[0038] Embodiment 1

[0039] As shown in Figures 1-3 The present application discloses a liquid crystal display screen transfer trolley, which comprises a trolley plate 10, a walking wheel 11 installed on the trolley plate 10, a loading and transporting frame installed on the trolley plate 10, and a bearing structure composed of a supporting structure and a plurality of sliding bearing structures installed on the supporting structure.

[0040] The bearing structure has a bearing cavity for placing the liquid crystal display screen, and a moving structure capable of reducing or expanding the bearing cavity is slidingly arranged on the bearing structure.

[0041] In the embodiment, the supporting structure comprises:

[0042] A stand 20 is fixedly connected to the trolley plate 10 at intervals;

[0043] A cross bar 21 is connected between adjacent stands 20.​​

[0044] A sliding groove 22 is formed on the horizontal rod 21 and extends along the horizontal rod 21.

[0045] In the embodiment, the bearing structure comprises:

[0046] The storage frame is composed of a bottom plate 30 and limiting rods 31 installed on the bottom plate 30, and the bearing cavity is formed between each limiting rod 31 and the bottom plate 30.

[0047] A sliding block 32 is fixedly arranged on the bottom plate 30 and can move in the sliding groove 22.

[0048] The moving structure comprises:

[0049] A sliding cavity 40 is formed in the limiting rod 31.

[0050] A sliding shaft 41 is slidingly connected in the sliding cavity 40 and has one end extending out of the sliding cavity 40 and connected with a moving plate 42.

[0051] The moving plate 42 has a support plate 43 slidingly connected with the bottom plate 30, the bottom plate 30 is provided with a movable cavity 30a for the movement of the support plate 43, and the limiting rod 31 is provided with a limiting structure.

[0052] In the embodiment, the limiting structure is a spring 50 arranged in the sliding cavity and connected between the sliding shaft 41 and the sliding cavity 40.

[0053] Reference Figures 1-3 In the embodiment, the liquid crystal display screen can be placed in the bearing cavity and transported by the transfer trolley.

[0054] In order to realize the transfer of products of different sizes, the size of the bearing cavity can be controlled by moving the sliding shaft, and the spring can drive the moving plate to fix the product, so as to avoid the product from separating from the bearing cavity and ensure the stability of the transfer.

[0055] It is worth mentioning that, in order to facilitate loading and unloading, the bottom plate of the embodiment can move on the horizontal rod, so as to facilitate moving the bottom plate out for loading and unloading.

[0056] Embodiment 2 is different from embodiment 1 in that:

[0057] As shown in Figures 4-5 In the embodiment, the limiting structure comprises:

[0058] A limiting groove 51 is formed on the limiting rod 31 and communicates with the sliding cavity 40.

[0059] A limiting shaft 52 is slidingly arranged in the limiting groove 51 and has one end located in the sliding cavity and capable of abutting against the sliding shaft 41.

[0060] The limiting spring 53 is coaxially sleeved on the limiting shaft 52 and is connected between the limiting shaft 52 and the limiting rod 31 and drives the limiting shaft 52 to abut against the sliding shaft 41.

[0061] The limiting rod 31 is provided with a lever structure, which can control the separation of the limiting shaft 52 and the sliding shaft 41.

[0062] In this embodiment, the lever structure comprises:

[0063] The first hinged seat 61 is installed on the limiting rod 31.

[0064] The lever shaft 62 is hinged to the first hinged seat 61.

[0065] The top of the limiting shaft 52 is provided with the second hinged seat 63, and one end of the lever shaft 62 is hinged to the second hinged seat 63 through the pivot 64.

[0066] In this embodiment, the support plate 43 is provided with a support groove 70, the support block 71 is slidably connected in the support groove 70, the groove bottom of the support groove 70 is provided with a threaded hole 72 penetratingly arranged, and the support bolt 73 is installed in the threaded hole 72.

[0067] Reference Figures 4-5 The limiting structure in this embodiment has the advantage that the product is not clamped too tightly, so that the product is not deformed, and the purpose of protecting the product is achieved. In the embodiment 1, the spring is used to limit the sliding shaft, so that the moving plate clamps the product, and there is a possibility that the product is deformed. In this embodiment, the limiting shaft is used to limit the sliding shaft, so that the moving plate clamps the product.

[0068] In more detail, in use, the lever shaft is pressed to drive the limiting shaft and the sliding shaft to separate, so that the sliding shaft can slide. When moved to the appropriate position, the lever shaft is released, and the limiting spring drives the limiting shaft and the sliding shaft to abut, so as to fix the sliding shaft.

[0069] Furthermore, in order to avoid product deformation, the support block is arranged on the support plate. Since the support surface of the support plate and the bottom plate is not in the same plane, when the product is placed, the positions of both ends are not supported, so it is easy to deform. In use, the support bolt can control the support block to rise and be in the same plane with the bottom plate, so as to support the product in all directions, thereby avoiding product deformation.

[0070] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
