The strapping goods such as artware.
For high latitude area, the north especially winter dryness cold climate, low temperature environment uses nylon cable tie, easily
Producing brittle failure phenomenon, therefore the brittle fracture condition of simulation cryogenic conditions test band is that band test is indispensable.
Low temperature folding quality test experiments currently for band is first fully to be absorbed water by nylon cable tie, after standing balance,
(low-temperature test chamber is the test equipment that the fields such as aviation, automobile, household electrical appliances, scientific research are indispensable, is used for put it into low-temperature test chamber again
After testing and determine the temperature environment change that electrician, electronics and other products and material carry out high temperature, low temperature or constant test
Parameter and performance, low temperature range is from 0 DEG C to-80 DEG C).Under low temperature state, band is carried out reverse 180 ° of doublings, passes through
Whether observation band ruptures and judges its low temperature folding quality.But, in the doubling test that band low temperature folding endurance test is final, real
The hands testing operator needs, by experiment window, to enter in proof box body hypothermia environment and carry out band doubling operation.This operates meeting
Cause and there is stronger cross-ventilation, test temperature balance control is caused the biggest problem, causes whole experimental situation there occurs
Certain change, reduces test accuracy.And the wrist of operator is easy to cold injury, there is certain potential safety hazard.
Summary of the invention
The deficiency existed for prior art, this utility model provide a kind of experimental data precisely, eliminate safe hidden trouble
Band low temperature folding test device.
For achieving the above object, this utility model provides following technical scheme: device is tested in a kind of band low temperature folding,
Include low-temperature test chamber, it is characterised in that: what the both lateral sides in described low-temperature test chamber was respectively symmetrically is provided with for band axle
The fixture fixing to two ends, respectively by the elastic component swung in can be at low-temperature test chamber between two fixtures and low-temperature test chamber
Connecting, in low-temperature test chamber, the space between two fixtures is the test space, and fixture is provided with one end and is connected with fixture, another
Drive rod that end extends to outside low-temperature test chamber, is provided with in the described test space and moves and position in can be at the test space
Positioning mandril.
Use technique scheme, in use, the axial two ends of band to be tested are individually fixed in fixture
On, then by drive rod, two fixtures are implemented pulling in the same direction, can be at owing to being provided with in the test space of low-temperature test chamber
The positioning mandril moved in the test space and position, therefore fixture is in drawing process, and the middle part of band can be supported with positioning mandril
Touch spacing, and after band pulls, the doubling bending of 180 degree will be formed；The most just can complete through low temperature lower the temperature after right
Folding crooked test, after completing above-mentioned steps, releases the driving force to drive rod, and fixture just can be returned by the elastic force of elastic component
Multiple to home position, the most just can start secondary, three times and test more frequently, meanwhile, positioning mandril is in the test space
Interior position carries out displacement also dependent on needs.So arranging stretches in low-temperature test chamber without operator by hands, not only makes
The precision of test is improved, and also eliminates the potential safety hazard of unexpected cold injury.
This utility model is further arranged to: fixture includes plate body, and plate body offers several connecting holes, drive rod
It is connected by connection strap with between plate body；It is provided with between described fixture and low-temperature test chamber to fix with low-temperature test chamber and is connected
Bearing, described elastic component includes axial one end and is connected with fixture, the spring that the other end is connected with bearing.
Use technique scheme, easy accessibility, simple in construction are so set.
This utility model is further set to: positioning mandril includes the body of rod and extension being inserted in low-temperature test chamber
Operating head outside low-temperature test chamber, low-temperature test chamber is positioned at the body of rod and is provided with the guide rail adaptive with the body of rod.
Use technique scheme, so setting to be easy to the position to positioning mandril and implement mobile, make operator in reality
Operation during testing is more convenient.
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the A-A generalized section of Fig. 1.
Detailed description of the invention
A kind of band low temperature folding test device described as shown in Figure 1, Figure 2, includes low-temperature test chamber 1, low-temperature test chamber 1
What interior both lateral sides was respectively symmetrically is provided with the fixture 2 fixing for the axial two ends of band, between two fixtures 2 and low-temperature test chamber 1
Elastic component 3 by swinging in can be at low-temperature test chamber 1 connects respectively, the interior sky between two fixtures 2 of low-temperature test chamber 1
Between be the test space 11, fixture 2 is provided with one end and is connected with fixture 2, and the other end extends to the drive rod 4 outside low-temperature test chamber 1,
The positioning mandril 5 moving and positioning it is provided with in can be at the test space 11 in the test space 11.Such scheme in use,
The axial two ends of band to be tested are individually fixed on fixture 2, then by drive rod 4, two fixtures 2 are implemented in the same direction
Pull, due to be provided with in the test space 11 of low-temperature test chamber 1 can be at the test space 11 in the positioning mandril that moves and position
5, therefore fixture 2 is in drawing process, can conflict and spacing with positioning mandril 5 in the middle part of band, and after band pulls, will shape
The doubling becoming 180 degree bends；The most just the doubling crooked test after low temperature is lowered the temperature can be completed, after completing above-mentioned steps,
Releasing the driving force to drive rod 4, fixture 2 just can be returned back to home position by the elastic force of elastic component 3, the most just can start
Secondary, three times and test more frequently, meanwhile, the position that positioning mandril 5 is in the test space 11 is entered also dependent on needs
Line displacement.So arranging stretches in low-temperature test chamber 1 without operator by hands, not only makes the precision of test be improved,
And also eliminate the potential safety hazard of unexpected cold injury.
In this utility model embodiment, fixture 2 includes plate body 21, and plate body 21 offers several connecting holes 22,
It is connected by connection strap 23 between drive rod 4 with plate body 21；Certainly, it should be noted that plate body 21 also can be by can the folder of opening and closing
Hold sheet to replace, band can be implemented clamping equally.It is provided with between fixture 2 and low-temperature test chamber 1 in this utility model embodiment
The bearing 6 that be connected fixing with low-temperature test chamber 1, elastic component 3 includes axial one end and is connected with fixture 2, and the other end is with bearing 6 even
The spring connect.
Positioning mandril 5 in this utility model embodiment includes the body of rod 51 being inserted in low-temperature test chamber 1 and extends
Operating head 52 outside low-temperature test chamber, low-temperature test chamber 1 is positioned at the body of rod 51 and is provided with and the guide rail 12 of the body of rod 51 adaptation.When
So, it should be noted that also can be positioned on low-temperature test chamber 1 at the test space 11 and arrange several laid out in parallel and and the body of rod
