DETAILED DESCRIPTION OF THE INVENTION

[0025] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0026] Embodiment: As shown in the figure, a connecting component for aluminum profile furniture according to the present invention includes a square aluminum column 1. The square aluminum column 1 is composed of a connecting body 1-1 at the center and four support bodies 1-2 fixedly connected to the four sides of the connecting body 1-1. The outer contour of the connecting body 1-1 is square, and a through hole 1-11 is provided at the center. The support body 1-2 is a square pipe fitting, and is equidistantly installed on the connecting body 1-1 with the connecting body 1-1 as the center. Two oppositely arranged limiting strips 1-21 are respectively fixedly connected to the opposite surfaces of two adjacent support bodies 1-2. Square slot holes 1-22 are provided at both ends of the support body 1-2 with the connecting body 1-1 as the center. Each side of the direction slot hole is parallel to the support body 1-2 respectively. A small rectangular space is cut off from each of the four corners of the four support bodies 1-2 that are close to each other. After cutting, the two ends of the four support bodies 1-2 are cut inward, while the connecting body 1-1 remains unchanged, leaving a square space that can be clamped between the connecting body 1-1 and the four support bodies 1-2. V-shaped grooves penetrating through are also provided in the middle of the four sides of the connecting body 1-1, and the limiting strips 1-21 are symmetrically distributed on both sides of the V-shaped groove. A storage space is formed between the limiting strip 1-21 and the V-shaped groove, which is convenient for installing the light strip by sliding it inward from both ends. At the same time, a lampshade can also be installed at the gap between the light strip and the limiting strip 1-21 for decoration. After the square aluminum column 1 is snap-connected to the connecting component 2, the limiting strip 1-21 above the light strip limits the light strip in the storage space, and it can only swing up and down. When the gap is relatively large, the light strip can also be clamped by the fixing member 10 to make it completely positioned. After assembly, through the installation holes provided on the fixing member 10, a cabinet door or other components can also be installed at any position on the square aluminum. Both ends of the square aluminum column 1 are detachably connected with a connection component 2. The connection component 2 includes a square connection head 3, a connecting rod 4, a connecting shaft 5, a connecting plate 6, a wiring board 7, a contact circuit board 8 and a cover plate 9. One end of the connecting rod 4 is threadedly connected to the middle of the surface of the square connection head 3, and the other end is inserted into the connection main body 1-1, so that the connection component 2 is tightly connected to the square aluminum column 1. The connecting shaft 5 is diagonally installed on the square connection head 3 and the other end is inserted into the support body 1-2, so that the connection component 2 is limited and fixed to the square aluminum column 1. The connecting plate 6 is in a square frame structure and is clamped in the square slot 1-22. Three pairs of positive and negative solder joints 6-1 and a pair of positive and negative contacts 6-2 are arranged along the inner hole edge on the surface of the connecting plate 6. The back surface of the contact circuit board 8 is installed on the square connection head 3, and a group of positive connection points 8-1 and a group of negative connection points 8-2 are arranged on the front surface. Through the positive and negative contacts 6-2, they are respectively in contact with the negative connection point 8-2 and the positive connection point 8-1, conducting the connecting plate 6 and the contact circuit board 8. The wiring board 7 is installed in the square connection head 3 and is electrically connected to the contact circuit board 8 through a wire. A power interface is welded on the wiring board 7, and the wiring board 7, the contact circuit board 8 and the connecting plate 6 are powered by an external power supply. The cover plate 9 is snap-connected to the surface of the square connection head 3. When in use, the cover plate 9 can have a central opening or be completely closed. It is convenient for the power interface to be connected and conducted with the square connection head 3 through the opening. When it is not necessary to connect the power interface and the blank space connecting the square aluminum column 1, the completely closed cover plate 9 is used to seal it to prevent insects or water from entering. The connecting plate 6 is in the same shape as the square slot 1-22, that is, the outer contour is square, and a square hole consistent with the connection main body 1-1 is opened inside. When installing, the connecting plate 6 can be clamped and fixed in the square slot 1-22, and the three pairs of positive and negative solder joints 6-1 are exactly located on the three storage spaces. The other pair of positive and negative contacts 6-2 are elastic copper columns located in the fourth storage space and are in contact and conduction with the contact circuit board 8.

