For those skilled in the art, the specific meaning of the terms in the present application can be understood according to the specific circumstances.

[0036] Reference is made to Figure 1The embodiment discloses a window body, which comprises a window frame 2, a window sash 3 and a sliding device 1 connected between the window frame 2 and the window sash 3. Specifically, the sliding device 1 is applied to the upper transmission of the inwardly-inclined sliding window sash, and can realize that the window sash 3 cannot be translated and slid in the process of being pushed open, and the window sash 3 cannot be pushed open in the process of being translated and slid.

[0037] Referring to Figures 2-11 The sliding device 1 comprises a sliding frame 10, a swing arm assembly 20, a self-locking assembly 30 and a limiting assembly 40. The sliding frame 10 is slidably connected in a sliding rail of the window frame 2. One end of the swing arm assembly 20 is rotatably connected to the sliding frame 10, and the other end of the swing arm assembly 20 is used for connecting the window sash 3. The limiting assembly 40 is fixed to the window frame 2. The self-locking assembly 30 is self-rotatably connected to the sliding frame 10, and is provided with a first end 31, a second end 32 and a third end 33. The second end 32 is used for being in contact with one end of the swing arm assembly 20, so that the one end of the swing arm assembly 20 can be rotated. The first end 31 is clamped with the limiting assembly 40, and the sliding frame 10 is limited in the sliding rail of the window frame 2. The third end 33 is used for abutting against one end of the swing arm assembly 20, so that the one end of the swing arm assembly 20 cannot be rotated. The first end 31 is separated from the limiting assembly 40, and the sliding frame 10 can be slid in the sliding rail of the window frame 2.

[0038] Further referring to Figures 2-4 The working principle of the sliding device 1 is as follows:

[0039] When the window sash 3 is closed in the window frame 2, the first end 31 is clamped with the limiting assembly 40, and the sliding frame 10 is limited in the initial position in the sliding rail of the window frame 2 and cannot be moved. At this time, one end of the swing arm assembly 20 can be rotated to push out the window sash 3.

[0040] Before the window sash 3 is pushed out of the window frame 2 and not opened to the maximum angle, the second end 32 keeps in contact with one end of the swing arm assembly 20, so that the first end 31 is stably clamped with the limiting assembly 40, and the sliding frame 10 is still limited in the initial position in the sliding rail of the window frame 2 and cannot be moved.

[0041] When the window sash 3 is opened to the maximum angle, the second end 32 is separated from one end of the swing arm assembly 20, and the self-locking assembly 30 is rotated to the third end 33 abutting against one end of the swing arm assembly 20 under the driving of the self-rotation force, so that one end of the swing arm assembly 20 is self-locked and cannot be rotated. At the same time, the self-locking assembly 30 is rotated to separate the first end 31 from the limiting assembly 40, and the sliding frame 10 is in the initial position and can be slid in the sliding rail of the window frame 2.

[0042] After the sliding frame 10 drives the window sash 3 to be translated and slid out of the initial position, the swing arm assembly 20 keeps being self-locked under the abutting force of the self-locking assembly 30, and the window sash 3 cannot be pushed out or pulled in.

[0043] When the sliding frame 10 is translated to the initial position again, the limiting assembly 40 is in contact with the self-locking assembly 30, and under the action of the sash 3, the limiting assembly 40 applies a counter force to the self-locking assembly 30, so that the self-locking assembly 30 is reversely rotated to the first end 31 being clamped with the limiting assembly 40, thereby limiting the sliding frame 10, and one end of the swing arm assembly 20 is rotatably pulled into the sash 3 to close the sash 3 into the window frame 2.

[0044] The sliding device 1 in the scheme acts on the transmission connection position of the sash 3 and the window frame 2, can limit the translation of the sash 3 when the sash 3 is pushed open, and the self-locking swing arm assembly 20 avoids the sash 3 from shaking when the sash 3 is translated, thereby improving the smoothness in the opening and closing process of the sash 3.

[0045] Referring to Figures 5-7 , the swing arm assembly 20 comprises a swing arm rod 202 and a rotating piece 201, the rotating piece 201 is rotatably connected to the sliding frame 10, one end of the swing arm rod 202 is fixedly connected with the rotating piece 201, and the other end of the swing arm rod 202 is rotatably connected with the sash 3. When the sash 3 is manually or automatically pushed open or closed, one end of the swing arm rod 202 drives the rotating piece 201 to rotate on the sliding frame 10, and the other end of the swing arm rod 202 is rotatably connected to the sash 3.

[0046] Referring to Figures 8-9 , the self-locking assembly 30 comprises a self-locking hook 301 and an elastic piece 302, the self-locking hook 301 is rotatably connected to the sliding frame 10 through a first rotating shaft 103, the elastic piece 302 is sleeved on the first rotating shaft 103, one end of the elastic piece 302 is connected to the sliding frame 10, the other end of the elastic piece 302 is connected to the self-locking hook 301, and the elastic piece 302 applies an action force to the self-locking hook 301 to rotate the third end 33 to the direction close to the swing arm assembly 20. The first end 31, the second end 32 and the third end 33 are sequentially arranged on the circumference of the self-locking hook 301.

[0047] It can be understood that the elastic piece 302 in the scheme can be any one of a torsion spring, a spring or a spring piece. The self-rotation direction of the self-locking hook 301 is consistent with the rotation direction of the rotating piece 201 pushing out the sash 3.

[0048] Specifically, the first end 31 is provided with a first clamping part 311, and the limiting assembly 40 is provided with a second clamping part 41; when the second end 32 is in contact with one end of the swing arm assembly 20, the first clamping part 311 is matched with the second clamping part 41, so that the self-locking assembly 30 and the limiting assembly 40 are relatively fixed.

