Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

The embodiment of the utility model discloses a light instrument for measuring floor thickness is shown in fig. 1-3.

Example 1

The light instrument for measuring floor thickness of this embodiment, including fixed ruler 1 and slip chi 2, fixed ruler 1 is including the dipperstick 12 that is used for stretching into the visit chi 11 of floor and is used for measuring floor thickness. The measuring scale 12 is provided with scales, and the head of the sliding scale 2 is provided with a pointer 21 which is matched with the scales to indicate the thickness indication of the floor slab.

The tail part of the sliding ruler 2 is provided with a fixing ring 22 matched with the extension ruler 11 so that the fixing ruler 1 moves back and forth along the sliding ruler 2. The two ends of the fixing 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 slab hole to cause inaccurate measuring results when the floor slab hole is too large, and the support rods 23 are perpendicular to the sliding ruler 2. The sliding ruler 2 is provided with a handle 24 at the head for moving the sliding ruler 2 conveniently.

The measuring scale 12 is provided with a fixing device 3 to fix the relative position between the sliding scale 2 and the fixed scale 1. The fixing device 3 includes a fixing groove 31 provided on the measuring scale 12 and a screw 33, and the fixing groove 31 is provided on a side away from the scale on the measuring scale 12.
