[0001] The invention relates to the technical field of building construction, in particular to a device for accurately judging the flatness of a floor. Background Art

[0002] For the floor of large workshops and underground garages in construction projects, wear-resistant floor is often used. Large-area floor has high flatness requirements, and different workshops and underground garages have different flatness requirements for the floor. Because the workshops are filled with heavy machinery and equipment, uneven ground will affect the working performance of the equipment. In addition, there will be forklifts driving back and forth, and forklifts also have very high requirements for the flatness of the ground. According to the national standard, the flatness requirement for the concrete surface layer is 2m±5mm, and the flatness requirement for the paint surface layer is 2m±2mm.

[0003] In the past, flatness detection devices used to perform detection using a level ruler and a plug gauge. When both ends of the level ruler were in contact with the ground, the plug gauge was used to detect the gap between the middle of the level ruler and the ground. The detection was cumbersome and not suitable for detection of a large range of factory floors. Moreover, it could only simply infer that the flatness was insufficient, and could not perform accurate flatness detection according to different flatness requirements. Summary of the invention

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] In the present invention, the moving bracket drives the fixed housing to move on the floor. When the flatness of the floor is certain, the balance ball and the balance rod remain horizontal, and at this time the warning light is not on. When the floor is uneven, the moving bracket and the fixed housing drive the electrode plate to tilt.

[0027] By disengaging the limiting rod from the adjusting rod to cancel the rotational limit of the adjusting rod, and then turning the adjusting rod, the adjusting rod drives a set of adjusting rotating shafts to rotate, and through the cooperation of the synchronous pulley and the synchronous belt, drives the other set of adjusting rotating shafts to rotate synchronously. At this time, the first movable block and the second movable block move towards or away from each other, thereby driving the guiding connecting rod and the electrode plate to move up or down. At this time, according to the position of the guiding connecting rod driving the adjusting pointer at the adjusting scale, the contact angle between the electrode plate and the balance ball is judged, so as to adjust the warning of the floor tilt angle, so as to be suitable for the acceptance work of different floor flatness.

When the balancing ball contacts the first positive electrode sheet and the first negative electrode sheet, the first warning light is connected, and the first warning light is on, while the second warning light is off. At this time, the floor is tilted toward the direction of the first warning light. When the balancing ball contacts the second negative electrode sheet and the second positive electrode sheet, the second warning light is connected, and the second warning light is on, while the first warning light is off. At this time, the floor is tilted toward the direction of the second warning light, so as to accurately determine the tilt direction of the floor.

[0029] By pressing the closing button, the closing button drives the button connecting rod to move, and the button connecting rod drives the lever and the positioning rod to move, and the lever presses the limit movable block toward the holding spring through the inclined surface of the limit groove, and the limit sliding block cooperates with the limit sliding groove to horizontally limit the limit movable block, and then the lever enters the innermost side of the limit groove, at this time, the holding spring holds the limit movable block to reset, and the limit groove and the lever cooperate to limit and fix the button connecting rod connected to the closing button. At this time, the positioning plate set on the surface of the positioning rod limits the balance rod, thereby preventing the balance rod from contacting the balance ball and the electrode sheet, thereby closing the device and canceling the detection of floor flatness. On the contrary, by pressing the detection button, the lever connected to the warning light contacts the reset groove, thereby driving the limit movable block to move toward the holding spring after rubbing. At this time, the button spring connected to the closing button pushes the closing button to pop out, thereby canceling the limit on the balance rod, thereby opening the device and starting the detection of floor flatness.

[0045] The electrode sheet 22 includes a first positive electrode sheet 2201, a second negative electrode sheet 2202, a second positive electrode sheet 2203 and a first negative electrode sheet 2204. The first positive electrode sheet 2201 and the second positive electrode sheet 2203 are respectively connected to the two groups of first movable blocks 1601, the second negative electrode sheet 2202 and the first negative electrode sheet 2204 are respectively connected to the two groups of second movable blocks 1602, and the first positive electrode sheet 2201 is located directly above the second negative electrode sheet 2202, and the second positive electrode sheet 2203 is located directly above the first negative electrode sheet 2204.

