[0037] The sliding support provided by an embodiment of the present invention is used to install a window sash on a window frame profile, and it includes a fixing component 100, a locking component 200, and a connecting rod component 300. The fixing component 100 is used for fixedly connecting with the window frame profile; the locking component 200 is rotatably connected with the fixing component 100, and the locking component 200 is configured with a locking groove 211; the connecting rod component 300 is used for supporting the window sash; the connecting rod component 300 is rotatably connected with the fixing component 100; a clamping arm 340 is arranged on one side of the connecting rod component 300 close to the locking component 200; when the connecting rod component 300 rotates around its own rotation axis to a preset position, the connecting rod component 300 abuts against the locking component 200 and drives the locking component 200 to rotate around its own rotation axis in a first direction, so that the clamping arm 340 extends into the locking groove 211. Specifically, the first direction is Figure 5 The counterclockwise direction in

[0038] The window sash is installed on the window frame profile through the sliding support provided by the present invention. When the window sash is closed relative to the window frame profile, the connecting rod component 300 rotates around its own rotation axis relative to the fixing component 100 to a preset position. At this time, the connecting rod component 300 abuts against the locking component 200 and drives the locking component 200 to rotate around its own rotation axis in a first direction, so that the clamping arm 340 extends into the locking groove 211, thereby locking the connecting rod component 300 with the locking component 200 at this position. The connecting rod component 300 is not easy to rotate relative to the fixing component 100 under the blowing of a large wind, and the accidental opening of the window sash is less; at the same time, it will also improve the sealing performance of the window sash after closing, and finally make the window sash safer during use.

[0039] In one specific embodiment, the preset position is a specific angular position of the link assembly 300 relative to the fixed assembly 100 when the window sash is closed relative to the window frame profile. For example, the position where the link assembly 300 forms a 15° angle with the fixed assembly 100. Specifically, when the link assembly 300 rotates around its own rotation axis to form a 15° angle with the fixed assembly 100, at this time, the link assembly 300 can abut against the locking assembly 200. When the link assembly 300 continues to rotate around its own rotation axis, it drives the locking assembly 200 to rotate around its own rotation axis along Figure 5 the counterclockwise direction in Figure 5 , and finally, when the window sash is in a fully closed state, the clamping arm 340 can be inserted into the locking groove 211 during the rotation of the locking assembly 200. It should be noted that in other embodiments, the angle between the link assembly 300 and the fixed assembly 100 at the preset position can also be 10°, 20°, or 30°, and there is no specific limitation on this. It can be adaptively modified according to the specific sizes of the link assembly 300 and the locking block 210.

[0040] The following specifically describes the structure of the friction hinge. Please refer to Figure 4 、 Figure 9 and Figure 10 . The locking assembly 200 of the friction hinge provided by an embodiment of the present invention includes a locking block 210. A locking groove 211 is formed on the locking block 210. The side wall of the locking groove 211 includes a first groove wall 2111 and a second groove wall 2112. The first groove wall 2111 and the second groove wall 2112 are arranged at an angle; the first groove wall 2111 can abut against the link assembly 300. A groove wall notch 2114 is provided between the first groove wall 2111 and the second groove wall 2112. The clamping arm 340 can pass through the groove wall notch 2114 and at least partially extend into the locking groove 211. By forming the locking groove 211 on the locking block 210 and providing the groove wall notch 2114 between the first groove wall 2111 and the second groove wall 2112, when the clamping arm 340 rotates to the preset position of the closed window sash driven by the link assembly 300, the clamping arm 340 can pass through the groove wall notch 2114 and extend into the locking groove 211, so that the clamping arm 340 is under the combined limiting action of the first groove wall 2111 and the second groove wall 2112, avoiding sliding out of the locking groove 211 under the blowing of a strong wind and causing the window sash to accidentally open, improving the sealing performance of the window sash and making the use process safer.

[0041] Please refer to Figure 2, A sliding support provided by an embodiment of the present invention further includes a washer 410 and a first connecting member 420. The washer 410 is disposed between the locking block 210 and the fixing assembly 100. One end of the first connecting member 420 passes through the mounting hole on the locking block 210 and the washer 410 and is rotatably connected to the first mounting hole of the fixing assembly 100. Due to the provision of the washer 410, when the locking block 210 rotates relative to the fixing assembly 100, the frictional force between them is relatively small. In one specific embodiment, the first connecting member 420 is a rivet.

[0042] Please refer to Figure 3 and Figure 4 , A sliding support provided by an embodiment of the present invention has a sliding assistance portion 21111 provided on the first groove wall 2111. When the link assembly 300 rotates about its own axis to a preset position, the sliding assistance portion 21111 can abut against the link assembly 300, and during the rotation of the link assembly 300, it can slide along the extension direction of the sliding assistance portion 21111 towards the second groove wall 2112 side to drive the locking block 210 to rotate about its own rotation axis. By providing the sliding assistance portion 21111 on the first groove wall 2111, the link assembly 300 is made more smooth during the process of abutting against the sliding assistance portion 21111 and sliding relative to the sliding assistance portion 21111. In one specific embodiment, the sliding assistance portion 21111 of the sliding support is a fan-shaped structure.

