Description

Technical Field

[0001] This utility model relates to the field of aluminum profile assembly technology, specifically a right-angle connecting frame for assembling and splicing aluminum profiles. Background Art

[0002] Currently, aluminum profiles are widely used in many fields, including machinery manufacturing, transportation machinery, power machinery, and the aerospace industry. Aluminum profiles play an important role in these fields. For example, in the aerospace field, aluminum alloy profiles are widely used in aircraft manufacturing and maintenance due to their lightweight and high strength characteristics, which can significantly reduce aircraft weight and improve fuel efficiency. In addition, aluminum profiles are also used in building structures and manufacturing installation, door and window frame decoration, etc., with advantages such as good wind pressure resistance and non-combustibility.

[0003] Most aluminum profiles are produced as single supports, which are not easy to use. Therefore, multiple aluminum profile frames need to be spliced ​​together into different shapes using connectors to be applied to various scenarios.

[0004] Conventional aluminum profile connectors on the market are assembled using bolts and multiple connectors, which requires carrying many parts and can lead to part loss due to compression. Therefore, a new technical solution needs to be designed to solve this problem, which can quickly assemble two sets of aluminum profiles using a single connector. Utility Model Content

[0005] The purpose of this utility model is to provide a right-angle connecting frame for assembling and splicing aluminum profiles, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a right-angle connecting frame for assembling and splicing aluminum profiles, comprising a connecting frame, an aluminum rod on one side of the connecting frame, slots being provided at the center of the four corners of the aluminum rod, a limiting groove being provided inside each set of slots, a connecting frame being inserted into the slot on one side, and driving grooves being provided inside both sides of the connecting frame, with a quick-installation positioning mechanism installed inside both sets of driving grooves;

[0007] The quick-installation positioning mechanism includes an extrusion block movably installed in the drive groove, piston holes opened at both ends of the side wall of the extrusion block, a piston rod movably installed in each set of piston holes, a wedge block fixedly installed on the inner side of the piston rod, and an anti-slip block fixedly installed at the other end of each set of piston rods. The cross-section of each set of wedge blocks is trapezoidal.

[0008] As an optional solution to the technical solution of this application, the anti-blocking block corresponds to the limiting groove, the two sides of the extrusion block correspond to the two adjacent sets of wedge blocks, and the two adjacent sets of piston holes correspond to the driving groove.

[0009] As an optional solution to the technical solution of this application, the connecting frame is L-shaped, and the cross-sectional area of ​​the limiting groove is larger than the cross-sectional area of ​​the slot, so that the anti-slip block installed on the side wall of the connecting frame is supported in the limiting groove.

[0010] As an optional solution to the technical solution of this application, each set of piston rods has a spring sleeved on its outer wall, and each set of springs is fixedly installed on both sides of the wedge block and the side wall of the drive groove, which can make the piston rod automatically reset.

[0011] As an optional solution to the technical solution of this application, screw holes are provided in the middle of both sides of the connecting frame, and screw rods are threaded into both sets of screw holes. The other ends of the two sets of screw rods are rotatably connected to the middle of the two sets of extrusion blocks, which can push the extrusion blocks to move.

[0012] As an optional solution to the technical solution of this application, both ends of one side of the two sets of drive grooves are connected to limit holes, and each set of limit holes is movably installed with a limit rod. The two sets of limit rods are respectively fixedly installed with the side wall of the corresponding extrusion block, which can limit the extrusion block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The technical solution of this application involves installing the connecting frame on both sides of two sets of aluminum rods. Then, the two sets of screws on the connecting frame can be screwed on separately. After the screws continuously press the extrusion block inside the drive groove, the extrusion block will continuously move closer to the two sets of wedge blocks. When the extrusion block presses the two sets of wedge blocks on both sides, it can push the two sets of piston rods to move along the piston groove direction, ensuring that the anti-slip blocks on the outside of the two sets of piston rods are tightly attached to the limiting groove on the inside of the aluminum rods, so that the two sets of loose aluminum rods are firmly fixed by the connecting frame. This device is quick to install and easy to carry.

[0015] 2. The technical solution of this application has two sets of drive slots with limit holes connected at both ends on one side, and each set of limit holes has a limit rod installed in it. When the operator tightens the two sets of screws on the connecting frame and continuously squeezes the extrusion block inside the drive slot, the limit rod in the limit hole can support and limit the extrusion block in the drive slot, ensuring that the extrusion block moves along the direction of the limit hole, while squeezing the wedge blocks on both sides.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a right-angle connecting frame for assembling and splicing aluminum profiles, including a connecting frame 2, an aluminum rod 1 on one side of the connecting frame 2, slots 11 are opened in the middle of the four corners of the aluminum rod 1, a limiting groove 12 is opened in the inner side of each set of slots 11, the connecting frame 2 is inserted into the slot 11 on one side, and a driving groove 21 is opened in the inner side of both sides of the connecting frame 2, and a quick-installation positioning mechanism is installed in the two sets of driving grooves 21.

