Description

Technical Field

[0001] This invention belongs to the technical field of curtain wall connectors, specifically, it relates to an aluminum alloy curtain wall connector. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It is hung up like a curtain, hence the name "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings, consisting of panels and a connecting structural system.

[0003] During the installation of curtain walls, special connectors are required to connect the curtain wall to the building. Among them, aluminum alloy connectors are widely used due to their strong corrosion resistance and light weight.

[0004] Existing curtain wall connectors typically consist of two parts. The first part connects to the building wall, while the curtain wall connects to the second part, which is mounted on the first part to achieve the connection between the curtain wall and the building wall. However, during actual installation, the horizontal alignment of the sides of the curtain wall can easily become misaligned, as shown in the instruction manual. Figure 9 As shown, misalignment requires manual adjustment, and since curtain walls are usually heavy, manual adjustment is very laborious, which also greatly reduces the installation efficiency of the curtain wall. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an aluminum alloy curtain wall connector that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: an aluminum alloy curtain wall connector, comprising an L-shaped plate integrally formed from a horizontal part and a vertical part, and further comprising: a buckle plate, the buckle plate comprising a wall panel and an N-shaped buckle groove plate and a lower part connected to both ends of the wall panel, the N-shaped buckle groove plate having a slot, the buckle plate being connected to the vertical part of the L-shaped plate through the slot; a ratchet assembly, disposed on the buckle plate, the ratchet assembly being connected to a gear, a toothed assembly and a limiting plate being respectively disposed on one side of the vertical part of the L-shaped plate, when the buckle plate moves from one side of the L-shaped plate to the other side of the L-shaped plate, the gear meshes with the toothed assembly and rotates, when the gear reaches the limiting plate, the movement of the buckle plate stops, and the buckle plate is locked by the ratchet assembly; fixing bolts and nuts for connecting the L-shaped plate; and an anti-loosening assembly, disposed on the buckle plate, for locking the nuts after the ratchet assembly locks the buckle plate on the L-shaped plate.

[0007] Preferably, the ratchet assembly includes an outer ratchet disc, an inner ratchet disc, ratchet teeth, and a connecting shaft. The ratchet teeth are rotatably connected to the inner ratchet disc via a torsion spring, and the ratchet teeth mesh with the ratchet teeth in the outer ratchet disc. The connecting shaft is fixedly connected to the inner ratchet disc. The inner ratchet disc is rotatably disposed within the outer ratchet disc. A connecting plate is mounted on the buckle plate, and the outer ratchet disc is mounted on the connecting plate. The gear is fixedly connected to the connecting shaft.

[0008] Furthermore, it also includes a mounting plate installed on one side of the vertical portion of the L-shaped plate, wherein the tooth assembly and the limiting plate are both mounted on the mounting plate.

[0009] Preferably, the anti-loosening component includes a rubber wheel fixedly connected to the connecting shaft, with multiple protrusions fixedly connected to the outer circumference of the rubber wheel, and a groove provided on the outer circumference of the nut, with the protrusions corresponding to the groove.

[0010] Preferably, the anti-loosening component includes a rubber wheel fixedly connected to the connecting shaft, with multiple protrusions fixedly connected to the outer circumference of the rubber wheel, and external teeth fixedly connected to the outer circumference of the nut, the external teeth corresponding to the protrusions on the outer circumference of the rubber wheel.

[0011] Furthermore, the N-type groove plate is threaded with an adjusting bolt.

[0012] Furthermore, a first mounting groove is provided on the inner wall of the N-shaped fastening plate, and a rubber pad is installed in the first mounting groove to fill the gap between the N-shaped fastening plate and the vertical part.

[0013] Furthermore, a second mounting groove is provided on the lower part, and the rubber pad is located in the second mounting groove.

