Description

Technical Field

[0001] The present invention relates to the technical field of building material installation, and particularly to an aluminum plate with an adjustable angle code. Background Art

[0002] Aluminum gusset plates are a special material, light in texture and durable, and are widely used in home decoration ceilings. They have various excellent properties and are suitable for kitchens and bathrooms. They can not only achieve good decorative effects but also have multiple functions. Existing aluminum gusset plates are mainly fixedly connected to ceiling keels through screws.

[0003] However, the traditional screw fixation method meets the installation requirements to a certain extent, but there are also some deficiencies: usually, self-tapping screws are used to fix the aluminum single plate to the ceiling keel. It is necessary to accurately align the position before fixing. In order to ensure the stability and load-bearing capacity of the aluminum single plate, multiple screw fixation points are usually required. Since it is necessary to align the position and tighten the screws one by one, the disassembly and assembly process is relatively cumbersome, affecting the overall installation efficiency.

[0004] In addition, multiple screws are required for fastening connection between the aluminum plate and the keel. The entire installation process requires holding the aluminum plate for a long time, which is relatively laborious. In addition, the traditional installation method requires leaving an inspection opening for the aluminum plate that is not tightly connected to the keel. This aluminum plate has relatively poor connection stability compared to other aluminum plates. Therefore, an aluminum plate with an adjustable angle code is proposed. Summary of the Invention

Detailed implementation manners

[0032] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-12, the present invention provides a technical solution: an aluminum plate with adjustable corner codes, including a keel main body 1. The keel main body 1 includes a plurality of main keels 11 and auxiliary keels 12 distributed horizontally and vertically. A plurality of buckle plates 2 distributed in a rectangular shape are installed inside the plurality of main keels 11 and auxiliary keels 12 distributed horizontally and vertically. The buckle plates 2 are connected to the main keels 11 and the auxiliary keels 12 through a plurality of groups of adjusting mechanisms 3 and quick installation and disassembly components 4. The quick installation and disassembly components 4 are fixedly connected to the keel main body 1. The adjusting mechanism 3 includes an L-shaped corner code one 32. The L-shaped corner code one 32 is fixedly connected to the buckle plate 2, and the L-shaped corner code one 32 is detachably connected to the quick installation and disassembly component 4.

[0034] The quick installation and disassembly component 4 includes an installation box 41. One side and the bottom of the installation box 41 are open. Ear plates 46 are fixedly installed on both sides of the installation box 41. Rectangular openings 43 are formed on the inner walls of both sides of the installation box 41. A clamping column 44 is rotatably installed in the rectangular opening 43. Claw slots 321 adapted to the clamping column 44 are formed on both sides of the L-shaped corner code one 32.

[0035] Furthermore, the ear plates 46 are fixedly connected to the main keel 11 through fasteners, and the ear plates 46 are also fixedly connected to the auxiliary keel 12 through fasteners. During installation, the staff first fixedly installs the L-shaped corner code one 32 on the buckle plate 2 in advance, and makes the plurality of L-shaped corner codes one 32 lie in the same plane and be in a horizontal state with respect to the buckle plate 2. When encountering a keel main body 1 with low flatness, the installer only needs to adjust the position height of the quick installation and disassembly components 4 installed on the main keel 11 and the auxiliary keel 12 to make the plurality of quick installation and disassembly components 4 lie in the same horizontal plane. Then, insert the plurality of L-shaped corner codes one 32 on the buckle plate 2 into the corresponding quick installation and disassembly components 4, and it can be ensured that even when installing the buckle plate 2 on a keel main body 1 with low flatness, the buckle plate 2 can still be in a horizontal state.

[0036] Rectangular boxes 42 with the same-side openings as the installation box 41 are fixedly installed on both sides of the installation box 41. One side of the two rectangular boxes 42 close to each other is open. The two rectangular boxes 42 are respectively communicated with the corresponding rectangular openings 43. Magnet blocks 442 are fixedly installed on the inner walls of the two rectangular boxes 42 far from each other. Magnet sheets 441 are fixedly installed in an embedded manner on the sides of the two clamping columns 44 far from each other. The magnetic poles of the sides of the magnet block 442 and the magnet sheet 441 close to each other on the same side are opposite. A round shaft 446 is fixedly installed on one side of the clamping column 44. The round shaft 446 penetrates through the installation box 41 and is rotatably connected to the installation box 41.