At this time, the second warning light 302 lights up and the first warning light 301 does not light up. At this time, the floor is tilted toward the direction of the second warning light 302.

[0047] Embodiment three:

[0048] like Figure 4-6 As shown, the device for accurately judging the flatness of a floor disclosed in the third embodiment of the present invention has a structure that is basically the same as that in the second embodiment, and the difference lies in the precise adjustment of the warning of the floor inclination angle. A limit rod 6 is inserted at the top of the fixed shell 2, and an adjustment limit groove 23 is provided at the top of the adjustment rod 7. One end of the limit rod 6 is inserted into the adjustment limit groove 23. A guide groove 9 is provided on the front side of the fixed shell 2.

One end of the guide connecting rod 15 is connected to the adjustment movable block 16, and the other end extends out of the guide groove 9 and is connected to the adjustment pointer 8, and an adjustment scale 10 is provided on the front side of the fixed shell 2.

[0049] By disengaging the limiting rod 6 from the adjusting rod 7, the rotational limit of the adjusting rod 7 is cancelled. Then, by turning the adjusting rod 7, the adjusting rod 7 drives a set of adjusting rotating shafts 17 to rotate. And through the cooperation of the synchronous pulley 24 and the synchronous belt 25, it drives another set of adjusting rotating shafts 17 to rotate synchronously. At this time, the first movable block 1601 and the second movable block 1602 move towards or away from each other, thereby driving the guiding connecting rod 15 and the electrode plate 22 to move up or down. At this time, according to the position of the adjusting pointer 8 driven by the guiding connecting rod 15 at the adjusting scale 10, the contact angle between the electrode plate 22 and the balance ball 31 is judged, so as to adjust the warning of the floor tilt angle, and thus it can be adapted to the acceptance work of different floor flatness.

[0050] Embodiment 4:

[0051] As Figure 2-7 shown, the device for accurately judging the floor flatness disclosed in Embodiment 4 of the present invention has basically the same structure as that in Embodiment 3. The difference lies in the limitation of the balance rod 30. A closing button slot 14 and a detection button slot 11 are opened on the front side of the fixed housing 2. A detection button 4 is slidably arranged in the detection button slot 11, and a closing button 5 is slidably arranged in the closing button slot 14. Elastic linkage members are arranged between the detection button 4 and the detection button slot 11 and between the closing button 5 and the closing button slot 14. The elastic linkage member includes a button spring 12, a button connecting rod 13 and a lever 27. The button spring 12 is arranged inside the detection button slot 11 and the closing button slot 14. One end of the button spring 12 is connected to the detection button slot 11 and the closing button slot 14, and the other end is connected to the detection button 4 and the closing button 5. One end of the button connecting rod 13 is connected to the detection button 4 and the closing button 5, and the other end penetrates into the fixed housing 2 and is connected to the lever 27, and the lever 27 is arranged vertically.

[0052] A clamping rod 33 is arranged at the middle end of the button connecting rod 13 connected to the closing button 5. A clamping plate 34 is arranged on one side of the clamping rod 33 close to the balance rod 30. A limiting movable block 20 is horizontally arranged in the fixed housing 2. A limiting sliding groove 19 is opened in the fixed housing 2. A limiting sliding block 26 is arranged at the position of the limiting movable block 20 corresponding to the limiting sliding groove 19, and the limiting sliding block 26 is slidably arranged in the limiting sliding groove 19. One end of the limiting movable block 20 is provided with a holding spring 18, and the other end of the holding spring 18 is connected to the fixed housing 2. The other end of the limiting movable block 20 is connected to a blocking rod 21. A limiting groove 2001 and a reset groove 2002 are opened on the surface of the limiting movable block 20. The side of the limiting groove 2001 close to the lever 27 has a right trapezoidal structure, and the side far from the lever 27 has a "匚" shaped structure. The reset groove 2002 has a right trapezoidal structure, and the width and depth of the second negative electrode plate 2202 are equal to the width and depth of the first positive electrode plate 2201.

