[0002] A top hinge is an additional support system installed on the upper part of a hung window or window sash to support and connect the opening and closing movement of the window sash. The hinge is usually made of metal or other strong materials and is installed between the window frame and the window sash, allowing the window sash to rotate along the hinge axis. The top hinge of a hung window allows the window sash to be opened and closed easily and provides additional support and stability. This design is often used for larger or heavier window sashes to ensure the safety and convenience of the window sash.

[0003] When installing the hinge of the existing suspended window, the support arm has a fixed size and cannot adjust the distance from the window sash. In addition, the single support arm connection is not stable enough. Utility Model Content

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: an upper hinge for an outward-opening bottom-hung window, comprising a window frame and a window sash, wherein a connecting component is arranged between the window frame and the window sash.

[0006] The connecting assembly includes a first support arm and a second support arm, one end of the first support arm is installed with an adjustment block through an eccentric locking point, a pad is fixedly installed on the surface of the first support arm, and the surfaces of the pad and the first support arm are both provided with a first slide groove, the surface of the second support arm is provided with a second slide groove, the inner cavities of the first slide groove and the second slide groove are slidably connected with the second connecting member and the first connecting member through a sliding member, and the two ends of the second connecting member and the first connecting member are rotatably connected to the second support arm and the first support arm through a latch, and the middle of the second support arm and the first support arm is rotatably connected through a latch.

[0007] Preferably, a connecting plate is fixedly mounted on the upper end of the second supporting arm, and a first connecting block is fixedly mounted on the surface of the connecting plate.

[0008] Preferably, a second connecting block is fixedly mounted on the lower end of the second supporting arm.

[0009] Preferably, a plurality of holes are formed on the surface of the adjusting block.

[0010] Preferably, the first connecting member and the second connecting member are cross-fitted and connected to each other. Beneficial Effects

[0011] The utility model provides an upper hinge for an outward-opening bottom-hung window. Compared with the prior art, it has the following beneficial effects:

[0012] 1. The upper hinge of the outward-opening bottom-hung window is adjusted by pulling the adjustment block to determine the distance and then fixing the adjustment block to one end of the first bracket through the eccentric locking point, so that the distance connected to the window sash can be adjusted.

[0013] 2. The hinge on the outward-opening bottom-hung window can slide in the inner cavity of the window sash through the second connecting block and the first connecting block, so that the second connecting block, the second supporting arm and the connecting plate and the first connecting block can fit the inner cavity of the window sash more closely. Secondly, the L-shaped connection of the connecting plate increases the strength and stability, making the overall connection more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1 The utility model provides a technical solution: an upper hinge for an outward-opening bottom-hung window, comprising a window frame 1 and a window sash 2, wherein a connecting component 3 is arranged between the window frame 1 and the window sash 2.

[0020] See also Figure 2-3The connecting assembly 3 includes a first supporting arm 31 and a second supporting arm 35. A connecting plate 36 is fixedly installed on the upper end of the second supporting arm 35, and a first connecting block 37 is fixedly installed on the surface of the connecting plate 36. A second connecting block 39 is fixedly installed on the lower end of the second supporting arm 35. An adjusting block 32 is installed on one end of the first supporting arm 31 through an eccentric locking point 312. A plurality of holes are provided on the surface of the adjusting block 32. A pad 33 is fixedly installed on the surface of the first supporting arm 31. The pad 33 can protect the first supporting arm 31 and avoid wear of the first supporting arm 31 caused by sliding.

[0021] A first slide groove 34 is provided on the surface of the pad 33 and the first support arm 31, and a second slide groove 38 is provided on the surface of the second support arm 35. The inner cavities of the first slide groove 34 and the second slide groove 38 are slidably connected with the second connecting member 311 and the first connecting member 310 through a sliding member, wherein the sliding member is composed of a latch and a gasket, and can drive the first connecting member 310 and the second connecting member 311 to slide in the second slide groove 38 and the first slide groove 34, the first connecting member 310 and the second connecting member 311 are cross-fitted and connected to each other, and the two ends of the second connecting member 311 and the first connecting member 310 are rotatably connected to the second support arm 35 and the first support arm 31 through a latch, and the middle of the second support arm 35 and the first support arm 31 is rotatably connected through a latch.

[0022] During operation, firstly, the second connecting block 39, the second supporting arm 35, the connecting plate 36 and the first connecting block 37 are slidably sleeved in the inner cavity of the window frame 1, and the second connecting block 39, the second supporting arm 35, the connecting plate 36 and the first connecting block 37 are fixed by screws, and then the pad 33, the first slide groove 34, the first supporting arm 31 and the adjusting block 32 are slidably sleeved in the inner cavity of the window sash 2, and the first slide groove 34 and the pad 33 are first fixed by screws, wherein the second connecting block 39 and the first connecting block 37 can slide in the inner cavity of the window sash 2, so that the second connecting block 39, the second supporting arm 35, the connecting plate 36 and the first connecting block 37 can fit the inner cavity of the window sash 2 more closely, and secondly, the L-shaped connection of the connecting plate 36 increases the strength and stability, making the overall connection more stable.

[0023] Then, the two ends of the intersection of the first connecting member 310 and the second connecting member 311 are fixedly connected to the second bracket 35 and the first slide groove 34, and the other two ends slide on the first slide groove 34 and the second slide groove 38 through the sliding member.