[0027] The square connector 3 is a hollow cube with one side communicating with the outside, and square notches 3-1 are provided on the remaining five sides. The square notches 3-1 are opened centered on the center of the square. An installation groove 3-2 with a square outside and a round inside is also provided at the center of the square notch 3-1. A threaded hole 3-3 for screwing connection with the connecting rod 4 is opened at the center of the square. A wire passing hole 3-4 is also opened at one corner of the installation groove 3-2. A set of insertion holes 3-5 for inserting the connecting shaft 5 are opened at the diagonals of the square notch 3-1. Two chutes 3-6 perpendicular to the through surface are also provided inside the square connector 3. A wiring board 7 is slidably connected in the chutes 3-6. A set of connection holes 3-7 located in the middle are symmetrically provided on the square notch 3-1. A set of convex buttons 9-1 are provided on the back of the cover plate 9. The cover plate 9 is detachably connected to the square connector 3 by connecting the convex buttons 9-1 with the connection holes 3-7. The square notches 3-1 on the five sides can all be buckled by the convex buttons 9-1 on the back of the cover plate 9 and the connection holes 3-7 to close the square notches 3-1 and make them flush with the outside of the square connector 3, which is convenient for placing against the wall. The installation groove 3-2 is used to place the contact circuit board 8 and the connection plate 6. Both components are structures with a square outside and a round inside. This structural form is convenient for adjusting the orientation and connection position during installation, enabling the light strips at any position to conduct with the positive and negative poles on the connection plate 6 to provide a power interface. The wiring board 7 is connected inside the square connector 3 through the chutes 3-6. Multiple sets of positive and negative wiring points are provided on the wiring board 7. A power interface is installed on the wiring board 7. The positive and negative pins of the power interface are welded and conducted with multiple sets of positive and negative wirings. Then, the positive and negative poles are respectively welded and conducted with the positive connection point 8-1 and the negative connection point 8-2 of the contact circuit board 8 through wires passing through the wire passing hole 3-4, enabling the power interface to provide driving power for the contact circuit board 8, thereby driving the light strip welded to the connection plate 6 to work for lighting.

[0028] Reference Figure 4, one of the positive and negative contacts 6-2 is located in the middle of the four sides of the connecting plate 6, and the other is located at the diagonal corners of the four sides of the connecting plate 6; there are four positive connection points 8-1 and four negative connection points 8-2, which are arranged in a circle on the contact circuit board 8. One group is located at the four corners of the contact circuit board 8, and the other group is located in the middle of the four sides of the contact circuit board 8. The outer contour of the contact circuit board 8 is square, and a round hole is opened in the center. Each positive connection point 8-1 on the contact circuit board 8 is connected, and a wiring hole is opened on the positive connection point 8-1. Each negative connection point 8-2 on the contact circuit board 8 is connected, and a wiring hole is opened on the negative connection point 8-2. The wire is connected to the contact circuit board 8 and the wiring board 7 through the wiring hole; the connecting plate 6 is the same size as the contact circuit board 8, and the positions of the positive and negative contacts 6-2 on the connecting plate 6 correspond to the positions of the positive connection point 8-1 and the negative connection point 8-2 on the contact circuit board 8 respectively. Specifically, taking the middle of the connecting plate 6 as the positive pole and the diagonal corner as the negative pole as an example, the middle of the corresponding contact circuit board 8 is the negative pole, and the four corners are the positive poles. When the connecting plate 6 rotates and adjusts the installation position by 90 degrees in the square slot 1-22, the positive contact of the connecting plate 6 always corresponds to the middle negative position on the contact circuit board 8 after rotation, and at the same time, the negative contact of the connecting plate 6 always corresponds to the positive position at the four corners of the contact circuit board 8 after rotation. That is, no matter how the connecting plate 6 adjusts its position in the square slot 1-22, it can ensure that the contact circuit board 8 can conduct the connecting plate 6 and provide a driving power supply for the connecting plate 6. Reference Figure 8 , the connecting rod 4 includes a threaded head 4-1, a shaft rod 4-2, a deep groove 4-3 and a rotating head 4-4. The shaft rod 4-2 is a smooth shaft, one end is connected to the threaded head 4-1, and the other end is connected to the rotating head 4-4. A slotted screwdriver slot is also provided on the end face of the rotating head 4-4. A deep groove 4-3 is arranged radially near the rotating head 4-4 of the shaft rod 4-2, and a rubber washer is installed in the deep groove 4-3. During use, the connecting rod 4 is connected to the through hole 1-11 on the connecting body 1-1, and the static friction force is provided by the rubber washer located in the deep groove 4-3 to prevent the square aluminum column 1 from shaking or falling off from the connecting rod 4, ensuring the connection stability. At the same time, the connecting rod 4 can be pulled out under external force for convenient disassembly and installation. During installation, the threaded head 4-1 is threadedly connected to the square connecting head 3, and a slotted screwdriver is used to drive the rotating head 4-4 to spin, so as to tightly connect the threaded head 4-1 to the square connecting head 3. Then, the contact circuit board 8, the connecting plate 6 and the square aluminum column 1 are sleeved in sequence, and the connecting shaft 5 at the diagonal corners of the square connecting head 3 is clamped with the hollow part at the diagonal corner of the support body 1-2 to prevent the square aluminum column 1 from spinning axially, and the fastening installation of the square aluminum column 1 and the square connecting head 3 is completed.

