Description
Technical field
The utility model belongs to test equipment technical field, and in particular to a kind of nano-cellulose film stretching clamp.
Background technology
Nano-cellulose film and its laminated film are a kind of new membrane materials and composite, are dried by suction filtration, molding
Dry obtained nano-cellulose film or by the compound obtained laminated film of nano-cellulose film and high polymer material have intensity it is high,
The performance that thickness is small, surface is smooth.In recent years, with the development of science and technology, increasing field needs high intensity, surface smooth
Nano-cellulose membrane material and its composite, nano-cellulose with increasing high polymer material, graphene material
Material etc. prepares composite film material.
The nano-cellulose film obtained using suction filtration, molding drying, generally first carries out suction filtration, then by nanofiber solution
Wet nano-cellulose thin slice is clipped between glass plate or wire netting the nano-cellulose film thickness for carrying out drying and shaping, obtaining
It is smooth compared with small, surface and intensity is big.
Nano-cellulose film is prepared by sample, and when the sample of preparation carries out tension test, overall length is in 3~5cm
Between, because sample is shorter, when filling sample, also more it is difficult, except the edge of de-clamping, sample span is small, existing stretching
Fixture is difficult to fill sample.
When carrying out tension test, existing fixture can not often be held fixedly nanofiber in use
Plain film, sample is easily slipped, and is often occurred not breaking and is caused the phenomenon of experiment termination due to slipping, so that can not be for nanometer
Cellophane carries out tension test.
Utility model content
Goal of the invention：For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of nanofiber
Plain film stretching clamp, nano-cellulose film and its composite are carried out mechanical test, particularly surface smoother,
The thin slice that thickness is less than 150 microns is clamped.
Technical scheme：In order to realize foregoing invention purpose, the technical solution adopted in the utility model is：
A kind of nano-cellulose film stretching clamp, including the upper fixture and lower clamp being used in conjunction with each other；Described is upper
Fixture includes top connection, upper locking nut, upper specific and the first hold assembly, and top connection is specifically connected with upper, and in top connection
On set upper locking nut, the first hold assembly is located at particularly；Lower clamp include lower contact, lower locking nut, it is lower specific and
Second hold assembly, lower contact is specifically connected with lower, and sets in lower contact locking nut, and the second hold assembly is located at lower tool
On body.
The first described hold assembly be installed in upper two pieces of grip blocks particularly, respectively go forward grip block and it is upper after
Grip block, goes forward grip block and upper rear grip block adjusts relative position by short screw.
Ripple is set on the described clamping face gone forward between grip block and upper rear grip block.
The second described hold assembly is two pieces of grip blocks under particularly, after respectively descending front clamp plate and being lower
Grip block, lower front clamp plate and lower rear grip block adjust relative position by long bolt.
Ripple is set on clamping face between described lower front clamp plate and lower rear grip block.
In use, described top connection is connected with equipment crossbeam, described lower contact is arranged on clamping fixture seat.
Beneficial effect：Compared with prior art, nano-cellulose film stretching clamp of the present utility model, in upper fixture
Short screw and long bolt structure is respectively adopted with lower clamp, can so avoid fixture close to when interfere, convenient clamping is special
It is not the clamping of short sample.Meanwhile, the folder sample position of clamp body uses corrugated jaw up and down, and clamping is reliable, and can guarantee that disconnected
Point is good.It is applicable the extension test experiment of small sample.It is using scope：Maximum test force：200N；Gripping width：≤10mm；Folder
Hold thickness：≤3mm.

Embodiment
The utility model is described further with reference to specific accompanying drawing.
As Figure 1-4, nano-cellulose film stretching clamp of the present utility model, including structure identical upper fixture 1
With 2 two parts of lower clamp, upper fixture 1 and lower clamp 2 are used in conjunction with each other.Wherein, upper fixture 1 includes top connection 11, locked
The hold assembly of tight nut 12, upper specific 13 and first, top connection 11 is connected with upper specific 13, and sets in top connection 11 locking
Nut 12, the first hold assembly is located on specific 13；First hold assembly is two pieces of grip blocks on upper specific 13,
Respectively go forward grip block 6 and upper rear grip block 7, go forward grip block 6 and upper rear grip block 7 adjusts relative position by short screw 4
Put, ripple 8 is set on the clamping face gone forward between grip block 6 and upper rear grip block 7.
Equally, lower clamp includes lower contact 21, lower locking nut 22, lower specific 23 and second hold assembly, lower contact 21
It is connected with lower specific 23, and sets in lower contact 21 locking nut 22, the second hold assembly is located on lower specific 23；Second folder
It is two pieces of grip blocks on lower specific 23 to hold part, respectively descends front clamp plate 9 and lower rear grip block 10, lower front clamp
Plate 9 and lower rear grip block 10 adjust relative position, the folder between lower front clamp plate 9 and lower rear grip block 10 by long bolt 5
Hold and ripple 8 is set on face.
Nano-cellulose film stretching clamp of the present utility model, short screw 4 is respectively adopted in upper fixture 1 and lower clamp 2
With the structure of long bolt 5, can so avoid fixture close to when interfere, convenient clamping, the clamping of particularly short sample.Together
When, the folder sample position of clamp body up and down（Jaw）Using corrugated jaw, clamping is reliable, and can guarantee that breakpoint is good, effective gram
The phenomenon of sample skidding is taken.
Upper fixture, when in use, is first inserted equipment crossbeam ten by nano-cellulose film stretching clamp of the present utility model
