In addition, the existing upper hinge needs to meet the requirements of casement and inward tilting, and the locking block connection does not support the inward tilting function. Therefore, this technology still has a certain room for modification. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a high load-bearing top suspension hinge in view of the deficiencies of the above-mentioned prior art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a high-load-bearing top-hanging hinge, comprising a base, wherein the base is provided with a mounting plate installed on the window sash through a connecting plate assembly, and is characterized in that a load-bearing member is provided at the bottom end of the mounting plate, and a riveting structure is provided between the load-bearing member and the mounting plate to enable the load-bearing member to be hung on the mounting plate and to enable the window sash to be clamped.
[0006] By adopting the above technical solution, the mounting plate is provided with a load-bearing part through a riveted structure, and the groove of the window sash is inserted into the gap generated by the suspension. The rivet structure has a better load-bearing capacity than the locking block. At the same time, the load-bearing part is suspended on the mounting plate and has a certain range of motion when it is inserted into the window sash.

When the axial frame body of the load-bearing component is inserted into the inner side of the window sash, the locking nut is rotated and the locking block is locked with the inner side of the window sash, so that the load-bearing component and the window sash can be axially limited and locked.
[0015] The above-mentioned high load-bearing top-hung hinge can be further configured as follows: the height of the locking block under normal conditions is greater than the width of the notch of the window sash groove, and the width of the locking block is less than the width of the notch of the window sash groove.
[0016] By adopting the above technical solution, the groove of the window sash usually has a notch. Under normal circumstances, the height of the locking block is greater than the width of the notch of the window sash groove, and the width is smaller than the width of the notch of the window sash groove. The locking block can be directly placed in the window sash groove, and the locking nut is rotated to rotate the locking block so that the height is rotated to the width. In this state, the width is greater than the notch of the window sash groove, so that the locking block successfully locks the L-shaped load-bearing frame.
[0017] The above-mentioned high load-bearing top-hung hinge can be further configured as follows: a limit plate is provided on the top of the mounting plate, which is limit-engaged with the base when the window sash is closed.
[0018] By adopting the above technical solution, when the window sash is closed, the mounting plate is limitedly engaged with the base through the limit plate, so as to avoid deformation and damage of the hinge parts caused by excessive force during closing, thereby making the product more stable.
[0019] The above-mentioned high load-bearing top-hanging hinge may be further configured as follows: the load-bearing component is provided with a plurality of limiting protrusions on the side facing the gap between the load-bearing component and the mounting plate.
[0020] By adopting the above technical solution, a number of limiting protrusions are provided in the gap of the load-bearing member. On the one hand, the limiting protrusions can maintain the gap when the hinge is not installed, making the hinge installation more convenient. On the other hand, since the load-bearing member is suspended by double-sided rivets, limiting protrusions are provided to limit the swing range of the load-bearing member to avoid excessive swinging amplitude of the load-bearing member.
[0021] The above-mentioned high load-bearing top-hanging hinge may be further configured as follows: an adjustment window is provided at the upper end of the mounting plate, and an eccentric adjustment screw is installed in the adjustment window through the load-bearing member.
[0022] By adopting the above technical solution, the eccentric adjusting screw is used to make adjustments in the adjusting window, and the eccentric adjusting screw causes the mounting plate to move, thereby adjusting the gap between the window sash and the window frame.
[0023] The beneficial effects of the utility model are as follows: a load-bearing member is arranged at the bottom of the mounting plate through a riveted structure, the riveted structure has very high strength, the load-bearing member is adopted to contact with the window sash, the contact surface is increased, and the load-bearing capacity is greatly enhanced; at the same time, due to the hanging setting, the mounting plate has a certain range of motion, which can meet the functions of inward tilting and horizontal opening at the same time.
