Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and in particular to a quick-assembly aluminum profile. Background Technology

[0002] Aluminum profiles, as a lightweight, high-strength, corrosion-resistant, and easy-to-process structural material, are widely used in various fields such as construction, industrial equipment, mechanical frames, exhibition booth construction, and furniture manufacturing. As modern manufacturing demands increasing modularity, standardization, and assembly efficiency, the connection methods of aluminum profiles are gradually evolving from traditional welding and bolt fixing to faster, more convenient, and detachable methods.

[0003] Currently, common aluminum profile splicing methods mainly include using corner brackets, connecting plates, embedded nuts, and fasteners for fixing. Some products also use a plug-in connection method with slots and plugs to achieve detachable connection. However, these connection methods still have certain limitations: First, most traditional connection methods require the use of fastening components such as screws and nuts, as well as special tools for installation, which is cumbersome and has low assembly efficiency. Second, although the existing quick-connect structure improves the convenience of assembly, the number of connection points is limited, the overall stability is poor, and it is easy to loosen or even detach when subjected to vibration, impact, or large loads.

[0004] Therefore, there is an urgent need to provide an aluminum profile that can be quickly assembled and has a stable connection. Utility Model Content

[0005] In order to overcome the shortcomings of existing aluminum profile connection methods, such as low assembly efficiency, inconvenient disassembly and assembly, and insufficient connection stability, this utility model provides an aluminum profile that can be quickly spliced ​​and has a stable connection.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a rapidly assembled aluminum profile comprising two aluminum profile bodies, a first fixing sleeve, a second fixing sleeve, a fixing structure, a retaining ball, and an elastic element. Each aluminum profile body has multiple sliding grooves on its surface. The ends of the two aluminum profile bodies are respectively engaged with the first fixing sleeve and the second fixing sleeve. The first fixing sleeve has a slot structure, and the second fixing sleeve has an insertion block structure adapted to the slot structure. Both the first and second fixing sleeves are equipped with fixing structures. The insertion block structure of the second fixing sleeve has circular holes on both sides, and a retaining ball is slidably installed inside the circular holes. The retaining ball is connected to the inner wall of the circular hole via an elastic element. The inner wall of the slot structure of the first fixing sleeve has a retaining hole matching the retaining ball.

[0007] As a preferred embodiment of this utility model, the elastic element is a compression spring, with one end connected to the ball and the other end connected to the inner wall of the circular hole.

[0008] As a preferred embodiment of this utility model, the slot structure of the first fixing sleeve and the bottom of the insertion block structure of the second fixing sleeve both adopt a rounded chamfer design.

[0009] As a preferred technical solution of this utility model, the fixing structure includes a fastening bolt and a locking block. The first fixing sleeve and the second fixing sleeve are respectively provided with through holes on both sides. The fastening bolt is rotatably arranged inside the through hole. The locking block is slidably arranged inside the groove corresponding to the position of the fastening bolt. The locking block is threadedly connected to the fastening bolt.

[0010] As a preferred embodiment of this invention, the shape of the card block matches the shape of the sliding groove.

[0011] As a preferred technical solution of this utility model, it further includes a mounting base, a threaded sleeve, a threaded rod, a boss, and a limiting ball. The mounting base is fixedly connected to the side of the first fixed sleeve, and the threaded sleeve is fixedly connected to the side of the second fixed sleeve. The lower end of the threaded sleeve can be inserted into the corresponding hole of the mounting base. The threaded sleeve is threadedly provided with a threaded rod inside, and a boss is provided at the lower end of the threaded rod. Limiting balls are movably installed on both sides of the threaded sleeve.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a first fixing sleeve and a second fixing sleeve at the end of the aluminum profile and adopting a structure design that combines a slot and a plug, the two aluminum profiles can be quickly connected and assembled without complicated tools, which greatly improves the assembly efficiency. In addition, the first fixing sleeve and the second fixing sleeve are respectively provided with a locking hole and a locking ball and an elastic element structure. When the plug is inserted into the slot, the locking ball automatically springs into the locking hole to form a self-locking structure, which effectively prevents the connection part from loosening or separating due to external force, and improves the stability and load-bearing capacity of the overall connection.

[0013] 2. The fixing structure adopts a combination of fastening bolts and clips. By rotating the fastening bolts, the fixing sleeve can be tightened or loosened, so that the fixing sleeve can be firmly installed or quickly disassembled, which is convenient for later maintenance and replacement.

