[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The present application embodiment discloses a baking lasagna rack. Figure 1 The lasagna baking rack includes a frame 1, a plurality of support members 2, a plurality of pressing members 3 and a plurality of fixing members 4. The support members 2 are rotatably connected to the frame 1. The plurality of support members 2 are arranged in parallel and spaced apart along the length direction of the frame 1, so that when the previous support member 2 is rotated and turned up, the next support member 2 can be used to place or fold the circuit board.

[0036] One support member 2 corresponds to at least two pressing members 3 and at least two fixing members 4. The pressing members 3 in this embodiment are made of metal and are used to press the circuit board. The fixing members 4 are used to fix the support member 2 so that the circuit board can be stably placed on the support member 2. The pressing members 3 are arranged at intervals on the side of the support member 2 away from the frame 1. In this embodiment, the pressing members 3 are arranged on both sides of the side of the support member 2 away from the frame 1, close to the corners. The pressing members 3 of the upper layer of support members 2 press against the lower layer of support members 2. When the circuit board is placed on the support member 2, the upper layer of support members 2 is rotated and the pressing members 3 are pressed against the corners of the circuit board so that the circuit board is pressed and fixed. The fixing member 4 is used to fix two adjacent support members 2. By fixing the two adjacent support members 2 through the fixing member 4, when the Thousand Layer Frame vibrates during the transfer process, the shaking between the support members 2 can be better avoided as much as possible, and the circuit board can still be stably placed on the support member 2.

[0037] Reference Figure 2 In some embodiments, the support member 2 includes a plurality of support cross bars 21 and a plurality of support vertical bars 22, and the support cross bars 21 and the support vertical bars 22 are arranged perpendicularly and crosswise to form the support member 2, that is, the support member 2 is a grid structure. In this embodiment, the support cross bars 21 and the support vertical bars 22 are fixed by welding, so that during the baking process of the circuit board, better air flow can be achieved, making the baking more comprehensive, so as to better improve the baking efficiency.

[0038] In some embodiments, the fixing member 4 of this embodiment is arranged in an "L"-shaped structure, and one side of the fixing member 4 is fixedly connected to the bottom of the support member 2, so that the fixing member 4 can be conveniently used to fix the two adjacent support members 2. When the fixing member 4 is made of metal material, it can be fixed to the support member 2 by welding. The fixing member 4 can also be made of high-temperature resistant plastic material, in which case it can be fixed to the support member 2 by fixing methods such as high-temperature resistant glue and screw connection. The side of the fixing member 4 facing away from the upper support member 2 is detachably connected to the lower support member 2, so that the separation and fixation between the two adjacent support members 2 can be achieved by only flipping up the upper support member 2 or putting down the upper support member 2.

[0039] In some embodiments, the two ends of the fixing member 4 are respectively provided with a snap-in groove 5. When fixed, one end of the fixing member 4 is snap-into the support vertical rod 22, and the other end of the fixing member 4 is snap-into the support cross bar 21. This means that the support vertical rod 22 and the support cross bar 21 are snapped into the snap-in groove 5, and the wall surfaces of the fixing member 4 corresponding to the snap-in groove 5 are snap-into each other. This makes it convenient to temporarily fix the upper support member 2 and the lower support member 2, and when it is necessary to rotate and open the upper support member 2, the upper support member 2 can be conveniently rotated upward to open it. After the fixing member 4 is snap-into the support vertical rod 22 and the support cross bar 21, there is friction, and the shaking and vibration generated during the transportation of the circuit board will not cause the fixing member 4 to separate from the support member 2.

[0040] In some embodiments, when two adjacent support members 2 are fixed, a distance is left between the end surface of the fixing member 4 facing the lower support member 2 and the support member 2. The support member 2 is in a grid shape and has the ability to deform elastically, and the distance can leave enough space for the circuit board, so that the circuit board can be limited and fixed, and the circuit board can also be better protected.

[0041] In some embodiments, a pad (not shown) is provided on the end surface of the fixing member 4 facing the lower support member 2. The pad in this embodiment is made of high temperature resistant rubber, or other high temperature resistant elastic or flexible materials. When the support members 2 in this embodiment abut against each other, the pad fits the surface of the circuit board exactly, and does not squeeze the circuit board. That is, the circuit board can be limited and fixed at the same time, and the circuit board can also be better protected.

[0042] Reference Figure 3 and Figure 4 In some embodiments, the lasagna baking rack further includes a tension spring 6. One support member 2 corresponds to two tension springs 6. The tension springs 6 are respectively arranged on both sides of the support member 2, so that when the support member 2 is turned up, the tension spring 6 can support the support member 2, so that the next support member 2 can be placed or the circuit board can be stored more conveniently. One end of the tension spring 6 is connected to the support member 2. In this embodiment, one end of the tension spring 6 is hooked on the support member 2, and the other end is connected to the frame 1.

[0043] In some embodiments, the lasagna baking rack further includes an adjusting member 7, which is used to adjust the tension of the tension spring 6. The adjusting member 7 is arranged in a one-to-one correspondence with the tension spring 6, and the adjusting member 7 is connected to one end of the tension spring 6 away from the support member 2. The adjusting member 7 is adjustable between the adjusting member 7 and the rack body 1. This allows the tension of the tension spring 6 to be adjusted, so that the support member 2 can be flipped up and fixed better.

[0044] In some embodiments, the adjusting member 7 includes an adjusting bolt 71 and an adjusting nut 72, one end of the adjusting bolt 71 is connected to the tension spring 6, one end of the tension spring 6 in this embodiment is hooked on the adjusting bolt 71, and the other end is passed through the frame 1, and the adjusting nut 72 is screwed on the adjusting bolt 71 and abuts against the side of the frame 1 away from the tension spring 6. The end of the tension spring 6 away from the support member 2 is fixed, and the tension of the tension spring 6 is changed by screwing the adjusting nut 72 into the adjusting bolt 71, and the adjusting nut 72 can be fine-tuned, so the support member 2 can be better adjusted.

[0045] The implementation principle of a baking lasagna rack in an embodiment of the present application is as follows: a circuit board is placed on the support member 2, and when the support member 2 of the upper layer is rotated to abut against the support member 2 of the lower layer, the pressing member 3 presses and fixes the circuit board, and the support members 2 of two adjacent layers are fixed by the fixing member 4, so that during the transportation of the lasagna rack, the shaking and swaying of the support member 2 is reduced, so that the pressing member 3 can still stably press against the circuit board, so that the circuit board can be stably placed.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
