Description

Technical Field

[0001] This application relates to the field of centering technology, specifically to a centering connection device. Background Technology

[0002] The term "middle brace" refers to the vertical support structure in the middle of a door or window frame, used to enhance stability or divide space.

[0003] A mullion connection device is a special device used in door and window manufacturing to connect mullions (horizontal or vertical support components in door and window frames) to the door and window frame. Its function is to ensure a stable connection between the mullion and the frame, and to improve the overall structural strength and stability of the door and window.

[0004] For example, patent CN221169298U discloses a door and window mullion connecting device. This patent uses an installation mechanism to pull the first pull rod, which moves the moving plate and the locking rod together and squeezes the first spring, causing the T-shaped block to slide into the T-shaped groove. When the first pull rod is released, the moving plate returns to its original position, allowing the locking rod to engage with the groove, thus fixing the connecting parts. The fixing is stable and the operation is convenient.

[0005] In practical use, curtain wall mullions may require regular cleaning or maintenance (such as sealant aging or glass breakage). However, traditional fixed connections require the entire frame to be disassembled, which is time-consuming and labor-intensive, resulting in low efficiency and increased costs.

[0006] Therefore, it is necessary to provide a mid-tumbler connection device to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] like Figure 1 As shown, this application provides a mullion connecting device, which is installed in the middle of a door or window frame for connection and fixation. It is understood that, in situations such as... Figure 1 The window frame 1 shown is hinged to a window sash 2 on one side, and a mullion 3 (i.e., a connecting device) is provided in the middle of the window frame 1. The mullion 3 is designed to prevent the window frame 1 from deforming or breaking.

[0035] like Figures 1-3 As shown, in order to enable quick installation and disassembly of the mullion 3 in different environments, a quick-release mechanism 4 is provided between the mullion 3 and the window frame 1. The quick-release mechanism 4 includes an installation groove 40 located at the upper and lower ends on one side of the window frame 1. A fixing plate 41 is fixedly installed inside the installation groove 40. Multiple sets of positioning posts 42 are fixedly installed on the fixing plate 41. One end of the positioning post 42 is protruding to facilitate positioning during subsequent installation.

[0036] In order to perform preliminary positioning for the installation of the center muzzle 3, a mounting plate 45 is fixedly installed on the upper end of the center muzzle 3. A stabilizing column 49 is fixedly installed on one side of the mounting plate 45. A groove is provided at one end of the stabilizing column 49, which matches the protrusion at one end of the positioning column 42. This allows the positioning column 42 to be inserted into the groove at one end of the stabilizing column 49 during installation, thereby achieving the effect of preliminary positioning.

[0037] In order to perform locking operations after installation, a locking assembly 44 is provided between the fixing plate 41 and the mounting plate 45. The locking assembly 44 includes a locking hole 440 opened on the fixing plate 41, and a stop block 441 is provided at both ends inside the locking hole 440.

[0038] Furthermore, a locking lever 442 is rotatably mounted on the mounting plate 45. One end of the locking lever 442 passes through the mounting plate 45 and is fixedly connected to the control lever 445. Thus, the locking lever 442 can be driven to rotate on the mounting plate 45 by rotating the control lever 445.

[0039] Meanwhile, a locking block 443 is fixedly provided on the outer side of the other end of the locking rod 442. The size of the locking block 443 matches the size of the locking hole 440, so that the locking block 443 can slide along the inside of the locking hole 440 by pushing the locking rod 442.

[0040] When the locking block 443 passes through the locking hole 440 and reaches the other side of the fixing plate 41, the locking rod 442 can be rotated to rotate the locking block 443 to coincide with the stop block 441 inside the locking hole 440. At this time, the position of the locking rod 442 can be locked by the stop block 441.

[0041] It should be noted that when the card block 443 passes through the card hole 440 and reaches the other side of the fixing plate 41, the protrusion of the positioning post 42 will be inserted into the groove of the stabilizing post 49, thereby limiting the position of the mounting plate 45 so that it can be locked and installed stably in the future.

[0042] Furthermore, a positioning hole 448 is provided on the other side of the mounting plate 45, and a positioning pin 449 is threaded on the control rod 445. The size of the positioning pin 449 matches the size of the positioning hole 448. Thus, when the control rod 445 is rotated to drive the locking rod 442 to rotate to the appropriate position, the positioning pin 449 can be rotated into the positioning hole 448 to lock the locking rod 442.

[0043] Finally, rotate the positioning pin 449 into the positioning hole 448 to complete the final locking operation, thereby achieving the purpose of quick installation;

[0044] When disassembly is required, simply rotate the positioning pin 449 away from the positioning hole 448, and then rotate the locking rod 442 to rotate the block 443 to the position of the slide groove 447 to unlock it, thereby achieving the purpose of quick disassembly.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
