[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 A curtain wall post-anchor connection structure, comprising a main structure 1, a post-anchor, a metal plate 2 and an adapter 3, which has been disclosed in the reference document and will not be repeated here. The metal plate 2 is fixed to the outer wall of the main structure 1 by the post-anchor, and a slot is provided on the side of the metal plate 2 away from the main structure 1, and a support plate 9 is slidably inserted on the inner wall of the slot for supporting the adapter 3, one end of the support plate 9 passes through the slot, and the upper end of the support plate 9 is fixedly connected to the lower end of the adapter 3, and a rubber pad 10 is fixedly connected to the side of the adapter 3 close to the main structure 1 for reducing the wear between the adapter 3 and the metal plate 2;

[0023] In this embodiment, a plurality of support blocks 11 are fixedly connected to one side of the adapter 3 close to the metal plate 2, which are used to support the adapter 3. A storage groove is provided in the metal plate 2, and an opening corresponding to the support block 11 is provided on the inner side wall of the storage groove. One end of the support block 11 slides through the opening and extends into the storage groove. A wedge-shaped card slot is provided at the lower end of the support block 11. A moving block 7 is provided at the lower end of the support block 11, which is used to drive the card block 8 to move. The moving block 7 is slidably connected in the storage groove, and a card block 8 corresponding to the card slot is fixedly connected to the upper end of the moving block 7, which is used to prevent the support block 11 from loosening.

[0024] In this embodiment, a plurality of guide rods 13 are fixedly connected to the inner top of the storage groove, which are used to keep the moving block 7 moving in a straight line. The lower ends of the guide rods 13 slide through the plurality of moving blocks 7 in sequence and are fixedly connected to the inner bottom of the storage groove. Both ends of the moving block 7 are provided with arc grooves, and the inner side walls of the arc grooves are rollingly connected with balls 14, which are used to reduce the resistance of the moving block 7 when moving. Part of the balls 14 penetrates the arc grooves.

[0025] In this embodiment, a lead screw 6 is rotatably connected to the inner bottom of the storage groove, which is used to drive the moving block 7 to move. The upper end of the lead screw 6 sequentially penetrates a plurality of moving blocks 7 and is rotatably connected to the inner top of the storage groove. The lead screw 6 and the moving block 7 are threadedly connected. A worm wheel 5 is fixedly sleeved on the upper end of the lead screw 6 to drive the lead screw 6 to rotate. A worm 4 meshing with the worm wheel 5 is provided in the storage groove to drive the worm wheel 5 to rotate. One end of the worm 4 close to the main structure 1 is rotatably connected to the inner side wall of the storage groove. The other end of the worm 4 penetrates the metal plate 2 and is fixedly connected with a knob 12 to drive the worm 4 to rotate. The worm 4 and the metal plate 2 are rotatably connected. The end of the knob 12 away from the metal plate 2 is provided with an inner hexagonal groove, which is convenient for the user to use an electric inner hexagonal wrench to rotate the knob 12. The knob 12 and the worm 4 are both made of stainless steel to play a certain anti-rust role.

[0026] In this embodiment, first, an inner hexagonal wrench is inserted into the inner hexagonal slot to rotate the knob 12, and the knob 12 drives the worm 4 to rotate, and the meshing action of the worm 4 and the worm wheel 5 drives the lead screw 6 to rotate, and the lead screw 6 drives multiple moving blocks 7 to move up and down through the action of threaded meshing (the up and down movement is controlled by the user turning the knob 12 forward and reverse). When the moving block 7 moves upward, it will drive the card block 8 to insert into the card slot, thereby preventing the support block 11 from loosening, and then fixing the position of the adapter 3. At the same time, after the card block 8 is inserted into the card slot, it abuts against the wedge surface in the card slot, thereby pushing the support block 11 to move down into the storage slot, and the adapter 3 is driven by the support block 11 to fit tightly with the metal plate 2, thereby improving the tightness of the adapter 3. When the moving block 7 moves downward, it will drive the card block 8 to disengage from the card slot. At this time, the adapter 3 can be removed by pulling it.
