Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, new below with reference to this practicality
Accompanying drawing in type embodiment, by detailed description of the invention, is fully described by the technical solution of the utility model.
Obviously, described embodiment is a part of embodiment of the present utility model rather than whole embodiments,
Based on embodiment of the present utility model, those of ordinary skill in the art are not making the premise of creative work
The every other embodiment of lower acquisition, within each falling within protection domain of the present utility model.
Embodiment
Fig. 2 is the structure chart of a kind of clearance test tool that this utility model provides, as in figure 2 it is shown, described
Clearance test tool include:
Test board 21；At least one lateral edges of test board 21 is circular arc, as test section 22, test section
The test board thickness of 22 gradually changes along the circumference of circular arc；The edge of test section 22 is provided with graduation mark 23,
The scale that graduation mark 23 indicates is corresponding with the thickness of test section 22.On test section 22 edge, certain some institute is in place
The scale numerical value putting the thickness of test board of correspondence graduation mark 23 sign corresponding with this point is identical.
Further, optionally, test board 21 is circular slab, and the angle of test section 22 correspondence is 180 degree.
The thickness of test section 22 between 0.1mm-2mm, and graduation mark 23 indicate scale 0.1mm-2mm it
Between；The minimum scale value of graduation mark 23 target scale is 0.02mm.Wherein, the minima of test section thickness is also
0.1mm can be less than, and more than 0mm, e.g., 0.02mm or 0.04mm etc..The thickness of test section also may be used
To be other scopes (e.g., 0.2mm-2mm), as required the thickness of the test section in test board is set
Putting, because the thickness of test section is corresponding with the scale that graduation mark indicates, therefore, the scale that graduation mark indicates is also
Can be other scopes.In the present embodiment, minimum scale value is that 0.02mm, i.e. measuring accuracy can reach
0.02mm, relative to prior art (measuring accuracy 0.1mm), measuring accuracy is greatly improved.
Optionally, when test board 21 is circular slab, the thickness of test section 22 is along the side of test board 21 radius
To keeping constant, graduation mark 23 can extend to the center of circle (not shown in Fig. 2) of test board 21.Wherein,
The length of graduation mark can be configured according to the needs of test, for the length of graduation mark and be not construed as limiting.
The reading of scale during clearance test it is more conducive to when graduation mark is longer.
On the basis of above-described embodiment, as in figure 2 it is shown, portion in addition to test section 22 on test board 21
Being divided into non-test section 24, the thickness of the non-test section 24 of test board is uniform, and the thickness of non-test section 24 is less than
The maximum of test section 22 thickness.The thickness of non-test section can be set as required, it is also possible to from saving
The thickness of non-test section is arranged less by the angle of cost.
On the basis of above-described embodiment, in fig. 2, test board is provided with handle 25.By handle 25 side
Just the axle making the test section 22 in test board pass around test board 21 center of circle in gap rotates, or
Person conveniently makes the test section 22 in test board roll in gap, reaches to test the purpose of gap length.
Wherein, the shape of handle 25 is not construed as limiting, and the quantity of handle 25 is not construed as limiting.At the present embodiment
In, handle 25 is preferably provided at the position at place, test board 21 center of circle, but, handle 25 can also be arranged
Other positions at test board 21, it is possible to realize conveniently making test board carry out rotating or rolling purpose.
It should be noted that in the present embodiment, for gap, be present in the plane of an object with another
Between the plane of one object, it is also possible to be present between two planes on an object.
When carrying out clearance measurement, the present embodiment is with to the clearance measurement between two planes on an object
As a example by illustrate, as it is shown on figure 3, testee 26 is formed gap 27, by test section by two planes
The edge of one end that 22 scales are less is put in gap 27, holds handle 25 and makes test board 21 in gap 27
Middle rotation or rolling, due to the motion of test board 21, between making the edge of the different-thickness of test section 22 enter
In gap 27, when test board 21 can not turn because of the resistance of two planes by forming gap in gap 27
When moving or roll, that in the scale corresponding to test section 22 extreme lower position that reading exposes, numerical value is bigger,
It is the size in gap；When gap is less, the scale corresponding to test section extreme lower position exposed may
Occur existing the situation of, then this scale is the size in gap.As shown in Figure 4, testee is recorded
The size in the gap 27 of two planes of 26 is 0.44mm (in Fig. 4 scale) indicated by arrow.Pass through
Above-mentioned clearance measurement tool, it is also possible to be used for the gap in the display device such as TV, display panels
Test, and above-mentioned clearance measurement tool is compared with clearance measurement tool of the prior art, assemble
Convenient, cost is relatively low, and certainty of measurement is high, it is not necessary to repeatedly attempt, time-consuming, it is simple to operation.
What deserves to be explained is, exemplary preferably circular for test board plate is stated of the present embodiment, but
The present embodiment simply a kind of example, in other embodiment of this utility model, test board can also is that other
Regular or irregular shape.Such as, as it is shown in figure 5, test board 21 is by semicircular test section 22 He
The non-test section 24 of triangle forms.It addition, during the present embodiment plate that test board is preferably circular, exemplary
Central angle corresponding for test section is 180 degree by ground, but a kind of example of the present embodiment, new in this practicality
In other embodiments of type, the optional scope of central angle that test section is corresponding is (0 °, 360 °), can basis
The needs of test are configured.Such as, as shown in Figure 6, the central angle of test section 22 correspondence is more than 180
Degree, and less than 360 degree.
In addition it is also necessary to it is noted that Fig. 2-6 provide clearance test tool structural representation in,
Gap measurement jig has many something in common, and its something in common uses identical reference in every width accompanying drawing
Illustrate, and the identical structure of clearance test tool not all has in each detailed description of the invention and retouches in detail
State, it should be appreciated by those skilled in the art that the mutually isostructural specific descriptions of clearance test tool are in description
In repeat no more, those skilled in the art can refer to the relevant clearance test tool specifically described different accompanying drawings
Understand.
Note, above are only preferred embodiment of the present utility model and institute's application technology principle.Art technology
Those skilled in the art, it will be appreciated that this utility model is not limited to specific embodiment described here, are come by personnel
Say and can carry out various obvious change, readjust and substitute without departing from protection model of the present utility model
Enclose.Therefore, although by above example, this utility model is described in further detail, but this
Utility model is not limited only to above example, in the case of conceiving without departing from this utility model, it is also possible to
Including other Equivalent embodiments more, and scope of the present utility model is determined by scope of the appended claims.