[0022] The quick-installation positioning mechanism includes a pressing block 22 movably installed in the drive groove 21, piston holes 23 opened at both ends of the side wall of the pressing block 22, piston rods 24 movably installed in each set of piston holes 23, wedge blocks 25 fixedly installed on the inner side of the piston rods 24, and anti-sliding blocks fixedly installed at the other end of each set of piston rods 24. The cross-section of each set of wedge blocks 25 is trapezoidal. The anti-sliding blocks correspond to the limiting grooves 12. The two sides of the pressing block 22 correspond to the two adjacent sets of wedge blocks 25. The two adjacent sets of piston holes 23 correspond to the drive groove 21. The connecting frame 2 is L-shaped. The cross-sectional area of ​​the limiting groove 12 is larger than the cross-sectional area of ​​the slot 11, so that the anti-sliding blocks installed on the side wall of the connecting frame 2 are supported in the limiting groove 12.

[0023] In this technical solution, after the connecting frame 2 is installed on both sides of the two sets of aluminum rods 1, the two sets of screws 32 on the connecting frame 2 can be screwed on respectively. After the screws 32 continuously squeeze the extrusion block 22 inside the drive groove 21, the extrusion block 22 will continuously move closer to the two sets of wedge blocks 25. When the extrusion block 22 squeezes the two sets of wedge blocks 25 on both sides, it can push the two sets of piston rods 24 to move along the piston groove direction, ensuring that the anti-slip blocks on the outside of the two sets of piston rods 24 are tightly attached to the limiting groove 12 on the inside of the aluminum rod 1, so that the two sets of loose aluminum rods 1 are firmly fixed by the connecting frame 2. This device is quick to install and easy to carry.

[0024] In some technical solutions, limit holes 33 are opened at both ends of one side of the two sets of drive grooves 21. Limit rods 34 are movably installed in each set of limit holes 33. The two sets of limit rods 34 are fixedly installed on the side wall of the corresponding extrusion block 22, which can limit the extrusion block 22.

[0025] In this technical solution, when the operator tightens the two sets of screws 32 on the connecting frame 2 and continuously squeezes the extrusion block 22 inside the drive groove 21, the extrusion block 22 inside the drive groove 21 can be supported and limited by the limiting rod 34 in the limiting hole 33, so as to ensure that the extrusion block 22 moves along the direction of the limiting hole 33 and squeezes the wedge blocks 25 located on both sides.

[0026] In some technical solutions, screw holes 31 are provided in the middle of both sides of the connecting frame 2, and screw rods 32 are threadedly installed in both sets of screw holes 31. The other ends of the two sets of screw rods 32 are rotatably connected to the middle of the two sets of extrusion blocks 22, which can push the extrusion blocks 22 to move.

[0027] In this technical solution, the two sets of screws 32 on the connecting frame 2 are screwed together. After the screws 32 continuously squeeze the extrusion block 22 inside the drive groove 21, the extrusion block 22 will continuously move closer to the two sets of wedge blocks 25 and squeeze the two sets of wedge blocks 25.

[0028] In some technical solutions, each set of piston rods 24 is fitted with a spring 3 on its outer wall, and each set of springs 3 is fixedly installed on both sides of the wedge block 25 and the side wall of the drive groove 21, which can make the piston rod 24 automatically reset.

[0029] In this technical solution, when the operator needs to disassemble the connecting frame 2, the operator only needs to rotate the screw 32 in the opposite direction to separate the pressing block 22 from the two sets of wedge blocks 25. The two sets of wedge blocks 25 will automatically return to the drive groove 21 under the support force of the spring 3.

[0030] When using a right-angle connecting frame assembled from aluminum profiles, it should be noted that this utility model is a right-angle connecting frame assembled from aluminum profiles. All components are general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0031] In use, first, after the two sets of aluminum rods 1 are joined at right angles, the two ends of the connecting frame 2 can be inserted into the slots 11 on the two sets of aluminum rods 1 respectively, so that the two sets of aluminum rods 1 can be quickly spliced ​​into a right angle shape through the connecting frame 2. At the same time, after the two sides of the connecting frame 2 are respectively installed on one side of the two sets of aluminum rods 1, the two sets of screws 32 on the connecting frame 2 can be tightened respectively. After the screws 32 continuously squeeze the extrusion block 22 inside the drive groove 21, the extrusion block 22 will continuously move closer to the two sets of wedge blocks 25. When the two sides of the extrusion block 22 squeeze the two sets of wedge blocks 25 respectively, the two sets of piston rods 24 can be pushed to move along the piston groove direction, ensuring the outer side of the two sets of piston rods 24 is protected. The slider fits tightly into the limiting groove 12 inside the aluminum rod 1, so that the two loose aluminum rods 1 are firmly fixed by the connecting frame 2. This device is quick to install and easy to carry. At the same time, the two sets of drive grooves 21 are connected to the two ends of one side and have limiting holes 33. Each limiting hole 33 has a limiting rod 34 installed in it. When the operator tightens the two sets of screws 32 on the connecting frame 2 and continuously squeezes the extrusion block 22 inside the drive groove 21, the limiting rod 34 in the limiting hole 33 can support and limit the extrusion block 22 in the drive groove 21, ensuring that the extrusion block 22 moves along the direction of the limiting hole 33, while squeezing the wedge blocks 25 located on both sides.
