The utility model is convenient for adjusting the size according to actual conditions, so that the aluminum profile is more flexible, and the assembly plates in the aluminum profile are easy to replace, which improves the practicality of the entire aluminum profile. Although this patent solves some problems, there is still a problem that the connection structure needs to be positioned and fixed by screws, the installation time is long, and the installation efficiency is low. Therefore, it is very necessary to design an aluminum profile for frame assembly that is easy to assemble and connect quickly. Summary of the invention

[0004] The object of the present invention is to provide an aluminum profile for frame assembly to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an aluminum profile used for frame assembly, comprising an aluminum main frame, the aluminum main frame is provided with a secondary connecting rod, the side of the secondary connecting rod is provided with a plug-in connecting plate, the side of the aluminum main frame is provided with a connecting cross bar, the outer side of the aluminum main frame is provided with a rod-through connecting groove, the upper surface of the aluminum main frame is provided with a positioning slot, the inner side of the positioning slot is provided with a positioning protrusion, the end side of the aluminum main frame is provided with a through slot on both sides, the middle position of the two end sides of the aluminum main frame is provided with a central inner slot, the side edge of the aluminum main frame is fixedly connected with a convex edge strip, the rod-through connecting groove penetrates from one side of the aluminum main frame to the other side, the positioning protrusion is fixedly connected to the aluminum main frame, and the through slot penetrates from one end of the aluminum main frame to the other end. Through the above structure, when a platform needs to be built, the two aluminum main frames can be connected end to end so that the two aluminum main frames are connected at right angles, and the plug-in connecting plate is inserted into the aluminum The side connecting plate slot of the main frame is connected, and the connecting plate slot is passed through the through slot on the side of the end of another aluminum main frame to play an auxiliary installation role. When the two vertical aluminum main frames are connected, the secondary connecting rod can be inserted into the end of the horizontal aluminum main frame, so that the positioning slot at the end of the horizontal aluminum main frame is matched with the side strip of the secondary connecting rod, and the positioning convex block is matched with the inner groove of the strip, which can be quickly assembled by splicing connection. When it is necessary to build the top side inclined surface, the secondary connecting rod line can be spliced ​​on the top side of the vertical aluminum main frame, and the convex edge strip on the side of the other aluminum main frame is matched with the inner groove of the top side strip of the secondary connecting rod at this place, and then the end of the other secondary connecting rod is connected to the side of the horizontal secondary connecting rod here, and the through slot on the side of the horizontal secondary connecting rod here is spliced ​​with the connecting piece block. When the structure needs to be processed, the connecting cross bar can be inserted into the corresponding through rod connecting slot of the aluminum main frame, and installation screw buckles can be installed at both ends of the connecting cross bar for reinforcement. The frame can be built by splicing to improve the construction efficiency.

[0006] According to the above technical solution, a protective reinforcement device is provided on the inner side of the aluminum main frame, and the protective reinforcement device includes a reinforcement slider, a moisture-absorbing cotton block, a sealing sheet, a telescopic spring, and a fixed stopper. The reinforcement slider is slidably connected to the inside of the aluminum main frame, the moisture-absorbing cotton block is adhesively connected to the inner wall of the aluminum main frame, the sealing sheet is fixedly connected to the inner wall of the aluminum main frame, the telescopic spring is fixedly connected to the side of the reinforcement slider, and the fixed stopper is fixedly connected to the inside of the aluminum main frame. The side of the sealing sheet and the side of the reinforcement slider fit each other, the reinforcement slider is located on the inner side of the central inner groove, and the fixed stopper is fixedly connected to the telescopic spring. Through the above structure, when the aluminum main frame is used in a horizontal structure, a protective reinforcement device needs to be provided inside the aluminum main frame. Since the constructed bracket is often used indoors In outdoor scenes, water is easily accumulated inside the horizontal aluminum main frame, and the temperature difference between morning and evening outdoors will cause dew to condense on the outside of the aluminum main frame and enter the interior through the central inner grooves on both sides. Reinforced sliders and fixed blocks are set to block moisture from carrying dust or insects in the internal space, which will affect the normal insertion of the internal connection structure of the central inner groove. At the same time, when the weather is hot, the aluminum main frame will produce thermal expansion and contraction, which will change the overall supporting strength of the aluminum main frame. The reinforced slider located on the inside of the central inner groove can play a good reinforcement role. Before installation, the secondary connecting rod can be inserted into the inside of the central inner groove so that the reinforced slider on the inside of the central inner groove can be squeezed. After the reinforced slider is pressed, it will slide and squeeze the internal telescopic spring until the reinforced slider fits the sealing sheet, and the reinforced slider squeezes the internal moisture-absorbing cotton block through extrusion.

