Description

Technical Field

[0001] This utility model belongs to the field of metal joint technology, specifically relating to a rotatable metal joint angle adjustment mechanism. Background Technology

[0002] Metal joints for modular frames are key components used to connect the various members or components of the frame, achieving stable structural assembly and functional expansion through reliable mechanical connections. Their design must balance strength, flexibility, durability, and ease of installation, and they are widely used in construction, industrial equipment, warehouse racking, exhibition displays, and other fields.

[0003] Currently, over 70% of the metal connectors used in modular scaffolding on the market adopt a one-piece molded structure with either a two-way (two-way connection) or a three-way (three-way connection). While this standardized design meets basic connection requirements, it reveals significant limitations when facing complex spatial layouts. Because the angles of the one-piece connectors are fixed (e.g., a two-way connector only supports a 180° straight connection, and a three-way connector defaults to a 90° right angle), the included angles of the members cannot be dynamically adjusted during assembly. This results in insufficient adaptability of modular scaffolding for irregularly shaped structures, curved surfaces, or non-orthogonal connection scenarios. Utility Model Content

[0004] The purpose of this utility model is to provide a rotatable metal joint angle adjustment mechanism, which aims to solve the problem that in the above-mentioned metal joints in the prior art, the angle of the integral structure joint is fixed (e.g., double-connectors only support 180° straight-line connection, and three-connectors default to 90° right angle), and the angle of the rods cannot be dynamically adjusted during assembly, resulting in insufficient adaptability of the assembly frame in the construction of irregular structures, curved surfaces, or non-orthogonal connection scenarios.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rotatable metal joint angle adjustment mechanism, comprising a first metal joint and a threaded mounting hole formed on the surface of the first metal joint, a connecting seat connected to the outer side wall of the first metal joint, a mating seat connected to the other end of the connecting seat, and a second metal joint connected to the other side of the mating seat.

[0006] A rotating block is connected to one end of the docking seat near the connecting seat. A rotating groove is provided on the inner wall of the connecting seat. A locking bolt is connected through the surface of the connecting seat.

[0007] As a preferred embodiment of the rotatable metal joint angle adjustment mechanism of this utility model, the rotating block has a T-shaped cross-section, and the rotating block and the rotating groove on the inner wall of the connecting seat constitute a rotating structure.

[0008] In a preferred embodiment of the rotatable metal joint angle adjustment mechanism of this utility model, the locking abutment bolt is threadedly connected to the connecting seat, and the locking abutment bolt passes through the connecting seat and abuts against the rotating block.

[0009] As a preferred embodiment of the rotatable metal joint angle adjustment mechanism of this utility model, a reinforcing block is connected to the opening of the inner wall of the connecting seat, a reinforcing shaft is connected to one side of the reinforcing block, and a linkage block is connected to the other end of the reinforcing shaft.

[0010] In a preferred embodiment of the rotatable metal joint angle adjustment mechanism of this utility model, the linkage block is installed on the inner wall of the opening of the docking seat, and the reinforcing block, the reinforcing shaft and the linkage block are all made of stainless steel.

[0011] As a preferred embodiment of the rotatable metal joint angle adjustment mechanism of this utility model, one end of the reinforcing shaft near the reinforcing block is connected to an insert block, an assembly spring is connected to the surface opening of the insert block, and an assembly buckle is connected to the other end of the assembly spring. The assembly buckle and the inner wall of the opening of the reinforcing block form a fitting structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention connects the first and second metal connectors to the lever end of the splicing frame, and then rotates the rotating block at one end of the docking seat at the opening end of the connecting seat, thereby driving the first and second metal connectors to adjust their angles. After adjusting to the required angle of the assembly frame, four locking bolts are passed through the connecting seat and threadedly engaged with the rotating block, thus facilitating the stability of the assembled frame and improving the practicality of the metal connectors.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides the following technical solution: a rotatable metal joint angle adjustment mechanism, including a first metal joint 1 and a threaded mounting hole 2 opened on the surface of the first metal joint 1, a connecting seat 3 connected to the outer side wall of the first metal joint 1, a mating seat 4 connected to the other end of the connecting seat 3, and a second metal joint 5 connected to the other side of the mating seat 4.

