[0028] See also Figures 1-12 , respectively are schematic diagrams of the structure of the curtain wall system of the present invention and the structure of its components. As shown in the figure, an embodiment of the present invention provides a curtain wall system, whose overall structure includes a sliding support 1, a support 4, a transmission aluminum rod 6, a corner device 5, an automatic lock tongue kit and a transmission handle 9. There are multiple transmission aluminum rods 6 and automatic lock tongue kits. The sliding support 1 includes a window frame connector, a window sash connector and a sliding rod hinged between the window frame connector and the window sash connector. The automatic lock tongue kit includes an automatic lock tongue assembly 7 and an adjustable lock tongue seat 8. The support 4 includes a window frame fixing part 41, a slide groove 42 and a rocker rod 43 respectively hinged on the window frame fixing part 41 and the slide groove 42.

[0029] The window frame fixing includes a shell 411, an elastic component 412, a roller 413 and an eccentric cam 414. The elastic component 412 is arranged in the shell 411. The elastic component includes a compression spring 4121 and a spring seat 4122 arranged on the compression spring 4121. The roller 413 is arranged on the spring seat 4122. The eccentric cam 414 abuts against the roller 413. One end of the rocker arm 43 is hinged to the eccentric cam 414, and the other end is hinged to the slider 44 in the slide groove 42.

[0030] In one possible implementation, a force adjustment screw 415 is provided at the bottom end of the compression spring 4121 .

[0031] In one possible implementation, an adjustment scale 416 is further provided on the compression spring 4121 .

[0032] Among them, in a possible implementation scheme, the automatic lock tongue assembly includes a mounting seat 71 and a lock tongue 72, a compression spring 73 is provided on the top of the lock tongue 72, a nut 74 is connected to the top of the compression spring 73, and the nut 74 is connected to the mounting seat 71.

[0033] In one possible implementation, a return spring 75 is further provided on one side of the mounting seat 71 relative to the nut 74 . The retractable end of the return spring 75 abuts against the nut 74 , and the other end is fixed to the mounting seat 71 .

[0034] Among them, in a possible implementation scheme, the curtain wall system also includes a locking point kit, there are multiple locking point kits, the locking point kit includes a locking point component 2 and a lock seat 3 that cooperates with the locking point component 2, the locking point component 2 is fixed on the window sash, and the lock seat 3 is fixed on the window frame.

[0035] In one possible implementation, the lock seat 3 is an I-shaped lock seat.

[0036] Based on the curtain wall system structure of the present invention, its working principle is as follows:

[0037] 1) Fan edge operation process: When the transmission handle is rotated, the transmission handle acts on the transmission aluminum rod, the transmission aluminum rod drives the automatic lock tongue assembly, the automatic lock tongue assembly 7 acts on the transmission aluminum rod, the transmission aluminum rod acts on the angler, the angler acts on the transmission aluminum rod, and the transmission aluminum rod acts on the locking point assembly.

[0038] 2) Automatically close the window and lock the sash:

[0039] The window sash is opened and the handle is 90° (see Figure 1 ), when the window is closed manually or when a strong wind blows, the automatic lock tongue will automatically lock the adjustable lock tongue seat (see Figure 2 ), the window sash will not be affected by the indoor and outdoor wind pressure and closed back and forth repeatedly, playing a self-locking effect, effectively ensuring that the window sash is not damaged.

[0040] When a window sash equipped with this type of stay is exposed to strong winds, and the wind force exceeds the stay spring's elasticity, the sash will slowly close automatically in response to the wind pressure. Combined with the automatic latch, the sash will automatically lock after closing. If the window is equipped with an older-model telescopic stay, the stay's internal structure will lock after opening, and strong winds will continue to press against the sash, potentially causing it to flip over, potentially damaging the window or causing it to fall, creating safety concerns. Therefore, the stay and automatic latch mechanism in this system automatically closes and locks the window sash in strong winds, protecting it from damage and preventing accidents.

