It moves to after being contacted with 25 inner upper wall of limit chamber, lifting tube 22 can not continue up, when lifting tube 22 moves downwardly to
After contacting with the lower wall inside limit chamber 25, lifting tube 22 can not continue to move downward, and both improve the up and down motion of lifting tube 22
Stability in the process, and the range of lifting tube 22 is limited.
It is damaged caused by upper side of the upper side wall inside fixing sleeve 1 nut 6 in order to prevent, further, fixing sleeve 1
Inner sidewall on be fixed with protective pad 4, the middle part of protective pad 4 offers the through-hole 5 passed through for the screw rod end of fastening bolt 7,
Through-hole 5 is aligned with the hole heart in stud exit hole 3, upper inside 6 upper side of nut and fixing sleeve 1 by the way that protective pad 4 to be arranged in
Between side wall, the rigid contact of nut 6 Yu fixing sleeve 1 is effectively avoided.
In order to increase nut 6 and install the contact area of plate surface, installation plate surface is prevented to be worn, and avoid nut
6 directly contact with mounting plate, further include the first gasket 9 further, the upside of the first gasket 9 and the downside of nut 6 connect
Touching, the downside of the first gasket 9 and the upside face contact of mounting plate, and the first gasket 9 is located in fixing sleeve 1, the first gasket 9 it is interior
Circle is located at the periphery of the bolt hole of mounting plate, and the screw rod end of fastening bolt 7 passes through the first gasket 9 and is spirally connected with nut 6, when fastening,
On the periphery for the bolt hole that first gasket 9 is fixed on mounting plate, and by the bolt hole of the Kong Xinyu mounting plate of the first gasket 9
The alignment of the hole heart.
It further include centering ring 10 further, centering ring 10 is set in the first gasket 9 for the ease of the fixation of fixing sleeve 1
Outer ring on, the outer ring of centering ring is contacted with fixing sleeve 1, the downside face contact of the upper side of centering ring and nut 6, centering ring
Centering ring is set on the outer ring of the first gasket 9 by the upside face contact of downside and mounting plate before set 1 is welded and fixed, and
It is fixed on the upper side of mounting plate, while being aligned the hole heart of the hole heart of centering ring and the bolt hole of mounting plate, convenient for fixing sleeve 1
Positioning is welded and fixed set 1, set 1 is welded and fixed when fixed, not by being embedded nut 6 in fixing sleeve 1 after positioning
Welded nut 6, heated deformed threads influence fastening bolt 7 is tightened when nut 6 being avoided to weld, and guarantees 6 intensity of nut, and combine
First gasket 9 and protective pad 4 make nut 6 prevent nut 6 from damaging while can not moving up and down, and make spiral shell by limiting slot 8
Mother 6 can not rotate, and realize the fixation to nut 6.
In order to increase the contact area of fastening bolt 7 Yu substrate surface, substrate surface is prevented to be worn, further, also
