[0001] The utility model relates to the field of aluminum square tubes, in particular to a U-shaped aluminum square tube. Background Art

[0002] Aluminum square tubes are one of the most popular ceiling materials produced in recent years. They offer an open view, ventilation, and air permeability, with crisp, neat lines and distinct layers, reflecting a simple and clear modern style. They are also easy to install and disassemble, making them a popular product in the decoration market in recent years. They are often used in public places with numerous concealed projects and high traffic volume. They facilitate air circulation, exhaust, and heat dissipation, while also distributing light evenly, making the entire space spacious and bright. They are widely used in open spaces such as subways, high-speed rail stations, bus stops, airports, large shopping malls, passageways, leisure venues, public restrooms, hotels, school cafeterias, and building exteriors. However, traditional aluminum square tubes are typically fixed with screws and keels during installation. These screws are often exposed to the outside world, making them susceptible to interference and detrimental to visual aesthetics. Furthermore, the stability of these screws and keels is weak, and there is a risk of them falling off over time. Utility Model Content

[0003] Based on this, the purpose of the present invention is to provide a U-shaped aluminum square tube, which can provide better shielding and hiding functions for the fastening screws, and at the same time provide relatively tight clamping conditions for the shielding plate. In addition, it can also provide a sliding plug-in function for the U-shaped aluminum square and the keel, so that the U-shaped aluminum square tube and the keel have better fastening properties.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a U-shaped aluminum square tube, comprising a U-shaped aluminum square tube and a connecting block, two sets of slide grooves are provided on both sides of the U-shaped aluminum square tube, and baffles are inserted and slidably inserted inside the two sets of slide grooves, and the two ends of the two sets of slide grooves are respectively inserted and engaged with abutment blocks, two sets of snap-fitting plates are fixed inside the U-shaped aluminum square tube, and two sets of snap-fitting grooves are provided on both sides of the interior of the connecting block.

[0005] By adopting the above technical solution, the U-shaped aluminum square tube is connected to the two sets of snap-in grooves on both sides of the connecting block through the snap-in plates. The sliding grooves on both sides of the U-shaped aluminum square tube are used for sliding and plugging the baffle, and then cooperate with the limiting function of the block to shield, protect and beautify the first screw.

[0006] Furthermore, a plurality of groups of first through holes are formed at equal intervals on both sides of the U-shaped aluminum square tube, and first screws are inserted into the interiors of the plurality of groups of first through holes.

[0007] By adopting the above technical solution, the multiple groups of first through holes on both sides of the U-shaped aluminum square tube are used to provide installation space for multiple groups of first screws.

[0008] Furthermore, a plurality of groups of second through holes are provided inside the connection block, and the plurality of groups of second through holes are arranged corresponding to the plurality of groups of first through holes, and the second through holes are threadedly connected to the first screws.

[0009] By adopting the above technical solution, the several groups of second through holes opened inside the connecting block are arranged corresponding to the first through holes on the U-shaped aluminum square tube, ensuring that the first screw can smoothly pass through the first through hole and be threadedly connected with the second through hole.

[0010] Furthermore, the abutment blocks are made of rubber material to increase the friction between them and the slide groove, and the two groups of abutment blocks are tightly pressed against both ends of a group of baffles.

[0011] By adopting the above technical solution, the stop blocks are made of rubber material, which increases the friction between them and the slide groove. The two groups of stop blocks are tightly pressed against the two ends of a group of baffles. This design enables the baffles to be stably fixed in the slide groove and will not move due to external force.

[0012] Furthermore, a keel is fixed to the top of the connecting block, and a plurality of groups of second screws are provided on the top of the keel for fastening to the external ceiling.

[0013] By adopting the above technical solution, a keel is fixed on the top of the connecting block, making the entire U-shaped aluminum square tube more stable. Several groups of second screws are provided on the top of the keel for fastening to the external ceiling, so that the U-shaped aluminum square tube can be firmly installed on the ceiling and is not prone to falling off or loosening.

[0014] Furthermore, the engaging piece and the engaging slot are slidably engaged with each other, and the contact surfaces of the engaging piece and the engaging slot are smooth.

[0015] By adopting the above technical solution, the snap-in piece and the snap-in groove are slidably engaged with each other, making the connection between the U-shaped aluminum square tube and the connecting block more flexible and convenient. The contact surfaces of the snap-in piece and the snap-in groove are smooth. This design reduces the friction between the two and makes the sliding plug-in process smoother.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. The utility model provides a baffle so that the baffle can be inserted and slid inside the slide grooves on both sides of the U-shaped aluminum square tube, thereby providing a shielding function for the first screw, improving the aesthetics of the outer side of the U-shaped aluminum square tube, and at the same time providing a protection function for the first screw connecting the U-shaped aluminum square tube and the connecting block;

[0018] 2. The utility model provides a stop block, which can be plugged and engaged with the slide grooves on both sides of the U-shaped aluminum square tube, thereby providing a fastening and limiting function at both ends of the baffle. At the same time, the stop block is made of rubber material, which provides good friction when plugged and engaged with the slide grooves on both sides of the U-shaped aluminum square tube, thereby providing stability;