[0043] Please refer to Figure 4 , The number of the sliding assistance portions 21111 provided by an embodiment of the present invention is two, and the two sliding assistance portions 21111 are respectively provided at both ends of the first side wall 321 along its length direction. When the window sash is closed, when the link assembly 300 abuts against the first groove wall 2111 and drives the locking block 210 to rotate counterclockwise, it can be more smooth. Specifically, when the window sash is closed relative to the window frame profile, the link assembly 300 rotates relative to the fixing assembly 100 to a specific angular position. At this time, the link assembly 300 abuts against the first sliding assistance portion 21111 away from the second side wall 322 side. When the link assembly 300 continues to rotate about its own rotation axis, it can slide along the extension direction of the first sliding assistance portion 21111 to the second sliding assistance portion 21111. At this time, the clamping arm 340 and the locking block 210 can be in a fully locked state.

[0044] Please refer to Figures 1 - 3 , The locking assembly 200 of the sliding support provided by an embodiment of the present invention further includes an elastic member 220. The elastic member 220 is rotatably connected to the fixing assembly 100 and abuts against the locking block 210; the locking block 210 can be driven by the elastic member 220 to rotate about its own rotation axis in a second direction, and the second direction is opposite to the first direction. Due to the provision of the elastic member 220, when the window sash is closed, the link assembly 300 drives the locking block 210 to rotate about its own rotation axis along Figure 5In the counterclockwise rotation, the elastic member 220 can be compressed to store energy; when the window sash is opened, the clamping arm 340 of the link assembly 300 moves away from the locking groove 211, and the compressed elastic member 220 releases elastic potential energy, thereby pushing the locking block 210 to rotate along the second direction around its own rotation axis, so that the locking block 210 can quickly return to its original position. Specifically, the second direction is Figure 5 the clockwise direction in

[0045] In one specific embodiment, the elastic member 220 is a torsion spring. The torsion spring includes a first connection end 221 and a second connection end 222. Among them, the first connection end 221 is clamped in the clamping groove 111 of the first fixing plate 110, and the second connection end 222 abuts against the locking block 210. When the locking block 210 rotates around its own rotation axis along Figure 5 the counterclockwise direction in Figure 5 the torsion spring is twisted and stores energy under the action of the locking block 210, and at the same time, the clamping arm 340 is inserted into the locking groove 211 to realize the self-locking function with the locking block 210. When the window sash is opened again, at this time, the link assembly 300 is pushed, so that the clamping arm 340 moves away from the locking groove 211, and at the same time, the locking block 210 can quickly rotate along Figure 5 the clockwise direction in

[0046] Please refer to Figure 2 . The sliding support provided by an embodiment of the present invention further includes a second connecting member 430. The second connecting member 430 passes through the mounting hole of the torsion spring and is rotatably connected to the second mounting hole on the fixing assembly 100. In one specific embodiment, the second connecting member 430 is a rivet.

[0047] It should be noted that the first mounting hole and the second mounting hole on the fixing assembly 100 are arranged in a staggered manner. Therefore, when the locking block 210 and the torsion spring rotate around their own rotation axes, the situation of jamming due to synchronous rotation during the rotation process can be reduced.

[0048] Please refer to Figures 1 - 3 . The side wall of the locking block 210 of the sliding support provided by an embodiment of the present invention further includes a third groove wall 2113. The third groove wall 2113 is arranged opposite to the first groove wall 2111; the elastic member 220 abuts against the third groove wall 2113. By providing the third groove wall 2113, the elastic member 220 is easily abutted against the side wall of the locking block 210. Specifically, when the elastic member 220 is a torsion spring, the second connection end 222 of the torsion spring can be conveniently abutted against the third groove wall 2113 of the locking block 210.

[0049] Please refer to Figure 1 , Figure 2 , Figure 5 and Figures 7 - 9 , in a linkage assembly 300 of a friction hinge provided by an embodiment of the present invention, it includes a first link 310, a second link 320 and a third link 330; one end of the first link 310 is rotatably connected to the fixing assembly 100, and the other end of the first link 310 is rotatably connected to the third link 330; one end of the second link 320 is rotatably connected to a side of the fixing assembly 100 close to the locking block 210, and the other end of the second link 320 is rotatably connected to the third link 330; the third link 330 is used to support the window sash, and a clamping arm 340 is configured on the third link 330; the third link 330 can drive the clamping arm 340 to extend into the locking groove 211 under the drive of the first link 310 and the second link 320. A four-bar mechanism is jointly formed by the first link 310, the second link 320, the third link 330 and the fixing assembly 100 to drive the opening and closing of the window sash relative to the window frame profile.

