Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides an embodiment: an oven space blocking device for an aircraft kitchen, comprising a bottom frame 1, a top frame 2 is arranged above the bottom frame 1, two lifting structures 3 are installed on one side of the top of the bottom frame 1, and two sliding rods 4 used in conjunction with the lifting structures 3 are installed on the other side of the top of the bottom frame 1. The tops of the lifting structures 3 and the sliding rods 4 are both connected to the bottom end of the top frame 2, and a middle support box 5 is installed between the lifting structure 3 and the sliding rods 4. The lifting structure 3 includes a one-way screw rod 301 rotatably installed on one side of the top of the bottom frame 1, and a nut pair 302 for driving the middle support box 5 to rise and fall is installed at the threaded portion of the surface of the one-way screw rod 301, and the bottom end of the one-way screw rod 301 extends to the interior of the bottom frame 1 and is installed with a conical gear transmission structure 303;

[0018] The staff rotates the conical gear transmission structure 1 303 by rotating the handle, and the conical gear transmission structure 1 303 drives the nut pair 1 302 to move up and down on the surface of the one-way screw 301 through the one-way screw 301, thereby driving the middle support box 5 to move up and down between the lifting structure 3 and the sliding rod 4, which can simultaneously block multiple empty spaces in the oven, thereby improving the flexibility of the blocking device;

[0019] A bidirectional pitch-adjusting structure 6 is installed inside the middle bearing box 5, and a blocking structure 9 is installed at the movable end of the bidirectional pitch-adjusting structure 6. The bidirectional pitch-adjusting structure 6 includes a bidirectional screw rod 601 rotatably installed inside the middle bearing box 5, and a second conical gear transmission structure 603 for driving the bidirectional screw rod 601 to rotate is installed at the center position of the bidirectional screw rod 601, and a second nut pair 602 is installed at the threads at both ends of the surface of the bidirectional screw rod 601, and a blocking structure 9 is installed at the bottom end of the second nut pair 602;

[0020] The staff rotates the second conical gear transmission structure 603 through the handle, and the second conical gear transmission structure 603 drives the second nut pair 602 to move toward or oppositely on the surface of the two-way screw 601 through the two-way screw 601, thereby driving the blocking structure 9 to flexibly block the empty space in the oven, so that the blocking device blocks and fixes the empty space for food in the oven, which can prevent the food being baked from moving or tipping over due to the turbulence and shaking during the flight of the aircraft, causing the food to fail to be baked;

[0021] The blocking structure 9 includes a rectangular hollow box fixed to one side of the bottom end of the middle support box 5, and a rectangular blocking strip slidably installed inside the rectangular hollow box. One side outer wall of the rectangular blocking strip is fixedly connected to one side outer wall of the second nut pair 602. When the second nut pair 602 moves on the surface of the bidirectional screw rod 601, it drives the rectangular blocking strip to move inside the rectangular hollow box. The length of the blocking structure 9 is adjustable, so as to flexibly block the blank position in the baking oven.

[0022] The bottom end of the bottom frame 1 and the top end of the top frame 2 are both installed with a fixing structure 7 for fixing themselves, the fixing structure 7 includes a fixing block 702 installed at two movable ends of the screw moving structure 8, springs 703 are installed on both sides of the outer wall of the fixing block 702, and a support leg 701 is installed at one end of the spring 703 away from the fixing block 702, and one end of the support leg 701 away from the spring 703 is hinged to the center point of the bottom end of the bottom frame 1 or the center point of the top end of the top frame 2;

[0023] The staff adjusts the screw moving structure 8 by rotating the handle, so that the two movable ends of the screw moving structure 8 move relative to or oppositely, thereby driving the two fixed blocks 702 to move closer to or away from each other, thereby pulling the legs 701 at one end of the spring 703 to close together or bounce away from each other, thereby realizing the installation of the blocking device in the oven;

[0024] A screw moving structure 8 for adjusting the fixed structure 7 is installed at the center position of the top of the bottom frame 1 and the center position of the bottom of the top frame 2. The screw moving structure 8 includes a mounting box installed at the center position of the bottom end of the bottom frame 1, and a bidirectional threaded shaft rotatably installed inside the mounting box. Nut pairs are installed at the threads at both ends of the surface of the bidirectional threaded shaft. The top end of the nut pair penetrates the outside of the bottom frame 1 and is fixedly connected to the bottom end of the fixed block 702.

[0025] When the staff rotates the bidirectional threaded shaft in the installation box through the handle, the nut pairs at both ends of the surface of the bidirectional threaded shaft are driven to move relative to or towards each other, thereby driving the two fixed blocks 702 to move relative to or oppositely, and then adjusting the screw moving structure 8 to pull the fixed blocks 702 and the spring 703 to adjust the mutual retraction or mutual bounce of the support legs 701.

[0026] When the embodiment of the present application is in use, the staff first adjusts the screw moving structure 8 on the inner wall of the bottom frame 1 and the top frame 2 to retract the fixed structure 7, and then puts the device into the oven. Then the staff rotates the screw moving structure 8 again to restore the elasticity of the fixed structure 7. The fixed structure 7 presses against the inner wall of the oven due to its elasticity, so that the bottom frame 1 and the top frame 2 can be fixed inside the oven. Then the staff adjusts the lifting structure 3 so that the two two-way distance adjustment structures 6 can be moved to a column with an empty space in the oven. Finally, the staff adjusts the two-way distance adjustment structure 6 to make the two-way distance adjustment structure 6 The distance structure 6 drives the two blocking structures 9 to move relative to each other, and fills the empty spaces on both sides of the food. The setting of the fixing structure 7 makes the blocking device simple to install, easy to take and use, convenient to use, and firmly fixed. The setting of the lifting structure 3 can block multiple empty spaces in the oven at the same time, thereby improving the flexibility of the device. The use of the two-way adjustable distance structure 6 enables the blocking device to enable the oven to be used normally when the aircraft is flying. The blocking device blocks and fixes the empty spaces of food in the oven, and can prevent the food being baked from moving or tipping over due to the shaking of the aircraft during flight, thereby preventing the failure of food baking.
