Between be fixedly connected with the tortuous seat 7 of clamping, limit and be provided with fastening strip hole 41 at the centre of surface line of journey clamping plate 4, clamp tortuous seat 7
In fastening strip hole 41, the two sidewalls in fastening strip hole 41 are equipped with length scale；By distinguishing sole both ends in use process
It is fixedly clamped in two limit journey clamping plates 4, then drives telescopic cylinder 5 mobile, telescopic cylinder 5 passes through during moving up
First power complications bar 61 pushes the bottom end of the second power complications bar 62 to rotate outward around the first hinge hole 34, while second is dynamic
The top of power complications bar 62 rotates inward movement around the first hinge hole 34, and the top of two the second power complications bars 62 pushes away simultaneously
Dynamic two clamp tortuous seat 7 and move inward along the fastening strip hole 41 on limit 4 surface of journey clamping plate, clamp tortuous seat 7 at this time in third
It is moved under the limit pulling function of power complications bar 63 along fastening strip hole 41, so that sole both ends are clamping tortuous seat 7
Under fixed function, sole center meander, the tortuous seats 7 of two clampings are always to making sole center in the case where drawing close together
Bending increases, while determining two clampings by the length scale of 41 side wall of fastening strip hole in clamping 7 moving process of tortuous seat
The mobile distance of tortuous seat 7, and then determine by mobile distance the bending stroke of sole, it is controlled after reaching specific complications stroke
5 power output end of telescopic cylinder processed is shunk, tortuous by the first power when the power output end retracted downward of telescopic cylinder 5 is mobile
Bar 61 pulls the bottom end of the second power complications bar 62 to rotate inward movement around the first hinge hole 34, and then drives the second power bent
The top of pole 62 rotates outward movement around the first hinge hole 34, drives the tortuous seat 7 of two clampings by the second tortuous bar 62
It is separated along fastening strip hole 4 to two sides, until sole is in normal condition, realizes the primary complications of sole, and so on, it is only necessary to
The multiplicating complications of sole can be realized by adjusting telescopic cylinder 5；It is not only small in size easy to carry, and only need to be by stretching
Sole complications can be realized in the flexible of contracting cylinder 5, and tortuous frequency is high, so that experimental efficiency is high；
As shown in Fig. 5, Fig. 6 and Fig. 7, clamping tortuous seat 7 includes that hinged block 71 and integrally connected are fixed on the top of hinged block 71
The platform 72 that is fixedly clamped in portion, the side wall of hinged block 71 are set there are two third hinge hole 711, and 62 one end of the second power complications bar connects
The third articulated shaft 631 of 63 one end of the first articulated shaft 621 and third power complications bar be respectively articulated with and be fixed on two thirds hinge
It connects in hole 711, the side wall for the platform 72 that is fixedly clamped is provided with bar shaped glove hole 73, and the upper bottom surface and bottom surface of bar shaped glove hole 73 are opposite
Fastening strip hole 74 there are two opening, integrally connected is fixed with the first fixed column 75 to the both ends side wall in two fastening strip holes 74 respectively, the
Positioning pressure spring 76 is mounted in one fixed column 75, one end of positioning pressure spring 76, which is fixedly connected with, clamps baffle 77, clamps baffle
Positioning sliding block 771 is integrally fixedly connected at 77 top and bottom face center, two positioning sliding blocks 771 slide clamping respectively
In two fastening strip holes 74, the side wall of positioning sliding block 771 is integrally fixedly connected with the second fixed column 772, positions pressure spring 76
One end be fixed in the second fixed column 772, by compression clamp baffle 77, clamp 77 both ends of baffle positioning sliding block 771 exist
Moved in fastening strip hole 74, while by 771 compression set pressure spring 76 of positioning sliding block, clamped until two between baffles 77 away from
From then one end two sides of sole capable of being fixedly clamped between two clamping baffles 77, prevent shoes with the width of sole one end
Bottom causes sole mobile to two sides in complications, influences tortuous precision；
It is fixedly clamped at the centre of surface of platform 72 and is provided with screw thread extruded hole 721, be connected through a screw thread in screw thread extruded hole 721
It is fixed with extruding screw 78, one end integrally connected of extruding screw 78 is fixed with crushing block 781, is placed in fastening strip at sole both ends
After in hole 74, rotary squeezing screw rod 78 realizes that extruding screw 78 moves down by threaded function, until crushing block 781 is by sole
One end be fixed, the fixation of baffle 77 is clamped by the fixation of crushing block 781 and both ends at this time, so that sole will not be more
Secondary complications process is mobile, and when causing repeatedly complications, tortuous position changes, and then influences the result of tortuous measurement.
The specifically used process of the device of resistance to bending and unbending test are as follows:
The first step clamps baffle 77 by compression, and the positioning sliding block 771 for clamping 77 both ends of baffle moves in fastening strip hole 74
It is dynamic, while by 771 compression set pressure spring 76 of positioning sliding block, until the distance between two clamping baffles 77 can be with sole one end
Width, then one end two sides of sole are fixedly clamped between two clamping baffles 77；
Second step, rotary squeezing screw rod 78 realizes that extruding screw 78 moves down by threaded function, until crushing block 781
One end of sole is fixed, clamps the fixation of baffle 77 by the fixation of crushing block 781 and both ends at this time；
Third step, driving telescopic cylinder 5 is mobile, and telescopic cylinder 5 passes through the first power complications bar 61 during moving up
The bottom end of the second power complications bar 62 is pushed to rotate outward around the first hinge hole 34, while the top of the second power complications bar 62
Movement is rotated inward around the first hinge hole 34, the top of two the second power complications bars 62 pushes the tortuous seat of two clampings simultaneously
7 move inward along the fastening strip hole 41 on limit 4 surface of journey clamping plate, clamp tortuous seat 7 at this time in the limit of third power complications bar 63
It is moved under the pulling function of position along fastening strip hole 41, so that sole both ends are under the fixed function for clamping tortuous seat 7, in sole
Portion's meander, the tortuous seats 7 of two clampings are pressing from both sides always to increasing sole center bending in the case where drawing close together
Determine that two clamp the mobile distance of tortuous seat 7 by the length scale of 41 side wall of fastening strip hole in tight complications 7 moving process of seat,
And then the bending stroke of sole is determined by mobile distance, control 5 power of telescopic cylinder is defeated after reaching specific tortuous stroke
Outlet is shunk, and pulls the second power by the first power complications bar 61 when the power output end retracted downward of telescopic cylinder 5 is mobile
The bottom end of tortuous bar 62 rotates inward movement around the first hinge hole 34, and then the top of the second power complications bar 62 is driven to surround
First hinge hole 34 rotates outward movement, drives two clamping complications seats 7 along fastening strip hole 4 to two sides by the second tortuous bar 62
Separation realizes the primary complications of sole until sole is in normal condition；
4th step, and so on, it is only necessary to the multiplicating complications of sole can be realized by adjusting telescopic cylinder 5, so
The cracking degree for observing sole complications position afterwards judges the resistance to tortuous of sole.
