detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

The embodiment of the portable tool for measuring floor thickness in the utility model is shown in Fig. 1-3.

Example 1

The portable tool for measuring floor thickness in this embodiment includes a fixed ruler 1 and a sliding ruler 2. The fixed ruler 1 includes a probing ruler 11 for extending into the floor and a measuring ruler 12 for measuring the thickness of the floor. The measuring ruler 12 is provided with a scale, and the head of the sliding ruler 2 is provided with a pointer 21 cooperating with the scale to indicate the floor thickness indication.

The tail of the sliding ruler 2 is provided with a fixed ring 22 that cooperates with the probing ruler 11 so that the fixed ruler 1 can move back and forth along the sliding ruler 2 . The two ends of the fixed ring 22 are provided with support rods 23, so as to support the sliding ruler 2 when measuring the thickness of the floor slab, and prevent the sliding ruler 2 from falling into the floor hole when the floor hole is too large to cause inaccurate measurement results, and the support rod 23 is in contact with the sliding ruler 2. Feet 2 vertical. The head of the sliding ruler 2 is provided with a handle 24 to facilitate the movement of the sliding ruler 2 .

The measuring ruler 12 is provided with a fixing device 3 to fix the relative position between the sliding ruler 2 and the fixed ruler 1 . The fixing device 3 includes a fixing groove 31 and a screw 33 arranged on the measuring ruler 12 , and the fixing groove 31 is arranged on a side away from the scale on the measuring ruler 12 . The fixed groove 31 is a hollow structure surrounded by the first groove plate 311 and the second groove plate 312 on both sides, the first groove plate 311 is a plate-like structure perpendicular to the measuring ruler 12, the second groove plate 312 is an L-shaped plate, and the second groove plate 312 312 includes a vertical plate 313 perpendicular to the measuring ruler 12 and a horizontal plate 314 perpendicular to the vertical plate 313 , and the horizontal plate 314 is arranged opposite to the measuring ruler 12 . The sliding ruler 2 is inserted in the fixing groove 31 and slides back and forth in the fixing groove 31 . The groove plate 1 311 of the fixing groove 31 is provided with a fastening hole 32 for the screw 33 to pass through.
