DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 , the utility model provides a technical solution:

[0022] A device for measuring and leveling the thickness of poured concrete comprises a connecting rod 101 and a handle 201 of a strip structure, wherein the two ends of the handle 201 are respectively connected to a first support 301 and a second support 401 of a hollow structure, the connecting rod 101 is sequentially passed through the first support 301 and the second support 401, and the two ends of the connecting rod 101 are respectively connected to a scale rod 501 and a cutting rod 502, the scale rod 501 extends out of the first support 301, and the cutting rod 502 extends out of the second support 401; a leveling plate 601 is provided at the end of the second support 401 away from the first support 301, and the cutting rod 502 passes through the leveling plate 601; an adjusting mechanism is provided on the second support 401, which can adjust the axial displacement of the cutting rod 502 to control the extension amount of the cutting rod 502 out of the second support 401.

[0023] Specifically, the adjustment mechanism includes a driving mechanism, a ratchet 707 mechanism and a driving gear 701. The second support 401 is rotatably connected to the first rotating shaft 702. The driving gear 701 is arranged on the first rotating shaft 702. The implantation rod 502 is provided with a tooth structure 703 meshing with the driving gear 701. The driving mechanism is arranged on the first support 301 and is used to drive the first rotating shaft 702 to rotate. When the extension amount of the implantation rod 502 out of the second support 401 is adjusted, the ratchet 707 mechanism prevents the first rotating shaft 702 from rotating.

[0024] Specifically, the driving mechanism includes a second rotating shaft 704 , and a driving gear 705 and a driven gear 706 meshing with each other. The second rotating shaft 704 is rotatably connected to the second support 401 ; the driving gear 705 is arranged on the second rotating shaft 704 , and the driven gear 706 is arranged on the first rotating shaft 702 .

[0025] In order to facilitate the control of the rotation speed of the driving gear 701 so that the cutting rod 502 can be slowly extended out of the leveling plate 601, by cooperating with the scale rod 501, it is convenient to accurately control the extension amount of the cutting rod 502 out of the leveling plate 601. During design, the diameter of the driven gear 706 and the diameter of the driving gear 701 are both larger than the diameter of the driving gear 705. In this way, when the driving gear 705 rotates one circle, the driven gear 706 and the driving gear 701 have not rotated one circle, and the rotation speed of the driven gear 706 is lower than the rotation speed of the driving gear 705, so that the cutting rod 502 can be slowly extended out of the leveling plate 601.

[0026] Specifically, the ratchet 707 mechanism includes a ratchet 707, a pawl 708, and an elastic strip 709 disposed on the second support 401. The ratchet 707 is disposed on the second rotating shaft 704, and the pawl 708 is rotatably disposed on the second support 401. The pawl 708 is always engaged with the pawl 708 under the action of the elastic strip 709. The pawl 708 is always in an engaged state with the pawl 708 under the elastic force of the elastic strip 709, so that Figure 3 When viewed from the left, the ratchet 707 cannot rotate clockwise; if the ratchet 707 wants to rotate counterclockwise, it needs to overcome the pressure of the pawl 708. If the elastic pressure strip 709 applies enough pressure to the pawl 708, the ratchet 707 will not easily rotate counterclockwise, the second shaft 704 will not rotate, the corresponding driving gear 701 will not rotate, and the vertical displacement of the insertion rod 502 will be fixed.

[0027] In order to facilitate the movement of the pawl 708 and to facilitate the control of the pawl 708 when the pawl 708 needs to be separated from the ratchet wheel 707, a lever 801 is installed on the pawl 708. Figure 2 As shown, when the pawl 708 needs to be separated from the ratchet wheel 707 , the lever 801 is pressed downward, and the pawl 708 can be separated from the ratchet wheel 707 .

[0028] After the extension amount of the cutting rod 502 extending out of the leveling plate 601 is adjusted, in order to further prevent the axial displacement of the connecting rod 101 from changing, a positioning bolt 901 is installed on the first support 301, and the positioning bolt 901 can abut against the connecting rod 101 or the scale rod 501. When the axial displacement of the cutting rod 502 needs to be adjusted, the positioning bolt 901 is loosened, and the connecting rod 101 can move on the support. After adjustment, the positioning bolt 901 is tightened to make the positioning bolt 901 abut against the connecting rod 101 or the scale rod 501.

[0029] In order to facilitate observation of the extension amount of the cutting rod 502, a scale is provided on the scale rod 501.

[0030] Working principle:

[0031] When it is necessary to adjust the extension amount of the cutting rod 502 from the leveling plate 601, for example, if the pouring thickness of the concrete in the template needs to be 200mm, the extension amount of the cutting rod 502 from the leveling plate 601 needs to be 200mm. First, loosen the positioning bolt 901 so that the connecting rod 101 can move in the direction of its own axis. Figure 2 and Figure 3 , and then rotate the second rotating shaft 704. The rotation of the second rotating shaft 704 drives the driving gear 705 to rotate, and the driven gear 706 and the driving gear 701 rotate accordingly. The driving gear 701 engages with the toothed structure 703 so that the cutting rod 502 can move up and down. In the process of adjusting the extension amount of the cutting rod 502 extending out of the leveling plate 601, observe the scale on the scale rod 501 at the same time to determine the extension amount of the cutting rod 502 extending out of the leveling plate 601. When the extension amount of the cutting rod 502 extending out of the leveling plate 601 is adjusted, due to the existence of the ratchet 707 mechanism, the vertical displacement of the cutting rod 502 is fixed. Then tighten the positioning bolt 901 to ensure the stability of the entire device.

[0032] After the concrete is poured, insert the cutting rod 502 into the unsolidified concrete, so that the bottom end of the cutting rod 502 abuts against the inner bottom wall of the template and is vertical, and then observe the distance or gap between the leveling plate 601 and the concrete. If there is a gap between the leveling plate 601 and the concrete, it is necessary to inject a certain amount of concrete into the template; if the leveling plate 601 is submerged in concrete, it is necessary to dig out part of the concrete, and then use a plastering iron plate to level it to the thickness of the designed drawing board. And so on, find a point for each square, and finally form a leveling control network to ensure that the error between the entire construction board thickness and the board thickness designed in the drawing is minimized.

[0033] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