[0037] Furthermore, when the L-shaped corner code one 32 is not connected to the installation box 41, the clamping column 44 is in a vertical state, and the magnet sheets 441 and 441 connected by magnetic attraction remain vertical.

[0038] A spring ring 47 is fixedly mounted on the top inner wall of the installation box 41 , and an arc block 45 matched with the clamping column 44 is fixed on the bottom inner wall of the rectangular box 42 .

[0039] Furthermore, the arc block 45 abuts against the bottom end of the clamping column 44 , so it can support the clamping column 44 and prevent the single circular shaft 446 from failing to position the clamping column 44 .

[0040] A T-shaped slot 443 is formed on one side of the two ear plates 46 that are close to each other. Two clamping edges 444 and two pushing edges 445 are formed on the T-shaped slot 443 .

[0041] An abutting edge 322 is provided on the top inner wall of the slot 321, and a receiving slot 323 is provided on both sides of the L-shaped corner code 32. The bottom inner wall of the receiving slot 323 is a sloped edge 324. A pushing mechanism 48 is provided in the receiving slot 323, and the pushing mechanism 48 includes a rotating shaft 4810 rotatably connected to the inner walls on both sides of the receiving slot 323. A rotating block 481 is rotatably sleeved on the rotating shaft 4810. Two symmetrically distributed latches 484 are slidably installed on one side of the rotating block 481 close to the side opening of the receiving slot 323. The latches 484 are provided with a hook portion 486 and an inclined portion 485.

[0042] The same shaft rod 488 is slidably installed on the two latch tongues 484, and connecting plates 487 fixedly connected to the rotating block 481 are fixedly installed at both ends of the shaft rod 488. A return spring 489 sleeved on the shaft rod 488 is fixedly installed between the two latch tongues 484. An arc rod 482 is movably installed through the rotating block 481, and both ends of the arc rod 482 are fixedly connected to the inner wall of one side of the accommodating groove 323. Two return springs 483 are sleeved on the arc rod 482, and the two return springs 483 are respectively arranged on the top and bottom of the rotating block 481, and the two ends of the return spring 483 are respectively fixedly connected to the rotating block 481 and the inner wall of the accommodating groove 323.

[0043] In this embodiment, when assembling the L-shaped angle bracket 32 ​​and the installation box 41, it is only necessary to insert the L-shaped angle bracket 32 ​​from the bottom to the top through the bottom opening of the installation box 41. When the latches 484 on the pushing mechanism 48 on both sides of the L-shaped angle bracket 32 ​​contact the bottom of the installation box 41, as the L-shaped angle bracket 32 ​​moves upward, the entire pushing mechanism 48 will rotate with the rotating shaft 4810 as the center of the circle and compress the return spring 483 located below to completely store itself in the receiving groove 323. After that, the L-shaped angle bracket 32 ​​can be normally inserted into the installation box 41.

[0044] Subsequently, the top of the first L-shaped angle code 32 will contact the spring coil 47. As the first L-shaped angle code 32 continues to move upward, the spring coil 47 will be compressed. When the abutting edges 322 on the two card slots 321 move above the corresponding card posts 44, the two receiving grooves 323 will also communicate with the corresponding rectangular openings 43. At this time, the bottom end of the tongue 484 will be above the inner wall of the bottom of the rectangular opening 43. Then, under the restoring elastic force of the compressed first restoring spring 483 and the other stretched first restoring spring 483, the pushing mechanism 48 originally retracted in the receiving groove 323 will pop out, and the two tongues 484 will push the lower half of the card post 44, causing the card post 44 to rotate around the center of the round shaft 446, and the magnet sheet 441 and the magnet block 442 to separate. After the upper half of the rotating card post 44 enters the card slot 321, release the first L-shaped angle code 32. Under the restoring elastic force of the compressed spring coil 47, the first L-shaped angle code 32 will be pushed downward, and the tops of the two first card edges 444 will respectively abut against the two abutting edges 322. At this time, the first L-shaped angle code 32 is tightly connected to the quick assembly and disassembly component 4;

