Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile technology, and specifically relates to an aluminum profile assembly with a connection structure. Background Technology

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. They are widely used in transportation, equipment and machinery manufacturing, and durable consumer goods industries. They can also be used to make door and window frames.

[0003] In existing aluminum profiles, most are fixed by argon arc welding to achieve the purpose of connection. However, argon arc welding is a complicated process that requires a lot of equipment. Moreover, the welded joints need to be broken during disassembly and assembly, which makes it impossible to reuse the aluminum profiles and causes waste. Therefore, we provide an aluminum profile assembly with a connection structure. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum profile assembly with a connection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum profile assembly with a connection structure, comprising a first aluminum profile and a second aluminum profile, wherein a plug block is fixedly connected to one end of the second aluminum profile, the plug block has a set of positioning holes, the plug block is inserted into the inner cavity at the bottom of the first aluminum profile, a pin is inserted into the positioning holes, a connecting plate is fixedly connected to one end of the pin and located outside the first aluminum profile, an L-shaped hollow plate is fixedly connected to the bottom inside the first aluminum profile, the other end of the connecting plate is inserted into the inner cavity of the L-shaped hollow plate, and the connecting plate and the L-shaped hollow plate are fixedly connected by bolts.

[0006] Using the above method, the plug-in block at one end of aluminum profile No. 2 is inserted into the inner cavity at the bottom of aluminum profile No. 1, so that aluminum profile No. 1 and aluminum profile No. 2 form a preliminary connection. Next, the pin on the connecting plate is inserted into the positioning hole from the bottom of the front surface of aluminum profile No. 1, so that one end of the connecting plate is inserted into the inner cavity of the L-shaped hollow plate. The pin is used to limit the position of the plug-in block for a second time. Then, the bolt is turned into the L-shaped hollow plate from the top with an external tool until one end of the bolt protrudes from the bottom of the L-shaped hollow plate and the movement stops. The connecting plate is fixed by the bolt to achieve the purpose of rapid installation.

[0007] In a preferred embodiment of an aluminum profile assembly with a connecting structure, one end of the first aluminum profile is provided with a rectangular through hole for the plug-in block to move laterally, and the size of the rectangular through hole is larger than the size of the plug-in block.

[0008] By adopting the above solution, since the size of the rectangular through hole is larger than the size of the plug-in block, the friction between the plug-in block and the No. 1 aluminum profile is reduced during the connection process, so that the plug-in block can be smoothly inserted into the inner cavity of the No. 1 aluminum profile, thereby improving the connection efficiency.

[0009] In a preferred embodiment of an aluminum profile assembly with a connecting structure, both the L-shaped hollow plate and the connecting plate are provided with threaded holes for bolts to move up and down, and the number of threaded holes is three.

[0010] By adopting the above solution, since the inner wall of the threaded hole is provided with internal threads, the compatibility between the internal threads and the external threads on the bolt surface is utilized to prevent the bolt from getting stuck during rotation.

[0011] In a preferred embodiment of an aluminum profile assembly with a connecting structure, the number of positioning holes is seven, and the distance between two positioning holes is three centimeters.

[0012] Using the above solution, since the distance between the two positioning holes is three centimeters, when it is necessary to adjust the distance between aluminum profile No. 1 and aluminum profile No. 2, precise adjustment can be achieved without the need for external measuring tools.

[0013] In a preferred embodiment of an aluminum profile assembly with a connecting structure, a circular through hole is provided at the bottom of the front surface of the first aluminum profile for the pin to pass through, and the size of the circular through hole is adapted to the pin.

[0014] By adopting the above solution, the position of the pin is located through the circular through hole, making it convenient for the user to operate.

[0015] In a preferred embodiment of an aluminum profile assembly with a connecting structure, both the first and second aluminum profiles are L-shaped and have the same dimensions.

[0016] By adopting the above solution, since aluminum profile No. 1 and aluminum profile No. 2 have the same size, the aesthetics of the connection between aluminum profile No. 1 and aluminum profile No. 2 are improved after installation.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the plug-in block at one end of the No. 2 aluminum profile is inserted into the inner cavity at the bottom of the No. 1 aluminum profile, so that the No. 1 aluminum profile and the No. 2 aluminum profile form a preliminary connection. Then, the pin on the connecting plate is inserted into the positioning hole from the bottom of the front surface of the No. 1 aluminum profile, so that one end of the connecting plate is inserted into the inner cavity of the L-shaped hollow plate. The pin is used to limit the position of the plug-in block for a second time. Then, the bolt is turned into the L-shaped hollow plate from the top with an external tool until one end of the bolt protrudes from the bottom of the L-shaped hollow plate and the movement stops. The connecting plate is fixed by the bolt to achieve the purpose of quick installation.

