DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Example 1: A concealed connector. Please refer to Figures 1 - 3 , including: a concealed connector 101. The concealed connector 101 is L-shaped as a whole. The outer side of the concealed connector 101 is the bottom surface 3, and the identification scale 10 is arranged on the bottom surface 3. When the profile is sleeved onto the concealed connector 101, the depth of the profile sleeved can be judged through the identification scale 10. The inner side of the concealed connector 101 is the positioning surface 5, and twelve magnetic parts 9 are arranged on the positioning surface 5. The twelve magnetic parts 9 are symmetrically distributed on the positioning surface 5. After the profile is sleeved onto the concealed connector 101, the magnetic parts 9 adsorb the two sides inside the profile, playing a role of auxiliary fixation. Two bumps 102 are arranged on both sides of the concealed connector 101. The overall structure cross-section formed by the concealed connector 101 and the two bumps 102 is a cross shape. Through the cooperation of the connector 101 and the two bumps 102, it can be ensured that the profile is in the centered state when sleeved onto the concealed connector 101. An avoidance space 6 is arranged between the two bumps 102 on the concealed connector 101. The avoidance space 6 is used to provide space for connecting two profiles. The two sides of the bump 102 are the contact surfaces 1, and the side away from the concealed connector 101 of the bump 102 is the side surface 2. Four threaded surfaces 4 are arranged on the concealed connector 101, and a setscrew 401 is arranged in the threaded surface 4 in a threaded manner.

[0022] When connecting two profiles, by sleeving the two profiles on both ends of the concealed connector 101, the bumps 102 slide in the opening grooves at the ends of the profiles, and the profile interior is contacted through the side surface 2 and the contact surface 1, so that the concealed connector 101 is close to the center position of the profile during installation. Then, the position of the profile and the concealed connector 101 is adjusted to align the threaded surface 4 of the concealed connector 101 with the installation hole of the profile, and the contact surface 1 and the positioning surface 5 are tightly attached to the inner wall of the cavity of the profile, so that the concealed connector 1 can be accurately positioned at the center position of the profile slot opening, facilitating the connection of the profile and the concealed connector 1. Subsequently, the setscrew 401 is passed through the installation hole of the profile and the threaded surface 4 of the concealed connector 101, and the setscrew 401 is rotated to fix the concealed connector 101 and the profile. The two profiles are connected at the avoidance space 6, so that the avoidance space 6 is applicable to applications with different connection methods, increasing the utilization rate of this product.

[0023] Example 2: On the basis of Example 1, please refer to Figure 3 , and a number of ball catches 7 are slidably arranged on the contact surface 1. The ball catches 7 are clamped with the profile, and an elastic member 8 is connected between the ball catches 7 and the concealed connector 101.

[0024] When a connecting member is needed, the hidden connecting member is placed in the profile groove, causing the profile extrusion clamping balls 7 to move towards the side where they approach each other, and the elastic member 8 is compressed accordingly. After the hidden connecting member is completely placed inside the profile, the elastic member 8 returns to its original state, causing the clamping balls 7 to move towards the side where they move away from each other and engage with the profile, thereby completely fixing the hidden connecting member inside the profile and preventing the hidden connecting member from moving.

[0025] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
