Description

Technical Field

[0001] This utility model relates to the field of system window technology, specifically to an inward-opening micro-ventilation system window. Background Technology

[0002] A micro-ventilation system window is a window design that achieves gentle ventilation by opening the window at a small angle. It typically has a slender ventilation fan on the side or sides of the window, with a small opening width, generally around 10 centimeters. It can open inward or tilt inward. This design causes the wind to be partially blocked as it passes through the glass, preventing it from blowing directly on people and thus reducing the risk of catching a cold.

[0003] However, existing micro-ventilation system windows, when opened for ventilation, lack a limiting structure, making it difficult to adjust and fix the opening angle. When the wind is too strong, the window opening will increase, making it inconvenient for users to ventilate. Furthermore, a larger opening during ventilation reduces safety. Utility Model Content

[0004] The purpose of this utility model is to provide an inward-opening micro-ventilation system window, which is simple and convenient to operate, improves safety, and allows for flexible adjustment of the opening and closing angle, making it easy to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an inward-opening micro-ventilation system window, comprising a frame, a partition fixedly connected to the inner side of the frame, a fixed window and a ventilation window respectively provided at both ends of the partition, the ventilation window comprising a window sash rotatably connected to the side of the frame via a hinge, a base fixedly connected to the bottom inner side of the frame, a cavity formed in the lower interior of the base, a sliding groove formed in the upper interior of the base communicating with the cavity and having its top end communicating with the outside, a limit block provided inside the cavity, a screw fixedly connected to the upper end face of the limit block, the screw penetrating the base through the sliding groove, a rotating seat provided on the upper end face of the base, a threaded groove formed at the bottom end of the rotating seat, the rotating seat being threadedly connected to the outer wall of the screw through the threaded groove, a collar slidably sleeved below the outer wall of the screw, a first connecting rod fixedly connected to the outer wall of the collar, a second connecting rod rotatably connected to the other end of the first connecting rod, a hinge fixedly connected to the outer wall of the window sash, and the other end of the second connecting rod rotatably connected to the window sash through the hinge.

[0006] To ensure that the limiting block can only move in the vertical direction, in a preferred embodiment of the internally opening micro-ventilation system window of this utility model, mounting grooves are provided on both the left and right sides of the inner wall of the cavity, and sliding rods are fixedly connected inside the two mounting grooves. Sliding blocks are slidably connected to the outer walls of the two sliding rods, and the two sliding blocks are fixedly connected to the limiting block.

[0007] To facilitate the rotation of the rotating base, a knob is fixedly connected to the upper end face of the rotating base, which is a preferred embodiment of the inward-opening micro-ventilation system window of this utility model.

[0008] To facilitate fixing the base, in a preferred embodiment of the inward-opening micro-ventilation system window of this utility model, two symmetrically arranged fixing plates are fixedly connected to the lower outer wall of the base, and fixing bolts are threadedly connected to the outer wall of the fixing plates.

[0009] To facilitate the movement of the first connecting rod, as a preferred embodiment of the inward-opening micro-ventilation system window of this utility model, an arc-shaped groove is provided on one side of the outer wall of the base, and the first connecting rod passes through the base through the arc-shaped groove.

[0010] To facilitate the folding of the first and second connecting rods after the window sash is closed, the first connecting rod, as a preferred embodiment of the inward-opening micro-ventilation system window of this utility model, has an "L"-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] After opening the window sash to the designated angle, rotate the rotating base using the knob. Because the threaded groove at the bottom of the rotating base is threadedly connected to the screw, rotating the rotating base causes the screw to move upward. The screw further moves the limiting block upward, and the limiting block presses and fixes the collar between the limiting block and the top of the cavity, thus fixing the collar and preventing it from rotating further. This also fixes the first connecting rod, achieving the limitation of the window sash. Therefore, when the window sash is opened to a certain angle, it can be fixed by rotating the rotating base. The operation is simple and convenient, improves safety, and allows for flexible adjustment of the opening and closing angle, making it easy to use. Attached Figure Description

[0017] Please see Figures 1 to 3 A type of inward-opening micro-ventilation system window includes a frame 1. A partition 3 is fixedly connected to the inner side of the frame 1. A fixed window 2 and a ventilation window 4 are respectively provided at both ends of the partition 3. The ventilation window 4 includes a window sash 6 rotatably connected to the side of the frame 1 via a hinge 5. A base 7 is fixedly connected to the bottom inner side of the frame 1. A cavity 8 is formed in the lower part of the interior of the base 7. A sliding groove 9 is formed in the upper part of the interior of the base 7, communicating with the cavity 8 and with its top end communicating with the outside. A limit block 10 is provided inside the cavity 8. A screw 11 is fixedly connected to the upper end face of the limit block 10. The screw 11 passes through the base 7 through the sliding groove 9. The upper end of the base 7 is provided with a rotating seat 12. The bottom end of the rotating seat 12 is provided with a threaded groove 13. The rotating seat 12 is threaded to the outer wall of the screw 11 through the threaded groove 13. A collar 14 is slidably sleeved below the outer wall of the screw 11. The outer wall of the collar 14 is fixedly connected to a first connecting rod 15. The other end of the first connecting rod 15 is rotatably connected to a second connecting rod 16. The outer wall of the window sash 6 is fixedly connected to a hinge seat 17. The other end of the second connecting rod 16 is rotatably connected to the window sash 6 through the hinge seat 17.

