Detailed Description
The following detailed description of embodiments, structures, features and effects of the torque adjustable lock bolt assembly according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 to 8, the utility model discloses a locking bolt subassembly with adjustable moment, including the outer nail body 1, the interior nail body 2, top 4, wherein: the internal nail body 2 is arranged in a mounting hole 7 on the external nail body 1, the internal nail body 2 is sleeved with a torque ring 3, the torque ring 3 is arranged in a mounting cavity 6 arranged at the front part of the external nail body 1, the rod part of the internal nail body 2 is connected with the inner ring of the torque ring 3 through stripes 9, the tail part of the internal nail body 2 is provided with a tip 4, the outer conical surface of the tip 4 is attached to the inner conical surface of a locking pin 5, the locking pin 5 is movably arranged in a pin hole 8 arranged on the external nail body 1, and the outer side surface of the external nail body 1 is provided with threads. Two locking pins 5 are arranged to form a tapered cavity with variable size together, and the top of the tip 4 is arranged in the tapered cavity. The inner nail body 2 is connected with the outer nail body 1 through threads. The inner circle of the moment ring 3 can be oval, square, hexagonal and the like. The torque ring 3 is installed in the installation cavity 6 of the outer nail body 1 through the matching of a square clamping block arranged outside.
When the bolt assembly is used, referring to fig. 9 to 10, a proper torque ring 3 is selected according to requirements, the head of the inner nail body 2 is pulled and screwed by a wrench or an electric tool to drive the inner nail body 2 to rotate, the torque ring 3 is driven by the inner nail body 2 to rotate, and the torque ring 3 drives the outer nail body 1 to rotate so that the bolt assembly is screwed into the mounting position or the nut. When the moment limited by the bolt assembly is achieved during installation, the moment maximum value of the moment ring 3 is achieved by the inner nail body 2, the inner nail body 2 and the moment ring 3 begin to slip, the moment ring 3 cannot be driven to continue rotating by the inner nail body 2, and the installation moment of the outer nail body 1 is achieved. The inner nail body 2 is continuously rotated, the inner nail body 2 and the outer nail body 1 start to rotate relatively, the inner nail body 2 is screwed into the outer nail body 1 along the threads, the inner nail body 2 extrudes the tip 4 to move forwards, the outer conical surface of the tip 4 extrudes the inner conical surface of the locking pin 5, the locking pin 5 moves towards two sides, and the locking effect of the assembly and the mounting hole or the nut is achieved. And continuing to rotate the inner nail body 2 until the head wrenching position is damaged, so that the height of the head is reduced, and finishing the installation.
