Embodiment
Below in conjunction with the accompanying drawings and the utility model is further described embodiment：
Term " first ", " second " be only used for describe purpose, and it is not intended that instruction or imply relative importance or
The implicit quantity for indicating indicated technical characteristic.Thus, " first " is defined, the feature of " second " can be expressed or imply
Ground includes one or more this feature.
As shown in Fig. 1, Fig. 4 to Fig. 7, a kind of special sunk head rivet of pre-buried channel flow, including for being connected with pre-buried channel flow 2
Sunk head rivet 1, sunk head rivet 1 include rivet cap 11 and rivet bar 12, and rivet cap 11 and rivet bar 12 are coaxially connected, rivet bar 12
Including the first rivet bar 121, the second rivet bar 122 and the 3rd rivet bar 123, the first rivet bar 121 and the 3rd rivet bar 123 are logical
The second rivet bar 122 is crossed to connect, the first rivet bar 121 is connected with rivet cap 11, the first rivet bar 121, the second rivet bar 122,
3rd rivet bar 123 and rivet cap 11 are integrally formed, and the second rivet bar 122 is in round platform, the first rivet bar 121 and the 3rd rivet bar
123 be in cylinder.
The operation principle so set：When sunk head rivet 1 and pre-buried channel flow 2 rivet, due to the rivet hole of pre-buried channel flow 2
Diameter is constant, can be with pre-buried channel flow 2 in the second rivet bar 122 of round platform when applying a downward pressure to sunk head rivet 1
Rivet hole produce extruding, when more firmly be pressed downward sunk head rivet 1, the second rivet bar contacted with the rivet hole of pre-buried channel flow 2
122 diameter of section becomes big, and the rivet hole of the second rivet bar 122 and pre-buried channel flow 2 rivets closer, due to pre-buried channel flow 2
Rivet hole can continue to increase bigger with the diameter of section that the second rivet bar 122 contacts so that sunk head rivet 1 can be held
The pressure received increases bigger；Due to the rivet hole of the second rivet bar 122 and pre-buried channel flow 2 rivet it is unusual close, so as to
So that with the rivet hole of pre-buried channel flow 2 rivet close sunk head rivet 1 be not easy it is backing out from the rivet hole of pre-buried channel flow 2.
The beneficial effect so set is that sunk head rivet 1 provided by the utility model is in the first rivet in cylinder
