Description

A kind of instrument for the torsional strength measuring plastics

Technical field

The invention belongs to the technical field of performance test of plastics, are specifically related to a kind of instrument of torsional strength for measuring plastics Device.

Background technique

Product made of plastics is when in use, it is sometimes necessary to certain torsion force can be born, to prevent plastic cement system Product torsional deflection when in use.Currently, the common testing methods of measurement plastics mechanical property have tensile strength test, bending strength Test, impact strength test, compressive strength test, hardness test etc..The mechanical property such as bending strength, hardness by measurement plastics It can reflect to a certain extent the non-deformability of plastics, but cannot accurately measure the ability of plastics anti-torsion deformation, Therefore, it is necessary to design, one kind is easy to use, structure is simple, low cost, torsional strength easy to carry, can accurately measuring plastics Instrument.

Summary of the invention

It is an object of the invention to overcome the deficiencies in the prior art described above, a kind of torsional strength of measurement plastics is provided Instrument, simple structure and reasonable design and be simple to manufacture, manufacturing cost is low, easy to carry, can effectively measure the anti-of plastics Turn round intensity.

To achieve the above object, the technical solution adopted by the present invention is that: it is a kind of measure plastics torsional strength instrument, It is characterized in that: including pillar, calibration loop, handle, outer race, bearing ball, the bearing inner ring, torsion being set on the base Body, pointer, key pin, convex block, torque spanner, the pedestal, pillar, calibration loop, handle, outer race are to be fixedly connected, described Pointer, key pin, convex block are fixedly connected on torsion body, and the key pin of the torsion body side surface is stuck in the groove of bearing inner ring inner surface In, the center of the upper surface of the pedestal, the center of the lower surface of torsion body respectively have one to be used to block plastics batten both ends Rectangular channel, the spanner of the torque spanner cover on the convex block at the center of torsion body upper surface.

The instrument of the torsional strength of above-mentioned a kind of measurement plastics, it is characterised in that: the pedestal, pillar, calibration loop, hand Handle, outer race, bearing ball, bearing inner ring, torsion body, pointer, key pin, convex block, torque spanner are metal material.

Compared with the prior art, the present invention has the following advantages:

1, the present invention by plastics batten torque spanner twisting resistance effect under, plastics batten when being torqued into certain angle, The torque value shown on torque spanner measures the torsional strengths of plastics.

2, the torsional strength of the measurable plastics of the present invention, is except these routines such as tension load, bending load, compressive loads Except mechanical property of the method to measure plastics, the twisting resistance of plastics can be measured in terms of other side is torsional load Learn performance.

3, the present invention is easy to use, and easy to carry, structure is simple, is simple to manufacture, low cost, is conducive to promote the use of.

Below by drawings and examples, the present invention is described in further detail.

Specific embodiment

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, the present invention includes the pillar 2 being arranged on pedestal 1, calibration loop 8, hand Handle 3, outer race 4, bearing ball 5, bearing inner ring 6, torsion body 7, pointer 9, key pin 12, convex block 10, torque spanner 11, it is described Pedestal 1, pillar 2, calibration loop 8, handle 3, outer race 4 are to be fixedly connected, and the pointer 9, key pin 12, convex block 10 are fixedly connected Torsion body 7 on, it is described torsion 7 side of body key pin 12 be stuck in the groove of 6 inner surface of bearing inner ring, the pedestal 1 it is upper Respectively there are the rectangular channel for being used to block 13 both ends of plastics batten, the torsion in the center on surface, the center of the lower surface of torsion body 7 The spanner of torque wrench 11 covers on the convex block 10 at the center of torsion 10 upper surface of body.

In the present embodiment, the pedestal 1, pillar 2, calibration loop 8, handle 3, outer race 4, bearing ball 5, bearing inner ring 6, reversing body 7, pointer 9, key pin 12, convex block 10, torque spanner 11 is metal material.

The operation principle of the present invention is that: in use, torque spanner is removed from convex block, integral torsion will be fixedly connected with Swivel, pointer, key pin, convex block take out from bearing inner ring, by the center of the upper surface of the lower end inserted base of plastics batten In rectangular channel, will be fixedly connected while integral torsion body, pointer, key pin, convex block are fitted into bearing inner ring makes plastic-like In the rectangular channel at the center of the lower surface of the upper end insertion torsion body of item, the spanner of torque spanner is covered on convex block, left hand is held The firmly handle on calibration loop, the right hand holds torque spanner rotation and is fixedly connected with integral convex block and torsion body, when on torsion body Pointer when pointing to certain scale on calibration loop, the torque value shown on torque spanner is bigger, illustrates the antitorque of plastics batten Intensity is better.

The above is only presently preferred embodiments of the present invention, is not intended to limit the invention in any way, it is all according to the present invention Technical spirit any simple modification, change and equivalent structure transformation to the above embodiments, still fall within skill of the present invention In the protection scope of art scheme.
