The side mounting through holes 2511 of the first side door frame bar 25 and the second side door frame bar 26 are hidden in the grooves 251, realizing a concealed design of the mounting screws, making the first folding door panel 2 and the second folding door panel 3 more beautiful.

[0048] In the specific application of the present utility model, the assembly process of the first folding door panel 2 and the second folding door panel 3 includes: first, connecting corner brackets at both ends of the first side door frame bar 25 and the second side door frame bar 26 respectively; for distinction, the corner bracket connected to the top end of the first side door frame bar 25 is called the first corner bracket, the corner bracket connected to the bottom end of the first side door frame bar 25 is called the second corner bracket, the corner bracket connected to the top end of the second side door frame bar 26 is called the third corner bracket, and the corner bracket connected to the bottom end of the second side door frame bar 26 is called the fourth corner bracket.

[0049] The first connecting arm 271 of the first corner bracket, the first connecting arm 271 of the second corner bracket and the side mounting through hole 2511 at the proximal end of the top of the first side door frame bar 25 are screw-assembled and connected; the first connecting arm 271 of the third corner bracket, the first connecting arm 271 of the fourth corner bracket and the side mounting through hole 2511 at the proximal end of the bottom of the second side door frame bar 26 are screw-assembled and connected. The two sides of the door leaf 21 are respectively inserted into the sealing strips 24 on the corresponding side. The first sealing groove 2710 of the first corner bracket, the first sealing groove 2710 of the second corner bracket and the top of the door leaf form a complete top sealing strip receiving groove; the second sealing groove 2720 of the first corner bracket, the second sealing groove 2720 of the third corner bracket and the first side of the door leaf 21 form a complete first side sealing strip receiving groove; the first sealing groove 2710 of the third corner bracket, the first sealing groove 2710 of the fourth corner bracket and the second side of the door leaf form a complete second side sealing strip receiving groove; the second sealing groove 2720 of the second corner bracket, the second sealing groove 2720 of the fourth corner bracket and the bottom of the door leaf 21 form a complete bottom sealing strip receiving groove.

[0050] Subsequently, insert the first sealing strip 24 into the top sealing strip receiving groove from the sealing strip mounting hole 270 of the first corner bracket; insert the second sealing strip 24 into the first side sealing strip receiving groove from the sealing strip mounting hole 270 of the second corner bracket; insert the third sealing strip 24 into the bottom sealing strip receiving groove from the sealing strip mounting hole 270 of the fourth corner bracket; insert the fourth sealing strip 24 into the second side sealing strip receiving groove from the sealing strip mounting hole 270 of the fourth corner bracket, so that the four sealing strips 24 are connected end to end.

[0051] Finally, place the top door frame strip 22 on the tops of the first side door frame strip 25 and the second side door frame strip 26. Screw-connect one end of the top door frame strip 22 to the second connecting arm 272 of the first corner fitting, and connect the other end of the top door frame strip 22 to the second connecting arm 272 of the third corner fitting. Then, place the bottom door frame strip 23 on the bottoms of the first side door frame strip 25 and the second side door frame strip 26. Screw-connect one end of the bottom door frame strip 23 to the second connecting arm 272 of the second corner fitting, and connect the other end of the bottom door frame strip 23 to the second connecting arm 272 of the fourth corner fitting, thus completing the installation of the assembled door.

[0052] Specifically, the pulley assembly 30 includes a transmission rod 301, a connecting block 302, and a plurality of rollers 303. One end of the transmission rod 301 is connected to the second folding door panel 3, the other end of the transmission rod 301 is connected to the connecting block 302, the connecting block 302 is disposed in the track groove 10, and a plurality of rollers 303 are respectively rotatably assembled on both sides of the connecting block 302; roller grooves are respectively provided on both sides of the groove wall of the track groove 10, and the rollers 303 are disposed in the roller grooves.

[0053] With the above structure, when closing or opening the door, the second folding door panel 3 drives the transmission rod 301 to move. Since the upper end of the transmission rod 301 is connected to the connecting block 302 and the rollers 303 can roll in the roller grooves, stable guidance is provided for the folding door, ensuring that the door can move along a predetermined path when opening and closing, guaranteeing the smooth operation of the door. Moreover, the roller 303 structure can make the movement of the connecting block 302 smoother, reduce the situation of jamming, and improve the user experience.

[0054] Specifically, convex strips 2712 are respectively provided at the bottoms of the first sealing groove 2710 and the second sealing groove 2720. The convex strips 2712 are arranged along the length direction of the first sealing groove 2710 or the second sealing groove 2720, and the mounting screw holes 2711 penetrate through the convex strips 2712.

[0055] With the above structure, the thickness of the first connecting arm 271 and the second connecting arm 272 can be increased, thereby increasing the length of the mounting screw holes 2711, enabling the mounting screw holes 2711 to have sufficient space to set threads, ensuring that sufficient friction and pressure can be generated between the mounting screw holes 2711 and the fixing screws so that the two components are tightly connected together. By providing the convex strips 2712, while ensuring the connection strength, the weight of the corner fitting can also be reduced.

[0056] Optionally, the first connecting arm 271, the second connecting arm 272, and the baffle 273 are integrally formed.

[0057] In a specific embodiment of the present invention, the angle code is integrally formed by die-casting, and the first connecting arm 271, the second connecting arm 272 and the baffle 273 are formed by a die-casting alloy, thereby ensuring the strength of the angle code; moreover, by die-casting, a through hole can be formed on the first connecting arm 271 and the second connecting arm 272, and then a thread is set on the through hole to form a mounting screw hole 2711, and the subsequent process of opening the mounting screw hole 2711 on the angle code is omitted, thereby avoiding deviations in the subsequent hole turning process, which leads to the problem of being unable to be assembled with the door frame strip.

[0058] Specifically, the first avoidance gap and the second avoidance gap are provided with an inclined surface 2713 along one side of the length direction, and the inclined surface 2713 is inclined outward.

[0059] The inclined surface 2713 plays a guiding role. With the above structure, it is convenient for the staff to insert the sealing strip 24 into the first sealing groove 2710 / the second sealing groove 2720.

[0060] Specifically, the door frame 1, the door leaf 21, the top door frame strip 22, the bottom door frame strip 23, the sealing strip 24, the first side door frame strip 25, the second side door frame strip 26 and the corner code 27 are all made of aluminum alloy.

[0061] In a specific embodiment of the present invention, the door frame 1, the door leaf 21, the top door frame strip 22, the bottom door frame strip 23, the sealing strip 24, the first side door frame strip 25, the second side door frame strip 26 and the corner code 27 are all made of aluminum alloy; while maintaining strength, the weight is reduced, and it is easy to process and has good corrosion resistance.

[0062] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
