[0023] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0024] like Figure 1 and Figure 2 As shown, a corner structure for assembling plates provided by the utility model includes a "T"-shaped plate 1, one side of the "T"-shaped plate 1 is open, a "T"-shaped groove 2 is provided inside the "T"-shaped plate 1, and the three ends of the "T"-shaped groove 2 are all open. A limiting structure 3 is provided on the inner wall of the "T"-shaped groove 2, and at least one group of limiting structures 3 is respectively provided on the three straight sections of the "T"-shaped groove 2. The limiting structure 3 presses the plate against the inner wall opposite to the "T"-shaped groove 2. Specifically, the limiting structure 3 includes at least two continuous arc-shaped protrusions 31, at least one arc-shaped recessed portion 32 is connected between the two arc-shaped protrusions 31, and both ends of the limiting structure 3 are fixedly connected to the inner wall of the "T"-shaped groove 2.

[0025] It should be noted that the "T"-shaped plate 1 of the present application includes two mutually perpendicular straight plates, one of which is vertically connected to the middle of the other straight plate. The "T"-shaped groove 2 of the present application is a groove body formed in the "T"-shaped plate 1 according to the contour shape of the "T"-shaped plate 1, and the groove body passes through the two straight plates.

[0026] It should be further explained that the material of the limiting structure 3 is elastic. The material of the limiting structure 3 includes one or more of plastic and metal. The limiting structure 3 of the present application is composed of at least two arc-shaped protrusions 31 and an arc-shaped recessed portion 32 facing the inside of the "T"-shaped groove 2. When the plate is inserted into the groove body, the arc-shaped protrusion 31 contacts the plate and applies a certain pressure to the plate, pressing the plate on the inner wall of the opposite side of the groove body, thereby achieving stable placement of the plate. The arc-shaped recessed portion 32 can enhance the deformation effect of the arc-shaped protrusion 31, improve the stability of the plate installation, and there are at least two contact points between the limiting structure 3 and the plate, avoiding the situation where the pressure of a single contact point is too large to damage the plate. Specifically, an inwardly protruding connection seat 4 is provided on the inner wall of the "T"-shaped groove 2, and the connection seat 4 is connected to the end of the limiting structure 3. Preferably, the distance between the arc-shaped protrusion 31 and the inner wall of the opposite side of the groove body is between 4.7mm and 4.8mm. This distance is mainly to adapt to the thickness of the plate, and can be adjusted according to needs in actual use.

[0027] It needs to be further explained that when a vertical board is installed on the "T"-shaped board 1, since the vertical board is located in the middle of another straight board, the other straight board and the vertical board together form a triangular structure, thereby improving the stability of the board placement.

[0028] Specifically, two of the three straight line segments of the "T"-shaped groove 2 are collinear, the third straight line segment is perpendicular to the two straight line segments, and one end of the third straight line segment is connected to the junction of the two straight line segments. A notch is provided at the junction of the two collinear straight line segments, the notch is arranged opposite to the third straight line segment, and the notch is connected to the groove body inside the third straight line segment. The notch allows the plate inserted into the third straight line segment to pass through, and when placed, the open side of the "T"-shaped plate 1 can be placed upward to improve the stability of placement. Furthermore, the plate can be inserted into the groove body inside the other two straight line segments, which improves the flexibility of plate placement.

[0029] The limiting structures 3 of the inner grooves of the two collinear straight segments are both arranged on the side walls close to the third straight segment. The outer contour of the "T"-shaped plate 1 is flat, and reinforcing ribs are arranged at the two angles of the "T"-shaped plate 1. The reinforcing ribs and the angle of the "T"-shaped plate 1 form a triangular structure, which improves the structural strength of the corner. A weight-reducing groove 5 is arranged on the outer wall of the "T"-shaped plate 1.

[0030] Preferably, the limiting structure 3 also includes bolts, and threaded holes matching the bolts are provided on the outer wall of the "T"-shaped slot 2. Bolts can further improve the stability of the plate installation, and bolts can be added or not according to actual conditions in actual use.
