Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the adjustable cast-in-situ floor thickness controller is composed of a handle 1, a vertical rod 2, an adjustable indicating member 3, an anti-falling member 4 and other components.

Handle 1 adopts long 100mm, and diameter 10 mm's plain steel muscle is made, and handle 1 transversely puts, and welded fastening is passed through on the top of pole setting 2 at the middle part, and during the welding, the high hf =5mm of welding seam of control handle 1 and pole setting.

The upright rod 2 is made of smooth round steel bars with the length of 1000mm and the diameter of 10mm, and a graduated scale is arranged on the surface of the upright rod.

The adjustable indicating component 3 is composed of a hoop 3-1, a mark post 3-2, a nut 3-3 and a fastening bolt 3-4, and is shown in figure 2. The hoop 3-1 is U-shaped, a clamping groove with an opening at one end is formed between the two arms, and the hoop 3-1 is sleeved on the vertical rod 2 through the clamping groove. The marker post 3-2 comprises a left unit cross rod and a right unit cross rod, the two unit cross rods are located at the same horizontal height and on the same straight line, and vertical rods 2 of the two unit cross rods are perpendicular and respectively fixed on the outer sides of two arms of the hoop 3-1. The nut 3-3 is arranged at the end opening of the clamping groove of the hoop 3-1, the nut 3-3 is vertically arranged, the central axis of the screw hole of the nut is vertical to the upright rod, and the left side and the right side of the nut 3-3 are fixedly connected with the inner sides of two arms of the hoop 3-1; the fastening bolt 3-4 is arranged in the nut 3-3, the head part of the fastening bolt faces outwards, and the tail part of the fastening bolt can abut against the upright rod 2 through screwing. The clamp 3-1 can be pressed against the upright 2 by screwing the set screw 3-4, fixing it in a predetermined position.
