Description

Technical Field

[0001] The present invention relates to the technical field of windows, and in particular to an inward-opening system window with thermal insulation and heat-insulating aluminum alloy multi-dimensional protection. Background Art

[0002] Aluminum alloy doors and windows refer to those made with aluminum alloy extruded profiles for frames, stiles, and sashes. These include those with aluminum alloy as the base material for load-bearing members (members that bear and transmit deadweight and loads), and those made of wood or plastic, also known as aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows. Inward-opening system windows, in other words, windows whose sashes open toward the interior.

[0003] In the prior art, when an inward-opening system window is opened toward the interior, the window sash needs to remain fixed after rotating to a certain angle and will not rotate on its own. Therefore, a limiter is required to limit the opening angle of the window sash. In other words, the limiter will limit the window sash when it is flipped to a fixed angle to prevent the window sash from rotating on its own. For example, patent publication number CN117418756 A discloses a magnetic limiter for an inward-opening casement window, which includes a door frame body and a window body, and also includes: a rotation opening mechanism for rotating the window body to open it. The rotation opening mechanism is located on the window body. The beneficial effect is that by providing the rotation opening mechanism on the handle of the window body, according to the action of rotating the handle, the attraction between the two magnets is removed when the window body is opened, thereby reducing the difficulty of the user to open the window body. The two magnets lose their attraction. Correspondingly, when the window body is opened, the friction between the two magnets is reduced, reducing the damage between the two magnets caused by the friction, thereby increasing the service life of the two magnets and improving the effect of the attraction between the two magnets on closing the window body.

[0004] However, the limiter of the above structure can only limit the window sash when it is rotated to a certain angle, which has obvious shortcomings in actual use. The limiter of the above structure can only limit the window sash when it is rotated to a specific angle. However, in real life, users have diverse requirements for the opening angle of window sashes. They often need to open the window sash to multiple different angles according to different ventilation needs, lighting needs, or space utilization needs. The limiter involved in this patent obviously cannot meet such diverse opening angle requirements, greatly limiting the flexibility and convenience of the inward-opening system window in actual use, and cannot well meet the actual usage needs of users. Summary of the Invention

[0005] The object of the present invention is to provide an inward-opening system window with thermal insulation, heat-insulating broken-bridge aluminum alloy and multi-dimensional protection to solve the problems raised in the above-mentioned background technology.

[0007] Furthermore, the extrusion assembly includes a cylindrical portion fixed to the upper end face of the limit seat, the cylindrical portion is provided with an inner cavity, and a sliding block is mounted in the inner cavity, the sliding block slides freely in the inner cavity, the end face of the sliding block is fixed with a connecting rod, the lower end of the connecting rod slides into the limit seat and is fixed with an extrusion block, the limit seat is provided with a slot for the extrusion block to engage, and the extrusion block slides freely in the slot, the cylindrical portion is provided with a damping unit, and the damping unit is used to adjust the extrusion force of the extrusion block on the surface of the protrusion.

[0008] Furthermore, the damping unit includes an adjusting bolt with a vertical thread passing through the cylindrical portion, and a pressure block is fixed to one end of the adjusting bolt passing through the inner cavity. An elastic member is provided between the pressure block and the sliding block, and the elastic member elastically presses against the sliding block and gives the sliding block potential energy to move downward.

[0009] Furthermore, the elastic member is a spring arranged in the inner cavity, and the two ends of the spring in the elastic force direction elastically press against the sliding block and the pressing block respectively.

[0010] Furthermore, the pressing block is made of brass.

[0011] Furthermore, a dead stop is fixedly connected to one end of the limit rod away from the window sash, and the dead stop is used to limit the movement of the limit rod toward the window sash.

[0012] Furthermore, a short shaft is vertically fixed to the lower surface of the limiting seat, and the short shaft slidably penetrates the bottom frame and is rotatably connected to the fixing seat.

[0013] Furthermore, a floating part is snap-fitted and installed in the bottom frame. The floating part slides freely up and down in the bottom frame and a damping strip mounting part is fixedly connected to the upward side. A through groove is provided on the upward side of the bottom frame for the damping strip mounting part to pass freely. A damping strip is embedded in the top of the damping strip mounting part, and the short shaft is provided with a lifting assembly. The lifting assembly is used to drive the limit seat to rotate by the limit rod after the window sash is closed, thereby driving the floating part to move upward, so that the damping strip abuts the bottom surface of the window sash, thereby generating a damping force for closing the window sash.

