Description

Technical Field

[0001] This utility model relates to the field of window technology, specifically a frame and sash structure for an inward-opening door / window. Background Technology

[0002] With the continuous development of the construction industry, inward-opening doors and windows have been widely used in various types of buildings due to their excellent sealing, sound insulation and ventilation effects.

[0003] A Chinese patent with authorization announcement number CN218716406U discloses a frame and sash structure for an inward-opening door and window, including an outer fixed window frame. One end of the outer fixed window frame is connected to a locking block, and the interior of the locking block is connected to an inner fixed window frame through soundproof glass. The other end of the outer fixed window frame of the outer frame is connected to an inner frame sash. The top of the inner frame sash has a connecting groove, and a second inner sash frame is connected to the connecting groove through a snap-fit ​​airtight connecting component. The sealing strength of the connection between the inner frame sash frame and the second inner sash frame is ensured by a convex connecting block and a sealing strip. The second inner sash frame is connected to the sealing strip by a butterfly-shaped protrusion. The butterfly-shaped protrusion has an irregular connecting surface, which helps to fully ensure the airtightness of the connection, thereby strengthening the airtightness of the connection between the second inner sash frame and the sealing strip, thus avoiding heat dissipation and ensuring the thermal insulation effect at the window frame connection.

[0004] However, the above structure still has some problems. In workshops with high dust levels, dust accumulates on the inner surface of windows after long-term use, which affects the overall hygiene of the room. If not dealt with in time, the dust covering the inner surface of the window will reduce the light transmittance and lead to poor indoor lighting. Therefore, a frame and sash structure for inward-opening doors and windows is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a frame and sash structure for an inward-opening door and window.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A frame and sash structure of an in-swing door window of the present utility model includes a window frame. An accommodation groove is provided inside one side of the bottom end of the window frame. A sliding groove is provided inside one side edge of the window frame. One end of the accommodation groove is communicated with the bottom end of the sliding groove and is arranged in an "L" shape. A transverse groove is vertically penetrated through the sliding groove inside the window frame. The transverse groove is opened at the middle position of the sliding groove, and the transverse groove and the sliding groove cooperate with each other to form a Chinese character shape. One end of the transverse groove penetrates through one side of the window frame. A connecting rod is slidably penetrated and installed inside the transverse groove. A rolling ball is assembled inside the sliding groove at the middle end of the connecting rod. A support rod is installed at the bottom side of the rolling ball. A cleaning brush is installed at the bottom end of the support rod. When the cleaning brush is not in operation, it is assembled inside the accommodation groove.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-3 As shown, a frame and sash structure of an inward-opening casement window includes a window frame 1. An internal placing groove 2 is opened at one side of the bottom end of the window frame 1. An internal sliding groove 3 is opened at the edge of one side of the window frame 1. One end of the placing groove 2 is communicated with the bottom end of the sliding groove 3, showing an "L" shape. A horizontal groove 4 is vertically penetrated through the sliding groove 3 inside the window frame 1. The horizontal groove 4 is opened at the middle position of the sliding groove 3, and the horizontal groove 4 and the sliding groove 3 cooperate with each other to form a Chinese character shape, and one end of the horizontal groove 4 penetrates through one side of the window frame 1. A connecting rod 5 is slidably penetrated and installed inside the horizontal groove 4. A rolling ball 6 is assembled inside the sliding groove 3 at the middle end of the connecting rod 5. A support rod 7 is installed at the bottom side of the rolling ball 6. A cleaning brush 8 is installed at the bottom end of the support rod 7. When the cleaning brush 8 is not working, it is assembled inside the placing groove 2. One end of the connecting rod 5 is installed with a handle 9 at one side of the window frame 1;

[0024] When the cleaning brush 8 is working, the support rod 7 is perpendicular to the window frame 1. When the cleaning brush 8 is not working, the support rod 7 is parallel to the window frame 1;

[0025] A side door 22 is hinged to one side of the window frame 1, located at the position of the placement groove 2 and the sliding groove 3. The side door 22 is L-shaped, and a fixing buckle 23 is installed at one end of the side door 22. During operation, in a dusty workshop, after long-term use, dust accumulates on the inner surface of the window 12, affecting the overall cleanliness of the room. If not cleaned in time, the dust covering the inner surface of the window 12 will reduce light transmittance, resulting in poor indoor lighting. When the cleaning brush 8 is not in operation, the support rod 7 is parallel to the window frame 1, and the cleaning brush 8 is located in the placement groove 2. At this time, since the placement groove 2 and the sliding groove 3 are connected in an "L" shape, and the side door 22 is closed, the cleaning brush 8 is protected from dust accumulation, and space is also saved. When using the cleaning brush 8, open the side door 22 through the fixing buckle 23. By turning the handle 9, the connecting rod 5 and the rolling ball 6 will rotate in the four sliding grooves 3 of the horizontal groove, which in turn will drive the support rod 7 to rotate. When the support rod 7 is perpendicular to the window frame 1, the cleaning brush 8 is in an operable state. Then, push the handle 9 up and down to make the connecting rod 5 slide in the horizontal groove 4 and the rolling ball 6 move in the sliding groove 3. The connecting rod 5 drives the cleaning brush 8 to move up and down along the sliding groove 3 on one side of the window 12, thereby cleaning the inner surface of the window 12. After cleaning, move the cleaning brush 8 to the bottom of the window frame 1, turn the handle 9 in the opposite direction to make the support rod 7 return to a state parallel to the window frame 1, put the cleaning brush 8 back into the placement groove 2, and close the side door 22.

