Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, specifically to an aluminum profile for portable doors and windows. Background Technology

[0002] With the acceleration of global urbanization and the continuous development of the real estate and decoration markets, the market demand for doors and windows, as core components of building envelopes, is expanding year by year. Statistics show that China adds over 1 billion square meters of new building doors and windows annually, and the market size for old building renovation is also growing at an average annual rate of 8%. There is an urgent need for efficient and convenient door and window products. Aluminum alloys, due to their lightweight, corrosion resistance, ease of processing, and recyclability, have achieved a penetration rate of over 60% in the door and window industry, becoming the mainstream material.

[0003] There are many existing technologies for aluminum profiles used in doors and windows, such as:

[0004] According to Chinese patent application number CN201720148074.9, specifically, it describes an aluminum profile for portable aluminum doors and windows. The portable aluminum profile includes a horizontal frame plate and a vertical frame plate, which are fitted together. The horizontal frame plate includes a 45-degree angled groove on both sides, and the vertical frame plate includes 45-degree angled hooks on both sides. The 45-degree angled groove and the 45-degree angled hook are fitted together. This utility model's portable aluminum profile for doors and windows, with its 45-degree angled groove and hook, allows for convenient and quick connection and fixation of the horizontal and vertical frame plates, improving door and window installation efficiency.

[0005] Traditionally, the connection between vertical and horizontal frame panels is mainly achieved through screw connections, welding, and corner bracket splicing. Screw connections require positioning, drilling, and screwing in each hole, which is time-consuming and labor-intensive, and requires specialized tools. Welding connections require adjusting the verticality of the profiles before welding, and grinding and touch-up painting are required after welding, making the process cumbersome. When splicing corner brackets, the adjustment range of the bolts on the movable corner brackets is limited, and they are prone to loosening due to wear after long-term use, reducing the convenience and efficiency of splicing aluminum profiles. Utility Model Content

[0007] To achieve the above objectives, this utility model provides an aluminum profile for portable doors and windows, comprising an aluminum profile body, the aluminum profile body including a vertical frame plate and a horizontal frame plate, wherein the upper and lower ends of the vertical frame plate are engaged with a connecting component, wherein: the connecting component includes a connecting seat, the bottom of the connecting seat is respectively fixedly connected to a first snap-fit ​​plate and a second snap-fit ​​plate, both the first snap-fit ​​plate and the second snap-fit ​​plate are provided with a slot, the bottom of the connecting seat is provided with a plurality of snap-fit ​​blocks arranged in a ring, and a rotating rod is rotatably connected inside the connecting seat, the rotation of the rotating rod drives the plurality of snap-fit ​​blocks to move horizontally synchronously and engage with the slots.

[0008] The beneficial effects of this utility model are:

[0009] 1. By engaging the first snap-fit ​​plate with the first through hole in the connecting assembly, and by engaging the second snap-fit ​​plate with the groove in the connecting assembly, the connecting assembly can be quickly installed while the connection position of the vertical frame plate and the horizontal frame plate can be accurately positioned, thereby improving the installation accuracy between the vertical frame plate and the horizontal frame plate.

[0010] 2. By rotating the rotating rod, multiple locking blocks are driven to move simultaneously and engage with multiple slots, achieving screwless and quick connection and locking between the vertical and horizontal frame plates. No drilling or tools are required; the connection can be completed by manual rotation, effectively ensuring the stability of the connection while improving installation efficiency.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

The horizontal frame plate has first through holes symmetrically arranged at both ends inside, and the first snap-fit ​​plate is snapped into the first through holes.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by making a preliminary connection in this way, a three-dimensional limiting structure is formed, the connection position of the vertical frame plate and the horizontal frame plate is accurately located, and the installation accuracy between the vertical frame plate and the horizontal frame plate is improved.