[0019] 2. Because the distance between the two positioning holes is three centimeters, this utility model can achieve precise adjustment without the need for external measuring tools when it is necessary to adjust the distance between aluminum profile No. 1 and aluminum profile No. 2.

[0024] See also Figure 1-3An aluminum profile assembly with a connecting structure includes a first aluminum profile 1 and a second aluminum profile 2. One end of the first aluminum profile 1 has a rectangular through hole for a connecting block 3 to move laterally. The size of the rectangular through hole is larger than the size of the connecting block 3. Because the through hole is larger than the connecting block 3, friction between the connecting block 3 and the first aluminum profile 1 is reduced during the connection process, allowing the connecting block 3 to be smoothly inserted into the inner cavity of the first aluminum profile 1, thus improving the connection efficiency. One end of the second aluminum profile 2 is fixedly connected to the connecting block 3. The plug-in block 3 has a set of positioning holes 4. The plug-in block 3 is inserted into the inner cavity of the bottom of the first aluminum profile 1. A pin 6 is inserted into the positioning hole 4. One end of the pin 6, located outside the first aluminum profile 1, is fixedly connected to a connecting plate 5. An L-shaped hollow plate 7 is fixedly connected to the bottom inside the first aluminum profile 1. The other end of the connecting plate 5 is inserted into the inner cavity of the L-shaped hollow plate 7. The connecting plate 5 and the L-shaped hollow plate 7 are fixedly connected by bolts 8. Both the L-shaped hollow plate 7 and the connecting plate 5 have threaded holes for the bolts 8 to move up and down. Furthermore, there are three threaded holes. Because the inner wall of the threaded holes has internal threads, the compatibility of the internal threads with the external threads on the bolt 8 surface prevents the bolt 8 from jamming during rotation. The insertion block 3 at one end of the second aluminum profile 2 is inserted into the inner cavity at the bottom of the first aluminum profile 1, thus forming a preliminary connection between the first and second aluminum profiles. Next, the pin 6 on the connecting plate 5 is inserted from the bottom of the front surface of the first aluminum profile 1 into the positioning hole 4, while simultaneously inserting one end of the connecting plate 5 into the inner cavity of the L-shaped hollow plate 7. The pin 6 provides a secondary positioning for the plug block 3. Then, using an external tool, the bolt 8 is turned from the top of the L-shaped hollow plate 7 until one end of the bolt 8 protrudes from the bottom of the L-shaped hollow plate 7 and the movement stops. The connecting plate 5 is fixed by the bolt 8 to achieve the purpose of quick installation. A circular through hole is provided at the bottom of the front surface of the first aluminum profile 1 for the pin 6 to pass through. The circular through hole is adapted to the size of the pin 6. The use position of the pin 6 is positioned by the circular through hole, which is convenient for the user to operate.

[0025] See Figure 3 As shown, there are seven positioning holes 4, and the distance between two positioning holes 4 is three centimeters. Because the distance between two positioning holes 4 is three centimeters, when it is necessary to adjust the distance between aluminum profile 1 and aluminum profile 2, precise adjustment can be achieved without the need for external measuring tools. Figure 1 As shown, both aluminum profile 1 and aluminum profile 2 are L-shaped and have the same size. Because aluminum profile 1 and aluminum profile 2 have the same size, the aesthetics of the connection between aluminum profile 1 and aluminum profile 2 are improved after installation.

[0026] In use, first insert the plug block 3 at one end of aluminum profile 2 into the inner cavity at the bottom of aluminum profile 1, so that aluminum profile 1 and aluminum profile 2 form a preliminary connection. Next, insert the pin 6 on the connecting plate 5 into the positioning hole 4 from the bottom of the front surface of aluminum profile 1, so that one end of the connecting plate 5 is inserted into the inner cavity of the L-shaped hollow plate 7. The pin 6 is used to limit the position of the plug block 3 for a second time, which improves its stability during use. Then, use an external tool to turn the bolt 8 from the top of the L-shaped hollow plate 7 until one end of the bolt 8 protrudes from the bottom of the L-shaped hollow plate 7 and the movement stops. The connecting plate 5 is fixed by the bolt 8. Similarly, when it is necessary to remove, the operation is reversed, so as to achieve the purpose of quick installation. Since the distance between the two positioning holes 4 is three centimeters, when it is necessary to adjust the distance between aluminum profile 1 and aluminum profile 2, it is possible to achieve precise adjustment without the need for external measuring tools.