[0018] In this embodiment, the ventilation window 4 includes a window sash 6 that is rotatably connected to the side of the frame 1 via a hinge 5. When the window sash 6 is opened, it opens inward to facilitate micro-ventilation. When the window sash 6 moves, the first connecting rod 15 and the second connecting rod 16 move accordingly. After the window sash 6 is opened to a specified angle, the rotating seat 12 is rotated by the knob 21. Since the threaded groove 13 at the bottom of the rotating seat 12 is threadedly connected to the screw 11, rotating the rotating seat 12 drives the screw 11 to move upward. The screw 11 further drives the limiting block 10 to move upward. The limiting block 10 presses and fixes the collar 14 between the limiting block 10 and the top of the cavity 8, thereby fixing the collar 14 so that it can no longer rotate. This also fixes the first connecting rod 15, thus limiting the window sash 6. Therefore, when the window sash 6 is opened to a certain angle, the window sash 6 can be fixed by rotating the rotating seat 12. The operation is simple and convenient, improves safety, and allows for flexible adjustment of the opening and closing angle, making it easy to use.

[0019] As a technical optimization of this utility model, the inner wall of the cavity 8 is provided with mounting grooves 18 on both the left and right sides. The interior of each mounting groove 18 is fixedly connected with a sliding rod 19. The outer wall of each sliding rod 19 is slidably connected with a slider 20. Both sliders 20 are fixedly connected to the limiting block 10.

[0020] In this embodiment, the slider 20 and the slider rod 19 are slidably connected, and the slider 20 is fixedly connected to the limiting block 10. Therefore, the limiting block 10 can only move up and down in the vertical direction, which facilitates its limiting.

[0021] As a technical optimization of this utility model, a knob 21 is fixedly connected to the upper end face of the rotary base 12.

[0022] In this embodiment, a knob 21 is fixedly connected to the upper end face of the rotary base 12, so that the rotary base 12 can be rotated by the knob 21.

[0023] As a technical optimization of this utility model, two symmetrically arranged fixing plates 22 are fixedly connected to the lower outer wall of the base 7, and fixing bolts are threadedly connected to the outer wall of the fixing plates 22.

[0024] In this embodiment, the base 7 is easily fixed to the inside of the frame by means of the fixing plate 22 and the fixing bolt.

[0025] As a technical optimization of this utility model, an arc-shaped groove 23 is provided on one side of the outer wall of the base 7, and the first connecting rod 15 passes through the base 7 through the arc-shaped groove 23.

[0026] In this embodiment: by setting an arc-shaped groove 23, the first connecting rod 15 can extend to the outside of the base 7, and the opening range of the arc-shaped groove 23 is the range of motion of the first connecting rod 15.

[0027] As a technical optimization of this utility model, the first connecting rod 15 has an "L" shaped structure.

[0028] In this embodiment, the first connecting rod 15 has an "L" shape, which makes it easy to fold the first connecting rod 15 and the second connecting rod 16 after the window sash 6 is completely closed.

[0029] Working principle: The ventilation window 4 includes a window sash 6 that is rotatably connected to the side of the frame 1 via a hinge 5. When the window sash 6 is opened, it opens inward to facilitate micro-ventilation. When the window sash 6 moves, the first connecting rod 15 and the second connecting rod 16 move accordingly. After the window sash 6 is opened to a specified angle, the rotating seat 12 is rotated by the knob 21. Since the threaded groove 13 at the bottom of the rotating seat 12 is threadedly connected to the screw 11, rotating the rotating seat 12 drives the screw 11 to move upward. The screw 11 further drives the limiting block 10 to move upward. The limiting block 10 presses and fixes the collar 14 between the limiting block 10 and the top of the cavity 8, thereby fixing the collar 14 so that it can no longer rotate. This also fixes the first connecting rod 15, thus limiting the window sash 6. Therefore, when the window sash 6 is opened to a certain angle, the window sash 6 can be fixed by rotating the rotating seat 12. The operation is simple and convenient, improves safety, and allows for flexible adjustment of the opening and closing angle, making it easy to use.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
