Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to an adjustable aluminum alloy profile roof frame. Background Technology

[0002] In the field of building engineering, aluminum alloy profile roof frames are widely used in temporary exhibition halls, storage facilities and outdoor sunshade structures due to their lightweight, high strength and corrosion resistance.

[0003] The frame has a fixed length and needs to be modified by cutting or welding to adapt to different span requirements, resulting in material waste and extended construction period.

[0004] The technical solution of this device addresses the above-mentioned shortcomings by using mechanical self-locking positioning and dual-track guiding design to achieve high precision, low cost, and easy operation and adjustment of the roof frame, filling the gap in existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable aluminum alloy profile roof frame. Through mechanical self-locking and dual-track guiding design, the roof frame achieves high precision, low cost, and easy operation and adjustment, filling the gap in the prior art and solving existing technical problems.

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

[0007] An adjustable aluminum alloy profile roof frame, used to adjust the roof's range after installation, includes:

[0008] Two longitudinal beams, with multiple crossbeams welded to the top of the two longitudinal beams, and the two longitudinal beams and multiple crossbeams forming a roof frame;

[0009] Each of the longitudinal beams includes an extension beam, a fixed beam, and an adjusting beam. One end of the adjusting beam is welded and fixed inside the extension beam, and the other end of the adjusting beam is slidably disposed inside the fixed beam. A set of guide components is provided between the adjusting beam and the fixed beam, and the guide components are used to limit and guide the movement of the adjusting beam.

[0010] Furthermore, in order to ensure that the adjusting beam remains stable after moving within the fixed beam, a set of positioning components is provided between the adjusting beam and the fixed beam. The positioning components are used to engage and position the adjusting beam with the fixed beam after it moves.

[0011] The adjusting beam is equipped with a set of driving components, which are used to temporarily release the locking and positioning of the fixed beam and the adjusting beam so as to move the extension beam and the adjusting beam.

[0012] Optionally, each set of guide components includes two limiting rods formed within a fixed beam, and a limiting groove is welded and fixed within the adjusting beam, with both ends of the limiting groove sliding within the two limiting rods respectively;

[0013] The movement of the adjusting beam is guided by the sliding of the limiting groove within the two limiting rods, and the two limiting rods can limit the movement range of the limiting groove, which can effectively prevent the adjusting beam from detaching from the fixed beam.

[0014] Optionally, each of the positioning components includes a first groove formed in the adjusting beam, two locking blocks are slidably arranged in the first groove, and a locking spring is provided between the two locking blocks. The two ends of the locking spring abut against the adjacent ends of the two locking blocks through spring seats. Multiple locking slots are evenly formed in the fixing beam, and the two locking blocks are respectively locked into the corresponding two locking slots.

[0015] The two locking blocks are moved in opposite directions by the elasticity of the locking spring, and the two locking blocks are locked in the corresponding two locking slots to fix the positions of the fixed beam and the adjusting beam.

[0016] Optionally, a semi-circular block is fixed to each of the two card blocks at their far ends;

[0017] The semicircular block can be more accurately inserted into the slot when the two blocks move outward.

[0018] Optionally, each of the drive components includes a turntable that rotates within a first groove. Two sliding columns are fixed to the side end of the turntable. An adjustment groove is provided at the end of each of the two locking blocks near the turntable. The two sliding columns slide within the two adjustment grooves respectively. A connecting rod rotates within the adjustment beam. The turntable is fixed to the side end of the connecting rod.

[0019] The mechanism involves rotating the turntable by turning the connecting rod. As the turntable rotates, it causes the two sliding columns to move in a circular motion. During this circular motion, the two sliding columns slide within two adjustment slots, driving the two locking blocks to move relative to each other in a direction that brings them closer together. This causes the two locking blocks to leave the two slots, making it easier to move the adjustment beam.

[0020] Optionally, a handle is fixed to the side end of each of the two connecting rods.

[0021] In this application, the movement of the adjusting beam is guided by the sliding of the limiting groove within the two limiting rods, and the two limiting rods can limit the movement range of the limiting groove, which can effectively prevent the adjusting beam from leaving the fixed beam.

[0022] The elasticity of the snap-fit ​​spring pushes the two snap-fit ​​blocks to move in opposite directions, and the two snap-fit ​​blocks are snapped and fixed in the corresponding two slots, thereby fixing the position of the fixed beam and the adjusting beam.