[0014] Preferably, the lower end of the outer side of the rotating rod is provided with a bidirectional thread, and a movable cylinder is symmetrically threaded to the outer side of the bidirectional thread. Several ear plates are fixedly connected to the outer sides of the two movable cylinders in an annular shape.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 As shown, this embodiment provides an aluminum profile for portable doors and windows, including an aluminum profile body 1. The aluminum profile body 1 includes a vertical frame plate 11 and a horizontal frame plate 12. Considering that the splicing process of aluminum profiles in traditional technology is cumbersome, time-consuming and labor-intensive, and the splicing convenience and efficiency are low, a connecting component 2 is snapped together at the upper and lower ends of the vertical frame plate 11. The connecting component 2 includes a connecting seat 21. A first snap-fit ​​plate 22 and a second snap-fit ​​plate 23 are fixedly connected to the bottom of the connecting seat 21. The first snap-fit ​​plate 22 and the second snap-fit ​​plate 23 are both provided with slots 24. Several snap-fit ​​blocks 26 are arranged in a ring at the bottom of the connecting seat 21. A rotating rod 25 is rotatably connected inside the connecting seat 21. By rotating the rotating rod 25, the multiple snap-fit ​​blocks 26 are driven to move horizontally synchronously and snap together inside the slots 24. No drilling or tools are required. The connection can be completed by manually rotating the rotating rod 25, which improves the installation efficiency.

[0030] In summary, the improvement of this embodiment lies in:

[0031] By synchronously moving and engaging with the slots 24 through multiple locking blocks 26, a screwless and quick connection and locking of the vertical frame plate 11 and the horizontal frame plate 12 can be achieved. No drilling or tools are required, making the operation convenient and improving the installation efficiency. Furthermore, the ring array of locking blocks 26 and slots 24 with multiple locking points ensures that the force is evenly distributed, reduces local stress concentration, and extends the service life of the profile.

[0032] Based on the above, other structures also need to be disclosed in detail, such as:

[0033] The vertical frame plate 11 and the horizontal frame plate 12 have several annular grooves 13 inside. Second snap-fit ​​plates 23 engage with the grooves 13. The horizontal frame plate 12 has symmetrically arranged first through holes 14 at both ends, and first snap-fit ​​plates 22 engage with the first through holes 14. During the initial connection of the vertical frame plate 11 and the horizontal frame plate 12, one end of the horizontal frame plate 12 is first brought into contact with the side of one end of the vertical frame plate 11, maintaining the parallelism of the height of the vertical frame plate 11 and the horizontal frame plate 12. Then, the connecting component 2 is snapped onto the top of the vertical frame plate 11. During this process, the first snap-fit ​​plates 22 are inserted into the first through holes 14 inside the horizontal frame plate 12, and multiple second snap-fit ​​plates 23 are inserted into multiple grooves 13 in the vertical frame plate 11. This initial connection forms a three-dimensional limiting structure, precisely positioning the connection position between the vertical frame plate 11 and the horizontal frame plate 12, thus improving the installation accuracy between the two.

[0034] The lower end of the outer side of the rotating rod 25 is provided with a bidirectional thread 27. The outer side of the bidirectional thread 27 is symmetrically connected to a movable cylinder 28. Several ear plates 210 are fixedly connected to the outer side of the two movable cylinders 28 in an annular shape. The ear plates 210 are symmetrically fixedly connected to the side of the locking block 26 near the movable cylinder 28. A connecting rod 29 is rotatably connected between the ear plates 210 on the outer side of the movable cylinder 28 and the ear plates 210 on the side of the locking block 26. Several second through holes 15 are designed in an annular shape at the upper and lower ends of the interior of the vertical frame plate 11. When it is necessary to lock the connection between the vertical frame plate 11 and the horizontal frame plate 12, the internal thread of the moving cylinder 28 engages with the external thread of the bidirectional thread 27 by rotating the rotating rod 25, thereby driving the two moving cylinders 28 to move relative to each other. The locking block 26 is connected to the moving cylinder 28 through the connecting rod 29 and the ear plate 210, thereby pushing multiple locking blocks 26 to move horizontally synchronously. Multiple locking blocks 26 pass through the second through hole 15 and engage with the slot 24, realizing the screwless quick connection and locking of the vertical frame plate 11 and the horizontal frame plate 12. No drilling or tools are required, and the connection can be completed by manual rotation, which improves the installation efficiency. When disassembling, the rotating rod 25 is rotated in the opposite direction, and the two moving cylinders 28 move in opposite directions, driving the locking block 26 to move towards the rotating rod 25, canceling the engagement between the locking block 26 and the slot 24, which allows for quick disassembly, facilitates maintenance or reuse, and reduces after-sales costs.

