[0002] The thickness of cast-in-place floor slabs is an important indicator for evaluating the safety performance of buildings, and is increasingly valued by relevant national departments and real estate developers. After the house is basically completed, a series of tests are required on the internal structure of the house. Among them, the thickness of the roof slab is an important indicator, and testing tools are required to conduct quality inspections on it.

[0003] According to a Chinese patent with publication number CN213688152U, a portable construction engineering quality detector is disclosed.

At the same time, the slider can squeeze the spring when it moves, so that the spring is compressed, which is convenient for the subsequent pushing of the slider and the movable block to reset and move.

[0010] Furthermore, both sides of the interior of the first measuring cylinder are provided with limiting grooves, and the limiting blocks are adapted to the limiting grooves.

[0011] By adopting the above technical solution, after the limiting block is moved into the corresponding limiting groove, the second measuring cylinder can be limited to prevent the second measuring cylinder from moving randomly.

[0020] Furthermore, the top end of the threaded shaft extends to the top of the baffle and is connected to a knob, and the threaded shaft is threadedly connected to the second measuring cylinder.

[0021] By adopting the above technical solution, it is convenient for the user to rotate the threaded shaft through the knob, so that the threaded shaft can move up and down and drive the pressing block to move.

[0022] Furthermore, the movable block is slidably connected to the sliding groove via a sliding block.

[0023] By adopting the above technical solution, when the movable block moves, it will drive the sliding block to slide inside the sliding groove, thereby improving the stability of the movable block when moving.

[0025] By adopting the above technical solution, the second measuring cylinder can slide inside the first measuring cylinder, so that the second measuring cylinder can be pulled out from the first measuring cylinder.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model is provided with a storage assembly.

When the detector is not needed, the movable shaft can be rotated in the opposite direction to make the threaded column rotate in the opposite direction, thereby driving the scale cylinder to move upward, so that the scale cylinder is moved into the storage cavity, thereby achieving the purpose of storing the scale cylinder, reducing the overall volume of the detector, and improving the convenience of carrying the detector, thereby achieving the effect of facilitating the carrying of the detector;

[0028] 2. The utility model is provided with a clamping assembly, and when the second measuring cylinder needs to be moved, the threaded shaft can be rotated to make the threaded shaft move up and reset, and then drive the pressure block to move up and reset, and the pressure block no longer presses the movable block, and the movable block resets and moves and drives the limit block to move out of the limiting groove. At this time, the second measuring cylinder is no longer limited, and then the second measuring cylinder can be moved, which is convenient for adjusting its position. After the adjustment is completed, the limit block is aligned with the limit groove, and the threaded shaft is rotated in the opposite direction, so that the pressure block moves down and pushes the movable block to move in the direction of the limit groove.

The threaded column 903 rotates to drive the scale cylinder 901 to move downward, so that the scale cylinder 901 is moved out of the first measuring cylinder 1. Then, the scale cylinder 901 is inserted into the hole opened on the roof. The U-shaped clamping plate 7 is used to limit it on one side of the bottom of the hole, so that the thickness of the roof can be measured through the scale lines 10 on the scale cylinder 901.

[0049] When the detector is not in use, the movable shaft 905 can be rotated in the opposite direction to make the threaded column 903 rotate in the opposite direction, thereby driving the scale cylinder 901 to move upward, so that the scale cylinder 901 is moved into the storage chamber 904, thereby achieving the purpose of storing the scale cylinder 901, and then the second measuring cylinder 2 is moved into the first measuring cylinder 1 and the second measuring cylinder 2 is limited, so that the size of the detector can be reduced and the detector can be carried conveniently.
