Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: a kind of blind rivet sealing structure based on knife handle, including turn
Son 1, pulling claw component 2 and knife handle component 3, pulling claw component 2 are mounted in the centre bore of rotor 1, and knife handle component 3 is mounted on pulling claw group
The bottom end of part 2.
Pulling claw component 2 includes pull rod 201, pull rod connecting rod 202, pulling claw seat 203, fixing sleeve 204 and pulling claw 205, pulling claw
Seat 203 is plugged in the centre bore of rotor 1, and pulling claw seat 203 is hexagon head structure on the outer wall of bottom end, facilitates pulling claw seat
203 installation and removal, and the end face of hexagonal offsets with 302 end face of blind rivet, and is slightly larger than 302 end face of blind rivet, it is ensured that Song Daoshi
302 end face of blind rivet smoothly loose knife can be arrived to, while not influencing the function of pulling claw 205, pull rod connecting rod 202 is threaded in pulling claw
The top of seat 203, pull rod 201 is threaded in the top of pull rod connecting rod 202, between pulling claw connecting rod 202 and pulling claw seat 203
It is socketed with self-locking gasket 8, self-locking gasket 8 can at elevated pressures, and energy self-locking pulling claw seat 203 prevents pulling claw seat 203 from pine occurs
Dynamic, fixing sleeve 204 is threaded at the waist mouth of pulling claw seat 203, and fixing sleeve is step structure, lug boss position and pulling claw 205
Groove match, prevent 205 swing offset of pulling claw, influence the original dynamic balancing of main shaft, pulling claw 205 is arranged in fixing sleeve 204
Bottom end, and pulling claw 205 and the outer wall of pulling claw seat 203 are connected together, and the bottom end of pulling claw 205 is provided with guide groove 4, guide groove 4
It is provided with the inside of 1 centre bore of rotor.
Knife handle component 3 includes knife handle 301 and blind rivet 302 with blind rivet, and the knife handle 301 with blind rivet is entrenched in 1 bottom end of rotor
The indent conical surface on, the blind rivet 302 is threaded at the cone mouth on 301 top of knife handle with blind rivet, the top of blind rivet 302
Leakage-proof socket 6 is offered, the bottom end fitting connection of leakage-proof socket 6 and pulling claw seat 203, the inside of leakage-proof socket 6 offers seal groove 7, close
Sealing groove 7 is disc-shaped structure, and the presence of leakage-proof socket 6 to dock between blind rivet 302 and pulling claw seat 203 more stable and close
Sealing groove 7, which exists, improves air-tightness, and steam is avoided to enter the inside of pulling claw, it is ensured that the reliability of central water outlet function, and draw
Nail 302 is connected together with pulling claw 205, offers importing on the slide-and-guide end face of guide groove 4, blind rivet 302 and pulling claw seat 203
Angle 5 can be convenient and smoothly slide between pulling claw 205 and lead-in angle 5, facilitates pulling claw, smoothly imports, make between 203 and blind rivet 302
Folder knife and loose knife process it is more smooth, greatly reduce seamless socket on the outer wall of the frictionally damage pulling claw seat 203 of part
There is sealing ring 1, sealing ring 1 plays sealing function, while mitigating the friction of 203 outer wall of pulling claw seat Yu 1 centre bore of rotor, also
