[0001] The utility model relates to the technical field of building doors and windows, and in particular to a flat hinge which is not distinguished between left and right. Background Art

[0002] Windows are generally part of a building and can play the role of light transmission and ventilation. Whether it is a residential building or an industrial plant, it is necessary to install windows to ensure lighting and ventilation. Windows can be divided into casement windows and sliding windows according to the opening method. With the advancement of technology, casement windows have the advantages of good ventilation, security and anti-theft, and sealing and heat preservation and are widely used.

[0003] At present, casement windows are generally opened by turning over the top or bottom hinges. However, the existing casement hinges are not universal on the left and right sides, so they need to be prepared separately when stocking. Moreover, since the left and right sides are symmetrically arranged, it is easy to take the wrong one during the actual installation process, which is very inconvenient. Utility Model Content

[0004] Based on this, in order to solve the above problems, the utility model provides a flat hinge that does not distinguish between left and right.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0017] Figure 3 It is a structural schematic diagram of the displacement regulating mechanism of the utility model. 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 of 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 As shown, the utility model is a flat hinge that is not divided into left and right, comprising a fan blade 10 installed on the window sash and a frame blade 11 installed on the window frame. The fan blade 10 and the frame blade 11 are rotatably connected through a rotating shaft.

[0020] Combination Figure 2 As shown, the fan blade 10 includes a bracket 12, a hinge 13 and a shaft sleeve 14. One end of the hinge 13 is integrally connected to the shaft sleeve 14, and the other end is provided with a first shaft hole 131. A second shaft hole 132 is provided on the bracket 12 at a position corresponding to the first shaft hole 131. A pin 15 is provided in the two shaft holes to connect the hinge 13 and the bracket 12 together, and the hinge 13 can rotate around the pin 15. A locking structure 20 is also included for fixing the hinge after rotation to limit the relative rotation of the hinge and the bracket.

[0021] It should be noted here that the initial state of the sleeve 14 is a horizontal setting. When the hinge 13 is rotated 90° clockwise, the sleeve 14 changes from a horizontal state to a vertical state, and is located on one side of the bracket 12 and fixed by the locking structure 20 to form a first use state. Similarly, when the hinge 13 is rotated 90° counterclockwise, the sleeve 14 changes from a horizontal state to a vertical state, and is located on the other side of the bracket 12 and fixed by the locking structure 20 to form a second use state. When the casement hinge is installed on the window sash, the left and right reversing of the hinge 13 can be achieved by switching between the first use state or the second use state, thereby meeting different installation requirements.

[0022] like Figure 2 As shown, the bracket 12 includes a first angle plate 121 and a second angle plate 122 located below the first angle plate 121. A first mounting hole 123 is provided on the first angle plate 121, and a second mounting hole 124 is provided on the second angle plate 122 at a position corresponding to the first mounting hole 123. A fixing screw 125 is provided in the first mounting hole 123, and the end of the fixing screw 125 passes through the first mounting hole 123 and is tightened in the second mounting hole 124 to fix the first angle plate 121 and the second angle plate 122 together.

[0023] like Figure 1 and Figure 2As shown, the locking structure 20 includes a protruding positioning block 21 provided on the inner side surface of the vertical portion of the first angle plate 121, and a first limiting hole 22 and a second limiting hole 23 symmetrically provided on both sides of the hinge 13 to cooperate with the positioning block. When in use, the hinge is rotated 90° clockwise and located on one side of the bracket 12, and the positioning block 21 is embedded in the first limiting hole 22, thereby fixing the hinge to form a first use state. Similarly, the hinge is rotated 90° counterclockwise and located on the other side of the bracket 12, and the positioning block 21 is embedded in the second limiting hole 23, thereby fixing the hinge to form a first use state.

[0024] like Figure 1 As shown, a guide notch 24 is provided on the upper edge of the vertical outer side of the hinge 13. A guide slope is provided in the guide notch 24. In this embodiment, there are two notches 24. In this way, when the flat hinge is switched between the first use state and the second use state, when the hinge is rotated, the positioning block 21 can easily slide into the first limiting hole 22 or the second limiting hole 23 through the guide slope of the guide notch 24.

[0025] Combination Figure 3 As shown, a displacement adjustment mechanism 30 is provided between the first angle plate 121 and the second angle plate 122 .

[0026] The displacement adjustment mechanism 30 includes an adjustment bolt 31 and a receiving groove 32 provided at the horizontal portion of the first angle plate. A boss 33 matching the receiving groove 32 is provided on the top surface of the second angle plate 122. A threaded hole 34 extending axially and matching the adjustment bolt 31 is provided on the end surface of the boss 34. The boss 33 is inserted into the receiving groove 32, and the end of the adjustment bolt 31 passes through the threaded hole 34 and abuts against the front end surface of the receiving groove 32. When in use, unscrew the fixing screw 125 between the first angle plate 121 and the second angle plate 122, rotate the adjusting bolt 31, adjust the position between the first angle plate 121 and the second angle plate 122, and then tighten the fixing screw 125 to fix the position between the first angle plate 121 and the second angle plate 122. In this way, by adjusting the displacement of the first angle plate, the displacement adjustment of the window sash is realized, which is very convenient.

[0027] In this embodiment, the fan blade 10 is made of carbon steel. Carbon steel has high strength, can withstand large external forces and pressures, and can be processed into various shapes through forging, rolling and other processes, which is easy to manufacture. At the same time, compared with other alloy steels, carbon steel has a lower production cost and the raw materials are easy to obtain, so the price is relatively economical.

[0028] During installation, first, according to the different installation requirements of the left and right window sashes, the casement hinge is switched to the first use state or the second use state. Then, the fan blade 10 and the frame blade 11 are installed on the window frame and the window sash respectively. Then, the window sash and the window frame are assembled together, and the fan blade 10 and the frame blade 11 are connected as a whole through a rotating shaft to complete the assembly.

[0029] In summary, the utility model realizes left-right reversal by rotating the hinge clockwise or counterclockwise and then fixing the hinge, thereby meeting different installation requirements of left and right window sashes. The structure is simple and easy to use.

[0030] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
