Compared with the prior art, the utility model discloses a set up looks articulated fixed plate and grip block to and the spring of connection fixed plate and grip block, can conveniently hang the plastics exemplar in order to carry out plastics exemplar drop test.
Description
Technical field
The utility model relates to a kind of device for plastics impact test, particularly relates to a kind of fixture for plastics exemplar fall-down test.
Background technology
When plastics impact strength refers to that plastic material is impacted suddenly and ruptures, the measuring of energy of material absorbable on per unit xsect, the ability of its reflection plastic material shock resistance effect, be an index weighing plastic material toughness, plastics impact strength is little, means that plastic material is more crisp.General exemplar plastic material to be tested being made into standard is tested.The method of plastics exemplar impact test has multiple, wherein a kind of for plastics exemplar is hung on different specified altitude assignments by fixture, then plastics exemplar is decontroled, plastics exemplar freely falls, fall on metal base plate, also claim plastics exemplar fall-down test, according to the state of plastics exemplar after fall-down test, evaluate the plastics impact strength of this plastic material.In the prior art, in plastics exemplar fall-down test, also do not have to hang plastics exemplar easily to carry out the fixture of plastics exemplar impact test.
Utility model content
The utility model is intended to solve above-mentioned mentioned technical matters, provides a kind of fixture for plastics exemplar fall-down test, can hang plastics exemplar easily to carry out plastics exemplar impact test.
The utility model is realized by following technical scheme: a kind of fixture for plastics exemplar fall-down test, comprise fixed head, grip block and spring, the middle part of fixed head and grip block is hinged, fixed head comprises stiff end and the first bare terminal end, grip block comprises folding end and the second bare terminal end, in 30 ° ~ 60 ° angles between folding end and stiff end, one end of spring connects folding end, and the other end is connected and fixed end.
Preferably, the middle part of grip block is installed with semicircular first projection, the middle part of fixed head is provided with the first groove of cooperation first projection, the through end of the first groove is provided with the baffle plate be fixed on fixed head, is provided with the bearing pin of through baffle plate and the first projection at the axle center place of the first projection vertically.
Preferably, the end face that stiff end is close with folding end is provided with columniform second groove for fixing spring and the 3rd groove, in the second groove and the 3rd groove, the first pad being used for linking springs and the second pad are set respectively, first pad and the second pad are arranged respectively the circular projection of the end being used for buckle spring, be respectively arranged with the second projection and the 3rd projection of buckle spring at the sidewall of the second groove and the 3rd groove.
Preferably, the magnetic devices attracted each other after stiff end and folding end are relatively set with energising.
The beneficial effects of the utility model are: compared with prior art, a kind of fixture for plastics exemplar fall-down test of the present utility model, by arranging the fixed head and grip block that are hinged, and be connected and fixed the spring of plate and grip block, plastics exemplar can be hung easily to carry out plastics exemplar fall-down test.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the sectional view at an a kind of fixture visual angle for plastics exemplar fall-down test of the present utility model.
Embodiment
As shown in Figure 1, a kind of fixture for plastics exemplar fall-down test, comprise fixed head 1, grip block 2 and spring 5, the middle part of fixed head 1 and grip block 2 is hinged, fixed head 1 comprises stiff end 11 and the first bare terminal end 12, and grip block 2 comprises folding end 21 and the second bare terminal end 22, in 30 ° ~ 60 ° angles between folding end 21 and stiff end 11, one end of spring 5 connects folding end 21, and the other end is connected and fixed end 11.
The middle part of grip block 2 is installed with semicircular first projection 23, the middle part of fixed head 1 is provided with the first groove 13 of cooperation first projection 23, the through end of the first groove 13 is provided with the baffle plate be fixed on fixed head 1, is provided with the bearing pin 6 of through baffle plate and the first projection 23 at the axle center place of the first projection 23 vertically.
The end face that stiff end 11 is close with folding end 21 is provided with columniform second groove 3 for fixing spring 5 and the 3rd groove 4, the first pad 31 and the second pad 41 being used for linking springs 5 is set respectively in the second groove 3 and the 3rd groove 4, first pad 31 and the second pad 41 are arranged respectively the circular projection of the end being used for buckle spring 5, be respectively arranged with the second projection 32 and the 3rd projection 42 of buckle spring 5 at the sidewall of the second groove 3 and the 3rd groove 4.The magnetic devices 7 that stiff end 11 and folding end 21 attract each other after corresponding position is also provided with energising.
Spring 5 is in its pre-compressed state when clamping, there is compression stroke, precompressed spring 5 withstands the stiff end 11 of fixed head 1 and the folding end 21 of grip block 2, because the middle part of fixed head 1 and grip block 2 is hinged, then the first bare terminal end 12 and the second bare terminal end 22 extruding also grip plastic exemplar mutually.When carrying out plastics exemplar fall-down test, to magnetic devices 7 power supply, the magnetic devices 7 being positioned at stiff end 11 and folding end 21 correspondence position is attracted each other, then further Compress Spring 5 makes the first bare terminal end 12 be separated with the second bare terminal end 22, and plastics exemplar falls.
Above embodiment is only not limited in order to the technical solution of the utility model to be described, all do not depart from the utility model spirit and scope any amendment or equivalently to replace, it all should be encompassed in the scope of technical solutions of the utility model.
