Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] As shown in the attached diagram, this utility model discloses a side-pressure upper wheel for a door / window with a buffer function, comprising a side-pressure upper wheel 2. The side-pressure upper wheel 2 includes a base 21 mounted on a sliding sash and a sliding member 22 slidably connected to the base 21. The corner mechanism 1 is connected to the sliding member 22 via a transmission rod. A horizontal pulley is also provided on the top of the sliding member 22. This is a structure of existing side-pressure doors and windows. It should be noted that it also includes a damper 3 and a trigger clip 4. The trigger clip 4 is mounted on the outer frame and can adopt an existing structure. The damper 3 is set on the sliding member 22 and includes a housing 31, an auxiliary telescopic rod 32, and a movable member 33. Figure 1-3 As shown, the outer shell 31 is composed of two connecting plates, which are fixedly connected to each other. There is a space between the two connecting plates for installing structures such as the assist telescopic rod 32 and the movable part 33. One side of the outer shell 31 is provided with a guide groove 310 for the movable part 33 to slide. The end of the guide groove 310 away from the sliding part 22 is bent downward. The resistance telescopic rod is composed of a fixed part 322 and a telescopic section 321, which can be implemented by a pneumatic spring, etc. The telescopic section 321 of the assist telescopic rod 32 is installed on the other side of the outer shell 31. The sliding part 22 is provided with a through hole 200. The movable part 33 is connected to a push rod 34. The push rod 34 passes through the through hole 200 and is connected to the fixed part 322 of the assist telescopic rod 32. That is, the push rod 34 can slide in the through hole 200 along its axis. One end of the push rod 34 is connected to the fixed part 322, so that the movable part 33 moves while pushing the fixed part 322. To ensure the balance of the sliding sash, existing side-pressure doors and windows are equipped with two side-pressure upper wheels 2 on their upper side. A damper 3 can be installed on the side-pressure upper wheel 2 near the closing end, or both side-pressure upper wheels 2 can be equipped with dampers 3, so that the sliding sash has a buffer function when opening and closing.
[0022] This utility model discloses an upper wheel for a side-pressure door and window with a buffer function. By setting a damper 3 on the upper wheel 2, the damper 3 is installed using a sliding member 22 as a carrier. When closed, the triggering member 4 of the outer frame abuts against and pushes the movable member 33, which pushes the extension rod 32 to extend, thus providing damping before the side-pressure door and window closes. When opened, the triggering member 4 pulls the movable member 33 until the movable member 33 enters the bend of the guide groove 310, thereby releasing the engagement with the triggering member 4. Without affecting the side-pressure system, the side-pressure door and window has a buffer function.
[0023] Specifically, the sliding member 22 is provided with a rotating shaft 202, and the middle part of the outer shell 31 is provided with a round hole rotatably connected to the rotating shaft 202. The movable member 33 is located above the corner device 1, specifically with two connecting plates having round holes, the sliding member 22 being located between the two connecting plates, and connected to the round hole through the rotating shaft 202.
[0024] Specifically, the movable component 33 is rotatably connected to one end of the push rod 34. Specifically, the movable component 33 has a guide rod 333, and one end of the push rod 34 is provided with a rod sleeve. The rod sleeve has a through hole for the guide rod 333 to pass through. The other end of the push rod 34 is connected to the fixing part 322 of the assist telescopic rod 32. The push rod 34 can be directly fixed to the fixing part 322 of the assist telescopic rod 32, or a snap-fit structure can be used for connection. The telescopic section 321 of the assist telescopic rod 32 is located between the fixing part 322 and the sliding component 22, and the telescopic section 321 is rotatably connected... One end of the telescopic section 321 is located inside the fixed part 322, and the telescopic section 321 can slide in and out of the fixed part 322. The other end of the telescopic section 321 is provided with a connector with two rotating shafts. The outer shell 31 has through holes at the corresponding two rotating shafts, so that one end of the telescopic section 321 can be rotatably connected to the outer shell 31. Furthermore, the fixed part 322 of the telescopic rod 32 is provided with a pin. The outer shell 31 is provided with a strip groove. The pin on the fixed part 322 is provided in the strip groove and can slide along the length of the strip groove.
[0025] Specifically, the movable component 33 includes a main body 330, an a-hook portion 331, and a b-hook portion 332. The main body 330 is provided with a guide rod 333 slidably connected to the guide groove 310. The a-hook portion 331 and the b-hook portion 332 are respectively disposed at both ends of the upper side of the main body 330, thereby forming a locking space between the a-hook portion 331 and the b-hook portion 332. This triggers the locking component 4 to enter the locking space and pushes either the a-hook portion 331 or the b-hook portion 332, such as... Figure 4When closed, the trigger 4 pushes the hook 332 (b), and when opened, the trigger 4 pushes the hook 331 (a), causing the main body 330 to slide along the guide groove 310. It should be noted that there are two guide rods 333, respectively positioned below the hook 331 (a) and hook 332 (b), making the sliding of the main body 330 smoother and more stable, while also enhancing the connection strength between the moving part 33 and the outer shell 31. The main body 330 is provided with a through groove 3300, and the a... The hook part 331 is slidably disposed in the through groove 3300, that is, the hook part 331 can extend and retract in the through groove 3300. An elastic element 334 is disposed within the main body 330, abutting against the hook part 331. One end of the elastic element 334 abuts against the hook part 331, and the other end abuts against the main body 330, ensuring that after the hook part 331 is pushed back into the through groove 3300 by the triggered locking element 4, the hook part 331 can be reset instantly upon loss of force. The sides of hooks 31 and 332 that are far apart from each other are inclined surfaces. During the opening process, the trigger clip 4 enters the clip space and abuts against hook 331. When the push-pull fan is manually pushed, the trigger clip 4 pushes hook 331 towards the bend. The movable part 33 pulls the push rod 34. When the push rod 32 loses the push force of the push rod 34, it gradually retracts and returns to its original state, that is, the fixed part 322 moves towards the bend. Finally, the movable part 33 enters the bend of the guide groove 310, thereby causing the trigger clip 4 to disengage from the clip space. When closing, the movable part 33 located at the bend of the guide groove 310 cooperates with the trigger clip 4. The trigger clip 4 pushes hook 332 to move, thereby causing the movable part 33 to push the fixed part 322 of the push rod 34 away from the bend, lengthening the push rod 32. The push rod 32 provides damping for closing.
[0026] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