[0014] Furthermore, the lifting assembly includes a fixed sleeve fixedly sleeved on the lower end of the short shaft and located in the hollow part of the bottom frame, the periphery of the fixed sleeve is horizontally fixed with a swing arm, the bottom frame is provided with a clearance groove for the swing arm to pass freely, the wall surface of the floating part is provided with a through groove for the swing arm to pass freely, and the top wall of the through groove is fixed with a protrusion extending downward.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, an extrusion assembly is provided to generate an extrusion force on the surface of the protrusion. When the window sash is opened and flipped, the protrusion contacts the extrusion assembly, and the damping of the window sash flipping increases rapidly, so that the window sash does not rotate on its own. As a result, the window sash can be fixed at multiple flipping angles when flipping, meeting the demand for multi-angle rotation and opening of the window sash. 2. In the present invention, when the window sash is closed, the limit rod drives the limit seat to rotate, so that the limit seat rotates to a fixed position. During the rotation of the limit seat, the lifting assembly is triggered to drive the floating portion to move upward, thereby exposing the damping strip to the surface of the bottom frame. When the window sash is closed, the upper surface of the damping strip scrapes against the bottom surface of the window sash, thereby increasing the damping force of the window sash closing. As a result, after the window sash is closed, the bottom surface of the window sash and the surface of the bottom frame are in tighter contact, thereby preventing the window sash from loosening when blown by wind. In addition, the damping strip can, to a certain extent, increase the sealing degree between the bottom surface of the window sash and the surface of the bottom frame, thereby reducing the infiltration of rainwater. 3. In the present invention, an adjusting bolt is provided to drive the pressing block to move downward, so that the degree of compression of the pressing block on the spring can be adjusted, and then the elastic supporting force of the spring on the sliding block can be adjusted, thereby adjusting the compression force of the pressing block on the protrusion.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-10The present invention provides: an inward-opening system window with thermal insulation and heat-insulating broken bridge aluminum alloy multi-dimensional protection, comprising a window frame 1 and a window sash 4 made of broken bridge aluminum alloy, a movable hinge is installed on one side of the window sash 4, so that the window sash 4 is hinged to the window frame 1, and the window sash 4 rotates towards the indoor direction, a sealing strip 5 is installed around the window sash 4, so that after the window sash 4 is closed, the window sash 4 and the window frame 1 surface are sealed, a fixing seat 9 is installed on the upper surface of the bottom frame 2 of the window frame 1 by screws, a bearing is embedded in the fixing seat 9, a short shaft 10 is fixedly installed in the inner ring of the bearing, the short shaft 10 slides through the bottom frame 2, and the upper end of the short shaft 10 is fixedly connected to the limit seat 8, so that the limit seat 8 can rotate and connect Connected to the fixing seat 9, the window sash 4 is hingedly mounted on the side facing the bottom frame 2. The limit rod 3 is arranged horizontally, and the end away from the window sash 4 is inserted into the limit seat 8. The limit rod 3 is fixedly connected to a plurality of protrusions 15 along its length on the upward side. The wall of the limit seat 8 is provided with a sliding groove 14 for the limit rod 3 and the protrusions 15 to pass freely. The upper end surface of the limit seat 8 is fixedly connected to a cylindrical portion 12 extending upward. The cylindrical portion 12 defines an inner cavity, and a sliding block 24 is fixedly mounted in the inner cavity, and the sliding block 24 slides freely in the inner cavity. The end surface of the sliding block 24 is fixedly connected to a connecting rod 25. The lower end of the connecting rod 25 slides into the limit seat 8 and is fixedly connected to an extrusion block 26. The squeezing assembly of the aforementioned structure acts as an active force-applying component, generating a squeezing force that can be adjusted or responsive to the window sash's motion. The protrusion, mounted on the window sash, has a surface shape that matches the squeezing assembly, ensuring reliable contact between the two during the window sash's rotation. As the window sash opens and rotates, the squeezing assembly and the protrusion gradually approach and come into contact. As the window sash continues to rotate, the squeezing assembly applies a squeezing force on the protrusion's surface. This squeezing force generates friction at the contact surface between the protrusion and the squeezing assembly, and this friction increases with increasing squeezing force. Because this friction hinders the window sash's rotational motion, the damping of the window sash's rotation rapidly increases. When the window sash reaches a certain rotation angle, the squeezing force applied by the squeezing assembly on the protrusion reaches a level sufficient to balance the sash's own weight and any external forces (such as wind) that affect the sash's rotation. At this point, the net torque acting on the window sash reaches zero, and the window sash stops rotating, thus achieving a fixed position at that rotation angle. The coordinated design of the squeezing assembly and the protrusion allows this fixed position to be achieved at various rotation angles. When the flip angle of the window sash needs to be changed, it is only necessary to apply sufficient external force to overcome the current friction force so that the window sash continues to flip. When the new angle is reached, the extrusion component and the protrusion will re-form a new equilibrium state and be fixed again.