[0026] Please see Figure 1 , 2 As shown in Figures 4 and 5, an installation groove 10 is provided inside one side of the window frame 1. A rotating shaft 11 is rotatably installed between the two sides of one end edge of the installation groove 10. A window 12 is installed on the outside of the rotating shaft 11. A handle is fitted on one side of the window 12.

[0027] A connecting rod 13 is mounted on one bottom end of the window 12 via a pin. The mounting groove 10 has an upward-opening convex groove 14 inside, and a sliding block 15 is slidably mounted inside the convex groove 14. One end of the connecting rod 13 is mounted on the top side of the sliding block 15 via a pin.

[0028] A side groove 16 is formed inside one side of the bottom end of the window frame 1. The side groove 16 is connected to one side of the convex groove 14. One end of the sliding block 15 is slidably installed inside the side groove 16. A through hole 17 is formed inside one side of the sliding block 15, located on one side of the side groove 16. A limit rod 18 is slidably installed inside the through hole 17. A limit block 19 is installed at one end of the limit rod 18. A tension spring 20 is fixedly connected between the limit block 19 and the sliding block 15. The tension spring 20 is sleeved on... On the outside of the limiting rod 18, several limiting holes 21 are equidistantly provided inside one side of the window frame 1. The other end of the limiting rod 18 passes through one of the limiting holes 21. During operation, with the continuous development of the construction industry, inward-opening doors and windows have been widely used in various buildings due to their good sealing, sound insulation, and ventilation effects. When it is necessary to open the window 12, hold the handle of the window 12 and open the window 12 inward with the rotating shaft 11 as the axis. During the opening of the window 12, the connecting rod 13 moves accordingly. The opening of the window 12 drives the connecting rod 13 to push the sliding block 15 to move in the convex groove 14 and the side groove 16, so that the window 12 can move stably within a certain range, ensuring the stability and safety of opening. When the window 12 is opened to the appropriate position, the tension spring 20 is in the tension state, and the limiting rod 18 disengages from the limiting hole 21. When the sliding block 15 moves to the appropriate position, the other end of the limiting rod 18 will pass through one of the limiting holes 21 under the elastic force of the tension spring 20. This fixes the sliding block 15, thereby fixing the opening position of the window 12 and preventing the window 12 from closing due to accidental contact. To change the opening position of the window 12, simply pull the limiting block 19 and the limiting rod 18 outward to overcome the elastic force of the tension spring 20, causing the limiting rod 18 to disengage from the current limiting hole 21. Then, adjust the opening angle of the window 12. After the sliding block 15 moves to the new position, the limiting rod 18 will be locked back into the corresponding limiting hole 21 under the action of the tension spring 20, thus fixing the new position.

[0029] Working principle: When window 12 needs to be opened, hold the handle of window 12 and open it inwards around the rotating shaft 11. During the opening process, the connecting rod 13 moves accordingly. The opening of window 12 drives the connecting rod 13 to push the sliding block 15 to move within the convex groove 14 and the side groove 16, thereby enabling window 12 to move stably within a certain range, ensuring the stability and safety of opening. When window 12 is opened to the appropriate position, the tension spring 20 is in the tension state, and the limiting rod 18 disengages from the limiting hole 21. When the sliding block 15 moves to the appropriate position, the limiting rod 18... Under the elastic force of the tension spring 20, its other end will pass through one of the limiting holes 21, thereby fixing the sliding block 15 and fixing the opening position of the window 12, preventing the window 12 from closing due to accidental contact. If the opening position of the window 12 needs to be changed, simply pull the limiting block 19 and the limiting rod 18 outward to overcome the elastic force of the tension spring 20, so that the limiting rod 18 disengages from the current limiting hole 21. Then adjust the opening angle of the window 12. After the sliding block 15 moves to the new position, the limiting rod 18 will be locked into the corresponding limiting hole 21 again under the action of the tension spring 20, thus fixing the new position.

[0030] When the cleaning brush 8 is not in use, the support rod 7 is parallel to the window frame 1, and the cleaning brush 8 is located in the placement groove 2. At this time, since the placement groove 2 and the slide 3 are connected in an "L" shape and the side door 22 is closed, the cleaning brush 8 is protected from dust and also saves space. When the cleaning brush 8 needs to be used, the side door 22 is opened by the fixing buckle 23. By turning the handle 9, the connecting rod 5 and the rolling ball 6 are driven to rotate in the slide 3 of the horizontal groove 4, which in turn drives the support rod 7 to rotate. When the support rod 7 is perpendicular to the window frame 1, the cleaning brush 8 is in the working state. Then, the handle 9 is pushed up and down, so that the connecting rod 5 slides in the horizontal groove 4 and the rolling ball 6 moves in the slide 3. The connecting rod 5 drives the cleaning brush 8 to move up and down along the slide 3 on one side of the window 12, thereby realizing the cleaning operation of the inner surface of the window 12. After cleaning, the cleaning brush 8 is moved to the bottom of the window frame 1. The handle 9 is turned in the opposite direction to make the support rod 7 return to the parallel state with the window frame 1. The cleaning brush 8 is put back into the placement groove 2 and the side door 22 is closed.
