Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a roadbed detects uses thickness measurement device, includes base 1, base 1 fixed connection dipperstick 2, and 2 surfaces of dipperstick adopt red pigment to draw length scale mark, and the minimum scale of length scale mark is 0.1cm, and the scale reading of length scale mark descends from last down. Dipperstick 2 cup joints sliding sleeve 3, and sliding sleeve 3 can be free slide on dipperstick 2. The front side wall of the sliding sleeve 3 is fixedly connected with a hinge shaft 4, the hinge shaft 4 is rotatably matched with a support rod 5, and the length of the support rod 5 is sixty centimeters, so that the requirement of measuring the thickness of a common roadbed is met.

The front side wall of the sliding sleeve 3 is fixedly connected with a first magnetic block 6, the support rod 5 is fixedly connected with a second magnetic block 7, the support rod 5 is further fixedly connected with a base 8, and the base 8 is fixedly connected with a third magnetic block 9. As shown in fig. 2, when the first magnetic block 6 magnetically attracts the second magnetic block 7, the stay bar 5 is in a horizontal state; when the first magnetic block 6 magnetically attracts the third magnetic block 9, the stay bar 5 is in a vertical state. That is, the maximum rotation angle of the first magnetic block 6 for restricting the stay bar 5 is ninety degrees, and the stay bar 5 is rotated ninety degrees and then parallel to the measuring scale, so that the occupied space of the measuring device can be reduced, and the measuring device is convenient to carry. The base 8 is used for changing the magnetic pole orientation of the third magnetic block 9, so that after the brace 5 rotates ninety degrees, the magnetic pole of the third magnetic block 9 is opposite to the magnetic pole of the first magnetic block 6, and the brace 5 is adsorbed and fixed in a relatively stable manner after rotating ninety degrees.

Both ends all are equipped with extension rod 10 about vaulting pole 5, and extension rod 10 sliding fit vaulting pole 5. As shown in fig. 3, the support rod 5 is provided with a rectangular groove 11, a slide rail 12 is arranged in the rectangular groove 11, the slide rail 12 and the support rod 5 are integrally formed, the extension rod 10 extends into the rectangular groove 11 and is in clamping fit with the slide rail 12, and the bottom of the extension rod 10 and the support rod 5 are located on the same horizontal plane through the clamping fit of the extension rod 10 and the slide rail 12.
