Embodiment
Embodiment is described in detail a kind of mechanical fixed tensioning device be made up of three pieces of drifts further below.
Embodiment 1
As Fig. 1, shown in 2, a kind of mechanical fixed tensioning device be made up of three pieces of drifts, comprise drift 1, middle drift 2, lower drift 3, slide block 8, the outer side surface of described upper drift 1 and lower drift 3 is respectively equipped with projection, the inner side surface up and down of described slide block 8 is arranged with groove, the inner side surface up and down that the projection that described upper drift 1 and lower drift 3 are respectively equipped with is arranged in slide block 8 is arranged with groove, described middle drift 2 is located between drift 1 and lower drift 3, and middle drift 2 slides along the inclined-plane of upper drift 1 and lower drift 3, one end of described middle drift 2 is provided with bolt 12, this bolt 12 is connected with the adjusting nut 6 that slide block 8 the other end is provided with through slide block 8.When needing to install, as shown in Figure 1, when body 5 is lifted on base 10, put into plate 9, now leave gap between base 10 and link 4, dextrorotation adjusting nut 6, then it is with slide block 8 for base, by bolt 12, the small end of middle drift 2 is pulled to the large end of upper drift 1 and lower drift 3, the total height of three drifts is increased, like this, through the transmission of link 4 and plate 9, just by body 5(equipment) compress and be fixed on base 10.
Need dismounting time, left-handed adjusting nut 6, still with slide block 8 for base, by bolt 12, the small end of middle drift 2 is pushed to the small end of upper drift 1 and lower drift 3, at this moment three drifts total height reduce, link 4 just unclamps, and withdraws plate 9, and body 5 just can hang away.Realize displacement 0-3mm small on perpendicular direction to compensate.
Embodiment 2
On the basis of embodiment 1, be also provided with the baffle plate 7 be enclosed within bolt 12 between slide block 8 described as shown in Figure 1, 2 and adjusting nut 6, this baffle plate 7 is fixedly connected with slide block 8, and is stuck in the annular slot that adjusting nut 6 is provided with; Be fixedly connected or tensioning time link 4 and the first dress gap of body 5 be 1-3mm, at this moment rotating adjusting nut 6 makes middle drift 2 along bolt 12 axis to, upper drift 1, under drift, the large end of 3 moves about 10-30mm, three pieces of drift total heights increase 1-3mm, just gap can be eliminated, impose certain resiliently deformable additional force more simultaneously, just complete body 5 being fixedly connected on base.During dismounting body 5, adjusting nut 6 rotates backward, then it limits by baffle plate 7, still with slide block 8 for base, by bolt 12, the small end of middle drift 2 upwards drift 1, lower drift 3 is pushed 10-30mm, at this moment three pieces of drift total heights reduce 1-3mm, namely occur the gap of 1-3mm between link 4 and body 5, pump plate 9, just body 5 can be hung oneself away from base 10.
Embodiment 3
On the basis of embodiment 1, described upper drift 1 and lower drift 3 are same vertical trapezium drifts, and the inclined-plane of the upper drift 1 of this vertical trapezium and lower drift 3 is oppositely arranged, described projection is located on the major part of drift 1 and lower drift 3, and described middle drift 2 is isosceles trapezoid drifts.Upper drift 1 and lower drift 3 adopt vertical trapezium drift, and middle drift 2 adopts isosceles trapezoid drift, and 3 drifts are more stable when relative movement, and pressure-bearing surface is plane simultaneously, safer during installation.
Embodiment 4
In above-described embodiment 1, the gradient of described upper drift 1, middle drift 2 and lower drift 3 is less than 1:10.The substantially horizontal of middle drift 2 and the stressed ratio of Vertical direction are 1:10, and consider frictional loss, its effective ratio is 1:(7-8.5), if middle drift 2 is with the bolt of M24, then it is equivalent to M60 bolt and makes a concerted effort to the direct handle of body 5.
In addition, adjust pad 11 thickness that is positioned on base 10, i.e. the size of preset clearance between adjustable link 4 and body (5).
Embodiment 5
In in the arbitrary enforcement of embodiment 1-5, described upper drift 1, middle drift 2 and lower drift 3 are respectively equipped with through hole, and upper drift 1, middle drift 2 and lower drift 3 are cuboid after superposing, upper drift 1, middle drift 2 are communicated with the through hole on lower drift 3; Upper drift 1, middle drift 2 and lower drift 3 are respectively equipped with through hole coordinate with link 4, in the process used, the lower end of link 4 is free to extend in the through hole that drift 1, middle drift 2 and lower drift 3 are respectively equipped with, and can not have influence on the installation between body 5 and base 10.
In sum, the utility model provides a kind of mechanical fixed tensioning device be made up of three pieces of drifts, tensioning body and base is fixed according to adjusting nut in the process of practicality, both sides are avoided to beat, only in the space that side is less, the screw thread that use diameter is less and power just can realize the connection that large-diameter thread just can be born.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection domain of the present utility model with the same or analogous design of the utility model.
