[0024] The novel door and window center column connector of the present invention comprises a center column sleeve 10, a pull code assembly 11 and a center column 12. Figure 1 The front view of the connection structure of the present invention, Figure 2 The side view of the connection structure diagram of the present invention is shown in the figure. Preferably, the middle column 12 contains a T-shaped chamber, and the T-shaped chamber is provided with a head end chamber and a tail end chamber. The cross-sectional shape of the middle column sleeve 10 matches the cross-sectional shape of the head end chamber, and the middle column sleeve 10 is inserted in the head end chamber. In one embodiment of the present invention, a separator 13 is provided in the T-shaped chamber, and the separator 13 separates the T-shaped chamber into a first inner chamber 121 and a second inner chamber 122. The cross-sectional shapes of the head end chambers of the first inner chamber 121 and the second inner chamber 122 are the same. Preferably, two middle column sleeves 10 are inserted in the head end chamber; the separator 13 has a connecting hole 120 (shown in the figure as the location of the convex column).

[0025] It also includes a pull-code assembly 11, which includes a pull-code block 100 inserted into the tail end cavity, which is a ring-shaped structure with a rectangular cross section, a convex portion is provided on one side of the pull-code block 100 and engages with the connecting hole 120, and its opposite side abuts against the frame of the middle column, and a fixing rod is provided on the other side of the pull-code block 100 in the same direction as the extension direction of the middle column, and its extended distal end is fixedly connected to the frame 600. In a preferred embodiment, the middle column sleeve 10 and the pull-code block 100 are arranged against each other, and both are inserted in the first inner chamber 121.

[0026] Please also read Figure 4A-4CThe front view, right view and top view of the center column sleeve, the cross-sectional shape of the center column sleeve 10 matches the second inner chamber 122, it is fixed on the frame 600, and is sleeved and installed in the second inner chamber 122 of the center column 12, and three screw holes are opened on the center column sleeve 10, and the screw holes are respectively distributed on each side of the center column sleeve 10 so that the twisting force it bears is maximized. Pre-fixing the center column sleeve can effectively prevent the center column 12 from rotating or deflecting due to the rotational force generated when the screw rod is rotated to tighten the pull code assembly 11, thereby affecting the installation accuracy and aesthetics of the center column of doors and windows.

[0027] As mentioned above, another important connecting component of the present invention is the pull code assembly. The structure of this component can be found in Figure 3A-3D The front view, top view, left view and right perspective view of the pull code assembly. The pull code assembly 11 includes the following components and structures. The pull code block 100, the pull code block 100 is integrally formed by a first frame 101 and a second frame 102 of a hollow structure, and the pull code block 100 surrounded by the first frame 101 and the second frame 102 preferably meets the following conditions: ① The front cross-section of the pull code block 100 is preferably a square ring structure; ② The width of the first frame 101 is greater than the width of the second frame 102.

[0028] Among them, a first through hole 1011 is provided on the top of the first frame body 101, a first accommodating space 1012 is provided below the first through hole 1011, first card slots 1013 are provided at the lower ends of the two side walls of the first accommodating space 1012, a top plate 2 is fixedly connected between the first card slots, and the length of the top plate 2 is equal to the thickness of the first frame body 101. A boss 3 is provided through the top of the first through hole 1011, the size of the boss 3 matches the connecting hole 120, a rib 31 is provided at the bottom of the boss 3, and the diameter of the rib 31 is larger than the diameter of the first through hole 1011. A spring 4 is connected between the top plate 2 and the rib 31, the top of the spring 4 is abutted against the bottom of the rib 31 or the top of the boss 3. Preferably, the spring 4 passes through the rib 31 and extends to the inner cavity of the boss 3 and contacts the top of the inner cavity. Figure 3C As shown in the left view of the pull code assembly, the spring 4 is preferably a conical spring. The spring 4, the boss 3, and the top plate 2 form an elastic system, which ensures both a stable elastic coefficient and a compression performance between the boss 3 and the top plate 2.

[0029] A second through hole 1021 is opened on the upper side wall of the second frame body 102, and an open second accommodating space 1022 is set in the inner cavity of the second frame body 102 opposite to the second through hole 1021, and the two side walls of the second accommodating space 1022 extend inwardly along relative directions with folded edges 1023; a nut 300 is clamped in the second accommodating space 1022, and the outer diameter of the nut 300 is equivalent to the height of the second accommodating space 1022, and the nut 300 is clamped in the second accommodating space 1022 and cannot rotate at will.

[0030] The pull-code assembly 11 further includes a screw 200 and a frame top column 400. One end of the screw 200 passes through the second through hole 1021 and the second accommodation space 1022 from the second frame 102 in sequence, and is screwed with a nut 300 disposed in the second accommodation space 1022. The other end of the screw 200 passes through a reserved hole of the frame 600 (not shown in the figure) and is fixed by a circular tube 500 and a nut 300. The frame top column 400 is sleeved on the screw 200. The length of the frame top column 400 is the same as the inner cavity of the frame 600. When installed, the frame top column 400 is located in the inner cavity of the frame 600.

[0031] In summary, the connection structure of the present invention can be summarized as follows: two center column sleeves are fixed to the frame using screws according to the position of the center column installation, the pull-code assembly is inserted into the inner cavity of the center column, so that the convex column in the pull-code assembly pops out of the circular hole pre-opened in the center column, and the entire pull-code assembly is stuck in the inner cavity of the center column; the center column together with the pull-code assembly is inserted into the installed center column sleeve, and the pull-code assembly is tightened with a screw nut outside the frame so that the center column is tightly attached to the frame.

[0032] According to the above structure and connection relationship, the technical effect produced by the present invention is as follows: the present invention uses a pull-code assembly and two center column sleeves to connect the center column and the frame. The pull-code assembly generates a lateral pulling force, so that the end face of the center column is tightly attached to the frame surface, and no gap is generated to affect the performance and aesthetics of the doors and windows; the two center column sleeves are installed in the inner cavity of the center column to prevent the center column from rotating or deflecting due to the rotational force generated when the screw is rotated to tighten the pull-code, thereby affecting the installation accuracy and aesthetics. This center column connection structure is easy and accurate to assemble, and it is easier to meet the installation requirements and installation accuracy of doors and windows, and it is safer and more reliable. It is especially suitable for the connection of the center columns of a larger series of doors and windows.
