[0030] See also Figures 1 to 3 The utility model provides a plate corner connector, comprising a first clamping plate assembly 1, a second clamping plate assembly 2 and a connector 3;

[0031] The first cardboard assembly 1 is connected to the connecting member 3, the second cardboard assembly 2 is connected to the connecting member 3, and the first cardboard assembly 1 and the second cardboard assembly 2 are arranged at an angle;

[0032] The first card board assembly 1 and the second card board assembly 2 both include an inner card board 10 and an outer card board 20, and the inner card board 10 and the outer card board 20 are both connected to the connecting member 3. The inner card board 10 and the outer card board 20 are spaced apart, and the end of the outer card board 20 away from the connecting member 3 is tilted toward the direction of the inner card board 10.

[0033] Specifically, in the present embodiment, the first card board assembly 1 and the second card board assembly 2 are connected by a connecting piece 3 and are arranged at 90 degrees, the first card board assembly 1 is used to clamp the first external plate 100, and the second card board assembly 2 is used to clamp the second external plate 200, the first card board assembly 1 and the second card board assembly 2 both include an inner card board 10 and an outer card board 20, and the free end of the outer card board 20 is inclined toward the direction close to the inner card board 10, that is, the distance between the inner card board 10 and the outer card board 20 gradually decreases in the process of moving away from and approaching the connecting piece 3, and this structure makes the elastic deformation force of the outer card board 20 relative to the inner card board 10 gradually increase, that is, during the assembly process, it is easy to push the first plate 100 or the second plate 200 into the gap between the inner card board 10 and the outer card board 20, which is convenient for assembly, and at the same time, the structure of the outer card board 20 gradually inclined toward the inner card board 10 increases the clamping force of clamping the first plate 100 or clamping the second plate 200, thereby improving the stability of the connection.

[0034] By setting a plate corner connector composed of a first pallet assembly 1, a second pallet assembly 2 and a connector 3, the first pallet assembly 1 and the second pallet assembly 2 both include an inner pallet 10 and an outer pallet 20, and the inner pallet 10 and the outer pallet 20 are both connected to the connector 3. The free end of the outer pallet 20 is inclined toward the inner pallet 10, so that the distance between the outer pallet 20 and the inner pallet 10 gradually decreases in the direction away from the connector 3, thereby increasing the contact area between the outer pallet 20 and the external plate, reducing the production cost while improving the connection stability and sealing.

[0035] The outer card plate 20 includes a first outer body 21 and a second outer body 22 connected in sequence, one end of the first outer body 21 is connected to the connecting piece 3, and the other end of the first outer body 21 forms a bayonet 4 with the inner card plate 10, and the radial specification of the bayonet 4 is smaller than the distance from any other point of the first outer body 21 to any point of the inner card plate 10, and the second outer body 22 is arranged in a direction away from the inner card plate 10. Preferably, the end of the first outer body 21 away from the connecting piece 3 is inclined toward the inner card plate 10, and the distance from the connection between the second outer body 22 and the first outer body 21 to the inner card plate 10 is the smallest to form the bayonet 4, and the free end of the second outer body 22 is inclined in a direction away from the inner card plate 10. The setting of the second outer body 22 increases the structural strength of the outer card plate 20 and further improves the service life of the outer card plate 20.

[0036] The first outer body 21 is flat, the second outer body 22 is arc-shaped, the second outer body 22 and the inner clamping plate 10 form an entrance, and the arc-shaped structure of the second outer body 22 makes the entrance larger in diameter, making it convenient to push the first plate 100 or the second plate 200 into the clamping port 4 for easy assembly.

[0037] The inner card plate 10 includes a first inner body 11 and a second inner body 12 connected in sequence, the first inner body 11 is connected to the connecting member 3 , and the second inner body 12 is arranged in a direction away from the outer card plate 20 .

[0039] The inner card plate 10 is provided with a convex portion 13, and the convex portion 13 is arranged away from the outer card plate 20. The cross section of the convex portion 13 is semicircular, which increases the deformation resistance of the inner card plate 10 and improves the service life of the corner connector.

[0040] The length specification of the inner clamping plate 10 is greater than that of the outer clamping plate 20 , thereby increasing the contact surface between the corner connector and the first plate 100 or the second plate 200 outside.

[0041] The first cardboard assembly 1, the second cardboard assembly 2 and the connector 3 are integrally formed from a soft rubber material (such as PVC), which provides a stronger connection, lower cost, and reduces assembly steps.
