It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] An aluminum alloy curtain wall crossbeam connector, comprising a connection block body 1. Both the left and right upper parts of the connection block body 1 are fixedly connected with first clamping blocks 2. Front and rear through first clamping grooves 3 are opened in the lower parts of the fronts of the two first clamping blocks 2. Front and rear through second clamping grooves 4 are opened in the upper parts of the fronts of the two first clamping blocks 2. A second clamping block 5 is fixedly connected to the middle of the upper end of the connection block body 1. A third clamping groove 13 is opened in the upper part of the second clamping block 5. A clamping plate 6 is jointly clamped in the two first clamping grooves 3. A fixing plate 7 is fixedly connected to the inner sides of the two clamping plates 6. First extension plates 8 are fixedly connected to both the left and right upper parts of the upper end of the fixing plate 7. First screw holes 9 are opened in the front and rear upper parts of the two first extension plates 8. Second extension plates 10 are fixedly connected to the inner sides of the two first extension plates 8. Second screw holes 11 are opened in the middle of the upper ends of the two second extension plates 10. A third clamping block 12 is fixedly connected to the inner lower wall of the fixing plate 7.

[0027] In this embodiment, an elastic buffer pad is provided at the upper end of the second clamping block 5. When the aluminum alloy curtain wall is subjected to external force impact or vibration, the elastic buffer pad can absorb part of the energy, reduce the impact force, thereby reducing the damage to the connecting piece and the curtain wall structure; anti-slip lines are provided on the outer side surface of the clamping plate 6, and the anti-slip lines can increase the friction between the clamping plate 6 and the first clamping groove 3, making the connection of the clamping plate 6 in the clamping groove more stable and preventing the clamping plate 6 from accidentally sliding or falling off during use; corrosion-resistant coatings are applied on the outer surfaces of the first extension plate 8 and the second extension plate 10. The corrosion-resistant coatings can effectively isolate the first extension plate 8 and the second extension plate 10 from contact with the external environment, prevent corrosive substances such as moisture, oxygen, and chemicals from eroding the plate body. By preventing corrosion, the corrosion-resistant coatings can maintain the structural integrity and performance stability of the first extension plate 8 and the second extension plate 10, reduce damage and failure caused by corrosion, and thus extend their service life; the two first extension plates 8, the two first screw holes 9, the two second extension plates 10, and the two second screw holes 11 are all distributed in a left-right mirror image. Specifically, the left-right mirror image distribution means that these components are symmetric in the left-right direction. That is to say, if the entire connecting piece is flipped 180 degrees along the central axis, the positions and shapes of these components on the left and right sides will be exactly the same. The left-right symmetric distribution can make the connecting piece more balanced during use, reducing deformation or damage caused by uneven force; the third clamping block 12 is clamped in the third clamping groove 13. The clamping method can make the third clamping block 12 and the third clamping groove 13 closely combined, providing additional support and fixation. This connection method can share and transfer shear forces, increase the shear resistance of the connecting piece, improve its load-bearing capacity, and the clamping design is usually relatively simple, facilitating installation and disassembly, which is beneficial to the maintenance and replacement of the connecting piece.

[0028] It should be noted that the present utility model is a crossbeam connecting piece for an aluminum alloy curtain wall. During the specific use process, first, the connecting block body 1 is fixed on the crossbeam of the aluminum alloy curtain wall. The first clamping block 2 and the second clamping block 5 at the upper end of the connecting block body 1 are used to connect with other components. The clamping plate 6 is inserted into the first clamping groove 3 of the two first clamping blocks 2, and the fixing plate 7 fixedly connected to the inner side surface of the clamping plate 6 is used to fix other components of the curtain wall. The first extension plate 8 and the second extension plate 10 at the upper end of the fixing plate 7 are respectively connected to other components through the first screw hole 9 and the second screw hole 11 to realize the installation and fixation of the curtain wall. The third clamping block 12 is clamped in the third clamping groove 13, increasing the overall connection stability. In addition, the elastic buffer pad at the upper end of the second clamping block 5 can play a buffering role during connection, reducing vibration and noise; the anti-slip lines on the outer side surface of the clamping plate 6 can increase friction and improve the reliability of the connection; the corrosion-resistant coatings on the outer surfaces of the first extension plate 8 and the second extension plate 10 can prevent corrosion and extend the service life. Through the above structure, the crossbeam connecting piece of the aluminum alloy curtain wall realizes the stable connection and installation of the curtain wall crossbeam, and at the same time has a certain adaptability and versatility.

[0029] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification is only to illustrate the principle of the present utility model.
