Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1: This example aims to propose a rolling gauge tool for on-site engineering quantity surveying.

The flipping section includes a connecting rod 10, which is rotatably connected to the groove. The connecting rod 10 can flip up and down in the groove. An auxiliary roller is provided on the connecting rod 10, and a second locking member is provided in the groove.

[0050] The second locking component includes two insertion holes 901, a locking hole, and a locking bolt. Both insertion holes 901 are located on the front side of the rotating connecting frame and are connected to the groove. The insertion holes 901 are respectively located at the upper and lower ends of the connecting frame. The locking hole is located on the connecting rod 10. When the connecting rod 10 is rotated to the point where the connecting section is parallel, the locking hole and the adjacent insertion hole 901 are positioned in a front-to-back correspondence. The locking bolt is inserted into the adjacent insertion hole 901 and is threadedly connected to the locking hole.

[0051] The lower end of the connecting rod 10 is fixedly connected to a second telescopic rod. The second telescopic rod is vertically arranged and can extend and retract in the up and down direction. An auxiliary roller is arranged on the telescopic end of the second telescopic rod.

[0052] The second telescopic rod includes a rotating connecting frame 11 and a sliding rod 14 extending in the vertical direction. The upper surface of the rotating connecting frame 11 is provided with a sliding groove with an upper opening. The sliding rod 14 is slidably connected in the sliding groove.

[0054] Working principle: During use, the auxiliary roller 12 can be flipped up and down according to different usage conditions. When the ground is relatively hard, the user can unscrew the locking bolt, then flip the auxiliary roller 12 downward, and then insert the locking bolt into the insertion hole 901 on the lower side to lock the connecting rod 10.

[0055] This allows the auxiliary roller 12 to provide auxiliary rolling support for the roller 8 during rolling, enabling the roller 8 to be supported at two points during rolling, providing greater lateral friction and preventing the roller 8 from deflecting during rolling.

[0056] When the ground is soft or uneven, the user can unscrew the locking bolts to flip the auxiliary roller 12 upwards, thus allowing the auxiliary roller 12 to be folded.

[0057] During the rolling process on the ground, when the auxiliary roller 12 encounters a protrusion or stone, the auxiliary roller 12 is pushed upward by the force, which causes the second telescopic rod to extend and retract, thereby preventing the auxiliary roller from being pushed up by the protruding stone and the roller 8 from losing contact with the ground, which would cause an error in the number of rotations of the roller 8.

[0058] This allows the auxiliary roller 12 to be quickly flipped and folded to adapt to different usage scenarios. At the same time, the auxiliary roller 12 can provide auxiliary rolling support for the roller 8 to prevent the roller 8 from shifting. Furthermore, the extension and retraction of the second telescopic rod can prevent the roller 8 from leaving the ground when the auxiliary roller 12 is lifted, thus reducing errors.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
