[0002] In building construction, the use of high-load-bearing doors and windows is becoming increasingly common. However, under high loads or after prolonged use, doors and windows are prone to natural sagging, affecting normal opening and closing and posing a safety hazard. Furthermore, the locking and sealing performance of doors and windows is becoming increasingly important. Current technologies typically address this issue by separately incorporating anti-sinking and locking / sealing structures into the transmission components, which is costly and cumbersome to install. Utility Model Content

[0003] The purpose of this utility model is to provide a supporting and locking structure and its doors and windows, so as to achieve a simple and low-cost anti-sinking support and locking function.

[0004] The first aspect of this utility model discloses a support and locking structure, including a load-bearing component and a support component. The load-bearing component includes a load-bearing base and a first locking member. The load-bearing base is fixed to the side of the fan body, and the first locking member is slidably connected to the side of the fan body.

The support component includes a second locking member and a rotatable support member. The second locking member is connected to the support member, and the top of the support member is provided with a support portion. When the fan body is closed onto the frame, the support part pushes the load-bearing part from bottom to top to prevent the fan body from sagging; the first locking member and the second locking member cooperate to lock the fan body onto the frame. When the fan body is suspended from the frame, the support part tilts upwards to support the load-bearing part, thereby suspending and supporting the fan body.

[0005] Optionally, the support member is an eccentric support member with a thicker bottom than top, and before the fan body closes to the frame, the support part extends vertically upward along the length of the frame.

[0006] Optionally, the support assembly further includes a base and a rotating shaft. The base is connected to the frame, one end of the rotating shaft is connected to the base, and the other end of the rotating shaft is rotatably connected to the support member.

[0007] Optionally, the first locking element is a lock head structure, which is connected to an external transmission device; the second locking element is a lock head limiting structure, with the support part located at one end of the support member and the lock head limiting structure located at the other end of the support member, and the transmission device used to drive the lock head structure to engage with the lock head limiting structure. Optionally, the lock head limiting structure and the support member are integrally formed.

[0008] Optionally, the first locking element is a lock head limiting structure, which is connected to an external transmission device; the second locking element is a lock head structure, which is located at the rotation center of the support member, and the transmission device is used to drive the lock head limiting structure until the lock head structure is engaged within the lock head limiting structure.

[0009] Optionally, the fixed surface of the load-bearing seat is provided with a clearance groove, which is used for the transmission device to pass through and connect to the first locking member. Optionally, the load-bearing component is located at the top or bottom of the side of the fan body, and an angle actuator is provided at the top or bottom of the side of the fan body. The load-bearing seat is connected to the angle actuator seat of the angle actuator, and the first locking member is connected to the angle actuator bar of the angle actuator.

[0010] Optionally, the extended end of the support portion is provided with an arc-shaped protrusion, and the load-bearing portion is provided with an arc-shaped groove that matches the shape of the arc-shaped protrusion. One end of the groove opening of the arc-shaped groove is lower than the other end of the groove opening of the arc-shaped groove, which is used to block the support portion to prevent the support portion from rotating out of the arc-shaped groove.

[0011] Optionally, the base is provided with a first rotation limiting part, and the support is provided with a second rotation limiting part. The first rotation limiting part and the second rotation limiting part are adapted to each other to limit the rotation angle of the support.

[0012] Optionally, the first rotation limiting part is an arc-shaped groove that corresponds to the rotation trajectory of the support member, and the second rotation limiting part is a limiting block that slides within the arc-shaped groove.

[0013] Optionally, the base includes a base plate, an adjusting plate, and a height adjusting component. The base plate is fixed to the fan body, the rotating shaft is fixed to the adjusting plate, and the height adjusting component is disposed between the base plate and the adjusting plate to adjust the relative position between the adjusting plate and the base plate.

[0014] The second aspect of this utility model discloses a door and window, including a frame and a sash, wherein a support and locking structure as described above is provided between the frame and the sash.

[0015] Optionally, the door / window includes an upturned state and a locked state.

The first height is greater than or equal to the second height, which is used to support the sash body when it is suspended from the frame.