[0007] According to the above technical scheme, an anti-skid device is provided on the bottom side of the aluminum main frame, and the anti-skid device includes a metal arch plate, a rubber pad, a rubber strip, and an exhaust hole. The metal arch plate is fixedly connected to the bottom side of the aluminum main frame, the rubber pad is arranged on the side of the metal arch plate, the rubber strip is fixedly connected to the surface of the rubber pad, the exhaust hole is opened on the inner side of the through slot, the rubber pad is bonded and connected to the bottom surface of the aluminum main frame, and the exhaust hole penetrates to the interior of the central inner groove. Through the above structure, when the air is discharged outward from the inner side of the central inner groove, it is necessary to first pass through the moisture-absorbing cotton block and be discharged along the exhaust hole. The discharged air will be discharged to both sides along the metal arch plate at the bottom of the aluminum main frame, and a part of the air will be discharged along the through slot on the side of the aluminum main frame, thereby driving the air flow in the through slot to bring out the attachments. While the metal arch plate plays a shielding role on the exhaust hole, it can also allow the discharged moisture to condense on the metal arch plate. Through moisture-proof and moisture-draining, water is prevented from reacting with the aluminum material to cause internal corrosion of the aluminum material, thereby affecting the strength of the corroded part of the aluminum material.

[0008] According to the above technical scheme, inner grooves of the contract strips are provided on both side surfaces of the secondary connecting rod, and side strips of contract strips are provided on the upper and lower sides of the inner groove of the contract strip. The front and rear ends of the secondary connecting rod are fixedly connected with connecting blocks, the upper side surface of the secondary connecting rod is provided with a rod through hole, and the side surface with the connecting block is provided with a splicing side groove. The side surface of the aluminum main frame is symmetrical about the horizontal center of the aluminum main frame, and the outer side surface of the connecting cross bar is provided with a threaded pattern, and the outer side surface of the connecting cross bar is threadedly connected with an installation screw buckle. Through the above structure, since the aluminum main frame is cut from solid material as a whole, and the cut material is divided into a secondary connecting rod, a plug-in connecting plate and a connecting cross bar, the above structure can not only be used as a connecting piece for building a frame, but also the secondary connecting rod can be inserted into the central inner groove in the aluminum main frame, and the plug-in connecting plate can be inserted into the through slot on the side of the aluminum main frame. Before the secondary connecting rod is inserted into the central inner groove, the connecting cross bar can be inserted into the inner side of the secondary connecting rod.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are: The present invention adopts a splicing method to build a frame by arranging an aluminum main frame, a secondary connecting rod, a plug-in connecting plate, a connecting horizontal bar, a rod-penetrating connecting groove, a positioning slot, a positioning convex block, a through slot, a central inner groove, and a convex edge strip, so as to improve the building efficiency. At the same time, different splicing structures between the aluminum main frame, the secondary connecting rod and the plug-in connecting plate can be constructed according to actual use requirements, thereby improving the utilization frequency of the above structure.

[0010] The present invention is provided with a reinforcing slider, a moisture-absorbing cotton block, a sealing sheet, a telescopic spring and a fixed block. By squeezing the reinforcing slider to squeeze the internal moisture-absorbing cotton block, the air inside the reinforcing slider and the fixed block is allowed to carry part of the air and discharge the moisture. Or, by external environmental vibration, such as the vibration of the bottom surface caused by a passing vehicle, the reinforcing slider is allowed to shake, and the reinforcing slider is allowed to hit the inner wall of the central inner groove when shaking, so that the attachments on the outer side of the aluminum main frame are shaken off.

[0011] The present invention is provided with a metal arch plate, a rubber pad, a rubber strip and an exhaust hole to prevent moisture and discharge moisture, thereby preventing water from reacting with aluminum materials to cause internal corrosion of the aluminum materials and affecting the strength of the corroded parts of the aluminum materials. At the same time, in hot weather, the rubber strip on the rubber pad can play an anti-slip role when building in wet weather.

[0012] The present invention, by providing installation screw buckles, connecting plate slots, side strips, connecting blocks, strip inner grooves, rod holes, splicing side grooves, and threaded patterns, achieves structural storage through highly matched structures, facilitates overall transportation, reduces the space required for transportation, and at the same time can reduce the waste of aluminum profile structures and improve the utilization rate of aluminum profile materials.

The frame is constructed in a splicing manner to improve the construction efficiency.

