[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-5 A folding material rack for an aviation food processing workshop includes a back frame 10, with side frames 20 on both sides of the back frame 10. The side frames 20 are rotatably connected to the back frame 10, and a locking assembly 50 is connected to the side frames 20 and the back frame 10 to restrain the side frames 20 from rotating relative to the back frame 10. Each side frame 20 has at least one insertion track 210, and a shelf 30 is disposed between the two insertion tracks 210. The left and right sides of the shelf 30 are respectively inserted into the two insertion tracks 210. The insertion tracks 210 are provided with limiting structures to restrain the forward and backward movement of the shelf 30. In this embodiment, the limiting structure restrains the forward and backward movement of the inserted shelf, and the shelf can be quickly disassembled after the limiting is released. Simultaneously, the rotatable side frame can be flipped to a state parallel to the back frame after the locking assembly is released for easy storage.

[0025] An operating port 310 is provided on the front side of the shelf 30. The operating port 310 is designed to be easy to hold, so as to move the shelf 30 back and forth.

[0026] See Figure 2 Limiting pins 300 are provided on the left and right side walls of the shelf 30, and limiting grooves 220 are provided on the insertion track 210 corresponding to the positions of the limiting pins 300. The side frame 20 can rotate clockwise or counterclockwise relative to the back frame 10, allowing the limiting pins 300 to insert into or disengage from the limiting grooves 220. In this embodiment, the insertion and engagement of the limiting pins 300 and the limiting grooves 220 constrains the shelf 30 to disengage forward from the insertion track 210, thus locking the shelf 30. When it is necessary to disassemble the shelf 30, the side frame 20 is flipped, and during this process, the limiting pins 300 disengage from the limiting grooves 220. This unlocking process completes the process, allowing the unlocked shelf 30 to move relative to the insertion track 210.

[0027] See Figure 5 The back frame 10 is fixedly connected to the left and right sides with first connecting seats 410, each with a shaft hole 420. The side frame 20 is provided with a second connecting seat 430, each with a rotating shaft 440 that is movably inserted into the shaft hole 420. When the side frame 20 rotates relative to the back frame 10, it rotates around the rotating shaft 440 as its axis.

[0028] See Figure 5The rotating shaft 440 is provided with an annular limiting groove 450, and the first connecting seat 410 is connected to a limiting post 460 that is movably inserted into the annular limiting groove 450.

[0029] Furthermore, the first connecting seat 410 is provided with a threaded hole, and the limiting post 460 is threadedly connected to the threaded hole.

[0030] The function of the limiting post 460 is to constrain the vertical position of the rotating shaft 440 and prevent it from disengaging from the shaft hole 420.

[0031] See Figure 5 The locking assembly 50 includes a locking hole 470 on the first connecting seat 410. The second connecting seat 430 has a movable member 520 that is vertically movable relative to the second connecting seat 430. The movable member 520 is connected to a locking pin 530 that can be movably inserted into the locking hole 470. When the locking pin 530 is inserted into the locking hole 470, it is in a locked state, and the side frame 20 cannot rotate relative to the back frame 10. When rotation is required, the movable member 520 needs to be driven upward to disengage the locking pin 530 from the locking hole 470, thereby unlocking the side frame 20 and allowing it to rotate relative to the back frame 10.

[0032] See Figure 5 The movable member 520 is connected to the second connecting seat 430 by an elastic element 560. The elastic element 560 applies a force to the movable member 520 so that the locking pin 530 remains inserted in the locking hole 470.

[0033] Furthermore, the elastic element 560 is a spring.

[0034] See Figure 5 The movable component 520 is connected to an unlocking lever 550. The function of the unlocking lever 550 is to facilitate gripping so as to move the movable component 520 upward.

[0035] See Figure 5 The second connecting seat 430 is provided with a movable groove 510, the movable groove 510 is connected to an operating hole 540 with an upper opening, the movable member 520 is moved up and down in the movable groove 510, and the unlocking operating rod 550 is movably inserted into the operating hole 540.

[0036] See Figure 5 The rear end of the shelf 30 is provided with a positioning post 320, and the back frame 10 is provided with a positioning hole 100. The positioning post 320 is movably inserted into the positioning hole 100. The insertion and cooperation of the two can effectively enhance the stability of the shelf.
