Preferably, the scales on the first scale plate and the second scale plate are on the same horizontal plane.

Preferably, the placing box is a cube without a top cover.

Preferably, the rest pad is a concave semicircle.

Preferably, the laser emitter control switches and the placing box are arranged right opposite to each other in the vertical direction, and the number of the laser emitter control switches is three.

Preferably, the first scale plate and the second scale plate are vertically arranged at the upper end of the base.

Advantageous effects

1. The utility model provides a current light beam plane method have the operation difficulty, and the structure is complicated, has certain error and fixed the placing and does not put just scheduling problem.

2. Secondly, the first scale plate and the second scale plate are arranged to compare and read the reflection condition of light in the measuring process, so that the flatness of the lens is judged.

3. Moreover, the case of placing that is equipped with puts the lens that needs the measurement through placing the case top and stacks up placing of placing the bottom of the case portion, can fix the lens and make it more stable to reduce in the measurement and rock the error that has reduced in the measurement.

Fig. 2 is a perspective view of the structure placing box of the present invention.

In the drawings, the corresponding relationship between the component names and the reference numbers is as follows: base 1, scale plate 2, two 3, bracing piece 4, roof 5, laser emitter control switch 6, dead lever 7, place the case 8, place pad 9, control panel 10, reflection light-permeable groove 11.

Detailed Description

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

as shown in fig. 1-2;

the present embodiment provides a periscope lens plane measuring apparatus, including: base 1, scale plate one 2, scale plate two 3, bracing piece 4, roof 5, laser emitter control switch 6, dead lever 7, place case 8, place pad 9, control panel 10, reflection light-permeable groove 11, the welding of base 1's upper end left side has bracing piece 4, bracing piece 4's right-hand member base 1's upper end fixedly connected with scale plate two 3, scale plate two 3's right-hand member base 1's upper end fixedly connected with dead lever 7, the upper end of dead lever 7's right-hand member base 1 is equipped with scale plate one 2, bracing piece 4's upper end fixedly connected with roof 5, roof 5's inside is equipped with laser emitter control switch 6, the upper end of dead lever 7 is equipped with places case 8, the inside bottom of placing case 8 is equipped with places pad 9, the left and right sides of placing case 8 is equipped with reflection light-permeable groove 11, base 1.

Wherein, the scale on scale plate one 2 and the scale plate two 3 is on same horizontal plane, and the same scale setting on both sides is the level of conveniently observing when the reverberation passes through reflection light transmission groove 11 with light reflection to scale plate one 2 and the scale plate two 3 on and judges the lens.

Wherein, it is the square that does not have the top cap to place case 8, and the top of placing case 8 does not set up the top cap and is conveniently put into placing case 8 with the lens, makes its process simple swift more.

Wherein, place pad 9 and be sunken semi-circular, sunken semi-circular can be better fixed lens, makes it more stable, reduces the error in the measurement process.

Wherein, laser emitter control switch 6 with place case 8 just to setting up in vertical direction, and laser emitter control switch 6 is equipped with threely, but the reflection measurement is carried out in the both ends and the centre of the three laser emitter control switch 6 a pair of lens that sets up to obtain the result on scale plate one 2 and scale plate two 3.

Wherein, the vertical setting of scale plate 2 and scale plate two 3 is in base 1 upper end, and the vertical setting of two scale plates is the light that better receipt sent through laser emitter control switch 6, and the reflection through the lens reflects light on the scale plate 2 and the scale plate two 3 of two vertical settings.

The working principle is as follows: on putting into the pad 9 of placing in placing case 8 the lens that will need measuring in the use, fix the lens through placing the recess on the pad 9, then open laser emitter control switch 6 through control panel 10, laser emitter control switch 6 will shine both sides and the centre of lens, reflect the light on both sides to scale plate one 2 and scale plate two 3 through reflection printing opacity groove 11, through with ideal reflection light scale go on comparing and whether the plane degree of lens is judged at same scale mark, close laser emitter control switch 6 after the measurement is accomplished, take out the lens, repeat above-mentioned step when carrying out next measurement.
