Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, in particular to an inward-opening and inward-tilting hinge device. Background Art

[0002] A tilt-and-turn hinge is a hardware accessory for windows. It allows the window to open inward, meeting daily ventilation needs and emergency escape requirements, or tilt inward at a certain angle. In this tilted position, the window allows for micro-ventilation, ensuring indoor air circulation while preventing strong winds and rain from entering directly. While existing tilt-and-turn hinges are convenient and facilitate ventilation, they have drawbacks in terms of load-bearing capacity and sealing, as follows:

[0003] Load-bearing

[0004] When bearing weight, inward-opening and tilting hinges must not only bear the weight of the window itself, but also the additional torque that may be generated when the window is tilted. At the same time, the load-bearing capacity of inward-opening and tilting hinges is relatively limited. For windows of larger sizes or heavier materials, they cannot provide sufficient support. Long-term use may cause problems such as hinge loosening and deformation.

[0005] Sealing

[0006] The structure of the inward-opening and inward-tilting hinge is complex and the sealing reliability is not high; the inward-opening and inward-tilting hinge is affected by the use environment and is prone to air leakage and water leakage.

[0007] In summary, there is an urgent need for an inward-opening and inward-tilting hinge with good load-bearing capacity and high sealing performance. Utility Model Content

[0008] In order to solve the above problems, especially to address the deficiencies in the prior art, the present invention provides an inward-opening and inward-tilting hinge device that can solve the above problems.

[0009] In order to achieve the above purpose, the utility model adopts the following technical means:

[0010] An inward-opening and inward-inverting hinge device includes a bending base plate, which is rotatably connected to a diagonal rod strip through a first rotating connecting piece, the middle of the first rotating connecting piece is rotatably connected to a second rotating connecting piece, one end of the second rotating connecting piece is slidably connected to the bending base plate, and the other end of the second rotating connecting piece is rotatably connected to the diagonal rod strip through a third rotating connecting piece, one side of the diagonal rod strip is connected to a diagonal rod cover, a transmission aluminum bar is connected inside the diagonal rod cover, one end of the transmission aluminum bar is connected to a load-bearing back plug through an aluminum bar tail buckle, the end of the load-bearing back plug away from the aluminum bar tail buckle is connected to a plug tip, and the end of the diagonal rod strip close to the bending base plate is connected to a U-shaped bending head corresponding to the plug tip, and the plug tip is movably plugged into the U-shaped bending head.

[0011] A further solution of the present invention is that one end of the bent bottom plate is connected to an anti-pull biasing piece.

[0012] A further solution of the present invention is that the other end of the bent bottom plate is connected to an upper flat plate.

[0013] A further solution of the present invention is that the U-shaped bending head is provided with a square hole groove, the plug tip is a cone-shaped structure, and the plug tip is movably plugged into the square hole groove.

[0014] A further solution of the present invention is that the pointed insert and the load-bearing back insert are made into one piece.

[0015] A further solution of the present invention is that the U-shaped bending head and the diagonal tie rod strip are made into one piece.

[0016] A further solution of the present invention is that the other end of the transmission aluminum bar is connected to an aluminum bar head buckle.

[0017] Beneficial effects of the utility model:

[0018] 1. The load-bearing back insert of the utility model is connected to the window sash as a whole, and the long strip of the inclined rod is connected to the window frame as a whole. The pointed end of the load-bearing back insert can be hung at the U-shaped bending head, thereby realizing the load-bearing function of the window sash and effectively improving the load-bearing capacity of the inward-opening and inward-tilting hinge.

[0019] 2. When the doors and windows are closed, the plug head of the utility model passes through the square hole groove. The plug head is inclined and becomes tighter as it enters the square hole groove. Since the window sash and the plug head are integrated, the window sash can be clamped and the distance between the window frame can be increased, effectively improving the sealing performance of the inward-opening and inward-tilting hinge.

DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention. Example

[0026] like Figures 1 to 3 As shown, an inward-opening and inward-inverting hinge device includes a bending base plate 2, which is rotatably connected to a diagonal rod strip 15 through a first rotating connecting piece 3, and the middle part of the first rotating connecting piece 3 is rotatably connected to a second rotating connecting piece 4, one end of the second rotating connecting piece 4 is slidingly connected to the bending base plate 2, and the other end of the second rotating connecting piece 4 is rotatably connected to the diagonal rod strip 15 through a third rotating connecting piece 10, one side of the diagonal rod strip 15 is connected to a diagonal rod cover 13, and a transmission aluminum bar 12 is connected inside the diagonal rod cover 13, and one end of the transmission aluminum bar 12 is connected to a load-bearing back plug 9 through an aluminum bar tail buckle 11, and the end of the load-bearing back plug 9 away from the aluminum bar tail buckle 11 is connected to a plug tip 8, and the end of the diagonal rod strip 15 close to the bending base plate 2 is connected to a U-shaped bending head 7 corresponding to the plug tip 8, and the plug tip 8 is movably plugged into the U-shaped bending head 7.

