Description
Technical field
The utility model is related to a kind of pencil hardometer, for the case hardness performance test of paint film, paint film.
Background technology
Pencil hardometer is a kind of indispensable test equipment in the industries such as coating, paint, plastic cement spraying, passes through plough
The pencil hardness grade of rupture of membranes layer measures film hardness, is the specific purpose tool for measuring film hardness index.At present, market
On pencil hardometer it is complicated, when test, is cumbersome, and working efficiency is relatively low, and manufacturing cost is high, so as to cause to invest
On waste.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of pencil hardometer, the pencil is hard
Degree meter is simple in structure, easy to operate, working efficiency is high, and manufacturing cost is low.
In order to realize above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions：
A kind of pencil hardometer, including hardometer ontology, the hardometer ontology is cuboid, on the hardometer ontology
Inclined through-hole is offered, the through-hole runs through the top and bottom of the hardometer ontology, and the side of the hardometer ontology opens up
There is threaded hole, screw is provided in the threaded hole, the threaded hole is connected with the through-hole, the rear end of the hardometer ontology
It is provided through the rotation axis of hardometer ontology, the both ends of the rotation axis are equipped with idler wheel, and the rotation axis can be relative to
Hardometer ontology rotates, and is vertically arranged with fixed link on the hardometer ontology, circular hole counterweight is cased in the fixed link.
Further, the wheel face of the idler wheel is covered with one layer of rubber.
The beneficial effects of the utility model are：
A kind of pencil hardometer described in the utility model is simple in structure, and manufacturing cost is low, reduces cost of investment, is surveying
During examination, move the pencil hardometer with hand push and at the uniform velocity move, operation is very easy, and testing efficiency is high, saves the time；Simultaneously
Fixed link is provided with above the pencil hardometer, circular hole counterweight can be added as needed in fixed link, due to circular hole counterweight
It can require to be replaced according to the loading of test, so the program can meet the loading requirement of different test cases.
Description of the drawings
Structure diagram when Fig. 1 is utility model works；
Reference numeral therein is：1-hardometer ontology；2-through-hole；3-screw；4-rotation axis；5-idler wheel；6—
Fixed link；7-circular hole counterweight；8-rubber；9-pencil.
Specific embodiment
The technical solution of the utility model is further explained below in conjunction with drawings and examples, but below interior
Appearance is not used in restriction the scope of protection of the utility model.
As shown in Figure 1, the utility model provides a kind of pencil hardometer, the hardometer ontology 1 including cuboid, hardness
The through-hole 2 in 45 degree of inclinations angle, through-hole 2 with 1 upper and lower surface of hardometer ontology are offered on meter ontology 1 and runs through hardometer ontology 1
Top and bottom, for through-hole 2 for being inserted into pencil, the side of hardometer ontology 1 offers threaded hole (not shown), in threaded hole
Screw 3 is provided with, threaded hole is connected with the through-hole, and the rear end of hardometer ontology 1 is provided through the rotation of hardometer ontology 1
Axis 4, the both ends of rotation axis 4 are equipped with idler wheel 5, and rotation axis 4 can be rotated relative to hardometer ontology 1, are erected on hardometer ontology 1
Fixed link 6 directly is provided with, circular hole counterweight 7 is cased in fixed link 6.The utility model is simple in structure, and manufacturing cost is low, reduces throwing
Cost is provided, in test, the pencil hardometer is moved with hand push and at the uniform velocity moves, operation is very easy, and testing efficiency is high, saves
Time；Fixed link is provided with above the pencil hardometer simultaneously, can be added as needed on circular hole counterweight in fixed link, by
It can be required to be replaced according to the loading of test in circular hole counterweight, so the loading that the program can meet different test cases will
It asks.
Preferably, the wheel face of the idler wheel 5 is covered with one layer of rubber 8 by one as the utility model；Rubber is as buffering
Design, it is more steady when rolling idler wheel 5, so as to ensure to measure safer, measurement accuracy higher.
Operating process when the utility model measures is as follows：
(1) according to GB/T9271《Paint and varnish standard test plate (panel)》Regulation prepares ground.
(2) pencil 9 is cut to 5~6 millimeters of lead for retractable pencil (cylinder for keeping lead for retractable pencil) is exposed, keeps pencil 9 vertical with sand paper
With reconditioning lead for retractable pencil end face, until end face, into complete circle, edge does not crush or notch.Pencil 9 is every time before use, will be through
Cross such reconditioning.
(3) unless otherwise prescribed, it is measured under 23 ± 2 DEG C and 50 ± 5% damp conditions.
(4) pencil 9 is inserted into through-hole 2, rotary screw 3 will be mounted with the utility model of pencil 9 to fix pencil 9
Pencil hardometer lie in measured surface, at this time three point contact measured surface (2 points be idler wheel 5, a little be pencil-lead), use
Hand push hardometer ontology 1, idler wheel 5 move at least 7 millimeters with the speed of 0.5~1 mm/second, paint film not to be made to occur 3 millimeters
And the mark hardness of the most hard pencil 9 of Yi Shang cut represents the pencil hardness of paint film.
(5) parallel determination is secondary, if secondary measurement result is inconsistent (difference is more than 1 pencil hardness unit), Ying Chong
It does experiment.
Circular hole counterweight 7 can be added during test in fixed link 6 as needed.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but not to this practicality newly
The limitation of type protection domain, those skilled in the art should understand that, on the basis of the technical solution of the utility model, ability
Field technique personnel do not need to make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
In enclosing.
