Technical Field

[0001] This utility model relates to the field of door and window processing technology, specifically a seamless splicing and fastening device for door and window corners. Background Technology

[0002] Doors and windows are categorized as enclosure components or partition components based on their location, and each has different design requirements, including functions such as heat insulation, sound insulation, waterproofing, and fireproofing. New requirements emphasize energy conservation; in cold regions, heat loss through door and window gaps accounts for approximately 25% of total heating consumption. The airtightness of doors and windows is a crucial aspect of energy-saving design. During manufacturing, a fastening device is needed to secure the doors and windows before seamless splicing of the corners can be achieved.

[0003] Existing fastening devices typically involve workers assembling door and window posts, placing them on the fastening device for fixation, and then seamlessly processing the joints at the corners of the doors and windows. However, these fastening devices can only fix straight door and window posts, not curved ones. This means that when seamlessly splicing curved doors and windows, workers need to assist in fixing them, thus limiting the applicability of the fastening devices and making them unsuitable for processing requirements of seamless splicing of different door and window corners.

[0004] According to announcement number CN221135816U, an aluminum profile door and window processing splicing and fixing device is provided, including an operating table.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a seamless splicing and fastening device for door and window corners, including a support platform 1. One end of the support platform 1 is provided with an adjustment groove 2. Two sets of adjustment grooves 2 are provided. The inner cavity of the two sets of adjustment grooves 2 is provided with an adjustment component 3 for adjusting the fastening position of the door and window corner. The top of the adjustment component 3 is provided with a fixing frame 4. The top of the fixing frame 4 is provided with a fixing structure 5 for fixing the door and window corner. The other end of the support platform 1 is provided with a sliding groove 6. The sliding groove 6 is arc-shaped. The inner cavity of the sliding groove 6 is slidably connected to a sliding seat 7. The surface of the sliding seat 7 is provided with a positioning structure 8 for positioning the sliding position. The top of the sliding seat 7 is provided with a positioning clip 9 for clamping the door and window post. The upper surface of the support platform 1 is fixedly connected with a support seat 10 for supporting the door and window post.

[0024] The door and window pillars are placed on the adjusting component 3 and then fixed by the fixing structure 5. After fixing, the adjusting component 3 is rotated to move the positioned door and window pillars, thus adjusting their position. When splicing the corners of curved door and window pillars, the curved door and window pillars are placed on the positioning clamp 9. Then, according to the required width of the door and window pillars to be spliced, the sliding block 7 is pushed to move within the sliding groove 6. Finally, the positioning structure 8 positions the sliding block 7, allowing the door and window pillars to be spliced ​​with the curved door and window pillars. Then, workers perform seamless splicing of the door and window corners, thus fixing the curved door and window pillars and avoiding the need for workers to assist in fixing them, thereby expanding the application range of the fastening device. It can meet the processing needs of seamless splicing of different door and window corners.

[0025] The adjusting assembly 3 includes a screw 31 located inside the adjusting groove 2. The screw 31 is rotatably connected to the inner wall of the adjusting groove 2 via a rotating shaft. One end of the screw 31 passes through the adjusting groove 2 and is fixedly connected to a handle 32. A threaded sleeve 33 is threadedly connected to the outer surface of the screw 31. A movable seat 34 is provided on the outer surface of the threaded sleeve 33. The top end of the movable seat 34 is fixedly connected to the bottom end of the fixed frame 4. Rotating the handle 32 causes the screw 31 to rotate. The rotation of the screw 31 drives the threaded sleeve 33 to move through the threaded connection, causing the threaded sleeve 33 to move the movable seat 34. The movable seat 34 then moves the fixed frame 4, allowing the position of the door and window pillars to be adjusted after fixing, facilitating subsequent processing.

[0026] Both sides of the movable seat 34 are fixedly connected to sliders 11. The inner side wall of the adjustment groove 2 is provided with a slot. The sliders 11 are slidably connected to the inner cavity of the slot of the adjustment groove 2. The sliders 11 support both sides of the movable seat 34, preventing the movable seat 34 from flipping when the screw 31 rotates, thus improving the stability of the movable seat 34 when it moves in the inner cavity of the adjustment groove 2.

[0027] The positioning structure 8 includes a positioning hole 81, which is formed on the surface of the slide block 7. A positioning pin 82 is inserted and slidably connected to the inner cavity of the positioning hole 81. A fixing hole 83 is formed in the inner cavity of the slide groove 6. The inner cavity of the fixing hole 83 engages with the surface of the positioning pin 82. After the slide block 7 moves, the positioning pin 82 is inserted into the inner cavity of the positioning hole 81, and the bottom end of the positioning pin 82 moves to the inner cavity of the fixing hole 83 to fix the position of the slide block 7. Several sets of fixing holes 83 are provided, and the sets of fixing holes 83 are evenly distributed in the inner cavity of the slide groove 6. The setting of fixing holes 83 increases the adjustment range of the slide block 7.

[0028] The fixed structure 5 includes a movable sleeve 51, which is inserted and fixed to the top of the fixed frame 4. A movable rod 52 is inserted and slidably connected to the inner cavity of the movable sleeve 51. A fixed plate 53 is fixedly connected to the bottom end of the movable rod 52. When the movable rod 52 moves inside the movable sleeve 51 and fixes the door frame post, the fixed plate 53 presses and fixes the door frame post by its own weight as it descends.

[0029] A spring 12 is fitted on the outer surface of the movable rod 52. The spring 12 is located between the fixed plate 53 and the fixed frame 4. The spring 12 supports the fixed frame 4 at one end and the fixed plate 53 at the other end, so that the spring 12 continuously pushes the fixed plate 53 to move and squeeze the door frame post.

[0030] A support rod 13 is fixedly connected to the top of the fixed plate 53. A through hole is opened on the surface of the fixed frame 4. The support rod 13 is inserted into and slides in the inner cavity of the through hole of the fixed frame 4. The support rod 13 supports both ends of the fixed plate 53, thereby improving the stability of the fixed plate 53 when it moves up and down in the fixed frame 4.

[0031] In practical use: Pulling the movable rod 52 moves the fixed plate 53 upward, compressing the spring 12. Then, the door and window pillars are placed on the movable seat 34. Releasing the movable rod 52 causes the spring 12 to release and rebound, pushing the fixed plate 53 downward to fit against the door and window pillars, compressing them. Then, rotating the handle 32 rotates the screw 31, causing the screw 31 to rotate and drive the threaded sleeve 33 to move through the threaded connection. This causes the threaded sleeve 33 to move the movable seat 34, thus adjusting the position of the fixed door and window pillars. After adjustment, the two sets of door and window pillars are combined and spliced. The staff then performs seamless splicing processing on the door and window pillars at the corners. For curved door and window pillars... During the fixing process, the door and window post is placed on the support base 10 for support. Then, the slide block 7 is moved according to the width of the door and window post. After adjusting the position of the slide block 7 within the slide groove 6, the positioning pin 82 is inserted into the inner cavity of the positioning hole 81. The bottom end of the positioning pin 82 extends into the inner cavity of the fixing hole 83 to fix the position of the slide block 7. Then, the curved door and window post is placed on the positioning clip 9 for fixing. One end of the curved door and window post contacts the door and window post on the support base 10. The operator then performs seamless splicing processing of the door and window corners, thereby achieving the fixing of the curved door and window post. This eliminates the need for auxiliary fixing work by the operator and expands the application range of the fastening device. It can meet the processing needs of seamless splicing of different door and window corners.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
