Description

Technical Field

[0001] The utility model relates to the field of rotational connection of opening sashes, in particular to a self-locking glass curtain wall opening sash. Background Art

[0002] The opening sash is a window that can be rotatably opened and is rotatably connected to the curtain wall steel beam, and a rotating part connected between the curtain wall steel beam and the window.

[0003] In the prior art, the rotating parts of the opening sash are divided into fixed hangers connected to the curtain wall steel beam and fixed hangers connected to the window body. After the fixed hangers are installed, the plug-in shaft is inserted to make the fixed hangers rotate and connect. Finally, an "L"-shaped blocking member is fixed on the window body to limit the two ends of the plug-in shaft to prevent the plug-in shaft from being separated from the fixed parts.

[0004] The above method is relatively inconvenient during the plug-in shaft connection process, and the blocking member is prone to loosening during long-term use, and it is not easy to find, which poses a high risk during long-term use. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 3In the embodiment of the utility model, a self-locking glass curtain wall opening fan comprises a No. 2 fixed hanger 2 fixedly connected to the curtain wall horizontal steel beam and a No. 1 fixed hanger 1 fixedly connected to the top cross beam of the curtain wall window body, the center space of the No. 1 fixed hanger 1 and the No. 2 fixed hanger 2 is plugged with a plug-in shaft 3, and the interior of the plug-in shaft 3 is provided with two self-locking mechanisms that penetrate to the outside of the plug-in shaft 3; the self-locking mechanism in the pop-up state is used to limit and lock the position of the plug-in shaft 3; the self-locking mechanism comprises two sliding grooves 7 symmetrically opened inside the plug-in shaft 3, the inner wall of the sliding groove 7 is slidably connected with a pop-up member 4, the top surface of the pop-up member 4 is formed with an extrusion slope 5, the bottom end of the extrusion slope 5 is integrally formed with an anti-slip plate 6, and a spring 8 is fixedly connected between the bottom end of the anti-slip plate 6 and the bottom end of the inner wall of the sliding groove 7.

[0021] In this embodiment: first, bolts are used to fix the No. 1 fixing hanger 1 and the No. 2 fixing hanger 2 to the curtain wall cross steel beam and the top cross beam of the curtain wall window respectively. After the connection is completed, the No. 1 fixing hanger 1 is connected to the No. 2 fixing hanger 2. At this time, one No. 1 fixing hanger 1 is located on the inner side of the two No. 2 fixing hangers 2. Then, the plug-in shaft 3 is inserted from the circular holes of the No. 1 fixing hanger 1 and the No. 2 fixing hanger 2. With the insertion of the plug-in shaft 3, the plug-in shaft 3 drives a self-locking mechanism to be squeezed with the inner diameter edge of the circular hole. At this time, the extrusion inclined surface 5 of the self-locking mechanism is squeezed with the inner diameter of the circular hole. The stressed extrusion inclined surface 5 pushes the pop-up member 4 to move downward along the sliding groove 7, and the pop-up member 4 The anti-slip plate 6 is driven to slide downward synchronously. During this process, the spring 8 is compressed until the pop-up piece 4 completely enters the interior of the sliding groove 7. As the plug-in shaft 3 is continuously inserted, the plug-in shaft 3 drives the pop-up piece 4 to move out of the circular hole. At this time, the pop-up piece 4 is popped out under the reset of the spring 8. At the same time, the vertical plane of another pop-up piece 4 is against the end plane of the No. 2 fixed hanger 2. At this time, the two pop-up pieces 4 are respectively located at one end surface of the two No. 2 fixed hangers 2 away from each other. At this time, the position of the plug-in shaft 3 is limited and locked. This method does not need to add an "L"-shaped blocking piece to block the end of the plug-in shaft 3, and has a more convenient installation effect, and will not cause safety risks due to the loosening of the blocking piece.

[0022] Please refer to Figure 3 The vertical section of the sliding groove 7 is a "convex" structure, the outer wall of the anti-drop plate 6 coincides with the inner wall of the non-open end of the sliding groove 7, and the outer wall of the pop-up member 4 coincides with the inner wall of the open end of the sliding groove 7.

[0023] In this embodiment: during the movement of the pop-up member 4, the pop-up member 4 drives the anti-slip plate 6 to move along the wide inner wall of the sliding groove 7, and the inner wall of the open end of the sliding groove 7 serves as the narrow inner wall, which can limit the anti-slip plate 6 to slide only on the wide inner wall of the sliding groove 7, thereby preventing the anti-slip plate 6 from sliding out of the sliding groove 7.

[0024] Please refer to Figure 3 The edges at both ends of the extrusion slope 5 are in an arc state, and the diameter of the arc of the edges at both ends of the extrusion slope 5 is equal to the outer diameter of the plug-in shaft 3.

[0025] In this embodiment: when the extrusion bevel 5 contacts the inner wall of the circular hole, the low point edge of the extrusion bevel 5 is subjected to force, which can drive the pop-up member 4 to move. Since the diameters of the two end edges of the extrusion bevel 5 are equal to the diameter of the circular hole, no movement interference will be caused during the mutual extrusion process.

[0026] Please refer to Figure 3 The end of the extrusion slope 5 close to the second fixed hanger 2 is a high point edge, and the end of the extrusion slope 5 away from the second fixed hanger 2 is a low point edge.

[0027] In this embodiment: during the insertion of the plug-in shaft 3, the low point edge of the extrusion bevel 5 is first squeezed against the inner wall of the circular hole. As the plug-in shaft 3 is pushed in, the contact position of the extrusion bevel 5 and the circular hole coincides with the inner wall of the circular hole, thereby ensuring the smooth pushing of the plug-in shaft 3.

[0028] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
