Description

Technical Field

[0001] This utility model belongs to the field of building curtain wall technology, and in particular relates to a quick disassembly and assembly connection mechanism and a modular curtain wall. Background Technology

[0002] In the field of building curtain walls, traditional curtain wall systems mostly adopt integral or simple modular structures. Integral curtain walls require prefabrication of complete units in the factory, occupying a large space and being easily damaged during transportation. On-site installation requires large hoisting equipment, resulting in long construction cycles and high costs. While modular curtain walls can achieve modular installation, existing technologies generally suffer from complex connection structures. In the actual assembly process of modular curtain walls on the market, the combination of the frame structure often requires the use of multiple independent connectors. This not only increases the assembly steps but also makes the overall stability of the frame susceptible to insufficient due to mismatch in connector fitting. The connection between the curtain wall body and the frame mostly uses bolt fixing or complex snap-fit ​​structures, requiring repeated adjustments to the alignment position during installation, which is cumbersome. Subsequent maintenance and disassembly also require special tools, which is time-consuming and labor-intensive. At the same time, the reliability of the locking structure after the curtain wall body is installed is poor. Some locking methods can only achieve unidirectional limitation, and they are susceptible to loosening under external forces during long-term use, thus affecting the overall safety of the curtain wall. The treatment of gaps between adjacent curtain wall structures usually relies on filling sealant on-site or installing independent cover plates. The sealant takes a certain amount of time to cure, which prolongs the construction period, and it is prone to aging and falling off when exposed to the outdoor environment for a long time, causing the gaps to reappear. Independent cover plates require additional drilling for fixation, which not only damages the integrity of the curtain wall surface, but may also fall off due to insecure fixation, affecting the consistency of the curtain wall's appearance and its sealing performance. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-assembly and disassembly connection mechanism and a modular curtain wall. In this utility model, the modular curtain wall structure adopts a cross-shaped frame to enhance the overall load-bearing capacity, and achieves rapid and accurate positioning of the curtain wall through sliding adjustment and double limiting structure; the eccentric locking device is easy to operate and reliable in locking, and can be disassembled and assembled without tools; the elastic baffle adapts to deformation, effectively covers gaps, maintains a consistent appearance, significantly improves installation efficiency and long-term stability, and solves the existing technical problems.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A quick-assembly and disassembly connection mechanism for modular curtain walls includes: The main mounting frame has side mounting frames fixedly connected to both sides, and the main mounting frame and the two side mounting frames together form a cross-shaped frame. Multiple curtain wall main bodies are respectively adjacent to the four right-angled sides of the cross-shaped frame; The connecting component includes a T-shaped bracket fixed to the side mounting frame, with support rods at both ends of the T-shaped bracket, and a sliding groove on the side of the curtain wall body near the side mounting frame, the sliding groove being slidably engaged with the support rods; The locking assembly includes a mounting bracket and a fixing rod mounted thereon. A rotary switch is rotatably mounted on the fixing rod. The rotary switch includes a locking wheel with an eccentric hole and a lever. A locking plate is fixed on the curtain wall body. A locking groove is formed on the locking plate. After the locking wheel rotates, its eccentric part engages with the locking groove to achieve locking.

[0005] Optionally, the connecting assembly further includes a connecting bracket fixed to the main mounting frame. The connecting bracket has protrusions on both sides. The curtain wall body has a first abutting protrusion and a second abutting protrusion on the side near the connecting bracket. The second abutting protrusion abuts against the end of the connecting bracket, and the first abutting protrusion engages with the protrusion.

[0006] Optionally, the main mounting frame has a first mounting groove on the side near the curtain wall body, in which a first abutment plate is engaged; the side mounting frame has a second mounting groove on the side near the curtain wall body, in which a second abutment plate is engaged; the first abutment plate and the second abutment plate abut against the curtain wall body.

[0007] Optionally, it also includes a U-shaped elastic plate, the bent end of which is disposed in the mounting groove of the connecting bracket and is fixed by the engagement of the positioning protrusion with the positioning groove in the mounting groove; the movable end of the U-shaped elastic plate is provided with a first end cap, which is located between two adjacent curtain wall bodies.

[0008] Optionally, a second end cap is provided on one side of the side mounting frame. The second end cap has a movable snap-fit ​​end, which is engaged and fixed with the adjacent curtain wall body.

[0009] Optionally, the locking wheel has semicircular rings at both ends and a limiting groove on the locking plate. When the locking wheel rotates to the locking position, the semicircular rings are engaged in the limiting groove to achieve vertical limiting.

