It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined arbitrarily with each other.

[0030] Many specific details are set forth in the following description in order to provide a thorough understanding of this application. However, this application may be implemented in other ways different from those described herein. Therefore, the protection scope of this application is not limited by the specific embodiments disclosed below.

[0031] The connection structure provided by the embodiments of the present invention, as shown in Figures 1 to 8As shown, it is used to connect the adjacent first frame edge 1 and second frame edge 2 on the frame. One end of the second frame edge 2 is provided with a plug-in mating part 21, including: a connecting piece 3 fixed to one end of the first frame edge 1, with a plug-in part 31 provided at the end facing away from the first frame edge 1 (i.e., the outer end), and a through hole 32 provided on the end face facing away from one end of the first frame edge 1; a locking piece 4 having a locking tongue 41, swingably mounted on the connecting piece 3, and the reciprocating swing of the locking piece 4 can make the locking tongue 41 extend out of and retract into the through hole 32; and a mating piece 5 having a locking tongue mating part 51, for being fixedly installed in the plug-in mating part 21. Among them, the plug-in part 31 is inserted into the plug-in mating part 21 from the end face of the second frame edge 2, and the extended locking tongue 41 is stuck on the locking tongue mating part 51 to lock the plug-in part 31 and the plug-in mating part 21 together.

[0032] This connection structure is used to connect the adjacent first frame edge 1 and second frame edge 2 on the frame. The connecting piece 3 is fixed to one end of the first frame edge 1, and the mating piece 5 is fixedly installed in the plug-in mating part 21. When the first frame edge 1 and the second frame edge 2 are connected, the plug-in part 31 is inserted into the plug-in mating part 21 from the end face of the second frame edge 2. After being inserted in place, the locking tongue 41 extending out of the through hole 32 is stuck on the locking tongue mating part 51 to prevent the plug-in part 31 from moving reversely and disengaging from the plug-in mating part 21. Its connection method is simple, convenient, time-saving, and labor-saving, and after connection, the first frame edge 1 and the second frame edge 2 will not unlock and disconnect by themselves, and its practicability is better.

[0033] Among them, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the connection structure further includes: a return spring 6, arranged between the locking piece 4 and the connecting piece 3, for keeping the locking tongue 41 extending out of the through hole 32, so that after the first frame edge 1 and the second frame edge 2 are connected, the plug-in part 31 and the plug-in mating part 21 are locked, and the plug-in part 31 and the plug-in mating part 21 are prevented from loosening and disengaging.

[0034] Furthermore, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the locking piece 4 also has a positioning post 42 and a shaft hole. The shaft hole is located between the positioning post 42 and the locking tongue 41. A rotating shaft passes through the shaft hole and the connecting piece 3 to swingably mount the locking piece 4 on the connecting piece 3. One end of the return spring 6 presses against the side of the connecting piece 3 facing the first frame edge 1, and the other end presses against the positioning post 42, keeping the locking tongue 41 extending out from the through hole 32 toward the side of the mating piece 5. The connecting piece 3 can be a connecting block.

[0035] Further, as Figures 5 to 7As shown, the connecting member 3 may be provided with a concave cavity 33 that opens toward the first frame edge 1. A disassembly and assembly opening 34 may be provided on the cavity wall of the concave cavity 33. The locking member 4 and the return spring 6 may be installed in the concave cavity 33 through the disassembly and assembly opening 34, and the locking member 5 and the return spring 6 can also be disassembled through the disassembly and assembly opening 34 when damaged.

[0036] When disassembling the first frame edge 1 and the second frame edge 2, the positioning post 42 on the connecting member 3 can be pressed toward the locking member 4 side, so that the locking tongue 41 swings and retracts from the through hole 32, releasing the restraint of the locking tongue 41 on the locking tongue mating part 51. Then, the first frame edge 1 is moved in the reverse direction, so that the connecting member 3 is separated from the insertion mating part 21, and the separation of the first frame edge 1 and the second frame edge 2 is completed.

[0037] Specifically, as Figure 3 and Figure 4 shown, both the locking tongue mating part 51 and the locking tongue 41 have a guiding and assembling surface 9, and the guiding and assembling surface 9 can be a guiding arc surface or a guiding inclined surface, etc., to better realize the locking tongue 41 being stuck on the locking tongue mating part 51. The swinging stroke of the locking tongue 41 intersects with the mating stroke of the insertion part 31 and the insertion mating part 21 and interferes with each other to eliminate the degrees of freedom and achieve the purpose of locking. The locking tongue mating part 51 can be a locking boss or a locking groove, etc., the insertion part 31 is a through insertion slot, the insertion mating part 21 is a through insertion groove, the groove wall of the through insertion groove is inserted into the through insertion slot, and the locking member 4 can be fixed in the insertion mating part 21 by screws.

[0038] Furthermore, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 7 shown, one end of the connecting member 3 adjacent to the first frame edge 1 is provided with a mounting part 35, and the mounting part 35 is fixedly connected to the first frame edge 1. For example, if the mounting part 35 is a mounting plate, the mounting plate and the first frame edge 1 can be fixedly connected by means of screws, etc.

[0039] In an exemplary embodiment, as Figure 1 and Figure 2 shown, screw holes are provided on the mounting plate, insertion holes 11 are provided on the first frame edge 1, through holes are provided on the side wall of the insertion holes 11, the mounting plate is inserted into the insertion holes 11, and the screws pass through the through holes and are tightened in the screw holes. The screws can be arranged inside the first frame edge 1 and a pressing plate 7 is fixed. The pressing plate 7 forms a T-shaped guide rail on the first frame edge 1, and a decorative part 8 forming a T-shaped groove is stuck on the T-shaped guide rail, so that the screws are hidden inside the decorative part 8 to avoid the exposure of the screws, thereby improving the aesthetics of the assembled product. When unlocking, the decorative part 8 can be disassembled first, and then the locking member 4 is pressed to retract the locking tongue 41 into the through hole to unlock it from the locking tongue mating part 51.

[0040] In another exemplary embodiment, asFigures 4 to 7 A position adjustment long hole 36 is provided on the shown mounting plate, and screw holes are provided on the first frame side 1. The screw passes through the position adjustment long hole 36 and is tightened in the screw hole. The length of the connecting member 3 extending from the end of the first frame side 1 can be adjusted by adjusting the position of the screw in the position adjustment long hole 36. In this way, the equivalent length of the first frame side 1 can be adjusted, and it can better adapt to the situation of a skew wall surface. The mounting plate is fixed on the first frame side 1 and forms a T-shaped guide rail on the first frame side. The decorative member 8 forming a T-shaped groove is stuck on the T-shaped guide rail (it can be limited by a limiting structure 10. The limiting structure 10 includes a limiting post and a concave point. The limiting post slides into the concave point for limiting to prevent the decorative member from sliding arbitrarily on the mounting plate. The limiting post is located on the decorative member, and the concave point is located on the mounting plate). When unlocking, the decorative member 8 can be removed first, and then the locking member 4 is pressed to retract the lock tongue 41 into the through hole to unlock it from the lock tongue mating part 51.