[0027] Working principle:

[0028] When the door or window is closed, the handle is rotated 90 degrees downward or upward, driving the transmission aluminum strip 12 to move left or right. The aluminum strip tail buckle 11 connects to the load-bearing back plug 9, allowing the load-bearing back plug 9 to pass through the U-shaped bend 7 at the end of the diagonal rod strip 15. When the handle is open, the tip 8 of the load-bearing back plug 9 can be hooked at the U-shaped bend 7. Because the load-bearing back plug 9 connected to the aluminum strip tail buckle 11 is integrally connected to the window sash, and the diagonal rod strip 15 is integrally connected to the window frame, the tip 8 of the load-bearing back plug 9 is hooked at the U-shaped bend 7, thus achieving the load-bearing function of the window sash.

[0029] The U-shaped bending head 7 is provided with a square hole groove 6, and the plug tip 8 of the load-bearing back plug 9 is inclined. When the plug tip 8 enters the square hole groove 6, it will get tighter and tighter. Since the window sash and the plug tip 8 are integrated, the window sash can be clamped and the distance between the window frame can be adjusted to achieve the sealing effect. Example

[0030] like Figures 1 to 3 As shown, an inward-opening and inward-inverting hinge device includes a bending base plate 2, which is rotatably connected to a diagonal rod strip 15 through a first rotating connecting piece 3, and the middle part of the first rotating connecting piece 3 is rotatably connected to a second rotating connecting piece 4, one end of the second rotating connecting piece 4 is slidingly connected to the bending base plate 2, and the other end of the second rotating connecting piece 4 is rotatably connected to the diagonal rod strip 15 through a third rotating connecting piece 10, one side of the diagonal rod strip 15 is connected to a diagonal rod cover 13, and a transmission aluminum bar 12 is connected inside the diagonal rod cover 13, and one end of the transmission aluminum bar 12 is connected to a load-bearing back plug 9 through an aluminum bar tail buckle 11, and the end of the load-bearing back plug 9 away from the aluminum bar tail buckle 11 is connected to a plug tip 8, and the end of the diagonal rod strip 15 close to the bending base plate 2 is connected to a U-shaped bending head 7 corresponding to the plug tip 8, and the plug tip 8 is movably plugged into the U-shaped bending head 7.

[0031] One end of the bending base plate 2 is connected to an anti-pull biasing piece 1. The anti-pull biasing piece 1 can ensure that the bending base plate 2 is evenly stressed, prevent the bending base plate 2 from deflecting, enhance the connection stability of the bending base plate 2, and reduce friction and wear of the bending base plate 2.

[0032] The other end of the bending base plate 2 is connected with an upper flat plate 5. The upper flat plate 5 can facilitate the bending base plate 2 to be connected to external structural parts, and can effectively improve the working efficiency and effect of the bending base plate 2.

[0033] The U-shaped bending head 7 is provided with a square hole groove 6, and the plug tip 8 is a tapered structure, and the plug tip 8 is movably plugged into the square hole groove 6. The tapered plug tip 8 is inclined, and when the plug tip 8 enters the square hole groove 6, it becomes tighter and tighter, thereby driving the window sash to clamp the distance between the window frame and the window frame, achieving a sealing effect.

[0035] The plug tip 8 and the load-bearing back insert 9 are made in one piece. This arrangement can effectively improve the tightness between the plug tip 8 and the load-bearing back insert 9, and can effectively prevent the plug tip 8 and the load-bearing back insert 9 from breaking.

[0036] The U-shaped bending head 7 is made of an integral body with the diagonal tie rod strip 15. This arrangement can effectively improve the tightness between the U-shaped bending head 7 and the diagonal tie rod strip 15, and can effectively prevent the U-shaped bending head 7 and the diagonal tie rod strip 15 from breaking.

[0037] The other end of the transmission aluminum bar 12 is connected with an aluminum bar head buckle 14.