[0010] Optionally, the rotary switch is equipped with a damping bearing inside, which allows it to rotate damped on the fixed rod.

[0011] Optionally, the first abutment plate and the second abutment plate have a serrated anti-slip surface on the side that abuts against the curtain wall body.

[0012] A modular curtain wall includes the quick-assembly and disassembly connection mechanism described in any one of the above.

[0013] The embodiments of this utility model have the following beneficial effects: In this utility model, the main mounting frame is fixedly connected to the side mounting frames on both sides to form a cross-shaped frame. The structural characteristics of the cross-shaped frame can provide stable support for the curtain wall body in four directions and improve the overall load-bearing capacity of the frame. In this invention, a sliding groove is provided on one side of the curtain wall body near the mounting frame, which engages with the support rod at the adjacent end of the T-shaped bracket to complete the sliding adjustment, thus quickly completing the initial positioning of the curtain wall body and reducing the alignment adjustment time during installation; the protrusions on both sides of the connecting bracket engage with the first abutting protrusion of the curtain wall body, and the second abutting protrusion abuts with the end of the connecting bracket, thus limiting the curtain wall body in both the horizontal and vertical directions, preventing the curtain wall body from shifting during installation and improving the connection accuracy; In this invention, the locking wheel in the locking assembly is rotatably sleeved on the outer wall of the fixing rod through an eccentric hole off-center. With the help of the damping bearing, the operator can drive the locking wheel to rotate stably by turning the lever. Its eccentric protrusion can quickly engage with the locking groove of the curtain wall main body locking plate to lock the curtain wall main body in the direction of the support rod. At the same time, the semi-circular rings at both ends of the locking wheel can engage with the limiting groove of the locking plate after the locking wheel rotates into place, further limiting the vertical direction of the curtain wall main body. The double limiting ensures the reliable locking of the curtain wall main body and avoids loosening during long-term use. Moreover, locking and unlocking can be completed by turning the lever without special tools, which significantly improves the efficiency of disassembly and assembly and facilitates subsequent maintenance. In this invention, the bent end of the U-shaped elastic plate is placed in the mounting groove of the connecting bracket and fixed by the engagement of the positioning protrusion with the positioning groove. The first end cap of its movable end can directly cover the gap between adjacent curtain wall bodies. The second end cap is fixed to the adjacent curtain wall body by the movable snap-fit ​​end, filling the gap in the horizontal direction. There is no need to apply sealant on site or drill additional holes for fixation, which simplifies the gap treatment steps. Moreover, the elasticity of the U-shaped elastic plate and the movable snap-fit ​​end of the second end cap can adapt to the slight deformation of the curtain wall body caused by temperature changes, avoiding gaps in the end cap due to deformation, maintaining the blocking effect for a long time, and ensuring the consistency of the curtain wall appearance. In this utility model, the first abutting plate and the second abutting plate are provided with a serrated anti-slip surface on the side of the curtain wall body. When they abut against the curtain wall body, the friction of the contact surface can be increased, which can prevent the curtain wall body from shifting during the sliding installation process, improve the continuous stability during and after installation, and further ensure the installation accuracy.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] In one embodiment: Please refer to Figure 1-9 As shown, this embodiment provides a curtain wall and its connection structure. The modular curtain wall includes a main mounting frame 2, two side mounting frames 3, multiple curtain wall bodies 1, and connecting components.

[0022] In this embodiment, the main mounting frame 2 is fixed with side mounting frames 3 by bolts on both sides. The main mounting frame 2 and the two side mounting frames 3 are combined to form a cross-shaped frame. The four right-angled sides of the cross-shaped frame correspond to the installation positions of the respective curtain wall main body 1.

[0023] In this embodiment, the connecting assembly includes a T-shaped bracket 14 and a connecting bracket 6. The T-shaped bracket 14 is fixed to the side of the side mounting frame 3 away from the main mounting frame 2 by bolts, and its two ends of the T-shape extend vertically, with a support rod 15 welded to each end. A groove 16 is provided on the side of the curtain wall body 1 near the side mounting frame 3. The cross-sectional shape of the groove 16 matches the cross-sectional shape of the support rod 15. The support rod 15 can be inserted into the groove 16 by interference fit, and finally slide along the groove 16 to complete the initial connection between the curtain wall body 1 and the side mounting frame 3.

