Description

Technical Field

[0001] This utility model belongs to the technical field of positionable sliding doors and windows, and particularly relates to a positionable sliding door and window. Background Technology

[0002] Positionable sliding doors and windows are an upgraded version of traditional sliding doors and windows with the addition of a positioning mechanism. This allows the door and window sashes to be fixed in any position during the sliding process, rather than being limited to stopping at both ends of the track. This balances ventilation adjustment and safety. Its core advantage is that it solves the limitation of traditional sliding windows that are "either fully open or fully closed" by using special components to achieve on-demand fixing.

[0003] Traditional sliding doors and windows with fixed mounting points present significant inefficiencies in glass replacement if the glass breaks after prolonged use. The process requires locating the retaining strips that hold the glass in place; these strips, typically made of plastic or aluminum alloy, are fastened to the frame via clips. The procedure involves gently prying the strips with a utility knife and then manually peeling them off the frame. Only after all four strips are removed can the broken glass be replaced. After replacement, the strips must be reinstalled one by one. This entire process is time-consuming and fails to provide a quick solution for glass replacement.

[0004] To address this issue, some positionable sliding doors and windows employ a snap-on glass fixing structure. However, this still doesn't completely solve the efficiency problem. The specific operating principle is as follows: First, observe the sash frame around the glass and locate the plastic snaps with small protrusions or press marks. These snaps are usually distributed in 2-3 locations on each side, and their positions are even. Then, pinch the protrusion of the snap with your fingers, gently press it outwards towards the glass, and pry it up or down to dislodge the snap from the slot. After all the snaps have been removed, hold both sides of the glass and gently push it outwards to remove the glass from the sash frame. However, this method requires disassembling several snaps one by one, which still results in slow glass replacement speed and affects the efficiency of glass replacement. Therefore, we propose a positionable sliding door and window. Utility Model Content

[0005] The purpose of this utility model is to provide a positionable sliding door / window to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a positionable sliding door and window, including a frame and two glass door frames, wherein the two glass door frames are disposed within the frame, comprising:

[0007] Two mounting slots are provided, which are located inside the glass door frame and connected to the outside. Glass is inserted into each of the two mounting slots. A slot connected to the outside is provided on the inner wall of the mounting slot. A limiting plate is inserted into the slot and is in contact with the glass.

[0008] Several limiting grooves are respectively formed on two limiting plates;

[0009] A plurality of rotating grooves are respectively opened in two glass door frames and are respectively connected to a plurality of limiting grooves. Each of the plurality of rotating grooves is rotatably connected to a limiting block, and the limiting block is located in the limiting groove and rotatably connected to the limiting groove.

[0010] Two drive components are located within two glass door frames and are used to drive the corresponding number of limit blocks to rotate.

[0011] This technical solution ensures that users can quickly replace the glass, improving the efficiency of glass replacement.

[0012] In the above technical solution, the driving component further includes:

[0013] Several first gear slots are formed inside the glass door frame and are respectively connected to several rotating slots. Each of the several first gear slots is rotatably connected to a first bevel gear and a second bevel gear, and the first bevel gear and the second bevel gear mesh with each other. One end of each of the several first bevel gears extends into the several rotating slots and is respectively fixedly connected to several limiting blocks.

[0014] Two connecting slots are formed inside the glass door frame and are respectively connected to several first gear slots. A first connecting rod is rotatably connected in each of the two connecting slots, and the two ends of the two first connecting rods extend into several first gear slots and are respectively fixedly connected to several second bevel gears.

[0015] Two second gear slots are formed inside the glass door frame, and the two second gear slots are respectively connected to two of the first gear slots. A third bevel gear and a fourth bevel gear are rotatably connected in each of the two second gear slots, and the third bevel gear and the fourth bevel gear mesh with each other. One end of each of the two third bevel gears extends into one of the two first gear slots and is fixedly connected to one end of each of the two first connecting rods. A second connecting rod is fixedly connected between the two fourth bevel gears.

[0016] The fifth bevel gear is rotatably connected in one of the second gear slots and meshes with one of the fourth bevel gears. A rotating rod is fixedly connected to the fifth bevel gear, and one end of the rotating rod passes through the inner wall of one of the second gear slots and extends to the outside.

[0017] A fixing component is located on the rotating rod and is used to fix the rotating rod.

[0018] In this technical solution, it is ensured that the user can drive several limit blocks to rotate simultaneously.

[0019] In the above technical solution, the fixing component further includes:

[0020] A threaded groove is formed on the periphery of the rotating rod. A threaded sleeve is threadedly connected to the threaded groove and is located on one side of the glass door frame. The periphery of the threaded sleeve is provided with anti-slip texture.

[0021] In this technical solution, the rotating rod is ensured to rotate without being affected by external factors, thus improving the overall stability of the device.

[0022] In the above technical solution, one end of the first bevel gear is rotatably connected to the rotating groove, the two ends of the two first connecting rods are respectively rotatably connected to a plurality of first gear grooves, and one end of the third bevel gear is rotatably connected to one of the first gear grooves.