[0019] 3. The utility model provides a snap-in piece and snap-in grooves on both sides of the connecting block, so that the U-shaped aluminum square tube can be slidably plugged into the snap-in grooves on both sides of the connecting block through the snap-in piece, thereby making the U-shaped aluminum square tube and the connecting block have better connection fastening, and preventing the U-shaped aluminum square tube from falling off due to loosening of the first screw after being used for too long.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] In this embodiment:

[0030] A U-shaped aluminum square tube, such as Figure 1-Figure 4 As shown, it includes a U-shaped aluminum square tube 1 and a connecting block 8. Two sets of slide grooves 3 are opened on both sides of the U-shaped aluminum square tube 1, and baffles 6 are slidably inserted inside the two sets of slide grooves 3. The two ends of the two sets of slide grooves 3 are respectively inserted and engaged with blocks 7. Two sets of card pieces 2 are fixed inside the U-shaped aluminum square tube 1, and two sets of card grooves 9 are opened on both sides of the interior of the connecting block 8.

[0031] Among them, the ingenious design of the U-shaped aluminum square tube 1 and the connecting block 8, as well as the precise coordination of the snap-in piece 2 and the snap-in groove 9, realize the rapid installation and stable connection of the ceiling assembly. By opening the sliding groove 3 on both sides of the U-shaped aluminum square tube 1 and slidingly inserting the baffle 6, and then cooperating with the limiting effect of the block 7, the first screw 5 and other connecting parts are effectively shielded, protected and beautified.

[0032] See Figure 2 and Figure 4 , a plurality of groups of first through holes 4 are evenly spaced on both sides of the U-shaped aluminum square tube 1, and first screws 5 are inserted into the interior of the plurality of groups of first through holes 4;

[0033] The insertion of multiple sets of first screws 5 further enhances the connection stability between the U-shaped aluminum square tube 1 and the connecting block 8 .

[0034] See Figure 2 、 Figure 3 and Figure 4 , a plurality of groups of second through holes 10 are opened inside the connecting block 8, and the plurality of groups of second through holes 10 are arranged corresponding to the plurality of groups of first through holes 4, and the second through holes 10 are threadedly connected to the first screws 5;

[0035] The threaded connection between the second through hole 10 and the first screw 5 further enhances the connection stability between the U-shaped aluminum square tube 1 and the connecting block 8 .

[0036] See Figure 1 and Figure 2, the block 7 is made of rubber material to increase the friction between it and the slide 3, and the two sets of blocks 7 are tightly pressed against both ends of a set of baffles 6;

[0037] Among them, the rubber material has good elasticity and friction, so that the block 7 can be firmly fixed after being inserted into the slide groove 3, and is not easy to slide or fall off. The tightening effect of the block 7 also effectively seals the gap between the baffle 6 and the U-shaped aluminum square tube 1, preventing dust and other debris from entering the interior.

[0038] See Figure 1 、 Figure 2 and Figure 3 , a keel 11 is fixed to the top of the connecting block 8, and a plurality of groups of second screws 12 are provided on the top of the keel 11 for fastening to the external ceiling;

[0039] The keel 11 is the main supporting structure of the entire facility, and its stability is directly related to the safety of the entire equipment. Several groups of second screws 12 can provide better stability for the keel 11 .

[0040] See Figure 1 、 Figure 2 and Figure 4 , the card piece 2 and the card slot 9 are slidably engaged, and the contact surfaces of the card piece 2 and the card slot 9 are smooth;

[0041] Among them, the U-shaped aluminum square tube 1 is slidably plugged into the internal snap-in grooves 9 on both sides of the connecting block 8 through the snap-in piece 2 to complete the connection between the two. The contact surfaces of the snap-in piece 2 and the snap-in groove 9 are smooth, which can also reduce wear and extend the service life of the ceiling system.

[0042] The implementation principle of the present invention is as follows: first, the U-shaped aluminum square tube 1 is slidably plugged into the internal snap-in grooves 9 on both sides of the connecting block 8 through the snap-in piece 2, so that the U-shaped aluminum square tube 1 is limitedly engaged with the connecting block 8 through the snap-in piece 2, and while the U-shaped aluminum square tube 1 is connected to the connecting block 8, the several groups of first through holes 4 opened on the surfaces of both sides of the U-shaped aluminum square tube 1 and the several groups of second through holes 10 opened inside the connecting block 8 are sequentially arranged correspondingly, and then the first screws 5 are passed through the first through holes 4 and then threadedly fastened to the second through holes 10, so that the U-shaped aluminum square tube 1 and the connecting block 8 have better connection stability. When the first screws 5 are screwed in, the U-shaped aluminum square tube 1 and the connecting block 8 have better connection stability. After installation, slide the two groups of baffles 6 into the interior of the slide grooves 3 opened on both sides of the U-shaped aluminum square tube 1, so that the two groups of baffles 6 can provide shielding, protection and beautification functions for the first screws 5 on both sides of the U-shaped aluminum square tube 1, and then divide the four groups of retaining blocks 7 into two groups to insert the two ends of the slide grooves 3 on both sides, so that the retaining blocks 7 can provide the baffles 6 with the function of limiting and fastening to prevent the slide groove 3 from falling off when it is used again. The material of the retaining block 7 is rubber, which can increase the friction between it and the slide groove 3. Finally, the connecting block 8 is connected and fastened to the external ceiling through several groups of second screws 12 on the top of the keel 11 that is integrated with it, and the existing installation method is used.