[0014] Furthermore, anti-slip stripes are provided on the horizontal surface of the L-shaped plate and on the inner sidewall of the plate.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: When installing the curtain wall panel, the present invention only needs to push the curtain wall panel to move, and uses the limiting plate to limit the movement stroke of the buckle plate, so that the curtain wall panel is locked in a uniform position. This prevents the side of the curtain wall panel from being misaligned when installing the curtain wall panel in a row. Furthermore, through the ratchet assembly, after the gear on the buckle plate reaches the limiting plate, the ratchet assembly prevents the buckle plate from moving in the opposite direction, thereby locking the curtain wall panel and avoiding lateral displacement after the curtain wall panel is installed, thus effectively improving the installation efficiency of the curtain wall panel.

[0016] Furthermore, by using the anti-loosening components installed on the buckle plate in conjunction with the movement of the buckle plate on the L-shaped plate, the nuts on the fixing bolts on the L-shaped plate are locked and limited in a coordinated manner, which can effectively prevent the nuts from loosening and avoid loosening between the L-shaped plate and the building wall.

[0017] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 The technical solutions provided in the various embodiments of the present invention will be described in detail.

[0031] Example 1: Refer to Figures 1-9 An aluminum alloy curtain wall connector includes an L-shaped plate 1 integrally formed from a horizontal portion 11 and a vertical portion 12, and further includes: a snap-on plate 2, which includes a wall panel 21 and N-shaped snap-on groove plates 22 and a lower hem portion 27 connected to both ends of the wall panel 21. The N-shaped snap-on groove plates 22 have slots 23, and the snap-on plate 2 is connected to the vertical portion 12 of the L-shaped plate 1 through the slots 23. The lower hem portion 27 abuts against the outer surface of the vertical portion 12 to enhance stability; and a ratchet assembly 31, which is disposed on the snap-on plate 2 and has a gear 315 connected to it. A toothed assembly 33 and a limiting plate 34 are respectively provided on one side of the vertical part 12 of the L-shaped plate 1. When the buckle plate 2 moves from one side of the L-shaped plate 1 to the other side, the gear 315 meshes with the toothed assembly 33 and rotates. When the gear 315 reaches the limiting plate 34, the movement of the buckle plate 2 stops, and the buckle plate 2 is locked by the ratchet assembly 31. The fixing bolt 4 and nut 41 are used to connect the L-shaped plate 1. The anti-loosening component is provided on the buckle plate 2 and is used to lock the nut 41 after the ratchet assembly 31 locks the buckle plate 2 on the L-shaped plate 1.

[0032] When this device is in use, the horizontal part 11 has a hole. By using the fixing bolt 4 to pass through the horizontal part 11 on the L-shaped plate 1, the L-shaped plate 1 is connected to the plate on the building wall.

[0033] The buckle plate 2 is connected to one side of the curtain wall panel with bolts, and then the bolts on the curtain wall panel are passed through the wall panel 21 and connected to the wall panel 21, so that the buckle plate 2 is installed on the curtain wall panel.

[0034] During installation, the latch 23 on the snap-on plate 2 is aligned with the vertical part 12, and the latch 23 is positioned on the vertical part 12 from top to bottom. The curtain wall panel is then mounted using the N-type snap-on plate 22. Before aligning the snap-on plate 2 with the vertical part 12, the snap-on plate 2 is positioned to the left of the installer, that is, to the left of the L-shaped plate 1. After mounting the snap-on plate 2 on the L-shaped plate 1, the curtain wall panel, along with the snap-on plate 2, is pushed to the right, that is, towards the toothed assembly 33 and the limiting plate 34 on the L-shaped plate 1. During the process of pushing the curtain wall panel, the ratchet assembly 31 on the snap-on plate 2... Gear 315 first meshes with toothed assembly 33 set on L-shaped plate 1. Since toothed assembly 33 is fixedly connected to L-shaped plate 1, gear 315 will rotate when meshing with toothed assembly 33, so that buckle plate 2 can be pushed normally on L-shaped plate 1. When gear 315 moves to limit plate 34, it is blocked by limit plate 34 and buckle plate 2 can no longer be pushed to move on L-shaped plate 1. At this time, after stopping pushing buckle plate 2, the position of buckle plate 2 on L-shaped plate 1 is locked and fixed. At this time, the curtain wall panel will no longer shift in the left and right directions.