[0053] By pressing the closing button 5, the closing button 5 drives the button connecting rod 13 to move, and the button connecting rod 13 drives the lever 27 and the locking rod 33 to move, and the lever 27 presses the limiting movable block 20 toward the holding spring 18 through the inclined surface of the limiting groove 2001, and the limiting slider 26 cooperates with the limiting slide groove 19 to horizontally limit the limiting movable block 20, and then the lever 27 enters the innermost side of the limiting groove 2001. At this time, the holding spring 18 holds the limiting movable block 20 to reset, and the limiting groove 2001 cooperates with the lever 27 to limit and fix the button connecting rod 13 connected to the closing button 5. At this time, the locking rod 33 is locked. The locking plate 34 arranged on the surface of the positioning rod 33 limits the balancing rod 30, thereby preventing the balancing rod 30 from contacting the balancing ball 31 and the electrode sheet 22, thereby closing the device and canceling the detection of the floor flatness. Conversely, by pressing the detection button 4, the lever 27 connected to the warning light 3 contacts the reset groove 2002, thereby driving the limiting movable block 20 to move toward the supporting spring 18. At this time, the button spring 12 connected to the closing button 5 supports the closing button 5 to pop outward, thereby canceling the limit on the balancing rod 30, thereby opening the device and starting the detection of the floor flatness.

[0054] The specific plan is:

[0055] By disengaging the limit rod 6 from the adjustment rod 7, the rotation limit of the adjustment rod 7 is cancelled, and then the adjustment rod 7 is twisted, so that the adjustment rod 7 drives a group of adjustment shafts 17 to rotate, and drives another group of adjustment shafts 17 to rotate synchronously through the cooperation of the synchronous wheel 24 and the synchronous belt 25. At this time, the first movable block 1601 and the second movable block 1602 move toward or away from each other, thereby driving the guide connecting rod 15 and the electrode sheet 22 to move up or down. At this time, the contact angle between the electrode sheet 22 and the balance ball 31 is judged according to the position of the adjustment pointer 8 driven by the guide connecting rod 15 to the adjustment scale 10, so as to adjust the floor inclination angle warning, so as to adapt to different floor flatness acceptance work;

[0056] The first positive electrode sheet 2201 and the first negative electrode sheet 2204 are connected to the first warning light 301 through a cable, and the second negative electrode sheet 2202 and the second positive electrode sheet 2203 are connected to the second warning light 302 through a cable. When the balancing ball 31 contacts the first positive electrode sheet 2201 and the first negative electrode sheet 2204, the first warning light 301 is connected. At this time, the first warning light 301 lights up, and the second warning light 302 does not light up. At this time, the floor is tilted toward the direction of the first warning light 301. When the balancing ball 31 contacts the second negative electrode sheet 2202 and the second positive electrode sheet 2203, the second warning light 302 is connected. At this time, the second warning light 302 lights up, and the first warning light 301 does not light up. At this time, the floor is tilted toward the direction of the second warning light 302, and the tilt direction of the floor is accurately determined;

[0057] By pressing the closing button 5, the closing button 5 drives the button connecting rod 13 to move, and the button connecting rod 13 drives the lever 27 and the locking rod 33 to move, and the lever 27 presses the limiting movable block 20 toward the holding spring 18 through the inclined surface of the limiting groove 2001, and the limiting slider 26 cooperates with the limiting slide groove 19 to horizontally limit the limiting movable block 20, and then the lever 27 enters the innermost side of the limiting groove 2001. At this time, the holding spring 18 holds the limiting movable block 20 to reset, and the limiting groove 2001 cooperates with the lever 27 to limit and fix the button connecting rod 13 connected to the closing button 5. At this time, the locking rod 33 is locked. The locking plate 34 arranged on the surface of the positioning rod 33 limits the balancing rod 30, thereby preventing the balancing rod 30 from contacting the balancing ball 31 and the electrode sheet 22, thereby closing the device and canceling the detection of the floor flatness. Conversely, by pressing the detection button 4, the lever 27 connected to the warning light 3 contacts the reset groove 2002, thereby driving the limiting movable block 20 to move toward the supporting spring 18. At this time, the button spring 12 connected to the closing button 5 supports the closing button 5 to pop outward, thereby canceling the limit on the balancing rod 30, thereby opening the device and starting the detection of the floor flatness.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