[0024] In this embodiment, the connecting bracket 6 is fixed to the side of the main mounting frame 2 away from the side mounting frame 3 by bolts, and protrusions 7 are welded on both sides of it. The curtain wall body 1 has a first abutting protrusion 21 and a second abutting protrusion 22 integrally formed on the side near the connecting bracket 6, wherein the second abutting protrusion 22 abuts against the end of the connecting bracket 6, and the first abutting protrusion 21 abuts against and engages with the protrusions 7 on the side of the connecting bracket 6. The position of the curtain wall body 1 is further fixed by the limiting effect of the protrusions 7 on the first abutting protrusion 21.

[0025] In this embodiment, a U-shaped elastic plate 9 is provided on the side of the main mounting frame 2 away from the curtain wall body 1. The bent end of the U-shaped elastic plate 9 is inserted into the mounting groove opened on the connecting bracket 6. Positioning protrusions 11 are integrally formed on both outer walls of the U-shaped elastic plate 9. Positioning grooves 8 are correspondingly opened on the inner wall of the mounting groove of the connecting bracket 6. The positioning protrusions 11 and the positioning grooves 8 are engaged to realize the installation and positioning of the U-shaped elastic plate 9. The two movable ends of the U-shaped elastic plate 9 extend to the outside of the connecting bracket 6 and are respectively fixed with first end caps 10. After the two first end caps 10 are engaged, they are located in the gap between two adjacent curtain wall bodies 1 to fill and cover the gap.

[0026] In this embodiment, a second end cap 17 is provided on the side of the side mounting frame 3 away from the main mounting frame 2. One end of the second end cap 17 is formed into two movable snap-fit ​​ends by injection molding. The two movable snap-fit ​​ends are elastic and can be respectively snapped into the slots on the side of the adjacent two curtain wall bodies 1 that are close to each other. The second end cap 17 is fixed by interference fit. At the same time, the main body of the second end cap 17 fills and covers another gap between the curtain wall bodies 1.

[0027] In this embodiment, the quick-assembly and disassembly connection mechanism includes the aforementioned modular curtain wall, two mounting brackets 18, and four sets of locking components. The two mounting brackets 18 are fixed to both sides of the main mounting frame 2 by bolts, and the two mounting brackets 18 on the same side are located on the upper and lower sides of the mounting frame 3 on that side, respectively.

[0028] In this embodiment, each locking assembly includes a fixed rod 19 and a rotary switch 20. The fixed rod 19 is vertically fixed to the mounting bracket 18 near the curtain wall body 1 by bolts. The rotary switch 20 consists of a locking wheel 26 and a lever. The locking wheel 26 has an eccentric hole 27 off-center, and the locking wheel 26 is sleeved around the fixed rod 19 through the eccentric hole 27, allowing it to rotate around the fixed rod 19. The lever is welded to the outer edge of the locking wheel 26 and is used to manually rotate the locking wheel 26.

[0029] Furthermore, in this embodiment, a locking plate 23 is welded to the side of the curtain wall body 1 near the mounting bracket 18, and a locking groove 24 is formed on the side of the locking plate 23 facing the mounting bracket 18. When it is necessary to lock the curtain wall body 1, the lever is rotated to make the locking wheel 26 rotate around the fixing rod 19. The outer edge of the locking wheel 26 gradually enters the locking groove 24. Through the eccentric structure of the eccentric hole 27 and the fixing rod 19, the outer edge of the locking wheel 26 abuts tightly against the inner wall of the locking groove 24, thereby restricting the movement of the curtain wall body 1 in the direction perpendicular to the mounting bracket 18.

[0030] In this embodiment, the two ends of the locking wheel 26 are formed with semi-circular rings 28 by injection molding, and the locking plate 23 has a corresponding limiting groove 25 on the side facing the locking wheel 26. When the locking wheel 26 rotates to the locked position, the semi-circular rings 28 are precisely engaged in the limiting grooves 25. Through the cooperation between the semi-circular rings 28 and the limiting grooves 25, the movement of the curtain wall body 1 in the vertical direction can be restricted, so as to achieve stable installation of multiple curtain wall bodies 1.

[0031] This application can be used in the field of building curtain wall technology, or in other fields applicable to this application.

