Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, specifically to a connection structure for aluminum profile components. Background Technology

[0002] Aluminum profiles, as a common metal material, are widely used in construction, industry, aerospace and other fields due to their comprehensive performance advantages. Their advantages are specifically manifested in the balance between lightweight and high strength, excellent corrosion resistance, good processability and formability, recyclability and environmental friendliness. Moreover, in the existing technology, the connection structure design of aluminum profiles can meet the engineering needs of different fields.

[0003] Currently, L-shaped aluminum alloy connectors are generally used to connect and install aluminum profiles. However, relying solely on L-shaped aluminum alloy connectors results in poor structural strength at the connection point, making it prone to damage under stress during use. To overcome these shortcomings, existing technology (Chinese patent application number 202323188113.2, application date 2023-11-25) provides an aluminum profile connection structure. Through the use of a connecting block and two extension brackets, the installation of two aluminum profiles can be positioned and limited, facilitating the connection between the two profiles. The rapid assembly of aluminum profiles involves placing an L-shaped reinforcing plate at the inner angle of the two assembled aluminum profiles and installing fixing bolts to secure the connecting block and the L-shaped reinforcing plate. This improves the structural strength of the connected aluminum profiles and facilitates their use. However, the above structure requires multiple steps, such as positioning and assembly, adding reinforcing plates, and tightening bolts, when connecting a large number of aluminum profiles. These multiple steps are time-consuming and labor-intensive, and the labor intensity for workers is also high, resulting in low efficiency in connecting and installing aluminum profiles.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a connection structure for aluminum profile components that can effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for aluminum profile components, so as to solve the problem that the above-mentioned structure in the background art requires multiple operations such as positioning and assembly, adding reinforcing plates and tightening bolts when connecting aluminum profiles. When connecting a large number of aluminum profiles, the multiple operations are time-consuming and labor-intensive, and the labor intensity of workers is also high, resulting in low efficiency of aluminum profile connection and installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for aluminum profile components, comprising an aluminum profile body, wherein a through hole is provided at the center of the aluminum profile body, and multiple aluminum profile bodies can be extended or vertically connected by connectors; an automatic snap-fit ​​assembly is provided between the aluminum profile body and the connectors, the automatic snap-fit ​​assembly including snap-fit ​​interfaces on four sides of the ends of the aluminum profile body, and upright plates are fixedly connected to both sides of the outer wall of the aluminum profile body on each snap-fit ​​interface, and magnetic sheets are embedded and installed on the adjacent end faces of each upright plate; the automatic snap-fit ​​assembly further includes a connecting base block located at the center of the connector body, and the connecting base block has a cubic structure, wherein the six sides of the connecting base block... The outer wall of the profile is fixedly connected with a plug rod and four snap-fit ​​pieces, and the snap-fit ​​pieces are evenly distributed on the outer side of the plug rod with the plug rod as the center. One of the plug rods is inserted into the inner end of the through hole, and the four snap-fit ​​pieces on the outer side of the plug rod are correspondingly inserted between the snap-fit ​​interface and the inner side of the upright plate. Each snap-fit ​​piece has a rotating groove, and the inner side of the rotating groove is limited by a self-locking rotating shaft to limit the rotation of a limiting rod. The limiting rod is composed of a central aluminum rod and iron blocks at both ends. The limiting rod, which is snapped into the inner side of the aluminum profile body, is rotated perpendicular to the snap-fit ​​piece by the magnetic attraction of the iron blocks and magnetic pieces at both ends, that is, snapped into one end of the upright plate. An automatic reinforcement component is also provided between the aluminum profile body and the connector to assist the automatic snap-fit ​​component in further stabilizing the connection.

[0007] Preferably, the central part of the aluminum profile body has a hollow structure due to the opening of the central through hole, and the four corners are formed with arrow-shaped protrusions.

[0008] Preferably, the self-locking rotating shaft is symmetrically formed on both sides of the limiting rod, and the frictional force at the rotating connection between it and the rotating groove is relatively large.

[0009] Preferably, the limiting rod is in a position that is completely overlapped with the rotating groove under the initial self-locking action of the self-locking shaft.

[0010] Preferably, the automatic reinforcement component includes threaded rods fixedly connected to the inner sides of both ends of the through hole by a reinforcing frame. The inner side of the connecting base block and each plug rod is provided with an installation groove, and the inner side of the installation groove is limited to rotate by a threaded sleeve. The threaded rod and the threaded sleeve are threadedly connected.