[0016] The beneficial effects of this utility model are as follows: The support-locking structure in this solution places the load-bearing component on the window sash and the support component on the frame. When the window sash is closed to the frame, the support automatically supports the load-bearing component. At this point, the height of the load-bearing component is at the normal closed height of the window, and part of the weight of the window sash is borne by the support, thus preventing the window sash from sinking due to its own weight. Simultaneously, by moving the first locking element, it engages with the second locking element to further lock the window sash, improving the sealing performance of the door and window. This support-locking structure is simple in construction, easy to operate, solves the risk of window sash sinking, and simultaneously locks the door and window, improving their safety and sealing.

For those skilled in the art, the specific meaning of the terms in this utility model can be understood according to the specific circumstances.

[0021] See Figure 1 This utility model discloses a door and window, which can be a casement window. The door and window includes a frame 2 and a sash 3, and a supporting locking structure 1 is provided between the frame 2 and the sash 3.

[0022] The supporting locking structure 1 of this solution can also be applied to top-hung windows, see [link / reference]. Figure 13 In the top-hung window, the load-bearing base 11 is fixed to the top side of the sash 3, serving both to support and lock the sash 3 when it is closed, and to support its weight during the top-hung phase. This top-hung window includes a top-hung state and a locked state. In the top-hung state, the contact point between the support part 211 and the load-bearing part 111 is at a first height H1 from the rotation center of the support member 21. In the locked state, the contact point between the support part 211 and the load-bearing part 111 is at a second height H2 from the rotation center of the support member 21, where H1 ≥ H2. This height supports the sash when it is suspended from the frame.

[0023] See Figure 2-3 , Figure 6-7 as well as Figure 10-11 The supporting locking structure 1 includes a load-bearing component 10 and a support component 20. The load-bearing component 10 includes a load-bearing seat 11 and a first locking member. The load-bearing seat 11 is fixed to the side of the fan body 3, and the first locking member is slidably connected to the side of the fan body 3. The load-bearing seat 11 has a load-bearing part 111 at the bottom. The support component 20 is connected to the side of the frame 2. The support component 20 includes a rotatable support member 21 and a second locking member. The second locking member is connected to the support member 21, and the support member 21 has a support part 211 at the top. When the fan body 3 is closed onto the frame 2, the support part 211 pushes the load-bearing part 111 from bottom to top to prevent the fan body 3 from sagging; the first locking member and the second locking member cooperate to lock the fan body 3 onto the frame 2. When the fan body 3 is suspended from the frame 2, the support part 211 tilts upward to support the load-bearing part 111, which is used to suspend and support the fan body 3.

[0024] In this solution, the support-locking structure 1 places the load-bearing component 10 on the sash 3 and the support component 20 on the frame 2. After the sash 3 closes into the frame 2, the support part 211 automatically supports the load-bearing part 111. At this time, the height of the load-bearing part 111 is at the normal closing height of the window, and part of the weight of the sash 3 is borne by the support part 211, thus preventing the sash 3 from sinking due to its own weight. At the same time, by moving the first locking member, the first locking member cooperates with the second locking member to further lock the sash 3, improving the sealing performance of the door and window. The support-locking structure 1 of this solution has a simple structure, is easy to operate, can solve the risk of the sash 3 sinking, and can also lock the door and window, improving the safety and sealing of the door and window.

[0025] In this embodiment, the support member 21 is an eccentric support member with a thicker bottom than top. Before the fan body 3 closes into the frame 2, the support part 211 extends vertically upward along the length of the frame 2. The eccentric support member 21 is stable within the frame 2 under its own weight. After the fan body 3 closes, the support part 211 of the support member 21 can rotate to support the load-bearing part 111 under the action of the load-bearing part 111, thus providing protection. Making the support member 21 an eccentric member ensures that the support member 21 can rotate, and at the same time, when supporting the load-bearing part 111, it can react to the load-bearing part 111 with its own weight, increasing the support stability of the load-bearing part 111 and the support part 211.