[0021] The limit seat 8 is provided with a slot for the extrusion block 26 to engage, and the extrusion block 26 slides freely in the slot. The cylindrical part 12 is vertically threaded with an adjusting bolt 13, and one end of the adjusting bolt 13 that penetrates the inner cavity is fixedly connected to a pressure block 22. A spring 23 is provided between the pressure block 22 and the sliding block 24. The spring 23 is provided in the inner cavity, and its two ends in the direction of elastic force elastically press against the sliding block 24 and the pressure block 22 respectively. The spring 23 elastically presses against the sliding block 24 and gives the sliding block 24 potential energy to move downward. The end of the limit rod 3 away from the window sash 4 is fixedly connected to a dead stop 11, and the dead stop 11 is used to limit the movement of the limit rod 3 toward the window sash 4; in this mechanical adjustment structure, by cleverly setting the adjusting bolt, a key component, when a rotation operation is applied to the adjusting bolt, the adjusting bolt will produce axial displacement under the action of the threaded cooperation, thereby driving the pressure block connected to it to move downward. As the pressure block moves downward, the degree to which it squeezes the spring changes. This, in turn, causes the spring's stored elastic potential energy to change accordingly. This allows the spring's elastic resistance to the sliding block to be flexibly adjusted based on actual needs. The sliding block and the pressure block are linked, and changes in the spring's elastic resistance are transmitted to the pressure block, allowing the pressure of the pressure block on the bump to be precisely adjusted to meet the requirements of different working conditions.

[0022] A floating portion 17 is snap-fitted and installed in the bottom frame 2. The floating portion 17 slides freely up and down in the bottom frame 2 and is fixedly connected to a damping strip mounting portion 18 on its upward side. A through groove is provided on the upward side of the bottom frame 2 for the damping strip mounting portion 18 to pass freely. A damping strip 6 is embedded in the top of the damping strip mounting portion 18. A fixed sleeve 16 is fixedly sleeved on the lower end of the short shaft 10, and the fixed sleeve 16 is located in the hollow part of the bottom frame 2. A swing arm 21 is fixedly connected to the horizontal periphery of the fixed sleeve 16. The bottom frame 2 is provided with an air-avoidance groove for the swing arm 21 to pass freely. A through groove 20 is provided on the wall surface of the floating portion 17 for the swing arm 21 to pass freely. A downwardly extending protrusion 19 is fixedly connected to the top wall of the through groove 20. A tension spring 7 is provided in the hollow part of the bottom frame 2, and the two ends of the tension spring 7 are respectively fixed to the floating portion 17 and the inner wall of the bottom frame 2.

[0023] The working principle of this embodiment is as follows: By rotating the adjusting bolt 13, the adjusting bolt 13 is threadedly engaged with the cylindrical portion 12, and the adjusting bolt 13 can drive the pressure block 22 to move downward, so that the pressure block 22 compresses the spring 23. The spring 23 accumulates elastic potential energy and generates an elastic downward resisting force on the sliding block 24. When the window sash 4 is rotated toward the room, after it is opened to a suitable angle, the surface of one of the protrusions 15 contacts the surface of the extrusion block 26. The spring 23 exerts a force on the sliding block 24, which causes the extrusion block 26 to generate a large extrusion force on the surface of the protrusion 15, thereby preventing the window sash 4 from rotating on its own. When the window sash 4 is closed, the rotation of the window sash 4 will drive the limit rod 3 to rotate to a certain extent. The limit rod 3 will drive the limit seat 8 to rotate (the rotation angle is small), so that the swing arm 21 rotates in the through groove 20. When the window sash 4 rotates toward the outdoors, the swing arm 21 will approach the protrusion 19. When the swing arm 21 contacts the surface of the protrusion 19, it will generate an upward force on the floating part 17, causing the floating part 17 to move upward and expose the damping strip 6 to the surface of the bottom frame 2, so that the bottom surface of the window sash 4 is in contact with the damping strip 6, and a damping force is generated on the bottom surface of the window sash 4. When the floating part 17 moves upward, the tension spring 7 is stretched and accumulates elastic potential energy. When the swing arm 21 is out of contact with the protrusion 19, the tension spring 7 will drive the floating part 17 to move downward.

[0024] During the process: As the window sash slowly closes, the ingenious internal stop rod begins to play a crucial role. Guided by a specialized mechanical structure, the stop rod precisely rotates the connected stop seat. As the stop rod pushes, the stop seat continuously rotates along a predetermined trajectory until it reaches a predetermined fixed position. As the stop seat rotates, it acts as a trigger, cleverly triggering the associated lifting assembly. Upon receiving the trigger signal, the lifting assembly quickly responds and begins to operate. Its internal power transmission mechanism applies an upward force to the floating portion, causing it to slowly move upward. As the floating portion rises, the damping strip, previously hidden within the bottom frame, gradually emerges from the surface of the bottom frame. As the window sash continues to close until it contacts the exposed damping strip, the upper surface of the damping strip scrapes against the underside of the window sash. This scraping is not simply friction; rather, it increases the contact pressure and friction between the two, significantly increasing the damping force applied to the window sash during closing. This ensures that when the window sash is fully closed, the bottom surface of the sash and the bottom frame surface fit tightly together, creating a more secure contact. This secure contact provides strong stability for the window sash, effectively preventing it from shaking or loosening when exposed to wind, which could affect user experience and safety. Furthermore, the damping strip provides an additional sealing effect. It fills the tiny gap between the bottom surface of the window sash and the bottom frame surface, enhancing the seal between the two, significantly reducing rainwater infiltration and providing better protection for the indoor environment.
