When a plurality of the frames 100 are stacked and placed, they have strong stability, which can effectively prevent the upper-layer frame 100 from tipping over and improve the transfer efficiency of the leaf spring steel plates.

[0027] As a preferred embodiment, please refer to Figure 4 and Figure 5 , a plurality of card slots 120 are spaced apart on the lower surface of the frame 100, and each of the connecting portions is respectively arranged in the corresponding card slot 120, and the connecting portion can be received through the card slot 120.

[0028] As a preferred embodiment, please refer to Figure 4 and Figure 5 , the leaf spring steel plate transfer rack further includes a plurality of blocks 300. Each of the blocks 300 is fixedly arranged at intervals on the upper surface of the frame 100 and corresponds to each of the card slots 120 one by one. When the upper-layer frame 100 is placed on the lower-layer frame 100, each of the card slots 120 of the upper-layer frame 100 is respectively sleeved on each of the blocks 300 of the lower-layer frame 100 to realize the clamping connection between the upper-layer frame 100 and the lower-layer frame 100.

[0031] As a preferred embodiment, please refer to Figure 4 and Figure 5 The locking mechanism 200 includes a mounting member 210, a connecting member 220, and a first driving member 230. The mounting member 210 is a rod with an L-shaped structure, and the mounting member 210 is fixedly arranged in the receiving groove 310 to form the mounting portion. The connecting member 220 is a rod with an L-shaped structure, and the connecting member 220 is arranged in the clamping groove 120 to form the connecting portion. The upper end of the vertical rod of the connecting member 220 is rotatably connected to the frame 100. The upper surface of the horizontal rod of the connecting member 220 is used to abut against the lower surface of the horizontal rod of the mounting member 210. One end of the first driving member 230 is fixedly connected to the vertical rod of the connecting member 220, and the other end of the first driving member 230 rotatably extends out of the clamping groove 120. When the upper frame 100 is placed on the lower frame 100, the horizontal rod of the connecting member 220 will cross over the horizontal rod of the mounting member 210, and the vertical rod of the connecting member 220 will return to the vertical state under its own gravity, so that the upper surface of the horizontal rod of the connecting member 220 abuts against the lower surface of the horizontal rod of the mounting member 210, thereby realizing the clamping connection between the connecting member 220 and the mounting member 210, and making the upper frame 100 and the lower frame 100 detachably fixed. When it is necessary to remove the upper frame 100, manually rotate the other end of the first driving member 230, so that the vertical rod of the connecting member 220 rotates away from the mounting member 210 until the upper surface of the horizontal rod of the connecting member 220 is separated from the lower surface of the horizontal rod of the mounting member 210, thereby disconnecting the upper frame 100 from the lower frame 100.

When the through hole 231 is aligned with the corresponding positioning hole 130, the upper surface of the cross bar of the connecting member 220 is separated from the lower surface of the cross bar of the mounting member 210. Inserting the positioning member into the through hole 231 and the positioning hole 130 can lock the position of the first driving member 230, and further lock the position of the cross bar of the connecting member 220.

[0035] As a preferred embodiment, please refer to Figure 4 and Figure 5 , the first driving member 230 is a driving rod, and the driving rod is parallel to the vertical rod of the connecting member 220.

[0036] As a preferred embodiment, please refer to Figure 4 and Figure 5 , the locking mechanism 200 further includes an elastic member 250. The elastic member 250 is arranged in the clamping groove 120.

The elastic member 250 is a spring.

[0037] As a preferred embodiment, please refer to Figure 1 and Figure 2, the leaf spring steel plate transfer rack further includes a plurality of clamping mechanisms 400.

Each second driving member 420 is connected to each clamping rod 410 in a one-to-one correspondence and is used to drive each clamping rod 410 to abut against or separate from the leaf spring steel plate, so as to position the leaf spring steel plate and prevent the leaf spring steel plate from moving in the cavity 110.

[0038] As a preferred embodiment, please refer to Figure 1 and Figure 2 , the second driving member 420 is a screw rod. A plurality of screw holes are formed in the frame 100. Each screw rod is screwed into each screw hole in a one-to-one correspondence. By rotating the screw rod, since the clamping rod 410 is slidably connected to the frame 100, during the process of rotating the screw rod, the screw rod can be driven to abut against or separate from the leaf spring steel plate.

[0039] To better understand the present invention, the working principle of the technical solution of the present invention will be described in detail below in conjunction with Figure 1 - Figure 5 :

[0040] In use, each leaf spring steel plate is respectively placed in the cavity 110 of each of the frames 100, and a plurality of the frames 100 are stacked and placed on a trolley. When the upper frame 100 is placed on the lower frame 100, each of the clamping grooves 120 of the upper frame 100 is respectively sleeved on each of the clamping blocks 300 of the lower frame 100, so as to realize the clamping connection between the upper frame 100 and the lower frame 100. Moreover, the cross bar of the connecting piece 220 will cross over the cross bar of the mounting piece 210, and the vertical bar of the connecting piece 220 returns to the vertical state again under its own gravity and the action of the elastic member 250, so that the upper surface of the cross bar of the connecting piece 220 abuts against the lower surface of the cross bar of the mounting piece 210, thereby realizing the clamping connection between the connecting piece 220 and the mounting piece 210, and enabling the upper frame 100 and the lower frame 100 to be detachably fixed. When it is necessary to remove the upper frame 100, manually rotate the first driving member 230 to align the through hole 231 on the first driving member 230 with the corresponding positioning hole 130. After the through hole 231 on the first driving member 230 is aligned with the corresponding positioning hole 130, the upper surface of the cross bar of the connecting piece 220 is separated from the lower surface of the cross bar of the mounting piece 210. Insert the positioning member into the through hole 231 and the positioning hole 130, and the position of the first driving member 230 can be locked, and further the position of the cross bar of the connecting piece 220 can be locked, so that the connection between the upper frame 100 and the lower frame 100 can be released, and the upper frame 100 can be removed. In the present utility model, when the frames 100 are stacked and placed, the upper frame 100 and the lower frame 100 can be fixedly connected, so that when a plurality of the frames 100 are stacked and placed, they have strong stability, can effectively prevent the upper frame 100 from tipping over, and improve the transfer efficiency of the leaf spring steel plates.

[0041] The leaf spring steel plate transfer rack provided by the present utility model has the following beneficial effects:

[0042] (1)When the upper frame 100 is placed on the lower frame 100, each of the card slots 120 of the upper frame 100 is respectively sleeved on each of the card blocks 300 of the lower frame 100, realizing the snap connection between the upper frame 100 and the lower frame 100. Moreover, the cross bar of the connecting piece 220 will cross over the cross bar of the mounting piece 210, and the vertical bar of the connecting piece 220 returns to the vertical state again under its own gravity and the action of the elastic member 250, so that the upper surface of the cross bar of the connecting piece 220 abuts against the lower surface of the cross bar of the mounting piece 210, thereby realizing the snap connection between the connecting piece 220 and the mounting piece 210, enabling the detachable fixation between the upper frame 100 and the lower frame 100. The connection strength between the upper frame 100 and the lower frame 100 is high, and the disassembly and assembly are convenient;

[0043] (2)Through each of the clamping rods 410, the leaf spring steel plate can be positioned to prevent the leaf spring steel plate from moving in the cavity 110;

[0044] (3)When the frames 100 are stacked, the upper frame 100 and the lower frame 100 can be fixedly connected, so that when multiple frames 100 are stacked, they have strong stability, which can effectively prevent the upper frame 100 from tipping over and improve the transfer efficiency of the leaf spring steel plate.