[0014] 3. Through the linkage between the threaded rod, threaded sleeve, boss and limit ball, the connection stability of the first fixed sleeve and the second fixed sleeve is further enhanced, and the safety and stability of the overall structure are improved. Attached Figure Description

[0024] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0025] Example 1: Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6A quick-assembly aluminum profile includes two aluminum profile bodies 1, a first fixing sleeve 3, a second fixing sleeve 4, a fixing structure, a retaining ball 8, and an elastic element 10. Each aluminum profile body 1 has four sliding grooves 2 on its surface. The ends of the two aluminum profile bodies 1 are respectively engaged with the first fixing sleeve 3 and the second fixing sleeve 4. The first fixing sleeve 3 has a slot structure, and the second fixing sleeve 4 has an insertion block structure adapted to the slot structure. Furthermore, the interior of the slot structure of the first fixing sleeve 3 and the bottom of the insertion block structure of the second fixing sleeve 4 are designed with rounded chamfers to facilitate guidance during insertion. In alignment, both the first fixing sleeve 3 and the second fixing sleeve 4 are provided with fixing structures for fixing them to the aluminum profile body 1. The front and rear sides of the insertion block structure of the second fixing sleeve 4 are provided with round holes 7. A retaining ball 8 is slidably installed inside the round hole 7. The retaining ball 8 is connected to the inner wall of the round hole 7 by an elastic element 10. The elastic element 10 is a compression spring, one end of which is connected to the retaining ball 8 and the other end is connected to the inner wall of the round hole 7, ensuring that the retaining ball 8 always has the tendency to pop outward when not subjected to external force. The slot structure of the first fixing sleeve 3 has retaining holes 9 on the front and rear side walls that match the retaining ball 8.

[0026] When assembling aluminum profiles, the first fixing sleeve 3 and the second fixing sleeve 4 are first installed on the ends of the two aluminum profile bodies 1 to be spliced, and the two are fixed by the fixing structure. Then, the insert structure of the second fixing sleeve 4 is inserted into the slot structure of the first fixing sleeve 3 to achieve a preliminary connection. During this process, the locking ball 8 is squeezed and compresses the elastic element 10 into the round hole 7. When the insert is fully inserted, the locking ball 8 pops out under the reset action of the elastic element 10 and locks into the corresponding locking hole 9, thereby achieving a lock between the two fixing sleeves and ensuring a stable and reliable connection.

[0027] Example 2: Based on Example 1, please refer to... Figure 2 and Figure 3 The fixing structure includes a fastening bolt 5 and a locking block 6. The front and rear sides of the first fixing sleeve 3 and the second fixing sleeve 4 are respectively provided with through holes. The fastening bolt 5 is rotatably installed inside the through hole. The locking block 6 is slidably installed inside the slide groove 2 corresponding to the position of the fastening bolt 5. The locking block 6 is threadedly connected to the fastening bolt 5. Furthermore, the shape of the locking block 6 matches the slide groove 2 to ensure that it slides stably in the slide groove 2 without deviation.

[0028] During the installation of the first fixing sleeve 3 or the second fixing sleeve 4, the locking block 6 is first slid into the groove 2 of the aluminum profile body 1 as a positioning point. Then, the fixing sleeve is inserted into the end of the aluminum profile body 1, and the locking block 6 is aligned with the corresponding structure on the fixing sleeve. Next, the fastening bolt 5 is screwed into the through hole of the fixing sleeve and threadedly connected to the locking block 6. By rotating the fastening bolt 5, the fixing sleeve is fixed on the locking block 6 and the locking block 6 is pressed into the groove 2, thereby achieving a firm installation of the fixing sleeve. When disassembly is required, the fastening bolt 5 is rotated in the opposite direction to loosen the fixing sleeve, and it can be easily removed from the aluminum profile body 1.

[0029] Please see Figure 7 and Figure 8 It also includes a mounting base 11, a threaded sleeve 12, a threaded rod 13, a boss 14, and a limiting ball 15. The mounting base 11 is fixedly connected to the front side of the first fixing sleeve 3, and the threaded sleeve 12 is fixedly connected to the front side of the second fixing sleeve 4. The lower end of the threaded sleeve 12 can be inserted into the corresponding hole of the mounting base 11. The threaded sleeve 12 is threaded with a threaded rod 13 inside. The lower end of the threaded rod 13 is provided with a boss 14. The limiting ball 15 is movably installed on the front and rear sides of the threaded sleeve 12.

[0030] When the insert structure of the second fixed sleeve 4 is inserted into the slot structure of the first fixed sleeve 3, the threaded sleeve 12 is simultaneously inserted into the mounting base 11. At this time, the threaded rod 13 is manually rotated to move downward along the thread direction of the threaded sleeve 12, causing the boss 14 to move downward together. When the boss 14 contacts and presses the limiting ball 15, it will restrict the limiting ball 15 from retracting inward, thereby firmly locking the threaded sleeve 12 onto the mounting base 11 and preventing it from falling off due to vibration or external force. This further enhances the connection stability of the first fixed sleeve 3 and the second fixed sleeve 4. When disassembly is required, the threaded rod 13 is rotated in the opposite direction to move upward and release the pressure of the boss 14 on the limiting ball 15. At this time, the limiting ball 15 can freely retract into the threaded sleeve 12 under the action of external force, releasing the limiting function. Thus, the threaded sleeve 12 can be pulled out from the mounting base 11, completing the overall separation operation.

[0031] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
