Problems solved by technology

[0005] However, this patent still needs to be improved in actual use. At the same time, the design idea is to design from the installation tool, which will inevitably lead to a more complicated overall device and inconvenient operation.

Embodiment

[0031] like figure 1 As shown, a split nested self-fixing unilateral bolt fastener is used for unilaterally fixing the connecting plate 1, including bolt 2, split gasket 3, special sleeve 4, special gasket 5, nut 6 and the fixed sleeve 7, the middle section of the screw rod of the bolt 2 is in the shape of a hexagonal prism, the shape of the inner ring of the special gasket 5 matches the hexagonal prism, and is hexagonal, and the other parts of the bolt 2 are no different from ordinary bolts. The friction coefficient of the contact surface between the special gasket 5 and the connecting plate 1 is higher than that of the contact surface between the special gasket 5 and the nut 6 , and can be processed by heat treatment and machining.

[0032] During installation, the torque of the electric wrench is applied to the nut 6, and the friction torque generated by the thread pair between the nut and the bolt forces the nut to drive the bolt to rotate and slip. The contact friction b...

Abstract

The invention relates to a split nested self-fixing unilateral bolt fastener. The split nested self-fixing unilateral bolt fastener is used for unilaterally fixing a connection plate piece (1) and comprises a bolt (2), a split gasket (3), a nut (6) and a special gasket (5); the middle section of a threaded rod of the bolt (2) is in a prismatic shape; the inner circle shape of the special gasket (5) is matched with the prismatic shape of the middle section of the threaded rod of the bolt (2); and the friction coefficient between the special gasket (5) and the nut (6) is larger than the friction coefficient between the special gasket (5) and the connection plate piece (1). During installing, the nut (6) is rotated to get close to the connection plate piece (1), when the special gasket (5) is pressed on the connection plate piece (1) by the nut (6), static friction force is produced between the special gasket (5) and the connection plate piece (1), and the special gasket (5) is prevented from rotating, so that the bolt (2) is prevented from rotating along with the nut (6). Compared with the prior art, the split nested self-fixing unilateral bolt fastener has the advantages of being simple in structure, low in cost and the like.

Description

technical field [0001] The invention relates to a bolt fastener that can be used for unilateral installation in the connection and fastening of structural parts, in particular to a split nested self-fixing unilateral bolt fastener, which belongs to civil engineering and mechanical assembly technology field. Background technique [0002] At present, in the field of civil engineering and mechanical installation, there is a large demand for the installation of connection and fastening of structural parts. As far as bolts are commonly used at present, when performing connection and fastening operations on components, staff need to work on both sides of the components at the same time, and there is still no good implementation method for unilateral installation. This connection and fastening method has simple structure, convenient operation and good load bearing, but it is only suitable for open cross-section components. In some special occasions, such as connecting and fastenin...
