Technical Field

[0001] The utility model relates to the technical field of measuring calipers, in particular to a caliper for measuring the thickness of a floor slab. Background Art

[0002] Building is a general term for buildings and structures. With the continuous development of the construction industry, the acceptance of structural engineering has become more and more stringent. In the process of building construction, the thickness of the building floor formed by pouring needs to be measured, and calipers are one of the tools for measuring the thickness of the floor.

[0003] A Chinese patent application numbered CN 209857790 U discloses a floor thickness measuring caliper, comprising a ruler, a slide groove being provided on the surface of the ruler, a scale being provided on the surface of the slide groove, a first fixed ruler being installed at the bottom end of the rear surface of the ruler, a rotating shaft being installed at one end of the first fixed ruler close to the ruler, a second fixed ruler being rotatably connected to the front surface of the ruler, and a fixed column being installed at the right end of the second fixed ruler.

[0004] However, the length of the measuring caliper in the above prior art is not adjustable. When the floor is high, personnel often need to climb up to measure, and personnel need to measure along the edge, which may cause the risk of falling. Therefore, a floor thickness measuring caliper is needed. Summary of the invention

[0005] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a floor thickness measuring caliper to solve the problem that the length of the existing measuring caliper cannot be adjusted. When the floor is high, personnel often need to climb up to measure, and personnel need to measure at the edge, which puts them at risk of falling.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A floor thickness measuring caliper comprises a main telescopic rod, an auxiliary telescopic rod and a U-shaped clamp, the telescopic end of the main telescopic rod is installed with the U-shaped clamp, the main telescopic rod is installed with a fixed block, the fixed block is provided with a second rod hole, the second rod hole is penetrated by an auxiliary telescopic rod, the telescopic end of the auxiliary telescopic rod is installed with a clamp, the clamp is used in conjunction with the U-shaped clamp, the fixed end of the auxiliary telescopic rod is installed with a sliding block, the sliding block is provided with a third rod hole, the fixed end of the main telescopic rod penetrates the third rod hole and a thickness scale line is provided on the outer wall of the main telescopic rod, and an observation port is provided on the sliding block opposite to the thickness scale line.

[0008] Furthermore, the main telescopic rod includes a main rod barrel, a main rod body and a first locking screw. The main rod barrel is slidably matched with the main rod body. The first locking screw is installed on the main rod barrel, and the first locking screw abuts against the main rod body.

[0009] Furthermore, the auxiliary telescopic rod includes an auxiliary rod barrel, an auxiliary rod body and a second locking screw. The auxiliary rod barrel is slidably matched with the auxiliary rod body. The second locking screw is installed on the auxiliary rod barrel, and one end of the second locking screw abuts against the auxiliary rod body.

[0010] Furthermore, a handle is installed on one side of the sliding block, thereby making it convenient for personnel to adjust the sliding block 6.

[0011] Furthermore, an alignment line is provided on the sliding block, thereby facilitating personnel to determine the movement amount of the sliding block 6 .

[0012] Furthermore, a level bubble is installed on the main telescopic rod, which makes it convenient for personnel to observe whether the measuring caliper is level and reduces measurement errors.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model can slide the sliding block along the main telescopic rod through the handle. The sliding block drives the clamping plate and the U-shaped clamping body to clamp the floor from one side through the auxiliary telescopic rod. At this time, the personnel only need to observe the movement of the sliding block on the main telescopic rod to measure the thickness of the floor. Only one person is required to operate, which saves time and effort.

[0015] 2. The main telescopic rod and the auxiliary telescopic rod of the utility model adopt a telescopic design, which is convenient for personnel to adjust the height of the measuring caliper according to the height of the floor slab, so as to meet the thickness measurement needs of floors at different heights. There is no need for personnel to perform high-altitude measurements, making the measurement process safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The main telescopic rod 1 includes a main rod barrel 101 , a main rod body 102 and a first locking screw 103 . The main rod barrel 101 is slidably matched with the main rod body 102 . The first locking screw 103 is installed on the main rod barrel 101 , and the first locking screw 103 abuts against the main rod body 102 .

[0026] The auxiliary telescopic rod 2 includes an auxiliary rod barrel 201 , an auxiliary rod body 202 and a second locking screw 203 . The auxiliary rod barrel 201 and the auxiliary rod body 202 are slidably matched. The second locking screw 203 is installed on the auxiliary rod barrel 201 , and one end of the second locking screw 203 abuts against the auxiliary rod body 202 .

[0027] A handle 7 is installed on one side of the sliding block 6, so that people can adjust the sliding block 6 conveniently.

[0028] An alignment line 14 is provided on the sliding block 6 , thereby facilitating personnel to determine the movement amount of the sliding block 6 .

[0029] A level bubble 8 is installed on the main telescopic rod 1, which makes it convenient for personnel to observe whether the measuring caliper is level and reduces measurement errors.

[0030] The working principle of the utility model is as follows: during measurement, the personnel holds the main telescopic rod 1 with one hand and the handle 7 with the other hand, and then slides the sliding block 6 upward along the main telescopic rod 1 by holding the handle 7 until the splint 4 reaches the column U-shaped clamp 3.