[0045] When it is necessary to separate the first L-shaped angle code 32 from the quick assembly and disassembly component 4, just push the first L-shaped angle code 32 upward again. At this time, the upward movement of the ramp edge 324 will cause the card post 44 to rotate and tend to be in a vertical state. The two hooking parts 486 respectively abut against the two pushing edges 445. Then, as the first L-shaped angle code 32 drives the pushing mechanism 48 to move upward, during the rotation of the card post 44, under the action of the two pushing edges 445, the two tongues 484 will be pushed closer to each other. At this time, the two tongues 484 will also simultaneously extend into the T-shaped groove 443. When the card post 44 returns to the vertical state, the two tongues 484 will completely extend into the T-shaped groove 443. Then, under the restoring elastic force of the compressed second restoring spring 489, the two tongues 484 will move away from each other, and at the same time, the two tongues 484 will respectively hook the two first card edges 444;

[0046] Subsequently, since the card post 44 no longer blocks the rectangular opening 43 after being vertical, just pull down the first L-shaped angle code 32. During this process, when the tongue 484 on the pushing mechanism 48 contacts the inner wall of the bottom of the rectangular opening 43, at this time, the downward movement of the rectangular opening 43 is resisted. At this time, just increase the downward pulling force on the first L-shaped angle code 32, and the entire pushing mechanism 48 will rotate around the rotating shaft 4810 and completely retract into the receiving groove 323 by compressing the first restoring spring 483 located above, then the first L-shaped angle code 32 can be pulled down to completely separate it from the installation box 41.

[0047] Embodiment 1

[0048] C-shaped bending edges 21 are provided on the four sides around the buckle plate 2. The adjusting mechanism 3 includes a flat angle code 31 fixedly connected to the top of the C-shaped bending edge 21, and the flat angle code 31 is detachably connected to the first L-shaped angle code 32.

[0049] Further, such as Figure 2 , Figure 4 As shown, the flat angle code 31 and the C-shaped bent edge 21 are fixedly connected by fasteners, the horizontal flat angle code 31 and the horizontal part of the L-shaped angle code 32 are also fixedly connected by fasteners, and the flat angle code 31 and the L-shaped angle code 32 are transitionally connected by an elastic pad. The C-shaped bent edge 21 forms a reinforcing rib around the gusset plate 2, which can improve the deformation resistance of the gusset plate 2, can effectively prevent the gusset plate 2 from deformation, and can improve the flatness and strength of the gusset plate 2.

[0050] Example 2

[0051] The gusset plate 2 is provided with U-shaped bending edges 22 on all sides, and the adjustment mechanism 3 includes an L-shaped corner code 2 33 fixedly connected to the U-shaped bending edge 22, and the L-shaped corner code 2 33 and the L-shaped corner code 1 32 are detachably connected.

[0052] Further, such as Figure 3 , Figure 5 As shown, the L-shaped corner code 2 33 and the U-shaped bending edge 22 are fixedly connected by fasteners, and the horizontal part of the L-shaped corner code 2 33 and the horizontal part of the L-shaped corner code 1 32 are also fixedly connected by fasteners. The L-shaped corner code 2 33 and the L-shaped corner code 1 32 are transitionally connected by an elastic pad, and the U-shaped bending edge 22 forms a reinforcing rib around the C-shaped bending edge 21, which can improve the deformation resistance of the gusset plate 2, can effectively prevent the gusset plate 2 from deformation, and can improve the flatness and strength of the gusset plate 2.

[0053] Furthermore, by extending the length of each side of the flat angle code 31, L-shaped angle code 1 32 and L-shaped angle code 2 33, as well as extending the length of each bending edge of the C-shaped bending edge 21 and the U-shaped bending edge 22, not only is the assembly and installation of the entire equipment facilitated, but also the appearance and overall strength of the gusset plate 2 can be improved.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
