surface of the telescopic section will gradually approach and abut against the ground to form a support. This can improve the support flexibility of the support feet, eliminating the need for manual stretching of the support feet to support the ground. Compared with support feet of fixed length, it has the advantage of higher adaptability to the ground flatness. At the same time, by setting the pressure relief degree of the pressure relief valve, it can prevent the situation where the gas leaks out automatically due to the overweight of the objects above the extension board 2;

[0049] Conversely, when multiple extension boards 2 are combined and some extension boards 2 need to ensure that the space below is blank, the axes of the support feet are parallel to the ground to form a storage state. 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 automatically extend due to the input of compressed gas, ensuring the stable state of the support feet.

[0050] Embodiment 3: As shown in Figure 1-3 Figures 8 and 9, which is a further improvement based on Embodiment 1. The extension board 2 is also provided with an auxiliary heater. The auxiliary heater includes a rotating cylinder 7. The rotating cylinder 7 is rotationally and sealingly embedded in the extension board 2. The axis of the rotating cylinder 7 is hollow and corresponds to the air path 23 in position. A number of one-way exhaust valves 71 are opened on the side of the rotating cylinder 7. The exhaust pressure of the one-way exhaust valves 71 is greater than the sum of the maximum expansion pressures of all the first springs 32, second springs 34, and third springs 42 on the extension board 2. The output end of the air pump is connected to an air heater.

[0051] Further, since the environmental temperature in some outdoor areas is too low or to meet the needs of heating and keeping food warm, at this time, the rotating cylinder 7 on the extension board 2 can be rotated so that the one-way exhaust valves 71 on the rotating cylinder 7 face the upper or lower end of the extension board 2. At the same time, 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 extension board 2 and then output through the one-way exhaust valves 71 of the rotating cylinder 7. In this way, the output warm air can be used for outdoor warm air heating or, when food is placed on the upper end surface of the extension board 2, cooperate with the shielding cover to form a hot air space, thereby achieving the effect of keeping the food warm. When the auxiliary heater is not needed, the air heater can be turned off, and then the rotating cylinder 7 is rotated so that the exhaust port of the one-way exhaust valve 71 faces the extension board 2, thereby achieving the effect of closing the air path 23.

[0052] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
