Specific embodiment
Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in Figure 1 and Figure 2, tension seat 8 of the invention be one end fix, the c-type jaw structure of another end opening.It tenses
The fixing end of seat 8 is horizontally disposed turnbuckle 9, spiral shell in the external screw thread of turnbuckle 9 and the horizontal screw hole of fixing end of tension seat 8
Line is meshed.The open end for tensing seat 8 is vertically arranged hold-down bolt 7, external screw thread and tension 8 open end of seat of hold-down bolt 7
Vertical screw hole internal screw thread is meshed.The end setting pressing plate 6 and liner 10 of hold-down bolt 7, pressing plate 6 are preferably metal plate, liner
10 are coated on the bottom surface of pressing plate 6, and hold-down bolt 7, liner 10 and pressing plate 6 are symmetricly set on the open end for tensing seat 8 or more two sides.
As shown in figure 4, mobile tension control mechanism is set close to fixing end tensing 8 opening inner side of seat, mobile tension control mechanism
Sleeve 12 is open at one end towards turnbuckle 9, and other end closing sets gradually elastic element from closed end in sleeve 12 outward
13, thrust bearing 14 and circlip for hole 15, position of the circlip 15 in sleeve 12 is fixed, for limiting elastic element
13 and position of the thrust bearing 14 in sleeve, prevent elastic element 13 and thrust bearing 14 from leaving sleeve 12.Elastic element 13
The internal diameter of outer diameter and sleeve 12 match, the outer diameter of thrust bearing 14 is slightly less than the internal diameter of sleeve 12, and elastic element 13 can be with
It is cylindroid helical-coil compression spring or disk spring.It is wide on the inside of the jaw of the overall diameter of sleeve 12 and the tension seat 8 under locking state
Degree matching, the closed end of sleeve 12 offsets with 5 lateral surface of metal frame when locking, the thrust bearing 14 and turnbuckle 9 of open end
End offset.As shown in figure 3, in the aperture 16 for the surface setting racetrack for tensing seat 8, the length direction of aperture 16 and tension
The tension direction of bolt 9 is consistent, and positioning pin 11 is vertically arranged in aperture 16, and the end of positioning pin 11 is located at the closing of sleeve 12
In end, positioning pin 11 can only be moved along direction is tensed, and due to the limitation of positioning pin 11, sleeve 12 is also only axially free
Degree, cannot do the rotation of circumferencial direction.
When the invention works, as shown in Figure 1, by center framework net 2, protection lining net 3, top surface and bottom surface are filtered for two layers up and down
Totally five layers of net are superimposed veil 4, are fitted into metal frame 5, using rivet 1 first by five layers net be fixed on metal frame 5 on one side
In, as shown in Figure 1 and Figure 2, several pressing plates 6 for being coated with liner 10,10 patch of liner are placed in upper and lower two sides on its opposite one side
Nearly veil is caught in several tension seats 8 on each pressing plate 6.As shown in Fig. 2, the position of the corresponding pressing plate 6 of hold-down bolt 7, tenses seat
8 sleeve 12 resists metal frame 5, and upper-lower compacting bolt 7 is gradually tightened but do not tightened completely first, adjusts the institute on each side
There is hold-down bolt 7, turnbuckle 9 is rotated after all tightening and starts to adjust tightness.When turnbuckle 9 screws in, due to nibbling for screw thread
Conjunction, which makes to tense outside seat 8, to move, and hold-down bolt 7 is driven to move with outside pressing plate 6, so that the filtering veil 4 that pressing plate 6 clamps is opened outward
Tightly.The end of turnbuckle 9 is against on thrust bearing 14, and when turnbuckle 9 rotates, turnbuckle is can be absorbed in thrust bearing 14
9 rotary force, only transferring axial thrust, prevents the rotation of elastic element 13 in sleeve 12, since the diameter of thrust bearing 14 omits
Less than the internal diameter of sleeve 12, therefore it can prevent sleeve 12 from turnbuckle 9 being followed to rotate simultaneously.The section of sleeve 12 is compared to tension
The end area of bolt 9 is bigger, therefore the forced area acted on metal frame 5 is bigger, and pressure is small, prevents the outer of metal frame 5
See extrusion damage.The effect of thrust produced by 9 precession of turnbuckle is so that the compression of elastic element 13 generates deformation, one side elasticity
Element 13 can provide thrust more flexible, prevent rigid power drawing crack flexibility wire side；On the other hand due to elastic force and deformation
Distance avoids the force of different operation personnel's hand at the ratio of determination so as to each degrees of tensions for tensing seat 8 of quantitative control
Degrees of tensions unevenness problem caused by difference.As shown in Figure 3, Figure 4, during sleeve 12 is mobile, positioning pin 11 is in aperture
It is moved in 16, positioning pin 11 can limit sleeve 12 and turnbuckle 9 is followed to rotate, and equally playing with thrust bearing 14 prevents sleeve
The effect of 12 rotations.In adjustment, pays attention to successively adjusting the tightness of each tension seat 8, when tension can suitably unclamp some drawing
Tight seat 8, when turnbuckle 9 rotates, can be readily observed positioning since aperture 16 is located at the surface of tension seat 8
The moving distance of pin 11 learns that the tension displacement of turnbuckle 9 avoids to quantitatively control each degrees of tensions for tensing seat 8
Degrees of tensions unevenness problem caused by the difference of the force of different operation personnel's hand, and the limit due to there is positioning pin 11, also not
Tightening force excessive the defects of leading to drawing crack wire side can occur, final installation obtains the high quality filtering veil 4 of even stretch tension, has
Effect extends the service life of filtering veil 4.Remaining each side for filtering veil 4 is finally fixed on metal using bolt or rivet 1
