DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] Example:
[0022] See also Figure 1-Figure 6 , the utility model provides a technical solution:
[0023] A casement door and window limiting device comprises a door frame body 1, the outer side of the door frame body 1 is rotatably connected to a window sash 2, and a connecting groove 3 is provided at one end of the door frame body 1 close to the window sash 2, a connecting piece 4 is rotatably connected inside the connecting groove 3, a receiving groove 5 is provided inside the connecting groove 3, a plurality of groups of limiting racks 6 are fixedly connected on both sides of the receiving groove 5, and a limiting rod 7 is slidably connected inside the receiving groove 5, a rotating block 8 is fixedly connected to one end of the limiting rod 7 away from the receiving groove 5, and an end of the rotating block 8 away from the limiting rod 7 is rotatably connected to the window sash 2, and the limiting rod 7 extends to the inside of the receiving groove 5 and is rotatably connected to a rotating piece 10.
[0024] Furthermore, the internal structure size of the accommodating groove 5 is designed to correspond to the external structure size of the limiting rod 7. The rotating block 8 is slidably connected to the accommodating groove 5 through the limiting rod 7. The accommodating groove 5 and the limiting rod 7 are slidably connected, so that the limiting rod 7 can be slidably connected to the connecting member 4, thereby enabling the rotating block 8 to be slidably connected to the connecting member 4. When the connecting member 4 is displaced, its displacement stability can be increased.
[0025] Among them, the internal structure size of the connecting groove 3 is designed to correspond to the external structure size of the connecting piece 4. The door frame body 1 is connected to the connecting piece 4 through the connecting groove 3. The connecting piece 4 is connected to the connecting groove 3 so that the connecting piece 4 can be connected to the door frame body 1. When the window sash 2 and the door frame body 1 are closed, the connecting groove 3 can be stored inside it through the connecting groove 3, thereby preventing the closing of the window sash 2 and the door frame body 1 from being affected.
[0026] Secondly, both ends of the rotating member 10 near the two sets of limit racks 6 are fixedly connected with fixed rods 11. The external structure size of the fixed rod 11 is designed to correspond to the internal structure size of the limit rack 6. The rotating member 10 is connected to the limit rack 6 through the fixed rod 11. The fixed rod 11 is connected to the limit rack 6 so that the rotating member 10 can be connected to the limit rack 6. When the limit rod 7 drives the rotating block 8 to move, the limit rod 7 can be connected through the limiting connection between the fixed rod 11 and the limit rack 6. When the window sash 2 is opened and closed, its stability can be increased to prevent displacement.
[0027] Furthermore, the top of the connecting member 4 is slidably connected with a sleeve 12, and the inside of the sleeve 12 is slidably connected with a moving rod 13, and the sleeve 12 is rotatably connected to the rotating member 10 through the moving rod 13, and the outside of the moving rod 13 is fixedly connected to a limiting block 14 located inside the sleeve 12, and a compression spring 15 is sleeved on the top of the limiting block 14 and located on the outside of the moving rod 13. When the window sash 2 needs to be opened and closed, the moving rod 13 is pulled to drive the rotating member 10 to rotate, so that the fixed rod 11 can be moved out from the inside of the limiting rack 6, so that the limiting rod 7 can be displaced, driving the rotating block 8 to be displaced, so The window sash 2 can be opened and closed. When the window sash 2 is opened and closed, the moving rod 13 is released, and the limit block 14 is driven to move by the compression spring 15, so that the moving rod 13 can move, drive the rotating member 10 to rotate, and the fixed rod 11 is clamped in the inside of the limit rack 6. The limit rack 6 can limit the limit rod 7, so that the range of the opening angle can be freely adjusted, which is convenient for use. The limiting connection between the fixed rod 11 and the limit rack 6 can prevent the opened window sash 2 from being passively closed under the action of wind in windy weather, resulting in poor user experience and insufficient humanization.
[0028] Furthermore, the ends of the door frame body 1 and the window sash 2 that are close to each other are rotatably connected with a rotating rod 16, and the two sets of rotating rods 16 are rotatably connected. The two sets of rotating rods 16 are rotatably connected to each other, so that the window sash 2 can increase its stability when opening and closing to prevent deviation.
[0029] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the window sash 2 needs to be opened and closed, the moving rod 13 is pulled to drive the rotating member 10 to rotate, so that the fixed rod 11 can be displaced from the inside of the limiting rack 6, so that the limiting rod 7 can be displaced, driving the rotating block 8 to be displaced, so that the window sash 2 can be opened and closed. When the window sash 2 is opened and closed, the moving rod 13 is released, and the limiting block 14 is driven to be displaced by the compression spring 15, so that the moving rod 13 can be displaced, driving the rotating member 1 0 is rotated, and the fixing rod 11 is clamped in the inside of the limiting rack 6. The limiting rack 6 can limit the limiting rod 7, so that the range of the opening angle can be freely adjusted, which is convenient for use. The limiting connection between the fixing rod 11 and the limiting rack 6 can prevent the opened window sash 2 from being passively closed under the action of wind in windy weather, resulting in poor user experience and insufficient humanization. Compared with the existing casement door and window limiting device, the utility model can improve the overall practicality of the casement door and window limiting device through design.
