Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile technology, and in particular to an improved corner fixing structure for aluminum alloy profiles. Background Technology

[0002] Aluminum alloy profiles are metal structural materials made by adding alloying elements such as copper, magnesium, and zinc to aluminum as a base, with a density of 2.7 g / cm³. 3 It also boasts a strength exceeding that of some alloy steels and exhibits excellent corrosion resistance. It is widely used in the aerospace industry, automotive lightweighting, rail transportation, photovoltaic frames, and building doors and windows, achieving weight reductions of over 50% compared to steel.

[0003] like Figure 4 As shown, this is the corner fixing structure used in the previous generation of aluminum alloy profile assembly fixing. Similar to most corner fixing blocks on the market, it requires pre-drilling holes at the connection points of the fixing corner block, crossbeam, and longitudinal beam. Then, tools are used to screw fasteners into the holes between the fixing corner block, crossbeam, and longitudinal beam to achieve the corner fixing operation between the crossbeam and longitudinal beam. However, this corner fixing structure has the following shortcomings in actual use: First, when fixing the corners of aluminum alloy profiles, operators need to carry tools and fasteners, which increases the workload and difficulty of fixing the corners of aluminum alloy profiles and reduces the convenience and efficiency of fixing the corners of aluminum alloy profiles. Second, with this fixing method, the fasteners are directly exposed to the external environment, and other personnel can use tools to disassemble or destroy the corner fixing structure, resulting in poor safety.

[0004] In view of this, it is particularly important to design and manufacture a corner fixing structure that can achieve tool-free and convenient assembly and fixing of aluminum alloy profiles, while avoiding the exposure of fasteners, for application in the assembly and fixing of aluminum alloy profiles. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the original corner fixing of aluminum profiles required the use of fasteners and tools, which increased the workload and difficulty of fixing the corners of aluminum profiles. At the same time, the fasteners were directly exposed to the external environment, which posed a certain degree of risk of disassembly and damage. Therefore, an improved corner fixing structure for aluminum alloy profiles is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An improved corner fixing structure for aluminum alloy profiles includes a hollow corner fixing block, a crossbeam located at the right end of the corner fixing block, and a longitudinal beam located at the upper end of the corner fixing block. The right and upper ends of the corner fixing block are both open. The right and upper ends of the corner fixing block are fixedly connected with positioning buckles that can be combined and inserted with the crossbeam and longitudinal beam. A locking mechanism is provided between the corner fixing block, the crossbeam, and the longitudinal beam for tool-free convenient combination and fixing of the crossbeam and longitudinal beam onto the corner fixing block.

[0007] As a further description of the above technical solution: The locking mechanism includes a C-shaped sliding buckle integrally fixed at the middle of both ends of the crossbeam and the longitudinal beam, two T-shaped locking parts movably installed on the C-shaped sliding buckle inside the crossbeam and the longitudinal beam, and an inner locking part disposed between the corner fixing block and the two T-shaped locking parts.

[0008] As a further description of the above technical solution: The inner locking part includes a 45° bend located at the lower left corner of the corner fixing block, a limiting block fixed inside the corner fixing block and abutting against two T-shaped lock pieces, an outer stud rotatably installed between the 45° bend and the limiting block, a sliding lock block installed between the outer stud and the corner fixing block through an inner threaded sleeve, a lock post symmetrically fixed on the sliding lock block and passing through the T-shaped lock pieces and the limiting block, and a lock hole opened on the T-shaped lock piece and matching the lock post.

[0009] As a further description of the above technical solution: The external stud is fitted with a folding knob at one end facing a 45° angle.

[0010] As a further description of the above technical solution: A detachable cover plate for the folding knob is installed between the corner fixing block and the 45° angled bend.

[0011] As a further description of the above technical solution: The limiting block is symmetrically provided with two limiting holes for accommodating the locking pin, and the limiting holes and the locking pin are in transition fit.

[0012] As a further description of the above technical solution: The front end of the corner fixing block is detachably fitted with a fixing cover plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, C-shaped sliding buckles and T-shaped locking components are installed at both ends of the crossbeam and longitudinal beam. A 45° angled bend, a limiting block, an outer stud, a sliding lock block, and an angled bend cover are also provided on the corner fixing block. The T-shaped locking component can be movably installed at the middle of both ends of the crossbeam or longitudinal beam via the C-shaped sliding buckle. Then, the crossbeam and longitudinal beam can be combined and fixed with the corner fixing block using positioning buckles. When the operator holds and rotates the folding knob on the outer stud, the sliding lock block can drive the two locking pins towards the T-shaped locking component under the helical transmission action between the outer stud and the inner threaded sleeve. When the two locking pins are inserted into the lock holes on the T-shaped locking component, the crossbeam and longitudinal beam can be simultaneously locked and fixed to the corner fixing block. This structure enables tool-free corner fixing between the crossbeam and longitudinal beam, effectively reducing the workload and difficulty of fixing aluminum profiles at the corner. Simultaneously, the operating part of the corner fixing block can be hidden and protected, thereby improving the safety of use after the corner fixing structure is fixed. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-4This utility model provides a technical solution: an improved corner fixing structure for aluminum alloy profiles, including a hollow corner fixing block 1, a crossbeam 2 set at the right end of the corner fixing block 1, and a longitudinal beam 3 set at the upper end of the corner fixing block 1. The right end and the upper end of the corner fixing block 1 are both open. The right end and the upper end of the corner fixing block 1 are fixedly connected with positioning buckles 104 that can be combined and inserted with the crossbeam 2 and the longitudinal beam 3. A locking mechanism is provided between the corner fixing block 1, the crossbeam 2 and the longitudinal beam 3 for tool-free convenient combination and fixing of the crossbeam 2 and the longitudinal beam 3 on the corner fixing block 1.

