detailed description

The utility model will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

Example 1:

Shown in conjunction with accompanying drawing 1-5, a kind of new roadbed slope ruler, comprises the base ruler 1 that is used to be close to the slope surface, the level ruler 2 that is used for reading and the angle plate 3, described base ruler 1, level ruler 2 and The angle plate 3 is sequentially connected by a double-ended screw 4 with a nut, and one end of the screw 4 is provided with a wing nut 5 for fastening; as shown in Figure 5, the dial 3 is provided with a 0° scale line An angle line 31 parallel to the bottom edge of the base ruler 1; as shown in Figure 4, the level 21 used for leveling the level ruler 2 is fixedly installed on the level ruler 2, and the center line of the level ruler 2 is provided with a The reading line 22.

Here the principle of the utility model is further elaborated:

When closed, the center line of the base ruler 1, the reading line 22 of the level ruler 2 and the 0° scale line of the angle disc 3 coincide on a straight line; The level bar 2 uses a level 21 to make the level bar 2 tend to be horizontal, then tighten the wing nut 5 to fix the angle of the level bar 2 and the base bar 1, and the reading set on the center line of the level bar 2 The line 22 is aligned with the angle line 31 on the angle disk 3, and the angle value represented by the angle line 31 is read out, which is the angle value of the measured slope angle.