[0041] 3) The window sash is completely locked:

[0042] After the window sash is closed and the automatic lock tongue is locked (see Figure 2 ), rotate the transmission handle 90° to 0° (see Figure 3 ) At this point, the transmission handle drives the transmission aluminum rod, which drives the automatic deadbolt assembly, which drives the transmission aluminum rod, which drives the angler, which drives the transmission aluminum rod, which drives the locking point assembly. The two deadbolts are released from the adjustable deadbolt base, while all the surrounding locking points engage the base, achieving a fully locked state.

[0043] 4) Open mode:

[0044] After the window sash is fully locked (see Figure 3 ), rotate the transmission handle from 0° to 90° (see Figure 4 At this point, the transmission handle drives the transmission aluminum rod, which drives the automatic lock bolt assembly, which drives the transmission aluminum rod, which drives the angler, which drives the transmission aluminum rod, which drives the locking point assembly. The return spring forces the lock bolt to be retained by the tongue base, and all locking points are released from the base. Once all locking points are released from the base, the window sash can be opened.

[0045] 5) Window sash closing and opening process: Figure 1 → Figure 2 → Figure 3 → Figure 4 → Figure 1 This system can be connected to multiple locking points, that is, a multi-locking point mode around the perimeter to ensure the sealing and airtightness of the window sash.

[0046] Based on the curtain wall system structure of the present invention, when the window is closed, the locking point components around the window sash can be linked by the transmission handle to buckle the lock seat to achieve an excellent sealing effect.

[0047] When actually installing on the left and right sides, there will be installation positioning size errors. The structure of the present invention perfectly solves the size installation error, offsets the fault tolerance, and will not cause the problem of high and low feet when the window sash is opened, because the compression spring is always acting on the roller and the eccentric cam, so that the cam rocker arm is always under force to support the slider.

[0048] The support structure of the present invention is mainly composed of an eccentric cam, a roller, a spring seat, a compression spring, a housing, a force adjustment screw, a cam rocker, a slider, and a slide groove. Under the action of the compression spring and the roller, the eccentric cam of the support acts on the slider, and the slider slides inside the slide to achieve opening and closing. The force adjustment screw is used to adjust the elastic force of the compression spring. When actually installing on the left and right sides, there will be installation and positioning dimensional errors. This structure perfectly solves the dimensional installation error and offsets the fault tolerance. There will be no high and low leg problems when the window sash is opened, because the compression spring is always acting on the roller and the eccentric cam, so that the cam rocker is always under force to support the slider.

[0049] Please combine Figure 8 As shown, the principle of eccentric cam: size OC>OA, OC>OB, AC arc length>CB arc length.

[0050] During the window opening process, the spreader begins to operate. The eccentric cam and roller contact process from A to C, which is the maximum force required to open the window. This process overcomes the sash's own weight and the spring compression force. Due to the short length of the AC arc, this opening force is achieved in an instant. From C to B, the opening force decreases, allowing the window to open easily. Because the dimensions OC to OB gradually decrease, the eccentric cam and roller contact process progresses downward (similar to going from high to low). Therefore, the sash's own weight is overcome by the compression spring, allowing the window to open easily.

[0051] When the window sash is closing, the contact process between the eccentric cam and the roller goes uphill from B to C (similar to from low to high). At this time, the elastic force of the compression spring overcomes the weight of the window sash itself. The window sash will not close instantly under the traction of closing the window and the weight of the window sash itself. Instead, it will be slowly closed by the traction force under the action of the elastic force of the compression spring. This process is very suitable for high-rise buildings or typhoon areas. When the window sash is affected by strong winds from the outside, the window sash will not be closed instantly, causing safety damage accidents. Instead, the window sash will close slowly. Then from C to A, it goes downhill (similar to from high to low). The window sash will automatically close with a certain closing force value. This force value automatically locks the lock tongue. See Figure 2 .