[0011] Preferably, the reinforcing frame consists of a central rod and several circular plates fixed to its outer side, and the outer wall of the circular plates is fixedly connected to the inner wall of the central through hole.

[0012] Preferably, the ends of the threaded sleeve that are close to each other are formed into spherical blocks, and a receiving groove that connects to the mounting groove is provided at the center of the connecting base block, and the spherical blocks rotate inside the mounting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This connection structure for aluminum profile components, by setting up an aluminum profile body, connectors, and an automatic snap-fit ​​assembly between them, only requires aligning the plug rod and snap-fit ​​piece of the connecting base block with the through hole and snap-fit ​​interface of the aluminum profile body and inserting them in, thus realizing the connection and installation of multiple aluminum profile bodies. Furthermore, the automatic reinforcement assembly assists the automatic snap-fit ​​assembly in ensuring a stable connection. The entire process only requires the plugging step, which is time-saving and labor-saving, and reduces the labor intensity of workers, thereby achieving… The efficiency of aluminum profile connection and installation has been greatly improved. The specific contents are as follows: (1) By setting up the aluminum profile body, connectors and automatic snap-fit ​​components between them, you only need to insert one side of the connecting base block into one end of the aluminum profile body, and then use the magnetic attraction of the magnetic sheet and the limiting rod to limit the position. The limiting rod can be snapped into one end of the upright plate, thus realizing the stable connection between the connector and the aluminum profile body. The whole process only requires the insertion step, which is more time-saving and labor-saving, and reduces the labor intensity of workers, thereby greatly improving the efficiency of aluminum profile connection and installation.

[0014] By setting up an automatic reinforcement component, when the plug-in rod is aligned with the through hole for insertion, the threaded rod will simultaneously enter the inner side of the threaded sleeve until a tight threaded connection is achieved. This self-locking thread effectively prevents the plug-in rod from coming out of the through hole, thereby improving the connection stability between the aluminum profile body and the connector.

[0015] The self-locking effect can be achieved by the large friction between the self-locking shaft and the rotating groove. In the initial state, the limiting rod and the rotating groove are in a completely overlapping position. This allows the locking piece to be easily inserted between the two upright plates when the locking piece is connected to the locking interface, thereby realizing the locking function between the limiting rod and the upright plate.

[0016] By using the combination of the ball block and the mounting groove, the contact area between the end of the threaded sleeve and the connecting base block can be minimized, thereby reducing the friction force experienced by the threaded sleeve during rotation, so as to facilitate the threaded connection between the threaded rod and the threaded sleeve.

Detailed Implementation

[0024] 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.

[0025] Example 1: Please refer to Figures 1-5 The present invention provides the following technical solution: a connection structure for aluminum profile components, including an aluminum profile body 1, a through hole 2 is provided in the center of the aluminum profile body 1, the middle part of the aluminum profile body 1 is hollow due to the opening of the through hole 2, and arrow-shaped protrusions are formed at the four corners. The above structure can achieve overall lightweighting without affecting the connection strength of the aluminum profile body 1, thereby saving material costs.

[0026] Multiple aluminum profile bodies 1 can be extended or vertically connected by connectors 7. An automatic snap-fit ​​assembly is provided between the aluminum profile body 1 and the connectors 7. The automatic snap-fit ​​assembly includes snap-fit ​​interfaces 3 opened on the four sides of the ends of the aluminum profile body 1. The outer wall of the aluminum profile body 1 is fixedly connected to two sides of each snap-fit ​​interface 3, and each upright plate 4 is fitted with a magnetic sheet 14 on the adjacent end face.

