【Embodiment】
The following example is being explained further and supplementing to the present invention, and the present invention is not limited in any way.
The tension bolt component of the present invention includes tensioner component 1, handle 2 and spring leaf 3.The tensioner component 1 and handle 2
It is flexibly connected, the handle 2 is fixedly connected with spring leaf 3, spring leaf 3 is connected into handle 2 can carry out the shape of drop in beam, institute
State fit precision and self-locking effect that tensioner component 1 can be used for regulation tension bolt component and body to be coordinated.The master of the present invention
Be characterized by, the tensioner component 1 can be adjusted by self-locking nut 12 and the cam 211 of the end of handle 2 its assembly precision and
Self-locking effect.
Specifically, the tensioner component 1 includes bearing pin 11, self-locking nut 12, extruded sleeve 13, stop collar 14 and limited block
15.The bearing pin 11 is cylindrical, and its one end end is threaded portion, and it is provided with external screw thread, for being threadedly coupled self-locking nut 12.
The other end end of the bearing pin 11 is provided with pin-and-hole, and it is used to be flexibly connected the handle 2.The self-locking nut 12 is threadedly coupled
In the threaded portion of the bearing pin 11, it can screw the fit precision for unscrewing and adjusting tensioner component 1.The extruded sleeve 13 and spacing
Set 14 is sheathed on the bearing pin 11 at intervals, i.e., provided with a stop collar 14 between each two extruded sleeve 13.The present embodiment
In, three extruded sleeves 13 and two stop collars 14 are provided with the bearing pin 11.The extruded sleeve 13 and stop collar 14 are in opening
Annular shape, its be open by one end of extruded sleeve 13 and stop collar 14 insertion vertically to the other end.Due to the presence of the opening,
So that stop collar 14 and extruded sleeve 13 have certain elasticity, radial dimension is adjustable.14 liang of the extruded sleeve 13 and stop collar
The outer wall difference at end is tapered, and its form fit, i.e. stop collar 14 are parallel with the conical outer wall of extruded sleeve 13, work as stop collar
14 and extruded sleeve 13 when being squeezed, the extruded sleeve 13 extrudes stop collar 14 vertically so that stop collar 14 deforms and edge
The conical outer wall for extruded sleeve 13 is moved out, so that its outside dimension becomes big and can be interference fitted with matrix, it is tight to reach
Leakproof fit purpose.The limited block 15 is sheathed on the bearing pin 11, its cam 211 for being used to abut handle 2 and extrude limit
Position set 14 and extruded sleeve 13, are allowed to deform and further finely tune the fit precision and self-locking property of tensioner component 1 and matrix.
As shown in figure 1, the handle 2 includes the connecting portion 21 that can be flexibly connected with bearing pin 11 and fixed with spring leaf 3 to connect
The drop in beam portion 22 connect.The connecting portion 21 is made up of two cams 211 separately.It is spaced between described two cams 211
Distance and the size of the end of bearing pin 11 match, and it causes the bearing pin 11 to be inserted between two cams 211.Institute
State and pin-and-hole is respectively equipped with cam 211, the pin-and-hole is axially vertical with the bearing pin 11.When bearing pin 11 load cam 211 it
Between when, on the pin-and-hole of the bearing pin 11 is corresponding with the pin-and-hole of the connecting portion 21 of handle 2, straight pin 4 is loaded in it and is caused
Bearing pin 11 is movably connected with handle 2.The drop in beam portion 22 is integrally formed with the connecting portion 21.In the present embodiment, institute
State drop in beam portion 22 L-shaped.The spring leaf 3 is L-shaped, and it is U-shaped by rivet with the drop in beam portion 22.In the bullet
The end of reed 3 is provided with screw hole.
Thereby, the tension bolt component of the present invention is just formd.During assembling, handle 2 and bearing pin 11 are first passed through into straight pin 4
It is movably connected.Then limited block 15, stop collar 14 and extruded sleeve 13 are sequentially inserted on bearing pin 11 successively.In use,
In the screw that tensioner component 1 is loaded to part matrix to be connected, self-locking nut 12 then is screwed into the threaded portion of the end of bearing pin 11, profit
Make part to be connected extruding stop collar 14 and extruded sleeve 13 with self-locking nut 12 so that stop collar 14 deform and along extruded sleeve 13
Conical outer wall outside move so that tensioner part to be connected, whole tension bolt component is connected to one by tensioner component 1 and matrix
Rise.When needing further to finely tune the fit precision between tensioner component 1 and matrix, the rotatable handle 2 makes the end of handle 2
The cam 211 in portion extrudes the limited block 15, and stop collar 14 and extruded sleeve 13 are extruded by limited block 15, so as to be allowed to deform and enter
The fit precision and self-locking property of one step section tensioner component 1 and matrix.
Although being disclosed by above example to the present invention, the scope of the present invention is not limited thereto,
Under conditions of present inventive concept, each component of the above can with art personnel understand similar or equivalent element come
