DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 、 Figure 2 As shown, a device for measuring the thickness of cast concrete floor slabs includes a main body 1, which is a quadrangular prism-shaped rod structure. A measuring rod 2 is connected to the lower end of the main body 1. The sidewalls of the measuring rod 2 are provided with scale lines 201. The lower end of the measuring rod 2 is provided with at least three support claws 202 along the circumference to ensure that the measuring rod 2 remains upright after being inserted into the concrete. A measuring plate 3 is provided on one side of the measuring rod 2. The measuring plate 3 is arranged horizontally and positioned above the concrete when in use. An indicator ring 302 is connected to one end of the measuring plate 3, which cooperates with the measuring rod 2. A guide plate 301 is connected to the upper end of the measuring plate 3, which slides upward and downward with the main body 1. A pressure plate 4 is connected to the upper end of the main body 1 to secure the guide plate 301. A handle 101 is connected to the sidewalls of the main body 1.

[0025] An angle plate 106 for fixing the guide plate 301 is provided on the side wall of the main body 1 . The angle plate 106 positions the guide plate 301 so that the guide plate 301 slides up and down along the main body 1 .

[0026] like Figure 3 As shown, the upper end of the main body 1 is provided with a clearance groove 103, the side wall of the main body 1 is provided with a guide groove 105, the guide groove 105 is provided with a guide column 104, and the two sides of the pressure plate 4 are provided with a slider 401 that cooperates with the guide groove 105. Figure 5 As shown, the lower end of the pressure plate 4 is connected to a push plate 405 that cooperates with the guide column 104. The outer side of the guide column 104 is covered with a spring 102 that pushes the push plate 405. Under the action of the spring 102, the end of the pressure plate 4 is always pressed on the guide plate 301.

[0027] In order to facilitate opening, an anti-slip groove 402 is provided on the upper end surface of the pressing plate 4.

[0028] like Figure 4 As shown, in order to increase the friction, a pressure block 403 is provided at one end of the pressure plate 4, and an anti-sliding block 404 that cooperates with the guide plate 301 is connected to the side wall of the pressure block 403. The anti-sliding block 404 is made of rubber block, which can greatly increase the friction between the guide plate 301 and ensure the reliability of the fixation of the guide plate 301.

[0029] The indicator ring 302 is a semicircular ring structure, which makes it easy to observe the scale.

[0030] The length of the guide plate 301 is not less than the sum of the lengths of the main body 1 and the measuring rod 2 , ensuring that the anti-sliding block 404 will not separate from the guide plate 301 .

[0031] During use, grip the handle 101 and use your thumb to slide the pressure plate 4 backward, separating the anti-slip block 404 from the guide plate 301. Insert the measuring rod 2 into the concrete. During insertion, the measuring plate 3 is positioned horizontally, so it remains above the concrete. Once the support claws 202 contact the bottom of the concrete, release the pressure plate 4. The anti-slip block 404 presses the guide plate 301 in place. Remove the device from the concrete and observe the corresponding scale on the indicator ring 302, which represents the concrete thickness. After each measurement, rinse the device promptly to prevent concrete from condensing on it and affecting its next use.

[0032] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
