Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a novel aluminum building self-locking connection component. Background Technology

[0002] In the construction industry, aluminum building materials are widely used in various building structures due to their advantages such as light weight, corrosion resistance, and ease of processing. However, the connection problem between aluminum building materials has always been one of the key factors restricting its further application.

[0003] Traditional methods of connecting aluminum building materials, such as welding, riveting, or bolting, can achieve material connection to a certain extent, but they also have corresponding problems. Bolting requires multiple tightening operations, resulting in low construction efficiency and inconvenient disassembly; welding can easily damage the surface treatment layer of the material, affecting its corrosion resistance.

[0004] While some existing snap-fit ​​connectors can simplify installation, they generally have two major drawbacks: first, the connection angle is fixed and cannot adapt to non-vertical splicing scenarios; second, the locking mechanism is prone to loosening due to vibration, which can easily lead to insufficient connection stability. Utility Model Content

[0005] The purpose of this utility model is to provide a novel aluminum building self-locking connection component. In this utility model, the connection component realizes multi-angle free adjustment and rigid locking of the locking frame, which can adapt to different splicing angles. When the locking frame is inserted, it is automatically locked by the inclined plane driving the torsion spring rod. The self-locking is completed by a single push, which is simple and quick to operate. The second screw forms an anti-loosening mechanical limit. When unlocking, the component can be separated by removing the screw and moving the lever. It supports non-destructive disassembly and assembly, is convenient to use, and solves the existing technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A new type of aluminum building self-locking connection assembly includes:

[0008] Multiple connector bodies are provided, each of which is used for fixed installation on one side of a corresponding aluminum building material. Two adjacent connector bodies cooperate with each other to connect two aluminum building materials. Each connector body includes a mounting plate, a locking box, a rotating bracket, a rotating block, and a locking frame.

[0009] The rotating bracket is fixedly connected to the top of the locking box;

[0010] The locking frame is fixedly connected to the top of the rotating block;

[0011] The rotating block is rotatably connected to the rotating bracket to achieve angle adjustment of the locking frame;

[0012] The locking box is equipped with a locking component, which is used to engage and lock with the locking frame of the adjacent connecting body.

[0013] Optionally, a fixing ring and multiple arc-shaped fastening plates are respectively provided on both sides of the rotating bracket, and the fixing ring and multiple arc-shaped fastening plates are all fixedly connected to the rotating bracket;

[0014] Multiple arc-shaped fastening plates are arranged in a ring to form a ring body, and correspond to the fixing ring;

[0015] The rotating block is sleeved on the outer wall of the rotating bracket, one end of the fixing ring rotatably passes through one side of the rotating block, and one end of the ring formed by the plurality of arc-shaped fastening plates rotatably passes through the other side of the rotating block.

[0016] A first screw is provided through one side of the rotating block. One end of the first screw passes through the fixing ring and abuts against the inner wall of multiple arc-shaped fastening plates. One end of the first screw is threadedly connected to the rotating bracket.

[0017] Optionally, the inner walls of the arc-shaped fastening plates are provided with inclined surfaces, and the thickness of the arc-shaped fastening plates gradually increases in the direction away from the rotating bracket.

[0018] The first screw is used to press the inner wall slope of multiple arc-shaped fastening plates, causing one end of the annular body to expand to increase the friction with the inner wall of the rotating block, thereby locking the angle of the rotating block.

[0019] Optionally, the locking assembly includes a rotating shaft rotatably mounted on the inner wall of the locking box, and two torsion springs are sleeved on the outer wall of the rotating shaft. One end of each torsion spring is fixedly connected to the outer wall of the rotating shaft through a spring seat, and the other end of each torsion spring is fixedly connected to the inner wall of the locking box through a spring seat.

[0020] A connecting rod is fixedly connected to the outer wall of the rotating shaft, and a locking rod is fixedly connected to the other end of the connecting rod;

[0021] The bottom of the locking box has two mounting through holes, and the two top ends of the locking frame slide through the corresponding mounting through holes and extend into the locking box.

[0022] Optionally, both top ends of the locking frame are provided with inclined surfaces, which are used to drive the locking rod to rotate and compress the torsion spring when the locking frame is inserted into the locking box;

[0023] A slot is provided on one side of the locking frame. When the locking rod is aligned with the slot, the torsion spring rebounds and causes the locking rod to engage in the slot, thus completing the locking.

[0024] Optionally, both ends of the locking lever are fixedly connected to levers, and both sides of the locking box are provided with arc-shaped grooves. One end of each of the two levers passes through the adjacent arc-shaped grooves and slides in cooperation with the inner wall of the arc-shaped grooves, for moving the locking levers from the outside to unlock the locking frame.

[0025] Optionally, a second screw is threaded through one side of the locking box, and one end of the second screw is used to abut against the locking rod after the locking rod is engaged, so as to form an anti-loosening mechanical limit.

[0026] Optionally, the mounting plate is fixedly connected to one side of the locking box, and the mounting plate has multiple mounting holes on one side for fixing the main body of the connector to the surface of the aluminum building material.

