Sleeve anchor，as an important fastener, it plays a crucial role in fields such as construction engineering and mechanical equipment installation. Its structure and working principle reflect the ingenuity and practicality of the design. The following is the official language description of its structure and working principle:

Structural Description of Sleeve Anchor  

The sleeve anchor is mainly composed of the following key components:

Bolt: The bolt is the core component of the sleeve anchor, with a threaded outer end used to receive nuts and transmit fastening force. The head or special part of the bolt is designed with a special shape (such as cone, wedge, etc.) to push the sleeve to expand during installation.

Sleeve: A sleeve is a metal component wrapped around a bolt, typically made of high-strength materials to ensure sufficient strength and stability during expansion. The internal design of the casing has a structure that matches the bolt head or special part, so that radial expansion can occur when pushed by the bolt.

Nut: The thread of the nut and bolt matches, generating downward pressure through rotation, pushing the bolt head or special part downward, thereby causing the sleeve to expand in the hole.

In addition, depending on specific requirements, sleeve anchors may also include auxiliary components such as washers, spring washers, etc. to improve fastening effectiveness and prevent loosening.

The Working Principle of Sleeve Anchor  

The working principle of sleeve anchor is based on the principle of physical expansion, and the specific process is as follows:

Preparation stage: Firstly, drill holes of appropriate depth and diameter on the substrate (such as concrete, stone, brick wall, etc.), and clean the debris inside the holes.

Installation phase: Insert the sleeve part of the sleeve anchor  into the hole, then thread the bolt through the reserved hole of the object to be fixed (such as steel structural components, mechanical equipment, etc.) and insert it into the sleeve. Finally, install the nut on the outer end of the bolt.

Tightening stage: Use a wrench or other tools to gradually tighten the nut. As the nut is tightened, the head or special part of the bolt will move downward and push the sleeve to expand inside the hole. The expansion process of the casing generates radial expansion force, which forms a tight contact and firm fixation between the casing and the hole wall.

Completion stage: When the nut reaches the specified tightening torque, the sleeve anchor is installed. At this point, the fixed object forms a stable connection between the sleeve anchor and the substrate.

In summary, sleeve anchor achieves stable fixation in the substrate through its unique structure and working principle, providing reliable support and connection for various structural objects.
