Set of planes 120 is to enter line according to the design requirement of target to be measured and the structure of target to be measured and cut imitative type to form.
In actual applications, so that the first target to be measured is the optical cavity of backboard as an example, by a horizontal obstacle (not shown), such as one
Bar vertical bar plate or long line, the both ends of the horizontal obstacle are separately fixed on the both ends of backboard optical cavity, so that the bottom of horizontal obstacle
Face plane corresponding with the accent of backboard optical cavity is just concordant, and so, the first measurer 100 is placed in optical cavity, allows the first measurer
100 the first reference plane 110 is bonded with the bottom surface of optical cavity, manual translation first measurer 100, makes it close to horizontal obstacle,
If the first minimum limit of size measurement plane 123 of first measurer 100 by horizontal obstacle, can not illustrate the depth of optical cavity
Degree is too small, is unsatisfactory for the minimum limit of size requirement of design, similarly, such as the first maximum limit of size measurement plane 121 passes through
Horizontal obstacle, then illustrate that the depth of optical cavity is too big, be unsatisfactory for the maximum limit of size requirement of design, certainly, can be by first most
Small dimension limit measurement plane 123 but the depth that by the first maximum limit of size measurement plane 121, then can not illustrate the optical cavity
Meet design requirement.
Obviously, the measurement of the depth survey measurer operates fairly simple convenience, and then, measurement efficiency is improved, very
Practicality, low manufacture cost, service life length, especially suitable for batch production when measurement work, accordingly, greatly reduce
The manufacturing cost of backboard and the production efficiency for improving backboard, and then lift the competitiveness such as television set.
Further, as shown in Figures 1 to 4, as a kind of specific real of depth measuring device provided by the utility model
Mode is applied, the depth of the first target to be measured is more accurately judged for convenience of survey crew in which size range, the first measurement

Dimensional measurement plane 122, each second middle 125 and first minimum limit of size measurement plane of measurement plane, 123 end to end, phase
It is mutually parallel and incremented by successively with the difference in height of the first reference plane 110.
It is to be appreciated that when cutting imitative type online, the upper deviation of the depth of the first target to be measured and lower deviation are split respectively
Into multistage, so, one more accurately judges whether to meet original design requirement to facilitate, and specifically in original design requirement
In the range of which, two conveniently to improve design requirement when, can be using the first original middle measurement plane 124 as new first
Maximum limit of size measurement plane or the first minimum limit of size measurement plane, thus, beneficial to the multiple of the depth measuring device
Utilize, improve its adaptability.
In other words, the first maximum limit of size measurement plane 121, each first middle measurement plane 124, the first basic chi
Very little measurement plane 122, each second middle minimum limit of size measurement plane 123 of measurement plane 125 and first, simply it is determined that
When target to be measured and the design requirement determined, just it is to determine, if same target to be measured, after changing design requirement, Ke Nengyuan
First middle measurement plane 124 is the first new maximum limit of size measurement plane 121 of this measurement, it is also possible in second
Between measurement plane 125 be new the first minimum limit of size measurement plane 123, also cannot each middle measurement plane, always
It, each ladder plane of the first measurer 100 it is specific why measurement plane, should be decided according to the actual requirements, but usual first surveys
The first maximum limit of size measurement plane 121, the first basic size measurement plane 122 and first can be included by measuring in set of planes 120
Minimum limit of size measurement plane 123.
Further, as shown in Figures 1 to 4, as a kind of specific real of depth measuring device provided by the utility model
Mode is applied, to simplify the structure of the depth measuring device, the first maximum limit of size measurement plane 121, each first centre measure
Plane 124, the first basic size measurement plane 122, each second middle minimum limit of size of measurement plane 125 and first measurement are flat
The adjacent difference in height between any two in face 123 is equal.
As shown in Figure 2 and Figure 4, specifically in the present embodiment, the first middle 124 and second middle measurement plane of measurement plane
125 are respectively provided with one, and the difference in height between the first middle reference plane 110 of measurement plane 124 and first is H1, is surveyed among second
The difference in height measured between the reference plane 110 of plane 125 and first is h1, wherein, as shown in Fig. 2 H0 ＞ H1 ＞ H ＞ h1 ＞ h0, and
As shown in figure 4, H0-H1=H1-H=H-h1=h1-h0=a.
Accordingly, as shown in figure 3, to simplify the structure of the depth measuring device, convenient to make, the width of each measurement plane
It is identical, it is L, specifically, such as the first maximum limit of size measurement plane 121, the first middle measurement plane 124, first are basic
Dimensional measurement plane 122, the width of the second middle minimum limit of size measurement plane 123 of measurement plane 125 and first are L.

It is made it is to be appreciated that second measurer 200 can also cut imitative type by line, it is to be measured by second when cutting imitative type online
The upper deviation and lower deviation of the depth of target are divided into multistage respectively, and so, one more accurately judges whether to meet original to facilitate
First design requirement, and specifically original design requirement which in the range of, two conveniently to improve design requirement when, can be by original
The 3rd middle measurement plane come is flat as new the second maximum limit of size measurement plane or second minimum limit of size measurement
Face, thus, beneficial to the multiple utilization of the depth measuring device, improve its adaptability.
Specifically in the present embodiment, as shown in Figures 6 to 9, do not set measurement among the 3rd flat in the second measurer 200
Face (not shown) and the 4th middle measurement plane (not shown), therefrom, it may be appreciated that ground, each ladder plane of the second measurer 200
It is specific why measurement plane, and whether the 3rd middle measurement plane and/or the 4th middle measurement plane are set, should be according to reality
Depending on border needs, but generally, the second measurer 200 includes the second maximum limit of size measurement plane 221, the second basic size is surveyed
