Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to steel structure connectors with adjustable angles. Background Technology

[0002] In the construction and installation of steel structures, connectors play a crucial role. However, existing steel structure connectors are mostly one-piece molded or have fixed angles, lacking flexibility in application and unable to be adjusted according to actual on-site installation needs. This often necessitates secondary cutting or processing of the steel structure itself, or even custom-made special connectors, when encountering non-standard or complex angle connection situations. This not only increases additional labor time and costs but also affects the overall installation efficiency and adaptability of the structure. Therefore, there is an urgent need for a connector that can flexibly and stably achieve multi-angle adjustment to simplify the installation process and improve construction efficiency. To address this, we propose an adjustable-angle steel structure connector to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable angle steel structure connector.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable angle steel structure connector includes a fixed ring, on both sides of which sliding sleeves are symmetrically fitted, and a hinge arm is fixedly connected to the outer wall of the outer ring of the sliding sleeve. A hinge shaft is inserted inside the hinge arm, and the hinge shaft and the hinge arm are hingedly connected. The hinge arm is connected to the connector head through the hinge shaft, and a fixed sleeve is fixedly inserted at the center of the fixed ring.

[0005] Preferably, a partition block is fixedly inserted inside the fixed sleeve, and the partition block is located at the center of the fixed sleeve.

[0006] Preferably, the sliding assembly has a U-shaped groove inside, the cross-section of the fixing ring is a U-shaped structure, the fixing ring is inserted inside the sliding assembly, and the sliding assembly can slide along the surface of the fixing ring.

[0007] Preferably, the upper and lower ends of the fixed sleeve are symmetrically fixedly equipped with annular sleeves, the two sides of the annular sleeve are symmetrically fixedly equipped with guide arms, the upper and lower ends of the fixed sleeve are symmetrically equipped with telescopic arms, and the telescopic arms are symmetrically equipped with the annular sleeves. The two sides of the annular sleeve are symmetrically equipped with guide arms, and the two sides of the telescopic arms are symmetrically equipped with fixing blocks, and the fixing blocks and guide arms are connected by connecting pins.

[0008] Preferably, the guide arm has a groove on its surface, the connecting pin is inserted into the groove, and the connecting pin is slidably connected to the guide arm.

[0009] Preferably, a spring and a limiting block are sequentially fitted onto the surface of the connecting pin. The spring is located between the limiting block and the guide arm. The limiting block is fixed to the connecting pin. One end of the spring is fixed to the limiting block, and the other end of the spring is fixed to the guide arm.

[0010] Preferably, the connector and the telescopic arm have threaded holes symmetrically formed on their surfaces.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses an adjustment mechanism consisting of a sliding kit, a hinge arm, a hinge shaft, and a connector to enable the connector to rotate a wide range around the hinge shaft. This design breaks the limitation of fixed angles in traditional connectors, allowing construction workers to make quick and flexible adjustments according to the actual docking angle of the steel structure. This significantly improves the adaptability of the connector to different application scenarios and eliminates the trouble and cost of customizing connectors with special angles.

[0012] 2. By designing a sliding telescopic adjustment mechanism (such as pulling the telescopic arm to extend the distance between it and the annular sleeve), this utility model can adapt to steel structures of different pipe diameters and effectively increase the contact area with the steel structure. This feature makes the connector grip more firmly when fixed, greatly improving the stability and reliability of the connection. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 An adjustable angle steel structure connector includes a fixing ring 1, with sliding sleeves 2 symmetrically fitted on both sides of the fixing ring 1. A hinge arm 3 is fixedly connected to the outer wall of the sliding sleeve 2. The hinge arm 3 is movably connected to a connector 5 for fixing a steel pipe via a hinge shaft 4. A central fixing sleeve 6 for fitting onto the steel pipe is fixedly provided at the center of the fixing ring 1.

[0017] Furthermore, refer to Figure 2 It can be seen that the sliding kit 2 has a convex groove inside, and the cross-section of the fixing ring 1 is a matching convex structure. The sliding kit 2 can slide and be positioned along the surface of the fixing ring 1.

[0018] Furthermore, refer to Figure 2 It can be seen that the upper and lower ends of the fixed sleeve 6 are symmetrically fixed with annular sleeves 7, the two sides of the annular sleeve 7 are symmetrically fixed with guide arms 8, and the upper and lower ends of the central fixed sleeve 6 are also symmetrically provided with telescopic arms 11. The telescopic arms 11 are arranged opposite to the annular sleeve 7, and the telescopic arms 11 are slidably connected to the guide arms 8 through connecting pins 9.

[0019] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the surface of the guide arm 8 is provided with a long strip-shaped hole and groove, and the connecting pin 9 passes through the hole and groove, so that the telescopic arm 11 can move telescopically relative to the annular sleeve 7.

[0020] Furthermore, refer to Figure 4 It can be seen that a spring 12 and a limiting block 14 are sequentially fitted on the connecting pin 9. The limiting block 14 is fixedly connected to the connecting pin 9. The spring 12 is located between the limiting block 14 and the guide arm 8. One end of the spring 12 is fixedly connected to the limiting block 14, and the other end is fixedly connected to the telescopic arm 11.

[0021] Furthermore, refer to Figure 4 It can be seen that the surfaces of the connector 5 and the telescopic arm 11 are symmetrically provided with threaded holes for inserting bolts.

[0022] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the internal fixed sleeve 6 is fitted with a partition block 13.

[0023] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the center fixing sleeve 6 is placed in the predetermined position of the main steel pipe, and then the telescopic arm 11 is pulled outward. The telescopic arm 11 moves in the groove of the guide arm 8 through the connecting pin 9, thereby smoothly extending the distance between it and the annular sleeve 7, so that the connector can be securely fitted and clamped on the steel pipe. Finally, bolts are used to pass through the threaded holes on the surface of the connector 5 and the telescopic arm 11 for fastening, completing the initial installation of the main body.

[0024] Subsequently, when it is necessary to connect another steel pipe at a different angle, the construction personnel can manually rotate the hinge arm 3. Since the hinge arm 3 is hinged to the connector 5 through the hinge shaft 4, the connector 5 can rotate freely in the required plane. After adjusting the target angle, the auxiliary steel pipe to be connected can be directly inserted or fixed in the connector 5 to achieve a stable multi-angle connection. The whole process is seamless, easy to adjust, and reliable to fix. The above is the complete working principle of this utility model.
