[0001] This utility model relates to an inward tilting linkage structure with an upper hinge for an inward opening and tilting window sash, belonging to the technical field of door and window hardware accessories. Background Technology
[0002] The existing inward-opening and tilt-and-turn window sashes require manual pulling to open the tilt-and-turn hinge after the upper hinge is unlocked by turning the handle. Manually pulling the tilt-and-turn hinge is not easy to control and requires high strength of the window sash hardware.
[0003] Therefore, it is necessary to design an inward-opening and inward-tilting window sash with hinges that automatically tilts inward when the window is opened. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing inward-opening and tilt-and-turn window sashes require manual opening of the tilt-and-turn mechanism, and to provide an inward-opening and tilt-and-turn window sash hinge that automatically tilts the window sash inward when it is opened.
[0005] This utility model is achieved through the following technical solution:
[0006] An inward-opening and tilt-and-turn window sash with an inward-tilting linkage structure includes a sash fixing seat and a transmission component slidably connected to the sash fixing seat. The sash fixing seat is provided with an inclined rod connecting an inward-opening linkage component. The inclined rod is slidably and rotatably connected to the sash fixing seat. A rotatable short rod is provided between the sash fixing seat and the inclined rod. A rotatable transmission rod is provided between the short rod and the sash fixing seat. The transmission component slidably connects to the transmission rod and drives it to rotate.
[0007] The inward-opening and tilt-and-turn window sash described above uses an inward-tilting linkage structure with an upper hinge, characterized in that one end of the short rod is rotatably connected to the inclined rod, and the other end of the short rod is slidably and rotatably connected to the sash fixing seat.
[0008] The inward-opening and tilting window sash described above uses an inward-tilting linkage structure with an upper hinge, characterized in that the inclined rod and the short rod are respectively slidably connected to the two ends of the sash fixing seat, and the transmission rod is connected between the connection point of the inclined rod and the short rod.
[0009] The inward-opening and tilt-and-turn window sash described above uses an inward-tilting linkage structure with an upper hinge, characterized in that the diagonal rod and the short rod slide and rotate along the axial direction of the sash fixing seat, respectively.
[0010] The inward-opening and tilting window sash described above uses an inward-tilting linkage structure with an upper hinge, characterized in that the transmission rod is provided with a transmission groove, the sash fixing seat is provided with an axial through groove, and the transmission component is provided with a transmission column that passes through the through groove and extends into the transmission groove. The transmission column moves within the through groove and the transmission groove and drives the transmission rod to rotate.
[0011] The inward-opening and tilting window sash described above uses an inward-tilting linkage structure with a hinge, characterized in that the transmission groove includes different strokes with misaligned shaft centers.
[0012] The inward-opening and tilting window sash described above uses an inward-tilting linkage structure with an upper hinge, characterized in that the transmission groove is a Z-shaped groove, and a portion of the transmission groove is a straight groove arranged along the axial direction of the transmission rod.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] In this invention, the diagonal rod and the short rod are slidably connected to the two ends of the sash fixing seat, and the transmission rod is rotatably connected to the middle of the sash fixing seat. The transmission groove of the transmission rod cooperates with the transmission column. When the transmission component moves axially, the transmission rod rotates, thereby driving the short rod and the diagonal rod to open, realizing the window sash opening inward without external force pulling the window sash, avoiding impact on the profile, improving the durability of the hinge, and ensuring safe use. Attached Figure Description
[0015] Figure 1 This is a three-dimensional structural diagram of the present invention;
[0016] Figure 2 This is an exploded structural diagram of the present invention;
[0017] Figure 3 This is a partial exploded view of the structure of this utility model. Detailed Implementation
[0018] The present invention will be further described in detail below with reference to specific embodiments.