[0027] Furthermore, the automatic snap-fit ​​assembly also includes a connecting base block 8 located at the center of the connector 7. The connecting base block 8 has a cubic structure, and each of the six outer walls of the connecting base block 8 is fixedly connected with a plug rod 9 and four snap-fit ​​pieces 10. The snap-fit ​​pieces 10 are evenly distributed on the outer side of the plug rod 9 with the plug rod 9 as the center. One plug rod 9 is inserted into the interior of one end of the through hole 2, and the four snap-fit ​​pieces 10 on the outer side of the plug rod 9 are correspondingly inserted between the snap-fit ​​interface 3 and the inner side of the upright plate 4. Each snap-fit ​​piece 10 has a rotating groove 11, and the inner side of the rotating groove 11 is limited by a self-locking rotating shaft 12 to rotate a limiting rod 13. The self-locking rotating shaft 12 is symmetrically formed on both sides of the limiting rod 13, and it is related to the rotating... The rotating connection of the groove 11 has a large friction to achieve a certain self-locking effect. The limiting rod 13 is composed of a central aluminum rod and iron blocks at both ends. The limiting rod 13, which is inserted into the inner side of the aluminum profile body 1, is rotated to be perpendicular to the snap-fit ​​piece 10 by the magnetic attraction of the iron blocks at both ends and the magnetic piece 14, that is, snap-fitted to one end of the upright plate 4. Under the initial self-locking action of the self-locking rotating shaft 12, the limiting rod 13 is in a position that is completely overlapped with the rotating groove 11. This allows the snap-fit ​​piece 10 to be easily inserted between the two upright plates 4 when the snap-fit ​​piece 10 is connected to the snap-fit ​​interface 3. Then, under the magnetic attraction of the limiting rod 13 and the magnetic piece 14, the snap-fit ​​action of the limiting rod 13 and the upright plate 4 is achieved.

[0028] By setting up an automatic snap-fit ​​assembly between the aluminum profile body 1, the connector 7, and the connector, when connecting the aluminum profile bodies 1, simply align the plug rod 9 and snap-fit ​​piece 10 on one side of the connecting base block 8 with the central through hole 2 and snap-fit ​​interface 3 at one end of the aluminum profile body 1 and insert them into the corresponding positions. This allows the snap-fit ​​piece 10 to snap into the space between the two upright plates 4. At this time, the magnetic piece 14 embedded on the upright plate 4 will attract the limiting rod 13 to rotate and adhere to it through magnetic attraction. In this way, the limiting rod 13 can be snapped into one end of the upright plate 4, preventing the snap-fit ​​piece 10 from coming out of the snap-fit ​​interface 3. This achieves a stable connection between the connector 7 and the aluminum profile body 1. By repeating the above operation, other aluminum profile bodies 1 can be installed on other surfaces of this connector 7, thus realizing the connection and installation of multiple aluminum profile bodies 1. The entire process only requires this one plug-in operation, which is time-saving and labor-saving, and reduces the labor intensity of workers, thereby greatly improving the efficiency of aluminum profile connection and installation.

[0029] Example 2: Based on Example 1, please refer to... Figure 2 , Figure 4 , Figures 5-6An automatic reinforcement component is also provided between the aluminum profile body 1 and the connector 7 to assist the automatic snap-fit ​​component in further stabilizing the connection. The automatic reinforcement component includes threaded rods 6 fixedly connected to the inner sides of both ends of the through hole 2 via a reinforcing frame 5. The reinforcing frame 5 consists of a central rod body and several circular plates fixed to its outer side. The outer wall of the circular plates is fixedly connected to the inner wall of the through hole 2 to ensure the connection strength of the threaded rods 6 inside the through hole 2 with minimal material consumption. The connecting base block 8 and the inner side of each plug-in rod 9 are provided with mounting grooves 15. The inner side of the mounting groove 15 is limited by a threaded sleeve 17, and the threaded rod 6 is threadedly connected to the threaded sleeve 17. By setting an automatic reinforcement component, when the plug rod 9 is aligned with the through hole 2 for insertion, the threaded rod 6 will simultaneously enter the inner side of the threaded sleeve 17. At this time, under the action of the thread, the threaded sleeve 17 will rotate inside the mounting groove 15 until the threaded rod 6 and the threaded sleeve 17 are tightly threadedly connected. In this way, the self-locking function of the thread can effectively prevent the plug rod 9 from coming out of the through hole 2, thereby improving the connection stability between the aluminum profile body 1 and the connector 7.

[0030] Furthermore, the adjacent ends of the threaded sleeve 17 are all formed into ball blocks 18. A receiving groove 16 that connects with the mounting groove 15 is provided at the center of the connecting base block 8, and the ball blocks 18 rotate inside the mounting groove 15. Through the cooperation between the ball blocks 18 and the mounting groove 15, the contact area between the end of the threaded sleeve 17 and the connecting base block 8 can be minimized to the greatest extent, thereby reducing the friction force experienced by the threaded sleeve 17 when it rotates, so as to facilitate the threaded connection between the threaded rod 6 and the threaded sleeve 17.
