A pull cord is usually set in the side rails, one end of the pull cord passes through the moving rail and connects to the top of the honeycomb fabric, and the other end of the pull cord passes through the corner connector and is finally connected to the tension adjustment component of the pull cord. Figure 6 The corner body 1' comprises a corner body 1', side panels 2' are formed on both sides of the corner body 1', and a horizontal plug 3' and a vertical plug 4' are formed on the corner body 1', wherein the upper side of the corner body 1' is flush with the upper side of the side panel 2', the rear side of the corner body 1' is flush with the rear side of the side panel 2', and the corner outer wall of the corner body 1' is flush with the corner of the side panel 2'. The disadvantages are: 1. When the entire manual honeycomb blind is installed in the window frame, the tail of the screw in the window frame is slightly protruding (the tail of the screw is not completely First, if the screw is fully screwed into the window frame and the tail of the screw is not flush with the inner wall of the window frame, it will press against the upper and rear sides of the corner body 1', thereby affecting the installation of the manual honeycomb blind; second, the window frame is usually formed by welding four stainless steel profiles, the inner walls of the four stainless steel profiles at the corners are prone to leaving protruding welding residues (slag inclusions) after welding, resulting in an uneven inner wall of the corner of the window frame. The protruding welding residues will press against the outer corner wall of the corner body 1', thereby affecting the installation of the manual honeycomb blind. Summary of the invention

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and to provide an improved corner connection device for honeycomb curtains, which is more convenient to install and does not interfere with the installation of the honeycomb curtains by the protruding screw tails and welding residues in the window frame under the premise of ensuring structural strength.

[0004] The utility model discloses a technical scheme of a corner connection device for an improved honeycomb blind: it comprises a corner body, side panels are formed on both sides of the corner body, a horizontal plug and a vertical plug are formed on the corner body, communicating threading grooves are formed in the corner body and the horizontal plug, a winding seat is formed on the threading groove of the main body, upper convex ribs protruding outwards are formed on the outer walls of both sides of the main body and the horizontal plug, upper grooves are formed between the upper convex ribs and the main body and the horizontal plug, rear convex ribs protruding outwards are formed on the outer walls of both sides of the main body and the vertical plug, rear grooves are formed between the rear convex ribs and the main body and the vertical plug.

[0014] The utility model relates to an improved corner connection device for honeycomb blinds, such as Figure 1 — Figure 5 As shown, it includes a corner body 1, side panels 2 are formed on both sides of the corner body, a horizontal plug 3 and a vertical plug 4 are formed on the corner body 1, and interconnected wire threading grooves 5 are formed in the corner body 1 and the horizontal plug 3. The main body 1 is provided with a winding seat 6 on the wire threading groove 5, and the outer walls of both sides of the main body 1 and the horizontal plug 3 are provided with upper convex ribs 7 protruding outwards, and upper grooves 8 are formed between the upper convex ribs 7 and the main body 1 and the horizontal plug 3. The outer walls of both sides of the main body 1 and the vertical plug 4 are provided with rear convex ribs 9 protruding outwards, and rear grooves 10 are formed between the rear convex ribs 9 and the main body 1 and the vertical plug 4.

[0015] Furthermore, a corner rib 11 is formed between the upper rib 7 and the rear rib 9. When there is welding residue on the inner wall of the corner of the window frame, since the welding residue is at the corner position and is difficult to remove by processing, the corner rib 11 can be partially cut off to leave space at the position to avoid interference of the welding residue on the installation of the manual honeycomb blind. The corner rib 11 is located on both sides and is in sheet form, which is convenient for cutting.

[0016] Further, a convex arc 12 is formed at a corner of the winding seat 6 near the vertical plug 4. With the convex arc 12, when the pull wire 110 is pulled, the pull wire 110 cooperates with it to reduce wear, and the pull wire 110 is pulled more smoothly.

[0017] The beneficial effects of the corner connection device of the improved honeycomb curtain of the utility model are as follows: the honeycomb curtain is mainly composed of side rails 101, upper and lower rails 102, shift rails 103 and honeycomb fabric (the attached figure shows the honeycomb fabric, the specific structure of the honeycomb fabric is mainly connected between the upper and lower rails 102 and the shift rails 103), etc., a corner connection device is arranged at the corner of the side rails 101 and the upper and lower rails 102, the horizontal plug 3 of the corner connection device is plug-connected with the upper and lower rails 102, the vertical plug 4 of the corner connection device is plug-connected with the side rails 101, and the upper and lower rails and the side rails are connected to form a frame of the honeycomb curtain through the corner connection device. The present scheme mainly makes the upper surface height of the corner body 1 and the horizontal plug 3 lower than the upper surface height of the side panel 2, and the corner body 1 and the horizontal plug 3 are provided with upper convex ribs 7 protruding upward on both sides, so that an upper groove 8 is formed between the upper convex rib 7 and the corner body 1 and the horizontal plug 3, the rear side surface of the corner body 1 and the outer surface of the vertical plug 4 are lower than the rear side height of the side panel 2, and the corner body 1 and the vertical plug 4 are provided with rear convex ribs 9 protruding backward on both sides, so that a rear groove 10 is formed between the rear convex rib 9 and the corner body 1 and the vertical plug 4, when the assembled honeycomb curtain is installed in the window frame, the protruding tail of the screw on the inner wall of the window frame can be stuck in the upper groove 8 and the rear groove 10, and the protruding tail of the screw in the window frame will not interfere with the installation of the honeycomb curtain, ensuring that the honeycomb curtain can be smoothly installed in the window frame, and the installation is more convenient.
