Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bolts, in particular to a T-shaped bolt assembly with a pre-buried groove to prevent it from falling off. Background Art
[0002] Embedded channels are widely used in many fields. During construction, they are prefabricated in concrete, and T-bolts play an extremely critical role in them. When installing electromechanical equipment, the head of the T-bolt is embedded in the embedded channel, and its rod can pass through the mounting hole of the electromechanical equipment. The nut and the T-bolt cooperate to generate a strong clamping force, firmly fixing the electromechanical equipment on the embedded channel, ensuring that the electromechanical equipment remains stable, safe and not easily displaced during use.
[0003] Existing structures often simply rotate the T-bolt. The operator rotates it with appropriate force and angle based on experience and the actual groove design. During the rotation process, the operator feels the contact and fit between the bolt and the inner curved edge of the groove. When the bolt is rotated to a certain angle, the T-shaped head will be firmly hung on the inner curved edge of the embedded groove.
[0004] However, the vibration generated during the operation of the equipment reduces the friction between the nut and the bolt, causing the nut to loosen. The T-bolt is very likely to rotate in the opposite direction as the nut loosens. In this way, the T-bolt will gradually move away from its original position, eventually leading to a falling-off accident. Utility Model Content
