Embodiment
Name preferred embodiment, and become apparent from intactly illustrating the utility model with reference to accompanying drawing.
Embodiment 1
As shown in Figure 1, Figure 2 and Figure 3, M64 internal and external threads sleeve bolt connection component of the present utility model includes bolt
1st, threaded sleeve 2 and packing ring 3, bolt 1 include hexagon-head 11, polished rod portion 12 and the threaded portion 13 being sequentially connected, hexagon-head
11st, it is integrally formed between polished rod portion 12 and threaded portion 13, the side in the connection polished rod of hexagon-head 11 portion 12 is provided with scrobicular ring (in figure not
Show), elastic component 111 is embedded with inside scrobicular ring.Junction between hexagon-head 11 and polished rod portion 12 is provided with arc sections, circular arc
The radius in portion is 2mm, to strengthen the bonding strength between hexagon-head 11 and polished rod portion 12.
Outer surface of the inner surface of threaded sleeve 2 provided with internal thread 21, threaded sleeve 2 is provided with external screw thread 22, threaded sleeve
2 either end facet is provided with paired concave part 23, and concave part 23 passes through the axle center 24 of threaded sleeve 2.
The component fixes hexagon-head 11 and concave part 23, by bolt 1 and thread bush respectively in connection using instrument
Pipe 2 is counter-rotation, makes to be threadedly coupled between threaded portion 13 and internal thread 21, completes whole component connection.Wherein, elasticity is passed through
