[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0027] like Figures 1 to 4 As shown, a composite material tray for carrying polarizers for TFT-LCD includes a rectangular bottom plate 1, two first baffles 2, two second baffles 3, and four L-shaped connecting blocks 4. The first baffles 2 and the second baffles 3 are both made of profiles and have the same structural shape. The two ends of the profiles are set at an inclined angle, and the sum of the two is 180 degrees; the first baffles 2 are set on both sides of the bottom plate 1, and the second baffles 3 are set on the other two sides of the bottom plate 1. The adjacent first baffles 2 and second baffles 3 are connected by L-shaped connecting blocks 4, so that the bottom plate 1 and the first baffles 2 and the second baffles 3 form a rectangular trough body that can hold the polarizers for TFT-LCD.

[0028] The profile is provided with a placement groove 201 on one side close to the bottom plate 1, and the placement groove 201 is adapted to the bottom plate 1 so that the bottom plate 1 is embedded in the profile; the profile is provided with a positioning cavity 202 above the placement groove 201, and the positioning cavity 202 is adapted to the end of the L-shaped connecting block 4, so that two adjacent profiles can be quickly assembled through the L-shaped connecting block 4, and because the two ends of the L-shaped connection are respectively embedded in the positioning cavities 202 of the two adjacent profiles, when the assembly is completed, the connecting piece is hidden to increase the appearance of the appearance; the profile is provided with a hand buckle groove 205 on the side away from the honeycomb panel 1, It is convenient for staff to carry; and two threaded holes 206 are provided on the hand buckle groove 205, and the threaded holes 206 are located on the cavity wall of the positioning cavity 202 and correspond to the position of the L-shaped connecting block 4. A locking screw 5 is installed in the threaded hole 206, and the locking screw 5 is connected to the L-shaped connecting block 4, to fix the L-shaped connecting block 4 installed between two adjacent profiles so that it will not move in the positioning cavity, and at the same time, it is easy to disassemble and can be recycled for many times, saving costs. At the same time, the threaded hole 206 is arranged at the hand buckle groove 205 to increase the aesthetics.

[0029] Furthermore, the profile is provided with a reinforcement portion 203 above the positioning cavity 202 to increase strength and prevent bending deformation when multiple layers are stacked; and a convex portion 204 is formed by extending upward on the side of the reinforcement portion 203 away from the bottom plate 1, and the width of the upper surface of the reinforcement portion 203 is greater than the width of the lower surface of the placement groove 201, such as Figure 5 As shown, when two trays are stacked, the bottom of the upper tray contacts the reinforcing portion 203 of the lower tray, ensuring the stability of the trays when they are stacked up and down, preventing the upper tray from falling due to shaking. At the same time, due to the design of the tray being wide at the top and narrow at the bottom, when they are stacked up and down, the upper tray will not squeeze the polarizer in the lower tray.

[0030] The above-mentioned direction in which the profile extends along the side length of the bottom plate 1 is defined as the length, the direction in which the profile is away from the edge of the bottom plate 1 is defined as the width, and the distance between the upper surface of the protrusion 204 and the lower surface of the placement groove 201 is defined as the height.

[0031] Furthermore, the bottom plate 1 is made of a honeycomb plate made of PP material, and the first baffle 2 and the second baffle 3 are both made of PVC material. Since PP material and PVC material themselves have the characteristics of light weight and good hardness, they are not easily deformed and are easy to carry.

[0032] As a preferred solution, one end of the profile is inclined at 45 degrees, and the other end is inclined at 135 degrees, which is convenient for workers to process the profile and easy to assemble into a rectangle.

[0033] The specific installation process is as follows: first, install one of the first stoppers 2 on the base plate 1, and then respectively embed one end of the two L-shaped connecting blocks 4 into the positioning cavities 202 at both ends of the first stopper 2, and then install the second stopper 3 on the base plate, and at the same time, embed the other end of the L-shaped connecting block 4 into one end of the positioning cavity 202 of the second stopper 3, and then respectively install L-shaped connecting blocks 4 at both ends of the positioning cavity 202 in the other first stopper 2, and install the other first stopper 2 on the base plate 1, and at the same time, embed the other end of the L-shaped connecting block 4 installed in the positioning cavity 202 of the other first stopper 2 into the other end of the positioning cavity 202 in the second stopper 3, so that the base plate 1 and the two first stoppers 2 and the two second stoppers 3 form a rectangular trough body; finally, the profile and the L-shaped connecting block are fixedly connected by the locking screws 5.

[0034] Compared with the prior art, the utility model has the following advantages:

[0035] (1) A honeycomb board made of PP material is used as the bearing bottom, and a first stopper 2 and a second stopper 3 made of PVC material are embedded around the board, and the board is connected into a rectangle through an L-shaped connecting block 4, so as to form a rectangular trough for placing a polarizer for TFT-LCD. The structure is simple, light, and easy to carry;

[0036] (2) A positioning cavity 202 adapted to the L-shaped connecting block 4 is provided on the profile, and the two are fixed by a locking screw 5, which is convenient for assembly, can be recycled for many times, saves costs, and can hide the connecting parts, thereby improving the appearance;

[0037] (3) A hand buckle groove 205 is provided on the side of the profile to facilitate transportation;

[0038] (4) By providing a reinforcing portion 203 above the positioning cavity 202, the strength is increased and bending deformation is not easily generated; and the width of the upper surface of the reinforcing portion 203 is greater than the width of the lower surface of the placement groove 201, so that the product will not be squeezed when the trays are stacked, thereby ensuring the performance of the product itself.

[0039] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