[0027] The embodiments of this utility model have the following beneficial effects:

[0028] In this utility model, the locking frame can be freely rotated at multiple angles by the cooperation of the rotating bracket and the rotating block; when the first screw is tightened, it squeezes the ring-shaped fastening plate, which expands its inclined surface and increases the friction with the inner wall of the rotating block, so as to realize stepless angle adjustment and rigid locking, which can adapt to the splicing requirements of aluminum materials with different tilt angles.

[0029] In this invention, when the locking bracket is inserted into an adjacent locking box, its top inclined surface pushes the locking rod to rotate and compresses the torsion spring; when the locking rod is aligned with the slot, the torsion spring automatically rebounds to lock it in place, thus achieving locking with a single push; this process requires no auxiliary tools and significantly improves installation efficiency.

[0030] In this utility model, after the locking lever is engaged, the second screw can be screwed in to tighten the back of the locking lever, forming a mechanical limit and preventing vibration from causing accidental unlocking;

[0031] In this utility model, unlocking only requires unscrewing the second screw and moving the lever in the arc groove with your finger to disengage the locking lever from the groove. Pulling out the locking frame in the opposite direction completes the separation. The operation is simple and does not damage any components. It supports repeated disassembly and assembly.

[0032] In this invention, the ring-shaped body formed by the fixing ring and the multi-arc fastening plate disperses the force and avoids stress concentration at a single point; the synchronous lever design at both ends of the lever ensures smooth unlocking action and avoids uneven load wear; the overall component structure is simple, easy to install, and can ensure the integrity of the aluminum surface.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0043] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0044] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0045] Example 1: Please refer to Figure 1-6 As shown, this embodiment provides a connecting assembly, which mainly consists of multiple connector bodies 1, which are fixedly installed on one side of the corresponding aluminum building material. The connection between the two aluminum building materials is achieved through the mutual cooperation of two adjacent connector bodies 1.

[0046] Each connector body 1 consists of a mounting plate 2, a locking box 3, a rotating bracket 4, a rotating block 5, and a locking frame 7.

[0047] In this embodiment, the rotating bracket 4 is fixedly installed on the top of the locking box 3. A fixing ring 16 and multiple arc-shaped fastening plates 17 are respectively provided on both sides of the rotating bracket 4, and both the fixing ring 16 and the multiple arc-shaped fastening plates 17 are fixedly connected to the rotating bracket 4. The multiple arc-shaped fastening plates 17 are arranged in a ring to form a ring shape, and correspond to the fixing ring 16. The rotating block 5 is sleeved on the outer wall of the rotating bracket 4. One end of the fixing ring 16 rotates through one side of the rotating block 5, and one end of the ring shape formed by the multiple arc-shaped fastening plates 17 rotates through the other side of the rotating block 5. A first screw 6 is provided through one side of the rotating block 5. One end of the first screw 6 is threadedly connected to the rotating bracket 4, and the other end of the first screw 6 passes through the fixing ring 16 and abuts against the multiple arc-shaped fastening plates 17.

[0048] Furthermore, in this embodiment, the inner walls of the multiple arc-shaped fastening plates 17 are all provided with inclined surfaces, and the thickness of the arc-shaped fastening plates 17 gradually increases in the direction away from the rotating bracket 4. When it is necessary to adjust the angle of the locking frame 7, the first screw 6 is loosened first. At this time, the rotating block 5 can rotate freely relative to the rotating bracket 4, driving the locking frame 7 to rotate together, thereby realizing the adjustment of the angle of the locking frame 7. After the angle is adjusted to the appropriate position, the first screw 6 is tightened. As the first screw 6 is tightened, it is pressed against the inner walls of the multiple arc-shaped fastening plates 17, causing one end of the annular body to expand, thereby increasing the friction between the annular body and the inner wall of the rotating block 5, ultimately locking the rotating block 5, and thus fixing the angle of the locking frame 7.

[0049] In this embodiment, the locking frame 7 is detachably fixed to the top of the rotating block 5 by fixing screws. The rotating block 5 is rotatably connected to the rotating bracket 4, thereby realizing the adjustability of the angle of the locking frame 7. A locking assembly is provided inside the locking box 3. The locking assembly includes a rotating shaft 9 rotatably mounted on the inner wall of the locking box 3. Two torsion springs 10 are sleeved on the outer wall of the rotating shaft 9. One end of each torsion spring 10 is fixedly connected to the outer wall of the rotating shaft 9 through a spring seat, and the other end of each torsion spring 10 is fixedly connected to the inner wall of the adjacent locking box 3 through a spring seat. A connecting rod 11 is fixedly installed on the outer wall of the rotating shaft 9, and a locking rod 12 is fixedly installed on the other end of the connecting rod 11.

[0050] Furthermore, in this embodiment, the bottom of the locking box 3 has two mounting through holes 8, and the two top ends of the locking frame 7 slide through the corresponding mounting through holes 8 and extend into the locking box 3. Both top ends of the locking frame 7 have inclined surfaces that cooperate with the locking rod 12. A slot 18 is provided on one side of the locking frame 7. When two adjacent connecting body 1s approach each other, the top end of the locking frame 7 enters the locking box 3 through the mounting through holes 8, and the inclined surface of its top end contacts the locking rod 12 and pushes the locking rod 12 to rotate, while the torsion spring 10 deforms. As the top end of the locking frame 7 continues to penetrate deeper, the locking rod 12 resets under the elastic force of the torsion spring 10 and engages in the slot 18 of the locking frame 7, thereby completing the locking of the locking box 3 and the adjacent locking frame 7, realizing the connection and locking of the two connecting body 1s.

