[embodiment]
The following example is to further explanation of the present invention and supplements, and does not constitute any limitation the present invention.
Tension bolt assembly of the present invention comprises tensioner assembly 1, handle 2 and spring sheet 3.Described tensioner assembly 1 is flexibly connected with handle 2, described handle 2 is fixedly connected with spring sheet 3, spring sheet 3 and handle 2 connect into the shape can carrying out drop in beam, and described tensioner assembly 1 can be used for regulating quality of fit and the self-locking effect of tension bolt assembly and body to be coordinated.Broad outlines of the present invention is, described tensioner assembly 1 regulates its assembly precision and self-locking effect by the cam 211 of self-locking nut 12 and handle 2 end.
Particularly, described tensioner assembly 1 comprises bearing pin 11, self-locking nut 12, extruded sleeve 13, stop collar 14 and limiting stopper 15.Described bearing pin 11 is in cylindric, and its end, one end is screw section, and it is provided with outside thread, for the self-locking nut 12 that is threaded.The other end end of described bearing pin 11 is provided with pin-and-hole, and it is for being flexibly connected described handle 2.Described self-locking nut 12 is threadedly connected to the screw section of described bearing pin 11, and it can screw and unscrews and regulate the quality of fit of tensioner assembly 1.Described extruded sleeve 13 and stop collar 14 are sheathed on described bearing pin 11 at intervals, are namely provided with a stop collar 14 between every two extruded sleeves 13.In the present embodiment, described bearing pin 11 is provided with three extruded sleeves 13 and two stop collars 14.Described extruded sleeve 13 and stop collar 14 are the circular of opening, and its opening is through to the other end vertically by one end of extruded sleeve 13 and stop collar 14.Due to the existence of this opening, thus make that stop collar 14 and extruded sleeve 13 have certain elasticity, radial dimension is adjustable.The outer wall at described extruded sleeve 13 and stop collar 14 two ends is tapered respectively, and its form fit, namely the conical outer wall of stop collar 14 and extruded sleeve 13 parallels, when stop collar 14 and extruded sleeve 13 are squeezed, described extruded sleeve 13 extrudes stop collar 14 vertically, stop collar 14 is deformed and conical outer wall along extruded sleeve 13 outwards moves, thus make its outside dimension become large and can with matrix interference fit, to reach close-fitting object.Described limiting stopper 15 is sheathed on described bearing pin 11, and it extrudes stop collar 14 and extruded sleeve 13 for abutting the cam 211 of handle 2, makes it to deform and finely tunes quality of fit and the self-locking property of tensioner assembly 1 and matrix further.
As shown in Figure 1, described handle 2 comprises the joint 21 that can be flexibly connected with bearing pin 11 and the drop in beam portion 22 be fixedly connected with spring sheet 3.Described joint 21 is made up of two cams 211 separately.Between described two cams 211, the distance at interval and the size of described bearing pin 11 end match, and it makes described bearing pin 11 can be inserted between two cams 211.Described cam 211 is respectively equipped with pin-and-hole, and described pin-and-hole is axial vertical with described bearing pin 11.When bearing pin 11 loads between cam 211, on the pin-and-hole of described bearing pin 11 is corresponding with the pin-and-hole of described handle 2 joint 21, loads straight pin 4 within it and bearing pin 11 and handle 2 are movably connected.Described drop in beam portion 22 is one-body molded with described joint 21.In the present embodiment, described drop in beam portion 22 is in L-type.Described spring sheet 3 is in L-type, and itself and described drop in beam portion 22 pass through rivet and U-shaped.Screw hole is provided with at the end of described spring sheet 3.
By this, tension bolt assembly of the present invention is just defined.During assembling, first handle 2 and bearing pin 11 are movably connected by straight pin 4.Then limiting stopper 15, stop collar 14 and extruded sleeve 13 are inserted on bearing pin 11 successively according to the order of sequence.During use, tensioner assembly 1 is loaded in the screw of to be connected matrix, then self-locking nut 12 is screwed in the screw section of bearing pin 11 end, self-locking nut 12 is utilized to make to be connected to extrude stop collar 14 and extruded sleeve 13, stop collar 14 is made to deform and move outside the conical outer wall of extruded sleeve 13, thus to be connected of tensioner, whole tension bolt assembly is linked together by tensioner assembly 1 and matrix.When needing the quality of fit further between fine setting tensioner assembly 1 and matrix, rotatable described handle 2, the cam 211 of handle 2 end is made to extrude described limiting stopper 15, extrude stop collar 14 and extruded sleeve 13 by limiting stopper 15, thus make it to be out of shape and regulate quality of fit and the self-locking property of tensioner assembly 1 and matrix further.
Although by above embodiment to invention has been announcement, scope of the present invention is not limited thereto, and under the condition not departing from the present invention's design, above each component can be replaced with the similar or equivalent element that art personnel understand.