[0018] Specifically, such as Figure 1-3 As shown, the locking mechanism includes a C-shaped sliding buckle 6 integrally fixed at the middle of both ends of the crossbeam 2 and the longitudinal beam 3, two T-shaped locking pieces 7 movably installed on the C-shaped sliding buckle 6 inside the crossbeam 2 and the longitudinal beam 3, and an inner locking part disposed between the corner fixing block 1 and the two T-shaped locking pieces 7.

[0019] The inner locking part includes a 45° bend 101 located at the lower left corner of the corner fixing block 1, a limiting block 102 fixed inside the corner fixing block 1 and abutting against two T-shaped locking pieces 7, an outer stud 4 rotatably installed between the 45° bend 101 and the limiting block 102, a sliding lock block 5 installed between the outer stud 4 and the corner fixing block 1 via an inner threaded sleeve 502, a locking pin 501 symmetrically fixed on the sliding lock block 5 and passing through the T-shaped locking piece 7 and the limiting block 102, and a lock hole 701 on the T-shaped locking piece 7 that matches the locking pin 501. When the locking pin 501 on the sliding lock block 5 is inserted between the T-shaped locking piece 7 and the limiting block 102, the T-shaped locking piece 7 can be locked and fixed inside the corner fixing block 1, thereby indirectly fixing the crossbeam 2 and the longitudinal beam 3 together on the corner fixing block 1.

[0020] In addition, a folding knob 401 is rotatably installed on one end of the external stud 4 facing the 45° angled bend 101, which makes it convenient for operators to hold and rotate the external end of the external stud 4 for adjustment. At the same time, an angled bend cover plate 8 is detachably installed between the corner fixing block 1 and the 45° angled bend 101 to cover the folding knob 401. After the corner fixing block 1 is fixed, the external stud 4 and the folding knob 401 can be covered to prevent other personnel from maliciously operating this part and causing the corner fixing block 1 to unlock.

[0021] Specifically, such as Figure 1-3 As shown, two limiting holes 103 are symmetrically arranged on the limiting block 102 for accommodating the locking pin 501, and the limiting holes 103 and the locking pin 501 are in transition fit. The selection of this fit method can prevent the end of the locking pin 501 from being offset and stably inserted into the limiting block 102, thereby improving the locking effect of the locking pin 501 on the T-type lock 7.

[0022] Specifically, such as Figure 1-3As shown, a fixing cover plate 105 is detachably installed on the front end of the corner fixing block 1.

[0023] Working principle: When using the device, for corner fixing of the crossbeam 2 and longitudinal beam 3, the operator first takes two T-shaped locking pieces 7 and slides them into the C-shaped sliding buckles 6 at the designated positions on the crossbeam 2 and longitudinal beam 3. Second, the operator aligns one end of the T-shaped locking pieces 7 on the crossbeam 2 and longitudinal beam 3 and inserts it into the positioning buckle 104 of the corner fixing block 1. At this point, the two T-shaped locking pieces 7 can slide vertically into the corner fixing block 1 and abut against the limiting block 102. Third, the operator holds and rotates the folding knob 401 on the inner and outer studs 4 of the 45° angled turn 101. This drives the outer stud 4 to rotate. Under the helical transmission between the outer stud 4 and the inner threaded sleeve 502, the sliding block 5 can move at a 45° angle towards the T-shaped locking block 1. When the T-shaped lock 7 moves in the direction of the sliding block 5, the locking pin 501 on the sliding block 5 can be gradually inserted into the locking hole 701 of the T-shaped lock 7 and the limiting hole 103 on the limiting block 102. When the operator can no longer rotate the outer stud 4, it means that the sliding block 5 is abutting against the two T-shaped locks 7. At this time, the two T-shaped locks 7 can be locked and fixed between the limiting block 102, the sliding block 5 and the locking pin 501, thus completing the tool-free corner fixing operation between the crossbeam 2 and the longitudinal beam 3. Finally, rotate the folding knob 401 to adjust to the folded state, and then take out the inclined bend cover plate 8 and fasten the inclined bend cover plate 8 onto the 45° inclined bend 101. At this time, the inclined bend cover plate 8 can cover the outer stud 4 and the folding knob 401 to prevent direct contact operation in the future.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