[0023] In this technical solution, it is ensured that when the first bevel gear rotates, one end of the first bevel gear can rotate normally in the rotating groove, and that when the two first connecting rods rotate, both ends of the two first connecting rods can rotate normally in several first gear grooves respectively. At the same time, it is ensured that when the third bevel gear rotates, one end of the third bevel gear can rotate normally in one of the first gear grooves.

[0024] In the above technical solution, the second connecting rod is located inside the glass door frame and is rotatably connected to the glass door frame. The two ends of the second connecting rod are rotatably connected to two second gear slots respectively. The rotating rod is rotatably connected to the glass door frame, and anti-slip textures are provided on the periphery of the rotating rod.

[0025] In this technical solution, it is ensured that when the second connecting rod rotates, it can rotate normally within the glass door frame, and that both ends of the second connecting rod can rotate normally within the two second gear slots respectively. At the same time, it is ensured that when the rotating rod rotates, it can rotate normally within the glass door frame. Furthermore, because the rotating rod has anti-slip textures on its periphery, when the user rotates the rotating rod by hand, the anti-slip textures will act on the rotating rod, reducing the problem of hand slippage.

[0026] The beneficial effects of this utility model are:

[0027] 1. This positionable sliding door and window, through the setting of limiting blocks, a first bevel gear, a second bevel gear, a first connecting rod, a third bevel gear, a fourth bevel gear, a second connecting rod, a fifth bevel gear, and a rotating rod, allows the user to drive several limiting blocks to rotate. Through the setting of mounting grooves, glass, slots, limiting plates, and limiting grooves, when several limiting blocks rotate to the appropriate position, several limiting blocks will release the fixing of the limiting plate, allowing the user to remove the limiting plate from the slot, facilitating the removal of the glass. The above structure design allows the user to simultaneously drive several buckles to rotate, enabling several buckles to quickly release the fixing of the limiting plate, allowing the user to quickly replace the glass, improving the speed of glass replacement and thus increasing the efficiency of glass replacement.

[0028] 2. This positionable sliding door and window, through the setting of threaded groove and threaded sleeve, allows the threaded sleeve to move towards the glass door frame under the action of the threaded groove, and tightly press against the glass door frame, fixing the rotating rod inside the glass door frame. The above structure design allows the user to fix the rotating rod inside the glass door frame, preventing the rotating rod from rotating due to external influences, which would affect the normal fixation of the limiting plate, and improving the stability of the overall device.

Once the fixation of the limit plate 6 is released, the user can replace the glass 4, ensuring that the user can quickly replace the glass 4 and improving the efficiency of glass 4 replacement.

[0051] Example 2:

[0052] This embodiment provides a positionable sliding door / window, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the driving component includes:

[0053] A plurality of first gear slots 12 are formed inside the glass door frame 2 and are respectively connected to a plurality of rotating slots 8. A first bevel gear 13 and a second bevel gear 14 are rotatably connected in each of the plurality of first gear slots 12, and the first bevel gear 13 and the second bevel gear 14 mesh with each other. One end of each of the plurality of first bevel gears 13 extends into the plurality of rotating slots 8 and is respectively fixedly connected to a plurality of limiting blocks 10.

[0054] Two connecting slots 15 are formed inside the glass door frame 2 and are respectively connected to several first gear slots 12. A first connecting rod 16 is rotatably connected in each of the two connecting slots 15, and the two ends of the two first connecting rods 16 extend into several first gear slots 12 and are respectively fixedly connected to several second bevel gears 14.

[0055] Two second gear slots 17 are formed inside the glass door frame 2, and the two second gear slots 17 are respectively connected to two of the first gear slots 12. A third bevel gear 18 and a fourth bevel gear 19 are rotatably connected in each of the two second gear slots 17, and the third bevel gear 18 and the fourth bevel gear 19 mesh with each other. One end of each of the two third bevel gears 18 extends into one of the two first gear slots 12 and is fixedly connected to one end of each of the two first connecting rods 16. A second connecting rod 20 is fixedly connected between the two fourth bevel gears 19.

[0056] The fifth bevel gear 21 is rotatably connected in one of the second gear slots 17 and meshes with one of the fourth bevel gears 19. A rotating rod 22 is fixedly connected to the fifth bevel gear 21, and one end of the rotating rod 22 passes through the inner wall of one of the second gear slots 17 and extends to the outside.

[0057] A fixing component is located on the rotating rod 22 and is used to fix the rotating rod 22.