[0023] A rotating block 6 is connected to one end of the docking seat 4 near the connecting seat 3. A rotating groove 7 is provided on the inner wall of the connecting seat 3. A locking bolt 8 is connected through the surface of the connecting seat 3.

[0024] Preferably, the rotating block 6 has a T-shaped cross-section, and the rotating block 6 and the rotating groove 7 on the inner wall of the connecting seat 3 form a rotating structure.

[0025] In practical use, the rotating block 6 is rotated along the rotating groove 7 on the inner wall of the connecting seat 3, thereby driving the metal connector to adjust the angle.

[0026] Preferably, the locking bolt 8 is threadedly connected to the connecting seat 3, and the locking bolt 8 passes through the connecting seat 3 and abuts against the rotating block 6.

[0027] In practical use, by passing the locking bolt 8 through the connecting seat 3 and abutting against the rotating block 6, the metal joint after the angle is adjusted can be kept stable, thus making it easy to adapt to splicing frames with different installation angles.

[0028] Preferably, a reinforcing block 9 is connected to the opening on the inner wall of the connecting seat 3, a reinforcing shaft 10 is connected to one side of the reinforcing block 9, and a linkage block 11 is connected to the other end of the reinforcing shaft 10.

[0029] Preferably, the linkage block 11 is installed on the inner wall of the opening of the docking seat 4, and the reinforcing block 9, the reinforcing shaft 10 and the linkage block 11 are all made of stainless steel.

[0030] In practical use, the use of reinforcing block 9, reinforcing shaft 10 and linkage block 11 facilitates the reinforcement of connecting seat 3 and docking seat 4, thereby improving the service life of the metal joint angle adjustment mechanism.

[0031] Preferably, the reinforcing shaft 10 is connected to an insert 12 at one end near the reinforcing block 9, an assembly spring 13 is connected to the opening on the surface of the insert 12, and an assembly buckle 14 is connected to the other end of the assembly spring 13. The assembly buckle 14 and the inner wall of the opening of the reinforcing block 9 form a fitting structure.

[0032] In practical use, during the process of connecting the insert block 12 with the reinforcing block 9, the assembly buckle 14 is driven to compress the assembly spring 13 to deform. At the same time, it is convenient to drive the assembly buckle 14 to fit into the opening of the inner wall of the reinforcing block 9, thereby facilitating the assembly of the reinforcing block 9, the reinforcing shaft 10 and the linkage block 11 into a whole, which improves the rigidity of the metal joint angle adjustment mechanism.

[0033] The working principle of this utility model is as follows: The first metal connector 1 and the second metal connector 5 are connected to the lever end of the splicing frame. Then, the rotating block 6 at one end of the docking seat 4 is rotated in the rotating groove 7 of the connecting seat 3, thereby driving the first metal connector 1 and the second metal connector 5 to adjust their angles. After adjusting to the required angle of the assembly frame, the four locking bolts 8 are threaded through the connecting seat 3 and abut against the rotating block 6, thus facilitating the stability of the assembled frame and allowing for 360° angle adjustment, improving the practicality of the metal connectors. Furthermore, by connecting the reinforcing shaft 10 at one end of the linkage block 11 to the reinforcing block 9, the insertion block 12 at one end of the reinforcing shaft 10 is driven to engage with the opening on one side of the reinforcing block 9. At this time, the assembly buckle 14 is driven to compress the assembly spring 13, and then the assembly buckle 14 is engaged into the opening on the inner wall of the reinforcing block 9. This facilitates the assembly of the reinforcing block 9, the reinforcing shaft 10 and the linkage block 11 into a single structure, thereby facilitating the reinforcement of the connecting seat 3 and the docking seat 4, preventing deformation and breakage at the connection, and improving the hardness of the metal joint angle adjustment mechanism.