[0035] Therefore, when installing the curtain wall panel, this device only needs to push the curtain wall panel to move, and use the limiting plate 34 to limit the movement of the buckle plate 2, so that the curtain wall panel is locked in a uniform position. This prevents the side of the curtain wall panel from being misaligned when the curtain wall panel is installed in a row. Furthermore, through the ratchet assembly 31, after the gear 315 on the buckle plate 2 reaches the limiting plate 34, the ratchet assembly 31 prevents the buckle plate 2 from moving in the opposite direction, thereby locking the curtain wall panel and preventing displacement in the left and right directions after the curtain wall panel is installed.

[0036] Furthermore, when this device is in use, the anti-loosening component set on the buckle plate 2 can work in conjunction with the movement of the buckle plate 2 on the L-shaped plate 1 to lock and limit the nuts 41 on the fixing bolts 4 on the L-shaped plate 1, which can effectively prevent the nuts 41 from loosening and avoid loosening between the L-shaped plate 1 and the building wall.

[0037] Reference Figure 2 , Figure 4 , Figure 7 , Figure 8 The ratchet assembly 31 includes an outer ratchet disc 311, an inner ratchet disc 312, ratchet teeth 314, and a connecting shaft 313. The ratchet teeth 314 are rotatably connected to the inner ratchet disc 312 via a torsion spring. The torsion spring is mainly used for the reset of the ratchet teeth 314. The ratchet teeth 314 mesh with the ratchet teeth in the outer ratchet disc 311. The connecting shaft 313 is fixedly connected to the inner ratchet disc 312. The inner ratchet disc 312 is rotatably disposed in the outer ratchet disc 311. A connecting plate 3 is installed on the buckle plate 2. The outer ratchet disc 311 is installed on the connecting plate 3 by screws. The gear 315 is fixedly connected to the connecting shaft 313.

[0038] When the buckle plate 2 is aligned with the vertical part 12 and the buckle plate 2 is mounted on the vertical part 12 with the left side of the L-shaped plate 1, when the buckle plate 2 is pushed to move to the right side of the L-shaped plate 1 (the left and right directions are described based on the direction of the installer facing the L-shaped plate 1), the gear 315 rotates when it meshes with the tooth assembly 33. The gear 315 drives the inner ratchet disc 312 to rotate in the outer ratchet disc 311 through the connecting shaft 313.

[0039] When gear 315 rotates while meshing with tooth assembly 33, Figure 7 For example, from a perspective ( Figure 7 (Top view of ratchet assembly 31) The ratchet inner disc 312 rotates clockwise, which allows the buckle plate 2 to move normally to the right on the L-shaped plate 1. When the gear 315 moves to the limit plate 34, the buckle plate 2 can no longer move. At this time, under the action of the ratchet 314, the gear 315 cannot rotate counterclockwise, and the buckle plate 2 cannot move in the opposite direction, thereby achieving the locking of the buckle plate 2.

[0040] Reference Figure 2 It also includes a mounting plate 32 installed on one side of the vertical part 12 of the L-shaped plate 1, and the tooth assembly 33 and the limiting plate 34 are both installed on the mounting plate 32;

[0041] By integrating the tooth assembly 33 and the limiting plate 34 onto the mounting plate 32, it is possible to facilitate quick and uniform installation.

[0042] Example 2, refer to Figure 2 , Figure 5 The process is basically the same as in Embodiment 1, but further: the anti-loosening component includes a rubber wheel 316 fixedly connected to the connecting shaft 313. Multiple protrusions 317 are fixedly connected to the outer circumference of the rubber wheel 316. A groove 42 is provided on the outer circumference of the nut 41, and the protrusions 317 correspond to the groove 42.

[0043] When gear 315 rotates, it will drive rubber wheel 316 to rotate together. When gear 315 comes into contact with limit plate 34, the protrusion 317 on rubber wheel 316 will be located in groove 42 on the outer periphery of nut 41. At this time, protrusion 317 can lock nut 41 and prevent nut 41 from rotating and loosening.