[0058] In operation, the user manually rotates the lever 22, causing the fifth bevel gear 21 to rotate within one of the second gear slots 17. This causes the fifth bevel gear 21 to rotate within one of the second gear slots 17, and the fourth bevel gear 19 to rotate via the second connecting rod 20. When both fourth bevel gears 19 rotate, they respectively drive two third bevel gears 18 to rotate within the two second gear slots 17. The two third bevel gears 18 then drive two first connecting rods 16 to rotate within the two connecting slots 15. When the two first connecting rods 16 rotate, their ends drive several second bevel gears 14 to rotate within several first gear slots 12, which in turn drive several first bevel gears 13 to rotate. These first bevel gears 13 then drive several limit blocks 10 to rotate within several limit slots 7, ensuring that the user can simultaneously rotate several limit blocks 10.

[0059] Example 3:

[0060] This embodiment provides a positionable sliding door / window, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a fixing component:

[0061] The threaded groove 23 is opened on the periphery of the rotating rod 22. The threaded groove 23 is threadedly connected to the threaded sleeve 24, and the threaded sleeve 24 is located on one side of the glass door frame 2. The periphery of the threaded sleeve 24 is provided with anti-slip texture.

[0062] In use, the user rotates the threaded sleeve 24 by hand, causing the threaded sleeve 24 to move towards the glass door frame 2 under the action of the threaded groove 23. When the threaded sleeve 24 moves to the appropriate position, it will press tightly against the glass door frame 2, fixing the rotating rod 22 inside the glass door frame 2 and preventing it from rotating. This ensures that the rotating rod 22 will not be affected by external factors and improves the stability of the overall device.

[0063] Example 4:

[0064] This embodiment provides a positionable sliding door and window, which, in addition to the technical solution of the above embodiment, also has the following technical features: one end of the first bevel gear 13 is rotatably connected to the rotating groove 8, the two ends of the two first connecting rods 16 are respectively rotatably connected to a plurality of first gear grooves 12, and one end of the third bevel gear 18 is rotatably connected to one of the first gear grooves 12.

[0065] Specifically, it is ensured that when the first bevel gear 13 rotates, one end of the first bevel gear 13 can rotate normally in the rotating groove 8, and that when the two first connecting rods 16 rotate, both ends of the two first connecting rods 16 can rotate normally in several first gear grooves 12 respectively. At the same time, it is ensured that when the third bevel gear 18 rotates, one end of the third bevel gear 18 can rotate normally in one of the first gear grooves 12.

[0066] Example 5:

[0067] This embodiment provides a positionable sliding door and window. In addition to the technical solution of the above embodiment, it also has the following technical features: the second connecting rod 20 is located inside the glass door frame 2 and is rotatably connected to the glass door frame 2; the two ends of the second connecting rod 20 are rotatably connected to two second gear slots 17 respectively; the rotating rod 22 is rotatably connected to the glass door frame 2; and anti-slip texture is provided on the periphery of the rotating rod 22.

[0068] Specifically, it is ensured that when the second connecting rod 20 rotates, it can rotate normally within the glass door frame 2, and that both ends of the second connecting rod 20 can rotate normally within the two second gear slots 17 respectively. At the same time, it is ensured that when the rotating rod 22 rotates, it can rotate normally within the glass door frame 2. Furthermore, because the rotating rod 22 has anti-slip textures on its circumference, when the user rotates the rotating rod 22 by hand, the anti-slip textures on the circumference of the rotating rod 22 will help reduce the problem of hand slippage.

[0069] Working principle:

[0070] In use, the user manually rotates the rotating rod 22, causing the fifth bevel gear 21 to rotate within one of the second gear slots 17. This causes the fifth bevel gear 21 to rotate within one of the second gear slots 17, and the fourth bevel gear 19, via the second connecting rod 20, rotates the other fourth bevel gear 19. When both fourth bevel gears 19 rotate, they respectively drive two third bevel gears 18 to rotate within the two second gear slots 17. The two third bevel gears 18 then drive two first connecting rods 16 to rotate within the two connecting slots 15. When the two first connecting rods 16 rotate, their ends respectively drive several second bevel gears... Gear 14 rotates within several first gear slots 12, causing several second bevel gears 14 to drive several first bevel gears 13 to rotate, which in turn drive several limit blocks 10 to rotate within several limit slots 7. This ensures that the user can drive several limit blocks 10 to rotate simultaneously. When several limit blocks 10 rotate forward to a suitable position, they release the fixation on the limit plate 6. When several limit blocks 10 rotate in the reverse direction to a suitable position, they fix the limit plate 6 within the slot 5. Once the fixation on the limit plate 6 is released, the user can replace the glass 4, ensuring that the user can quickly replace the glass 4 and improving the efficiency of glass 4 replacement.

[0071] When in use, the user rotates the threaded sleeve 24 by hand, so that the threaded sleeve 24 is moved towards the glass door frame 2 by the action of the threaded groove 23. When the threaded sleeve 24 moves to the appropriate position, the threaded sleeve 24 will be tightly pressed against the glass door frame 2, fixing the rotating rod 22 inside the glass door frame 2 and preventing it from rotating. This ensures that the rotating rod 22 will not be affected by external factors and improves the stability of the overall device.

[0072] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
