Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the utility model includes screw rod 1 and the fixing nut installed successively from bottom to up along screw rod 1
10th, sealing ring 9, the first washer 8, lower chock plug 7, breathing chuck 6, upper chock plug 5, second packing ring 4 and traveling nut 2.Fixing nut
10th, sealing ring 9, the first washer 8, lower chock plug 7, breathing chuck 6, upper chock plug 5, second packing ring 4 are sequentially overlapped, close to connect.The
One washer 8 is between lower chock plug 7 and sealing ring 9 so that and lower chock plug 7 is not contacted directly with sealing ring 9, play protection sealing
The effect of circle 9 does not stay gap again.Second packing ring 4 avoids traveling nut 2 from rotating between traveling nut 2 and upper chock plug 5
Upper chock plug 5 is worn in journey, contact area is reduced, the application of pressure is influenced, so as to influence sealing effect.
Fixing nut 10 is fixedly connected with screw rod 1, and as support portion, support is sequentially overlapped each accessory on it.
Sealing ring 9, the first washer 8, lower chock plug 7, breathing chuck 6, upper chock plug 5, the centre of second packing ring 4 are equipped with through hole,
Screw rod 1 is sealed through sealing ring 9, the first washer 8, lower chock plug 7, breathing chuck 6, upper chock plug 5, the through hole of second packing ring 4
The 9, first washer 8 of circle, lower chock plug 7, breathing chuck 6, upper chock plug 5, second packing ring 4 can move freely on screw rod 1, replacement side
Just, and alternatively it is applicable in the nozzle without specification.
The outside welding rotation handle 3 of traveling nut 2, traveling nut 2 are threadedly coupled with screw rod 1.Rotation handle 3 is rotated,
Traveling nut 2 is moved along 1 screw thread of screw rod.The main function of traveling nut 2 is pressed to upper chock plug 5, it is promoted to press down, and
Breathing chuck 6 and sealing ring 9 is made to be stretched toward both sides.
As shown in Fig. 2, the top half of the latter half of upper chock plug 5 and lower chock plug 7 is pyramidal structure, it is taper respectively
Structure 50 and pyramidal structure 70, the upper port 60 and lower port 62 of breathing chuck 6, which are respectively equipped with, disposes the taper of pyramidal structure recessed
Mouthful.The side wall of the pyramidal structure of upper chock plug 5 and lower chock plug 7 and the angle β of vertical direction are more than the madial wall of conical depression with erecting
Nogata to angle α.Such size design applies pressure to breathing chuck 6 convenient for upper chock plug 5, easily generates extruding force, and generates
The contact surface of extruding force is big, and breathing chuck 6 is promoted to be stretched toward both sides.
The outer wall of breathing chuck 6 is equipped with annular groove 61.After breathing chuck 6 comes into full contact with inside pipe wall, annular groove 61
Gap is left with inside pipe wall, after the extruding force that breathing chuck 6 receives releases, breathing chuck 6 can easily divide with inside pipe wall
From avoiding breathing chuck 6 and inside pipe wall and completely attach to, form the state of vacuum, be not easy to separate.
Sealing ring 9 at least there are two, successively side by side installation.Sealing ring 9 is used as sealed source, and sealing element is more, sealing effect
Better.
The outer diameter of the upper surface of upper chock plug 5 is more than the outer diameter of sealing ring 9.The outer diameter of sealing ring 9 matches with nozzle diameter,
The outer diameter and the diameter more than nozzle of so upper 5 upper surface of chock plug, therefore on applying pressure to during chock plug 5, upper chock plug 5 is not
Nozzle can be fully sunk in, and can be come into full contact with traveling nut 10, upper chock plug 5 is brought pressure to bear on convenient for traveling nut 10.