[0050] Please refer to Figure 1 , Figure 2 and Figure 5 , in an embodiment of the present invention, for the second link 320 of the friction hinge, the two sides along its length direction are respectively a first side wall 321 and a second side wall 322; the second link 320 is provided with a first inclined surface 323, and the first inclined surface 323 is formed by inclining upward from the first side wall 321 towards the second side wall 322, and the first inclined surface 323 can abut against the locking block 210. By providing the first inclined surface 323 on the second link 320 and making the first inclined surface 323 able to abut against the locking block 210, when the second link 320 pushes the locking block 210 to rotate around its own rotation axis, it can abut against the second groove wall 2112 of the locking block 210 more conveniently and smoothly. Specifically, the length direction of the third link 330 is Figure 5 the yy' direction in

[0051] Please refer to Figure 5 and Figure 6, in an embodiment of the present invention, the clamping arm 340 of the sliding support is tapered towards the side of the locking block 210 along the length direction of the third link 330. The tapered structure includes a second inclined surface 341. When the clamping arm 340 extends into the locking groove 211, the second inclined surface 341 is disposed on the side of the clamping arm 340 close to the second groove wall 2112. Since the clamping arm 340 is tapered towards the side of the locking block 210 along the length direction of the third link 330, and when the clamping arm 340 extends into the locking groove 211, the second inclined surface 341 is disposed on the side of the clamping arm 340 close to the second groove wall 2112, when the clamping arm 340 extends into or out of the locking groove 211 through the groove wall notch 2114, it can be more convenient and easier, reducing the collision between the clamping arm 340 and the second groove wall 2112. Specifically, the length direction of the third link 330 is Figure 5 the xx' direction in

[0052] Please refer to Figures 1 - 3 , the fixing component 100 of the sliding support provided by an embodiment of the present invention includes a first fixing plate 110 and a second fixing plate 120 fixedly connected thereto, and the first fixing plate 110 and the second fixing plate 120 are disposed at an angle; both the first link 310 and the second link 320 are rotatably connected to the first fixing plate 110, and the locking component 200 is rotatably connected to the first fixing plate 110. By rotatably connecting the first fixing plate 110 to the first link 310 and the second link 320 respectively, and rotatably connecting the third link 330 to the first link 310 and the second link 320 respectively, a four-bar mechanism is jointly formed. When the window sash needs to be opened and closed relative to the window frame profile, it is realized by the rotation of the first link 310 and the second link 320 relative to the first fixing plate 110, and then driving the rotation of the third link 330 relative to the first link 310 and the second link 320.

[0053] Please refer to [[ID= , the second fixing plate 120 of the sliding support provided by an embodiment of the present invention is provided with a mounting groove 121 recessed inward along its thickness direction; when the locking block 210 rotates around its own rotation axis, the second groove wall 2112 can rotate relative to the groove wall of the mounting groove 121 and can be at least partially received in the cavity of the mounting groove 121. By providing the through mounting groove 121 on the second fixing plate 120, when the locking block 210 rotates around its own rotation axis, the second groove wall 2112 can rotate relative to the groove wall of the mounting groove 121 and be at least partially received in the cavity of the mounting groove 121. The whole sliding support is not only more beautiful but also can avoid the collision between the second groove wall 2112 and the second fixing plate 120.

[0054] In one specific embodiment, the installation groove 121 is a through groove that is recessed inward along the thickness direction of the second fixing plate 120. Therefore, the volume of the cavity of the installation groove 121 is relatively large. When the second groove wall 2112 rotates relative to the groove wall of the installation groove 121, the volume of itself accommodated in the installation groove 121 is also relatively large. Furthermore, when the window sash is in the open state, it can be more aesthetically pleasing.

[0055] In another specific embodiment, the installation groove 121 does not penetrate along the thickness direction of the second fixing plate 120, and it is a blind groove with an opening facing the side of the second groove wall 2112. It should be noted that there are no restrictions on whether the installation groove 121 penetrates along the thickness direction of the second fixing plate 120 and the depth dimension of the installation groove 121. It can be adaptively modified according to the thickness dimension of the second fixing plate 120 itself and the volume size required for the second groove wall 2112 to be accommodated in the installation groove 121.

[0056] In one specific embodiment, when the window sash is in the open state, at least a part of the second groove wall 2112 of the locking block 210 is accommodated in the installation groove 121 and abuts against the bottom wall of the installation groove 121. At this time, the torsion spring is in a stressed or slightly stressed state. Therefore, when the window sash is in the open state, the locking block 210 is not easily rotated around its own rotation axis, and the stability of the opening angle of the window sash is relatively high. When the window sash needs to be closed, under the abutting and pushing action of the second connecting rod 320, the locking block 210 can rotate around its own rotation axis in the first direction.