[0032] In another embodiment: Reference Figure 3 , 4 5, 6, 8, A quick-assembly and disassembly connection mechanism and modular curtain wall, which are applied to the field of building curtain wall technology; In this embodiment, the main mounting frame 2 has two first mounting slots 4 on the side near the curtain wall body 1. Each first mounting slot 4 has a first abutment plate 5 engaged within it. The first abutment plate 5 is elastically fitted with the inner wall of the first mounting slot 4, and its outer surface abuts against the side of the curtain wall body 1. The side mounting frame 3 has two second mounting slots 12 on the side near the curtain wall body 1. Each second mounting slot 12 has a second abutment plate 13 engaged within it. The second abutment plate 13 is also elastically fitted and fixed, and its outer surface abuts against the side of the curtain wall body 1. The first abutment plate 5 and the second abutment plate 13 together provide lateral support and positioning for the curtain wall body 1.

[0033] In this embodiment, after the multiple rotary switches 20 are closed, their dials should face the side closer to the main mounting frame 2 to ensure that the rotary switches 20 will not be accidentally turned on when the curtain wall body 1 tends to detach outward.

[0034] In this embodiment, each of the multiple rotary switches 20 is equipped with a damping bearing to ensure that the multiple rotary switches 20 can complete damped rotation on the corresponding fixed rod, thereby improving the switching stability of the rotary switches 20.

[0035] The usage process and working principle of this utility model technical solution are as follows: The installation process of the modular curtain wall begins with the assembly of the main mounting frame 2 and the side mounting frames 3. The side mounting frames 3 are fixedly connected to both sides of the main mounting frame 2, forming a cross-shaped frame structure. Multiple curtain wall bodies 1 are installed corresponding to the four right-angled sides of the cross-shaped frame.

[0036] When installing the curtain wall body 1, first mate the side of the curtain wall body 1 closest to the side mounting frame 3 with the T-shaped bracket 14. The T-shaped bracket 14 is fixed to one side of the side mounting frame 3, and each end of its T-shape is equipped with a support rod 15. The curtain wall body 1 can be engaged with the outer wall of the adjacent support rod 15 through the sliding groove 16 opened on the curtain wall body 1. Then, the curtain wall body 1 can be further slidably adjusted. The support rod 15 can provide installation support for the curtain wall body 1 to achieve its initial installation positioning.

[0037] After the curtain wall body 1 is slidably installed into place, the first abutting protrusion 21 and the second abutting protrusion 22 on one side can abut against one side of the adjacent connecting bracket 6. Among them, the first abutting protrusion 21 abuts against the protrusion 7 fixedly installed on the side wall of the connecting bracket 6, and the second abutting protrusion 22 abuts against one end of the connecting bracket 6, thereby completing the further positioning of the curtain wall body 1.

[0038] After the curtain wall body 1 is slidably installed into place, the locking plate 23 installed on one side corresponds to the multiple adjacent rotary switches 20. At this time, the operator only needs to turn the multiple rotary switches 20 in sequence. Since the locking wheels 26 inside the multiple rotary switches 20 are all eccentrically set, when they rotate, their eccentric protrusions will abut and engage with the locking grooves 24 opened on one side of the adjacent locking plates 23, which can lock the curtain wall body 1 on the support rod 15. At the same time, after the rotary switches 20 are closed, the semi-circular rings 28 at both ends of the locking wheels 26 can engage with the limiting grooves 25 on the locking plates 23, thereby further limiting the curtain wall body 1 in the vertical direction. This structure ensures the rapid installation and disassembly of the curtain wall body 1, and is simple, stable and reliable in operation.

[0039] After the curtain wall body 1 is installed, one side of it will abut against the corresponding first abutment plate 5 and second abutment plate 13. The first abutment plate 5 and the second abutment plate 13 are provided with serrated anti-slip surfaces on the side close to the curtain wall body 1, which abut against the curtain wall body 1 to improve the stability of the curtain wall body 1 during sliding installation.

[0040] After the installation and fixing of multiple adjacent curtain wall main bodies 1 are completed, the operator can place the bent end of the corresponding U-shaped elastic plate 9 into the installation groove at one end of the connecting bracket 6. The U-shaped elastic plate 9 can be positioned and installed by its own elasticity and the cooperation of the corresponding positioning protrusion 11 and the internal positioning groove 8 of the connecting bracket 6. At this time, the two first end caps 10 installed on the movable end of the U-shaped elastic plate 9 can cover the gap between the corresponding curtain wall main bodies 1. At the same time, by using the two horizontally set second end caps 17, its movable snap-fit ​​end is snapped and fixed with the adjacent curtain wall main body 1, which can fill and cover the gap in the horizontal direction to ensure a better overall aesthetic appearance of the curtain wall.