[0019] like Figure 1-3 As shown, an inward-opening and tilt-and-turn window sash with an inward-tilting linkage structure using an upper hinge includes a sash fixing base 1 and a transmission component 2 slidably connected to the sash fixing base 1. The sash fixing base 1 is provided with a diagonal rod 3 connecting to an inward-opening linkage component 6. The diagonal rod 3 is slidably and rotatably connected to the sash fixing base 1. A rotatable short rod 4 is provided between the sash fixing base 1 and the diagonal rod 3. A rotatable transmission rod 5 is provided between the short rod 4 and the sash fixing base 1. The transmission component 2 is slidably and rotatably connected to the transmission rod 5. When the handle is rotated and the transmission component 2 moves, the transmission rod 5 is driven to rotate during the movement of the transmission component 2, thereby driving the short rod 4 and the diagonal rod 3 to open, realizing automatic inward tilting of the window sash without the need for pulling force after unlocking.
[0020] In a preferred embodiment of this invention, one end of the short rod 4 is rotatably connected to the diagonal rod 3, and the other end of the short rod 4 is slidably and rotatably connected to the sash fixing seat 1. The transmission rod 5 is hinged to the middle of the short rod 4. This achieves the shortest stroke for tilting the window sash inward without tilting it too far inward, thus ensuring the safety performance of the window sash. Alternatively, the other end of the short rod 4 can be hinged to the transmission rod 5, and a connecting rod (not shown in the figure) can be rotatably connected to the sash fixing seat 1. The other end of the connecting rod is coaxially hinged to the short rod 4 and the transmission rod 5, which can also achieve automatic inward tilting and opening of the window sash.
[0021] In a further preferred embodiment, the diagonal rod 3 and the short rod 4 are slidably connected to both ends of the sash fixing seat 1, and the transmission rod 5 is connected between the diagonal rod 3 and the short rod 4 and the sash fixing seat 1. This ensures that when the window sash is tilted inward, the sash fixing seat 1 is subjected to uniform force, making it safer.
[0022] To improve the strength of the diagonal rod 3 and the short rod 4, the diagonal rod 3 and the short rod 4 slide and rotate along the axial direction of the fan mounting base 1, respectively. That is, the two ends of the fan mounting base 1 are respectively provided with a diagonal rod groove 12 and a short rod groove 13. The diagonal rod 3 and the short rod 4 are slidably connected to the fan mounting base 1 by connecting pins, avoiding the need for slotting on the diagonal rod 3 and the short rod 4, which would affect their strength. Furthermore, the grooves are only provided on the fan mounting base 1 and the transmission rod 5, reducing the machining difficulty of other parts.
[0023] In a preferred embodiment of the transmission component 2 driving the transmission rod 5 to rotate during its movement, the transmission rod 5 is provided with a transmission groove 51, the fan fixing seat 1 is provided with an axial through groove 11, the transmission component 2 is provided with a transmission column 21 that passes through the through groove 11 and extends into the transmission groove 51, and the transmission column 21 moves within the through groove 11 and the transmission groove 51 and drives the transmission rod 5 to rotate.
[0024] Preferably, the transmission groove 51 includes different strokes with misaligned shafts. For example, the transmission groove 51 is a Z-shaped groove, and a portion of the straight groove of the transmission groove 51 is an axial straight groove, which is the transmission stroke of the inward-opening window sash. When the stroke direction of the transmission groove 51 changes, the transmission stroke of the window sash tilting inward begins. The end of the inward tilting stroke changes direction again, which helps to ensure the stability of the window sash tilting inward.
[0025] In use, the inward opening linkage component 6 connects to the frame fixing seat 7, forming an inward opening and inward tilting window sash hinge together with the inward tilting locking structure 8. When the window sash needs to tilt inward, rotating the handle moves the transmission component 2 away from the frame fixing seat 7. During the movement, the inward tilting locking structure 8 is unlocked. When the transmission column 21 moves in the transmission groove 51, the transmission rod 5 is pushed to rotate, which in turn drives the short rod 4 and the diagonal rod 3 to rotate, opening the inward tilting linkage structure and realizing the inward tilting of the window sash. At the same time, the inward opening linkage component 6 is also partially opened. When the inward tilting window sash needs to be closed, rotating the handle moves the transmission component 2 in the opposite direction, causing the transmission rod 5, the diagonal rod 3 and the short rod 4 to retract and close towards the sash fixing seat 1. At the same time, the inward opening linkage component 6 is also closed, realizing the closure of the inward tilting window sash.