[0016] A protective reinforcement device 5 is provided on the inner side of the aluminum main frame 1, and the protective reinforcement device 5 includes a reinforcement slider 51, a moisture-absorbing cotton block 52, a sealing sheet 53, a telescopic spring 54, and a fixed stopper 55. The reinforcement slider 51 is slidably connected to the inside of the aluminum main frame 1, the moisture-absorbing cotton block 52 is bonded to the inner wall of the aluminum main frame 1, the sealing sheet 53 is fixedly connected to the inner wall of the aluminum main frame 1, the telescopic spring 54 is fixedly connected to the side of the reinforcement slider 51, and the fixed stopper 55 is fixedly connected to the inside of the aluminum main frame 1. The side of the sealing sheet 53 and the side of the reinforcement slider 51 are in contact with each other. The reinforcement slider 51 is located on the inner side of the central inner groove 11, and the fixed stopper 55 is fixedly connected to the telescopic spring 54. The spring 54 is fixedly connected. Through the above structure, since the constructed bracket is often used in outdoor scenes, water is easily accumulated inside the horizontal aluminum main frame 1, and the temperature difference between morning and evening outdoors will cause dew to condense on the outside of the aluminum main frame 1, and enter the internal reinforcement slider 51 and the fixed block 55 through the central inner grooves 11 on both sides to prevent moisture from carrying dust or insects in the internal space and affecting the normal insertion of the internal connection structure of the central inner groove 11. At the same time, when the weather is hot, the aluminum main frame 1 will produce thermal expansion and contraction, which will change the overall supporting strength of the aluminum main frame 1, and the reinforcement slider 51 located on the inner side of the central inner groove 11 can play a good reinforcement role.

[0017] Working principle: When it is necessary to build a platform, the two aluminum main frames 1 can be connected end to end, so that the two aluminum main frames 1 are connected at right angles, and the plug-in connecting plate 3 is inserted into the connecting plate slot 14 on the side of the aluminum main frame 1, and the connecting plate slot 14 is passed through the through slot 10 on the side of the end of the other aluminum main frame 1 to play an auxiliary installation role. When connecting the two vertical aluminum main frames 1, the secondary connecting rod 2 can be inserted into the end of the horizontal aluminum main frame 1, so that the positioning slot 8 at the end of the horizontal aluminum main frame 1 is matched with the side strip 15 of the side of the secondary connecting rod 2, and the positioning protrusion 9 is matched with the inner groove 17 of the strip. It can be quickly assembled by splicing and connecting. When it is necessary to build the top side inclined surface, the secondary connecting rod 2 can be spliced ​​on the vertical aluminum The top side of the aluminum main frame 1, and then the side convex edge strip 12 of another aluminum main frame 1 is fit and spliced ​​with the inner groove 17 of the top side strip of the secondary connecting rod 2, and then the end of the other secondary connecting rod 2 is connected to the side of the horizontal secondary connecting rod 2 here, and the through slot 10 on the side of the horizontal secondary connecting rod 2 here is spliced ​​with the connecting piece block 16. When the structure needs to be processed, the connecting cross bar 4 can be inserted into the through rod connecting groove 7 corresponding to the aluminum main frame 1, and the mounting screw buckles 13 are installed at both ends of the connecting cross bar 4 for reinforcement. The frame is built in a splicing manner to improve the building efficiency. At the same time, the different splicing structures between the aluminum main frame 1, the secondary connecting rod 2 and the plug-in connecting plate 3 can be built according to actual use requirements to improve the utilization frequency of the above structure.

[0018] When the aluminum main frame 1 is used in a horizontal structure, a protective reinforcement device 5 needs to be set inside the aluminum main frame 1. Since the constructed bracket is often used in outdoor scenes, water is easy to accumulate inside the horizontal aluminum main frame 1, and the temperature difference between morning and evening outdoors will cause dew to condense on the outside of the aluminum main frame 1 and enter the inside through the central inner grooves 11 on both sides. By setting a reinforcement slider 51 and a fixed block 55 to block it, it is prevented from moisture carrying dust or insects in the internal space, which affects the normal insertion of the internal connection structure of the central inner groove 11. At the same time, when the weather is hot, the aluminum main frame 1 will produce thermal expansion and contraction, which will cause the overall supporting strength of the aluminum main frame 1 to change, and the reinforcement slider 51 located on the inner side of the central inner groove 11 can It plays a very good reinforcement role. Before installation, the secondary connecting rod 2 can be inserted into the inner side of the central inner groove 11 so that the reinforcing slider 51 inside the central inner groove 11 can be squeezed. After the reinforcing slider 51 is compressed, it will slide to squeeze the internal telescopic spring 54 until the reinforcing slider 51 fits with the sealing sheet 53. By squeezing, the reinforcing slider 51 squeezes the internal moisture-absorbing cotton block 52, while the air inside the reinforcing slider 51 and the fixed block 55 carries part of the air and moisture out, or through external environmental vibrations, such as the vibration of the bottom surface caused by a vehicle passing by, to make the reinforcing slider 51 shake, and let the reinforcing slider 51 hit the inner wall of the central inner groove 11 when shaking, so that the attachments on the outside of the aluminum main frame 1 are shaken off. Embodiment 2