[0026] The extended end of the support portion 211 is provided with an arc-shaped protrusion 2111, and the load-bearing portion 111 is provided with an arc-shaped groove 1111 that matches the shape of the arc-shaped protrusion 2111. One end of the groove of the arc-shaped groove 1111 is lower than the other end of the groove of the arc-shaped groove 1111, which is used to block the support portion 211 to prevent the support portion 211 from rotating out of the arc-shaped groove 1111. It should be noted that the curvature of the arc-shaped groove 1111 should not be less than the curvature of the arc-shaped protrusion 2111, so as to ensure that the arc-shaped protrusion 2111 does not detach from the arc-shaped groove 1111 during rotation.

[0027] See further Figure 4 , Figure 8 as well as Figure 12 The support assembly 20 also includes a base 23 and a rotating shaft 24. The base 23 is connected to the frame 2, one end of the rotating shaft 24 is connected to the base 23, and the other end of the rotating shaft 24 is rotatably connected to the support member 21. Understandably, the support member 21 can be rotatably connected to the base 23 via the rotating shaft 24.

[0028] In this embodiment, the base 23 is provided with a first rotation limiting part 2321, and the support member 21 is provided with a second rotation limiting part 212. The first rotation limiting part 2321 and the second rotation limiting part 212 are adapted to each other to limit the rotation angle of the support member 21. Specifically, the first rotation limiting part 2321 is an arc-shaped groove that corresponds to the rotation trajectory of the support member 21, and the second rotation limiting part 212 is a slider that slides within the arc-shaped groove. The cooperative use of the first rotation limiting part 2321 and the second rotation limiting part 212 allows the support member 21 to more stably perform the functions of support and locking.

[0029] In one embodiment, the base 23 includes a base plate 231, an adjusting plate 232, and a height adjusting member 233. The base plate 231 is fixed to the fan body 3, the rotating shaft 24 is fixed to the adjusting plate 232, and the height adjusting member 233 is disposed between the base plate 231 and the adjusting plate 232 to adjust the relative position between the adjusting plate 232 and the base plate 231, thereby adjusting the height of the support assembly 20 and making the support assembly 20 and the load-bearing assembly 10 more tightly abut against each other. A first rotation limiting part 2321 is disposed on the adjusting plate 232.

[0030] The height adjustment component 233 is an eccentric component. The base plate 231 is provided with a positioning hole 2311, and the adjustment plate 232 is provided with an eccentric hole 2322. The eccentric component includes a fixed part, an eccentric part, and an adjustment part. The eccentric part is located between the fixed part and the adjustment part. The eccentric part is rotatably connected in the positioning hole 2311 and is sleeved in the eccentric hole 2322. The adjustment part is used to rotate the fixed part and the eccentric part to adjust the height of the adjustment plate 232.

In this embodiment, the lock head limiting structure is a stop edge adapted to the shape of the lock head structure, and the stop edge and the support member 21 are integrally formed. Producing a single support member 21 can simultaneously provide support and locking functions, making it easy to manufacture, install, and operate, and significantly reducing production costs.

[0032] See Figure 6-9 Unlike the first embodiment, in the second embodiment, the first locking member 12B is a lock head limiting structure, which is connected to the external transmission device 4. This lock head limiting structure can be a stop or a stop, as long as it can limit the lock head structure to lock the fan body. The second locking member 22B is a lock head structure, which is located at the rotation center of the support member 21. The lock head structure is a rotating shaft 24. The support member 21 is rotatably connected to the base 23 through the lock head structure. The transmission device 4 is used to drive the lock head limiting structure until the lock head structure is engaged within the lock head limiting structure. The lock head structure directly acts as the rotating shaft 24, which can connect the support member 21 and also ensure the stability of the lock head assembly. In the first and second embodiments, the lock head structure is an eccentric lock head. The eccentric lock head is used to adjust the offset to fit the lock head limiting structure and ensure the sealing performance after the fan body is locked.

[0033] In the first and second embodiments, depending on the position of the transmission device 4, the fixed surface of the support seat 11 is provided with a clearance groove 112, which is used for the transmission device 4 to pass through and connect to the first locking member.

[0034] See Figure 10-13 Unlike the first embodiment, the rotating device in the third embodiment is an angle transmission device 4C, the load-bearing component 10 is located on the top or bottom side of the fan body 3, the load-bearing seat 11 is connected to the angle transmission seat 41 of the angle transmission device 4C, and the first locking member 12A is connected to the angle transmission bar 42 of the angle transmission device 4C.
