The fixture block 102 of spacing of both sections on the width Y of test specimen, two fixture blocks 102 separate from the both sides of test specimen 20 so that test specimen
20 are restricted between two fixture blocks 102, each fixture block 102 be provided with can along the thickness direction Z of test specimen make near or away from roller
101 movable blocks 103 for sliding.
In the present embodiment, the thickness direction Z of the length direction X of test specimen, the width Y of test specimen and test specimen constitutes three-dimensional
Coordinate system.
Each movable block 103 includes that test specimen 20 can be pressed on so that test specimen 20 is restricted between movable block 103 and a roller 101
Pressure section 104, in order that movable block can adapt to flexural deformation of the test specimen during bend test, the of the present embodiment
A kind of mode is：
The pressure section 104 is elastomer (such as elastic rubbery body).In the present embodiment, pressure section can be caused for elastomer
In bend test, test specimen forces pressure section to deform upon because of flexural deformation, it is possible thereby to so that movable block can adapt to examination
Flexural deformation of the part during bend test, to avoid the diastrophic intervention to test specimen, it is ensured that bend test it is normal
Carry out.
Additionally, in the present embodiment, it would however also be possible to employ the following second way is so that movable block can adapt to test specimen curved
Flexural deformation in bent process of the test：Each movable block 103 be provided in by under predetermined coaction just slidably so that：
Before bend test, test specimen 20 is restricted between movable block 103 and a roller 101；
In bend test, test specimen 20 forces movable block 103 to make to be slided away from a roller 101 because of flexural deformation.
Above-mentioned first kind of way and the second way may be used alone, can also be used in combination.
Each fixture block 102 is provided with the chute 105 extended along the thickness direction Z of test specimen, and each movable block 103 is also included slidably
Be installed on slide section 106 in chute 105, the slide section 106 is also elastomer, and slide section 106 and pressure section 104 are one
Body.In the present embodiment, chute is T-slot, and slide section is T-shaped.
Prop up the width Y of the length direction parallel to test specimen of roller 101；
Each fixture block 102 is provided with slide opening 107, described roller 101 pass through the slide opening 107 so that fixture block 102 slidably
It is placed on outside a roller 101.In the present embodiment, the section of a roller 101 is rounded, therefore, slide opening 107 is circular port.
Each support component 10 also includes a horizontal plate 108 and a riser 109 stood on horizontal plate 108, each support component
Roller 101 be connected to the end of riser 109, the slideway 110 connected with slide opening 107, riser are additionally provided with each fixture block 102
109 pass through the slideway 110, and fixture block 102 can be prevented from rotating around a roller 101 by arranging slideway 110.
Each fixture block 102 is respectively provided with the first threaded fastener 111 that can be locked in the fixture block 102 on riser 109.This reality
In applying example, unscrew after the first threaded fastener 111 i.e. spacing of the fixture block 102 of scalable two on the width Y of test specimen, wait to adjust
After section is finished, two fixture blocks 102 are fixed on riser 109 by tightening the first tight threaded fastener 111.
The horizontal plate 108 of each support component is provided with the bar shaped adjustment hole 112 extended along the length direction X of test specimen.
In the present embodiment, the quantity that the bar shaped adjustment hole 112 on the horizontal plate of each support component is shown in figure is 2,
However, the quantity of the bar shaped adjustment hole 112 on the horizontal plate of each support component is not limited to be counted shown in figure, such as each
The quantity of the bar shaped adjustment hole 112 on the horizontal plate of support component can be 1,3,4 etc..
Each bar shaped adjustment hole 112 is respectively provided with the second threaded fastener 113, and two support components 10 are by the second threaded fastener
113 are fixably attached on a workbench 30.In the present embodiment, unscrew the i.e. support of scalable two after the second threaded fastener 113
Spacing of the component 10 on the length direction X of test specimen, it is to be regulated finish after, tighten two by the second tight threaded fastener 113
Support component 10 is fixed on workbench 30.
In the present embodiment, the first threaded fastener 111 and the second threaded fastener 113 can be screw, bolt etc..
Glass used in the display screen of the test specimen 20 including mobile terminal, for example touch panel glass (TP glass) and/
Or display module glass (LCM glass).
The test specimen 20 of the present embodiment can be glass or other fragile materials.
The tool of the present embodiment is applicable to dynamic bending test, just can survey with reference to shock testing machine (i.e. pressure blessing device)
Try out the Dynamic MOR of lamellar test specimen.
The tool combination of the present embodiment is very flexible and changeable, the test specimen sample that can test various sizes with continually varying.
The riser and horizontal plate of the present embodiment can be formed with duralumin or other intermetallic composite coatings, be installed to general shock testing machine
On the workbench of equipment.
The fixture block and movable block of the present embodiment can play spacing effect, and test specimen unrest can be prevented before bend test
It is dynamic.
In bend test, test specimen is stressed and accommodates the certain active force of device applying, due to the inertia force of test specimen itself
The supporting force of the roller on direction and two support components is conversely, form dynamic bending process；Add when pressure accommodates device impact
When speed reaches some numerical value, the bending stress of test specimen will reach the breakdown strength of itself, and test specimen is just destroyed, this
When the strain of corresponding test specimen be exactly test specimen limiting threshold value.During experiment, strain testing is carried out to test specimen, or it is right
Experiment carries out analogue simulation, it is possible to directly or indirectly obtain the Dynamic MOR of test specimen.
The tool of the implementation case is flexible and changeable, is adapted to different length, width, test specimen (such as rectangle examination of thickness
Part).User can be relatively easy to the Dynamic MOR for obtaining test specimen.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit this utility model
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model
Protection domain within.