[0029] A fixing member 10 is also provided on the support body 1-2 and is slidably connected along the limiting strip 1-21. The fixing member 10 includes a slider 10-1 and a fastening screw 10-2. Corresponding sliding grooves 3-6 are provided on both sides of the slider 10-1 for the limiting strip 1-21, and a through hole 1-11 penetrating the bottom is provided at the upper end. The fastening screw 10-2 is rotatably connected in the through hole 1-11, and the outer surface of the slider 10-1 is flush with the outer surface of the support body 1-2. Through holes 1-11 are also provided on the surface of the fixing member 10 for installing a rotating bearing or a cabinet door support, and furniture components or lighting components can be freely installed on the square aluminum column 1.

[0030] Working principle and usage steps: The power driving member in the connecting component 2 is arranged at the through surface of the square connecting head 3, that is, the DC power interface is welded through the wiring board 7 and installed in the sliding groove 3-6, so that the power interface is entirely located within the square connecting head 3, while the interface is located on the surface of the through surface, and the wiring board 7 is prevented from falling out by buckling with the cover plate 9. An external drive is connected to the power interface to provide driving power to the square connecting head 3. Contact circuit boards 8 and connecting plates 6 are installed at the other five sides of the square connecting head 3. The positive and negative poles at the wiring board 7 are connected to the positive and negative poles on the contact circuit board 8 through wires, and then contact and connection are made through the positive and negative contacts 6-2 on the wiring board 7 and the contact circuit board 8, so that the three pairs of positive and negative pole solder joints 6-1 on the wiring board 7 are in a powered state. When the wiring board 7 is connected to the square aluminum column 1, the three pairs of positive and negative pole solder joints 6-1 are exactly located in the grooves on the four sides of the square aluminum column 1, that is, below the limiting strip 1-21. When a light strip is installed at the limiting strip 1-21, only the positive and negative poles of the light strip need to be connected to the positive and negative pole solder joints 6-1 at the wiring point to achieve lighting. One wiring board 7 can supply power to at most three light strips located on one square aluminum column 1 at a time. Five sides are provided on one square connecting head 3, that is, five wiring boards 7, and hidden power supply can be provided for the square aluminum columns 1 connected to each surface, without the need for additional layout, with a beautiful appearance and convenient assembly.

[0031] The present invention can be spliced and fixed with square aluminum columns in different directions through the connecting component. The square aluminum columns are fixed and limited at the connecting component by using a connecting shaft and a connecting rod, without the need for drilling and installation by screws, and the disassembly and installation are convenient. It can also be freely spliced into the desired furniture style according to the layout of the room. Through the fixing member, a cabinet door or a cabinet board can be installed to assemble the desired furniture layout. A light strip can also be arranged inside the square aluminum column. The external power is conducted to the interfaces of the direction connecting head and the square aluminum column through the connecting plate, the contact circuit board, and the wiring board. When installing the light strip, only the positive and negative poles of the light strip need to be welded at the corresponding positions on the connecting plate to drive the light strip to illuminate. The light strip is hidden inside the square aluminum column, and the connecting line passes through the connecting component, without exposing the cable and the connector, which is not only beautiful but also solves the wiring problem.

[0032] On the connecting plate of the present invention, three pairs of positive and negative electrode soldering points are provided, which can supply power to three surfaces of the square aluminum column, enabling the light strip to be installed for lighting on any surface of the square aluminum column. Even three light strips can be installed simultaneously to surround the square aluminum column. By splicing square aluminum columns and connecting components in different directions, a display cabinet or storage cabinet with auxiliary lighting can be assembled. With the cooperation of an external control circuit, intelligent lighting or display can be achieved.

[0033] In the present invention, the square aluminum column and the connecting component are fixedly connected only through the connecting rod and the connecting shaft, without the need for additional drilling and positioning. Therefore, the square aluminum column can be freely stepped on and broken for splicing and assembly, which is not only convenient for transportation and movement but also can freely change the style and layout after forming. Moreover, the surface of the aluminum profile frame is smoother, waterproof and corrosion-resistant, which is convenient for daily cleaning and wiping to improve the comfort of the home.

[0034] The above is only used to illustrate the technical solution of the present invention and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, shall be covered by the scope of the claims of the present invention.