[0044] Furthermore, by rotating the rubber wheel 316, the protrusion 317 on the rubber wheel 316 is allowed to enter the groove 42. This prevents the protrusion 317 from being squeezed hard against the nut 41, which could cause the protrusion 317 to twist, resulting in surface damage or cracking. By rotating the protrusion 317 into the groove 42, the nut 41 can be prevented from squeezing the protrusion 317, thereby releasing the stress on the protrusion 317 and allowing it to be in a relaxed state in the groove 42. This also locks the nut 41 to prevent loosening.

[0045] Example 3, referring to Figure 6 The process is basically the same as in Embodiment 1, but further: the anti-loosening component includes a rubber wheel 316 fixedly connected to the connecting shaft 313, a plurality of protrusions 317 fixedly connected to the outer circumference of the rubber wheel 316, and an external tooth 43 fixedly connected to the outer circumference of the nut 41, the external tooth 43 corresponding to the protrusions 317 on the outer circumference of the rubber wheel 316.

[0046] By offsetting the external teeth 43 on the nut 41 towards the opposite side of the moving direction of the snap plate 2 when installing the fixing bolt 4, that is, on the left side when the installer is facing the L-shaped plate 1, when the snap plate 2 is locked on the L-shaped plate 1, when the nut 41 loosens and rotates counterclockwise (towards... Figure 6 (Taking a perspective example), the external teeth 43 on the nut 41 will contact the protrusion 317 on the rubber wheel 316 and be blocked by the protrusion 317 so that it cannot rotate. Therefore, after the buckle plate 2 is installed, the nut 41 can be locked to prevent loosening.

[0047] Example 4, refer to Figure 4 An adjusting bolt 26 is threaded onto the N-type groove plate 22;

[0048] By rotating the adjusting bolt 26, the distance between the buckle plate 2 and the L-shaped plate 1 can be easily adjusted, thereby facilitating the adjustment of the gap size between adjacent curtain wall panels;

[0049] Meanwhile, when it is necessary to separate the buckle plate 2 from the L-shaped plate 1, the buckle plate 2 can be moved up a greater distance by rotating the adjusting bolt 26, which can separate the gear 315 from the tooth assembly 33, thereby releasing the buckle plate 2 from the locking state on the L-shaped plate 1.

[0050] Reference Figure 4 The inner wall of the N-type groove plate 22 is provided with a first mounting groove 24, and a rubber pad 25 is installed in the first mounting groove 24 to fill the gap between the N-type groove plate 22 and the vertical part 12.

[0051] A second mounting groove 28 is provided on the lower part 27, and the rubber pad 25 is located in the second mounting groove 28;

[0052] By providing rubber pads 25 in the first mounting groove 24 and the second mounting groove 28, the gap between the slot 23 and the vertical part 12 can be filled, preventing the buckle plate 2 from shaking on the L-shaped plate 1.

[0053] Anti-slip stripes 13 are provided on the horizontal part 11 surface of L-shaped plate 1 and the inner side wall of wall panel 21 to improve friction.

[0054] This invention, during the installation of curtain wall panels, only requires pushing the curtain wall panels to move, and uses the limiting plate 34 to restrict the movement of the buckle plate 2, so that the curtain wall panels are locked in a uniform position. This prevents the sides of the curtain wall panels from being misaligned when they are installed in a row. Furthermore, the ratchet assembly 31 prevents the buckle plate 2 from moving in the opposite direction after the gear 315 on the buckle plate 2 reaches the limiting plate 34, thus locking the curtain wall panel and preventing lateral displacement after installation. In addition, the anti-loosening component on the buckle plate 2 works in conjunction with the movement of the buckle plate 2 on the L-shaped plate 1 to lock and limit the nuts 41 on the fixing bolts 4 on the L-shaped plate 1, effectively preventing the nuts 41 from loosening and avoiding loosening between the L-shaped plate 1 and the building wall.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
