[0028] The utility model provides a kind of readable floor thickness rapid measurement device.

[0029] Embodiment one:

[0030] As Figures 1-3 It includes pipe ruler 1 and slide bar 2, and the slide bar 2 is slidably inserted into the inside of the pipe ruler 1, so that the slide bar 2 can slide up and down in the inside of the pipe ruler 1, the outer surface of the bottom end of the pipe ruler 1 is provided with two symmetrical notches 11, the inside of the two notches 11 is rotatably connected with support arm 3, by rotating the support arm 3, it can be stretched, as Figure 1 And Figure 2As shown, the two supporting arms 3 can also be retracted into the gap 11 by rotating the supporting arms 3. Figure 3 As shown, the bottom end of the slide rod 2 is fixedly connected with a top rod 21. When the two supporting arms 3 are in the unfolded state, the top rod 21 can be used to press down the end of the supporting arms 3 inside the pipe ruler 1 by sliding the slide rod 2 downward, so that the end of the supporting arms 3 outside the pipe ruler 1 is folded upward. The outer surface of the pipe ruler 1 is provided with a vertical sliding groove 12, and the outer surface of the slide rod 2 is fixedly installed with a limiting block 4 which is slidingly connected inside the sliding groove 12. When the slide rod 2 slides up and down inside the pipe ruler 1, the limiting block 4 slides up and down inside the sliding groove 12. The sliding groove 12 limits the up-and-down sliding distance of the limiting block 4, thereby limiting the slide rod 2, so that the slide rod 2 cannot slide downward and cannot be pulled out upward from the pipe ruler 1. The outer surface of the pipe ruler 1 is provided with a scale line 13 for reading the thickness of the floor. The outer surface of the top end of the pipe ruler 1 is fixedly connected with a limiting rod 14. When the device is accidentally dropped from the hand during measurement, the limiting rod 14 can abut against the top of the hole drilled in the floor, thereby avoiding the problem of falling to the next floor.

[0031] The working principle of the embodiment is as follows:

[0032] Step one: Before measuring the thickness of the floor, a hole is first drilled in the floor using a drilling machine, and the size of the hole is not less than the diameter of the pipe ruler 1.

[0033] Step two: When measuring the thickness of the floor, the top end of the slide rod 2 is pinched by hand to make the device vertical, and the pipe ruler 1 slides down on the surface of the slide rod 2, so that the limiting block 4 abuts against the top end of the sliding groove 12. Then the pipe ruler 1 is inserted into the hole. When the supporting arms 3 completely pass through the hole, the device is shaken to make the supporting arms 3 unfold outward. At this time, the top surface of the end of the supporting arms 3 inside the pipe ruler 1 abuts against the bottom of the top rod 21, so that the two supporting arms 3 are in the same straight line.

[0034] Step three: The slide rod 2 is pulled upward to drive the pipe ruler 1 upward until the top surface of the supporting arms 3 abuts against the bottom surface of the floor. At this time, the user can bend down to observe the position of the scale line 13 corresponding to the surface of the pipe ruler 1 on the top surface of the floor, and read the thickness value of the floor.

[0035] Step four: After the measurement is completed, the slide rod 2 is released, and the device slides down along the hole. The limiting rod 14 abuts against the top surface of the floor, and the supporting arms 3 are separated from the bottom surface of the floor. The slide rod 2 presses down the end of the supporting arms 3 inside the pipe ruler 1 through the top rod 21, so that the two supporting arms 3 are retracted into the gap 11.

[0036] Step five: The pipe ruler 1 is pinched by hand, and then the device is pulled out of the hole upward.

[0037] Embodiment two:

[0038] Further improvements are made on the basis of embodiment one, specifically, as Figure 4 The outer surface of the slide rod 2 is provided with a threaded hole 22, one side of the limiting block 4 is fixedly connected with a screw rod 41, and the screw rod 41 is threadedly connected in the interior of the threaded hole 22, which facilitates the assembly of the limiting block 4 and the slide rod 2 during production.

[0039] As shown in Figures 5-6 The two sides of the gap 11 are provided with round holes 15, and the two sides of the supporting arm 3 are fixedly connected with positioning columns 31, and the supporting arm 3 is rotatably connected in the interior of the round holes 15 through the positioning columns 31, so that the supporting arm 3 can rotate in the interior of the gap 11.

[0040] Specifically, the inner wall of the pipe ruler 1 is provided with a slot 16 communicating with the round hole 15, when installing the supporting arm 3, the supporting arm 3 is slid upward along the bottom of the gap 11 until the positioning column 31 corresponds to the entrance end of the slot 16, then the positioning column 31 is slid along the slot 16, and finally inserted into the round hole 15, and the entrance end of the slot 16 is inclined upward, when the slide rod 2 is installed, the top rod 21 at the bottom end of the slide rod 2 will block the slot 16, so that the positioning column 31 cannot slide out of the round hole 15 through the slot 16, ensuring the stability of the structure connection.

[0041] When assembling the device, the method is as follows:

[0042] Step one, slide the supporting arm 3 upward along the bottom of the gap 11 until the positioning column 31 corresponds to the entrance end of the slot 16, then slide the positioning column 31 downward along the inclined slot 16, and finally insert it into the round hole 15;

[0043] Step two, insert the slide rod 2 into the pipe ruler 1, then rotate the slide rod 2 to make the threaded hole 22 correspond to the sliding groove 12, then the limiting block 4 can be threadedly connected in the threaded hole 22 through the screw rod 41, and the limiting of the slide rod 2 is completed, and the assembly of the device is also completed.