[0023] By turning the connecting rod, the turntable is driven to rotate. When the turntable rotates, it drives the two sliding columns to make circular motion. When the two sliding columns make circular motion, they slide in the two adjustment slots respectively, driving the two locking blocks to move relative to each other in the same direction, so that the two locking blocks leave the two locking slots, making it easier to move the adjustment beam.

[0024] In this utility model, the adjustable aluminum alloy profile roof frame achieves stepless adjustment within a range of ±200mm of the roof span through the precise cooperation of the slot 6 with the limiting rod 4 at a spacing of 20mm, with an adjustment accuracy of ±1mm.

[0025] In this utility model, the adjustable aluminum alloy profile roof frame, with its combination design of double limiting rods and limiting grooves, limits the sway angle of the adjusting beam to ≤0.5°, improving stability by 40% compared to the traditional single-guide structure.

[0026] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] 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.

[0035] 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.

[0036] 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.

[0037] Example 1

[0038] Please see Figures 1-5 As shown, this embodiment provides an adjustable aluminum alloy profile ceiling frame, which is welded together from two longitudinal beams 1 and multiple transverse beams 2. Specifically, the top ends of the two longitudinal beams 1 are welded perpendicularly to the transverse beams 2 to form a rectangular frame structure for supporting the ceiling covering material. The longitudinal beams 1 adopt a modular design, including an extension beam 101, a fixed beam 102, and an adjusting beam 103, wherein one end of the adjusting beam 103 is welded and fixed inside the extension beam 101, and the other end is slidably embedded in the fixed beam 102, thereby realizing the telescopic adjustment of the longitudinal beams 1.

[0039] The guiding assembly consists of two parallel limiting rods 4 formed within the fixed beam 102 and a limiting groove 5 welded within the adjusting beam 103. Both ends of the limiting groove 5 are embedded in the sliding tracks of the two limiting rods 4, forming a double-track guiding structure. When the adjusting beam 103 slides axially along the fixed beam 102, the limiting groove 5 maintains linear motion under the constraint of the limiting rods 4, effectively preventing the adjusting beam 103 from swaying or dislodging. The length of the limiting rods 4 is designed to be 1.2 times the maximum stroke of the adjusting beam 103, ensuring that the limiting groove 5 remains within the effective guiding range during adjustment.

[0040] The positioning assembly includes a first groove 9 within the adjusting beam 103, two locking blocks 8 slidably disposed within the first groove 9, a locking spring 10 connecting the two locking blocks 8, and multiple slots 6 evenly distributed within the fixing beam 102. The locking spring 10 abuts against the opposite end faces of the two locking blocks 8 via spring seats, providing elastic thrust to expand the locking blocks 8 outwards. When the adjusting beam 103 slides to the target position, the semi-circular blocks at the ends of the locking blocks 8 automatically engage with the corresponding slots 6, forming a mechanical self-locking mechanism. The spacing of the slots 6 is designed to be 20mm to meet the accuracy requirements for ceiling span adjustment.

[0041] The drive assembly consists of a turntable 13 rotatably mounted within the first groove 9, two sliding columns 12 fixed to the side of the turntable 13, an adjustment groove 11 formed at the end of the locking block 8, and a connecting rod 7 penetrating the adjustment beam 103. The sliding columns 12 are embedded in the inclined track of the adjustment groove 11. When the connecting rod 7 is rotated by the handle 3, the turntable 13 drives the sliding columns 12 to perform a circular motion. The sliding columns 12 slide within the adjustment groove 11, forcing the two locking blocks 8 to retract inwards, causing the locking blocks 8 to disengage from the locking groove 6 and releasing the positioning lock. A single unlocking operation takes ≤15 seconds, meeting the requirements for rapid adjustment.

[0042] Example 2

[0043] Improvements based on Example 1: See Appendix Figure 1 An adjustable aluminum alloy profile ceiling frame is described, wherein the diameter of the semi-circular block fixed at the end of the locking block 8 is 90% of the width of the locking slot 6. Its curved surface design guides the locking block 8 to automatically align with the locking slot 6 during the sliding process of the adjusting beam 103, reducing installation difficulty. The surface of the semi-circular block is hardened to a hardness of HRC58-62, improving wear resistance by 3 times compared to a planar structure.

[0044] The handle 3 fixed at the end of the connecting rod 7 has a hexagonal cross-section with a diameter of 25mm and an anti-slip knurled surface. Testing shows that the single-handed operating torque can reach 15 N·m, meeting the driving torque required for unlocking while preventing slippage.
