Description

Technical Field

[0001] This utility model relates to the field of anchoring device technology, and more specifically, to a rotating head anchoring tool. Background Technology

[0002] In port operations, it is often necessary to set connection points in structures such as gates and walls for tying and fixing, to enhance wind resistance and prevent movement or structural damage. Expansion bolts are often used for anchoring in the current work process. However, during use, expansion bolts still have the following problems: 1. For hollow structures such as hollow bricks, the expansion position cannot make contact, resulting in poor anchoring effect; 2. The expansion part is thin and is greatly affected by rust, which can easily lead to loosening; 3. When connecting with other structures after anchoring, it is still necessary to connect additional threaded heads and other adapters, resulting in poor integration. Utility Model Content

[0005] As a further preferred embodiment of this utility model, the thread of the threaded rod extends from one end to one end of the pin hole, and the thread extends between the bottom of the pin hole and the bottom of the notch.

[0006] By extending the thread setting, and using washers and reinforcing nuts, the range of the thickness of the hollow brick is increased, and the thread setting improves the anchoring effect of the threaded rod after expansion at the notch.

[0007] As a further preferred embodiment of this utility model, the rotating expansion plate is two stainless steel plates that are bonded together.

[0010] By using guide grooves and guide arc surfaces, the sliding ring moves towards the bottom of the notch under guidance, reducing the offset of the rotating expansion plate.

[0011] As a further preferred embodiment of the present invention, the bottom end of the notch is provided with a triangular apex with the tip pointing towards the rotating expansion plate, and each of the rotating expansion plates is provided with a force-receiving groove on the side away from the counterweight head. The force-receiving grooves on both sides are arranged opposite to each other, and a triangular groove is formed at the joint. The tip of the apex points towards the joint of the force-receiving grooves on both sides.

[0012] By adjusting the apex angle and force groove settings, the expansion effect of the rotating expansion plate is improved, thereby enhancing the expansion effect near the bottom of the notch in the threaded rod.

[0015] As a further preferred embodiment of this utility model, the fixing pin includes a smooth hexagon socket bolt and a corresponding nut, the head of the hexagon socket bolt is rotatably connected to the pin hole on one side, and the nut is fixed inside the pin hole on the other side.

[0016] The technical effects and advantages of this utility model are as follows: 1. The rotating head anchoring tool of this utility model uses a rotating expansion plate to horizontally engage the hollow structure, and locks the rotating expansion plate with a washer and a reinforcing nut to achieve anchoring of the hollow structure, thereby improving the versatility of this anchoring tool.

[0017] 2. When anchoring a solid wall, this utility model uses the notch in the threaded rod to divide the expansion, which increases the thickness and strength of the deformed part, enhances stability, improves the stability of the anchoring tool, and increases safety and structural lifespan.

[0018] 3. The connection after anchoring is achieved by setting the threaded rod, which improves the integrity of the structure. The transition can be completed without the need for additional structures, reducing the workload during anchoring.