[0035] An installation groove 211 is provided at the upper edge of the inner side of the rotating rod 25. A limiting component 3 is installed inside the installation groove 211, including a limiting rod 31. The limiting rod 31 is engaged with the inside of the connecting seat 21. A spring 32 is fixedly connected between one side of the limiting rod 31 and one side of the installation groove 211. Before rotating the rotating rod 25, the limiting rod 31 is pulled upwards to disengage it from the connecting seat 21. After the rotating rod 25 has rotated, the pulling force on the limiting rod 31 is released. The force generated by the spring 32 pulls the limiting rod 31 back to its original position, causing the limiting rod 31 to re-engage with the connecting seat 21, thus mechanically locking the rotating rod 25 and preventing it from loosening due to vibration or long-term use, ensuring the long-term stability of the connection structure.

[0036] In summary, the working principle of this solution is as follows:

[0037] First, one end of the horizontal frame plate 12 is brought into contact with the side of one end of the vertical frame plate 11, keeping the vertical frame plate 11 and the horizontal frame plate 12 parallel in height. Then, the connecting component 2 is snapped into the top of the vertical frame plate 11. During this process, the first snap-fit ​​plate 22 is inserted into the first through hole 14 inside the horizontal frame plate 12, and multiple second snap-fit ​​plates 23 are inserted into multiple grooves 13 in the vertical frame plate 11. This initial connection forms a three-dimensional limiting structure, accurately positioning the connection position between the vertical frame plate 11 and the horizontal frame plate 12, improving the installation accuracy between the vertical frame plate 11 and the horizontal frame plate 12. Then, the limiting rod 31 is pulled upward to cancel the connection between the limiting rod 31 and the connecting seat 21. Next, the rotating rod 25 is rotated, and the internal thread of the moving cylinder 28 meshes with the external thread of the bidirectional thread 27, thereby driving the two moving cylinders 28 to move relative to each other. The locking block 26 is connected to the moving cylinder 28 through the connecting rod 29 and the ear plate 210, thereby pushing multiple locking blocks 26 to move horizontally in sync. As the frame moves, multiple locking blocks 26 pass through the second through hole 15 and engage with the slot 24, achieving a screwless, quick connection and locking between the vertical frame plate 11 and the horizontal frame plate 12. No drilling or tools are required; connection can be completed by manual rotation, improving installation efficiency. The ring-array multi-point engagement of the locking blocks 26 and slot 24 evenly distributes force, reduces local stress concentration, and extends the service life of the profile. During disassembly, rotating the rotating rod 25 in the opposite direction causes the two moving cylinders 28 to move in opposite directions, moving the locking blocks 26 towards the rotating rod 25, thus canceling the engagement between the locking blocks 26 and slot 24, allowing for quick disassembly. This facilitates maintenance or reuse, reducing after-sales costs. After the rotating rod 25 has rotated, the pull on the limiting rod 31 is released, and the force generated by the spring 32 pulls the limiting rod 31 back to its original position, causing the limiting rod 31 to re-engage with the connecting seat 21, forming a mechanical lock on the rotating rod 25. This prevents the rotating rod 25 from loosening due to vibration or long-term use, ensuring the long-term stability of the connection structure.