[0049] Referring to Figures 10-11In one embodiment, the first clamping part 311 is a clamping groove, and the second clamping part 41 is a clamping hook corresponding to the first clamping part 311. The first clamping part 311 includes a clamping groove bottom surface 3111, a first clamping groove side surface 3112, and a second clamping groove side surface 3113. The size of the clamping groove bottom surface 3111 is slightly larger than the size of the clamping hook. The angle between the clamping groove bottom surface 3111 and the first clamping groove side surface 3112 is a right angle, and the angle between the clamping groove bottom surface 3111 and the second clamping groove side surface 3113 is an obtuse angle. The second clamping part 41 includes a clamping hook top surface 411, a first clamping hook side surface 412, and a second clamping hook side surface 413. The angle between the clamping hook top surface 411 and the first clamping hook side surface 412 and the angle between the clamping hook top surface 411 and the second clamping hook side surface 413 are both right angles. When the clamping hook is clamped in the clamping groove, the first clamping groove side surface 3112 is in contact with the first clamping hook side surface 412, and the first clamping groove side surface 3112 is inclined to the first clamping hook side surface 412. When the self-locking assembly 30 rotates, the connection position of the second clamping hook side surface 413 and the second clamping hook bottom surface can rotate along the second clamping groove side surface 3113, so as to realize the disengagement of the first clamping part 311 and the second clamping part 41.

[0050] In another embodiment, the first clamping part 311 is a clamping hook, and the second clamping part 41 is a clamping groove corresponding to the first clamping part 311. The specific clamping manner is the same as that in the previous embodiment.

[0051] It should be noted that the present scheme is not limited to the structure design of the first clamping part 311 and the second clamping part 41 described above. As long as the first clamping part 311 and the second clamping part 41 can realize the alternation of the limiting action and the sliding action of the sliding frame 10 through the cooperation of the self-locking assembly 30 and the limiting assembly 40, the structure of the first clamping part 311 and the second clamping part 41 is a simple transformation and change of the present scheme, and should fall within the protection scope of the present scheme.

[0052] Further, the second end 32 is provided with a first arc-shaped contact part 321, and one end of the rotating piece 201 is provided with a second arc-shaped contact part 22. The first arc-shaped contact part 321 is in contact with the second arc-shaped contact part 22, so that when the rotating piece 201 can rotate, the self-locking hook 301 cannot rotate.

[0053] In one embodiment, the first arc-shaped contact part 321 is provided with an arc-shaped track. The arc shape of the arc-shaped track is consistent with the rotating direction of the swing arm assembly 20, and the arc degree of the arc-shaped track is greater than or equal to the rotation angle of the swing arm assembly 20 rotating to the preset position. Therefore, before the swing arm assembly 20 rotates to the preset position, the self-locking assembly 30 cannot rotate. At this time, the second arc-shaped contact part 22 can be an arc-shaped contact rail or an arc-shaped contact slider which is matched with the arc-shaped track. The second arc-shaped contact part 22 can be in surface-to-surface contact or point-to-surface contact, as long as the first arc-shaped contact part 321 can be kept stationary when the second arc-shaped contact part 22 rotates.

[0054] In another embodiment, the second arc-shaped contact portion 22 is provided with an arc-shaped track, and the first arc-shaped contact portion 321 is provided with an arc-shaped contact rail or an arc-shaped contact slider matched with the arc-shaped track, and the rotation principle is the same as that of the previous embodiment.

[0055] Further, the third end 33 is provided with a first abutting portion 331, and one end of the swing arm assembly 20 is provided with a second abutting portion 21. When the second end 32 is separated from one end of the swing arm assembly 20, the self-locking assembly 30 rotates, and after the first abutting portion 331 abuts against the second abutting portion 21, the self-locking assembly 30 stops rotating, and the swing arm assembly 20 cannot rotate.

[0056] In an embodiment, the first abutting portion 331 is provided with an abutting protrusion, and the second abutting portion 21 is provided with an abutting groove. After the second end 32 is separated from the rotating piece 201, the self-locking hook 301 rotates to make the abutting protrusion rotate downward, so that the abutting protrusion enters the abutting groove.

[0057] It can be understood that the distance between the second arc-shaped contact portion 22 and the second rotating shaft 104 is greater than the distance between the second abutting portion 21 and the second rotating shaft 104, and / or the distance between the first arc-shaped contact portion 321 and the first rotating shaft 103 is less than the distance between the first abutting portion 331 and the first rotating shaft 103, so as to ensure that the second end 32 of the self-locking hook 301 can still abut against the rotating piece 201 through the third end 33 after being separated from the rotating piece 201.

[0058] In another embodiment, the first abutting portion 331 is provided with an abutting groove, and the second abutting portion 21 is provided with an abutting protrusion, and the abutting principle is the same as that of the previous embodiment.

[0059] Further, the self-locking hook 301 is provided with a first limiting groove 3011, and the sliding frame is provided with a first limiting column 101, which is inserted into the first limiting groove 3011, for limiting the rotation angle and rotation position of the self-locking hook 301. In other embodiments, the first limiting groove 3011 can also be arranged on the sliding frame, and the first limiting column 101 can be arranged on the self-locking hook 301, and the same effect of limiting the rotation angle and rotation position of the self-locking hook 301 can also be achieved.

[0060] In the present embodiment, the rotating piece 201 is provided with a second limiting groove 2011, and the sliding frame is provided with a second limiting column 102, which is inserted into the second limiting groove 2011, for limiting the rotation angle and rotation position of the rotating piece 201. In other embodiments, the second limiting groove 2011 can also be arranged on the sliding frame, and the second limiting column 102 can be arranged on the rotating piece 201, and the same effect of limiting the rotation angle and rotation position of the rotating piece 201 can also be achieved.

[0061] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement and improvement etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
