Below in conjunction with accompanying drawing, the utility model is described in further detail.But conduct is not to any restriction foundation of the present utility model.The purpose of this utility model is to provide a kind of wall-hanging dynamic adjustments bearing pin connection part.This connection part solved install waste time and energy, a series of mechanical connection problems such as secondary damage, outward appearance are not beautiful, cannot regulate, unfavorable maintenance, uncontrollable moment, overcome the deficiency that prior art exists.
As shown in Figure 1, a kind of wall-hanging dynamic adjustments bearing pin connection part, comprises wall built-up nut 1, carrying bearing pin 2, spring 3, adjusting screw 4 and outer gear screw 5.
As shown in Figure 2, wall built-up nut 1 comprises counterbore 6, supporting plate face 7, fitted shaft 8 and internal thread 9.Counterbore 6 can be fixed on wall with sunk head rivet or sunk screw; Wall built-up nut 1 as required shape can meet arbitrarily the shape of installation requirement for dihedral 10, in-line 11, circle 12, star 13 etc., as shown in Fig. 3,4,5,6.Fitted shaft 8 is used in conjunction with the carrying endoporus 19 of carrying bearing pin 2; Internal thread 9 meshes with the outside thread 22 of adjusting screw 4, when needs self-locking, at the middle part of fitted shaft 8, closes up.
As shown in Figure 7, carrying bearing pin 2 comprises bearing pins outer surface 14, boot segment 15, internal thread 16, adjustment hole 17, interior block 18 and bearing holes 19.The surface of bearing pins 14 can meet for fluting, annular knurl etc. the arbitrary shape of installation requirement; Boot segment 15 can be chamfering, fillet or changeover portion; Internal thread 16 matches with outer gear screw 5; Adjustment hole 17 matches with spring 3, adjusting screw 4; Interior block 18 should block spring 3 but can allow adjusting screw 4 freely pass through.According to the thickness of composite material element to be installed, select the carrying bearing pin 2 of different length, the adjusting screw 4 of only need back-outing can be changed carrying bearing pin 2 at any time.
As shown in Figure 8, spring 3 comprises the peaceful section 21 of spring body 20, and spring 3 is positioned at the adjustment hole 17 of carrying bearing pin 2.
As shown in Figure 9, adjusting screw 4 comprises outside thread 22, bar portion 23, head 24 and twisting hole 25.Twisting hole 25 can meet for interior hexagon, cross flute profile, straight groove shape etc. the arbitrary shape of twisting demand.
As shown in figure 10, outer gear screw 5 comprises outer gear surface 26, top 27 and bolt portion 28.Outer gear screw 5 can be manufactured by nonmetallic material, meets locking function and appearance requirement; Outer gear surface 26 can meet for plane, annular knurl etc. the arbitrary shape of installation requirements; Top 27 can be for meeting the arbitrary shape of installation requirements and appearance requirement; Bolt portion 28 is meshed with the internal thread 16 of carrying bearing pin 2.
Be concrete Placement of the present utility model as shown in figure 11, a kind of connecting means of wall-hanging dynamic adjustments bearing pin connection part, is first riveted to wall built-up nut 1 use sunk head rivet 29 on wall 30 by counterbore 6, inserts carrying bearing pin 2; Spring 3 is inserted in after adjusting screw 4, and the interior block 18 of laminating carrying bearing pin 2 is screwed into 9 li of the internal threads of wall built-up nut 1, puts into after fixed block 31,32, by spanner twisting adjusting screw 4, to desired location, is screwed into outer gear screw 5 fixing.
Due to special structure form of the present utility model, there is the function of dynamic adjustments.Its dynamic adjustments principle is: the bearing holes 19 of carrying bearing pin 2 is hole axle type light face Spielpassung with the fitted shaft 8 of wall built-up nut 1, can rotate freely and slide.When tightening outer gear screw 5, compress composite material and treat fixed block 31,32, its reaction force acts is in outer gear screw 5, outer gear screw 5 is threaded with carrying bearing pin 2, there is no relative movement, its reaction force be delivered to carrying bearing pin 2 on, make to carry bearing pin 2 by interior block 18 Compress Springs 3 stored energy, generation elastic force.Because adjusting screw 4 is to be threaded with wall built-up nut 1, that face contacts with spring 3, there is no relative movement, its elastic force is delivered to again on carrying bearing pin 2, also be delivered to the direct composite material that compresses on outer gear screw 5 and treat fixed block 31,32 simultaneously, it is finally for tightening outer gear screw 5 Compress Springs 3, thereby can control predetermined control moment by tightening the number of turns of outer gear screw 5, make composite material treat that fixed block 31,32 maintains relatively-stationary pressure, the function of dynamic adjustments that Here it is always.When composite material produces creep, vibrations distortion or when damaged, only need continue to tighten outer gear screw 5 can keep relatively-stationary pressure until fixed block 31,32 because of long-time use.Or use spanner to regulate adjusting screw 4, thereby also can change the decrement torque-controllable of spring 3.
Need to change while safeguarding, the outer gear screw 5 of only need back-outing, then by the spanner adjusting screw 4 of back-outing, extract carrying bearing pin 2; Insert again new carrying bearing pin 2, be screwed into adjusting screw 4, be screwed into outer gear screw 5.Its maintenance is quite convenient and swift.
The utility model is owing to having taked above technological scheme, and neither bulkhead matrix in damage, can obtain beautiful appearance requirement again, and capable of dynamic adjusting, and torque-controllable, can change at any time, and safety reliability is high, easy to maintenance.Therefore, the utility model is the best specialty screwed assembly of dynamic adjustments fastener areas.