[0051] This application can be used in the field of building construction technology, or in other fields applicable to this application.

[0052] Example 2: Reference Figure 2 , 3 5. Improvement based on Example 1: A new type of aluminum building self-locking connection component, which is applied to the field of building construction technology;

[0053] In this embodiment, to facilitate the user's external manipulation of the locking lever 12 to unlock the locking frame 7, levers 13 are fixedly installed at both ends of the locking lever 12. Arc-shaped grooves 14 are provided on both sides of the locking box 3. One end of each lever 13 passes through an adjacent arc-shaped groove 14 and slides against the inner wall of the corresponding arc-shaped groove 14. When unlocking is required, the user simply moves the lever 13 to disengage the locking lever 12 from the locking groove 18, thus releasing the lock.

[0054] Furthermore, in this embodiment, a second screw 15 is threaded through one side of the locking box 3, and one end of the second screw 15 engages with the locking rod 12. After the locking rod 12 engages with the locking groove 18, the second screw 15 is tightened so that one end of it abuts against the locking rod 12, thereby limiting the locking rod 12 in the engaged state and preventing the locking rod 12 from accidentally coming out of the locking groove 18, further improving the stability of the connection.

[0055] In this embodiment, the mounting plate 2 is fixedly installed on one side of the locking box 3, and multiple mounting holes are provided on it. Through these mounting holes, using appropriate fasteners such as bolts, the main body 1 of the connector can be firmly fixed to the surface of the corresponding building material, ensuring a stable connection between the main body 1 of the connector and the building material.

[0056] The usage process and working principle of this utility model technical solution are as follows:

[0057] In use, the connector body 1 can be fixed to the edge of the corresponding aluminum building material. Then, the angle of the locking bracket 7 can be adjusted according to the required mating angle between adjacent building materials.

[0058] During adjustment, loosen the first screw 6. At this time, the rotating block 5 can rotate around the rotating bracket 4. After the locking frame 7 rotates to the desired angle, tighten the first screw 6 again. The first screw 6 is threaded to the rotating bracket 4, and one end of it passes through the annular body formed by the fixing ring 16 and multiple arc-shaped fastening plates 17 in sequence. During the tightening process, the shank of the first screw 6 exerts an outward wedge-shaped compression force on the arc-shaped inner wall slope of the multiple arc-shaped fastening plates 17, thereby forcing the end of the annular body to expand outward. This expansion significantly increases the friction between the annular body and the inner wall of the rotating block 5, thereby firmly locking the rotating block 5 in the current position and preventing it from rotating accidentally, thus completing the angle adjustment and pre-fixing of the locking frame 7.

[0059] After the two aluminum building materials that need to be connected are each fixed with their connector bodies 1 and the angle is pre-adjusted, bring the two adjacent connector bodies 1 closer to each other. Then push the locking bracket 7 of one of the connector bodies 1 so that its two top ends are respectively inserted into the two mounting through holes 8 at the bottom of the locking box 3 of the adjacent connector body 1, and slide into the locking box 3.

[0060] During insertion, the inclined surface at the top of the locking frame 7 will first contact and push the locking lever 12 inside the locking box 3. The locking lever 12, under the squeezing action of the inclined surface, overcomes the preload of the torsion springs 10 at both ends and rotates around the rotating shaft 9 at a certain angle, allowing the locking frame 7 to continue to penetrate deeper into the locking box 3.

[0061] When the locking frame 7 moves until the locking rod 12 aligns with the corresponding slot 18, the locking rod 12 can accurately engage with the slot 18 on one side of the locking frame 7 under the restoring force of the torsion spring 10, forming a secure engagement. This engagement action can reliably lock the two connecting body 1s together, thereby completing the connection of the two aluminum building materials.

[0062] To ensure a stable locking state, the second screw 15 on one side of the locking box 3 can be further tightened. After the second screw 15 is screwed in, its end abuts against the latch 12 which is in the locked state, effectively limiting the latch 12 and preventing it from accidentally coming out of the slot 18 under external force or vibration, thus greatly enhancing the reliability of the connection and locking.

[0063] When disassembly is required, first loosen the second screw 15 to release its restriction on the locking lever 12. Then, the user can simultaneously move the levers 13 at both ends of the locking lever 12 from the outside using their fingers or tools through the arc-shaped grooves 14 on both sides of the locking box 3. Moving the levers 13 will force the locking lever 12 to rotate against the elastic force of the torsion spring 10, thereby disengaging its rod from the slot 18 on the locking frame 7.

[0064] Once the lever 12 disengages from the slot 18, the locking bracket 7 can be smoothly pulled out from the mounting through hole 8 of the locking box 3, thereby unlocking and separating the two connecting body 1s.