[0019] See also Figure 4-7The present invention provides a technical solution: an anti-skid device 6 is provided on the bottom side of the aluminum main frame 1, and the anti-skid device 6 includes a metal arch plate 61, a rubber pad 62, a rubber strip 63, and an exhaust hole 64. The metal arch plate 61 is fixedly connected to the bottom side of the aluminum main frame 1, the rubber pad 62 is arranged on the side of the metal arch plate 61, the rubber strip 63 is fixedly connected to the surface of the rubber pad 62, and the exhaust hole 64 is opened on the inner side of the through slot 10, the rubber pad 62 is bonded and connected to the bottom surface of the aluminum main frame 1, and the exhaust hole 64 penetrates to the inside of the central inner groove 11. Through the above structure, air flows in the through slot 10 to bring out the attachments, and the metal arch plate 61 not only shields the exhaust hole 64, but also allows the discharged moisture to condense on the metal arch plate 61. Through moisture-proof and moisture-draining, water is prevented from reacting with aluminum to cause internal corrosion of the aluminum, thereby affecting the strength of the corroded part of the aluminum.

[0020] The two side surfaces of the auxiliary connecting rod 2 are provided with inner grooves 17, and the upper and lower sides of the inner grooves 17 are provided with side strips 15. The front and rear ends of the auxiliary connecting rod 2 are fixedly connected with connecting blocks 16. The upper side surface of the auxiliary connecting rod 2 is provided with a rod through hole 18, and the side with the connecting block 16 is provided with a splicing side groove 19. The side surface of the aluminum main frame 1 is symmetrical about the transverse center of the aluminum main frame 1. The outer side surface of the connecting cross bar 4 is provided with a threaded pattern 20, and the outer side surface of the connecting cross bar 4 is threadedly connected with a mounting screw buckle 13. Through the above structure, since the aluminum main frame 1 is cut from solid material as a whole, and the cut material is divided into the auxiliary connecting rod 2, the plug-in connecting plate 3 and the connecting cross bar 4, the above structure can not only be used as a connecting piece for building a frame, but also the auxiliary connecting rod 2 can be inserted into the central inner groove 11 in the aluminum main frame 1, and the plug-in connecting plate 3 can be inserted into the through slot 10 on the side of the aluminum main frame 1. Before the auxiliary connecting rod 2 is inserted into the central inner groove 11, the connecting cross bar 4 can be inserted into the inner side of the auxiliary connecting rod 2.

[0021] Working principle: When the air is discharged outward from the inner side of the central inner groove 11, it needs to first pass through the moisture-absorbing cotton block 52 and be discharged along the exhaust hole 64. The discharged air will be discharged to both sides along the metal arch plate 61 at the bottom of the aluminum main frame 1, and part of the air will be discharged along the through slot 10 on the side of the aluminum main frame 1, thereby driving the air flow in the through slot 10 and taking out the attachments. While the metal arch plate 61 shields the exhaust hole 64, it can also allow the discharged moisture to condense on the metal arch plate 61. Through moisture-proof and moisture-draining, it is prevented that water reacts with aluminum to cause internal corrosion of aluminum and affect the strength of the corroded part of aluminum. At the same time, in hot weather, the rubber strip 63 on the rubber pad 62 can play an anti-slip role when building in humid weather; Since the aluminum main frame 1 is cut from solid material as a whole, and the cut material is divided into the secondary connecting rod 2, the plug-in connecting plate 3 and the connecting cross bar 4, the above structure can not only be used as a connecting piece for building a frame, but also the secondary connecting rod 2 can be inserted into the central inner groove 11 in the aluminum main frame 1, and the plug-in connecting plate 3 can be inserted into the through slot 10 on the side of the aluminum main frame 1. Before the secondary connecting rod 2 is inserted into the central inner groove 11, the connecting cross bar 4 can be inserted into the inner side of the secondary connecting rod 2. The structural storage is achieved through the high fit of the structure, which facilitates the overall transportation and reduces the space occupied by the transportation. At the same time, it can reduce the waste of aluminum profile structure and improve the utilization rate of aluminum profile materials.
