[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] In the description of the present invention, it should be noted that the terms "center", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0025] Furthermore, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances. Example

[0026] Reference Figure 1 and Figure 3As shown, this embodiment describes in detail a quick installation structure of a rectangular frame, which includes two sets of profiles 2 of different lengths and a connector 1; the two sets of profiles of different lengths respectively form the long and short frames of the frame, and the long and short frames are connected at the corners by the connector 1; in this embodiment, the long and short frames have the same cross-sectional structure. Figure 2 and Figure 3 As shown, a through cavity 22 is provided in the profile 1 along the length direction, and a plurality of mounting through holes 21 penetrating the inside and outside of the profile are uniformly distributed along the length direction.

[0027] like Figure 3 and Figure 4 As shown: the connecting piece is provided with a transition section 12 and a connecting section 11 connected to the transition section; in this embodiment, the two connecting sections 11 form a right-angle connection structure through the transition section 12; of course, through the design of the transition section 12, the two connecting sections 11 can form any angle, which will not be discussed here one by one. In order to save costs and meet the needs of structural design, as Figure 3 and Figure 4 As shown: the connecting section 11 of this embodiment is a hollow structure, and the hollow cavity is divided into an inner cavity 15 and an outer cavity 14 by a support plate 13; in order to install the locking mechanism, a connecting hole is provided on the inner wall of the inner cavity.

[0028] like Figure 2 As shown, since the connecting section 11 needs to be inserted into the through cavity 22 of the profile when connected, the external structure of the connecting section 11 matches the cross section of the through cavity 22 of the profile.

[0029] like Figure 5 As shown: the locking mechanism 3 involved in this embodiment includes a fixed carrier 31, a positioning tongue 32 and a flip cover 34, the fixed carrier 31 is a circular base; the positioning tongue 32 includes a cylindrical body 321 and a convex ring 322 formed by radius contraction, the positioning tongue 32 is sleeved on the circular base through the cylindrical body 321, and the circular base has a certain height; the convex ring 322 is provided with a flip cover 34, and the flip cover 34 is connected to the convex ring through a positioning pin 33; by touching the flip cover 34, the flip cover can be rotated around the positioning pin 33 and erected, so that the flip cover 34 can be rotated to rotate the positioning tongue 32, thereby achieving the purpose of tool-free operation.

[0030] like Figure 4 As shown, the bottom of the fixed carrier 31 is fixed to the support plate 13 by screws 4, and the positioning tongue 32 is threadedly connected to the fixed carrier 31. The positioning tongue is located opposite the connecting hole so that the convex ring of the positioning tongue can quickly penetrate.

[0031] In order to prevent the positioning tongue 32 from falling off from the fixed carrier 31, this embodiment reduces the radius of the mounting hole 21 and matches the radius of the mounting hole 21 with the radius of the convex ring 322 of the positioning tongue. In this way, when the convex ring 322 protrudes outward through the connecting hole and the mounting hole 21, the cylindrical body 321 of the positioning tongue has a larger radius and cannot pass through the mounting hole 21. In this way, the protruding position of the positioning tongue is locked to achieve the above purpose.

[0032] like Figure 2 As shown: when the connector 1 is connected to the profile 2, the connecting section 11 of the connector is inserted into the through cavity 22 of the profile, and the positioning tongue 32 is rotated so that the convex ring of the positioning tongue protrudes outward through the connecting hole and the mounting through hole 21 of the profile, thereby realizing the connection between the connector 1 and the profile 2.

[0033] For easy and beautiful installation, a positioning step is provided between the connecting section 11 and the transition section 12. The distance from the center position of the connecting hole on the connecting section 11 to the positioning step matches the distance from the center of the mounting through hole set on the profile 2 to the end of the profile on the same side, so that when the connecting section 11 is inserted into the final position, the connecting hole corresponds exactly to the position of the set mounting through hole 21.

[0034] One connection hole is provided on the connection section 11 to simplify the structure. In order to make the connection more secure, the number of connection holes can be increased so that multiple locking mechanisms 3 can be installed. Example

[0035] like Figure 6 and Figure 7 As shown, this embodiment 2 changes the locking mechanism 3 on the basis of embodiment 1. The locking mechanism includes a fixed carrier 31 and a positioning tongue 32. The positioning tongue includes a cylinder body 321 and a convex ring 322 formed by radius contraction. The outer end of the convex ring 322 forms a closed end face, and a handle 323 is formed on the closed end face, so that the positioning tongue 32 can be directly rotated by the handle 323.

[0036] When assembling the utility model, first fix the locking mechanism 3 in the connecting hole, then insert the connecting section into the corresponding frame profile, and manually rotate the positioning tongue counterclockwise until it presses against the profile. When disassembling, rotate the positioning tongue clockwise to the corresponding position.

[0037] In order to further improve the lock assembly efficiency, the threads between the fixed carrier and the positioning tongue adopt a large pitch structure, thereby reducing the round-trip movement distance.

[0038] Obviously, the embodiments described above are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