[0052] The automatic lock tongue assembly of the present invention, after the window sash is opened, when the handle is turned 90 degrees, the window is manually pulled to close or the window sash is closed by strong wind from the outside, during the closing process of the window sash, the inclined surface of the automatic lock tongue touches the inclined surface of the adjustable lock tongue seat, and the automatic lock tongue is buckled by the adjustable lock tongue seat due to the elastic action of the internal compression spring (the reset spring ensures the lock tongue position, ensuring that the lock tongue can touch and be buckled with the adjustable lock tongue seat when the window sash is opened and then closed). At this time, all the lock points and the lock seat are disengaged. Figure 9 This process is the window sash locking mode 1 (automatic deadbolt locking).

[0053] After the window sash is closed, the automatic lock tongue locks the window sash. When the handle is operated from 90° to 0°, the automatic lock tongue components on both sides of the handle move simultaneously in the direction of the handle rotation. During this period, the automatic lock tongue touches the inclined surface of the adjustable lock tongue seat, the lock tongue is unlocked and separated from the adjustable lock tongue seat, and the lock point component buckles the lock seat. Figure 10 This process is the window sash locking mode 2 (completely locked).

[0054] When the window sash is fully closed, when the handle is operated from 0° to 90°, the automatic lock tongue assemblies on the left and right sides of the handle move simultaneously in the direction of the handle rotation. Under the action of the reset spring, the lock tongue is blocked by the adjustable lock tongue seat, and the lock point assembly is separated from the lock seat. Figure 11 All locking point components are disengaged from the lock seat and the window sash can be opened. This process is the window sash preparation opening mode.

[0055] In the automatic lock tongue components on the left and right sides of the transmission handle of the present invention, the locking point and the lock tongue do not interfere with or affect each other: when the window sash is closed (the automatic lock tongue component is locked), the lock tongue buckles the adjustable lock tongue seat, and the locking point component is separated from the lock seat; when the window sash is completely locked, the lock tongue is separated from the adjustable lock tongue seat, and the locking point is separated from the lock seat: when ready to be opened, the lock tongue and the locking point are separated from the corresponding adjustable lock tongue seat and the lock seat.

[0056] From the above detailed description of the curtain wall system in combination with the accompanying drawings of the present invention, it can be understood that the curtain wall system includes a sliding support, a support, a transmission aluminum rod, a corner turner, an automatic lock tongue kit and a transmission handle. There are multiple transmission aluminum rods and automatic lock tongue kits. The sliding support includes a window frame connector, a window sash connector and a sliding rod hinged between the window frame connector and the window sash connector. The automatic lock tongue kit includes an automatic lock tongue assembly and an adjustable lock tongue seat. The support includes a window frame fixing part, a slide groove and a rocker rod hinged on the window frame fixing part and the slide groove respectively. By operating the transmission handle, it acts on the transmission aluminum rod, and the transmission aluminum rod acts on the automatic lock tongue assembly to realize automatic closing and locking of the window sash. The presence of the support can effectively prevent the window sash from being repeatedly closed back and forth due to the influence of indoor and outdoor wind pressure, thereby achieving a self-locking effect and effectively ensuring that the window sash is not damaged.

[0057] The curtain wall system of the present invention can be connected to multiple locking points to ensure that the airtightness meets the standard requirements in high-rise windows. At the same time, it can be used in conventional use and can be used in typhoon environments without interfering with each other. The various components are installed using a modular design, and there is no need for milling groove installation (milling-free installation), which makes maintenance and replacement convenient and quick.

[0058] An eccentric cam mechanism and a compression spring mechanism are used inside the support to control the force for opening or closing the window sash. In strong winds, the window sash can be slowly closed along with the strong wind pressure to avoid damage to the window body. It is equipped with an automatic locking function. When the window sash is closed, the lock tongue at the sash edge collides with the tongue seat at the frame edge, and the two are buckled with each other, so the window sash achieves an automatic locking effect. The window sash will not be affected by the indoor and outdoor wind pressure and will be closed back and forth repeatedly, which plays a self-locking protection role and effectively ensures that the window sash is not damaged.
