Description

Technical Field

[0001] The utility model belongs to the technical field of anchor bolt fasteners, and more specifically relates to a detachable anchor bolt. Background Art

[0002] In the field of construction engineering and equipment installation, anchor bolts are a commonly used fixing connector, widely used in base materials such as concrete and masonry to fix structural components, equipment and devices. Traditional anchor bolts are mostly non-detachable and difficult to remove or replace once installed, which not only increases the difficulty of construction but also affects maintenance efficiency. In situations where temporary fixation is required, the design of traditional anchor bolts lacks flexibility; therefore, in order to meet the needs of reusable and high-strength fixation, the research and development of detachable anchor bolts has gradually become a research hotspot.

[0003] Although the current detachable anchor bolt designs can achieve a certain degree of disassembly and reuse, most of them have complex structures, many parts and high assembly costs. At the same time, special tools are required for operation, which affects convenience. Especially in harsh construction environments, users usually need an anchor bolt structure that can be easily installed, quickly disassembled, and has sufficient strength and stability.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: in the solution of the present invention, the coordination of the main rod, spring piece, main rod head, main rod core and other components enables the various parts of the anchor bolt to work together during installation and removal, ensuring firmness and stability; this structure enables the anchor bolt to be not only quickly installed on the substrate, but also conveniently removed through simple operations;

[0014] The first and second buttons are respectively set on the main rod core and the upper end of the main rod. Users only need to press or rotate the buttons to install and remove the anchor bolt. No additional tools are required, and the operation is convenient. It is especially suitable for frequent changes or adjustments, which greatly improves work efficiency.

[0015] The main rod core can slide in the main rod channel, and the rebound force provided by the compression spring causes the main rod core to automatically reset, making it easy to disassemble and reset; this structure reduces the resistance to installation or disassembly, making the anchor operation smoother;

[0016] The upper end of the spring clip is designed in an I-shaped design and is embedded in the I-shaped groove formed by the fixing grooves on both sides of the limit ring and the grooves of the rod body, ensuring a reliable connection between the spring clip and the main rod. This structure increases the pull-out resistance when subjected to tension, making the anchor bolt more stable and more resistant to vibration when subjected to external forces, effectively preventing loosening.

[0017] The anchor bolts in this solution are reusable. Compared with disposable anchor bolts, detachable anchor bolts can be reused and are suitable for occasions that require regular maintenance or temporary installation. They cause little damage to the base material, and the detachable design reduces damage to the base material, making them suitable for installation requirements where the structure cannot be damaged.
